Angle regulating device of steam powder machine feed nozzle

Abstract

The invention provides an angle regulating device of a steam powder machine feed nozzle. A feed nozzle is supported on an end cover of a feed inclined pipe in a movable mode. The angle regulating device comprises a regulating plate and four regulating screws. The regulating plate is fixed on the feed nozzle outside of the feed inclined pipe vertically. Directions of the four regulating screws are in accordance with an extension direction of the feed nozzle, and the four regulating screws are distributed in an upper portion, a lower portion, a left portion and a right portion of the feed nozzle. Pole parts of the four regulating screws are in threaded connection with the regulating plate and penetrate through the regulating plate. Tail parts of the four regulating screws are topped on the end cover of the feed inclined pipe. An interval is arranged between the regulating plate and the end cover of the feed inclined pipe. When the feed nozzle deflects, the regulating screws are rotated correspondingly so as to achieve regulating the angle of the feed nozzle. The four regulating screws are distributed in an upper portion, a lower portion, a left portion and a right portion of the feed nozzle. The four regulating screws are distributed in the upper portion, the lower portion, the left portion and the right portion of the feed nozzle so as to achieve poly-directional regulations of the feed nozzle. An outlet end of the steam powder machine feed nozzle locating in the center of the steam powder machine feed inclined pipe all the time is ensured. The quality and the yield of steam powders are improved.

Description

technical field [0001] The invention relates to a steam powder machine, in particular to a device for adjusting the angle of a feeding nozzle of a steam powder machine. Background technique [0002] The steam powder machine is a device that uses the energy of high-speed superheated steam to make particles impact, collide, and rub against each other to achieve ultra-fine crushing or depolymerization. In the production of titanium dioxide, the steam powder machine is used as the final crushing equipment for finished products. The equipment has multiple abrasive nozzles, which are used to form an air ring to increase the contact probability of materials and improve the crushing effect. It also has a feeding nozzle, which uses the negative pressure formed near the high-speed steam flow to drive the materials into the steam powder machine, and sends the materials into the steam powder machine. The material crushing area inside the steam powder machine. The feeding nozzle is a...

AI Technical Summary

Problems solved by technology

The feeding nozzle is affected by the high temperature environment, and the phenomenon of thermal expansion and contraction is obvious. Uneven heating can easily cause the angle of the nozzle to shift, and the spraying distance will be enlarged, which mainly affects the following two aspects: (1) The high-speed air flow at the outlet of the feeding nozzle is caused by If the direction is not correct, it will corrode the feeding inclined tube of the upper cover of the steam powder machine, causing damage to the upper cover and scrapping the whole machine; (2) The steam flow from the outlet of the feeding nozzle hits the wall of the feeding inclined tube, causing the material to be unable to be effectively fed into the steam powder machine In the crushing area, spraying material is formed, which not only affects the environment of steam powder, but also seriously affects the quality and output of steam powder
