Description
Technical Field
The utility model relates to the technical field of fire-fighting smoke exhaust fans, in particular to a heat dissipation type fire-fighting smoke exhaust fan.
Background
After the fire-fighting smoke extractor is started to be used, the air extractor can heat and raise temperature, but because no air flow outside the casing flows rapidly, heat cannot be taken away rapidly, and long-time high-temperature heating can possibly cause damage to the air extractor.
Disclosure of utility model
The utility model aims to provide a heat dissipation type fire-fighting smoke exhaust fan, which aims to solve the problems that in the background technology, an air exhaust device generates heat and heats up, but the outside of a shell of the air exhaust device does not flow fast and cannot take away heat fast.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
The utility model provides a heat dissipation formula fire control smoke exhaust fan, includes the outlet duct, the integrative intake pipe that is equipped with in the outside of outlet duct, the junction of outlet duct and intake pipe forms the intermediate layer, the inner fixed mounting air exhauster of outlet duct, the outlet duct is located the position of air exhauster and outlet duct, intake pipe junction and offers the through-hole around the axis, the outer fixed mounting filter screen of intake pipe.
As a further description of the above technical solution:
the part of the air inlet pipe connected with the air outlet pipe is of an oblique shrinkage structure.
As a further description of the above technical solution:
the air inlet pipe and the filter screen are of buckle fixing structures.
As a further description of the above technical solution:
The through opening is communicated with the interlayer.
Compared with the prior art, the utility model provides the heat dissipation type fire-fighting smoke exhaust fan, which has the following beneficial effects:
1. According to the utility model, the shell structure of the smoke-eliminating and smoke-exhausting fan is improved, so that air flow passes through the outer side of the exhaust fan, so that part of heat on the surface of the exhaust fan can be taken away, and the position temperature of the exhaust fan is prevented from being too high;
2. according to the utility model, the filter screen is arranged, so that sundries can be prevented from entering due to the large opening of the air inlet pipe, and the sundries can be prevented from entering the interlayer to block the through hole.

FIG. 1 is a schematic cross-sectional view of the present utility model;
fig. 2 is a schematic view of the external structure of the present utility model.
Legend description:
1. An air outlet pipe; 2. an air inlet pipe; 3. an interlayer; 4. an exhaust fan; 5. a through port; 6. and (5) a filter screen.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples:
referring to fig. 1-2, the utility model provides a heat dissipation type fire-fighting smoke exhaust fan, which comprises an air outlet pipe 1, wherein an air inlet pipe 2 is integrally arranged on the outer side of the air outlet pipe 1, an interlayer 3 is formed at the joint of the air outlet pipe 1 and the air inlet pipe 2, an exhaust fan 4 is fixedly arranged at the inner end of the air outlet pipe 1, a through hole 5 is formed at the joint of the air outlet pipe 1, the air outlet pipe 1 and the air inlet pipe 2 around an axis, and a filter screen 6 is fixedly arranged at the outer end of the air inlet pipe 2.
Specifically, as shown in fig. 1, the part of the air inlet pipe 2 connected with the air outlet pipe 1 is in an oblique shrinkage structure, so that the air flow inlet surface is enlarged, a part of air flow can enter the interlayer 3 conveniently, and the oblique shrinkage part has an air flow guiding function.
Specifically, intake pipe 2 and filter screen 6 are buckle fixed knot and construct, easily dismantle the clearance.
Specifically, as shown in fig. 1, the through hole 5 is communicated with the interlayer 3, so that air flow can enter the air outlet pipe 1 conveniently, and a complete air flow channel is formed.
Working principle:
When the flue gas is pumped, the exhaust fan 4 works, then gas enters the air inlet pipe 2 through the filter screen 6 and is discharged from the position of the air outlet pipe 1 through the exhaust fan 4, in the process, part of the gas entering the air inlet pipe 2 enters the interlayer 3, and enters the air outlet pipe 1 from the position of the through hole 5 due to flow inertia, so that the air flow passes through the position of the interlayer 3, part of heat of the exhaust fan 4 can be taken away, and the overhigh temperature of the exhaust fan 4 is avoided.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
