Description
Technical field
The utility model relates to steel mill vacuum drying oven dip pipe spray repair car spray gun.
Background technology
Vacuum drying oven mainly is made up of several parts of dip pipe, base channel, intermediate channel and top slot, and molten steel enters in the vacuum drying oven in ladle through dip pipe, flows in the ladle through dip pipe in the vacuum drying oven then.What dip pipe was subjected to molten steel washes away, corrodes comparatively serious, takes hot spray repair attended operation usually, repairs the attack sites such as crackle, pit of dip pipe, keeps cast.
Hot spray repair uses special-purpose vacuum drying oven dip pipe spray repair car spray gun to finish.As shown in Figure 2, dip pipe spray repair car is made up of integral support, interior lance tube, outer lance tube, feed system, water supply air feed system, and lance tube, outer lance tube respectively have a cover feed system, water supply air feed system in the existing spray repair car.The spray repair car has two spray guns of inner and outer pipe, but two spray gun operations successively, volume is big, action inconvenience.The last rifle height of inner and outer pipe spray gun is 2.0m, following rifle height is 1.1mm, the inner and outer pipe spray gun housing is 1.45m from spray repair kickstand height, and spray gun upwards rises and relies on the long electric hoist of leading chain of 2m that has of 1 ton of weight that power is provided, and descending relies on the weight of spray gun and gun platform self.Under the normal situation, the upper limit of interior lance tube, outer lance tube spray repair is the height of dip pipe, and interior lance tube can't be sprayed onto the junction of dip pipe and circulation pipe.
When needing the spray repair operation, connect the airduct and the water pipe of interior lance tube, outer lance tube, adjust the pressure size, the spray repair car is reached the spray repair position, start outer lance tube remote controller and carry out the outer tube spray repair, after the spray repair, pipe spray repair in the lance tube remote controller is carried out in starting, interior lance tube can't be sprayed onto the junction of dip pipe and circulation pipe, and operating procedure is loaded down with trivial details.Spray gun rifle mouth discharging opening is a level, and gunning refractory contacts with dip pipe is vertical, and gunning refractory bounce-back waste is bigger.Simultaneously, spray repair car two cover feed systems, maintenance cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of flexible movements, convenience, realizes that a spray gun reaches inside and outside spray repair, and spray repair is to circulation pipe, and the high vacuum drying oven dip pipe spray repair car spray gun of gunning material utilization rate.
Described vacuum drying oven dip pipe spray repair car spray gun, comprise rifle, following rifle, feed pipe, gun platform, gun platform is positioned at the lower end of rifle down, be fixed on the support by supporting wallboard, between feed pipe and following rifle, be provided with the mixed once blast pipe, be provided with secondary mixing blast pipe between last rifle and the following rifle, the top of last rifle is a nozzle, it is characterized in that: only establish a spray gun, this spray gun has feed pipe from the bottom to top successively, gun platform, the mixed once blast pipe, following rifle, secondary mixing blast pipe, last rifle, nozzle, described nozzle has the elevation angle that is tilted to, with the angle of last rifle vertical line be 30 °-60 °.
Described gun platform links to each other with the electric hoist of being located at spray repair car roof by leading chain, is provided with telescopic guiding support bar between gun platform and support.
The distance of described gun platform and support is 0.75 meter, 1.6 meters of last rifle length, and following rifle length is 2.2 meters.
Compared with prior art, technical scheme of the present invention has following advantage:
1, the system that simplifies the operation only needs to install a cover airduct and a water pipe in the operating process.
2, reduce equipment loss, a car spray repair car only needs cover feed system, water supply air feed system and a spray gun, has saved material cost, reduces the plant maintenance workload.
3, change the height of upper and lower rifle, make gunning refractory and water fully mix in the rifle down.
4, increased the height of spray gun, the effective spray repair height of spray gun is brought up to 1.4m by 0.7m, and the effective depth of spray repair, area increase, the direct attack sites of spray repair circulation pipe, the service life of raising base channel and dip pipe.
4, change the angle of spray tip, improve the adhesive rate of gunning refractory, reduced the waste of gunning refractory.
5, increase by two telescopic guiding support bars, the teeter of having stopped spray gun and gun platform effectively.
6, simple in structure, easy to operate, practical, safety coefficient is big.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is existing spray repair bassinet structure schematic diagram.
Among the figure: the 1-nozzle, the last rifle of 2-, 3-secondary mixing blast pipe, rifle under the 4-, 5-mixed once blast pipe, the 6-feed pipe, the 7-support, 8-leads chain, the 9-gun platform, the 10-feed appliance, the telescopic guide post of 11-, 12-supports wallboard, 13-electric hoist.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: vacuum drying oven dip pipe spray repair car spray gun as shown in fig. 1, gun platform is positioned at the lower end of rifle down, be fixed on the support 7 by supporting wallboard 12, between feed pipe and following rifle, be provided with mixed once blast pipe 5, be provided with secondary mixing blast pipe 3 between last rifle and the following rifle, the top of last rifle is a nozzle 1, only establish a spray gun, this spray gun has feed pipe 6 from the bottom to top successively, gun platform 9, mixed once blast pipe 5, following rifle 4, secondary mixing blast pipe 3, last rifle 2, nozzle 1, described nozzle 1 has the elevation angle that is tilted to, with the angle of last rifle vertical line be 30 °-60 °.After changing the angle of spray tip, improve the adhesive rate of gunning refractory, reduced the waste of gunning refractory.
Owing to only establish a spray gun, simplify the structure, it is more flexible to operate.Because two covers of prior art are as the inside and outside spray gun of inner and outer pipe spray repair system material spray simultaneously, yet but need two cover feed systems, two cover airduct and water pipes, make structure complicated, improved cost, therefore reduce equipment loss after the utility model simplification system, saved material cost.
Described gun platform 9 links to each other with the electric hoist 13 of being located at spray repair car roof by leading chain 8, is provided with telescopic guiding support bar 11 between gun platform 9 and support 7.Guide post is formed by adorning telescopic cylinder in 4.Increase by two telescopic guiding support bars, the teeter of having stopped spray gun and gun platform effectively.
Described gun platform 9 is 0.75 meter with the distance of support 7,1.6 meters of last rifle 2 length, and following rifle 4 length are 2.2 meters.Prolong the height of rifle down, the height of following rifle is increased to 2.2 meters by 1.1 meters, prolongs the mixed once time, makes gunning refractory and water fully mix in the rifle down.
Owing to increased the height of spray gun, effective spray repair height of spray gun is brought up to 1.4 meters by 0.7 meter, and the effective depth of spray repair, area obtain increasing, the direct attack sites of spray repair circulation pipe, the service life of raising base channel and dip pipe.
