With the rapid development of the chemical industry towards green and intelligent manufacturing, chemical filtration technology has evolved from simple mechanical separation to multifunctional integrated systems. In actual production, it has been found that high-viscosity materials (such as polymers, resins, and colloids) or materials containing solid particles (such as catalysts and crystals) easily deposit on the filter screen surface, leading to a decrease in filtration efficiency. Traditional filtration devices typically use backwashing or vibration cleaning methods, but backwashing consumes large amounts of water or compressed air and has limited effectiveness for high-viscosity materials; vibration cleaning may damage the filter screen structure and shorten equipment lifespan.

[0018] Operating principle: First, open the feed inlet valve of the outer shell 1 and start the conveying system; materials can enter the reactor in two ways: one is by pressurizing and conveying with a diaphragm pump, which is suitable for materials with high viscosity or high solid content; the other is by vacuum filtration, which is suitable for slurries with good fluidity. After the material has completely entered the outer shell 1, the second motor 5 is started to rotate the central rod 6, which drives the paddle 7 to rotate and stir the material. Then, nitrogen gas is injected into the outer shell 1 through the feed connector for pressure filtration. The pressure is generally controlled within the range of 0.2-0.4 MPa. During the filter press process, the nitrogen pressure must be kept constant, and the state of the material inside the vessel must be monitored through a sight glass or sensor. Then, the discharge connector is opened to start discharging. During the discharge process, the height of the slider is controlled by the first motor 3, which in turn controls the height of the paddle. During the discharge process, ensure that the paddle blades remain within 20cm-50cm below the material surface; ensure that the agitator maintains the optimal contact depth with the material layer; the lowest position of the paddle blades is where the scraper just does not touch the filter screen; during this process, ensure that the scraper does not touch the filter screen. After the unloading operation is completed, the operator should first confirm that there is no material residue at the discharge joint, and then close the discharge joint valve; then open the slag discharge joint and the slag removal joint to connect to the sewage pipe, and then start the first motor 3 to make the slider descend until the scraper touches the top surface of the filter screen. Then the output shaft of the second motor 5 rotates, driving the scraper to scrape off the impurities on the top surface of the filter screen and discharge them from the slag discharge joint 10. Meanwhile, the cross-shaped scraper 13 scrapes off the bottom surface of the filter screen and discharges it from the slag removal joint. After all the impurities are discharged, the filter screen is cleaned and all parts are reset.
