[0003]
Centrifugal fans are often used for ventilation and air induction at the air duct of the kiln. The centrifugal fan is used to push the air in the air duct. When in use, due to the high temperature generated by the kiln, when the conventional centrifugal fan is used, Closer to the air duct, the heat generated will heat up the inside of the centrifugal fan, resulting in thermal lockup of the centrifugal fan, which will affect the use of the centrifugal fan, and the maintenance will consume a lot of time and energy for workers

The invention discloses an efficient kiln centrifugal fan with a high-temperature protection washing air duct. The efficient kiln centrifugal fan comprises a box and a frame, wherein a motor is fixedly installed at the top of the box, a bellows is fixedly connected to one side of the box, a heat dissipation pipe is movably installed at the top of the frame, the two ends of the heat dissipation pipe are communicated with a water inlet pipe and a water outlet pipe respectively, threaded rings are fixedly installed at the end, away from the heat dissipation pipe, of the water inlet pipe, the surfaces of the threaded rings are in threaded connection with a shielding cover, and a blocking ball is rotatably installed in the water inlet pipe. Water flow is injected from one end of the water inlet pipe, the water flow cools the motor when passing through the heat dissipation pipe, and the water flow is discharged from the water outlet pipe after absorbing heat, so that the influence of the heat of a kiln on the motor is reduced. The heat generated by the kiln can be absorbed by using the device, and the situation that the centrifugal fan is close to the air duct during use, the heat generated by the kiln can heat the interior of the centrifugal fan, and then the centrifugal fan is locked due to heating is avoided.
Description
technical field [0001] The invention belongs to the technical field of centrifugal fans, and in particular relates to a high-efficiency kiln centrifugal fan with a high-temperature protective washing air duct. Background technique [0002] Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Ventilation, Dust extraction and cooling, ventilation and drafting of boilers and industrial kilns, cooling and ventilation in air-conditioning equipment and household appliances, drying and selection of grains, and inflation and propulsion of wind tunnel sources and hovercraft, etc. [0003] Centrifugal fans are often used for ventilation and air induction at the kiln air duct. The centrifugal fan is used to push the air in the air duct. During use, due to the high temperature generated by t...
