Abstract
The invention discloses a positive pressure dedusting structure for a cone crusher. The positive pressure dedusting structure comprises an upper rack, a slide ring cover, a lower rack and a horizontal bearing installation seat. The lower rack is provided with a horizontal bearing installation hole. The horizontal bearing installation seat is located in the horizontal bearing installation hole. The horizontal bearing installation hole is communicated with an inner cavity of the slide ring cover. A horizontal bearing is arranged in the horizontal bearing installation seat. A gas inlet passage is formed between the horizontal bearing installation seat and the horizontal bearing installation hole. The horizontal bearing installation seat is provided with a gas inlet hole. One end of the gas inlet passage is communicated with the inner cavity of the slide ring cover. The other end of the gas inlet passage is communicated with the gas inlet. Compared with the prior art, according to a gas inlet structure of the positive pressure dedusting structure, the large structural size of the horizontal bearing seat is used, so that the through diameter of the gas inlet for positive pressure dedusting is enlarged, and accordingly the gas inflow is increased, and the dedusting effect of a positive pressure dedusting system is ensured. Dust is effectively prevented from entering the machine, so that the service life of the cone crusher is prolonged, and good economic benefits are achieved.
Description
Technical field
The present invention relates to the single-cylinder hydraulic circular cone belonged in mining machinery and manufacture field, particularly relate to a kind of gyratory crusher malleation dedusting structure.
Background technology
At present, single-cylinder hydraulic circular cone breaks high with its crushing efficiency, that grain type is good advantage and makes it obtain application widely at field of cracking machine.Single-cylinder hydraulic circular cone is broken is power source with motor, drives circular cone to break horizontal rotational shaft, then drives eccentric bushing by trunnion axis, make mantle portion do swing campaign, make the extruding that material in chamber is circulated, thus obtain the object of broken building stones by V-belt.In the course of the work, owing to there being a lot of dust in environment, easy intrusion equipment inner chamber, causes fluid to be subject to dust pollution to Single-Cylinder Hydraulic Cone Crusher, thus the movable part aggravating to be lubricated weares and teares, and shortens service life of a machine.Malleation air intake structure main at present, mainly from lower bearing bracket air inlet, enters slip ring cover inner chamber by pipeline elongated on slip ring cover, is limited to slip ring cover physical dimension, and it is very little that admission line latus rectum does, and affects gas and enter inner chamber, thus affect malleation dust removing effects.
Summary of the invention
Object of the present invention is just to provide one to solve the problem, simple and reliable, and latus rectum is comparatively large, the gyratory crusher malleation dedusting structure that air inflow is larger.
To achieve these goals, the technical solution used in the present invention is: a kind of gyratory crusher malleation dedusting structure, comprise upper spider, slip ring cover, lower bearing bracket and horizontal bearing mount pad, described lower bearing bracket offers horizontal bearing installing hole, described horizontal bearing mount pad is positioned at horizontal bearing installing hole, described horizontal bearing installing hole and slip ring cover inner space, horizontal bearing is provided with in described horizontal bearing mount pad, inlet channel is offered between described horizontal bearing mount pad and horizontal bearing installing hole, described horizontal bearing mount pad offers air admission hole, described inlet channel one end and slip ring cover inner space, its other end and air admission hole.
As preferably, be provided with the O RunddichtringO avoiding inlet channel to leak gas between horizontal bearing mount pad and horizontal bearing installing hole, described sealing ring is positioned at the outside opening place of horizontal bearing installing hole.
As preferably, the outside opening place of described horizontal bearing mount pad and horizontal bearing installing hole fits tightly, and is fixedly connected with by the frame of fastening bolt with horizontal bearing installing hole place.
As preferably, the aperture of described air admission hole is 20-40mm.
As preferably, the inlet channel width between described horizontal bearing mount pad and horizontal bearing installing hole is 30-60mm.
Compared with prior art, the invention has the advantages that: the physical dimension that air intake structure of the present invention utilizes trunnion axis bearing place larger, expand the air admission hole latus rectum of malleation dedusting, thus improve air inflow, ensure that the dust removing effects of positive pressure dust cleaning system, effectively prevent dust and enter machine intimate, extend circular cone and break service life, obtain good economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, upper spider; 2, lower bearing bracket; 3, slip ring cover; 4, air admission hole; 5, horizontal bearing mount pad; 6, inlet channel.
Detailed description of the invention
The invention will be further described below.
Embodiment 1: see Fig. 1, a kind of gyratory crusher malleation dedusting structure, comprise upper spider 1, slip ring cover 3, lower bearing bracket 2 and horizontal bearing mount pad 5, described upper spider 1 is fixedly connected with lower bearing bracket 2, described lower bearing bracket 2 offers horizontal bearing installing hole, described horizontal bearing mount pad 5 is positioned at horizontal bearing installing hole, described horizontal bearing installing hole and slip ring cover 3 inner space, horizontal bearing is provided with in described horizontal bearing mount pad 5, inlet channel 6 is offered between described horizontal bearing mount pad 5 and horizontal bearing installing hole, described horizontal bearing mount pad 5 offers air admission hole 4, inlet channel 6 width is 20-40mm, the aperture of described air admission hole 4 is 30-60mm, now ventilatory effect is better, inner chamber forms positive regulation, dust removing effects is best.Described inlet channel 6 one end and slip ring cover 3 inner space, its other end and air admission hole 4.The O RunddichtringO avoiding inlet channel 6 to leak gas is provided with between horizontal bearing mount pad 5 and horizontal bearing installing hole, described sealing ring is positioned at the outside opening place of horizontal bearing installing hole, described horizontal bearing mount pad 5 fits tightly with the outside opening place of horizontal bearing installing hole, and be fixedly connected with by the frame of fastening bolt with horizontal bearing installing hole place, make inlet channel 6 form Semi-seal structure by said structure, effectively prevent ambient atmos and enter inlet channel 6.Air inlet pipe can only be adopted from air admission hole 4 air inlet.
During operation, inlet channel 6 is entered by the air admission hole 4 of trunnion axis installation site on lower bearing bracket 2, enters lower bearing bracket 2 inner chamber by trunnion axis bearing block circumference, and enters slip ring cover 3 inner chamber by slip ring cover 3 bottom, thus form malleation at inner chamber.Thus expand the air inlet latus rectum of malleation dedusting, improve air inflow, ensure that the dust removing effects of positive pressure dust cleaning system, effectively prevent dust and enter machine intimate, extend circular cone and break service life, obtain good economic benefit.
Above exhaustive presentation is carried out to a kind of gyratory crusher malleation dedusting structure provided by the present invention, apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, to change of the present invention and improve will be possible, and design and the scope of accessory claim defined can not be exceeded, in sum, this description should not be construed as limitation of the present invention.
