Description

Technical Field

[0001] The present invention relates to the technical field of sewage separation equipment, and specifically to a sewage coagulation sedimentation separation device for building construction. Background Technique

[0002] Building construction is the process of building a building and is a production activity in the implementation stage of project construction; during construction processes such as drilling, piling, and excavation, various mud slurries will be generated. The mud slurries affect the working environment and need to be treated and discharged from the working area. Sewage treatment generally goes through three stages: primary treatment, biochemical treatment, and advanced treatment. In the primary treatment stage, flocculants and lime are used to precipitate suspended solids, separating the precipitate from the water; biochemical treatment is to treat the organic matter in the precipitate remaining after primary treatment to reduce the number of bacteria in the precipitate; advanced treatment is to perform secondary sterilization treatment on the sewage after primary treatment.

[0003] Among them, after the sewage has completed sedimentation, the sewage will show two stratification phenomena: supernatant and precipitate. If the separation is carried out by means of suction with a straw at this time, when the straw reaches the boundary line between the supernatant and the precipitate, the straw will suck up the bottom precipitate, resulting in a decline in separation quality. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a sewage coagulation sedimentation separation device for building construction, including a cylinder. The bottom of the inner wall of the cylinder is connected through a hexagonal pipe. The top of the hexagonal pipe is fixedly connected with a fixed frame. The bottom of the fixed frame is fixedly connected with two electric telescopic rods, and the end of the electric telescopic rod away from the fixed frame is fixedly connected with a piston plate;

[0005] A waste removal mechanism, the waste removal mechanism includes four first telescopic rods fixedly connected to the bottom of the inner wall of the cylinder. A first spring is fixedly connected to the outer wall of the four first telescopic rods. The other end of the first telescopic rod is fixedly connected with a sliding disc. A first discharge port is opened on the outer wall of the hexagonal pipe. A separation component is fixedly connected to the inner wall of the first telescopic rod;

[0006] Drainage mechanism, the drainage mechanism includes a sliding groove opened on the inner wall of the cylinder, a second discharge port is opened on the side wall of the sliding groove, a sliding baffle is slidably connected to the inner wall of the sliding groove, a third discharge port is opened on the side wall of the sliding baffle, a contact plate is fixedly connected to the inner wall of the sliding baffle, a fixed block is fixedly connected to the side of the sliding baffle away from the contact plate, and a spring telescopic rod is fixedly connected to the bottom of the fixed block. Before use, install the cylinder at the required position and put the sewage to be precipitated into the interior of the cylinder, and then start precipitation. After the sewage in the cylinder is stratified, connect the power supply of the electric telescopic rod. The extended electric telescopic rod drives the piston plate to slide downward, so that the piston plate is in contact with the inner wall of the cylinder, and a closed space is formed by the top of the sliding disc, the outer wall of the hexagonal tube, the inner wall of the cylinder and the bottom of the piston plate. As the electric telescopic rod drives the piston plate to slide downward, the downward pushing force of the piston plate forces the sliding disc to slide downward along the outer wall of the hexagonal tube through the sewage. The downward moving sliding disc finally crosses the highest end of the first discharge port, causing the inner wall of the first discharge port to be misaligned with the top of the sliding disc, forming a gap. At this time, the sewage in the closed space is affected by high pressure and will force the sediment to enter the interior of the hexagonal tube through the above gap. Through the application of the above components, when the equipment discharges the bottom sediment, the phenomenon of mixing of the sediment and the supernatant can be effectively reduced.

[0007] Preferably, the separation component includes three collecting square tubes connected through the inner wall of the first telescopic rod, a filter screen is fixedly connected to the bottom of the collecting square tube, and a hydraulic telescopic tube is connected through the side wall of the collecting square tube.

[0008] Preferably, the separation component further includes a second spring fixedly connected to the side wall of the hydraulic telescopic tube. The other end of the hydraulic telescopic tube is fixedly connected to a U-shaped sliding plate. A scraper is rotatably connected to the inner wall of the U-shaped sliding plate. A first spiral spring is fixedly connected to the inner wall of the scraper. Using the characteristic that the piston plate slides downward when discharging the sediment as described above, a drainage mechanism is provided inside the equipment. When the piston plate moves downward, the bottom of the piston plate will contact the top of the contact plate as shown in Figure 3 this state. At this time, the downward moving piston plate will push the sliding baffle to slide downward along the inner wall of the sliding groove through the contact plate, so that the third discharge port moves downward synchronously, and a gap for discharging outward is formed between the third discharge port and the second discharge port. At this time, the bottom sediment has been completely discharged outward through the first discharge port, and the remaining supernatant in the cylinder will be discharged outward through the gap between the third discharge port and the second discharge port. At this time, the closed space composed of the sliding disc, the hexagonal tube, the cylinder and the piston plate disappears, so that the downward pushing force of the piston plate cannot force the sliding disc to move downward through the supernatant. The sliding disc is reset under the push of the first spring. At this time, the bottom of the sliding disc contacts the bottom of the contact plate, and the upward moving sliding disc will force the remaining supernatant to be discharged outward through the gap between the third discharge port and the second discharge port. Through the application of the above components, the rapid recovery of the supernatant is realized.

[0009] Preferably, the separation component further includes a discharge port opened at the top of the filter screen. A slag discharge pipe is fixedly connected to the inner wall of the discharge port. A scraping component is fixedly connected to one end of the three collecting square pipes away from the hexagonal pipe. By using the characteristic that the above-mentioned sediment is discharged outward through the discharge port, a separation component is arranged inside the device. When the impurities are sprayed into the hexagonal pipe through the discharge port, the sprayed sediment will contact the outer wall of the U-shaped sliding plate, forcing the U-shaped sliding plate to drive the scraper to move towards the collecting box. During this process, the sediment will pass through the filter screen again. At this time, impurities with larger particles or flocculates in the sediment will stay on the top of the filter screen. And every time the piston plate slowly moves down a certain distance, the sliding disc moves down a certain distance synchronously. After the moving sliding disc exceeds the discharge port by a certain distance, under the push of the first spring, while the sliding disc resets, the sliding disc will cover the discharge port, so that the sediment will no longer discharge impurities outward through the discharge port. At this time, the pressure on the U-shaped sliding plate decreases, and the second spring releases the pressure, so that the U-shaped sliding plate drives the scraper to reset synchronously. During the reset process, the scraper will rotate around the connection point, so that the impurities on the top of the filter screen will not limit the reset of the scraper. When the piston plate continues to move down, the externally sprayed sediment will force the U-shaped sliding plate to move outward again. When the outwardly moving U-shaped sliding plate drives the scraper to move again, the side wall of the scraper will contact the inner wall of the U-shaped sliding plate synchronously, restricting the rotation of the scraper. At this time, the lateral movement of the scraper will drive the large impurities and flocculates on the top of the filter screen to move laterally towards the discharge port, and finally the impurities on the top of the filter screen will be discharged outward from the sludge discharge pipe through the discharge port and the slag discharge pipe. Through the application of the above components, when the sediment is discharged, the sludge and large impurities can be effectively separated.

[0010] Preferably, the scraping component includes a sludge discharge pipe connected through the bottom of the slag discharge pipe. A collecting box is fixedly connected to one end of the three collecting square pipes away from the hexagonal pipe. A hydraulic pipe is connected through the bottom of the collecting box.

[0011] Preferably, the scraping component further includes a piston block slidably connected to the inner wall of the hydraulic pipe. A pushing round rod is fixedly connected to the bottom of the piston block. An installation frame is fixedly connected to one end of the pushing round rod away from the piston block.

[0012] Preferably, the rubbing component further includes a right-angle groove opened on the side wall of the mounting frame. A rotating plate is rotatably connected to the inner wall of the right-angle groove. A second volute spring is fixedly connected to the inner wall of the rotating plate. By utilizing the characteristic that the hydraulic telescopic tube is compressed by the lateral movement of the U-shaped sliding plate, a rubbing component is arranged inside the device. When the hydraulic telescopic tube is pressed, the liquid inside the hydraulic telescopic tube will enter the collection box. The solution inside the collection box increases, forcing the piston block to slide downward along the inner wall of the hydraulic tube. The downward-moving piston block drives the mounting frame to move downward synchronously through the push rod. At this time, the downward-moving mounting frame drives the rotating plate to move downward synchronously, so that the rotating plate can rub and clean the inner wall of the sludge discharge pipe, avoiding the accumulation and drying of impurities on the inner wall of the sludge discharge pipe, resulting in blockage inside the sludge discharge pipe and affecting the discharge efficiency of the device.

[0013] Preferably, one end of the spring telescopic rod away from the fixed block is fixedly connected to the outer wall of the cylinder. The outer wall of the sliding disc is slidably connected to the inner wall of the cylinder. The inner wall of the sliding disc is slidably connected to the outer wall of the hexagonal tube. The outer wall of the piston plate is slidably connected to the inner wall of the cylinder. The inner wall of the piston plate is slidably connected to the outer wall of the hexagonal tube.

[0014] The present invention has the following beneficial effects:

[0015] (1) By utilizing the characteristic of stratification after sewage precipitation, a waste discharge mechanism and a drainage mechanism are arranged inside the device. Before use, the cylinder is installed at the required position, and the sewage to be precipitated is put into the inside of the cylinder. Then precipitation starts. After the sewage inside the cylinder is stratified, the power supply of the electric telescopic rod is turned on. The extended electric telescopic rod drives the piston plate to slide downward, so that the piston plate contacts the inner wall of the cylinder, and a closed space is formed among the top of the sliding disc, the outer wall of the hexagonal tube, the inner wall of the cylinder and the bottom of the piston plate. As the electric telescopic rod drives the piston plate to slide downward, the downward pushing force of the piston plate forces the sliding disc to slide downward along the outer wall of the hexagonal tube through the sewage. The downward-moving sliding disc finally crosses the highest end of the first discharge port, causing the inner wall of the first discharge port to be misaligned with the top of the sliding disc, forming a gap. At this time, the sewage in the closed space is affected by high pressure and will force the sediment to enter the hexagonal tube through the above gap. Through the application of the above components, when the device discharges the bottom sediment, the phenomenon of mixing of the sediment and the supernatant can be effectively reduced.

[0016] (2) By utilizing the characteristic that the piston plate slides downward when discharging the sediment, a drainage mechanism is arranged inside the device. When the piston plate moves downward, the bottom of the piston plate will contact the top of the contact plate as shown in Figure 3At this state, the downward-moving piston plate will push the sliding baffle along the inner wall of the sliding groove through the contact plate, causing the third discharge port to move downward synchronously, so that a gap for outward discharge is formed between the third discharge port and the second discharge port. At this time, the sediment at the bottom has been completely discharged outward through the first discharge port, and the remaining supernatant liquid inside the cylinder will be discharged outward through the gap between the third discharge port and the second discharge port. At this time, the sealed space composed of the sliding disc, hexagonal tube, cylinder and piston plate disappears, so that the force pushing the piston plate downward cannot force the sliding disc to move downward through the supernatant liquid. The sliding disc is reset under the push of the first spring. At this time, the bottom of the sliding disc contacts the bottom of the contact plate, and the upward-moving sliding disc will force the remaining supernatant liquid to be discharged outward through the gap between the third discharge port and the second discharge port. Through the application of the above components, the rapid recovery of the supernatant liquid is realized.

[0017] (3) Taking advantage of the characteristic that the above sediment is discharged outward through the first discharge port, the present invention is provided with a separation component inside the device. When the impurity sprays into the hexagonal tube through the first discharge port, the sprayed sediment will contact the outer wall of the U-shaped sliding plate, forcing the U-shaped sliding plate to drive the scraper to move towards the collection box. During this process, the sediment will pass through the filter screen again. At this time, impurities with larger particles or flocs in the sediment will stay on the top of the filter screen. And every time the piston plate slowly moves downward by a certain distance, the sliding disc moves downward synchronously by a certain distance. After the downward-moving sliding disc exceeds the first discharge port by a certain distance, under the push of the first spring, while the sliding disc is reset, the sliding disc will cover the first discharge port, so that the sediment will no longer discharge impurities outward through the first discharge port. At this time, the pressure on the U-shaped sliding plate decreases, and the second spring releases pressure, causing the U-shaped sliding plate to drive the scraper to reset synchronously. During the reset process, the scraper will rotate around the connection point, so that the impurities on the top of the filter screen will not restrict the reset of the scraper. When the piston plate continues to move downward, the externally sprayed sediment will force the U-shaped sliding plate to move outward again. When the outward-moving U-shaped sliding plate drives the scraper to move again, the side wall of the scraper will contact the inner wall of the U-shaped sliding plate synchronously, restricting the rotation of the scraper. At this time, the lateral movement of the scraper will drive the large impurities and flocs on the top of the filter screen to move laterally towards the discharge port, and finally the impurities on the top of the filter screen will be discharged outward through the discharge port and the slag discharge pipe from the sludge discharge pipe. Through the application of the above components, when the sediment is discharged, the sludge and large impurities can be effectively separated.

[0018] (4) The present invention utilizes the characteristic that the above-mentioned hydraulic telescopic pipe is compressed by the lateral movement of the U-shaped sliding plate. A scraping component is arranged inside the device. When the hydraulic telescopic pipe is pressed, the liquid inside the hydraulic telescopic pipe will enter the inside of the collection box. The solution inside the collection box increases, forcing the piston block to slide downward along the inner wall of the hydraulic pipe. The downward-moving piston block drives the mounting bracket to move downward synchronously through the push rod. At this time, the downward-moving mounting bracket drives the rotating plate to move downward synchronously, so that the rotating plate can scrape and clean the inner wall of the sludge discharge pipe, avoiding the accumulation and drying of impurities on the inner wall of the sludge discharge pipe, resulting in blockage inside the sludge discharge pipe and affecting the discharge efficiency of the device.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Example 1, please refer to Figure 1 - Figure 3 , the present invention is a sewage coagulation sedimentation separation device for building construction, including a cylinder 1. The bottom of the inner wall of the cylinder 1 is connected through a hexagonal tube 11. The top of the hexagonal tube 11 is fixedly connected with a fixed frame 12. The bottom of the fixed frame 12 is fixedly connected with two electric telescopic rods 13. The end of the electric telescopic rod 13 away from the fixed frame 12 is fixedly connected with a piston plate 14;

[0032] The impurity removal mechanism 2 includes four first telescopic rods 21 fixedly connected to the bottom of the inner wall of the cylinder 1. A first spring 23 is fixedly connected to the outer walls of the four first telescopic rods 21. The other end of the first telescopic rod 21 is fixedly connected with a sliding disc 22. A first discharge port 24 is opened on the outer wall of the hexagonal tube 11. A separation assembly 4 is fixedly connected to the inner wall of the first telescopic rod 21;

[0033] Drainage mechanism 3, the drainage mechanism 3 includes a sliding groove 31 opened on the inner wall of the cylinder 1, a second discharge port 32 is opened on the side wall of the sliding groove 31, a sliding baffle 33 is slidably connected to the inner wall of the sliding groove 31, a third discharge port 34 is opened on the side wall of the sliding baffle 33, a contact plate 35 is fixedly connected to the inner wall of the sliding baffle 33, a fixed block 36 is fixedly connected to the side of the sliding baffle 33 away from the contact plate 35, a spring telescopic rod 37 is fixedly connected to the bottom of the fixed block 36. Before use, install the cylinder 1 at the required position and put the sewage to be precipitated into the interior of the cylinder 1, and then start precipitation. After the sewage in the cylinder 1 is stratified, connect the power supply of the electric telescopic rod 13. The extended electric telescopic rod 13 drives the piston plate 14 to slide downward, so that the piston plate 14 contacts the inner wall of the cylinder 1, making a closed space formed by the top of the sliding disc 22, the outer wall of the hexagonal tube 11, the inner wall of the cylinder 1 and the bottom of the piston plate 14. As the electric telescopic rod 13 drives the piston plate 14 to slide downward, the downward pushing force of the piston plate 14 forces the sliding disc 22 to slide downward along the outer wall of the hexagonal tube 11 through the sewage. The downward moving sliding disc 22 finally crosses the highest end of the first discharge port 24, making the inner wall of the first discharge port 24 misaligned with the top of the sliding disc 22, forming a gap. At this time, the sewage in the closed space is affected by high pressure and will force the sediment to enter the interior of the hexagonal tube 11 through the above gap. Through the application of the above components, when the device discharges the bottom sediment, the phenomenon of mixing of sediment and supernatant can be effectively reduced.

[0034] Embodiment 2, please refer to Figure 4 - Figure 8 , the present invention is a sewage coagulation sedimentation separation device for building construction. On the basis of Example 1, the separation component 4 includes three collecting square tubes 41 connected through the inner wall of the first telescopic rod 21, a filter screen 42 is fixedly connected to the bottom of the collecting square tube 41, and a hydraulic telescopic tube 43 is connected through the side wall of the collecting square tube 41.

[0035] The separation component 4 further includes a second spring 44 fixedly connected to the side wall of the hydraulic telescopic tube 43. The other end of the hydraulic telescopic tube 43 is fixedly connected to a U-shaped sliding plate 45. A scraper 46 is rotatably connected to the inner wall of the U-shaped sliding plate 45. A first volute spring 47 is fixedly connected to the inner wall of the scraper 46. Using the characteristic that the piston plate 14 slides downward when discharging the sediment as described above, a drainage mechanism 3 is arranged inside the device. When the piston plate 14 moves downward, the bottom of the piston plate 14 will contact the top of the contact plate 35 as shown in Figure 3At this state, the downward-moving piston plate 14 will push the sliding baffle 33 to slide downward along the inner wall of the sliding groove 31 through the contact plate 35, so that the third discharge port 34 moves downward synchronously, and a gap for outward discharge is formed between the third discharge port 34 and the second discharge port 32. At this time, the sediment at the bottom has been completely discharged outward through the first discharge port 24, and the supernatant remaining inside the cylinder 1 will be discharged outward through the gap between the third discharge port 34 and the second discharge port 32. At this time, the sealed space composed of the sliding disc 22, the hexagonal tube 11, the cylinder 1 and the piston plate 14 disappears, so that the force pushing the piston plate 14 downward cannot force the sliding disc 22 to move downward through the supernatant. The sliding disc 22 is reset under the push of the first spring 23. At this time, the bottom of the sliding disc 22 contacts the bottom of the contact plate 35, and the upward-moving sliding disc 22 will force the remaining supernatant to be discharged outward through the gap between the third discharge port 34 and the second discharge port 32. Through the application of the above components, the rapid recovery of the supernatant is realized.

[0036] The separation component 4 further includes a discharge port 48 opened at the top of the filter screen 42. A slag discharge pipe 49 is fixedly connected to the inner wall of the discharge port 48. One end of the three collecting square pipes 41 away from the hexagonal pipe 11 is fixedly connected with a rubbing component 5. Taking advantage of the characteristic that the above-mentioned sediment is discharged outward through the first discharge port 24, a separation component 4 is arranged inside the device. When the impurities are sprayed into the hexagonal pipe 11 through the first discharge port 24, the sprayed sediment will contact the outer wall of the U-shaped sliding plate 45, forcing the U-shaped sliding plate 45 to drive the scraper 46 to move towards the collecting box 52. During this process, the sediment will pass through the filter screen 42 again. At this time, impurities with larger particles or flocculates in the sediment will stay on the top of the filter screen 42. And every time the piston plate 14 slowly moves down a certain distance, the sliding disc 22 moves down a certain distance synchronously. After the moving-down sliding disc 22 exceeds the first discharge port 24 by a certain distance, under the push of the first spring 23, while the sliding disc 22 resets, the sliding disc 22 will cover the first discharge port 24, so that the sediment will no longer discharge impurities outward through the first discharge port 24. At this time, the pressure on the U-shaped sliding plate 45 decreases, and the second spring 44 releases the pressure, enabling the U-shaped sliding plate 45 to drive the scraper 46 to reset synchronously. During the reset process, the scraper 46 will rotate around the connection point, so that the impurities on the top of the filter screen 42 will not restrict the reset of the scraper 46. When the piston plate 14 continues to move down, the externally sprayed sediment will force the U-shaped sliding plate 45 to move outward again. When the outward-moving U-shaped sliding plate 45 drives the scraper 46 to move again, the side wall of the scraper 46 will synchronously contact the inner wall of the U-shaped sliding plate 45, restricting the rotation of the scraper 46. At this time, the lateral movement of the scraper 46 will drive the large impurities and flocculates on the top of the filter screen 42 to move laterally towards the discharge port 48, and finally the impurities on the top of the filter screen 42 will be discharged outward through the discharge port 48 and the slag discharge pipe 49 from the sludge discharge pipe 51. Through the application of the above components, when the sediment is discharged, the sludge and large impurities can be effectively separated.

[0037] The rubbing component 5 includes a sludge discharge pipe 51 connected through the bottom of the slag discharge pipe 49. One end of the three collecting square pipes 41 away from the hexagonal pipe 11 is fixedly connected with a collecting box 52. The bottom of the collecting box 52 is connected through a hydraulic pipe 53.

[0038] The rubbing component 5 further includes a piston block 55 slidably connected to the inner wall of the hydraulic pipe 53. A pushing round rod 56 is fixedly connected to the bottom of the piston block 55. One end of the pushing round rod 56 away from the piston block 55 is fixedly connected with a mounting bracket 57.

[0039] The scraping component 5 further includes a right-angled groove 58 formed in the side wall of the mounting bracket 57. A rotating plate 59 is rotatably connected to the inner wall of the right-angled groove 58. A second volute spring 510 is fixedly connected to the inner wall of the rotating plate 59. By utilizing the characteristic that the hydraulic telescopic tube 43 is compressed due to the lateral movement of the U-shaped sliding plate 45, a scraping component 5 is provided inside the device. When the hydraulic telescopic tube 43 is pressurized, the liquid inside the hydraulic telescopic tube 43 will enter the inside of the collection box 52. The solution inside the collection box 52 increases, forcing the piston block 55 to slide downward along the inner wall of the hydraulic tube 53. The downward-moving piston block 55 drives the mounting bracket 57 to move downward synchronously through the push rod 56. At this time, the downward-moving mounting bracket 57 drives the rotating plate 59 to move downward synchronously, so that the rotating plate 59 can scrape and clean the inner wall of the sludge discharge pipe 51, avoiding the accumulation and drying of impurities on the inner wall of the sludge discharge pipe 51, resulting in the blockage inside the sludge discharge pipe 51 and affecting the discharge efficiency of the device.

[0040] One end of the spring telescopic rod 37 away from the fixed block 36 is fixedly connected to the outer wall of the cylinder 1. The outer wall of the sliding disc 22 is slidably connected to the inner wall of the cylinder 1. The inner wall of the sliding disc 22 is slidably connected to the outer wall of the hexagonal tube 11. The outer wall of the piston plate 14 is slidably connected to the inner wall of the cylinder 1. The inner wall of the piston plate 14 is slidably connected to the outer wall of the hexagonal tube 11.

[0041] A specific application of this embodiment is as follows: Before use, the cylinder 1 is installed at the required position, and the sewage to be precipitated is put into the inside of the cylinder 1. Then the precipitation starts. After the sewage inside the cylinder 1 is stratified, the power supply of the electric telescopic rod 13 is turned on. The extended electric telescopic rod 13 drives the piston plate 14 to slide downward, so that the piston plate 14 is in contact with the inner wall of the cylinder 1, making a closed space formed by the top of the sliding disc 22, the outer wall of the hexagonal tube 11, the inner wall of the cylinder 1 and the bottom of the piston plate 14. As the electric telescopic rod 13 drives the piston plate 14 to slide downward, the downward pushing force of the piston plate 14 forces the sliding disc 22 to slide downward along the outer wall of the hexagonal tube 11 through the sewage. The downward-moving sliding disc 22 finally crosses the highest end of the first discharge port 24, making the inner wall of the first discharge port 24 and the top of the sliding disc 22 out of alignment, forming a gap. At this time, the sewage in the closed space is affected by high pressure and will force the sediment to enter the inside of the hexagonal tube 11 through the above gap. Through the application of the above components, when the device discharges the bottom sediment, the phenomenon of mixing of the sediment and the supernatant can be effectively reduced.

[0042] By utilizing the characteristic that the piston plate 14 slides downward when discharging the sediment, a drainage mechanism 3 is provided inside the device. When the piston plate 14 moves downward, the bottom of the piston plate 14 will contact the top of the contact plate 35 as shown in Figure 3At this state, the downward-moving piston plate 14 will push the sliding baffle 33 along the inner wall of the sliding groove 31 downward through the contact plate 35, causing the third discharge port 34 to move downward synchronously, so that a gap for outward discharge is formed between the third discharge port 34 and the second discharge port 32. At this time, the sediment at the bottom has been completely discharged outward through the first discharge port 24, and the supernatant remaining inside the cylinder 1 will be discharged outward through the gap between the third discharge port 34 and the second discharge port 32. At this time, the sealed space composed of the sliding disc 22, the hexagonal tube 11, the cylinder 1, and the piston plate 14 disappears, so that the force pushing the piston plate 14 downward cannot force the sliding disc 22 to move downward through the supernatant. The sliding disc 22 is reset under the push of the first spring 23. At this time, the bottom of the sliding disc 22 contacts the bottom of the contact plate 35, and the upward-moving sliding disc 22 will force the remaining supernatant to be discharged outward through the gap between the third discharge port 34 and the second discharge port 32. Through the application of the above components, the rapid recovery of the supernatant is realized.

[0043] Taking advantage of the characteristic that the above-mentioned sediment is discharged outward through the first discharge port 24, a separation component 4 is provided inside the device. When the impurity is sprayed into the hexagonal tube 11 through the first discharge port 24, the sprayed sediment will contact the outer wall of the U-shaped sliding plate 45, forcing the U-shaped sliding plate 45 to drive the scraper 46 to move towards the collection box 52. During this process, the sediment will pass through the filter screen 42 again. At this time, impurities with larger particles or flocs in the sediment will stay on the top of the filter screen 42; and every time the piston plate 14 slowly moves downward by a certain distance, the sliding disc 22 moves downward synchronously by a certain distance. After the downward-moving sliding disc 22 exceeds the first discharge port 24 by a certain distance, under the push of the first spring 23, while the sliding disc 22 is reset, the sliding disc 22 will cover the first discharge port 24, so that the sediment will no longer discharge impurities outward through the first discharge port 24. At this time, the pressure on the U-shaped sliding plate 45 decreases, and the second spring 44 releases pressure, causing the U-shaped sliding plate 45 to drive the scraper 46 to reset synchronously. During the reset process, the scraper 46 will rotate around the connection point, so that the impurities on the top of the filter screen 42 will not limit the reset of the scraper 46. When the piston plate 14 continues to move downward, the externally sprayed sediment will force the U-shaped sliding plate 45 to move outward again. When the outward-moving U-shaped sliding plate 45 drives the scraper 46 to move again, the side wall of the scraper 46 will contact the inner wall of the U-shaped sliding plate 45 synchronously, restricting the rotation of the scraper 46. At this time, the lateral movement of the scraper 46 will drive the large impurities and flocs on the top of the filter screen 42 to move laterally towards the discharge port 48, and finally the impurities on the top of the filter screen 42 will be discharged outward through the discharge port 48 and the slag discharge pipe 49 from the sludge discharge pipe 51. Through the application of the above components, when the sediment is discharged, the sludge and large impurities can be effectively separated.

[0044] Taking advantage of the characteristic that the above-mentioned hydraulic telescopic tube 43 is compressed by the lateral movement of the U-shaped sliding plate 45, a scraping component 5 is provided inside the device. When the hydraulic telescopic tube 43 is pressed, the liquid inside the hydraulic telescopic tube 43 will enter the inside of the collection box 52, and the solution inside the collection box 52 increases, forcing the piston block 55 to slide downward along the inner wall of the hydraulic tube 53. The downward-moving piston block 55 drives the mounting bracket 57 to move downward synchronously by pushing the round rod 56. At this time, the downward-moving mounting bracket 57 drives the rotating plate 59 to move downward synchronously, so that the rotating plate 59 can scrape and clean the inner wall of the sludge discharge pipe 51, avoiding the accumulation and drying of impurities on the inner wall of the sludge discharge pipe 51, resulting in blockage inside the sludge discharge pipe 51 and affecting the discharge efficiency of the device.
