It is mainly used to separate solids and liquids in a mixture, and is particularly suitable for treating liquids containing medicinal residues or suspended matters. The pressure filter tank for pharmaceutical production usually consists of a tank body, a filter screen, an extrusion mechanism, inlet and outlet pipes, a control system, etc. The tank body is the main part of the device and is used to hold the material to be pressure-filtered; the filter screen is located inside the tank body and is used to filter the material to separate solids and liquids; the extrusion mechanism applies pressure to make the liquid in the material flow out through the filter screen, while the solids are retained on the surface of the filter screen or inside the tank body. Therefore, during the pressure filtration process, in order to avoid too much solid residue affecting the flow rate of the liquid, it is necessary to stop the machine to remove the solids, which affects the pressure filtration efficiency. Therefore, the inventor proposes a pressure filter tank for pharmaceutical production. Content of the Utility Model

A feed pipe 6 is provided above the main body 1 of the pressure filter tank, and a corresponding discharge pipe 5 is provided at the bottom. A chassis 7 is fixed to the bottom of the main body 1 of the pressure filter tank.

[0023] Referring to Figure 2 , a pressure filtering chamber 11 and a filtering chamber 9 are provided inside the main body 1 of the pressure filter tank between the feed pipe 6 and the discharge pipe 5. The pressure filtering chamber 11 is arranged above the filtering chamber 9 and is communicated with each other. A pressing wheel 8 is arranged inside the pressure filtering chamber 11; the filtering component 3 is slidably installed along the outside of the main body 1 of the pressure filter tank into the filtering chamber 9. There is an opening on the outer wall of the main body 1 of the pressure filter tank for installing the filtering component 3, and a baffle 4 is hinged at the opening. A driving motor 2 is fixedly installed on the outer wall of the main body 1 of the pressure filter tank, and the output shaft of the driving motor 2 is fixedly connected to the pressing wheel 8. After the medicinal materials enter the inside of the pressure filtering chamber 11 along the feed pipe 6, the drainage slope 12 guides the medicinal materials towards the pressing wheel 8 in a concentrated manner. After the pressing wheel 8 presses the medicinal materials, the pressed liquid passes through the filtering component 3 and flows out along the discharge pipe 5.

[0024] Referring to Figure 3 , the filtering component 3 includes a filter plate 13, and a filter net 14 is arranged inside the filter plate 13. An inclined drainage slope 12 is provided above the pressure filtering chamber 11 near the feed pipe 6. The pressing wheel 8 is arranged below the drainage slope 12, and there are two groups of pressing wheels 8 distributed at intervals. Thanks to the setting of the two groups of filtering components 3, the operation of intercepting the medicinal residues can be carried out alternately. When the upper filtering component 3 is used for a long time, the lower filtering component 3 can be installed, and then the upper filtering component 3 can be removed. On the contrary, when the lower filtering component 3 is used for a long time, the upper filtering component 3 can be installed, and then the lower filtering component 3 can be removed. When pressing the medicinal materials, there is no need to stop the machine to process the medicinal residues. After the filtering component 3 is taken out, the medicinal residues are cleaned in time, and it can be directly installed during the next replacement operation, which is convenient to operate.

[0025] Refer to Figure 2 、 Figure 4 On the inner wall of the filtration chamber 9, a magnetic attraction strip 10 is horizontally and fixedly installed. On the surface of the filter plate 13 facing the inside of the pressure filtration tank main body 1, a magnetic strip 15 is provided, and the magnetic strip 15 is adapted to the magnetic attraction strip 10. The filter plate 13 is adsorbed inside the pressure filtration tank main body 1 through the cooperation of the magnetic strip 15 and the magnetic attraction strip 10, improving the use stability and facilitating disassembly and assembly.

[0026] Working principle: When in use, first put the medicinal materials to be pressure-filtered into the inside of the pressure filtration tank main body 1 along the feed pipe 6. Subsequently, start the driving motor 2, and the driving motor 2 drives the pressure wheel 8 to rotate. The pressure wheel 8 has a rotational force to extrude the passing medicinal materials. After the medicinal materials enter the pressure filtration chamber 11 along the feed pipe 6, the diversion slope 12 guides the medicinal materials towards the pressure wheel 8. After the pressure wheel 8 presses the medicinal materials, the pressed liquid passes through the filtration assembly 3 and flows out along the discharge pipe 5, while the extruded medicinal material residues are intercepted by the filter net 14. In a specific implementation, two sets of filtration assemblies 3 can be installed on the pressure filtration tank main body 1, and the two sets of filtration assemblies 3 are separately installed. When the upper filtration assembly 3 is used for a long time, the lower filtration assembly 3 can be installed, and then the upper filtration assembly 3 can be removed. On the contrary, when the lower filtration assembly 3 is used for a long time, the upper filtration assembly 3 can be installed, and then the lower filtration assembly 3 can be removed, so that when pressure-filtering medicinal materials, there is no need to stop the machine to handle the medicinal residues. The medicinal liquid directly passes through the filter net 14 and flows out, while the medicinal residues are intercepted. By replacing the filter plate 13, the filter residues can be cleaned. A baffle 4 is provided on the pressure filtration tank main body 1. When the filtration assembly 3 is not installed, the baffle 4 is closed to seal the pressure filtration tank main body 1, improving the sealing effect. The filter plate 13 is adsorbed inside the pressure filtration tank main body 1 through the cooperation of the magnetic strip 15 and the magnetic attraction strip 10, improving the use stability. When it needs to be removed, it can be directly pulled out.
