Specific embodiment
As shown in Figs. 1-5, a kind of anaerobic continuous tunnel furnace described in the utility model is mainly passed sequentially through including horizontal direction defeated
Send pan feeding section 210, pan feeding breeze way 220, bringing-up section 100, discharging breeze way 320 and the discharging section 310 of band connection.Each section it
Between an airtight gate is respectively set for closing, the first airtight gate is wherein set between pan feeding section 210 and pan feeding breeze way 220
211, the second airtight gate 221, bringing-up section 100 and discharging breeze way 320 are set between pan feeding breeze way 220 and bringing-up section 100
Between be arranged the 4th airtight gate 321, and discharging breeze way 320 and discharging section 310 between be arranged third airtight gate 311.
Each airtight gate can be the pneumatic door with tight function.
Wherein the height of bringing-up section 100 is higher than other each section, ensure that the space in bringing-up section 100 is significantly larger than left and right two
The pan feeding breeze way 220 and discharging breeze way 320 of side, when oxygen is scurried into, the variation of oxygen amount will not be fluctuated too big.In bringing-up section
The pan feeding breeze way 220 and discharging breeze way 320 that are arranged side by side and extend vertically upwards are equipped in 100.The hoisting mechanism
By conveying band connection pan feeding breeze way 220,130 lower part of descending mechanism is slow by conveying band connection discharging for 120 lower parts
Section 320 is rushed, passes through the mobile baking part 400 of translation mechanism at the top of hoisting mechanism 120 and descending mechanism 130；Hoisting mechanism
120 tops are best baking positions.Hoisting mechanism 120 and descending mechanism 130 are respectively equipped with four groups of wheel belt mechanisms, four groups of wheel belt
Vertical parallel setting between mechanism, and move synchronously.Four ends of baking part 400 described in four groups of wheel belt mechanism difference supports
Portion allows the baking part 400 to keep horizontality vertical displacement movement.Extend due to different previous horizontal directions
Continuous tunnel furnace, the movement conversion for arriving vertical direction from horizontal direction is easy to loosen for the part not toasted, therefore smoothly turns
It is particularly important to change the direction of motion.
The position that 100 top of bringing-up section is higher than hoisting mechanism 120 is additionally provided with the vane device dried downwards.It is described
Vane device, including a driving motor 110 and vane, the shaft 111 of the driving motor 110 passed through after being socketed axle sleeve 112 plus
100 upper wall surface of hot arc extends to 120 top of hoisting mechanism, and vane is driven by shaft 111 to be rotated.112 outer wall of axle sleeve is logical
Hmp grease through-hole air tight contact corresponding with bringing-up section 100 is crossed, and extends radially outward the gas being made by soft silica gel at both ends
Close plate 113 is fitted in 100 two sides of bringing-up section.Same principle, any rotating mechanism for passing through bringing-up section 100 or other airtight spaces
The tight mechanism can be used to be tightly connected.
Perforative air inlet pipe 101 and escape pipe 102 are also set up in 100 upper wall surface of bringing-up section.The air inlet pipe 101 from
Vane is extended to after penetrating outside bringing-up section 100 nearby or immediately below vane, and ends in 120 top end of hoisting mechanism；Institute
The escape pipe 102 stated is extended to after penetrating outside bringing-up section 100 below 120 top of hoisting mechanism.For diluting the nitrogen of oxygen amount
It enters inside bringing-up section 100, is moved downward by vane driving, it is ensured that the office near 120 top of hoisting mechanism from air inlet pipe 101
Portion space oxygen content reaches minimum, is then discharged again by escape pipe 102.
The working principle of the utility model is as follows, and the baking part 400 enters entering for atmospheric environment by conveyer belt first
Expect section 210, then the first airtight gate 211 unlatching makes the baking part 400 enter pan feeding breeze way by pan feeding section 210
In 220, the second airtight gate 221 is remained off at this time.The baking part 400 is closed after reaching pan feeding breeze way 220
First airtight gate 211 discharges into the oxygen in material breeze way 220 by deoxygenation pipeline, makes 220 oxygen amount of pan feeding breeze way and add
Adaptation in hot arc 100.Then it opens the second airtight gate 221 and enters the baking part 400 from pan feeding breeze way 220 and mention
120 lower section of mechanism is risen, the second airtight gate 221 is turned off.Hoisting mechanism 120 by four groups of wheel belt mechanisms steadily drives described in
400 vertical ascent of part is toasted to end, and keep under the cooperation of air inlet pipe 101, escape pipe 102 and vane oxygen-free environment into
Row baking.130 end of descending mechanism is moved to by translation mechanism after baking, and by four groups of wheel belt of descending mechanism 130
Mechanism steadily drives the baking part 400 to be displaced downwardly to 130 lower part of descending mechanism.Keep the 4th airtight gate 321 and third gas
The closing of close gate 311, by discharge breeze way 320 deoxygenation pipeline its oxygen is discharged, make discharge breeze way 320 oxygen amount with
Bringing-up section 100 is adapted.Opening the 4th airtight gate 321 enables the baking part 400 enter from 130 lower part of descending mechanism
It discharges in breeze way 320, closes the 4th airtight gate 321.Third airtight gate 311 is finally opened by the baking part 400
The discharging section 310 being delivered under atmospheric environment completes anaerobic baking process.Multiple baking parts 400 can be in above-mentioned work
It is cycling in and out bringing-up section 100 under method, without causing to fluctuate to the oxygen amount in bringing-up section 100, remains good baking
Effect.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
The corresponding change of kind and deformation, and all these changes and deformation all should belong to the guarantor of the utility model claims
Within the scope of shield.
