Rotary hood of aluminum electrolytic induction melting furnace for collecting flue gas of induction melting furnace in anode production workshop of electrolytic production .

  Electrolytic induction melting furnace rotary anode assembly cover is aluminum electrolysis plant induction melting furnace collection means flue gas, the anode assembly is directly related to plant induction melting furnace successful or not flue gas treatment. Its role is to make the induction melting furnace flue gas in the anode assembly workshop not diffuse inside the workshop, collected by the device, and then discharged to the outside through the system. The traditional induction melting furnace flue gas of the anode assembly workshop adopts the natural exhaust type of the sunroof and the mechanical exhaust type of the axial fan installed on the side wall. These two types of exhaust effect are not good.

The purpose of the aluminum electrolytic induction melting furnace hood is to prevent the induction melting furnace flue gas from diffusing in the anode assembly workshop .

Reconstructed structure: an exhaust hood is provided at the end of the exhaust pipe, and a gyrator is provided at the other end of the exhaust pipe. The exhaust pipe is fixed on the support through an air pipe support. The bracket is a right-angled triangle bracket, and the short right-angled side of the right-angled triangle is a shaft. Both ends of the shaft are provided with an upper bearing and a lower bearing. The upper bearing and the lower bearing are fixedly connected to the steel column through the upper bearing and the lower bearing. An end of the exhaust pipe provided with a gyrator is fixed on a steel column through an air pipe bracket. The exhaust hood is a circular umbrella-shaped exhaust hood, and the opening of the circular umbrella-shaped exhaust hood faces downward. The diameter of the circular umbrella exhaust hood is 1000mm ～ 1600mm. The height of the circular umbrella exhaust hood is 800-1500mm from the operating surface. The height of the steel column is 4000 ～ 5000mm. The height of the exhaust pipe from the operating surface is 2000 ~ 3000mm. The diameter of the exhaust pipe is 400 ~ 600mm. The exhaust pipe rotates at 50 degrees. ~ 80. The induction melting furnace flue gas is collected and discharged from the anode assembly workshop. Since the exhaust hood in the device can be rotated and an exhaust hood is set near the induction melting furnace , the exhaust effect is very obvious, and it does not affect the requirements of process production.
