Description

Technical Field

[0001] The utility model relates to the technical field of drug treatment, in particular to a stainless - steel filter and a filter membrane. Background Art

[0002] The plate - frame filter is a common solid - liquid separation device, which consists of filter plates and filter frames. Multiple filter cloths or filter meshes are arranged on the filter plates to separate solid particles and liquid. During the filtration process, the liquid enters the filter frame through the pores on the filter plates, while the solid particles are intercepted by the filter cloths or filter meshes on the filter plates. In the pharmaceutical industry, the plate - frame filter is widely used in the following aspects: Drug purification: The plate - frame filter can remove suspended solids, microorganisms and other impurities in drugs, improving the purity and quality of drugs. Drug recovery and concentration: During the drug production process, some valuable components may need to be recovered or concentrated. The plate - frame filter can achieve drug recovery and concentration by selectively filtering out solvents or water molecules. Sterilization filtration: In the pharmaceutical process, many drugs need to be kept in a sterile state. The plate - frame filter can effectively remove microorganisms through a sterilization filter element to ensure the sterility of drugs. Clarification filtration: When there are visible solid particles or turbidity in drugs, clarification filtration is required to improve the transparency and appearance of drugs. The adjustable performance of the plate - frame filter makes it suitable for clarification filtration of different particulate matters. When in use, multiple filter membranes need to be stacked and squeezed by the plate - frame for filtration. After filtration, the filter membranes need to be removed one by one, which is time - consuming, and impurities will fall off during the transfer of the filter membranes.

[0042] Please refer to Figures 1-5 , the present utility model provides a technical solution: a stainless steel filter and a filter membrane, including:

[0043] Cross beams 2, the cross beams 2 are the load-bearing main bodies of the device, and there are two of them. The cross beams 2 are distributed left and right;

[0044] Clamping assemblies 5, and there are at least two of them. Because two sets of clamping assemblies 5 can clamp the filter membrane body 3 on both sides, the clamping assemblies 5 are installed on the outer wall of the cross beam 2 through sliding assemblies;

[0045] Connecting rod 6, both ends of the connecting rod 6 are connected to the two cross beams 2 respectively, so as to achieve the synchronization of the two cross beams 2.

[0046] In some embodiments, the clamping assembly 5 comprises:

[0047] A disbursement plate 52, the disbursement plate 52 is fixed to the side wall of the crossbeam 2;

[0048] A sliding groove 53, which is opened at one end of the disbursement plate 52 away from the crossbeam 2;

[0049] The clamping rod 51 has a relatively thin diameter and can be ignored when being clamped by the plate frame 1. There are two clamping rods 51, and a fixing assembly 7 is provided on the upper surface of the clamping rod 51. The clamping rod 51 is slidably engaged in the interior of the sliding groove 53 in the front and rear states. The clamping rod 51 slides in the interior of the sliding groove 53 to clamp the filter membrane 3.

[0050] In some embodiments, the sliding assembly 4 can ensure the smooth movement of the clamping assembly, and the sliding assembly 4 includes:

[0051] A wheel frame 41, which is located on the upper part of the crossbeam 2;

[0052] A roller 42, the roller 42 is movably mounted inside the wheel frame 41;

[0053] The slide rail 43 is opened on the upper surface of the beam 2, and the roller 42 is located inside the slide rail 43. When the clamping assembly 5 moves, the wheel frame 41 is pushed by the expenditure plate 52 to drive the roller 42 to slide inside the slide rail 43, thereby realizing movement on the beam 2.

[0054] In some embodiments, the fixing assembly 7 comprises:

[0055] There are two cartridges 71, which are fixedly connected to the upper surfaces of the two clamping rods 51 respectively; a connecting frame 73, which is arranged above the cartridge 71, and the bottoms of both ends of the connecting frame 73 are fixedly connected with clamping rods 72, which are clamped into the interior of the cartridge 71, so as to fix the clamping state of the two clamping rods 51 on the filter membrane 3.

[0056] In some embodiments, the two wheel frames 41 are connected via a linkage rod 11 , so that the synchronization of the movement of the clamping assembly 5 can be ensured.

[0057] In some embodiments, the top outer wall of the clamping rod 51 is symmetrically fixed to the limit plate 10 , and the limit plate 10 is in contact with the dispensing plate 52 to ensure that the clamping rod 51 will not be separated from the inside of the sliding groove 53 .

[0058] In some embodiments, the plate frame 1 is included, and the cross beam 2 is mounted on the upper part of the plate frame 1. The plate frame 1 is a plate frame in the plate frame filter, and the number of the plate frame 1 can be multiple. Figure 1 Two of them are listed as examples to illustrate the state of the device in a plate-and-frame filter, that is, the clamping assembly is between two plate frames 1 .

[0059] Please refer to Figures 5-7 , the present utility model provides a technical solution: a filter membrane, comprising:

[0060] A filter membrane body 3, which is used for filtering impurities. A covering section 9 is integrally formed on the filter membrane body 3 through a connecting section 8. When the covering section 9 is unfolded, it presses on the surface of the filter membrane body 3 to prevent impurities from falling off when the filter membrane 3 body is taken out. And the covering section 9 is generally in a curled state, which does not affect the use of the filter membrane body 3. Refer to Figure 5 as the initial state, and Figure 6 is the state where the covering section 9 extends and covers the filter membrane body 3, Figure 7 is the state where the covering section 9 is unfolded but does not cover the filter membrane body 3.

[0061] In some embodiments, the area of the covering section 9 is larger than that of the filter membrane body 3 to ensure complete coverage of the filter membrane body 3.

[0062] In some embodiments, a liquid non-drying adhesive is applied to the side of the covering section 9 close to the filter membrane body 3 to ensure tight fitting with the filter membrane body 3.

[0063] Working principle: Place the filter membrane body 3 between the clamping rods 51. The clamping rods 51 slide inside the sliding groove 53 and then clamp the filter membrane 3 body. Hold the connecting frame 73 and drive the clamping rod 72 to snap into the inside of the cartridge 71, which can fix the clamping state of the two clamping rods 51 on the filter membrane 3. When the plate frame 1 clamps the filter membrane body 3, since the wheel frame 41 in the sliding assembly 4 drives the roller 42 to slide inside the slide rail 43, it can move on the cross beam 2, and one pushes another to closely fit for filtration preparation. After filtration, hold the cross beam 2 to take out all the filter membrane bodies 3. When the covering section 9 is unfolded, it presses on the surface of the filter membrane body 3 to prevent impurities from falling off when the filter membrane body 3 is taken out.

[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
