Automatic feeding reaction kettle for producing liquid barium-zinc heat stabilizer

Abstract

The invention discloses an automatic feeding reaction kettle for producing a liquid barium-zinc heat stabilizer. The automatic feeding reaction kettle comprises a shell and a mixing device, wherein the mixing device comprises a mixing shaft and a blade; the blade is fixedly arranged on the mixing shaft; the mixing shaft extends into the shell; the shell is divided into four layers, which are a top layer, an upper middle layer, a lower middle layer and a bottom layer separately; the mixing shaft penetrates through the top layer, the upper middle layer, the lower middle layer and the bottom layer; a feeding hole is formed in each layer; the feeding holes are connected with delivery pipes; the delivery pipe connected with the feeding hole in the top layer is connected with a water suction pump; one end of the delivery pipes connected with the feeding hole in the upper middle layer is connected with the water suction pump and the other one is connected with a blast blower; the delivery pipe connected with the feeding hole in the lower middle layer is connected with the blast blower; the delivery pipe connected with the feeding hole in the bottom layer is connected with the blast blower. The automatic feeding reaction kettle for producing the liquid barium-zinc heat stabilizer is capable of automatically feeding, and is simple in feeding, time-saving and labor-saving, and the production efficiency is improved.

Description

technical field [0001] The invention relates to equipment used in the production of a liquid barium-zinc heat stabilizer, in particular to a used reaction kettle. Background technique [0002] Liquid barium zinc heat stabilizer can increase the stability of solutions, colloids, solids, and mixtures. It can slow down reactions, maintain chemical balance, reduce surface tension, and prevent light, thermal decomposition, or oxidative decomposition. Liquid barium zinc heat stabilizers have different properties due to their different compositions. However, it is generally light yellow to yellow clear liquid, with a specific gravity of 0.95-1.02 at room temperature, a viscosity of less than 100 centipoise, and a freezing point of about -15°C. Similar to liquid barium zinc, it has excellent thermal and light stability, low initial coloration, good transparency and color stability. The importance of liquid barium-zinc heat stabilizers is increasing day by day. At present, there ar...
