Description

Technical Field

[0001] This utility model relates to the field of mine water cleaning and pollution control, and in particular to a coal mine water cleaning and pollution diversion and collection device. Background Technology

[0002] During coal mining, a large amount of mine water is generated. Mine water typically contains a large amount of suspended solids such as coal dust, rock cuttings, and silt. In order to realize the resource utilization of mine water (such as reuse for underground dust control, surface irrigation, etc.) or to meet discharge standards, it is usually necessary to carry out clean and dirty water separation treatment, that is, to separate impurities and collect relatively clean water.

[0003] In existing technologies, filtration devices are one of the key pieces of equipment for separating clean and contaminated water. For example, Chinese utility model patent CN222804843U discloses a coal mine water clean and contaminated water separation and collection device. This device intercepts impurities by setting up a filter screen and uses a linkage mechanism such as a tray, connecting rod, and pull plate to collect and store the intercepted impurities in a specific area. When the impurities accumulate to a certain level, the stored impurities can be removed from the filter screen area by lifting the pull plate, thereby preventing the device from becoming completely blocked due to impurity accumulation to a certain extent.

[0004] However, this existing technology has a significant drawback: the cleaning process of impurities requires manual operation of the plate, and the equipment must be stopped during the cleaning process (i.e., the inflow and treatment of mine water must be stopped). Since coal mine production is continuous, mine water generation is also continuous. Frequent shutdowns for cleaning operations will significantly interrupt the entire water treatment process, resulting in a shortened effective treatment time and a decrease in the amount of water treated per unit time. This will fail to meet the needs of continuous drainage and high-flow treatment in coal mines, thus affecting the overall efficiency of wastewater treatment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a coal mine water separation and collection device to solve the technical problems in the prior art.

[0006] To achieve the above objectives, this utility model provides a coal mine water separation and collection device, including a collection box and a filter plate fixed inside the collection box for isolating impurities. The upper side wall of the collection box is provided with a water inlet. The device further includes: A fixed cylinder is vertically fixed to the top wall of the collection box and has an opening at the bottom. A spiral conveying rod is rotatably installed inside the cylinder. The bottom of the spiral conveying rod is rotatably connected to the bottom of the collection box through a bearing, and the top extension end penetrates through the top wall of the collection box. The motor is fixed to the bottom of the collection box and its output shaft is connected to the bottom of the screw conveyor rod; The sewage discharge end connects to the upper end of the fixed cylinder and extends outward through the side wall of the collection box; The device also includes a cleaning mechanism, which comprises: The cleaning brush is attached parallel to the upper surface of the filter plate. A pair of guide sleeves are symmetrically slidably installed at both ends of the cleaning brush and fixed to the inner wall of the collection box; At least one chute is provided on the top of the collection box, within which a sliding plate is installed. The guide rod passes vertically through the through hole of the slide plate and is fixed at the bottom to the cleaning brush; The movable component includes a connecting rod fixed to the slide plate and a waist-shaped sliding sleeve disposed at the end of the connecting rod; A positioning pin is slidably inserted into a waist-shaped sliding sleeve, and a rotating disk is fixed at its bottom end. The rotating disk is fixedly connected to the extension end of the spiral conveyor rod.

[0007] Preferably, the spiral blades of the spiral conveyor rod are provided with a plurality of water outlet holes at equal intervals along the circumference.

[0008] Preferably, the filter plate is inclinedly arranged inside the collection box, with its upper end fixed to the inner wall of the collection box and its lower end connected to a guide plate, which is fixed to the bottom wall of the collection box. The guide plate is located directly below the fixed cylinder and has a central opening, with the central axis of the opening coinciding with the central axis of the screw conveyor.

[0009] Preferably, the guide plate has inclined surfaces on its side near the filter plate and at its front and rear ends, and the inclined surfaces extend downwards from the edge toward the center of the opening.

[0010] Preferably, there are two chutes, symmetrically distributed on both sides of the top of the collection box.

[0011] Preferably, the inner diameter of the waist-shaped sliding sleeve is larger than the diameter of the rotating disk.

[0012] Preferably, the inner wall of the through hole of the slide plate is embedded with a plurality of balls, and the balls roll in contact with the side wall of the guide rod.

[0013] The beneficial effects of this utility model are as follows: The coal mine water clean and dirty water diversion and collection device of this utility model, through the setting of components such as spiral conveyor rod, water outlet and filter plate, after the water flow washes the coal slag, gravel and other impurities filtered from the sewage down to the position of the spiral conveyor rod above the guide plate, the spiral conveyor rod transports the coal slag, gravel and other impurities to the upper end of the fixed cylinder and automatically discharges them from the sewage discharge end, realizing the automatic cleaning of coal slag, gravel and other impurities, avoiding the need for manual operation or machine shutdown for cleaning, which affects the overall sewage treatment efficiency; By incorporating components such as a spiral conveyor, cleaning brushes, and a rotating disc, the cleaning brushes reciprocate to clean the impurities on the filter plate surface as the spiral conveyor rotates and transports impurities. This reduces the clogging of the filter plate pores and pushes the impurities into the guide plate for collection, further improving the overall wastewater treatment efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] The first aspect of this utility model proposes a coal mine water separation and collection device, such as... Figure 1-5 As shown, the device includes a collection box 1 and a filter plate 2 fixed inside the collection box 1 for isolating impurities. The upper side wall of the collection box 1 has a water inlet 101. The device also includes: The fixed cylinder 3 is vertically fixed to the top wall of the collection box 1 and has an opening at the bottom. A spiral conveying rod 4 is rotatably installed inside it. The bottom of the spiral conveying rod 4 is rotatably connected to the bottom of the collection box 1 through a bearing, and the top extension end penetrates the top wall of the collection box 1. Motor 5 is fixed to the bottom of collection box 1 and its output shaft is connected to the bottom of screw conveyor 4. It should be added that there is a flange connecting the output end of motor 5 and the outer side of the bottom of collection box 1 to a sealed cavity, which is equipped with a mechanical seal. The stationary ring is fixed on the sealed cavity, and the rotating ring is fixed on the rotating shaft through a bushing or directly to improve the sealing effect at the bottom of collection box 1. The sewage discharge end 6 connects to the upper end of the fixed cylinder 3 and extends outward through the side wall of the collection box 1; The device also includes a cleaning mechanism, which comprises: Cleaning brush 9 is attached parallel to the upper surface of filter plate 2; A pair of guide sleeves 10 are symmetrically slidably installed at both ends of the cleaning brush 9 and fixed to the inner wall of the collection box 1; it should be added that guide pins are fixed at both ends of the cleaning brush 9, and the guide pins are slidably installed in the guide groove on one side of the guide sleeve 10. At least one chute 102 is provided on the top of the collection box 1, and a sliding plate 12 is slidably installed therein; The guide rod 11 vertically passes through the through hole of the slide plate 12 and its bottom end is fixed to the cleaning brush 9; The movable component 13 includes a connecting rod fixed to the slide plate 12 and a waist-shaped sliding sleeve disposed at the end of the connecting rod; Positioning pin 14 is slidably inserted into waist-shaped sliding sleeve, and its bottom end is fixed to rotating disk 15; The rotating disk 15 is fixedly connected to the extension end of the screw conveyor rod 4.

[0020] As the spiral conveyor 4 rotates, the top of the spiral conveyor 4 rotates via the rotating disk 15 fixed at the extended end. This causes the positioning pin 14 fixed on one side of the rotating disk 15 to move the waist-shaped sliding sleeve at one end of the moving part 13. Since the other end of the moving part 13 is fixed to the slide plate 12 via the connecting rod, the moving part 13 makes a reciprocating linear motion as the rotating disk 15 rotates. This causes the positioning pin 14 to move one end of the moving part 13, and the moving part 13 pulls the slide plate 12 to move back and forth on the slide groove 102. At the same time, the guide rod 11 on the slide plate 12 drives the cleaning brush 9 fixed at the bottom to move on the inner wall of the guide sleeve 10. When the cleaning brush 9 moves to the lower part of the guide sleeve 10, the guide rod 11 moves downward on the slide plate 12 to guide the movement of the cleaning brush 9. This allows the cleaning brush 9 to clean and sweep the impurities on the surface of the filter plate 2, reducing the clogging of the filter holes in the filter plate 2, and pushing the impurities into the guide plate 8 for collection.

[0021] In this embodiment, the spiral blades of the spiral conveyor 4 have several outlet holes 7 evenly spaced along the circumference. As the motor 5 drives the spiral conveyor 4 to rotate, it transports impurities such as slag and gravel filtered by the filter plate 2 to the upper end of the fixed cylinder 3. During this transport, wastewater flows back to the inside of the collection box 1 through the outlet holes 7, while the slag, gravel, and other impurities are automatically discharged from the drain end 6 via the conveying action of the spiral conveyor 4. This achieves automatic cleaning of the slag, gravel, and other impurities, avoiding the need for manual operation or machine shutdown for cleaning, which would affect the overall wastewater treatment efficiency. It should be noted that the drain end 6 can be a rectangular or cylindrical structure, as long as it allows for the discharge of impurities.

[0022] In this embodiment: the filter plate 2 is inclinedly arranged inside the collection box 1, its upper end is fixed to the inner wall of the collection box 1, and its lower end is connected to the guide plate 8, which is fixed to the bottom wall of the collection box 1; because the filter plate 2 is inclined, when impurities in the sewage are filtered, the filtered water flows through the filter holes to the drain end at the lower end of the collection box 1, and the impurities will fall from the inclined surface of the filter plate 2 into the guide plate 8 for collection along with the water flow. The guide plate 8 is located directly below the fixed cylinder 3 and has a central opening, with the central axis of the opening coinciding with the central axis of the screw conveyor 4. It should be noted that this opening design ensures that the output end of the motor 5 drives the screw conveyor 4 without interference during rotation.

[0023] In this embodiment, the guide plate 8 has inclined surfaces on its side near the filter plate 2 and at both its front and rear ends, and the inclined surfaces extend downwards from the edge towards the center of the opening. After impurities such as slag and gravel fall into the guide plate 8, since the inclined surfaces of the inner wall of the guide plate 8 are all inclined towards the opening, the impurities can be concentrated and fall below the screw conveyor 4. As the screw conveyor 4 rotates, it can effectively transport the impurities and discharge the slag, gravel and other impurities.

[0024] In this embodiment, there are two chute 102s, symmetrically distributed on both sides of the top of the collection box 1. The two chute 102s allow the two guide rods 11 to move symmetrically through the slide plate 12, thereby further improving the stability of the cleaning brush 9's movement.

[0025] In this embodiment, the inner diameter of the waist-shaped sliding sleeve is larger than the diameter of the rotating disk 15. As the rotating disk 15 drives the positioning pin 14 to rotate, the moving part 13 is pulled by the sliding plate 12, so that the positioning pin 14 can only move back and forth in the waist-shaped sliding sleeve. This allows the positioning pin 14 to pull the sliding plate 12 fixed at the end of the moving part 13 to move back and forth. Furthermore, since the inner diameter of the waist-shaped sliding sleeve is larger than the diameter of the rotating disk 15, interference problems are avoided during the reciprocating movement of the positioning pin 14.

[0026] In this embodiment, a plurality of balls are embedded in the inner wall of the through hole of the slide plate 12, and the balls roll in contact with the side wall of the guide rod 11. By setting the balls, the contact area between the inner wall of the through hole and the guide rod 11 can be reduced, the friction between the two can be reduced, and thus the smoothness of the guide rod 11 when moving up and down can be improved.

[0027] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
