Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a sewage treatment sedimentation separation device. Background Art

[0002] A sewage treatment sedimentation and separation unit is a key piece of equipment used to separate suspended solid impurities in the sewage treatment process. Its core principle is to use gravity to settle suspended solids in sewage, thereby achieving solid-liquid separation. The unit typically comprises functional areas such as an inlet, settling, outlet, and sludge zones. After sewage flows evenly from the inlet into the settling zone, suspended particles gradually sink to the bottom sludge zone under the action of gravity. The clarified sewage is then discharged through the outlet.

[0003] Chinese patent CN110975348B discloses a sedimentation tank and a sewage treatment device, wherein the sedimentation tank includes a tank body and a plurality of sedimentation pieces, wherein the plurality of sedimentation pieces are arranged in the tank body along the depth direction of the tank body and divide the internal space of the tank body into a plurality of water flow spaces; when the sedimentation piece is in a first position, the inclination angle of the sedimentation piece relative to the tank body is a first angle, so that the sediment mud in the sewage settles on the sedimentation piece when the sewage flows through the water flow space; when the sedimentation piece is in a second position, the inclination angle of the sedimentation piece relative to the tank body is a second angle, so that the sediment mud is separated from the sedimentation piece by gravity and falls to the bottom of the tank body; the plurality of sedimentation pieces constitute a sedimentation assembly; when the sedimentation piece is in the second position, one end of the sedimentation assembly protrudes from the surface of the sewage, and the other end of the sedimentation assembly abuts against the bottom inner wall of the tank body, so that the sedimentation assembly and the bottom inner wall of the tank body jointly constitute a blocking structure for blocking the sewage from flowing from one side of the sedimentation assembly to the other side of the sedimentation assembly in the tank body.

[0004] As shown in the above patent, the existing sewage treatment sedimentation and separation device divides the sedimentation tank into multiple water flow spaces by setting up multiple sedimentation pieces, so that the impurities in the sewage are flocculated and precipitated to the surface of the sedimentation piece under the action of the flocculant. When there is a lot of sedimentation mud, the sedimentation mud is caused to sink and discharged by rotating the sedimentation piece, thereby achieving the cleaning of the sedimentation mud on the surface of the sedimentation piece. However, if it only relies on the gravity of the sedimentation mud itself for cleaning, some sedimentation mud with higher viscosity will easily be adsorbed on the sedimentation piece with long-term use. Therefore, the sedimentation piece needs to be cleaned frequently, which is more troublesome to use. Moreover, in the process of the sedimentation piece rotating to discharge the sedimentation mud, in order to prevent the sedimentation mud from being discharged through the water outlet, the sewage treatment device needs to be stopped and restarted after cleaning, resulting in reduced sewage treatment efficiency.

[0005] Therefore, it is necessary to provide a sewage treatment sedimentation separation device to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 9, in the embodiments of the present invention, a sewage treatment sediment separation device includes a treatment tank 1, a plurality of water inlets 101 provided at the front end of the treatment tank 1, a water outlet 102 provided at the top of the rear end of the treatment tank 1, a sludge discharge chamber 104 and a sedimentation chamber 105 opened inside the treatment tank 1. A plurality of sedimentation chambers 105 are arranged from top to bottom. There are two sludge discharge chambers 104 which are respectively arranged on both sides of the sedimentation chamber 105. The bottom ends of the two sludge discharge chambers 104 are both communicated with a sludge discharge port 103, and the sludge discharge port 103 is communicated with a sludge collection device. An inlet chamber is provided between the side wall at the front end of the treatment tank 1 and the sedimentation chamber 105, and the inlet chamber is communicated with the plurality of water inlets 101. An outlet chamber is provided between the side wall at the rear end of the treatment tank 1 and the sedimentation chamber 105, and the outlet chamber is communicated with the water outlet 102. A scraper 5 is slidably arranged in the sedimentation chamber 105. Longitudinal partitions 2 are fixedly installed on both sides of the inner cavity of the treatment tank 1. A driving mechanism for driving the scraper 5 to horizontally move between the two longitudinal partitions 2 is arranged in the treatment tank 1. A plurality of sludge discharge holes 201 are opened on the longitudinal partition 2. The sediment sludge in the sedimentation chamber 105 is pushed by the scraper 5 and discharged into the sludge discharge chamber 104 through the sludge discharge holes 201. A valve assembly for closing the sludge discharge holes 201 is arranged in the sludge discharge chamber 104. The sedimentation chamber 105 is surrounded by two longitudinal partitions 2, a plurality of first transverse partitions 3, a second transverse partition 4 and a horizontal partition 26. The number of the first transverse partitions 3 and the second transverse partition 4 is the same as the number of the sedimentation chambers 105. The number of the horizontal partitions 26 is twice the number of the sedimentation chambers 105. The length of the longitudinal partition 2 is greater than the length of the horizontal partition 26 to form an inlet chamber and an outlet chamber on the front and rear sides of the sedimentation chamber 105. Specifically, a first transverse partition 3 and a second transverse partition 4 are respectively arranged at the front end and the rear end of the sedimentation chamber 105. Horizontal partitions 26 are arranged above and below the sedimentation chamber 105. The bottom wall of the scraper 5 is in contact with the horizontal partition 26. An inlet hole 301 is opened at the top position of the first transverse partition 3. A drainage hole 401 is opened at the top position of the second transverse partition 4. The inlet hole 301 is communicated with the inlet chamber. The drainage hole 401 is communicated with the outlet chamber; During specific use, the sewage added with a flocculant is input into the inlet chamber through the plurality of water inlets 101, and then enters the plurality of sedimentation chambers 105 through the plurality of inlet holes 301 and passes through the first transverse partition 3. Under the action of the flocculant, the impurities in the water gradually deposit at the bottom of the sedimentation chamber 105 in the form of sediment sludge. The clear water gradually drains into the outlet chamber through the drainage holes 401 on the second transverse partition 4, and then overflows through the water outlet 102 for discharge. As the sediment sludge accumulates in the sedimentation chamber 105, the driving mechanism drives the scraper 5 to horizontally reciprocate, so as to discharge the sediment sludge in the sedimentation chamber 105 into the sludge discharge chamber 104 through the sludge discharge holes 201, and then discharge it through the sludge discharge port 103.

[0022] In this embodiment, preferably, a driving plate 8 is fixedly installed on one side of the scraping plate 5 close to the first transverse partition plate 3. A chute 302 is formed at the bottom position of the first transverse partition plate 3. The driving plate 8 penetrates through the chute 302, and the driving plate 8 is slidably matched with the chute 302. The driving mechanism is in transmission connection with the driving plate 8. The driving mechanism includes a transmission box 10, a driving rod 9, a screw rod 12, a driving seat 13 and a motor 11. The driving rod 9 is arranged in the water inlet cavity. The driving rod 9 is fixedly connected with a plurality of driving plates 8. The transmission box 10 is fixedly installed on one side of the top of the treatment tank 1 close to the water inlet 101. The transmission box 10 is communicated with the water inlet cavity. The screw rod 12 is rotatably installed inside the transmission box 10. The top end of the driving rod 9 is fixedly installed with a driving seat 13. The screw rod 12 penetrates through the driving seat 13, and the screw rod 12 is in threaded connection with the driving seat 13. The motor 11 is fixedly installed on the side wall of the transmission box 10, and the output end of the motor 11 is fixedly connected with the end of the screw rod 12. The motor 11 can drive the screw rod 12 to rotate. When the screw rod 12 rotates, it drives the driving seat 13 to move horizontally. When the driving seat 13 moves horizontally, it drives a plurality of driving plates 8 to move horizontally through the driving rod 9, thereby driving a plurality of scraping plates 5 to move horizontally synchronously.

[0023] Please refer to Figures 3 to 7 and Figures 9 to 13In the embodiment of the present invention, in order to prevent the sediment mud from passing over the top of the scraper 5 when the scraper 5 slides, baffles 6 are rotatably installed on both sides of the top of the scraper 5 through hinges 7. In order to prevent the baffle 6 from always maintaining a horizontal state and causing the sediment mud to be deposited on the upper surface of the baffle 6, an adjusting component for driving the baffle 6 to rotate is provided inside the scraper 5. The rotation angle of the baffle 6 is 0°-90°. Specifically, the adjusting component includes a push plate 14, a connecting shaft 15 and a transmission component for driving the connecting shaft 15 to rotate. The top of the scraper 5 is opened There is a mounting groove 501, and the push plate 14 is rotatably mounted inside the mounting groove 501 through a connecting shaft 15, and the connecting shaft 15 is fixedly connected to the end of the push plate 14; the transmission assembly includes a gear 16 fixedly sleeved on the connecting shaft 15, a rack 17 meshing with the gear 16, and a horizontal adjustment rod 18 slidably mounted inside the scraper 5, and the scraper 5 is provided with a mounting cavity 502 inside, and the gear 16 and the rack 17 are both arranged in the mounting cavity 502, one end of the horizontal adjustment rod 18 is fixedly connected to the rack 17, and the horizontal adjustment rod 18 is fixedly connected to the rack 17. The other end of 8 penetrates the side wall of the scraper 5 to extend from the inside of the scraper 5; when the horizontal adjustment rod 18 moves, it can drive the rack 17 to move, and when the rack 17 moves, it drives the gear 16 to rotate, thereby driving the push plate 14 to rotate through the connecting shaft 15. The push plate 14 has three states. One is when the scraper 5 is not working, the push plate 14 is completely retracted in the mounting groove 501. At this time, the two baffles 6 are in a vertical state, and the sediment sludge settled in the sewage will not fall on the baffle 6. The second is that the push plate 14 rotates to the right. At this time, the baffle 6 on the right is pushed open by the push plate 14. In a horizontal state, as the scraper 5 moves to the right, the sedimentation mud is pushed into the mud discharge cavity 104 on the right through the mud discharge hole 201 by the right movement of the scraper 5. Thirdly, the push plate 14 rotates to the left. At this time, the baffle 6 on the left is pushed open by the push plate 14 and is in a horizontal state. As the scraper 5 moves to the left, the sedimentation mud is pushed into the mud discharge cavity 104 on the left through the mud discharge hole 201 by the left movement of the scraper 5, so that the two baffles 6 rotate adaptively according to the moving direction of the scraper 5 to prevent the sedimentation mud from crossing the scraper 5 and causing a decrease in the mud scraping efficiency.

[0024] Through the setting of the driving mechanism and the scraper 5, combined with the structure of the baffle 6 that can be adaptively adjusted, the efficient cleaning and continuous treatment of sediment sludge are realized. Specifically, the driving mechanism drives the scraper 5 to reciprocate horizontally in the sedimentation chamber 105, replacing the traditional rotary dredging method, effectively scraping off the adhesive sediment sludge and avoiding residues. The adjusting assembly cooperates with the gear 16 and the rack 17 to drive the two baffles 6 to automatically switch to the horizontal state along with the moving direction of the scraper 5, which not only prevents the sediment sludge from flowing back over the scraper 5, but also avoids the problem of sediment accumulation on the baffle 6, and can also prevent the sediment sludge from floating up during the cleaning of the sediment sludge. At the same time, the setting of the sludge discharge hole 201 and the valve assembly, combined with the diversion structure of the two-side sludge discharge chambers 104, enables the dredging process to be completed without stopping the machine, ensuring the continuous operation of the sewage treatment system, significantly improving the treatment efficiency and reducing the maintenance frequency.

[0025] In this embodiment, preferably, a vertical adjusting rod 20 is arranged in the water inlet chamber. The vertical adjusting rod 20 is parallel to the driving rod 9. The horizontal adjusting rod 18 penetrates through the driving plate 8, and the horizontal adjusting rod 18 is slidably matched with the driving plate 8. The ends of the plurality of horizontal adjusting rods 18 are fixedly connected to the vertical adjusting rod 20. A connecting seat 21 is fixedly installed at the top end of the vertical adjusting rod 20. A hydraulic cylinder 22 is fixedly installed on the driving seat 13. The output end of the hydraulic cylinder 22 is fixedly connected to the connecting seat 21. By the telescopic movement of the output end of the hydraulic cylinder 22, the connecting seat 21 can be driven to move, thereby driving the vertical adjusting rod 20 to move away from or close to the driving rod 9. When the vertical adjusting rod 20 moves, it drives the horizontal adjusting rod 18 to move, thereby driving the rack 17 to move. When the rack 17 moves, it drives the gear 16 to rotate, and thus drives the push plate 14 to rotate through the connecting shaft 15.

[0026] In this embodiment, preferably, magnetic blocks 19 are embedded on both sides of the scraper 5. The magnetic blocks 19 are magnetically attracted to the baffle 6. The setting of the magnetic blocks 19 enables the baffle 6 to rotate downward to fit with the scraper 5 under the magnetic attraction of the magnetic blocks 19 when the baffle 6 does not contact the push plate 14. When the baffle 6 is in contact with the scraper 5, the sediment sludge remaining between the baffle 6 and the scraper 5 is extruded, so that the two side walls of the scraper 5 and the side wall of the baffle 6 close to the scraper 5 can be cleaned, preventing the attachment of some sediment sludge that is difficult to fall off on the scraper 5 and the baffle 6, resulting in a reduction in the cleaning efficiency.

[0027] In this embodiment, preferably, the valve assembly includes a sealing plate 23 and an elastic connecting member. The sealing plate 23 is disposed in the sludge discharge chamber 104. The sealing plate 23 is elastically connected to the inner wall of the treatment tank 1 through a plurality of elastic connecting members. A plurality of sealing gaskets 2301 are fixedly provided on a side of the sealing plate 23 away from the elastic connecting members. When the sealing gaskets 2301 are in contact with the sludge discharge holes 201, the sludge discharge holes 201 are closed. The sealing gaskets 2301 are made of rubber material. The elastic connecting member includes a connecting cylinder 24 and a connecting column 25. The connecting cylinder 24 is fixedly connected to the inner wall of the treatment tank 1. One end of the connecting column 25 is fixedly connected to the sealing plate 23. The other end of the connecting column 25 extends into the connecting cylinder 24, and the connecting column 25 is slidably engaged with the connecting cylinder 24. A spring (not shown in the figure) is disposed in the connecting cylinder 24. One end of the spring is fixedly connected to the connecting column 25, and the other end of the spring is fixedly connected to the inner side wall of the connecting cylinder 24. Under the elastic action of the spring, the sealing plate 23 is pressed against the longitudinal partition plate 2, so that the sealing gaskets 2301 close the sludge discharge holes 201 to prevent water flow from flowing into the sludge discharge chamber 104 through the sludge discharge holes 201. When the scraper 5 moves to clean the precipitated sludge, the push plate 14 rotates to a state perpendicular to the scraper 5. At this time, the end of the push plate 14 extends out from below the baffle 6. As the scraper 5 drives the push plate 14 to move horizontally, the scraper 5 first contacts the sealing gasket 2301, thereby pushing the sealing gasket 2301 and the sealing plate 23 to move away from the longitudinal partition plate 2, and further opening the sludge discharge holes 201, so that the precipitated sludge below the baffle 6 falls downward into the precipitation chamber 105, thereby realizing the transfer of the precipitated sludge in the precipitation chamber 105 to the sludge discharge chamber 104. Through the arrangement of a whole large-area sealing plate 23, when the sludge discharge port 103 is closed, the sealing plate 23 can be pressed against the longitudinal partition plate 2, thereby squeezing the precipitated sludge between the longitudinal partition plate 2 and the sealing plate 23, so that some of the precipitated sludge attached to the longitudinal partition plate 2 and the sealing plate 23 can be extruded and fall downward, which can effectively prevent the precipitated sludge from remaining in the sludge discharge chamber 104 and causing blockage of the sludge discharge chamber 104.

[0028] The above is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
