Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recovery, in particular to a wastewater recovery device for the production of hydroxypropyl methylcellulose. Background Art

[0002] Hydroxypropyl methylcellulose, also known as hydroxypropyl methylcellulose, is a type of non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer. It is often used as a lubricant in ophthalmology, or as an excipient or excipient in oral drugs. It is commonly found in various types of commodities. As a food additive, hydroxypropyl methylcellulose can play the following roles: emulsifier, thickener, suspending agent and substitute for animal gelatin. In the process of recycling wastewater from the production of hydroxypropyl methylcellulose, a large amount of wastewater will be generated. The wastewater is easy to pollute the environment, resulting in a low environmental protection level. Therefore, it is necessary to use a hydroxypropyl methylcellulose production wastewater recycling and treatment device to treat it and discharge it in compliance with the standards.

[0003] Most of the existing wastewater recovery devices use a detachable filter screen for recycling after filtration. Although the filtering and recycling effect is achieved, foreign matter in the wastewater is easily blocked at the mesh opening of the filter screen, which reduces the wastewater recovery efficiency. In addition, the cleanliness achieved by recycling the wastewater that only relies on filtering treatment is still at a relatively low index, further reducing the effect of wastewater recycling treatment.
