Description
Technical Field
The invention belongs to a self-rescuer for escape of operators in dangerous environments, and particularly relates to a compressed oxygen self-rescuer for mines.
Background
The currently known mine self-rescuer can be divided into a filtering type self-rescuer, a chemical oxygen self-rescuer and a compressed oxygen self-rescuer according to the principle and the application. The mine compressed oxygen self-rescuer is an oxygen supply self-rescuer with an isolated closed breathing circulation system which fills oxygen into an oxygen bottle in advance through a filling pump, and solves the problem that the respiratory effect is influenced because a filter type self-rescuer cannot be used in severe anoxic and anoxic environments.
The existing mine self-rescuer consists of an upper shell and a lower shell, wherein one side of the lower shell is provided with an oxygen bottle, the other side of the lower shell is designed into a cleaning tank, and the lower opening of the cleaning tank is arranged at the bottom of the lower shell and is used for filling a cleaning agent into a tank body. When the cleaning tank is filled with the cleaning agent, the cover at the bottom of the shell is screwed, and the cover protrudes out of the bottom of the lower shell, so that the stable placement of the compressed oxygen self-rescuer is influenced. In order to solve the problem of stable placement, the bottom of one side of the oxygen cylinder installed on the lower shell is also provided with a simulation cover with the same shape and size. The design has unreasonable factors, and particularly, once the cleaning tank arranged at the bottom of the shell is damaged by external force, the lower shell of the whole compressed oxygen self-rescuer is scrapped. Meanwhile, the medicine adding hole of the existing mine compressed oxygen self-rescuer is usually arranged on one side of the bottom of the cleaning tank, which is far away from the oxygen bottle, the position of the medicine adding hole is just opposite to the expiration pipe in the cleaning tank, and the added medicine is in a strip shape, so that the medicine cannot be conveniently and conveniently added due to the blockage of the expiration pipe during medicine adding. Substances such as dust and the like may exist in the cleaning tank, and may enter a human body along with the breathing of mine workers when in use, so that the health of the mine workers is damaged.
The common mine self-rescuer generally comprises three belt groups: braces, neckbands and belts for workers to carry in coal mines, but have the following disadvantages: the process is complex, the assembly time is long, and workers need to spend long time in assembling the straps, the neck straps and the waistbands, so that the self-rescuer is very unfavorable for the workers to use quickly and effectively, and even the life of the workers is influenced because the assembly process takes long time; meanwhile, the straps of the existing self-rescuer have too many parts and high cost; moreover, the variety is too many, and the use difficulty is high;
the locking device, the seal strip and the locking device are arranged on each common self-rescuer used in a coal mine, in the using process, after the locking device is protected and opened, the locking device is opened again, and the outer tank of the self-rescuer can be opened only after the seal strip is snapped.

One end of the locking belt 3, which is not connected with the left locking buckle 22 or the right locking buckle 24, is connected with the self-rescuer in a spot welding mode, on one hand, the spot welding function ensures the connection of the locking belt 25 and the self-rescuer, on the other hand, under an emergency situation, the self-rescuer can break the connection of the locking belt 25 and the self-rescuer only by applying a slight force so as to open the self-rescuer.
The sealing strip-free locking device is simple and quick in use process and does not need excessive steps.
When the medicine is filled into the cleaning tank 8, in order to avoid the expiration pipe 7 in the cleaning tank 9, the medicine adding hole 6 at the bottom of the cleaning tank 8 is arranged at one side close to the oxygen tank 5, and in order to ensure the stability of the self-rescuer during placement, the medicine adding hole 6 is recessed into the cleaning tank 8, and the self-rescuer is also provided with a hole cover matched with the medicine adding hole 6.
Specifically, respiratory device includes the cleaning tank upper cover and installs gasbag 3 on the cleaning tank upper cover, the cleaning tank upper cover is established on cleaning tank 8, cleaning tank upper cover is equipped with exhaling pipe 7, exhaling pipe 7 is located cleaning tank 8, exhaling pipe 7 is linked together with gasbag 3, be equipped with the filter screen between cleaning tank upper cover and gasbag 3.
In order to prevent dust from entering the air bag, glass wool is arranged between the upper cover of the cleaning tank and the filter screen.
In the embodiment, the model of the mining self-rescuer is ZYX45, and for the model of the self-rescuer, the thickness of the glass floss is 0.19-0.21 mm; the density of the glass silk floss is 27.1-27.3 g/m2；
The following results can be obtained through experiments: if the filter screen is not provided with the glass silk floss, the expiration resistance of the self-rescuer is 912Pa, the inspiration resistance is-824 Pa, and the powder leakage amount is 3 g;
if glass silk floss is added: if the thickness of the glass floss is 0.19mm, the density is 27.1g/m2When the temperature of the water is higher than the set temperature,the exhalation resistance of the self-rescuer is 366Pa, the inhalation resistance is-244 Pa, and the powder leakage amount is 8 mg; if the thickness of the glass floss is 0.2mm, the density is 27.2g/m2When the powder leakage amount is 8mg, the exhalation resistance of the self-rescuer is 307Pa, the inhalation resistance is-207 Pa; if the thickness of the glass floss is 0.21mm, the density is 27.3g/m2When in use, the exhalation resistance of the self-rescuer is 373Pa, the inhalation resistance is-240 Pa, and the powder leakage amount is 8 mg;
