Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quartz sand filter material production, in particular to a kind of impurity removal equipment for quartz sand filter material production. BACKGROUND

[0002] Quartz sand filter material is a kind of granular filter material made of natural quartz ore as raw material, through crushing, screening, washing and other processes, its main component is silicon dioxide (SiO2), with strong chemical stability, high mechanical strength, high hardness, reasonable porosity, acid and alkali corrosion resistance and other excellent properties, widely used in water treatment, environmental protection, chemical industry, electric power, metallurgy and other fields. In the field of water treatment, quartz sand filter material is the core filter medium in water treatment and wastewater treatment system, which can be used to remove suspended solids, colloidal particles, silt, algae and other impurities in water to ensure that the effluent water quality meets the standard; In the chemical industry, it is often used as catalyst carrier, adsorbent filler, etc.; In the electric power industry, it can be used as a filter material for boiler water pretreatment to prevent pipe and equipment from scaling and clogging.

[0003] The quality of quartz sand filter material directly determines the running efficiency and filtering effect of the filtering system, and the impurity content is a key indicator to measure its quality, especially the iron oxide impurities (such as Fe2O3, Fe3O4, etc.), which have a significant impact on the filtered liquid. On the one hand, iron oxide impurities will cause the quartz sand filter material itself to turn yellow, the appearance quality to decrease, and the market competitiveness of the filter material product to be affected; on the other hand, in the filtering process, iron oxide impurities are easy to react with other ions in water to generate soluble iron salts or insoluble iron oxides, which not only adhere to the surface of the filter material to block the pores, reduce the filter flux and adsorption capacity of the filter material, and cause the filtering efficiency to decrease significantly and the backwashing frequency to increase, but also cause the filtered water to appear "yellowing" phenomenon, affecting the sensory indicators of water quality, and if used for drinking water treatment, it may even pose potential risks to human health; In addition, the presence of iron oxide impurities also reduces the chemical stability of quartz sand filter material, and when in contact with corrosive water for a long time, it may accelerate the wear of the filter material, shorten its service life, and increase the operation and maintenance cost of the filtering system.

[0004] In order to remove the iron oxide impurities in the quartz sand filter material, the existing technology mainly uses a magnetic separation device, and the existing quartz sand magnetic separation device mainly uses a fixed magnet combined with a conveying belt or a single rotating drum structure. When working, the quartz sand is in a continuous stacked state through the magnetic field area, and the following significant defects exist: first, the quartz sand falls at a high speed, and the contact time with the magnetic field is short. The small iron filings wrapped inside the quartz sand particles or mixed in the gap of the material are difficult to be fully adsorbed, resulting in incomplete iron removal, and the iron content of the finished quartz sand often exceeds the industrial standard; second, the magnetic separation mechanism lacks effective stirring and dispersion structure. After the iron filings are adsorbed on the surface of the magnet, an "iron filings layer" is easily formed, which wraps part of the quartz sand, causing waste of the quartz sand filter material and reducing the subsequent iron filings adsorption efficiency. Further screening work is required when the iron filings are recovered. These problems seriously restrict the purity and efficiency of the quartz sand filter material impurity removal, and it is difficult to meet the demand for high-purity quartz sand filter material in high-precision industrial fields.

[0015] Compared with the prior art, the present application has the following beneficial effects: through the optimization of the structure design of the whole process of distributing, magnetic separation, stirring and discharging, the present application realizes the high efficiency and precision of impurity removal of quartz sand filter material; compared with the existing device, the present application prolongs the effective contact time of quartz sand and magnetic field, fully exposes and adsorbs iron scraps through multi-directional stirring, greatly improves the thoroughness of iron removal, and specifically:

[0016] 1. The magnetic separation mechanism adopts a design of "inverted conical rotating drum + fixed protective cover + multiple sets of pushing mechanism". The inverted conical rotating drum and the inner wall deceleration ring extend the falling time of the quartz sand. With the umbrella cover rotating and throwing the material, the material can fully contact the magnetic field of the electromagnet. The pushing mechanism stirs the quartz sand and the iron filings adsorbed by the protective cover in the rotating drum from multiple directions through the staggered fixed push plate and movable push plate (including periodic flipping structure). The fixed push plate scrapes the iron filings to remove the quartz sand wrapped around it, and the movable push plate flips the quartz sand to expose the iron filings inside, which greatly reduces the iron filings residue rate and solves the core problems of "iron filings wrapping the quartz sand" and "incomplete iron removal" in traditional devices.

[0017] 2. The bottom of the protective cover narrows and fits with the ring cover to prevent the quartz sand and iron filings from mixing before separation. The inner scraper precisely scrapes off the iron filings on the protective cover and guides them to the discharge platform through the feeding chute. The discharge platform adopts an inclined receiving plate and a drive shaft linkage impact rod design. The vibration effect prevents the iron filings from accumulating and clogging, while smoothly conveying the iron filings to the fixed trough plate. The outer scraper works with the discharge port of the rotary drum to accurately throw the quartz sand into the discharge chute under the action of centrifugal force. The anti-overflow plate prevents material splashing and eliminates the problem of secondary mixing after separation in traditional devices, ensuring the purity of the finished product.

[0018] 3. A single motor drives the drive shaft (which drives the canopy) and the rotating drum synchronously through gear and bevel gear transmission, ensuring that the two operate in coordination according to the set transmission ratio. This eliminates the need for separate control of multiple motors, reducing equipment energy consumption and maintenance costs. At the same time, the drive shaft drives the impact rod to vibrate the discharge table, reducing additional power components, simplifying the equipment structure, improving ease of operation, and solving the problems of poor coordination and high energy consumption of multiple power sources in traditional devices.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below in combination with the accompanying drawings.

[0035] In combination with the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , and the accompanying drawings Figure 3To solve the above technical problems, the technical scheme provided by the present application is as follows: a quartz sand filter material production impurity removal equipment, which comprises a frame body 1, the frame body 1 is provided with a feeding conveyor belt 2, a distributing mechanism 3 and a plurality of magnetic separation mechanisms 5, the distributing mechanism 3 distributes and conveys the quartz sand into the magnetic separation mechanisms 5, an electromagnet 89 is arranged in the magnetic separation mechanism 5, a rotatable rotating drum 6 and a canopy 75 are further arranged in the magnetic separation mechanism 5, the bottom of the canopy 75 is provided with a protective cover 74, the electromagnet 89 is arranged on the inner side of the protective cover 74, the quartz sand is thrown to the inner wall of the rotating drum 6 after passing through the canopy 75, the falling speed of the quartz sand is slowed down due to the centrifugal force, and the iron scraps are adsorbed on the protective cover 74, a plurality of pushing mechanisms 9 are arranged between the rotating drum 6 and the protective cover 74, the quartz sand and the iron scraps on the rotating drum 6 and the protective cover 74 are stirred through the pushing mechanisms 9, the iron scraps in the quartz sand on the rotating drum 6 are exposed and adsorbed on the protective cover 74, the quartz sand in the iron scraps on the protective cover 74 is exposed and falls or is thrown onto the rotating drum 6, and the rotating drum 6 and the protective cover 74 are both provided with scraping structures, so that the separated quartz sand and iron scraps are sent into a discharging structure.

[0036] To solve the problem that the iron impurities in the quartz sand filter material are difficult to be completely removed, especially the iron scraps are easily wrapped or mixed with the quartz sand, causing incomplete separation, the quartz sand impurity removal device of the present application realizes efficient iron removal through optimized structure design, and the working principle is as follows: the quartz sand filter material is conveyed to the distributing mechanism 3 by the feeding conveyor belt 2, is uniformly distributed into a plurality of magnetic separation mechanisms 5 after being distributed by the distributing mechanism 3, and is thrown to the inner wall of the rotating drum 6 under the rotating action of the canopy 75 after entering the magnetic separation mechanism 5, the falling speed of the quartz sand is slowed down due to the centrifugal force, so that the iron scraps in the quartz sand have enough time to be adsorbed by the magnetic force generated by the electromagnet 89 on the inner side of the protective cover 74, at this time, the iron scraps in the quartz sand are adsorbed on the protective cover 74 under the action of the magnetic force, and the plurality of pushing mechanisms 9 between the rotating drum 6 and the protective cover 74 continuously stir, which can on the one hand turn over the quartz sand on the rotating drum 6, so that the iron scraps wrapped therein are exposed, and on the other hand stir the iron scraps adsorbed on the protective cover 74, so that the quartz sand mixed with the iron scraps is separated, and the separated quartz sand falls under the action of gravity or is thrown to the drum wall by the rotating drum 6 to continue the separation process, finally, the pure quartz sand and the adsorbed iron scraps are scraped off by the scraping structures at the bottom of the rotating drum 6 and the protective cover 74 respectively, and are sent into the corresponding discharging structure, so that the iron removal and magnetic separation process of the quartz sand is completed.

[0037] The drawings are combined Figure 3 and the drawings are combined Figure 7As shown, the magnetic separation mechanism 5 includes an upper housing 51 and a base 52. The rotating drum 6 is rotatably disposed inside the upper housing 51. The bottom of the base 52 is provided with a drive mechanism 7, which includes a motor 71, a drive shaft 72 and a transmission shaft 76. The motor 71 drives the drive shaft 72 to rotate at the axis of the base 52. The top of the drive shaft 72 is connected to the umbrella cover 75. The drive shaft 72 drives the rotating drum 6 to rotate through the transmission shaft 76. The base 52 is provided with a fixed platform 8, and an electromagnet 89 is installed on the fixed platform 8.

[0038] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 7 and attached Figure 8 As shown, the motor 71 is fixed on the frame 1. The output end of the motor 71 is provided with a gear 711. The bottom of the drive shaft 72 is provided with a gear 721 that meshes with the gear 711. The transmission shaft 76 is rotatably mounted on the bottom of the fixed platform 8. The two ends are respectively provided with a bevel gear 761 and a bevel gear 762. The drive shaft 72 is provided with a bevel gear 73 that meshes with the bevel gear 761. The bottom of the rotating drum 6 is provided with a bevel gear 61 that meshes with the bevel gear 762.

[0039] To address the issue that the components in the magnetic separation mechanism 5 need to operate in coordination to ensure uniform dispersion and sufficient magnetic separation of quartz sand, the drive mechanism 7 of this invention achieves precise linkage between the rotating drum 6 and the umbrella cover 75 through gear transmission.

[0040] Its working principle is as follows: After the motor 71 fixed on the frame 1 is started, the output end drives the gear 1 711 to rotate. Since the gear 1 711 meshes with the gear 2 721 at the bottom of the drive shaft 72, the rotation of the gear 1 711 will drive the gear 2 721 and the drive shaft 72 connected to it to rotate at the axis of the base 52. The top of the drive shaft 72 is directly connected to the umbrella cover 75. Therefore, the umbrella cover 75 rotates synchronously with the drive shaft 72 to achieve the guidance and dispersion of quartz sand. At the same time, the bevel tooth 2 73 on the drive shaft 72 meshes with the bevel tooth 3 761 at one end of the transmission shaft 76. The rotation of the drive shaft 72 will drive the transmission shaft 76 to rotate. The bevel tooth 4 762 at the other end of the transmission shaft 76 meshes with the bevel tooth 1 61 at the bottom of the rotating drum 6, thereby transmitting power to the rotating drum 6 and causing the rotating drum 6 to rotate inside the upper shell 51.

[0041] Through this series of gear and bevel gear meshing transmission, the power of motor 71 is transmitted to drive shaft 72 (driving umbrella 75) and rotating drum 6 respectively, ensuring that umbrella 75 and rotating drum 6 rotate in coordination according to the set transmission ratio and in the same direction, providing stable power support for the dispersion, conveying and subsequent iron filings separation of quartz sand in magnetic separation mechanism 5, and ensuring that the magnetic separation process is carried out efficiently.

[0042] Combined with appendix Figure 3 and attached Figure 5As shown, the plurality of groups of pushing mechanisms 9 are evenly installed on the fixed table 8, the pushing mechanism 9 comprises a fixed push plate 92 matched with the shield 74 and a movable push plate 93 matched with the inner wall of the rotating drum 6, the fixed table 8 is provided with an inner scraper 82 and an outer scraper 86, the inner scraper 82 and the outer scraper 86 respectively scrape the materials on the shield 74 and the rotating drum 6 to enter the discharge table 521 on the inner side of the base 52 and the discharge groove 53 on the outer side of the upper shell 51.

[0043] In combination with the accompanying drawings Figure 5 and the accompanying drawings Figure 12 As shown, the pushing mechanism 9 further comprises a stand 91 fixed on the fixed table 8, a plurality of fixed push plates 92 are fixed on the stand 91 in a row, and a plurality of movable push plates 93 are rotatably arranged on the stand 91 in a row, the fixed push plates 92 and the movable push plates 93 of the plurality of groups of pushing mechanisms 9 are arranged in a staggered manner, and the inclination directions of the fixed push plates 92 and the movable push plates 93 of one group of pushing mechanisms 9 are opposite to the inclination directions of the fixed push plates 92 and the movable push plates 93 of the remaining pushing mechanisms 9.

[0044] In order to solve the problem that the separation of quartz sand and iron filings is not complete in the magnetic separation process, and the iron filings are easily wrapped by the quartz sand or the quartz sand is easily mixed in the iron filings, the pushing mechanism 9 of the present application realizes the full tumbling and separation of the materials through the cooperation of the fixed push plate 92 and the movable push plate 93.

[0045] The working principle is as follows: the plurality of groups of pushing mechanisms 9 are evenly installed on the fixed table 8, the stand 91 of each group of pushing mechanisms 9 is fixed on the fixed table 8, the fixed push plates 92 in a row are fixed on the stand 91 and matched with the shield 74, the movable push plates 93 in a row are rotatably arranged on the stand 91 and matched with the inner wall of the rotating drum 6, and the fixed push plates 92 and the movable push plates 93 of the plurality of groups of pushing mechanisms 9 are arranged in a staggered manner, and the inclination directions of the push plates of one group are opposite to those of the remaining groups.

[0046] When the rotating drum 6 rotates, the movable push plate 93 rotates in a specific area, so that the inclination angle of the movable push plate 93 is turned over by 90°, a reverse inclination effect is generated, through the staggered arrangement and the reverse inclination structure design, the quartz sand on the rotating drum 6 is stirred in multiple directions and multiple angles, which facilitates the exposure of the iron filings in the quartz sand; the fixed push plate 92 can scrape the iron filings adsorbed on the shield 74, through the staggered arrangement and the reverse inclination structure design, the iron filings adsorbed on the shield 74 are moved downward under the pushing of the plurality of fixed push plates 92, one of the fixed push plates 92 pushes upward, and overall the iron filings are in the process of moving downward, under the stirring of the fixed push plate 92, the quartz sand mixed in the iron filings falls off, the overall downward pushing effect of the fixed push plate 92 on the iron filings facilitates the separation of the iron filings from the shield 74.

[0047] In order to improve the iron scrap separation effect and facilitate the quartz sand discharge, the inner scraper 82 and the outer scraper 86 on the fixed table 8 respectively scrape the iron scrap and the quartz sand on the protective cover 74 and the rotating drum 6 after being fully separated, the iron scrap is pushed to the working interval of the inner scraper 82 under the pushing of the fixed push plate 92, the iron scrap is further separated from the magnetic field through the inner scraper 82, and the iron scrap falls into the discharge table 521 on the inner side of the base 52; when the quartz sand slowly falls along with the rotating drum 6, the quartz sand moves upward after colliding with the inclined outer scraper 86, so that the quartz sand is prevented from gathering on the rotating drum 6, and then the quartz sand enters the discharge groove 53 on the outer side of the upper shell 51; through the stirring effect of the pushing mechanism 9 on the rotating material, the thoroughness and efficiency of the magnetic separation are further improved.

[0048] Combining with the drawings Figure 13 and the drawings Figure 14 As shown in the drawings, the lever 96 is hinged on the column 91, the gear three 94 and the gear four 97 are respectively arranged on the end portions of the movable push plate 93 and the lever 96 extending into the inner cavity of the column 91, the rack 95 is slidably arranged in the inner cavity of the column 91 and meshes with the gear three 94 and the gear four 97, the torsional spring 98 is arranged on the lever 96 and connected with the column 91, and the arc-shaped plate 65 is arranged on the inner side of the rotating drum 6 and cooperates with the lever 96.

[0049] In order to solve the uncontrollable problem of the rotating range and rotating time of the movable push plate 93, the movable push plate 93 generates a compound motion through the cooperation of the arc-shaped plate 65 and the lever 96 to enhance the separation effect, and the working principle is as follows: the lever 96 on the column 91 meshes with the rack 95 in the inner cavity of the column 91 through the gear four 97 and the gear three 94 respectively, the lever 96 is further connected with the column 91 through the torsional spring 98, and the arc-shaped plate 65 on the inner side of the rotating drum 6 periodically pushes the lever 96 to swing when the arc-shaped plate 65 rotates along with the rotating drum 6, the lever 96 swings to drive the gear four 97 to rotate, the gear three 94 is synchronously rotated through the meshing transmission of the rack 95, and then the movable push plate 93 is driven to rotate, when the arc-shaped plate 65 is separated from the lever 96, the elastic force of the torsional spring 98 resets the lever 96, and the gear four 97 reversely rotates in the resetting process, the gear three 94 and the movable push plate 93 are reversely swung through the transmission of the rack 95.

[0050] Through this process, the movable push plate 93 will periodically swing under the synergistic action of the lever 96, the gear and the rack 95 and the torsional spring 98, thereby generating an angle flipping effect, so that the quartz sand on the rotating drum 6 is generally pushed upward by the movable push plate 93 under the guidance of the movable push plate 93 and is pushed downward at a specific position, the dislocation setting and the reverse inclined structure of the fixed push plate 92 are matched, the stirring intensity and the angle change of the material between the rotating drum 6 and the protective cover 74 are further enhanced, and the separation of the quartz sand and the iron scrap is more thorough.

[0051] Combining with the drawings Figure 3 and the drawings Figure 6As shown, the radius of the upper part of the inner wall of the rotating drum 6 is larger than the radius of the lower part of the inner wall, forming an inverted conical cavity. Multiple deceleration rings 63 are provided on the inner wall of the rotating drum 6. The deceleration rings 63 are slightly protruding on the inner wall of the rotating drum 6. The movable push plate 93 is offset from the deceleration rings 63. The rotating drum 6 is provided with a discharge port 64. The outer scraper 86 is provided at the discharge trough 53. When the discharge port 64 rotates to the discharge trough 53, the material blocked by the outer scraper 86 is thrown into the discharge trough 53 through the discharge port 64.

[0052] Combined with appendix Figure 6 Appendix Figure 9 and attached Figure 10 As shown, the top of the fixed platform 8 is an inclined surface, and an annular groove 84 is provided on the inclined surface. An annular plate 62 is provided on the inner side of the bottom of the rotating cylinder 6. The annular plate 62 extends into the annular groove 84. A fixed rod 85 is provided on the fixed platform 8. An outer scraper 86 is connected to the fixed rod 85. A scraper 87 that cooperates with the annular plate 62 is provided at the bottom of the outer scraper 86. An anti-overflow plate 88 is provided on the side of the scraper 87 near the protective cover 74.

[0053] To address the issues of insufficient magnetic separation due to excessively fast material descent within the rotating drum 6, and the problems of material leakage and incomplete separation during discharge, this invention optimizes the structure of the rotating drum 6 and the material shoveling assembly to achieve efficient separation and precise discharge. Its working principle is as follows: the upper radius of the inner wall of the rotating drum 6 is larger than the lower radius, forming an inverted conical cavity. Combined with a slightly protruding deceleration ring 63 on the inner wall, when the rotating drum 6 rotates, the quartz sand generally moves downwards along the inner wall under the influence of centrifugal force and gravity. However, due to the inclined support force of the inner wall of the rotating drum 6 on the material and the centrifugal force during material rotation, the falling speed of the quartz sand slows down. The deceleration ring 63 slows down the material's descent speed and promotes its tumbling, extending the contact time with the magnetic field of the electromagnet 89. Simultaneously, the movable push plate 93 and the deceleration ring 63 are staggered to avoid mutual interference while enhancing the agitation effect on the material, making it easier for iron filings to be adsorbed.

[0054] When the material rotates to the lower part with the rotating drum 6, the discharge port 64 on the rotating drum 6 rotates to the discharge trough 53 position. The outer scraper 86 will block the material at this point. Under the action of centrifugal force, the material is thrown into the discharge trough 53 through the discharge port 64 to complete the collection of quartz sand. The inclined surface at the top of the fixed platform 8 facilitates the falling quartz sand to slide towards the rotating drum 6. The inner ring plate 62 at the bottom of the rotating drum 6 extends into the ring groove 84 of the fixed platform 8, so that the material falls smoothly from the inclined surface at the top of the fixed platform 8 onto the rotating ring plate 62. The bottom of the outer scraper 86 connected to the rod 85 is equipped with a shovel 87. When the rotating drum 6 rotates, the shovel 87 cooperates with the ring plate 62 to scrape the material on the ring plate 62 onto the outer scraper 86. Through the material compression, the material gradually moves upward. The anti-overflow plate 88 on the side near the protective cover 74 prevents the scraped material from overflowing towards the protective cover 74. When the discharge port 64 rotates to the discharge trough 53, the material blocked by the outer scraper 86 is thrown or squeezed into the discharge trough 53 through the discharge port 64, realizing the discharge of quartz sand.

[0055] Combined with appendix Figure 3 Appendix Figure 7 Appendix Figure 9 and attached Figure 11 As shown, the bottom of the protective cover 74 is tapered inward, and the bottom of the fixed platform 8 is provided with a ring cover 81 outside the tapered opening of the protective cover 74. The inner scraper 82 is located inside the ring cover 81 and cooperates with the tapered opening at the bottom of the protective cover 74. The bottom of the inner scraper 82 is provided with a feeding trough 83, which is connected to the top cavity of the discharge platform 521.

[0056] Combined with appendix Figure 3 Appendix Figure 7 and attached Figure 11 As shown, the discharge platform 521 is longitudinally slidably disposed in the internal cavity of the base 52. The receiving plate of the discharge platform 521 is inclined, and the bottom is provided with a bumper 522. The drive shaft 72 is provided with a bumper 722 that cooperates with the bumper 522. The frame 1 is provided with a fixed groove plate 54, and the discharge platform 521 is provided with a feeding groove 523 that cooperates with the fixed groove plate 54.

[0057] To address the problem of iron filings adsorbed on the protective cover 74 being difficult to completely remove and prone to clogging during the discharge process, this invention achieves efficient cleaning and smooth conveying of iron filings by optimizing the structure of the inner scraper 82 and the design of the discharge platform 521. The working principle is as follows: Under the push of the fixed push plate 92, the iron filings are gradually pushed to the bottom constriction of the protective cover 74. An inner scraper 82 is set inside the ring cover 81 at the bottom of the fixed platform 8. The inner scraper 82 fits tightly with the bottom constriction of the protective cover 74. When the protective cover 74 rotates, the inner scraper 82 can push the iron filings gathered at the constriction downward, causing them to leave the magnetic field range and fall into the discharge trough 83 at the bottom of the inner scraper 82, and then enter the discharge platform 521 through the discharge trough 83.

[0058] The receiving plate on the discharge platform 521 is inclined to facilitate the sliding of iron filings. When the drive shaft 72 rotates, it drives the impact rod 722 to rotate synchronously. The impact rod 722 periodically hits the impact platform 522 at the bottom of the discharge platform 521, causing the discharge platform 521 to vibrate longitudinally. This prevents iron filings from accumulating and clogging on the receiving plate. At the same time, the vibration causes the iron filings to slide along the inclined receiving plate to the feeding trough 523 and fall onto the fixed trough plate 54. The fixed trough plate 54 smoothly transports the iron filings to the external collection structure. Through the precise scraping of the inner scraper 82 and the synergistic effect of the vibration feeding of the discharge platform 521, the iron filings are thoroughly separated and transported smoothly.

[0059] The inward-contracting structure at the bottom of the protective cover 74 is to prevent the falling quartz sand from mixing with the accumulated iron filings. The ring cover 81 is located at the constricted position of the protective cover 74, and its maximum outer diameter is smaller than the outer diameter of the upper part of the protective cover 74, thus preventing quartz sand from falling into the ring cover 81. The ring cover 81 also prevents the material scooped up by the shovel plate 87 on the ring plate 62 from splashing into the ring cover 81, further improving the separation effect.

[0062] In order to solve the problems of uneven distribution, conveying blockage and unstable feeding amount of quartz sand before entering the magnetic separation mechanism 5, the material distribution mechanism 3 and the conveying mechanism 4 of the application realize uniform and stable feeding of the material through staged processing and controllable conveying.

[0063] The working principle is as follows: the feeding conveyor belt 2 conveys the quartz sand to the feeding box 31 of the material distribution mechanism 3, the quartz sand in the feeding box 31 is distributed to the corresponding buffer boxes 33 through a plurality of distribution pipes 32, the reverse tapered buffer box 33 utilizes gravity to naturally concentrate the quartz sand and reduces the conveying amount through the bottom neck, realizes the preliminary dispersion of the quartz sand to the conveying mechanism 4, in order to avoid the blockage of the quartz sand in the buffer box 33, an agitating rod extending into the bottom outlet of the buffer box 33 can be arranged on the movable plate 43, the agitating rod vibrates with the vibration of the movable plate 43, and the stable discharging effect is realized.
