Description

Technical Field

[0001] The utility model relates to the field of sludge filter pressing, in particular to a sludge disposal filter pressing device. Background Art

[0002] A filter press is a mechanical device that uses a filter medium to apply a certain pressure to an object and cause the liquid to seep out. The filter press injects the filter material into the filter chamber through the pressure of the feed pump. The filter material enters the filter plate from the feed hole on the end face of the thrust plate, and then is distributed to all the filter chambers through the center hole of the filter plate. After the solid and liquid are separated by the filter medium in the filter chamber, the filtering purpose is achieved.

During use, the traditional sludge disposal filter press device cannot allow the mesh conveyor belt to transport the sludge while washing the filter cotton filled inside it. The filter cotton is prone to clogging after long-term use, which affects the effect of sludge filter pressing, reduces the filter pressing efficiency of the filter press device for sludge, and increases the labor intensity of operators when maintaining the filter press device. Moreover, it is impossible to automatically discharge a large part of the water absorbed by the filter cotton while automatically cleaning the sludge attached to the surface of the mesh conveyor belt. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content

During the sludge transportation process, the filter press roller 12 squeezes the sludge to filter water. During this process, the driving motor 22 drives the cleaning brush roller 2 to rotate, and the cleaning brush roller 2 drives the chain 16 to rotate through the second sprocket 21, and then the chain 16 drives the filter press roller 12 to rotate through the first sprocket 15, so as to realize continuous sludge filtering;

[0024] It is worth noting that see Figure 1 and Figure 2The second sprocket 21 is fixedly connected to one end of the cleaning brush roller 2, and the other end of the cleaning brush roller 2 is fixedly connected to the output end of the driving motor 22. Flushing pipes 23 are installed on both sides of the cleaning brush roller 2. One end of the flushing pipe 23 is connected to a booster pump 25 through a water pipe 24, and the other end of the booster pump 25 is connected to a water tank 26 through a pipeline. One end of the flushing pipe 23 is fixedly connected to the bottom of the sludge conveying mechanism 1, and its spraying part faces the position where the cleaning brush roller 2 contacts the mesh conveyor belt 34. One end of the water pipe 24 is sealed and connected to one end of the flushing pipe 23, and the other end of the water pipe 24 is sealed and connected to one end of the booster pump 25.
