Description

Technical Field

[0001] This utility model relates to the field of quartz sand screening, and in particular to a magnetic suction device for quartz sand screening. Background Technology

[0002] Quartz sand plays an indispensable role in many key industrial sectors, from basic glass manufacturing to high-tech semiconductor and photovoltaic industries. As a core raw material in numerous industrial fields such as glass, ceramics, and electronics, the purity of quartz sand directly affects the quality and performance of downstream products. In the quartz sand processing, removing iron impurities is a crucial step in improving quality, and magnetic adsorption devices have become commonly used impurity removal equipment due to their high efficiency and convenience.

[0003] Current magnetic adsorption devices for quartz sand screening have fixed magnetic block positions, making it difficult to flexibly adjust them according to the impurity content and distribution of the quartz sand. This results in insufficient impurity adsorption, affecting the purification effect of the quartz sand. Moreover, the lack of an effective vibration-assisted structure leads to poor fluidity of the quartz sand in the sieve hopper, causing it to easily accumulate. This not only reduces screening efficiency but may also cause impurities to become trapped and unable to be effectively adsorbed by the magnetic blocks. Therefore, we propose a magnetic adsorption device for quartz sand screening to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic suction device for screening quartz sand, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnetic suction device for screening quartz sand includes a frame, a vertical plate at the rear of the frame, a moving mechanism connected to the front of the vertical plate, a sieve hopper inside the frame, two magnetic blocks inside the sieve hopper, vibration mechanisms connected to the left and right sides of the sieve hopper, and two positioning mechanisms embedded in the upper surface of the frame.

[0007] In a further embodiment, the moving mechanism includes a housing connected to a vertical plate. Two electric push rods are embedded in the inner sidewall of the housing. Each of the two electric push rods is connected to a movable plate at one end close to each other. A slider is connected to the front of each movable plate. A pull rope is connected to the bottom surface of each slider. The bottom end of each pull rope is connected to the upper surface of a magnetic block.

[0008] In a further embodiment, each of the vibration mechanisms includes a connecting plate connected to the sieve bucket, a vibration motor is connected to the upper surface of each connecting plate, and two springs are connected to the bottom surface of each connecting plate, with the bottom end of each spring connected to the upper surface of the frame.

[0009] In a further embodiment, each of the positioning mechanisms includes a slide cylinder embedded in the frame, and a slide rod is slidably connected to the inner wall of each slide cylinder, with the top end of each slide rod connected to the bottom surface of the connecting plate.

[0010] In a further embodiment, a fixing plate is connected to the bottom surface of the frame, and two sets of through holes are provided on the upper surface of the fixing plate.

[0011] In a further embodiment, a guide frame is provided below the screen hopper, and the bottom surface of the guide frame is connected to the inner bottom wall of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a vibrating motor to drive a connecting plate, which in turn causes a spring to repeatedly extend and retract, generating high-frequency vibration in the screen bucket. This significantly enhances the flowability of quartz sand within the screen bucket, preventing material accumulation and ensuring thorough dispersion of the quartz sand. It effectively reduces impurity encapsulation, allowing the magnetic blocks to more comprehensively adsorb magnetic impurities, thus greatly improving screening efficiency and impurity removal rate. The moving mechanism, with its electric push rod, movable plate, slider, and pull rope, allows for flexible adjustment of the magnetic block position. The position and height of the magnetic blocks can be precisely adjusted according to the actual distribution and content of impurities in the quartz sand, enabling the magnetic blocks to more broadly and specifically absorb magnetic impurities. The positioning mechanism, with its sliding rod and sliding cylinder, provides stable support for the connecting plate, effectively enhancing the structural stability of the screen bucket during vibration, preventing screen bucket deviation and shaking, ensuring the accuracy of the screening process, and extending the equipment's service life.

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.

[0022] Please see Figure 1-4 In this utility model, a magnetic suction device for screening quartz sand includes a frame 8, a vertical plate 10 at the rear of the frame 8, a moving mechanism 1 connected to the front of the vertical plate 10, a sieve hopper 4 inside the frame 8, two magnetic blocks 9 inside the sieve hopper 4, and vibration mechanisms 2 connected to the left and right sides of the sieve hopper 4. Two positioning mechanisms 3 are embedded on the upper surface of the frame 8. The magnetic blocks 9 are used to attract magnetic impurities. Then, the moving plate 102 is pushed by the thrust of the electric push rod 103. Then, the magnetic blocks 9 are moved by the slider 104 and the pull rope 105, and the magnetic blocks 9 are widely attracted to attract magnetic impurities, thereby completing the screening of quartz sand and greatly improving the screening efficiency and impurity removal rate.

[0023] The moving mechanism 1 includes a housing 101 connected to the upright plate 10. Two electric push rods 103 are embedded in the inner side wall of the housing 101. The ends of the two electric push rods 103 that are close to each other are connected to movable plates 102. Each movable plate 102 has a slider 104 connected to its front side. Each slider 104 has a pull rope 105 connected to its bottom surface. The bottom end of each pull rope 105 is connected to the upper surface of the magnetic block 9. The pushing force of the electric push rods 103 is used to push the movable plates 102 to move, and the sliders 104 and pull ropes 105 are used to drive the magnetic block 9 to move. This is beneficial for the magnetic block 9 to widely absorb magnetic impurities, thereby completing the screening of quartz sand.

[0024] Each vibration mechanism 2 includes a connecting plate 201 connected to the screen bucket 4. A vibration motor 202 is connected to the upper surface of each connecting plate 201, and two springs 203 are connected to the bottom surface of each connecting plate 201. The bottom end of each spring 203 is connected to the upper surface of the frame 8. With the power provided by the vibration motor 202 and the cooperation of the springs 203, the connecting plate 201 can drive the screen bucket 4 to vibrate, which also helps the quartz sand to move according to the vibration of the screen bucket 4.

[0025] Each positioning mechanism 3 includes a slide cylinder 301 embedded in the frame 8. A slide rod 302 is slidably connected to the inner wall of each slide cylinder 301. The top of each slide rod 302 is connected to the bottom surface of the connecting plate 201. The cooperation between the slide rod 302 and the slide cylinder 301 increases the stability of the connecting plate 201 and prevents the connecting plate 201 from causing the screen bucket 4 to tilt.

[0026] The bottom surface of the frame 8 is connected to a fixing plate 6. The upper surface of the fixing plate 6 is provided with two sets of through holes 7. The through holes 7 and the fixing plate 6 are used to facilitate the installation of the device in the place of use. The bottom of the screen hopper 4 is provided with a guide frame 5. The bottom surface of the guide frame 5 is connected to the inner bottom wall of the frame 8. The guide frame 5 is used to facilitate the guidance and discharge of quartz sand.

[0027] The working principle of this utility model is as follows:

[0028] In use, the power provided by the vibration motor 202 first causes the connecting plate 201 to repeatedly contract and extend the spring 203. At the same time, the connecting plate 201 causes the screen bucket 4 to vibrate. Then, the cooperation of the slide rod 302 and the slide cylinder 301 increases the stability of the connecting plate 201. At this time, the quartz sand is placed inside the screen bucket 4. The quartz sand moves according to the vibration of the screen bucket 4. Then, the magnetic block 9 is used to attract magnetic impurities. Next, the electric push rod 103 pushes the movable plate 102 to move. Then, the slider 104 and the pull rope 105 drive the magnetic block 9 to move, and the magnetic block 9 widely attracts magnetic impurities, thereby completing the screening of quartz sand.
