Description
本发明涉及一种转子式选粉机，尤其涉及一种转子式选粉机导风器结构。The invention relates to a rotor-type powder separator, in particular to a rotor-type powder separator wind guide structure.
转子式选粉机配风机的风经切线方向进入选粉机时，经过以前的V型导风器整形，旋转上扬带起粉料进入选粉区参加转笼的选粉，由于老式的V导风器的为有缝结构等原因，会有一部份风从中间的空隙处吹进粗粉通道，造成瞬时风压和风量的变化，由于风压和风量的急剧变化，会使部份物料不能及时上扬参加转笼的选粉，故造成转子式选粉机的选粉效率偏低。When the wind of the rotor type powder separator and the fan enters the powder separator through the tangential direction, it is shaped by the previous V-type air deflector, and is rotated and lifted to bring the powder into the powder selection area to participate in the powder selection of the rotating cage. Due to the seam structure of the wind device, etc., a part of the wind will blow into the coarse powder channel from the gap in the middle, which will cause the instantaneous wind pressure and air volume to change. The powder selection in the rotating basket was raised in time, which caused the powder selection efficiency of the rotor type powder separator to be low.
发明内容Summary of the invention
本发明所要解决的技术问题是：提供一种选粉效率高的转子式选粉机导风器结构。The technical problem to be solved by the present invention is to provide a rotor type powder separator air guide structure with high powder selection efficiency.
为了解决上述技术问题，本发明采用的技术方案是：转子式选粉机导风器结构，包括：上锥部、中锥部、下锥部和设置在上锥部上的盖板。本发明的优点是：上述转子式选粉机导风器结构，为S型无间隙结构，并在最上采用盖板密封，减少了漏风率，最大程度上利用了旋转风，提高了转子选粉机的选粉效率。In order to solve the above technical problems, the technical solution adopted by the present invention is: a rotor-type powder separator wind deflector structure, comprising: an upper cone portion, a middle cone portion, a lower cone portion, and a cover plate disposed on the upper cone portion. The invention has the advantages that the above-mentioned rotor-type powder separator air guide structure is an S-type non-gap structure, and is sealed by a cover plate at the top, which reduces the air leakage rate, maximizes the use of rotating wind, and improves the powder selection of the rotor. Machine's powder selection efficiency.

In use, the lower cone 3 of the above-mentioned rotor-type powder separator air guide structure is fixed inside the air inlet cylinder of the powder separator, and the overall structure is S-shaped. The wind of the powder separator and the fan enters the powder separator through the tangential direction. At this time, after the S-shaped air deflector is shaped, it is rotated and lifted up to bring the powder into the powder selection area to participate in the powder selection of the cage. Due to the low leakage rate of the device, the air volume shaping effect is good, which greatly improves the utilization efficiency of the rotating wind. Increased the opportunity for powder to participate in powder selection, and the powder selection efficiency of the rotor type powder separator has been further improved.
