Description

Booth Type Dust Collector

The present invention relates to a booth type dust collector, and more particularly, to a booth type dust collector capable of collecting dust more efficiently by changing the shape and arrangement of a filter installed in a work booth.

In general, the dust collector (集塵 器) removes various pollutants such as harmful gases, dust, bacteria, fungi and viruses contained in the air, and performs a function to maintain a user's active space comfortably.

As the industrial economy develops, the workplaces that perform various processing and manufacturing processes generate various harmful gases or dusts that are harmful to the human body, adversely affecting the working environment and physical health of workers and producing precise products. In the case of occupations, as the defective rate of the products produced increased, economic losses resulted from the decrease in productivity.

Therefore, at present, various dust collectors for dust collecting hazardous gases or dusts have been developed and used in industrial sites.

On the other hand, the dust collector is largely divided into two types, dry and wet, dry again is divided into electric dust collection and filter filtration type.

First, the wet dust collector is a method of purifying by infiltrating or dissolving contaminants such as dust and gas by bringing inhaled air into a wet purifier such as water.

In addition, the electrostatic precipitating method is a method in which an electric field generated by electric force collects contaminants moving to the collecting pole.

In addition, the filter filtration type is mainly used in a work site that performs a processing process and a manufacturing process, and collects dust and dust in the process of flowing air between the filters.

A dust collecting chamber is installed around the filter filtration dust collector to prevent the dust generated during the processing of the article from spreading to the outside.

However, since the dust collecting chamber installed around the conventional dust collector has to be prepared separately, there is a problem in that the installation cost is additionally generated.

In order to solve the above problems, the applicant has disclosed a "boot-type dust collector" through the Republic of Korea Patent Registration No. 10-0484266 (hereinafter referred to as "prior art") and describes the schematic configuration It is as follows.

 As shown in FIG. 1, a booth type dust collector according to the related art is connected between a main body 10 having a dust inlet 15 and an air outlet 18, and between the dust inlet 15 and an air outlet 18. An exhaust fan 25, a filter 30 provided at the front end of the exhaust fan 25 to filter dust in the air discharged to the outside, and between the exhaust fan 25 and the filter 30. And an air spray nozzle (35) configured to reversely spray air toward the filter (30) to remove dust adhering to the filter (30), wherein an opening (23) is formed in front of the main body. The work booth 20 integrally formed at the front end of the dust inlet 15 of the 10 and the air supply passage 55 provided to communicate with the opening 23 of the work booth 20 from the rear end of the exhaust fan 25. ) And the dust of the work booth 20 is introduced into the main body 10 through the dust inlet 15 and the air is discharged. The air discharged to the sphere 18 is supplied around the opening 23 of the work booth 20 through the air supply path 55 to form an air curtain in the opening 23.

Therefore, the worker can easily perform the work while going out and of course, since a separate dust collecting chamber for collecting dust is not required, it is possible to reduce costs such as facility costs.

However, the booth type dust collector according to the prior art has a structure in which a plurality of filters are installed along the longitudinal direction and the transverse direction with respect to the entire installation surface in order to increase the dust collection efficiency, and have a structure having a predetermined interval in the longitudinal and transverse directions therebetween. Therefore, there was a limit to greatly improving the collection efficiency.

Furthermore, since the plurality of filters have a circular shape and are vertically installed with the ends of the open inlet facing downwards, the plurality of filters have a structure that intersects with the dust inlet, so that the air flowing from the dust inlet receives the open end of the filter. The flow of diesel oil flowed through at a very low rate, and the capturing ability of fine dust was low.

In addition, as illustrated in FIG. 1, the filter installed at the dust inlet side and the filter installed at the inner wall side of the main body have a problem in that the efficiency of the entire dust collector is lowered due to different collection efficiency.

That is, according to the prior art, the filter installed on the dust inlet side is concentrated on the outer periphery of the dust collection, whereas in the case of the filter installed on the opposite side, the dust that does not pass through the dust inlet side filter is the inner wall surface of the main body. As it is collected after hitting a number of times, even if the filter having the same performance, there was a problem that is used inefficiently depending on the position of the arrangement.

The present invention has been made to solve the above problems, the object of the invention is to change the shape and installation structure of the filter to increase the collection area and reduce the flow resistance to increase the dust collection efficiency for dust significantly It is to provide a type dust collector.

In addition, another object of the present invention to provide a booth dust collector that can arbitrarily adjust the suction force of the air flowing into the dust collector according to the amount of dust generated.

It is characterized in that the inflow of the air is controlled in accordance with the dust inlet or in communication with the deviation.

According to the present invention having the above-described configuration, as the hollow of the filter installed in the dust collecting chamber is formed in a rectangular shape, the entire longitudinal direction of the filter is collected in either the longitudinal direction or the transverse direction with respect to the installation surface. Since it can be utilized as the area, there is an effect that can greatly improve the dust collection capacity for collecting dust.

In particular, the hollow inlet of the filter is disposed in a direction opposite to the dust inlet, so that the dust flowing in with the air can naturally move along the length of the filter, thereby reducing the resistance of the flow path and improving the filtering time, thereby resulting in fine The collection of dust is also smooth.

In addition, since the filter is installed on the same line as the dust inlet, the filtering action is not concentrated only on any one filter, and the entire filter may be uniformly performed, thereby improving reliability.

In addition, by installing a slide door in the dust inlet, it is possible to organically control the inflow of air from the maximum to the minimum according to the amount of dust generated in the work booth.
