Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand processing technology, and in particular to a screening component and production line. Background Technology
[0002] Quartz sand is an important industrial raw material, widely used in glass, ceramics, metallurgy, construction, chemicals, machinery, electronics, rubber, plastics, and coatings. Quartz sand accounts for 60% of the raw materials used in glass production, indicating a huge demand. The particle size distribution of quartz sand directly affects the melting temperature of the furnace, energy consumption, melting quality, and the service life of the glass furnace; therefore, glass processing has strict particle size requirements for quartz sand.
[0003] In related technologies, a drum screen is used to screen quartz sand by particle size. Specifically, the drum screen includes a screen body, which includes a feed section and a discharge section. The initial sand-water mixture formed by the quartz sand and water can enter the screen body through the feed section. Unscreened quartz sand can leave the screen body through the discharge section. However, due to the fluidity of water, it is easy to leak through the screen mesh. Therefore, most of the water will be lost on the feed section side, meaning that the remaining sand-water mixture has poor fluidity on the discharge section side, resulting in poor screening effect on the discharge section side of the screen body. Utility Model Content

[0042] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0043] 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.
[0044] The applicant discovered that quartz sand for glassmaking has extremely strict particle size requirements, as its particle size distribution directly affects the melting temperature, energy consumption, melting quality, and service life of the glass furnace. Specifically, the particle size X requirements for quartz sand for glassmaking are as follows: a) When X is greater than or equal to 25 mesh (0.71 mm), its particle size percentage is 0.0%; b) When X is between 25 mesh and 30 mesh (0.6 mm), its particle size percentage is less than or equal to 0.5%; c) When X is between 30 mesh and 140 mesh, its particle size percentage is greater than or equal to 91.5%; d) When X is less than 140 mesh (0.1 mm), its particle size percentage is less than or equal to 8.0%.
[0045] For example, photovoltaic glass is typically 2mm thick; the silica sand must not contain particles larger than 0.71mm. On one hand, coarser silica sand requires higher temperatures to melt, increasing energy consumption and reducing the lifespan of the glass furnace. On the other hand, particles larger than 0.71mm are difficult to melt and can form stone defects on the glass surface, affecting product quality and damaging the calendering rollers during rolling, resulting in economic losses. Therefore, quartz sand needs to be screened during processing.
[0046] In related technologies, a drum screen is used to screen quartz sand by particle size. Specifically, the drum screen includes a screen body, which includes a feed section and a discharge section. The initial sand-water mixture formed by the quartz sand and water can enter the screen body through the feed section. Unscreened quartz sand can leave the screen body through the discharge section. However, due to the fluidity of water, it is easy to leak through the screen mesh. Therefore, most of the water will be lost on the feed section side, meaning that the remaining sand-water mixture has poor fluidity on the discharge section side, resulting in poor screening effect on the discharge section side of the screen body.
[0047] Therefore, the first aspect of this utility model provides a screening component 10, which is used for screening quartz sand and can ensure the screening effect. See below for details. Figures 1 to 4 The following describes a screening assembly 10 according to an embodiment of this application. Specifically, the screening assembly 10 includes a screen body 100 and a water replenishment section 200.
[0048] Reference Figure 1 and Figure 2 The sieve body 100 is used to screen quartz sand. In some embodiments, the outer contour of the sieve body 100 may be cylindrical. In other embodiments, the outer contour of the sieve body 100 may also be frustum-shaped. This application embodiment is described using a cylindrical sieve body 100 as an example.
[0049] Reference Figure 2 The screen body 100 defines a cavity 110, which can hold quartz sand. The screen body 100 is provided with a feed section 120 and a discharge section 130, both of which are connected to the cavity 110. It should be noted that the feed section 120 is used to feed the sand-water mixture. The discharge section 130 is used to discharge the quartz sand. It can be understood that the target quartz sand in the sand-water mixture can pass through the screen holes of the screen body 100 and exit the screen body 100, while non-target quartz sand can pass through the discharge section 130 and exit the screen body 100, and the particle size of the non-target quartz sand is larger than that of the target quartz sand.
[0050] Reference Figure 1 and Figure 2The water supply section 200 is used to add water to the discharge section 130. The water supply section 200 is connected to the screen body 100. In some embodiments, the water supply section 200 is detachably connected to the screen body 100. In other embodiments, the water supply section 200 may be integrally connected to the screen body 100. The relative arrangement of the water supply section 200 and the screen body 100 may vary depending on the specific circumstances.
[0051] In the technical solution of this utility model, the screening component 10 is used for screening quartz sand. The screening component 10 includes a screen body 100 and a water replenishment part 200. The screen body 100 defines a cavity 110 and a feed part 120 and a discharge part 130 communicating with the cavity 110. The feed part 120 is suitable for feeding a sand-water mixture, and the discharge part 130 is suitable for discharging quartz sand. In related technologies, a drum screen includes a screen body, a feed part, and a discharge part. However, due to the fluidity of water, it is easy to leak through the screen mesh. Therefore, most of the water will be lost on the feed part side, meaning that the remaining sand-water mixture has poor fluidity on the discharge part side, resulting in poor screening effect on the discharge part side of the screen body. The screening component 10 of this solution includes a screen body 100 and a water supply part 200. The water supply part 200 is connected to the screen body 100 and can add water to the discharge part 130, which can effectively increase the water volume on the discharge part 130 side, enhance the fluidity of the sand-water mixture, improve screening efficiency, and ensure screening effect.
[0052] The specific structural configuration of the sieve body 100 is described below. The sieve body 100 extends along the first direction, as shown in the figure. Figure 2 The orientation, specifically the first direction, can be forward or backward. The feed section 120 and the discharge section 130 are located on opposite sides of the screen body 100 along the first direction, allowing the quartz sand to move fully within the cavity 110 for screening. Specifically, the feed section 120 can have a feed inlet, and the discharge section 130 can have a discharge outlet. The structure of the feed section 120 can be the same as that of the discharge section 130.
[0053] The specific dimensions of the sieve body 100 are described below. The extension length of the sieve body 100 along the first direction is L, that is, the extension length of the sieve body 100 is L. Wherein, L satisfies: 0.5m ≤ L ≤ 2m. For example, L can be 0.5m, 0.7m, 0.85m, 1m, 1.2m, 1.3m, 1.5m, 1.9m or 2m, etc. In this embodiment, L is 1.2m as an example for illustration.
[0054] The specific configuration of the water replenishment section 200 is described below. In some embodiments, the screening assembly 10 includes a plurality of water replenishment sections 200. The structures of each water replenishment section 200 may be the same or different. In this embodiment, it is described using the example that all water replenishment sections 200 have the same structure. The water replenishment sections 200 are arranged at intervals along a first direction. It can be understood that the interval between two adjacent water replenishment sections 200 may be a uniform interval or a non-uniform interval. In this embodiment, it is described using the example that the interval between two adjacent water replenishment sections 200 is a uniform interval. Each water replenishment section 200 can add water to the discharge section 130, which can effectively increase the water replenishment amount, enhance the fluidity of the sand-water mixture in the cavity 110, improve screening efficiency, and ensure screening effect.
[0055] It should be noted that in some embodiments, the water replenishment part 200 may be provided on the end side of the screen body 100 opposite to the feed part 120 along the first direction. In other embodiments, the water replenishment part 200 may also be provided on the periphery of the screen body 100. This application embodiment is described using the example of the water replenishment part 200 being provided on both the end side and the periphery of the screen body 100.
[0056] The specific structure of the water replenishment section 200 is described below. In some embodiments, the water replenishment section 200 includes a first sidewall 210 and a second sidewall 220 arranged laterally opposite each other. It is understood that the lateral direction can be parallel to or perpendicular to the first direction. Both the first sidewall 210 and the second sidewall 220 define the water inlet 230. It is understood that the water inlet 230 can be arranged toward the screen body 100. (Refer to...) Figure 3 The first sidewall 210 has a first perpendicular line 211, which is perpendicular to the first sidewall 210. It can be understood that the first perpendicular line 211 can be perpendicular to a portion of the first sidewall 210 or to the entire first sidewall 210. The second sidewall 220 has a second perpendicular line 221, which can be perpendicular to a portion of the second sidewall 220 or to the entire second sidewall 220. The angle formed by the first perpendicular line 211 and the second perpendicular line 221 is θ, meaning the opening angle of the water inlet 230 can be θ. Wherein, θ satisfies: 30° ≤ θ < 180°. For example, θ can be 30°, 45°, 60°, 70°, 90°, 135°, or 150°, etc. Furthermore, the water inlet 230 can be fan-shaped. The water replenishment section 200 of this solution adopts the above-mentioned configuration, which can enhance the uniformity of water replenishment, effectively improve the fluidity of the sand-water mixture in the cavity 110, improve screening efficiency, and ensure screening effect.
[0057] The specific arrangement of the sieve apertures in the sieve body 100 is described below. In some embodiments, the sieve body 100 is provided with a plurality of sieve apertures, which can be arranged at intervals around the sieve body 100, and the opening size of each sieve aperture can be the same. The aperture diameter of the sieve aperture is D, where D satisfies: 0.7mm < D < 0.72mm. For example, D can be 0.71mm. The sieve apertures of this solution can screen out quartz sand with an aperture diameter larger than 0.71mm.
[0058] Reference Figure 4 The second aspect of this application provides a production line 1, which includes the screening component 10, the hydraulic classification component 20, and the hopper 30 described in the above embodiments. It should be noted that the production line 1 can be used to process glass, ceramics, or plastics, etc. This application embodiment uses the processing of glass as an example for illustration.
[0059] The hydraulic classification component 20 is used for particle size classification, achieving the screening of quartz sand. Furthermore, the hydraulic classification component 20 can convey the screened quartz sand (target particle size) to the screening component 10. The hopper 30 is used to collect the quartz sand (non-target particle size) on the screen body 100, and the hopper 30 is configured to return the quartz sand (non-target particle size) to the hydraulic classification component 20. In the prior art, the hydraulic classification component returns the screened quartz sand (non-target particle size) to the grinding component for regrinding, resulting in over-grinding of the quartz sand. In this solution, the hopper 30 can collect the quartz sand and convey it to the hydraulic classification component 20 for re-screening, effectively reducing the formation of fine sand, making product quality more controllable, improving production efficiency, and increasing output.
[0060] In some embodiments, production line 1 includes a feeding unit capable of returning material in hopper 30 to hydraulic classification component 20. Furthermore, a water replenishment unit 200 can add water to hopper 30 to form a sand-water mixture. The feeding unit can then return the sand-water mixture to hydraulic classification component 20. This solution ensures the screening efficiency and effect of quartz sand.
[0061] The specific setup of production line 1 is described below. In some embodiments, production line 1 includes a crushing assembly 40, a grinding assembly 50, and a primary screening assembly 60 connected to each other. The crushing assembly 40 is used to crush quartz sand to form crushed quartz sand. The grinding assembly 50 is used to grind the crushed quartz sand to form ground quartz sand. The primary screening assembly 60 is used to screen the ground quartz sand. Production line 1 of this solution, through crushing, grinding, and primary screening of quartz sand, can achieve accurate particle size classification of quartz sand and ensure the screening effect of quartz sand.
[0062] Reference Figure 4The specific settings of the primary screening component 60 are described below. In some embodiments, the target particle size of the primary screening component 60 is F, which can be 2 mm. When the particle size of the quartz sand is greater than 2 mm, the quartz sand is returned to the grinding component 50 for grinding; when the particle size of the quartz sand is less than 2 mm, the quartz sand is conveyed to the hydraulic classification component 20 for subsequent screening.
[0063] Reference Figure 4 The specific configuration of the hydraulic classification component 20 is described below. In some embodiments, the hydraulic classification component 20 includes a first classification component 201 and a second classification component 202 connected to each other. The structure of the second classification component 202 is different from that of the first classification component 201. The target particle size of the first classification component 201 is G1, where G1 is 1.2 mm. When the particle size of the quartz sand is greater than 1.2 mm, the quartz sand is returned to the grinding component 50 for grinding; when the particle size of the quartz sand is less than 1.2 mm, the quartz sand is conveyed to the second classification component 202. The target particle size of the second classification component 202 is G2, where G2 is 0.1 mm. When the particle size of the quartz sand is greater than 0.1 mm, the quartz sand is conveyed to the screening component 10 for screening; when the particle size of the quartz sand is less than 0.1 mm, the quartz sand is output to the production line 1. The hydraulic classification component 20 of this scheme can reliably classify quartz sand.
[0064] Reference Figure 4 The specific processing procedure of production line 1 according to a specific embodiment of this application is described below. In some embodiments, production line 1 includes a crushing component 40, a grinding component 50, a primary screening component 60, a first grading component 201, a second grading component 202, a screening component 10, and a magnetic suction component.
[0065] The first step is to use the crushing component 40 to crush the original quartz sand to form crushed quartz sand.
[0066] The second step is to use the grinding component 50 to grind the crushed quartz sand to form ground quartz sand.
[0067] The third step involves using the primary screening component 60 to screen the grinding quartz sand, allowing the target quartz sand (particle size less than 2mm) to flow into the first grading component 201 for screening, while the non-target quartz sand (particle size greater than 2mm) is returned to the grinding component 50 for further grinding.
[0068] The fourth step involves using the first grading component 201 to screen the target quartz sand after initial screening, allowing the target quartz sand (particle size less than 1.2 mm) to flow into the second grading component 202 for screening, while the non-target quartz sand (particle size 1.2 mm-2.0 mm) is returned to the grinding component 50 for grinding.
[0069] The fifth step involves using the second grading component 202 to screen the target quartz sand after screening by the first grading component 201, allowing the target quartz sand (particle size greater than 0.1mm) to flow into the screening component 10 for screening, while the non-target quartz sand (particle size less than 0.1mm) is discharged from the production line 1 to form by-product 70.
[0070] Step 6: The target quartz sand (0.1mm-1.2mm particle size) after being screened by the hydraulic classification component 20 is screened using the screening component 10. Water is added to the discharge section 130 of the screen body 100 using the water replenishment section 200 to ensure screening effect and efficiency. The target quartz sand (0.1mm-0.71mm particle size) flows into the magnetic adsorption component for adsorption treatment, resulting in qualified product 80. Non-target quartz sand is conveyed to the hopper 30 for collection. The hopper 30 can return the non-target quartz sand to the hydraulic classification component 20 for screening, which can effectively reduce the formation of fine sand, making product quality more controllable and improving production efficiency.

If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.
