Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a suction-type mobile vacuum cleaner for the purpose of preserving areas, especially waterways and pavements, which uses a flexible tube to remove dust and dirt contained in the air flow sucked in. The present invention relates to a vacuum cleaner comprising a suction port connected to a mechanism for separating 1411 debris and suction means.

The invention particularly relates to a method of handling waste collected by the above device.

This method is mainly used for preserving areas, warehouses and private gardens, cleaning fallen leaves, cleaning beaches and railways, polishing and finishing, removing debris from the workbench of soldering machines, using plane ground powder, and wax. Used in stationary or mobile suction cleaners for purposes such as removing dirt.

Industrial vacuum cleaners that suck in water, dirt, and other debris with air currents and mechanically separate these substances from the air flow are well known in factories and train departure halls.

The suction tube typically leads into a large cross-section settling chamber to reduce disturbance of the inhaled airflow. The resulting reduction in flow velocity causes the bulky, heavy particles to be separated by gravity.

Unfortunately, fine dust particles are not completely removed. The installation of appropriately placed baffles near the inlet and/or outlet of the deposition chamber can further remove fine dust particles.

According to the baffle plate, the air flow that is sucked in causes a sudden change in direction, and dust particles having a diameter of 50 microns or more are stopped and removed by inertia.

Industrial suction vacuum cleaners based on the cyclone effect are also well known. The known device essentially comprises a cylindrical body extending downwardly by a conical part communicating at the bottom with a funnel for collecting debris.

The center of the cyclone contains a dust tank, the walls of which are provided with a layer of filters.

The drawn-in air stream, laden with debris, dirt, debris, etc., generally flows tangentially into the cyclone in the upper cylindrical section. The centrifugal force of the decelerating cyclone brakes the dirt and dust with the annular wall of the cylindrical tank. This removes most of the dust from the drawn air stream before it reaches the filter.

If large dust is removed in advance using a cyclone, the filter layer will remain permeable for a relatively long period of time.
However, cyclone devices have the disadvantage of not being able to collect debris from sticky, cohesive materials such as mud and animal feces.

British patent number 1. No. d 72,611 discloses a road sweeper comprising a transverse flange and a transverse roller having fibers and extending diagonally and laterally over the gold plate below the frame of a commercial vehicle. Commercial vehicles are generally relatively heavy and difficult to handle.

The horizontal brushes and rollers are driven by the wheel shaft, and the suction device sucks up the debris.

These known machines are unable to reach the pavement along the curb or the pavement when a car is parked.

The present invention provides a mechanical separation device which gives the vacuum cleaner a large throughput, so that it can be used on pavements all the way to the curb, even when cars are parked. Moreover, the provided device 1 is such that this vacuum cleaner disposes of dirt and dust reliably and effortlessly.

The present invention relates to a suction type mobile vacuum cleaner for the purpose of preserving areas, especially waterways and pavements, and is used to remove dust and debris trapped in the r'A of air sucked in by a flexible tube. a suction port connected to a mechanism for separating, and suction means, the dividing mechanism being characterized in that the dividing mechanism is provided with at least one disposable, removable bag for collecting and retaining debris.

One feature of the invention is that the settling chamber, which performs the first fraction 9411 due to the gravity and possible inertia of the dust, and the cyclone, which separates the dust by centrifugal force, are provided in the same container.

The invention also relates to a method for separating dirt, dust and/or particles consisting of solids or liquids or of any material having different densities and particle sizes depending on the incoming fluid by mechanical means as described above, including gravity, Using inertia and perhaps a centrifugal force field, dirt and dust are continuously separated and collected in removable bags, which are then removed from the device, tied with strings, and stacked on the side of the road. It has many characteristics.

In a preferred embodiment of the invention, the dust is subjected to gravity and inertia due to baffles mII before the inhaled air is centrifugally treated in a cyclone or a far flood separator.

Other features of the invention will become apparent from the following detailed description and the accompanying drawings, which schematically show various embodiments of the vacuum cleaner of the invention.

In FIG. 1, a suction vacuum cleaner, indicated in its entirety by the reference numeral 1, includes a mechanical dividing device consisting of a settling chamber 2 combined with a cyclone 3. The flow of air that is sucked in, containing various types of debris such as lumps, dirt, paper scraps, fallen leaves, sand, wood, cigarette butts, animal feces, etc., enters through the suction port 4, preferably through the flexible It flows turbulently in the direction of the arrow X in the suction conduit 5 consisting of a full tube 7 and leading to the deposition chamber 2, in which the flow rate of the air or fluid sucked in decreases rapidly. In this resting place dirt and dust accumulates on the bottom of a settling chamber connected to a bag 6 which receives the dirt to assist in the removal operation.

The air flow, which has dropped heavy debris such as stone fragments, animal feces, piles of fallen leaves, and compressed paper, and contains only relatively light debris and dust particles, is decelerated by a baffle plate 7 and directed tangentially to the upper part 8 of the cyclone 3. be guided in a direction. The flow moves in a helical pattern and preferably descends to a level near the mouth 9 of the discharge pipe 1o, which is connected to the cyclone 30.

The vertical velocity component of this first spiral air flow downwards is suitable for mechanical separation and favors the separation 11 of dirt and dust towards the bottom J1 of the cyclone 3.

The airflow then undergoes a helical movement up the exhaust pipe 1o. The rising flow in the discharge qjl 10 plays no role in the separation of dust.

If the danger of entering Rotuf '12 of cyclone 3 is eliminated, mechanical separation of a large amount of debris becomes possible.

Due to the fact that certain debris sticks to the upper part 8 of the cylindrical body, the inlet 12 of the cyclone device becomes clogged unless it is previously removed in the settling chamber 2 by wetted substances, gels or mud.

The use of baffle plates (not shown) in the waste accumulation chamber can be improved depending on their location, preferably near the entrance and exit of the accumulation chamber. These baffles utilize the inertia of trash. Appropriate placement of baffle plates reduces mechanical dust removal J41
The inertia of heavy debris can be added to gravity to further propel the object.

If the sedimentation chamber for the purpose of the first-order pJIl due to gravity and the cyclone 3 are installed in the same container,
The cyclone 3 preferably comprises a removable cylindrical body 13, as shown in FIGS. 3-5. The body 13 is provided with a lid 14 having an orifice 15 for directing the inhaled air flow, and further includes a first jacket 16 and a second jacket 16.
jacket 17, the first jacket 16 is
jacket] 7/surrounded by the second jacket 17
has a trapezoidal shape and is concentric with the first jacket, along which the suction flow is a vortex flow] & a secondary air flow is introduced at a high velocity in the linear direction, and the outlet orifice 9
is a certain distance ν! from the side wall of the cylindrical body all around the jacket. It is made concentrically with the outside of the jacket and protected by a filter 9'.

41 [The device is preferably mounted on a lightweight self-propelled vehicle 18 equipped with a hydraulic motor 19, so that driving, ie, driving and controlling can be done simultaneously with just one pair of foot pedals 20. The driver 21 then has his hands free to direct the flexible intake tube 5 between, for example, a parked car and a pavement curb 22.

A stationary intake slope runs diagonally across its entire width beneath the car. This suction slope is preferably provided with a horizontal roller 24 having a horizontal brush (not shown) mounted obliquely.

The following examples illustrate several embodiments of mobile vacuum cleaners according to the invention. Example] and Example 2 relate to the committee's public road vacuum cleaner.

EXAMPLE 1 FIG. 6 shows a suction type urban vacuum cleaner according to the invention for cleaning the streets of a subcommittee, designated in its entirety by the reference numeral 18. This includes the previously mentioned suction and cleaning cyclone device, which is mounted on a free-suspended hydraulic self-propelled vehicle and its guide equipment. Each settling chamber 2 connected to at least one cyclone 3 is arranged behind the driver's seat 27 together with a suction turbine 25 and one drive motor 26 . The flexible suction pipe 5, which is arranged to rotate about a vertical axis, is controlled manually by a driver 21, for example.

The lower body 11 of the settling chamber 2 and each cyclone 3 consists of a removable cylindrical frame 29.

Each of these bodies is covered with a garbage bag 6 for collecting and holding garbage. The garbage bag 6 is held open in position, regardless of suction, by a frame 29 consisting of a series of vertical L-shaped rods arranged like a cylinder generator. The rod is fixed at the top with a flat ring so that the bottom is free.

The garbage bags located around the cylinder are attached with fastening tape 30. To remove debris from the hopper, the operator shuts off the suction tube, removes the stopper tape 30, and rotates the cylinder toward him. Then, to attach the lid, raise the cylinder using the support slide rod. Then he can use paper, animal feces, beach gravel, sand, etc.
The garbage bag 6 containing debris consisting of fallen leaves and other moist debris can be removed. The amount of garbage collected depends on how it accumulates. Bags full of garbage are taken out of vacuum cleaners, tied up with string, and loaded on the side of the road or into a transport vehicle.

The inside of the body, including the L-shaped rod, is cleaned by a flexible suction tube before being inserted into a new bag 6.

The vacuum cleaner is equipped with a device for collecting animal feces with a rotating brush in its front part.

This device can be controlled remotely from the driver's cab. Most animal feces can be removed by sucking, but the waste can be removed by brushing.

Example 2 This mechanical separation device is mounted on a self-propelled vehicle that is manually steered using an operating handle 31. A suction port 4 for cleaning roadside and pavement curbs is provided on the side. This suction port 4 is supported by a flexible tube 5 (Figs. 3 to 5). The present invention is not limited to the embodiment described above merely as an example, and various modifications can be made to the embodiment. are possible without departing from the scope of the invention.

The suction device may therefore have a radiator 32 which uses compressed air 33 coming from a compressor, not shown. The radiant air is directed into a cyclone where it releases dust.
