As shown in Fig. 2, be arranged with the second gasket 6 outside horizontal loops 41, the second gasket 6 along away from kiln hood 1 and parallel to
The direction extension of kiln body 2.2 outer wall of kiln body is welded with second baffle 22, and second baffle 22 is located at first baffle 21 away from kiln hood 1
Side, second baffle 22 are contradicted with the second gasket 6.By the first gasket 5, the second gasket 6 and second baffle 22 to kiln
First 1 is sealed with the junction of kiln body 2, forms the secondary seal of dynamic and static ring.
As shown in Fig. 2, the one end of second baffle 22 away from kiln body 2 is welded with annular slab 221, make annular slab 221 and second
6 face of gasket contacts.Annular slab 221 can increase the contact surface with the second gasket 6, improve sealing effect.
As shown in Fig. 2, Circle-Array shows some air intake branches 8 in horizontal loops 41, air intake branch 8 is located at kiln hood 1 and first
Between baffle 21.Kiln hood 1 is equipped with air flue 7 close to a side lower part of kiln body 2, and air flue 7 is located in horizontal loops 41, it is preferred that this reality
Apply stayed in example between kiln hood 1 and kiln body 2 air flue 7 gap be 3 centimetres to 5 centimetres.Gas is passed through in air intake branch 8, is made
Positive pressure is formed in the cavity in the left side of first baffle 21, gas enters kiln hood 1 through air flue 7, air flue 7 carried out by gas close three times
Envelope, it is possible to reduce material flies out from air flue 7, so as to improve sealing effect.In addition, from the gas that air flue 7 is blown out to the thing that raises up
Material has the resistance of a transverse direction, under the effect of gravity, it is possible to reduce material flies out from exhaust outlet 11.
As shown in Fig. 2, kiln hood 1 is stretched into one end that kiln body 2 is located at kiln hood 1, and gap is left in the side opposite with kiln hood 1,
In the present embodiment, the length that kiln body 2 is stretched into kiln hood 1 is 5cm.Kiln hood 1 is stretched into one end of kiln body 2, can increase material extremely
Stroke between 2 junction of kiln hood 1 and kiln body, can efficiently reduce leakage of the material from kiln hood 1 Yu 2 junction of kiln body.
As shown in Fig. 2, the position that air intake branch 8 is located at the first air inlet 9 is provided with infrared heater 10.Infrared heater
10 can heat the gas for entering kiln hood 1, reduce in kiln hood 1 gas with material is cold and hot cross when condense can
Energy property, so as to improve dry mass.
As shown in Figure 1, being provided with ring-shaped guide rail 23 on the outside of 2 both ends of kiln body, roller 101 is provided with the ground, is rolled
Wheel 101 coordinates with ring-shaped guide rail 23 allows kiln body 2 to occur freely to rotate.Sliding tooth 24 is also arranged with the outside of kiln body 2,
The driving motor 102 coordinated with sliding tooth 24 is provided with the ground, by driving motor 102 and the cooperation of sliding tooth 24 to drive
Kiln body 2 rotates.
As shown in Figure 1, being provided with feed inlet 12 in side of the kiln hood 1 away from kiln tail 3, the top of kiln hood 1 is provided with row
Air port 11.Side of the kiln tail 3 away from kiln hood 1 is provided with the second air inlet 31, the downside of kiln tail 3 is provided with discharge port 32.
One end that wherein kiln body 2 is connected with kiln hood 1 is higher than the one end being connected with kiln tail 3.
Specific implementation process:Driving motor 102 drives sliding tooth 24 to rotate, and sliding tooth 24, which rotates, drives kiln body 2 to rotate;Together
When hot wind is blown into kiln body 2 from the second air inlet 31, and discharged from exhaust outlet 11;Hot wind is being blown into kiln body 2
Meanwhile hot wind is also inputted by air intake branch 8, this part hot wind is cut transversely into exhaust outlet 11 and kiln body 2 from air flue 7.
Then material to be dried is poured into kiln body 2 from feed inlet 12, is constantly rotated by kiln body 2 and drive material constantly by band
The process fallen again to eminence, material can sufficiently be contacted with hot wind, so as to fulfill quick-drying purpose, and due to
Kiln body 2 is obliquely installed, thus with kiln body 2 rotate stirring during can also be slowly moved to 3 direction of kiln tail, when
Material is discharged when reaching the discharge port 32 of kiln tail 3, and it is continuous drying that such process can realize that material carries out, and improves dry effect
Rate.And during kiln body 2 rotates(Its sealing structure is because the both ends of kiln body have and structure is identical, therefore herein with kiln
Sealing structure between body 2 and kiln hood 1 illustrates, and kiln tail 3 and the seal operation principle of kiln body 2 are same, do not exist herein
Repeat), the rotation of kiln body 2 drives first baffle 21 and second baffle 22 to rotate together, and the first gasket 5 is due to by pressure strip 51
Effect and being against on the outer wall of kiln body 2 at every moment, the gap between ring-type fixing plate 4 and kiln body 1 is sealed;Together
When 221 and second gasket 6 of annular slab between be also constantly in the state of contact, and contact surface is face contact, its contact surface
Greatly, and then sealing performance is higher.Exterior air has to pass through the sealing surface between 221 and second gasket 6 of annular slab, then passes through
The sealing surface between the first gasket 5 and kiln body 2 is crossed, recrosses the gap of first baffle 21 and horizontal loops 41, Ran Houcong afterwards
Air flue 7 could contact after exporting with the material in kiln body 2, and the path during this is more, and be in conflict
State, thus leakproofness is preferable.Gas is inputted additionally, due to air intake branch 8 always and is exported from air flue 7, thus makes the first sealing
Conflict power bigger between pad 5 and kiln body 2, increases sealing effect, while the granular material in kiln body 2 is not easily accessible sealing
The service life of sealing structure is influenced in structure.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
