Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine drainage technology, specifically a mine drainage device that is easy to clean. Background Technology
[0002] During mining operations, large amounts of groundwater, precipitation, and production water flow into the mine, creating water inrushes. These inrushes can be several times, or even tens of times, the amount of water extracted. If not drained promptly and effectively, they can easily cause mine flooding, threatening operational safety and hindering mining efficiency. Therefore, the reliability of mine drainage equipment is a critical infrastructure element for ensuring safe mine production.
[0003] In existing technologies, mine drainage systems typically use pumps in conjunction with pipelines for drainage operations, and install filters at the pipeline inlet to intercept large particles of impurities such as ore debris and silt, preventing blockages in the pumps or pipelines. While this solution can initially address the problem of impurity intrusion, it has significant drawbacks in practical applications:
[0004] 1. When the filter screen is exposed to mine water with high impurity content for a long time, its pores are easily blocked by fine particles and sticky substances, which leads to increased water flow resistance, reduced drainage flow, and in severe cases, complete interruption of drainage.
[0005] 2. Traditional filters are mostly fixed in narrow spaces inside pipes. Cleaning operations require frequent disassembly of pipe components, which not only consumes a lot of manpower, but also poses safety risks when carrying out maintenance in complex underground environments.
[0006] 3. Fine impurities that fall off during the flushing process are prone to deposit at pipe bends, forming localized caking and further increasing maintenance pressure. Utility Model Content
[0007] The main purpose of this utility model is to provide a mine drainage device with self-cleaning ability that is easy to clean.
[0008] This utility model provides a mine drainage device that is easy to clean, including a base plate and a water pump, a water tank, a liquid supply pump, and a motor mounted on it. The water pump's inlet end is connected to a rotatable filter mechanism via an inlet pipe, and its outlet end is connected to a drainage pipe. The filter mechanism includes a first housing and a second housing that are coaxially connected. The first housing contains a filter assembly that can rotate around an axis. The motor is connected to the filter assembly via a gear transmission mechanism. The side wall of the second housing has a flushing assembly that communicates with the liquid supply pump, and the spray direction of the flushing assembly is towards the surface of the filter assembly. A guide structure to prevent impurity accumulation is provided downstream of the filter assembly.
[0009] In one embodiment of the above-mentioned device, a bottom wheel is provided at the bottom of the base plate, and the bottom wheel is a swivel wheel.
[0010] In one embodiment of the above-mentioned equipment, the water pump has a drain pipe at its outlet end and an inlet pipe at its inlet end. The inlet pipe has a transfer pipe at its inlet end, and the transfer pipe is fixed above the base plate by a support rod. One end of the transfer pipe has a first housing, and one end of the inlet pipe has a second housing.
[0011] In one embodiment of the above-mentioned device, the first housing and the second housing are fixed and kept in communication by peripheral mating flanges and bolts.
[0012] In one embodiment of the above-mentioned device, the filter assembly includes an annular frame and a filter plate fixedly disposed inside the annular frame. Annular blocks are respectively installed on both sides of the annular frame. An annular groove for the annular blocks to mate is provided at the contact position between the first housing and the annular frame. The annular blocks are embedded in the annular groove to achieve a rotatable connection.
[0013] In one embodiment of the above-mentioned device, the outer ring of the ring frame is provided with a toothed ring, and the output end of the motor is provided with a gear that meshes with the toothed ring; the motor is a servo motor.
[0014] In one embodiment of the above-mentioned device, the flow guiding structure is a conical sleeve, which is located inside the first housing and fixed to the side of the filter assembly away from the rinsing assembly.
[0015] In one embodiment of the above-mentioned device, the rinsing assembly includes a fixed pipe provided on the outer wall of the second housing, and a water spray pipe inserted into the interior of the second housing and located on one side of the filter plate at the water outlet end of the fixed pipe, and the water spray pipe is provided with multiple water outlet holes.
[0016] In one embodiment of the above-mentioned device, the inlet end of the liquid supply pump is connected to the water tank, and the outlet end of the liquid supply pump is connected to the fixed pipe through a conduit.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. The motor drives the gear to mesh with the gear ring, which drives the ring frame and its internal filter plate to rotate in the first housing, so that all areas of the filter plate surface can be washed by the water spray pipe, achieving thorough cleaning without dead angles without the need for frequent disassembly of the filter plate; at the same time, the liquid supply pump delivers the cleaning liquid from the water tank to the fixed pipe through the conduit, and forms a backwash water flow through the multi-hole spray pipe. The combined effect of rotational motion and water flow impact significantly improves the efficiency of impurity removal.
[0019] 2. A conical sleeve is installed behind the filter plate to create a flow-guiding effect, so that the fine impurities after rinsing are discharged with the water flow in a vortex, avoiding the deposition of impurities in the first shell and causing secondary blockage.
[0020] 3. The first and second housings are connected by flange bolts, which allows for quick separation of the main body of the equipment from the external pipelines during maintenance, significantly reducing the difficulty of filter plate maintenance. Attached Figure Description

[0026] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0027] like Figure 1 and Figure 2 As shown, the mine drainage equipment disclosed in this embodiment, which is easy to clean, includes a base plate 1, a bottom wheel 2, a water pump 3, a water tank 4, a liquid supply pump 11, and a motor 19.
[0028] Bottom plate 1 is equipped with bottom wheels 2, which are swivel wheels.
[0029] The base plate 1 is equipped with a water pump 3, a water tank 4, a liquid supply pump 11, and a motor 19.
[0030] The water pump 3 has a drain pipe 5 at its outlet end and an inlet pipe 6 at its inlet end. The inlet pipe 6 has a transfer pipe 7 at its inlet end and the transfer pipe 7 is fixed above the base plate 1 by a support rod 8.
[0031] One end of the transfer pipe 7 is provided with a first housing 9, and one end of the water inlet pipe 6 is provided with a second housing 10. The first housing and the second housing are fixed and connected by the circumferential mating flange and bolts.
[0032] like Figure 3As shown, an annular frame 15 is rotatably mounted on the housing of the first housing 9. Annular blocks are installed on both sides of the annular frame. An annular groove for the annular blocks to engage is provided at the contact position between the first housing and the annular frame. The annular blocks are embedded in the annular groove to achieve a rotatable connection.
[0033] The outer ring of the ring frame 15 is provided with a toothed ring 18, and the output end of the motor 19 is provided with a gear 20 that meshes with the toothed ring. The motor is a servo motor.
[0034] The annular frame 15 contains a filter plate 16 located inside the first housing 9.
[0035] A conical sleeve 17 is provided on the side of the ring frame 15 away from the water inlet pipe 6, and the conical sleeve is located inside the first housing 9. The conical sleeve prevents small impurities from accumulating inside the first housing after cleaning.
[0036] The outer wall of the second housing 10 is provided with a fixed pipe 12, and the water outlet end of the fixed pipe is provided with a water spray pipe 14 that is inserted into the second housing and located on one side of the filter plate 16.
