Description

Technical Field

[0001] The invention relates to the technical field of tailings sand screening, and in particular to a tailings sand grading screen magnetic separation and flotation metal device and a process thereof. Background Art

[0002] In the traditional tailings sand classification and screening process, mechanical transmission screening equipment is usually used. The transmission structure of such equipment is mostly mechanically designed. For precision manufacturing and precision assembly, the transmission through mechanical equipment can achieve the screening effect;

[0003] However, in actual work, the dust generated during the tailings sand screening process has a great impact on the mechanical equipment. Secondly, the amplitude requirement cannot be met, which further reduces the fineness of the tailings sand screening.

[0004] In view of this, we propose a tailings sand grading screen magnetic separation flotation metal device and process. Summary of the Invention

[0005] In view of the defects in the prior art, the present invention provides a tailings sand grading screen magnetic separation and flotation metal device and process thereof to solve the impact of dust on the equipment and at the same time improve the fineness of tailings sand screening.

[0006] The present invention provides a tailings sand grading screen magnetic separation and flotation metal device, comprising: a conveyor; at least one screen magnetic separation and flotation section, the screen magnetic separation and flotation section comprising a main support frame, a screen magnetic mechanism and a flotation mechanism, the screen magnetic mechanism being mounted on the main support frame, and the flotation mechanism being arranged below the screen magnetic mechanism; wherein the screen magnetic mechanism comprises a grading screen, a vibration motor and a magnetic driving force component; the grading screen is located above the main support frame, the magnetic driving force component being mounted on the main support frame and magnetically connected to the grading screen; the flotation mechanism being arranged below the grading screen and used for water washing and material selection; the vibration motor being mounted on the grading screen, wherein the vibration motor is provided in multiple locations and evenly distributed on the grading screen; and at least one fixed liquid guide trough, the fixed liquid guide trough being arranged between the screen magnetic separation and flotation sections, wherein the material screened by the screen magnetic separation and flotation section is transported through the fixed liquid guide trough.

[0007] Furthermore, the flotation mechanism includes a guide trough and a flushing pipe. Multiple flushing pipes are provided and are located on both sides of the inner wall of the guide trough. One end of the guide trough communicates with one of the fixed guide troughs, and the other end of the guide trough communicates with another fixed guide trough. In actual use, the purpose of this design is to use water for flushing and transfer. The flushing pipe is connected to an external water source. In actual operation, the water vapor brought by the impact can also effectively reduce dust, further avoiding the impact of dust on the equipment.

[0008] Furthermore, the grading screen is provided with no less than three specifications. In actual use, the purpose of this design is to achieve grading and screening.

[0009] Furthermore, the magnetic drive assembly includes a main mounting ring frame and an electromagnet; the main mounting ring frame is provided with a magnetic suspension inner groove, the electromagnet is mounted at the bottom of the magnetic suspension inner groove, and the grading screen is provided at the magnetic suspension inner groove; wherein, when the electromagnet is energized, the grading screen is magnetically driven to levitate. In actual use, the purpose of this design is to achieve the suspension of the grading screen, thereby replacing the mechanical transmission design of the transmission. By changing the magnetic field of the electromagnet, that is, the current, the grading screen is moved up and down, effectively ensuring the integrity of the screening work. Moreover, the magnetic suspension design adopted not only facilitates disassembly, but also avoids the impact of dust on the equipment.

[0010] Furthermore, the magnetic driving force assembly also includes two anti-collision rubber sleeves, which are installed in the magnetic suspension inner groove and abut the grading screen. In actual use, the purpose of this design is to protect the grading screen so that it can be effectively protected in the event of a collision.

[0011] Furthermore, the magnetic drive assembly also includes a bottom air sleeve, which is mounted on the main support frame and located below the main mounting ring frame, abutting the main mounting ring frame. In actual use, the purpose of this design is to achieve an air cushion effect to protect the main mounting ring frame.

[0012] Furthermore, the magnetic driving force assembly also includes a connecting cylinder, wherein at least two connecting cylinders are arranged on the outside of the main mounting ring frame and are evenly distributed along the center of the main mounting ring; wherein the output shaft of the connecting cylinder is connected to the outer wall of the main mounting ring, and the connecting cylinder is fixedly mounted on the main support frame. In actual use, the purpose of this design is to further increase the amplitude, increase the screening shaking amplitude, and form a three-level three-efficiency working effect with the above-mentioned electromagnet suspension adjustment and vibration motor vibration screening, effectively improving the screening range. Compared with the traditional eccentric wheel vibration speed regulation and amplitude design; this device can effectively avoid the impact of a single structure; and the combined design of the three vibration modes can not only increase the vibration amplitude over a wider range; but also the structure adopted by this device is more compact. The three vibration modes are independent of each other and affect each other, which greatly reduces the assembly precision requirements during the assembly process, thereby enabling long-term use in daily use, especially in dusty sites such as tailings sand, to meet industrial production requirements.

[0013] In summary, the beneficial effects of this tailings sand grading screen magnetic separation and flotation metal device are:

[0014] (1) In the actual production process, the tailings to be screened are transported by a conveyor and screened by the magnetic separation and flotation section, wherein the magnetic separation and flotation section is provided with a plurality of such sections, so that multi-stage screening can be performed, effectively ensuring the specifications of the ore material;

[0016] (3) Moreover, the grading screen is driven by the magnetic driving force component, effectively replacing the traditional mechanical gear transmission.

[0017] (4) In addition, the vibration motor used is small in size and can be directly installed on the grading screen to perform micro-vibration, further improving the screening efficiency.

[0018] In a second aspect, a tailings sand grading screen magnetic separation and flotation metal separation process comprises the following steps:

[0019] Step 1: Material screening: the tailings sand is introduced onto the grading screen under the transmission of the conveyor, and the vibration motor is started;

[0020] Step 2: Flotation, the tailings sand that falls into the diversion trough is washed and enters the fixed liquid guide trough, and flows into the grading screen in the next station, and this process is repeated;

[0021] Step 3: Gather materials.

[0022] In summary, the beneficial effects of this tailings sand grading screen magnetic separation and flotation metal separation process are as follows: in actual application, this method is easy to obtain and simple to operate. It avoids dust pollution and improves the environment of the production site. BRIEF DESCRIPTION OF THE DRAWINGS
