Description

Technical Field

[0001] This utility model relates to the field of quartz sand magnetic separator technology, and in particular to a quartz sand magnetic separator. Background Technology

[0002] A quartz sand magnetic separator is a device specifically designed to separate magnetic impurities from quartz sand. It utilizes the magnetic differences between different minerals to separate magnetic minerals (such as iron and titanium) from non-magnetic minerals (such as quartz and feldspar), thereby improving the purity of the quartz sand.

[0003] Patent application number 2023229873547 discloses a vertical ring magnetic separator for quartz sand. When using this separator, impurities are drawn from inside the rotor into the iron collection box and then extracted by a blower. This design is simple, easy to operate, and suitable for the orderly development of small businesses. However, when using this device, placing the material to be separated directly onto the conveyor belt may cause localized accumulation and unevenness of the sand. This not only affects the uniform conveying of the sand but may also hinder subsequent combing and magnetic separation processes due to excessive accumulation. Specifically, the sand forms an uneven layer thickness on the conveyor belt, with excessive sand accumulation in some areas and relatively less in others. This uneven distribution reduces conveying efficiency, increases equipment wear, and when the sand enters the subsequent processing unit, excessive local accumulation may lead to insufficient combing or uneven magnetic separation, thus affecting the overall processing effect and product quality. Utility Model Content

[0004] This invention proposes a quartz sand magnetic separator to solve the problem that existing magnetic separators, when placed directly on the conveyor belt, may cause local accumulation and uneven distribution, affecting conveying and subsequent processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand magnetic separator, comprising: a base, support plates installed on both sides of the base, a bearing plate installed on the top of the support plates, a conveying device installed on the end face of the base, a rotating wheel installed on the end face of the conveying device, a fixing plate connected between the two support plates, a threaded groove provided in the fixing plate, a threaded rod screwed through the threaded groove, a brush plate installed at the bottom end of the threaded rod via a bearing, a guide assembly installed between the fixing plate and the brush plate, brush bristles installed on the outer wall of the brush plate, and the brush plate being positioned between the feeding end of the conveying device and the rotating wheel.

[0006] Preferably, the guide assembly includes a sleeve and a rod, the sleeve being installed inside the fixed plate, the rod being connected to the outer wall of the brush plate, and a portion of the rod being located inside the sleeve.

[0007] Preferably, a push plate is provided on one side of the brush plate, a connecting plate is installed on the side wall of the push plate, and an adjustment component is provided between the connecting plate and the bearing plate.

[0008] Preferably, the positioning assembly includes an electric telescopic rod and a linear motor. The linear motor is mounted on the lower end face of the support plate, the electric telescopic rod is vertically connected to the output end of the linear motor, and the output end of the electric telescopic rod is fixedly installed with the connecting plate.

[0009] Preferably, an electromagnet is installed inside the rotor, and a material guide pipe is provided at the top of the rotor.

[0010] Preferably, a material collection box is installed at the discharge end of the material guide pipe, and a blower is installed at the air outlet end of the material collection box.

[0011] Preferably, the bottom end of the unloading end of the conveying device is provided with a collection trough, and a scraper is installed between the collection trough and the lower end face of the conveying device.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] (1) Adjust the position of the brush bristles by turning the threaded rod so that the brush bristles comb the sand before it enters the rotating wheel, effectively removing the unevenness and local accumulation on the surface of the sand, achieving uniform spreading of the sand, ensuring the consistent thickness of the sand layer, and reducing local accumulation, thereby avoiding the problem of affecting the subsequent magnetic separation process due to excessive accumulation.

[0014] (2) The push plate is moved by the electric telescopic rod and the linear motor to disperse the sand material piled up on the brush side near the feeding end, and push the sand material pile to the feeding end to disperse and spread evenly, which effectively avoids excessive accumulation of sand material in local areas and ensures that the sand material is evenly distributed on the entire conveying surface.

[0023] 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.

[0024] like Figures 1-6 As shown, a quartz sand magnetic separator includes: a base 1, support plates 2 installed on both sides of the base 1, a bearing plate 3 installed on the top of the support plate 2, a conveying device 4 installed on the end face of the base 1, a rotating wheel 5 installed on the end face of the conveying device 4, a fixing plate 8 connected between the two support plates 2, a threaded groove 9 opened in the fixing plate 8, a threaded rod 10 screwed through the threaded groove 9, a brush plate 6 installed at the bottom end of the threaded rod 10 through a bearing, a guide assembly installed between the fixing plate 8 and the brush plate 6, brush bristles 7 installed on the outer wall of the brush plate 6, and the brush plate 6 is positioned between the feeding end of the conveying device 4 and the rotating wheel 5. The specific structure and principle of the conveying device 4 are existing technologies, and can be referred to in the prior art (application number: 202322987354.7, title: A vertical ring magnetic separator for quartz sand), which will not be elaborated here.

[0025] Furthermore, the guide assembly includes a sleeve 11 and a rod 12. The sleeve 11 is installed inside the fixed plate 8, and the rod 12 is connected to the outer wall of the brush plate 6, with a portion of the rod 12 located inside the sleeve 11.

[0026] With the above technical solution: when in use, during the sand processing process, the sand is first transported to the conveying device 4. The conveying device 4 is responsible for transporting the sand along the predetermined path to the subsequent processing unit. Before the conveying starts, the operator needs to adjust the position of the brush bristles 7 by turning the threaded rod 10.

[0027] Tightening the threaded rod 10, through the cooperation between the threaded rod 10 and the threaded groove 9, controls the brush plate 6. Driven by the threaded rod 10, the brush plate 6 moves vertically. During the movement of the brush plate 6, the sleeve rod 12 slides within the sleeve 11. This design effectively restricts the lateral displacement of the brush plate 6, allowing it to move only vertically up and down, avoiding unnecessary left and right swaying, thereby improving system stability.

[0028] Operators should flexibly adjust the height of the brush bristles 7 according to factors such as the actual particle size distribution and moisture content of the sand.

[0029] The brush bristles 7 are used to comb the sand before it enters the rotor 5. This process can significantly remove unevenness and local accumulation on the sand surface. Specifically, the brush bristles 7 gently and effectively spread the sand evenly, eliminating surface irregularities and ensuring the consistency of the sand layer thickness. At the same time, the brush bristles 7 can also effectively reduce local accumulation of sand, avoiding the impact of excessive accumulation on the subsequent magnetic separation process. This pre-combing mechanism not only improves the flatness of the sand but also optimizes the magnetic separation effect. Since the sand has been uniformly treated before entering the rotor 5, the problem of uneven magnetic force caused by sand accumulation during the magnetic separation process is effectively alleviated, thereby improving the magnetic separation accuracy and efficiency. In addition, the uniform sand layer can reduce wear on the equipment and extend its service life. Thus, through the combing action of the brush bristles 7, the processing quality of the sand is significantly improved, providing more ideal raw material conditions for the subsequent magnetic separation process and ensuring the quality and purity of the final product.

[0030] In summary, through the above adjustment process, the device can be adjusted according to different types of sand, which not only ensures the efficiency of sand conveying but also improves the quality of magnetic separation.

[0031] Furthermore, a push plate 14 is provided on one side of the brush plate 6, and a connecting plate 13 is installed on the side wall of the push plate 14. An adjustment component is provided between the connecting plate 13 and the bearing plate 3.

[0032] The positioning assembly includes an electric telescopic rod 15 and a linear motor 16. The linear motor 16 is mounted on the lower end face of the support plate 3. The electric telescopic rod 15 is vertically connected to the output end of the linear motor 16, and the output end of the electric telescopic rod 15 is fixedly installed with the connecting plate 13.

[0033] Through the above technical solution:

[0034] During use, when the brush 7 is performing its combing function, it may obstruct the sand material, causing the sand material to accumulate on the side of the brush 7 near the feeding end.

[0035] To effectively solve this problem, the electric telescopic rod 15 and the linear motor 16 work together to achieve timely dispersion of the accumulated sand, as detailed below:

[0036] The electric telescopic rod 15 and the linear motor 16 are periodically activated to ensure timely response to the accumulation situation during the sand conveying process. The electric telescopic rod 15 is responsible for driving the push plate 14 in the vertical direction, while the linear motor 16 drives the push plate 14 to move in the horizontal direction.

[0037] During the sand processing, the electric telescopic rod 15 and the linear motor 16 work together to make the pusher plate 14 act on the sand pile. Then, the linear motor 16 drives the pusher plate 14 to move horizontally, pushing the sand pile to the upper end for dispersion and even spreading. This process effectively avoids excessive accumulation of sand in local areas, ensuring that the sand is evenly distributed across the entire conveying surface. Through this operation mechanism of positioning first and then dispersing, the pusher plate 14 can efficiently push away the accumulated sand, avoiding the impact on subsequent sand processing and conveying efficiency due to excessive local accumulation.

[0038] Through the dispersing effect of the push plate 14 and the combing effect of the brush 7, the device can effectively avoid the accumulation of sand and ensure that the sand remains in a uniform state during the conveying process, thereby improving the overall processing efficiency and effect. It not only solves the problem of sand accumulation that may occur during the combing process of the brush 7, but also further improves the combing quality of the sand through the synergistic work of the push plate 14 and the brush 7, providing more ideal raw material conditions for the subsequent magnetic separation process.

[0039] Furthermore, an electromagnet 17 is installed inside the rotor 5, and a material guide pipe 18 is provided at the top of the rotor 5.

[0040] A material collection box 19 is installed at the discharge end of the material guide pipe 18, and a blower 20 is installed at the air outlet end of the material collection box 19.

[0041] Specifically, in the sand processing flow, electromagnet 17 is installed at one end of the rotating wheel 5 near the conveying device 4. When the sand passes through the rotating wheel 5, the electromagnet 17 generates a strong magnetic field, effectively adsorbing magnetic impurities in the sand, causing them to detach from the sand and be attracted to the interior of the rotating wheel 5. As the rotating wheel 5 continues to rotate, the adsorbed impurities gradually move to the top of the rotating wheel 5. At this point, as the adsorption force of the electromagnet 17 gradually weakens, the impurities begin to separate from the rotating wheel 5. Then, the blower 20 uses negative pressure through the guide pipe 18 to suck the separated impurities out of the rotating wheel 5. The sucked-out impurities are transported to the collection box 19 through the guide pipe 18 for storage and collection, facilitating subsequent unified management and processing. This not only achieves effective separation of impurities in the sand, but also ensures proper handling of impurities through centralized collection in the collection box 19, avoiding secondary pollution to the environment. At the same time, the efficient operation of the system also improves the overall purity of the sand processing, providing higher quality raw materials for subsequent processes.

[0042] Furthermore, a collection trough 21 is provided at the bottom of the unloading end of the conveying device 4, and a scraper 22 is installed between the collection trough 21 and the lower end face of the conveying device 4.

[0043] Specifically, during the sand conveying process, the collection trough 21 is designed to collect sand that falls naturally from the conveying device 4 by gravity, ensuring that the sand can be effectively collected and conveyed to the subsequent processing unit; at the same time, the scraper 22 is installed between the collection trough 21 and the lower end face of the conveying device 4. During operation, the scraper 22 closely adheres to the lower end face of the conveying device 4, and through mechanical scraping, effectively reduces the adhesion of sand to the surface of the conveying device 4.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
