Description

Technical Field

[0001] The utility model relates to the technical field of biological fillers, in particular to a lifting biological filler device. Background Art

[0002] Biological fillers are materials used for sewage treatment. Their function is to increase the biomass and biological activity in the wastewater treatment system, thereby accelerating the decomposition and treatment of chemical substances in the wastewater. Biological fillers are usually made of materials such as plastics or ceramics, and their surfaces have a large number of tiny holes, which are conducive to the attachment and growth of bacteria, thus providing sufficient biomass and growth space for wastewater treatment. The service life of biological fillers depends on the type of filler, the quality of the treated water, and the water flow rate. Biological fillers are supported and suspended by multiple frames and are located above the aeration discs installed at the bottom of the pool. When it is necessary to replace the biological fillers or maintain the aeration discs, they need to be lifted.

[0003] After retrieval, the patent document with the publication number: CN214571002U discloses a lifting biological filler device, which directly hoists the first aerobic biological filler module and the second aerobic biological filler module into the reaction area in the pool body by installing a lifting mechanism on the pool wall of the pool body. This structure can regularly lift the blocks during operation to clean and inspect the bottom aeration discs and replace the faulty aeration mechanism, and the maintenance process does not affect the normal operation of the system.

[0004] When maintaining some fillers or local aeration mechanisms of the above device, it is necessary to take out the first aerobic biological filler module and the second aerobic biological filler module as a whole. When the pool body is large and more filler frames and biological fillers need to be installed, the way of taking out as a whole cannot perform individual maintenance according to requirements, which undoubtedly increases the maintenance cost. Moreover, after the frame in the central position is lifted, the staff cannot reach the frame and the biological fillers, so maintenance cannot be carried out either. Therefore, we propose a lifting biological filler device to solve the above problems. Summary of the Utility Model

[0009] Preferably, a circular hole is opened on the outer wall of the device frame. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the first motor. By setting the first motor to drive the bidirectional screw rod to rotate, the positions of the two rectangular blocks are adjusted, which is convenient for the hooks to suspend and lift frames with different widths, increasing applicability.

[0010] Preferably, two sliding holes are opened on the outer wall of the device frame. The inner walls of the two sliding holes are respectively slidably connected to the outer walls of the two steel wire ropes. The sliding holes assist the steel wire ropes to move.

A lock is provided between the opening and closing door 3 and the guardrail 2, and a staff member can stand on the vehicle-mounted platform 1.

[0023] Four track wheels 4 are rotatably connected to the outer wall of the vehicle-mounted station 1. The four track wheels 4 are rotated by an existing driving device (DC motor) and a transmission device (gearbox and shaft body), and are powered by a battery, usually a DC battery. The battery pack provides the required electrical energy, and the battery pack is located inside the vehicle-mounted station 1. The four track wheels 4 are slidably connected to two guide rails 5 in pairs, and the four track wheels 4 are supported by the guide rails 5, while the guide rails 5 are supported by the pool body and an existing steel structure.

[0024] A device frame 6 is fixedly connected to the bottom of the vehicle-mounted station 1. A winding roller 8 is rotatably connected inside the device frame 6. Both ends of the winding roller 8 are fixedly sleeved with bearings, and the outer rings of the bearings are fixedly connected to the inner wall of the device frame 6.

[0025] A machine frame is fixedly connected to the outer wall of the device frame 6. A first motor 7 is fixedly connected inside the machine frame. The machine frame protects the first motor 7. A circular hole is opened on the outer wall of the device frame 6, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the first motor 7. The outer wall of the output shaft of the first motor 7 is fixedly connected to the outer wall of the winding roller 8.

[0026] Two steel wire ropes 9 are fixedly connected to the outer wall of the winding roller 8. The operation of the first motor 7 drives the winding roller 8 to rotate, and the rotation of the winding roller 8 winds and unwinds the steel wire ropes 9. Two sliding holes are opened on the outer wall of the device frame 6, and the inner walls of the two sliding holes are respectively slidably connected to the outer walls of the two steel wire ropes 9. The bottoms of the two steel wire ropes 9 are fixedly connected to the same bottom frame 10. After the steel wire ropes 9 are unwound, the bottom frame 10 moves downward by its own weight, and the bottom frame 10 is lifted when being wound.

[0027] A suspension mechanism is provided on the outer wall of the bottom frame 10. The suspension mechanism includes two hooks 14. A strip-shaped groove is opened on the outer wall of the bottom frame 10, and the inner wall of the strip-shaped groove is slidably connected to the outer wall of the hook 14. A second motor 11 is fixedly connected inside the bottom frame 10. A bidirectional screw 12 is fixedly connected to the outer wall of the output shaft of the second motor 11. Bearings are fixedly sleeved on the outer wall of the bidirectional screw 12, and the outer rings of the bearings are fixedly connected to the inner wall of the bottom frame 10.

[0028] Two rectangular blocks 13 are threadedly sleeved on the outer wall of the bidirectional screw 12. The operation of the second motor 11 drives the bidirectional screw 12 to rotate, so that the two rectangular blocks 13 move relatively. The bottoms of the two rectangular blocks 13 are respectively fixedly connected to the tops of the two hooks 14. A partition 15 is sleeved on the outer wall of the output shaft of the second motor 11, and the outer wall of the partition 15 is fixedly connected to the inner wall of the bottom frame 10. The partition 15 plays a sealing role. At the same time, both the first motor 7 and the second motor 11 have waterproof structural parts and are coated with waterproof paint.

[0029] Working principle: Both ends of the two guide rails 5 are installed on the top of the existing pool body, and the vehicle-mounted platform 1 is located on the two guide rails 5 through four track wheels 4. When the vehicle-mounted platform 1 moves, power is transmitted to the four track wheels 4 through the existing driving device and transmission device, and the vehicle-mounted platform 1 is driven to move by the track wheels 4, so that it can move above the pool body, which is convenient for lifting the frames and biological fillers at different positions; during lifting, the first motor 7 operates to drive the winding roller 8 to rotate, and the winding roller 8 rotates to unwind the steel wire rope 9. After the steel wire rope 9 is unwound, the bottom frame 10 moves downward due to its own weight. The second motor 11 operates to drive the bidirectional screw 12 to rotate, so that the two rectangular blocks 13 move relatively, changing the relative positions of the two hooks 14, which is convenient for hanging frames of different widths. The frame is located in the pool. After the hook 14 is located inside the frame, the second motor 11 operates again, so that the rectangular block 13 drives the hook 14 to move outward, so that the hook 14 hooks the outer walls on both sides of the frame. Subsequently, the first motor 7 operates to wind up the steel wire rope 9, driving the bottom frame 10, the frame and the biological filler to be lifted. And the user can stand on the vehicle-mounted platform 1 and be protected by the guardrail 2. After the biological filler is lifted, the biological filler on the frame can be fished or hooked up by the existing telescopic fishing rod, or the vehicle-mounted platform 1 can be driven to the edge of the pool to maintain the biological filler.
