Description

Technical Field

[0001] This utility model relates to the field of roughing of high-purity quartz sand, and in particular to a roughing device for the production of high-purity quartz sand. Background Technology

[0002] High-purity quartz sand is a type of quartz sand with extremely high SiO2 content and extremely low impurity content. Its extremely low impurity content gives it high temperature resistance, excellent chemical properties, and excellent electrical insulation and light transmittance.

[0003] In existing technologies, the preparation processes for high-purity quartz sand mainly include physical and chemical methods. Physical methods mainly include scrubbing, desliming, gravity separation, magnetic separation, and flotation, which can remove most mineral impurities that exist as monomers.

[0004] Through long-term use and observation, it was found that when using magnetic separation for roughing of quartz sand, blockages and interruptions in the material conveying process can cause material to accumulate inside the equipment, making continuous operation impossible.

[0005] Therefore, we propose a coarse separation device for the production of high-purity quartz sand. Utility Model Content

[0006] The technical solution of this utility model is: a roughing device for high-purity quartz sand production, including a roughing box, an inlet on the top side wall of the roughing box, a material distribution component below the inlet, an outlet on the bottom side wall of the roughing box, the inlet and outlet being correspondingly arranged, a collecting component below the outlet, a conveying component in the middle of the inner side wall of the roughing box, a washing component on the top inner side wall of the roughing box, and a first magnetic plate slidably fitted in the middle of the inner side wall of the roughing box. The first magnetic plate is located inside the conveying component, and a first inlet is opened in the middle of the side wall of the first magnetic plate. The coarse selection box is equipped with a second magnetic plate, which is located inside the conveying assembly. A second inlet is formed in the middle of the side wall of the second magnetic plate. A third magnetic plate is slidably fitted in the middle of the inner side wall of the coarse selection box, located between the conveying assembly and the cleaning assembly. A third inlet is formed in the middle of the side wall of the third magnetic plate. A fourth magnetic plate is slidably fitted in the middle of the inner side wall of the coarse selection box, located between the conveying assembly and the collecting assembly. A fourth inlet is formed in the middle of the side wall of the fourth magnetic plate. The discharge port and the fourth inlet are correspondingly arranged. The conveying assembly includes a first coarse selection box, which is fixed inside the coarse selection box. A motor is fixedly connected to the middle of the side wall. A first rotating shaft is fixedly connected to the output end of the motor. A first spiral auger is mounted on the middle of the side wall of the first rotating shaft. The first spiral auger rotates inside the first coarse separator box. A synchronous belt is rotatably connected to the middle of the side wall of the first rotating shaft. A second rotating shaft is rotatably connected to the middle of the inner side wall of the synchronous belt. A second spiral auger is mounted on the middle of the side wall of the second rotating shaft. The second spiral auger and the first spiral auger are arranged with opposite threads. A second coarse separator box is fixed to the middle of the inner side wall of the coarse separator box. The second spiral auger rotates inside the second coarse separator box. The feed inlet, the first coarse separator box, and the second coarse separator box are connected. Connected to the discharge port, this step, through the setting of a first magnetic plate, a second magnetic plate, a third magnetic plate, a fourth magnetic plate, a first coarse separation box, and a second coarse separation box, can effectively remove magnetic impurities from quartz sand by utilizing the magnetic differences of different minerals, thereby improving the purity of quartz sand and the quality of the final product. By setting up a first spiral auger and a second spiral auger, high-purity quartz sand can be continuously and stably conveyed inside the coarse separation box, reducing blockages and interruptions in the material conveying process, thereby improving the overall production efficiency. Moreover, the double-layer design can convey more high-purity quartz sand at the same time, better meeting its conveying and magnetic separation needs, thereby improving screening efficiency.

[0007] In a further technical solution, the material distribution assembly includes a fixing rod fixed to the side wall of the coarse selection box. The fixing rod is located below the inlet. A flow divider plate is rotatably connected to the middle of the side wall of the fixing rod. Multiple guide plates are assembled in the middle of the side wall of the flow divider plate. The multiple guide plates are arranged in an arc shape. This step, by setting the fixing rod, the flow divider plate, and the guide plates, allows high-purity quartz sand to be poured into the first coarse selection box in batches. This ensures that the conveying assembly maintains an appropriate load during each conveying, avoiding overload or no-load operation, thereby improving conveying efficiency. Furthermore, pouring high-purity quartz sand in batches reduces the amount of material conveyed each time, thereby reducing the wear rate of the equipment and extending its service life.

[0008] In a further technical solution, the cleaning assembly includes a water pump, which is fixed to the side wall of the coarse selection tank. A water pump is fixedly connected to the water pump's suction end, and a water storage tank is fixedly connected to the water pump's outlet end. The water storage tank is fixed inside the coarse selection tank, and multiple water outlets are provided in the middle of the side wall of the water storage tank. The cleaning assembly and the conveying assembly are connected. This step, by setting up a water pump, a water pump, a water storage tank, and water outlets, can remove dirt, dust, and other impurities adhering to the surface of the quartz sand, which helps to improve the purity of the quartz sand. Furthermore, cleaning can remove harmful substances from the surface of the quartz sand, such as radioactive elements, microorganisms, and heavy metals, which helps it maintain stable performance during subsequent processing and use.

[0009] In a further technical solution, the collection component includes a collection box located at the bottom of the coarse selection box. A handle is fixed to the middle of the side wall of the collection box. By setting up the collection box and the handle, this step can conveniently collect the quartz sand that has undergone preliminary screening, reduce the scattering or loss of quartz sand in the coarse selection box, thereby improving the mineral processing efficiency. At the same time, the collection box can also serve as a temporary storage container for quartz sand samples, so that the samples are not contaminated or damaged during transportation and storage.

[0010] In a further technical solution, multiple elastic rods are fixed in the middle of the inner sidewall of the feed inlet. The elastic rods are made of elastic material and are located above the diversion plate. In this step, the high-purity quartz sand to be coarsened is poured into the coarsening box from the feed inlet. The high-purity quartz sand will slowly enter the distribution component under the restriction of the multiple elastic rods. At the same time, the high-purity quartz sand can also be prevented from splashing outward during the distribution process of the distribution component.

[0011] In a further technical solution, elastic pads are fitted in the middle of the sidewalls of the first magnetic plate, the second magnetic plate, the third magnetic plate and the fourth magnetic plate. The elastic pads are made of anti-slip material. This step can increase the friction between the first magnetic plate, the second magnetic plate, the third magnetic plate and the fourth magnetic plate and the hand by setting elastic pads, so as to prevent accidental slippage or loss of control due to hand slippage during use.

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

[0013] 1. By setting up a first magnetic plate, a second magnetic plate, a third magnetic plate, a fourth magnetic plate, a first coarsening box, and a second coarsening box, the magnetic differences between different minerals can be utilized to effectively remove magnetic impurities from quartz sand, improving the purity of the quartz sand and the quality of the final product. The first and second spiral augers ensure continuous and stable transport of high-purity quartz sand within the coarsening box, reducing blockages and interruptions during transport, thereby improving overall production efficiency. Furthermore, the double-layer design allows for the simultaneous transport of more high-purity quartz sand, better meeting its transport and magnetic separation requirements, thus improving screening efficiency.

[0014] 2. By setting up a water pump, water pipe, water storage tank and water outlet, the mud, dust and other impurities attached to the surface of the quartz sand can be removed, which helps to improve the purity of the quartz sand. The cleaning can also remove harmful substances on the surface of the quartz sand, such as radioactive elements, microorganisms, heavy metals, etc., which helps it maintain stable performance in subsequent processing and use.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1 to 4As shown, the device includes a coarse selection box 1. The top side wall of the coarse selection box 1 has an inlet 11, below which is a material distribution assembly. The bottom side wall of the coarse selection box 1 has an outlet 12. The inlet 11 and outlet 12 are correspondingly arranged. Below the outlet 12 is a collection assembly. A conveying assembly is located in the middle of the inner side wall of the coarse selection box 1. A washing assembly is located on the top inner side wall of the coarse selection box 1. A first magnetic plate 13 is slidably fitted in the middle of the inner side wall of the coarse selection box 1. The first magnetic plate 13 is located inside the conveying assembly. A first inlet is located in the middle of the side wall of the first magnetic plate 13. A second magnetic plate 14 is slidably fitted in the middle of the wall. The second magnetic plate 14 is located inside the conveying assembly. A second inlet is opened in the middle of the side wall of the second magnetic plate 14. A third magnetic plate 15 is slidably fitted in the middle of the inner side wall of the coarse selection box 1. The third magnetic plate 15 is located between the conveying assembly and the cleaning assembly. A third inlet is opened in the middle of the side wall of the third magnetic plate 15. A fourth magnetic plate 16 is slidably fitted in the middle of the inner side wall of the coarse selection box 1. The fourth magnetic plate 16 is located between the conveying assembly and the collecting assembly. A fourth inlet is opened in the middle of the side wall of the fourth magnetic plate 16. The discharge port 12 and the fourth inlet are correspondingly arranged.

[0024] The working principle of the above technical solution is as follows:

[0025] Workers pour the high-purity quartz sand to be coarsened into the coarsening box 1 through the feed inlet 11. At this time, the high-purity quartz sand is diverted by the distribution component, allowing it to enter the conveying component in batches. The conveying component then transports the high-purity quartz sand. During this process, the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, and the fourth magnetic plate 16 use magnetic properties to adsorb weakly magnetic impurities in the high-purity quartz sand. The preliminarily purified high-purity quartz sand then enters the collection component through the discharge outlet 12, where it is collected by workers and used in the subsequent washing process. After the coarsening of the high-purity quartz sand is completed, workers remove the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, and the fourth magnetic plate 16. 14. The third magnetic plate 15 and the fourth magnetic plate 16 are pulled out. At this time, the weakly magnetic impurity minerals adsorbed on the surface of the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15 and the fourth magnetic plate 16 will fall into the conveying assembly. Then, the outlets left on the side wall of the coarse selection box 1 by the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15 and the fourth magnetic plate 16 are blocked. At this time, the weakly magnetic impurity minerals in the conveying assembly will be conveyed to the outside of the coarse selection box 1. Then, the high-purity quartz sand after magnetic separation is poured back into the coarse selection box 1. At the same time, the conveying assembly and the cleaning assembly are started. At this time, the cleaning assembly will clean the mud, dust and other impurities on the surface of the high-purity quartz sand.

[0026] like Figures 1 to 4As shown, the conveying assembly includes a first coarse selection box 2, which is fixed inside the coarse selection chamber 1. A motor 21 is fixedly connected to the middle of the side wall of the coarse selection chamber 1. A first rotating shaft 22 is fixedly connected to the output end of the motor 21. A first spiral auger 23 is assembled in the middle of the side wall of the first rotating shaft 22. The first spiral auger 23 rotates inside the first coarse selection box 2. A synchronous belt 24 is rotatably connected to the middle of the side wall of the first rotating shaft 22. A second rotating shaft 25 is rotatably connected to the middle of the inner side wall of the synchronous belt 24. A second spiral auger 26 is assembled in the middle of the side wall of the second rotating shaft 25. The second spiral auger 26 and the first spiral auger 23 are arranged with opposite threads. A second coarse selection box 27 is fixed in the middle of the inner side wall of the coarse selection chamber 1. The second spiral auger 26 rotates inside the second coarse selection box 27. The inlet 11, the first coarse selection box 2, the second coarse selection box 27 and the outlet 12 are connected.

[0027] When high-purity quartz sand enters the first coarsening box 2, the operator starts the motor 21. The motor 21 drives the first rotating shaft 22 to rotate, causing the first rotating shaft 22 to drive the first spiral auger 23 and the synchronous belt 24 to rotate. The synchronous belt 24, in turn, drives the second rotating shaft 25 to rotate synchronously. The second rotating shaft 25, in turn, drives the second spiral auger 26 to rotate inside the second coarsening box 27. Because the second spiral auger 26 and the first spiral auger 23 have opposite threads, when the high-purity quartz sand is conveyed by the first spiral auger 23 into the second coarsening box 27, it will continue to be conveyed by the second spiral auger 26 to the outlet 12 and then into the collection assembly. During the conveying process of the high-purity quartz sand by the first spiral auger 23 and the second spiral auger 26, the first magnetic plate 13, the first... The second magnetic plate 14, the third magnetic plate 15, and the fourth magnetic plate 16 adsorb weakly magnetic impurity minerals in the high-purity quartz sand, thus performing preliminary screening of the high-purity quartz sand. This step, by setting up the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, the fourth magnetic plate 16, the first coarsening box 2, and the second coarsening box 27, can effectively remove magnetic impurities in the quartz sand by utilizing the magnetic differences of different minerals, thereby improving the purity of the quartz sand and the quality of the final product. By setting up the first spiral auger 23 and the second spiral auger 26, the high-purity quartz sand can be continuously and stably conveyed inside the coarsening box 1, reducing blockages and interruptions in the material conveying process, thereby improving the overall production efficiency. Moreover, the double-layer design can convey more high-purity quartz sand at the same time, better meeting its conveying and magnetic separation needs, thereby improving screening efficiency.

[0028] like Figure 2 As shown, the material distribution assembly includes a fixing rod 3, which is fixed on the side wall of the coarse separation box 1. The fixing rod 3 is located below the inlet 11. A flow divider 31 is rotatably connected to the middle of the side wall of the fixing rod 3. Multiple guide plates 32 are assembled in the middle of the side wall of the flow divider 31. The multiple guide plates 32 are arranged in an arc shape.

[0029] The worker pours the high-purity quartz sand to be coarsened into the coarsening box 1 through the feed inlet 11. At this time, the high-purity quartz sand will fall onto the surface of the diverting plate 31 and fall into different guide plates 32. The diverting plate 31 will start to rotate under the gravity of the high-purity quartz sand, so that the high-purity quartz sand inside the guide plate 32 is poured into the first coarsening box 2 when the diverting plate 31 rotates. This step, by setting the fixing rod 3, the diverting plate 31 and the guide plate 32, can pour the high-purity quartz sand into the first coarsening box 2 in batches, so that the conveying component can maintain an appropriate load during each conveying, avoiding overload or no-load operation, thereby improving the conveying efficiency. In addition, pouring the high-purity quartz sand in batches can reduce the amount of material conveyed each time, thereby reducing the wear rate of the equipment and extending its service life.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning assembly includes a water pump 4, which is fixed on the side wall of the coarse selection box 1. A water pump pipe 41 is fixedly connected to the water pump 4's water pump end, and a water storage tank 42 is fixedly connected to the water pump 4's water pump outlet end. The water storage tank 42 is fixed inside the coarse selection box 1, and multiple water outlets 43 are opened in the middle of the side wall of the water storage tank 42. The cleaning assembly and the conveying assembly are connected.

[0031] The workers pull out the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, and the fourth magnetic plate 16. Then, they use plugs to seal the outlets left on the side wall of the coarse selection box 1 by the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, and the fourth magnetic plate 16. The high-purity quartz sand after magnetic separation is then poured back into the first coarse selection box 2. The conveying assembly and the water pump 4 are then started. At this time, the water pump 4 will pump water from the water tank into the water storage tank 42 through the water pumping pipe 41, and spray it from multiple water outlets 43 onto the surface of the high-purity quartz sand being conveyed by the conveying assembly. This step, by setting up the water pump 4, the water pumping pipe 41, the water storage tank 42, and the water outlets 43, can remove the mud, dust, and other impurities attached to the surface of the quartz sand, which helps to improve the purity of the quartz sand. In addition, the cleaning can also remove harmful substances on the surface of the quartz sand, such as radioactive elements, microorganisms, heavy metals, etc., which helps it maintain stable performance in subsequent processing and use.

[0032] like Figure 1 and Figure 2 As shown, the collection component includes a collection box 5, which is located at the bottom of the coarse separation box 1, and a handle 51 is fixed to the middle of the side wall of the collection box 5.

[0033] By setting up the collection box 5 and handle 51, the quartz sand that has undergone preliminary screening can be collected conveniently, reducing the scattering or loss of quartz sand in the coarsening box 1, thereby improving the mineral processing efficiency. At the same time, the collection box 5 can also serve as a temporary storage container for quartz sand samples, ensuring that the samples are not contaminated or damaged during transportation and storage.

[0034] like Figure 1 and Figure 2 As shown, multiple elastic rods 6 are fixed in the middle of the inner side wall of the feed inlet 11. The elastic rods 6 are made of elastic material and are located above the diversion plate 31.

[0035] The high-purity quartz sand to be coarsened is poured into the coarsening box 1 through the feed port 11. The high-purity quartz sand will slowly enter the distribution component under the restriction of multiple elastic rods 6. At the same time, the high-purity quartz sand can also be prevented from splashing outwards during the distribution process of the distribution component.

[0036] like Figures 2 to 4 As shown, elastic pads 7 are fitted in the middle of the side walls of the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15 and the fourth magnetic plate 16. The elastic pads 7 are made of anti-slip material.

[0037] By setting the elastic pad 7, the friction between the first magnetic plate 13, the second magnetic plate 14, the third magnetic plate 15, the fourth magnetic plate 16 and the hand can be increased, preventing accidental slippage or loss of control due to hand slippage during use.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
