Description

Technical Field

[0001] This utility model relates to the field of gelatin production technology, specifically to a multi-stage fine filtration device for colloid purification. Background Technology

[0002] Gelatin is a macromolecular hydrophilic colloid, a product of partial hydrolysis of collagen. It is a colorless to pale yellow solid, occurring in powder, flake, or block form. It is glossy, odorless, and tasteless. Based on its properties and uses, it can be classified into photographic gelatin, edible gelatin, and industrial gelatin. The quality requirements for gelatin vary depending on its application. When used as a binder, adhesive strength is the primary requirement. When used in photography, food, and pharmaceutical fields, product purity is emphasized, necessitating the use of specialized gelatin filters during the gelatin production process.

[0003] Existing filtration devices for gelatin purification require timely cleaning after filtration because gelatin is a hydrophilic colloid with viscosity. If not cleaned promptly, the gelatin solution will cool and increase in viscosity, forming a gel-like substance. Additionally, gelatin solution residue on the filter screen may also adhere to it after cooling. Current cleaning methods typically involve hot water rinsing, which is inconvenient due to the limited internal space. Filter screen cleaning often requires disassembly, increasing workload and frequency, thus reducing practicality. Therefore, we propose a multi-stage fine filtration device for colloid purification to address these issues. Utility Model Content

[0013] Compared with the prior art, this utility model provides a multi-stage fine filtration device for colloid purification, which has the following beneficial effects:

[0014] 1. This multi-stage fine filtration device for colloid purification uses a second motor and connecting rod to rotate the filter barrel.

[0025] 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.

[0026] Please see Figures 1-5This utility model provides a technical solution: a multi-stage fine filtration device for colloid purification, including a mounting plate 1, a mounting frame 2 fixedly connected to the upper surface of the mounting plate 1, a filter barrel 3 arranged on the lower side of the mounting frame 2, three filter components 4 arranged inside the filter barrel 3, a rotating rod 5 rotatably connected inside the filter barrel 3, a stirring rod 6 fixedly connected to the outer surface of the rotating rod 5, a first water passage chamber 7 opened inside the rotating rod 5, a second water passage chamber 8 opened inside the stirring rod 6, the first water passage chamber 7 and the second water passage chamber 8 being connected, a nozzle 9 embedded inside the stirring rod 6, the nozzle 9 being connected to the second water passage chamber 8, a water injection component arranged at the lower end of the rotating rod 5, and a flipping component arranged outside the mounting frame 2.

[0027] The filter assembly 4 includes an annular frame 401, which is fixedly installed on the inner wall of the filter barrel 3. A support plate 402 is fixedly connected inside the annular frame 401. The support plate 402 is rotatably sleeved on the outside of the rotating rod 5. A filter screen 403 is provided between the support plate 402 and the inner wall of the annular frame 401.

[0028] In the above embodiments, the three filter components 4 have different filtration accuracies, thereby achieving multi-stage filtration of gelatin.

[0029] The water injection assembly includes a connecting pipe 10, which is fixedly connected to the lower end of the rotating rod 5. The lower end of the connecting pipe 10 rotates through the lower surface of the filter bucket 3.

[0030] A water inlet pipe 12 is provided on the outside of the connecting pipe 10, and a rotating flange 11 is rotatably connected between the water inlet pipe 12 and the connecting pipe 10.

[0031] A scraper 13 is fixedly connected to the end of the stirring rod 6 away from the rotating rod 5. The scraper 13 is in contact with the inner wall of the filter barrel 3. Both sides of the scraper 13 are provided with inclined surfaces 1301. By setting the inclined surfaces 1301, the scraper 13 can effectively improve the removal efficiency of gelatin on the inner wall of the filter barrel 3.

[0032] The bottom plate of the filter barrel 3 has a cavity 14. A sprocket 16 is fixedly sleeved at one end of the connecting pipe 10 inside the cavity 14. A support shaft 15 is rotatably connected inside the cavity 14. A sprocket 16 is also fixedly sleeved on the outside of the support shaft 15. A chain 17 is meshed with the outside of the two sprockets 16.

[0033] A first motor 18 is fixedly connected to the lower surface of the filter barrel 3. The output shaft of the first motor 18 rotates and penetrates into the interior of the filter barrel 3. The output shaft of the first motor 18 is fixedly connected to the support shaft 15 through a coupling.

[0034] The flipping assembly includes a second motor 19, which is fixedly connected to the outer surface of the mounting frame 2. Two connecting rods 20 are fixedly connected to the outer surface of the filter barrel 3. The filter barrel 3 is rotatably connected between the two vertical plates of the mounting frame 2 through the connecting rods 20. The output shaft of the second motor 19 rotates through the interior of the mounting frame 2. The output shaft of the second motor 19 is fixedly connected to the connecting rods 20 through a coupling.

[0035] Among them, the first motor 18 and the second motor 19 are matched with power supply, wires, controller and microcomputer and other structures. Since they are not the main structures, they will not be described in detail in this article. At the same time, the filter barrel 3 can only rotate 180 degrees when it is flipped, so as to effectively avoid the wires from getting tangled.

[0036] Working principle:

[0037] When using this multi-stage fine filtration device for colloid purification, turning on the switch of the first motor 18 causes the output shaft of the first motor 18 to rotate, which in turn drives the support shaft 15. The rotation of the support shaft 15, along with the transmission of the sprocket 16 and chain 17, drives the rotation of the connecting pipe 10. Since the connecting pipe 10 and the inlet pipe 12 are connected by a rotating flange 11, and the inlet pipe 12 is restricted by external conveying equipment, the rotation of the connecting pipe 10 does not affect the rotation of the inlet pipe 12. The rotation of the connecting pipe 10 then drives the rotation of the rotating rod 5, which in turn drives the rotation of the stirring rod 6, which in turn drives the rotation of the scraper 13. The gelatin to be filtered is then added to the inside of the filter tank 3. The three filtration components 4 then filter the gelatin step by step, and the rotation of the stirring rod 6 agitates the gelatin, thus maintaining the colloidal solution in a uniform suspension state, improving the filtration effect and efficiency. After filtration, the gelatin is discharged from the outlet outside the filter tank 3.

[0038] When the filtration is complete and the filter bucket 3 needs to be cleaned, turn on the switch of the second motor 19. The rotation of the output shaft of the second motor 19 will drive the rotation of the connecting rod 20, thereby causing the filter bucket 3 to flip. Subsequently, water is injected and pressurized into the connecting pipe 10 through the external water injection component. At this time, the cleaning water will enter the interior of the second water injection chamber 8 through the first water chamber 7 and be sprayed out through the nozzle 9. This will rinse the filter component 4, and the scraper 13 will scrape the inner wall of the filter bucket 3, thus cleaning the filter bucket 3. At the same time, the staff can place a collection device on the lower side of the filter bucket 3 to facilitate the collection of cleaning water and impurities washed out.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
