Elastic cathode ring for electroosmosis dehydrator

Abstract

The invention provides an elastic cathode ring for an electroosmosis dehydrator. The elastic cathode ring comprises current-conducting plates, bases, hinge pull rods and return springs, wherein the bases are fixedly arranged on an end plate of a roller, and the current-conducting plates are circularly and uniformly distributed on the circumference of the base; each of the current-conducting plates consists of an inner arc side, an outer arc side and an arc top and the cross section of each current-conducting plate is n-shaped, and the edge of the arc side is adaptive to the external circle of a roller; each of the hinge pull rods passes through the roller and each base and is fixedly connected with each current-conducting plate, and a gap is reserved between each base and the inner arc side on the inner side; the return springs are arranged between the arc top and the corresponding base. When a filter screen looses or partially looses, the roller and the filter screen are matched in a non-tight manner and the return springs rebound, and the elastic cathode rings and the cathode filter screen are further in a communicated state, so that the heating and igniting phenomena caused by poor partial contact of the cathodes are reduced, a filter cake can be further compacted, the dehydrating effect is remarkably improved, and the reliability of equipment is remarkably improved.

Description

technical field [0001] The invention relates to an electroosmotic dehydrator, in particular to a drum type electroosmotic dehydrator. Background technique [0002] In general, an electroosmotic dehydrator is a device equipped with a direct current supply to form an electric field and remove water combined with sludge through electrophoretic properties, and it can dehydrate the sludge contained in the sludge through a voltage difference. moisture. [0003] rollers (also known as drums) which are fitted in large numbers with + or / and -; chain rails which are mounted separated from the roller space by a constant distance and fitted with + or / and -; and filter cloth belts, It is wound between the drum and the chain track for the transfer and dewatering of sludge. [0004] In the electroosmotic sludge treatment equipment, it is necessary to set up a positive drum and a filter screen, and the cooperation of the two can realize the dehydration of the sludge. In the existing slud...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to reduce the phenomenon of heating and sparking caused by local poor contact of the electrodes due to the loose fit between the drum and the filter screen.
