Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation devices, in particular to a solid-liquid separation device capable of preventing pipeline blockage. Background Art

[0002] "Water pollution prevention and control" refers to the prevention and control of the phenomenon that the chemical, physical, biological or radioactive characteristics of water bodies are changed due to the intervention of certain substances, thereby affecting the effective use of water, endangering human health or damaging the ecological environment, and causing water quality deterioration. Among them, the physical prevention measure is the use of solid-liquid separation. Although the existing solid-liquid separation device can separate sewage from solid impurities when in use, after long-term use, the impurities in the sewage will accumulate and be adsorbed at the liquid outlet. In addition, since the internal dead corners of the solid-liquid separator are difficult to clean, impurities are attached to the surface of the filter plate and the filter cartridge, which is inconvenient for personnel to clean, which can easily cause the solid-liquid separator to be blocked, so it is necessary to improve it.

A No. 2 plug block 19 is fixedly installed on the bottom surface of the filter cartridge 20. The No. 1 plug block 7 is inserted into the No. 1 slot 22, and the No. 2 plug block 19 is inserted into the No. 2 slot 18. The cylinder 17, the fixing rod 21 and the connecting block 6 are on the same axis, so that the components of the filter mechanism can be accurately docked and fixed, ensuring the stability and alignment between the filter cartridge 20, the motor 5 and the filter plate 13, reducing vibration and wear during operation, and improving the filtering efficiency and the service life of the equipment. A limit ring 12 is fixedly installed on the bottom surface of the box cover 3, and the diameter of the limit ring 12 is The inner wall diameters of the filter cartridge 20 are equal, so that the filter cartridge 20 can be stably rotated inside the box body 1 to avoid vibration of the filter cartridge 20 during operation. The lifting mechanism includes a cylinder 23, and a telescopic rod 24 is fixedly installed at the output end of the cylinder 23. A connecting plate 25 is fixedly installed on the side of the box cover 3, and the telescopic rod 24 is fixedly installed with the connecting plate 25. A lower fixed block 8 and an upper fixed block 9 are fixedly installed inside the box body 1. The filter plate 13 is located between the lower fixed block 8 and the upper fixed block 9, and the filter plate 13 is slidably connected inside the box body 1, so that the position of the filter plate 13 can be limited to avoid the filter plate 13 from falling out of the box body 1.

[0027] Embodiment 2

[0028] See also Figure 3 , Figure 5-6After the filter cartridge 20 and the filter plate 13 extend from the inside of the box body 1, the nut 16 is screwed on the surface of the threaded end 15, and the nut 16 moves upward for a certain distance. Then, the cylinder 23 is started again, and the output end of the cylinder 23 drives the telescopic rod 24 to continue to lift the connecting plate 25, so that the box cover 3 continues to move upward. Since the nut 16 is screwed for a certain distance, the box cover 3 will not drive the filter cartridge 20 and the filter plate 13 to move upward when the box cover 3 moves upward. At this time, the box cover 3 drives the motor 5 and the connecting block 6 to move upward, so that the connecting block 6 is separated from the fixing rod 21. Then, the personnel lifts the filter cartridge 20 upward to disengage the No. 2 plug block 19 from the No. 2 slot 18 on the cylinder 17, so that the personnel can remove the filter cartridge 20 for maintenance or replacement.

[0029] Working principle: When the solid-liquid separator is used, the solid-liquid mixture enters the filter cartridge 20 inside the housing 1 from the liquid inlet 4, the motor 5 is started, and the output end of the motor 5 drives the connecting block 6 to rotate, and then the connecting block 6 drives the fixing rod 21 to rotate. Since the No. 2 plug block 19 is inserted into the No. 2 slot 18 on the cylinder 17, the filter cartridge 20 can rotate with the cylinder 17, so that the filter cartridge 20 rotates inside the housing 1, so that the liquid in the solid-liquid mixture is discharged from the filter cartridge 20, and the solid remains in the filter cartridge 20. When the liquid is discharged from the filter cartridge 20, it will flow to the filter plate 13. Secondary filtration of the filter plate 13 can prevent solids remaining in the liquid from flowing to the liquid outlet 2 and clogging the pipeline of the solid-liquid separator. After using the solid-liquid separator, start the cylinder 23, and the output end of the cylinder 23 drives the telescopic rod 24 to move upward, and the telescopic rod 24 drives the connecting plate 25 to move upward, so that the connecting plate 25 drives the box cover 3 to move upward. Under the action of the round rod 14 and the nut 16, the box cover 3 drives the filter plate 13 and the filter cartridge 20 on the filter plate 13 to extend from the inside of the box body 1, so that personnel can clean the filter plate 13 and the filter cartridge 20, which is convenient for personnel to operate.
