[0002] The high-pressure backwash filter station is a filter device used in the fluid supply system of the underground fully-mechanized mining equipment in coal mines. As the first-level filter at the pump station outlet, it is used to protect various hydraulic components of fully-mechanized mining equipment such as hydraulic supports and scraper conveyors in the harsh environment underground. It prevents mechanical impurities in the hydraulic system, external coal ash dust and other pollutants from causing mechanical damage and seal damage, which may cause malfunctions of hydraulic supports, conveyors and filtering equipment.

[0003] A high-pressure backwashing filter station disclosed in Chinese patent CN216726114U has a simple structure and novel design, which solves the economic loss caused by the inability to separate station A and station B when replacing the high-pressure filter element. At the same time, only one person needs to start the switch to stop the entire station A or station B, which solves the need for several people to open or close the pressure relief valve and the stop valve respectively. This device is suitable for wide promotion. However, while solving the problem, the high-pressure backwashing filter station has the following defects:

[0004] When replacing the high-pressure filter element at station A or station B, four stepper motors need to be started simultaneously, which makes the overall production cost and use cost of the filtration station higher. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1-4As shown, a high-pressure backwashing filter station of the present embodiment comprises an upper transport pipe 1, both ends of the upper transport pipe 1 are fixedly installed with a three-way pipe 2, liquid flows in from the three-way pipe 2 at one end of the upper transport pipe 1, and flows out from the three-way pipe 2 at the other side, a ball valve 3 is arranged inside the three-way pipe 2, a control rod 4 is fixedly connected to the outside of the ball valve 3, the control rod 4 can drive the ball valve 3 to rotate inside the three-way pipe 2, the control rod 4 is rotatably connected to the three-way pipe 2, a gear 5 is fixedly connected to the outside of the control rod 4, an upper support plate 6 is fixedly connected to the outside of the three-way pipe 2, and the top of the upper support plate 6 is fixedly installed There is a hydraulic rod 7, and the output end of the hydraulic rod 7 is fixedly connected to the driving rod 8. The output end of the hydraulic rod 7 passes through the upper support plate 6 and is fixedly connected to the driving rod 8, so that the hydraulic rod 7 can drive the driving rod 8 to move up and down. When the driving rod 8 is in contact with the upper support plate 6, the spherical valve 3 can just rotate 180°. Both ends of the driving rod 8 are fixedly connected with tooth plates 9, and the tooth plates 9 are meshed with the corresponding gears 5. When the driving rod 8 moves, it can drive the two tooth plates 9 to move together, and the two tooth plates 9 drive the two control rods 4 to rotate through the corresponding gears 5.

[0024] Embodiment 1: An arc groove 10 is provided inside the three-way pipe 2, and the ball valve 3 is rotatably connected to the arc groove 10. The ball valve 3 and the arc groove 10 fit together, so that the sealing performance of the ball valve 3 when covering the lower side of the three-way pipe 2 can be guaranteed. An L-shaped groove 11 is provided inside the ball valve 3, and the liquid flowing in from one end of the three-way pipe 2 can flow into the interior of the upper transport pipe 1 under the guidance of the L-shaped groove 11.

[0025] Embodiment 2: A connecting pipe 12 is fixedly connected to the outer side of the three-way pipe 2, and the control rod 4 is rotatably connected to the connecting pipe 12. The connecting pipe 12 can support the control rod 4, so that the control rod 4 can rotate better.

[0026] Embodiment 3: The bottom end of the three-way pipe 2 is fixedly connected with a lower transport pipe 13, a station A 14 is arranged on the outer side of the upper transport pipe 1, and a station B 15 is arranged on the outer side of the lower transport pipe 13. When the upper transport pipe 1 is transporting liquid, the station A 14 can filter impurities in the liquid, and when the lower transport pipe 13 is transporting liquid, the station B 15 can filter impurities in the liquid, and the internal settings of the stations A 14 and B 15 are all existing technologies and will not be introduced in detail here.

[0027] Embodiment 4: A pressure relief mechanism 16 is provided at the top of station A 14 and station B 15. When replacing the high-pressure filter element inside station A 14 or station B 15, the pressure inside station A 14 or station B 15 can be eliminated through the pressure relief mechanism 16 first, thereby making it more convenient to replace the high-pressure filter element.

[0028] Embodiment 5: A lower support plate 17 is fixedly connected to the outer side of the three-way pipe 2, a guide column 18 is fixedly connected between the upper support plate 6 and the lower support plate 17, and the drive rod 8 is movably connected to the guide column 18. When the hydraulic rod 7 drives the drive rod 8, the drive rod 8 can slide up and down on the outer side of the guide column 18.

[0029] Embodiment 6: An upper indicator light 19 is fixedly installed on the top of the upper support plate 6, and an upper switch 20 is provided on the bottom of the upper support plate 6. The upper switch 20 is electrically connected to the upper indicator light 19. When the driving rod 8 is in contact with the upper support plate 6, the upper switch 20 can be squeezed to turn on the upper indicator light 19. At the same time, it is the upper transport pipe 1 that transports the liquid.

[0030] Implementation column 7: A lower indicator light 21 is fixedly installed at the bottom of the lower support plate 17, and a lower switch 22 is provided on the top of the lower support plate 17. The lower switch 22 is electrically connected to the lower indicator light 21. When the driving rod 8 is in contact with the lower support plate 17, the lower switch 22 can be squeezed to turn on the lower indicator light 21. At the same time, it is the lower transport pipe 13 that transports the liquid.

[0031] The working principle of the utility model is as follows: when in use, when it is necessary to replace the high-pressure filter element inside the A station 14, the hydraulic rod 7 is directly driven, so that the hydraulic rod 7 pushes the driving rod 8 downward, and the upper indicator light 19 is turned off when the driving rod 8 no longer squeezes the upper switch 20. As the driving rod 8 continues to move downward, the toothed plates 9 at both ends of the driving rod 8 can drive the corresponding two gears 5 to rotate, and the two gears 5 drive the ball valve 3 to rotate inside the three-way pipe 2 through the control rod 4. When the driving rod 8 contacts the lower support plate 17, the control rod 4 just drives the ball valve 3 to rotate 180°, so that one end of the L-shaped groove 11 is aligned with the lower transport pipe 13, and the ball valve 3 blocks the upper transport pipe 1. At this time, the lower switch 22 forms a passage under the squeezing of the driving rod 8 and supplies power to the lower indicator light 21, so that the lower indicator light 21 is turned on, and then the pressure inside the A station 14 is released through the pressure relief mechanism 16, and the high-pressure filter element inside the A station 14 is replaced.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When it is necessary to replace the high-pressure filter element inside the A station 14, the hydraulic rod 7 is directly started, so that the hydraulic rod 7 pushes the driving rod 8 downward, and the toothed plates 9 arranged at both ends of the driving rod 8 drive the two gears 5 to rotate, so that the two gears 5 drive the corresponding two control rods 4 to rotate, and the two control rods 4 drive the corresponding ball valve 3 to rotate 180° inside the corresponding three-way pipe 2, so that the ball valve 3 can block the port where the three-way pipe 2 is connected to the upper transport pipe 1, and at the same time, the ball valve 3 no longer blocks the port where the three-way pipe 2 is connected to the lower transport pipe 13, so that the liquid does not flow from the inside of the upper transport pipe 1 but directly flows inside the lower transport pipe 13, so that the flow path of the liquid can be changed. In summary, when the flow direction of the liquid is changed, the hydraulic rod 7 can be directly driven, and the entire implementation process does not need to set too many driving devices, so that the overall cost of the filtration station is reduced.

[0034] 2. When the liquid flows in the upper transport pipe 1, the driving rod 8 contacts the upper support plate 6 under the pull of the hydraulic rod 7 and squeezes the upper switch 20, so that the upper indicator light 19 can be in a long-lit state. When the liquid flow path needs to be changed, the driving rod 8 moves downward under the push of the hydraulic rod 7. At the same time, the driving rod 8 no longer squeezes the upper switch 20, and the upper indicator light 19 is directly turned off. When the driving rod 8 contacts the lower support plate 17 and squeezes the lower switch 22, the lower indicator light 21 is in a long-lit state, and the liquid can flow in the lower transport pipe 13. In summary, the setting of the driving rod 8, the upper switch 20, the upper indicator light 19, the lower switch 22, and the lower indicator light 21 allows the operator to more intuitively determine which transport pipe is transporting the liquid, thereby improving the overall practicality of the filtration station.
