Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of fish scale collagen production technology, specifically to a fish scale collagen extraction and liming device. Background Technology
[0002] Collagen, as an important biopolymer, is widely used in food, medicine, cosmetics, and biomaterials due to its excellent biocompatibility, biodegradability, and low immunogenicity. Fish scales are one of the main byproducts of aquatic product processing and are rich in high-quality type I collagen. Their sources are abundant and inexpensive, making collagen extraction from fish scales an important development direction for this industry.
[0003] In the traditional extraction process of fish scale collagen, "liming" is a crucial pretreatment step. The main purpose of this step is to dissolve and remove impurities such as non-collagen proteins, lipids, and pigments from the fish scales, and to fully swell the fish scale tissue, creating favorable conditions for subsequent acid or enzymatic extraction of high-purity collagen.
[0004] In the prior art with application number CN201621428804.2, when liming, fish scales need to be placed on multiple placement partitions first, and then the support sleeves connected to the placement partitions are sequentially placed on the hollow shaft and covered with a cover plate. The operation process is complicated, prone to errors, and the overall work efficiency is not high. Utility Model Content

The top is an open structure and is detachably fitted with a top cover that also has multiple filter holes. A top-open ash-soaking tank is located directly below the processing basket.
[0007] Furthermore, the lifting mechanism includes multiple vertical guide rods, which are evenly distributed and fixed to the top edge of the lifting plate and slide in cooperation with the corresponding guide holes on the support bracket. A cylinder is installed on the top of the support bracket, and the piston rod of the cylinder passes vertically downward through the support bracket and is fixedly connected to the top of a protective bracket. The protective bracket is fixedly installed on the top of the lifting plate, and the drive motor is located inside the protective bracket.
[0008] Furthermore, bearing sleeves are fixedly installed on both opposite side walls of the U-shaped support frame. The two bearing sleeves are respectively rotatably engaged with two rotating shafts symmetrically fixed to the outer wall of the processing basket. The bearing sleeves are provided with a first positioning hole and a second positioning hole that are spaced 180° apart. The rotating shafts are provided with a third positioning hole. The third positioning hole is aligned with the first positioning hole or the second positioning hole and is locked by a positioning bolt.
[0009] Furthermore, a handle is installed on the top of the top cover, and an external thread is provided on its outer periphery. The inner wall of the opening end of the processing basket is provided with an internal thread that mates with the external thread.
[0010] Furthermore, it also includes a delivery pump, the inlet of which is connected to a first delivery pipe with a valve, and the outlet of which is connected to a second delivery pipe with a valve. The inlet end of the first delivery pipe extends to the bottom of the immersion tank, and the outlet end of the second delivery pipe extends to the top of a filter tank.

The inlet end of the third conveying pipe extends to the bottom of the filter tank, and the outlet end of the fourth conveying pipe extends to the top of the ash-soaking tank.
[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: During operation, fish scales are loaded into the predetermined capacity from the top of the treatment basket. After the top cover is installed, the lifting plate is lowered by the lifting mechanism so that the treatment basket is immersed in the ash liquid in the ash soaking tank. The ash soaking treatment of a large number of fish scales can be completed at one time. The operation is simple and efficient.
[0013] Once the predetermined time has elapsed, the lifting mechanism is used to raise the processing basket to a position above the liquid surface and inside the tank. The drive motor is then started, causing the U-shaped support frame and processing basket to rotate. Centrifugal force is used to remove residual moisture from the fish scales, thereby improving the subsequent drying efficiency.
[0014] The two bearing sleeves are respectively rotated and fitted with two rotating shafts that are symmetrically fixed to the outer wall of the treatment basket. When the third positioning hole is aligned and fixed with the second positioning hole, the treatment basket is in the open downward position, which makes it easy to discharge the fish scales after ash soaking.

[0021] See attached document Figure 1-5 A fish scale collagen extraction and liming device includes a support bracket 1, a lifting mechanism 2 on the support bracket 1, the lifting mechanism 2 being connected to a lifting plate 3 and driving it to move vertically, a drive motor 4 being installed above the lifting plate 3, and a processing basket 6 being connected below it via a U-shaped support frame 5, the output shaft of the drive motor 4 vertically penetrating the lifting plate 3 and being fixedly connected to the top of the U-shaped support frame 5; the processing basket 6 has multiple filter holes distributed on its periphery and bottom, an open structure at the top, and a top cover 7 with multiple filter holes that is detachably installed, and an liming tank 8 with an open top is provided directly below the processing basket 6.
[0022] In this embodiment, fish scales are loaded into the processing basket 6 to a predetermined capacity from the top. After the top cover 7 is installed, the lifting plate 3 is driven down by the lifting mechanism 2, so that the processing basket 6 is immersed in the ash liquid in the ash soaking tank 8. After the predetermined ash soaking time is reached, the lifting mechanism 2 is operated to lift the processing basket 6 to a position that is above the liquid surface but still in the ash soaking tank 8. At this time, the drive motor 4 is started, which drives the U-shaped support frame 5 and the processing basket 6 to rotate together. The centrifugal force removes a large amount of residual moisture from the fish scales, thereby improving the subsequent drying efficiency.
[0023] In the above embodiments, during the process of the lifting mechanism 2 driving the lifting plate 3 to rise and fall, the drive motor 4 is always located above the ash liquid surface in the ash soaking tank 8, so as not to affect it.
[0024] The lifting mechanism 2 includes multiple vertical guide rods 201, which are evenly distributed and fixed to the top edge of the lifting plate 3 and slide in cooperation with the corresponding guide holes on the support bracket 1. A cylinder 202 is installed on the top of the support bracket 1. The piston rod of the cylinder 202 passes vertically downward through the support bracket 1 and is fixedly connected to the top of a protective bracket 203. The protective bracket 203 is fixedly installed on the top of the lifting plate 3, and the drive motor 4 is located inside the protective bracket 203.
[0025] In this embodiment, the protective bracket 203 is driven to move by starting the cylinder 202, and the lifting plate 3 can be smoothly raised and lowered by the sliding cooperation between each vertical guide rod 201 and the guide hole. The protective bracket 203 protects the drive motor 4 while maintaining the center alignment with the piston rod of the cylinder 202.
[0026] Bearing sleeves 9 are fixedly installed on the two opposite side walls of the U-shaped support frame 5. The two bearing sleeves 9 are respectively rotatably engaged with two rotating shafts 10 that are symmetrically fixed to the outer wall of the processing basket 6. The bearing sleeves 9 are provided with a first positioning hole 901 and a second positioning hole 902 that are distributed at 180° intervals. The rotating shaft 10 is provided with a third positioning hole 1001. The third positioning hole 1001 is aligned with the first positioning hole 901 or the second positioning hole 902 and is locked by the installation positioning bolt 11.
[0027] In this embodiment, when the third positioning hole 1001 is aligned and fixed with the first positioning hole 901, the processing basket 6 is in an open-up state, which facilitates loading and unloading of fish scale raw materials. When the third positioning hole 1001 is aligned and fixed with the second positioning hole 902, the processing basket 6 is in the open-down state, which facilitates the discharge of fish scales after ash soaking.
[0028] The top of the top cover 7 is equipped with a handle 701, and its outer periphery is provided with an external thread 702. The inner wall of the opening end of the processing basket 6 is provided with an internal thread 601 that mates with the external thread 702.
[0029] In this embodiment, by rotating the top cover 7, its external thread 702 engages with the internal thread 601 of the processing basket 6, thereby achieving reliable fastening and sealing of the top cover 7.
[0030] It also includes a delivery pump 12, the inlet of which is connected to a first delivery pipe 13 with a valve, and the outlet of which is connected to a second delivery pipe 14 with a valve. The inlet end of the first delivery pipe 13 extends to the bottom of the immersion tank 8, and the outlet end of the second delivery pipe 14 extends to the top of a filter tank 15. The top of the filter tank 15 is open, and a filter basket 16 is detachably fixed with bolts.
[0031] In this embodiment, the pump 12 is started to extract the ash liquid that has been reacted in the ash soaking tank 8 through the first conveying pipe 13, and then through the second conveying pipe 14 to the filter tank 15. After being filtered by the filter basket 16, the clear liquid is collected in the filter tank 15.
[0032] The inlet of the pump 12 is connected to a third delivery pipe 17 with a valve, and the outlet is connected to a fourth delivery pipe 18 with a valve. The inlet end of the third delivery pipe 17 extends to the bottom of the filter tank 15, and the outlet end of the fourth delivery pipe 18 extends to the top of the ash soaking tank 8.
[0033] In this embodiment, when the valves on the first conveying pipe 13 and the second conveying pipe 14 are closed and the valves on the third conveying pipe 17 and the fourth conveying pipe 18 are opened, the conveying pump 12 is started, and the clear liquid collected in the filter tank 15 is drawn and pumped back into the ash tank 8 through the fourth conveying pipe 18, so as to realize the recycling of ash liquid.
