Description
Technical field
The present invention relates to a kind of cooling device, the side plate cooling device of chain grate boiler, belongs to boiler technology field specifically.
Background technology
In prior art, chain grate boiler generally adopts both sides air intake.In the time that chain grate boiler normally moves, the red-hot sweep of gases of high temperature in stove the sealing block in fire grate, and heat is passed to the shelf being placed on sealing block and column, and shelf is passed to heat on outer panel.When after boiler operatiopn a period of time, outer panel from front to back just can be hot, and the distortion of turning white of burning, not only affects boiler product outward appearance, and a large amount of heats is wasted, and boiler thermal output is reduced.Along with deepening continuously of national energy-saving emission reduction work, how to reduce the every loss in boiler combustion process, improve boiler efficiency, reduce boiler oil consumption, the outer plate surfaces temperature that can guarantee again boiler product is lower than 50 degree of national requirements, problem that must comprehensive consideration when having become boiler design person and designing boiler product.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of side plate cooling device of chain grate boiler, chain grate boiler two outer panels that can effectively prevent both sides air intake pattern from front to back outer surface hot, turn white, yielding phenomenon, the biside plate hull-skin temperature that has effectively solved boiler is too high, the excessive problem of loss of scattering and disappearing.
According to technical scheme provided by the invention, the side plate cooling device of chain grate boiler comprises cooling air channel, it is characterized in that: cooling air channel front end bottom connects first air compartment air channel by first air compartment tube connector, cooling air channel rear end lower connects last air compartment air channel by last air compartment tube connector.Described cooling air channel comprises the fire grate shelf that is positioned at top, and before and after fire grate shelf, both sides connect respectively interior plate and outer panel sealing, are provided with the sealing of lower seal plate between interior plate and outer panel, and the left and right sides of fire grate shelf connects respectively left shrouding and the sealing of right shrouding.Described last air compartment tube connector one end is connected with interior plate, on interior plate, is provided with air regulating port with last air compartment tube connector junction, and air regulating port place is provided with air register track, and air register is slidably connected in air register track.
Further, between interior plate and fire grate shelf, be provided with sealing block.
Further, on air register, connect adjusting rod.
Further, lower seal plate comprises multiple equally distributed crossbeams and is connected to the lower connecting plate between crossbeam.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and floor space is little, is easy to arrange; Low cost of manufacture, convenient maintenance and replacement; Effectively prevent that outer panel from burning from front to back after boiler operatiopn hot, the situation of the distortion of turning white occurs; In guaranteeing the required air quantity of burning, absorb the heat that is lost to the radiation loss in atmosphere originally, make boiler efficiency be able to further raising, the work that national energy-saving is reduced discharging to reduction energy loss is fulfilled.

The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 4, the present invention mainly comprises cooling air channel 1, and cooling air channel 1 front end bottom connects first air compartment air channel 2 by first air compartment tube connector 4, and cooling air channel 1 rear end lower connects last air compartment air channel 3 by last air compartment tube connector 5.
Described cooling air channel 1 comprises the fire grate shelf 6 that is positioned at top, and fire grate shelf 6 both sides, front and back connect respectively interior plate 12 and outer panel 13 seals, and between interior plate 12 and fire grate shelf 6, are provided with sealing block 11.Between interior plate 12 and outer panel 13, be provided with lower seal plate 18 and seal, lower seal plate 18 comprises multiple equally distributed crossbeams 8 and is connected to the lower connecting plate 7 between crossbeam 8.The left and right sides of fire grate shelf 6 connects respectively left shrouding 9 and right shrouding 10 seals.
Described last air compartment tube connector 5 one end are connected with interior plate 12, on interior plate 12, be provided with air regulating port 17 with last air compartment tube connector 5 junctions, air regulating port 17 places are provided with air register track 14, and the air register 15 that is slidably connected in air register track 14, connects adjusting rod 16 on air register 15.In the time of work, the position of moving air register 15 by promoting adjusting rod 16, thereby the size that regulates air register 15 to open, and then regulate the required air quantity of burning.
Operation principle of the present invention is: when work, the cold wind getting off from ground enters each air compartment air channel, not directly to enter fire grate below but upwards enter cooling air channel 1 by last air compartment air channel 3 and be used for the cold wind of cooling side plate, frontly do not arrhea and moving constantly wash away outer panel 13 and act on to reach cooling outer panel 13 through cooling air channel 1 by backward, after cooling air channel 1, absorb the heat outwards distributing in stove and heated wind proceeds to behind first air compartment air channel 2, the wind after preheating has been sent into fire grate below and participate in burning.The fuel burnouting as wrecked need enter fire grate below from 3 air-supplies of last air compartment air channel, can start air register 15, thereby the size that regulates air register 15 to open by the position of mobile air register 15, the wind that participates in burning just can enter fire grate below and fill into burning wind, has strengthened burning of fuel.The invention enables the utilization rate in the last air compartment air channel 3 originally seldom using to be improved, in the situation that not affecting burning, make outer panel obtain good cooling, reduce the heat radiation of boiler and contributed mistake, improve boiler efficiency, make the operation that boiler product can stability and safety, for enterprise is that country brings considerable economic benefit.
