Description

Technical Field

[0001] This utility model belongs to the field of liquid filtration and separation technology, specifically, it relates to a rapid filtration device for animal fat residue pollutants. Background Technology

[0002] Animal fats are widely used in food processing, catering, and industrial production. However, during production, storage, and use, waste oils containing contaminants such as solid residues, colloids, and charred particles are often generated. These contaminants affect the quality, color, and subsequent processing performance of the oils, therefore effective filtration and purification treatment is essential.

[0003] Traditional grease filtration often uses static screens or filter cloths, where the grease to be filtered relies on gravity to naturally permeate. This method suffers from problems such as slow filtration speed, easy clogging, frequent shutdowns to clean filter residue, and high manual labor intensity. In particular, the filtration efficiency is especially low when processing animal fats with high viscosity and high impurity content.

[0004] Existing technologies include scraper-equipped filter devices that remove filter residue by using rotating scrapers inside the filter screen. While this alleviates clogging to some extent, it still has the following drawbacks: First, the scraping and discharge processes are often continuous, making it difficult to effectively seal the filter residue during discharge. This can lead to unfiltered grease short-circuiting into the discharge port, causing grease loss or secondary pollution. Second, the filtration driving force still mainly relies on the static pressure formed by the liquid level difference, resulting in limited improvement in filtration efficiency. Finally, the functionality is limited, and processes such as filtration, centrifugal separation, and sealing for grease discharge are not efficiently integrated, resulting in a low degree of automation.

[0005] To address the aforementioned issues, this application proposes a rapid filtration device for animal fat residue contaminants. Utility Model Content

[0006] In view of the problems in related technologies, this utility model proposes a rapid filtration device for animal fat residue pollutants to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rapid filtration device for animal fat residue pollutants includes a filter cylinder, a waste collection box installed at the bottom of the filter cylinder, an opening at the top of the waste collection box communicating with the filter cylinder, an installation ring fixedly installed on the inner wall of the filter cylinder, a fixing ring fixedly installed on the inner side of the installation ring, an annular filter screen installed on the top of the fixing ring, an inlet pipe installed at the top of the filter cylinder, a drain pipe installed on one side of the filter cylinder, and a door panel rotatably connected to one side of the waste collection box.

[0009] The centrifugal feeding mechanism includes a rotating shaft, which is movably mounted on the top of the filter cylinder. Multiple scrapers are fixedly mounted on the rotating shaft, and the scrapers are located inside the annular filter screen and are in contact with the inner wall of the annular filter screen.

[0010] Preferably, the centrifugal feeding mechanism further includes a conical feeding plate, which is fixedly installed at the bottom end of the rotating shaft, and the conical feeding plate is in contact with the inner wall of the fixing ring.

[0011] The conical discharge plate automatically discharges the pollutants filtered from above when it moves below the opening. The conical discharge plate is also designed to fit snugly against the inner wall of the fixing ring, preventing the filtered grease from leaking into the waste collection box through the opening.

[0012] Preferably, a guide hopper is fixedly installed on the top of the annular filter screen, and a conical guide plate is fixedly installed on the rotating shaft. The diameter of the conical guide plate is the same as the diameter of the bottom of the guide hopper.

[0013] The conical guide plate and the guide hopper work together to allow the grease liquid to be introduced when the conical guide plate moves out of the top of the guide hopper, and to seal the space between the conical guide plate and the guide hopper when the conical guide plate moves into the bottom of the guide hopper, thus enabling intermittent filtration.

[0014] Preferably, a fixing box is fixedly installed on the top of the filter cartridge, a motor is fixedly installed in the fixing box, a diamond-shaped output rod is fixedly installed on the output shaft of the motor, and the diamond-shaped output rod is slidably connected to the top of the rotating shaft.

[0015] The fixed box provides a fixed carrier for motor installation, and the diamond-shaped output rod is slidably connected to the top of the rotating shaft, so that when the diamond-shaped output rod rotates, it can drive the rotating shaft to rotate laterally, and the rotating shaft can also move up and down on the diamond-shaped output rod.

[0016] Preferably, a drive roller is fixedly installed on the rotating shaft. The drive roller is located inside the fixed box, and a cam groove is provided on the side of the drive roller. A positioning block is slidably connected to the inner wall of the cam groove, and the positioning block is fixedly connected to the inner wall of the fixed box.

[0017] The rotating drive roller is slidably connected to the positioning block through the cam groove, and the positioning block is fixed by the fixing box, so that the drive roller can rotate and move up and down at the same time, thereby driving the rotating shaft to move up and down when it rotates.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] The motor drives the shaft to rotate, causing the scraper to rotate inside the annular filter screen. This not only generates centrifugal force to accelerate liquid filtration, but also allows the scraper to adhere to the inner wall of the filter screen, removing attached contaminants in real time, preventing filter screen blockage, and significantly improving filtration efficiency and continuity.

[0020] The design employs a combination of a conical guide plate and a guide hopper: when the conical guide plate moves upward, it opens the liquid inlet channel; when it moves downward, it forms a seal with the guide hopper, achieving intermittent liquid inlet and filtration control. At the same time, the conical discharge plate fits against the inner wall of the fixed ring, opening the pollutant discharge channel when rotating downward and sealing to prevent grease leakage when moving upward, thus achieving automatic switching between filtration and slag discharge.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-4A rapid filtration device for animal fat residue pollutants includes a filter cylinder 1, a waste collection box 2 installed at the bottom of the filter cylinder 1, an opening 13 at the top of the waste collection box 2, the opening 13 being connected to the filter cylinder 1, an installation ring 12 fixedly installed on the inner wall of the filter cylinder 1, a fixing ring 10 fixedly installed on the inner side of the installation ring 12, an annular filter screen 5 installed at the top of the fixing ring 10, an inlet pipe 3 installed at the top of the filter cylinder 1, a drain pipe 4 installed on one side of the filter cylinder 1, and a door panel 11 rotatably connected to one side of the waste collection box 2.

[0029] The centrifugal feeding mechanism 6 includes a rotating shaft 61, which is movably installed on the top of the filter cylinder 1. Multiple scrapers 63 are fixedly installed on the rotating shaft 61. The scrapers 63 are located inside the annular filter screen 5 and are in contact with the inner wall of the annular filter screen 5.

[0030] Reference Figure 1 and Figure 2 The centrifugal feeding mechanism 6 also includes a conical feeding plate 62, which is fixedly installed at the bottom end of the rotating shaft 61. The conical feeding plate 62 fits against the inner wall of the fixing ring 10. A guide hopper 9 is fixedly installed on the top of the annular filter screen 5, and a conical guide plate 64 is fixedly installed on the rotating shaft 61. The diameter of the conical guide plate 64 is the same as the diameter of the bottom of the guide hopper 9. Through the cooperation between the conical guide plate 64 and the guide hopper 9, when the conical guide plate 64 moves out of the top of the guide hopper 9, it can feed the material upwards. When the grease is introduced, the conical guide plate 64 moves below the guide hopper 9, sealing the space between the conical guide plate 64 and the guide hopper 9, thus providing intermittent filtration. The conical discharge plate 62 automatically discharges the pollutants filtered above when it moves below the opening 13. The conical discharge plate 62 is also fitted to the inner wall of the fixing ring 10 to prevent the filtered grease from leaking into the waste collection box 2 through the opening 13.

[0031] Reference Figure 2A fixed box 68 is fixedly installed on the top of the filter cartridge 1. A motor 7 is fixedly installed in the fixed box 68. A diamond-shaped output rod 8 is fixedly installed on the output shaft of the motor 7. The diamond-shaped output rod 8 is slidably connected to the top of the rotating shaft 61. A drive roller 65 is fixedly installed on the rotating shaft 61. The drive roller 65 is located inside the fixed box 68, and a cam groove 67 is provided on the side of the drive roller 65. A positioning block 66 is slidably connected to the inner wall of the cam groove 67. The positioning block 66 is fixedly connected to the inner wall of the fixed box 68. Through the setting of the fixed box 68, It can provide a fixed carrier for the installation of motor 7, and the diamond-shaped output rod 8 is slidably connected to the top of the rotating shaft 61, so that when the diamond-shaped output rod 8 rotates, it can drive the rotating shaft 61 to rotate laterally, and the rotating shaft 61 can also move up and down on the diamond-shaped output rod 8. The rotating drive roller 65 is slidably connected to the positioning block 66 through the cam groove 67, and the positioning block 66 is fixed by the fixing box 68, so that it can drive the drive roller 65 to rotate and move up and down at the same time, thereby driving the rotating shaft 61 to move up and down when it rotates.

[0032] Working principle: During operation, the mixed grease is injected into the filter cylinder 1 through the inlet pipe 3 and guided into the annular filter screen 5 through the guide hopper 9. After filtration, it is discharged through the drain pipe 4. When the motor 7 is turned on, the output shaft of the motor 7 drives the diamond-shaped output rod 8 to rotate. The rotating diamond-shaped output rod 8 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the drive roller 65 to rotate. The rotating drive roller 65 is slidably connected to the positioning block 66 through the cam groove 67, and the positioning block 66 is fixed by the fixing box 68. Thus, the drive roller 65 can rotate and move up and down at the same time, which in turn drives the rotating shaft 61 to move up and down when it rotates. When the rotating shaft 61 moves, it drives the scraper 63 to rotate, thereby cleaning the grease in the annular filter screen 5. The grease liquid rotates, thus forming a centrifugal filter and increasing the filtration speed. When the rotating shaft 61 moves up and down, it drives the conical guide plate 64 and the conical discharge plate 62 to move up and down, thereby intermittently filtering the grease liquid and discharging the filtered contaminants. When the contaminants are discharged by the conical discharge plate 62, the grease liquid in the annular filter screen 5 is completely discharged into the filter cylinder 1 under the action of centrifugal force. The liquid height in the filter cylinder 1 is less than the height of the fixed ring 10 to prevent the grease liquid in the filter cylinder 1 from flowing back into the waste collection box 2 through the annular filter screen 5. The waste collection box 2 collects the grease liquid. Finally, the door panel 11 of the waste collection box 2 facilitates the removal and treatment of the filtered contaminants.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
