Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] see Figure 1 to Figure 2 , a pre-treatment system for the environmental protection process of secondary utilization of plant branches and leaves, including a processing machine room 1, a crushing assembly 5, a main crushing shaft 7, a screening pipeline 3 and a discharge pipeline 4, and the inside of the processing machine room 1 is provided with a crushing assembly 5. There is a main crushing shaft 7 passing through the middle of the crushing assembly 5. The top and bottom ends of the main crushing shaft 7 are respectively connected to the middle of the upper drive bearing 73 and the lower fixed bearing 74. The bottom of the processing machine room 1 is screened through the pipeline. 3 is communicated with the discharge pipe 4;

Abstract
A pre-treatment system for the environmental protection process of secondary utilization of plant branches and leaves. The main crushing shaft drives the upper crushing plate, the lower crushing plate, the heating frame, and the outer crushing hook to destroy and crush the straw to be treated in the processing machine room to reduce the volume of the straw , and improve the mixing uniformity of straw and humidity. The outer crushing hook includes the hook axis, the hook ball head and the outside of the hook. The outside of the hook includes vertical strips, upper horizontal strips and lower horizontal strips. The heating wire set in the heating frame can provide an additional heat source, and the temperature sensor can monitor the temperature in the processing room to ensure the crushing effect. This design not only has a strong stirring function, but also has a good crushing effect, can provide an additional heat source, and has high filtration efficiency, strong controllability, which is beneficial to subsequent fermentation, and has better environmental protection.
Description
technical field [0001] The invention relates to a recycling process of discarded plant branches and leaves, which belongs to the field of environmental protection, and in particular to a pretreatment system for the environmental protection process of secondary utilization of plant branches and leaves, which is specifically suitable for improving the crushing effect and facilitating subsequent fermentation. Background technique [0002] Biogas fermentation, also known as anaerobic digestion or anaerobic fermentation, refers to organic matter, such as human, livestock and poultry manure, straw, weeds, rice husk, wheat husk, bean husk, etc. The process of catabolism and the final formation of flammable mixed gases such as methane and carbon monoxide, which is biogas. Since most of its raw materials come from straws of crops such as wheat, corn, peanuts, and soybeans, as well as the shells of wheat, rice, peanuts, melon seeds, and beans, it is regarded as a highly environmentall...
