Description
Technical field
The utility model is related to the explosion-protection equipment in a kind of drying equipment of pelletizing more particularly to a kind of high temperature pressure relief devices.
Background technology
Granulating drier is the indispensable equipment in the fields such as pharmacy, food, feed, chemical industry, electric power, granulating drier
Operation principle is usually material particle fluidized state in a ring in drying receptacle, by the heating preheating of air by purification
And mixing, binder solution is atomized and is sprayed into, makes particle buildup into the granule containing adhesive, then under the action of hot-air, is rolled into a ball
Moisture constantly evaporates in grain, and adhesive, this process constantly repeats, and forms preferable, uniform more micropore spherical particles.
Granulating drier pressure and temperature during to dry materials is important parameter index, to some oil-containings, sugar content
The stronger temperature of charge of higher and thermal sensitivity cannot be excessively high, can only increase pressure.Drying equipment internal gas, dust or other
The volume expansion at a higher pressure of object mixture, easily explodes, therefore explosion-protection equipment is not in drying equipment of pelletizing
It can lack.
Patent CN203230908U discloses a kind of explosion-proof valve, and simple in structure, compact appearance is compact, can facilitate and be installed
It at the air inlet and air outlet of drying machine, is controlled when valve body is closed rapidly without any external force, is suitble to gas, dust and biology
The burning or explosion of body mixture so that the work that drying machine in a high voltage state still can be safe and reliable.
But in the moment of gas, dust either burning or the explosion of organism mixture, in addition to generate high pressure it
Outside, high temperature can be also generated, even if explosion-proof valve can stop the flowing of gas, but as temperature increases, circulation duct is typically all
The good problem of heat, can equally bring larger hidden danger.Also, as temperature increases, the pressure of gas constantly increases, if too late
When pressure release, the risk of subsequent explosion can be caused, though explosion can be obstructed, equally bring harm.
Invention content
It is an object of the invention to：For cannot obstruct temperature existing for above-mentioned explosion-proof valve and bring since temperature raises
Caused by air pressure becomes larger the problem of the risk of subsequent explosion, the utility model provides a kind of high temperature pressure relief device.
The technical solution adopted by the present invention is as follows：
A kind of high temperature pressure relief device including guide rod and is used to support the supporting rod of guide rod, and the supporting rod is slided with guide rod
It is dynamic to connect, water feed apparatus and pressure relief device are provided on the supporting rod, supporting rod both ends end is provided with support plate, described
Water feed apparatus is including positioned at the buckle with spring function at both ends in supporting rod and on the inside of support plate and being buckled matched
Card slot, is provided with inlet valve above the card slot of lower end, and the pressure relief device is included between the card slot of upper end
Openable relief valve.
Preferably, the inlet valve includes sealing plate, the spring above sealing plate, the cross-sectional area of the sealing plate
More than the cross-sectional area of buckle, the cylinder a sides are connected with water inlet pipe.
Preferably, the relief valve includes the baffle that is tightly connected with card slot and the cylinder b between baffle, described
Baffle is connected with the outlet valve of support plate.
Preferably, the cylinder b connection baric systerms b.
Preferably, it is fixedly installed cylinder c below the buckle.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The utility model is by setting water feed apparatus and pressure relief device, after supporting rod, which is moved to side, blocks runner pipe,
Buckle and pocket matches, while be buckled and push inlet valve so as to open inlet valve, inlet valve conveys atomization to hollow supporting rod
The moisture of shape, until the pressure of inlet valve stops when equal with the pressure of supporting rod.When the water in supporting rod is heated increase
During pressure, pressure relief device is pushed to discharge the pressure in supporting rod, while discharge the pressure in runner pipe, moisture is in heated heel row
Go out, heat can be avoided to continue to propagate by fluid hose with a large amount of heat, while vapour pressure is also released while release
The pressure in runner pipe has been put, has avoided happening since heated caused pressure is constantly increased, reduces subsequent explosion
Risk really plays explosion-proof effect.

Specific embodiment
It elaborates with reference to Fig. 1 to the present invention.
Embodiment one：
As shown in Figure 1, a kind of high temperature pressure relief device, including guide rod 10 and the supporting rod 9 of guide rod 10 is used to support, it is described
Supporting rod 9 is slidably connected with guide rod 10, and water feed apparatus and pressure relief device, 9 both ends of supporting rod are provided on the supporting rod
End is provided with support plate 2, and the water feed apparatus includes being located at the buckle 7 with spring function at both ends in supporting rod 9 and is located at
2 inside of support plate and 7 matched card slots 6 of buckle are provided with inlet valve 3, the pressure release dress above the card slot 6 of lower end
It puts including being located at the openable relief valve 4 between the card slot 6 of upper end.
The present embodiment is blocked by setting water feed apparatus and pressure relief device when supporting rod 9 is moved to side band seal valve 8
After runner pipe 1, buckle 7 is matched with card slot 6, while is buckled and 7 is pushed inlet valves 3 so as to open inlet valve 3, and inlet valve 3 is to hollow
