Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sealing structure for separating and discharging solids conveyed by air pressure,

The present invention relates to a sealing structure of an apparatus for separating and discharging solids conveyed by air pressure.

Some of the fields that carry solids by pneumatics include dust collectors, vacuum cleaners, grain conveying systems, and devices for collecting positive or negative pressure particles that are derived during grinding or cutting.

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.

A solution for solving such a problem is disclosed in Korean Patent Laid-Open No. 10-2015-0033591 filed by the present invention.

An apparatus for separating and discharging solids conveyed by the above-described pneumatic pressure comprises a plurality of chambers provided in a collecting chamber in a main body, a filter provided in each of the plurality of chambers, A flow port through which the air from which the solids are removed by the filter flows, and a discharge port through which the solids filtered by the filter are discharged to the outside of the chamber are all provided on the bottom of the collecting chamber.

Particularly, the plurality of chambers are partitioned by a bottom surface of a tubular portion with an upper end closed and a bottom surface of a plurality of partition walls fixedly inscribed on the tubular portion airtightly contact with the bottom of the trapping chamber.

The seal of the elastic material is interposed between the bottom surface of the tubular portion and the bottom surface of the plurality of partition walls to hermetically contact the bottom of the collection chamber.

However, since the lower surface of the tubular portion extending in the circumferential direction and the bottom surface of the plurality of partition walls extending in the radial direction are provided on the bottom of the collecting chamber with the seal interposed therebetween so that the seal is rotated and hermetically and elastically The contact with the bottom is not possible because the seal can not be pressed and rotated with the same amount of deformation in the direction of the axis of rotation of the tubular portion in the circumferential and radial directions of the tubular portion, It is theoretically possible and practically impossible that the contact portions of the bottom of the collection chamber with respect to the partition wall portion are made of a nonporous one another.

The present invention has a problem in solving the above-mentioned problems.

The present invention is characterized in that a base end is provided on the bottom surface of the tubular portion and the bottom surface of the plurality of partition walls and a portion having a base end and a back end on the bottom surface of the tubular portion are inserted into a ring- So that the above-mentioned problems can be solved by bringing the portion where the base ends and the tip end of the back end hermetically contact with the bottom of the collecting chamber in the airtight sliding contact with the bottom surface of the partition walls.

According to the present invention, the bottom surface of a plurality of partition walls extending in the radial direction from the bottom surface of the tubular portion extending in the circumferential direction is reliably and hermetically and elastically contacted with the bottom of the collection chamber , The plurality of chambers are securely and hermetically partitioned with respect to each other such that solids conveyed by pneumatic pressure are reliably separated from the air in the chamber and discharged out of the chamber, It is possible to make the interposed filter cleaned.

1 is a perspective view showing an embodiment according to the present invention,
2 is a sectional view of Fig. 1;

Hereinafter, a sealing structure of a device for separating and discharging solids conveyed by pneumatic pressure in the embodiment according to the present invention will be described in detail with reference to Figs. 1 and 2. Fig.
