Description

[0001] The present invention relates to a device for separating and discharging solids conveyed by pneumatic pressure from air,

The present invention relates to an apparatus for separating and discharging solids conveyed by air pressure from air.

Sectors that carry solids by pneumatics include dust collectors, vacuum cleaners, grain conveying systems, and equipment that collects particles that are derived during grinding or cutting by negative pressure.

In order to collect solids transported by air pressure, there are a filter type and a cyclone type for separating air and solids, but all of these types have a problem that the solids collected in the chamber must be manually discharged out of the chamber.

The reason why the solids are manually discharged out of the chamber is that when the apparatus for conveying the solids by the pneumatic pressure is used for a certain period of time, the solids are accumulated in the chamber, and the vacuum is not properly formed in the chamber. In this case, the user manually pulls the solids accumulated in the dust chamber out of the main body.

Such a process of discharging solids causes a problem that the user touches the abominable object with his hand and is treated as a very inconvenient and troublesome work.

In order to solve such a problem, a vacuum cleaner, which is a device for conveying solids by pneumatic pressure, is disclosed in Patent Registration No. 10-1372513, which is patented and patent registered by the present inventor.

In the vacuum cleaner described above, the dust outside the cleaner main body can be received in the cleaner main body by the negative pressure and can be discharged outside the cleaner main body by the positive pressure, so that the dust, However, the rotary valve is arranged below the dust collecting chamber and the dust collecting chamber, which causes the vacuum cleaner main body to be excessively large in the height direction of the main body.

A vacuum cleaner for solving such a problem is disclosed in the pending Patent Publication No. 10-2014-0097071.

The vacuum cleaner includes a plurality of pockets for rotating the dust collecting chamber and allowing one of the plurality of pockets to flow into the suction port and the suction chamber at the same time, A plurality of partition walls for partitioning the plurality of pockets are rotated while rubbing the filter or the perforated plate on one side thereof to remove the solid or sticking to the filter or perforated plate, One of the pockets circulates the solids discharge tube that discharges the solids out to the pockets which do not flow into the suction port and the suction chamber, and the solids accumulated in the dust collecting chamber are discharged through the vacuum cleaner Without the rotary valve being an air-tight opening / closing means interposed in the solids discharge pipe, Hayeoseo body to be accommodated in the collecting bag placed outside, the user can, while the aversion to clean water in which exclusion conditions as to touch by hand the accumulated solids on the filter exhaust collecting chamber out of the body.

However, the vacuum cleaner described above has a problem in that a manufacturing cost is increased due to a complicated structure for rubbing a filter or a perforated plate while one side of the plurality of partition walls is rotated.

A vacuum cleaner for solving such problems is disclosed in pending patent application No. 10-2014-96148.
