Description

Technical Field

[0001] This utility model relates to the field of multi-stage screening technology for mica sheet processing, and in particular to a multi-stage screening device for mica sheet processing. Background Technology

[0002] Mica flakes are a mineral material with a highly layered structure, composed of silicate minerals. Common colors include white, silver-white, and brown. Mica flakes of different sizes require different calcination temperatures for processing. Therefore, before processing mica flakes, screening equipment is needed to separate them and remove small particles of ore mixed in with the mica flakes.

[0003] Currently, Chinese utility model patent CN212143400U discloses a multi-layer grading sieve device for mica flake production, including a box body. A feed hopper is located at the center of the outer wall of the top of the box body. An installation shell is installed on the outer wall of the right side of the box body. Two sets of drive motors are located on the inner wall of the right side of the installation shell. A pulley is installed on the power end of the front side of the drive motor. During the screening process, the solenoid valve is in a closed state, and a sealing plate is inserted into the front end of the through hole. The drive motor drives the pulley and the driven pulley to rotate. The driven pulley drives the cam to rotate, causing the installation frame to move back and forth. The mica flakes falling into its inner cavity will be shaken and screened. Smaller diameter mica flakes fall down, while larger diameter mica flakes stay in the inner cavity of the installation frame in sequence. After no new material is added and screening is carried out for a period of time, the sealing plate can be removed so that the mica flakes at the top of the screen can enter the collection box for later collection, reducing the waste of mica flakes.

[0004] Before processing mica flakes, multi-stage screening equipment is required. Multi-stage screening equipment for mica flake processing is one such example. However, after screening mica flakes for a long time, the existing multi-stage screening equipment is not easy to disassemble, making it difficult to replace the screen plates when they are damaged. Furthermore, when screening mica flakes of different sizes, the screen plates need to be replaced repeatedly, which reduces the screening efficiency of mica flakes. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This multi-stage screening equipment for mica flake processing, through the setting of a limiting frame, fixing rod, spring, square fixing ring, screening box, vibrating motor, and adjusting components, allows the screening box to vibrate by starting the vibrating motor. During vibration, the square fixing ring, fixed to the screening box and connected to the fixing rod, causes the fixing ring to oscillate on the surface of the fixing rod due to the spring force, thereby increasing the vibration frequency of the screening box and improving its vibration effect. The mica flakes to be screened are then poured into the screening box, falling onto the adjusting components. The vibration of the screening box by the vibrating motor further enhances the screening effect. The screening box drives the adjustment component to vibrate, which vibrates the mica sheets. The vibration of the mica sheets on the adjustment component causes smaller mica sheets to fall downwards. A second vibration then performs secondary screening on the fallen mica sheets, thus achieving multi-stage screening. Larger mica sheets are guided out and collected through the discharge port under vibration. By pulling the adjustment component, it can be disengaged from the screening box for maintenance. When screening mica sheets of different sizes, the adjustment component can be rotated to change the aperture, thus avoiding the need for repeated screen plate replacements and improving the screening efficiency of the mica sheets.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Please see Figure 1-5This utility model provides a technical solution: a multi-stage screening device for mica sheet processing, including a limiting frame 1, a fixing rod 2, a spring 3, a square fixing ring 4, a screening box 5, a vibrating motor 6, and an adjusting component 7. The bottom of the fixing rod 2 is fixedly connected to the top of the limiting frame 1, the surface of the fixing rod 2 is in contact with the inner wall of the spring 3, one end of the spring 3 is fixedly connected to the top of the limiting frame 1, the other end of the spring 3 is fixedly connected to the bottom of the square fixing ring 4, the inner wall of the square fixing ring 4 is slidably connected to the surface of the fixing rod 2, the inner wall of the square fixing ring 4 is fixedly connected to the surface of the screening box 5, the bottom of the screening box 5 is fixedly connected to the top of the vibrating motor 6, and the surface of the adjusting component 7 is snapped into the inner wall of the screening box 5.

[0026] The adjusting assembly 7 includes a snap-fit ​​block 701, the surface of which snaps into the inner wall of the screening box 5. A limit box 702 is fixedly connected to the inner side of the snap-fit ​​block 701. The surface of the limit box 702 contacts the inner wall of the screening box 5. Adjusting threaded rods 703 are rotatably connected to both sides of the inner wall of the limit box 702. Adjusting blocks 704 are rotatably connected to the surface of the adjusting threaded rods 703. The surface of the adjusting blocks 704 contacts both sides of the inner wall of the limit box 702. A screening plate 705 is fixedly connected to the inner side of the adjusting blocks 704. The surface of the screening plate 705 contacts the inner wall of the limit box 702.

[0027] In this embodiment: by setting a limiting frame 1, a fixing rod 2, a spring 3, a square fixing ring 4, a screening box 5, a vibrating motor 6, and an adjusting component 7, the vibrating motor 6 can be started, thereby causing the screening box 5 to vibrate. When the screening box 5 vibrates, due to the fixing of the screening box 5 by the square fixing ring 4 and the connection between the square fixing ring 4 and the fixing rod 2, the square fixing ring 4 can swing on the surface of the fixing rod 2 due to the elastic force of the spring 3, thereby increasing the vibration frequency of the screening box 5 and improving its vibration effect. Then, the mica sheets to be screened are poured into the screening box 5, allowing them to fall onto the adjusting component 7. Finally, the vibration of the screening box 5 is assisted by the vibrating motor 6. The screening box 5 can drive the adjusting component 7 to vibrate, which can vibrate the mica sheets. The vibration of the mica sheets on the adjusting component 7 causes smaller mica sheets to fall downwards. After vibrating again, the fallen mica sheets are screened a second time, thus achieving multi-stage screening. The larger mica sheets are guided out and collected through the discharge port 12 under vibration. Then, by pulling the adjusting component 7, the adjusting component 7 can be disengaged from the screening box 5, so that the adjusting component 7 can be inspected and maintained. When screening mica sheets of different sizes, the aperture of the adjusting component 7 can be changed by rotating it, thus avoiding the need to repeatedly replace the screen plate and improving the screening efficiency of the mica sheets.

[0028] As a technical optimization of this utility model, the top of the square fixing ring 4 is provided with limiting holes 8, and there are a total of eight limiting holes 8. The inner wall of the limiting holes 8 is slidably connected to the surface of the fixing rod 2.

[0029] In this embodiment: by setting the limiting hole 8, the square fixing ring 4 can be easily connected to the fixing rod 2 under the fixing of the square fixing ring 4, and the stability of the square fixing ring 4 can be improved under the action of the limiting hole 8.

[0030] As a technical optimization of this utility model, a placement groove 9 is provided on the left side of the screening box 5. The placement groove 9 is trapezoidal, and the inner wall of the placement groove 9 is in close contact with the surface of the limiting box 702.

[0031] In this embodiment: by setting the placement groove 9, the installation position of the limiting box 702 can be limited under the fixed position of the screening box 5, so as to prevent the installation position of the limiting box 702 from shifting.

[0032] As a technical optimization of this utility model, the two sides of the placement groove 9 are provided with snap-fit ​​grooves 10. The snap-fit ​​grooves 10 are rectangular, and the inner wall of the snap-fit ​​grooves 10 is provided with protrusions 11. The surface of the protrusions 11 is in contact with the surface of the snap-fit ​​block 701.

[0033] In this embodiment: by setting the snap-fit ​​groove 10 and the protrusion 11, the protrusion 11 can be fixed under the fixed placement groove 9, and can also help guide the snap-fit ​​block 701 to snap-fit ​​groove 10. Through the action of the protrusion 11, the snap-fit ​​block 701 can be fixed, thereby improving the stability of the snap-fit ​​block 701 in use.

[0034] As a technical optimization of this utility model, a discharge port 12 is provided on the front side of the screening box 5, and a guide plate 13 is fixedly connected to the front side of the discharge port 12. The rear side of the guide plate 13 is fixedly connected to the front side of the screening box 5.

[0035] In this embodiment: by setting the discharge port 12 and the guide plate 13, the screened mica sheets can be easily discharged under the fixed position of the screening box 5, and the discharge position of the mica sheets can be guided by the guide plate 13, thereby facilitating the collection of mica sheets.

[0036] As a technical optimization of this utility model, a reinforcing block 14 is fixedly connected to the top of the vibration motor 6, and the top of the reinforcing block 14 is fixedly connected to the bottom of the screening box 5.

[0037] In this embodiment: by setting the reinforcing block 14, the vibrating motor 6 can be easily fixed to the screening box 5 under the fixed condition of the vibrating motor 6. Furthermore, under the action of the reinforcing block 14, the connection stability between the vibrating motor 6 and the screening box 5 can be increased, preventing the vibrating motor 6 from falling off under long-term vibration.

[0038] As a technical optimization of this utility model, a circular block 15 is provided on the surface of the snap-fit ​​block 701. The surface of the circular block 15 contacts the inner wall of the snap-fit ​​groove 10, and the two sides of the circular block 15 contact the two sides of the protrusion 11.

[0039] In this embodiment: by setting a circular block 15, the engagement position of the snap-fit ​​block 701 can be limited under the fixation of the snap-fit ​​block 701, and the engagement stability between the snap-fit ​​block 701 and the snap-fit ​​groove 10 can be increased.

[0040] As a technical optimization of this utility model, a guide groove 16 is provided on the surface of the limiting box 702. The guide groove 16 is positioned horizontally with the screening plate 705, and the bottom of the guide groove 16 is in contact with the top of the screening plate 705.

[0041] In this embodiment: by setting the guide groove 16, the poured mica sheets can be guided under the fixation of the limiting box 702, thereby improving the screening efficiency of the mica sheets. At the same time, when the screening plate 705 is adjusted, the aperture of the guide groove 16 can be changed by moving the screening plate 705, thereby screening mica sheets with different diameters and avoiding the need to repeatedly replace the screening plate.

[0042] Working principle: First, the adjusting threaded rod 703 is rotated, which causes the adjusting block 704 to move. Because the adjusting block 704 is fixedly connected to the screening plate 705, the position of the screening plate 705 can be adjusted. After the position of the screening plate 705 is adjusted, it blocks the guide groove 16, thus adjusting the diameter of the guide groove 16 to the required size. Then, the vibrating motor 6 is started, causing the screening box 5 to vibrate. During the vibration of the screening box 5, the square fixing ring 4, which fixes the screening box 5, and the connection between the square fixing ring 4 and the fixing rod 2, allow the square fixing ring 4 to move. The fixed ring 4 oscillates on the surface of the fixed rod 2 due to the elastic force of the spring 3, thereby increasing the vibration frequency of the screening box 5 and improving its vibration effect. Then, the mica flakes to be screened are poured into the screening box 5, allowing them to fall onto the limiting box 702. The vibration of the vibration motor 6 causes the mica flakes to vibrate on the limiting box 702. Smaller mica flakes can then fall from the limiting box 702 into the screening box 5 for further vibration, thus achieving multi-stage screening of the mica flakes. Finally, the screened mica flakes are discharged through the discharge port 12 by vibration, thus completing the multi-stage screening of the mica flakes.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
