Description

Technical Field

[0001] This utility model relates to the field of donkey-hide gelatin processing, specifically a centrifugal filtration device for donkey-hide gelatin processing. Background Technology

[0002] Donkey-hide gelatin (Ejiao) is a traditional Chinese medicine, mainly made from donkey skin. It has the effects of nourishing blood, yin, and moisturizing dryness. In the process of processing donkey-hide gelatin, the cleaned donkey skin needs to be put into a pot, water is added, and it is simmered over low heat. This process may take up to 12 hours or more. The longer the simmering time, the better the quality of donkey-hide gelatin. During the simmering process, it is necessary to check it regularly to avoid excessive evaporation of water. After the simmering is completed, the raw materials need to be filtered using a filtration system.

[0003] Existing technology, such as the centrifugal filtration device for processing donkey-hide gelatin disclosed in Chinese Publication No. CN211099620U, includes a filter tank. A support foot is fixed to the bottom of the filter tank, and a pneumatic rod is embedded in the middle of the bottom of the filter tank. A fixed rotating seat is provided at the telescopic end of the pneumatic rod, and an arc-shaped retaining pad is provided above the fixed rotating seat. The fixed rotating seat is rotatably connected to the arc-shaped retaining pad via a bearing. A discharge pipe is provided on one side of the filter tank at the bottom, and a sealed door is provided on the front side of the filter tank at the middle. A water inlet is provided on the other side of the filter tank at the top, and an annular cleaning pipe is connected to the outlet of the water inlet. A centrifugal motor is fixed to the top of the filter tank at the middle, and a feed inlet is provided on one side of the centrifugal motor. A centrifugal mechanism is fixed to the end of the centrifugal motor.

[0004] The centrifugal mechanism includes a drive shaft fixed to the end of a centrifugal motor. A positioning bracket is fixed to the outside of the drive shaft. A filter cartridge is engaged with the inside of the positioning bracket. A connecting rod is fixed to one side of the positioning bracket. A scraper is fixed to the top of the connecting rod.

[0005] In existing centrifugal filtration technology, although scrapers are used to clean the inner cylinder of the equipment, a lot of material accumulates on the scrapers during centrifugation, resulting in residues on the scraper surface that can form stubborn stains over time. Furthermore, existing technology does not clean the scraper surface. Additionally, although a sealing structure is used to seal the bottom of the centrifuge cylinder, the upper centrifuge cylinder rotates while the bottom plate remains stationary, thus affecting the centrifugation effect. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a centrifugal filtration device for processing donkey-hide gelatin, so as to solve the technical problems of inconvenient cleaning of scraper and non-rotation of bottom plate affecting centrifugation effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal filtration device for processing donkey-hide gelatin, comprising a filter tank, a motor installed at the top of the filter tank, a connecting frame connected to the output end of the motor, a filter screen fixed to the outside of the connecting frame, a lifting cylinder installed at the bottom of the filter tank, a base plate connected to the output end of the lifting cylinder, and multiple sets of limiting grooves formed on the outside of the base plate, the base plate fitting against the bottom end of the filter screen, and a rod matching the limiting groove connected to the bottom end of the connecting frame, multiple sets of pushing cylinders connected around the motor at the top of the filter tank, and a scraper installed inside the filter tank at the output end of the pushing cylinder, the outer wall of the scraper fitting against the inner wall of the filter tank, and the inner wall of the scraper fitting against the outer wall of the filter screen.

[0008] By adopting the above technical solution, the raw materials can be easily separated. During the separation process, the bottom plate is driven to rotate synchronously with the filter screen by the connecting frame, which improves the rotation efficiency of the raw materials. At the same time, the scraper can clean the inside of the filter tank and the outside of the filter screen.

[0009] The present invention is further configured such that the top of the filter tank is connected to a feed inlet, and the bottom end of the feed inlet extends into the interior of the filter tank and is located in the middle of the filter screen; the bottom of the filter tank is equipped with a discharge port, and the discharge port is located on the outside of the base plate; and the bottom of the filter tank is also connected to a base.

[0010] Preferably, the raw material can be easily injected into the inside of the filter screen, and the filtered raw material can be discharged through the discharge port.

[0011] The present invention is further configured such that a support rod is connected to the outer side of the connecting frame, the support rod is in contact with the inner wall of the filter screen, and the insertion rod is installed at the bottom end of the support rod.

[0012] Preferably, it allows for easy support of the filter screen, thereby increasing its strength.

[0013] The present invention is further configured such that a water spraying pipe is installed inside the filter tank, the water spraying pipe is located at the top of the inner wall of the filter tank, and the lifting cylinder is aligned with the top of the scraper.

[0014] Preferably, water can be sprayed into the filter tank to facilitate cleaning of the inside of the filter tank.

[0015] The present invention is further configured such that water-permeable holes are provided on both the inner and outer sides of the scraper, so that water discharged from the sprinkler pipe can enter the bottom of the filter tank through the water-permeable holes.

[0016] Preferably, the water is allowed to flow into the bottom of the filter tank through the permeable holes.

[0017] The present invention is further configured such that the base plate has a conical structure, and when the base plate moves upward, it engages with the insertion rod through a limiting groove.

[0018] Preferably, it facilitates the separation of raw materials.

[0019] The present invention is further configured such that the outer edge of the scraper is a beveled structure, and the scraper fits against the inner wall of the filter tank through the bevel.

[0020] Preferably, this reduces wear on the inner wall of the filter tank when the scraper moves up and down.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model, through the setting of a push cylinder and a scraper, can drive the scraper to move up and down, so that the scraper can clean the inner wall of the filter tank and the outer side of the filter screen. During the cleaning process, water is supplied to the top of the scraper through a water spray pipe. The water flows into the inner side of the filter tank through the edge opening of the scraper, which also cleans the impurities attached to the scraper, thus improving the cleaning effect.

[0023] 2. This utility model, through its support frame, filter screen, and base plate, enables the filtering of donkey-hide gelatin raw materials. First, the lifting cylinder is activated to push the base plate to fit against the bottom of the filter screen, and the insertion rod is inserted into the limiting groove to limit the base plate. Then, the motor is started to drive the support frame to rotate. The support frame rotates synchronously with the filter screen and the base plate, performing centrifugal filtration of the donkey-hide gelatin raw materials. The synchronous rotation of the base plate and the filter screen improves the centrifugal treatment effect and avoids the accumulation of some raw materials that cannot be centrifuged and filtered.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Please see Figures 1 to 5 The system includes a filter tank 1, a motor 2 mounted on its top, a connecting frame 4 connected to the output of the motor 2, a filter screen 6 fixed to the outside of the connecting frame 4, a lifting cylinder 8 mounted on the bottom of the filter tank 1, a base plate 7 connected to the output of the lifting cylinder 8, a feed inlet 101 connected to the top of the filter tank 1, and the bottom of the feed inlet 101 extending into the interior of the filter tank 1 and located in the middle of the filter screen 6, allowing raw materials to be injected into the filter screen 6. A discharge port 102 is mounted on the bottom of the filter tank 1, located on the outside of the base plate 7, and can be driven by the motor 2 to rotate the connecting frame 4, which in turn drives the outer filter screen 6 to rotate, thereby centrifugally separating the raw materials. A base 103 is also connected to the bottom of the filter tank 1, and multiple sets of limiting grooves 701 are formed on the outside of the base plate 7, which fits snugly against the bottom of the filter screen 6. A support rod 401 is connected to the outside, and the support rod 401 is attached to the inner wall of the filter screen 6. The insertion rod 402 is installed at the bottom end of the support rod 401. The bottom plate 7 has a conical structure. When the bottom plate 7 moves upward, it is engaged with the insertion rod 402 through the limiting groove 701, so that the insertion rod 402 can drive the bottom plate 7 to rotate synchronously. Multiple sets of pushing cylinders 3 are connected around the top of the filter tank 1 around the motor 2. The output end of the pushing cylinder 3 extends into the interior of the filter tank 1 and is equipped with a scraper 5. The outer wall of the scraper 5 is attached to the inner wall of the filter tank 1, and the inner wall of the scraper 5 is attached to the outer wall of the filter screen 6. A water spray pipe 9 is installed inside the filter tank 1. The water spray pipe 9 is located at the top of the inner wall of the filter tank 1, and the lifting cylinder 8 is aligned with the top of the scraper 5. After centrifugation, the inner wall of the filter tank 1 and the outer side of the filter screen 6 can be cleaned by the up and down movement of the scraper 5.

[0034] In the above embodiment, please refer to the figure for details. Both the inner and outer sides of the scraper 5 are provided with water permeable holes, and the water discharged from the sprinkler pipe 9 can enter the bottom of the filter tank 1 through the water permeable holes.

[0035] In the above embodiment, please refer to the figure for details. The outer edge of the scraper 5 is a beveled structure, and the scraper 5 is attached to the inner wall of the filter tank 1 through the bevel.

[0036] During use, firstly, the lifting cylinder 8 is activated, pushing the base plate 7 upward. The base plate 7 then aligns with the bottom end of the filter screen 6, and at this time, the insertion rod 402 is inserted into the limiting groove 701 on the base plate 7, thus connecting the connecting frame 4 and the base plate 7. Next, raw materials need to be injected into the filter tank 1 through the feed inlet 101 into the filter screen 6. The raw materials accumulate inside the filter screen 6. Then, the motor 2 is activated, and its output drives the connecting frame 4 to rotate. The connecting frame 4, through the support rod 401, drives the outer filter screen 6 to rotate synchronously. The insertion rod 402 also drives the bottom plate 7 to rotate, thereby discharging the raw materials accumulated inside the filter screen 6. The material is centrifuged, and the separated raw material is discharged through the discharge port 102. After the mixing is completed, the upper push cylinder 3 is activated, which drives the scraper 5 to move downward to scrape off the material on the inner wall of the filter tank 1 and the material on the outer side of the filter screen 6. At the same time, the water spray pipe 9 is activated to inject water above the scraper 5 and spray it into the filter tank 1 through the opening on the scraper 5, which facilitates the cleaning of the inside of the filter tank 1. After cleaning, the lifting cylinder 8 is activated to drive the bottom plate 7 to move downward, so that the bottom plate 7 separates from the filter screen 6. The remaining impurities are discharged from the filter screen 6 and then discharged through the discharge port 102, thus cleaning the filter screen 6.
