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.

Embodiment 1

[0026] figure 1 The shown embodiment of the electrode type sludge press belt is divided into an upper press belt and a lower press belt by the flat filter belt 1 as a boundary. The upper press belt is an endless belt with a crawler structure with an amplitude of 2500 mm, which is configured in an electro-osmotic belt sludge dewatering equipment with a daily output of 40-50 tons of sludge cake. In this embodiment, as figure 2 , image 3 with Figure 4 As shown, the upper press belt is composed of five identical and alternately arranged chains 3 as a longitudinal structure, and each wing plate of the five chains 3 is connected with a transverse upper bridge plate 4 respectively. The upper bridge plate 4 of the upper press belt is made of channel steel, and its width is equal to the pitch of the sprocket 3. The upper bridge plate 4 is connected to the wing plate of the chain 3 with the notch side up. Lay the plastic plate 4.1 on the plane, and then insulate and connect the electr...

Embodiment 2

[0028] The electrode-type sludge pressing belt in this embodiment has a smaller specification with an amplitude of 500 mm. It is configured in an electro-osmotic belt-type sludge dewatering equipment with a daily output of 3 to 5 tons of sludge cake. Such as Picture 8 As shown, both the upper press belt and the lower press belt are composed of two identical and alternately arranged chains 3 as the longitudinal structure. Each wing plate of the two chains 3 is connected to the upper bridge plate 4 and the lower bridge plate 6 in the transverse direction. The structure is exactly the same as the first embodiment, only the component size is reduced in proportion, and the application effect is similar to that of the first embodiment.

[0029] In practical application of the present invention, the upper press belt and the lower press belt synchronously wind at a constant speed, enter the upper press belt and the lower press belt in the press area to obtain electricity and relatively ...

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...
