Technical Field
[0001] The utility model relates to the technical field of filter pressing technology, in particular to a flexible sludge crushing device for a plate and frame filter press. Background Art
[0002] A plate and frame filter press is a machine that uses pressure to squeeze out water from materials. It is widely used in sewage treatment, chemical industry and other fields. It is mainly used for dehydration or other solid-liquid separation work. After the plate and frame filter press has finished working, the liquid in the material is discharged. When the plate and frame filter press is opened again, only the filter cake is left inside. When it is used in sewage treatment and other processes, the filter cake remaining in the machine is sludge. The sludge needs to be broken, dried and other processes before being landfilled, incinerated for power generation and other operations. It can also be used to make building materials.
[0003] After the existing sludge crushing device has crushed the sludge, it usually performs one or more stages of screening to screen out sludge particles of qualified size, which is convenient for mixing with coal powder and other fuels for power generation or preparation of building materials. Sludge particles that do not meet the size standards need to be poured back into the device for crushing by the staff. The operation is cumbersome and energy-intensive. It requires a vibration motor or other actuators to screen the sludge particles, and the staff needs to manually or the feeding device needs to automatically return the unqualified sludge particles to the crushing device. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a flexible sludge crushing device for a plate and frame filter press to solve the technical problems mentioned in the above background technology.

[0006] By adopting the above technical solution, during the crushing process, a crushing roller drives the second gear to rotate, and the second gear engages with the gear ring to drive the push frame to rotate. After the push frame rotates, the unqualified particles blocked by the filter are pushed back to the top of the crushing roller, and the unqualified particles fall between the two crushing rollers through gravity and are crushed again. The push frame also cleans the filter, effectively reducing the occurrence of filter blockage.

After the motor starts, the output end drives a crushing roller to rotate, and then the two crushing rollers rotate in opposite directions through the meshing transmission of the two first gears. Then the staff manually or through the feeding device feeds the flexible sludge into the feed port, so that the flexible sludge passes through the feed port and falls between the two crushing rollers to be crushed. The crushed flexible sludge falls on the filter screen, and the sludge particles of qualified size pass through the filter screen and the discharge port to complete the feeding, while the sludge particles of unqualified size remain on the top of the filter screen.
[0017] Furthermore, the second gear is meshed with the gear ring, and the push frame is slidably connected to the filter screen.
[0018] By adopting the above technical solution, the push frame rotates to push the unqualified sized particles blocked by the filter back to the top of the crushing roller, and the unqualified sized particles fall between the two crushing rollers and are crushed again by gravity, and the push frame cleans the filter.

Then, gravity causes the unqualified size particles to fall. The guide plates 10 are set to guide the unqualified size particles so that the unqualified size particles can accurately fall between the two crushing rollers 5 for secondary damage.
[0038] A roller 12 is connected to the upper part of the device body 1. A plurality of rollers 12 are provided. The plurality of rollers 12 are distributed in a circular array. The plurality of rollers 12 are divided into two groups. The push frame 11 is supported and guided by the plurality of rollers 12 to avoid the push frame 11 from deviating and causing structural failure, and to reduce some friction and wear.
[0039] Push frames 11 are connected to both sides of the device body 1. The push frames 11 are rotatably connected to the device body 1 and the retaining frame 9. The push frames 11 are in contact with two sets of rollers 12. The push frames 11 are slidably connected to the filter screen 8. A gear ring 13 is fixed to the inner ring of the push frame 11.
