Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection relations mentioned herein do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Referring to fig. 1, a fire extinguishing box includes a box body 100, a cavity is provided in the box body 100, a side wall of the box body 100 is provided with an air inlet 110 communicated with the cavity, another side wall of the box body 100 is provided with an air outlet 120 communicated with the cavity, a partition board 200 is provided in the cavity and divides the cavity into an upper cavity and a lower cavity, the partition board 200 is inclined downward from the air inlet 110 to the air outlet 120, the air inlet 110 is located below the partition board 200, the air outlet 120 is located above the partition board 200, a plurality of sawtooth sections sequentially connected from the air inlet 110 to the air outlet 120 are provided on the partition board 200, and vent holes are provided on the surface of the sawtooth sections.

As can be seen from the above, the partition plate 200 partitions the cavity in the box body 100 into an upper cavity and a lower cavity, the gas inlet 110 is located in the lower cavity, the waste gas is introduced into the cavity and then hits on the partition plate 200, the gas passes through the gas vent, while the large particulate matters are blocked by the partition plate 200 and fall to the bottom of the cavity, since the partition 200 has the sawtooth sections, so that the partition 200 forms a multiple-fold structure, the exhaust gas passes through the partition 200 from the inlet 110 to the outlet 120, and is blocked for a plurality of times, thereby improving the filtering efficiency of the large granular substances, if the large granular substances falling at the bottom of the cavity contain inflammable substances, the large granular substances can only be combusted in the lower cavity, the combustible can not enter into the upper cavity, and the fire can extinguish after the combustible is burnt, so that the fire source can be blocked ingeniously, and due to the multiple blocking, the blocking effect is good, the overall structure is simple, and the practicability is high.

The shape of the sawtooth section on the partition board 200 is zigzag, that is, the sawtooth section has a structure of up-down reciprocating wave folding, in this embodiment, the sawtooth section includes an inclined baffle 210 and a vertical baffle 220, the inclined baffle 210 and the vertical baffle 220 are both provided with the vent hole, the inclined baffle 210 inclines downwards from the air inlet 110 to the air outlet 120, the vertical baffle 220 is arranged along the vertical direction, in one sawtooth section, the bottom edge of the inclined baffle 210 is connected to the bottom edge of the vertical baffle 220, and in any two adjacent sawtooth sections, the top edge of the inclined baffle 210 in one sawtooth section is connected to the top edge of the vertical baffle 220 in the other sawtooth section. Oblique baffle 210 forms a ripple structure with perpendicular baffle 220, a plurality of sawtooth sections connect gradually, can form multiple ripple structure, when the air current is through oblique baffle 210, oblique baffle 210 can produce the decurrent direction of slope to the air current, make large particulate matter blow down by the guide, and gas can pass the air vent on the oblique baffle 210, the heavier gas that is located the below can pass perpendicular baffle 220 once more, the large particulate matter that mix with in this type of gas is more, and the gas that is more is located the top, can be directly from last cavity to gas outlet 120, so can filter waste gas ingeniously.

The inclined baffle 210 guides the airflow so that impurities are blown into the lower cavity, and in this embodiment, in one of the sawtooth sections, an included angle between the inclined baffle 210 and the vertical baffle 220 is 40 to 45 degrees. Controlling the angle of inclination of the inclined baffle 210 within this range reduces the effect on the flow rate of the gas flow.

In order to determine the structural shape of the sawtooth section, in the present embodiment, the ratio of the length of the slant gate 210 to the length of the vertical gate 220 is 1.5 to 2.5. When the air flow passes through the sawtooth section, a better blocking effect can be kept, and the influence on the flow speed of the air flow is reduced.

As shown in fig. 2, in order to facilitate cleaning and replacing the partition board 200 or cleaning the lower cavity, in this embodiment, a first bearing strip 310 is disposed on an inner side wall of the box 100 where the air inlet 110 is disposed, the first bearing strip 310 is located above the air inlet 110, a second bearing strip 320 is disposed on an inner side wall of the box 100 where the air outlet 120 is disposed, the second bearing strip 320 is located below the air outlet 120, one side of the partition board 200 is fixed on the first bearing strip 310, and the other side of the partition board 200 is fixed on the second bearing strip 320. The two sides of the partition board 200 are respectively fixed on the first supporting strip 310 and the second supporting strip 320, thereby completing the fixing of the partition board 200 in the box body 100.

When the partition board 200 is blown by a large airflow, in order to ensure the structural stability of the partition board, in this embodiment, one end of the first supporting strip 310 and one end of the second supporting strip 320 are connected with a third supporting strip 330, the other end of the first supporting strip 310 and the other end of the second supporting strip 320 are connected with a fourth supporting strip 340, the third supporting strip 330, the fourth supporting strip 340 and the partition board 200 are adapted to each other in shape, and the third supporting strip 330 and the fourth supporting strip are tightly attached to the bottom surface of the partition board 200. Third bearing strip 330 hugs closely in the bottom surface of baffle 200 with fourth bearing strip 340, carries the bearing to baffle 200, because its shape mutual adaptation for third bearing strip 330 is inseparabler with fourth bearing strip 340 and baffle 200's combination, and baffle 200 anti-wind pressure ability is stronger.
