Specific embodiment
As shown in Figs. 1-5, a kind of anaerobic continuous tunnel furnace of the present invention mainly passes sequentially through conveyer belt including horizontal direction
Pan feeding section 210, pan feeding breeze way 220, bringing-up section 100, discharging breeze way 320 and the discharging section 310 of connection.Between each section respectively
One airtight gate is set for closing, the first airtight gate 211 wherein between pan feeding section 210 and pan feeding breeze way 220 is set, is entered
Second airtight gate 221 between material breeze way 220 and bringing-up section 100 is set, is set between bringing-up section 100 and discharging breeze way 320
Put setting third airtight gate 311 between the 4th airtight gate 321 and discharging breeze way 320 and discharging section 310.Described
Each airtight gate can be the pneumatic door for having 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 of side and discharging breeze way 320, when oxygen is scurried into the variation of oxygen amount will not fluctuate too big.In bringing-up section
The pan feeding breeze way 220 for being arranged side by side and extending vertically upwards and discharging breeze way 320 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, hoisting mechanism 120 moves baking part 400 with 130 top of descending mechanism by translation mechanism；120 top of hoisting mechanism
It is best baking position.Hoisting mechanism 120 and descending mechanism 130 are respectively equipped with four groups of wheel belt mechanisms, between four groups of wheel belt mechanisms
Vertical parallel setting, and be synchronized with the movement.Four ends of four groups of wheel belt mechanism difference support baking parts 400, make baking part 400 can
To keep horizontality vertical displacement movement.Due to the continuous tunnel furnace of different previous horizontal direction extensions, arrive hang down from horizontal direction
Nogata to movement conversion easily loosen, therefore smoothly converting motion direction is particularly important for the part not toasted.
100 top of bringing-up section is additionally provided with the vane device dried downwards higher than the position of hoisting mechanism 120.It is described
Vane device including a driving motor 110 and vane, is passed through after the socket axle sleeve 112 of shaft 111 of the driving motor 110 and is added
100 upper wall surface of hot arc extends to 120 top of hoisting mechanism, and vane drives rotation by shaft 111.112 outer wall of axle sleeve leads to
Hmp grease and 100 corresponding through-hole air tight contact of bringing-up section are crossed, and at both ends radially outward from the gas made by soft silica gel
Close plate 113 is fitted in 100 both 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 air outlet 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 being penetrated outside bringing-up section 100 nearby or immediately below vane, and ends in 120 top end of hoisting mechanism；Institute
The air outlet pipe 102 stated is extended to after being penetrated 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 air outlet pipe 102.
The operation principle of the present invention is as follows, and baking part 400 is entered the pan feeding section 210 of atmospheric environment by conveyer belt first, so
First airtight gate 211 unlatching afterwards makes baking part 400 be entered in pan feeding breeze way 220 by pan feeding section 210, at this time the second gas
Close gate 221 remains off.Baking part 400 closes the first airtight gate 211 after reaching pan feeding breeze way 220, passes through row
Oxygen pipeline discharges into the oxygen in material breeze way 220, makes to be adapted in 220 oxygen amount of pan feeding breeze way and bringing-up section 100.Then it opens
Second airtight gate 221 makes baking part 400 enter 120 lower section of hoisting mechanism from pan feeding breeze way 220, turns off the second gas
Close gate 221.Hoisting mechanism 120 steadily drives baking 400 vertical ascent of part by four groups of wheel belt mechanisms to end, and in air inlet
Pipe 101, air outlet pipe 102 under the cooperation of vane with keeping oxygen-free environment to be toasted.It is moved after baking by translation mechanism
Baking part 400 is steadily driven to be displaced downwardly to decline machine to 130 end of descending mechanism, and by four groups of wheel belt mechanisms of descending mechanism 130
130 lower part of structure.The closing of the 4th airtight gate 321 and third airtight gate 311 is kept, passes through the deoxygenation for the breeze way 320 that discharges
Pipeline discharges its oxygen, and the oxygen amount and bringing-up section 100 for making discharging breeze way 320 are adapted.It opens the 4th airtight gate 321 and enables and dry
Roasting part 400 is entered from 130 lower part of descending mechanism in discharging breeze way 320, closes the 4th airtight gate 321.Finally open
The discharging section 310 that baking part 400 is delivered under atmospheric environment is completed anaerobic baking process by three airtight gates 311.Multiple bakings
Part 400 can be cycling in and out bringing-up section 100 under above-mentioned method of work, without causing wave to the oxygen amount in bringing-up section 100
It is dynamic, remain good cured effect.
For those skilled in the art, technical solution that can be as described above and design are made other each
The corresponding change of kind and deformation, and all these changes and deformation should all belong to the protection model of the claims in the present invention
Within enclosing.
