Description

Technical Field

[0001] The utility model belongs to the field of dust removal and relates to a high-efficiency exhaust gas treatment device for a shot blasting machine. Background Art

[0002] During the operation of the shot blasting machine, a large amount of broken shot and workpiece surface debris are generated after the shot blasting hits the workpiece surface. The dust formed by the large amount of broken shot and workpiece surface debris is discharged into the air outside the shot blasting machine. Before the dust-containing gas is discharged into the atmosphere, it needs to be dust-removed to meet the gas emission standards.

[0003] At present, bag dust collectors, gas filters, etc. can be installed on the exhaust pipe of the shot blasting machine. However, with the operation of the bag dust collectors and gas filters, the filter elements need to be cleaned or replaced regularly, the operating costs are high, and the dust removal effect gradually decreases, which may cause gas emissions to fail to meet the requirements. Utility Model Content

[0004] In order to overcome the defects in the above-mentioned related technologies, the utility model proposes a high-efficiency exhaust gas treatment device for shot blasting machines, which can absorb dust in the exhaust gas of the shot blasting machines and improve the exhaust gas emission quality of the shot blasting machines.

[0005] Some embodiments of the present invention provide a highly efficient exhaust gas treatment device for a shot blasting machine, comprising an exhaust pipe, a dust removal processor, and a dust removal bucket. One end of the exhaust pipe is connected to the shot blasting machine. The dust removal processor is connected to the other end of the exhaust pipe. The dust removal bucket is a barrel with an open top, filled with liquid, and the exhaust outlet of the dust removal processor extends into the liquid in the dust removal bucket.

[0006] Preferably, the shot blasting machine exhaust gas efficient treatment device also includes a bucket cover, the bucket cover is fixed to the upper opening of the dust removal bucket, the pipe between the dust removal processor and the air outlet end passes through the bucket cover, and the bucket cover is also provided with a plurality of through holes.

[0007] Preferably, the shot blasting machine exhaust gas efficient treatment device also includes a gas filter plate, the gas filter plate includes a metal filter mesh, multiple gas filter plates are arranged in sequence from bottom to top, and the filter element pore size of the multiple gas filter plates decreases from bottom to top, and the maximum filter element pore size of the gas filter plate is 1 mm.

[0008] Preferably, the gas outlet end of the dust removal processor extends to below the plurality of gas filter plates.

[0009] Preferably, the gas filter plate further comprises a fixing ring, the ring width of which is 1 / 3 to 1 / 2 times the inner diameter of the fixing ring. The shot blasting machine exhaust gas efficient treatment device further comprises a collection trough, which is an annular trough. A collection trough is fixed in the dust removal bucket below each fixing ring, and the orthographic projection of the fixing ring in the horizontal plane overlaps the orthographic projection of the collection trough in the horizontal plane.

[0010] Preferably, the outer wall of the collecting trough fits the inner wall of the dust removal bucket, and the inner wall of the collecting trough is smoothly transitioned and connected.

[0011] The beneficial effects of the present invention are:

[0012] The utility model adopts a dust removal bucket, and the tail gas of the shot blasting machine is introduced into the liquid, so that the particles in the tail gas of the shot blasting machine are mixed with the liquid to produce a dust removal effect on the tail gas of the shot blasting machine.

[0013] In addition, the utility model adopts a gas filter plate, which can disperse the exhaust gas of the shot blasting machine and improve the adsorption effect of the liquid on the exhaust gas of the shot blasting machine.

[0014] The utility model also adopts a collecting trough. The exhaust gas of the shot blasting machine drives the liquid to rise in the middle part below the gas filter plate. When it runs close to the gas filter plate, the liquid diffuses to the surroundings, which can drive the dust in the liquid to form a circulation. In this way, a large amount of dust gathers in the collecting trough, which can reduce the clogging effect of the dust on the gas filter plate and facilitate later cleaning.

[0027] Preferably, the gas outlet end of the dust removal processor extends to below the plurality of gas filter plates 4 .

[0028] Preferably, the gas filter plate 4 further includes a fixing ring 41, the ring width of which is 1 / 3 to 1 / 2 times the inner diameter of the fixing ring 41.

After the gas enters the liquid, it runs upward. At the same time, part of the dust in the exhaust gas of the shot blasting machine is infiltrated by the liquid and retained in the liquid.

[0035] The exhaust gas from the shot blasting machine is broken up when it passes through the gas filter and then re-enters the liquid above the gas filter, which improves the liquid's ability to absorb dust from the exhaust gas. Simultaneously, the gas lifts the liquid from the center. As it approaches the gas filter, water pressure forces some of the liquid to flow into the dust removal bucket 2, simultaneously driving the dust into the bucket 2. Near the dust removal bucket 2, the liquid and dust flow downward and fall into the collection tank 5.
