Abstract

The utility model relates to a chemical oxygen generator capable of controlling oxygen-generating speed, which is composed of a reaction chamber, a gas washing chamber, an oxygen-generating agent bin, a mechanical conveying system, a clock circuit, a gas-liquid separator, etc. The output pulse width of the clock circuit is regulated to control the rotating and the stopping time period of a motor so that solid oxygen-generating agent is quantitatively conveyed to the reaction chamber by a mechanical conveyer in the oxygen-generating agent bin. According to the set time, the utility model controls the feeding quantity of the oxygen-generating agent so as to uniformly release oxygen so that the oxygen-generating speed is controlled. As a result, the utility model has the advantages of reasonable structure, convenient operation and safe use.

Description

May command is produced the chemical oxygenerator of oxygen speed

The utility model relates to a kind of chemical oxygen generation device.

Before the utility model is made, existing number of chemical method for producing oxygen through and device, wherein major part is with chemical oxygen producing agent, catalyzer and water is disposable to be put into reactor and carries out cartalytic decomposition effect and produce oxygen, this method and apparatus is fairly simple, thereby it is inhomogeneous to exist product oxygen, the deficiency of uncontrollable product oxygen speed.

Chinese patent CN2150197Y discloses the purpose that has realized control product oxygen speed with the contact area of regulating the fixed catalytic network and the oxygen producing agent aqueous solution, but because said apparatus only is suitable for producing oxygen from hydrogen peroxide, inapplicable to other solid peroxide, range of application is narrower, and on the other hand, hydrogen peroxide is a highly corrosive agents, careless slightly in the operation will skin ambustion, contain hydrogen peroxide vapor in the oxygen that produces, can damage respiratory mucosa, in daily use, exist danger without fully purifying.

The purpose of this utility model is the deficiency that will overcome in the present technology, and an applied range is provided, and is safe and reliable, can regulate the chemical oxygenerator that produces oxygen speed continuously.

Goal of the invention of the present utility model is achieved by the following scheme: this chemical oxygenerator is made up of upper box (6) and lower box (9) two portions, chamber (10) responds in the lower box (9), gas washing chamber (11), airway (12), an end of mechanical conveyor (3) is the discharge gate (4) of oxygen producing agent in the upper box (6), the intermediary opening for feed is connected with the outlet of oxygen producing agent feed bin (1) below, and the deceleration device that the other end is formed by turbine (14) scroll bar (13) links to each other with electric motor.

Clock circuit described in the utility model (5) is controlled the rotation of electric motor (8) and is stopped, and regulates the pulse width of clock circuit (5) output, thus the time cycle that control electric motor (8) rotates and stops.

Gas-liquid separator described in the utility model (18) bottom is a porous gas-liquid separation plate (15), the gac (16) of adsorptive catalyst powder is placed by lower floor, upper strata placing porous foam layer (17), top are provided with oxygen (19) outlet, and gas-liquid separator (18) uses screw thread to be connected with upper box.

Mechanical conveyor described in the utility model (3) can be selected worm conveyor for use, scraper conveyor, rotary conveyor, disc conveyor, any in the tipping bucket transfer roller.

Deceleration device described in the utility model can use turbine worm to slow down, and gear unit slows down, any in the pulley decelerates.

Solid oxygen producing agent described in the utility model is a SPC-D, and superoxide such as Sodium peroxoborate quantitatively are transported to reaction chamber (10) by oxygen producing agent feed bin (1) by mechanical conveyor (3), catalyzer is a manganese, cobalt, the oxide compound of iron, during use, after adding entry, directly drops into reaction chamber (10).

The utility model is described in more detail below in conjunction with accompanying drawing and specific embodiments:

Fig. 1 is the structural representation that the may command that the utility model proposes is produced the chemical oxygen generator of oxygen speed.

The clocking scheme that Fig. 2 is made up of 555 unicircuit.

Fig. 3 is the oscillogram of 555 ic output A.

In Fig. 1, by charge door (21) the solid regenerative agent is joined in the regenerative agent feed bin (1), by with the end opening phase The mechanical conveyor (3) that connects is pushed to discharge gate (4), drops in the reative cell (10), and is placed in advance reative cell (10) Emit oxygen under the effect of the catalyst in the water, oxygen enters gas washing chamber (11) through wireway (12), behind the gas washing Oxygen contacts the catalysis of activated carbon surface with the activated carbon that is loaded with catalyst fines (16) in gas-liquid separator (18) The impurity that carries in the agent adsorption of oxygen, after catalytic reaction again, oxygen is purified, again through upper strata porous foam layer (17) can become pure oxygen and discharge from oxygen outlet (19), feed bin lid (20) uses screw thread and upper box (6) to revolve Tightly, prevent that oxygen from leaking from charge door 1 (21), sealing gasket (7) makes upper box (6) be connected 9 with lower box) connect closely.

The clocking scheme that Fig. 2 is made up of 555 integrated circuits, the resistance value of change variable resistor (2) just can Change the time cycle (seeing Fig. 3) of 555 ic output A end T2, thereby change motor (8) stops fortune The time of turning to, just controlled the inventory that enters into reative cell (10) regenerative agent.

Embodiment 1: use device shown in Figure 1, reaction chamber (10) and gas washing chamber (11) are injected clear water, put into catalyzer 5g earlier at reaction chamber (10), the 100g SPC-D is put into oxygen producing agent feed bin (1), adjusting the middle variable resistor (2) of clock circuit (5) makes electric motor (8) to rotate the period run that stopped in 3 seconds 15 seconds, per minute produces oxygen 200ml, oxygen supply time 40 minutes.Be applicable to daily health caring.

Embodiment 2: use device shown in Figure 1, reaction chamber (10) and gas washing chamber (11) are injected clear water, put into catalyzer 5g earlier at reaction chamber (10), the 100g SPC-D is put into oxygen producing agent feed bin (1), adjusting the middle variable resistor (2) of clock circuit (5) makes electric motor (8) to rotate the period run that stopped in 3 seconds 7 seconds, per minute produces oxygen 400ml, and oxygen supply time 20 minutes is applicable to heavier anoxic symptom.
