A production device for dust-free hydroxypropyl methylcellulose

Abstract

The invention relates to a device for producing hydroxypropyl methyl cellulose in a dustless manner. The device comprises a cotton grasping device, a material crushing device, a draft fan device, a cabin, a weighing module and a production workshop which are connected with one another, wherein a material separation device is connected to the cabin; the material separation device comprises a secondary sedimentation and drying device; the cotton grasping device, the material crushing device, the draft fan device, the cabin, the weighing module, the secondary sedimentation and drying device and the production workshop are connected through pipelines. According to the device for producing the hydroxypropyl methyl cellulose in a dustless manner, from the procedure that a raw material, that is, cotton, is fed into the cotton grasping device to the procedure that the raw material is crushed and packaged, the whole production process adopts pipeline conveying, so that dustless production is achieved; and moreover as equipment such as the cotton grasping device, the secondary sedimentation and drying device, the material crushing device and the weighing device achieves automation, the production efficiency is improved, and the product quality is also improved.

Description

technical field [0001] The invention relates to a production device of hydroxypropyl methylcellulose, in particular to a production device of dust-free hydroxypropyl methylcellulose. Background technique [0002] In the production process of hydroxypropyl methylcellulose, it needs to go through processes such as cotton crushing, reaction, sedimentation drying and material crushing. The existing equipment only transports the broken cotton to the reactor for reaction after crushing once, but because the particle size of cotton is too large, it is easy to cause incomplete reaction, which leads to waste of raw materials and difficulty in cleaning waste. After the reaction, the material needs to be settled and dried. The traditional production equipment separates the settling and drying process, that is, the settling is carried out first, and then the settled material is sent to the drying equipment. This process requires a settling device and a special drying device. Equipment ...

AI Technical Summary

Problems solved by technology

The blanking mechanism in the traditional material crushing device is a single-channel blanking, and the amount of material that can be dropped at one time is small, and when the material is discharged, the dust cannot be effectively recovered, which does not meet the requirements of environmental protection

Therefore, the production efficiency of the material crushing device of the single-channel blanking mechanism is very low, and the dust cannot be effectively recovered, which does not meet the requirements of environmental protection; the traditional dust collector is either unsatisfactory in dust removal effect or expensive, which is not suitable for the material crushing device. a best of both worlds

The most important thing is that in the traditional hydroxypropyl methylcellulose production equipment, each step needs manual handling to complete. Due to the particularity of raw cotton, the dust is very large, which not only has an adverse impact on the environment, but also hardens the operator. good health
