Description

Technical Field

[0001] This application relates to the field of fluorite tailings processing technology, and more specifically, to a fluorite tailings processing device. Background Technology

[0002] In the cement production industry, fluorite is often used as a mineralizer to lower the firing temperature and shorten the firing time of cement raw materials, thereby improving cement production efficiency and reducing energy consumption. With the increasing demands of the cement industry for raw material cost control and resource recycling, the recovery and processing of fluorite tailings generated during fluorite mining and processing, the extraction of effective components (such as calcium fluoride), and their application in cement production have become important research directions within the industry.

[0003] In the pretreatment stage of fluorite tailings, after crushing, impurities need to be removed by screening. In existing processes, vibrating screens are commonly used for single screening operations. However, due to the influence of previous beneficiation processes, fluorite tailings often contain residual fibrous impurities such as filter cloth fibers. These impurities are lightweight and have a small particle size difference from the tailings particles. The screening effect of a single vibrating screen can only separate large impurities and cannot effectively separate fibrous impurities from the tailings. Summary of the Invention

[0004] The purpose of this application is to provide a fluorite tailings treatment device that can solve the technical problem that a single vibrating screen cannot effectively separate fibrous impurities from fluorite tailings in the pretreatment stage of fluorite tailings.

[0005] This application provides a fluorite tailings treatment device, including a housing. The housing is divided into a vibrating filter chamber and an air classifier filter chamber that are interconnected from top to bottom. A discharge valve is provided at the connection between the vibrating filter chamber and the air classifier filter chamber. The top of the housing is provided with a feed inlet communicating with the vibrating filter chamber. One side of the housing is provided with a first tailings outlet communicating with the vibrating filter chamber. A vibrating filter assembly is provided inside the vibrating filter chamber. The discharge end of the vibrating filter assembly is connected to the first tailings outlet. The housing is provided with a drive assembly for driving the vibrating filter assembly. One side of the housing is provided with an air inlet communicating with the air classifier filter chamber. The side of the housing opposite to the air inlet is provided with an air outlet communicating with the air classifier filter chamber. The bottom of the housing is provided with a fiber impurity outlet and a second tailings outlet communicating with the air classifier filter chamber. The second tailings outlet is located near the air inlet.

[0006] Furthermore, the vibration filtering assembly includes a mounting frame, a filter screen, and multiple springs. The mounting frame is inclinedly disposed in relation to the vibration filtering chamber. The filter screen is fixed on the mounting frame. There are four springs, which are symmetrically disposed at the bottom of the mounting frame. Support blocks corresponding to each spring are fixed on the inner wall of the vibration filtering chamber. The bottom of the mounting frame is connected to the support blocks through the springs.

[0007] Furthermore, the drive assembly includes a drive motor, a first rotating shaft, and a cam. The first rotating shaft is rotatably disposed inside the housing, the drive motor is fixedly mounted on the outside of the housing, one end of the first rotating shaft extends outside the housing and is connected to the output shaft of the drive motor, and the cam is fixed on the rotating shaft and the edge of the cam is slidably connected to the bottom of the mounting bracket.

[0008] Furthermore, a vertical baffle is fixedly installed in the air separation filter chamber between the fiber impurity outlet and the second tailings outlet, and the air inlet is displaced above the vertical baffle.

[0009] Furthermore, the feeding valve includes a second rotating shaft, a star-shaped material cylinder, and a feeding motor. The second rotating shaft is rotatably disposed inside the housing. The star-shaped material cylinder is adapted to the connection between the vibrating filter chamber and the air separation filter chamber. The star-shaped material cylinder is fixedly disposed on the second rotating shaft. The feeding motor is fixedly installed on the outside of the housing. One end of the second rotating shaft extends outside the housing and is connected to the output shaft of the feeding motor.

[0010] Furthermore, a fabric assembly is fixedly installed in the air separation filter chamber directly below the discharge valve. The fabric assembly is located above the air inlet. The fabric assembly includes an inclined fabric plate and a plurality of material dispersing teeth uniformly fixed on the lower surface of the fabric plate. The material dispersing teeth are configured in at least two rows, with adjacent rows of material dispersing teeth staggered.

[0011] Furthermore, electric valves are provided at the first tailings outlet, the fiber impurity outlet, and the second tailings outlet.

[0012] The beneficial effects of this utility model are:

[0013] This invention solves the problem that single vibratory screening is difficult to remove fibrous impurities by using a vibratory filtration chamber and an air separation filtration chamber arranged vertically and working together. Large impurities are first separated by vibratory filtration, and then fibrous impurities are specifically removed by air separation. This improves the purification effect of fluorite tailings.

[0027] like Figure 1 and Figure 2As shown, this application provides a fluorite tailings treatment device, including a shell 1. The shell 1 is divided into a vibrating filter chamber 11 and an air-classifying filter chamber 12, which are connected to each other from top to bottom. A discharge valve 2 is provided at the connection between the vibrating filter chamber 11 and the air-classifying filter chamber 12. The top of the shell 1 is provided with an inlet 13 connected to the vibrating filter chamber 11. A first tailings outlet 14 connected to the vibrating filter chamber 11 is provided on one side of the shell 1. A vibrating filter assembly 3 is provided inside the vibrating filter chamber 11. The discharge end of the vibrating filter assembly 3 is connected to the first tailings outlet 14. A drive assembly 4 for driving the operation of the vibrating filter assembly 3 is provided on the shell 1. An air inlet 15 connected to the air-classifying filter chamber 12 is provided on one side of the shell 1. An air outlet 16 connected to the air-classifying filter chamber 12 is provided on the side of the shell 1 opposite to the air inlet 15. A fiber impurity outlet 17 and a second tailings outlet 18 connected to the air-classifying filter chamber 12 are provided at the bottom of the shell 1. The second tailings outlet 18 is located near the air inlet 15. In use, the air inlet 15 is connected to the air-classifying filter chamber 12 via a pipe. An external air source device is connected to the dust treatment equipment via a pipe at the air outlet 16. The fluorite tailings, after being crushed by the crusher, enter the vibrating filter chamber 11 through the feed inlet 13. During the operation of the vibrating filter component 3 driven by the drive component 4, large impurities in the tailings are separated and discharged from the first tailings outlet 14. The tailings after vibration filtration enter the air classifier filter chamber 12 through the discharge valve 2. The airflow generated by the air source device enters from the air inlet 15 and interacts with the tailings. Because the fibrous impurities are light, they move towards the air outlet 16 with the airflow and are eventually discharged from the fibrous impurity outlet 17. The tailings particles are discharged from the second tailings outlet 18 under their own gravity, thus achieving the graded removal of large impurities and fibrous impurities in the fluorite tailings. Through the vertical arrangement and synergistic effect of the vibrating filter chamber 11 and the air classifier filter chamber 12, large impurities are first separated by vibration filtration, and then fibrous impurities are specifically removed by air classification. This solves the problem that single vibrating screening is difficult to remove fibrous impurities and improves the purification effect of fluorite tailings.

[0028] like Figure 2As shown, the vibration filter assembly 3 includes a mounting frame 31, a filter screen 32, and multiple springs 33. The mounting frame 31 is inclinedly arranged in relation to the vibration filter chamber 11. The filter screen 32 is fixedly mounted on the mounting frame 31. Four springs 33 are provided, and the four springs 33 are symmetrically arranged at the bottom of the mounting frame 31. Support blocks 5 corresponding to each spring 33 are fixedly mounted on the inner wall of the vibration filter chamber 11. The bottom of the mounting frame 31 is connected to the support blocks 5 through the springs 33. Specifically, the upper end of the spring 33 is fixedly connected to the bottom of the mounting frame 31, and the lower end of the spring 33 is fixedly connected to the support blocks 5. When the drive assembly 4 drives the mounting frame 31 to vibrate, the springs 33 undergo elastic deformation and reciprocate to generate vibration, causing the filter screen 32 on the mounting frame 31 to vibrate synchronously. The fluorite tailings slide downward under the vibration of the inclined filter screen 32. Fine particles of tailings that conform to the aperture of the filter screen 32 and fibrous impurities fall through the mesh, while large impurities slide along the inclined surface to the first tailings outlet 14, thus achieving the screening and filtration of the tailings.

[0029] like Figure 1 and Figure 2 As shown, the drive assembly 4 includes a drive motor 41, a first rotating shaft 42, and a cam 43. The first rotating shaft 42 is rotatably disposed inside the housing 1, and the drive motor 41 is fixedly installed on the outside of the housing 1. One end of the first rotating shaft 42 extends outside the housing 1 and is connected to the output shaft of the drive motor 41. The cam 43 is fixed on the rotating shaft, and the edge of the cam 43 is slidably connected to the bottom of the mounting bracket 31. The drive motor 41 drives the first rotating shaft 42 to drive the cam 43 to rotate. Since the edge of the cam 43 is slidably connected to the bottom of the mounting bracket 31, during the rotation of the cam 43, the eccentric structure of the cam 43 will generate a periodic pushing force on the bottom of the mounting bracket 31. Combined with the elastic restoring effect of the spring 33, the mounting bracket 31 realizes reciprocating vibration under the combined drive of the periodic force of the cam 43 and the elastic force of the spring 33. Specifically, the cam 43 is an eccentric wheel. There are two cams 43, which are symmetrically arranged. The two cams 43 correspond one-to-one with the front and rear frames of the mounting bracket 31.

[0030] like Figure 2 As shown, a vertical baffle 6 is fixedly installed in the air separation filter chamber 12 between the fiber impurity outlet 17 and the second tailings outlet 18, and the air inlet 15 is positioned above the vertical baffle 6. The vertical baffle 6 clearly delineates the material separation area in the air separation filter chamber 12, preventing fiber impurities from being mixed into the qualified tailings at the second tailings outlet 18 due to airflow disturbance.

[0031] like Figure 1 and Figure 2As shown, the feeding valve 2 includes a second rotating shaft 21, a star-shaped material cylinder 22, and a feeding motor 23. The second rotating shaft 21 is rotatably mounted inside the housing 1. The star-shaped material cylinder 22 is adapted to the connection between the vibrating filter chamber 11 and the air-separated filter chamber 12. The star-shaped material cylinder 22 is fixedly mounted on the second rotating shaft 21. The feeding motor 23 is fixedly installed on the outside of the housing 1. One end of the second rotating shaft 21 extends outside the housing 1 and is connected to the output shaft of the feeding motor 23. When the feeding valve 2 is working, the feeding motor 23 drives the second rotating shaft 21 to rotate the star-shaped material cylinder 22, and the material flows into the vibrating filter chamber 11. After screening, the fluorite tailings fall into the feed trough of the star-shaped feed cylinder 22. As the star-shaped feed cylinder 22 rotates, the tailings carried in the feed trough of the star-shaped feed cylinder 22 are gradually transported to the air separation filter chamber 12. The amount of tailings transported can be quantitatively controlled to avoid the air separation effect from decreasing due to a large amount of material entering the air separation filter chamber 12 at one time, thus ensuring the stability and efficiency of the air separation process. The star-shaped feed cylinder 22 is composed of a central hub and multiple blades evenly distributed along the circumference. The blades are arranged radially and fixedly connected to the hub to form a "star" structure. The feed troughs are formed between adjacent blades.

[0032] like Figure 2 and Figure 3 As shown, a material distribution assembly 7 is fixedly installed in the air separation filter chamber 12 directly below the feed valve 2. The material distribution assembly 7 is located above the air inlet 15. The material distribution assembly 7 includes an inclined material distribution plate 71 and a plurality of material dispersing teeth 72 uniformly fixed on the lower surface of the material distribution plate 71. The material dispersing teeth are configured in at least two rows, with adjacent rows of material dispersing teeth 72 staggered. The fluorite tailings discharged from the feed valve 2 fall onto the material distribution plate 71 of the material distribution assembly 7. Under the action of gravity, the tailings slide down the inclined surface of the material distribution plate 71. During the slide, the material dispersing teeth 72 disperse the tailings. When the dispersed tailings particles slide down from the material distribution plate 71, they come into full contact with the horizontal airflow entering from the lower air inlet 15, thereby improving the separation efficiency of fibrous impurities and tailings particles and reducing impurity residue.

[0033] like Figure 2 As shown, electric valves 8 are installed at the first tailings outlet 14, the fiber impurity outlet 17, and the second tailings outlet 18. The electric valves 8 are existing technology and will not be described in detail here. The electric valves 8, the drive motor 41, and the feeding motor 23 are electrically connected to a control box, which controls their start-up. The electric valves 8 are used to control the discharge of relevant materials at the corresponding locations.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
