[0002] Most raw materials in industrial production cannot be separated from mineral resources, and the original mineral materials cannot be directly used and need to be processed through multiple processes and into products at different stages. In the rock mineral material industry, when sampling the sample containing powder and water minerals after coarse crushing, the minerals need to be dried and iron removed. In the prior art, the minerals are first dried, and then the dried minerals are iron removed. However, this technology has certain defects, that is, manual intervention is required in the drying and iron removal steps, and automatic production cannot be achieved, which not only reduces the work efficiency, but also causes loss of minerals.

[0005] Principle and effect of the technical scheme: the powder and water containing minerals are put into the vibrating feeder, and then the vibrating feeder, the drying box and the permanent magnet iron remover are started. After the vibrating feeder is started, the powder and water containing minerals are vibrated towards the material collecting bin. At this time, the minerals are conveyed into the drying box, the water in the minerals is dried in the drying box, and the dried minerals are finally conveyed below the permanent magnet iron remover. The magnetic substances in the minerals are adsorbed by the permanent magnet iron remover, so that pure mineral powder is obtained.

[0006] Further, the drying box is communicated with a moisture removal pipeline, and the moisture removal pipeline is provided with an air extractor. The moisture removal pipeline and the air extractor can timely remove the water vapor in the drying process, avoiding the situation that the water vapor falls back to the conveying belt and affects the purity of the product.

[0007] Further, the filter screen is arranged in the wet exhaust pipe, and a recycling box is communicated with the wet exhaust pipe on the side of the filter screen. The filter screen and the recycling box can recycle the small amount of minerals sucked in the wet exhaust process, and avoid the loss of minerals. BRIEF DESCRIPTION OF DRAWINGS

The machine body 25 and the connecting disc 26 are provided with a magnetic yoke 27 and a magnetic system 28; the power transmission device comprises a DC motor 29, a speed reducer 30, a driving gear 31 and a driven gear 32, the DC motor 29 and the speed reducer 30 are in transmission connection, the driving gear 31 is located on the output shaft of the speed reducer 30, the driven gear 32 is fixedly connected with the machine body 25, and the driving gear 31 and the driven gear 32 are in meshing engagement.

[0020] The working principle of the scheme is as follows: the powder and water minerals are put into the chute 3, and then the vibration motor 1, the electric heating wire 13, the air extractor 19 and the permanent magnet iron remover 22 are started, after the vibration motor 1 is started, the vibration motor 1 transmits mechanical vibration energy to the minerals in the chute 3 through the fixed frame 2 and the chute 3, so that the minerals can move to the right in the chute 3, and the mechanical vibration energy plays a spreading effect on the minerals, so that the accumulation of the minerals and the influence on the drying effect of the drying box are avoided. In the process of vibrating the fixed frame 2 and the chute 3 driven by the vibration motor 1, the connecting rod 9 and the damping spring 4 on the chute 3 can play a damping effect on the chute 3, so that the chute 3 is prevented from being in contact with other components in the vibration process and accelerated wear, and the service life of the chute 3 is prolonged; and the connecting rod 9 is vertically arranged with the chute 3, so that the vibration direction of the minerals in the chute 3 is consistent, and the conveying efficiency of the minerals is not affected by the inconsistent vibration direction.

[0021] When the mineral is conveyed to below the drying box, the electric heating wire 13 in the box 11 dries the moisture in the mineral in the chute 3 by heating, so as to facilitate the subsequent iron removal treatment of the mineral. In the process of drying the mineral by the drying box, the exhaust fan 19 removes the water vapor evaporated in the box 11 through the exhaust pipeline 18, so as to avoid the case that the water vapor flows back to the mineral and reduces the drying effect. When the water vapor moves along the exhaust pipeline 18, the water vapor is discharged after passing through the filter screen 20, and a small amount of mineral is mixed in the exhaust fan 19 in the rising process, and this part of the mineral is intercepted when moving to the filter screen 20. When the exhaust fan 19 is closed, the mineral on the filter screen 20 falls into the recovery box 21 under the action of gravity, so as to avoid the case that the mineral is lost.

[0022] When the mineral moves to directly below the permanent magnet iron remover 22, the permanent magnet iron remover 22 adsorbs the magnetic substances in the mineral powder on the connecting disc 26 by means of the magnetic area on the connecting disc 26, and finally the mineral after drying and iron removal falls into the collecting bin 33 under the action of the vibration motor 1, so that the automatic drying and iron removal operation of the mineral containing powder and water can be realized by means of the device, and finally the pure mineral is obtained.
