Description

technical field [0001] This invention relates to solid and liquid separators for materials. Background technique [0002] The solid and liquid separator of the material is also called the compressor, which can effectively separate the solid part and the liquid part of the material, so that the solid part and the liquid part of the material can be used reasonably, effectively and reliably. Therefore, the solid-liquid part of the material Separators are widely used in daily industrial production. At present, the commonly used material solid-liquid separator is mainly composed of a frame and a pressing plate and a filter plate that are slidably assembled on the frame. There is a diaphragm inside, and there is a corresponding feed channel at the center of the pressure plate and filter plate, and a corresponding discharge channel at the bottom position. The end of the feed channel composed of all pressure plates and filter plates is connected with a feed pipe. , the feed pipe i...

AI Technical Summary

Problems solved by technology

[0003] 1. The central feeding is adopted (that is, the center of the pressure plate and the filter plate is provided with a corresponding feeding channel), not only the feeding time is long, which affects the production efficiency, but also the material entering the material chamber is unevenly distributed, which is not conducive to washing; What's more, the central feeding structure is adopted. During the solid-liquid separation and extrusion process of the material, the structural strength of the center of the filter plate is very low, the force is very small, and it cannot accept high extrusion force, so that the formed material is solid The water content is high, and the solid-liquid separation cannot be achieved completely, which increases the difficulty and cost of subsequent production; in addition, the single-channel discharge at the bottom not only affects the production efficiency due to the small discharge volume, but also is easy to block, which further affects the production efficiency;

[0004] 2. Without the filter cloth mechanism and the corresponding filter cloth regeneration mechanism, not only the unloading of the solid material after extrusion is troublesome, but also cannot be completely and cleanly unloaded, and the solid material during the extrusion process is very easy to remove the liquid in the material cavity of the filter plate. The discharge port is blocked, which affects the normal separation operation; what's more, there is no special discharge channel for the material liquid in the material cavity of the filter plate, so that the solid material in the extrusion process further blocks the liquid discharge port in the material cavity of the filter plate, which seriously affects the production efficiency ;

[0005] 3. The filter plate is made of a single-layer plastic plate. The structural strength of the filter plate is very low. During the long-term service process, the middle position of the filter plate is easy to be broken due to force, the frequency of maintenance and replacement is high, and the service life is short, which increases production. cost, reducing the production efficiency of the enterprise;

[0006] 4. The diaphragm of the pressure plate is usually made of PBT, which can withstand a small pressure, and the maximum pressure it can withstand is usually 8-10MPa, that is, the pressure it can withstand cannot exceed 10MPa, which makes the pressure plate unable to withstand high pressure during the extrusion process of materials. Large extrusion force, and then the extrusion effect on the material in the material cavity is not ideal, and the solid moisture content of the material formed in the material cavity is high, and it is further impossible to realize the complete separation of solid and liquid;

[0007] 5. After the solid and liquid of the material are squeezed and separated, when opening each pressing plate and filter plate to free up the unloading operation space, the opening of each pressing plate and filter plate adopts a combination of semi-automatic and manual methods. In the process of taking out the solid material, the filter plate often cannot be opened, which not only increases the labor intensity of the workers, but also the operation efficiency is very low;

[0008] 6. There is no material removal mechanism. After the solid and liquid of the material are squeezed and separated, when the material attached to the separator is cleaned, it is completed by the impact action between adjacent plates, which not only easily affects the structural strength and mechanical strength of the separator. performance, and when removing viscous materials, the greater the impact force, the stronger the adhesion of the materials on the separator, so that the materials attached to the separator cannot be effectively and thoroughly removed, and manual removal is required

[0009] In summary, due to the unreasonable structural design of the existing material solid-liquid separator, there are difficulties in operation, incomplete solid-liquid separation, low separation efficiency, troublesome cleaning, short service life, high maintenance frequency, poor reliability and practicability, etc. problems, seriously affecting the production efficiency of enterprises
