A safety cabinet comprising: an outer housing having a door at the front and comprising a plurality of outer walls; An inner housing having a plurality of inner walls forming an inner chamber for accommodating a hazardous material inside the outer housing; An air duct provided between an inner wall and a rear wall facing the inner housing and the outer housing; An outer air intake port provided at one side of the outer wall forming the air duct; And an inner air inlet formed at an inner wall of the air duct to be spaced apart from the air inlet by a predetermined distance.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety cabinet, and more particularly, to a safety cabinet capable of protecting a container for storing an acid base material, a flammable substance, and the like, which is internally stored from external heat.
A cabinet for storing a safety cabinet used in a laboratory or the like, in particular, an acid base material or a flammable material, has an exhaust structure for discharging a dangerous substance gas generated from the inside to the outside. This exhaust structure has a structure in which the gas inside is discharged to the outside and fresh air is introduced from the outside.
In accordance with international standards, these safety cabinets must maintain the internal temperature from external flames below the natural ignition point for a certain period of time. This is because the chemical contained in the cabinet ignites at approximately 180 degrees, so the natural ignition point applied to the cabinet is 180 degrees. Such a cabinet should be maintained at a temperature lower than the natural ignition temperature for at least a predetermined time when the cabinet is exposed to external heat generated by a fire or the like.
Such a safety cabinet has a structure in which external air can be introduced into the cabinet, as described above. When a fire occurs through such an air inflow path, external heat or flame can be directly introduced into the cabinet.
The present invention provides a safety cabinet in which external heat can effectively suppress the inflow of flames.
The present invention provides a safety cabinet capable of safely protecting the inside of the apparatus from external heat or flames, thereby safely protecting dangerous materials stored therein.
A safety cabinet according to the present invention comprises:
An outer housing having a front door and including a plurality of outer walls;
An inner housing having a plurality of inner walls forming an inner chamber for accommodating a hazardous material inside the outer housing;
An air duct provided between the inner wall and the outer wall facing the inner housing and the outer housing;
An outer air intake port provided at one side of the outer wall forming the air duct; And
And an inner air intake port provided at an inner wall forming the air duct and spaced apart from the air inlet by a predetermined distance.
According to an embodiment of the present invention, the outer suction port and the inner suction port may be formed in the rear wall of the outer housing and the inner housing.
According to another embodiment of the present invention, an exhaust port for exhausting air to the outside may be provided at an upper portion of the outer housing.
According to another embodiment of the present invention, a partition wall separating the duct from the first duct and the second duct is formed between the outer housing and the rear wall of the inner housing, and the first duct and the second duct The outer suction port and the inner suction port may be spaced apart from each other by a predetermined distance in the rear wall of the outer housing and the inner housing.
According to another embodiment of the present invention, the rear wall includes a plurality of plate members arranged in parallel to each other, and the partition wall partitioning the duct may be formed by a substantially L-shaped flange portion formed on the plate member .
According to another embodiment of the present invention, a door check is coupled to the door, and a door check protecting space in which the door check is received is provided on the upper portion of the housing.
According to the present invention, the outer air intake port and the inner air intake port are formed to be shifted from each other, and an air intake duct is provided therebetween, so that flames or heat from the outside of the cabinet do not directly flow into the chamber inside the housing, So that the internal housing can block or delay the direct inflow of flame or heat to protect the internal hazardous materials.

In the event of a fire, hot flame vapors tend to rise to the top. In this case, the intake vents located in the upper rear of the cabinet are more likely to be exposed to flame vapor, but flame vapors that pass through it must descend through the rear duct to enter the cabinet interior system. In this process, a resistance against the air flow is generated, and therefore, the effect of hindering the entry of the hot flame air into the inside is exhibited. Further, in the case of the air intake port located in the lower rear portion of the cabinet, the probability of exposure to the flame vapor is low. Unless the rear of the actual cabinet is entirely enclosed by the flame, there is less likelihood of entering the interior through the relatively lower intake port.
In such a structure, by dividing both air inlets, the expected heat transfer level can be lowered according to the fire situation when a fire occurs.
Such a structure of the present invention is advantageous in that no additional process is required because it can be constructed using a bent surface for assembling the cabinet outer wall body.
As in the conventional structure, a thermal expansion filter for closing the interior of the inside of the
When a fire occurs from the outside, for example, when the front door is open, the door check is melted by the heat, so that the front of the chamber is closed by the operation of the door check and the outside air inlet and the inside And is blocked by the thermal expansion filter of the intake port. In this process, before the thermal expansion filter sufficiently inflates, outdoor air or flame is prevented from being directly introduced into the inner chamber by the intake structure according to the feature of the present invention as described above.

Here, the outer air intake port and the inner air intake port may be one large through-hole or a collection of a plurality of small through-holes. Further, the intake port may be provided at one or a plurality of locations with respect to one duct.
The safety cabinet according to the present invention having the above structure can safely store various kinds of dangerous substances, for example, acid base materials or flammable materials.
The safety cabinet according to the present invention has been tested by Korea Institute of Construction & Living Environment Test. The data are as follows.
The test report number is CT15-038189, which was conducted on three flame resistant (safety) cabinets according to the present invention.
As a result, the following results were obtained.
※ At the request of the client, the test was finished 41 minutes and 10 seconds after the start of the test. The test result is the result of 41
※ Composition and Material of Test Specimen (Presented to the client):
The conditions of the fire test under the above test conditions are shown in the following table.
10 is a graph showing changes in the temperature of the test object in the furnace, and the table below shows changes in the furnace temperature (standard temperature and actual temperature) and the error thereof.
Table 4 below shows the temperature change of the internal thermocouple of the test body.
Tables 4 and 5 below show the temperature changes from channel 1 to channel 14 (CH1 to CH25) of the internal thermocouple of the test body. Here, CH1 to 14 represent the double-face cabinet, and CH15-27 represents the cabinet for the short-form.
Through the above tests, it was found that the safety cabinet according to the present invention can safely protect the internal hazardous materials from the flame for a certain period of time.
As described above, the present invention is not limited to the above-described embodiment, and it is needless to say that variations can be made by those skilled in the art without departing from the spirit of the present invention.
