The mixed wastewater enters the liquid filter 141 with the filter cartridge 145 installed through the outlet pipe 134 for filtration treatment and is returned to the water ring vacuum pump 121 for recycling through the circulation pump 146. This can effectively reduce the equipment load, extend the equipment life, and improve the gas suction and purification efficiency through step-by-step filtration and separation.

[0035] Working Principle: During operation, the first cyclone separator 3 and the second cyclone separator 4 separate most of the sucked material from the conveying gas. The pneumatic discharge ball valve 61 allows switching control between the first cyclone separator 3 and the second cyclone separator 4 for continuous unloading. The material sensor 63 inside the collection hopper 62 monitors the material quantity. When the material reaches its limit, the control valve 64 opens, and the motor 66 inside the discharge pipe 65 drives the conveying auger 67 for automated unloading, ensuring continuous and efficient dust removal from the sucked airflow. The high-efficiency dust collector 91 handles the gas containing fine particles from the first cyclone separator 3 and the second cyclone separator 4. To improve dust removal efficiency, two high-efficiency dust collectors 91 can be connected in series for two-stage dust removal. Discharge is done manually; the pneumatic flap discharge valve 94 is opened to release the material during cleaning. During the process, the electric lifting rod 112 drives the backwash pipe 114 with multiple nozzles 116 to realize the automated timed backwash cleaning of multiple funnel-shaped filter screens of the air filter 96. This eliminates the need for manual cleaning, improves efficiency, and ensures the dust removal effect of the air filter 96. The dust-laden gas enters the water ring vacuum pump 121 through the first connecting pipe 15 and mixes thoroughly with water. The dust in the gas is adhered by the water and enters the bottom of the separation tank 131 through the liquid inlet pump 132 to settle. The clean gas is discharged through the clean gas outlet pipe 133. The mixed wastewater enters the liquid filter 141 equipped with filter cartridges 145 through the liquid outlet pipe 134 for filtration treatment, and then returns to the water ring vacuum pump 121 for recycling through the circulation pump 146. This process effectively reduces the equipment load, extends the equipment life, and improves the gas extraction and purification efficiency through step-by-step filtration and separation.
