Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to drainage system circulation devices. Background Technology

[0002] Cement hardens in air or water, firmly binding materials such as sand and stone together. After hardening, it not only has high strength but also resists erosion from both fresh and salt water. It is widely used in civil engineering, water conservancy, and national defense projects, with significant production demand. Meanwhile, cement plants, as enterprises with high water resource requirements, also generate substantial amounts of wastewater. With increasing water scarcity and severe pollution, people are paying more and more attention to wastewater purification and treatment.

[0003] Currently, traditional wastewater removal methods involve draining rainwater and sewage through pipes or pumping it into sedimentation tanks. However, the water in these tanks is easily evaporated by the sun, and the treatment effect is not very significant, only treating a portion of the water. This results in insufficient utilization of water resources and is inconsistent with the concept of sustainable development. Summary of the Invention

[0004] In order to improve the effectiveness of wastewater treatment, thereby conserving water resources and adhering to the concept of sustainable development, this application provides a drainage system circulation device.

[0005] The drainage system circulation device provided in this application adopts the following technical solution:

[0006] The drainage system circulation device includes an inlet pipe, a collection tank, a connecting pipe, and a collection tower. The inlet pipe is connected to the collection tank, and a primary filtration device is detachably connected inside the inlet pipe. A conduction pipe is connected to the side wall of the collection tank, and a secondary filtration device is installed inside the conduction pipe. The connecting pipe is connected to the secondary filtration device, and a tertiary filtration device is installed inside the connecting pipe. The connecting pipe is also connected to the collection tower.

[0007] By adopting the above technical solution, when rainwater and industrial wastewater enter the inlet pipe, they pass through a primary filtration device to remove larger particles of impurities. The wastewater, now free of larger particles, flows into a collection tank, which temporarily stores the wastewater and slows its flow. Subsequently, the wastewater flows from the collection tank into a transmission pipe, which reduces the likelihood of impurities adhering to the inner wall. The wastewater then passes through a secondary filtration device to remove finer impurities. Finally, the wastewater undergoes a tertiary filtration process in a connecting pipe to remove harmful microorganisms. The purified wastewater then flows into a collection tower for storage. The water in the collection tower is readily available for subsequent industrial use, such as for sprinkler systems at construction sites, supplying mixing plants, providing hydroponic tanks, and for environmental sanitation within the factory area. This improves wastewater treatment efficiency and conserves water resources. Therefore, it not only improves the construction environment but also solves the problem of muddy construction roads during the rainy season, while simultaneously reducing industrial water consumption and achieving sustainable development.

[0008] Preferably, the primary filtration device includes a first filter plate and a hinged door. The inner wall of the water inlet pipe is provided with an insertion groove, the first filter plate is inserted into the insertion groove, and the hinged door abuts against the first filter plate. A pushing component for pushing the first filter plate is provided in the insertion groove.

[0009] A sliding rod is fixedly installed inside the water inlet pipe, and a sliding groove is opened on the side wall of the first filter plate, allowing the first filter plate to slide on the sliding rod; a closed hole is opened on the side wall of the water inlet pipe for the first filter plate to slide out, and the hinge door is hinged to the inner wall of the closed hole, with a first torsion spring installed on the hinge door; a fixing component for fixing the hinge door is installed on the hinge door.

[0010] By adopting the above technical solution, when sewage flows into the primary filtration device through the inlet pipe, the sewage will pass through the filter holes on the first filter plate. Larger impurities will be trapped on the surface of the first filter plate. When too many impurities accumulate on the first filter plate, the fixing component on the hinge door is released, the hinge door opens, and the first filter plate slides out of the inlet pipe along the slide rod under the action of the pushing component. This makes it easier for staff to clean the debris on the first filter plate and solve the problem of impurity blockage. After the first filter plate is cleaned, the staff aligns the slide groove on the first filter plate with the slide rod, pushes the first filter plate and inserts it into the insertion slot, and then closes the hinge door to continue filtering sewage.

[0011] Preferably, the hinged door has a placement groove, the fixing component is disposed in the placement groove, the fixing component includes a fixing block and a first spring, the fixing block has an inclined surface, the fixing block is slidably connected to the inner wall of the placement groove, the two ends of the first spring are respectively fixedly disposed on the fixing block and the inner wall of the placement groove, and the inner wall of the closed hole has a fixing hole for the fixing block to be inserted.

[0012] By adopting the above technical solution, when the worker pushes the hinged door to close, the inclined surface of the fixing block abuts against the inner wall of the sealing hole and pushes the fixing block to compress the first spring and move into the placement groove. When the hinged door is fully closed, the fixing block corresponds to the fixing hole on the inner wall of the sealing hole, so that the fixing block is inserted into the fixing hole under the push of the first spring, thereby reducing the possibility of the hinged door rotating.

[0013] Preferably, a rubber pad is fixedly adhered to the side wall of the hinged door, and the rubber pad abuts against the closed hole.

[0014] By adopting the above technical solution, when the hinged door is closed, the rubber pad abuts against the inner wall of the sealed hole, thereby reducing the possibility of sewage leakage from the inlet pipe.

[0015] Preferably, the inner wall of the water inlet pipe is provided with a placement groove, and a rotating rod is rotatably connected to the inner wall of the placement groove. A baffle plate is fixedly installed on the rotating rod, and a second torsion spring is fixedly sleeved on the rotating rod. A driving assembly for driving the baffle plate to rotate is provided in the placement groove. A support groove for placing the baffle plate is provided on the inner wall of the water inlet pipe opposite to the baffle plate, and a limiting assembly for limiting its own position is provided on the baffle plate.

[0016] By adopting the above technical solution, when the first filter plate becomes clogged, the baffle plate rotates under the drive of the drive assembly, overcoming the elastic force of the second torsion spring. When the baffle plate rotates to a horizontal state, the end of the baffle plate away from the rotating rod abuts against the inner wall of the support groove. Under the action of the limiting assembly, the baffle plate is fixed in a horizontal state. At this time, the water flow in the inlet pipe is cut off, which facilitates the cleaning of the first filter plate and reduces the possibility of sewage leakage outside the inlet pipe.

[0017] Preferably, the inner wall of the water inlet pipe is provided with a power groove, and the drive assembly includes a turntable and a rack. The turntable is fixedly sleeved on the rotating rod, and the rack is slidably connected to the inner wall of the power groove.

[0018] The turntable is provided with multiple toothed blocks, one side of which is hinged to the toothed disk and the other side abuts against the toothed disk, and the rack meshes with the toothed block;

[0019] The water collection tank is equipped with a float plate, and a traction rope is fixedly connected to the float plate. One end of the traction rope is fixedly connected to the rack.

[0020] By adopting the above technical solution, when the first filter plate becomes clogged, the water flow rate from the inlet pipe through the first-stage filtration into the water collection tank will decrease, creating a gap with the water flow rate from the water collection tank to the conduction pipe. When the water level in the water collection tank drops, the float plate will also drop in position. During the descent of the float plate, the position of the traction rope will also decrease. When the water level drops to a certain position, the traction rope will be stretched, thereby pulling the rack to move. When the rack moves, since one end of the tooth block abuts against the turntable, the rack drives the turntable to rotate through the tooth block. The rotation of the turntable drives the rotating rod to rotate, and the rotation of the rotating rod drives the baffle plate to rotate to the horizontal direction.

[0021] Preferably, a pulley is fixedly installed inside the power groove, and the traction rope slides on the side wall of the pulley.

[0022] By adopting the above technical solution, the traction rope drives the rack to move horizontally under the guidance of the pulley, reducing the possibility of rack position displacement caused by changes in force direction when the traction rope is stretched. At the same time, it reduces the friction between the traction rope and the inner wall of the power groove.

[0023] Preferably, a second spring is fixedly installed inside the power groove, and the two ends of the second spring are respectively fixedly connected to the rack and the inner wall of the power groove.

[0024] By adopting the above technical solution, when the water level in the collection tank rises, the float rises, and the traction rope loses its tension on the rack. At this time, the rack moves towards the reset plate under the elastic force of the third spring. During the movement of the rack, the teeth on the rack push the tooth block to rotate, so there is no meshing between the rack and the tooth block, which facilitates the reset of the rack. At the same time, the movement of the rack has no effect on the turntable, and the reset of the rack does not affect the state of the baffle plate.

[0025] Preferably, the baffle plate has a storage groove, and the limiting component includes a limiting block, a pushing block, and a third spring; the pushing block is fixedly disposed on the side wall of the baffle plate and inserted into the fixing hole; the limiting block is slidably connected to the inner wall of the storage groove, and the two ends of the third spring are respectively fixedly connected to the limiting block and the inner wall of the storage groove, and the inner wall of the support groove has a limiting groove for the limiting block to be inserted.

[0026] When the baffle plate rotates to the support groove, the push block on the baffle plate can be inserted into the fixing hole and push the fixing block to compress the first spring and move into the placement groove. The limiting block is inserted into the limiting groove under the force of the third spring, thereby reducing the rotation of the baffle plate under the force of the second torsion spring. At the same time, the fixing block moves away from the fixing hole, and the hinged door is opened under the force of the second torsion spring.

[0027] Preferably, a push plate slides within the limiting groove, and a push rod is fixedly mounted on the push plate, the push rod passing through and sliding within the limiting groove.

[0028] By adopting the above technical solution, when the worker inserts the cleaned first filter plate into the insertion slot, the worker pushes the hinged door to rotate to the vertical position. At this time, the worker pushes the push rod, which pushes the push plate to move. The push plate moves and pushes the limit block to compress the fourth spring and move into the storage slot. When the limit block leaves the limit slot, the baffle plate rotates to the vertical position under the elastic force of the second torsion spring. At the same time as the baffle plate rotates away, the push block moves away from the fixing hole, and the fixing block inserts into the fixing hole to fix the hinged door.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. When rainwater and industrial wastewater enter the inlet pipe, they pass through a primary filtration device to remove larger particles. The wastewater, now free of larger particles, flows into a collection tank, which temporarily stores the wastewater and slows its flow. The wastewater then flows into a transmission pipe, which reduces the likelihood of impurities adhering to its inner wall. A secondary filtration device removes finer impurities. The wastewater then undergoes a tertiary filtration process in a connecting pipe to remove harmful microorganisms. Finally, the purified wastewater flows into a collection tower for storage. The water in the collection tower is readily available for subsequent industrial use, such as for sprinkler systems at construction sites, supplying mixing plants, providing hydroponic tanks, and for environmental sanitation within the factory area. This improves wastewater treatment efficiency and conserves water resources. Therefore, it not only improves the construction environment but also solves the problem of muddy construction roads during the rainy season, while simultaneously reducing industrial water consumption, thus achieving sustainable development.

[0031] 2. When sewage flows into the primary filtration device through the inlet pipe, it passes through the filter holes on the first filter plate. Larger impurities are trapped on the surface of the first filter plate. When too much impurity accumulates on the first filter plate, the fixing component on the hinge door is released, the hinge door opens, and the first filter plate slides out of the inlet pipe along the slide rod under the action of the pushing component. This makes it easier for staff to clean the debris on the first filter plate and solve the problem of impurity blockage. After the first filter plate is cleaned, the staff aligns the sliding groove on the first filter plate with the slide rod, pushes the first filter plate and inserts it into the insertion groove, and then closes the hinge door to continue filtering sewage.

[0032] 3. Under the guidance of the pulley, the traction rope drives the rack to move horizontally, reducing the possibility of rack displacement caused by changes in force direction when the traction rope is stretched. At the same time, it reduces the friction between the traction rope and the inner wall of the power groove. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses a drainage system circulation device, such as... Figure 1As shown, the system includes an inlet pipe 1, a collection tank 2, a connecting pipe 3, and a collection tower 4. The inlet pipe 1 is connected to the collection tank 2, and a primary filter is detachably connected inside the inlet pipe 1. The primary filter removes larger impurities from the wastewater flowing through the inlet pipe 1, and the wastewater after primary filtration flows into the collection tank 2. The collection tank 2 temporarily stores wastewater and is equipped with a power pump to power the water flow. A conduction pipe 8 is connected to the side wall of the collection tank 2. The conduction pipe 8 reduces the adhesion of small impurities in the wastewater to the inner wall of the pipe under the action of reagents in the wastewater, thereby reducing the possibility of pipe blockage. A secondary filter is installed inside the conduction pipe 8. The system includes a filtration device; a secondary filtration device connected to connecting pipe 3, which filters out smaller impurities from the wastewater. The wastewater after secondary filtration generally meets the water requirements of the factory. Connecting pipe 3 connects to the secondary filtration device, and a tertiary filtration device within it disinfects the wastewater, removing harmful bacteria. Industrial water and rainwater from the cement plant undergo three stages of filtration driven by a power pump and are then stored in a collection tower 4. The water in collection tower 4 is readily available for subsequent industrial use, such as for sprinkler systems at construction sites, supplying the mixing plant, providing water to the curing tank, and for environmental sanitation within the factory area. This three-stage filtration improves wastewater treatment efficiency, thereby conserving water resources. Therefore, it not only improves the construction environment but also solves the problem of mud-filled construction roads during the rainy season, while simultaneously reducing industrial water consumption, thus achieving sustainable development.

[0041] like Figure 2 and Figure 3 As shown, the primary filtration device includes a first filter plate 9 and a hinged door 10; a closed hole 15 is provided on the side wall of the water inlet pipe 1, the bottom end of the hinged door 10 is hinged to the inner wall of the closed hole 15, and a first torsion spring 16 is provided inside the hinged door 10; the hinged door 10 is in a horizontal state under the action of the first torsion spring 16; a rubber pad 22 is fixedly adhered to the peripheral side wall of the hinged door 10, and the rubber pad 22 abuts against the closed hole 15; a fixing component 17 for fixing the hinged door 10 is provided on the hinged door 10.

[0042] like Figure 2 and Figure 3 As shown, the inner wall of the water inlet pipe 1 is provided with a plug groove 11, and a pushing component 12 is provided in the plug groove 11. The pushing component 12 includes a pressing block and a plurality of fourth springs 45. The pressing block 46 is slidably connected to the inner wall of the plug groove 11 in the horizontal direction. The fourth springs 45 are arranged in the horizontal direction and their two ends are respectively fixedly connected to the side wall of the pressing block 46 and the inner wall of the plug groove 11. The lower end face of the first filter plate 9 is provided with a sliding groove 14 in the horizontal direction. A sliding rod 13 is fixedly provided in the water inlet pipe 1, and the two ends of the sliding rod 13 are respectively fixedly provided to the opposite inner wall of the water inlet pipe 1. The first filter plate 9 slides in the horizontal direction on the sliding rod 13, and the hinged door 10 abuts against the first filter plate 9.

[0043] like Figure 2 and Figure 3 As shown, the upper side wall of the hinged door 10 has a vertically oriented placement groove 18. The fixing component 17 is disposed in the placement groove 18. The fixing component 17 includes a fixing block 19 and a first spring 20. The fixing block 19 has an inclined surface. The first spring 20 is vertically oriented. The two ends of the first spring 20 are respectively fixedly welded to the lower end face of the fixing block 19 and the inner wall of the placement groove 18. The top inner wall of the closed hole 15 has a fixing hole 21 for the fixing block 19 to be inserted.

[0044] like Figure 2 and Figure 3 As shown, a placement groove 24 is provided on the upper part of the inner wall opposite to the hinged door 10 of the water inlet pipe 1. A rotating rod 23 is rotatably connected to the placement groove 24 relative to the inner wall. A baffle plate 25 is fixedly welded to the rotating rod 23. A second torsion spring 26 is provided on the rotating rod 23. A drive assembly 27 for driving the baffle plate 25 to rotate is provided in the placement groove 24. A support groove 28 is provided on the inner wall of the water inlet pipe 1 located at the upper end of the hinged door 10, which allows the baffle plate 25 to be placed. The baffle plate 25 can abut against the inner wall of the support groove 28. A limiting assembly 29 for limiting its own position is provided on the baffle plate 25.

[0045] like Figure 3 and Figure 4 As shown, a power groove 44 is provided on the inner wall of the water inlet pipe 1, and the rotating rod 23 passes through the inner wall of the power groove 44; the drive assembly 27 includes a turntable 30 and a rack 31, the rack 31 is slidably connected to the inner wall of the power groove 44 in the horizontal direction; the turntable 30 is fixedly sleeved on the rotating rod 23, and a plurality of tooth blocks 32 are fixedly welded on the turntable 30, one side of the bottom end face of the tooth block 32 is hinged to the tooth disc, and the other side abuts against the tooth disc, and the rack 31 meshes with the tooth block 32;

[0046] A float plate 33 is installed inside the water collection tank 2, and a traction rope 34 is fixedly connected to the float plate 33. One end of the traction rope 34 is fixedly connected to the rack 31. A fixed rod is fixedly welded to the inner wall of the power channel 44, and a pulley 35 rotates on the fixed rod. The traction rope 34 slides on the side wall of the pulley 35. A second spring 36 is fixedly installed inside the placement slot 18. The second spring 36 is arranged in a horizontal direction, and its two ends are fixedly welded to the rack 31 and the inner wall of the power channel 44, respectively.

[0047] like Figure 2 and Figure 3As shown, a storage groove 37 is vertically formed on the upper end face of the baffle plate 25. The limiting component 29 includes a limiting block 38, a pushing block 39, and a third spring 40. The pushing block 39 is fixedly welded to the side wall of the baffle plate 25 and can be inserted into the fixing hole 21. An inclined surface is formed on the limiting block 38, and the limiting block 38 is slidably connected to the inner wall of the storage groove 37 in the vertical direction. The third spring 40 is vertically arranged, and its two ends are fixedly welded to the limiting block 38 and the inner wall of the storage groove 37, respectively. A limiting groove 41 is formed on the inner wall of the support groove 28 for the limiting block 38 to be inserted. A push plate 42 slides in the limiting groove 41 and abuts against the limiting block 38. A push rod 43 is fixedly set on the push plate 42 and slides through the side wall of the water inlet pipe 1.

[0048] like Figure 2 and Figure 3 As shown, and in combination Figure 4 As shown, when sewage flows through the inlet pipe 1 to the primary filtration device, the sewage passes through the filter holes on the first filter plate 9. Larger impurities are trapped on the surface of the first filter plate 9. When too many impurities accumulate on the first filter plate 9, it will affect the flow rate of the first filter plate 9. The water flow through the first filter plate 9 will gradually decrease, creating a gap with the water flow rate from the collection tank 2 to the conduction pipe 8. The water level drops, and the float 33 follows the drop in water level and lowers its position. When the float 33 is at a certain height, the traction rope 34 is stretched. Under the action of the pulley 35, the stretched traction rope 34 can pull the rack 31 to move in the horizontal direction. At the same time, the pulley 35 can reduce the friction of the traction rope 34 against the inner wall of the power groove 44. When the rack 31 moves, the rack 31 meshes with the toothed block 32 on the turntable 30. Therefore, the movement of the rack 31 drives the turntable 30 to rotate. The rotation of the turntable 30 drives the rotating rod 23 to rotate. The rotation of the rotating rod 23 drives the baffle plate 25 to rotate in the horizontal direction.

[0049] like Figure 2 and Figure 3As shown, during the process of the baffle plate 25 rotating to a horizontal state and abutting against the inner wall of the support groove 28, when the baffle plate 25 contacts the inner wall of the support groove 28, under the action of the inclined surface on the limiting block 38, as the baffle plate 25 moves, the limiting block 38 compresses the third spring 40 under the squeezing of the inner wall of the support groove 28 and moves into the storage groove 37; when the baffle plate 25 is about to be horizontal, the push block 39 abuts against the fixing block 19 on the hinge door 10 and pushes the fixing block 19 to compress the first spring 20 and move into the placement groove 18. At the same time, the push block 39 is inserted into the fixing hole 21. When the push block 39 is fully inserted into the fixing hole 21, the fixing block 19 moves away from the fixing hole 21. Fixed hole 21; at this time, the hinged door 10 is pushed to rotate to the horizontal direction under the elastic force of the first torsion spring 16; when the baffle plate 25 is horizontal, the storage tank 37 is aligned with the limiting groove 41, and the limiting block 38 is pushed by the elastic force of the third spring 40 to push the push plate 42 and insert it into the limiting groove 41, the baffle plate 25 is fixed, the baffle plate 25 cuts off the water flow in the water inlet pipe 1, and reduces the leakage of sewage when cleaning the first filter plate 9; at the moment the hinged door 10 is opened, the abutment block 46 is pushed by the elastic force of the fourth spring 45 to slide the first filter plate 9 out of the water inlet pipe 1, which makes it convenient for the staff to clean the first filter plate 9.

[0050] like Figure 2 and Figure 3 As shown, after the first filter plate 9 is cleaned, the staff aligns the sliding groove 14 on the first filter plate 9 with the sliding rod 13, pushes the first filter plate 9 to abut against the abutment block 46 and compress the fourth spring 45, and inserts it into the insertion groove 11. Then the staff closes the hinge door 10, and the side wall of the hinge door 10 abuts against the side wall of the first filter plate 9. During the process of the staff pushing the hinged door 10 to close, the inclined surface of the fixing block 19 abuts against the inner wall of the sealing hole 15, and pushes the fixing block 19 to compress the first spring 20 and move into the placement groove 18. When the hinged door 10 is completely closed, the rubber pad 22 abuts against the inner wall of the sealing hole 15, thereby reducing the possibility of sewage leakage in the water inlet pipe 1. The fixing block 19 corresponds to the fixing hole 21 on the sealing hole 15. Subsequently, the staff pushes the push rod 43 to move into the water inlet pipe 1. The movement of the push rod 43 pushes the push plate 42 to move. The movement of the push plate 42 pushes the limit block 38 to compress the third spring 40. When the limit block 38 disengages from the limit groove 41, the baffle plate 25 rotates to a vertical state under the elastic force of the second torsion spring 26. When the baffle plate 25 rotates, the push block 39 moves away from the fixing hole 21. At the same time, the fixing block 19 is pushed into the fixing hole 21 by the first spring 20, thereby reducing the possibility of the hinged door 10 rotating.

[0051] like Figure 2 and Figure 3As shown, when the water level in the collection tank 2 rises, the float 33 rises, and the traction rope 34 loses its tension on the rack 31. At this time, the rack 31 moves away from the pulley 35 under the elastic force of the second spring 36. During the movement of the rack 31, when the teeth on the rack 31 abut against the tooth block 32, the hinged end of the tooth block 32 rotates. Thus, there is no meshing between the rack 31 and the tooth block 32. Therefore, when the rack 31 moves, the baffle plate 25 has no driving effect. Thus, the reset of the rack 31 does not affect the state of the baffle plate 25.

[0052] like Figure 2 and Figure 3 As shown, and in combination Figure 4 As shown, during the sewage filtration process, if too many impurities accumulate on the first filter plate 9 and cause blockage, affecting the filtration effect, the baffle plate 25 will automatically pop out to isolate the sewage. Subsequently, the hinged door 10 will open, and the first filter plate 9 will be popped out, reminding the staff to clean the first filter plate 9, thereby reducing the possibility of pipe blockage and increasing the sewage filtration efficiency.

[0053] The implementation principle of this application embodiment is as follows: Industrial water and rainwater generated in the factory are collected into the inlet pipe 1. Larger impurities are filtered out when the water passes through the primary filtration device. Subsequently, smaller impurities are filtered out through the secondary filtration device. Finally, the water is disinfected through the tertiary filtration device. Finally, the filtered water is transported to the water collection tower 4 for storage, providing industrial water for the factory. This not only saves water resources but also improves the construction environment and solves the problem of muddy construction roads in the construction area during the rainy season. It also reduces the amount of industrial water used, thus realizing the concept of sustainable development.

[0054] Because the primary filtration device filters larger impurities, it is relatively large in size and prone to accumulation. Therefore, this application provides a detachable first filter plate 9. When the float plate 33 detects that the first filter plate 9 is blocked, the drive assembly 27 drives the baffle plate 25 to rotate to the horizontal direction to intercept the flow in the inlet pipe 1. Subsequently, the hinged door 10 opens, and the first filter plate 9 is pushed out of the inlet pipe 1 by the push assembly 12, which makes it easier for staff to clean the first filter plate 9 and thus improves the filtration effect.

[0055] 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.
