Zinc sulfate preparation reaction kettle for optical infrared imaging

Abstract

The invention discloses a zinc sulfate preparation reaction kettle for optical infrared imaging. The zinc sulfate preparation reaction kettle comprises a kettle body, a mixing shaft rotationally arranged on the kettle body, and a motor used for driving the mixing shaft to rotate, wherein polytetrafluoroethylene coatings are arranged on the inner wall of the kettle body and the outer surface of the mixing shaft, the kettle body comprises a kettle top, a kettle body and a kettle bottom, the kettle bottom is provided with a zinc sulfate discharging pipe, a sulfuric acid adding pipe is arranged at one side of the kettle top, an outlet end of the sulfuric acid adding pipe extends into the kettle body and is clung to the inner wall of the kettle body, the liquid discharging direction of the sulfuric acid adding pipe is tangent to the inner wall of the kettle body, a zinc oxide adding hole is formed in the other side of the kettle top, a feeding hopper is formed in the zinc oxide adding hole, and the feeding hopper is connected with a zinc oxide conveying device. According to the zinc sulfate preparation reaction kettle, sulfuric acid is not splashed when being added, and meanwhile, zinc oxide is conveniently added.

Description

technical field [0001] The invention relates to a reaction kettle, in particular to a reaction kettle for preparing zinc sulfate for optical infrared imaging. Background technique [0002] At present, the market application of zinc sulfide continues to expand, especially in the field of infrared imaging. Infrared imaging technology has the advantages of long working distance, strong anti-interference, strong ability to penetrate smoke, dust, and haze, and can work all-weather and all-day. A wide range of applications, zinc sulfide as a basic material, has a wide range of needs in the field of infrared imaging technology. However, in the production process of zinc sulfide, it is necessary to react zinc oxide and sulfuric acid to obtain zinc sulfate as the raw material for zinc sulfide, while zinc oxide is packed in powder form, and the current reactor is inconvenient to feed. Generally, the top of the reactor is opened, and at the same time Sulfuric acid is prone to sputter...

However, in the production process of zinc sulfide, it is necessary to react zinc oxide and sulfuric acid to obtain zinc sulfate as the raw material for zinc sulfide, while zinc oxide is packed in powder form, and the current reactor is inconvenient to feed. Generally, the top of the reactor is opened, and at the same time Sulfuric acid is prone to sputtering when it enters the reactor, so there are certain safety hazards
