The inlet opening 4 is circular and the length of the mixing chamber 5 is greater than the diameter of the inlet opening 4. The length of the mixing chamber 5 is 4 times the diameter of the feed opening 4.
The outlet of oxygen nozzle 3 is located in the mixing chamber intake section 501 below the feed port 4. The air vent 2 is provided just below the inlet of the oxygen nozzle 3.
The mixing chamber 5, the discharge port 6 and the oxygen nozzle 3 are positioned on the same axis.
The diameter of the mixing chamber 5 is 2.3-2.5 times of the diameter of the discharge port 6.
The aperture of the oxygen nozzle 2 is 3mm, the diameter of the mixing chamber 5 is 45mm, and the diameter of the discharge port 6 is 19 mm.
The mixer is made of stainless steel material because of the contact with pure oxygen.
The ceramic welding material suitable for the furnace wall of the coke oven furnace head with the corrosion, pitted surface and crack needs smaller granularity, small jetting capacity and smaller aperture. The ceramic welding repair machine has short horizontal distance and low vertical working height, so that the problem of resistance consumption of mixed materials of oxygen and the ceramic welding repair material during conveying is not considered, and the inner diameters of a material conveying rubber pipe and a welding gun can be smaller than the diameter of a discharge hole of a mixer.
Examples 1,
A5.5 m tamping coke oven is used for treating the walls of the 1 st to 4 th flame paths of a carbonization chamber, a common long stainless steel welding gun is used, the length of the stainless steel welding gun is 4.5m, the length of an external conveying pipe is 10m, and the working distance is ensured to be more than 15 m. Adopt the utility model discloses, 2 aperture 3m of oxygen nozzle, discharge gate 6 (shrink section) hole diameter 19mm, defeated material rubber tube internal diameter 19mm, stainless steel welder internal diameter 16 mm. Under the condition that the oxygen working pressure is 0.3MPa, the suitable spraying capacity of the ceramic soldering machine is 40 kg/h.
The spraying speed, the impact force and the discharge amount of the ceramic welding repair material are reduced in the using process, and the phenomena of blockage and material return of a mixer do not occur in the welding repair process; the output of the mixer is uniform, and the material conveying fluctuation is small; the ceramic welding material is sprayed out from the ceramic welding gun and is uniformly mixed with oxygen, and the ceramic welding material is well combusted. Through observing, use the utility model discloses a ceramic repair welding equipment operation, repair welding face thickness is controlled more easily, and the repair welding layer is generally thinner, and the material burning is abundant simultaneously, and sealing performance can satisfy the operation requirement.
Comparative examples 1,
An existing blender was used (application No. 2018215924294). 5.5 m tamping coke oven, 1 st-4 th flame path furnace wall of the processing carbonization chamber, using a common 6m stainless steel welding gun, the length of a material conveying pipe is 15m, using a traditional injection mixer, the working distance is about 20m, the aperture of an oxygen nozzle is 3m, the diameter of a contraction section hole of the mixer is 8mm, the inner diameter of the material conveying rubber pipe is 25mm, the inner diameter of the stainless steel welding gun is 18mm, the working pressure of oxygen is 0.4MPa, and the injection capacity of the ceramic welding repair machine is about 100 kg/h.
The phenomena of blockage, tempering and material returning of the mixer do not occur in the normal use process, the ceramic welding material is sprayed out from the ceramic welding gun and is uniformly mixed with oxygen, and the ceramic welding material is completely combusted. However, the ceramic welding material is sprayed out of the welding gun under high pressure, high impact force and high discharge amount, the thickness of the welding surface is difficult to control, the welding layer is too thick when the welding time is too long, normal coke oven production is easily affected, the sealing effect is poor when the welding time is too short, the material is not sufficiently combusted, and the welding quality is affected. Although the ceramic welding repair machine can adjust the material conveying amount through parameters such as rotating speed, air source pressure and the like, the adjustable range of equipment parameters is not large due to the limitation of a mixer and materials. Experiments prove that although the discharge amount can be reduced by reducing the feeding amount of the turntable, the pressure and the impact force output by a welding gun cannot be effectively reduced, and the increase of the rebound materials is easy to cause, so that the wall-mounting rate of the materials is reduced, and the welding repair effect is influenced; the oxygen pressure is reduced, the conveying effect of the material cannot be guaranteed, uneven discharging is easily caused, and the quality problems of material half-cooked, insufficient combustion and the like are caused. Therefore, the existing mixer is difficult to repair a thin layer of welding repair on the denudation, pitted surface, crack and the like of the wall of the coke oven.
The example 1 and comparative example 1 controls show that: under the same other conditions, the ceramic welding repair machine has proper jetting capacity, and is very suitable for the situation that a coke oven wall is corroded, pitted surface, cracks and the like and needs to be thinly repaired by one layer; the mixer has no phenomena of blockage and material return; the output material of the mixer is uniform, the ceramic welding material is sprayed out from the ceramic welding gun and is uniformly mixed with oxygen, and the ceramic welding material is completely combusted.
