Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand production technology, specifically to a sorting device for quartz sand production. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. It is a hard, wear-resistant, and chemically stable silicate mineral, with SiO2 as its main mineral component. It is an important industrial mineral raw material. Quartz sand is milky white or colorless and translucent, with a hardness of 7. It is brittle, has no cleavage, exhibits a conchoidal fracture, and has a greasy luster. Its density is 2.65. Its chemical, thermal, and mechanical properties show significant anisotropy. It is insoluble in acids, slightly soluble in KOH solution, and has a melting point of 1750 degrees Celsius. Industrially, quartz sand is often classified into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. It is widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, and other industries. In the quartz sand production process, sorting is a crucial step.
[0003] However, traditional feeding methods often lead to blockages or accumulation of quartz sand at the feed inlet, especially when the raw material has high moisture content or large particle size. This not only increases operational difficulty but can also cause equipment damage or downtime for maintenance, severely impacting the continuity and stability of production. Secondly, during the sorting process, due to differences in particle size, shape, and density, quartz sand often requires multiple screenings and gradings. However, traditional sorting equipment often lacks effective mixing and unblocking mechanisms, causing quartz sand to easily clog or accumulate in the sorting drawers, resulting in low sorting efficiency and unsatisfactory sorting results.

[0027] 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.
[0028] 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.
[0029] Example 1:
[0030] A preferred embodiment of the quartz sand production sorting equipment provided by this utility model is, for example... Figure 1-4As shown: A sorting device for quartz sand production includes a sorting box 1, a controller 2 on one side of the sorting box 1, a symmetrical connection port 1 on the front of the sorting box 1, a connection port 2 directly below the connection port 1, sliding openings equidistantly on both sides of the sorting box 1, and locking openings on the back of the sorting box 1. A receiving drawer 3 is slidably connected to the front of the sorting box 1 through the connection port 1. A sorting assembly 4 is installed inside the sorting box 1, and a dust collection assembly 5 is installed at the bottom of the sorting box 1. The sorting assembly 4 includes: a clearing component 41 installed inside the sorting box 1; a vibration component 42 installed outside the sorting box 1; the clearing component 41 includes: a clearing box 411 connected to the top of the sorting box 1; a feed hopper 412 connected to the top of the clearing box 411; a motor 413 fixedly installed on the front of the clearing box 411; and a connecting frame 416. The connection port 1 is engaged with the sorting box 1; the output end of the motor 413 is provided with a cleaning shaft 414, the other end of the cleaning shaft 414 is movably passed through one side of the outer wall of the cleaning box 411, one side of the inner wall of the cleaning box 411 and extends to the other side of the inner wall of the cleaning box 411, and is rotatably connected to the cleaning box 411 through a bearing. The outer wall of the cleaning shaft 414 is equidistantly equipped with cleaning blades 415. The back of the connecting frame 416 is fixedly installed with a locking block 417, which is engaged with the sorting box 1 through a locking port. The inner walls of the connecting frame 416 are respectively fixedly installed with guide rods 418, and the top and bottom ends of the guide rods 418 are respectively fixedly installed with limit plates 419. The outer wall of the guide rods 418 is slidably connected with a sorting drawer 4111. The outer side of the connecting frame 416 is fixedly installed with a handle 4112. The bottom of the two sorting drawers 4111 are respectively provided with a sorting hole 1 and a sorting hole 2.
[0031] Furthermore, in this embodiment, the quartz sand raw material is poured into the unclogging box 411 through the feed hopper 412. The feed hopper 412 provides a channel for the quartz sand to enter the unclogging box 411, ensuring that the raw material can smoothly enter the first process of the sorting equipment. The motor 413 is started, and the output end of the motor 413 drives the unclogging shaft 414 to rotate. The unclogging blades 415, which are equidistantly installed on the unclogging shaft 414, rotate with the rotation of the unclogging shaft 414, stirring and unclogging the quartz sand entering the unclogging box 411, preventing the quartz sand from clogging or accumulating during the feeding process. The unclogging quartz sand falls into the sorting drawer 4111 in the connecting frame 416. The connecting frame 416 is connected to the sorting box 1 through the connecting port 1 to ensure the stability of the connection. The back of the connecting frame 416 The locking block 417 on the surface is further locked into the sorting box 1 through the locking port, which increases the overall structural strength. The sorting drawer 4111 can only slide vertically under the restriction of the guide rod 418. The limiting plates 419 at the top and bottom of the guide rod 418 prevent the sorting drawer 4111 from disengaging from the guide rod 418. The sorting holes 1 and 2 at the bottom of the two sorting drawers 4111 have different hole diameters. The initial sorting is carried out according to the particle size of the quartz sand. The smaller particles of quartz sand fall into the space below through the sorting hole 2, while the larger particles of quartz sand remain in the upper sorting drawer 4111. The handle 1 4112 on the outside of the connecting frame 416 makes it convenient for the operator to pull the connecting frame 416 and the sorting drawer 4111 out of the sorting box 1 for cleaning or inspection.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the quartz sand production sorting equipment provided by this utility model is as follows: Figure 1-4As shown: The vibration component 42 includes: a dual-axis motor 421, fixedly installed on the back of the sorting box 1; a short shaft 424, symmetrically and movably installed on both sides of the sorting box 1; and a limiting rod 428, symmetrically and fixedly installed on both sides of the sliding opening. The output end of the dual-axis motor 421 is provided with a long shaft 422, and the other end of the long shaft 422 is fixedly fitted with a pulley 423. The short shaft 424 is rotatably connected to the sorting box 1 via a bearing. A second pulley 425 and a protrusion 426 are fixedly fitted onto the outer wall of the short shaft 424, respectively. The protrusion 426 is located inside the second pulley 425. The second pulley 425 is connected to the first pulley via a belt 427. 423 is a transmission connection. A slider 429 is slidably connected inside the limiting rod 428. A connecting plate 4211 is fixedly installed between the sliders 429. The surface of the connecting plate 4211 has a movable opening. The connecting plate 4211 is movably sleeved on the outside of the short shaft 424 through the movable opening. A movable plate 4214 is fixedly installed on the outside of the connecting plate 4211. A fixed horizontal plate 4212 is symmetrically fixedly installed on the opposite side of the connecting plate 4211. The other end of the fixed horizontal plate 4212 movably passes through the sliding opening and is slidably connected to the sorting box 1 through the sliding opening. A T-shaped push plate 4213 is fixedly installed on the top of the fixed horizontal plate 4212.
[0034] Furthermore, in this embodiment, by activating the dual-axis motor 421, the output end of the dual-axis motor 421 drives the long shaft 422 to rotate. A pulley 423, fixedly mounted on the other end of the long shaft 422, rotates along with the long shaft 422. The pulley 423 transmits power to the pulley 425 via a belt 427. The pulley 425 drives the short shaft 424 to rotate. The protrusion 426 on the inner side of the pulley 425 rotates along with the short shaft 424. As the protrusion 426 on the short shaft 424 rotates, it continuously impacts the movable plate 4214. Due to the sliding contact on both sides of the connecting plate 4211... Block 429 slides inside the limiting rod 428, restricting the movement direction of the connecting plate 4211. Therefore, the movable plate 4214 can only move the connecting plate 4211 in the horizontal direction. The fixed horizontal plate 4212, which is symmetrically fixed on the opposite side of the connecting plate 4211, also vibrates. Under the action of vibration, the T-shaped push plate 4213 at the top of the fixed horizontal plate 4212 pushes the quartz sand in the sorting drawer 4111, causing the quartz sand to shake and jump continuously in the sorting drawer 4111, accelerating the sorting process of the quartz sand and preventing the quartz sand from clogging the sorting holes one and two.
[0035] Example 3:
[0036] Based on Embodiments 1 and 2, a preferred embodiment of the quartz sand production sorting equipment provided by this utility model is as follows: Figure 1-4As shown: The dust collection assembly 5 includes: a connecting box 511, which is connected to the bottom of the sorting box 1; an exhaust pipe 518, which is connected to the bottom of the connecting box 511; the front of the connecting box 511 has an installation port, and slide rods 512 are fixedly installed on both sides of the inner wall of the connecting box 511. The outer wall of the slide rods 512 is slidably connected to a locking rod 513. The locking rods 513 have locking grooves equidistantly opened on opposite sides. The locking rods 513 are locked and connected to a filter plate 514 and a fine filter plate 515 through the locking grooves. The fine filter plate 515 is located at the bottom of the filter plate 514. A locking plate 516 is fixedly installed on the outer side of the locking rods 513. The locking plate 516 is locked and connected to the connecting box 511 through the installation port. A handle 517 is fixedly installed on the outer side of the locking plate 516. A fan 519 is installed inside the exhaust pipe 518.
[0037] Furthermore, in this embodiment, the fan 519 is activated to generate suction, which filters the dust in the connecting box 511 through the filter plate 514 and the fine filter plate 515 before discharging it into the external environment, keeping the inside of the sorting equipment clean. The filter plate 514 and the fine filter plate 515 filter the dust that falls into the connecting box 511, preventing dust from entering the air outlet duct 518. The fine filter plate 515 is located at the bottom of the filter plate 514, providing finer filtration of the dust. The handle 517 on the outside of the locking plate 516 allows the operator to pull out the locking rod 513, the filter plate 514, and the fine filter plate 515 from the connecting box 511 for cleaning or replacement.
[0038] In use, the quartz sand raw material is poured into the unclogging box 411 through the feed hopper 412. The feed hopper 412 provides a channel for the quartz sand to enter the unclogging box 411, ensuring that the raw material can smoothly enter the first process of the sorting equipment. The motor 413 is started, and the output end of the motor 413 drives the unclogging shaft 414 to rotate. The unclogging blades 415, which are equidistantly installed on the unclogging shaft 414, rotate with the rotation of the unclogging shaft 414, stirring and unclogging the quartz sand entering the unclogging box 411, preventing the quartz sand from clogging or accumulating during the feeding process. The unclogging quartz sand falls into the sorting drawer 4111 in the connecting frame 416. The connecting frame 416 is connected to the sorting box 1 through the connecting port 1 to ensure the stability of the connection. The locking block 417 on the back of the 6th column further engages with the sorting box 1 through the locking slot, increasing the overall structural rigidity. The sorting drawer 4111, restricted by the guide rod 418, can only slide vertically. The limiting plates 419 at the top and bottom of the guide rod 418 prevent the sorting drawer 4111 from detaching from the guide rod 418. The two sorting drawers 4111 have different diameter sorting holes at their bottoms, allowing for preliminary sorting based on the particle size of the quartz sand. Smaller particles fall through sorting hole 2 into the space below, while larger particles remain in the upper sorting drawer 4111. The handle 4112 on the outside of the connecting frame 416 facilitates the operator pulling the connecting frame 416 and the sorting drawer 4111 out of the sorting box 1. When cleaning or inspection is carried out and sorting is initiated, the dual-axis motor 421 is started. The output end of the dual-axis motor 421 drives the long shaft 422 to rotate. The pulley 423 fixedly sleeved on the other end of the long shaft 422 rotates together with the long shaft 422. The pulley 423 transmits power to the pulley 425 through the belt 427. The pulley 425 drives the short shaft 424 to rotate. The protrusion 426 on the inner side of the pulley 425 rotates together with the short shaft 424. When the protrusion 426 on the short shaft 424 rotates, it continuously hits the movable plate 4214. Because the sliders 429 on both sides of the connecting plate 4211 slide inside the limiting rod 428, the movement direction of the connecting plate 4211 is restricted. Therefore, the movable plate 4214 can only drive the connecting plate 4211 in a certain direction. As the horizontal movement occurs, the fixed horizontal plate 4212, symmetrically fixed on the opposite side of the connecting plate 4211, also vibrates. Under the influence of this vibration, the T-shaped push plate 4213 at the top of the fixed horizontal plate 4212 pushes the quartz sand inside the sorting drawer 4111, causing the quartz sand to continuously shake and jump within the drawer, accelerating the sorting process and preventing quartz sand from clogging sorting holes one and two. The smallest pieces of quartz sand remain inside the receiving drawer 3. The bottom of the receiving drawer 3 has filter holes. When dust is generated during the sorting process, the fan 519 starts, generating suction to filter the dust in the connecting box 511 through the filter plate 514 and the fine filter plate 515, discharging it into the external environment and maintaining the cleanliness of the sorting equipment.Filter plate 514 and fine filter plate 515 filter dust that falls into the connecting box 511, preventing dust from entering the air outlet duct 518. The fine filter plate 515 is located at the bottom of filter plate 514, providing finer filtration. The handle 517 on the outside of the locking plate 516 allows operators to easily pull the locking rod 513, filter plate 514, and fine filter plate 515 out of the connecting box 511 for cleaning or replacement.
[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
