Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoke exhaust fans, in particular to a high-heat-resistant and high-stability fire-fighting smoke exhaust fan. Background Art
[0002] Fire smoke exhaust fan refers to an industrial fan that can run continuously for more than 60 minutes at a high temperature of 300°C and for 20 hours / time at a temperature of 100°C without damage. The types of fans include axial flow fans, centrifugal fans, and axial flow fans. Choose a machine of appropriate size according to the size of the space and the layout of the smoke exhaust hood. Fire smoke exhaust fans are driven by motors, and motors will generate high temperatures when running. Especially in the event of a fire, the smoke generated by the motor will also increase. As the temperature of the motor continues to rise, the motor will be damaged, making the smoke exhaust fan unable to work. However, the existing fire smoke exhaust fans on the market do not have a special cooling function for the motor, which causes the heat dissipation effect of the motor to deteriorate, making the motor easily damaged at high temperatures. At the same time, the running time of the motor will be shortened, which will reduce the smoke exhaust effect. Utility Model Content

[0024] Preferably, the outer wall of the heat-conducting arc plate 19 contacts the outer wall of the motor 7, the water suction port of the pump 5 is connected to the interior of the cold water tank 3, the upper end of the water supply pipe 12 is connected to the interior of the cooling chamber 8, and the lower end of the water suction pipe 21 is connected to the interior of the cold water tank 3.
[0025] Preferably, a second spring 20 is installed inside the heat conduction chamber 10 , and an outer end of the second spring 20 is connected to the outer side of the conduction block 18 .
[0026] Preferably, two protection frames 11 are fixedly installed at the lower part of the cooling bin 8 , and the water delivery pipe 12 and the water extraction pipe 21 are respectively installed inside the protection frames 11 .
[0027] Working principle: When the motor 7 is running, a lot of heat will be generated. People can control the water pump and the semiconductor refrigerator 4 to cool the coolant in the cold water tank 3, and then the pump 5 sucks the coolant. The coolant enters the cooling chamber 8 through the water pipe 12, and a plurality of heat-conducting curved plates 19 are attached to the surface of the motor 7. The heat generated by the motor 7 is transferred to the heat-conducting plate 9 through the heat-conducting curved plate 19, the conduction block 18, and the heat-conducting chamber 10. The heat-conducting plate 9 is in contact with the coolant, and the coolant can take away a lot of heat. Then the coolant will re-enter the cold water tank 3 through the pumping pipe 21 and get the semi-cooled coolant again. The refrigeration of the conductor refrigerator 4 allows the coolant to be circulated and cooled, ensuring that the coolant can always maintain a low temperature, which can then have a good cooling effect on the motor 7, allowing the motor 7 to operate stably for a longer time, and at the same time, the heat dissipation fins 22 on the outside of the fan barrel 2 can further improve the heat dissipation effect of the smoke exhaust fan and increase the service life of the smoke exhaust fan. The motor 7 will vibrate when working, and the conduction block 18 is slidably installed in the heat conduction bin 10. Through the setting of the second spring 20, the arc-shaped heat conduction plate 9 can always stick to the surface of the motor 7, and the protective frame 11 can protect the water supply pipe 12 and the water extraction pipe 21.
[0028] Embodiment 2:
[0029] See also Figure 1-4 A fixing frame 15 is fixedly installed on both sides of the front of the fan cylinder 2, and a limiting rod 16 is slidably installed inside the fixing frame 15. A first spring 17 is wound around the outer side of the limiting rod 16.

[0031] Working principle: Pull the limit rod 16, the limit rod 16 will move with the pressure plate, and the pressure plate will squeeze the first spring 17. After pulling the limit rod 16, the limit rod 16 will leave the limit hole on the side plate 14, so that the filter plate 13 loses the restriction, and then the filter plate 13 can be removed. During installation, the filter plate 13 is installed on the front side of the fan cylinder 2, and then the limit rod 16 is inserted into the limit hole under the pressure of the first spring 17, thereby restricting the installation of the filter plate 13, so that the filter plate 13 is easy to install and disassemble, and it is convenient to clean the filter plate 13.
