Abstract
The utility model belongs to the improvement, especially a modified gun pipeline spray repair device of steel mill converter refractory material gun structure, include setting up the spray repair pipe on the discharge gate of storage tank lower part, the spray repair pipe is being connected to the pneumatic control pipe network, and it is managed in the decurrent spray repair of standing upright, and the port is closed through sealing the flange board down, setting up the side and exporting on the pipe wall of spray repair pipe, and side spray repair pipe and the spray repair pipe connected on the side exports are perpendicular, and the pneumatic tube is connected with the spray repair pipe, and the spout of pneumatic tube and the import that the side spray repair was managed are corresponding. Its is rational in infrastructure, and it is reliable to operate steadily, can reduce the erodeing of spray repair pipe, and the life of extension pipeline improves the gun and to the spray repair effect of dip pipe, reduces the pollution to the environment.
Description
Technical field
The utility model belongs to the gun pipeline mending device of the improvement, particularly a kind of improvement of steel mill converter refractory material gun structure.
Background technology
When steelwork converter production line refining furnace RH stove vacuum tank is smelted, dip pipe (suppressed by resistance to material and form) is immersed in molten steel for a long time, causes certain scaling loss to dip pipe, so must carry out the spray repair of resistance to material to dip pipe timing.Can gun normally use, and directly affects life-span and the Production requirement of dip pipe.
RH stove gun system equipment is summarized
One, gun transports pipeline by storage tank body (charging valve, stirring unit, operated pneumatic valve) and forms, and operation principle is as follows:
Add refractory material by charge door, reinforced valve closing, sealing tank body, carrying out gas pressurized to continuing in tank, and stirring unit operates, and sweep gas pipeline works, and pneumatic operated valve is opened simultaneously, outwards transports the powder of resistance to material by pipeline, carries out spray repair process to dip pipe.
Two, the defect existed in equipment operation process
Gun spray repair uses in gunning refractory certain powder particle.Washing away 90o elbow in long spray repair process, cause pipeline Fast Wearing rotten, gunning refractory leaks, and affects spray repair process.Only have shutdown to carry out changing or soldering process, affect the spray repair work to dip pipe.
Utility model content
The purpose of this utility model is the gun pipeline mending device providing a kind of improvement, and it is rational in infrastructure, operates steadily reliable, washing away spray repair pipe can be reduced, extend the service life of pipeline, improve the spray repair effect of gun to dip pipe, reduce the pollution to environment.
The purpose of this utility model is achieved in that a kind of gun pipeline mending device of improvement, the discharging opening being included in storage tank bottom arranges spray repair pipe, air pressure controls pipe network and is connected to spray repair pipe, uprightly downward its lower port of spray repair pipe is closed by blind flange plate, the tube wall of spray repair pipe arranges side outlet, it is vertical with spray repair pipe that the side spray that side outlet connects mends pipe, and pneumatic tube is connected with spray repair pipe, and the spout of pneumatic tube is corresponding with the import that side spray mends pipe.
The side opening that the utility model is arranged at spray repair tube wall is connected to side spray and mends pipe, it is vertical with spray repair pipe that side spray mends pipe, corresponding with the import that the spout of the pneumatic tube that spray repair pipe is connected and side spray mend pipe.In the process of air pressure material conveying, form the friction between gunning refractory, reduce gunning refractory washing away pipeline, extend the life-span of pipeline.
The good effect that the utility model produces:
1, to use two weeks just to wear and tear in the past rotten for new gun pipeline, just must soldering use.Maximum use just must change elbow of pipeline in 1 month.After transformation, few through pipeline wearing and tearing on probation, spray repair process is unobstructed, improves the effect of spray repair dip pipe, decreases soldering and the replacing of pipeline;
2, eliminate pipeline breakage and leak material, improve gun operating efficiency; Reduce dust environmental pollution;
3, the spray repair work to dip pipe can be carried out at any time;
4, reduce a staff labour intensity.If the mouth of pipe is blocked by material, flange capping cleaning pipeline can be opened.
The utility model is rational in infrastructure, achieves and operates steadily reliably, reduce washing away spray repair pipe, extend the service life of pipeline, improve the spray repair effect of gun to dip pipe, reduce the pollution to environment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of gun pipeline mending device of improvement, as shown in Figure 1, the discharging opening being included in storage tank 1 bottom arranges spray repair pipe, air pressure controls pipe network and is connected to spray repair pipe, uprightly downward its lower port of spray repair pipe 2 is closed by blind flange plate, and the tube wall of spray repair pipe 2 arranges side outlet, and it is vertical with spray repair pipe 2 that the side spray that side outlet connects mends pipe 3, pneumatic tube is connected with spray repair pipe 2, and the spout of pneumatic tube is corresponding with the import that side spray mends pipe.
Claims (1)
