Description

Technical Field

[0001] This utility model relates to the technical field of bio-based waste processing equipment, specifically a multi-stage screening and purification device for bio-based waste. Background Technology

[0002] Bio-based waste refers to waste generated during the production, processing, consumption, or natural cycle of living organisms (plants, animals, microorganisms, and their derivatives) that has lost its original use value. Its core characteristic is biodegradability (it can be broken down by microorganisms into harmless substances such as water and carbon dioxide), and the carbon element mainly comes from atmospheric carbon dioxide (fixed through plant photosynthesis). This distinguishes it from petroleum-based waste (such as non-degradable or recalcitrant waste like plastics and synthetic fibers). Bio-based waste must originate directly or indirectly from living organisms, not fossil fuels (such as coal and oil). For example, sawdust from felled trees is bio-based waste, while plastic bottles (petroleum-based) are not. Bio-based waste is generated in the natural environment (such as soil and water bodies). Under artificial degradation conditions (such as composting and anaerobic digestion), bio-based waste can be decomposed into harmless small molecules (such as CO2, H2O, and organic acids) by bacteria, fungi, and other microorganisms, and will not pollute the environment in the long term. Because of its "degradable + high organic matter" characteristics, bio-based waste is rarely directly landfilled (which easily produces greenhouse gases such as methane). Instead, it is mostly transformed into energy, materials, or fertilizers through resource utilization, which is in line with the concept of "circular economy". Bio-based waste is essentially organic waste that "comes from nature and returns to nature". Its core value is not in "waste", but in turning waste into treasure through scientific treatment, which reduces environmental pollution (avoids methane produced by landfill and toxic gases produced by incineration) and replaces fossil resources (reduces dependence on oil and coal).

[0003] Currently, after bio-based waste undergoes multi-stage screening, it is necessary to remove the dust and impurities adhering to the outside of the bio-based waste to improve its purity and enable better utilization. Most existing purification equipment uses conveyor belts to transport the waste and then wash it with water mist spray. Although this structure can purify the waste, it cannot remove stubborn dust and impurities, resulting in unsatisfactory purification effects. Therefore, we provide a multi-stage screening and purification device for bio-based waste to solve the above problems. Utility Model Content

[0005] This invention proposes a multi-stage screening and purification device for bio-based waste. Through the cooperation of the roller, the first motor, the scraper and the roller brush, it solves the problem that stubborn dust and impurities cannot be removed and the purification effect is not ideal.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage screening and purification device for bio-based waste, comprising a base plate and a drum, with two support seats mounted on the top of the base plate and the two support seats being symmetrical to each other, a rotating shaft rotatably connected to the inner wall of the support seat, the outer surface of the rotating shaft being rotatably connected to the inner wall of the drum, a flipping mechanism being provided on the outside of the drum, and a first motor mounted on one side of one of the support seats, the output shaft of the first motor being connected to one end of the rotating shaft;

[0008] A roller brush is connected to the outer surface of the rotating shaft, and the roller brush is located inside the drum. A frame is also connected to the outer surface of the rotating shaft, and a scraper is connected to the end of the frame. The outer surface of the scraper is in contact with the inner wall of the drum.

[0009] The inner side of the roller has a material inlet, and the inner wall of the material inlet is in contact with a cover plate. A drainage groove is connected to the bottom of the roller. A drainage hole is opened on the inner side of the roller, and the drainage hole corresponds to the drainage groove. A water injection pipe is connected to one side of the roller, and a drainage pipe is connected to one side of the drainage groove.

[0010] Furthermore, two uprights are connected to the top of the base plate, and the two uprights are symmetrical. A support plate is connected to the top of the uprights, and a hydraulic cylinder is installed above the support plate. The output end of the hydraulic cylinder is connected to the outer surface of the cover plate.

[0011] Furthermore, the upper surface of the cover plate is connected to four guide rods, and the four guide rods are located at the four corners of the cover plate. The outer surface of the guide rods is slidably connected to the inner wall of the support plate.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this multi-stage screening and purification device for bio-based waste has the following beneficial effects:

[0018] I. This multi-stage screening and purification device for bio-based waste utilizes the cooperation between a drum, a first motor, scrapers, and roller brushes. The internal space of the drum provides a container for the bio-based waste, while the first motor serves as the power source, powering the rotation of the roller brushes and scrapers. As the scrapers and roller brushes rotate, they continuously tumble and stir the bio-based waste inside the drum, causing the waste to rub and rub against each other, thus improving the purification effect and cleanliness of the bio-based waste.

[0019] II. The multi-stage screening and purification device for bio-based waste uses the cooperation between the second motor, gears and gear rings. The second motor is the power source, which provides power for the rotation of the gears. The roller receives the power from the gears through the gear ring, thereby driving the roller to rotate. The rotation of the roller positions the material inlet below the roller, which facilitates the pouring out of the cleaned bio-based waste inside the roller, improving the convenience of discharging bio-based waste.

[0028] 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.

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a multi-stage screening and purification device for bio-based waste, including a base plate 1 and a roller 2. Two support seats 3 are installed on the top of the base plate 1, and the two support seats 3 are symmetrical. A rotating shaft 4 is rotatably connected to the inner wall of the support seat 3. The outer surface of the rotating shaft 4 is rotatably connected to the inner wall of the roller 2. A first motor 6 is installed on one side of one of the support seats 3. The output shaft of the first motor 6 is connected to one end of the rotating shaft 4. The base plate 1 provides support for the components to be mounted, the support seats 3 provide support for the rotating shaft 4 and the roller 2, the space inside the roller 2 provides space for the bio-based waste, and the first motor 6 is the power source to provide power for the rotation of the rotating shaft 4, the roller brush 7, and the scraper 9.

[0030] A roller brush 7 is connected to the outer surface of the rotating shaft 4, and the roller brush 7 is located inside the drum 2. A frame 8 is also connected to the outer surface of the rotating shaft 4, and a scraper 9 is connected to the end of the frame 8. The outer surface of the scraper 9 is in contact with the inner wall of the drum 2. When the rotating shaft 4 rotates, it drives the roller brush 7 and the scraper 9 to rotate at the same time. After the roller brush 7 and the scraper 9 rotate, they continuously turn and stir the bio-based waste inside the drum 2. By turning, the bio-based waste is rubbed together, and the dust and impurities adhering to the outside are cleaned away. After the feed port 10 is opened, the rotation of the scraper 9 can also push the bio-based waste out from inside the drum 2 and clean the bio-based fertilizer out from inside the drum 2.

[0031] A feed inlet 10 is provided on the inner side of the drum 2. The drum 2 uses the feed inlet 10 to input and output bio-based waste. A cover plate 11 is in contact with the inner wall of the feed inlet 10. A drainage trough 12 is connected to the bottom of the drum 2. The drainage trough 12 collects the washed-off dust and impurities, preventing them from remaining inside the drum 2 along with the bio-based waste. A drain hole 13 is provided on the inner side of the drum 2. The drain hole 13 allows the cleaning fluid, dust, and impurities inside the drum 2 to flow into the drain trough 12 and drain out. Hole 13 corresponds to drain trough 12. A water injection pipe 14 is connected to one side of roller 2, and a drain pipe 15 is connected to one side of drain trough 12. The cleaning fluid inside roller 2 and drain trough 12 is discharged through drain pipe 15, and the cleaning fluid is injected into the inside of roller 2 through water injection pipe 14. Valves are installed on the outside of water injection pipe 14 and drain pipe 15 to control the opening and closing of water injection pipe 14 and drain pipe 15. Water injection pipe 14 and drain pipe 15 are both rubber hoses, which can adapt to the moving position of roller 2.

[0032] Two uprights 16 are connected to the top of the base plate 1, and the two uprights 16 are symmetrical. The top of the uprights 16 is connected to the support plate 17, and a hydraulic cylinder 18 is installed on the top of the support plate 17. The output end of the hydraulic cylinder 18 is connected to the outer surface of the cover plate 11. The uprights 16 provide support for the support plate 17 to maintain the stability of the support plate 17. The support plate 17 provides support for the hydraulic cylinder 18 to make the hydraulic cylinder 18 stable. The hydraulic cylinder 18 is the power source to provide power for the cover plate 11 to move up and down. After the cover plate 11 moves up, it opens the material port 10. After the cover plate 11 moves down, it seals the material port 10 to prevent the leakage of bio-based waste inside the roller 2.

[0033] Four guide rods 19 are connected to the upper surface of the cover plate 11, and the four guide rods 19 are located at the four corners of the cover plate 11. The outer surface of the guide rods 19 is slidably connected to the inner wall of the support plate 17. The upper surface of the support plate 17 is connected to the same number of sliding sleeves 20 as the guide rods 19. The outer surface of the guide rods 19 is slidably connected to the inner wall of the sliding sleeves 20. The guide rods 19 provide support force to the cover plate 11 to maintain the stability of the cover plate 11 when it moves up and down. The sliding sleeves 20 provide support force to the guide rods 19 to improve the stability of the guide rods 19.

[0034] The outside of the drum 2 is provided with a flipping mechanism 5, which enables the drum 2 to rotate. By rotating, the material inlet 10 is positioned below the drum 2, allowing the cleaned bio-based waste inside to be poured out. The flipping mechanism 5 includes a second motor 501, which is mounted on one side of another support 3. The output shaft of the second motor 501 is connected to a gear 502. The second motor 501 serves as the power source, providing power for the rotation of the gear 502. A gear ring 503 is connected to one side of the drum 2, and the gear ring 503 meshes with the gear 502. The drum 2 receives power from the second motor 501 through the gear ring 503, thereby driving the drum 2 to rotate.

[0035] A positioning block 21 is connected to one side of the roller 2, and a limit block 22 is connected to the upper surface of the support base 3. The limit block 22 is in contact with the positioning block 21, and the limit block 22 provides a block for the positioning block 21. After the positioning block 21 contacts the limit block 22, the rotation of the roller 2 is restricted, and the position of the roller 2 is set. In actual application, a rotation sensor is installed on the limit block 22. After the positioning block 21 contacts the limit block 22, the sensor is triggered. The sensor turns off the power of the second motor 501 through the control module, so that the roller 2 stops rotating.

[0036] The outer surface of the roller 2 is connected to a hopper 23, and the hopper 23 corresponds to the feed inlet 10. The hopper 23 has an outward tilting angle, which facilitates the filling of bio-based waste into the interior of the roller 2.

[0037] Working principle: During operation, bio-based waste is first injected into the drum 2 through inlet 10, while cleaning fluid is simultaneously injected into the drum 2 through water injection pipe 14. After the bio-based waste is filled, the hydraulic cylinder 18 is activated to push the cover plate 11 downwards. Once the cover plate 11 is in position, it contacts the inlet 10, sealing it. Then, the first motor 6 is started, driving the rotating shaft 4 to rotate. The rotating shaft 4 then drives the scraper 9 and roller brush 7 to rotate simultaneously. The rotating roller brush 7 and scraper 9 continuously agitate the bio-based waste inside the drum 2, causing the waste to rub and rub against each other, removing dust or impurities adhering to the surface of the bio-based waste. After cleaning the bio-based waste, turn off the first motor 6 and drain the cleaning solution through the drain pipe 15. After the cleaning solution inside the drum 2 is drained, start the hydraulic cylinder 18 to drive the cover plate 11 to disengage from the material inlet 10. Then start the second motor 501 to drive the gear 502 to rotate. After the gear 502 rotates, it drives the gear ring 503 and the drum 2 to rotate simultaneously. After the drum 2 rotates, the material inlet 10 is located below. Start the first motor 6 again to drive the rotating shaft 4 to rotate. After the rotating shaft 4 rotates, it drives the scraper 9 and the roller brush to rotate simultaneously again. While the scraper 9 rotates, it pushes out the bio-based waste inside the drum 2. When the drum 2 is reset and refilled with bio-based waste, the operation is reversed and the same operation is performed.
