Description
Technical field
The utility model is related to material transfer equipment technical fields, and in particular to a kind of bucket type of tail portion built-in sealing device
Elevator.
Background technology
Bucket elevator abbreviation bucket elevator is for vertical or inclination conveying material mechanical conveying equipment, since it has
Have simple in structure, floor space is small, and improving material is steady, and hoisting depth is big, securely and reliably, the advantages that leakproofness is good, wide
It is general for smelting, digging up mine, in the industries such as harbour, building.
Bucket elevator can usually exist in use, at tailing axle and casing sealing emits grey phenomenon, some even meetings
There is the case where material leakage, while causing material waste, brings very big pollution to site environment, while dust easily enters
Bearing block accelerates the damage of bearing, these are all unfavorable for the stable operation of bucket elevator, in addition, also having using packing seal
What the mode of device sealed, but often have that packing seal effect is bad, and filler unbalance stress is fragile, filler is replaced when damaging
The problems such as inconvenient.Therefore, it develops a kind of tailing axle and casing sealing is functional, replacement is convenient, stable tail
The bucket elevator of portion's built-in sealing device is desirability.
Utility model content
The purpose of this utility model is to provide a kind of tailing axle and casing sealing are functional, replacement is convenient, operation
The bucket elevator of stable tail portion built-in sealing device.
The purpose of this utility model is achieved in that the utility model includes casing, drive sprocket, driven sprocket, plate
Chain, tailing axle and hopper, driven sprocket are mounted on the middle part of tailing axle, and the both ends of tailing axle are equipped with built-in sealing device, built-in sealing
Device includes gland and filler seat, and on tailing axle, one end of gland passes through bolt for gland and filler cover for seat
It is fixed on the side wall of casing, the other end is inserted into the inside of filler seat, the cavity formed between gland, filler seat and tailing axle
It is interior to be filled with packing, it is connected through a screw thread between gland and filler seat, and connect with packing on gland and filler seat
Inverted V-shaped is processed at tactile position, and the outside of gland and filler seat is provided with protective cover, and protective cover passes through screw thread and filler
Gland connects, and the depth L of protective cover is less than the sum of height of gland and filler seat H after packing compresses.
Further, the material of packing is felt.
Further, it is provided with gasket between gland and the side wall of casing.
Further, fluted, and gland, casing and tail are respectively processed on the contact surface of gland and casing
Airtight and watertight padding is filled in the cavity formed between axis.
Further, the hexagon step for facilitating rotation is machined on the outer wall of filler seat.
The connection between gland and filler seat is set as being threadedly coupled in the utility model, in installation and replacement side
Just while, for having compared the connection type using bolt and nut, the packing being placed in one can be by average axial direction
Pressure, because bolt and nut when connecting is carried out one by one by operating personnel, the degrees of tensions of bolt each in this way is different,
Will make packing unbalance stress, to influence the sealing performance of packing and the service life of packing, and in gland and
After being provided with protective cover outside filler seat, energy effective protection gland and filler seat are not damaged, and are more conducive to object
The isolation of material enhances sealing effect, and the utility model tailing axle and casing sealing are functional, and replacement is convenient, stable,
With significant economic value and social value.

Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation belongs to the scope of protection of the utility model based on any changes and modifications made by the utility model introduction.
Embodiment
As shown in Fig. 1~Fig. 2, the utility model includes casing 1, drive sprocket 2, driven sprocket 3, plate chain 4,5 and of tailing axle
Hopper 6, driven sprocket 3 are mounted on the middle part of tailing axle 5, and the both ends of tailing axle 5 are equipped with built-in sealing device, built-in sealing device packet
Gland 7 and filler seat 8 are included, gland 7 and filler seat 8 are sleeved on tailing axle 5, and one end of gland 7 passes through bolt
It is fixed on the side wall of casing 1, the other end is inserted into the inside of filler seat 8, is formed between gland 7, filler seat 8 and tailing axle 5
Cavity in be filled with packing 9, it is generally the case that the material of packing 9 can use felt, between gland 7 and filler seat 8
It is processed into inverted V-shaped, 7 He of gland in the position for being connected through a screw thread, and being contacted with packing 9 on gland 7 and filler seat 8
The outside of filler seat 8 is provided with protective cover 10, and protective cover 10 is connect by screw thread with gland 7, the depth L of protective cover 10
Less than the sum of the height that packing 9 is compacted rear gland 7 and filler seat 8 H.
The connection between gland 7 and filler seat 8 is set as being threadedly coupled in the utility model, in installation and replacement
While convenience, for having compared the connection type using bolt and nut, the packing 9 being placed in one can be by average axis
To pressure, because bolt and nut when connecting is carried out one by one by operating personnel, and the degrees of tensions of bolt each in this way is not
Together, will make 9 unbalance stress of packing, to influence packing 9 sealing performance and packing 9 service life, and in filler
After gland 7 and 8 outside of filler seat are provided with protective cover 10, energy effective protection gland 7 and filler seat 8 are not damaged, and
It is more conducive to the isolation of material, enhances sealing effect.In addition, the connection between gland 7 and filler seat 8 is set as screw thread
Connection, may occur mutual rotation in use, cause filler seat 8 to loosen, to make 9 decompression of packing, influence close
The effect of envelope, so the depth L of protective cover 10 is compacted the sum of the height of rear gland 7 and filler seat 8 H less than packing 9, this
The setting of sample, which allows for protective cover 10, to be pressed on filler seat 8 on gland 7, it is made not will produce axial displacement, drop
It is low that there is a situation where accidents.
In order to further prevent gap of the material in bucket elevator between gland 7 and casing 1 to leak, filler
It is provided with gasket 11 between gland 7 and the side wall of casing 1, is respectively processed on the contact surface of gland 7 and casing 1 fluted
12, and airtight and watertight padding 13 is filled in the cavity formed between gland 7, casing 1 and tailing axle 5, such setting is so that close
It is more preferable to seal effect.
During compressing, being compacted by packing 9, need constantly to rotate filler seat 8, in order to enable rotation is more convenient,
It is more laborsaving and effective, the hexagon step 14 for facilitating rotation is machined on the outer wall of filler seat 8, in this way can use spanner into
Row operation, improves the efficiency of work.
