Technical Field

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

[0002] Before pyrolysis of municipal solid waste, it is necessary to crush the waste. However, municipal solid waste (especially kitchen waste) has high moisture content and high viscosity, which can easily lead to clogging, low efficiency and poor crushing effect of traditional crushers. The actions of each link in the municipal solid waste treatment are not connected and rely on manual coordination, resulting in low efficiency and a lack of smoothness in the overall treatment process. Therefore, a crushing device for municipal solid waste pyrolysis is proposed. Utility Model Content

Multiple first crushing wheels 13 are rotatably connected inside the crushing and conveying box 3, and the first crushing wheels 13 are connected to the first gear reducers 12. The first crushing wheels 13 are used to crush household waste. Two third support frames 14 are fixedly connected to the crushing and conveying box 3, on which third drive motors 15 are fixedly installed. The second gear reducer 16 is connected to the third drive motor 15. Two second crushing wheels 17 are rotatably connected inside the crushing and conveying box 3, and are connected to the second gear reducer 16. The second crushing wheels 17 are used for secondary crushing of domestic waste. A slide rail frame 18 is fixedly connected to the fixed base plate 1. A distance sensor 19 is installed on the slide rail frame 18. Two electric push rods 20 are fixedly installed on the slide rail frame 18. A connecting rod 21 is connected to the telescopic rod of the electric push rods 20. A conveyor 22 is slidably connected to the slide rail frame 18 and is connected to the connecting rod 21. The conveyor 22 has a groove and is equipped with... Pressure sensor 23 is used to detect the weight of domestic waste. A carrying box 24 is placed on the conveyor 22. A fixed column 25 is fixedly connected to the crushing and conveying box 3. A fourth support frame 26 is fixedly connected to the crushing and conveying box 3. A fourth drive motor 27 is fixedly installed on the fourth support frame 26. A second rotating shaft 28 is connected to the output shaft of the fourth drive motor 27. The second rotating shaft 28 is rotatably connected to the fixed column 25. A filter frame 29 is rotatably connected to the crushing and conveying box 3. The filter frame 29 is connected to the second rotating shaft 28. Multiple holes are opened on the filter frame 29. A dryer 30 is fixedly installed on the crushing and conveying box 3.

[0025] The transport vehicle 22 consists of a transport platform and moving wheels.

[0026] A handle is fixedly connected to the carrier box 24.

[0027] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is smaller than the value of the second threshold.

[0028] Pour a small amount of household waste into the filter box, press the drying button to control the dryer to work. The hot air generated by the dryer blows onto the filter box, thereby improving the dryness of the household waste and preventing it from being too wet and affecting the crushing efficiency. After the household waste is dry, press the drying button again to stop the dryer from working.

[0029] The system controls the first drive motor to rotate the first shaft, the first conveyor wheel, the second conveyor wheel, and the conveyor belt. The second drive motor and the first gear reducer drive the first crushing wheel to rotate. The third drive motor, the second gear reducer, and the second crushing wheel rotate. Then, the system controls the fourth drive motor to rotate the second shaft and the filter frame. When the filter frame flips, the household waste is dumped onto the conveyor belt, which transports the waste into the crushing and conveying box. The first crushing wheel crushes the waste, and the crushed waste falls onto the second crushing wheel, which continues to crush it. Finally, the crushed waste falls from the crushing and conveying box onto the carrying box, thus completing the collection of household waste.

[0030] When the weight of the household waste in the container reaches the preset threshold of the pressure sensor, the first, second, and third drive motors stop working. At the same time, the electric push rod moves the connecting rod, the conveyor, and the container. When the distance between the conveyor and the distance sensor reaches the first preset threshold of the distance sensor, the electric push rod stops working. Then, the container filled with household waste is removed from the conveyor. Next, the empty container is placed on the conveyor. Pressing the reset button controls the electric push rod to move the connecting rod, the conveyor, and the container in the opposite direction. When the distance between the conveyor and the distance sensor reaches the second preset threshold of the distance sensor, the electric push rod stops working, so that the container is located below the crushing and conveying box.

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.
