Description

Technical Field

[0001] This utility model relates to the field of titanium ore sorting technology, and in particular to a dry-wet linkage titanium concentrate sorting device. Background Technology

[0002] In titanium ore beneficiation processes, traditional methods mostly employ either single dry or wet separation techniques. While single dry separation, such as wind separation, can achieve preliminary classification by utilizing differences in material mass and density, it suffers from low separation accuracy, poor handling of fine-grained materials, and easy dust pollution. Single wet separation, such as wet magnetic separation, can effectively separate magnetic minerals, but it requires high particle size uniformity. When processing titanium ore with high mud content or complex particle size distribution, magnetic agglomeration easily occurs, leading to decreased separation efficiency and increased costs and energy consumption in subsequent dewatering processes. Furthermore, existing separation equipment is mostly an open-loop system, unable to recycle unseparated materials, resulting in resource waste and failing to meet current demands for efficient and environmentally friendly titanium ore separation. Therefore, there is an urgent need to develop a new titanium ore separation device that combines the advantages of both dry and wet methods to achieve multi-stage screening and precise separation of materials.

[0003] Therefore, the existing titanium ore sorting technology needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a wet-dry linkage titanium concentrate sorting device, which uses wind power to blow raw materials to wet magnetic separators at different locations for multi-stage screening, and uses a material circulation system to repeatedly process unsorted materials, thereby improving the sorting accuracy, recovery rate and grade of titanium concentrate, reducing energy consumption and pollution, and meeting the needs of efficient industrial sorting.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A wet-dry linkage titanium concentrate separation device includes a separation channel, a fan at one end of the separation channel, a raw material input port above the separation channel, multiple wet magnetic separators evenly distributed along the airflow direction in the separation channel, and a material circulation device installed on the separation channel below the raw material input port.

[0007] Furthermore, the raw material inlet is located above the direction of the fan's airflow.

[0008] Furthermore, the material circulation device includes a return box disposed below the sorting channel, and the return box is provided with a screw rod return transmission device for circulating the material back to the raw material input port.

[0009] Furthermore, the opening above the reflux box and the opening below the raw material input port are aligned.

[0010] Furthermore, the wet magnetic separator includes a detachable magnetic cylinder structure, and the surface of the detachable magnetic cylinder structure is provided with spirally raised guide ridges.

[0011] Furthermore, the magnetic cylinder adopts a multi-layer composite magnetic system structure, consisting of an outer layer of high coercivity permanent magnets and an inner layer of adjustable electromagnetic coils.

[0012] Furthermore, the sorting channel is equipped with an adjustable-angle guide plate assembly, which includes multiple guide plates arranged alternately along the airflow direction.

[0013] Furthermore, the fan is a variable frequency speed control fan.

[0014] Furthermore, a vibrating feeder is provided at the raw material input port.

[0015] In summary, the advantages of this utility model over the prior art are:

[0016] This invention addresses the shortcomings of existing titanium ore sorting technologies. Through its structural design, it offers the following advantages: multi-stage screening for high efficiency and precision. By using wind power to propel the raw material to different positions in a wet magnetic separator for multi-stage screening, efficient grading and sorting of titanium ore raw materials based on quality and magnetic properties are achieved. Closed-loop circulation improves recovery rate: the material circulation device forms a closed-loop sorting system, repeatedly processing unsorted materials, reducing tailings loss and improving resource utilization. Energy saving and environmental protection: the dry-wet combined sorting method integrates the advantages of dry wind grading and wet magnetic separation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-2This utility model provides a wet and dry linkage titanium concentrate separation device, including a separation channel 1, a blower 2 at one end of the separation channel 1, a raw material input port 3 above the separation channel 1, a plurality of wet magnetic separators 4 evenly distributed in the separation channel 1 along the airflow direction, and a material circulation device 5 below the raw material input port 3 on the separation channel 1.

[0021] Raw material dispersion and air classification: After being uniformly dispersed by the vibrating feeder 100 set at the raw material input port 3, the titanium ore raw material enters the sorting channel 1 from the raw material input port 3.

[0022] The variable frequency speed-regulating fan 2 at one end of the sorting channel 1 generates a stable airflow of 6-12 m / s. Due to the differences in the trajectory and speed of titanium ore raw materials with different masses and densities under the action of wind, materials with smaller mass and lower density, such as gangue and other impurities, are blown to a farther distance in the sorting channel 1, while materials with larger mass and higher density, such as ilmenite, settle at a relatively closer distance or move at a slower speed, thus achieving preliminary wind classification.

[0023] During this process, the blower 2 is linked with the wind speed sensor in the sorting channel 1 to adjust the rotation speed in real time to maintain a stable wind speed. At the same time, the vibration frequency of the vibrating feeder 100 is linked with the wind speed parameter of the blower 2 to ensure that the material is evenly dispersed into the sorting channel 1.

[0024] Wet magnetic separation screening: Multiple wet magnetic separators 4 are evenly distributed in the sorting channel 1 along the airflow direction, and selectively screen materials at different positions according to the distribution position of the materials under the action of wind.

[0025] When magnetic ilmenite passes through the wet magnetic separator 4, it is adsorbed onto the surface of the magnetic drum under the combined action of the magnetic field and the water flow. The magnetic drum of the wet magnetic separator 4 adopts a multi-layer composite magnetic system structure, consisting of an outer layer of high-coercivity permanent magnets and an inner layer of adjustable electromagnetic coils. By adjusting the current of the electromagnetic coils, the magnetic field strength on the surface of the magnetic drum can be continuously adjusted within the range of 0.8-1.8T to meet the separation requirements of ilmenite materials with different magnetic strengths. The spiral-shaped protruding guide ridges on the surface of the magnetic drum guide the adsorbed magnetic material to move along the axis of the magnetic drum to the concentrate collection port, completing the collection of magnetic minerals; non-magnetic materials such as gangue continue to move with the airflow and are eventually discharged from the end of the separation channel 1.

[0026] Material recycling and reprocessing: Materials not effectively adsorbed by the wet magnetic separator 4 fall into the return box 501 below the sorting channel 1 under the action of gravity. The screw rod return conveyor 502 in the return box 501 transports the material back to the raw material input port 3, and re-enters the sorting process until it is effectively sorted, forming a closed-loop sorting system.

[0027] Airflow and material trajectory optimization: The adjustable-angle guide plate assembly inside the sorting channel 1 precisely controls the airflow path and material movement trajectory by adjusting the angle of the guide plates. This allows titanium ore raw materials of different qualities to be moved more accurately to the corresponding positions of the wet magnetic separator 4 for screening, further improving the grading accuracy. The hydrophobic nano-coating on the surface of the guide plates prevents the adhesion of fine mud in the material, ensuring effective airflow and grading of the material.

[0028] Stable equipment operation guarantee: The temperature sensor of the adjustable electromagnetic coil layer inside the wet magnetic separator 4 is electrically connected to the heat dissipation device. When the temperature of the electromagnetic coil layer exceeds the preset threshold, the heat dissipation device will automatically start to cool down, ensuring the stability of the magnetic field strength of the magnetic drum. The detachable magnetic drum structure is connected to the frame of the wet magnetic separator 4 through quick-release buckles with anti-loosening structure, which facilitates quick replacement of the magnetic drum and prevents the magnetic drum from loosening during equipment operation, ensuring safe and stable separation work.

[0029] The raw material input port 3 of this invention is located above the wind direction of the fan 2.

[0030] The material circulation device 5 of this utility model includes a return box 501 disposed below the sorting channel 1, and a screw rod return transmission device 502 for circulating the material back to the raw material input port 3 is disposed in the return box 501.

[0031] The opening above the reflux box 501 and the opening below the raw material input port 3 of this utility model are aligned.

[0032] The wet magnetic separator 4 of this utility model includes a detachable magnetic cylinder structure, and the surface of the detachable magnetic cylinder structure is provided with spiral protruding guide ridges.

[0033] The magnetic cylinder of this invention adopts a multi-layer composite magnetic system structure, consisting of an outer layer of high coercivity permanent magnet and an inner layer of adjustable electromagnetic coil.

[0034] The sorting channel 1 of this utility model is provided with an adjustable angle guide plate assembly, which includes multiple guide plates arranged alternately along the airflow direction.

[0035] The fan 2 described in this utility model is a variable frequency speed control fan.
