Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sewage treatment, especially the technical field of sand and gravel separation. Background Art
[0002] With the acceleration of the industrialization process, the demand for sand and gravel resources in industries such as construction and mining is increasing day by day. However, during the process of sand and gravel extraction, transportation and use, a large amount of sewage and waste will be generated. If these sewage and waste are directly discharged without treatment, it will cause serious pollution to the environment, affecting the ecological balance and human health. In the prior art, generally, a filter screen is set in the conveying pipeline to intercept the sand and gravel, and then through multiple interceptions to clean the sand and gravel carried in the sewage.
[0003] The existing patent CN222641337U discloses a sewage sand and gravel separation device for concrete production. The separated gravel needs to slide down on the inclined first screen plate by its own gravity. Since the just-separated gravel adheres to some water and sand and gravel, it is easy to adhere to the first screen plate, which is likely to cause the accumulation of gravel on the first screen plate and affect the separation effect.
[0004] The existing patent CN119701479A discloses a continuous-operation sewage sand and gravel separation device, which solves the problem of gravel movement through a filter belt. However, there is still a lot of sand and gravel adhering to the gravel, resulting in a low recovery rate of sand and gravel, which is not conducive to the rational utilization of resources.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Embodiment 1: Refer to Figure 1 , the rapid separation intelligent sand and gravel separator of the present invention includes a separation box 1, a scraping belt 2, a scraping plate 21, a sewage inlet pipe 3, a flushing water inlet pipe 4 and a first screen plate 10. The upper end of the separation box 1 is open, and a horizontally arranged first screen plate 10 is provided inside the separation box 1. The first screen plate 10 is provided with first screen holes, and the first screen plate 10 divides the interior of the separation box 1 into an upper cavity located above and a lower cavity located below.
[0019] A scraping belt 2 is installed in the upper cavity. Four avoidance holes 20 are equidistantly distributed on the scraping belt 2. Every two avoidance holes 20 form a group, and the two avoidance holes 20 within the same group are located on the same vertical axis. The sewage inlet pipe 3 and the flushing water inlet pipe 4 are both vertically arranged. The sewage inlet pipe 3 and the flushing water inlet pipe 4 are respectively aligned with a group of avoidance holes 20. The outer diameters of the sewage inlet pipe 3 and the flushing water inlet pipe 4 are both smaller than the inner diameter of the avoidance holes 20. Four scraping plates 21 are fixed on the outer belt surface of the scraping belt 2. There is only one scraping plate 21 in the middle of the belt surface between two adjacent avoidance holes 20. The scraping plate 21 is perpendicular to the moving direction of the scraping belt 2. The gap between the lowermost scraping plate 21 and the first sieve plate 10 is 0.5 - 1 times the inner diameter of the first sieve holes. A discharge port is provided on the side wall of the upper cavity, and the lowermost end of the discharge port is flush with the upper end surface of the first sieve plate 10. The sewage inlet pipe 3, the flushing water inlet pipe 4 and the discharge port are arranged in sequence in the horizontal direction.
[0020] In order to enable the discharged gravel to move to a designated position, a downwardly inclined first discharge pipe 11 is provided on the outer wall of the separation box 1, and the first discharge pipe 11 surrounds the discharge port.
[0021] Embodiment Two: In order to avoid excessive splashing of sewage onto the scraping belt 2, the sewage inlet pipe 3 is vertically arranged. A first hose 30 connected to a sewage supply device is connected to the top end of the sewage inlet pipe 3. The sewage inlet pipe 3 is connected to a first cylinder 32 through a first connecting frame 31, and the first cylinder 32 drives the sewage inlet pipe 3 to move vertically up and down.
[0022] In order to prevent the gravel from being splashed too high when being flushed with flushing water, the flushing water inlet pipe 4 is vertically arranged. A second hose 40 connected to a flushing water supply device is connected to the top end of the flushing water inlet pipe 4. The flushing water inlet pipe 4 is connected to a second cylinder 42 through a second connecting frame 41, and the second cylinder 42 drives the flushing water inlet pipe 4 to move vertically up and down.
[0023] Embodiment Three: In order to separate the coarse and fine grit in the separated sewage, a downwardly inclined guide plate 12 is provided in the lower cavity. At the lowest point of the guide plate 12, a first partition plate 13 is provided vertically downward. The lower end surface of the first partition plate 13 is higher than the inner bottom wall of the lower cavity. A second partition plate 14 is fixed on the inner bottom wall of the lower cavity. The second partition plate 14 is located directly below the guide plate 12. The top end of the second partition plate 14 is lower than the top end of the first partition plate 13. The second partition plate 14 divides the lower cavity into a first cavity and a second cavity. The first partition plate 13 is inserted into the first cavity. A second discharge pipe 16 and a third discharge pipe 17 are respectively provided at the bottoms of the first cavity and the second cavity. A valve is provided on the second discharge pipe 16. A second sieve plate 15 that divides this area into upper and lower parts is provided in the area sandwiched by the second partition plate 14 and the second partition plate 14.
[0024] The guide plate 12 is inclined downward from the side where the discharge port of the separation tank 1 is located. The water with relatively less sand content is located upstream, and the grit adhering to the guide plate 12 can be effectively washed away.
[0025] In order to effectively discharge the grit accumulated at the bottoms of the first cavity and the second cavity, the bottom walls of the first cavity and the second cavity are both inclined planes that slope downward from the end of the second partition plate 14.
[0026] Embodiment 4: In order to prevent the second sieve plate 15 from being blocked after long-term use, the second sieve plate 15 is close to the upper end of the second partition plate 14. A mounting plate 18 is fixed on one side of the first partition plate 13. The mounting plate 18 is located directly above the second sieve plate 15. A plurality of backwashing nozzles 19 that spray water downward are provided on the lower end surface of the mounting plate 18.
[0027] The working process of the present invention: During the operation of the rapid separation intelligent sand and gravel separator of the present invention, the first cylinder 32 drives the sewage inlet pipe 3 to pass through the set of avoidance holes 20 originally located below it. The sewage supply device supplies sewage, and the sewage falls onto the first screen plate 10 for the first sand and gravel separation. The gravel that cannot pass through the first screen holes on the first screen plate 10 is left on the first screen plate 10, and the sand and gravel that can pass through the first screen holes flow into the lower cavity together with the sewage. After a period of time, the sewage supply device stops supplying sewage, and the first cylinder 32 drives the sewage inlet pipe to reset. The scraping belt 2 operates once, and the avoidance holes 20 sequentially come to the positions of the originally downstream avoidance holes 20. During this process, the scraping plate 21 also moves accordingly. The scraping plate 21 pushes the gravel separated in the first sand and gravel separation to the lower part of the flushing water inlet pipe 4. The second cylinder 42 drives the flushing water inlet pipe 4 to pass through the two avoidance holes 20 below. The flushing water supply device supplies flushing water, and the flushing water flushes the gravel, washing away some of the sand and gravel on the gravel. After a period of time, the flushing water supply device stops supplying flushing water, and the second cylinder 42 drives the flushing water inlet pipe 4 to reset, completing one flushing. During this flushing process, the sewage inlet pipe 3 operates once according to the previous operation mode, and then the scraping belt 2 operates once again. When the operation is completed, the washed gravel is pushed by the scraping plate 21 to the discharge port and leaves through the first discharge pipe 11. The gravel obtained from the first sand and gravel separation is scraped to the flushing position, and this process is repeated.
[0028] The sewage with sand and gravel generated during the above process enters the lower cavity and is guided by the guide plate 12 into the first cavity, and is filtered by the second screen plate 15 in the first cavity. The coarser sand and gravel remain in the first cavity, and the finer sand and gravel pass through the second screen plate 15 and enter the second cavity. The sand and gravel remaining in the first cavity are discharged at regular intervals after a period of precipitation. The sewage entering the second cavity is directly discharged from the third discharge pipe 17, and the two parts of sewage then enter the subsequent sand and water separation process.
[0029] Each time the first cavity discharges sand, the sewage inlet pipe 3 and the flushing water inlet pipe 4 stop working, and the backwashing nozzle 19 on the mounting plate 18 flushes the second screen plate 15, which can effectively prevent the second screen plate 15 from being blocked.
[0030] The above embodiments are illustrative of the present invention, not limiting of the present invention. Any solution obtained by simply transforming the present invention belongs to the protection scope of the present invention.
