Tornado vacuum hood

The effectiveness of electric furnace flue gas capture depends to some extent on the structural form of the hood. If the design of the vacuum hood is reasonable, using a smaller exhaust volume can effectively control the dispersion of dust. Conversely, using a larger exhaust volume may not necessarily achieve the expected effect. Our company's technical personnel are setting upTornado vacuum hoodThe following principles should be followed: (1) The setting of the vacuum hood should be determined according to the principle of preventing dust from escaping into the surrounding environment space, and the suction of the vacuum hood should make use of the movement effect of the polluted airflow as much as possible. （2） Vacuum hoods should not be placed in areas with high dust content in the airflow to avoid inhaling large amounts of powder. （3） The vacuum hood needs to have a certain amount of space to buffer the airflow and reduce positive pressure. When connected to the nozzle, the contraction angle should not exceed 60 °. （4） The vacuum hood should surround the dust source as much as possible to minimize the spread of dust and facilitate dust collection, thereby reducing the exhaust volume to a certain extent. （5） Vacuum hoods should strive for a simple structure, easy installation, and not affect process operation and maintenance management. 1. Choose based on the form of smelting and feeding without affecting the operation. 2. Design according to the size and inclination of the furnace mouth to achieve efficient capture to a large extent. 3. There are two types available for customers to choose from: manual and electric.

4Tornado vacuum hoodCompared with traditional hydraulic tilting vacuum cleaners, its advantage is that it can not only tilt back and forth, but also stay in any position. Traditional vacuum cleaners can only stay at the front and rear workstations. During the operation of the furnace floor workers, the cyclone style vacuum hood avoids the baking of the operator by the forward flipping furnace cover, reducing the workload of the operator.

5. A vacuum hood with a furnace cover, a sturdy steel structure design, and a refractory furnace cover fixed in the middle of the vacuum hood. The entire vacuum hood can be stopped at any position through a hydraulic cylinder. 6. During the electric furnace melting process, the entire vacuum hood is in a closed position, with the furnace cover covering the crucible of the melting pool to reduce heat loss during feeding, melting, and burning. At the same time, the vacuum hood uses a certain amount of suction air to remove dust and exhaust gas, achieving the effect of reducing exhaust gas emissions. 7. The steel vacuum hood shell can be opened forward and backward by a hydraulic cylinder, and is connected to the exhaust gas discharge pipeline system through a flange located on the rotating shaft of the furnace body. 8. When the entire vacuum hood is opened in the forward direction, perform the feeding operation. 9. The entire vacuum hood can be opened in reverse, which is beneficial for repairing the induction coil without disassembling the vacuum hood; It is also convenient for repairing the pouring port of the induction furnace. 10. The vacuum hood with furnace cover should operate under the condition of meeting the following suction air volume (for a single furnace body). Attention: Long term operation of the vacuum hood in a state of no wind or insufficient air volume may cause equipment damage.
