Embodiment 1

[0012] When the spray gun is working, the stainless steel spray gun outer tube 1 wraps the stainless steel spray gun inner tube 2, and the two are hollow structural design to prevent the temperature of the spray gun from rising too high. The high-temperature material first comes into contact with the ceramic protective layer 3 of the spray gun. The high temperature resistance and wear resistance of the ceramic protective layer are higher than those of the heat-resistant stainless steel tube, which prolongs the service time of the Maerz kiln spray gun, reduces damage, saves equipment costs, and increases efficiency.

Embodiment 2

[0014] When the spray gun is working, the stainless steel spray gun outer tube 1 wraps the stainless steel spray gun inner tube 2, and both are hollow structural design to prevent the temperature of the spray gun from rising too high. The front end of the protective cover is provided with a backstop part 4 that prevents the ceramic protective cover from falling off, to prevent the ceramic protective cover of the spray gun from contacting and rubbing against the high-temperature material and falling off. The backstop part 4 is a backstop ring or a backstop snap ring. The ceramic protective cover that comes into contact with the spray gun, the high temperature resistance and wear resistance of the ceramic protective cover are higher than those of the heat-resistant stainless steel tube, which prolongs the service time of the spray gun in Maerz kiln, reduces damage, saves equipment costs and increases benefits.

Abstract

The invention discloses a double-protection spray gun for a Maerz kiln. The double-protection spray gun comprises a stainless steel spray gun inner pipe, a stainless steel spray gun outer pipe and a ceramic protection layer of the stainless steel spray gun outer pipe. The stainless steel spray gun outer pipe covers the stainless steel spray gun inner pipe, and the stainless steel spray gun outer pipe and the stainless steel spray gun inner pipe are in hollow structures. By means of structural design that the stainless steel spray gun outer pipe in the hollow structure covers the stainless steel spray gun inner pipe in the hollow structure, overhigh temperature of the spray gun can be prevented, and strength of the stainless steel pipes are improved; by the ceramic protection layer of the stainless steel spray gun outer pipe, the spray gun can be protected from friction of materials; due to the fact that high temperature resistance and abrasion resistance of the ceramic protection layer are both better than those of the heat-resistant stainless steel pipes, service time of the spray gun for the Maerz kiln can be prolonged, damages are reduced, equipment cost is saved, and benefits are increased.

Description

technical field [0001] The invention has a double-layer protection Maerz kiln spray gun design structure, and is especially suitable for the Maerz kiln spray gun for firing lime in iron and steel enterprises. Background technique [0002] Nowadays, most of the spray guns of Maerz kilns are made of heat-resistant stainless steel tubes. When in use, due to the high temperature in the kiln during the firing process of lime ash, reaching more than 1000 ℃, due to the friction of materials on the spray gun at high temperature, the Heat-resistant stainless steel pipes wear faster, resulting in higher costs. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of rapid wear and short service life of the existing Maerz kiln spray gun, the present invention provides a Maerz kiln spray gun with double-layer protection, which can reduce the wear of the material on the spray gun under high temperature conditions and prolong the service life of the spray gun .
