[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4A coal press inlet filtering and purification device includes a body 1, an air intake pipe 2, a lifting assembly and a filtering assembly. The air intake pipe 2 is provided at one end of the body 1. Support covers 10 are symmetrically provided at the upper and lower ends of the air intake pipe 2. The lifting assembly includes a cover 3, a motor 4, a worm gear 5, a worm 6 and a screw 7. Two sets of the support covers 10 are provided with an active cavity that is connected to the air intake pipe 2. The cover 3 is provided above the support cover 10 located above. The worm 6 is provided in the cover 3. And two groups of worm gears 5, the worm 6 is meshed with the worm gear 5, and two groups of symmetrically arranged screws 7 are also provided in the support cover 10 located above, and the screws 7 pass through the support cover 10 and the cover body 3 and are connected to the center of the worm gear 5. A filter assembly is also provided in the active cavity, and the filter assembly includes a sliding frame 8 and a filter frame 9. The sliding frame 8 is provided with a screw groove adapted to the screw 7, and the sliding frame 8 is embedded with several groups of filter frames 9 adapted to the inner wall of the intake pipe 2.

[0024] Dust-laden coal gas enters the filtration and purification device through the intake pipe 2. Support covers 10 at the upper and lower ends of the intake pipe 2 provide space for the subsequent installation and protection of the lifting and filtering components. The dust-laden gas first contacts the filter frames 9 embedded in the slide frame 8. Because the filter frames 9 conform to the inner wall of the intake pipe 2, they provide a large surface area for contact with the gas. The multiple layers of filter frames 9 begin to function, with filters of varying precision gradually filtering the gas from the outer layer to the inner layer. Large impurities are first intercepted by the coarser outer filter. As the gas flows inward, smaller particles are blocked by the finer filters in the middle and inner layers. This results in a gradual filtration process from large to tiny particles, effectively intercepting dust and impurities and improving gas purity. The motor 4 is activated, serving as the power source. The servo motor 4 precisely controls the output speed and torque. The motor 4 drives the worm 6 within the housing 3, which meshes with the worm gear 5, transmitting power to the worm gear 5. The center of worm gear 5 is connected to screw 7. As worm gear 5 rotates, screw 7 begins to rotate synchronously. Motor 4 is equipped with a Roots encoder for quantitative feeding. Screw 7 is adapted to the screw groove on slide frame 8. When screw 7 rotates, slide frame 8 moves up and down along screw 7 within the active cavity through the principle of thread transmission. The height of slide frame 8 is adjusted to ensure that the corresponding filter frame 9 is in the optimal filtering position, improving filtration efficiency and effect, and ensuring the long-term use of the equipment.

[0025] In actual use, the front of the lower support cover 10 is also provided with several groups of hinged doors 11 matched with the filter frame 9, the lower support cover 10 is also provided with a cover 12 for closing the movable cavity, the hinged door 11 is also provided with a handle 13, the filter frame 9 is inserted with the sliding frame 8, initially the sliding frame 8 is at a higher position, when it needs to be replaced, the motor 4 drives the worm 6 to rotate, the worm wheel 5 drives the screw rod 7 to rotate, the sliding frame 8 moves downward until the corresponding filter frame 9 is matched with the hinged door 11, at this time, the hinged door 11 on the front of the lower support cover 10 is opened through the handle 13, since the filter frame 9 and the sliding frame 8 are connected in the form of insertion, the operator can easily insert and pull out the filter frame 9, and the use is convenient.
