[0034] The interior of the purification chamber 210 houses two power components 250 designed to work in conjunction with the connecting plate 213 to accelerate the movement of impurities to the right. These power components 250 are located below the connecting plate 213. Each power component 250 includes a rotating drum 251. Multiple protruding rods 252 for controlling the vibration of the connecting plate 213 are fixedly mounted on the outer wall of the rotating drum 251. A rotating rod 253 is fixedly mounted in the middle of the rotating drum 251. A pulley 254 is fixedly mounted at one end of the rotating rod 253. A motor 10 is mounted at one end of one of the rotating rods 253, and the motor 10 is mounted outside the purification chamber 210. A belt 20 is fitted around the middle of the pulley 254. The motor 10 drives one of the rotating rods 253. When the 53 rotates, the pulley 254 at one end of the rotating rod 253, together with the belt 20, drives a power component 250 to rotate, and the rotating rod 253 simultaneously drives the rotating drum 251 to rotate, so that the protruding rod 252 on the outer wall of the rotating drum 251 intermittently touches the connecting plate 213, thereby causing the connecting plate 213 to vibrate, so that the impurities on the upper end of the connecting plate 213 can move towards the slag discharge pipe 260, and avoid impurities accumulating on one side of the side filter membrane 211.
