Description

Crushing tooth applied to single-toothed-roller crusher

Technical Field

The utility model belongs to the technical field of crushing equipment, a use broken tooth on single-tooth roller crusher is related to.

Background

In the sintering production process of iron and steel production enterprises, blocky sinter sintered by a sintering machine needs to enter a single-roll crusher for crushing, and then the next process is carried out.

At present, the crushing teeth of single-tooth roller crushers used in the sintering process of each iron and steel industry and the conventional single-tooth roller crushers produced by each producer have a structure generally shown in fig. 1. The crushing tooth of the traditional single-roll crusher consists of a tooth arm 601 and a tooth head 602, wherein the base material of the tooth arm 601 is common structural steel, and the material of the tooth head 602 is wear-resistant alloy steel. The cross-sectional dimension of the arm 601 near the tooth roller (hereinafter referred to as tooth root) is large, the cross-sectional dimension of the arm 601 far from the tooth roller (hereinafter referred to as tooth tip) is small, the arm 601 is welded and fixed on the tooth roller shaft, a wear-resistant layer with the thickness of about 10mm is overlaid on the outer surface of the arm 601, and the tooth head 602 is welded on the arm 601. The crushing teeth of the single-toothed roller crusher with the structure have the following problems: the tooth head 602 is welded on the tooth arm 601, welding is needed, the welding amount is large, and fracture accidents are easy to happen; the sectional area of the connecting part of the tooth arm 601 and the tooth head 602 is small, and the hardfacing layer is thin, so that the wear is easy to occur, and the tooth roller device is often replaced due to serious wear at the connecting part.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above shortcoming of prior art, the utility model provides an use broken tooth on single-tooth roller crusher has and makes simply, and intensity is high, characteristics such as wear resistance is good for make simpler, more wear-resisting, prolonged single-roller crusher's life, in order to reach extension sintering machine continuous production time, reduce the maintenance number of times, improve sintering machine operation rate.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an use broken tooth on single fluted roller breaker, includes fluted roller and installs the base member on the fluted roller, has the hardfacing layer at fluted roller and base member surface parcel.

Furthermore, the base body is in a solid cuboid shape, the end, contacting the base body with the gear roller, of the base body is a tooth root, the end, far away from the gear roller, of the base body is a tooth tip, the wear-resistant surfacing layers are gradually thickened along the direction from the tooth root of the broken tooth to the tooth tip, the thickness of surfacing layers on the tooth root and the gear roller is 8-12mm, and the thickness of surfacing layers at the tooth tip is 20-30 mm.

Furthermore, the toothed roller and the base body are integrated by adopting an integral structure.

Furthermore, a shaft hole is formed in the middle of the gear roller, a gear roller shaft penetrates through the shaft hole, water is introduced into the shaft hole and used for cooling the gear roller shaft, the shaft is supported and fixed through bearing seats at two ends, and one section of the shaft penetrates through the bearing seats to be connected with the shaft coupling, the speed reducer and the motor.

The utility model has the advantages that: the single-roller crusher has the characteristics of simple manufacture, high strength, good wear resistance and the like, so that the manufacture is simpler and more wear-resistant, the service life of the single-roller crusher is prolonged, the continuous production time of the sintering machine is prolonged, the maintenance times are reduced, and the operation rate of the sintering machine is improved.

Detailed Description

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are based on the orientations and positional relationships illustrated in the drawings and are used merely for convenience in describing the present invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the present invention unless otherwise specified.

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1-3, a crushing tooth applied to a single-tooth roller crusher comprises a tooth roller 5 and a base 603 mounted on the tooth roller 5, wherein a hardfacing layer 604 is coated on the surfaces of the tooth roller 5 and the base 603.

Furthermore, the base body 603 is in a solid cuboid shape, the end, contacting the base body 603 with the gear roller 5, is a tooth root, the end far away from the gear roller 5 is a tooth tip, the wear-resistant surfacing layer 604 is gradually thickened along the direction from the tooth root of the broken tooth 6 to the tooth tip, the thickness of surfacing on the tooth root and the gear roller 5 is 8-12mm, and the thickness of surfacing at the tooth tip is 20-30 mm.

Further, the toothed roller 5 is integrated with the base 603 in an integral structure.

Furthermore, a shaft hole used for being connected with a shaft is formed in the middle of the gear roller 5, the shaft is supported and fixed through bearing seats at two ends, and one section of the shaft penetrates through the bearing seat 4 to be connected with the coupler 3, the speed reducer and the motor 1.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
