Description

Technical Field

[0001] The utility model relates to the technical field of furfural production, and more specifically to a reciprocating crusher for furfural production. Background Art

[0002] Furfural is an important organic compound with the chemical formula C5H4O2. It is a colorless, transparent, oily liquid with a special smell similar to benzaldehyde. It is mainly used as an industrial solvent and can also be used to produce furfuryl alcohol, furoic acid, tetrahydrofuran, γ-valerolactone, pyrrole, tetrahydropyrrole, etc. The raw materials for the production of furfural mainly come from the husks, straws and wastes of grains such as rice, corn, wheat and other crops. These raw materials can be properly treated and processed to obtain high-quality furfural products.

[0003] At present, in the process of furfural production, the crushing of raw materials is a crucial step. However, in the existing technology, most crushers process furfural raw materials by crushing them once. This one-time crushing method has many shortcomings, which seriously restricts the efficiency and effect of furfural production. First, one-time crushing often cannot fully refine the particle size of the raw materials. Due to the limitations of crushing strength and time, there are still large particles in the raw materials. When these particles are hydrolyzed with water, the reaction area is limited, resulting in insufficient reaction and low furfural extraction efficiency. This not only affects the output of the final product, but also may lead to unstable product quality; secondly, when the raw materials after one crushing are hydrolyzed with water, the reaction speed will also be affected due to uneven particle size. Large particle raw materials react slowly, while small particle raw materials may cause local overheating or agglomeration due to excessive reaction, further affecting the extraction effect of furfural. Such a result not only reduces production efficiency, but also increases energy consumption and material consumption in the production process; in addition, the low crushing efficiency of one crushing also means that a longer shutdown is required for raw material loading and equipment cleaning, which undoubtedly increases labor costs and production cycles. At the same time, the consumption of raw materials is also high, which not only increases production costs, but may also affect the continuous operation of the production line due to insufficient raw materials.
