Description

Technical Field

[0001] This utility model relates to the field of coal mine geological engineering technology, and more specifically, it relates to a coal mine geological engineering water and slag separation device. Background Technology

[0002] Coal mine geological engineering is an engineering and technical field that studies the geological conditions of coal mines and ensures the safe mining of coal resources. It requires the use of various technical means to solve geological problems in coal mining. Among them, water control is a key link, and water-slag separation is a necessary step in the water control process to achieve wastewater purification and reasonable disposal of waste slag. During coal mining operations, a large amount of slag-containing mine water is generated. If water and slag are not separated in a timely and effective manner, it will not only waste water resources, but also affect the working environment and subsequent processes due to the accumulation of waste slag.

[0003] Existing coal mine geological engineering water control and slag separation devices mostly use simple filter screen structures to achieve water and slag separation. However, in actual use, these devices suffer from the problem of easy clogging of the filter screen. Due to the varying particle sizes and complex composition of impurities in mine slag, waste residue tends to accumulate at the mesh after prolonged filtration, resulting in a significant reduction in water flow efficiency. This necessitates frequent shutdowns to clean the filter screen, which not only affects the continuity of coal mine water control operations and increases manpower maintenance costs, but also accelerates filter screen wear and shortens its service life due to frequent disassembly and assembly. Consequently, these devices cannot efficiently and stably meet the long-term water and slag separation needs of coal mine geological engineering. Utility Model Content

[0009] The present invention is further configured such that a discharge pipe is fixedly connected to the right side of the separation shell, a slurry pump is fixedly connected to the outer surface of the discharge pipe, a stabilizing plate is fixedly connected to the bottom of the right side of the separation shell, and the bottom surface of the slurry pump is fixedly connected to the upper surface of the stabilizing plate.

[0010] The present invention is further configured such that a fixed frame is slidably connected inside the separating shell, the outer surface of the fixed frame is slidably connected to the interior of two inner grooves respectively, a hydraulic cylinder is fixedly connected to the front of the separating shell, wherein the base end of the hydraulic cylinder is fixedly installed on the side surface of the separating shell, the telescopic end is fixedly connected to the inner wall of the fixed frame, one end of the fixed frame extends into the interior of the separating shell, and a first pusher plate and a second pusher plate are fixedly connected to the back of the fixed frame respectively.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The dual-stage separation frame utilizes two inner grooves and its inner walls, along with first and second filter holes, to form a dual-stage filtration structure. After the water-slag mixture enters the frame through the water-slag pipe, it first passes through the first filter hole to filter out larger particles, then through the second filter hole to filter out smaller particles. This, combined with a bottom filter frame for further fine filtration, achieves multi-stage separation of water and slag, avoiding the rapid clogging of a single filter due to varying particle sizes. Simultaneously, the dual-stage discharge frame works in conjunction with a stepped discharge ramp inside the storage tank, allowing the filtered slag to slide down the ramp into the storage tank, reducing slag accumulation within the separation frame. A hydraulic cylinder drives the fixed frame, causing the first and second pusher plates to slide within a stable chute, periodically pushing and cleaning the slag from the inner wall surface of the dual-stage separation frame. A slurry pump then extracts the separated water through a discharge pipe, avoiding frequent manual shutdowns for filter cleaning. This ensures the continuity of water-slag separation operations, reduces labor and maintenance costs, extends equipment lifespan, and efficiently and stably meets the water-slag separation needs of coal mine geological engineering.

[0026] Please see Figures 1-6 The system includes a separation shell 1, a water slag pipe 10 fixedly connected to the left side of the separation shell 1, a double-stage separation frame 16 fixedly connected to the inner wall of the separation shell 1, a separation unit fixedly connected to the separation shell 1 via the double-stage separation frame 16, a double-stage discharge frame 11 fixedly connected to the inner wall of the separation shell 1, and a storage box 9 provided on the back of the separation shell 1.

[0027] Specifically, the water-slag pipe 10 fixedly connected to the left side of the separation shell 1 can introduce the water-slag mixture into the device. The double-stage separation frame 16 fixedly connected to the inner wall of the separation shell 1 provides space for water-slag separation. The separation unit fixedly connected to the double-stage separation frame 16 can realize multi-stage filtration of water-slag. The double-stage discharge frame 11 fixedly connected to the inner wall of the separation shell 1 can guide the movement of the filtered waste residue. The storage box 9 set on the back of the separation shell 1 can collect the waste residue, so that the water-slag mixture can enter the separation device and initially plan the movement path of the waste residue.

[0028] Please see Figures 1-6 The separation unit includes a stepped material discharge sloping seat 12 fixedly connected to the inner wall of the storage tank 9. The front of the double-stage discharge frame 11 is fixedly connected to the back of the double-stage separation frame 16. The inner wall of the double-stage separation frame 16 has two inner grooves 21. The inner bottom wall of the two inner grooves 21 is provided with a plurality of first filter holes 18 and second filter holes 17 respectively. The first filter holes 18 are located above the second filter holes 17 and the filter diameter of the first filter holes 18 is larger than the filter diameter of the second filter holes 17. The water slag pipe 10 is located at one end of the separation shell 1, above the middle of the inner groove 21 on the left side of the double-stage separation frame 16. The bottom surface of the double-stage separation frame 16 is fixedly connected to a filter frame 13.

[0029] Specifically, the stepped discharge ramp 12 fixedly connected to the inner wall of the storage tank 9 allows waste residue to slide down the ramp for easy collection. The front of the dual-stage discharge rack 11 is fixedly connected to the back of the dual-stage separation rack 16, guiding the filtered waste residue in the dual-stage separation rack 16 to the storage tank 9. The two inner grooves 21 opened on the inner wall of the dual-stage separation rack 16 and the first filter hole 18 and the second filter hole 17 on the bottom wall of the rack constitute a dual-stage filtration structure. The filter diameter of the first filter hole 18 is larger than that of the second filter hole 17, allowing larger particles of waste residue to be filtered first and then smaller particles. The water-slag pipe 10 is located at one end of the separation shell 1 above the middle of the inner groove 21 on the left side of the dual-stage separation rack 16, allowing the water-slag mixture to accurately enter the inner groove 21 of the dual-stage separation rack 16. The filter frame 13 fixedly connected to the bottom of the dual-stage separation rack 16 can further finely filter the water, realizing multi-stage separation of water and slag, avoiding rapid clogging of a single filter screen due to different particle sizes, and allowing the waste residue to slide smoothly into the storage tank 9, reducing accumulation in the separation rack.

[0030] Please see Figures 1-6 The right side of the separation shell 1 is fixedly connected to a discharge pipe 4, and the outer surface of the discharge pipe 4 is fixedly connected to a slurry pump 3. The bottom of the right side of the separation shell 1 is fixedly connected to a stabilizing plate 5, and the bottom surface of the slurry pump 3 is fixedly connected to the upper surface of the stabilizing plate 5.

[0031] Specifically, the discharge pipe 4, which is fixedly connected to the right side of the separation shell 1, can discharge the separated water. The slurry pump 3, which is fixedly connected to the outer surface of the discharge pipe 4, can provide power to pump out the water. The stabilizing plate 5, which is fixedly connected to the bottom of the right side of the separation shell 1, can stably support the slurry pump 3 and prevent it from shaking during operation. The three work together to efficiently pump out the separated water, ensure the smooth discharge of water in the device, and maintain the continuous operation of the separation work.

[0032] Please see Figures 1-6 The separation shell 1 is slidably connected to a fixed frame 6. The outer surface of the fixed frame 6 is slidably connected to the interior of two inner grooves 21. A hydraulic cylinder 7 is fixedly connected to the front of the separation shell 1. The base end of the hydraulic cylinder 7 is fixedly installed on the side surface of the separation shell 1, and the telescopic end is fixedly connected to the inner wall of the fixed frame 6. One end of the fixed frame 6 extends into the interior of the separation shell 1. A first pusher plate 15 and a second pusher plate 14 are fixedly connected to the back of the fixed frame 6.

[0033] Specifically, the fixed frame 6, which is slidably connected inside the separation shell 1, can move inside the separation shell 1. Its outer surface is slidably connected to the inside of the two inner grooves 21, and can move within the inner grooves 21 of the double-stage separation frame 16. The telescopic end of the hydraulic cylinder 7, which is fixedly connected to the front of the separation shell 1, is fixedly connected to the inner wall of the fixed frame 6, and can drive the fixed frame 6 to move. When the first pusher plate 15 and the second pusher plate 14, which are fixedly connected to the back of the fixed frame 6, move with the fixed frame 6, they can push and clean the waste residue on the inner wall surface of the double-stage separation frame 16, preventing the waste residue from accumulating and affecting the filtration effect. This realizes the automatic cleaning of the double-stage separation frame 16, avoids frequent manual shutdowns for cleaning, and ensures the continuity of the separation operation.

[0034] Please see Figures 1-6 The inner wall of the dual-stage separation frame 16 is provided with four stabilizing grooves 19. Each stabilizing groove 19 is slidably connected to a stabilizing slide plate 20. The outer surfaces of the first pusher plate 15 and the second pusher plate 14 are fixedly connected to the outer surfaces of the two stabilizing slide plates 20. The front of the separation shell 1 is fixedly connected to a controller 2. The controller 2 is electrically connected to the slurry pump 3 and the hydraulic cylinder 7 respectively through wires. The bottom surface of the separation shell 1 is fixedly connected to four support legs 8.

[0035] Specifically, the four stabilizing grooves 19 on the inner wall of the double-stage separation frame 16 and the internally sliding stabilizing slide plate 20 can limit the movement trajectory of the first pusher plate 15 and the second pusher plate 14, making the movement of the first pusher plate 15 and the second pusher plate 14 more stable. The outer surfaces of the first pusher plate 15 and the second pusher plate 14 are fixedly connected to the outer surfaces of the two stabilizing slide plates 20 to ensure that they move synchronously with the stabilizing slide plates 20. The controller 2 fixedly connected to the front of the separation shell 1 is electrically connected to the slurry pump 3 and the hydraulic cylinder 7 through wires, which can control the operation of the slurry pump 3 and the hydraulic cylinder 7. The four support legs 8 fixedly connected to the bottom of the separation shell 1 can support the device, so that the device is placed stably, ensuring the stable operation of the cleaning mechanism and the normal operation of the entire device, realizing the automated control of the slurry pump 3 and the hydraulic cylinder 7, and improving the stability and working efficiency of the device.

[0036] Working principle:

[0037] The water-slag mixture enters the separation shell 1 through the water-slag pipe 10. The water-slag pipe 10 can control the flow rate of the water-slag through an external connection pipe. It undergoes dual-stage filtration through the first filter hole 18 and the second filter hole 17 of the two inner grooves 21 on the inner wall of the dual-stage separation frame 16. Larger particles of waste slag are intercepted by the first filter hole 18, while smaller particles of waste slag are filtered by the second filter hole 17. The filtered waste slag is guided by the dual-stage discharge frame 11 and slides into the storage tank 9 along the stepped material drop inclined seat 12. The filtered water continues to fall and is further finely filtered by the filter frame 13. The separated water collects in the separation shell 1, and the slurry pump 3 extracts it through the discharge pipe 4. The stabilizing plate 5 provides stable support for the slurry pump 3. When waste slag accumulates on the inner wall surface of the dual-stage separation frame 16... The controller 2 starts the hydraulic cylinder 7, which extends and retracts to drive the fixed frame 6 to slide inside the separation shell 1. The fixed frame 6 drives the first pusher plate 15 and the second pusher plate 14 to move. The first pusher plate 15 and the second pusher plate 14 slide smoothly in the stable slide groove 19 through the stabilizing slide plate 20 to push and clean the waste residue, avoiding the accumulation of waste residue and affecting the filtration effect, and ensuring that the separation operation is carried out continuously and efficiently. Since the cross-section of the double-stage separation frame 16 is much larger than that of the water-slag pipe 10, plus the limitation of the inner tank 21, and the first pusher plate 15 and the second pusher plate 14 driven by the hydraulic cylinder 7 to clean the coal slag accumulated inside the double-stage separation frame 16 in time, the water-slag mixture will not enter the storage tank 9, and the water-slag can be continuously separated.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
