[0002] In the process of producing collagen peptides, fish scales need to be decalcified, also known as deashing. The process involves first cleaning the fish scales, and then immersing them in a water-hydrochloric acid mixture for a specified time.

[0003] A Chinese patent application (or patent) with publication number CN220879730U discloses a stirring-type fish scale decalcification device, which includes a mixing tank and an aeration pipe.

Detailed Implementation

[0025] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5This utility model relates to a decalcification device for fish scale processing, comprising a decalcification tank 1, a filter assembly, a cleaning assembly, a circulation assembly, and a detection assembly. The cleaning assembly is located inside the decalcification tank 1, the circulation assembly is located on the right side of the decalcification tank 1, the filter assembly is located between the decalcification tank 1 and the circulation assembly, and the detection assembly is located in both the decalcification tank 1 and the circulation assembly. The circulation assembly includes a storage tank 3, in which a delivery pump 15 is installed. A return pipe 16 is fixedly connected to the output end of the delivery pump 15. A return hole 30 is opened on the side wall of the decalcification tank 1, and the other end of the return pipe 16 is fixedly installed in the return hole 30. Multiple waste liquid holes 4 are opened at the lower end of the inner wall of the decalcification tank 1, and a waste liquid chamber 5 is opened inside the decalcification tank 1. The multiple waste liquid holes 4 are all connected to the waste liquid chamber 5. A guide hole is opened on the side wall of the decalcification tank 1, and the guide hole is connected to the waste liquid chamber 5. A first pipe 6 is fixedly installed on the side wall of the decalcification tank 1 at the guide hole, and the other end of the first pipe 6... One end of the filter assembly is connected to the other end of the filter assembly. The other end of the filter assembly is provided with a second pipe 7, which is connected to the inside of the storage tank 3. A pressure valve 8 is installed on the first pipe 6. A pressure head 9 is provided at the upper end of the pressure valve 8. A motor slot is opened on the side wall of the decalcification box 1. A brake motor 24 is fixedly installed in the motor slot. The output shaft of the brake motor 24 is fixedly sleeved with a drive gear 25. A lifting groove 27 is opened on the inner wall of the decalcification box 1. A threaded rod 28 is rotatably installed on the inner wall of the lifting groove 27. A driven gear 26 is fixedly sleeved at the upper end of the threaded rod 28. The drive gear 25 and the driven gear 26 are meshed and connected. A threaded sleeve block 29 is threadedly sleeved on the threaded rod 28. A metal filter screen 12 is movably arranged inside the decalcification box 1. The side wall of the threaded sleeve block 29 is fixedly connected to one side of the material picking frame plate 11. A metal filter screen 12 is fixedly installed at the lower end of the threaded sleeve block 29. A pressure rod 13 is fixedly installed on the upper surface of the material picking frame plate 11.

[0028] Specifically: After the fish scales are cleaned by the cleaning components in the decalcification tank 1 or decalcified by a mixture of hydrochloric acid and water, the waste liquid from cleaning or decalcification enters the filter assembly through pipe 6 for filtration and purification. Then, it enters the storage tank 3 through pipe 7, where the purified waste liquid is recovered and stored for reuse. When water needs to be added to the decalcification tank 1, the purified waste liquid in the storage tank 3 can be returned to the decalcification tank 1 via the return pipe 16 by the transfer pump 15, achieving water circulation and effectively reducing water costs for fish scale cleaning and subsequent decalcification. After the fish scales have been cleaned and decalcified and the waste liquid has been discharged from the decalcification tank 1, the brake motor 24 can be started, causing the output shaft of the brake motor 24 to drive the drive gear 25 to rotate. The meshing of the drive gear 25 and the driven gear 26 causes the threaded rod 28 to rotate accordingly. Under the rotation of the threaded rod 28, the threaded sleeve 29 will move along... The thread of the threaded rod 28 moves vertically in the lifting groove 27, thereby driving the fish scales in the material picking frame plate 11 to rise so that the workers can collect the fish scales. The water attached to the surface of the fish scales can be drained on the metal filter screen 12. At the same time, during the process of the material picking frame plate 11 rising, it will drive the pressure rod 13, causing the pressure rod 13 to extend out of the decalcification box 1 and release the pressure on the pressure head 9. After the pressure head 9 is no longer under pressure, it rises, so that the pressure valve 8 in the first pipe 6 can be opened. At this time, the waste liquid in the waste liquid chamber 5 can be discharged from the decalcification box 1 through the first pipe 6.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the pressure rod 13 is a U-shaped column, with the other end of the pressure rod 13 extending out of the decalcification box 1 and perpendicularly corresponding to the pressure head 9; the side wall of the threaded sleeve 29 is slidably connected to the inner wall of the lifting groove 27, and the gear ratio of the driving gear 25 to the driven gear 26 is 1:2; the cleaning assembly includes four ultrasonic cleaners 20, and the detection assembly includes two hydrochloric acid concentration detectors 18 and a pH sensor 23. The inner wall of the decalcification box 1 is symmetrically provided with a first mounting slot 17 and two second mounting slots 19. The two hydrochloric acid concentration detectors 18 are respectively fixedly installed in the two first mounting slots 17, and the four ultrasonic cleaners 20 are respectively fixedly installed in the four second mounting slots 19. The pH sensor 23 is inserted into the side wall of the storage tank 3, with the detection end of the pH sensor 23 extending into the storage tank 3. The detection end of the hydrochloric acid concentration detector 18 and the sound wave emitting ends of the four ultrasonic cleaners 20 all face the inside of the decalcification box 1; the filter assembly includes a filter box 2 and three filter screens 14. The upper end face of the filter box 2 has three plate holes that match the filter screens 14, and the three filter screens 14 are slidably installed in the three plate holes respectively; a check valve 10 is fixedly installed on the side wall of the second pipe 7, and an injection port 21 is installed on the upper end face of the storage tank 3; a first waste liquid discharge hole is opened at the lower end of the inner wall of the storage tank 3, and a second waste liquid discharge hole 22 is opened on the side wall of the storage tank 3. The second waste liquid discharge hole 22 is connected to the first waste liquid discharge hole, and a solenoid valve is fixedly installed in the first waste liquid discharge hole; the side wall of the material picking frame plate 11 is slidably connected to the inner wall of the decalcification box 1, and the inner walls of the waste liquid chamber 5 and the second waste liquid discharge hole 22 are both inclined surfaces.

[0031] Specifically: by aligning the other end of the pressure rod 13 extending outside the decalcification box 1 perpendicularly to the pressure head 9, the pressure rod 13 can stably apply pressure to the upper end of the pressure head 9 as the material handling frame plate 11 rises and falls, thus ensuring stable opening and closing of the pressure valve 8; by sliding the side wall of the threaded sleeve 29 against the inner wall of the lifting groove 27, the threaded sleeve 29 can slide vertically along the inner wall of the lifting groove 27; by setting up detection components, two hydrochloric acid concentration detectors 18 can detect the hydrochloric acid content in the water inside the decalcification box 1, allowing control of the hydrochloric acid content in the water during fish scale cleaning; and the pH sensor 23 can perform water quality testing on the purified waste liquid in the storage tank 3. The ultrasonic cleaner 20 in the cleaning assembly is more effective at cleaning fish scales than conventional water agitation. A filtration assembly allows waste liquid to pass sequentially through three filter plates 14 in the filter tank 2. These filter plates 14 can be made of bio-cotton or activated carbon depending on the working conditions to purify the waste liquid. A check valve 10 effectively prevents backflow of purified waste liquid from the storage tank 3 into the second pipe 7. When the purified waste liquid in the storage tank 3 is determined by the detection assembly to be of poor quality and unusable, a solenoid valve can be opened, allowing the unusable waste liquid to be discharged to the outside through the first and second waste liquid discharge holes 22.

[0032] The working principle of this invention is as follows: After the fish scales are cleaned by the cleaning component or decalcified by a mixture of hydrochloric acid and water in the decalcification tank 1, the waste liquid from cleaning or decalcification enters the filter component through pipe 6 for filtration and purification. Then, it enters the storage tank 3 through pipe 7, where the purified waste liquid is recovered and stored for reuse. When water needs to be added to the decalcification tank 1, the purified waste liquid in the storage tank 3 can be returned to the decalcification tank 1 via the return pipe 16 by the transfer pump 15, achieving water circulation and effectively reducing the water cost for fish scale cleaning and subsequent decalcification.
