Abstract
Disclosed is a spraying device of anti-sticking and fireproof coating of a converter oxygen lance, which belongs to the field of spraying devices and comprises a spraying ring arranged above a nitrogen sealing port, a motor, a pump, a high-pressure air supply and a coating box. A pipeline connecting the spraying ring with the pump is in parallel connection with a high-pressure air supply pipeline which is communicated with the high-pressure air supply. The utility model is characterized in that a motor shaft is connected with a reducer, the reducer is connected with a stirring propeller, and the pipeline connecting the pump ring with the pump is in series connection with a throttle valve, a one-way valve and a hydraulic electromagnetic valve. The utility model has the advantages of uniform spraying, convenient operation, safety and reliability, greatly prolonging service life of the oxygen lance, reducing production costs and reducing labor intensity of labors.
Description
Technical field
The utility model belongs to the spray equipment field, the spray equipment of the antiseized fireproof coating of particularly a kind of converter oxygen gun.
Background technology
Since the production characteristics of converter self, the problem of converter oxygen gun surface ubiquity bonding slag.The bonding slag can cause when serious the oxygen rifle carry plug for outlet not (because of the cold steel of sticking rifle be stuck in nitrogen seal can't get out), just cause stove not fascinate this moment, the influence blowing is operated; Secondly, can destroy the counterweigh of oxygen rifle transmission system when seriously gluing rifle, even can make the oxygen rifle can't promote (the oxygen rifle just can't promote when bonding slag weight adds the deadweight of oxygen rifle greater than counterweight weight).ZL03254273.9 discloses a kind of spray equipment of oxygen rifle protective coating; this device can be wiped slag off easily, but this device does not have agitating function, no self-protection function; and when the pipeline local pressure overloads, do not have self-pressure release function, thereby the serviceability of this device is reduced greatly.
The utility model content
At the ubiquitous bonding slag problem in converter oxygen gun surface, the utility model provides the spray equipment of the antiseized fireproof coating of a kind of converter oxygen gun, makes the fireproof coating spraying evenly, is convenient to operation.
The technical solution of the utility model is achieved in that the spray equipment of the antiseized fireproof coating of a kind of converter oxygen gun, comprise and be arranged on spray ring, motor, pump, high-pressure air source and the coating case that nitrogen seals the top, high-pressure air source pipeline in parallel on the pipeline that spray encircles with pump connects, the high-pressure air source pipeline communicates with high-pressure air source, motor shaft links to each other with decelerator, decelerator is connected with the agitating auger oar, can guarantee that coating is in even admixture when using; Series throttle, check valve and hydraulic buttery valve on the pipeline that spray encircles with pump connects.
Overflow valve, Pressure gauge and a pressure switch in parallel in described spray ring and the pipeline that pump connects.
On the described high-pressure air source pipeline check valve, air-operated solenoid valve and stop valve are housed.
Described between choke valve and check valve overflow valve in parallel.
The beneficial effects of the utility model are: the utility model spraying evenly is convenient to operation, and is safe and reliable, the life-span that can significantly improve the oxygen rifle, reduce production costs, and alleviate working strength of workers.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 spray ring, 2 oxygen rifles, 3 nozzles, 4 air-operated solenoid valves, 5 stop valves, 6 high-pressure air source, 7 overflow valves, 8 decelerators, 9 agitating auger oars, 10 choke valves, 11 check valves, 12 Pressure gauges, 13 pressure switches, 14 pumps, 15 motors, 16 coating cases.
The specific embodiment
The utility model is used for converter oxygen gun, as shown in Figure 1.Position above the nitrogen of oxygen rifle seals is equipped with spray ring (1), and for the ease of installing, spray ring (1) is by two semi-circular compositions, and spray ring (1) installed inside has nozzle (3), and nozzle (3) quantity is 6, evenly distributes.Check valve A1 and check valve A2 are arranged in the pipeline, can prevent that the flow direction source of the gas from can prevent the gas flow pump again.Coating is supplied with on the road and is in series with a choke valve (10), can regulate the flow of protective coating, can guarantee that spraying fully again can economical with materials.
Have 3 2/2-way magnetic valves in the system, air pressure electromagnetic valve B1 and hydraulic buttery valve B2, hydraulic buttery valve B3, coating is supplied with Pressure gauge in parallel (12) and pressure switch (13) on the road, Pressure gauge (12) can show the pressure on the coating supply road, and pressure switch (13) can connect alarm, when the obstruction of supply road causes hypertonia, pressure switch (13) action, alarm sounds, and should check whole system this moment, fixes a breakdown.Be not damaged in order to protect pump (15) and to supply with the road, overflow valve C1 and overflow valve C2 be installed, automatically unloading in the system.
Motor (14) and pump (15) constitute the supply source of protective coating, and certain pressure is provided, and decelerator (8) the drive agitating auger oar (9) of series connection rotates under the motor shaft simultaneously, carries out stirring operation, and protective coating is evenly exported.
When oxygen rifle (2) descends (or lifting); start working; according to program, motor (14) entry into service, and because magnetic valve B1 and magnetic valve B2 are normally closed; magnetic valve B3 is for often leaving; so the time do not have protective coating and gases at high pressure enter shower nozzle, protective coating returns coating case (16) via magnetic valve B3, at this moment; agitating auger oar (9) is started working, and begins to stir.After a period of time; magnetic valve B1, magnetic valve B2 and magnetic valve B3 are in succession; magnetic valve B1 and magnetic valve B2 open; magnetic valve B3 closes; pump (15) is sent to annular nozzle (1) and nozzle (3) from coating case (16) via magnetic valve B2, check valve A2, choke valve (10) with protective coating; pressure-air mixes with protective coating mutually via stop valve (5), magnetic valve B1, check valve A1 in addition; protective coating can nebulize and spray from nozzle (3) like this; be sprayed at uniformly on the oxygen rifle (2); after oxygen rifle (2) has all sprayed, stop spraying by programme-control.
When stopping to spray; magnetic valve B2 and magnetic valve B3 cut off the power supply in succession; protective coating returns coating case (16) via magnetic valve B3; at this moment; the protective coating that remains in nozzle (3) mouthful place solidifies because of high temperature; blocked for preventing; after finishing, the each spraying of system do not close magnetic valve B1 immediately; by the automatic washer jet of gases at high pressure (3), high-pressure air source (6) and coating supply source are independently of one another, and spraying is closed the coating supply source earlier after finishing; the high-pressure air source that works independently (6) can make coating residual on the pipeline clean out in case its frozen plug pipeline; auto power off afterwards, magnetic valve B1 closes, and motor (14) is shut down.
