Problems solved by technology

[0002] In the purification and extraction of biopharmaceuticals, it is generally necessary to go through steps such as filtering the extract, concentrating, and ion-exchange chromatography. The filtering devices of the prior art not only have a small filtering area, which will cause long filtering time and affect the filtering efficiency. It is easy to be clogged during filtration, thereby affecting the filtering effect, and the applicability is limited. The Chinese patent (notification number CN207805207U) discloses a candle end face cutting device equipped with drilling candle wick holes. Although it can solve the problem to a certain extent, However, due to the imperfect design of the filtrate structure and its collection structure, the filtrate effect is poor, and the safety of the device is not high

Embodiment 1

[0020] See figure 1 , image 3 In the embodiment of the present invention, a pipeline-guided multi-stage filter device includes a horizontally arranged support installation box 4, and the upper half of the inner part of the support installation box 4 is provided with a multi-stage pipeline filter structure and supports The two ends of the lower side of the installation box 4 are symmetrically provided with support installation columns 17, and the lower ends of the support installation columns 17 are provided with anti-skid pads. The multi-stage pipeline filtering structure includes the upper half of the support installation box 4 horizontally and longitudinally at equal intervals. The three-component filter tube 12, the diameter of the sub-filter tube 12 decreases sequentially from back to front. The right end of the last two-component filter tube 12 and the left end of the first two-component filter tube 12 are connected by a U-shaped variable diameter guide tube 1 , The two e...

Embodiment 2

[0022] Refer to figure 2 On the basis of the first embodiment, the electronically controlled overflow structure includes a diversion mounting frame 20 vertically arranged at one end of the filtering tube 12, and a one-way overflow valve is horizontally embedded in the middle position of the diversion mounting frame 20 21. The outer side of the one-way overflow valve 21 cooperates with the diversion mounting frame 20 to provide a rotating butterfly valve 18, and the upper end of the diversion mounting frame 20 cooperates with the rotating butterfly valve 18 to extend and is provided with a rotation control dial 19, when the pressure is too high, it will pass The one-way overflow valve 21 overflows and diverts the flow, so that the pressure intensity in the device is stable and the safety of the device is protected.

Abstract

The invention relates to the field of biological pharmacy, in particular to a pipeline diversion type multi-stage filtration device. The device comprises a supporting and mounting box arranged horizontally; a multi-stage pipeline filtration structure is arranged at the upper-half section of the inside of the supporting and mounting box; supporting and mounting columns are symmetrically arranged attwo ends of the lower side of the supporting and mounting box; non-slip pads are arranged at lower ends of the supporting and mounting columns; the multi-stage pipeline filtration structure comprisesthree filtration ducts arranged horizontally and longitudinally at equal intervals at the upper-half section of the supporting and mounting box; and hand valves and electrically-controlled overflow structures are arranged at two ends of each filtration duct. Multi-stage differential filtration is realized through filtrate diversion by the aid of the multiple filtration ducts, and opening and closing are controlled automatically according to the filtration precision requirement, so that the filtration efficiency is high, filtration selectivity is high, and collection is convenient; the horizontal structure is adopted, so that the occupied area is small; and overflowing diversion is realized through one-way overflow valves when the pressure is too high, so that the pressure intensity insidethe device is stable, and the safety of the device is protected.

Description

Technical field [0001] The invention relates to the field of biopharmaceuticals, in particular to a separation filter device for pharmaceutical extracts. Background technique [0002] In the purification and extraction of biopharmaceuticals, it is generally necessary to go through the steps of filtering the extract, concentration, and ion exchange chromatography. The prior art filtering device not only has a small filtering area, it will cause a long filtering time and affect the efficiency of filtering. Clogging is easy to occur during filtration, which affects the filtration effect, and its applicability is limited. The Chinese patent (Announcement No. CN207805207U) discloses a candle end face cutting device with a drilled candle core hole. Although it can solve the problem to a certain extent, However, due to the imperfect design of the filtrate structure and its collection structure, the filtrate effect is poor and the safety of the device is not high. [0003] In order to sol...
