[0037] The method for preparing slurry provided by the present invention includes:

[0038] Using the feeding device 100 to supply raw materials, the raw materials include small particle size raw materials and large particle size raw materials, the small particle size raw materials are doped with fine impurities, and the large particle size raw materials are doped with light impurities;

[0039] Classification process: classify the supplied raw materials into small particle size raw materials and large particle size raw materials, wherein the small particle size raw materials are usually doped with fine impurities, and the large particle size raw materials are usually doped with light impurities thing;

[0040] Sand settling process: carry out sand settling treatment on the small particle size raw materials doped with fine impurities, wherein the density of the fine impurities is greater than the density of water, and the sand settling treatment includes: making the doped fine...

Embodiment approach

[0053] According to the first specific embodiment of the present invention, as figure 2 As shown, an open space capable of accommodating materials should be formed between two adjacent box plates 3000 and the transmission chain 2000 to meet the needs of accommodating and transporting materials; Figure 5 As shown, the included angle (β) between the plane of the box plate 3000 between the axes of the drive rollers 1000 and the plane of the transmission chain 2000 can be 30°-90°, preferably 60°-90°; The second specific implementation, such as Figure 5 As shown, an open space capable of accommodating materials should be formed between two adjacent box boards 3000 and the base member 6000 to meet the needs of accommodating and transporting materials; The included angle (β) between the plane where the plate 3000 is located and the plane where the base member 6000 is located may be 30°-90°, preferably 60°-90°.

Abstract

A method for preparing slurry comprises the following steps of: supplying raw materials; classifying the supplied raw materials into raw materials with small particle size and raw materials with large particle size; carrying out desanding processing on the fine foreign material-doped raw materials with small particle size; conveying lightweight foreign material-doped raw materials with large particle size along a conveying line, and removing impurities; and preparing the slurry by the use of a serous fluid mixed with the small-particle sized raw materials and the crushed raw materials with large particle size. The method provided by the invention can be used to improve the material supply efficiency and effectively remove foreign materials in the raw materials.

Description

technical field [0001] The present invention relates to the field of chemical industry, and more particularly, to a method for preparing slurry for ethanol production. Background technique [0002] In various occasions of industrial application, the preparation of slurry is often required. For example, in a factory for producing ethanol, the usual process is: firstly, the raw material (such as block, flake or granular cassava, sweet potato, potato, etc.) is transported to the pulverizing device through the feeding device, and then the pulverizing device The larger raw materials are pulverized into smaller or finer raw materials, and then the water and the finer raw materials are mixed by a pulping device to form a slurry, and then the obtained slurry is subjected to enzymatic hydrolysis and fermentation treatment, and finally obtained Ethanol. [0003] In this traditional process, the conveyed raw materials are inevitably mixed with impurities, such as finer sand, larger s...
