Description

Technical Field

[0001] This utility model relates to the field of organic solid waste treatment, and in particular to a high-efficiency and rapid dehydration device for the resource utilization of organic solid waste. Background Technology

[0002] The high-efficiency and rapid dewatering device for organic solid waste integrates mechanical pressing, hot air circulation, and vacuum negative pressure technologies. Through screw pressing for pre-dewatering, combined with multi-layer mesh belt conveying and gradient heating hot air evaporation, and a vacuum chamber to lower the boiling point of water, the dewatering cycle is significantly shortened. It is suitable for food waste, sludge, etc., achieving a dewatering rate of over 80%, facilitating subsequent resource recovery.

[0003] An efficient and rapid dewatering device for the resource utilization of organic solid waste includes: a pretreatment crushing unit, a screw press dewatering mechanism, a multi-layer mesh belt conveyor system, a hot air circulation heating module, a vacuum negative pressure chamber, and an automatic control system.

[0004] Current mainstream dewatering equipment has obvious technical limitations: although centrifugal dewatering machines have a large processing capacity, they can only separate free water and some interstitial water, and the removal effect on bound water is limited. The moisture content of the dewatered material is often higher than 70%. Ordinary filter presses face problems such as small processing capacity, easy clogging of filter cloth, and uneven pressure distribution, resulting in low dewatering efficiency and a final moisture content maintained at 60%-80%, which seriously restricts the resource utilization process of organic solid waste. Therefore, it is urgent to develop efficient and rapid dewatering devices to overcome the above bottlenecks. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency and rapid dewatering device for the resource utilization of organic solid waste. It aims to improve the problem that although the centrifugal dewatering machine in the existing technology has a large processing capacity, it can only separate free water and some interstitial water, and the removal effect on bound water is limited.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency and rapid dewatering device for the resource utilization of organic solid waste includes a frame, a transmission component on one side of the frame, a conveyor component inside the frame, a rear processing box fixedly connected to one side of the frame, a toothed roller rotatably connected inside the rear processing box, and the conveyor component including a variable diameter transmission rod, a spiral blade fixedly connected to the outer wall of the variable diameter transmission rod, and a filter network on the outer periphery of the spiral blade.

[0008] As a further description of the above technical solution:

[0009] A rotating box is provided on one side of the back-end processing box, and a motor is provided on one side of the rotating box. A main gear is fixedly connected to the drive end of the motor, and four auxiliary gears are meshed and connected to the outer wall of the main gear. A toothed roller is fixedly connected to one side of each of the four auxiliary gears.

[0010] As a further description of the above technical solution:

[0011] The variable diameter transmission rods are respectively a large rod, a medium rod, and a thin rod;

[0012] As a further description of the above technical solution:

[0013] The toothed roller is fixedly connected to the outside with teeth, and a rubbing roller is provided on one side of the toothed roller. The rubbing roller is rotatably connected to the inner wall of the rear processing box.

[0014] As a further description of the above technical solution:

[0015] The transmission assembly includes a belt motor, the drive end of which is rotatably connected to a transmission block. The outer wall of the transmission block has a movable groove, and a belt is slidably connected to the outer wall of the movable groove.

[0020] As a further description of the above technical solution:

[0021] The bottom of the spiral blade is fixedly connected to a protrusion.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the conveyor assembly features a unique variable-diameter transmission rod design, consisting of a large rod, a medium rod, and a thin rod. During the conveying of organic solid waste, the changing diameter gradually increases the extrusion pressure, enabling deep dehydration. The spiral blades, working in conjunction with the transmission rod, push the solid waste while simultaneously using the bottom protrusions to knead it, accelerating moisture separation. The filter network precisely traps solid waste while allowing moisture to pass through, ensuring a highly efficient and orderly dehydration process, significantly improving the efficiency and quality of organic solid waste dehydration.

[0024] 2. In this utility model, the back-end processing box provides working space for the toothed roller and the rubbing roller. The toothed roller and the rubbing roller cooperate, with the toothed roller increasing the contact and squeezing effect and the rubbing roller assisting in kneading, to perform secondary deep dewatering of the solid waste that has been initially treated by the conveyor, thereby enhancing the dewatering effect and making the organic solid waste more fully dewatered, laying a solid foundation for subsequent resource utilization and improving the overall processing efficiency of the device.

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.

[0033] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a highly efficient and rapid dewatering device for the resource utilization of organic solid waste, comprising a frame 1, a feed inlet 24 fixedly connected to the top of the frame 1, a transmission assembly 2 provided on one side of the frame 1, and a conveyor assembly 3 provided inside the frame 1. The conveyor assembly 3 transports organic solid waste, and utilizes a variable diameter transmission rod 7 and a spiral blade 8 in conjunction with a filter network 9 to gradually squeeze and filter the solid waste during transport, achieving preliminary dewatering. A rear processing box 4 is fixedly connected to one side of the frame 1, and a toothed roller 5 is rotatably connected inside the rear processing box 4. The conveyor assembly 3 includes a variable diameter transmission rod 7, a spiral blade 8 fixedly connected to the outer wall of the variable diameter transmission rod 7, and a filter network 9 provided on the outer periphery of the spiral blade 8. The variable diameter transmission rod 7 consists of a large rod 14, a medium rod 15, and a thin rod 16. A protrusion 25 is fixedly connected to the bottom of the spiral blade 8.

[0034] Reference Figure 2 , Figure 4 and Figure 5 A rotating box 10 is provided on one side of the rear processing box 4. The rear processing box 4 provides installation and working space for the toothed roller 5, the rubbing roller 18, etc., to further squeeze, knead and dewater the solid waste that has been initially processed by the conveyor assembly 3. A motor 11 is provided on one side of the rotating box 10. A main gear 12 is fixedly connected to the drive end of the motor 11. Four auxiliary gears 13 are meshed on the outer wall of the main gear 12. A toothed roller 5 is fixedly connected to one side of the four auxiliary gears 13. A tooth 17 is fixedly connected to the outside of the toothed roller 5. A rubbing roller 18 is provided on one side of the toothed roller 5. 18 is rotatably connected to the inner wall of the rear processing box 4. The transmission component 2 includes a belt motor 19. The transmission component 2 transmits power and transmits the power of the belt motor 19 to the variable diameter transmission rod 7, driving the conveyor component 3 to operate, realizing the conveying and dewatering process of organic solid waste. The drive end of the belt motor 19 is rotatably connected to a transmission block 20. The outer wall of the transmission block 20 is provided with a movable groove 21. The outer wall of the movable groove 21 is slidably connected to a belt 22. A connecting block 23 is slidably connected to one side of the belt 22. The connecting block 23 is fixedly connected to one end of the variable diameter transmission rod 7.

[0035] Working Principle: First, organic solid waste is fed into the feed inlet 24. The belt motor 19 starts, and its drive end drives the transmission block 20 to rotate. The belt 22 in the movable groove 21 on the outer wall of the transmission block 20 moves accordingly, and the power is transmitted to the variable diameter transmission rod 7 through the connecting block 23, causing the variable diameter transmission rod 7 to rotate. The spiral blades 8 on the variable diameter transmission rod 7 begin to push the solid waste forward. The bottom protrusions 25 of the spiral blades 8 enhance the squeezing and kneading effect on the solid waste. In the conveyor assembly 3, the solid waste is subjected to gradually changing pressure as the diameter of the variable diameter transmission rod 7 changes from the large rod 14 to the medium rod 15 and then to the thin rod 16. The water is separated and discharged through the filter network 9, achieving preliminary dehydration. The pre-treated solid waste is transported to the rear processing box 4. At the same time, the motor 11 drives the main gear 12 to rotate. The main gear 12 meshes with and drives the secondary gear 13, so that the toothed roller 5 rotates synchronously in the rear processing box 4, preparing for subsequent deep processing.

[0036] Solid waste entering the back-end processing tank 4 undergoes deep dehydration under the synergistic action of the toothed roller 5 and the rubbing roller 18. The teeth 17 on the outer wall of the toothed roller 5 increase the contact area and friction with the solid waste, working in conjunction with the rubbing roller 18 to squeeze and knead the solid waste. The variable-diameter transmission rod 7 continuously conveys the solid waste, ensuring that it is constantly subjected to the action of the toothed roller 5 and the rubbing roller 18 within the back-end processing tank 4, further crushing and squeezing it to fully separate residual moisture. Throughout the process, the frame 1 provides stable support, the transmission component 2 ensures effective power transmission, and the various components work together to achieve efficient and rapid dehydration of organic solid waste from initial squeezing and filtration to deep kneading and crushing. This lays the foundation for subsequent resource utilization, ensuring that the organic solid waste achieves good treatment results in the dehydration stage, facilitating subsequent composting, energy conversion, and other resource transformations.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
