[0026] This utility model embodiment provides a drug solution treatment and filtration device, such as... Figures 1-6 As shown, the pharmaceutical liquid treatment filtration device includes:

[0027] The filter cylinder 120 has a liquid inlet on the end cap 110 and a liquid outlet on the filter cylinder 120. The end cap 110 also has a threaded ring, and the inner wall of the filter cylinder 120 has threads. The end cap 110 is threadedly connected to the filter cylinder 120 through the threaded ring structure. The end cap 110 and the filter cylinder 120 are connected by a partition plate 130.

[0028] The partition plate 130 serves to block the direct connection between the end cap 110 and the filter cylinder 120. At the same time, the partition plate 130 is also provided with a channel, which is formed by a conduit 150 provided on the partition plate 130. The liquid medicine sent from the liquid inlet on the end cap 110 passes through the partition plate 130 through the conduit 150.

[0029] The filter element 200 includes a first assembly plate 210 and a second assembly plate 220. A connecting rod 230 is provided between the first assembly plate 210 and the second assembly plate 220, and a filter element 300 is also provided between the first assembly plate 210 and the second assembly plate 220.

[0030] The conduit 150 extends from the outer part of the end cap 110 to form a partition plate 130. The conduit 150 passes through the first assembly plate 210 and is inserted into the filter element 300. The liquid medicine inside the end cap 110 reaches the filter element 300 through the conduit 150 and then passes through the side wall of the filter element 300 to reach the filter cylinder 120.

[0031] The partition plate 130 is also provided with an assembly rod 140. The first assembly plate 210 and the second assembly plate 220 are both provided with an assembly hole 213 for the assembly rod 140 to pass through. The assembly rod 140 is provided with a limiting ring 141 and a bolt 142. The end face of the first assembly plate 210 away from the second assembly plate 220 is in contact with the limiting ring 141. The bolt 142 abuts against the end face of the second assembly plate 220 away from the first assembly plate 210.

[0032] In this embodiment, the filter element 200 and the filter cartridge 300 form an independent structure. They are assembled with the partition plate 130 by the assembly rod 140. During the assembly process, the independent structure formed by the filter element 200 and the filter cartridge 300 can be pre-assembled. When the filter structure is replaced or maintained, it can be directly assembled as a whole, reducing the process of disassembling and assembling the filter cartridge 300 one by one, improving the efficiency of the filter cartridge 300 replacement process of the liquid treatment filtration device, and reducing downtime.

[0033] In this application, the structure formed by the first assembly plate 210, the second assembly plate 220 and the connecting rod 230 can be quickly assembled with the help of the assembly rod 140, and the filter element 300 is pre-filled into the filter element 200, reducing the independent assembly of the filter element 300 and improving the replacement efficiency of the filter element 300.

[0034] As a preferred embodiment of this embodiment, the first assembly plate 210 is provided with a filter element mounting groove 211, and the second assembly plate 220 is provided with an embedding groove with the same structure as the filter element mounting groove 211. The two ends of the filter element 300 are respectively inserted into the filter element mounting groove 211 and the embedding groove.

[0035] In this embodiment, the bottom of the filter element mounting groove 211 is also provided with a through hole for accommodating the conduit 150, which extends into the interior of the filter element 300 through the through hole. The filter element 300 is a cylindrical structure with an open end. The filtrate flows from the inside of the filter element 300 through the side wall of the filter element 300 to the outside of the filter element 300. The filter element 300 is made of the same material as in the prior art. The number of filter elements 300 is not less than five sets, and the number of filter element mounting grooves 211 is the same as the number of filter elements 300.

[0036] In a preferred embodiment of this invention, one end of the connecting rod 230 is threadedly connected to the connecting seat 212 provided on the first assembly plate 210, and the end of the connecting rod 230 away from the first assembly plate 210 passes through the second assembly plate 220. The portion of the connecting rod 230 extending out of the second assembly plate 220 is threaded, and a fixing bolt is provided on the thread. The fixing bolt completes the connection between the connecting rod 230 and the second assembly plate 220 by screwing it in.

[0037] In this embodiment, the connecting rod 230 is mainly used to control the distance between the first assembly plate 210 and the second assembly plate 220 to fix the filter element 300. The number of connecting rods 230 is not less than three sets. Here, the filter element 200 and the filter element 300 are assembled before being filled into the filter cylinder 120.
