Chemical oxygen generating device

Abstract

The invention discloses a chemical oxygen generating device. The chemical oxygen generating device comprises a box. A reaction cavity is formed inside the box, a liquid level sensor is arranged on the inner all of the reaction cavity, a discharging opening is formed in the bottom of the box, a first electromagnetic valve is arranged on the discharging opening, an oxygen outlet is formed in the top of the box, a second electromagnetic valve is arranged on the oxygen outlet, and an air pressure gauge is arranged on one side of the oxygen outlet. According to the chemical oxygen generating device, hydrogen peroxide is injected through a feeding opening, pistons are pulled through electric stretchable rods, and the hydrogen peroxide is sucked into piston cylinders and stored, and then is put into a reagent pipe filled with manganese dioxide through the feeding opening; when oxygen needs to be generated, the electric stretchable rods push the pistons to inject the hydrogen peroxide into the reaction cavity, and the hydrogen peroxide is reacted with the manganese dioxide in the reagent pipe; meanwhile, the electric stretchable rods are matched with the pistons, the liquid level height of the hydrogen peroxide in the reaction cavity is changed, the contact area between the hydrogen peroxide and manganese dioxide is changed accordingly, and the oxygen generating rate of the whole device is controlled.

Description

technical field [0001] The invention relates to the technical field of chemical oxygen production, in particular to a chemical oxygen production device. Background technique [0002] Oxygen production is a relatively important experiment in chemical experiments. In the process of oxygen production, temperature, pressure, concentration, and the amount of reaction liquid all have a direct impact on the results of oxygen production. Most of the current chemical oxygen production devices are relatively simple. , in the process of oxygen production, hydrogen peroxide reacts with manganese dioxide, and the rate of generating oxygen is directly related to the concentration of hydrogen peroxide and the contact area between hydrogen peroxide and manganese dioxide. However, the traditional oxygen production method cannot control the oxygen generation rate. For this reason, we propose a kind of chemical oxygen generator.
