Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, specifically to a device for extracting quartz powder from quartz tailings. Background Art

[0002] Quartz, as an important industrial mineral raw material, has wide applications in many fields such as glass, ceramics, electronics, and photovoltaics. With the rapid development of industry, the demand for quartz continues to grow. However, the mining and processing of quartz generates a large amount of quartz tailings. These tailings are usually waste products remaining after quartz ore has undergone crushing, grinding, and sorting processes. They still contain a certain amount of quartz particles, but are also mixed with various impurities, such as clay minerals, feldspar, mica, and metal oxides.

[0003] Traditional methods for extracting quartz powder often involve simple processes and outdated equipment. When processing quartz tailings, they fail to effectively separate quartz particles from impurities. For example, some simple screening devices can only remove larger particles, making it difficult to separate impurities of similar size to quartz particles, resulting in low quartz powder extraction rates. Furthermore, the material transport and processing are not smooth enough, easily leading to blockages and material accumulation, which affects overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a device for extracting quartz powder from quartz tailings, 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: an apparatus for extracting quartz powder from quartz tailings, comprising a support frame, a vibrating screening section, and a screen cleaning section. A pulping machine is fixedly installed on the top of the support frame, and an inclined plate box thickener is provided on one side of the pulping machine. The vibrating screening section is located at the bottom of the pulping machine. The screen cleaning section is located inside the screen cleaning section. The pulping machine forms a uniform slurry from the quartz tailings and then transports it to the vibrating screening section, making the material entering the screening box more uniform in particle size and concentration distribution. Compared with directly screening lumpy or uneven tailings, the slurry material can flow better on the screen plate.

[0006] Preferably, the vibrating screening unit specifically includes: a feed pipe connected to the bottom of the pulper; a buffer sleeve disposed at the bottom of the support frame; a screening box disposed at the bottom of the pulper; and a support plate disposed on one side of the support frame.

[0007] Preferably, the top of the screening box is provided with a feed inlet, and the feed pipe is connected to the screening box through the feed inlet. The outer wall of the screening box is provided with a rectangular sliding groove, a screening through-hole and a non-screening through-hole. The buffer sleeve is provided with a buffer spring inside. One end of the buffer spring is fixedly connected to the inner wall of the buffer sleeve, and the other end of the buffer spring is fixedly connected to a sliding rod.

[0008] Preferably, the slide rod is slidably connected to the buffer sleeve, a motor mounting base is fixedly installed on the bottom outer wall of the screening box, a vibration motor is fixedly installed on the motor mounting base, spring connecting blocks are fixedly installed on the top of the support plate and the bottom of the screening box, a support spring is fixedly connected between the spring connecting blocks, a screen plate is fixedly installed inside the screening box, and a vibration motor is provided. The vibration motor is installed on the motor mounting base at the bottom of the screening box. When the vibration motor works, it generates high-frequency vibration and transmits it to the screening box. This vibration causes the quartz tailings slurry entering the screening box to vibrate on the screen plate. Compared with screening in a static state, vibration can prevent particles from accumulating on the screen surface and clogging the screen holes, making it easier for particles to pass through the screen, effectively improving the screening speed and efficiency. For example, when processing tailings containing quartz particles and impurities of various sizes, vibration can allow smaller quartz powder particles to pass through the screen faster and be separated from larger impurity particles.

[0009] Preferably, the screen cleaning unit specifically includes: a slide rail, which is fixedly installed on both outer walls of the screening box; a storage box, which is connected to the outer wall of the screening box; the slide rail is connected to the screening box through a rectangular groove.

[0010] Preferably, a slider is slidably connected inside the slide rail, and a threaded hole is provided on the slider. A motor mounting bracket is fixedly installed on the outer wall of the slide rail, and a motor is fixedly installed inside the motor mounting bracket. A threaded screw is fixedly connected to the output end of the motor. The other end of the threaded screw movably passes through the outer wall of the slide rail and extends into the interior of the slide rail. The other end of the threaded screw is rotatably connected to the inner wall of the slide rail. The motor, the threaded screw, the slider, and other components form a transmission system that enables the automated operation of the screen cleaning unit. During the screening process, the screen may become clogged or have impurities attached, affecting the screening efficiency. This automated system can automatically start the cleaning operation at regular intervals or according to the screen condition, ensuring the continuity of the screening work, improving the efficiency of the entire screening process, and enabling the device to continuously and efficiently screen quartz powder.

[0011] Preferably, the threaded screw is threadedly connected to the slider through a threaded hole, a movable slide plate is fixedly connected between the sliders, the movable slide plate is slidably connected to a rectangular slide groove, a sliding hole is provided on the movable slide plate, a sliding rod is slidably connected inside the sliding hole, a limit plate is fixedly connected to one end of the sliding rod, a cleaning plate is fixedly connected to the other end of the sliding rod, a cleaning brush is fixedly connected to the bottom of the cleaning plate, and a spring is sleeved on the outer wall of the sliding rod.

[0012] Preferably, one end of the spring is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the movable sliding plate. A guide baffle is fixedly installed inside the storage box. An unscreened material cavity is formed between one side of the guide baffle and the inner wall of the storage box, and a screened material cavity is formed between the other side of the guide baffle and the inner wall of the storage box. The storage box has a first feed inlet and a second feed inlet. The screened material cavity is connected to the screening outlet through the second feed inlet, and the unscreened material cavity is connected to the unscreened outlet through the first feed inlet. A conveying pipe is connected inside the screened material cavity, and the screened material cavity is connected to the inclined plate box thickener through the conveying pipe. The guide baffle divides the inside of the storage box into an unscreened material cavity and a screened material cavity. After the screening box performs the screening operation, the quartz powder slurry that has been screened enters the screened material cavity through the screening port, while larger particles and impurities that have not been screened enter the unscreened material cavity through the unscreened port. This clear partitioning allows for precise separation of materials in different states, avoids mixing of screened and unscreened materials, and facilitates the subsequent processing of different materials separately.

[0013] This invention provides a device for extracting quartz powder from quartz tailings. It has the following beneficial effects:

[0014] (1) This utility model uses the power provided by the vibration motor to make the screening box vibrate. This vibration can promote the rapid separation of solid particles and liquid in the quartz tailings slurry. After the slurry processed by the pulping machine enters the screening box, the vibration causes the quartz particles and impurities to quickly separate into layers on the screen plate. The liquid passes through the screen, while the solid particles are distributed at different positions on the screen according to their particle size. Compared with the static filtration method, the vibration greatly speeds up the solid-liquid separation and improves the efficiency of the entire extraction process. It can process more quartz tailings per unit time. By reasonably selecting the aperture of the screen plate, quartz powder particles that meet specific particle size requirements can be accurately screened. The vibration causes the particles to jump and move continuously on the screen. Smaller quartz powder particles can pass through the screen smoothly, while larger impurities are intercepted on the screen. This precise particle size screening ensures the uniformity of the particle size of the quartz powder product and meets the particle size requirements of different application scenarios.

[0015] (2) In the screening process of quartz tailings, fine particles and impurities tend to adhere to the screen surface over time, gradually clogging the screen holes. The screen cleaning unit can promptly remove these deposits, preventing the material throughput from decreasing due to screen clogging. Because the screen can be kept clean, the flow speed of the material on the screen will not slow down due to screen clogging. This allows the device to screen quartz tailings at a relatively stable speed, improving the stability of production efficiency. Attached Figure Description

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1:

[0025] A preferred embodiment of the apparatus for extracting quartz powder from quartz tailings provided by this utility model is, for example... Figure 1-5 As shown: An apparatus for extracting quartz powder from quartz tailings includes a support frame 1, a vibrating screening section 3, and a screen cleaning section 4. A pulper 2 is fixedly installed on the top of the support frame 1, and an inclined plate box thickener 5 is provided on one side of the pulper 2. The vibrating screening section 3 is located at the bottom of the pulper 2. The screen cleaning section 4 is located inside the screen cleaning section 4.

[0026] The vibrating screening unit 3 specifically includes: a feed pipe 311, which is connected to the bottom of the pulper 2; a buffer sleeve 312, which is located at the bottom of the support frame 1; a screening box 3111, which is located at the bottom of the pulper 2; and a support plate 318, which is located on one side of the support frame 1.

[0027] The top of the screening box 3111 is provided with a feed inlet 3113. The feed pipe 311 is connected to the screening box 3111 through the feed inlet 3113. The outer wall of the screening box 3111 is provided with a rectangular slide groove 3112, a sieve passage 3115 and a non-sieve passage 3114. The buffer sleeve 312 is provided with a buffer spring 313 inside. One end of the buffer spring 313 is fixedly connected to the inner wall of the buffer sleeve 312, and the other end of the buffer spring 313 is fixedly connected to a slide rod 314.

[0028] The slide bar 314 is slidably connected to the buffer sleeve 312. A motor mounting base 315 is fixedly installed on the bottom outer wall of the screening box 3111. A vibration motor 316 is fixedly installed on the motor mounting base 315. Spring connecting blocks 319 are fixedly installed on the top of the support plate 318 and the bottom of the screening box 3111. A support spring 317 is fixedly connected between the spring connecting blocks 319. A screen plate 3116 is fixedly installed inside the screening box 3111.

[0029] In this embodiment, the vibration motor 316 on the motor mounting base 315 is started, and the vibration motor generates vibration, which is transmitted to the screening box 3111 through the motor mounting base. The screening box vibrates under the action of the vibration motor, causing the slurry inside the box to jump and roll continuously on the screen plate 3116. Due to the action of the screen plate, quartz powder particles that meet the particle size requirements can pass through the screen plate and flow out from the screening port 3115; while larger impurities cannot pass through the screen and are retained on the screen plate, and are eventually discharged from the non-screening port 3114. During this process, the support spring between the top of the support plate 318 and the spring connecting block 319 at the bottom of the screening box... 317 also plays a supporting and shock-absorbing role, further ensuring the stable vibration of the screening box and improving the screening effect. The vibration greatly accelerates the solid-liquid separation speed and improves the efficiency of the entire extraction process, enabling more quartz tailings to be processed per unit time. By reasonably selecting the aperture of the 3116 screen plate, quartz powder particles that meet specific particle size requirements can be accurately screened out. The vibration causes the particles to jump and move continuously on the screen. Smaller quartz powder particles can pass through the screen smoothly, while larger impurities are intercepted on the screen. This precise particle size screening ensures the uniformity of the quartz powder product and meets the particle size requirements of different application scenarios.

[0030] Example 2:

[0031] Based on Embodiment 1, a preferred embodiment of the apparatus for extracting quartz powder from quartz tailings provided by this utility model is, for example... Figure 1-5 As shown: The screen cleaning unit 4 specifically includes: a slide rail 411, which is fixedly installed on both sides of the outer wall of the screening box 3111; a storage box 4113, which is connected to the outer wall of the screening box 3111; the slide rail 411 is connected to the screening box 3111 through a rectangular slide groove 3112.

[0032] The slide rail 411 has a slider 414 slidably connected inside. The slider 414 has a threaded hole. A motor mounting bracket is fixedly installed on the outer wall of the slide rail 411. A motor 412 is fixedly installed inside the motor mounting bracket. A threaded screw 413 is fixedly connected to the output end of the motor 412. The other end of the threaded screw 413 moves through the outer wall of the slide rail 411 and extends into the interior of the slide rail 411. The other end of the threaded screw 413 is rotatably connected to the inner wall of the slide rail 411.

[0033] The threaded screw 413 is threadedly connected to the slider 414 through a threaded hole. A movable slide plate 415 is fixedly connected between the sliders 414. The movable slide plate 415 is slidably connected to the rectangular slide groove 3112. A sliding hole 416 is provided on the movable slide plate 415. A sliding rod 4111 is slidably connected inside the sliding hole 416. A limit plate 4112 is fixedly connected to one end of the sliding rod 4111. A cleaning plate 417 is fixedly connected to the other end of the sliding rod 4111. A cleaning brush 419 is fixedly connected to the bottom of the cleaning plate 417. A spring 418 is sleeved on the outer wall of the sliding rod 4111.

[0034] One end of spring 418 is fixedly connected to limiting plate 4112, and the other end of spring 418 is fixedly connected to movable sliding plate 415. A guide baffle 4116 is fixedly installed inside the storage bin 4113. A cavity 4117 for unscreened material is formed between one side of the guide baffle 4116 and the inner wall of the storage bin 4113, and a cavity 4118 for screened material is formed between the other side of the guide baffle 4116 and the inner wall of the storage bin 4113. 113 is provided with a first feed inlet 4114 and a second feed inlet 4115. The sieved material cavity 4118 is connected to the sieve passage 3115 through the second feed inlet 4115. The unsieved material cavity 4117 is connected to the unsieved passage 3114 through the first feed inlet 4114. The sieved material cavity 4118 is connected to a conveying pipe 4119. The sieved material cavity 4118 is connected to the inclined plate box thickener 5 through the conveying pipe 4119.

[0035] In this embodiment, the motor 412 on the motor mounting bracket on the outer wall of the slide rail 411 is activated. The motor 412 drives the threaded screw 413 to rotate. The threaded screw 413 is threadedly connected to the threaded hole on the slider 414, causing the slider 414 to move along the axial direction of the threaded screw within the slide rail 411. The movable slide plate 415, which is fixedly connected between the sliders 414, moves together with the slider. Because the movable slide plate 415 is slidably connected to the rectangular slide groove 3112, the movable slide plate can slide smoothly on the outer wall of the screening box 3111. The sliding rod 4111 on the movable slide plate 415 slides within the sliding hole 416. During the movement, the cleaning plate 417 at one end of the sliding rod 4111... The cleaning brush 419 cleans the screen plate 3116. One end of the spring 418 on the outer wall of the sliding rod 4111 is fixedly connected to the limiting plate 4112, and the other end is fixedly connected to the moving slide plate 415. The function of the spring 418 is to ensure that the cleaning brush 419 fits tightly against the surface of the screen plate, adapting to the unevenness of the screen plate and ensuring the removal of impurities adhering to the screen. When encountering protrusions or obstacles on the screen plate, the cleaning plate can adjust its position through the compression and extension of the spring, ensuring smooth cleaning and avoiding a decrease in material throughput due to screen blockage. Because the screen can be kept clean continuously, the flow speed of material on the screen during screening will not slow down due to screen blockage. This allows the device to screen quartz tailings at a relatively stable speed, improving the stability of production efficiency.

[0036] Working principle: Quartz tailings are first fed into pulper 2. Inside the pulper, the quartz tailings are mixed with an appropriate amount of water through stirring and other operations to form a uniform slurry. The slurry provides a suitable material state for subsequent separation and screening processes, allowing quartz particles and impurities to be better dispersed and processed in the liquid medium. The feed pipe 311 at the bottom of pulper 2 conveys the slurry through the feed inlet 3113 to the screening box 3111. When the slurry enters the screening box, the buffer sleeve 312, buffer spring 313, and slide bar 314 at the bottom of the screening box act as buffers. The buffer spring can absorb the impact force generated when the slurry enters, preventing excessive vibration and damage to the screening box, and also helps the slurry to be distributed more stably in the screening box; the vibration motor 316 on the motor mounting base 315 is started, the vibration motor generates vibration, which is transmitted to the screening box 3111 through the motor mounting base. The screening box vibrates under the action of the vibration motor, causing the slurry in the box to jump and roll continuously on the screen plate 3116. Due to the action of the screen plate, the quartz powder particles that meet the particle size requirements can pass through the screen plate and flow out from the screening port 3115;Larger particles of impurities cannot pass through the screen and remain on the screen plate, eventually being discharged through the screen opening 3114. During this process, the support spring 317 between the top of the support plate 318 and the spring connecting block 319 at the bottom of the screening box also plays a supporting and shock-absorbing role, further ensuring the stable vibration of the screening box and improving the screening effect. When the screen needs cleaning, the motor 412 on the motor fixing bracket on the outer wall of the slide rail 411 is started. The motor 412 drives the threaded screw 413 to rotate. The threaded screw 413 is threadedly connected to the threaded hole on the slider 414, causing the slider 414 to move along the axial direction of the threaded screw within the slide rail 411. The movable slide plate 415, fixedly connected between 14, moves together with the slider. Because the movable slide plate 415 is slidably connected to the rectangular slide groove 3112, the movable slide plate can slide smoothly on the outer wall of the screening box 3111. The sliding rod 4111 on the movable slide plate 415 slides in the sliding hole 416. During the movement, the cleaning plate 417 at one end of the sliding rod 4111 has a cleaning brush 419 at its bottom that cleans the screen plate 3116. One end of the spring 418 on the outer wall of the sliding rod 4111 is fixedly connected to the limiting plate 4112, and the other end is fixedly connected to the movable slide plate 415. The function of the spring 418 is to ensure that the cleaning brush 419 can fit tightly against the screen plate. The surface is designed to adapt to the unevenness of the screen plate, ensuring the removal of impurities adhering to the screen. When encountering protrusions or obstacles on the screen plate, the cleaning plate can adjust its position through the compression and extension of springs, ensuring smooth cleaning. The screened material flowing out of the screen plate 3116 through the screening port 3115 enters the screening material cavity 4118 in the storage box 4113. The screening material cavity 4118 is connected to the screening port 3115 through the feed inlet 4115, realizing the smooth collection of materials. The material in the screening material cavity 4118 is then transported to the inclined plate box thickener 5 through the conveying pipe 4119 for further processing, such as concentration and separation. The process prepares the material for subsequent purification steps. Unscreened material that fails to pass through the screen plate flows out from the unscreened outlet 3114 of the screening box 3111 and enters the unscreened material cavity 4117 through the feed inlet 4114 on the storage box 4113 for collection. This unscreened material can be further processed or reprocessed as needed, such as returning it to the pulping machine for further crushing and screening to improve the extraction rate of quartz powder. Through the coordinated work of the above components, the device achieves continuous operation for extracting quartz powder from quartz tailings, including pulping, vibratory screening, screen cleaning, and material classification, collection, and conveying, effectively improving the extraction efficiency and quality of quartz powder.
