Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microbial degradation equipment, and particularly relates to an equipment for treating agricultural film micro-plastics by microbial degradation. BACKGROUND

[0002] At present, main agricultural film treatment methods include landfill, incineration, recycling and the like. In the landfill process, residual pesticides and heavy metals on the agricultural film will pollute groundwater. When the agricultural film is burned, hydrocarbons and derivatives thereof will inevitably be produced. The recycling method needs a high cost and still has agricultural film residues.

[0003] A patent with a publication number CN220635791U discloses a biological degradation plastic device, which comprises a closed box body. A feeding barrel is arranged at the top center of the closed box body. A plurality of mutually matched rolling mills are arranged at the top of the feeding barrel. A crushing mechanism is arranged in the closed box body. A first sliding plate extending to the left side outside of the closed box body is arranged in the closed box body and located at the bottom of the crushing mechanism. A second sliding plate extending to the right side outside of the closed box body is arranged in the closed box body and located at the bottom of the crushing mechanism. A degradation cavity is arranged in the closed box body and located at the bottom of the first sliding plate and the second sliding plate. A microorganism layer is arranged at the bottom of the degradation cavity. A temperature and humidity sensor is arranged on the right side wall of the degradation cavity. A controller electrically connected with the temperature and humidity sensor is fixedly arranged on the right side wall of the closed box body. A heating plate is arranged on the rear side wall of the degradation cavity. A sprayer is arranged on the left side wall of the degradation cavity. A material taking door plate matched with the degradation cavity is hingedly arranged on the front side wall of the closed box body.

[0004] The biological degradation plastic device adjusts the temperature and humidity in the degradation cavity through the temperature and humidity sensor and the controller, improves the degradation efficiency, ensures that the temperature and humidity does not exceed the limited range, reduces the risk of harmful substances, and improves the safety of the device. However, the biological degradation plastic device has some defects, for example, the plastic enters the closed box body through the feeding barrel. At this time, most of the plastic is accumulated at the end of the first sliding plate and the second sliding plate. When the plastic is crushed, the first sliding plate and the second sliding plate move away from each other. The plastic on the top surface of the first sliding plate and the second sliding plate is pushed down by the discharging push plate. During the falling process of the plastic, most of the plastic falls in the middle part of the microorganism layer, and a small part of the plastic falls at the edge of the biological layer. The plastic is accumulated at a certain position of the microorganism layer, which affects the efficiency of the biological degradation of the plastic, and needs to be improved. UTILITY MODEL CONTENT

[0005] The present application aims to provide an equipment for treating agricultural film micro-plastics by microbial degradation, so as to reduce the accumulation of plastic.

[0006] The application provides a device for degrading agricultural film microplastics by microorganisms, which adopts the following technical scheme:

[0007] The box is provided with a feed inlet, and a crushing mechanism, a blocking mechanism and a microbial layer are connected in the box.

[0022] By adopting the technical scheme, the rotating assembly drives the two rotating rods to rotate, that is, the baffle rotates around the axis of the corresponding rotating rod, so that the plastic on the baffle falls on the microbial layer from different directions, improving the effect of dispersing the plastic on the microbial layer.
