Description

ore crushing device

technical field

The invention relates to a crushing device, in particular to an ore crushing device.

Background technique

In metallurgical, chemical and other industrial sectors, a large amount of raw materials need to be processed by crushers every year, and crushing machinery plays an important role in many sectors. For example, in order to separate useful ore into monomers in a mining plant, a crusher must be used to break the ore into the particle size required for the crushing process. In coking, sintering, ceramics, glass industry, powder metallurgy and other industries, crushers must also be used to crush materials to the size requirements of the next step; in chemical plants, chemical laboratories, etc., crushing machinery crushes raw materials to increase the size of materials. Surface area, shorten the chemical reaction time of materials, to achieve better preparation effect.

However, the current ore crushing devices, such as jaw crushers, roller crushers, etc., all have the disadvantages of large volume, high energy consumption, and uneven ore crushing particles, and are not suitable for ore crushing in indoor or other small places. Work.

Contents of the invention

Purpose of the invention: The purpose of the invention is to provide a small, energy-saving and efficient ore crushing device.

Technical solution: The ore crushing device includes a hammering device with a fixed plate and a workbench under the hammering device; an electromagnetic actuator and a hammering actuator are arranged under the hammering device, and an electromagnetic actuator is installed on the working table. The electromagnetic fixed head directly below the hammer head, and the hammer fixed head located directly below the hammer head; when the opposite sex is maintained between the electromagnetic fixed head and the electromagnetic head, the hammer device is fixed vertically between the workbench and the fixed plate While the guide rod between them moves downward, it drives the hammer moving head to punch down the ore placed on the hammer fixed head; when the polarity becomes the same, the hammer device drives the hammer moving head to move upward to the original position .

The workbench also includes a cam, a motor and a spring device located above the cam. The cam is connected to the motor through a transmission rod arranged horizontally. The motor drives the cam to rotate, thereby controlling the spring device to reciprocate up and down. The workbench also includes spring sleeves located on the left and right sides of the workbench, and the spring device reciprocates up and down in the spring sleeves.

The spring device comprises a spring, a spring barrel, a lower spring fixed block and an upper spring fixed block; the lower spring fixed block is fixed on the bottom of the spring barrel, the top of the spring is connected with the upper spring fixed block, and the bottom is connected with the lower spring fixed block. The force of the cam compression spring is smaller than the attraction force between the electromagnetic fixed head and the electromagnetic moving head.

Working principle: This invention adopts the reciprocating motion of electromagnetic and spring to realize the crushing of ore and make the particle size after crushing finer and more uniform. First put the ore to be crushed between the pounding fixed head and the heavy hitting moving head, and then control the electromagnetic moving head and the electromagnetic fixed head to maintain opposite sex attraction through the control box until the two keep in contact. At this time, the transmission plate and the The upper fixed block contacts and compresses the spring downward; the motor controls the cam to rotate to the highest point, at this time the cam compresses the spring to the maximum elastic potential energy, wherein the force of the cam compressing the spring is less than the attraction force between the electromagnetic fixed head and the electromagnetic moving head. The electromagnetic moving head and the electromagnetic fixed head change the polarity to become the same. At this time, due to the release of the potential energy of the spring and the mutual repulsion of the electromagnetic polarity, the fixed plate rises to a high position, and the thumping moving head is also carried to a high position. At this time, The fixed plate and the fixed block on the spring are in a separated state; then the magnetism is changed again, so that the electromagnetic moving head and the electromagnetic fixed head become opposite sexes, and at this moment, the spring sinks as a whole due to the downward movement of the cam, and at the same time due to the gravitational potential energy, and The opposite sex is maintained between the electromagnetic moving head and the electromagnetic fixed head, which realizes that the transmission plate not only has the gravitational potential energy but also has the kinetic energy carried by the magnet, which drives the hammer moving head to hit the ore downward; with the reciprocating motion of the cam control spring and The change of the polarity of the electromagnet ensures the purpose of the device to continuously and efficiently crush the ore.

Beneficial effects: Compared with the prior art, the present invention has the following advantages: (1) can continuously and efficiently crush ore; (2) make the particle size after crushing finer and more uniform; (3) miniaturization and energy saving .

Detailed ways

As shown in Figure 1, the crushing device includes a worktable 1, a guide rod 2 and a hammering device 3. The working table 1 includes a transmission rod 11 arranged transversely, a cam 12, a motor 13, an elastic device 14, an electromagnetic fixed head 15 and a hammering device. The fixed head 16, and the spring sleeve 17 embedded in the table of the workbench 1, after the transmission rod 11 is fixedly connected with the left and right side cams 12, one end of the rod is connected with the motor 13; Moving spring barrel 141, spring 142, fixed block 143 under the spring and the spring upper fixed block 144 that is fixed on the spring barrel 141 bottom, the spring 142 top is welded with the upper fixed block 144, and the bottom end is welded on the lower fixed block 143; The top is in contact with the spring tube 141; the upper surface of the workbench 1 is fixedly connected with the guide rod 2, the electromagnetic fixed head 15 and the hammer fixed head 16, the guide rod 2 is connected with the hammer device 3 through the guide rod sleeve 31, and the fixed plate is 34 The surface is fixed with an electromagnetic moving head 32 and a heavy hitting moving head 33 .

When in use, put the ore that needs to be broken in the hammering fixed head 16 in advance; Keep the opposite sex, realize the strong attraction of the two, until the electromagnetic moving head 32 and the electromagnetic fixed head 15 keep in contact, at this time, the lower surface of the fixing plate 34 keeps in contact with the upper fixing block 144 of the spring, and compresses the spring 142 downward; at the same time, the motor 13 controls The cam 12 rotates to the highest point; subsequently, the polarity between the electromagnetic moving head 32 and the electromagnetic fixed head 15 is changed into the same, so that the percussion device 3 rises to a high position, and is in a separated state with the fixed block 144 on the spring; then change the magnetism, then The electromagnetic moving head 32 and the electromagnetic fixed head 19 become opposites and attract each other, driving the pounding moving head 33 to pound the ore downward; then the above steps are continuously repeated.
