Technical Field

[0001] The utility model relates to the technical field of coalbed methane, in particular to a coalbed methane filtering device. Background Technique

[0002] Coalbed methane refers to hydrocarbon gas stored in coal seams, with methane as the main component, mainly adsorbed on the surface of coal matrix particles, partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal and belongs to unconventional natural gas.

[0003] In this regard, Chinese Patent Application No.: CN219942154U discloses a coalbed methane filtering device, including a filtering box. An air inlet pipe and an air outlet pipe are provided on the filtering box. A filtering component is provided inside the filtering box. A cleaning component is provided on the filtering box. A filter screen is provided inside the filtering box. A drain pipe is provided at the bottom end of the filtering box. The filtering component includes four limiting grooves symmetrically opened on both side walls of the inner cavity of the filtering box. Limiting plates are slidably arranged in the four limiting grooves. Filtering plates are jointly connected between the two limiting plates on the same side. Through the setting of the filtering component, the coalbed methane can be filtered, and dust particle impurities such as coal powder and sand carried in the coalbed methane can be screened, so as to ensure the purity of the coalbed methane. With the setting of the cleaning component, the filtering plates can be cleaned, so as to avoid the problem that the mesh holes of the filtering plates are blocked by dust particle impurities such as coal powder and sand carried in the coalbed methane, and manual cleaning is not required.

[0004] However, in actual use, after the two groups of filtering plates are sequentially filtered, the impurities will still accumulate inside the drain pipe after the filtering plates are cleaned. Therefore, when the next group of filtering plates are placed inside the drain pipe, impurities will adhere, resulting in poor cleaning effect of the filtering plates. At the same time, the internal filter screen cannot be disassembled. Therefore, improving and modifying the above problems has become an urgent problem to be solved at present. Summary of the Invention

A sliding groove is opened on the right surface of the filter box 1, and the sliding groove is adapted to the second filter screen 20. By installing the second filter screen 20 inside the clamping groove 19, at this time, the second filter screen 20 is fixedly installed inside the clamping groove 19, and at the same time, the second filter screen 20 is in communication with the clamping groove 19. Therefore, the gas can be filtered again through the second filter screen 20, and after the filtering is completed, the handle 21 can be pulled out through the sliding groove on the right side of the filter box 1 for cleaning;

[0026] The side block 7 is installed on the left surface of the filter plate 5. A telescopic rod 8 is fixedly connected to the lower surface of the side block 7. The telescopic rod 8 is installed on the upper surface of the filter box 1. A cleaning frame 9 is arranged at the lower end of the filter box 1. An adaptation slot 10 is opened on the right side of the cleaning frame 9. A storage box 11 is arranged inside the adaptation slot 10. A water outlet pipe 12 is arranged on the left surface of the storage box 11. A water delivery hose 13 is arranged on the back surface of the storage box 11. A rotating shaft 14 is installed inside the cleaning frame 9.

At the same time, when the filter plate 5 moves into the cleaning frame 9, the coalbed methane can also be filtered by the first filter screen 6.

[0027] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. First, start to intake air through the intake pipe 2, and then the filter plate 5 and the first filter screen 6 can filter out impurities in the gas. When cleaning, start the telescopic rod 8. The telescopic rod 8 can drive the filter plate 5 to move downward, thus driving the first filter screen 6 downward. At this time, the filter plate 5 will move into the cleaning frame 9, and then convey water source into the inside of the water supply hose 13. Subsequently, spray water from the storage tank 11 and the water outlet pipe 12 onto the right surface of the first filter screen 6 to clean the impurities inside the first filter screen 6. At the same time, start the motor body 15. The motor body 15 drives the rotating shaft 14 to rotate, and then the rotating shaft 14 drives the mounting ring 16 and the beating block 17 to rotate. The rotating beating block 17 can beat the first filter screen 6 to disperse the impurities inside the first filter screen 6. The overall effect is good. Then, at the bottom end of the cleaning frame 9 after cleaning, there is a drain pipe, and the opening and closing of the drain pipe are controlled by a solenoid valve, so that the cleaned water and impurities can be quickly cleaned. By installing a second filter screen 20 inside the card slot 19, at this time, the second filter screen 20 is fixedly installed inside the card slot 19, and the second filter screen 20 is interconnected with the card slot 19. Therefore, the second filter screen 20 can filter the gas again. After the filtration is completed, just pull out the handle 21 from the right chute of the filter box 1 for cleaning.
