Description

Technical Field

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

[0002] With the acceleration of industrialization and urbanization, the amount of solid waste generated is increasing year by year. Traditional treatment methods face problems such as resource waste, secondary pollution and land occupation. For example, direct landfilling of uncompressed solid waste will occupy a large amount of land resources, while inefficient sorting technology will cause recyclables to be mixed with hazardous substances, reducing the resource utilization rate. Therefore, the development of efficient and environmentally friendly recycling equipment has become a core demand of the industry.

[0003] In the solid waste treatment process, the screening stage, as the initial process, plays a crucial role in classification. Currently, the widely used drum screens use the centrifugal force generated by their own rotation to classify solid waste by particle size. However, traditional equipment is only equipped with a single drum structure. This design has obvious limitations in actual operation. A single screening can only separate two different particle sizes of waste. This mode not only limits the efficiency of multi-level classification, but also requires repeated screening processes when dealing with complex mixed waste, resulting in a significant reduction in overall processing efficiency and making it difficult to meet the needs of large-scale waste treatment. Therefore, we propose a recycling device for solid waste treatment. Utility Model Content

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a recycling device for solid waste treatment, including a base 3, a conveyor belt 4, and a base plate 6, and further including:

[0025] The outer roller 2 is movably mounted on top of the base 3;

[0026] The inner roller 1 is rotatably installed inside the outer roller 2, and its screen holes are larger than those of the outer roller 2, so that different waste materials can be separated.

[0027] The drive cleaning assembly 5 is mounted on the base 3 and is used to drive the inner roller 1 and the outer roller 2 to rotate and screen solid waste. The inner roller 1 and the outer roller 2 rotate in opposite directions.

[0028] The drive cleaning assembly 5 includes four connecting plates 56 set on the top of the base plate 6. A shaft 53 is rotatably set between each pair of opposite connecting plates 56. A brush cylinder 51 is fixedly sleeved on the outer surface of each of the two shafts 53. The two brush cylinders 51 are respectively movably set on the outer surface of the outer roller 2. When the shaft 53 rotates, it will drive the brush cylinder 51 to clean the outer roller 2. This can prevent waste material from getting stuck in the outer roller 2 and improve efficiency.

[0029] A motor 52 is installed at one end of the shaft 53 through the side of the connecting plate 56. The motor 52 is installed at the top of the base plate 6. A pulley 54 is fixedly sleeved on the outer surface of the shaft 53, and an annular groove 7 is opened on the outer surface of the outer roller 2. The pulley 54 is movably installed on the inner wall of the annular groove 7. The outer roller 2 is driven to rotate by rotating the pulley 54.

[0030] A transmission gear 55 is fixedly sleeved on the outer surface of the shaft 53. A side plate 59 is provided on the top of the base plate 6. A rotating rod 510 is rotatably mounted on the side of the side plate 59. A driven gear 57 is fixedly sleeved on the outer surface of the rotating rod 510. The driven gear 57 and the transmission gear 55 mesh with each other. A pulley 58 is fixedly sleeved on the outer surface of the rotating rod 510. An annular groove 8 is opened on the outer surface of the inner roller 1. The outer surface of the pulley 58 is movably mounted on the inner wall of the annular groove 8. The pulley 58 will drive the inner roller 1 to rotate, which is achieved through the cooperation of the driven gear 57 and the transmission gear 55.

[0031] Four support rods 10 are fixedly installed on the top of the base plate 6. Arc-shaped baffles 9 are installed on the end faces of the four support rods 10. The outer side of the arc-shaped baffles 9 is movably installed on the top of the inner wall of the outer roller 2. The arc-shaped baffles 9 are designed to prevent the outer roller 2 from throwing out waste materials.

[0032] Two fixing plates 12 are provided on the inner side of the arc-shaped baffle 9. Arc-shaped brush plates 11 are provided at the bottom of the two fixing plates 12. The inner sides of the two arc-shaped brush plates 11 are movably disposed on the outer surface of the inner roller 1. The arc-shaped brush plates 11 can clean the outer surface of the inner roller 1 and prevent waste from getting stuck.

[0033] When using this device, solid waste is first fed into the inner drum 1. Starting the motor 52 causes the shaft 53 to rotate, which in turn drives pulley 54 to rotate. Pulley 54 is located on the inner wall of the annular groove 7, thus causing the outer drum 2 to rotate. The shaft 53 also drives the transmission gear 55 to rotate, which in turn drives the meshing driven gear 57 to rotate. The driven gear 57 then drives the rotating rod 510 to rotate, causing the rotating rod 510 to rotate. The rotating rod 510 then drives pulley 58, which is sleeved on the outer surface, to rotate. Pulley 58 slides on the inner wall of the annular groove 8, thereby causing the inner drum 1 to rotate. The inner drum 1 performs the first separation of the waste material from the inner wall, which then enters the inner wall of the outer drum 2. The waste material is then separated onto the conveyor belt 4 by the outer drum 2 and continues to move. The outer drum 2 then separates another type of waste material, thus completing the screening of three different types of waste.

[0034] Example 2: Please refer to Figure 6 This utility model provides a technical solution: multiple balls 13 are movably embedded in the outer side of the arc-shaped baffle 9. The multiple balls 13 are movably disposed on the inner wall of the outer roller 2. By setting the balls 13 in the arc-shaped baffle test tube, the friction between the inner wall of the outer roller 2 and the ball 13 can be effectively reduced, thereby increasing the service life.
