Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
Embodiment 1
As shown in Figure 1, the present invention provides a kind of multifunctional gas furnace cooling system, including air flue 18;The air flue is set
Be placed in heating furnace liner shell 13 is outer and the position of gluing, sealing circle.In the present embodiment, air flue 18 be located at sealing ring 2 with it is interior
The back side of 3 joint place of gallbladder flange, in the corner of liner flange 3 and liner shell 13, section is by liner flange 3, air flue shell
Body anchor ring 5, air flue back side of shell 7 and liner shell 13 surround.The sealing ring is the sealing ring 2 for sealing fire door 1;
Sealing ring 2 is fitted in the outside of liner flange 3, and contacts with fire door 1, to realize the sealing between fire door 1 and liner shell 13.
The air flue is provided with air inlet 15, gas vent 4 and the venthole 8 being connected to the liner;Use is additionally provided in the air flue
In to have in the gas vent 4 and the venthole 8 and only a kind of change-over switch of unlatching.Air flue 18 (is connected on flange
Contacted with sealing ring 2) achieve the purpose that coolant seal circle 2 by recycling cold air.
It is formed as shown in figure 3, the air flue 18 divides circular passage by partition 17;The air inlet 15 is set to partition 17
Side, the gas vent 4 and venthole 8 are set to 17 other side of partition, and (partition 17 is placed on air inlet 15 and gas vent 4 vertically
Between, 18 section of air flue is blocked completely, so that gas is entered air flue 18 by air inlet 15 and flowed along air flue 18).Air flue shell
Air flue 18 of the body back side 7 by guide groove B9 close to 1 side of fire door blocks, the planform of 7 lower right of air flue back side of shell with lead
It is matched to " Γ " cross-sectional profile of slot B9;It which is provided with blade switch 6 and venthole 8.In the present embodiment, the gas vent
4 opposite sides for being set to the venthole 8 may also set up in remaining specific embodiment in the same side.It should be noted that
There are two guide groove (guide groove A16 and guide groove B9), the guide groove air flue 10 can be led the setting of liner internal symmetry by any
It is formed to slot.
The change-over switch is blade switch 6 or hole switching plate 19.In the present embodiment, using blade switch 6 (referring to figure
3), the width with a thickness of air flue shell inner section of blade switch 6 can or block 8 (this of venthole by rotation blade switch 6
When gas vent 4 open) or block gas vent 4 (at this time venthole 8 open).
As shown in Fig. 2, being provided with exhaust pipe 14 and guide groove air flue 10 in the liner;The venthole 8 is connected to described
Air flue and the guide groove air flue 10;The outlet of the guide groove air flue 10 is set to the opposite side of the exhaust pipe 14, so that folder
Cooling gas with 2 heat of sealing ring enters liner and by way of entire liner (clinodiagonal that its path is liner) discharge.
The guide groove air flue 10 is formed by guide groove B9 and the wall of inner container, section closure.The outlet of the guide groove air flue 10 away from
There is gap between wall surface (in the present embodiment be liner housing rear face 12) from the liner, enables cooling gas from guiding
Slot air passage outlet end 11 enters inside liner shell 13.It is provided with groove profile gap on liner shell 13, make and air flue 18 and leads
Match to the planform of slot B9.
Embodiment 2
As shown in figure 4, the present embodiment the difference from embodiment 1 is that, gas vent 4 is moved to the same plane of venthole 8
(air flue back side of shell 7), the thickness of blade switch 6 does not need identical as the thickness of 18 inner section of air flue at this time.It is opened by blade
6 opening and closings for controlling gas vent 4 and venthole 8 simultaneously are closed, i.e., then close venthole 8 when blade switch 6 opens gas vent 4, are opened
Gas vent 4 is then closed when venthole 8.
The operating method of embodiment 1,2 is as follows: when solid material is dried with heating furnace, heating furnace needs first right first
Solid material in liner shell 13 is heated, this stage cooling system only cools down sealing ring 2, at this time cooling system
The blade switch 6 of system is threaded to venthole 8 and closes and 4 open state of gas vent, and cooling gas enters air flue 18, edge from air inlet 15
Air flue 18 flows to gas vent 4 and is expelled directly out completion cooling.After material heating, need to cool down to material, therefore
Cooling system needs not only coolant seal circle 2 but also cooling material.Blade switch 6 is threaded to the unlatching of venthole 8 at this time and gas vent 4 is closed
State, so that cooling gas enters guide groove air flue 10 from venthole 8 after completing to the cooling of sealing ring 2, then from guiding
Liner shell 13 (lower right corner) is sent at slot air passage outlet end 11.Cooling gas is completed and the heat exchange of material in liner shell 13
It is discharged later from exhaust pipe 14 (upper left corner of liner shell 13), is finally completed the cooling to material in heating furnace.
Embodiment 3
As shown in figure 5, the present embodiment the difference from embodiment 1 is that, blade switch 6 is changed into the hole switching plate of drawing and pulling type
19.Air channel is provided on hole switching plate 19.When pull-out-hole switching plate 19, venthole 8 is not blocked, and hole switching plate 19 blocks
It is cooling in furnace to open on gas vent 4 on liner flange 3 or air flue back side of shell 7;When being pushed into hole switching plate 19, ventilation
Gas vent 4 on slot and liner flange 3 or air flue back side of shell 7 is together with venthole 8 is blocked, cooling in furnace to stop.
The specific operation method is as follows for embodiment 3:
When solid material is dried with heating furnace, first heating furnace need first to the solid material in liner shell 13 into
Row heating, this stage cooling system only cool down sealing ring 2, are pushed into hole switching plate 19, air channel and liner at this time
Gas vent 4 on flange 3 or air flue back side of shell 7 is together with venthole 8 is blocked, and cooling gas enters air flue from air inlet 15
18, gas vent 4, which is flowed to, along air flue 18 is expelled directly out completion cooling.After material heating, need to cool down to material,
Therefore cooling system needs not only coolant seal circle but also cooling material.Pull-out-hole switching plate 19 at this time makes it not block venthole 8,
Orifice plate switch plugging is on the gas vent 4 on liner flange 3 or air flue back side of shell 7, so that cooling gas is completed to sealing
Enter guide groove air flue 10 from venthole 8 after the cooling of circle 2, then is sent into liner shell 13 from guide groove air passage outlet end 11
(lower right corner).Cooling gas completed in liner shell 13 with the heat exchange of material after from exhaust pipe 14 (liner shell 13
The upper left corner) discharge, it is finally completed the cooling to material in heating furnace.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present invention
Within enclosing, then the present invention is also intended to include these modifications and variations.
