Abstract

The invention discloses a distant filter device; the distant filter device comprises a cabinet body (4), a drive mechanism, a lifting mechanism and a filter mechanism; the drive mechanism comprises a drive motor (2); the drive motor (2) is connected with a nut (3) by a lead screw (7); the nut (3) is connected with the lifting mechanism; the lifting mechanism is arranged below the upper end face of the cabinet body (4); the filter mechanism is arranged below the lower end face of the cabinet body (4); the filter mechanism comprises a filter cup (9) and a filter tube (10) which is inserted in the filter cup (9); the filter cup (9) is installed on the base of the lifting mechanism; the filter tube (10) is connected on the lower end face of the cabinet body (4); the filter cup (9) is communicated with a feeder (1); the filter tube (10) is communicated with a draw off nozzle; the inner side at the upper portion of the filter cup (10) is provided with a scraper (11). The device is able to achieve the distant replacement operation of the filter tube, so as to prevent the operating staff from directly contacting poisonous substances, thereby increasing the safety of the operation.

Description

technical field [0001] The invention relates to the field of filtering devices, in particular to a remote filtering device capable of realizing batch processing of radioactive substances, which is mainly used in radioactive environments. Background technique [0002] The invention is proposed aiming at filtering and separating toxic suspension liquid in a radioactive environment. In previous projects, the filtration of radioactive substances was carried out using very simple devices such as figure 1 As shown, the filter cloth 20 is clamped with a clamp 19 on the filter bucket 18, and a vacuum pipeline 21 is connected below the filter bucket 18, and the filtered filter cake is on the top of the filter cloth 20, and can be reused The operating tool sweeps the filter cake into the cup. All operations are carried out in the glove box, and the operation is open. It is easy to spill the filter cake into the glove box, causing a nuclear accident. High level requirements. Conten...
