The design of X700 eddy type powder selecting machine (the design of rotor parts)
Abstract : In order to satisfy requirements of modern cement enterprise more and more high production, this topic designs and improves X700 eddy type powder selecting machine. This design adopts the method which combine theories design with experience design. First, at the base of analyze advantages and disadvantages of the former rotor type of machine, the cage rotor which can enhance the graduation field of force is designed by analogy method. Refering advantages of o-sepa powder selecting machine air ducting is used to enhance the eddy effect. The combination of cage rotor with air ducting cause the material evenly to absorb the graduation force so that the powder efficiency has been improved. Its transmission system adopts belt pulley transmission, because leather belt transmission is low in failure transmission, convenient in service and adjustment. The rotor is consisted of wear-resisting steel piece and lap, around the middle of the lap has seventy holes. The steel piece goes through the lap and welding with the lap, to guarantee its stability. The board under the rotor install conical body gets up reinforces the rotor to strengthen the ascendant current. The material scatters installment made of the wear-resisting casting volume production put it on top of the rotor, saves the cost, uses the bold fastening, convenient in service. Use the wear-resisting ceramic tile instead of the formerly board wear-resisting way. The wear-resisting has good effect、lower in cost. Between the axis and the axle sleeve seals uses the bath lubrication, enhances the lubrication effect. After the process transformation make the machine reduce the movement cost greatly ,enhanced the production efficiency, achieved high efficiency in choosing the powder, low in energy consumption, convenient in service.
