Description

Penetration device for explosion prevention of portable high pressure container

The present invention relates to a penetrating device for preventing explosion of a portable high pressure container for removing waste gas remaining in a storage container storing flammable gas, and in particular, continuously opens the outlet hole of the gas storage container with an extrusion pin of a simple configuration. The present invention relates to a penetrating device for explosion prevention of a portable high-pressure container to reliably remove residual gas in a container.

Generally, explosion or combustible gas is stored in a gas storage container which is selectively supplied with gas energy when necessary by being installed in a heating device such as a portable burner, or a spray container sprayed like an insecticide or a cosmetic product. Contains a high risk of liquefied gas.

Most of the gases contained in such storage containers have a property of exploding when a certain pressure or more and heat above a predetermined temperature are applied.

In addition, the above gas containers should be replaced by purchasing a new storage container when the service life of the gas containers has reached the end of their service life due to the passage of a certain use time.

Conventionally, most of the storage containers are manufactured to be relatively small and supplied to the consumer in order to facilitate their portability and transportation, and most of them are discarded after a single use.

As such, relatively small amounts of waste gas remain in storage containers discarded at the end of their service life.

Accordingly, when the gas storage containers are disposed of, waste gas remaining therein while being forcibly pressed by an artificial operation on the gas outlet pipe 21 installed at one end of the container cover 11 as shown in FIG. Is completely removed and discarded, or the gas remaining in the container is completely removed by discarding a hole using a nail or the like at the lower end of the container.

However, the general consumer is discarding the gas remaining in the container as it is quite cumbersome to remove the residual gas as described above, and also pays great attention to separate and dispose of these discarded gas storage containers so as not to mix with the general waste. In spite of the need, the work is cumbersome and users are avoiding it, and most of it is thrown away with the general garbage.

Gas storage containers that are discarded as described above are often exploded by waste gas remaining in the process of being incinerated with general wastes, resulting in injuries of workers and specialist workers who perform incineration. Dangerous accidents were often caused.

In addition, there is a problem that acts as a cause of serious human accidents and property damage while the fire (fire) occurs at the same time during the explosion.

Accordingly, the present invention has been made to solve the above problems, the portable high pressure vessel of the present invention can easily remove the waste gas remaining in the storage container for spraying gas storage container or insecticide used for one-time use The purpose is to provide a penetration device for explosion protection.

In addition, the present invention provides a penetrating device for preventing explosion of a portable high-pressure container to prevent injury and property damage by exploding waste gas remaining therein during the disposal of an abandoned gas storage container. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIG. 2.

The through device for preventing explosion of the portable high pressure container according to the present invention is largely composed of a storage unit 100, a gas supply unit 200, and a gas removal unit 300.

The storage unit 100 is capable of erasing pests such as flammable gas (GAS) and flies, mosquitoes, etc. to heat the food by supplying gas energy to a heating device such as a portable burner therein. A pesticide and the like is a container body to be mixed and stored with the gas, the container body 10 and the cover to cover the container body and consists of a main body cover 11 formed with a through-hole 12, mainly It is supplied to a consumer as a container body made to form a cylindrical shape. A support plate 23 having a through hole 23a formed therein is connected to a lower portion of the main body cover 11, and a fixing protrusion protruding upward from the inner periphery of the through hole 23a. 23b is integrally formed.

The gas supply unit 200 is a structure that allows the appropriate amount of the pesticide or mixed with the gas and gas contained in the container body 10 to be selectively discharged or sprayed when necessary.

As shown in FIGS. 2 to 4, the gas supply unit 200 is equipped with a gas nozzle 21 fitted into the through hole 12 of the main body cover 11. The gas nozzle 21 moves straight from the through hole 12 by an external force.

The gas nozzle 21 has a groove portion 21c formed to fit the inner circumferential surface of the rubber packing 24 to be described later on an outer circumferential surface of the middle portion thereof, and a gas outlet passage 21a penetrated in the longitudinal direction and the groove portion ( Outflow hole 21b communicating with the gas outlet passage 21a side is formed in 21c.

In addition, first and second protrusions 31a and 31b are formed at both centers at the inlet of the gas outlet passage 21a of the gas nozzle 21, and the first protrusions 31a of the both protrusions are inserted and sealed. The disk-shaped sealing plate 31 is mounted. The gas nozzle 21 in the present embodiment is made of an engineering plastic or a curable synthetic resin material, and the sealing plate 31 is made of a soft synthetic resin material.

In addition, one side is fixed to the second projection (31b) of the sealing plate 31, the other side is fixed to the fixing projection (23b) formed in the periphery of the through hole (23a) of the support plate 23 to move the gas nozzle 21 The spring 22 is provided to provide a restoring force according to the present invention.

Meanwhile, an inner circumferential surface is inserted into the recess 21c of the gas nozzle 21, and an outer circumferential surface is mounted with a rubber packing 24 mounted and supported by a locking groove 11a formed on the inner wall of the main body cover 11. The gap between the through hole 12 of the cover 11 and the gas nozzle 21 and the outlet hole 21b are sealed.

In the gas supply unit 200 configured as described above, the gas nozzle 21 is normally sealed by the rubber packing 24, and when the gas nozzle 21 is pressed by an external force, the groove is formed by the linear movement thereof. The rubber packing 24 inserted into 21c is pushed out to open the outlet hole 21b, and accordingly gas in the container body 10 is discharged to the gas outlet passage 21a through the outlet hole 21b. will be. In addition, when the external force that pressed the gas nozzle 21 is removed, the gas nozzle 21 is returned to its original position by the original position restoring force of the spring 22, and the rubber packing 24 is also restored to its original state to block the outflow of gas. It is done.

Waste residual gas removal unit 300 for removing residual gas in the container body 10 is a gas withdrawal passage 301a formed to be hollow in the longitudinal direction as a waste residual gas outflow passage as shown in FIGS. 6A and 6B. And an extrusion pin 301 having a drawing hole 301b penetrating toward the gas drawing passage 301a from the outer peripheral surface of the lower end portion thereof. Therefore, when the extruded pin 301 is inserted into the gas outlet passage 21a of the gas nozzle 21 by a punching means such as a hammer, the lower end of the gas outlet passage 301a of the extruded pin 120 is inserted. The first protrusion 31a of the sealing plate 31 is blown away in a shielded state, and accordingly, residual gas is discharged into the gas outlet passage 301a through the outlet hole 301b of the extrusion pin 301. will be.

The extrusion pin 301 in the present embodiment has an inclined guide surface 302 inclined downward by a predetermined section at its upper end, the teeth 303 is formed in multiple stages at the end of the inclined guide surface 302 Since the diameters of the inclined guide surface 302 and the teeth 303 are formed to be larger than the gas outlet passage 21a of the gas nozzle 21, the extrusion pin 301 is pushed into the gas outlet passage 21a when being beaten. It can be firmly inserted and fixed. Accordingly, the waste residual gas in the container body 10 may be continuously discharged through the withdrawal hole 301b of the extrusion pin.

In addition, as shown in Fig. 7a as another form of the extrusion pin 301 having the configuration as described above, the shape of the chamfering (chamfered portion "C" in the figure) at one side of the lower end at a predetermined inclination angle And a gas outlet hole 301a penetrates in the longitudinal direction as a waste residual gas outflow passage. At this time, the extruded pin 301 by hitting the sealing plate 31 to the unchamfered portion is separated, and accordingly to the residual gas is discharged through the gas withdrawal hole (301a).

In addition, as shown in FIG. 7B, the lower end portion of the extrusion pin 301 may be processed in a shape of a bending 301c facing upward. At this time, the thickness of the lower circumference of the lower end portion 301c from which the bent portion 301c is removed is hit by the sealing plate 31 so that the residual gas is discharged through the gas outlet hole 301a.

As shown in FIG. 7A and FIG. 7B, the process of reducing the process of processing the outlet hole 301b in the above-described embodiment can be reduced by allowing the gas to be directly communicated with the gas outlet hole.

Extrusion pin 301 as described above is made of engineering plastics to have durability even when applied to an external force, the extrusion pin can be mass-produced because the injection molding is possible.

In addition, as shown in Figure 8 as another embodiment of the extrusion pin, an example of forming the extrusion pin 401 using a leaf spring is shown. It is formed by rolling the leaf spring in a circular shape, with a portion having an open portion 401a cut in the longitudinal direction, and having a tapered shape at a predetermined angle θ. Therefore, there is no need for a separate mold for fabricating and producing an extrusion pin, thereby reducing manufacturing costs and simplifying a processing process, thereby allowing mass production.

The overall operation of the present invention configured as described above will be described in detail.

First, the gas nozzle 21 of the gas supply unit 200 is coupled to the through hole 12 formed at the upper end (as seen in the drawing) of the body cover 11. In this state, when the gas nozzle 21, which is partially exposed to the outside of the main body cover 11, is pushed into the container body 10 by forcibly pressing, the passage 21a together with the gas nozzle 21 ), The sealing plate 31 which has shielded) moves to compress the spring 24. Then, the rubber packing 24 coupled to the recess 21c of the gas nozzle 21 is pushed to open the outlet hole 21b formed in the recess 21c.

That is, when the gas nozzle 21 is forcibly retracted, the outer peripheral surface of the rubber packing 24 is caught in the locking groove 12a, so that the inner peripheral surface opens the sealing portion with the recess 21c. The outflow hole 21b is opened so that the gas in the container body 11 flows out through the gas outlet passage 21a. At this time, the gas nozzle 21 compresses the spring 22 elastically installed on the support plate 23. This state is shown in Figures 3 and 4 of the accompanying drawings.

By operating as described above to supply an appropriate amount of the flammable gas contained in the container body 11, or if a pesticide, such as flies, mosquitoes, etc. is required to be injected with the appropriate amount.

When the supply of the pesticide in the state mixed with the gas or the gas in the container 11 is to be stopped, the gas nozzle 21 causes the spring to be removed by removing the external force that presses the gas nozzle 21. By the free restoring force of 22), the rubber packing 24 is also restored so that the outflow of gas is stopped by the inner circumferential surface thereof shielding the outlet hole 21b.

When various combustible gases in the container body 10 are exhausted to reach a level at which normal use is impossible, only the amount of fine gas remains and the waste gas remaining in the container body 10 through the gas removing unit 300 is removed. Simply remove it to prevent explosion accidents.

That is, as shown in FIG. 9, when the extrusion pin 301 is inserted into the gas outlet passage 21a (upper view thereof) penetrated in the gas nozzle 21, the extrusion pin 301 The gas outlet passage 301a of the lower end side of 301 hits and escapes while shielding the first protrusion 31a of the sealing plate 31 to open the gas outlet passage 21a.

At this time, the upper portion of the extrusion pin 301 is formed with an inclined guide surface 302 is forcibly fitted to the inner peripheral surface of the tip side of the gas outlet passage (21a) is coupled. Therefore, the extrusion pin 301 does not come out even when the force pinch force is removed from the extrusion pin 301, so that the residual gas in the container body 10 is continuously discharged to the outside through the drawing hole 301b. will be.

This allows the operator to easily discharge the waste gas by a short time operation, so that anyone can conveniently perform this discharge operation for safety.

The extruded pins 301 are distributed in a state in which each of the extruded pins is attached to one side of the container body 10 by a detachable tape or the like, but the structure is simple and the volume is very small so that the cost is hardly affected. Is to be used for safety.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As described above, according to the present invention, by removing the waste gas remaining in the container body simply and reliably by squeezing the extrusion pin into the gas outlet passage which is perforated through the gas nozzle, the residual gas removal operation is simplified. Anyone can handle it, and accordingly safe incineration can be made, and it is useful to have the advantage of preventing accidents and casualties and property damage caused by not removing the waste gas remaining in the container body.
