Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for municipal engineering. Background Technology

[0002] Traditional treatment processes often employ a combination of units such as screens, sedimentation tanks, and biological reactors, relying on physical sedimentation and biodegradation. However, their effectiveness in removing recalcitrant organic matter, trace pollutants, color, and odor is limited. With increasingly stringent environmental standards, single processes are insufficient to meet effluent requirements. Therefore, advanced treatment technologies such as activated carbon adsorption and chemical dosing are increasingly being integrated. Meanwhile, early equipment suffered from low adsorption efficiency and rapid local saturation due to fixed activated carbon plates, as well as high costs and secondary pollution caused by uneven chemical dosing. This has driven the development of optimized designs such as dynamic contact and precise dosing to improve treatment efficiency and stability.

[0003] Patent CN218988948U discloses a wastewater treatment device, including a pump, a chemical tank unit, a PLC controller, and a sedimentation-reaction unit. The wastewater treatment device also includes a multi-channel directional valve and a storage ring. The multi-channel directional valve has a dosing channel, a dispensing channel, a cleaning channel, and a common channel connected to the storage ring. The sedimentation-reaction unit includes a flocculation sedimentation tank and an intermediate reaction tank, which are electrically connected in parallel to the PLC controller. The other end of the flocculation sedimentation tank is connected to the dispensing channel. During chemical dosing, the multi-channel directional valve selects the corresponding channel of each chemical tank, draws the corresponding volume of chemical agent into the storage unit, and then pushes it to the sedimentation-reaction unit by the pump.

[0004] However, when the above-mentioned device is in use, it is difficult to achieve full mixing of the wastewater treatment agent and the wastewater during the agent dosing process, resulting in low wastewater treatment efficiency after agent dosing. Therefore, a wastewater treatment device for the field of municipal engineering is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sewage treatment device in the field of municipal engineering, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a sewage treatment device in the field of municipal engineering, including a treatment tank, a top box provided on the treatment tank, a reciprocating screw rotatably connected to the inner wall of the treatment tank, a treatment agent box installed in the treatment tank, a rotating column rotatably connected to the inner wall of the treatment tank, a movable block movably connected to the circumferential surface of the reciprocating screw, a protruding plate fixedly connected to the top of the movable block, an elastic telescopic rod fixedly connected to the inner wall of the treatment agent box, a sealing plate fixedly connected to the telescopic end of the elastic telescopic rod, a protrusion provided at the bottom of the sealing plate, a pulley 1 provided on the reciprocating screw, a pulley 2 provided on the rotating column 1, a rotating rod fixedly connected to the circumferential surface of the rotating column 1, a rotating block rotatably connected to the inner wall of the rotating rod, a gear ring fixedly connected to the circumferential surface of the rotating block, a gear fixedly connected to the inner wall of the treatment tank, a spiral blade fixedly connected to the circumferential surface of the rotating block, and a motor provided in the treatment tank. The treatment tank is equipped with a limiting post, and the inner wall of the top box is equipped with a deodorizing mechanism for eliminating odors and a cleaning mechanism for removing debris. The moving block is slidably connected to the circumferential surface of the limiting post, and the reciprocating screw is fixedly connected to the output end of the motor. The first and second pulleys are connected to a belt drive, and the protrusion is located on the movement trajectory of the convex plate. The protrusion is used to drive the sealing plate to open the opening of the treatment agent box. The gear ring meshes with the gear, which can directly remove specific pollutants, reduce water quality indicators, improve the wastewater treatment quality of the device, improve the efficiency of the device in treating wastewater, accurately control the concentration of the agent, improve reaction efficiency, and improve the utilization efficiency of the device. The spiral blades can push the wastewater on both sides of the treatment tank through their spiral design, so that the wastewater on both sides of the treatment tank can move towards the center, which can accelerate the contact and fusion of wastewater treatment agents and wastewater, and improve the treatment efficiency of the device.

[0007] Preferably, the odor-eliminating mechanism includes a filter plate, a first fixing block, a pull rod, a vertical slider, a second elastic telescopic rod, and an activated carbon plate. The filter plate is fixedly connected to the inner wall of the top box. The first fixing block is fixedly connected to the top of the convex plate. The pull rod is rotatably connected to the circumferential surface of the first fixing block. The vertical slider is slidably connected to the inner wall of the top box. The second elastic telescopic rod is fixedly connected to the top of the vertical slider. The activated carbon plate is fixedly connected to the telescopic end of the second elastic telescopic rod. The odor-eliminating mechanism also includes a groove column, a hinge rod, a fixed column, and a trapping plate. The groove column is fixedly connected to the circumferential surface of the first rotating column. The hinge rod is rotatably connected to the circumferential surface of the groove column via a torsion spring. The fixed column is fixedly connected to the inner wall of the hinge rod. The trapping plate... The capture plate is fixedly connected to the circumferential surface of the fixed column. The activated carbon plate is in contact with the top box and is used to deodorize sewage generated by municipal engineering projects. The pull rod is rotatably connected to the circumferential surface of the vertical slider, allowing the activated carbon plate to move back and forth up and down. This improves the contact efficiency between the activated carbon plate and the sewage, increases the adsorption rate of the activated carbon plate on the sewage, adsorbs odors in the sewage, and improves the treatment quality of the sewage by the device. It also makes the rotation of the capture plate slower relative to the rotating column, which improves the pollutant capture efficiency of the capture plate and avoids a decrease in pollutant capture efficiency due to a large amount of pollutants captured on the surface of the capture plate while the rotation speed remains unchanged. This improves the overall quality of use of the device.

[0008] Preferably, the cleaning mechanism includes a third elastic telescopic rod, a buffer block, and a rotating plate. The third elastic telescopic rod is fixedly connected to the top of the convex plate, and the buffer block is fixedly connected to the telescopic end of the third elastic telescopic rod. The rotating plate is rotatably connected to the inner wall of the first fixed block. The cleaning mechanism also includes a second fixed block, a horizontal slider, a connecting rod, a second rotating column, a roller, and a scraper. The second fixed block is fixedly connected to the top of the activated carbon plate, the horizontal slider is slidably connected to the inner wall of the top box, the connecting rod is rotatably connected to the circumferential surface of the second fixed block, the second rotating column is rotatably connected to the inner wall of the horizontal slider, the roller is fixedly connected to the circumferential surface of the second rotating column, and the scraper is fixedly connected to the circumferential surface of the second rotating column. The buffer block and the rotating plate are connected to the inner wall of the first fixed block. The rotating plate contacts the wastewater and buffers the discharged wastewater. The connecting rod is rotatably connected to the circumferential surface of the horizontal slider. The roller contacts the filter plate, and the scraper contacts the filter plate. The scraper is used to move the debris remaining on the surface of the filter plate, so that the rotating plate can buffer and offset the impact force when the wastewater is discharged. This can prevent excessive impact force of the water flow when too much wastewater is discharged, which could damage the equipment parts inside the treatment tank and improve the service life of the device. The scraper can push the contaminants remaining on the surface of the filter plate, which can prevent the filter plate from clogging due to long-term use, ensure the efficiency of wastewater treatment, improve the self-cleaning ability of the device, and improve the wastewater treatment efficiency of the device.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This sewage treatment equipment in the field of municipal engineering, through the coordinated movement of the treatment tank, top box, reciprocating screw, treatment agent box, rotating column one, moving block, convex plate, elastic telescopic rod one, sealing plate, pulley one, belt, pulley two, rotating rod, gear ring, gear, rotating block, and spiral blades, can directly remove specific pollutants, reduce water quality indicators, improve the sewage treatment quality of the device, increase the efficiency of the device in sewage treatment, accurately control the concentration of the agent, improve reaction efficiency, and improve the utilization efficiency of the device. The spiral blades, through their spiral design, push the sewage on both sides of the treatment tank, enabling the sewage on both sides of the treatment tank to move towards the center, which can accelerate the contact and fusion of sewage treatment agents and sewage, and improve the treatment efficiency of the device.

[0011] 2. This sewage treatment equipment in the field of municipal engineering utilizes the coordinated movement of filter plates, fixed blocks, tie rods, vertical sliders, elastic telescopic rods, activated carbon plates, trough columns, hinged rods, fixed columns, and capture plates. This allows the activated carbon plates to move back and forth, enhancing the contact efficiency between the activated carbon plates and sewage, increasing the adsorption rate of the activated carbon plates on sewage, adsorbing odors in sewage, and improving the treatment quality of the sewage. Furthermore, the slower rotation of the capture plates relative to the rotating column improves the pollutant capture efficiency of the capture plates, preventing a decrease in pollutant collection efficiency due to excessive pollutants on the capture plate surface while the rotation speed remains constant, thus improving the overall performance of the equipment.

[0012] 3. This sewage treatment equipment in the field of municipal engineering utilizes the coordinated movement of three elastic telescopic rods, buffer blocks, rotating plates, two fixed blocks, horizontal sliders, connecting rods, two rotating columns, rollers, and scrapers. The rotating plates buffer and offset the impact force when sewage is discharged, preventing excessive impact from the water flow when too much sewage is discharged, which could damage internal equipment parts and extend the equipment's lifespan. The scrapers push away contaminants and debris on the filter plate surface, preventing clogging from prolonged use and ensuring efficient sewage treatment. This also enhances the device's self-cleaning ability and overall sewage treatment efficiency. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-9One embodiment of the present invention is as follows: a sewage treatment device in the field of municipal engineering, including a treatment tank 1, a top box 2 provided on the treatment tank 1, a reciprocating screw 3 rotatably connected to the inner wall of the treatment tank 1, a treatment agent box 4 installed in the treatment tank 1, a rotating column 5 rotatably connected to the inner wall of the treatment tank 1, a movable block 8 movably connected to the circumferential surface of the reciprocating screw 3, a protruding plate 9 fixedly connected to the top of the movable block 8, and an elastic telescopic rod 10 fixedly connected to the inner wall of the treatment agent box 4, the telescopic end of the elastic telescopic rod 10 being fixedly connected to... A sealing plate 11 is connected, and a protrusion is provided at the bottom of the sealing plate 11. A first pulley 12 is provided on the reciprocating screw 3, and a second pulley 14 is provided on the rotating column 5. A rotating rod 15 is fixedly connected to the circumferential surface of the rotating column 5. A rotating block 18 is rotatably connected to the inner wall of the rotating rod 15. A toothed ring 16 is fixedly connected to the circumferential surface of the rotating block 18. A gear 17 is fixedly connected to the inner wall of the processing tank 1. A spiral blade 19 is fixedly connected to the circumferential surface of the rotating block 18. A motor is provided in the processing tank 1, and a limit post is provided inside the processing tank 1.

[0025] When the device is in use, the process personnel first need to discharge the sewage generated by the municipal engineering project into the treatment tank 1 through the opening at the top of the top box 2. At this time, the motor will start synchronously, and the output end of the motor will drive the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 will drive the moving block 8 to rotate. However, at this time, the moving block 8 is limited by the limiting post. The limiting post will cause the moving block 8 to move laterally back and forth through the reciprocating groove on the surface of the reciprocating screw 3 during the rotation of the reciprocating screw 3. The movement of the moving block 8 will drive the convex plate 9 to move synchronously. After moving a certain distance, the convex plate 9 will make contact with the convex block at the bottom of the sealing plate 11. Upon contact, the convex plate 9 will squeeze and push the protrusion to rise. The rise of the protrusion will drive the sealing plate 11 to rise. During the rise, the sealing plate 11 will open the opening of the treatment agent box 4. At this time, the sewage treatment agent inside the treatment agent box 4 can flow into the interior of the top box 2 through the opening. The sewage treatment agent can come into contact with the sewage inside the top box 2. The movement of the sealing plate 11 can directly remove specific pollutants, reduce water quality indicators, improve the sewage treatment quality of the device, improve the efficiency of the device for sewage treatment, accurately control the concentration of the agent, improve the reaction efficiency, and improve the utilization efficiency of the device.

[0026] The inner wall of the top box 2 is provided with an odor-eliminating mechanism 6 for eliminating odors, and the inner wall of the top box 2 is provided with a cleaning mechanism 7 for cleaning debris. The moving block 8 is slidably connected to the circumferential surface of the limiting post. The reciprocating screw 3 is fixedly connected to the output end of the motor. The first pulley 12 is connected to the belt 13 for transmission, and the second pulley 14 is connected to the belt 13 for transmission. The protrusion is located on the movement trajectory of the protrusion plate 9, and the protrusion is used to drive the sealing plate 11 to open the opening of the treatment agent box 4. The toothed ring 16 meshes with the gear 17.

[0027] When the device is started, the rotation of the reciprocating screw 3 drives the pulley 12 to rotate. During the rotation of the pulley 12, the pulley 12 drives the pulley 14 to rotate via the belt 13. The rotation of the pulley 14 drives the rotating column 5 to rotate. The rotation of the rotating column 5 drives the rotating rod 15 to rotate. During the rotation of the rotating rod 15, the rotating rod 15 drives the rotating block 18 to rotate. The rotation of the rotating block 18 drives the spiral blade 19 to rotate around the rotating column 5. At the same time, during the rotation of the rotating block 18, the spiral blade 19 rotates... The rotation of the rotating block 18 will drive the gear ring 16 to rotate. During the rotation, the gear ring 16 will mesh with the gear 17, which will drive the rotating block 18 to rotate. The rotation of the rotating block 18 will drive the spiral blade 19 to continue to rotate. During the rotation, the spiral blade 19 can push the sewage on both sides of the treatment tank 1 through its spiral design, so that the sewage on both sides of the treatment tank 1 can move towards the center, which can accelerate the contact and fusion of sewage treatment agent and sewage, and improve the treatment efficiency of the device.

[0028] Overall working principle: The wastewater treatment agent inside the treatment agent box 4 can flow into the top box 2 through the opening. The wastewater treatment agent can come into contact with the wastewater inside the top box 2. The movement of the sealing plate 11 can directly remove specific pollutants, reduce water quality indicators, improve the wastewater treatment quality of the device, improve the efficiency of the device for wastewater treatment, accurately control the concentration of the agent, improve reaction efficiency, and improve the utilization efficiency of the device. The toothed ring 16 will drive the rotating block 18 to rotate, and the rotation of the rotating block 18 will drive the spiral blade 19 to continue to rotate. At this time, during the rotation of the spiral blade 19, the spiral blade 19 can push the wastewater on both sides of the treatment tank 1 through its own spiral design, so that the wastewater on both sides of the treatment tank 1 can move towards the center, which can accelerate the contact and fusion of wastewater treatment agent and wastewater, and improve the treatment efficiency of the device.

[0029] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the odor-eliminating mechanism 6 includes a filter plate 601, a fixing block 602, a pull rod 603, a vertical slider 604, an elastic telescopic rod 605, and an activated carbon plate 606. The filter plate 601 is fixedly connected to the inner wall of the top box 2, the fixing block 602 is fixedly connected to the top of the protruding plate 9, the pull rod 603 is rotatably connected to the circumferential surface of the fixing block 602, the vertical slider 604 is slidably connected to the inner wall of the top box 2, the elastic telescopic rod 605 is fixedly connected to the top of the vertical slider 604, and the activated carbon plate 606 is fixedly connected to the telescopic end of the elastic telescopic rod 605.

[0030] When the device is started, as workers discharge sewage from municipal engineering projects into the top box 2, the sewage comes into contact with the filter plate 601. The filter plate 601 traps large particles in the sewage. The sewage then passes through the filter plate 601 and comes into contact with the activated carbon plate 606. Simultaneously, the movement of the convex plate 9 moves the first fixed block 602, which in turn moves the pull rod 603. During this movement, the pull rod 603 changes its angle, which in turn raises the vertical slider 604. The rise of the vertical slider 604 raises the second elastic telescopic rod 605, which in turn raises the activated carbon plate 606. The activated carbon plate 606 can then move back and forth up and down, enhancing the contact efficiency between the activated carbon plate 606 and the sewage, increasing the adsorption rate of the activated carbon plate 606 on the sewage, adsorbing odors from the sewage, and improving the treatment quality of the sewage.

[0031] The deodorization mechanism 6 also includes a groove column 607, a hinge rod 608, a fixed column 609, and a capture plate 610. The groove column 607 is fixedly connected to the circumferential surface of the rotating column 5. The hinge rod 608 is rotatably connected to the circumferential surface of the groove column 607 through a torsion spring. The fixed column 609 is fixedly connected to the inner wall of the hinge rod 608. The capture plate 610 is fixedly connected to the circumferential surface of the fixed column 609. The activated carbon plate 606 is in contact with the top box 2 and is used to deodorize the sewage generated by municipal engineering. The pull rod 603 is rotatably connected to the circumferential surface of the vertical slider 604.

[0032] When the device is started, the rotation of the rotating column 5 drives the trough column 607 to rotate, which in turn drives the hinge rod 608 to rotate. The hinge rod 608 then drives the fixed column 609 to rotate, which in turn drives the capture plate 610 to rotate. During this rotation, the capture plate 610 captures fine pollutants in the wastewater. However, when the capture plate 610 captures a large amount of pollutants, the pores on its surface may become somewhat clogged, causing the capture plate 610 to rotate... During the process, the force-bearing area of ​​the water flow on the capture plate 610 increases. At this time, the capture plate 610 will drive the fixed column 609 to rotate. The rotation of the fixed column 609 will drive the hinge rod 608 to rotate on the inner wall of the groove column 607. At this time, the rotation of the capture plate 610 is slower than that of the rotating column 5, which can improve the pollutant capture efficiency of the capture plate 610. This avoids the situation where the surface of the capture plate 610 is covered with a lot of pollutants and the rotation speed remains unchanged, which would reduce the pollutant capture efficiency and improve the overall quality of use of the device.

[0033] The cleaning mechanism 7 includes an elastic telescopic rod 701, a buffer block 702, and a rotating plate 703. The elastic telescopic rod 701 is fixedly connected to the top of the protruding plate 9, the buffer block 702 is fixedly connected to the telescopic end of the elastic telescopic rod 701, and the rotating plate 703 is rotatably connected to the inner wall of the fixed block 602.

[0034] When the device is started, during the reciprocating lateral movement of the convex plate 9, the convex plate 9 will simultaneously drive the elastic telescopic rod 701 to move. The movement of the elastic telescopic rod 701 will drive the buffer block 702 to move. At the same time, the movement of the convex plate 9 will drive the fixed block 602 to move. The movement of the fixed block 602 will drive the rotating plate 703 to move. At this time, the rotating plate 703 can contact the discharged sewage during the reciprocating lateral movement. The rotating plate 703 can buffer and offset the impact force when the sewage is discharged. It can prevent the impact force of the water flow from being too large when too much sewage is discharged, which could damage the equipment parts inside the treatment tank 1 and improve the service life of the device.

[0035] The cleaning mechanism 7 also includes a fixed block 704, a horizontal slider 705, a connecting rod 706, a rotating column 707, a roller 708, and a scraper 709. The fixed block 704 is fixedly connected to the top of the activated carbon plate 606. The horizontal slider 705 is slidably connected to the inner wall of the top box 2. The connecting rod 706 is rotatably connected to the circumferential surface of the fixed block 704. The rotating column 707 is rotatably connected to the inner wall of the horizontal slider 705. The roller 708 is fixedly connected to the circumferential surface of the rotating column 707. The scraper 709 is fixedly connected to the circumferential surface of the rotating column 707. The buffer block 702 is in contact with the rotating plate 703, and the rotating plate 703 is used to buffer the discharged sewage. The connecting rod 706 is rotatably connected to the circumferential surface of the horizontal slider 705. The roller 708 is in contact with the filter plate 601. The scraper 709 is in contact with the filter plate 601, and the scraper 709 is used to push the debris on the surface of the filter plate 601 to move.

[0036] When the device is used for an extended period, the rising of the activated carbon plate 606 will cause the second fixed block 704 to rise, which in turn will cause the connecting rod 706 to rise. During this rise, the connecting rod 706 will simultaneously rotate, causing the horizontal slider 705 to slide laterally along the inner wall of the top box 2. The movement of the horizontal slider 705 will cause the second rotating column 707 to move, which in turn will cause the roller 708 to move. Simultaneously, the movement of the rotating column 707 will cause the scraper 709 to move. During the movement of the roller 708... During the process, the roller 708 generates motion friction due to contact with the filter plate 601. At this time, the roller 708 can rotate while moving. The rotation of the roller 708 will drive the rotating column 707 to rotate, and the rotation of the rotating column 707 will drive the scraper 709 to rotate. At this time, the scraper 709 will move and rotate at the same time. The scraper 709 can push the pollutants and debris on the surface of the filter plate 601, which can prevent the filter plate 601 from clogging due to long-term use, ensure the efficiency of sewage treatment, improve the self-cleaning ability of the device, and improve the sewage treatment efficiency of the device.

[0037] Overall working principle: The upward movement of the elastic telescopic rod 605 causes the activated carbon plate 606 to rise. At this time, the activated carbon plate 606 can move back and forth up and down, enhancing the contact efficiency between the activated carbon plate 606 and the wastewater, increasing the adsorption rate of the wastewater, and adsorbing odors from the wastewater. This improves the treatment quality of the wastewater. Simultaneously, the rotation of the capture plate 610 is slower than that of the rotating column 5, improving the pollutant capture efficiency of the capture plate 610. This avoids a situation where a large amount of pollutants are captured on the surface of the capture plate 610 while the rotation speed remains constant, leading to a decrease in pollutant capture efficiency. This improves the overall performance of the device. Plate 703 can contact the discharged sewage during reciprocating lateral movement. The rotating plate 703 can buffer and offset the impact force when sewage is discharged, and can prevent the impact force of the water flow from being too large when too much sewage is discharged, which could damage the equipment parts inside the treatment tank 1, thus improving the service life of the device. The rotation of the rotating column 707 will drive the scraper 709 to rotate. At this time, the scraper 709 will move and rotate at the same time. The scraper 709 can push the pollutants and debris on the surface of the filter plate 601, which can prevent the filter plate 601 from clogging due to long-term use, ensure the efficiency of sewage treatment, improve the self-cleaning ability of the device, and improve the sewage treatment efficiency of the device.
