[0002] Neopentyl glycol is an important chemical raw material and solvent, widely used as an additive or intermediate in coatings, inks, pharmaceuticals and plastics industries.

[0003] During the production process, due to incomplete reaction, a portion of the neopentyl glycol raw material is often not converted into products and remains on the inner wall of the reactor. At this time, the inner wall of the reactor needs to be cleaned manually, but the reactor is generally large in size, and manual cleaning is very inconvenient.

[0004] For this reason, a neopentyl glycol raw material recovery system is proposed. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a neopentyl glycol raw material recovery system, which solves the problem of the troublesome manual cleaning of the inner wall of the reactor.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

With the coordinated use of the rotating plate and the mounting frame tooth block, the gear can be rotated between the rotating plate and the mounting frame, so that the cleaning roller can rotate in the reactor to clean the inner wall of the reactor. Compared with manual cleaning of the inner wall of the reactor, the present application can better clean the inner wall of the reactor after the neopentyl glycol raw material reacts, thereby avoiding the neopentyl glycol raw material from remaining on the inner wall of the reactor without being converted into products, causing unnecessary waste.

[0016] 2. The neopentyl glycol raw material recovery system can send the materials cleaned by the cleaning component into the solid-liquid separation component through the recovery pipe, and then separate the materials into solid and liquid through the solid-liquid separation component, so as to facilitate the staff to handle the materials later. Through the solid-liquid separation plate at the bottom of the filter barrel, the solid material can be left in the filter barrel, and the liquid material can flow into the bottom of the fixed separation box to complete the solid-liquid separation, which is convenient for the staff to handle the materials according to the conditions. Moreover, the liquid level in the solid-liquid separation box can be monitored through the floating plate and the touch switch. When there is more liquid in the solid-liquid separation box, the floating plate is easy to touch the touch switch, so that the alarm will sound to remind the staff to come and check, so as to avoid excessive liquid in the solid-liquid separation box and leakage.
