Description
Technical field
The utility model relates to a kind of air bubble, relates in particular to a kind of high-temperature resistant air bubble special for cement.
Background technology
In the last few years, along with the further raising of Construction of Civil Engineering requirements for qualitys such as building, road and bridge, also more and more higher to the requirement of cement mark, the label of cement is high more, its firing temperature is just high more, and the temperature that is stored in behind the cement kiln discharge that bakes in the feed bin is also quite high.High-temperature material or moisture in the feed bin hopper can instead enter the pneumatic release assembly of storage tank in-to-in, because shockproof mount is that rubber or plastics are made, so just may cause piston and shockproof mount to cause in various degree fusing, influence the normal operation of piston, also influence simultaneously the normal operation of other parts of air bubble, just need manually be easy to maintenance and repair and cleaning, time-consuming taking a lot of work; In addition, the jet pipe of air bubble is horizontally disposed with in the cement silo hopper, and the setting of this structure causes the block clearing effect of air bubble when spraying block clearing bad, also can often occur stopping up.
The utility model content
The utility model provides the high-temperature resistant air bubble special for cement of a kind of parts reliable operation, good blocking cleaning effect in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: high-temperature resistant air bubble special for cement, comprise storage tank, built in gas tank has pneumatic release assembly, the relative both sides of storage tank periphery level respectively are provided with air inlet pipe and freeing pipe, and pneumatic release assembly is between air inlet pipe and freeing pipe, and the air inlet pipe opening part is provided with electromagnetic valve, air inlet pipe is fixedly connected with jet pipe, and the spout place of described jet pipe bends setting downwards.
Described pneumatic release assembly comprises gun tube, the gun tube outside is provided with cylindric support by support ring, be provided with the cylinder coaxial in the support with gun tube, cylinder is provided with pore, cylinder one end is provided with closure plate, the closure plate inboard is provided with the spring set collar, be provided with piston in the cylinder, piston one end cooperates with the closure plate roof pressure by retracing spring, piston other end shutoff gun tube port, and the gun tube other end is connected with freeing pipe, closure plate central authorities are provided with through hole, electromagnetic valve is positioned at the through hole outside, and retracing spring is positioned at spring set collar inside, and spring set collar outside is provided with damping spring.
Described piston circumference is provided with twice High Temperature High Pressure oil-free lubrication piston ring.
Length when described damping spring is lax is greater than the length of spring set collar.
After adopting said structure, the injection orifice that jet pipe is positioned at cement silo is provided with down, the block clearing better effects if; Damping spring replaces shockproof mount, has not only improved damping effect, even the high-temperature material in the feed bin hopper or moisture is counter enters in the storage tank can not injure damping spring yet; The piston circumference is provided with twice High Temperature High Pressure oil-free lubrication piston ring, guarantees sealing and pressurized air better effects if; Length when damping spring is lax prevents piston slap to the spring set collar greater than the length of spring set collar, guarantees that damping spring is in good working order all the time; The fault of blowing out that the utility model is simple in structure, reduced air bubble has prolonged service life of air bubble, improves the reliability of equipment package, thereby is good social benefit and the economic benefit of enterprise's creation.

Fig. 2 is the structural representation of the pneumatic release assembly in the middle of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, high-temperature resistant air bubble special for cement of the present utility model, comprise storage tank 1, be provided with pneumatic release assembly 2 in the storage tank 1, the relative both sides of storage tank 1 periphery level respectively are provided with air inlet pipe 3 and freeing pipe 4, and pneumatic release assembly 2 is between air inlet pipe 3 and freeing pipe 4, and air inlet pipe 3 opening parts are provided with electromagnetic valve 5, air inlet pipe 3 is fixedly connected with jet pipe 6, and spout 7 places of jet pipe 6 bend setting downwards.Pneumatic release assembly 2 comprises gun tube 8, gun tube 8 outsides are provided with cylindric support 10 by support ring 9, be provided with the cylinder 11 coaxial in the support 10 with gun tube 8, cylinder 11 is provided with pore 12, cylinder 11 1 ends are provided with closure plate 13, closure plate 13 inboards are provided with spring set collar 14, be provided with piston 15 in the cylinder 12, piston 15 1 ends cooperate with closure plate 13 roof pressures by retracing spring 16, piston 15 other end shutoff gun tubes 8 ports, gun tube 8 other ends are connected with freeing pipe 4, and closure plate 13 central authorities are provided with through hole 17, and electromagnetic valve 5 is positioned at through hole 17 outsides, retracing spring 16 is positioned at spring set collar 14 inside, spring set collar 14 outsides are provided with damping spring 18, and the length when damping spring 18 relaxes is greater than the length of spring set collar 14, and piston 15 circumference are provided with twice High Temperature High Pressure oil-free lubrication piston ring 19.
When work is used, the desired location is provided with built-in fitting 21 on bin wall 20 earlier, by built-in fitting 21 bracing frame 22 is set, bracing frame 22 is welded by angle steel, storage tank 1 is placed on the bracing frame 22, air inlet pipe 3 and freeing pipe 4 on the storage tank 1 are horizontally disposed with, and be close to bin wall 20 bending downwards and be provided with at spout 7 places of jet pipe 6.Because the effect roof pressure piston 15 shutoff gun tubes 8 of retracing spring 16, storage tank 1 enters the inner chamber of storage tank 1 by pore 12 when inflated condition, guarantees that the pressure at piston 15 two ends keeps balance, and at this moment, air bubble is in arm-to-arm.When needs are opened fire with artillery, start electromagnetic valve 5, gas in the cylinder 11 is discharged suddenly, piston 15 two ends form difference of pressure, storage tank 1 in-to-in high pressure gas promote piston 15, open the opening of gun tube 8, the pore 12 on the piston 15 airtight cylinders 11 can not enter in the cylinder 11 gas in the storage tank 1 simultaneously.Just by gun tube 8, the material rapid release of freeing pipe 4 in cement silo, this has just played the block clearing mediation effect to cement silo to high pressure gas in the storage tank 1.In this process; because the powerful propelling thrust of gas makes piston 15 retreat with high speed; the setting of damping spring 18 is unlikely to hit on spring set collar 14 piston 15 to be hit to be split or crashes, and plays the effect of protection piston 15, guarantees that simultaneously retracing spring 16 is not compressed by ultralimit and lost efficacy.After high pressure gas discharged suddenly, when storage tank 1 put on the air, high-temperature gas, powder material or steam can instead enter in the cylinder 11 in the feed bin, and damping spring 18 can not lose efficacy under the condition of high temperature yet, and piston ring 19 waits other parts also can normal operation.
