Description

Technical Field

[0001] The present application relates to a filtering device for producing liquid ground film. Background Art

[0002] There are two main synthetic directions for liquid mulch. One direction is to use organic matter as the main core, which actually transfers the film-forming process to the soil. The other direction is to use crop straw as the main raw material, and then add synthetic liquid materials such as collagen, surfactants, water retaining agents, and herbicides, and then directly spray it on the soil to form a layer of mulch on the surface of the soil. This kind of mulch can play a role in weeding, water retention, and heat preservation. In the production method of liquid mulch, it is generally necessary to pre-treat the plant straw, ferment it after pre-treatment, and then filter it to obtain the fermentation liquid containing materials such as lignin, which can be used as the primary raw material for liquid mulch. During filtration, due to the complex components of the filtered liquid, the existing filtration device is very easy to clog, and it is difficult to perform continuous filtration, which affects the overall production efficiency.
