Abstract
A kind of scraper conveyor head housing side wall shaft extension part combination sealing structure, including labyrinth seal assembly, ring seal circle, packing_seal box, the labyrinth seal assembly includes sealing shroud, closure, sealing shroud is fixed on an axle by trip bolt, closure is fixed on head side guide by fastening bolt, when head axle is rotated, band movable sealing sleeve is rotated relative to closure；Ring seal circle is provided between head axle and closure；Packing_seal box is close to closure and is enclosed within an axle.A kind of scraper conveyor head housing side wall shaft extension part combination sealing structure of the utility model, it is ensured that the shaft extension position of head housing side wall head axle effectively seals, does not leak ash, not airborne dust.When solving prior art middle scraper conveyer and having malleation in its housing, head housing side wall shaft extension position leakiness ash, the defect of airborne dust.
Description
Technical field
The utility model is related to drag conveyor field, specifically a kind of scraper conveyor head housing side wall shaft extension position
Combined sealing structure.
Background technology
Drag conveyor in prior art, the shaft extension position of its head housing side wall head axle is generally only with single
Felt collar or the sealing of packing_seal box.When malleation is carried in conveyor casing body, when the material of such as conveying contains dust, which seals effect
Fruit is not good, and felt collar or packing box leakiness are grey, and head shell side plate head axle shaft extension position easily leaks generation airborne dust, pollute environment.
Content of the invention
When having malleation for overcoming prior art middle scraper conveyer in its housing, head housing side wall shaft extension position leakiness
Ash, the defect of airborne dust.The utility model provides a kind of scraper conveyor head housing side wall shaft extension part combination sealing structure, really
The shaft extension position for protecting head housing side wall head axle effectively seals, and does not leak ash, not airborne dust.
The technical scheme that the utility model is taken is：
A kind of scraper conveyor head housing side wall shaft extension part combination sealing structure, including labyrinth seal assembly, ring
Type sealing ring, packing_seal box, the labyrinth seal assembly include sealing shroud, closure, and sealing shroud is solid by trip bolt
Be scheduled on an axle, closure be fixed on head side guide by fastening bolt, head axle rotate when band movable sealing sleeve relative to
Closure is rotated；Ring seal circle is provided between head axle and closure；Packing_seal box is close to closure and is enclosed within an axle.
The sealing structure is arranged on the housing side wall shaft position of head axle in head assembly, by housing to being followed successively by outward fan
Palace formula black box, ring seal circle, packing_seal box.
Sealing gasket together with arranging between head side plate and head side guide binding face, with bolt assembly by head side plate, head
Portion's side guide connection is got rid of tight.
A kind of scraper conveyor head housing side wall shaft extension part combination sealing structure, advantage are：
1：The shaft extension position of head housing side wall head axle, after being sealed using the utility model sealing structure, in housing
When having malleation, dust will pass sequentially through labyrinth seal assembly, ring seal circle, packing_seal box triple seal, get to
Outside head shell, the probability of head shell leakage ash or airborne dust is greatly reduced.
2：Side plate is joined by head side plate sealing gasket together with the binding face increase of head side guide, blending bolt with side guide
Connect and tighten, further enhancing the effect of the sealing and anti-leakage ash of head shell.
Description of the drawings
Fig. 1 is black box scheme of installation of the present utility model.
Wherein：1- head side plates, 2- sealing gaskets, 3- head side guides, 4- head axles, 5- packing_seal boxes, 6- ring seals
Circle, 7- closures, 8- fastening bolts, 9- sealing shrouds, 10- great wheels.
Specific embodiment
As shown in figure 1, a kind of scraper conveyor head housing side wall shaft extension part combination sealing structure, close including labyrinth type
Sealing assembly, ring seal circle 6, packing_seal box 5, the labyrinth seal assembly include sealing shroud 9, closure 7, sealing shroud 9
It is fixed on an axle 4 by trip bolt, closure 7 is fixed on head side guide 3 by fastening bolt 8, so as to will be confused
Palace formula black box and ring seal circle 6 are fixed.When head axle 4 is rotated, band movable sealing sleeve 9 is rotated relative to closure 7, by rotation
Turn stagnation dust to leak.
Ring seal circle 6 is provided between head axle 4 and closure 7.
Packing_seal box 5 is close to closure 7 and is enclosed within an axle 4.
The sealing structure is arranged on the housing side wall shaft position of head axle 4 in head assembly, by housing to being followed successively by outward
Labyrinth seal assembly, ring seal circle 6, packing_seal box 5.
Sealing gasket 2 together with arranging between head side plate 1 and 3 binding face of head side guide.By head side plate 1 and head side pressure
The connection of plate 3 is changed to bolt assembly connection by conventional guiding briquetting connection, with bolt assembly by head side plate 1, head side pressure
The connection of plate 3 is got rid of tight.
