Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment equipment, and in particular to a solid hazardous waste incineration and crushing device. Background Technology

[0002] The emergence of solid hazardous waste incineration and crushing equipment is primarily to address the environmental and safety issues arising from the large amounts of hazardous waste generated during industrial development. With rapid industrial growth, the amount of hazardous waste emitted during industrial production is increasing daily. It is estimated that the world generates 330 million tons of hazardous waste annually. If this hazardous waste is not properly treated, it will cause serious harm to the environment and human health.

[0003] Solid hazardous waste typically has a large volume and irregular shape. If it is not crushed during treatment, the material will accumulate loosely in the incinerator, resulting in a small contact area with oxygen. Insufficient oxygen supply will lead to incomplete combustion, reducing incineration efficiency, preventing the full release of heat, wasting energy, and potentially causing some hazardous waste to remain incinerated, prolonging incineration time and reducing overall treatment efficiency. Crushed solid hazardous waste has a large particle size variation, resulting in inconsistent combustion rates and degrees during incineration. Larger particles may burn incompletely, while smaller particles may burn too quickly, leading to reduced incineration efficiency and uneven heat transfer. Some areas will have concentrated heat, while others will have insufficient heat, reducing overall heat utilization efficiency, increasing energy consumption, and affecting production continuity.

Gears are installed on the outer rear ends of both first support rods, and these gears mesh with each other. When the right first support rod rotates, the meshing of the gears transmits power to the left first support rod, causing the two first support rods to rotate relative to each other.

This addresses the issue of concentrated heat in some areas and insufficient heat in others, leading to decreased overall heat utilization efficiency, increased energy consumption, and disruption of production continuity. Power is transmitted via a belt to the second pulley at the left end of the connecting rod, causing it to rotate. Eccentric weights are fixed to the outer sides of both ends of the connecting rod. As the connecting rod rotates, the eccentric weights undergo circular motion, generating periodic centrifugal force. Since the eccentric weights are installed inside the device housing, the centrifugal force generated by their rotation is transmitted to the frame through the support, causing the frame to vibrate at high frequency. This effectively improves combustion efficiency, extends equipment lifespan, reduces equipment maintenance costs and downtime frequency, and ensures the continuous and stable operation of the combustion system.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 - Figure 4 As shown: Solid hazardous waste incineration and crushing device, including box 1, the top of box 1 is connected to feed hopper 2, solid hazardous waste enters the device through feed hopper 2, and the solid hazardous waste is crushed by internal crushing mechanism 3. The crushing mechanism 3 is installed inside feed hopper 2.

[0032] The crushing mechanism 3 includes: a protective cover 301, a first motor 302, a chain 305, and two first support rods 307. The bottom of the protective cover 301 is fixedly connected to the top right side of the housing 1. The first motor 302 is located inside the protective cover 301, and the bottom of the first motor 302 is fixedly connected to the top right side of the housing 1. The protective cover 301 provides external protection for the first motor 302 inside, preventing the first motor 302 from being damaged by the outside.

[0033] The output end of the first motor 302 is fixedly connected to a first rotating rod 303. The left end of the first rotating rod 303 is fixedly connected to a first sprocket 304. The outer side of the first sprocket 304 meshes with the inner right side of the chain 305. Two first support rods 307 are connected through the inside of the feed hopper 2 on the left and right sides. The front end of the right first support rod 307 is fixedly connected to a second sprocket 306. The outer side of the second sprocket 306 meshes with the inner left side of the chain 305. After the first motor 302 is started, the first motor... The first rotating rod 303 on the output end of 302 drives the first sprocket 304 to rotate, and the outer side of the first sprocket 304 meshes with the chain 305 to make the chain 305 rotate. The second sprocket 306 is fixed on the front end of the first support rod 307 on the right side, and the second sprocket 306 meshes with the inner left side of the chain 305. So when the first sprocket 304 is driven, the first support rod 307 on the right side and the second sprocket 306 will also rotate inside the feed hopper 2.

[0034] Crushing rollers 308 are fixedly connected to the outer sides of both first support rods 307, and gears 309 are fixedly connected to the outer rear ends of both first support rods 307. The two gears 309 mesh with each other. By fixing the gears 309 to the rear ends of the two first support rods 307 and meshing the two gears 309, the right first support rod 307 is driven, and the left first support rod 307 rotates through the meshing of the two gears 309. At the same time, the crushing rollers 308 fixed to the outer sides of the first support rods 307 rotate synchronously to crush the solid hazardous waste material. When the material passes through the gap between the two crushing rollers 308, it will be gradually crushed into smaller particles and fall into the interior of the box 1.

[0035] like Figure 1 - Figure 5 As shown, a control panel 5 is fixedly connected to the right side wall of the protective cover 301, through which the entire device is controlled. A first guide plate 4 is fixedly connected to the inside of the top wall of the housing 1. The first guide plate 4 is located at the bottom of the feed hopper 2, and is used to initially guide the material to prevent it from failing to flow accurately into the interior of the frame 7 during downward conveying. A base 6 is fixedly connected to the bottom wall of the housing 1, and is used to support the bottom of the entire device.

[0036] like Figure 1 - Figure 9 As shown, the box 1 has a frame 7 inside, and a sieve plate 8 is fixedly connected inside the frame 7. The frame 7 is used to fix and support the sieve plate 8 on the outside to ensure that the material enters the inside of the frame 7 and falls into the sieve plate 8 for sieving.

[0037] A support plate 9 is fixedly connected to the top front side of the frame 7. A second motor 10 is installed on the top right side of the support plate 9. The support plate 9 is fixed to the top of the frame 7 and provides bottom support and fixation for the second motor 10. A second rotating rod 11 is fixedly connected to the output end of the second motor 10. Fixers 12 are installed on the outer side of the second rotating rod 11. The bottom walls of the two fixers 12 are fixedly connected to the top of the support plate 9. The fixers 12 support the second rotating rod 11 to ensure that the second rotating rod 11 can operate stably and in a balanced manner after being driven.

[0038] The left end of the second rotating rod 11 is fixedly connected to the first pulley 13, and the first pulley 13 is equipped with a belt 15. The frame 7 is connected through the inside of the frame 7. The outer side of the left end of the connecting rod 14 is fixedly connected to the second pulley 16. The rear side of the belt 15 is located inside the second pulley 16. When the second motor 10 is started, the second rotating rod 11 on the output end of the second motor 10 will rotate synchronously. It will be connected to the belt 15 through the first pulley 13 on the left end of the second rotating rod 11, thereby driving the belt 15 to rotate. The belt 15 will then be connected to the second pulley 16 on the left end of the connecting rod 14 inside the frame 7. After the first pulley 13 is driven, the belt 15 will drive the second pulley 16 and the connecting rod 14 to rotate inside the frame 7.

[0039] like Figure 1 - Figure 10As shown, device boxes 18 are fixedly connected to both the left and right sides of the frame 7. Supporters 17 are threadedly connected to both the left and right side walls of the two frames 7. The outer sides of the two supporters 17 are set inside the two device boxes 18. The outer sides of both the left and right ends of the connecting rod 14 are rotatably connected to the supporters 17. By setting the supporters 17 inside the device boxes 18 and fixing them to the front and rear side walls of the frame 7, the left and right ends of the connecting rod 14 are supported to ensure that the connecting rod 14 can operate stably and in a balanced manner.

[0040] Eccentric weights 19 are fixedly connected to the outer sides of both ends of the connecting rod 14. The two eccentric weights 19 are located inside the device box 18. When the connecting rod 14 is driven, the eccentric weights 19 at both ends of the connecting rod 14 perform circular motion, generating periodic centrifugal force. Since the eccentric weights 19 are installed inside the device box 18, the centrifugal force generated by their rotation is transmitted to the frame 7 through the support 17, causing the frame to vibrate at high frequency.

[0041] The front and rear sides of the frame 7 are connected by second support rods 20. The left and right ends of the two second support rods 20 are fixedly connected to the outer sides of the two second support rods 20. The front and rear side walls of the box 1 are fixedly connected to support frames 24. The bottom walls of the four connecting rings 21 and the upper side walls of the two support frames 24 are fixedly connected to sleeves 22. Springs 23 are fixedly connected inside each pair of upper and lower sleeves 22. Multiple springs 23 are connected through the bottom walls of the connecting rings 21 on the left and right ends of the connecting rings 21 and the sleeves 22 on the upper side walls of the support frames 24. After the upper and lower sleeves 22 are connected to the springs 23, the support frames 24 support the bottom of the frame 7, and the springs 23 play a buffering and vibration reduction role, ensuring the stability of the frame during vibration and effectively reducing the impact of vibration on the box.

[0042] like Figure 1 - Figure 11 As shown, a guide box 25 is fixedly connected to the bottom wall of the support frame 24. A first discharge plate 26 is connected to the left side of the guide box 25. The left side of the first discharge plate 26 is connected through to the left side wall of the box 1. A second discharge plate 27 is fixedly connected to the front side of the frame 7. The front side of the second discharge plate 27 is connected through to the front side wall of the box 1. After being screened by the sieve plate 8, qualified materials will fall into the interior of the guide box 25 through the sieve plate 8, and be discharged from the interior of the box 1 by the first discharge plate 26 and conveyed to the next device. In addition, unqualified materials will remain on the top of the sieve plate 8. By the vibration frequency driven by the sieve plate 8, these materials will be moved forward and discharged from the interior of the box 1 by the second discharge plate 27 on the front side for collection and further crushing.

[0043] It should be noted that this utility model is a solid hazardous waste incineration and crushing device. First, the first motor 302, control panel 5, and second motor 10 are connected to an external power source to supply power to the device.

[0044] The first motor 302, installed inside the protective cover 301, is the power source for the entire crushing mechanism. The bottom of the first motor is securely connected to the top right side of the housing 1. When activated, the first motor 302 generates rotational power, which is transmitted to the first rotating rod 303 through its output, causing it to rotate synchronously. The first sprocket 304, fixed to the left end of the first rotating rod 303, rotates along with the first rotating rod 303. The first sprocket 304 meshes with the inner right side of the chain 305, causing the chain 305 to begin cyclical motion. The inner left side of the chain 305 meshes with the second sprocket 306 at the front end of the right first support rod 307, thereby driving the second sprocket 306 and the connected right first support rod 307 to rotate. Gears 309 are installed on the outer rear ends of both first support rods 307, and these two gears mesh with each other. When the right first support rod 307 rotates, the power is transmitted to the left first support rod 307 through the meshing of gears, so that the two first support rods 307 can rotate relative to each other.

[0045] During the relative rotation of the two first support rods 307, the crushing rollers 308 fixed to the outside of the first support rods 307 rotate synchronously. When solid hazardous waste enters the crushing area inside the feed hopper 2, it will be subjected to the squeezing, shearing and rubbing action of the two crushing rollers 308. Due to the special tooth pattern or structure designed on the surface of the crushing rollers 308, the material will be gradually crushed into smaller particles when passing through the gap between the two crushing rollers 308. The material crushed by the crushing rollers 308 will fall into the box 1 from below the feed hopper.

[0046] After the solid hazardous waste is crushed, it falls into the frame 7 inside the housing 1. The second motor 10 is installed on the top right side of the support plate 9 to provide power to the screening mechanism. After the second motor 10 starts, its output end drives the second rotating rod 11 to rotate. The second rotating rod 11 is supported by the fixing device 12 to ensure the stability of the rotation. The first pulley 13 at the left end of the second rotating rod 11 rotates accordingly, and transmits power to the second pulley 16 at the left end of the connecting rod 14 through the belt 15, causing the connecting rod 14 to start rotating. Eccentric weights 19 are fixed on the outer sides of both the left and right ends of the connecting rod 14. When the connecting rod 14 rotates, the eccentric weights 19 make circular motion and generate periodic centrifugal force. Since the eccentric weights 19 are installed inside the device housing 18, the centrifugal force generated by their rotation is transmitted to the frame 7 through the support device 17, causing the frame to vibrate at high frequency.

[0047] The vibrating frame 7 drives the screen plate 8 to vibrate synchronously. The crushed material entering the box 1 from the feed hopper 2 jumps on the screen plate 8. Material that meets the screen hole size passes through the screen plate and falls into the guide box 25 below; material that does not meet the size continues to move on the screen plate and is discharged from the box through the second discharge plate 27 for further crushing.

[0048] The frame 7 is connected to the housing 1 by an elastic support system consisting of the second support rod 20, the connecting ring 21, the sleeve 22, and the spring 23. The spring 23 plays a buffering and vibration reduction role between the upper and lower sleeves, which can not only ensure the stability of the frame during vibration, but also effectively reduce the impact of vibration on the housing, and reduce noise and wear during equipment operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
