Description

Technical Field

[0001] The present application relates to the technical field of wastewater recycling, and in particular to a building wastewater self-treatment and recycling system. Background Art

[0002] During the construction process of construction projects, a large amount of construction wastewater will be generated. The wastewater will contain a large amount of construction debris, including various heavy metals, trace amounts of highly toxic organic matter (PCBs, AOX, etc.), pathogenic microorganisms, etc. Direct discharge will cause environmental hygiene and pollution problems, so these construction wastewaters need to be treated.

[0003] Currently, patent publication number CN211245687U discloses a construction wastewater recycling device. The device includes a base frame, a support frame, and a wastewater tank. A top cover is threadedly connected to one side of the wastewater tank. A ring plate is fixedly connected to the middle of the inner wall of the wastewater tank.

One end of the water pipe is fixedly connected to the recovery tank. An outlet pipe is fixedly connected to one side of the bottom of the recovery tank. However, when using this device to filter construction wastewater, the filter residue on the first filter screen will block the filter holes, thereby hindering the subsequent filtration operation and significantly reducing the filtration and purification efficiency of the wastewater. Utility Model Content

[0004] In order to clean the filter residue on the filter screen and improve the filtration and purification efficiency of wastewater, the present application provides a building wastewater self-treatment and recycling system.

[0005] This application provides a technical solution that adopts the following:

[0006] A building wastewater self-treatment and recycling system includes a wastewater tank and a water storage tank, the wastewater tank and the water storage tank are connected, a filter plate is slidably arranged in the wastewater tank, a first through groove for the filter plate to slide is provided on the side wall of the wastewater tank, a cleaning component is provided in the wastewater tank, the cleaning component includes a scraper block, the bottom surface of the scraper block is provided with scraping bristles, the scraping bristles abut the surface of the filter plate, a collection frame is slidably arranged in the wastewater tank, the collection frame is located below the filter plate, and a second through groove for the collection frame to pass through is provided on the side wall of the wastewater tank.

[0007] By adopting the above technical solution, when there is too much filter residue accumulated on the filter plate, the worker pulls the filter plate toward the outside of the wastewater tank. During the sliding process of the filter plate, the scraper pushes the filter residue accumulated on the filter plate into the collection frame. After cleaning, the worker pushes the filter plate back into the wastewater tank for filtration, and at the same time pulls the collection frame out of the wastewater to the top of the water storage tank to avoid the collection frame affecting the subsequent filtration process. This arrangement realizes the cleaning of the filter residue on the surface of the filter plate, reduces the possibility of excessive filter residue blocking the filter holes, thereby ensuring the smooth progress of subsequent filtration operations and improving the filtration and purification efficiency of wastewater.

[0008] In a specific feasible implementation scheme, a support frame is provided in the wastewater tank, the support frame is sleeved on the outside of the filter plate and overlaps with the filter plate, the outer wall of the support frame is in contact with the inner wall of the wastewater tank, and a first groove is provided on the opposite side walls of the wastewater tank, a rack is provided in the first groove, and a second groove is provided on the opposite side walls of the support frame, each of the second grooves is rotatably connected to a gear meshing with the rack, and a first motor that drives the gear to rotate is provided on the outer wall of the support frame.

[0009] By adopting the above technical solution, when too much filter residue accumulates on the filter plate, the first motor starts to drive the gear to rotate forward. During the rotation of the gear, it will move along the length direction of the rack. The movement of the gear drives the support frame to move, and the support frame drives the filter plate to gradually move toward the first through groove. When the rack moves to one end of the rack close to the first through groove, the filter plate is completely moved out of the wastewater tank, and the filter residue on the surface of the filter plate is cleaned. At this time, the first motor drives the gear to rotate in the opposite direction, and the gear drives the filter plate to move toward the inside of the wastewater tank. This arrangement realizes the automatic operation of the filter plate movement, eliminating the operation of manually pulling the filter plate.

[0010] In a specific possible implementation scheme, a first magnet is provided on the support frame, and a second magnet is provided on the filter plate at a position corresponding to the first magnet, and the first magnet and the second magnet are attracted to each other.

[0011] By adopting the above technical solution, a detachable connection between the filter plate and the support frame is achieved through the adsorption effect between the first magnet and the second magnet. This arrangement makes it convenient for workers to remove the filter plate directly from the support frame and replace it when the filter plate is damaged or needs to be replaced with a filter plate of a different specification, thereby ensuring the filtering effect of the filter plate and improving the filtration and purification efficiency of wastewater.

[0012] In a specific possible implementation scheme, one end of the support frame close to the first through groove is arranged to be inclined upward from the surface of the filter plate along a direction away from the center of the support frame, and the other end is arranged to be inclined downward from the surface of the filter plate along a direction away from the center of the support frame, and the scraper block is a wedge-shaped block.

[0013] By adopting the above technical solution, a height difference is formed between the end of the support frame close to the first through groove and the surface of the filter plate, which effectively ensures the filtering effect of the filter plate and prevents wastewater from falling on the surface of the support frame. At the same time, the inclined surface can make the filter residue roll to the surface of the filter plate under the action of gravity, preventing the filter residue from escaping from the wastewater tank through the first through groove. The inclined surface at the other end of the support frame forms a guiding inclined surface for the filter residue to pass through the collection frame. Under the guidance of the inclined surface, the filter residue is smoothly scraped into the collection frame, effectively avoiding the accumulation of filter residue on the surface of the filter plate.

[0014] In a specific possible implementation scheme, a third groove is provided on one side wall of the wastewater tank along the height direction of the wastewater tank, and the cleaning assembly also includes a threaded rod rotatably arranged in the third groove, a second motor is provided on the wastewater tank, and the output shaft of the second motor is coaxially connected to the threaded rod, a connecting block is threadedly connected to the threaded rod, and the end of the scraping block away from the scraping is connected to the scraping block.

[0015] By adopting the above technical solution, when the filter residue on the filter plate needs to be cleaned, the second motor drives the threaded rod to rotate forward, and the threaded rod drives the scraper block to move toward the filter plate through the connecting block until the bristles abut against the surface of the filter plate. When the filter residue is cleaned, the second motor drives the threaded rod to rotate in the opposite direction, and the threaded rod drives the scraper block away from the filter plate until the end of the bristles moves above the opening of the first through groove, thereby avoiding the scraper block from affecting the resetting process of the filter plate, thereby ensuring the normal operation of the subsequent filtration work of the cleaned filter plate.

[0016] In a specific possible implementation scheme, a placement groove is provided on the bottom wall of the second through groove, and a limit assembly is provided in the placement groove. The limit assembly includes a fixed rod connected to the bottom wall of the placement groove, and a reset spring is provided on the outer side of the fixed rod. One end of the reset spring is connected to the bottom wall of the placement groove, and the other end is connected to a limit block. The fixed rod is inserted into the limit block and slidably cooperates with the limit block. When the reset spring is in a natural state, the limit block extends out of the placement groove and contacts the outer surface of the collection frame.

[0017] By adopting the above technical solution, during the process of collecting filter residue by the collecting frame, the collecting frame will be subjected to the force of filter residue from different directions inside the wastewater tank, and the limit block will contact the outer surface of the collecting frame under the action of the reset spring, which can limit the collecting frame and prevent the collecting frame from being displaced inside the wastewater tank and detached from the wastewater tank when subjected to uneven force. This ensures the stability of the process of collecting filter residue by the collecting frame, reduces the probability of filter residue not being collected and directly entering the water storage tank, thereby further improving the filtration and purification efficiency of wastewater.

[0018] In a specific embodiment, the cross section of the limiting block is trapezoidal.

[0019] By adopting the above technical solution, in the process of pushing the collecting frame into the interior of the wastewater tank, under the guidance of the inclined surface of the limit block, the collecting frame squeezes the limit block, and the limit block compresses the reset spring and slides into the placement slot along the fixed rod. When the end face of the collecting frame hits the inner wall of the wastewater tank, the pressure on the reset spring disappears, and the reset spring pushes the limit block to hit the outer surface of the collecting frame, thereby limiting the collecting frame; when the collecting frame is collected and needs to be taken out, the worker pulls the collection frame outward, and the worker's pulling force overcomes the elastic force of the reset spring to make the limit block slide into the placement slot again. At this time, the collection frame slides out of the wastewater tank, and the trapezoidal design of the limit block makes the pushing and pushing out process of the collecting frame smoother, thereby ensuring the smooth progress of cleaning the filter residue and filtering process.

[0020] In a specific possible implementation scheme, an annular groove is provided on the inner wall of the waste water tank, and the annular groove is connected to the second through groove; a pressure sensor is provided on the bottom wall of the annular groove away from the second through groove, and the pressure sensor is electrically connected to the second motor.

[0021] By adopting the above technical solution, when the end face of the collection frame touches the pressure sensor, the pressure sensor receives the pressure signal and transmits it to the second motor. The second motor drives the scraper to move toward the filter plate, and the filter residue cleaning work begins. The setting of the pressure sensor realizes the automatic operation of the filter residue cleaning work, reduces the steps of manual operation, and improves the efficiency of cleaning the filter residue.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application sets a cleaning component and a collection frame. During the movement of the filter plate, the scraper pushes the filter residue accumulated on the filter plate into the collection frame. After cleaning, the worker pushes the filter plate back into the wastewater tank for filtration, and at the same time, the collection frame is pulled out of the wastewater to the top of the water storage tank to prevent the collection frame from affecting the subsequent filtration process. This arrangement realizes the cleaning of the filter residue on the surface of the filter plate, reduces the possibility of excessive filter residue blocking the filter holes, thereby ensuring the smooth progress of subsequent filtration operations and improving the filtration and purification efficiency of wastewater;

[0024] 2. The present application sets a limit assembly, and the limit block contacts the outer surface of the collection frame under the action of the reset spring, which can limit the collection frame and prevent the collection frame from being displaced inside the wastewater tank and detached from the wastewater tank when subjected to uneven force. This ensures the stability of the collection frame in the process of collecting filter residue, reduces the probability of the filter residue not being collected and directly entering the water storage tank, thereby further improving the filtration and purification efficiency of wastewater.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a building wastewater self-treatment and recycling system.

[0034] Reference Figure 1 A building wastewater self-treatment and recycling system includes a wastewater tank 01, an inlet pipe 9, an outlet pipe 8 and a water storage tank 02. The wastewater tank 01 and the water storage tank 02 are connected by a connecting pipe 6. The inlet pipe 9 is located above the wastewater tank 01 and is connected to the inside of the wastewater tank 01. The water inlet end of the inlet pipe 9 is connected to the wastewater pipe. The outlet pipe 8 is located below the wastewater tank 01 and is connected to the wastewater tank 01. A water stop valve 7 is installed on both the connecting pipe 6 and the outlet pipe 8.

[0035] Reference Figure 1 、 Figure 2 and Figure 3The filter plate 1 and the support frame 3 are slidingly connected inside the wastewater tank 01. The support frame 3 is sleeved on the outer surface of the filter plate 1 and overlapped with the outer surface. The outer surface of the support frame 3 fits the inner wall of the wastewater tank 01. The opposite side walls of the wastewater tank 01 are provided with a first groove 013, and a rack 0131 is fixedly connected in each first groove 013. The length direction of the rack 0131 is parallel to the length direction of the first groove 013. Second grooves 31 are provided on the opposite outer walls of the support frame 3, and a gear 311 that is meshed with the rack 0131 is rotatably connected in each second groove 31. The bottom surface of the support frame 3 is fixedly connected to a first motor (not shown in the figure), and the output shaft of the first motor is coaxially fixedly connected to the gear 311.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 A collecting frame 2 is slidably connected above the water storage tank 02, and a gripper 21 is fixedly connected to the side of the collecting frame 2 away from the waste water tank 01. A second through slot 012 that slides with the collecting frame 2 is provided on the waste water tank 01. The second through slot 012 is located below the first through slot 011, and the second through slot 012 is connected to the interior of the waste water tank 01. The sliding mode of the collecting frame 2 on the water storage tank 02 of this embodiment takes the sliding cooperation of the slide rail and the slider as an example. When the collecting frame 2 moves to the inside of the waste water tank 01 through the second through slot 012, the collecting frame 2 is located directly below the filter plate 1.

[0037] Reference Figure 3 and Figure 6 A third groove 014 is provided on the side wall of the wastewater tank 01, and the length direction of the third groove 014 is parallel to the height direction of the wastewater tank 01. A cleaning assembly is provided inside the wastewater tank 01, and the cleaning assembly includes a threaded rod 41 rotatably connected to the third groove 014. The top surface of the wastewater tank 01 is fixedly connected to a second motor 45, and the output shaft of the second motor 45 is coaxially and fixedly connected to the threaded rod 41. A connecting block 42 is threadedly connected to the threaded rod 41, and a scraping block 43 is fixedly connected to the bottom surface of the connecting block 42. A plurality of scraping bristles 44 are fixedly connected to the bottom surface of the scraping block 43, and the scraping bristles 44 abut against the surface of the filter plate 1.

[0038] Reference Figure 3 and Figure 6 An annular groove 015 is formed at one end of the wastewater tank 01 away from the first through groove 011 , and a pressure sensor 0151 is fixedly connected in the annular groove 015 . The pressure sensor 0151 is electrically connected to the second motor 45 through the control system.

[0039] When too much filter residue accumulates on the filter plate 1, the worker pushes the collection frame 2 into the wastewater tank 01. When the end surface of the collection frame 2 touches the pressure sensor 0151, the sensor 0151 receives the pressure signal and transmits it to the second motor 45. The second motor 45 drives the threaded rod 41 to rotate forward. The threaded rod 41 drives the scraper 43 to move toward the filter plate 1 through the connecting block 42 until the scraper 44 abuts against the surface of the filter plate 1. Then the first motor starts to drive the gear 311 to rotate forward. During the rotation of the gear 311, it will move along the length direction of the rack 0131. The movement of the gear 311 drives the support frame 3 to move, and the support frame 3 drives the filter plate 1 to gradually move toward the first through groove 011. During the sliding process of the filter plate 1, the scraper 44 pushes the filter residue accumulated on the filter plate 1 into the collection frame 2. This arrangement realizes the cleaning of the filter residue on the surface of the filter plate 1, reduces the possibility of excessive filter residue blocking the filter holes, thereby ensuring the smooth progress of subsequent filtration operations and improving the filtration and purification efficiency of wastewater.

[0040] After cleaning is completed, the second motor 45 drives the threaded rod 41 to rotate in the opposite direction, and the threaded rod 41 drives the scraper 43 away from the filter plate 1 until the end of the scraper 44 moves above the opening of the first through groove 011 to prevent the scraper 43 from affecting the resetting process of the filter plate 1. Then the first motor drives the gear 311 to rotate in the opposite direction, and the gear 311 drives the filter plate 1 to move toward the inside of the wastewater tank 01. After the filter plate 1 completely enters the wastewater tank 01, the collection frame 2 is drawn out of the wastewater to above the water storage tank 02 to prevent the collection frame 2 from affecting the subsequent filtration process.

[0041] Reference Figure 3 and Figure 6 The end of the support frame 3 close to the first through groove 011 is inclined upward from the surface of the filter plate 1 in the direction away from the center of the support frame 3. The scraper block 43 is a wedge-shaped block to adapt to the inclined surface of the support frame 3. The end of the support frame 3 close to the first through groove 011 forms a height difference with the surface of the filter plate 1, which effectively ensures the filtering effect of the filter plate 1 and prevents the wastewater from falling on the surface of the support frame 3. At the same time, the inclined surface can make the filter residue roll to the surface of the filter plate 1 under the action of gravity, preventing the filter residue from leaving the wastewater tank 01 through the first through groove 011.

[0042] Reference Figure 3 and Figure 6 The end of the support frame 3 away from the first through groove 011 is tilted downward from the surface of the filter plate 1 in a direction away from the center of the support frame 3. The inclined surface forms a guiding inclined surface for the filter residue to pass through the collecting frame 2. Under the guidance of the inclined surface, the filter residue is smoothly scraped into the collecting frame 2, effectively avoiding the accumulation of filter residue on the surface of the filter plate 1.

[0043] Reference Figure 3 and Figure 6A plurality of second magnets 11 are fixedly connected to the support frame 3 , and a second magnet 11 corresponding to the second magnet 11 is fixedly connected to the bottom surface of the filter plate 1 . The second magnet 11 is located directly above the first magnet 32 ​​and is attracted to the first magnet 32 ​​.

[0044] When the filter plate 1 is damaged or needs to be replaced with a filter plate 1 of different specifications, the filter plate 1 is directly taken out from the support frame 3 and replaced, thereby ensuring the filtering effect of the filter plate 1 and improving the filtering and purification efficiency of the wastewater.

[0045] Reference Figure 3 and Figure 4 In the process of collecting the filter residue by the collection frame 2, the collection frame 2 will be subjected to the force of the filter residue from different directions inside the wastewater tank 01. At this time, the collection frame 2 will move due to the uneven force, and may thus separate from the wastewater tank 01, causing the filter residue to not be collected and directly enter the water storage tank 02, seriously reducing the filtration and purification efficiency of the wastewater.

[0046] In order to solve the above technical problems, a placement groove 0121 is opened on the bottom wall of the second through groove 012, and a limit assembly 5 is provided in the placement groove 0121. The limit assembly 5 includes a fixed rod 51 fixedly connected to the inner wall of the placement groove 0121. The fixed rod 51 is vertically arranged, and a reset spring 52 is sleeved on the outer surface of the fixed rod 51. One end of the reset spring 52 is fixedly connected to the bottom wall of the placement groove 0121, and the other end is connected to the limit block 53. The cross-section of the limit block 53 is trapezoidal. The fixed rod 51 is inserted into the limit block 53 and slides with the limit block 53. When the reset spring 52 is in a natural state, the limit block 53 extends out of the placement groove 0121 and contacts the outer surface of the collection frame 2.

[0047] In the process of pushing the collection frame 2 into the waste water tank 01, under the guidance of the inclined surface of the limit block 53, the collection frame 2 squeezes the limit block 53, and the limit block 53 compresses the return spring 52 and slides along the fixed rod 51 into the placement groove 0121. When the end face of the collection frame 2 hits the inner wall of the waste water tank 01, the pressure on the return spring 52 disappears, and the return spring 52 pushes the limit block 53 to hit the outer surface of the collection frame 2, thereby limiting the collection frame 2 and effectively preventing the collection frame 2 from being affected by undesirable conditions. When uniform force is applied, displacement occurs inside the wastewater tank 01, and the wastewater tank 01 may be separated from the wastewater tank 01; when the collection frame 2 has been collected and needs to be taken out, the worker pulls the collection frame 2 outward, and the worker's pulling force overcomes the elastic force of the reset spring 52, causing the limit block 53 to slide into the placement slot 0121 again. At this time, the collection frame 2 slides out of the wastewater tank 01, and the trapezoidal design of the limit block 53 makes the pushing and pushing process of the collection frame 2 smoother, thereby ensuring the smooth progress of the cleaning of the filter residue and the filtration process.

[0048] The implementation principle of the building wastewater self-treatment recycling system of the embodiment of the present application is as follows: when the filter residue on the filter plate 1 is too much, the worker pushes the collection frame 2 into the wastewater tank 01, and when the end surface of the collection frame 2 touches the pressure sensor 0151, the sensor 0151 receives the pressure signal and transmits it to the second motor 45, the second motor 45 drives the threaded rod 41 to rotate forward, and the threaded rod 41 drives the scraper 43 to move toward the filter plate 1 through the connecting block 42 until the scraper 44 abuts against the surface of the filter plate 1, and then the first motor starts to drive The gear 311 rotates forward, and during the rotation of the gear 311, it moves along the length direction of the rack 0131. The movement of the gear 311 drives the support frame 3 to move, and the support frame 3 drives the filter plate 1 to gradually move toward the first through groove 011. During the sliding process of the filter plate 1, the scraper 44 pushes the filter residue accumulated on the filter plate 1 into the collection frame 2. This arrangement realizes the cleaning of the filter residue on the surface of the filter plate 1, reduces the possibility of excessive filter residue blocking the filter holes, thereby ensuring the smooth progress of subsequent filtering operations and improving the filtration and purification efficiency of wastewater;

[0049] After cleaning is completed, the second motor 45 drives the threaded rod 41 to rotate in the opposite direction, and the threaded rod 41 drives the scraper 43 away from the filter plate 1 until the end of the scraper 44 moves above the opening of the first through groove 011 to prevent the scraper 43 from affecting the resetting process of the filter plate 1. Then the first motor drives the gear 311 to rotate in the opposite direction, and the gear 311 drives the filter plate 1 to move toward the inside of the wastewater tank 01. After the filter plate 1 completely enters the wastewater tank 01, the collection frame 2 is drawn out of the wastewater to above the water storage tank 02 to prevent the collection frame 2 from affecting the subsequent filtration process.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
