Description

Technical Field

[0001] This utility model relates to the field of water accumulation cleaning technology, specifically a water accumulation cleaning device for coal mine mining operations. Background Technology

[0002] In coal mining operations, water removal is a common and important task. Because coal mine water contains numerous impurities, both small and large particles can severely damage the water pumps in the drainage system, causing them to malfunction and significantly impacting the system's efficiency.

[0003] Because it is used in the special environment of coal mines, the filter structure of the water cleaning device needs to be disassembled frequently for cleaning. Although the existing water cleaning device has optimized the disassembly of the filter structure, making it easier to disassemble, the total time wasted is still too long. This total time includes the disassembly time of the workers plus the cleaning time inside the filter structure, ultimately resulting in low efficiency of water cleaning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a coal mine working surface water cleaning device. When the working surface water cleaning device is used, if one of the alternating filter valves needs to be cleaned due to impurities, it can be quickly replaced by sliding. The total time wasted by this device is short, which is the time required to replace the alternating filter valve, thus making its working efficiency higher.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A device for cleaning up surface water in coal mining operations includes a water pumping pipe with a filter connector connected to it.

[0007] The filter connector contains two sets of alternating filter valves, which are connected to each other by reinforcing ribs. Each set of alternating filter valves contains a filter screen.

[0008] The filter connector is equipped with slide grooves at both the top and bottom. Both ends of the two sets of alternating filter valves are connected to flanges that slide within the slide grooves. By sliding the flanges within the slide grooves, different alternating filter valves can be alternately replaced and concentrically connected to the water pumping pipe.

[0009] Using the above solution, when the coal mine working area water cleaning device is in use, if one of the alternating filter valves needs to be cleaned due to impurities, it can be quickly replaced by sliding. The total time wasted by this device is short, which is the time required to replace the alternating filter valve. After replacement, the impurities in the alternating filter valve are cleaned, which makes its working efficiency higher.

[0010] As a preferred embodiment of a coal mine working surface water cleaning device, an annular groove is provided on the side surface of the flange, and a sealing ring is installed in the annular groove for limiting the flange. The flange is sealed to the filter connector through the sealing ring.

[0011] In order to ensure the sealing performance of the alternating filter valve and the water pumping pipe after docking, a sealing ring is installed between the two to improve their sealing performance after docking.

[0012] As a preferred embodiment of a coal mine working area water cleaning device, push-pull handles are connected to both sides of two sets of alternating filter valves.

[0013] With the above solution, in order to facilitate the sliding of the alternating filter valve, the push-pull handle can be operated to alternate the filter valve when it is sliding.

[0014] As a preferred embodiment of a coal mine working surface water cleaning device, a guide hole is provided at the edge of the filter screen, and a guide rod that cooperates with the guide hole is fixed inside the alternating filter valve. The filter screen can slide along the guide rod and can be removed from the alternating filter valve.

[0015] Using the above solution, in order to quickly and easily clean the impurities inside the alternating filter valve, the filter screen can be pushed directly along the guide rod, and all the impurities inside the alternating filter valve can be pushed out together by the filter screen. Then the filter valve can be installed. This method is both convenient and efficient.

[0016] As a preferred embodiment of a coal mine working surface water cleaning device, the filter connector has guide posts fixed on the upper surface of the two sliding grooves at its top. Push plates are slidably installed on the guide posts, and springs that push the push plates downward are fitted on the guide posts. A C-shaped pin is connected between the two push plates, and the lower end of the C-shaped pin is round.

[0017] The flange surface has a socket for use with a C-shaped pin; when the C-shaped pin is inserted into the socket, the alternating filter valve and the water pumping pipe are perfectly concentrically connected.

[0018] Using the above solution, in order to facilitate the positioning of the alternating filter valve, the alternating filter valve can be fixed by inserting a C-shaped pin into the socket. The C-shaped pin can fix both ends of the alternating filter valve at the same time, making the operation more convenient and quick. When disassembling the alternating filter valve, simply pull up the C-shaped pin to make it disengage from the socket.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] 1. When the coal mine working area water cleaning device is in use, if one of the alternating filter valves needs to be cleaned due to impurities, it can be quickly replaced by sliding. The total time wasted by this device is short, which is the time required to replace the alternating filter valve. After replacement, the impurities in the alternating filter valve are cleaned, which makes its working efficiency higher.

[0021] 2. To ensure the sealing performance of the alternating filter valve and the water pumping pipe after connection, a sealing ring is installed between them to improve the sealing performance after connection.

[0022] 3. To facilitate the sliding of the alternating filter valve, the push-pull handle can be operated to alternate the filter valve while it is sliding.

[0023] 4. To facilitate quick and easy cleaning of impurities inside the alternating filter valve, the filter screen can be pushed directly along the guide rod to push out all impurities inside the alternating filter valve. Then the filter valve can be installed. This method is both convenient and efficient.

[0024] 5. To facilitate the positioning of the alternating filter valve, the C-shaped pin can be inserted into the socket to fix the alternating filter valve. The C-shaped pin fixes both ends of the alternating filter valve at the same time, making operation more convenient and quick. When disassembling the alternating filter valve, simply pull up the C-shaped pin to disengage it from the socket. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 6 As shown, a coal mine working area water cleaning device includes a water pumping pipe 1, with a filter connector 2 connected to the pipe 1. Two sets of alternating filter valves 3 are installed inside the filter connector 2, connected to each other by reinforcing ribs 4. Each set of alternating filter valves 3 contains a filter screen 5. Slide grooves 6 are installed above and below the filter connector 2. Flanges 7 that slide within the slide grooves 6 are connected to both ends of the two sets of alternating filter valves 3. By sliding the flanges 7 within the slide grooves 6, different alternating filter valves 3 can be alternately replaced and concentrically connected to the water pumping pipe 1. When this coal mine working area water cleaning device is in use, if one of the alternating filter valves 3 needs cleaning due to blockage by impurities, it can be quickly replaced by sliding. The total time lost is short, consisting of the time required to replace the alternating filter valve 3. The device further improves its working efficiency by cleaning the impurities within the alternating filter valve 3 after replacement.

[0036] like Figures 5 to 6 As shown, an annular groove is formed on the side surface of flange 7, and a sealing ring 8 is installed within the annular groove for limiting the connection. Flange 7 is sealed to filter connector 2 through sealing ring 8. In order to ensure the sealing performance between alternating filter valve 3 and water pumping pipe 1 after docking, sealing ring 8 is installed between them, thereby improving the sealing performance after docking.

[0037] like Figures 5 to 6 As shown, push-pull handles 9 are connected to both sides of the two sets of alternating filter valves 3. To facilitate the sliding of the alternating filter valves 3, the push-pull handles 9 can be operated to alternate them while sliding the alternating filter valves 3.

[0038] like Figure 4 , Figure 7 As shown, a guide hole 10 is provided at the edge of the filter screen 5. A guide rod 11 that cooperates with the guide hole 10 is fixed inside the alternating filter valve 3. The filter screen 5 can slide along the guide rod 11 and can be removed from the alternating filter valve 3. In order to facilitate and quickly clean the impurities in the alternating filter valve 3, the filter screen 5 can be pushed directly along the guide rod 11 to push out all the impurities in the alternating filter valve 3 together. Then the filter valve can be installed. This is both convenient and efficient.

[0039] like Figure 4 As shown, the filter connector 2 has guide posts 12 fixed on the upper surfaces of the two sliding grooves 6 at its top. Push plates 13 are slidably mounted on the guide posts 12, and springs 14 are fitted on the guide posts 12 to push the push plates 13 downward. A C-shaped pin 15 is connected between the two push plates 13, and the lower end of the C-shaped pin 15 is rounded. The surface of the flange 7 has a socket 16 for use with the C-shaped pin 15. When the C-shaped pin 15 is inserted into the socket 16, the alternating filter valve 3 and the water pipe 1 are concentrically connected. To facilitate the positioning of the alternating filter valve 3, the alternating filter valve 3 can be fixed by inserting the C-shaped pin 15 into the socket 16. The C-shaped pin 15 simultaneously fixes both ends of the alternating filter valve 3, making operation more convenient and quick. When disassembling the alternating filter valve 3, simply pull up the C-shaped pin 15 until it is disengaged from the socket 16.

[0040] The working principle of this utility model:

[0041] In operation, a water pump drives the pumping pipe 1 to extract accumulated water from the mining face. Due to the high level of impurities in the water, workers need to frequently replace the alternating filter valve 3.

[0042] When replacing the alternating filter valve 3, first pull up the C-shaped pin 15 and disengage it from the socket 16. Then, operate the push-pull handle 9 to quickly push the alternating filter valve 3 along the slide groove 6, thereby connecting the other alternating filter valve 3 concentrically with the water pipe 1 until the C-shaped pin 15 is inserted into the socket 16. This completes the replacement of the alternating filter valve 3. The total time wasted by this device is relatively short. This total time is the time required to replace the alternating filter valve 3. After replacement, the impurities inside the alternating filter valve 3 are cleaned, which makes its working efficiency even higher.

[0043] After replacing the alternating filter valve 3, the filter screen 5 can be pushed directly along the guide rod 11 to push out all the impurities in the alternating filter valve 3. Then the filter valve can be installed. It is both convenient and efficient.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
