Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to an integrated wastewater enhanced pretreatment device. Background Technology

[0002] Integrated wastewater pretreatment equipment is a comprehensive facility specifically designed for the pretreatment stage of wastewater treatment. This equipment integrates multiple pretreatment steps of wastewater into one device to achieve continuous, automated, and efficient treatment.

[0003] Currently, common integrated equipment mainly includes an equalization tank, a sedimentation tank, a flocculation tank, and a disinfection tank arranged in sequence. During operation, wastewater first enters the equalization tank, where a screen is installed between the equalization tank and the buffer tank. Large particles such as garbage in the wastewater are then filtered by the screen and flow into the buffer tank. Suspended solids in the wastewater then settle in the sedimentation tank. Afterward, the wastewater undergoes further flocculation treatment in the flocculation tank, and finally, it is discharged after disinfection.

[0004] However, as working hours increase, a lot of sediment will inevitably accumulate at the bottom of the equalization tank, requiring frequent shutdowns for cleaning, which can easily reduce the wastewater treatment speed. Summary of the Invention

[0005] To improve the speed of wastewater treatment, this application provides an integrated wastewater enhanced pretreatment device.

[0006] This application provides an integrated wastewater enhanced pretreatment equipment, which adopts the following technical solution: An integrated wastewater enhanced pretreatment equipment includes a main body, wherein the main body has a wastewater tank, a sedimentation tank, a flocculation tank and a disinfection tank connected in sequence. The equipment body is provided with an inlet pipe that connects to the sewage tank and an outlet pipe that connects to the disinfection tank. A collection box is installed on the outer wall of the equipment body, and the collection box is located on the side of the sewage tank away from the sedimentation tank. A guide block is disposed on the device body. The guide block is located in the sedimentation tank and close to the collection box. The guide block is inclined and has a guide surface that connects the bottom of the sedimentation tank and the opening of the collection box. The equipment body is provided with a mounting frame located above the sewage tank. The mounting frame is provided with a mounting base. The bottom of the mounting base is provided with multiple telescopic columns. The mounting frame is provided with a drive assembly that drives the mounting base to slide back and forth between the sedimentation tank and the collection box. A pusher plate slides up and down on the telescopic column. The outer wall of the pusher plate is slidably connected to the wall of the sewage tank. The pusher plate has multiple filter holes. The mounting base is provided with an elastic driving component that drives the pusher plate to abut against the bottom of the sewage tank; When the pusher plate approaches the collection box, the pusher plate slides on the guide surface, and at this time the pusher plate slides upward on the telescopic column; A locking component is provided on the mounting base, and when the pusher plate moves close to the collection box, the locking component locks the pusher plate; An unlocking component is provided on the mounting bracket. When the pusher plate moves to the side of the sewage tank away from the collection box, the unlocking component unlocks the pusher plate.

[0007] By adopting the above technical solution, the inlet pipe introduces sewage into the sewage tank, the sedimentation tank is used for preliminary removal of suspended solids, the flocculation tank adds flocculants to promote the sedimentation of impurities, and the final disinfection tank performs sterilization and disinfection. The collection box and guide block effectively collect and discharge sediment, reducing the accumulation of sediment and large pieces of material in the sewage tank. The combination of the mounting frame, mounting base, telescopic column, and pusher plate, driven by the drive component, realizes the reciprocating motion of the pusher plate in the sewage tank, effectively pushing sediment and large pieces of material towards the collection box. The whole process is simple; the pusher plate can push sediment and large pieces of material towards the collection box without interrupting sewage treatment for cleaning, greatly improving the sewage treatment speed.

[0008] Optionally, the locking assembly includes a locking pin and a locking spring; The mounting base is provided with a mounting block at the bottom, the locking post is slidably connected to the mounting block, the side wall of the pusher plate is provided with a locking groove for the locking post to be inserted, and the locking post is provided with a downward-facing locking surface for the pusher plate to slide. The locking spring is mounted on the mounting block. When the locking pin is aligned with the locking groove, the locking spring pushes the locking pin into the locking groove.

[0009] By adopting the above technical solution, the locking component, through the cooperation of the locking post and the locking spring, realizes the automatic locking of the pusher plate when it approaches the collection box, reducing the possibility of pushing sediment and large pieces of material away from the collection box when the pusher plate moves away from the collection box.

[0010] Optionally, the unlocking component includes an unlocking post and an unlocking block; The unlocking block is disposed on the outer peripheral side wall of the locking post, the mounting block has a sliding hole for sliding connection of the unlocking block, and the unlocking block has an unlocking surface inclined towards the push plate; The unlocking post is disposed on the mounting bracket; When the pusher plate approaches the side wall of the sewage tank away from the collection box, the unlocking post slides through the sliding hole. At this time, the unlocking post slides on the unlocking surface, pushing the locking post away from the locking groove.

[0011] By adopting the above technical solution, the unlocking component, through the cooperation of the unlocking column and the unlocking block, realizes the automatic unlocking of the pusher plate when it is far away from the collection box, so that the pusher plate can smoothly return to the sewage tank for the next scraping operation.

[0012] Optionally, the end of the unlocking post is provided with an arc-shaped structure.

[0013] By adopting the above technical solution, the arc-shaped structure design at the end of the unlocking column reduces the friction between the unlocking column and the unlocking block, thereby improving the smoothness and efficiency of unlocking.

[0014] Optionally, the drive assembly includes a drive motor and a reciprocating lead screw, the reciprocating lead screw being rotatably connected to the mounting bracket, and the mounting seat being threadedly connected to the reciprocating lead screw; The drive motor is mounted on the mounting bracket, and the output shaft of the drive motor is coaxially arranged and connected to the reciprocating lead screw.

[0015] By adopting the above technical solution, the drive assembly realizes the reciprocating motion of the mounting base and the push plate through the cooperation of the drive motor and the reciprocating screw.

[0016] Optionally, the pusher plate includes a plate body and a connecting ball; The plate is provided with a plurality of rotating holes at even intervals, and the connecting ball is rotatably accommodated in the rotating hole. The outer wall of the connecting ball is slidably connected to the wall of the rotating hole. A connecting shaft is provided on the top outer wall of the connecting ball, the connecting shaft is rotatably connected to the plate, and the water filter hole is opened in the connecting ball; The plate is equipped with a control component, which controls the connecting ball to rotate until the holes on both sides of the filter hole correspond one-to-one with the holes on both sides of the rotating hole and are connected. When the pusher plate moves downward to abut the bottom wall of the wastewater tank, the control component controls the connecting ball to rotate so that the two openings of the filter hole are reversed.

[0017] By adopting the above technical solution, the pusher plate, through the cooperation of the plate body, connecting ball and control components, realizes the rotation and adjustment of the orifices on both sides of the filter hole.

[0018] Optionally, the control assembly includes a control gear, a control rack, a control worm gear, a control worm, a control belt, and a control shaft; The control shaft is rotatably connected to the plate body and parallel to the connecting shaft; the control belt is sleeved on the connecting shaft and the control shaft. The control worm gear is disposed on the outer periphery of the control shaft and rotates within the plate body; the control worm is rotatably connected within the plate body; and the control worm meshes with the control worm gear. The control rack is disposed on the side wall of the sewage tank, and the plate has a control groove for the control rack to slide up and down. The control gear is disposed on the outer periphery of the control worm, and the control gear protrudes into the control groove; When the pusher plate moves downwards towards the bottom wall of the sewage tank, the control rack slides in the control groove, at which time the control rack meshes with the control gear.

[0019] By adopting the above technical solution, when the pusher plate moves downwards towards the bottom wall of the sewage tank, the control rack slides within the control groove and meshes with the control gear, thereby driving the control worm gear and control worm to rotate. The rotation of the control worm, in turn, drives the connecting shaft to rotate via the control belt, thus realizing the rotation of the connecting ball. This design is not only simple in structure and easy to operate, but also enables precise control of the connecting ball.

[0020] Optionally, the telescopic column includes an inner column and an outer column. The outer column is fixedly installed inside the pusher plate, and the inner column is installed at the bottom of the mounting base. The inner column slides up and down on the outer column.

[0021] By adopting the above technical solution, the telescopic column adopts a combination design of inner column and outer column. The outer column is fixedly set in the pusher plate, and the inner column is set at the bottom of the mounting base and slides up and down in the outer column, so that the pusher plate can slide up and down as needed.

[0022] Optionally, the elastic driving component is a driving spring, which is sleeved on the outer periphery of the telescopic column, with one end of the driving spring abutting against the mounting base and the other end abutting against the outer column.

[0023] By adopting the above technical solution, when the pusher plate scrapes away sediment, the drive spring provides elastic support, allowing the pusher plate to fit tightly against the bottom wall of the sewage tank, thus improving the scraping effect. At the same time, the elasticity of the drive spring also buffers the impact force on the pusher plate during movement, reducing the possibility of equipment damage.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. The collection box and guide block effectively collect and discharge sediment, reducing the accumulation of sediment and large materials in the sewage tank, eliminating the need to stop sewage treatment for cleaning, and greatly improving the sewage treatment speed. 2. When the pusher plate scrapes away sediment, the drive spring provides elastic support, allowing the pusher plate to fit tightly against the bottom wall of the wastewater tank, improving the scraping effect. At the same time, the elasticity of the drive spring also buffers the impact force on the pusher plate during movement, reducing the possibility of equipment damage. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0028] This application discloses an integrated wastewater enhanced pretreatment device.

[0029] See Figure 1 and Figure 2 The integrated equipment includes a main body 1, which has a sewage tank 11, a sedimentation tank 12, a flocculation tank 13, and a disinfection tank 14 arranged in sequence. Multiple water supply pipes are fixedly connected to the main body 1, and these pipes sequentially connect to the sewage tank 11, sedimentation tank 12, flocculation tank 13, and disinfection tank 14. A fence 19 is fixedly connected to the main body 1, located inside the sewage tank 11, and covering the openings of the water supply pipes.

[0030] The equipment body 1 is fixedly connected to an inlet pipe 15, which connects to a sewage tank 11, allowing the sewage to be treated to be introduced into the sewage tank 11. The equipment body 1 is also fixedly connected to a drain pipe 16, which connects to a disinfection tank 14, used to discharge disinfected sewage. During sewage treatment, the sewage first flows into the sewage tank 11, where a screen 19 filters out large particles. The sewage then flows through a water pipe into a sedimentation tank 12 for sedimentation. After sedimentation, the sewage flows into a flocculation tank 13, where flocculants are added to flocculate and precipitate particles and other impurities. Finally, the sewage enters the disinfection tank, is disinfected, and then discharged through the drain pipe 16. The specific sedimentation, flocculation, and disinfection processes described in this application are prior art and will not be elaborated upon here.

[0031] The integrated device also includes a collection box 17, which is detachably fixed to the outer wall of the device body 1. The collection box 17 has a collection trough 171, and the opening of the collection trough 171 is on the same plane as the opening of the sewage tank 11. The collection box 17 is located on the side of the sewage tank 11 away from the sedimentation tank 12. During use, the collection box 17 stores large impurities collected in the sewage tank 11.

[0032] The main body of the equipment 1 is fixedly connected to a mounting frame 3, which is located directly above the sewage tank 11. The mounting frame 3 is provided with a mounting base 4 and a drive assembly 6. The drive assembly 6 drives the mounting base 4 to slide back and forth between the sedimentation tank 12 and the collection box 17.

[0033] The drive assembly 6 includes a drive motor 61 and a reciprocating screw 62. The reciprocating screw 62 is rotatably connected to the mounting bracket 3, and the mounting seat 4 is threadedly connected to the reciprocating screw 62. When the reciprocating screw 62 rotates, it drives the mounting seat 4 to reciprocate between the collection box 17 and the sedimentation tank 12. The drive motor 61 is fixedly connected to the mounting bracket 3, and the output shaft of the drive motor 61 is coaxially arranged and fixedly connected to the reciprocating screw 62. When the drive motor 61 starts, it drives the reciprocating screw 62 to rotate. When the mounting seat 4 moves to the vicinity of the collection box 17 and the sedimentation tank 12, the drive motor 61 pauses briefly and then restarts to continue driving the reciprocating screw 62 to rotate. In this application, the output power of the drive motor 61 is low, and when the drive motor 61 starts, it drives the reciprocating screw 62 to rotate at a low speed.

[0034] A telescopic column 42 is fixedly connected to the bottom of the mounting base 4. Multiple telescopic columns 42 are evenly spaced, and the line connecting the telescopic columns 42 is perpendicular to the line connecting the collection box 17 and the sedimentation tank 12. Each telescopic column 42 includes an inner column 421 and an outer column 422. The inner column 421 is fixedly connected to the bottom of the mounting base 4, and the outer column 422 slides vertically around the outer periphery of the inner column 421. A limiting block is fixedly connected to the outer wall of the inner column 421, and the outer column 422 has a limiting groove extending vertically. The limiting block slides vertically into the limiting groove, preventing the outer column 422 from detaching from the inner column 421.

[0035] The integrated device also includes a pusher plate 7, which is slidably connected within the wastewater tank 11, with its outer wall slidably connected to the tank wall of the wastewater tank 11. An outer column 422 is fixedly embedded within the pusher plate 7, allowing the pusher plate 7 to slide up and down relative to the inner column 421. The pusher plate 7 has multiple filter holes 73 spaced evenly apart.

[0036] See Figure 2 and Figure 3 The mounting base 4 is equipped with an elastic drive component to drive the pusher plate 7 downward until its bottom abuts against the bottom wall of the sewage tank 11. The elastic drive component is a drive spring 18, which is sleeved on the outer periphery of the telescopic column 42. The top of the drive spring 18 abuts against the top of the mounting base 4, and the bottom of the drive spring 18 abuts against the top of the outer column 422. When the drive spring 18 is released elastically, it drives the pusher plate 7 downward. When the mounting base 4 moves from the position of the sewage tank 11 near the side wall of the sedimentation tank 12 towards the collection box 17, the pusher plate 7 pushes the sediment deposited at the bottom of the sewage tank 11 and large pieces of material floating in the sewage toward the collection box 17. At this time, the sewage is filtered by the filter holes 73, so that the sediment and large pieces of material can move away from the screen 19. On the one hand, this reduces the rate at which the sewage is transferred to the sedimentation tank 12 due to the screen 19 being blocked, and on the other hand, it reduces the amount of impurities in the sedimentation tank 12, thus reducing the working pressure of the sedimentation tank 12.

[0037] See Figure 1 and Figure 2The integrated device also includes a guide block 2, which is fixedly connected to the device body 1. The guide block 2 is located inside the sedimentation tank 12 and close to the collection box 17. The guide block 2 has an inclined guide surface 21, which connects to the bottom wall of the sedimentation tank 12 and the opening of the collection box 17. When the pusher plate 7 pushes the sediment and large pieces of material close to the collection box 17, the pusher plate 7 pushes the sediment and large pieces of material to slide on the guide surface 21, so that the sediment and large pieces of material can be transferred to the collection box 17. When the pusher plate 7 slides on the guide surface 21, the guide block 2 pushes the pusher plate 7 to slide upward. At this time, the outer column 422 slides on the inner column 421, and the drive spring 18 enters the compression state, keeping the bottom of the pusher plate 7 in contact with the guide surface 21. Until the pusher plate 7 moves to the space between the opening of the sewage tank 11 and the opening of the collection tank 171, the drive motor 61 stops, which facilitates the sediment and large pieces of material to enter the collection box 17.

[0038] See Figure 3 and Figure 4 The integrated device also includes a locking component 8, which is located on the mounting base 4. When the pusher plate 7 moves to the slot of the collection groove 171 near the collection box 17, the locking component 8 locks the pusher plate 7.

[0039] The locking assembly 8 includes a locking post 81 and a locking spring 82. A mounting block 41 is fixedly connected to the bottom of the mounting base 4, and the mounting block 41 faces one vertical sidewall of the pusher plate 7. A receiving groove is formed on the side of the mounting block 41 facing the pusher plate 7, extending away from the pusher plate 7. The locking post 81 is a long, rectangular column structure and is slidably connected within the receiving groove. A locking groove 711 is formed on the vertical sidewall of the pusher plate 7 facing the mounting block 41, corresponding to the locking post 81. The locking spring 82 is installed within the receiving groove, with one end abutting against the end of the locking post 81 and the other end abutting against the groove wall away from the groove opening. A locking surface 811 is inclined on the side of the locking post 81 away from the locking spring 82, with the locking surface 811 facing downwards. As the pusher plate 7 moves upward and approaches the mounting base 4, it slides on the locking surface 811, pushing the locking pin 81 into the receiving groove. When the locking groove 711 and the locking pin 81 are aligned, the locking spring 82 is released elastically, pushing the locking pin 81 into the locking groove 711, so that the pusher plate 7 enters the fixed state.

[0040] See Figure 5 and Figure 6The integrated device also includes an unlocking component 9, which is mounted on the mounting frame 3. When the pusher plate 7 moves to the side of the sewage tank 11 away from the collection box 17, the unlocking component 9 unlocks the pusher plate 7. The unlocking component 9 includes an unlocking column 91 and an unlocking block 92. The unlocking block 92 is fixedly connected to the outer peripheral side wall of the locking column 81. The mounting block 41 has a sliding hole 411, and the unlocking block 92 is slidably connected in the sliding hole 411. The unlocking block 92 has an unlocking surface 921 at an angle, facing the pusher plate 7.

[0041] The unlocking post 91 is fixedly connected to the mounting bracket 3, and the end of the unlocking post 91 near the mounting block 41 has an arc-shaped structure. When the locking post 81 is inserted into the locking post 81, the unlocking post 91 is aligned with the unlocking surface 921. When the pusher plate 7 approaches the side wall of the sewage tank 11 away from the collection box 17, the unlocking post 91 slides through the sliding hole 411. At this time, the unlocking post 91 slides on the unlocking surface 921, pushing the locking post 81 out of the locking groove 711. Then the drive motor 61 pauses briefly, and at the same time the drive spring 18 (the drive spring 18 is in...) Figure 3 The winning bidder releases its elasticity, pushing the pusher plate 7 downwards until it abuts against the bottom wall of the sewage tank 11, and then drives the motor 61 (the drive motor 61 is in...). Figure 2 (If the bid is successful) Continue to start, causing the pusher plate 7 to move towards the collection box 17, and once again push the sediment and large pieces of material in the sewage tank 11 towards the collection box 17.

[0042] See Figure 5 and Figure 7 During the process of the pusher plate 7 pushing sediment and large materials into the collection box 17 through the guide surface 21, the sediment and large materials are prone to block the filter holes 73 near the collection box 17 under pressure. This reduces the number of filter holes 73 that can be used for sewage to pass through when the pusher plate 7 pushes sediment and large materials into the collection box 17 next time. At this time, some sewage is easily pushed into the collection box 17 by the pusher plate 7, which affects the sewage treatment effect.

[0043] See Figure 7 To reduce the possibility of clogging of the filter holes 73, the pusher plate 7 includes a plate body 71 and a connecting ball 72, and an outer column 422 (the outer column 422 is in Figure 3 The connecting ball 72 (as indicated by the bid) is embedded and fixed inside the plate 71. Multiple rotating holes 712 are evenly spaced on the plate 71. The connecting ball 72 is rotatably accommodated within each rotating hole 712, and a filter hole 73 is formed on the connecting ball 72. The rotating holes 712 form openings on opposite sides of the plate 71, and the outer wall of the connecting ball 72 is slidably connected to the wall of the rotating hole 712.

[0044] See Figure 7 and Figure 8A connecting shaft 721 is fixedly connected to the top outer wall of the connecting ball 72. The connecting shaft 721 is rotatably connected to the plate 71, so that the connecting ball 72 can make circular motion on the horizontal plane within the rotating hole 712.

[0045] See Figure 5 and Figure 7 The plate 71 is equipped with a control component, which controls the connecting ball 72 to rotate until the holes on both sides of the filter hole 73 correspond one-to-one with the holes on both sides of the rotating hole 712 and are connected; when the pusher plate 7 moves downward to abut the bottom wall of the sewage tank 11, the control component controls the connecting ball 72 to rotate until the holes on both sides of the filter hole 73 are reversed.

[0046] See Figure 7 and Figure 8 The control components include a control gear 51 and a control rack 52 (the control rack 52 is in...). Figure 4 The control assembly includes a control worm gear 53, a control worm 54, a control belt 55, and a control shaft 5. The control shaft 5 is rotatably connected within the plate 71 and parallel to the connecting shaft 721. The diameters of the control shaft 5 and the connecting shaft 721 are equal and they are on the same plane. The control belts 55 are connected end-to-end and slide through the plate 71. There are multiple control belts 55, each fitted into a connecting hole on the same horizontal line, and a control sleeve is fitted onto the outer circumference of the control shaft 5. When the control shaft 5 rotates, the control belts 55 drive the connecting shaft 721 to rotate, causing the connecting ball 72 to enter a rotating state.

[0047] The control worm gear 53 is fixedly connected to the outer periphery of the control shaft 5 and rotates within the plate 71. The control worm 54 is rotatably connected within the plate 71, meshes with the control worm gear 53, and the control worm 54 and the control worm gear 53 satisfy the self-locking parameters.

[0048] See Figure 5 and Figure 7 The control rack 52 is fixedly connected to the mounting bracket 3, and the control rack 52 (the control rack 52 in) Figure 4 (The marked area) is located at the sedimentation tank 12. The plate 71 has a control groove 713 (the control groove 713 is located in...) Figure 1 (As indicated by the mark), the control groove 713 extends vertically. When the pusher plate 7 moves close to the sedimentation tank 12 and the drive motor 61 enters a paused state, the control groove 713 aligns with the control rack 52. Then, when the pusher plate 7 moves downward, the control rack 52 slides through the control groove 713. The control gear 51 is fixedly connected to the outer periphery of the control worm gear 54, and the control gear 51 is rotatably connected to the plate body 71, with a portion of the control gear 51 protruding into the control groove 713.

[0049] As the pusher plate 7 moves downwards towards the bottom wall of the wastewater tank 11, the control rack 52 slides through the control groove 713. At this time, the control rack 52 meshes with the control gear 51, driving the control worm 54 to rotate. Then, the control worm wheel 53 drives the control belt 55 through the control shaft 5, causing the connecting ball 72 to rotate, thus achieving the rotation of the openings on both sides of the filter hole 73. When the pusher plate 7 moves towards the collection box 17 again, wastewater is flushed into the filter hole 73, which can unclog the filter hole 73 and reduce the possibility of blockage.

[0050] The implementation principle of the integrated wastewater enhanced pretreatment equipment in this application embodiment is as follows: As wastewater is continuously fed into the wastewater tank 11, sediment will accumulate at the bottom of the tank, and large pieces of material will be present in the wastewater. At this time, the drive motor 61 is activated, causing the mounting base 4 to reciprocate between the sedimentation tank 12 and the collection box 17. When the mounting base 4 approaches the collection box 17, the pusher plate 7 pushes the sediment and large pieces of material towards the collection box 17. After passing through the guide surface 21, the sediment and large pieces of material are pushed into the collection box 17, which helps to reduce the amount of sediment and large pieces of material in the wastewater tank 11 and increases the rate at which wastewater is transported to the sedimentation tank 12.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
