Electrode type sludge pressing belt

Abstract

The present invention discloses an electrode type sludge pressing belt. The pressing belt is divided into an upper pressing belt and a lower pressing belt according to a filtering belt, wherein the upper pressing belt and the lower pressing belt are annular belts with track structures. An electrode strip on the upper pressing belt is connected with a vertical slide line, and the lower pressing belt is connected with flat slide lines, wherein the two flat slide lines respectively and elastically contact a positive electrode and a negative electrode of a preset 24-120 V direct current power supply. During using the pressing belt of the present invention, the upper pressing belt and the lower pressing belt synchronously perform uniform winding movements, obtain electricity after entering the pressing region, and relatively clamp the filtering belt carrying wet sludge, electrophoresis of the wet sludge is generated under a potential difference condition, and cell water in the wet sludge overflows after wall breaking, and flows toward a lower bridge plate with a negative potential, such that the wet sludge pressing and dewatering efficiency is substantially improved under the combination of the electrophoresis condition and the pressing condition.

Description

Technical field [0001] The present invention relates to an environmental protection equipment accessory. Specifically, the present invention relates to a press belt supporting a sludge dewatering machine. Background technique [0002] Belt sludge squeezing dehydrator is a special equipment that uses squeezing belts and rollers to repeatedly wind and press to separate sludge and water. The wet sludge is viscous, and the cell water in it remains in the sludge particles. Because of the high surface tension of the cell water, it is not easy to break and seep out under normal pressure. In the prior art, in order to increase the dehydration efficiency of the sludge dewatering machine and improve the index of the sludge biscuit degree, electrophoresis technology is used in the sludge dewatering machine to help cell water break the wall. The specific method is to connect the pressing belt to the negative electrode of direct current, and the matched roller to connect to the positive elec...

AI Technical Summary

Problems solved by technology

One is that most of the outer surface of the anode roller is wrapped by the press belt when the anode roller is running, the heat generated during the electrophoresis process is not easy to dissipate, and it is easy to deteriorate the working condition of the roller; secondly, under certain temperature and humidity conditions, the surface of the roller is easy to generate electricity Chemical corrosion; another one is that the press belt in the prior art is a steel mesh structure, and there is a potential difference between the press belt and the roller shaft during the pressing process, which is prone to tip discharge problems, which are frequently generated in the sludge dewatering machine. There are also potential safety hazards due to electrical corrosion damage on the surface

Due to the existence of the above problems, a series of problems such as high failure rate and high operating cost of the existing technology are caused.
