Detailed Description

The present invention is described in detail below with reference to the attached drawings:

as shown in fig. 1, 2 a medicinal membrane filter equipment, including shell body 1, shell body 1 is the stainless steel cylinder tubbiness that link up from top to bottom, cup joint the support 2 that two equal proportion scales in proper order in the shell body 1 and form the filtration of two-stage (also can be the multistage filter mechanism that more support 2 constitute in other embodiment), support 2 includes the spliced pole 23 that goes up ring 21, lower ring 22 and pass through welded connection at the six circumference equipartitions of going up ring 21 and lower ring 22, there is reverse osmosis membrane 3 through modes fixed mounting such as centre gripping or pasting between spliced pole 23.

In this embodiment, at least one of the filter cover 24 and the through-flow cover 25 is detachably disposed at the upper end and the lower end of the bracket 2 through a screw cap or a fixing bolt, in this embodiment, the filter cover 24 and the through-flow cover 25 are respectively connected to the two ends of the bracket 2 located at the outer side, the filter cover 24 is connected to one end of the bracket 2 located at the inner side and smaller, the other end is open, the through-flow column 251 of the through-flow cover 25 of the outer bracket 2 is made to extend downward into the through-flow column, the filter cover 24 includes an annular cover ring 241 and a reverse osmosis membrane 3 fixedly mounted in the cover ring 241, and the through-flow cover 25 includes the through-flow column 251 and an annular closed end cap.

In this embodiment, the through-flow column 251 includes a first through-flow section 253 located in the stent 2 and a second through-flow section 254 located outside the stent 2, a plurality of through-flow holes 255 are distributed on the surface of the first through-flow section 253, and the drug mixture solution that has passed through the reverse osmosis membrane 3 and completed filtration enters the second through-flow section 254 through the through-flow holes 255 and is transported outwards, or in reverse direction: the mixed liquid of the medicine entering from the second passing section 254 is filtered by contacting the reverse osmosis membrane 3 from the through hole 255 to the outside.

In this embodiment, the reverse osmosis membrane 3 is wound around the surface of the first through-flow section 253, thereby further improving the filtering effect. The coiled form can greatly increase the effective filtration area and provide a stable packing placement between the flow column 251 and the support 2.

In this embodiment, a draft tube 256 is connected to the second flow path 254 to transport the drug mixture.

In this embodiment, a connecting ridge 231 extending along the axial direction of the bracket 2 is disposed on one side of the connecting column 23 on the surface of the bracket 2, and a connecting groove 232 extending along the axial direction of the bracket 2 is disposed on one side of the connecting column 23 on the inner side of the bracket 2.
