Description
Technical field
The utility model relates to a kind of dust-proof leakage sealed devices of screw conveyor, belong to screw conveyor technical field.
Background technique
Screw conveyor is a kind of using motor drive spiral revolution, elapses material to realize the machinery of conveying purpose.It
Energy level, inclination or vertical transport, being divided on transporting pattern has screw conveyor shaft and two kinds of Shaftless screw conveyor, there is axis
Screw conveyor is suitable for inviscid dry material and small particles material .(for example: cement, flyash, lime, grain etc.).In
In actual production, there is screw conveyor shaft for tilting transport dry material, due to the presence of mounting inclination angle degree, cause defeated
It send material to accumulate for a long time in the low order end of screw conveyor, exacerbates the deterioration of sealing ring use environment, while screw conveyor shaft
Since discontinuity deforms, the phenomenon for causing low order end ring wear unevenly to leak ash happens occasionally.It is existing after generation leakage ash
Replacement sealing ring is time-consuming and laborious, and is difficult to fundamentally to prevent identical phenomenon to occur again.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, it is close that the utility model provides a kind of dust-proof leakage of screw conveyor
Seal apparatus increases by the labyrinth seal structure added on the inside of hopper and on the outside of hopper and wears for compensation sealing circle
Clamping adjustment device, it is multi-pronged, substantially increase the dust seal of helical feed.
The utility model is achieved by the following technical solution: a kind of dust-proof leakage sealed device of screw conveyor,
It being characterized in that: including axis and bearing block, being equipped with labyrinth slotted disk on axis, bearing block is equipped with the maze trough of cooperation labyrinth slotted disk,
The maze trough insertion labyrinth slotted disk cooperation sealing, is filled with lubricating grease between labyrinth slotted disk and maze trough.
Further, sealing ring is additionally provided between the bearing block and axis.
Further, the sealing ring is lip-type packing, and sealing ring is around fitting axis.
Further, the packing pressing plate for being additionally provided with packing between the bearing block and axis and being assemblied on axis, packing
Pressing plate is equipped with hold-down bolt component, and hold-down bolt component adjusts packing pressing plate to the pressing force of packing.
Further, the packing pressing plate is equipped with wedge-shaped flanging, and wedge-shaped flanging is in packing pressing plate to the compression of packing
When packing is pressed against axle center by axis outer circle radially, so that sealing effect is restored and is promoted.
Further, the packing pressing plate and hold-down bolt component can be dismantled in outside.
The beneficial effects of the utility model are: by the labyrinth seal structure added on the inside of hopper and outside hopper
Side increases the clamping adjustment device for the abrasion of compensation sealing circle, multi-pronged, substantially increases the dust seal of helical feed
Property, the utility model sealing effect is good, and stability is high, and easy to adjust, maintenance is quick, and manufacturing cost is low.

Specific embodiment
A kind of dust-proof leakage sealed device of screw conveyor as shown in Figure 1 shares structure at three and is used to prevent outside dust
Leakage: include axis 1 and bearing block 2 at first, be equipped with labyrinth slotted disk 1-1 on axis 1, bearing block 2 is equipped with cooperation labyrinth slotted disk 1-1
Maze trough 2-1, the maze trough 2-1 insertion labyrinth slotted disk 1-1 cooperation sealing, between labyrinth slotted disk 1-1 and maze trough 2-1
Filled with lubricating grease.Labyrinth structure can prevent dust from leaking outside, and lubricating grease can not only lubricate, and can also play sealing and dustproof
Effect.
Dustproof construction is the sealing ring between the bearing block 2 and axis 1 between bearing block 2 and axis 1 at second
3, the sealing ring 3 is lip-type packing, and sealing ring 3 is around fitting axis 1.
Dustproof construction is the packing 4 between bearing block 2 and axis 1 and the packing pressing plate being assemblied on axis 1 at third
5.Packing pressing plate 5 is equipped with hold-down bolt component 6, and hold-down bolt component 6 adjusts packing pressing plate 5 to the pressing force of packing 4.Production
Packing 4 has abrasion caused by normal and improper reason in use, and sealing effect is caused to decline.Spiral shell is compressed by fastening at this time
Bolt assembly 6 increases the pressing force to packing 4, and the wedge-shaped flanging 5-1 on packing pressing plate 5 is by packing item 4 radially by axis outer circle
It is pressed against axle center, sealing effect is made to be restored and be promoted.Extremely by this sustainable 4 sealing effect of adjustment packing of packing pressing plate 5
Optimum state considerably increases the stability of screw conveyor.
Furthermore all firm bolts of installation of the utility model can be dismantled in outside, facilitate later maintenance, have sealing effect
Fruit is good, and stability is high, easy to adjust, and maintenance is quick, the advantages such as manufacturing cost is low.
