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

The sludge discharge chamber 104 is provided with a valve assembly for closing the sludge discharge hole 201. The sedimentation chamber 105 is composed of two longitudinal partitions 2, multiple first transverse partitions 3, second transverse partitions 4 and horizontal partitions 26. The number of the first transverse partitions 3 and the second transverse partitions 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. , so as to form a water inlet chamber and a water 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 provided at the front and rear ends of the sedimentation chamber 105. Horizontal partitions 26 are provided above and below the sedimentation chamber 105. The bottom wall of the scraper 5 is in contact with the horizontal partition 26.

Under the action of the flocculant, impurities in the water are gradually deposited at the bottom of the sedimentation chamber 105 in the form of sludge, and the clean water is gradually discharged into the water 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 sludge accumulates in the sedimentation chamber 105, the scraper 5 is driven to move horizontally back and forth by the driving mechanism, so that the sludge in the sedimentation chamber 105 is discharged into the sludge discharge chamber 104 through the sludge discharge hole 201, and then discharged through the sludge discharge port 103.

[0035] In this embodiment, preferably, a drive plate 8 is fixedly installed on one side of the scraper 5 close to the first transverse partition 3, a slide groove 302 is provided at the bottom position of the first transverse partition 3, the drive plate 8 passes through the slide groove 302, and the drive plate 8 slides with the slide groove 302, and the drive mechanism is connected to the drive plate 8 by transmission; the drive mechanism includes a transmission box 10, a drive rod 9, a screw 12, a drive seat 13 and a motor 11, the drive rod 9 is arranged in the water inlet chamber, the drive rod 9 is fixedly connected to multiple drive plates 8, the transmission box 10 is fixedly installed on the top of the treatment box 1 near the water inlet 101 side, The transmission box 10 is communicated with the water inlet chamber, and the screw 12 is rotatably installed inside the transmission box 10. A drive seat 13 is fixedly installed on the top of the drive rod 9. The screw 12 passes through the drive seat 13, and the screw 12 is threadedly connected to the drive 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 to the end of the screw 12; the motor 11 can drive the screw 12 to rotate, and when the screw 12 rotates, it drives the drive seat 13 to move horizontally. When the drive seat 13 moves horizontally, the drive rod 9 drives multiple drive plates 8 to move horizontally, thereby driving multiple scrapers 5 to move horizontally synchronously.

[0036] See also 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.

[0037] The present invention realizes efficient cleaning and continuous treatment of sediment sludge through the setting of the driving mechanism and the scraper 5, combined with the adaptively adjustable baffle 6 structure. Specifically, the scraper 5 is driven by the driving mechanism to move back and forth horizontally in the sedimentation chamber 105, replacing the traditional rotary dredging method, effectively scraping off the adhesive sediment sludge and avoiding residue; the adjustment component cooperates with the gear 16 and rack 17 to transmit, so that the two baffles 6 automatically switch to the horizontal state 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 mud accumulation on the baffle 6, and can also avoid the sediment sludge from floating when cleaning the sediment sludge. At the same time, the setting of the mud discharge hole 201 and the valve assembly, combined with the diversion structure of the mud discharge chamber 104 on both sides, enables the dredging process to be completed without stopping, thereby ensuring the continuous operation of the sewage treatment system, significantly improving the treatment efficiency and reducing the maintenance frequency.

[0038] In this embodiment, preferably, a vertical adjustment rod 20 is provided in the water inlet chamber, and the vertical adjustment rod 20 is parallel to the driving rod 9. The horizontal adjustment rod 18 passes through the driving plate 8, and the horizontal adjustment rod 18 slides with the driving plate 8. The ends of the multiple horizontal adjustment rods 18 are fixedly connected to the vertical adjustment rod 20. The top of the vertical adjustment rod 20 is fixedly installed with a connecting seat 21, and 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; the connecting seat 21 can be driven to move by the extension and contraction of the output end of the hydraulic cylinder 22, thereby driving the vertical adjustment rod 20 to move in the direction away from or close to the driving rod 9. When the vertical adjustment rod 20 moves, it drives the horizontal adjustment rod 18 to move, thereby driving the rack 17 to move. 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.

[0039] In this embodiment, preferably, magnetic blocks 19 are embedded and installed on both sides of the scraper 5, and 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 under the magnetic attraction of the magnetic blocks 19 until it is in contact with the scraper 5 when the baffle 6 is not in contact with the push plate 14. When the baffle 6 is in contact with the scraper 5, the sediment residue between the baffle 6 and the scraper 5 is squeezed out, so that the two side walls of the scraper 5 and the side walls of the baffle 6 close to the scraper 5 can be cleaned, preventing some sediment that is difficult to fall off from the scraper 5 and the baffle 6 from being attached to the scraper 5 and reducing the cleaning efficiency.

[0040] In this embodiment, preferably, the valve assembly includes a sealing plate 23 and an elastic connector. The sealing plate 23 is arranged in the mud discharge chamber 104. The sealing plate 23 is elastically connected to the box wall of the processing box 1 through multiple elastic connectors. A plurality of sealing gaskets 2301 are fixedly provided on the side of the sealing plate 23 away from the elastic connector. When the sealing gasket 2301 is in contact with the mud discharge hole 201, the mud discharge hole 201 is closed. The sealing gasket 2301 is made of rubber; the elastic connector includes a connecting tube 24 and a connecting column 25. The connecting tube 24 is fixedly connected to the wall of the treatment box 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 tube 24, and the connecting column 25 and the connecting tube 24 are slidably matched. A spring (not shown in the figure) is provided in the connecting tube 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 wall of the connecting tube 24; under the elastic action of the spring, the sealing plate 23 is pressed on the longitudinal partition 2, so that the sealing gasket 2301 will discharge mud The hole 201 is closed to prevent water from flowing into the mud discharge chamber 104 through the mud discharge hole 201. When the scraper 5 moves to clean the sediment, the push plate 14 rotates to a state perpendicular to the scraper 5. At this time, the end of the push plate 14 extends from the bottom of 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 2, thereby opening the mud discharge hole 201, thereby allowing the sediment below the baffle 6 to The mud falls downward into the sedimentation chamber 105, thereby transferring the sedimentation mud in the sedimentation chamber 105 to the mud discharge chamber 104. By setting a whole large-area sealing plate 23, when the mud discharge port 103 is closed, the sealing plate 23 can be pressed on the longitudinal partition 2, thereby squeezing the sedimentation mud between the longitudinal partition 2 and the sealing plate 23, so that some sedimentation mud attached to the longitudinal partition 2 and the sealing plate 23 can be squeezed out and fall downward, which can effectively prevent the sedimentation mud from remaining in the mud discharge chamber 104 and causing the mud discharge chamber 104 to be blocked.

[0041] The above description is only a preferred embodiment of the present invention.
