Working principle: When the mine-used multi-gradient drum type dry separator is in use, the rotation of the rotating part of the motor 12 drives the rotating rod 14 and the magnetic separation drum 3 to rotate, and due to the locking action of the fixed column 5 and the fixed plate 6 , so that the multi-gradient magnetic separation cylinder 4 remains stagnant, and then when the material falls on the surface of the magnetic separation cylinder 3 and is driven by the magnetic separation cylinder 3 to follow the rotation, the magnetic materials will be attracted, and the non-magnetic materials will be attracted. The raw material will be thrown to the left side of the magnetic separation shell 2 by the magnetic separation cylinder 3, as shown in Figure 2, and then achieve the effect of magnetic separation, and as shown in Figure 5, it is different from the existing fixed magnetic system. The method adds a multi-gradient magnetic system. The magnetic properties of the adsorption part 8, the sorting part 9, the purification part 10 and the discharge part 11 are different. Under the relationship between raw materials, there will be certain shaking and flipping of the raw materials, thereby improving the efficiency of magnetic separation, so that the non-magnetic raw materials doped in the magnetic raw materials can be unloaded more quickly. This method has the advantages of uniform separation and high separation effect , and the effect of thorough separation. During the sorting process, the power and frequency of material turnover are improved, and it has excellent magnetic separation effect.

By the operation of the motor-12 rotating part, the rotating rod 14, the magnetic selection cylinder 3 and the circular plate 16 are driven to rotate, and then the inner ring 15 can be driven to rotate, and the slide block 17 on the inner ring 15, the slide bar 19 and the knocking The batting ball 20 rotates, as shown in Figure 2 and , when the knocking ball 20 rotates and contacts with the knocking block 23, the knocking block 23 and the slide bar 19 will be contracted, thereby compressing the back-moving spring one 21 to make the knocking The beating ball 20 forms a certain elastic potential energy. When the beating ball 20 is far away from the single beating block 23, the elastic potential energy will be released, so that the beating ball 20 hits the inner wall of the multi-gradient magnetic separation cylinder 4, causing a certain vibration , and because there are many sets of knocking balls 20 and multiple knocking blocks 23, as shown in Figure 2, continuous shaking will occur at the position above the magnetic selection cylinder 3, and as the knocking balls 20 rotate, when When the knocking ball 20 is in contact with the arc block 24, and because the arc block 24 has a certain length and a certain thickness, the back-moving spring one 21 will continue to shrink, thereby forming a higher elastic potential energy. When the batting ball 20 is far away from the arc block 24, the elastic potential energy is released instantaneously so that the knocking block 23 impacts the inner wall of the multi-gradient magnetic separation cylinder 4, and then the corresponding position on the surface of the magnetic separation cylinder 3 is subjected to a relatively large impact force, corresponding to Looking at the area below the magnetic separation cylinder 3 in Fig. 2, this mode has possessed:

First: By continuously shaking the area above the magnetic separation cylinder 3, the raw materials falling on the surface of the magnetic separation cylinder 3 can be flattened to avoid uneven feeding caused by the accumulation of raw materials, and the subsequent When the structural resistance is large;

Second: By making the area under the magnetic separation cylinder 3 vibrate greatly, the raw materials that are still attached to the surface of the magnetic separation cylinder 3 are unloaded, and the impact force makes the area under the magnetic separation cylinder 3 have a greater vibration , thereby speeding up the feeding of the raw materials, avoiding the influence of the raw materials on the subsequent operation caused by the continuous attachment of the raw materials to the magnetic separation drum 3;

Third: The ball-shaped configuration of the knocking ball 20 reduces the friction between the knocking structure and the inner wall of the multi-gradient magnetic separation cylinder, thereby achieving the effect of reducing structural wear and improving mechanical efficiency.

When the raw material enters the device, the specification range of the batch of raw material can be known initially through the external detection device, and then the operation of the telescopic part of the electric push rod 29 is driven, which drives the material retaining plate 7 to move vertically, and then The thickness of raw material cutting and magnetic separation can be changed to avoid the poor magnetic separation effect of raw materials caused by the large thickness of the raw material when the raw material specification is too small, and when the raw material specification is large, it may be accumulated on the baffle plate 7 When the electric push rod 29 is adjusted, the synchronous operation of the rotating part of the driving motor 25 drives the bevel gear 1 26 to rotate, and under the relationship of meshing transmission, the conical gear The second gear 27 and the threaded rod 28 rotate, and then under the relationship of the screw transmission, the insert block 22 can be moved vertically, as shown in Figure 10, and because the knocking ball 20 is always connected with the multi-gradient magnetic selection cylinder 4 Therefore, with the operation of the insert block 22 relative to the slide plate 18, the return spring one 21 will be squeezed, so that the return spring one 21 is compressed, thereby reducing the contraction of the return spring one 21, and then knocking The hitting ball 20 is pressed against the knocking block 23 and the arc block 24 so that the elastic potential energy formed by the contraction of the return spring 1 21 increases, and then the impact force applied when the knocking block 23 hits the multi-gradient magnetic separation tube 4 It will be bigger, so the intensity of the vibration will also increase. This method has:

First: the baffle plate 7 can smooth the raw materials to avoid the uneven thickness of the raw materials to be magnetically separated on the surface of the magnetic separation cylinder 3, which may affect the magnetic separation effect;

Second: The distance between the baffle plate 7 and the magnetic separation cylinder 3 can be controlled directionally, so as to be suitable for situations where the thickness of the raw material is uneven and the raw material cannot be normally discharged when the raw material specification is large or small, and the The adjustment method can detect the specifications of the batch of raw materials through external sensors and manual operations, and make directional changes. Therefore, this method also has relatively high practicability. High automation performance;

Third: when the specification of the raw material is larger, the distance between the baffle plate 7 and the magnetic separation cylinder 3 is bound to become larger, so under the relationship of synchronous adjustment, the knocking of the knocking ball 20 on the magnetic separation cylinder 3 will be made. The impact strength becomes larger, thereby avoiding the appearance of raw materials with larger specifications. When knocking with a smaller force, the vibration is relatively limited, and it is impossible to turn over, flatten and unload all the raw materials. This method has a certain degree of self-adaptive adjustment. Efficacy, so this method not only has excellent magnetic separation effect, but also has better cutting effect.
