Description

Technical Field

[0001] This utility model relates to the field of affinity membrane technology, and in particular to an affinity membrane treatment frame that is easy to maintain. Background Technology

[0002] Affinity membranes are filter membranes modified with affinity ligands. Affinity membrane separation is a separation method that uses affinity membranes as affinity adsorption media to purify target products. It is a variation of affinity chromatography and is also known as membrane affinity chromatography. Affinity membranes are generally used for protein separation, nucleic acid extraction and purification, and enzyme separation and immobilization.

[0003] Before using affinity membranes to separate proteins, they need to be fixed on a membrane holder, and then the membrane holder is fixed in the protein separation cell with bolts to prevent the affinity membrane from deforming or curling during dynamic adsorption. In the existing technology, the affinity membrane is fixed to the membrane holder by welding or clamping, which makes the subsequent disassembly and assembly of the affinity membrane more complicated and inconvenient for later maintenance or cleaning.

[0004] To address these issues, a membrane frame with an affinity membrane treatment that is easy to maintain is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an affinity membrane treatment frame that is easy to maintain, aiming to improve the problem of complicated disassembly when maintaining affinity membranes in the prior art.

The right side of the fixing block contacts the left side of the T-shaped slider. The rear side of the fixing block is threadedly connected to the inside of the fixing base via a bolt.

[0010] As a further description of the above technical solution:

[0011] The limiting assembly includes a limiting rod, which is movably connected to the surface of the support rod via a shaft. The surface of the limiting rod contacts the inner wall of the limiting groove, and the side of the limiting rod away from the shaft is threadedly connected to the surface of the mounting plate via a bolt.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1-7 This utility model provides an embodiment of an affinity membrane processing frame that is easy to maintain. It includes a fixed base 1, which is bolted to the inside of a protein separation tank. A base 2 is provided on the top of the fixed base 1, and support rods 3 are fixedly connected to the four corners of the top of the base 2. Handles 19 are fixedly connected to the top of the support rods 3, facilitating the movement of the membrane frame by workers. A mounting plate 4 is provided on the top of the base 2, and a reinforcing plate 20 is fixedly connected to the inner side of the mounting plate 4 to prevent breakage at the connection between the mounting plate 4 and the support rods 3. The outer side of the reinforcing plate 20 is fixedly connected to the surface of the support rods 3. The front and rear sides of the mounting plate 4 are fixedly connected to the surface of the support rods 3. Multiple fixing grooves 5 are provided inside the mounting plate 4, and support blocks 22 are fixedly connected to the inner walls of the fixing grooves 5 to limit the clamping blocks 7, preventing excessive rotation of the clamping blocks 7 and ensuring proper closure for fixing the affinity membrane 8. A movable plate 6 is slidably connected inside the fixing grooves 5. A clamping block 7 is movably connected to the top of the 6 via a shaft. A rubber pad 21 is fixedly connected to the surface of the clamping block 7. The rubber pad 21 reduces wear when the clamping block 7 is in long-term contact with the affinity film 8, thus extending the service life of the clamping block 7. An affinity film 8 is provided on the inner side of the clamping block 7. Guide plates 9 are fixedly connected to the front and rear sides of the fixing groove 5. A fixing plate 10 is engaged with the front side of the moving plate 6. The fixing plate 10 is slidably connected inside the mounting plate 4. A retaining spring 11 is fixedly connected to the front side of the fixing plate 10. The rear side is fixedly connected to the inner wall of the mounting plate 4. The bottom of the movable plate 6 is provided with a push block 12. The surfaces of the movable plate 6 and the push block 12 are both covered with sealing gaskets 18. By setting the sealing gaskets 18, the gap between the movable plate 6 and the push plate and the mounting plate 4 is sealed to prevent liquid from entering the interior of the mounting plate 4 and affecting the normal operation of the internal parts. The sealing gaskets 18 are fixedly connected to the surface of the mounting plate 4. The side of the push block 12 away from the movable plate 6 extends to the outside of the mounting plate 4. The surface of the push block 12 is provided with a limiting groove 13.

[0036] Reference Figure 2-6The surface of the fixed base 1 is provided with a fixing component, which includes a slide groove 14. The slide groove 14 is opened on the front and rear sides of the fixed base 1. A T-shaped slider 15 is slidably connected inside the slide groove 14. The top of the T-shaped slider 15 is fixedly connected to the bottom of the base 2. A fixing block 16 is movably connected inside the fixed base 1 through a shaft. The right side of the fixing block 16 contacts the left side of the T-shaped slider 15. The rear side of the fixing block 16 is threadedly connected to the inside of the fixed base 1 by a bolt. First, rotate the bolt to release the limitation on the fixing block 16. Then, rotate the fixing block 16 around the shaft to release the fixation on the T-shaped slider 15 and the base 2. Then, move the base 2 to the left to move the T-shaped slider 15 out of the slide groove 14, and the base 2 can be removed, thereby achieving the effect of quickly removing the base 2 from the protein separation tank.

[0037] Reference Figure 1-5 The surface of the mounting plate 4 is provided with a limiting component, which includes a limiting rod 17. The limiting rod 17 is movably connected to the surface of the support rod 3 via a shaft. The surface of the limiting rod 17 contacts the inner wall of the limiting groove 13. The side of the limiting rod 17 away from the shaft is connected to the surface of the mounting plate 4 by a bolt thread. After rotating the bolt to release the fixing of the limiting rod 17, the limiting rod 17 is rotated around the shaft to move it out of the limiting groove 13, thereby pushing the block 12 to its limit.

[0038] Working principle: When the affinity membrane 8 needs to be inspected, first use a tool to remove the bolts on the surface of the fixing block 16. Then, rotate the fixing block 16 around the shaft to remove the limit on the T-shaped slider 15. Move the base plate to the left to remove the T-shaped slider 15 from the slide groove 14, and the base 2 can be removed from the fixing seat 1, thus achieving the effect of quickly removing the base 2 from the protein separation cell. When removing the affinity membrane 8, first use a tool to remove the bolts on the surface of the limiting rod 17. Rotate the limiting rod 17 around the shaft to move it out of the limiting groove 13. The pusher block 12 is released, and then the pusher block 12 is pressed to move the moving plate 6 upward. The moving plate 6 moves upward and causes the clamping block 7 to disengage from the guide plate 9, so that the clamping block 7 opens outward around the shaft to release the fixation of the affinity membrane 8. At the same time, the moving plate 6 moves upward and pushes the fixing plate 10 to squeeze and press the spring sheet 11 to make it elastically compressed, so that the affinity membrane 8 can be removed. The above operation can be reversed to reinstall the affinity membrane 8 inside the protein separation cell, thereby achieving the effect of quickly disassembling the affinity membrane 8 and facilitating its maintenance.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
