When adopting technique scheme, added by Gunning refractory in material bin, open feed valve, Gunning refractory enters in batch can, then closes feed valve; Control steam supply valve and enter high pressure gas, because air-supply duct is communicated with batch can, injector respectively, so a road gas enters batch can, pressure increase in batch can, Gunning refractory in batch can is pressed to the outlet bottom batch can, and the rotor of feeding structure rotates under the drive of motor, and periphery of rotor surface is provided with blade vertically, so can continue to be taken out of by Gunning refractory in injector, Gunning refractory is taken out of from spray tube by another road gas of air-supply duct.
The present invention is provided with feeding structure bottom batch can, this feeding structure is using motor as discharging power, by establishing vaned rotor turns, the Gunning refractory bottom batch can is continued to take out of in injector, compared with existing spray repairing machine, become passive discharging into initiatively discharging, so, there will not be the situation of blocking in discharging process.In addition, the load of Gunning refractory just can be controlled by the rotating speed of rotor, and in spray repair process, discharging is more even.
Further, described blade stirs the side indentation of Gunning refractory, and the pressure in batch can is higher, so the Gunning refractory bottom batch can is more closely knit, more closely knit Gunning refractory, in agitation, easilier stirs loose by jagged blade, and delivers in injector.
Further, described rotating shaft is connected by bearing with between Connection Block, and the mode that bearing connects effectively can reduce the wearing and tearing between rotating shaft, Connection Block.
Further, described rotating shaft both sides are equipped with mechanical seal cover, and Gunning refractory is generally pulverous particle, being just easy to cause bearing damage, arranging mechanical seal cover and can prevent Gunning refractory from entering bearing, effectively protecting bearing once enter bearing.
Further, described upper and lower pipe connecting is flare form, and one end that both openings are little is communicated with the through hole of Connection Block, and upper pipe connecting enlarging one end is connected with bottom batch can, and the Gunning refractory in batch can more easily enter in pipe connecting; And enlarging one end of lower pipe connecting is connected with injector, can be entered in injector more easily by the Gunning refractory that rotor draws.
