In the pharmaceutical process, raw materials need to be pretreated to improve pharmaceutical work efficiency and facilitate the rapid implementation of the pharmaceutical process. In the context of the pharmaceutical industry strictly adhering to GMP regulations and high-quality production standards, the continuity, cleanliness and precise control of the drug pretreatment process directly determine the quality of drugs and production efficiency. Traditional pharmaceutical processes rely on separate equipment such as filters, washing kettles, and drying ovens to operate in stages, and materials need to be transferred multiple times. This not only prolongs the processing cycle and increases energy consumption, but is also more likely to cause cross-contamination and loss of active ingredients. It is difficult to adapt to the strict requirements of innovative drugs (such as biologics and highly active APIs) for aseptic operation and process stability.

[0003] The filter holes of the existing drug pretreatment flip filter washing and drying machines are mostly easily clogged by solid particles, resulting in a significant decrease in filtration efficiency.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention solves the problem of easy clogging of the filter screen by arranging the cooperation of structures such as the recoil plate and the recoil rod. The fourth motor is started to make the recoil plate drive the recoil rod to reciprocate and repeatedly recoil the filter holes, wherein the recoil rod can push out the solid particles stuck in the filter holes, preventing the accumulation of impurities in the filter holes and causing the filter screen to be clogged. This helps to maintain the permeability of the filter screen, ensure the stability of the filtration efficiency, and reduce the wear and corrosion of the filter screen by impurities, avoiding the situation that the filter screen needs to be frequently replaced due to clogging of the filter screen, thereby extending the service life of the filter screen, reducing the maintenance cost of the equipment, and ensuring the smoothness of the drainage and filtration links, helping to maintain the overall stability and reliability of the equipment, and reducing equipment failures and downtime caused by problems such as poor drainage or filter clogging. The present invention improves the filtration efficiency by arranging the cooperation of structures such as the cam and the rotating plate. The rotation of the cam causes one end of the rotating plate close to the filter screen to abut against the bottom of the filter screen through transmission, exerting an impact force on the filter screen, causing the filter screen to vibrate, preventing particles from forming a tight filter cake layer on the surface of the filter screen, keeping the filter holes unobstructed, ensuring continuous and efficient filtration, and helping to break up the agglomeration of particles in the liquid, so that the liquid can pass through the filter screen more smoothly, accelerating the solid-liquid separation speed, and at the same time, making the particles more evenly distributed on the filter screen, avoiding local blockage and improving the overall filtration efficiency. The folded air bag located above the rotating plate will play a certain buffering role on the rotating plate under the action of air pressure, which can reduce the impact strength of the rotating plate on the filter screen, avoid damage to the filter screen due to excessive impact, thereby extending the service life of the filter screen and reducing equipment maintenance costs. The present invention cooperates with structures such as a recoil airbag and a spray hole. During the upward movement of the connecting plate, the recoil airbag is squeezed, so that the gas in the recoil airbag enters the inside of the diverter ring through the gas transmission groove, and then pushes the one-way valve in the spray hole to open it, and sprays it out from a number of spray holes. During the filtration process, an impact force can be applied to the solid particles in the processing chamber. The impact force of the gas can break the agglomeration between the particles, disperse the particles, increase the contact area between the particles and the liquid, help to improve the filtration effect, and also facilitate subsequent washing, drying and other processing steps. In addition, the impact force can promote the particles to suspend and move better in the liquid, so that the liquid can pass through the filter screen more smoothly, thereby improving the efficiency and quality of solid-liquid separation and obtaining a clearer filtrate and a drier filter cake.

At this time, the recoil plate 106 will move downward under its own gravity and the pressure of the sewage and solid particles on the top of the filter screen 101. This cycle can be repeated to repeatedly backwash the filter screen 101; At the same time, the rotation of the cam 104 will drive the half gear 202 to rotate under the transmission of the two mutually meshing bevel gears 201, and the rotation of the half gear 202 will drive the driven gear 203 meshing with it to rotate, and the rotation of the driven gear 203 will drive the driven gear 203 to rotate, so that the end of the rotating plate 204 close to the filter 101 will rotate in the direction away from the filter 101, and squeeze the folded airbag 206 and the spiral elastic member 207 at the bottom thereof, so that the gas in the folded airbag 206 enters the folded airbag 206 above the rotating plate 204 through the ventilation groove 407. At the same time, the rotation of the rotating plate 204 will also The scroll elastic member 205 on its side is compressed. When the teeth on the half gear 202 rotate to a position where they are disengaged from the driven gear 203, the rotating plate 204 rotates in the opposite direction under the elastic force of the scroll elastic member 205 and the spiral elastic member 207, causing the end of the rotating plate 204 close to the filter 101 to abut against the bottom of the filter 101, exerting an impact force on the filter 101. The folded airbags 206 located above the rotating plate 204 provide a certain cushioning effect on the rotating plate 204 under the action of air pressure. Both folded airbags 206 can prevent liquid from entering the second rotating groove 316. During the upward movement of the connecting plate 105, the recoil airbag 109 is squeezed, so that the gas in the recoil airbag 109 enters the diverter ring 402 through the gas delivery groove 401, and then pushes the one-way valve 406 in the nozzle hole 403 to open, and is sprayed out from a plurality of nozzle holes 403, which can exert an impact force on the solid particles in the processing chamber 314 during the filtration process. The impact force of the gas can break the agglomeration between the particles and disperse the particles. During the downward movement of the connecting plate 105, the recoil airbag 109 is driven to expand, and a negative pressure is generated in the gas delivery groove 401, so that the valve groove 405 in the nozzle hole 403 is closed under the action of the negative pressure, and the valve groove 405 in the air intake hole 404 is opened under the action of the negative pressure, and the air outside the processing chamber 301 is sucked into the recoil airbag 109 through the air intake hole 404 and the gas delivery groove 401; After the filtration is completed, the baffle 409 is used to cover the top of the filter screen 101, and then clean water is injected into the processing chamber 314 through the feed pipe 304, and the lifting blade 307 is rotated to clean the filter cake, and then the above filtration steps are repeated. After the filtration, hot air is injected into the guide pipe 303 through the circulator 302 to increase the temperature in the processing chamber 314, and the lifting blade 307 is used to stir the filter cake to speed up the drying speed, and then it is cooled by cold air. Finally, the discharge valve 311 is moved away from the processing chamber 314 through the cylinder 310, so that the processing chamber 314 is connected to the discharge port 312. At this time, the rotation of the lifting blade 307 will discharge the pretreated medicine from the discharge port 312.
