Abstract
The utility model involves a tool for repairing the leak of the coke oven regenerator. This is a spray gun for repairing the leak of the coke oven regenerator. The utility model is characterized in that spray rod, feed hopper and compressed air leading-in conduit. The spray rod is a pipe. The feed hopper and the compressed air leading-in conduit are provided at the rear part of the spray rod. The compressed air leading-in conduit is in the spray rod. The feed hopper is above the spray rod. The connecting part of the feed hopper exit and the spray rod is behind of the exit of the compressed air leading-in conduit in the spray rod. The axial line of the compressed air leading-in conduit and the axial line of the spray rod coincide with each other. The compressed air blows the gunning material in to the regenerator to seal the regenerator. The spray gun is of easy structure and easy operation and control.
Description
(1) technical field
The utility model relates to a kind of instrument of repairing the coke oven regenerator blowby.
(2) background technology
Coke oven regenerator mainly is made up of the regenerator top space, checker brick, double-edged fine-toothed comb brick and main wall, Dan Qiang, partition wall and envelope wall.Coke oven regenerator plays a part very important in coke oven production, and it is fully used the heat of waste gas, has improved coke oven combustion efficient greatly, has reduced the coke oven energy consumption.But along with the coke oven increase in furnace life, the after-expansion of body of heater causes the coke oven combustion chamber underfeed to add the single wall (partition wall) of regenerator, the main wall blowby of heating gas and air.In case regenerator generation blowby, corresponding flue temperature will descend significantly, havoc normal heat-processed of coke oven and converter life, and influenced coke quality; In addition, also may cause to add heating gas and air short circuit, and burn, not only cause the loss of the energy at positions such as regenerator and horizontal flues, also may cause the high temperature accident when serious and with the coke oven scaling loss, thereby bring very big threat for the safe operation of coke oven.
(3) summary of the invention
The purpose of this utility model is to provide a kind of spray gun of repairing the coke oven regenerator blowby, and this spray gun is blown into Gunning refractory in the regenerator under the pressurized air effect, thereby realizes the sealing to regenerator, and this spray gun structure is simple, and is easy to operate.
The utility model is achieved in that a kind of spray gun of repairing the coke oven regenerator blowby, it is characterized in that: comprise spray boom, hopper, pressurized air ingress pipe, spray boom is a tubulose, hopper and pressurized air ingress pipe are housed at the spray boom rear portion, the pressurized air ingress pipe is sleeved in the spray boom, hopper is contained in the spray boom top, and the hopper outlet slightly leans on the back in the exit of pressurized air ingress pipe in spray boom with the spray boom connection place.
Described pressurized air ingress pipe axis and spray boom axis coincide.
The utility model is to adopt spray gun under the pressurized air effect, and Gunning refractory is blown in the regenerator, realizes the sealing to regenerator.Spray gun comprises spray boom, hopper, pressurized air ingress pipe, hopper and pressurized air ingress pipe are housed at the spray boom rear portion, the hopper outlet slightly leans on the back in the exit of pressurized air ingress pipe in spray boom with spray boom connection place (being opening for feed), so that the negative pressure that compressed air spraying produces can suck the Gunning refractory in the hopper in the spray boom, and under compressed-air actuated promotion, send into and repair sealing in the regenerator.Spray gun structure is simple, and is easy to operate.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of spray gun structure synoptic diagram of repairing the coke oven regenerator blowby of the utility model.
Among the figure: 1 spray boom, 2 hoppers, 3 pressurized air ingress pipes.
(5) embodiment
Referring to Fig. 1, a kind of spray gun of repairing the coke oven regenerator blowby comprises spray boom 1, hopper 2, pressurized air ingress pipe 3.Spray boom 1 is made by a long stainless steel tube.At spray boom 1 rear portion hopper 2 and pressurized air ingress pipe 3 are housed.Pressurized air ingress pipe 3 is a stainless-steel pipe, and it is sleeved in the spray boom 1, and an end stretches out the connection compressed air inlet port, and pressurized air ingress pipe 3 axis and spray boom 1 axis coincide, and pressurized air ingress pipe 3 is welded on spray boom 1 end and is fixed.Hopper 2 is contained in spray boom 1 top, hopper 2 is a conical structure, hopper 2 outlets and spray boom 1 connection place are as opening for feed, opening for feed slightly leans on the back in the exit of pressurized air ingress pipe 3 in spray boom 1, so that the negative pressure that compressed air spraying produces can suck the Gunning refractories in the hopper 2 in the spray boom 1, and under compressed-air actuated promotion, send in the regenerator.
When the regenerator of blowby is carried out spray repair, close the gas valve that leads to the gas regenerator earlier, open the downward modulation port lid, spray boom 1 is passed horizontal flue be inserted to regenerator bottom.For effectively keeping the regenerator internal pressure of sealing, treat that spray gun locates postpone, with ceramic fiber the grate hole is blocked up.Utilize 7kg/cm
2Pressurized air be blown into from the pressurized air ingress pipe 3 of spray gun bottom, form negative pressure in spray boom 1 opening for feed position and suck Gunning refractory, under compressed-air actuated promotion, send in the regenerator, under the effect of pressure reduction, make powder float towards each blowby point, to fill up the fine gap of body of heater, realize sealing to regenerator inside blowby point.
The utility model can be used for repairing coke oven furnace wall cracklin and brickwork joint, has solved the blowby situation of regenerator, improves the coke oven furnace, improves coke quality, reduces the coke oven energy consumption, helps environment protection, and the production of assurance coke oven is carried out smoothly.Spray gun structure is simple, convenient operation and control.
Claims (2)
1. spray gun of repairing the coke oven regenerator blowby, it is characterized in that: comprise spray boom, hopper, pressurized air ingress pipe, spray boom is a tubulose, hopper and pressurized air ingress pipe are housed at the spray boom rear portion, the pressurized air ingress pipe is sleeved in the spray boom, hopper is contained in the spray boom top, and the hopper outlet slightly leans on the back in the exit of pressurized air ingress pipe in spray boom with the spray boom connection place.
2. the spray gun of repairing coke oven regenerator according to claim 1 blowby is characterized in that: pressurized air ingress pipe axis and spray boom axis coincide.
