Description

Suction and discharge structure of industrial dust collector {Dust collector for workshop}

The present invention relates to a dust collecting device having an improved suction and discharge structure that solves the problem of exhaustion and obstruction in an environment in which the degree is heavy and a large amount of scattered dust or scattered particles are generated.

When a vehicle is shipped from a finished vehicle factory or a maintenance factory, generally, it is painted to protect the body from external contaminants.This painting may cause many scratches or discolor as the vehicle is exposed to the outside for a long period of time. The original painting is removed at a maintenance shop, etc., and then repainted.

In this way, to remove the paint of the vehicle, a tool such as a hand grinder is used to remove the paint of the vehicle. In this process, a lot of dust is generated and spreads to the surroundings. As described above, dust scattered around the surrounding air may pollute the surrounding air and cause various respiratory diseases, and therefore, installation of a clean room to prevent the spread of dust in the workplace is required.

In addition, in various painting facilities, fine dust and dust generated in the process of using a grinder, sanding machine, spray gun, etc., are suspended in the air and may enter the worker's respiratory tract, thereby causing various respiratory diseases and at the same time fine dust. There is a problem of polluting the atmosphere by being discharged to the outside.

In such a clean room, a dust collector is installed to collect dust contained in the air by vacuum suction of the internal air, and to discharge clean air from which the dust has been removed to the outside. As a conventional technology of such a dust collector, the dust removing apparatus for automobile painting disclosed in Korean Patent Publication No. 2004-0084307 may be exemplified, and the dust removing apparatus disclosed in this patent document sucks air in a clean room to collect dust in the air. It is configured to be filtered through a plurality of filters installed in the.

Recently, fine dust and dust generated in industrial sites are immediately aspirated at the site using a dust collector or a vacuum cleaner and collected separately from the air to keep the air clean. However, in conventional industrial vacuum cleaners, filters are easily blocked due to a large amount of fine dust generated in the industrial field, and as a result, the ability to remove fine dust and dust easily deteriorates, and the operator has to frequently clean or replace the filter. There is a hassle. Accordingly, there is a need for development of an industrial vacuum cleaner (dust collector) that can effectively remove dust in the air that is sucked in in an industrial vacuum cleaner, but can easily clean the collected fine dust and prevent clogging of the filter.

In the case of the prior art, filter clogging occurs frequently, and the dust collected inside the dust collector must be periodically discharged to the outside, and in this process, there is an inconvenience of removing the dust manually after opening the dust collector.
