[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a high-performance pulse clarifier. Figure 1 The high-performance pulse clarifier includes a tank body 1 and a plurality of inclined tubes 2 installed in the tank body 1. The plurality of inclined tubes 2 are connected to form a honeycomb tube row. The angle between the inclined tube 2 and the horizontal plane is 60°. The cross-section of the inclined tube 2 is a polygon. In the embodiment of the present application, the cross-section of the inclined tube 2 is a hexagon. The plurality of inclined tubes 2 are located between the sludge layer and the clear water layer in the tank body 1.

[0024] Reference Figure 1 and Figure 2 An annular scraper 3 is slidably arranged in the inclined tube 2, the sliding direction of the annular scraper 3 is parallel to the length direction of the inclined tube 2, the annular scraper 3 is made of corrosion-resistant metal sheet, the length direction of the inclined tube 2 is perpendicular to the plane where the annular scraper 3 is located, the outer wall of the annular scraper 3 abuts against the inner wall of the inclined tube 2, so that the cross section of the annular scraper 3 is a hexagonal ring; an adsorption layer 4 is fixedly connected to the annular scraper 3, and the adsorption layer 4 is an activated carbon layer, which effectively adsorbs micro-pollutants; a sliding component for driving the annular scraper 3 to slide back and forth is arranged in the inclined tube 2.

[0025] When in use, the annular scraper 3 is driven by the sliding component to slide back and forth along the length direction of the inclined tube 2. The annular scraper 3 can scrape off impurities attached to the inner wall of the inclined tube 2. The scraped impurities will not flow to the clean water layer due to the obstruction of the adsorption layer 4, and the impurities gathered on the annular scraper 3 will fall into the sludge layer along the inclined inner wall of the inclined tube 2, which ensures the cleanliness of the inclined tube 2 to a certain extent and helps to improve the water quality of the effluent. At the same time, the adsorption layer 4 can adsorb the clarified water passing through the inclined tube 2, efficiently remove micro-pollutants in the raw water, and further ensure the water quality of the effluent.

[0026] Reference Figure 2 and Figure 3 In order to facilitate driving the annular scraper 3 to slide back and forth along the corresponding inclined tube 2, a support rod 13 is fixed in the inclined tube 2, and the support rod 13 is located at one end of the inclined tube 2 close to the clean water layer. The cross section of the support rod 13 is smaller than the cross section of the inclined tube 2. The sliding assembly includes a reciprocating screw 5 and a rotating member. The reciprocating screw 5 is rotatably set on the support rod 13, and the reciprocating screw 5 extends in the direction close to the sludge layer. The rotation axis of the reciprocating screw 5 is parallel to the length direction of the inclined tube 2, and the reciprocating screw 5 is located at the center of the inclined tube 2; the adsorption layer 4 is annular, and a mounting block 14 is fixed in the adsorption layer 4, that is, the adsorption layer 4 is located between the mounting block 14 and the annular scraper 3, and the mounting block 14 is threadedly sleeved on the corresponding reciprocating screw 5, and the rotating member is set on the support rod 13, and the rotating member is used to drive the reciprocating screw 5 to rotate.

[0027] Reference Figure 2 and Figure 3 In order to facilitate the driving of the reciprocating screw 5 to rotate, the rotating part includes an impeller 6, which is rotatably arranged on the support rod 13. The reciprocating screw 5 is coaxially connected with the corresponding impeller 6. The impeller 6 is located on the side of the annular scraper 3 close to the clean water layer, which helps to ensure the cleanliness of the impeller 6.

[0028] When in use, the clarified water that continuously flows upward through the sludge layer enters the inclined tube 2. The clarified water that flows upward will drive the impeller 6 in the corresponding inclined tube 2 to rotate. The rotation of the impeller 6, on the one hand, stirs the clarified water, increases the turbulence of the clarified water, reduces the thickness of the dead water layer of the clarified water, and makes it difficult for biological growth to occur in the water collection tank; on the other hand, the rotating impeller 6 will drive the reciprocating screw 5 to rotate. Since the annular scraper 3 abuts against the inner wall of the inclined tube 2, the limiting mounting block 14 rotates with the reciprocating screw 5, so that the reciprocating screw 5 drives the corresponding mounting block 14 to slide back and forth along the reciprocating screw 5, so that the annular scraper 3 can slide back and forth along the length direction of the inclined tube 2, which helps the annular scraper 3 to scrape off the impurities attached to the inner wall of the inclined tube 2, ensures the cleanliness of the inclined tube 2 to a certain extent, and helps to improve the quality of the effluent water. By utilizing the impact force of the clarified water continuously flowing upward to drive the impeller 6 to rotate, there is no need to set up a separate driving source, which helps to save costs.

[0029] Reference Figure 2 and Figure 3 An accordion cover 12 is fixed on opposite sides of the mounting block 14. The accordion cover 12 extends along the length direction of the reciprocating screw 5. The movable cover of the accordion cover 12 is arranged on the reciprocating screw 5 on the corresponding side. The end of the accordion cover 12 away from the mounting block 14 is fixed to the end of the corresponding side of the reciprocating screw 5. The accordion cover 12 is made of corrosion-resistant plastic.

[0030] When the mounting block 14 slides along the reciprocating screw 5, the mounting block 14 will stretch or compress the accordion cover 12 on both sides. Since the accordion cover 12 is extensible and can be deformed along with the sliding of the mounting block 14, the reciprocating screw 5 can be protected, and impurities are not easily accumulated on the reciprocating screw 5, thereby ensuring the threaded fit between the mounting block 14 and the reciprocating screw 5.

[0031] Reference Figure 2 and Figure 3 An elastic movable scraper 7 is fixed to one side of the annular scraper 3 close to the sludge layer, and the elastic movable scraper 7 corresponds to the side wall of the annular scraper 3 one by one, so that the elastic movable scraper 7 is arranged along the circumference of the annular scraper 3, and the adjacent elastic movable scraper blades 7 abut against each other, and the end of the elastic movable scraper 7 abuts against the inner wall of the inclined tube 2. The elastic movable scraper 7 is inclined, and the distance from the elastic movable scraper 7 to the side of the annular scraper 3 close to the sludge layer gradually increases toward the direction close to the adsorption layer 4. In the embodiment of the present application, the angle between the side of the elastic movable scraper 7 close to the clear water layer and the side of the annular scraper 3 close to the sludge layer is 45°; so that the impurities scraped off by the elastic movable scraper 7 are not easy to adhere to the adsorption layer 4; an elastic member is arranged between the annular scraper 3 and the elastic movable scraper 7, and an abutment member for abutting the vibration of the elastic movable scraper 7 is arranged at one end of the inclined tube 2 close to the sludge layer.

[0032] Reference Figure 2 and Figure 3 The elastic member includes a V-shaped elastic sheet 8 for resetting the elastic movable scraper 7. One end of the V-shaped elastic sheet 8 is fixed to the side of the annular scraper 3 close to the sludge layer, and the other end is fixed to the side of the elastic movable scraper 7 close to the annular scraper 3. The opening of the V-shaped elastic sheet 8 is arranged toward the clean water layer. In other embodiments, the elastic member can be replaced by a spring, an elastic plastic ball, etc. Since the V-shaped elastic sheet 8 has the performance of deforming and resetting, it can meet the situation that the elastic movable scraper 7 deforms toward the side close to the annular scraper 3 and then gradually resets.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the deformation of the elastic movable scraper 7, the abutment part includes an abutment rod 9, which is fixedly arranged on the inner wall of the inclined tube 2 close to the sludge layer. There is an abutment rod 9 on each side of the inner wall of the inclined tube 2. The abutment rod 9 is located in the middle of the corresponding inner wall. The abutment rod 9 extends in the direction away from the sludge layer, and the end of the abutment rod 9 away from the sludge layer is inclined toward the center of the inclined tube 2. An elastic ball 15 is fixed on the side of the abutment rod 9 away from the sludge layer. The elastic ball 15 is used to abut with the corresponding elastic movable scraper 7.

[0034] When the mounting block 14 drives the annular scraper 3 and the elastic movable scraper 7 to slide in the direction close to the sludge layer, the elastic movable scraper 7 gradually approaches the abutment rod 9, and then the elastic ball 15 on the abutment rod 9 abuts against the elastic movable scraper 7. As the mounting block 14 continues to approach the sludge layer, the elastic ball 15 on the abutment rod 9 will slide relative to the elastic movable scraper 7 on the corresponding side, and push the elastic movable scraper 7 to deform in the direction close to the annular scraper 3, compressing the V-shaped elastic sheet 8. At this time, the impurities gathered on the elastic movable scraper 7 will be separated from the elastic movable scraper 7, making it convenient for the impurities to fall back into the sludge layer; and the abutment rod 9 is inclined, so that the impurities are more easily gathered along the abutment rod 9 at the lower edge of the inclined tube 2, providing convenience for the impurities to fall into the sludge layer. Then the mounting block 14 drives the annular scraper 3 to slide in the direction away from the sludge layer, so that the elastic movable scraper 7 is separated from the abutment rod 9. Since the V-shaped elastic sheet 8 has elastic potential energy to restore deformation, it will drive the elastic movable scraper 7 to vibrate back and forth, further facilitating the falling of impurities on the elastic movable scraper 7, ensuring the cleanliness of the inclined tube 2, and helping to improve the water quality of the outlet water.

[0035] Reference Figure 3 and Figure 4 A ductile abutment filament 10 is provided on one side of the annular scraper 3 close to the inner wall of the inclined tube 2. The abutment filament 10 can be a plastic wire or a metal wire, which is not limited here; the abutment filament 10 corresponds one-to-one with the side wall of the annular scraper 3, and the two ends of the abutment filament 10 are fixed on the corresponding side wall of the annular scraper 3, and the abutment filament 10 is in a tensioned state, and the abutment filament 10 abuts against the inner wall of the corresponding side of the inclined tube 2. A pressure sensor 11 is embedded on the outer wall of each side of the annular scraper 3, and the pressure sensor 11 corresponds one-to-one with the corresponding abutment filament 10, and the abutment filament 10 abuts against the corresponding pressure sensor 11. The pressure sensor 11 is used to wirelessly connect to an external controller, and the pressure sensor 11 detects the abutment pressure of the abutment filament 10 and sends it to the external controller.

[0036] When the mounting block 14 drives the annular scraper 3 to slide along the length direction of the inclined tube 2, the abutting filament 10 abuts against the inner wall of the inclined tube 2. On the one hand, the inner wall of the inclined tube 2 is cleaned. On the other hand, when cracks appear on the inner wall of the inclined tube 2, the abutting filament 10 sliding relative to the inner wall of the inclined tube 2 is easily embedded in the cracks or hooked on the edge of the cracks, thereby deforming the abutting filament 10. The deformation of the abutting filament 10 will cause the displacement of the abutting filament 10 and the pressure sensor 11, and the abutting pressure of the pressure sensor 11 will change. If the abutting pressure received by the external controller exceeds the preset range, it proves that cracks appear on the inner wall of the inclined tube 2, which makes it easy for external personnel to judge whether cracks appear in the inclined tube 2, and to carry out subsequent processing in time to maintain the high-performance operation state of the equipment.

[0037] The implementation principle of the embodiment of the present application is as follows: when in use, the mounting block 14 is in the initial state, that is, the mounting block 14 is located at one end of the reciprocating screw 5 close to the impeller 6; the raw water continuously flows upward through the sludge layer, and the clarified water passing through the sludge layer enters the inclined tube 2, which will push the impeller 6 in the corresponding inclined tube 2 to rotate. The rotation of the impeller 6, on the one hand, stirs the clarified water, improves the turbulence of the clarified water, and is less likely to cause biological breeding; on the other hand, the rotation of the impeller 6 will drive the reciprocating screw 5 to rotate, and the reciprocating screw 5 drives the corresponding mounting block 14 to slide along the reciprocating screw 5 toward the direction close to the sludge layer, so that the elastic movable scraper 7 and the abutting filament 10 scrape the inner wall of the inclined tube 2, which helps to scrape off the impurities attached to the inner wall of the inclined tube 2 and accelerate the sedimentation speed; then the abutting rod 9 gradually abuts against the corresponding elastic movable scraper 7, and as the mounting block 14 continues to approach the sludge layer, the abutting filament 10 The elastic ball 15 on the connecting rod 9 will slide relative to the elastic movable scraper 7 on the corresponding side, and push the elastic movable scraper 7 to deform. At the same time, the impurities gathered on the elastic movable scraper 7 will be separated from the elastic movable scraper 7, making it convenient for the impurities to fall back into the sludge layer. Then the mounting block 14 moves to the end of the reciprocating screw 5 close to the sludge layer. As the reciprocating screw 5 continues to rotate in the same direction, the mounting block 14 drives the annular scraper 3 to slide in the direction away from the sludge layer, so that the elastic movable scraper 7 is separated from the abutting rod 9. Since the V-shaped elastic sheet 8 has elastic potential energy for restoring deformation, it will drive the elastic movable scraper 7 to vibrate back and forth, further facilitating the falling of impurities on the elastic movable scraper 7. In this reciprocating motion, the inner wall of the inclined tube 2 can be continuously cleaned during the operation of the clarification tank, which ensures the cleanliness of the inclined tube 2 to a certain extent and helps to improve the water quality of the effluent.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
