Abstract

A Raymond pulverizer. In an inner chamber of a round rolling wall (4), a roller (3) rolling on an inner surface of the rolling wall (4) to grind and pulverize an ore is directly mounted on a periphery of a central flower shelf (2). In the present application, a swinging arm of a suspended roller on the periphery of the flower shelf of the Raymond pulverizer is cancelled, eliminating a basic cause leading to the distortion and deformation of the flower shelf, and eliminating noise generated by the rotation of the swinging arm of the suspended arm due to unsmooth flower shelf in a process the Raymond pulverizer crushes the core. In addition, for the pulverizer having a chassis with a same diameter, because a diameter of the flower shelf for mounting the roller is increased, a periphery of the flower shelf is increased simultaneously, and the number of mounted rollers can be increased; therefore, the amount of the pulverized ore is also increased in the same time.

Description

Improved structure of Raymond shredder

Technical field

The present invention relates to a Raymond shredder for crushing ore.

Background technique

The existing Raymond pulverizer, in the process of crushing the ore powder, mainly drives the central flower stand directly connected thereto with the motor located under the chassis of the pulverizer, and rotates the roller suspended around the center flower stand. Under the action of the centrifugal force, the centrifugal force generated by the rotation of the roller pushes the crushing force to the crushing wall under the suspension, thereby crushing the ore that is caught between the roller and the crushing wall into a powder.

However, since the rod-shaped rocker arm is connected at the upper end to the periphery of the center flower stand, the lower end is suspended above the bottom of the mill, and the space around the wall is rolled up, which looks like a pendulum suspension in the air, when the Raymond machine cavity is added After the ore, when the roller encounters a pile of ore, the pile of ore will have a relative blocking force on the roller, and the roller will have a reaction, and the reaction force will be transmitted to the center connected thereto through the rocker arm. The joint around the flower stand. When this reaction force is transmitted to the connection point through the rocker arm, the suspended rocker arm is transformed into a lever force, which acts on the periphery of the center flower stand, and the enlarged reaction force causes the center. The body at the joint of the flower stand suspension rocker is twisted and deformed. As a result, the Raymond pulverizer not only doubles the sound during the process of crushing the ore, but also has a strong vibration, which causes damage to the machine.

technical problem

It is an object of the present invention to provide a new structure of a Raymond shredder that can avoid distortion of the center flower stand and cause damage to the Raymond shredder.

Technical solution

Referring to Figure 1, we can see that the electric motor 1 of the current Raymond shredder is mounted below the chassis 5 and penetrates from the center of the chassis 5, and is fixedly coupled to the center of the center flower stand 2 above the chassis 5, A plurality of rocker arms 6 are suspended and mounted around the center flower stand 2, and the upper end of the rocker arm 6 is mounted in an active state around the center flower stand 2. The lower end of the rocker arm 6 is suspended from the movable roller 3, and the roller 3 is integrated with the center flower stand 2, and is surrounded by a circled wall ring at the upper surface of the chassis 5.

When the motor 1 under the chassis 5 is started, the center flower stand 2 is rotated rapidly, and the center flower stand 2 rotates to drive the rocker arm 6 which is suspended around the center flower stand 2 and the roller which is suspended and connected at the lower end thereof. 3. Following the synchronous rotation of the periphery of the center flower stand 2, the roller 3 is pushed toward the inner surface of the mill wall 4 in the suspension of the rocker arm 6 under the centrifugal force of the rapid rotation. Thereby, the ore sandwiched between the roller 3 and the mill wall 4 is subjected to crushing and crushing. In the process of squeezing and crushing, once the ore is stacked and blocked in front of the roller 3, the roller 3 is inevitably subjected to a strong reaction force, and the reaction force is transmitted to the periphery of the center flower stand 2 through the rocker arm 6. At the end, the peripheral joint of the central flower stand 2 is finally twisted and deformed, so that the crusher is eventually destroyed.

Beneficial effect

In order to eradicate this structural disadvantage, (refer to the structural diagram of FIG. 2), in the design structure of the present invention, the rocker arm 6 (FIG. 1) is removed, and the roller 3 is directly installed in the peripheral body of the center flower stand 2, A plurality of rollers located around the center of the flower stand 2 are movable around the center of the flower stand 2, and each of them can be re-sliding in a radial direction among the respective movable structures. When encountering a pile of ore, the roller 3 will slide along the center of the radial center flower stand 2 in the structure without the damage of the lever force of the rocker arm 6 and twist the center flower stand 2. Therefore, when the crushed ore is crushed between the grinding wall and the roller 3, The safety of the Raymond shredder is better guaranteed.

Embodiments of the invention

The present invention will be further described in detail below with reference to FIG. 2 and the embodiment:

As shown in FIG. 2, the motor 1 is disposed under the chassis of the Raymond shredder, and the main shaft of the motor 1 is fixedly coupled to the center of the center flower stand 2 above the chassis 5 via the center of the chassis 5, at the center of the flower stand 2 The periphery is provided with a plurality of rollers 3 which are free to slide along the radial direction. On the periphery of the assembly, above the chassis 5, a circular milled wall is provided.

When the operator starts the motor 1, the motor 1 drives the central flower stand 2 fixedly mounted at the upper end thereof to rotate rapidly around the central axis of the motor 1. The rapidly rotating central flower stand 2 will be generated synchronously with the speed of the rotation. Large centrifugal force. Under the push of this centrifugal force, the roller 3 installed around the center of the flower stand 2 is pressed against the peripheral mill wall 4 by the centrifugal force, and the roller 3 is driven by the center flower stand 2 along the inner surface of the mill wall 4. Rolling, and rolling in synchronous rolling, crushing the ore between the roller 3 and the mill wall 4, the ore is finally in a powder state during repeated rolling.
