Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an internal dust collector having an air induction plate,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector, and more particularly, to an internal dust collector having an air induction plate for uniformly filtering dust air to a plurality of bag filters.

Generally, a dust collector is installed in a workplace where dust is generated, and dust and dust contained in the air are collected to collect dust and dust, and then clean air is discharged to the outside to improve the working environment.

The dust collector used for such a purpose allows dust or dust of the dust air to pass through the surface of the bag filter so that dust or dust contained in the dust air can be filtered.

To explain this again, the prior art filters out dust or dust contained in the compressed air on the vertically installed bag filter surface, and opens the upper surface of the filter to discharge clean air upward. In this prior art, dust or dust having a light specific gravity or a strong adsorbability among the dust or dust attached to the surface of the bag filter is stuck to the bottom without falling down even if the filter is shaken by high-pressure air, leading to premature clogging of the bag filter.

Also, since the number of bag filters installed between the inlet and outlet of the housing varies depending on the mounting position, the amount of filtering operation is different for each bag filter.

In other words, the bag filter at a specific position filters a large amount of compressed air due to a large amount of contact with the compressed air, and the bag filter at another position filters a small amount of compressed air with a low contact with the compressed air. do.

As a result, the lifetime of each bag filter in the same dust collector becomes different, which causes troubles in maintenance and maintenance, and also lowers filtering efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of an internal collecting dust collector having an air induction plate according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an internal collecting type dust collector provided with an air induction plate according to the present invention, and FIGS. 2 and 3 are views showing the inside of an internal collecting type dust collector provided with an air induction plate according to the present invention.

FIG. 4 is a cross-sectional view of an internal collector type dust collector provided with an air induction plate according to the present invention.

The inner collecting type dust collector having the air induction plate according to the present invention includes a housing 10, a fixing plate 20 installed inside the housing 10, and a plurality of bag filters Bag A filter 30, and an air induction plate 40 installed on the fixing plate 20.

The housing 10 is provided with an inlet 11 at one side thereof and a discharge port 12 at the other side thereof and a dust box 13 for storing dust at the bottom thereof.

The inlet 11 is provided on the upper side of the housing 10 so that dust air containing dust can be introduced into the housing 10 at a high speed through the inlet 11.

The outlet 12 is provided on the upper side of the housing 10 and more particularly on the opposite side of the inlet 11 and is connected to a clean The air is discharged to the outside.

The dust box 13 is installed at the lower end of the housing 10 to collect dust falling to the lower end.

More specifically, an air jet nozzle 14 for jetting air at a high pressure is provided in the housing 10 to remove dust from the bag filter 30.

When high-pressure air is blown strongly from the air injection nozzle 14 toward the inside of the bag filter 30, the dust collected inside the bag filter 30 is separated from the bag filter 30, So that the falling dust collects in the dust chamber 13.

The fixing plate 20 is installed inside the housing 10, more specifically, immediately below the inlet 11, and the fixing plate 20 has through holes 21 formed at regular intervals.

The bag filter 30 is installed vertically in the housing 10. The bag filter 30 is an internal collecting type filter, and the upper end portion thereof is fitted into the through hole 21 of the fixed plate 20. When the compressed air enters the housing 10 through the inlet 11, the compressed air moves from the upper side of the fixed plate 20 to the inner space of the bag filter 30, And the clean air from which dust has been removed passes through the bag filter 30 from the inside to the outside.

A plurality of air induction plates (40) are provided on the upper surface of the fixing plate (20). The air induction plate 40 serves to allow the compressed air introduced through the inlet 11 to enter downward into the bag filter 30.

More specifically, the air induction plate 40 is composed of a vertical plate 41 and a swash plate 42 formed integrally with the vertical plate 41.

The lower end of the vertical plate 41 is connected to the fixing plate 20 and is installed upright on the upper surface of the fixing plate 20.

The swash plate 42 is formed to be inclined from the upper end of the vertical plate 41 toward the inlet 11. The tilt angle is bent to a degree not to exceed 90 degrees.

The height of the air induction plate 40 according to the present invention is increased from the inlet 11 side toward the outlet 12 side. The height of the vertical plate 41 of the air induction plate 40 is increased from the inlet 11 toward the outlet 12 so that the height of the air induction plate 40 as a whole becomes higher than the height of the outlet 12, The higher the value, the higher the level.

The reason why the air induction plate 40 is structured in this way is to allow a plurality of bag filters 30 installed inside the housing 10 to perform a filtering operation uniformly by efficiently distributing the compressed air.

The compressed air introduced into the housing 10 through the inlet port 11 moves at a high speed toward the outlet port 12 of the housing 10 because the compressed air flows into the housing 10 at a considerably high speed, The bag filter 30 located close to the inlet 11 does not cause much contact with the compressed air and conversely the bag filter 30 located far from the inlet 11 has a large amount of contact with the compressed air It happens.

Therefore, the bag filter 30 located near the inlet 11 does not perform much filtering operation, and the bag filter 30 located far from the inlet 11 relatively performs the filtering operation on the compressed air. do. That is, a load is slightly applied to the bag filter 30 located near the inlet 11, and a large load is applied to the bag filter 30 located far from the inlet 11.

In order to prevent the bag filter 30 located at a specific position from being subjected to too much filtering operation to be subjected to a heavy load and to allow all the bag filters 30 installed in the housing 10 to perform filtering uniformly, In the invention, the air induction plate 40 is provided.

In order to perform uniform filtering, uniform airflow from the bag filter 30 located near the inlet 11 to the bag filter 30 located far from the bag filter 30 should be guided into the bag filter 30. For this purpose, The height of the air induction plate 40 is higher as the distance from the inlet 11 is higher.

Dust and dust are collected on the inner surface of the bag filter 30 while being supplied from the upper side of the bag filter 30 to the lower side of the bag filter 30 by the air induction plate 40 configured as described above. Since the flow of the compressed air is directed from the upper side to the lower side and the high-pressure air injected from the air injection nozzle 14 flows from the upper side to the lower side as described above, the air blown from the air injection nozzle 14 at a high pressure It is possible to smoothly remove the dust from the dust.

The internal dust collector having the air induction plate according to the present invention is configured such that dust air is introduced into the housing 10 through the inlet 11 in order to reduce the load of the bag filter 30 installed in the housing 10 It is also possible to remove the considerable amount of dust contained in the compressed air before the bag filter 30 performs the filtering by passing the cyclone 50 first.
