Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid waste treatment, in particular to a pulverizing device for solid waste pretreatment. Background Art
[0002] Solid waste refers to solid waste generated during production, life and other activities. Generally, solid waste has the value of secondary development and utilization, and needs to be processed so that it can be put into use again. Moreover, the treatment of solid waste is an important task of environmental protection. Common treatment methods include recycling, incineration and landfill.

[0030] Through the above structure, the motor 1 6 drives the crushing roller 1 4 to rotate, and the driving gear 7 and the driven gear 8 are engaged to generate relative rotation, so that the crushing roller 1 4 and the crushing roller 2 5 rotate relative to each other, and the input material is crushed, and then sent to the crushing blade 12 driven by the motor 2 16 below through the guide hopper 14 for secondary crushing, and finally screened by the screen 13 so that the material is discharged from different outlets.
[0031] Combined with Figure 2 , Figure 3 and Figure 5 As shown, the crushing roller 1 4 and the crushing roller 2 5 have the same rotation speed and opposite direction, the surface roller teeth of the crushing roller 1 4 and the crushing roller 2 5 are meshed, a guide hopper 14 is fixedly provided between the crushing roller 1 4 and the support frame 1 9, a protective shell 15 is connected to the lower part of the support frame 2 10, a motor 2 16 is fixedly provided on the protective shell 15, and one end of the rotating rod 11 is connected to the output end of the motor 2 16.
[0032] Through the above structure, the crushing roller 1 4 and the crushing roller 2 5 rotate relative to each other at the same speed to achieve the extrusion and crushing operation of the waste. The guide hopper 14 can guide the crushed waste to the crushing blade 12 rotating below, so that the crushing blade 12 can perform secondary crushing on the material.
