Description

Splash-proof auxiliary material injection device Technical Field The utility model relates to an anti-splashing auxiliary material injection device. Background The continuous production polyester chemical fiber device is widely applied in conventional production operation, the most common is a five-kettle reactor polymerization device, and most polymerization reactors are micro-positive pressure or negative pressure equipment. At present, various raw and auxiliary materials are required to be added into a reactor of a polymerization chemical fiber device, and the raw and auxiliary materials are injected into the reactor through a nozzle (a conveying pipe), specifically, one end of the nozzle extends into the reactor, the other end of the nozzle is positioned outside the reactor and is communicated with a raw and auxiliary material supply source, and the raw and auxiliary material supply source conveys the raw and auxiliary materials to the nozzle, so that the problems are that: 1. The reactor belongs to a continuous production device, the raw materials and the auxiliary materials are added in the production process, and the raw materials and the auxiliary materials are only uninterruptedly injected in the reactor in a high-temperature micro-positive pressure state, and once the raw materials and the auxiliary materials are interrupted, the materials in the reactor can flow back into the nozzle, solidify to block the nozzle, so that the auxiliary materials cannot be injected into the reactor again, namely cannot be intermittently injected; 2. In order to uniformly mix the injected raw materials and auxiliary materials with the materials in the reactor, the depth of the nozzle in the reactor needs to be adjusted and changed, and when the height is adjusted or the nozzle which cannot be used after blockage is extracted, a high-temperature medium in the reactor can splash, operators are easy to scald, large potential safety hazards exist, and the operation flexibility is poor.
