Abstract
The utility model relates to an anti-backfire device of a feeding hole of a boiler. The anti-backfire device is characterized in that an automatic closing switch consisting of a fixed plate and a movable plate is designed in the feeding hole of a feed pipe of the boiler, wherein the fixed plate is mounted above the movable plate and inclines downwards with 30-40 degrees, and the movable plate is fixed below the opposite side of the fixed plate through a hinge and inclines downwards with 40-60 degrees. The area of the fixed plate is 1/4 of the cross section area of the feed pipe, and the area of the movable plate which is fixed below the opposite side of the fixed plate through the spring hinge is greater than 3/4 cross section area of the feeding pipe, which is left by the fixed plate, and is smaller than the whole cross section area of the feeding pipe. A transmission band is arranged above the feeding pipe, one end of the transmission band is positioned above a blanking hole, and the other end is positioned below a feed bin. When backfire is generated in the boiler, the movable plate automatically moves upwards under the action of smoke in the boiler to close with the fixed plate so as to close the backfire, close the feeding hole, block up the smoke from bursting out outwards and prevent the occurrence of fire accidents. The utility model is beneficial to successfully carrying out charging work.
Description
[technical field] the utility model relates to a kind of boiler component, is a kind of fireproof tempering device of boiler feed mouth specifically.
[background technology] is well-known, and boiler often need be added fuel in combustion process, yet in reinforced process, often have the phenomenon that flue gas even flare are outwards emerged, be called later, this tempering phenomenon not only can influence reinforced process and workers'health, also can slattern partial heat energy.
[summary of the invention] has the defective of tempering phenomenon when overcoming existing boiler feeding, and the utility model provides a kind of fireproof tempering device of boiler feed mouth, and tempering phenomenon takes place when avoiding reinforced.
In order to solve its technical problem, the technical solution adopted in the utility model is: in the charging aperture of boiler feed pipe, design is by the auto-closing switch of being made up of fixed head and portable plate, wherein fixed head is installed in the portable plate top, and 30-40 ° inclination arranged downwards, portable plate fixes on the below on fixed head opposite by hinges fixing, and 40-60 ° inclination is arranged downwards; The area of described fixed head is 1/4 of a feed pipe sectional area, and by the fixing portable plate of band spring hinge, feed pipe 3/4 sectional area that its area stays greater than fixed head is less than whole feed pipe sectional area below the fixed head opposite; Be provided with transport tape above feed pipe, an end of this transport tape is positioned at the blanking port top, and the other end is positioned at the feed bin below; When producing tempering in the stove, make portable plate under the effect of inner flue gas of the stove, upwards seal tempering automatically with the fixed head closure.
Compared with prior art, the utility model has following advantage:
Because the utility model is provided with the movable machine of energy auto-closing at the charging mouth of pipe, make portable plate and fixed head closure by spring at ordinary times, can block the interior flue gas of boiler outwards emerges, when needing to feed in raw material, by the deadweight of material with the impulsive force when falling, can open portable plate downwards automatically, allow material fall into feed pipe and flow to pot, if the flue gas impulse force is too big in the boiler, this impulsive force can upwards push away portable plate, with the fixed head closure, make it to close charging aperture, the blocking-up flue gas is outwards emerged, and prevents the generation of fire incident, helps reinforced work safety, carries out smoothly.
[description of drawings] further specifies the utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, feed bin, 2, blanking port, 3, transport tape, 4, fixed head, 5, portable plate, 6, feed pipe, 7, boiler body.
[specific embodiment] is referring to accompanying drawing: the side at boiler body 7 is provided with feed pipe 6, this feed pipe one end is connected with the combustion chamber of boiler body, the other end is a blanking port 2, be provided with fixed head 4 above in blanking port 2, the downward-sloping 30-40 of this fixed head °, its area is 1/4 of a feed pipe sectional area, hinge by the band spring below the opposite of fixed head 4 is fixed with portable plate 5, the area of this portable plate is greater than fixed head, feed pipe 3/4 sectional area that stays, less than whole feed pipe sectional area, above feed pipe 6, be provided with transport tape 3, an end of this transport tape is positioned at the blanking port top, the other end is positioned at feed bin 1 below, during charging, material can be from feed bin, through transport tape, portable plate and enter feed pipe and enter in the boiler body.
Claims (3)
1. the fireproof tempering device of a boiler feed mouth, it is characterized in that: in the charging aperture of boiler feed pipe, design is by the auto-closing switch of being made up of fixed head and portable plate, wherein fixed head is installed in the portable plate top, and 30-40 ° inclination arranged downwards, portable plate fixes on the below on fixed head opposite by hinges fixing, and 40-60 ° inclination is arranged downwards.
2. according to the fireproof tempering device of the described a kind of boiler feed mouth of claim 1, it is characterized in that: the area of described fixed head is 1/4 of a feed pipe sectional area, the portable plate of below the fixed head opposite, fixing by the band spring hinge, feed pipe 3/4 sectional area that its area stays greater than fixed head is less than whole feed pipe sectional area.
3. according to the fireproof tempering device of claim 1 or 2 described a kind of boiler feed mouths, it is characterized in that: be provided with transport tape above feed pipe, an end of this transport tape is positioned at the blanking port top, and the other end is positioned at the feed bin below.
