Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a high-pressure transport apparatus for pneumatically transporting various granular materials at a high pressure.

[Conventional technology]

2. Description of the Related Art A conventional high-pressure transport apparatus is disclosed in, for example, JP-A-63-31939, by applying a high pressure to a container (also referred to as a pressurized tank or a blow pot) containing powder and granular material. Is transported to the transport pipe side for transport.

FIG. 4 is a configuration diagram illustrating the structure of the above-described conventional high-pressure transport device, in which the powder X contained in the supply hopper B passes through two input valves C and D provided at the discharge ports. It is supplied into the container A, and when it reaches a certain amount, the input valves C and D are closed,
Activate the compressor (not shown) to operate the main pipe G
From the blow pipes Ga, Gb, and Gc, compressor air is supplied to the container A and the inlet of the transport pipe E, and the transport pipe E.
Are supplied to the air knives F provided in the middle of the process, and the powder X is intermittently transported by the plug.

When the amount of the granular material X in the container A is reduced due to the progress of the transportation described above, the supply of the compressor air is stopped, and then the supply valves C and D are opened to supply the granular material X from the supply hopper B. And the above-described transport is repeated again.

Therefore, in the above-mentioned conventional high-pressure transport device, the additional supply of the granular material X cannot be performed during transport, and the transport needs to be completely stopped when supplying (input) the granular material X. There is a problem that the transport volume is reduced due to the batch transport. Therefore, conventionally, the decrease in the transport volume was compensated by increasing the transport capacity of the transport device to about 1.5 times the required transport capacity.

[Problems to be solved by the invention]

However, increasing the above-mentioned transport capacity by 1.5 times would require a corresponding increase in the size of the transport pipe E and / or the capacity of the compressor. In addition, there is a problem that the product life of the container A or the transport pipe E is shortened, and the supply hopper B is used in order to use the large container A and prevent the backflow of the granular material X. Since the two input valves C and D need to be connected between them, the L dimension shown in FIG. 4 is inevitably increased, so that it cannot be used indoors where a sufficient height cannot be obtained, or the entire apparatus becomes expensive. Therefore, there is a problem that the cost of the auxiliary equipment such as the supply hopper B is increased, which affects the price of the entire transport apparatus.

Therefore, a technical problem of the present invention is that the transportation of the powder and the granular material is not a batch transportation but a continuous transportation method, and a sufficient transportation result can be obtained with a normal transportation capacity. It is to provide a continuous high-pressure transport device that can be used.

[Means for solving the problem]

Means taken in the present invention to solve the above technical problems are as follows.

In a high-pressure transport device configured to transport a granular material charged into a container at a high pressure to a transport pipe side by pressurized gas supplied into the container, (1) a rotary disk configured to be rotatable; A plurality of the above-mentioned containers are mounted on each of the containers, and an input port for the powdery material is provided on the upper surface of each of these containers, and a pinch valve having a connection port is provided on the bottom discharge port.

(2) A pinch valve having a fitting port is attached to the inlet side of the transport pipe, and the fitting port is configured to be freely connectable to a connection port of a container set at a transport position according to rotation.

(3) On the upper surface side of each of the containers, a supply port for supplying the granular material toward the input port of the container set at the supply position according to the rotation, and an input port of the container set at the transport position are closed. And providing a lid with a blow pipe for supplying a pressurized gas into the container.

(4) An operating arm for connecting by operating the insertion port on the transport pipe side toward the connection port of the container, and an operating arm for operating and closing the cover with the blow pipe toward the input port of the container. Connect each tip to the same air cylinder so that the above connection and closure can be made together.

However, in this case, the pinch valve means that the valve body closes the valve path to prevent the discharge of the granular material at normal times when the valve body is not subjected to pressurization. Open means to open the valve path and allow the transportation of the granular material.

[Action]

 The above means works as follows.

The element of the above (1) enables the continuous transportation of the granular material by filling the granular material in each of the plurality of containers and sequentially using the granular material, and is supplied from each charging port. The powder is prevented from being discharged by the pinch valve, and can be maintained in a filled state until the turn comes.

The element (2) is a safe transportation method in which when the insertion port on the transportation pipe side is connected to the connection port on the container side, a pinch valve that can prevent leakage and backflow of the granular material is attached to both sides of the connection part. A path can be formed.

With respect to the container set in the supply position according to the rotation of the turntable, the element (3) can supply the granular material through the supply port and the charging port, and is also set in the transport position according to the rotation of the turntable. For other containers, pressurized gas (compressor air) is supplied from the blowpipe with the input port closed by the lid, and the powder in the container is transported by opening each pinch valve. It can be transported under high pressure to the pipe side. Therefore, the powder can be continuously transported by supplying and transporting the powder at a constant rotation for each container.

In the element (4), the closing of the charging port by the lid plate and the connection of the insertion port on the transport pipe side to the connection on the container side can be performed together by one air cylinder. In addition to simplifying the mechanism, it is possible to easily set the synchronization between the closing timing of the insertion port and the insertion port timing.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
