DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 6 In this embodiment, a natural gas impurity separation and recovery device is provided, which includes a purification box 1 and an air inlet pipe 2. The front end surface of the purification box 1 is equipped with the air inlet pipe 2, and the bottom of the purification box 1 is equipped with an air outlet pipe 11. The inner wall of the purification box 1 is sequentially arranged with a first filter screen 12 and a second filter screen 13 from top to bottom. The aperture of the first filter screen 12 is larger than the aperture of the second filter screen 13. The left and right side walls of the purification box 1 are symmetrically opened with a plurality of suction ports 14. The suction ports 14 are symmetrically arranged up and down. A fixed box 15 is installed at the outer end of the suction port 14. A dust collector 16 is installed at the outer end of the fixed box 15. The first filter screen 1 2 and the second filter 13 gradually decrease in height from the front to the back. When working, natural gas enters the purification box 1 through the intake pipe 2, and the natural gas impurities are filtered through the first filter 12 and the second filter 13. A variety of filter structures are used to ensure the filtering effect, and the filter is arranged obliquely so that the impurities roll on the filter surface to avoid mesh blockage. At the same time, the vacuum cleaner 16 is started to suck the impurities on the first filter 12 and the second filter 13 through the suction port 14 for recycling, so as to facilitate cleaning and enable the purification box 1 to perform normal operation for a long time.

[0021] A fixed cavity 17 is installed on the rear end face of the purification box 1, and an adjusting screw 18 is rotatably installed on the left end face of the fixed cavity 17 through a bearing, and an adjusting motor 19 is installed on the right end face of the adjusting screw 18. The adjusting screw 18 is symmetrically screwed with an adjusting slider, and a connecting frame 21 is installed on the front end face of the adjusting slider. A piston 22 is arranged on the outer end of the connecting frame 21, and the piston 22 is arranged in the suction port 14. The adjusting screw 18 is symmetrical on the left and right, and the thread directions of the piston 22 are opposite. When working, the piston 22 seals the suction port 14. When dust removal is performed, the adjusting motor 19 is started, driving the adjusting screw 18 to rotate, so that the connecting frame 21 moves inward, thereby the piston 22 moves inward, and the suction port 14 is opened. When the vacuum cleaner 16 is working, the dust on the upper surfaces of the first filter 12 and the second filter 13 can be recovered.

[0022] An upper pipe 23 is installed on the upper end surface of the fixed cavity 17, and a lower pipe is installed at the bottom of the fixed cavity 17. The upper pipe 23 and the lower pipe are connected through a control valve. During operation, a small amount of dust will enter the fixed cavity 17. By opening the control valve, water is added to the upper pipe 23 for cleaning, and then the sewage is discharged through the lower pipe.

[0023] A fixed cone 24 is installed at the outer end of the piston 22, and an outer scraper 25 is installed on the outer wall of the fixed cone 24. The outer scraper 25 is arranged in the suction port 14. During operation, when the piston 22 moves, the fixed cone 24 can break up the particles blocking the suction port 14, and the outer scraper 25 can scrape the dust attached to the inner wall of the suction port 14, so as to facilitate the vacuum cleaner 16 to recycle it.

[0024] During specific operation, natural gas enters the purification box 1 through the intake pipe 2, and the natural gas impurities are filtered through the first filter 12 and the second filter 13. A variety of filter structures are used to ensure the filtering effect, and the filter is arranged at an angle so that the impurities roll on the filter surface to avoid mesh blockage. When natural gas is not introduced, the adjustment motor 19 is started to drive the adjustment screw 18 to rotate, so that the connecting frame 21 moves inward, thereby the piston 22 moves inward, the suction port 14 is opened, and the vacuum cleaner 16 is started to suck in the impurities on the first filter 12 and the second filter 13 through the suction port 14 for recycling, thereby facilitating cleaning and allowing the purification box 1 to perform normal operation for a long time.

[0025] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
