Technical Field

[0001] This utility model relates to the field of tailings processing technology, specifically to a rapid acid washing device for quartz sand. Background Technology

[0002] Quartz sand is a crucial basic raw material in many industrial fields, such as glass manufacturing, semiconductor production, ceramic processing, and precision casting. With the continuous development of modern industrial technology, the quality requirements for quartz sand are increasing. However, natural quartz sand or low-quality quartz sand often contains a variety of harmful impurities such as hematite, mica, and feldspar, which seriously affect the performance and application range of quartz sand.

[0003] Traditional methods for purifying quartz sand mainly involve acid washing, which removes impurities by immersing the quartz sand in an acidic solution and causing a chemical reaction. However, this single acid washing method has many problems. On the one hand, the impurities in quartz sand, such as hematite, mica, and feldspar, are complex in composition. If only acid washing is used, the acid solution needs to react with a large number of impurities, resulting in a large consumption of acid solution. Moreover, the products generated by the reaction between impurities and acid may pollute the acid solution, reducing its effectiveness. This necessitates frequent replacement of the acid solution, increasing production costs and the environmental pressure of treating waste acid.

[0004] To address these issues, we designed a rapid acid washing device for quartz sand. Utility Model Content

[0022] 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.

[0023] Please see Figure 1 , Figure 2 and Figure 5 This utility model provides a technical solution: a rapid acid washing device for quartz sand, including a box body 1, a cavity at the bottom of the box body 1, an air pump 3 fixedly connected inside the cavity, an air inlet pipe 4 on one side of the air pump 3, the air inlet pipe 4 fixedly connected to the outer wall of one side of the box body 1, an air guide pipe 5 fixedly connected to the side of the air pump 3 near the center of the cavity, a stirring shaft 6 sleeved at the top of the air guide pipe 5, the stirring shaft 6 rotatably connected inside the box body 1, a plurality of air jets 7 arranged in a ring on the side of the stirring shaft 6, a flow groove 9 on one side wall of the top of the box body 1, and a flow guide component 8 arranged inside the box body 1 near the flow groove 9.

[0024] In practice, the air pump 3 is turned on to introduce air through the air guide pipe 5. Since the top of the air guide pipe 5 is inserted into the stirring shaft 6 and the stirring shaft 6 is hollow, the air in the air guide pipe 5 will be introduced into the interior of the stirring shaft 6 and then into the slurry through the air jet 7 on the stirring shaft 6. By turning on the reduction motor 13, the reduction motor 13 will drive the second bevel gear 12, the first bevel gear 11 and the stirring shaft 6 to rotate in sequence. The impeller 14 on the stirring shaft 6 will rotate and stir the slurry, which will cause the air to disperse into the slurry and form bubbles. The bubbles will capture mineral particles and rise to the top of the slurry tank. Then, the foam containing minerals will be scraped out of the slurry tank by the flow guide component 8.

[0025] See Figure 3 The flow guiding component 8 includes a circular shaft 801, which is rotatably connected inside the housing 1. A lever 802 is fixedly connected to the surface of the circular shaft 801, and a scraper 803 is fixedly connected to the other end of the lever 802. A drive motor is connected to one end of the circular shaft 801, and the drive motor is fixedly connected to the outer wall of one side of the housing 1. There are four levers 802 and four scrapers 803, and the four levers 802 and four scrapers 803 are evenly distributed on the outer wall of the circular shaft 801.

[0026] In practice, the drive motor will drive the round shaft 801 to rotate, and the rotation of the round shaft 801 will drive the four baffles 802 and scrapers 803 to scrape the foam containing minerals into the flow channel 9.

[0027] See Figure 1 and Figure 2 A waste residue box 10 is fixedly connected to one side of the box body 1. A flow channel 9 passes through the box body 1 and connects the waste residue box 10. A discharge port 16 is fixedly connected to the bottom of the waste residue box 10. A valve is installed on the discharge port 16.

[0028] In practice, the mineral foam scraped into the flow channel 9 enters the waste residue box 10, which can prevent the products generated by the reaction of impurities and acid from contaminating the acid solution and reducing the effectiveness of the acid solution. After the flotation is completed, the feed port 16 can be opened to take out the flotated minerals.

[0029] See Figure 2 A geared motor 13 is fixedly connected to the cavity at the bottom of the housing 1. A second bevel gear 12 is fixedly connected to the output end of the geared motor 13. A first bevel gear 11 is meshed with one end of the second bevel gear 12. An air guide pipe 5 is inserted into the first bevel gear 11. The top end of the first bevel gear 11 is fixedly connected to the stirring shaft 6. Multiple impellers 14 are mounted on the stirring shaft 6. The multiple impellers 14 are evenly arranged on the outer surface of the stirring shaft 6.

[0030] In practice, by turning on the reduction motor 13, the reduction motor 13 drives the second bevel gear 12, the first bevel gear 11 and the stirring shaft 6 to rotate in sequence. The impeller 14 on the stirring shaft 6 rotates and stirs the slurry, causing air to disperse into the slurry to form bubbles. The bubbles will capture mineral particles and rise to the top of the slurry tank.

[0031] See Figure 1 and Figure 4The top of the box 1 is fixedly connected to the feed funnel 2, and the bottom of the box 1 is fixedly connected to the discharge port 17 on one side of the outer wall. The top of the feed funnel 2 is fixedly connected to the crossbar 201, the bottom of the crossbar 201 is fixedly connected to the spring 202, the bottom of the spring 202 is fixedly connected to the slide plate 203, the bottom of the feed funnel 2 is provided with a circular feed port 204, and the slide plate 203 is slidably connected in the circular feed port 204.

[0032] In practice, quartz sand is added to the feed hopper 2. The quartz sand enters the feed hopper 2, which stretches the spring 202 and drives the slide plate 203 to slide down out of the circular feed port 204, so that the quartz sand can enter the box 1 in a measured amount.

[0033] See Figure 1 The top of the box body 1 is fixedly connected to a grouting port 15, and a rubber lining is provided inside the grouting port 15.

[0034] In practice, deionized water is added through grouting port 15 to prepare quartz sand tailings into slurry. Different pH adjusters can also be added through grouting port 15 to adapt to the flotation characteristics of different minerals. The rubber-lined grouting port 15 has excellent stability against chemicals and good acid and oxidation resistance.

[0035] Working principle: Quartz sand is added to the feed hopper 2. The quartz sand entering the feed hopper 2 stretches the spring 202, causing the slide plate 203 to slide downwards out of the circular feed inlet 204. The quartz sand then quantitatively enters the tank 1. Deionized water is added through the grouting port 15 to prepare the quartz sand tailings into a slurry. The deionized water washes away mineral impurities adhering to the surface of the quartz sand. Different pH adjusters are then added sequentially. The air pump 3 is turned on, introducing air through the air pipe 5 into the jet nozzle 7 on the stirring shaft 6 into the slurry. The reduction motor 13 is then turned on, causing it to sequentially drive the second bevel gear 12, the first bevel gear 11, and the stirring shaft 6 to rotate. The impeller 14 on the stirring shaft 6 rotates and agitates the slurry, dispersing air into the slurry to form bubbles. These bubbles capture mineral particles and lift them upwards. The mineral bubbles rise to the top of the slurry tank and are floated by the flow guide assembly 8. The drive motor rotates the circular shaft 801, which in turn drives the baffle plate 802 and scraper 803 to scrape the mineral-containing foam into the flow channel 9. The foam then enters the waste bin 10 from the flow channel 9 to prevent the products generated by the reaction of impurities with acid from contaminating the acid solution and reducing its effectiveness. After the flotation is completed, the feed port 16 can be opened to remove the floated minerals. The purified quartz sand remaining in the tank 1 can be removed by opening the discharge port 17 for recycling. This device introduces reverse flotation technology into the quartz sand purification process. During acid washing, it can effectively remove harmful impurities such as hematite, mica, and feldspar from the quartz sand, thus effectively making up for the shortcomings of traditional acid washing methods.

[0036] It should be noted that pH adjusters of 1 to 7 need to be added during the flotation process. This is to develop a flexible flotation strategy for the unique properties of complex minerals such as hematite, feldspar, and mica. These professional reagents are precisely prepared into solutions of preset concentrations to ensure that the addition amount can be adjusted quickly and accurately during operation. During the quartz sand purification process in tank 1, in order to adapt to the flotation characteristics of different minerals, pH adjusters of different values ​​need to be added through grouting port 15. In addition, based on the buffering effect of sodium silicate aqueous solution, sodium silicate can be used as an inhibitor to suppress the flotation of non-target minerals. Pine oil is added as a foaming agent by titration to ensure the stability and quality of the foam.
