Antipollution filter box-body with quick clamp shaft

Abstract

The invention provides an anti-pollution filter box body with a fast clamp shaft. Each box body is provided with one or more filter element units inside; the filter element unit is arranged on an operation face of the box body; a mounting hole of each filter element unit is sealed by a box body cover; each box body cover is fixed on the outer shell of the box body by at least four locking elements; a socket wrench is hung on the outer shell of the box body; each socket wrench corresponds to a filter element unit and is welded at the filter element mounting hole on the operation face of the box body; the box body cover is sheathed on the socket; the box body cover is provided with a cover seal ring; the cover seal ring and the socket are sealed in a guillotine-shaped seal manner; each box body cover is fixed on the outer shell of the box body by four locking elements; a foaming PVC gasket is adhered to the contact face of the filter element and the box body; the filter element is arranged on a filter element bracket which is supported by a cam arranged on the fast clamp shaft; and an operating handle is arranged at the end of the fast clamp shaft. The box body has the advantages that sealing effect is good, efficiency of replacing the filter element is high, and the secondary pollution caused by replacing the filter element is reduced.

Description

Technical field: [0001] The invention is used in industrial ventilation systems, especially nuclear island ventilation systems of nuclear power plants, to purify air and radioactive aerosol (radioactive dust) or radioactive iodine in the air when the box is put into operation. Applicable media are air, gas, radioactively polluted air, etc., working pressure ≤ 3000Pa, with nuclear safety function, working temperature between +5 ℃ ~ 200 ℃, the maximum relative humidity is 100%. One or more filter element units are installed in each box. Background technique: [0002] At present, the filter box used in the industrial ventilation system has a large amount of leakage, which cannot effectively filter the air; the filter element used to filter radioactively polluted air cannot be effectively controlled, and it is easy to cause secondary pollution. ; The time to replace the filter element is too long, thus increasing the time for the staff to receive irradiation. Invention conten...
