Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a waste biodegradation device. Background Technology

[0002] A large amount of fruit and vegetable waste is generated in daily life and agricultural production. 20%-50% of urban household waste in my country comes from fresh fruits and vegetables, accounting for 25%-30% of total fruit and vegetable production annually, amounting to over 100 million tons each year. The vast majority of this waste is not utilized for resource recovery and is treated as garbage along with other household waste. However, fruit and vegetable waste has a high water content, is easily perishable, and attracts insects. Mixing it with household waste increases its moisture content and lowers its calorific value, making it unsuitable for current landfill or incineration methods. Fruit and vegetable waste originates from relatively concentrated sources, making it easier to collect separately. Treating it at the source not only effectively addresses the environmental harm caused by fruit and vegetable waste but also reduces its collection costs.

[0003] Existing harmless treatment systems for fruit and vegetable waste are inconvenient to crush large pieces of waste during operation, which means that microorganisms can only start decomposing the waste from the surface. For harder parts, the decomposition speed is slower, significantly extending the treatment cycle.

[0004] To address the aforementioned issues, a waste biodegradation device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a waste biodegradation device that solves the problem in the prior art of inconvenience in crushing large pieces of waste, which significantly prolongs the excavation cycle.

[0010] As a further description of the above technical solution: both gears are located on the outside of the processing box, and the two gears are meshed together.

[0011] By adopting the above technical solution, a transmission function is achieved, which facilitates the synchronous rotation of two crushing rollers through two gears.

[0012] As a further description of the above technical solution: a first motor is fixedly connected to the outside of the processing box, and the output end of the first motor is fixedly connected to the rotating shaft at the rear.

[0013] By adopting the above technical solution, the first motor can drive the rear rotating shaft to rotate.

[0014] As a further description of the above technical solution: sprockets are fixedly connected above the outer rings of the two rotating rods, and chains are meshed with the outside of the two sprockets, with the chains located outside the degradation chamber.

[0015] By adopting the above technical solution, the two sprockets rotate synchronously via a chain.

[0016] As a further description of the above technical solution: a second motor is fixed on the top of the degradation box, and the output end of the second motor is fixedly connected to the rotating rod in front.

[0017] By adopting the above technical solution, the second motor can drive the front rotating rod to rotate.

[0018] As a further description of the above technical solution: the sealing plate is disposed in the expansion groove, and the outer side of the sealing plate is slidably connected to the inner wall of the expansion groove.

[0033] Reference Figure 2 and Figure 3 The cleaning assembly includes a cylinder 11, which is fixedly connected to the inner wall of the housing 10. A grooved plate 12 is fixedly connected to the output end of the cylinder 11. Evenly distributed springs 13 are fixedly connected inside the grooved plate 12. A brush plate 14 is fixedly connected to one end of each spring 13. A brush plate 14 is installed on the outer side between every two springs 13. The cylinder 11 of the cleaning assembly can drive the grooved plate 12 and multiple brush plates 14 to extend.

[0034] Reference Figure 1-4Two gears 5 are located on the outside of the processing box 1 and are meshed together to provide transmission, enabling the two crushing rollers 3 to rotate synchronously. A first motor 4 is fixedly connected to the outside of the processing box 1, and the output end of the first motor 4 is fixedly connected to the rear rotating shaft 2. The first motor 4 is a speed-regulating motor. The first motor 4 can drive the rear rotating shaft 2 to rotate. Sprockets 19 are fixedly connected to the upper outer ring of the two rotating rods 18, and chains 20 are meshed on the outside of the two sprockets 19. The chains 20 are located on the outside of the degradation box 17, and the two sprockets 19 rotate synchronously through the chains 20. A second motor 21 is fixedly connected to the top of the degradation box 17, and the output end of the second motor 21 is fixedly connected to the front rotating rod 18.

A sealing plate 27 is located inside the telescopic groove 25, and the outside of the sealing plate 27 is slidably connected to the inner wall of the telescopic groove 25, allowing the sealing plate 27 to extend and retract within the telescopic groove 25. A guide plate 15 is fixedly connected to the lower inner wall of the processing box 1.

[0035] Working Principle: The device is started by the controller 28, activating the first motor 4, whose output drives the rear rotating shaft 2. Since two gears 5 are fixed to the right side of the outer rings of the two rotating shafts 2 and mesh with each other, the rotation of the rear rotating shaft 2 drives the front rotating shaft 2 to rotate synchronously via the gears 5. This causes the crushing rollers 3 on the outer rings of the two rotating shafts 2 to rotate relative to each other, creating a shearing and crushing effect. Waste to be processed is fed into the top of the processing box 1, falling between the two crushing rollers 3, where it is cut and crushed into smaller particles by the relatively rotating rollers. The crushed particles fall onto the inclined guide plate 15 below the inner wall of the processing box 1. The inclined structure of the guide plate 15 guides the particles towards the discharge port 16 on the left. When it is necessary to clean the debris on the surface of the crushing rollers 3, the speed of the first motor 4 is directly adjusted via the controller 28. This reduces the rotational speed of the two crushing rollers 3. Simultaneously, the first electric push rod 8 retracts, causing the baffle 9 to enter the receiving groove 7. Then, the cylinder 11 pushes the grooved plate 12 to move inward into the processing box 1, allowing the brush plate 14 to pass through the through groove 6 and contact the surface of the crushing roller 3. A spring 13 is installed inside the grooved plate 12. Under the elastic force of the spring 13, the multiple brush plates 14 are tightly attached to the surface of the crushing roller 3, cleaning away residue as the crushing roller 3 rotates. After cleaning, the cylinder 11 drives the brush plates 14 back into the housing 10, and the first electric push rod 8 causes the baffle 9 to extend from the receiving groove 7, closing the through groove 6 and preventing waste particles from entering the housing 10 during the crushing process. The crushed waste particles enter the degradation chamber 17 through the discharge port 16, above the partition 23. Workers add biodegradable bacteria into the chamber 17 through the top feed cylinder, initially mixing the waste with the bacteria. The controller 28 activates the second motor 21, whose output drives the front rotating rod 18 to rotate. Since the sprockets 19 above the outer rings of the two rotating rods 18 are connected by a chain 20, the rotation of the front rotating rod 18 drives the rear rotating rod 18 to rotate synchronously, thus causing the stirring blades 22 below the outer rings of the two rotating rods 18 to rotate. The rotation of the stirring blades 22 thoroughly mixes the waste and bacteria above the partition 23, ensuring uniform mixing and accelerating the degradation reaction. Finally, the controller 28 controls the second electric push rod 26 in the telescopic groove 25 to retract, driving the sealing plate 27 to move into the telescopic groove 25, opening the discharge port 24 on the partition 23. Some of the degraded material will fall into the degradation box 17 below the partition 23 through the discharge port 24 for degradation. After degradation is completed, the degraded waste can be taken out by opening the sealing door on the lower outside of the degradation box 17.
