Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and more specifically, to a sewage treatment solid-liquid separation device. Background Technique

[0002] A sewage treatment solid-liquid separation device is a device used to separate solid particles from sewage. It usually separates the solid substances in sewage through physical or chemical methods, thereby purifying the water quality. These devices play a key role in the sewage treatment system, helping to reduce the content of solid waste in sewage, improve the quality of water and meet environmental discharge standards;

[0003] However, the existing sewage treatment solid-liquid separation devices can quickly separate solid particles in sewage through filtration. However, after long-term use, the solid particles will block the particle filter screen inside the device, resulting in a decline in the filtration effect. The sewage cannot quickly seep out from inside the filter screen and the solid particles, thus affecting the working efficiency of the device for sewage separation.

[0004] In view of this, we propose a sewage treatment solid-liquid separation device. Utility Model Content

[0014] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0015] 1. The present application sets a filter frame that can rotate at high speed inside the collection box. The high-speed rotation of the filter frame generates centrifugal force, and the solid particles in the sewage will be quickly adsorbed on the inner wall of the filter frame, and the sewage will be quickly thrown out, which effectively improves the efficiency of solid-liquid separation. The silicone strip at one end of the extension frame contacts the inner wall of the filter frame. The filter frame rotates at high speed, and the extension frame and the silicone strip will press against the solids on the inner wall of the filter frame.

The upper end of the sealing box 17 is rotatably connected to a fixed block 19. The filter frame 12 rotates at high speed to generate centrifugal force. The solid particles in the sewage will be quickly adsorbed on the inner wall of the filter frame 12, and the sewage will be quickly thrown out, which effectively improves the efficiency of solid-liquid separation. The silicone strip 7 at one end of the extension frame 6 is in contact with the inner wall of the filter frame 12. The filter frame 12 rotates at high speed, and the extension frame 6 and the silicone strip 7 will press against the solids on the inner wall of the filter frame 12. The solid particles will not prevent the solids from being adsorbed on the inner wall of the filter frame 12 for a long time, thereby affecting the filtering effect of the filter frame 12.

[0024] Reference Figure 2 and Figure 3, a communication port 4 is provided on one side of the upper end face of the connection cover 3, a pair of lifting grooves 14 are provided on the inner wall of the rotating cylinder 11, which facilitates the staff to quickly take out the connection cover 3 and the filter frame 12. A pair of limiting blocks 13 are fixedly connected to the outer wall of the rotating cylinder 11. An insertion block 15 is fixedly connected to the lower end face of the filter frame 12. The fixed block 19 is in plug-in fit with the insertion block 15. Limiting grooves 16 are provided on both sides above the inner wall of the rotating disk 10, and the limiting blocks 13 are located inside the limiting grooves 16. The settings of the limiting blocks 13 and the insertion block 15 both play a good limiting role, making the rotation of the filter frame 12 more stable.

[0025] Refer to Figure 3 , the output end of the high-speed motor 18 extends out of the sealed box 17 and is fixedly connected to the fixed block 19. A water guide plate 20 is fixedly connected to the lower part of the outer wall of the sealed box 17. A communicating water outlet pipe 21 is fixedly connected to one side of the lower end face of the collection box 1. The water guide plate 20 plays a good role in guiding water, facilitating the rapid delivery of water to the water outlet pipe 21 for quick drainage.

[0026] Refer to Figure 4 , a toggle rod 22 is fixedly connected to the outer wall of the upper end of the extension frame 6. An adjustment groove 23 is provided at the upper end of the extension frame 6. A spherical block 24 is fixedly connected to the lower end of the fixed rod 5, and the spherical block 24 is located inside the adjustment groove 23. An extension groove 25 is provided at the lower part inside the adjustment groove 23. A rigid spring 26 is fixedly connected inside the extension groove 25, and one end of the rigid spring 26 is fixedly connected to the spherical block 24. A limiting ring 27 is fixedly connected to the upper part of the inner wall of the adjustment groove 23. A top block 28 is fixedly connected to one side of the upper end face of the rotating disk 10. By rotating and pushing the toggle rod 22 on the extension frame 6 through the top block 28, the movement of the toggle rod 22 drives the movement of the extension frame 6. Under the elastic force of the rigid spring 26, the extension frame 6 will impact the filter frame 12, thereby vibrating the filter frame 12. By continuously vibrating the filter frame 12, it is possible to prevent smaller solid particles from clogging the holes of the filter frame 12, thereby improving the filtering effect of the filter frame 12.

[0027] Working principle: When in use, the staff inserts one end of the sewage pipe into the connecting port 4 on the connecting cover 3 and starts the high-speed motor 18. The high-speed motor 18 drives the output end to rotate, and the rotation of the output end drives the fixed block 19 to rotate. The rotation of the fixed block 19 drives the limit block 13, the filter frame 12 and the rotating drum 11 to rotate synchronously. Since the limit block 13 on the rotating drum 11 is located in the limit groove 16 on the rotating disk 10, the rotation of the rotating drum 11 drives the rotating disk 10 to rotate, and the staff injects sewage into the rotating drum 11 and the filter frame through the sewage pipe. 12 inside, the filter frame 12 rotates at a high speed, quickly separating the sewage from the solid impurities in the sewage, the sewage passes through the filter frame 12 and falls into the water guide plate 20 at the bottom of the collection box 1, the water guide plate 20 guides the sewage without solids to the outlet pipe 21, and the outlet pipe 21 discharges the sewage. Due to the high-speed rotation of the filter frame 12, the solids in the sewage will be adsorbed on the inner wall of the filter frame 12, the fixing rod 5 on the connecting cover 3 extends into the filter frame 12, and the silicone strip 7 at one end of the extension frame 6 on the fixing rod 5 contacts the inner wall of the filter frame 12, and the filter frame 12 When the filter frame 12 is rotated, the extension frame 6 and the silicone strip 7 will press against the solids on the inner wall of the filter frame 12 to prevent the solids from being adsorbed on the inner wall of the filter frame 12 for a long time, thereby affecting the filtering effect of the filter frame 12. At the same time, the rotation of the rotating disk 10 will drive the top block 28 on the rotating disk 10 to rotate, and the rotation of the top block 28 will push the toggle rod 22 on the extension frame 6, thereby driving the toggle rod 22 to move. The movement of the toggle rod 22 drives the extension frame 6 to move, and the rigid spring 26 fixedly connected to the spherical block 24 is deformed and generates elastic force. When the top block 28 passes the toggle rod 22, the toggle rod 22 moves. , the rigid spring 26 rebounds and drives the extension frame 6 to the initial position. Under the elastic force of the rigid spring 26, the extension frame 6 will hit the filter frame 12, thereby causing the filter frame 12 to vibrate. By continuously vibrating the filter frame 12, smaller solid particles can be prevented from clogging the holes of the filter frame 12, thereby improving the filtering effect. After the filtration is completed, take out the sewage pipe, rotate and remove the connecting cover 3, take out the rotating cylinder 11 and the filter frame 12 through the pulling groove 14, and the plug 15 is separated from the fixed block 19. The staff can clean up the sewage solids inside the filter frame 12.
