[0002] Filtration equipment for pharmaceutical production can be selected according to different filtration mechanisms and materials to remove solid particles or other impurities from liquids or gases. In pharmaceutical production, filters are usually used to purify drug solutions, culture media, solvents, etc.

[0003] Existing filtering equipment for pharmaceutical production usually consists of a shell, a filter, a liquid inlet pipe and a liquid outlet pipe. The drug liquid is filtered through the filter. When cleaning the filtering equipment, the filter needs to be removed and then rinsed with cleaning water, which makes the cleaning operation cumbersome and inconvenient. Moreover, when filtering the drug liquid, the drug liquid particles are easily accumulated and spread on the filter, making it inconvenient for the drug liquid to pass through the filter. The filtration efficiency of the drug liquid is poor, which makes the filtration time of the drug liquid longer. For this reason, we propose filtering equipment for pharmaceutical production.

The control switch 221 uses a device with a model number of JZF-07 produced by Chint Motor on the market. The control switch 221 can be used to control the scraper 233 to move back and forth.

[0033] Specifically, a plurality of water spray heads are arranged at the bottom of the spray pipe 121, and the water spray heads are common spray heads on the market.

[0034] Furthermore, the spray pipe 121 is matched with the top of the filter screen 210 .

[0035] Furthermore, a pressure strip 234 fixed to the inside of the body 100 is provided on the top of the scraper strip 233, and the pressure strip 234 is made of a stainless steel plate.

[0036] Furthermore, the side wall of the filter screen 210 is provided with a fixing edge 212 that matches the inside of the fixing strip 200 .

[0037] It is worth noting that a limit strip 131 is disposed on the side wall of the locking plate 130 .

[0038] It is worth noting that a long hole is opened in the side wall of the limiting strip 131 , and a fixing column is matched inside the long hole. The fixing column is fixed to the side wall of the body 100 by bolts to limit the locking plate 130 .

[0039] In some embodiments, the electrical components and electrical equipment mentioned above all use external power sources.

[0040] In addition, the circuits, electronic components and modules involved in the utility model are all prior art, and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and method.

[0041] Working principle: When the filter device needs to be cleaned, the body 100 is rotated so that the outer tube 140 of the body 100 rotates to the bottom, and then the locking plate 130 is pulled to the right so that the locking plate 130 is released from the pressure on the rubber tube 142. At this time, the rubber tube 142 is no longer airtight, and then the water inlet pipe 120 is passed through the cleaning water, and the cleaning water is sprayed from the spray pipe 121 onto the filter screen 210 inside the body 100. After the filter screen 210 is cleaned, the cleaning water can be discharged through the rubber tube 142 and then through the outer tube 140, so that the filter screen 210 inside the filter device can be conveniently cleaned without opening the filter. The device takes out the filter screen 210, which saves manpower and increases the convenience of using the filtering device; when filtering the medicinal liquid, the driving motor 220 is set to drive the threaded shaft 230 to rotate, thereby driving the connecting block 232 through the displacement block 231 to make the scraper bar 233 cooperate with the pressure bar 234 to move, so that the scraper bar 234 pushes the particles that cannot be sieved on the filter screen 210 to the inside of the temporary storage tank 211, avoiding the problem that the medicinal liquid particles are spread on the filter screen 210, making it inconvenient for the medicinal liquid to pass through the filter screen 210, thereby improving the filtration efficiency of the medicinal liquid and saving the filtration time of the filtration equipment.
