Sternly, material is easy to leak out from gap position, is damaged to environment, therefore screw conveyor sealing performance quality is equipment success
Whether key.
Screw conveyor belongs to general conveying machinery equipment, using bearings at both ends supporting structure, if fed distance is too far, and spiral shell
Spin axis amount of deflection is very big, and bending phenomenon occurs for meeting during conveying material, and blade easily occurs during use and is worn with shell
Generally make blade and gap at shell, axis and end seat sealing slightly larger when wearing, therefore designing at axis and end seat sealing, to ensure
Equipment runs well.But because axis and gap at end seat sealing are slightly larger, sealing effect is very poor, common encapsulating method is
Using packing_seal, sealing effect is also possible that the abrasion due to axle journal and packing, sealing after operation a period of time when starting running
Effect is worse and worse.
Therefore it needs, according to material characteristic, fed distance, to rationally design screw conveyor helical axis and tie with end seat sealing
Structure can just make screw conveyor normal operation.

Machine helical axis and end seat sealing structure, to meet the requirement of screw conveyor normal operation.
To solve the above problems, the technical solution of the utility model is：
A kind of screw conveyor helical axis and end seat sealing structure, including it is socketed in the end cap outside helical axis and sealing
Component, the seal assembly include：Sealing is fixed on the axle sleeve outside helical axis, packing, disk with axle sleeve rotatory sealing cooperation
Root box；Wherein, packing combines for multi-turn packing, and is sleeved on packing box inner cavity according to this, and packing box one end is fixed with end cap seal
Connection, the packing box other end coordinate with adjustment seat plugged and fixed, and adjustment seat constitutes extrusion fit with packing；End cap and axle sleeve it
Between constitute rotatory sealing cooperation.
Said program further comprises：
Outside framework oil seal is also equipped in the packing box, and outside framework oil seal is implemented to seal together with packing to axle sleeve.
Partition board is additionally provided in the packing box, partition board is between outside framework oil seal and packing.
It is equipped with one or multi-channel sealing ring between the axle sleeve and helical axis to seal, and passes through pin between axle sleeve and helical axis
Axis is fixed.
The adjustment seat is axially connect with packing box by adjusting bolt, and packing box is coordinated with end cap by briquetting and bolt
It is fixedly connected, and sealing element is set in packing box and end cap involutory surface.
The packing uses six circles or more.
Compared with prior art, the utility model has the beneficial effects that：
1, helical axis and end seat sealing effect are good, meet the requirement of screw conveyor long range normal operation；2, spiral axle journal
Add axle sleeve, protects spiral axle journal not frayed；3, helical axis and the sealing element of end seat are adjusted, are replaced conveniently；4, it can be applied to
Other rotary shafts and end seat field of sealing technology.
Description of the drawings
Fig. 1 is the screw conveyor helical axis and end seat sealed structural representation of the utility model.
Reference numeral：1- end caps, 2- outside framework oil seals, 3- partition boards, 4- packing boxs, 5- packings, 6- adjustment seats, 7- axle sleeves, 8-

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, a kind of helical axis and end seat sealing structure, including end cap 1, outside framework oil seal 2, partition board 3, packing box 4, disk
Root 5, adjustment seat 6, axle sleeve 7, helical axis 8, O-ring 9, O-ring 10.
Packing box 4 and adjustment seat 6 are also equipped in end seat, helical axis 8 passes through packing box 4, axle sleeve 7 is housed on helical axis 8；Spiral shell
Spin axis 8 is divided into static seal and dynamic sealing with end seat sealing：Axle sleeve 7 is rotated together with helical axis 8, is static seal；End seat does not rotate,
It is dynamic sealing between axle sleeve 7；Packing 5 is housed, packing 5 is sleeved on axle sleeve 7 in packing box 4；Adjustment seat 6 is for compressing packing
5。
Further, it is also equipped with outside framework oil seal 2 in packing box 4；End seat and the dynamic sealing of axle sleeve 7 are using O-ring 10, bone
The combination sealing of frame oil sealing 2 and packing 5；It is sealed using O-ring 10 between end cap 1 and axle sleeve 7, bone is used between packing box 4 and axle sleeve 7
Frame oil sealing 2 and packing 5 seal, and outside framework oil seal 2 is located at 5 front of packing；The static seal of the axle sleeve 7 and helical axis 8 is to adopt
With O-ring 9.
