Description

Jaw crusher

Technical Field

The invention relates to the technical field of crushing machinery, in particular to a jaw crusher.

Background

Jaw crushers are also called jaw crushers, jaw crushers and are first crushing machines commonly used for coarse crushing of industrial ore materials. When the jaw crusher operates, the motor is used as power, the triangular belt and the grooved pulley drive the eccentric shaft to make the jaw reciprocate in preset track, so as to crush material entering the crushing cavity comprising fixed jaw plate, movable jaw plate and casing and discharge the crushed material via the lower discharge port. The jaw crusher has stable performance, strong crushing capability and unique structural design, can prevent blockage and jamming and is widely used in the ore processing production line at present.

However, the existing jaw crusher has certain problems in the use in the calcium ore production line. The calcine is not true metallic calcine but is calcium oxide and/or calcium carbonate ore. The ore is easy to absorb water, releases heat after absorbing water, is corrosive, and can damage the jaw plate of the existing jaw crusher, and the service life of the jaw plate is generally short when the existing jaw crusher treats the ore.

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention provides a jaw crusher which can blast, dehumidify and cool the interior of the crusher during operation, reduce the corrosion of calcium ore to equipment and prolong the service life of the equipment.

The technical scheme for solving the technical problems is as follows: the utility model provides a jaw crusher, includes casing, flywheel, moves jaw and fixed jaw, still include with move the jaw through hinge bar swing joint's adjustment seat, fixed jaw surface is fixed and is provided with fixed jaw board, the ventilation hole has evenly been seted up on the fixed jaw board, fixed jaw is inside to be provided with the cavity fixed mounting has the fan in the cavity, ventilation hole and the inside cavity intercommunication of fixed jaw.

On the basis of the technical scheme, the invention can be further improved as follows.

Furthermore, the outer surface of the movable jaw plate on the surface of the movable jaw is provided with a protrusion part for crushing.

Preferably, the protrusion is cylindrical in shape.

Furthermore, the outer surface of the fixed jaw plate is provided with a protrusion for crushing.

Preferably, the protrusion is in a shape of a triangular frustum or a trapezoidal frustum.

Further, the aperture of the vent hole is 1-3 mm.

Furthermore, the fixed jaw plate and the movable jaw plate are made of high-strength corrosion-resistant tungsten steel.

The invention has the beneficial effects that: the invention can perform blast dehumidification and cooling on the inside of the crusher during operation, effectively prevent calcium ore residues from being adhered to the jaw plate, simultaneously effectively reduce the absorption of calcium ore to water, greatly reduce the corrosion of the calcium ore to equipment and greatly prolong the service life of the equipment.

in the figure: 1. the device comprises a shell, 2, a flywheel, 3, a movable jaw, 4, a fixed jaw, 41, a fixed jaw, 42, a fan, 43, a protrusion, 44, a vent hole, 5, a movable jaw, 51, a protrusion, 6, a feeding hole, 7, an adjusting seat, 8 and a hinge rod.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1, the jaw crusher of the present invention comprises a housing 1, a flywheel 2, a movable jaw 3, a fixed jaw 4, and an adjusting seat 7 movably connected to the movable jaw 3 via a hinge rod 8. The fixed jaw 4 is vertically installed at one side in the machine shell 1, the movable jaw 3 is installed opposite to the fixed jaw, and the movable jaw 3 is driven by the flywheel 2 to do reciprocating motion. An adjusting seat 7 is further installed in the machine shell 1 and is movably connected with the movable jaw 3 through a hinged rod 8 for adjusting the size of the discharge port.

As shown in fig. 2 and 3, a fixed jaw plate 41 is fixedly arranged on the outer surface of the fixed jaw 4, vent holes 44 are uniformly formed in the fixed jaw plate 41, a cavity is formed in the fixed jaw 4, a fan 42 is fixedly arranged in the cavity, and the vent holes 44 are communicated with the cavity in the fixed jaw 4.

As shown in fig. 3 to 5, the present invention provides a modified embodiment in which a protrusion 51 for pulverizing is provided on an outer surface of the movable jaw 5 on a surface of the movable jaw 3. The outer surface of the fixed jaw 41 is provided with a protrusion 43 for crushing.

Preferably, the protrusion 51 has a cylindrical shape.

Preferably, the protrusion 43 has a triangular frustum shape or a trapezoidal frustum shape.

Set up bulge 51 and arch 43, can make bulge 51 and arch 43 cooperation carry out the extrusion breakage to the calcium ore, crushing efficiency can improve by a wide margin, and the ore particle size after the breakage is comparatively even moreover, and the granularity is also finer.

In order to enhance the corrosion resistance and the strength, the fixed jaw 41 and the movable jaw 5 may be made of high-strength corrosion-resistant tungsten steel.

In order to prevent blockage, the invention also provides an improved technical scheme, and in the improved technical scheme, the aperture of the vent hole 44 is 1-3 mm.

The working principle of the invention is as follows:

when the invention is started, calcium ore is fed into the jaw crusher from the feed opening 6 and crushed by the movable jaw 3 and the fixed jaw 4. When the jaw crusher works, the fan 42 is started, cold air is continuously blown into the jaw crusher through the vent holes 44, air flow in the jaw crusher is accelerated, humidity and temperature are reduced, ore residues attached to the fixed jaw plate 41 can be blown away from the fixed jaw plate 41 when the jaw crusher works, and the jaw plate is effectively prevented from being corroded. Under the pressing and slapping of the fixed jaw 41 with the triangular frustum-shaped or trapezoidal frustum-shaped protrusion 43 and the movable jaw 5 with the cylindrical protrusion 51, the ore is crushed into ore particles with a relatively uniform particle size.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
