Quick-mounting-type activated carbon filter

Abstract

The invention provides a quick-mounting-type activated carbon filter. Two support square frames are arranged in a cylinder body; the periphery of each support square frame abuts against and is fixed to the inner wall of the cylinder body; one side wall of each support square frame is provided with a square opening; the cylinder body is provided with through holes communicating with the square openings; each carbon plate has a square shape and penetrates through the corresponding through hole and enters the corresponding square opening; the three side surfaces of each carbon plate abut againstthe inner wall of the corresponding support square frame; the outer end of each carbon plate is connected with a cover plate which is used for closing the corresponding through hole, and the inner side of each cover plate abuts against the outer surface of the cylinder body; the inner wall of each support square frame is rotationally connected with a sealing door; and the rotating shaft of each sealing door is provided with a torsion spring which drives the sealing door to completely close the corresponding square opening. The cylinder body of the activated carbon filter is provided with the through holes, the carbon plates can be pulled out from the through holes for replacing activated carbon particles at the internal part, and when the activated carbon filter needs to be overhauled, theinternal part can be observed from the through holes. According to the activated carbon filter, the replacement of the activated carbon particles is convenient and the maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of liquid ammonia filters, in particular to a quick-loading activated carbon filter. Background technique [0002] Liquid ammonia is a special product, which is a liquid state of ammonia gas under high pressure and low temperature. Ammonia is an important chemical raw material. For the convenience of transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. Liquid ammonia is widely used in industry, is corrosive and easy to volatilize, so its chemical accident rate is very high, but there is no good liquid ammonia storage device at present. [0003] High-purity ammonia gas is a special gas used as a nitride film forming gas in the manufacturing process of liquid crystal display (LCD display) and compound semiconductor (LED). LEDs are used for general lighting and background lights of liquid crystal displays. In addition to general lighting, the market for LEDs f...

Problems solved by technology

[0004] In the prior art, the carbon plate inside the activated carbon filter is mostly fixed, and it is troublesome to replace it. When the existing activated carbon filter is overhauled, the entire filter body needs to be disassembled, which is inconvenient for maintenance.
