The vacuum feeding machine for reaction vessels produced by Dongguan Tiantian Automation adopts new processes and technologies, effectively solving the problem of dust flying from the feeding port, organic solvents overflowing from the feeding port, and pungent odors in the workshop when manually feeding into the reaction vessel. The closed vacuum feeding machine for the reaction kettle operates automatically, with automatic suction, discharge, and blowback without the need for personnel supervision, reducing the labor intensity of employees. The equipment is connected to the feeding port of the reaction kettle in a sealed soft connection, which is easy to remove and install, and convenient to operate. The material enters the vacuum feeding machine compartment through a pipeline, and then falls into the reaction kettle through the discharge material. Through nitrogen back blowing, the pressure difference is balanced to accelerate the material falling, and the material attached to the outside of the gas-solid separator can be blown off. After the discharge is completed, the suction and discharge are carried out in a cyclic manner.

　　

The control part of the closed vacuum feeding equipment for the reaction kettle is controlled by PLC, and programs are written according to the production requirements of the workshop process to meet the production needs of the workshop. The equipment accepts non-standard production from customers and is made according to specific spaces to meet production needs. The control part can be connected to the workshop DCS control system for unified monitoring and start stop of equipment from the control room. The equipment can achieve intermittent feeding, such as automatic stop after running for 5 minutes, automatic start after stopping for 15 minutes, and feeding after running for 5 minutes. The running time and stop time can be set freely. The operation of the equipment is automatically controlled through temperature control or material level height interlocking by the DCS control system.

　　

The application of closed vacuum feeding equipment for reaction kettle chemical feeding greatly reduces the labor intensity of employees and improves the working environment in the workshop; Applied to centrifuges for drying, it eliminates the generation of falling particles during manual transportation of materials, reduces dust falling particles during material pipeline transportation, increases the yield of powder materials, and connects the tail gas to the recovery tower for recycling or treatment, improving the odor problem during manual transportation of materials; Applied to the closed conveying of materials from drying to vibrating screens, reducing workshop dust and improving the working environment in the workshop.

Install a vacuum feeding system on the reaction vessel, which includes a vacuum pump Vacuum tube and feeding tube, open vacuum port and feeding port on the reaction kettle, connect the vacuum pump through the vacuum tube on the vacuum port, and install the feeding tube on the feeding port When working, the material bucket is placed on the ground, the feeding tube is inserted into the bucket, the vacuum pump is turned on, and when a certain degree of vacuum is reached in the reaction kettle, the material in the bucket is automatically added to the reaction kettle through the feeding tube This system has a simple structure, low cost, easy operation, automatic feeding, time-saving, light labor intensity for workers, and high work efficiency
