Technical Field

[0001] The utility model relates to the technical field of heparin sodium preparation, in particular to a filtering device for heparin sodium preparation. Background Technique

[0002] Heparin sodium is the sodium salt of sulfated glucosaminoglycan extracted from the intestinal mucosa of pigs or cows. It belongs to the category of mucopolysaccharides. During the production and processing of heparin sodium, the enzymatically or salted materials usually need to be filtered to further obtain the heparin sodium extract. Heparin sodium filtering devices generally use filter meshes or mesh plates to screen the filtrate in the mixture, or are placed inside a filtering box for static filtration.

[0003] After retrieval, a Chinese patent discloses a filtering device for heparin sodium production, with its authorization announcement number (CN212680258U), including a filtering tank body, a filtering core tube, a feeding pipe body, a pressing air cylinder, a discharging pipe body, a discharging pipe body, and fixed legs.

[0004] During the filtering process of the heparin sodium extract by this device, the pressing air cylinder uses a piston to filter the extract through a filter tube with filter holes. Although a lid is added to the filtering tank body, in actual operation, after the filtering is completed, the inside of the entire filtering tank body needs to be cleaned for the next use. Therefore, it is necessary for workers to remove the lid connected to the pressing air cylinder and then clean the inside, which is rather troublesome, thus increasing the labor and time costs.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 - 4As shown, in this embodiment, a filtering device for preparing sodium heparin includes a bottom plate 1, a bracket 10 is fixedly connected to the top of the bottom plate 1, a lifting assembly is arranged on the top of the bracket 10, a fixing plate 9 is fixedly connected to the bottom of the lifting assembly, a first cylinder 17 is fixedly installed on the top of the fixing plate 9, one end of the movable rod of the first cylinder 17 is fixedly connected to the extrusion plate 14, a filter box 4 is fixedly connected to the top of the bottom plate 1, a mounting plate 12 is slidably connected to the inside of the filter box 4, a filter screen 6 is arranged inside the mounting plate 12, a fixing block 5 is fixedly connected to one side of the filter box 4, a slide groove 23 is opened inside the fixing block 5, a limiting assembly is arranged inside the slide groove 23, a feed pipe 3 is fixedly connected to one side of the filter box 4, and a discharge pipe 15 is fixedly connected to one side of the filter box 4 and located at the bottom of the filter screen 6.

[0023] First, the sodium heparin extract is input into the filter box 4 through the feed pipe 3 on one side of the filter box 4, and then the first cylinder 17 movable rod is used to move and drive the squeezing plate 14 in the filter box 4 to squeeze the sodium heparin extract entering the filter box 4, which can cooperate with the filter screen 6 in the filter box 4 to improve the filtration efficiency. After the filtration is completed, the liquid can be discharged through the discharge pipe 15. When it is necessary to clean the internal components of the filter box 4, it is only necessary to start the lifting assembly to drive the fixed plate 9 to detach from the top of the filter box 4. The bottom of the fixed plate 9 is provided with a sealing cover, which fits with the top of the filter box 4, and then drive the squeezing plate 14 to move out from the inside of the filter box 4, so that it can be cleaned more conveniently. The hygiene inside the filter box 4 is improved, thus avoiding the need to clean the entire filter tank body after filtering for the next use. Therefore, it is necessary to manually remove the cover connected to the extrusion cylinder, and then perform internal cleaning, which is troublesome, thereby increasing the cost of manpower and time. Finally, when the filter 6 needs to be replaced and cleaned, the fixing of the mounting plate 12 can be released by toggling the limit assembly, and the handle is pulled to drive the filter 6 to be pulled out from the inside of the filter box 4 for replacement. Then, when installing the filter 6, it is only necessary to insert the mounting plate 12 into the inside of the filter box 4, and the position of the mounting plate 12 can be automatically fixed by the limit assembly, thereby increasing the convenience of installation.

[0024] like Figures 1 - 4As shown, the lifting assembly includes two vertical plates 18, which are fixedly connected to the top of the bracket 10, and a sliding rod 16 is fixedly connected between the two vertical plates 18. A displacement block 20 is movably sleeved on the outer side of the sliding rod 16. A second cylinder 19 is fixedly installed on the top of one of the vertical plates 18, and one end of the movable rod of the second cylinder 19 is fixedly connected to one side of the displacement block 20. The lifting assembly also includes two displacement plates 8, which are slidably connected to the top of the bracket 10, and the bottoms of the two displacement plates 8 are fixedly connected to the top of the fixed plate 9. A displacement groove 2 is penetrated through the outer side of the two displacement plates 8, and a displacement rod 7 is slidably connected to the inside of the displacement groove 2, and one end of the displacement rod 7 is fixedly connected to one side of the displacement block 20.

[0025] When moving the fixed plate 9, the movable rod is moved by starting the second cylinder 19 to drive the displacement block 20 to move on the outside of the sliding rod 16 and drive the displacement rod 7 to slide inside the displacement groove 2. Then the movement of the displacement block 20 is guided by the sliding rod 16, and then the displacement rod 7 moves to drive the displacement plate 8 to move inside the bracket 10, so that the position of the fixed plate 9 can be better adjusted.

[0026] like Figures 1 - 4 As shown, the limit assembly includes a slider 25, which is slidably connected to the inside of the slide groove 23, and a spring 24 is fixedly connected between one side of the slider 25 and the inner wall of the slide groove 23. The limit assembly also includes a clamping block 11, which is slidably connected to the inside of the fixed block 5, and one end of the clamping block 11 is fixedly connected to one side of the slider 25. A clamping groove 13 is provided on the top of the mounting plate 12, and one end of the clamping block 11 extends to the inside of the clamping groove 13. A limit groove 21 is penetrated through one side of the fixed block 5, and a lever 22 is slidably connected to the inside of the limit groove 21, and one end of the lever 22 is fixedly connected to one side of the slider 25.

[0027] When the restriction on the mounting plate 12 is released, the slider 25 is driven to move by toggling the toggle lever 22 and the block 11 is disengaged from the inside of the slot 13, so that the fixing of the mounting plate 12 can be released, so that the filter screen 6 can be replaced better. Then, when installing the filter screen 6, the mounting plate 12 is inserted into the interior of the filter box 4, and one side of the mounting plate 12 contacts the inclined surface of the block 11, thereby driving the block 11 to move and driving the slider 25 to compress the spring 24. Then, when the slot 13 at the top of the mounting plate 12 moves to the bottom of the block 11, the block 11 is automatically driven into the inside of the slot 13 under the reaction force of the spring 24, thereby completing the fixing of the mounting plate 12.

[0028] The utility model provides a filtering device for preparing sodium heparin, and the specific working principle is as follows: first, the sodium heparin extract is input into the filter box 4 through the feed pipe 3 on one side of the filter box 4, and then the first cylinder 17 movable rod is used to move and drive the extrusion plate 14 in the filter box 4 to extrude the sodium heparin extract entering the filter box 4, which can cooperate with the filter screen 6 in the filter box 4 to improve the filtration efficiency. After the filtration is completed, the liquid can be discharged through the discharge pipe 15. When it is necessary to clean the internal components of the filter box 4, it is only necessary to start the second cylinder 19 movable rod to move and drive the displacement block 20 to move on the outside of the slide rod 16 and drive the displacement rod 7 to slide inside the displacement groove 2, and then the movement of the displacement block 20 is guided by the slide rod 16, and then the displacement rod 7 moves and drives the displacement plate 8 inside the bracket 10. The filter screen 6 can be replaced by moving the slider 25 and the block 11 can be disengaged from the slot 13 by toggling the lever 22. The fixing of the mounting plate 12 can be released, so that the filter screen 6 can be replaced better. Next, when installing the filter screen 6, the mounting plate 12 is inserted into the interior of the filter box 4. One side of the mounting plate 12 contacts the inclined surface of the block 11, thereby driving the block 11 to move and the slider 25 to compress the spring 24. Then, when the slot 13 at the top of the mounting plate 12 moves to the bottom of the block 11, the block 11 is automatically driven into the slot 13 by the reaction force of the spring 24, thereby completing the fixing of the mounting plate 12.
