Description

Technical Field

[0001] This application relates to the field of environmental engineering technology, and more specifically, to a sludge sedimentation and separation device for mine water treatment. Background Technology

[0002] Mine water is a mixed body of groundwater, surface water and other water sources that is generated during the mining of mineral resources. It is an inevitable byproduct of mining. Its formation, properties and treatment are closely related to mining technology and geological conditions, and it also has an important impact on the mine's ecological environment and safe production.

[0003] In the process of mine water sludge treatment, sedimentation separation is the core pretreatment step, which is essentially to achieve solid-liquid separation by using physical gravity. Inclined tube sedimentation tanks are key equipment that significantly improve sedimentation separation efficiency through optimized structural design.

[0004] However, most existing sedimentation tanks adopt a planar structure design at the bottom and do not have a dedicated sludge collection component. After the muddy water has settled in the tank, the sludge will be randomly dispersed and deposited in various places on the bottom plane of the tank. Affected by water flow disturbance, some sludge will also form irregularly distributed mud piles or mud bands on the bottom of the tank. This dispersed deposition state makes it difficult for staff to accurately locate the sludge accumulation area, resulting in a significant extension of the cleaning time.

[0005] In view of this, we propose a sludge sedimentation and separation device for mine water treatment. Utility Model Content

The sludge collection box is shaped to match the placement trough. Two pull ropes are fixed to the top of the support plate. The pull ropes are wound and rolled up under external force.

A rotating wheel is rotatably connected inside the fixing parts. The rotating wheel is recessed inside the sedimentation tank. An inner groove is opened on the outer wall of the rotating wheel to limit the position of the pull rope. A limit frame is fixed to the top of the fixing parts.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5 This application discloses a sludge sedimentation and separation device for mine water treatment, referring to... Figures 1-5This application discloses a sludge sedimentation and separation device for mine water treatment, comprising a sedimentation tank 1, a sludge cleaning mechanism 2, and a guide rope mechanism 3. The sedimentation tank 1 has two placement slots 11 inside, and a guide plate 12 with an arc structure is fixed to the inner wall of the sedimentation tank 1. The guide plate 12 is located inside the sedimentation tank 1 and is used to clean the sludge settled in the sedimentation tank 1. The guide rope mechanism 2 is located at the top of the sedimentation tank 1. The sludge cleaning mechanism 2 includes a sliding support plate 21, which slides up and down along the inner wall of the sedimentation tank 1 under external force. A sludge collection box 22 is provided on the outer wall of the support plate 21 for collecting the settled sludge. One side of the sludge collection box 22 has an inclined structure, and the sludge collection box 22 is shaped to match the placement slots 11. Two guide rope mechanisms 3 are fixed to the top of the support plate 21. Rope 23 is wound and wound by an external force; rope guide mechanism 3 is used to limit the position of rope 23; the sludge cleaning mechanism 2 also includes a counterweight block 24 fixed to the inner wall of the sludge cleaning mechanism 2; two fixed seats 25 are fixed to the outside of the sedimentation tank 1; a servo motor 26 is installed on the outer wall of the fixed seat 25; a rotating rod 27 is fixed to the output shaft of the servo motor 26; a support frame 28 is rotatably connected to the end of the rotating rod 27; the support frame 28 is fixedly connected to the outer wall of the sedimentation tank 1; a receiving cylinder 29 is fixed to both ends of the rotating rod 27; the receiving cylinder 29 is fixedly connected to the rope 23 and is used to wind the rope 23; an inlet pipe 15 is installed at one end of the sedimentation tank 1; an inclined plate tank 16 is fixed to the other end of the sedimentation tank 1; an outlet pipe 17 is installed at the end of the inclined plate tank 16.

[0029] The sedimentation tank 1 and inclined plate tank 16 need to be assembled and installed in the designated working area. Then, the inlet pipe 15 can be connected to the external raw liquid pipeline and continuously injected into the sedimentation tank 1. The sludge in the raw liquid will settle inside the sedimentation tank 1 under gravity. After multiple sedimentation cycles, the clear water can be discharged from the outlet pipe 17. Simultaneously, the settled sludge, after reaching the bottom, will contact the arc-shaped guide plate 12 and slide along the outer wall of the guide plate 12 into the sludge collection box 22 for collection. When cleaning the bottom of the sedimentation tank 1 closest to the inlet pipe 15 is required, the operator can activate the two servo motors 26 to rotate the rotating rod 27, which will wind the pull rope 23 into the collection cylinder 29 for collection. At the same time, the... Plate 21 can slide on the inner wall of sedimentation tank 1 and pull the sludge collection box 22 out from the placement groove 11 until the sludge collection box 22 is moved to the highest position, so that the sludge can be cleaned up. After the sludge is cleaned up, the rotating rod 27 can be driven to rotate in the opposite direction. Under the action of the weight of the counterweight 24, the sludge collection box 22 is reset. The guide rope mechanism 3 can limit the operation of the pull rope 23. This step, under the action of the sludge collection box 22, can collect the sludge at the bottom of sedimentation tank 1. When the bottom of sedimentation tank 1 is flat, the position of the sludge that sinks is difficult to control, which makes it more troublesome for the staff to clean. At the same time, frequent cleaning of sludge can avoid the phenomenon of sludge accumulating and hardening for a long time.

[0030] Reference Figures 1-5 The guide rope mechanism 3 includes multiple fixing parts 31 fixed to the top of the sedimentation tank 1. A rotating wheel 32 is rotatably connected inside each fixing part 31. The rotating wheel 32 is recessed inside the sedimentation tank 1, and its outer wall has an inner groove 33 for limiting the position of the pull rope 23. A limiting frame 34 is fixedly connected to the top of the fixing parts 31, and two shielding pads 35 are fixedly connected to the outer wall of the limiting frame 34 for protecting the inner groove 33. When the position of the pull rope 23 needs to be limited, the movable pull rope 23 can be locked inside the inner groove 33. 3. Under the action of rotational resistance, the wheel 32 can rotate. The unfolded limiting frame 34 can limit the top position of the pull rope 23. At the same time, the shielding pad 35 can shield the sludge splashed from the outside. This step, together with the rotating fixing part 31, can reduce the phenomenon of the pull rope 23 deviating during use and reduce the wear caused by direct contact with the top of the sedimentation tank 1. The shielding pad 35 can reduce the problem of sludge splashing and transferring to the inner tank 33, which leads to greater resistance when contacting the pull rope 23.

[0031] Reference Figures 1-5 The placement trough 11 has a storage trough 13 on its inclined surface. A support rod 4 is fixed to the inner wall of the storage trough 13. A rotating plate 41 is rotatably connected to the middle of the support rod 4. A float 42 is fixed to the end of the rotating plate 41. A slot 43 is provided on one side of both the rotating plate 41 and the slot 43, and the slot 43 is set upwards. The end of the float 42 has an arc structure. Because the storage trough 13 is provided in the placement trough 11, when the mud collection box 22 is detached from the placement trough 11, the buoyancy of the float 42 can lift the rotating plate 41, forming an inclined angle with the guide plate 12, and blocking part of the silt. The mud collection box 22 is then... When moving downwards, the weight of the pull rope 23 and the limiting bracket 34 can press the rotating plate 41 back into the storage slot 13 for storage. As the rotating plate 41 tilts and changes direction, some of the accumulated impurities can be transferred into the interstitial slot 43. This step, combined with the tilted rotating plate 41, can reduce the problem of some silt entering the placement slot 11 due to lack of obstruction after the mud collection box 22 is lifted, thus affecting the subsequent closing of the mud collection box 22. This improves the stability of subsequent silt collection. The rounded structure at the end of the float 42 can reduce the phenomenon of jamming when the bottom of the mud collection box 22 is pressed to close the rotating plate 41.

[0032] Reference Figures 1-5A rotating shaft 221 is fixedly connected to one side of the sludge collection box 22, which is located near the support plate 21. The sludge collection box 22 is rotatably connected to the support plate 21 via the rotating shaft 221. A baffle plate 14 is fixedly connected to the outer wall of the sedimentation tank 1, and the outer wall of the baffle plate 14 has an inclined structure. When the sludge collection box 22 is raised to its highest position, the operator can directly flip the sludge collection box 22 and pour out the sludge inside. The poured-out sludge can directly contact the baffle plate 14 and slide out. This step, combined with the rotating sludge collection box 22, can improve the speed of sludge cleaning. With the baffle plate 14, it can reduce the sludge residue on the outer wall of the rotating rod 27 after being poured in, thus avoiding problems that may affect subsequent use.

[0033] In summary, the mine water treatment sludge sedimentation and separation device disclosed in this application requires the sedimentation tank 1 and the inclined plate tank 16 to be assembled and installed in the designated working area. Then, the inlet pipe 15 can be connected to the external raw liquid pipeline and continuously injected into the sedimentation tank 1. The sludge in the raw liquid will settle inside the sedimentation tank 1 under the action of gravity. After multiple sedimentation cycles, the clean water can be discharged from the outlet pipe 17. Simultaneously, the settled sludge, after reaching the bottom, will contact the arc-shaped guide plate 12 and slide along the outer wall of the guide plate 12 into the sludge collection box 22 for collection. When cleaning is required at the bottom of the sedimentation tank 1 closest to the inlet pipe 15, the operator can activate the two servo motors 26 to rotate the rotating rod 27, which will wind the pull rope 23 into the collection cylinder 29. At the same time, the pallet 21 will slide against the inner wall of the sedimentation tank 1, pulling the sludge collection box 22 out of the placement trough 11. Once the sludge collection box 22 is moved to its highest position, the sludge can be completely cleaned. After the sludge is cleaned, the rotating rod 27 can be driven in the opposite direction to rotate, and under the influence of the weight of the counterweight 24, the sludge collection can be completed. The box 22 is reset, and the guide rope mechanism 3 can limit the operation of the pull rope 23. When the position of the pull rope 23 needs to be limited, the movable pull rope 23 can be locked in the inner groove 33. At the same time, under the action of the rotational resistance of the pull rope 23, the rotating wheel 32 can be rotated. The unfolded limiting frame 34 can limit the position of the top of the pull rope 23. Meanwhile, the shielding pad 35 can block the mud splashed from the outside. By opening the storage groove 13 in the placement groove 11, when the mud collection box 22 is detached from the placement groove 11, under the action of the buoyancy of the float 42, the rotating wheel 32 can be stopped. The plate 41 is raised and forms an inclined angle with the guide plate 12, blocking some of the silt. When the mud collection box 22 moves downward, the weight of the pull rope 23 and the limit frame 34 can press the rotating plate 41 into the storage groove 13 for storage. At the same time as the rotating plate 41 tilts and changes, some of the impurities that have been blocked can be transferred into the interstitial groove 43. When the mud collection box 22 is raised to its highest position, the staff can directly flip the mud collection box 22 and pour out the silt inside. The poured-out silt can directly contact the shield plate 14 and slide out.
