Description

Technical Field

[0001] The invention relates to the technical field of underground drainage, and in particular to a device for separating water and gangue from underground ditches. Background Art

[0002] The ditches under coal mines are the main means of underground sewage drainage to ensure the dryness and safety of the mine working environment. In the process of coal mining, due to the complexity of geological conditions and the disturbance of mining activities, a large amount of sewage will be generated, which inevitably carries various solid wastes, especially coal gangue. Coal gangue is a rock-like material with a hard texture and high density. When it flows with water in the underground water, it often gradually gathers together due to mutual collision and sedimentation, and eventually blocks the ditches, seriously affecting the efficiency of the drainage system, and may even cause safety hazards.

[0003] In the past, the cleaning of underground ditches mainly relied on manual operations. Workers used simple tools such as shovels to hoe solid waste such as coal gangue in the ditches onto the road surface, then transferred them from the road surface to the conveyor belt, and finally transported them to the coal warehouse for unified treatment. This traditional cleaning method is not only inefficient and time-consuming, but also greatly increases the labor intensity of employees. Long-term work can easily lead to worker fatigue, affecting work efficiency and operation safety.

[0004] In the field of urban sewage treatment, some relatively advanced technologies and equipment have been developed for the cleaning of solid waste in drainage ditches. For example, the stepped solid-liquid separation equipment uses a rotating staircase structure to transport solid waste step by step upward to a waste bin at a higher height, thereby achieving effective separation of solids and liquids. Another common equipment is an inclined water filter conveyor belt with water filter holes, which can separate sewage from solid waste through the water filter function while conveying solid waste. However, although these devices have solved the problem of cleaning urban sewage drainage ditches to a certain extent, their structures are relatively complex, their volumes are large, and they occupy a large area. They are obviously not suitable for the underground environment of coal mines with limited space. In addition, the water filter conveyor belt is prone to blockage during use, resulting in poor solid-liquid separation, further limiting its application in underground ditch cleaning.

[0005] In summary, the solid-liquid separation equipment used in the existing technology for urban sewage drainage ditches is not suitable for direct application in the separation of water and gangue in underground coal mine ditches due to its large size, large footprint and easy clogging of the water filter conveyor belt. Summary of the invention

[0006] In order to solve the technical problems that the solid-liquid separation equipment used in urban sewage drainage ditches in the prior art has a large structural volume, occupies a large area, is easily blocked resulting in poor solid-liquid separation effect, and is not suitable for underground ditch water gangue separation, the present invention provides an underground ditch water gangue separation device.

[0007] To achieve the above object, the technical solution adopted by the present invention is: A device for separating water gangue for underground ditches comprises a filter residue device, which comprises a support frame which is tilted, a driving wheel is arranged on the top of the support frame, a transmission wheel is arranged on the bottom, a flexible component is connected around the driving wheel and the transmission wheel, a plurality of filter plates are connected to the outer surface of the flexible component, the filter plates are arranged perpendicular to the outer surface of the flexible component, and the plurality of filter plates are evenly arranged along the rotation direction of the flexible component; a separation device is arranged below the top of the support frame, the separation device comprises a frame, a rotating drum is rotatably mounted on the top of the frame, a plurality of separation bins are evenly arranged in the circumferential direction of the rotating drum, the interior of the separation bin is hollow, an opening is opened on the side facing the rotation direction of the rotating drum, and a filtrate hole is opened on the side wall of the separation bin; a ditch cover is provided on the side of the frame away from the filter residue device; the side of the flexible component close to the separation device moves from the driving wheel to the transmission wheel, and the rotating drum and the flexible component have the same rotation direction.

[0008] With the above structural scheme, the driving wheel rotates, driving the flexible component, the transmission wheel and the filter plate to rotate. The gangue in the water flow will be shoveled onto the filter plate. As the filter plate rotates, the gangue is transported to the top of the support frame. During this period, the water driven by the rotation of the filter plate will flow from the filter holes and both sides of the filter plate, leaving only the gangue. When the filter plate rotates over the top of the support frame driven by the flexible component, the gangue will fall from the top of the support frame and fall into the separation bin from the open mouth. Water will flow out from the filtrate hole, and the gangue will remain in the separation bin. As long as the separation bin filled with gangue passes the highest point, the gangue will fall and dump onto the ditch cover. The separation bin will rotate due to the weightlessness and the driving motor that drives the rotating drum to rotate, and the power energy consumed is less. When there is too much gangue, it can be directly pushed to the road surface next to it with a shovel, without having to dig it out of the ditch to the road surface, which is convenient and quick. In addition, the filter residue equipment and the separation equipment are placed in the ditch for use, are small in size, and occupy less space.

[0009] As a preferred implementation of a water-gangue separation device for an underground ditch, the drive wheel and the transmission wheel are sprocket wheels, the flexible component includes a chain and a chain plate, and the chain is meshed with the drive wheel and the transmission wheel.

[0010] By adopting the above structural solution, the chain and chain plate structure are relatively strong and not easy to deform.

[0011] As a preferred implementation of a water-gangue separation device for an underground ditch, the driving wheel and the transmission wheel are roller-shaped structures, and the flexible component is a belt.

[0012] By adopting the above structural solution, the belt structure is simple and the cost is low.

[0013] As a preferred implementation of a water-gangue separation device for an underground ditch, filter holes are provided on the surface of the flexible component and / or the surface of the filter plate.

[0014] The above structural solution facilitates the water driven by the rotation of the filter plate to flow out, leaving only coal gangue on the filter plate.

[0015] As a preferred implementation of a water-gangue separation device for an underground ditch, a folding plate is provided at an edge of the filter plate away from the flexible component. The folding plate is arranged perpendicular to the filter plate and is arranged on one side of the rotation direction of the flexible component.

[0016] By adopting the above structural solution, the folding plate plays a role in preventing coal gangue from falling.

[0017] As a preferred implementation of a water-gangue separation device for an underground ditch, the rotating drum and the supporting frame are eccentrically installed.

[0018] By adopting the above structural solution, the separation bin is easier to rotate.

[0019] As a preferred implementation of a water-gangue separation device for an underground ditch, the side of the separation bin away from the rotating drum is heavier than the side of the separation bin close to the rotating drum.

[0020] By adopting the above structural solution, the separation bin is easier to rotate.

[0021] As a preferred implementation of a water-gangue separation device for an underground ditch, a counterweight is installed on a side of the separation chamber away from the rotating drum.

[0022] By adopting the above structural solution, the separation bin is easier to rotate.

[0023] As a preferred implementation of a water-gangue separation device for an underground ditch, the filtrate hole is opened on a side of the separation chamber away from the rotating drum.

[0024] Adopting the above structural scheme is convenient for water leakage.

[0025] As a preferred implementation of a water-gangue separation device for an underground ditch, a side of the separation bin away from the rotating drum is arc-shaped.

[0026] The above structural scheme is adopted to increase the area and facilitate water leakage.

[0027] The beneficial effects of the present invention include: The driving wheel rotates, driving the flexible component, the transmission wheel and the filter plate to rotate. The gangue in the water flow will be shoveled onto the filter plate. As the filter plate rotates, the gangue is transported to the top of the support frame. During this period, the water driven by the rotation of the filter plate will flow from the filter holes and both sides of the filter plate, leaving only the gangue. When the filter plate rotates over the top of the support frame driven by the flexible component, the gangue will fall from the top of the support frame and fall into the separation bin from the open mouth. Water flows out from the filtrate hole, and the gangue remains in the separation bin. As long as the separation bin filled with gangue passes the highest point, the gangue will fall and dump onto the ditch cover. The separation bin will rotate due to the weightlessness and the driving motor that drives the drum to rotate, consuming less power energy. When there is too much gangue, it can be directly pushed to the road surface next to it with a shovel, without having to dig it out of the ditch to the road surface, which is convenient and quick. In addition, the filter residue equipment and the separation equipment are placed in the ditch for use, are small in size, and occupy less space. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Reference Figure 1-3 , this embodiment proposes a waste separation device for underground ditches, which is placed at the high and low boundary of the underground ditches. The waste separation device for underground ditches includes a filter residue device 1 and a separation device 2, and the filter residue device 1 is located at a higher position than the separation device 2. The ditch can be set up into two sections, one section with a higher terrain and the other section with a lower terrain, and the water flows from the higher section to the lower section. The filter residue device 1 is placed in the ditch with a higher terrain, and the separation device 2 is placed in the ditch with a lower terrain. It is also possible to dig a trench with a lower terrain in the original ditch, and place the separation device 2 in the newly dug trench with a lower terrain, and arrange the filter residue device 1 and the separation device 2 in sequence according to the direction of the water flow. In short, the filter residue device 1 is located at a higher position than the separation device 2.

[0033] The filter residue device 1 includes a support frame 11, the support frame 11 is tilted, the top of the support frame 11 is tilted in the direction of the water flow, a driving wheel 12 is arranged on the top of the support frame 11, the driving wheel 12 can rotate under the drive of a driving motor with waterproof measures, and a transmission wheel 13 is arranged at the bottom, the driving wheel 12 and the transmission wheel 13 are sprockets, and a flexible component 14 is connected around the driving wheel 12 and the transmission wheel 13, referring to Figure 1 , the driving wheel 12 rotates counterclockwise, that is, the side of the flexible component 14 close to the separation device 2 moves from the driving wheel 12 to the transmission wheel 13. The flexible component 14 includes a chain 141 and a chain plate 142, the chain 141 is meshed with the driving wheel 12 and the transmission wheel 13, and the outer surface of the chain plate 142 is connected to a plurality of filter plates 15, the filter plates 15 are arranged perpendicularly to the outer surface of the flexible component 14, and the plurality of filter plates 15 are evenly arranged along the rotation direction of the flexible component 14, and the surfaces of the chain plate 142 and the filter plates 15 are provided with filter holes 16. A folding plate 17 is provided at the edge of the filter plate 15 away from the flexible component 14, and the folding plate 17 is arranged perpendicularly to the filter plate 15, and the folding plate 17 is arranged to one side of the rotation direction of the flexible component 14. When the driving wheel 12 rotates, the chain 141, the chain plate 142, the filter plate 15 and the folding plate 17 are driven to rotate, and the coal gangue in the water flow will be shoveled onto the filter plate 15. The folding plate 17 prevents the coal gangue from falling. As the filter plate 15 and the folding plate 17 rotate, the coal gangue is transported to the top of the support frame 11. During this period, the water driven by the rotation of the filter plate 15 and the folding plate 17 will flow from the filter hole 16 and both sides of the filter plate 15, leaving only the coal gangue. When the filter plate 15 and the folding plate 17 rotate over the top of the support frame 11 driven by the flexible component 14, the coal gangue will fall from the top of the support frame 11.

[0034] Since the height of the coal gangue is relatively high when it falls from the top of the support frame 11, if a ditch cover 3 is set below the coal gangue falling from the support frame 11, so that the coal gangue falls directly onto the ditch cover 3, the coal gangue will roll everywhere and fall back into the ditch. If the ditch cover 3 is raised, the ditch cover 3 needs to be set to a structure with a larger surface area, which occupies a large space and is inconvenient for the staff to clean the coal gangue directly from a place flush with the ground. Therefore, in this embodiment, a separation device 2 is set to receive the coal gangue, and after the coal gangue is concentrated, it is thrown out in a small range and thrown onto the ditch cover 3, which can not only make the coal gangue gather together more regularly, which is convenient for cleaning, but also prevent the coal gangue from rolling back into the ditch.

[0035] The separation device 2 is arranged below the top of the support frame 11. The separation device 2 includes a frame 21. A rotating drum 22 is rotatably mounted on the top of the frame 21. The rotating drum 22 has the same rotation direction as the flexible component 14. Figure 1 In the middle, the drum 22 rotates counterclockwise. The drum 22 is eccentrically mounted to the support frame 11, and a number of separation bins 23 are evenly arranged in the circumferential direction of the drum 22. The separation bins 23 are hollow inside, and an opening is opened on the side facing the rotation direction of the drum 22. The side wall of the separation bins 23 is opened with filtrate holes 231. The side of the separation bin 23 away from the drum 22 is heavier than the side of the separation bin 23 close to the drum 22, and a counterweight is installed on the side of the separation bin 23 away from the drum 22. The coal gangue dropped from the top of the support frame 11 will fall into the separation bin 23 from the opening, and the water will flow out from the filtrate holes 231, and the coal gangue will remain in the separation bin 23. The rotating drum 22 is installed eccentrically, and the weight of the side of the separation bin 23 away from the rotating drum 22 is greater than the weight of the side of the separation bin 23 close to the rotating drum 22. Therefore, as long as the separation bin 23 filled with coal gangue rotates over the highest point and the coal gangue falls, it can automatically rotate downward under the action of gravity, and then rotate again under the action of gravity, inertia and the driving motor that drives the rotating drum 22 to rotate, and the power energy consumed is less.

[0036] A ditch cover 3 is provided on one side of the frame 21 away from the filter residue device 1. Both sides of the ditch cover 3 are placed on the road surface next to the ditch, and the ditch cover 3 covers the ditch. The rotation of the drum 22 drives the separation bin 23 to rotate. When the separation bin 23 rotates to the open side position, the coal gangue is poured from the separation bin 23 onto the ditch cover 3. When there is too much coal gangue, it can be directly pushed to the road surface next to it with a shovel, without having to dig it out from the ditch to the road surface, which is convenient and quick. The side edge of the ditch cover 3 close to the separation device 2 is bent upward to reduce the probability of coal gangue falling back into the ditch from the edge of the ditch cover 3 when there is too much coal gangue accumulation or when the coal gangue is manually cleaned.

[0037] The working principle of this embodiment is: When the driving wheel 12 rotates, the chain 141, the chain plate 142, the filter plate 15 and the folding plate 17 are driven to rotate, and the coal gangue in the water flow will be shoveled onto the filter plate 15. The folding plate 17 plays a role in preventing the coal gangue from falling. With the rotation of the filter plate 15 and the folding plate 17, the coal gangue is transported to the top of the support frame 11. During this period, the water driven by the rotation of the filter plate 15 and the folding plate 17 will flow from the filter hole 16 and the two sides of the filter plate 15, leaving only the coal gangue. When the filter plate 15 and the folding plate 17 rotate over the top of the support frame 11 driven by the flexible component 14, the coal gangue will fall from the top of the support frame 11. The coal gangue falling from the top of the support frame 11 will fall into the separation bin 23 from the open mouth, and the water will flow out from the filtrate hole 231, and the coal gangue will remain in the separation bin 23. The rotating drum 22 is eccentrically installed, and the weight of the side of the separation bin 23 away from the rotating drum 22 is greater than the side of the separation bin 23 close to the rotating drum 22. Therefore, as long as the separation bin 23 filled with coal gangue rotates past the highest point, the coal gangue falls and can automatically rotate downward under the action of gravity, and rotate again under the action of gravity, inertia and the driving motor driving the rotating drum 22 to rotate, and the power energy consumed is relatively small. After the coal gangue falls from the separation bin 23, it is dumped on the ditch cover 3. When the coal gangue is piled up too much, it can be directly pushed to the road surface next to it with a shovel, without having to dig it from the ditch to the road surface, which is convenient and quick.

[0038] In the present embodiment, only three separation bins 23 are illustrated. In fact, the number of separation bins 23 can be more, such as 5, 6, 10, etc. The larger the number, the more coal gangue that can be continuously received from the top of the support frame 11.

[0039] In other embodiments, the driving wheel 12 and the transmission wheel 13 may also be a roller-shaped structure, and the flexible component 14 is a belt. In order to support the filter plate 15, the belt needs to use a harder or thicker rubber belt.

[0040] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
