Description

Double-geared roller crusher for titanium chips

Technical Field

The invention relates to the field of crushers, in particular to a double-geared roller crusher for titanium chips.

Background

Along with the increasing of the total value of national production, the demand of titanium alloy as a distinctive strategic metal resource in our country is greatly increased. Because a large amount of titanium chips are generated during the machining. These wastes can severely impact the environment if not effectively disposed of. How to effectively recycle titanium chips, recycle the titanium chips and reduce the production cost of titanium materials is a future trend in the field of production and utilization of rare metals such as titanium and alloys thereof.

Most of crushers on the market are all to the ore crushing, and are less relatively to the less ductile metal crushers of hardness such as titanium bits, need a breaker to broken to ductile metal to promote recycle and rate, improve production efficiency.

Disclosure of Invention

The invention mainly aims at ductile metals such as titanium chips and the like which are not easy to break by the existing extrusion type crusher, and designs a double-geared roller crusher suitable for recovering titanium chips, so that the metals are crushed by shearing force.

The technical scheme of the invention is as follows:

the double-geared roller crusher for titanium chips comprises a hollow box body, a feeding hopper positioned on the upper portion of the box body, a supporting hopper positioned below the box body and a discharging hopper arranged on the upper portion of the box body, two rotary knife rollers which are horizontally arranged and rotate oppositely are placed in a cavity of the box body, knife teeth are distributed on the rotary knife rollers and matched with the smooth surface of the other knife roller to form a shear port, comb tooth check blocks are distributed between two axially adjacent knife teeth, a linkage gear is installed at the left end of each knife roller, a reduction gear is installed at one end of each driving knife roller, the driving knife rollers are fixed through nuts, and end covers are arranged on the left sides of the knife rollers for sealing. The front side and the rear side of the box body are provided with openable box doors, the upper ends of the box doors are connected through hinges, and the lower ends of the box doors are fixed through bolts. The left side of the box body is provided with a detachable baffle.

Openings are reserved on the front side and the rear side of the box body, and the roller teeth are convenient to overhaul. Two detachable movable baffle plates are arranged at the shaft hole of the right side of the box body, so that the knife roller is more convenient to mount.

The included angle between the front side and the rear side of the charging hopper and the vertical direction is 60 degrees, and 4 surfaces are assembled together by bolts and are arranged at the upper end of the box body.

The support frame is formed by welding hollow pipes. The discharge hopper is welded integrally and is installed on the support frame through bolts, the lower end of the discharge hopper extends outwards, and materials can be collected conveniently after being crushed.

The detachable toothed plate is fixed on the knife roll by bolts, and the tooth top part of the knife tooth is provided with a section of central circular arc, so that the roller teeth are highly matched.

The structure of the installation position of the toothed plate of the rotary knife roller is in a rotary step type, most of force borne by the toothed plate can be transmitted to the knife roller by the structure, and the force borne by a bolt is small.

The broach dog be detachable, select for use different models according to the fluted roller size of difference, by the bolt fastening on the box.

The upper ends of the front and the rear box doors are connected with the box body through three hinges, the lower ends of the front and the rear box doors are fixed through two bolts, and the box doors can be opened upwards by 180 degrees.

Compared with the existing crusher, the invention has the advantages that: the cutter teeth and the cutter roller rotate oppositely to form shearing mouths to crush titanium chips. The whole device is simple in structure, convenient to operate, convenient to install and detach and capable of achieving a good crushing effect on titanium chips. Rotatory cascaded fluted roller can make the most transmission of power that the pinion rack received give the rotor, and the shearing force that the construction bolt received is less. Go out the hopper and outwards extend, make things convenient for the material after the breakage to collect.
