Description
Technical field
This utility model relates to concrete recycle sandstone separation technology field, specifically a kind of sealing device for concrete washing girt-water separation machine.
Background technology
Concrete washing girt-water separation machine is the device that the sand of the inside and water carry out after being separated by the stone in the trucd mixer discarded concrete after cleaning further separation again, it drives helical axis to rotate by decelerator, the sand produced in preceding working procedure and sewage are stirred, sand is hoisted promotion by the helical blade on helical axis, and the sand export through top is discharged；In the course of conveying of sand, sand is carried out dehydration by helical blade simultaneously, and the unnecessary sewage osculum through the frame back side overflows, and then passes through outside guiding gutter and flows in sedimentation tank.
The sealing device of spiral conveying mechanism bottom is critically important parts, because helical axis works in the environment of sand and sewage, if the sealing of its bottom is bad, its bearing and spindle nose are easy to be damaged by mud abrasion, corrosion in water.Generally, shaft end seal adopts layer 2-3 sealing device, but practical effect is bad, and bearing and helical axis spindle nose are corroded through being easily used to after a while, wear and tear and lost efficacy.
Summary of the invention
To be solved in the utility model it has a problem in that the deficiency overcoming above-mentioned prior art, it is provided that a kind of simple in construction, the respond well sealing device for concrete washing girt-water separation machine.
This utility model realizes with following technical scheme: a kind of sealing device for concrete washing girt-water separation machine, including frame and the helical axis being arranged in frame, the side of described frame is provided with the bearing block that the spindle nose with helical axis is connected, described bearing block is provided with end cap, a pushing out ring it is provided with between described bearing block and frame, being respectively equipped with external seal pad and interior sealing gasket between both sides and bearing block and the frame of described pushing out ring, described pushing out ring is provided with the spout hole being disposed radially；It is provided with backbone sealing ring between described frame and spindle nose；The opposite side of described frame is provided with the cover plate being enclosed within spindle nose, is provided with felt circle between described cover plate and spindle nose, and described external seal pad, interior sealing gasket, backbone sealing ring and felt circle are all in close contact with spindle nose.
It is further: the material of described external seal pad and interior sealing gasket is nitrile rubber.
Described external seal pad, interior sealing gasket, backbone sealing ring and felt circle are annular.
Together with described bearing block, a pushing out ring are bolted on frame, described cover plate is fixed by screws in frame.
This utility model has the advantage that this utility model device adopts the structure of four-layer seal, and pushing out ring is provided with spout hole, assuming inboard three-layer sealed damage, sewage by discharging here, can also thus avoid sewage to enter bearing and make bearing generation heavy wear.This sealing device working life is obviously prolonged, economical and effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, spindle nose, 2, bearing block, 3, external seal pad, 4, interior sealing gasket, 5, a pushing out ring, 6, frame, 7, backbone sealing ring, 8, cover plate, 9, felt circle, 10, helical axis, 11, spout hole, 12, end cap.
Detailed description of the invention
A kind of sealing device for concrete washing girt-water separation machine as shown in Figure 1, including frame 6 and the helical axis 10 being arranged in frame 6, the side of described frame 6 is provided with the bearing block 2 that the spindle nose 1 with helical axis 10 is connected, described bearing block 2 is provided with end cap 12, a pushing out ring 5 it is provided with between the 6 of described bearing block 2 and frame, being respectively equipped with external seal pad 3 and interior sealing gasket 4 between both sides and bearing block 2 and the frame 6 of described pushing out ring 5, described pushing out ring 5 is provided with the spout hole 11 being disposed radially；It is provided with backbone sealing ring 7 between described frame 6 and spindle nose 1；The opposite side of described frame 6 is provided with the cover plate 8 being enclosed within spindle nose 1, is provided with felt circle 9 between described cover plate 8 and spindle nose 1, and described external seal pad 3, interior sealing gasket 4, backbone sealing ring 7 and felt circle 9 are all in close contact with spindle nose.nullOne end of helical axis of the present utility model is movably fixed in frame，The side of frame is provided with the bearing block being connected with spindle nose，Owing to spindle nose all has contact site with frame and bearing block，In order to ensure the sealing at spindle nose place，In the contact position of spindle nose with bearing block with frame, sealing device is set，Wherein，A pushing out ring it is provided with between bearing block and frame，Support ring set on spindle nose，Pushing out ring the position that contacts with bearing block and frame respectively, both sides be provided with external seal pad and interior sealing gasket，The internal ring of inside and outside sealing gasket and spindle nose close contact，Additionally it is provided with the backbone sealing ring being enclosed within spindle nose between frame and spindle nose，The opposite side of frame is provided with the cover plate being enclosed within spindle nose，The contact position of cover plate and spindle nose is provided with felt circle，Backbone sealing ring is same with felt circle to be in close contact with spindle nose，Four road sealing devices arranged can effectively ensure that the sealing effectiveness at spindle nose place，In addition，A pushing out ring is additionally provided with spout hole radially，When felt circle、When backbone sealing ring and interior sealing gasket all lost efficacy，What flow out just can discharge in spout hole，Sewage is avoided to enter the bearing of spindle nose and bearing block place and make bearing generation heavy wear，Improve the service life of spindle nose and bearing.
A kind of sealing device for concrete washing girt-water separation machine as shown in Figure 1, the material of described external seal pad 3 and interior sealing gasket 4 is nitrile rubber.
A kind of sealing device for concrete washing girt-water separation machine as shown in Figure 1, described external seal pad 3, interior sealing gasket 4, backbone sealing ring 7 and felt circle 9 are annular.Each seal member of the present utility model all adopts annular, and is enclosed within spindle nose, it is ensured that spindle nose all can effectively seal for a week at sealing station, strengthens the sealing effectiveness at spindle nose position.
A kind of sealing device for concrete washing girt-water separation machine as shown in Figure 1, together with described bearing block 2, a pushing out ring 5 are bolted on frame 6, described cover plate 8 is fixed by screws in frame 6.Bearing block of the present utility model, prop up pushing out ring and cover plate is all fixed together with frame, it is prevented that bearing block, a pushing out ring, generation relative motion between cover plate and frame, thus preventing from, because the change in location of the sealing device at each position causes the reduction of sealing effectiveness, improve the sealing effectiveness of whole device.
