Description

Technical Field

[0001] The utility model relates to the technical field of screw extrusion separators, in particular to a screw high-pressure extrusion separator with a screw self-cleaning function. Background Art

[0002] The screw extrusion separator, also known as the screw solid-liquid separator, is a device based on the principle of pressure filtration. It has high processing efficiency and separation effect. Its main working principle is to introduce the solid-liquid mixture into the processing area of ​​the filter cake filter through the feed port, and then use the action of the screw propeller to push the mixture forward. Due to the pressure difference inside the equipment, the liquid is squeezed out after being filtered through the filter screen, while the solid is retained on the filter screen to form a filter cake, which is finally discharged through the material discharge port.

[0003] After the spiral solid-liquid separator performs solid-liquid separation, solid residue will remain on the screw in the filter cartridge. When there are too many solid residues, the filter cartridge will be blocked, affecting the solid-liquid separation efficiency. Therefore, after the solid-liquid separation is completed, the screw in the filter cartridge needs to be cleaned to keep the screw clean. The existing cleaning method generally disassembles the filter cartridge to clean the screw, which is cumbersome, labor-intensive, and has low cleaning efficiency.

[0004] Therefore, the present application provides a spiral high-pressure extrusion separator with a screw self-cleaning function to meet the needs. Utility Model Content

[0005] The purpose of the present application is to provide a spiral high-pressure extrusion separator with a screw self-cleaning function, in which a nozzle is arranged on the filter cartridge to clean the screw, thereby reducing the difficulty of screw cleaning and improving the cleaning efficiency.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a spiral high-pressure extrusion separator with a screw self-cleaning function, comprising a separator body, a filter cartridge and a main motor are arranged on the separator body, a screw is rotatably connected in the filter cartridge, and the main motor drives the screw to rotate;

[0007] The filter cartridge is provided with a cleaning cartridge and an angle motor;

[0008] A spray pipe is rotatably connected to the cleaning cylinder, the spray pipe is parallel to the rotating shaft of the screw, a through slot is provided between the cleaning cylinder and the filter cylinder, and nozzles are arranged in a linear array on the spray pipe, and the nozzles are adapted to the size of the through slot;

[0009] The angle motor controls the rotation angle of the spray pipe;

[0010] A water pump is provided on one side of the separator body, and the spray pipe is connected to the water outlet of the water pump through a water pipe.

[0011] Preferably, there are two groups of cleaning cylinders which are arranged alternately, and one end of each group of cleaning cylinders is flush with one end of the filter cylinder.

[0012] Preferably, the angle motor is a dual-axis motor, one end of the spray pipe extends from the cleaning cylinder, and the extended ends of the two groups of spray pipes are both connected to one end of the dual-axis motor shaft through a synchronous belt transmission.

[0013] Preferably, the water pipe is connected to the protruding end of the spray pipe through a rotary joint.

[0014] Preferably, grooves are provided on the outer wall of the spray pipe, and the grooves are in multiple groups and arranged in a linear array. The spray heads are all positioned in the grooves, and the spray heads adopt fan-shaped nozzles.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] The utility model provides a cleaning cylinder on the filter cartridge, and the nozzle on the spray pipe can be used to pass through the through groove to effectively rinse and clean the rotating screw and remove solid residues remaining on the surface of the screw. At the same time, the angle motor is used to control the rotation of the spray pipe. When the spiral extrusion separator is working, the nozzle can be transferred into the cleaning cylinder for protection to prevent the solid and liquid materials from being squeezed and clogging the nozzle. Therefore, while ensuring the normal operation of the spiral extrusion separator, the tedious operation of disassembling the filter cartridge for manual cleaning is avoided, which significantly improves the cleaning efficiency, reduces the labor cost, keeps the screw and the inside of the filter cartridge clean, and ensures the efficient operation of the solid-liquid separator and the stability of the separation effect.
