Description

Technical Field

[0001] This utility model belongs to the field of municipal solid waste treatment technology, and in particular relates to a compression and recycling device for municipal solid waste treatment. Background Technology

[0002] Household waste refers to solid waste generated in daily life or in activities that provide services for daily life. With the acceleration of urbanization, the output of household waste continues to rise, with an annual growth rate of 5% to 8%. As an effective means of waste treatment, waste compression and recycling devices have received widespread attention and application in recent years. These devices compress household waste into high-density solids through compression, thereby greatly reducing the volume of waste and facilitating subsequent transportation and treatment.

[0003] However, in actual use, existing municipal solid waste compression and recycling devices are not convenient for adjusting the gap between the two compression rollers. Because municipal solid waste is complex and contains waste of various sizes, shapes and hardnesses, the gap between the compression rollers is difficult to adapt to the processing needs of all waste, resulting in some waste not being able to pass through the compression process smoothly, causing equipment blockage or overload. Utility Model Content

[0004] This utility model addresses the problem in existing technologies where municipal solid waste has a complex composition, containing waste of various sizes, shapes, and hardnesses. The gaps between the compression rollers are insufficient to accommodate the processing needs of all types of waste, leading to some waste failing to pass through the compression process, causing equipment blockage or overload. The following technical solution is proposed:

[0005] A compression and recycling device for municipal solid waste treatment includes a housing and an inlet. The housing has symmetrically fixed mounting plates inside, and two compression rollers are installed between the two mounting plates. A motor is fixedly mounted on the outer side of one of the mounting plates. The output shaft of the motor is fixedly connected to a rotating shaft. A first helical gear is fixedly sleeved on the outer surface of the rotating shaft near the motor end. A limit strip is fixedly mounted on the outer surface of the rotating shaft. A sliding sleeve is slidably mounted on the outer side of the limit strip, and a third helical gear is fixedly sleeved on the outer side of the sliding sleeve.

[0006] As a preferred embodiment of the above technical solution, the outer surfaces of the first helical gear and the third helical gear are both meshed with the outer side of the second helical gear.

[0007] As a preferred embodiment of the above technical solution, slide rails are fixedly installed on the outer sides of both mounting plates, and sliders are slidably installed on the top of the slide rails, with lead screws connected to the inside of the sliders via threads.

[0008] As a preferred embodiment of the above technical solution, a positioning rod is rotatably sleeved on the outer side of the sliding sleeve, a connecting rod is fixedly connected to the outer side of the slider, and the other end of the connecting rod is fixedly connected to the outer surface of the positioning rod.

[0009] As a preferred embodiment of the above technical solution, a first baffle is fixedly connected to one end of the lead screw, and a second baffle is fixedly sleeved on the outer side of the rotating shaft at the positions corresponding to the two ends of the limiting strip.

[0010] As a preferred embodiment of the above technical solution, an inclined plate is fixedly connected between the two mounting plates, and side plates are fixedly connected to the front and rear ends of the inclined plate. A recycling box is installed inside the box at one end of the inclined plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) This utility model adjusts the position of the extrusion roller on the right side inside the equipment by rotating the screw, thereby realizing the controllable adjustment of the gap between the two extrusion rollers. It enables the equipment to adjust the position of one of the extrusion rollers according to the actual situation during actual operation, ensuring that the waste being processed can pass through the extrusion process smoothly and improving the processing efficiency.

[0013] (2) By installing baffle one and baffle two at the ends of the lead screw and the limiting bar, the slider and the third gear will not slip off the slide rail and the limiting bar during the movement of the slider and the third gear, thus ensuring that the slider and the third gear can operate normally.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1: This utility model provides a compression and recycling device for municipal solid waste treatment, such as... Figures 1 to 5 As shown, it includes: a housing 1 and a feed inlet 2. Inside the housing 1, mounting plates 3 are symmetrically fixedly installed. Two extrusion rollers 4 are installed between the two mounting plates 3. The left extrusion roller 4 is rotatably mounted between the two mounting plates 3, while the right extrusion roller 4 is slidably mounted between the two mounting plates 3. A motor 5 is fixedly mounted on the outer side of one of the mounting plates 3. The output shaft of the motor 5 is fixedly connected to a rotating shaft 51. A first helical gear 6 is fixedly sleeved on the outer surface of the rotating shaft 51 near the motor 5. A limit strip 8 is fixedly installed on the outer surface of the rotating shaft 51. A sliding sleeve 9 is slidably mounted on the outer side of the limit strip 8. A third helical gear 10 is fixedly sleeved on the outside. The outer surfaces of the first helical gear 6 and the third helical gear 10 are meshed with the outer side of the second helical gear 7. When the motor 5 is started, it drives the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it drives the first helical gear 6 and the third helical gear 10 on its outer side to rotate synchronously. When the first helical gear 6 and the third helical gear 10 rotate, they drive the second helical gear 7 at the corresponding position to rotate through the meshing connection. This causes the two extrusion rollers 4 to rotate towards each other, thereby extruding the domestic waste entering through the feed inlet 2, effectively reducing the volume of the waste, and facilitating the smooth progress of subsequent packaging and transportation.

[0022] like Figure 4 and Figure 5As shown, slide rails 11 are fixedly installed on the outer sides of both mounting plates 3. A slider 12 is slidably installed on the top of the slide rail 11. The rolling shaft of the right-side squeezing roller 4 is rotatably installed inside the slider 12. A screw 15 is threadedly connected inside the slider 12. A positioning rod 14 is rotatably sleeved on the outer side of the sliding sleeve 9. A connecting rod 13 is fixedly connected to the outer side of the slider 12. The other end of the connecting rod 13 is fixedly connected to the outer surface of the positioning rod 14. By rotating the screw 15, the slider 12 is driven to slide on the slide rail 11 through the threaded connection. When the slider 12 slides, the positioning rod 14 is driven to slide synchronously through the action of the connecting rod 13. The positioning rod 14 is rotatably sleeved on the outer surface of the sliding sleeve 9, so that when the positioning rod 14 moves, it drives the sliding sleeve 9 to slide on the limiting strip 8. This realizes the synchronous sliding of the right-side squeezing roller 4, the second helical gear 7, and the third helical gear 10, and realizes the adjustment of the position of one of the squeezing rollers 4. It is convenient to adjust the gap between the two squeezing rollers 4 and realize the squeezing work of different types of waste.

[0023] like Figures 3 to 5 As shown, a baffle plate 151 is fixedly connected to one end of the lead screw 15, and a baffle plate 16 is fixedly sleeved on the outer side of the rotating shaft 51 at the two ends of the limiting strip 8. During the sliding of the slider 12 on the slide rail 11, the slider 12 will not slip off the lead screw 15 due to the restriction of the baffle plate 151. At the same time, when the slider 12 moves and drives the positioning rod 14 to run synchronously, the baffle plate 16 is installed at both ends of the limiting strip 8, thereby ensuring that the third helical gear 10 will not slip off the limiting strip 8 due to sliding, thus ensuring the normal operation of the slider 12 and the third helical gear 10.

[0024] like Figure 1 and Figure 2 As shown, an inclined plate 17 is fixedly connected between the two mounting plates 3. Side plates 171 are fixedly connected to the front and rear ends of the inclined plate 17. A recycling box 18 is installed inside the box 1 at one end of the inclined plate 17, so that the household waste compressed by the two compression rollers 4 falls onto the inclined plate 17. Under the action of the inclined plate 17, the compressed waste slides into the recycling box 18 due to its own gravity, thereby realizing the centralized collection of the compressed waste. At the same time, as the waste slides down the inclined plate 17, the side plate 171 can effectively prevent the waste from slipping off the inclined plate 17, ensuring that the compressed household waste can smoothly slide into the recycling box 18.

[0025] Working principle: In actual use, the staff rotates the lead screw 15 to drive the slider 12 to run on the slide rail 11 according to the size and type of household waste to be squeezed. This drives the right-side squeezing roller 4 to slide. At the same time, the slider 12 moves, and the positioning rod 14 moves through the connecting rod 13. When the positioning rod 14 moves, it drives the sliding sleeve 9 to slide on the limit strip 8, thereby realizing the synchronous adjustment of the position of the right-side squeezing roller 4, the second helical gear 7 and the third helical gear 10. After the distance between the two squeezing rollers 4 is adjusted, the motor 5 is started. When the rotating shaft 51 rotates, it drives the first helical gear 6 and the third helical gear 10 to rotate synchronously. When the first helical gear 6 and the third helical gear 10 rotate, they drive the second helical gear 7 on the two squeezing rollers 4 to rotate synchronously, thereby realizing the synchronous opposite rotation of the two squeezing rollers 4, realizing the squeezing of household waste, compressing the volume of the waste. The squeezed waste falls onto the inclined plate 17 and slides down the inclined surface of the inclined plate 17 into the recycling box 18, realizing the automatic collection of the squeezed waste, which is convenient for subsequent packaging and transportation.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
