Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, described ladle online baking device, including the machine being made up of some columns 1 and crossbeam 2
Frame, the roaster lid 3 that two roaster lid fire output holes 12 are set is hung with the crossbeam 2 of frame, in roaster lid 3
On be provided with air hose 4, gas pipe 5, fume pipe 6 and reversal valve 7, the 12 roaster lid at each roaster lid fire output hole
A burner, i.e. the first burner 8 and the second burner 81 are separately installed with body 3, each burner has been respectively communicated with a heat storage,
I.e.：First burner 8 connects the first heat storage 9, and the second burner 81 connects the second heat storage 91, a docking port of the reversal valve 7
Be connected respectively with air hose 4 and fume pipe 6, another docking port of reversal valve 7 respectively with the first heat storage 9 and the second heat storage
91 are connected, and gas pipe 5 is connected with the first burner 8 and the second burner 81 simultaneously, is additionally provided with the bottom of roaster lid 3
The protection cap 10 of the bottom of roaster lid 3 is just enveloped, two and roaster lid fire output hole are provided with protection cap 10
12 corresponding protection cap fire output holes 11；In the present embodiment, the protection cap 10 hangs the crossbeam 2 in frame by chain 13
On, it is more convenient so to dismount protection cap 10；In the present embodiment, protection cap and the connected mode of roaster lid are：Protecting
Circumferentially arranged some protection cap hangers 14 on lid 10, it is circumferentially arranged on roaster lid 3 to there are some roaster lids to hang
Ear 15, the protection cap hanger 14 is with roaster lid hanger 15 in corresponding distribution two-by-two, the corresponding protection cap hanger of each pair
14 are fixed together with roaster lid hanger 15 by bolt 16 and the cooperation of nut 17, make protection cap 10 and roaster lid 3
It is affixed and fastens, above-mentioned protection cap and the connected mode of roaster lid is simple in construction, easy for installation；In the present embodiment, institute
The structure for stating protection cap is：Including the protection cap body with mounting groove surrounded by top plate 18 and side plate 19, the protection cap sheet
Body is set down in mounting groove notch, and the layer of resistance to material 20, the protection cap of said structure are cast with the mounting groove of protection cap body
Service life length；In the present embodiment, it is provided with to firmly grasp resistance to material on the top plate 18 in the mounting groove of protection cap body
The layer of resistance to material 20, so can preferably be fixed in the mounting groove of protection cap body, extend protection by the anchoring piece 21 of layer 20
The service life of lid；In the present embodiment, some channel-section steels 22 are also staggeredly distributed with the mounting groove of protection cap body, work as installation
In groove after the cast layer of resistance to material 20, channel-section steel 22 is embedded in the layer of resistance to material 20, so the layer of resistance to material 20 preferably can be fixed on into protection cap
In the mounting groove of body, the service life of protection cap is further extended；
The operation principle of the present invention is as follows：
During work, reversal valve 7 acts, and air hose 4 is connected with the first heat storage 9, while stores fume pipe 6 and second
Hot body 91 is connected, and now, air can enter the first burner 8 from the heat storage 9 of air hose 4 and first, be stored in air by first
During hot body 9, air can be heated by the first heat storage 9, will preheating high temperature air and coal gas mixed combustion in the first burner 8
And from during corresponding roaster lid fire output hole 12 and protection cap fire output hole 11 spray into ladle 23 downwards, preheating high temperature is empty
Gas can be after the second burner 81, the second heat storage 91 and reversal valve 7 from the row of fume pipe 6 with high-temperature flue gas caused by gas-fired
Go out, during high-temperature flue gas passes through the second heat storage 91, high-temperature flue gas can heat to the second heat storage 91 so that row
Going out the temperature of flue gas reduces, and after the second heat storage 91 is fully heated by high-temperature flue gas, by the counteragent of reversal valve 7, makes air
Pipe 4 is connected with the second heat storage 91, while fume pipe 6 is connected with the first heat storage 9, and now, air can be from air hose 4
And second heat storage 91 enter the second burner 81, air pass through the second heat storage 91 during, air can be by the second accumulation of heat
Body 91 heats, the second burner 81 will preheating high temperature air with coal gas mixed combustion and from corresponding roaster lid fire output hole 12
And during protection cap fire output hole 11 sprays into ladle 23 downwards, preheating high temperature air and high-temperature flue gas meeting caused by gas-fired
Discharged after the first burner 8, the first heat storage 9 and reversal valve 7 from fume pipe 6, pass through the mistake of the first heat storage 9 in high-temperature flue gas
Cheng Zhong, high-temperature flue gas can heat to the first heat storage 9 so that discharging the temperature of flue gas reduces, and repeats said process, i.e., real
The lasting baking to ladle 23 is showed；And during the first burner 8 or the second burner 81 carry out flame baking to ladle,
Because roaster lid 3 will not directly be heated under the protection of protection cap 10, so as to substantially reduce roaster lid bottom
Resistance to material substantially prolongs the service life of roaster because of the probability damaged by direct high-temperature baking.
