[0002] The mud waste liquid solid residue filter press is an industrial equipment used to separate solids and liquids, especially when treating mud or wastewater containing suspended solids. This equipment is used in many industries, including chemical, mining, oil exploration, food processing and construction engineering. The mud waste liquid solid residue filter press is a device used for solid-liquid separation. It is mainly used to treat materials such as mud, wastewater or sludge containing solid particles. In the process of industrial production and sewage treatment, a large amount of liquid waste containing solid residues is often generated. In order to reduce waste emissions, recycle valuable substances or meet environmental protection requirements, these wastes need to be treated and separated. The mud waste liquid solid residue filter press applies pressure to pass the waste liquid containing solid particles through filter media such as filter cloth, so that the solid particles are intercepted on the filter cloth to form a filter cake, and the liquid is discharged through the filter cloth, thereby achieving the purpose of solid-liquid separation.

[0003] At present, the filter press used for treating the solid residue of mud waste liquid needs to open the filter plates individually for treatment after the filtration is completed during use. The treatment is troublesome and cannot be carried out by multiple people quickly. The filter plates cannot be opened at the same time after the filtration is completed, which leads to a slow cleaning time. Therefore, a filter press for solid residue of mud waste liquid is proposed. Utility Model Content

The support members 5 are fitted with the filter press frame 1, and the support members 5 can slide left and right on the filter press frame 1. A hydraulic cylinder 2 is arranged on the right side of the filter press frame 1, and the hydraulic cylinder 2 is used to drive the extrusion member 3 to extrude the filter plate 4. The output end of the hydraulic cylinder 2 is provided with an extrusion member 3, and the extrusion member 3 cooperates with the filter press frame 1 to extrude the filter plate 4.

[0024] Mounting members 6 are provided on both sides of the outer wall of the filter press frame 1. The length of the mounting member 6 is greater than the width of the filter press frame 1. The mounting member 6 is used to install the guide member 7 to the filter press frame 1 through bolts. The inner side of the mounting member 6 is provided with a guide member 7. The outer wall of the guide member 7 is provided with a plurality of springs 8. A driving assembly is provided between the springs 8. The guide member 7 is used to guide the driving assembly. When the filter plate 4 is squeezed, the driving assembly can follow up and squeeze the spring 8. The reaction force of the spring 8 can enable the driving assembly to drive multiple filter plates 4 to open simultaneously.

[0025] The driving assembly includes a sliding member 9, which is arranged between the springs 8 and is slidably connected to the guide member 7. The sliding member 9 can slide left and right on the outer wall of the guide member 7. When sliding to the left, the spring 8 can be squeezed. The reaction force of the spring 8 can reset the sliding member 9. Limiting plates are arranged on both sides of the outer wall of the guide member 7. The limiting plates are used to prevent the sliding member 9 from rotating on the outer wall of the guide member 7. A groove matching the guide member 7 is arranged inside the sliding member 9. A connecting member 10 is arranged on the top of the sliding member 9. When the filter plate 4 is squeezed, the sliding member 9 can be driven by the connecting member 10 to squeeze the spring 8.
