Description

Technical Field

[0001] The present invention relates to the field of ethanol preparation, and in particular to a system and method for preparing ethanol based on biomass raw materials. Background Art

[0002] As society pays more attention to environmental protection, traditional fossil energy has caused greenhouse effects due to combustion, which harms human health and the earth's ecosystem. Therefore, biomass resources have once again become an energy source due to their renewability and carbon neutrality. In the process of ethanol production, various food crops are usually used as raw materials to produce ethanol, such as various tuber crops including sweet potatoes, potatoes and cassava.

[0003] Among the raw materials used in the traditional method of preparing ethanol, most of the raw materials are crops, such as sweet potatoes, corn, sorghum and cassava. These crops are inevitably mixed with debris when picked in the fields. For example, sweet potatoes are buried in the soil when they are planted. When they are picked, it is inevitable that there will be fine sand, large stones or broken strips of plastic cloth or woven bags and other plastic product residues.

[0004] During the sweet potato picking process, since the surface of the sweet potato is covered with plastic film when it is planted, although the film will be removed before picking, it is impossible to ensure that there will be no tearing residue in the process of removing the film. In mechanized picking, the residual film will be mixed with the sweet potato; in the ethanol preparation process, the raw materials will also be screened before entering the crushing process to screen out the sand, soil and stones in the sweet potato. Most of the current screening methods use shaking screens to screen out impurities and sand. Although the purpose of screening can be achieved, the plastic film in the raw material picking process and the residual lint in the woven bags used to hold the sweet potatoes cannot be cleaned by shaking screens. After a period of time, the debris crushed along with the raw materials is easy to accumulate in the subsequent transportation process, causing blockage. Therefore, cleaning is required. Based on this, we propose an ethanol preparation system and method based on biomass raw materials. Summary of the invention

[0005] In order to solve the technical problem that plastic films in the process of picking crop raw materials and residual lint in woven bags for sweet potatoes cannot be cleaned by shaking screens, the present invention provides an ethanol preparation system and method based on biomass raw materials.

[0006] The present invention is implemented by the following technical scheme: a method for preparing ethanol based on biomass raw materials, the method for preparing ethanol comprising the following steps: S1: Collecting raw materials for preparing ethanol, including sweet potato, cassava and sorghum; S2: Transporting and cleaning raw materials: transporting the crop raw materials for preparing ethanol, and cleaning them to remove soil impurities on the surface of the crops; S3: Raw material crushing: crushing the cleaned crop raw materials, and making the crushed raw materials into slurry; S4: enzymatic hydrolysis of raw materials: enzymatic hydrolysis of the slurry obtained after the raw materials are crushed, and the enzymatically hydrolyzed slurry is fermented to finally produce ethanol.

[0007] As a further improvement of the above scheme, a system is applied to the method for preparing ethanol based on biomass raw materials as described in claim 1, wherein the equipment for cleaning the ethanol preparation raw materials in S2 includes a preparation system body, and the preparation system body includes a sand and gravel vibration shaking screen mechanism, a linkage receiving mechanism, a plastic film collecting mechanism and a film shedding mechanism.

A moving bracket rod is installed below the bracket block, and a connecting bracket component is connected to the outer side of the moving bracket rod.

[0011] The plastic film collecting mechanism comprises a mounting frame, a sliding block is mounted on the inner side of the mounting frame, one end of the sliding block is mounted on the mounting frame, and the other end is clamped and limited in a slide groove opened on the surface of the inner frame, and the sliding block slides on the inner side of the slide groove.

[0012] The outer side of the mounting frame is connected with a connecting rack, the lower side of the connecting rack is meshed with a connecting gear, the moving shaft rod passes through the connecting gear, the surface of the moving shaft rod is sleeved with a fixed shaft sleeve for limiting, the top of the moving shaft rod is connected with a first bevel gear, the outer side of the first bevel gear is meshed with a second bevel gear, and the inner side of the second bevel gear is connected with a winding roller.

[0016] As a further improvement of the above scheme, the winding roller is driven to rotate by the second bevel gear. The winding roller then moves back and forth and rotates on its own.

The two groups of mechanisms work synchronously and only require one set of power source. While the sand and gravel vibration screening mechanism is oscillating, the plastic film collection mechanism also works synchronously to ensure the continuity of the work.

[0019] 2. The present invention innovatively proposes a film shedding mechanism, in which the winding rod can wind and collect the plastic film. At the same time, the winding rod can also shrink, and the winding rod rubs against the shedding cavity to remove the plastic film wrapped around the surface of the winding rod, thereby preventing the winding rod from being wrapped with excessive plastic film on the surface and being unable to work continuously.
