Description

Technical Field

[0001] This application relates to the field of sludge cleaning devices, and more particularly to a sludge cleaning device for a horizontal sedimentation tank in a waterworks. Background Technology

[0002] Water treatment involves multiple processes, including raw water mixing, flocculation, sedimentation, filtration, and disinfection. Sedimentation requires the use of a sedimentation tank to physically separate the sludge from the clean water. After sedimentation, the upper layer of clean water is drained away, and then the sludge that has settled at the bottom of the tank is scraped off. The scraped sludge is then pumped away by a sewage pump.

[0003] Existing sludge cleaning devices often encounter difficulties when cleaning sludge, as it accumulates at the bottom of the sedimentation tank, resulting in significant scraping resistance and hindering the smooth operation of the scraper blades. To address this, patent application CN202222704389.0 discloses a sludge cleaning device for a horizontal flow sedimentation tank in a waterworks. This device includes a sedimentation tank body, with a sedimentation trough fixedly connected to the inner bottom wall of the tank body. A fixing frame is fixedly connected to the top of the sedimentation tank body, and a drive motor is fixedly connected to the inner top wall of the fixing frame. A rope roller is fixedly connected to the output end of the drive motor, and the outer surface of the rope roller is fixedly connected to… The sedimentation tank has a steel wire rope, the free end of which passes over a rope roller and is fixedly connected to a sludge removal bucket. A flow guide frame and a conveyor belt are fixedly connected to the top of the sedimentation tank, with the flow guide frame located between the fixed frame and the conveyor belt. An inlet pipe is fixedly connected to the top of the sedimentation tank, and an outlet pipe is fixedly connected to one side of the sedimentation tank. A sludge scraping assembly is provided on the outer surface of the sedimentation tank. This assembly can scoop up the sludge from the bottom wall of the sedimentation tank and send it into the sedimentation trough, thus preventing the sludge from hardening due to prolonged storage and improving the sludge removal effect.

[0004] Although the above-mentioned sludge cleaning device can shovel up the sludge and send it into the sedimentation tank, it still has certain drawbacks in the long-term use. The bottom wall of the sedimentation tank is only scraped by the sludge scraper, and a small amount of sludge will still remain. Moreover, the sludge scraper will stick to the sludge during the long-term scraping process, which will affect the effect of repeated scraping. Therefore, this application proposes a sludge cleaning device for the horizontal flow sedimentation tank of a waterworks. Summary of the Invention

[0005] The purpose of this application is to address the technical problems pointed out in the background art by proposing a sludge cleaning device for a horizontal sedimentation tank in a waterworks.

[0006] The technical solution of this application is: a sludge cleaning device for a horizontal sedimentation tank in a waterworks, comprising a sedimentation tank body, a sludge collection seat provided on the bottom wall of the sedimentation tank body, the sludge collection seat and the two side walls of the sedimentation tank body forming a sludge collection area, the sludge collection seat being trapezoidal, and a scraper and a brush provided on the upper end of the sludge collection seat, the upper ends of the scraper and the brush being connected to a rectangular cylinder, and a transmission mechanism for driving the two rectangular cylinders being provided on the upper end of the sedimentation tank body;

[0007] The rectangular tube is equipped with an interlaced transmission mechanism that controls the relative sliding of the scraper and the brush, which works together to scrape and brush the sludge.

[0008] The sedimentation tank is equipped with a water control device located directly above the sludge collection seat on the upper inner wall. A spray washing mechanism is installed at the bottom of the water control device. A transmission component is provided on the outside of the water control device to control the inflow and outflow of water inside the water control device. The transmission component is driven by a transmission mechanism.

[0009] Preferably, the water control component includes a water storage cylinder and a piston that is slidably disposed inside the water storage cylinder, and one end of the water storage cylinder is connected to a water suction pipe.

[0010] Preferably, the spraying mechanism includes a water outlet pipe installed at the bottom of the water storage tank, and a plurality of nozzles are connected to the lower surface of the water outlet pipe. The end of the water outlet pipe near the water suction pipe is connected to the water storage tank through a connecting pipe.

[0011] The connecting pipe is equipped with a first one-way valve, and the suction pipe is equipped with a second one-way valve.

[0012] Preferably, the transmission mechanism includes a pair of lead screws rotatably connected to the inner wall of the sedimentation tank, sleeve blocks are sleeved on the side walls of the two lead screws, a protective cover is fixedly connected to the inner wall of the sedimentation tank covering the outside of the lead screws, the two sleeve blocks are slidably connected to the two protective covers respectively, the two lead screws are driven by a pulley assembly, and one of the lead screws is driven by a servo motor.

[0013] Preferably, the transmission assembly includes a magnetic ring slidably sleeved on the outer wall of the water storage cylinder, a magnetic block that attracts the magnetic ring is fixedly connected to one end of the piston, and connecting rods are fixedly connected to both ends of the magnetic ring, with the two connecting rods respectively fixedly connected to the two sleeve blocks;

[0014] The magnetic ring is inverted U-shaped, which can prevent the spraying mechanism from sliding on the outside of the water storage tank.

[0015] Preferably, each of the connecting rods has a contact rod fixedly connected to both sides, and the inner walls of both sides of the sedimentation tank are provided with a first touch switch that is at the same horizontal line as the two contact rods.

[0016] Preferably, the interleaved transmission mechanism includes a first rack and a second rack that slide through the lower surface of the rectangular tube. The bottom ends of the first rack and the second rack are fixedly connected to the scraper and the brush plate, respectively. The first rack and the second rack are driven by a transmission component.

[0017] A transmission block is fixedly connected to the side of the first rack, and a hydraulic cylinder for controlling the lifting and lowering of the transmission block is installed on the inner wall of the top of the rectangular tube.

[0018] The transmission component includes a rotating shaft rotatably connected to the inner wall of a rectangular tube, and a gear that meshes with a first rack and a second rack is fixedly sleeved on the side wall of the rotating shaft.

[0019] Preferably, the inner wall of the sedimentation tank is connected to a sludge cleaning rod located on one side of the sludge collection seat. The sludge cleaning rod is slightly higher than the scraper. When the scraper moves to one side of the sludge collection seat, the scraper moves upward and scrapes off the sludge stuck to the side wall of the scraper through the sludge cleaning rod.

[0020] Preferably, a base is connected to the middle of the bottom of the sedimentation tank, a drain pipe is connected to the side of the sedimentation tank, a valve is installed on the drain pipe, and a pair of sludge discharge pipes located below the two sludge collection areas are connected to the bottom of the sedimentation tank. Both sludge discharge pipes are connected to an external sludge pump.

[0021] Preferably, the system also includes a controller, with both first touch switches electrically connected to the controller, which is electrically connected to the mud pump, hydraulic cylinder, and servo motor.

[0022] Compared with the prior art, this application has the following beneficial technical effects:

[0023] This application sets up a scraper and a brush, with the bottom ends of the scraper and the brush set relatively far apart. Under the transmission mechanism, the scraper is driven to move to one side at the upper end of the sludge collection seat, thereby pushing the sludge at the upper end of the sludge collection seat to the corresponding sludge collection area. At this time, one of the contact rods will touch the corresponding first contact switch, thereby activating the hydraulic cylinder, causing the scraper to move upward and the brush to move downward. The scraper and the cleaning rod move relative to each other, and the cleaning rod scrapes the sludge on the side of the scraper into the sludge collection area, ensuring the scraping effect of the scraper in the next scraping.

[0024] By setting up water control components and transmission components, the piston is driven to one side by the transmission mechanism, and water is drawn into the water storage tank through the suction pipe. When the transmission mechanism drives the brush plate to move back, the piston will be driven back by the transmission component, thereby squeezing the water in the water storage tank into the water outlet pipe, and then spraying it out through several nozzles. During the brush plate's return movement, the sludge collection seat is washed, which improves the sludge cleaning effect.

[0025] In summary, this application, by setting up an interlaced transmission mechanism and scraper, in conjunction with the sludge cleaning rod, can clean the sludge on the side of the scraper after scraping, preventing sludge residue from remaining on the side of the scraper; by setting up a brush plate and water control device, during the reversal of the rectangular cylinder, the water inside the water storage tank can be squeezed to the top of the sludge collection seat through the spray washing mechanism, and with the cooperation of the brush plate, the sludge collection seat after scraping is washed, making the sludge deposited on the upper surface of the sludge collection seat cleaner.

[0045] Example

[0046] like Figure 1-7As shown, this application discloses a sludge cleaning device for a horizontal flow sedimentation tank in a waterworks. The device includes a sedimentation tank body 1, with a sludge collection seat 5 installed on the bottom wall of the sedimentation tank body 1. The sludge collection seat 5 and the two side walls of the sedimentation tank body 1 form a sludge collection area 19. The sludge collection seat 5 is trapezoidal, allowing wastewater on its upper surface to flow quickly to the sludge collection area 19 during rinsing. A scraper 9 and a brush 10 are installed at the upper end of the sludge collection seat 5. The lower surface of the brush 10 is machined with bristles 16. A rectangular cylinder 15 is connected to the upper ends of the scraper 9 and the brush 10. The movement of the rectangular cylinder 15 moves the scraper 9 and the brush 10. The upper end of the sedimentation tank 1 is equipped with a transmission mechanism 8 that drives two rectangular cylinders 15. The transmission mechanism 8 drives the rectangular cylinders 15 to move. The inner wall of the sedimentation tank 1 is connected to a sludge cleaning rod 12 located on one side of the sludge collection seat 5. The sludge cleaning rod 12 is slightly higher than the scraper 9. When the scraper 9 moves to one side of the sludge collection seat 5, the scraper 9 moves upward and scrapes off the sludge stuck to the side wall of the scraper 9 through the sludge cleaning rod 12, effectively preventing the sludge from sticking to the side wall of the scraper 9 (because it is cleaned regularly, the height of the sludge settling at the upper end of the sludge collection seat 5 is lower than the highest position of the scraper 9, and when scraping sludge, the sludge accumulated on one side of the scraper 9 will not be higher than the scraper 9). The bottom center of the sedimentation tank 1 is connected to a base 2. The side of the sedimentation tank 1 is connected to a drain pipe with a valve. The bottom of the sedimentation tank 1 is connected to a pair of sludge discharge pipes 18 located below the two sludge collection areas 19. Both sludge discharge pipes 18 are connected to an external sludge pump.

[0047] The rectangular cylinder 15 is equipped with an interlaced transmission mechanism 6 that controls the relative sliding of the scraper 9 and brush 10, working together to scrape and brush the sludge. The bottom ends of both the scraper 9 and brush 10 are trapezoidal openings, matching the upper end of the sludge collection seat 5. A second touch switch is located on the lower surface of the rectangular cylinder 15, directly above the scraper 9. During scraping, the scraper 9 contacts the upper surface of the sludge collection seat 5; after scraping, the brush 10 contacts the upper end of the sludge collection seat 5, working together to wash the upper surface of the sludge collection seat 5, making the sedimentation tank cleaner. A water control component 4 is installed on the upper inner wall of the sedimentation tank 1, located directly above the sludge collection seat 5. The water control component 4 includes a water storage cylinder 41 and a piston 42 slidably disposed inside the water storage cylinder 41. One end of the water storage cylinder 41 is connected to a suction pipe 11, which is connected to an external water tank. The bottom end of the water control component 4 is equipped with a spray washing mechanism 7, and the outside of the water control component 4 is provided with a transmission component 20 for controlling the inflow and outflow of water inside the water control component 4. The transmission component 20 is driven by a transmission mechanism 8.

[0048] Specifically, the spraying mechanism 7 includes a water outlet pipe 71 installed at the bottom of the water storage tank 41. The lower surface of the water outlet pipe 71 is connected to several nozzles 72. The end of the water outlet pipe 71 near the water suction pipe 11 is connected to the water storage tank 41 through a connecting pipe 73. A first one-way valve is provided on the connecting pipe 73. When the piston 42 moves toward the water suction pipe 11, the water inside the water storage tank 41 enters the water outlet pipe 71 through the connecting pipe 73 and is then sprayed out through the nozzles 72. A second one-way valve is provided on the water suction pipe 11. When the piston 42 moves away from the water suction pipe 11, the water suction pipe 11 will draw water from the external water pool into the water storage tank 41. When the piston 42 moves toward the water suction pipe 11, the water in the water storage tank 41 will not be discharged through the water suction pipe 11. The transmission mechanism 8 includes a pair of lead screws 82 rotatably connected to the inner wall of the sedimentation tank 1. The side walls of the two lead screws 82 are fitted with sleeve blocks 81. The inner wall of the sedimentation tank 1 is fixedly connected to a protective cover 3 covering the outside of the lead screws 82. The two sleeve blocks 81 are slidably connected to the two protective covers 3 respectively. The two lead screws 82 are driven by a pulley assembly 17. One of the lead screws 82 is driven by a servo motor (servo motor is existing technology and is not shown in the figure).

[0049] Furthermore, the transmission assembly 20 includes a magnetic ring 201 slidably sleeved on the outer wall of the water storage cylinder 41. One end of the piston 42 is fixedly connected to a magnet block that attracts the magnetic ring 201. When the magnetic ring 201 moves, it will drive the piston 42 to move synchronously. Both ends of the magnetic ring 201 are fixedly connected to connecting rods 202. The two connecting rods 202 are respectively fixedly connected to the two sleeve blocks 81. The connecting rods 202 are driven to move through the transmission mechanism 8. The movement of the connecting rods 202 causes the magnetic ring 201 to slide on the outer wall of the water storage cylinder 41, and finally drives the piston 42 to slide inside the water storage cylinder 41.

[0050] The magnetic ring 201 is inverted U-shaped, allowing it to slide outside the water storage tank 41, avoiding the spraying mechanism 7. Each of the connecting rods 202 has a contact rod 14 fixedly connected to both sides. The inner walls of both sides of the sedimentation tank 1 are equipped with a first touch switch 13 located at the same horizontal line as the two contact rods 14. The servo motor, sludge pump, and hydraulic cylinder 604 are controlled by the contact rods 14 contacting the first touch switch 13.

[0051] The interleaved transmission mechanism 6 includes a first rack 601 and a second rack 602 that slide through the lower surface of the rectangular tube 15. The bottom ends of the first rack 601 and the second rack 602 are fixedly connected to the scraper 9 and the brush plate 10, respectively. The first rack 601 and the second rack 602 are driven by a transmission member 605. The transmission member 605 includes a rotating shaft 6051 that is rotatably connected to the inner wall of the rectangular tube 15. The side wall of the rotating shaft 6051 is fixedly sleeved with a gear 6052 that meshes with the first rack 601 and the second rack 602. A transmission block 603 is fixedly connected to the side of the first rack 601. A hydraulic cylinder 604 for controlling the lifting and lowering of the transmission block 603 is installed on the inner wall of the top of the rectangular cylinder 15. When the telescopic end of the hydraulic cylinder 604 retracts, the first rack 601 is driven to move upward through the transmission block 603, and finally the scraper 9 is driven to move upward. When the first rack 601 moves upward, it is driven to move downward through the meshing of the gear 6052 with the second rack 602, and finally the brush 10 is driven to move downward, thereby realizing the adjustment of the position of the scraper 9 and the brush 10.

[0052] Furthermore, the system also includes a controller. Both first touch switches 13 are electrically connected to the controller, which is electrically connected to the sludge pump, hydraulic cylinder 604, and servo motor. When one of the contact rods 14 contacts the first touch switch 13 above the sludge cleaning rod 12, the first touch switch 13 sends an electrical signal to the controller. The controller then starts the sludge pump and hydraulic cylinder 604 (the telescopic end of hydraulic cylinder 604 extends), and controls the servo motor to pause operation. Notably, the retraction of the telescopic end of hydraulic cylinder 604 causes the first rack 601 and scraper 9 to move upwards. When scraper 9 contacts the second touch switch at the bottom of rectangular cylinder 15, the second touch switch sends a signal to the controller, controlling the servo motor to resume operation. When the other contact rod 14 contacts the other first touch switch 13, the other first touch switch 13 sends an electrical signal to the controller, controlling the sludge pump and servo motor to stop operation, and the telescopic end of hydraulic cylinder 604 to retract.

[0053] The working principle of this embodiment is as follows: After the water in the sedimentation tank 1 has settled, the valve on the drain pipe is opened to drain the upper layer of clear water. After draining, the valve is closed, and the servo motor is started to drive one of the lead screws 82 to rotate. Through the pulley assembly 17, the other lead screw 82 is driven to rotate (the pulley assembly includes pulleys sleeved on one end of the two lead screws 82, and the two pulleys are driven by a belt). The rotation of the two lead screws 82 drives the two sleeve blocks 81 to move to one side, thereby driving the scraper 9 to move to one side through the two rectangular cylinders 15. In the initial state, the scraper 9 contacts the upper end of the sludge collection seat 5, thereby moving the sludge collection seat 5. The sludge settled at the top hangs down and is pushed to the sludge collection area 19 on one side. When the corresponding contact rod 14 contacts the first contact switch 13, the first contact switch 13 controls the servo motor to stop working and starts the sludge pump to remove the sludge in the sludge collection area 19. At the same time, the hydraulic cylinder 604 is started, and at this time the cleaning rod 12 contacts the upper side of the scraper 9. The telescopic end of the hydraulic cylinder 604 retracts, driving the transmission block 603 to move upward. The upward movement of the transmission block 603 drives the scraper 9 to move upward. Under the meshing of the gear 6052, the second rack 602 moves downward, thereby driving the brush plate 10 to move downward and allowing the bristles 16 to concentrate with the sludge. When the upper end of the seat 5 contacts the scraper 9, the cleaning rod 12 will scrape off the sludge on the side of the scraper 9 as the scraper 9 moves upward (a second touch switch is provided on the lower surface of the rectangular cylinder 15, located directly above the scraper 9). When the scraper 9 moves upward and contacts the second touch switch, the controller starts the servo motor, which drives the two lead screws 82 to continue rotating, causing the two sleeve blocks 81 to move back, and finally driving the brush plate 10 to move back. It is worth noting that when the scraper 9 scrapes sludge to one side, the piston 42 is driven to move to one side synchronously through the transmission assembly 20, filling the water storage tank 41 with water. When the brush plate 10 moves back, the piston 42 is driven to move to one side synchronously through the transmission assembly 20. The moving component 20 drives the piston 42 to move back, thereby squeezing the water in the water storage tank 41 into the water outlet pipe 71, and finally spraying it downward through multiple nozzles 72. With the cooperation of the brush plate 10, the sludge collection seat 5 is washed, making the settled sludge cleaner. When another contact rod 14 contacts the corresponding first contact switch 13 (the scraper 9 and brush plate 10 move to the inner edge of the sedimentation tank 1, and the sludge in the two sludge collection areas 19 is pumped out), the controller controls the servo motor to turn off, the sludge pump to turn off, the hydraulic cylinder 604 moves upward, making the brush plate 10 move upward and the scraper 9 move downward, which is convenient for the next sludge cleaning.
