[0003] Currently, in the biopharmaceutical process, drug extracts need to be filtered to separate the drug residue from the liquid. Existing traditional extract filtration devices usually inject the extract into the interior of the filter chamber and filter the filtrate through a corresponding filter screen. This filtration method is not only inefficient, but the amount of filter residue generated during the filtration process will gradually increase. The filter residue will easily clog the filter screen and affect the filtration efficiency.
[0004] Based on this, this utility model designs a biopharmaceutical extraction pressure filtration device to solve the above problems. Utility Model Content

The screen body is provided with filter holes, and two horizontal plates are fixedly connected to the bottom of the screen body. Two telescopic rods are symmetrically arranged on each of the two horizontal plates.
[0008] In a preferred embodiment of this utility model, the inner rods of the telescopic rod are all fixedly connected to the bearing plate, and multiple top rods are fixedly connected to the bearing plate, with each top rod correspondingly positioned below a plurality of filter holes.
[0009] As a preferred embodiment of this utility model, the blocking mechanism includes a mounting plate, a blocking block, a silicone layer, and fastening bolts. The blocking block is fixedly connected to the mounting plate, the silicone layer is wrapped with a silicone layer on the outside, and fastening bolts are spirally connected to both sides of the mounting plate.
[0010] As a preferred embodiment of this utility model, the silicone layer is embedded in the discharge hole on the upper box, and the mounting plate is fixedly installed on the side wall of the upper box by fastening bolts.
[0011] As a preferred technical solution of this utility model, the cleaning mechanism includes a telescopic push rod and a push plate. The two telescopic push rods are symmetrically fixedly installed on the left side wall of the upper box. The inner rods of the two telescopic push rods pass through the side wall of the upper box and are fixedly connected to the push plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In use, this utility model utilizes the structural design of the filter screen. When the filter holes on the screen become clogged, the inner rods of the four telescopic rods extend simultaneously, lifting the support plate upwards. This pushes multiple push rods on the support plate into the filter holes, thereby cleaning the filter holes on the screen and preventing clogging. Then, the extension and retraction of the inner rods of the telescopic push rods push the push plate above the filter screen, pushing the filter residue on the screen towards the open discharge hole, allowing the filter residue to be discharged through the discharge hole, thus facilitating the cleaning of the filter plate on the filter device.
[0016] 2. When in use, this utility model can perform secondary filtration of the extract after pressure filtration through the conical fine filter cylinder provided on the liquid receiving plate, so as to ensure that a relatively pure extract is obtained and achieve a better filtration effect. Furthermore, the detachable design of the lower and upper chambers facilitates regular cleaning of the conical fine filter cylinder and easy replacement and maintenance of the filter screen, making it highly practical.

A cleaning mechanism 9 is provided on the right side of the upper housing 6. The pressure filtration mechanism 10 is provided at the upper end of the upper housing 6.
[0030] The conical fine filter cartridge 4 installed in the lower chamber 1 enables secondary filtration of the extract after pressure filtration. The filter holes of the conical fine filter cartridge 4 are finer than those on the filter screen 7, improving the filtration effect. The detachable design of the lower chamber 1 and the upper chamber 6 facilitates the cleaning of the conical fine filter cartridge 4, making it highly practical.
[0031] The filter screen 7 includes a screen body 701, filter holes 702, horizontal plates 703, telescopic rods 704, a support plate 705, and a top rod 706. The screen body 701 has filter holes 702. Two horizontal plates 703 are fixedly connected to the bottom of the screen body 701. Two telescopic rods 704 are symmetrically arranged on each of the two horizontal plates 703.
[0032] The inner rods of the telescopic rod 704 are all fixedly connected to the bearing plate 705. Multiple top rods 706 are fixedly connected to the bearing plate 705, and the top rods 706 are respectively set below the multiple filter holes 702.
[0033] The blocking mechanism 8 includes a mounting plate 801, a blocking block 802, a silicone layer 803, and fastening bolts 804. The blocking block 802 is fixedly connected to the mounting plate 801. The silicone layer 803 is wrapped around the outside of the silicone layer 803. Fastening bolts 804 are spirally connected to both sides of the mounting plate 801.
[0034] The silicone layer 803 is embedded in the discharge hole 602 on the upper box 6, and the mounting plate 801 is fixedly mounted on the side wall of the upper box 6 by fastening bolts 804.
[0035] The cleaning mechanism 9 includes a telescopic push rod 901 and a push plate 902. The two telescopic push rods 901 are symmetrically fixedly installed on the left side wall of the upper box 6. The inner rods of the two telescopic push rods 901 pass through the side wall of the upper box 6 and are fixedly connected to the push plate 902. The push plate 902 is embedded in the inner wall of the upper box 6.
[0036] The filter screen 7, clogging mechanism 8 and cleaning mechanism 9 provided on the upper housing 6 can automatically clean the filter residue, preventing the filter residue from clogging the filter holes 702 and affecting the filtration efficiency.
[0037] The filter press mechanism 10 includes a hydraulic column 1001 and a pressure plate 1002. The hydraulic column 1001 is fixedly installed on the top of the upper housing 6.

[0040] The working principle and usage process of this utility model are as follows: In specific use, the extract is added through the inlet 601. After a certain amount is added, the hydraulic column 1001 is activated, causing the inner column of the hydraulic column 1001 to extend and push the pressure plate 1002 downward in the upper housing 6 to filter the extract. The extract is filtered out through the filter holes 702 on the filter screen 7, while the medicinal residue is intercepted on the screen 701. The filtered extract then flows into the conical fine filter cylinder 4 through the receiving plate 101 for secondary filtration, avoiding residue residue. After one filtration cycle is completed, the hydraulic column 1001 rises again and then flows through the inlet 601 again. Add the extract for the next pressure filtration. After a certain period of use, remove the clogging mechanism 8 from the discharge hole 602. Then, activate the telescopic rod 704 to lift the support plate 705 upwards, so that the push rod 706 on the support plate 705 is inserted into the filter hole 702, thereby cleaning the filter hole 702 and preventing it from becoming clogged. Then, activate the two telescopic push rods 901. The push plate 902 is moved towards the discharge hole 602 by the extension and retraction of the inner rod of the telescopic push rod 901. During the movement, the medicine residue filtered by the filter screen 7 is pushed towards the discharge hole 602, so that the medicine residue is discharged through the discharge hole 602.
