Abstract
The utility model discloses a kind of cooling structure of smoke exhaust fan, it is characterized in that including inner cylinder and motor, discharge pipe is connected with the back cover of inner cylinder, blast pipe is connected with the front shroud of inner cylinder, the discharge pipe and blast pipe all extend to the outside of fan casing, in addition to inner coil pipe and cooling water tank, the inner coil pipe is in inner cylinder, it fits with the inwall of inner cylinder, and the water inlet pipe and outlet pipe of the coil pipe all extend to the outside of fan casing, and are connected to cooling water tank；By blast pipe and discharge pipe, the air flow in inner cylinder can be made, the heat that motor is produced, and the partial heat of inner cylinder are taken away；On the other hand cooling water is passed through in inner coil pipe, because inner coil pipe is fitted with the inwall of inner cylinder, so that cooling water is contacted with the inwall of inner cylinder, realize heat exchange between the two, and then take away the heat of inner cylinder, worked so as to ensure that motor can be under normal temperature for a long time, it is ensured that the normal operation of motor, and stability during operation.
Description
Technical field
The utility model is related to a kind of blower fan, and in particular it is related to a kind of cooling structure of smoke exhaust fan.
Background technology
According to the development trend of current domestic various ventilating engineerings, the underground system engineering of each big and medium-sized cities is more and more.
Smoke exhaust fan is the important component of underground system engineering fire-fighting system, is indispensable ventilating product；Simultaneously as ground
Lower systems engineering has the features such as space is small, air-conditioning requirement is high, and smoke exhaust fan will usually also serve as the work of daily ventilation toward contact
With.Higher requirement is thus proposed to smoke exhaust fan, smoke exhaust fan should be met under fire fighting state（280 DEG C of normal works
0.5 hour）Normal operation, the normal operation of mean time ventilation is met again.At present, general smoke exhaust fan disappears in order to meet
Under anti-state（280 DEG C of normal works 0.5 hour）Normal operation, set and be separated by with air flow channel inside axial flow fan shell
From inner cylinder, motor is placed in inside inner cylinder.Such structure can make blower fan avoid high-temperature flue gas in a short time to electricity
The infringement of motivation, but if longtime running, the heat that motor is produced in itself can not be distributed in time, influence blower fan is transported for a long time
Capable stability.On the other hand, because the outer wall of inner cylinder is directly contacted with high-temperature flue gas, so the temperature of inner cylinder in itself can be short
Rise in time, so as to further have impact on the normal operation of motor.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of cooling structure of smoke exhaust fan so that motor
It is prolonged under high-temperature flue gas to carry out steady operation.
To achieve the above object, the utility model provides following technical scheme：
Discharge pipe, inner cylinder are connected with a kind of cooling structure of smoke exhaust fan, including inner cylinder and motor, the back cover of inner cylinder
Front shroud on be connected with blast pipe, the discharge pipe and blast pipe all extend to the outside of fan casing, in addition to inner coil pipe and
Cooling water tank, the inner coil pipe is in inner cylinder, and it fits with the inwall of inner cylinder, and the water inlet pipe and outlet pipe of the inner coil pipe are equal
The outside of fan casing is extended to, and is connected to cooling water tank；By blast pipe and discharge pipe, the air stream in inner cylinder can be made
Dynamic, the heat that motor is produced, and the partial heat of inner cylinder are taken away；On the other hand cooling water is passed through in inner coil pipe, by
Fitted in inner coil pipe with the inwall of inner cylinder so that cooling water is contacted with the inwall of inner cylinder, realize heat exchange between the two, and then
The heat of inner cylinder is taken away, worked so as to ensure that motor can be under normal temperature for a long time, it is ensured that the normal fortune of motor
OK, and operation when stability.
It is preferred that, the water inlet pipe of inner coil pipe is in blast pipe, and the outlet pipe of inner coil pipe is in discharge pipe；The setting is kept away
The contact of water inlet pipe, outlet pipe with high-temperature flue gas is exempted from, it is therefore prevented that the air conditioning quantity of cooling water directly consumes situation outer tube；
On the other hand, when cooling water passes through, the temperature in blast pipe and discharge pipe can also be reduced.
It is preferred that, it is equipped with switch valve on the water inlet pipe of the blast pipe and inner coil pipe；The setting can be to air-flow and current
Break-make effectively controlled.
Brief description of the drawings
Fig. 1 is the schematic diagram of the cooling structure of smoke exhaust fan.
Embodiment
The cooling structure of the utility model smoke exhaust fan is further described by Fig. 1.
A kind of cooling structure of smoke exhaust fan, including inner cylinder 1 and motor, motor is in inner cylinder 1, after inner cylinder 1
It is connected with cover on discharge pipe 3, the front shroud of inner cylinder 1 and is connected with blast pipe 5, the other end connecting fan of blast pipe 5, so as to realize
The flowing of air in inner cylinder 1, the heat in inner cylinder 1 is taken away, and the discharge pipe 3 and blast pipe 5 all extend to fan casing
It is outside.Also include inner coil pipe 2 and cooling water tank, the inner coil pipe 2 is in inner cylinder 1, i.e., the section of inner coil pipe 2 is semicircle,
It forms sealed tube between the inwall of inner cylinder 1, and the flowing of Cooling Water, the water inlet pipe 6 and outlet pipe 4 of the inner coil pipe 2 is equal
The outside of fan casing is extended to, and is connected to cooling water tank（Figure of description is not marked）, water tank is interior to be located at suction pump, will
Cooling water is pumped into inner coil pipe 2, realizes heat exchange.
Further, the water inlet pipe 6 of inner coil pipe 2 is in blast pipe 5, and the outlet pipe 4 of inner coil pipe 2 is in discharge pipe 3.
Further, switch valve, i.e. ball valve are equipped with the water inlet pipe 6 of the blast pipe 5 and inner coil pipe 2.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
