Automatic exhaust gas removing device for attracting paint particles through static electricity to prevent clogging

Abstract

The invention discloses an automatic exhaust gas removing device for attracting paint particles through static electricity to prevent clogging. The automatic exhaust gas removing device structurally comprises an air inlet pipeline, a searching cabinet, a clogging-preventing device, an air outlet pipe, support legs and a sewage discharging port. Through a negative high-voltage piece and conductionwires, a live ring and side wing blocks are charged with negative electricity, and thus oil paint liquid drops in exhaust gas penetrating through a rotational flow cavity and dust are charged with negative electricity; meanwhile, a positive high-voltage piece is electrified, so that a conduction attraction layer is charged with positive electricity, the oil paint liquid drops with large size and negative electricity are attracted to fit the outer surface of an anti-sticking thin film, the situation that the oil paint liquid drops and the dust are mixedly bonded and clog a filtering net is avoided, then electromagnets with the same magnetism are electrified to generate repulsive acting force, under the cooperation of resilience force of elastic ropes and strong springs, fixation blocks andconnecting pieces drive the anti-sticking thin film to be subjected to deformation moving, and the oil paint liquid drops fitting the outer surface of the thin film are helped to gather and drop intoa sewage storage groove; meanwhile, the electromagnets vibrate a rubber pad, and through via holes, the rubber pad promotes the deformation of the anti-sticking thin film, and gathering and dropping of the oil paint liquid drops.

Description

technical field [0001] The invention relates to the field of exhaust gas treatment, more precisely, an automatic exhaust gas removal device that uses electrostatic suction paint particles to prevent clogging. Background technique [0002] In the process of paint production, due to the extrusion and friction heating of paint by mechanical equipment, the smell of paint will be emitted, which will reduce the air quality of the production workshop and cause pollution to the environment. Bed purification, the existing traditional technology is not comprehensive, has the following disadvantages: [0003] Between the paint and the processing machinery, the gas emitted by frictional heating not only contains a large amount of organic gas, but also contains a lot of fine paint droplets. The fine paint particles combine with the dust in the air during the air extraction process to form a strong bond. The paint mud sticks to the surface of the filter screen, blocks the filter screen, ...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an automatic degassing device that utilizes static electricity to absorb paint particles to prevent clogging, so as to solve the problem that the gas emitted by frictional heating between the paint and the processing machinery in the prior art not only contains a large amount of Organic gas, and contains a lot of fine paint droplets, the fine paint particles combine with the dust in the air during the pumping process to form a highly cohesive paint mud, and then stick to the surface of the filter, blocking the filter, reducing the The efficiency of exhaust gas filtration and purification, and its viscosity makes it difficult to clean the filter, which increases the labor intensity of the staff.
