Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automatic sewage cyclone sand separators, specifically an automatic sewage cyclone sand separator. Background Technology
[0002] With the national policy of actively advocating the construction of environmentally friendly concrete mixing plants, more and more concrete mixing plants are installing sand and gravel separators. Residual concrete from the trucks is washed out and separated into sand, gravel, and slurry by the separator. The slurry inevitably contains fine sand. Currently, hydrocyclones are often used to remove sand from the slurry. The sand-containing slurry enters the hydrocyclone through an inlet located on its side wall. The separated fine sand is discharged through a drain at the bottom of the hydrocyclone, and the desanded slurry overflows through an overflow port at the top of the hydrocyclone. This allows for easy storage and reuse in the next round of concrete production. However, fine sand easily adheres to the inner wall of the hydrocyclone's drain port, requiring regular cleaning. Otherwise, blockage of the drain port can lead to equipment malfunction.
[0003] The anti-clogging hydrocyclone disclosed in Chinese Utility Model Patent Application Publication CN214021420U, although solving the problem of fine sand adhering to the inner wall of the discharge port, still has the following drawbacks: 1. When the anti-clogging hydrocyclone desander discharges sand, the cone above the discharge port is truncated cone-shaped with a larger top and smaller bottom, which can lead to sand accumulation at the top of the discharge port. When there is a lot of sand accumulation, the discharge will be slower, which is not conducive to use. 2. Although the above-mentioned anti-clogging hydrocyclone can solve the problem of discharge port blockage, when fine sand combines with water, the adsorption force of fine sand will increase. At this time, air jet cannot completely clean the fine sand on the inner wall of the discharge port, resulting in incomplete cleaning. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1:
[0026] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic sewage discharge cyclone sand remover, including a cyclone chamber 1, which is cylindrical. An upper cone 5 is fixedly connected to the bottom of the cyclone chamber 1. The upper cone 5 is a frustum-shaped cone, wider at the top and narrower at the bottom. The top of the upper cone 5 is the same size as the bottom of the cyclone chamber 1. A rotating body 6 is rotatably connected to the bottom of the upper cone 5. The rotating body 6 is also a frustum-shaped cone, wider at the top and narrower at the bottom. The top of the rotating body 6 is the same size as the bottom of the upper cone 5 and fits tightly. A rotating plate 7 is fixedly connected to the outer end of the rotating body 6. The rotating plate 7 is L-shaped. A first scraper 8 is fixedly connected to the inner wall of the rotating body 6. The top of the first scraper 8 is flush with the top of the rotating body 6. A second scraper 9 is fixedly connected to the lower half of the upper cone 5. The outer wall of the second scraper 9 is flush with the inner wall of the rotating body 6. The inner wall of the rotating body 6 is tightly attached, the bottom of the second scraper 9 is flush with the bottom of the rotating body 6, the front of the cyclone chamber 1 is fixedly connected to the feed port 2, the inside of the cyclone chamber 1 is provided with an overflow pipe 4, the outer end of the overflow pipe 4 is provided with an outer pipe 3, the outer pipe 3 is located at the top of the cyclone chamber 1, the outer end of the upper cone 5 is fixedly connected to a fixing plate 10, the bottom of the fixing plate 10 is fixedly connected to a support rod 11, there are three support rods 11 and they are arranged in a circumferential array with the fixing plate 10, the bottom of the rotating body 6 is rotatably connected to a lower cone 19, the top of the lower cone 19 is the same size as the bottom of the rotating body 6 and the lower cone 19 is a frustum shape with a larger top and a smaller bottom, the outer wall of the first scraper 8 is tightly attached to the inner wall of the lower cone 19 and the bottom of the first scraper 8 is flush with the bottom of the lower cone 19.
[0027] When the anti-clogging cyclone sand separator is discharging sand, the cone above the discharge port is shaped like a frustum, wider at the top and narrower at the bottom, which can cause sand to accumulate at the top of the discharge port. When there is a lot of sand, the discharge will be slower, which is not conducive to use. Therefore, there is an automatic discharge cyclone sand separator. When the anti-clogging cyclone sand separator is discharging sand, at regular intervals, the rotating plate 7 is rotated clockwise and counterclockwise once each. This causes the rotating body 6 to rotate clockwise first, driving the first scraper 8 to rotate. This causes the first scraper 8 to scrape the fine sand on the inner wall surface of the lower cone 19. The second scraper 9 scrapes the inner wall of the rotating body 6. When the second scraper 9 collides with the first scraper 8, the rotating body 6 rotates counterclockwise again, and the second scraper 9 scrapes the inner wall of the lower cone 19 a second time. This prevents the discharge speed from slowing down due to sand accumulation at the bottom of the lower cone 19.
[0028] Example 2:
[0029] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic sewage discharge cyclone sand remover, wherein a sewage discharge pipe 12 is fixedly connected to the bottom of the lower cone 19, the sewage discharge pipe 12 is cylindrical, and a fixing frame 20 is fixedly connected to the outer end of the sewage discharge pipe 12. There are three fixing frames 20, each corresponding to a support rod 11. The end of the fixing frame 20 away from the sewage discharge pipe 12 is fixedly connected to the support rod 11. The fixing frame 20 is located at the top of the sewage discharge pipe 12. A groove 13 is formed on the left outer wall of the sewage discharge pipe 12. The groove 13 is T-shaped, and a pressing plate 14 is slidably connected to the inner wall of the groove 13. The pressing plate 14 is a... The T-shaped groove 13 is fitted with a spring 15 fixedly connected to the bottom of the pressing plate 14. The end of the spring 15 away from the pressing plate 14 is fixedly connected to the inner bottom wall of the groove 13. A first connecting plate 16 is fixedly connected to the bottom of the pressing plate 14. The first connecting plate 16 is L-shaped. A second connecting plate 18 is fixedly connected to the bottom right side of the first connecting plate 16. A third scraper 17 is fixedly connected to the top of the second connecting plate 18. The third scraper 17 is annular and its outer side wall is close to the inner side wall of the drain pipe 12. Both the top and bottom of the third scraper 17 are arc-shaped.
[0030] While existing anti-clogging hydrocyclones can solve the problem of discharge port blockage, the combination of fine sand and water increases the adsorption force of the fine sand. At this time, air jets cannot completely remove the fine sand from the inner wall of the discharge port, resulting in incomplete cleaning. Therefore, an automatic cyclone sand remover is developed. When the anti-clogging hydrocyclone sand remover is discharging sand, the pressing plate 14 is manually pressed at intervals, causing the spring 15 at the bottom of the pressing plate 14 to contract. At this time, the pressing plate 14 drives the first connecting plate 16 to move downward, and the second connecting plate 18 and the third scraper 17 move downward accordingly. This causes the third scraper 17 to move up and down on the inner wall of the sewage pipe 12, thereby scraping away the fine sand on the inner wall of the sewage pipe 12, achieving a more thorough cleaning. The rounded top and bottom of the third scraper 17 reduce its impact on the sand discharge speed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
