Description
Technical field
The invention belongs to coke oven spray repair equipment.Be specifically related to a kind of dustproof blowing material suction device of coke oven gun.
Background technology
The pit kiln of producing coke in use for some time, its refractory brick can produce localized delamination because of high temperature ablation, causes the coke oven quality product to descend.The semidrying coke oven gun can spray refractory mortar and go to repair these defectives.Active service spray repairing machine feeder system adopts star material wheel and sealing plate feed.Refractory matter enters from the opening for feed of star material wheel, and the star material wheel of rotation is sealed in the cylindrical cavity of self with refractory matter by means of two sealing plates up and down, and then refractory matter is sent to discharge port.Pressurized air is introduced by the top of discharge port, and the refractory matter that seals in the discharge port is blown into jet pipe, produces at star material wheel sealing area simultaneously to be higher than atmospheric pressure.Two sealing plates expect that with star the upper and lower surface sealing of wheel is to isolate opening for feed and discharge port and to form seal area up and down.Sealing plate constitutes by vulcanized rubber and steel skeleton.When spray repairing machine is worked refractory matter brought into by star material wheel and the sealing plate that weares and teares rubber part.After sealing plate was ground with indenture, pressurized air entered opening for feed and refractory matter is dispelled the dust pollution that causes Working environment aloft from discharge port along indenture.
Summary of the invention
The present invention is intended to overcome above-mentioned technological deficiency, and purpose provides a kind of dustproof blowing material suction device that does not produce dust at opening for feed, can improve the coke oven gun working life.
For realizing above-mentioned task, the technical solution used in the present invention is: the discharge port that the material sucking port of winding-up material suction device is aimed at star material wheel and lower seal plate by transition conduit is installed, and the winding-up material suction device is fixed on the below of the lower seal plate of star material wheel through coupling block; The winding-up material suction device is made of jet pipe, variable capacity atomizer, material sucking port and adapting pipe, end at jet pipe is equipped with variable capacity atomizer, the other end of jet pipe is equipped with the adapting pipe that communicates with the muddy water mixing valve of spray repairing machine, the front end of variable capacity atomizer is 25mm～50mm apart from the medullary ray of material sucking port, and the rear end of variable capacity atomizer communicates with compressed air gas source.
Wherein: the pressure of compressed air gas source is 0.2MPa～0.5MPa; The internal diameter of jet pipe is 20mm～40mm; The internal diameter of variable capacity atomizer is 6mm～15mm; The diameter of material sucking port is 20mm～40mm.
Described variable capacity atomizer is meant that this nozzle is adjustable along the medullary ray position when mounted of jet pipe.
Owing to adopt technique scheme, the present invention's material suction device of will jetting is installed in below the discharge port of star material wheel and lower seal plate, pressurized air original, that sent into by the discharge port top of star material wheel and upper sealing panel changed into by the winding-up material suction device of the lower seal plate below that is installed in star material wheel send into, necessarily form negative pressure in the interval in the inner chamber outflow of jet pipe and at it, can make star expect that the seal area formation of taking turns is lower than the negative pressure state of barometric point by material sucking port at negative pressuren zone.Therefore, refractory matter can not enter in the air because of negative pressure, and the spray repairing machine opening for feed then can not produce the phenomenon that dust fills the air, thereby has the advantages that dustless spray repair also can prolong the coke oven gun working life.
