Description

Technical Field

[0001] The invention relates to the technical field of waste incineration power generation, in particular to a waste crushing and drying device for waste incineration power generation. Background Art

[0002] Garbage crushing and drying device is a kind of equipment used for garbage treatment. Its main function is to crush and dry garbage to reduce the volume of garbage for subsequent treatment or incineration. This device plays an important role in modern garbage treatment systems and can effectively promote the resource utilization of garbage.

[0003] In the prior art, garbage is usually crushed and dried before incineration. However, when the existing garbage is recycled, it is easy to cause blockage and damage inside the crushing and drying device due to the different sizes of the garbage.

[0004] In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (publication number CN110898951A) discloses a kitchen waste drying and crushing device, including a storage barrel and an extrusion barrel, wherein the storage barrel and the extrusion barrel are connected by a feeding pipe, a pressing mechanism is arranged in the storage barrel, a single screw is arranged inside the extrusion barrel, and the single screw is controlled by a driving motor connected thereto, and the extrusion barrel is also provided with a discharge port and a drain port. The present invention adopts an independent storage barrel for feeding, and completes the upward conveying of kitchen waste by means of the extrusion conveying action of a vertical extrusion barrel and a single screw, and completes the shredding and drying of kitchen waste under the drying action of a heater. The processed kitchen waste powder has a dry texture and greatly reduced odor. The dried kitchen waste powder can be widely used in feed processing and returning to the field for fertilization, solving the hygiene problems and high-value utilization problems of kitchen waste.

[0005] In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (publication number CN107552173A) discloses a garbage crushing device, including a shell, a crushing and stirring mechanism and a spray drying mechanism.

A guide tube is arranged in the middle of the shell, and a slag discharge pipe is arranged at the bottom of the guide tube. The garbage crushing device of the present invention has a simple structure and is easy to use. It performs dry crushing and wet crushing on the garbage in turn, and mixes it with water to form a slurry, so that the garbage can be discharged from the slag discharge pipe. After the slurry garbage is discharged, a cleaning agent, a bactericide and a drying gas are introduced into the shell in turn to clean, sterilize and dry the inside of the shell, so that the device is in a dry and sterile environment after processing the garbage, thereby improving the hygiene and safety of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the embodiment, a uniform drying component is provided which can improve the degree of drying of the garbage after crushing. When in use, garbage is added to the crushing box 2 through the feeding port 3, and the incinerated garbage used for power generation falls into the filter iron mesh 7 inside the limiting block 6. Due to the limitation of the filter iron mesh 7, larger pieces of garbage are filtered so that they remain on the surface of the filter iron mesh 7. At this time, as the driving motor 4 is started, the output end of the driving motor 4 drives the crushing rod 5 to rotate. When the crushing rod 5 rotates, the larger pieces of garbage on the surface of the filter iron mesh 7 are crushed. At this time, as the garbage is crushed, it can pass through the filter iron mesh 7. The garbage that passes through the filter iron mesh 7 falls on the surface of the lifting plate 15. At this time, as the electric fan 17 is started, the electric fan 17 blows air upward after starting. At this time, the heat conductive wire 19 is heated by the heater 18. Under the heat, the wind blown out by the electric fan 17 is heated to achieve the effect of blowing hot air, so that the hot air is blown upward to dry the garbage fragments on the surface of the lifting plate 15, and the blown wind passes through the air outlet 8 to take the moist air away from the inside of the drying box 1. At this time, with the rotation of the crushing rod 5, the driving rod 10 can be driven to rotate synchronously through the setting of the transmission belt 9. The rotation of the driving rod 10 drives the rotating cross bar 12 to rotate through the first bevel gear set 11 at the bottom. When the rotating cross bar 12 rotates, it pushes the lifting plate 15 to pull up and down the reset spring 14, so that the garbage fragments on the surface of the lifting plate 15 can be driven to vibrate under the reciprocating vibration of the reset spring 14. With the hot air blown out from the bottom, the efficiency of garbage drying can be improved, which is convenient for the use of the staff and reduces the time required for drying.

[0041] In the embodiment, when in use, as the crushing rod 5 crushes the garbage on the surface of the filter iron net 7, the driving rod 10 rotates synchronously. As the driving rod 10 rotates synchronously, the second cam 20 at the middle end pushes the knocking block 23, and the knocking block 23 is pushed to slide along the limiting groove 22 on the inner side of the fixing plate 21. At the same time, the knocking block 23 squeezes the vibration spring 24 to knock the outer shell of the crushing box 2. When the second cam 20 stops contacting with the knocking block 23, under the elastic force of the vibration spring 24, it knocks back and forth, which can improve the knocking effect, avoid clogging of the filter iron net 7, and can stably crush garbage.

[0042] Embodiment 3: Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.10 The technical solution shown, in order to solve the problem of easy blockage when the humid gas is discharged from the inside of the device, discloses: a threaded rod 28 is rotatably installed inside the drying box 1, and a cleaning and ventilation mechanism is provided on the surface of the threaded rod 28, and the cleaning and ventilation mechanism is provided with a movable block 29, and the movable block 29 is threadedly connected with the threaded rod 28, the middle end of the driving rod 10 is connected with the adjusting rod 26 through the second bevel gear set 25, and the adjusting rod 26 is rotatably installed on the right side of the drying box 1, and the rear end of the adjusting rod 26 is meshed with the rack 27 through a gear, and the middle end of the rack 27 is meshed with the threaded rod 28 through a gear, and a limiting rod 30 is installed through the bottom of the movable block 29, and the front and rear ends of the limiting rod 30 are fixedly installed on the inner wall of the drying box 1, a pressure spring 31 is fixedly installed on the outer side of the movable block 29, and a cleaning brush 32 is fixedly installed on the outer side of the pressure spring 31, and the outer side of the cleaning brush 32 is arranged to fit the inner wall of the air outlet 8, and the outer side of the cleaning brush 32 is inclined;

[0043] In the embodiment, when the driving rod 10 rotates, the adjusting rod 26 is driven to rotate through the second bevel gear set 25. The rear end of the adjusting rod 26 drives the rack 27 to work through the gear. When the rack 27 is working, it drives the threaded rod 28 to rotate through the gear. When the threaded rod 28 rotates, it drives the movable block 29 threadedly connected to its surface. The movable block 29 can move back and forth under the limit of the limit rod 30. As the movable block 29 moves back and forth, the pressure spring 31 inside it applies pressure to the cleaning brush 32, and the cleaning brush 32 is aligned with the surface of the air outlet 8 for cleaning, so as to avoid blockage of the air outlet 8 when the garbage is dried. The practicability of the device can be improved, and the need for manual cleaning after the device is blocked can be avoided.
