Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, and in particular to a water supply and drainage device for building construction. Background Technology

[0002] Construction sites, such as tunnel projects, civil engineering, underground engineering, mining sites, concrete mixing plants, sand and gravel yards, and other construction-related processes, generate a large amount of construction wastewater. This wastewater often contains a large amount of pollutants such as mud, sand, gravel, and petroleum. If it is directly discharged into rivers or surface water, it will cause river siltation and water pollution. Moreover, the discharged water cannot be directly recycled, resulting in a waste of water resources.

[0003] A construction water supply and drainage device for building engineering, with the existing patent publication number "CN216922476U", includes a base, a treatment box fixedly installed on the top surface of the base, a filter frame disposed inside the treatment box; a water inlet, the water inlet being opened on the top surface of the treatment box, an installation pipe fixedly installed inside the water inlet; and a disassembly assembly, the disassembly assembly being disposed inside the treatment box for disassembling the filter frame.

[0004] Although the device effectively filters pollutants from wastewater through its filter frames during operation, preventing untreated sewage from being directly discharged into sewers or rivers and reducing environmental pollution, and its design allows users to quickly disassemble and clean the filter frames to prevent clogging and corrosion caused by long-term use, in scenarios requiring large-scale water supply and drainage, such as construction projects, the frequent need to disassemble the filter frames for cleaning, and the necessity to ensure a tight seal at the joints after each disassembly and reinstallation to prevent leaks, makes the maintenance process of the entire filtration system relatively complex and time-consuming. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in existing technologies, in scenarios such as building construction that require a large amount of water supply and drainage, the filter frame needs to be frequently disassembled for cleaning, and the connection must be sealed after each disassembly and reinstallation to prevent water leakage. This makes the maintenance process of the entire filtration system relatively complicated and time-consuming.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a construction water supply and drainage device, including an outer casing, an inlet pipe installed at the top of the outer casing, a drain pipe fixedly installed at the bottom of the outer casing, a filter box slidably connected inside the outer casing, a lifting mechanism connected to the filter box at the upper end of the outer casing, a filter screen fixedly connected to the lower end of the filter box, belt box frames fixedly installed on both sides of the lower end of the filter screen, drive belt reels rotatably connected to both ends of the belt box frames, a transmission belt sleeved between the drive belt reels, a connecting block fixedly connected to the outside of the transmission belt, a push plate fixedly connected between the connecting blocks in the belt box frames at both ends, the lower end of the push plate abutting against the filter screen, an output channel opening at the front end of the filter box, and a corresponding discharge channel opening at the upper end of the outer casing on the side corresponding to the output channel. The movement of the transmission belt in the belt box frame can drive the push plate to move horizontally on the filter screen, pushing the sedimented and filtered garbage and debris, so that the garbage and debris are discharged through the output channel and the discharge channel.

[0007] In a preferred embodiment, a mating bevel gear is fixedly connected to the lower end of the drive belt reel on one side of the belt box frame. A rotating shaft is rotatably connected to the filter box corresponding to the mating bevel gear. A drive bevel gear is fixedly connected to the outer circumference of the rotating shaft.

[0008] In a preferred embodiment, a gear is fixedly connected to the other end of the rotating shaft, and racks are fixedly connected to the inner wall of the outer casing at the locations corresponding to the gears. The racks mesh with the gears for transmission, so that when the filter box is raised or lowered, the gears contact the racks to drive the rotating shaft to rotate.

[0009] In a preferred embodiment, the two ends of the threaded rod rotate in opposite directions. This allows the threaded sleeves at both ends to move closer together when the threaded rod rotates, resulting in more stable movement.

[0010] In a preferred embodiment, the two ends of the threaded rod rotate in opposite directions. This allows the threaded sleeves at both ends to move closer together when the threaded rod rotates, resulting in more stable movement.

[0011] In one preferred embodiment, one end of the threaded rod passes through the outer casing, and a handle is fixedly connected to the passing end. The handle forms a lever that saves effort, making it easy to rotate the threaded rod.

[0012] In a preferred embodiment, a collection hopper is provided at the lower end of the discharge trough. The rear end of the collection hopper is slidably connected to the outer box. By providing the collection hopper, the garbage discharged from the discharge trough can be collected.

A belt 22 is fixedly connected to a connecting block 24 on its outer side. A push plate 18 is fixedly connected between the connecting blocks 24 in the belt box frame 21 at both ends. The lower end of the push plate 18 abuts against the filter screen 17. An output channel 25 is opened at the front end of the filter box 8. A corresponding discharge channel 7 is opened on the upper end of the outer box 1 on the side corresponding to the output channel 25. The push plate 18 can be driven to move horizontally on the filter screen 17 by the movement of the transmission belt 22 in the belt box frame 21, pushing the sedimented and filtered garbage and debris, so that the garbage and debris are discharged through the output channel 25 and the discharge channel 7.

[0027] like Figure 1-6 As shown, a bevel gear 20 is fixedly connected to the lower end of the drive belt reel 23 on one side of the belt box frame 21. A rotating shaft 11 is rotatably connected to the filter box 8 corresponding to the bevel gear 20. A drive bevel gear 19 is fixedly connected to the outer circumference of the rotating shaft 11. The drive bevel gear 19 meshes with the bevel gear 20 for transmission. The rotation of the rotating shaft 11 can drive the drive bevel gear 19 to rotate. The rotation of the drive bevel gear 19 can drive the bevel gear 20 to drive the drive belt reel 23 to rotate, thereby driving the transmission belt 22 to move.

[0028] like Figure 1-6 As shown, a gear 10 is fixedly connected to the other end of the rotating shaft 11, and racks 9 are fixedly connected to the inner wall of the outer box 1 at the locations corresponding to the gear 10. The racks 9 and gears 10 mesh and drive each other, so that when the filter box 8 is raised or lowered, the gears 10 contact the racks 9 and drive the rotating shaft 11 to rotate.

[0029] like Figure 1-6 As shown, the two ends of the threaded rod 12 rotate in opposite directions. This allows the threaded sleeves 15 at both ends to move closer together when the threaded rod 12 rotates, making the movement more stable.

[0030] like Figure 1-6 As shown, the two ends of the threaded rod 12 rotate in opposite directions. This allows the threaded sleeves 15 at both ends to move closer together when the threaded rod 12 rotates, making the movement more stable.

[0031] like Figure 1-6 As shown, one end of the threaded rod 12 passes through the outer casing 1, and a handle 13 is fixedly connected to the through end. The handle 13 forms a lever that saves effort, making it easy to rotate the threaded rod 12.

[0032] like Figure 1-6 As shown, a collection hopper 6 is provided at the lower end of the discharge trough 7. The rear end of the collection hopper 6 is slidably connected to the outer box 1. By setting the collection hopper 6, the garbage discharged from the discharge trough 7 can be collected. The collection hopper 6 is slidable, which makes it easy to pull out the collection hopper 6 to dump the garbage.

[0033] like Figure 1-6 As shown, a trolley 2 is provided at the lower end of the outer box 1, and casters 3 are installed at the four corners of the bottom of the trolley 2. By setting the trolley 2 in conjunction with the casters 3, the mobility of the device is improved, making the device more flexible to use.

[0034] Working principle: After wastewater enters the outer box 1 through the inlet pipe 5, the garbage and impurities in the water are blocked by the filter screen 17. After a period of time, the garbage and impurities on the filter screen 17 need to be cleaned. By rotating the handle 13, the threaded rod 12 is driven to rotate. The rotation of the threaded rod 12 causes the threaded sleeves 15 on both sides to move closer to each other, causing the connecting rod 14 to change angle, thereby driving the filter box 8 to rise. After the filter box 8 is raised, water flows out from the filter screen 17, and the gear 10 rotates after contacting the rack 9, driving the rotating shaft 11 to rotate, thereby driving the drive bevel gear 19 to rotate. The rotation of the drive bevel gear 19 drives the cooperating bevel gear 20 to drive the drive belt disc 23 to rotate, thereby driving the transmission belt 22 to move, driving the push plate 18 to move horizontally on the filter screen 17, pushing the sedimented and filtered garbage and debris, so that the garbage and debris are discharged through the output channel 25 and the discharge channel 7. This application allows for cleaning of impurities on the filter screen without removing it, and the collection hopper 6 can also collect and process impurities centrally, improving wastewater treatment efficiency and making the maintenance process of the filtration system simple and quick.
