The surfaces of the first scraper rod 604 and the second scraper rod 608 are both arc-shaped, and the side walls of the first scraper rod 604 and the second scraper rod 608 are fixedly connected with rubber pads. The arc-shaped scraper rod can make the sand on the surface of the scraper rod more easily gather at the end and fall into the sand box 701. The rubber pad can increase the cleaning efficiency of the scraper rod. The outer surface of the first scraper 604 fits with the outer surface of the filter plate 5. When working, after the valve body 1 is connected to the gas pipeline, the gas flows through the filter plate 5 through the through pipe 4, so that the filter plate 5 filters the sand in the gas. In the process of gas flow, the first fan blade 603 drives the sleeve shaft 602 to rotate on the surface of the main shaft 601. When the sleeve shaft 602 rotates, it drives the first scraper 604 to rotate, so that the first scraper 604 scrapes the surface of the filter plate 5, thereby cleaning the surface of the filter plate 5 and preventing the sand from adhering to the surface of the filter plate 5 and blocking the filter plate 5, thereby affecting the gas transportation efficiency.

The first scraper 604 is rotated to shake off the sand on the surface of the first scraper 604, so that the sand is more quickly separated from the first scraper 604, and then the torsion spring drives the paddle 710 to reset, ready for the next impact, the collecting mechanism 7 includes a first protective shaft 702, the bottom of the first protective shaft 702 is fixedly connected to the inner bottom of the sand box 701, the first protective shaft 702 is provided with a first impact shaft 703 inside, the top of the first impact shaft 703 is fixedly connected to the first connecting shaft 704, the top of the first connecting shaft 704 passes through the top of the first protective shaft 702 and extends to the first Above the first protection shaft 702, the outer surface of the first connecting shaft 704 is provided with a first spring 705, the first spring 705 is located inside the first protection shaft 702, one end of the first spring 705 is located at the inner top of the first protection shaft 702, and the other end is located at the top of the first collision shaft 703, the top of the first connecting shaft 704 is fixedly connected with a sub-magnet 706, the lower surface of the movable sleeve 708 is fixedly connected with a mother magnet 709, and the mother magnet 709 is located above the sub-magnet 706. When working, when the first scraper rod 604 is moved When the paddle 710 is moved, the mother magnet 709 is driven to rotate, so that the mother magnet 709 is separated from the sub-magnet 706. At the same time, the first spring 705 drives the first impact shaft 703 to impact the bottom plate of the sand box 701, so that the sand in the sand box 701 is spread more evenly to prevent it from accumulating at the first connecting port 402 and affecting the collection. Then, when the torsion spring drives the paddle 710 to reset, the mother magnet 709 absorbs the sub-magnet 706 through the attraction of opposite poles of the magnetic blocks, so that the first impact shaft 703 is reset away from the bottom surface of the sand box 701.
