Description

Technical Field

[0001] The utility model belongs to the technical field of quartz sand production, and specifically relates to a quartz sand pickling device. Background Art

[0002] The surface of quartz sand often absorbs some organic or inorganic impurities, which will have an adverse effect on the subsequent processing process. In order to ensure the purity of quartz sand, it is necessary to pickle the quartz sand. Quartz itself is not soluble in acid, but hydrochloric acid can dissolve iron and some other elements. Through this process, we can effectively separate the impurities in quartz sand. A pickling device is required for pickling quartz sand.

[0003] Chinese patent CN215516658U discloses a quartz sand pickling device, comprising a pickling net barrel, which is rotatably arranged in a pickling cylinder; and a tray, which is conically fixed to the lower end of the pickling net barrel, and the lower end of the tray is fixed to the bottom wall of the pickling cylinder through a first bearing; a transmission rod linked to the output end of a driving device is fixedly connected to the lower end of the tray; the transmission rod is hollow, and the internal cavity of the transmission rod is a first air guide cavity.

[0004] The above-mentioned patent uses an impact nozzle to spray high-pressure gas to move the quartz sand upward. However, when the amount of quartz sand to be pickled is large, its thickness is deep and its own weight is large, and the effect of the impact nozzle to drive the quartz sand to move upward becomes poor, resulting in a decrease in the mixing effect of the quartz sand and the pickling solution, and then the pickling effect is reduced. Therefore, a technical measure is proposed to solve the problem that when the amount of quartz sand to be pickled is large, the effect of the impact nozzle to drive the quartz sand to move upward becomes poor, resulting in a decrease in the mixing effect of the quartz sand and the pickling solution, and then the pickling effect is reduced.

The first connection port 14 and the second connection port 15 are connected through the circulation component 2. A limit ring 13 is provided on the upper surface of the fixed ring 6, and two groups of symmetrically distributed support rods 8 are provided at the lower part of the fixed ring 6. When the quartz sand is actually pickled, the quartz sand is injected into the pickling mesh tube 16 inside the box 1 through the sand inlet pipe 5, and then the pickling liquid (mainly hydrochloric acid) is injected through the liquid inlet pipe 4 to start pickling the quartz sand. When the quartz sand is pickled, the circulation component 2 is started to circulate the pickling liquid. After the pickling is completed, the second valve 12 is opened to facilitate the discharge of the pickling liquid from the liquid outlet pipe 10. The first valve 11 is opened to allow the pickled quartz sand to fall from the inside of the box 1 to complete the collection of the quartz sand.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the circulation component 2 includes an acid-resistant pump 201, which is fixedly mounted on the upper surface of the side plate 7. The acid-resistant pump 201 is connected to a vertical pipe 206, the upper end of which is fixedly passed through the second connecting port 15, and the vertical pipe 206 is connected to a mounting plate 202, which is fixedly fitted with the inside of the box body 1, and a nozzle 207 is installed on the side of the mounting plate 202, and the nozzle 207 is smaller on the side away from the mounting plate 202. The other end of the acid-resistant pump 201 is connected to a hose 205, and the other end of the hose 205 is connected to a connecting pipe 204, which is fixedly passed through the first connecting port 14, and the other end of the connecting pipe 204 is connected to a liquid suction pipe 203, and the liquid suction pipe 203 is at the lower part of the inside of the box body 1. The hose 205 passes through a limiting ring 13, and the limiting ring 13 provides a limiting position for the hose 205 , start the acid-resistant pump 201, and the acid-resistant pump 201 starts to draw the pickling liquid at the bottom of the box body 1 into the suction pipe 203. The pickling liquid entering the suction pipe 203 then enters the connecting pipe 204, and the pickling liquid enters the hose 205 through the connecting pipe 204, and then enters the acid-resistant pump 201. Under the action of the acid-resistant pump 201, the pickling liquid enters the vertical pipe 206, and then the pickling liquid enters the mounting plate 202, and then the pickling liquid enters the nozzle 207, and the nozzle 207 sprays the pickling liquid toward the quartz sand (there are gaps between the quartz sand particles, and when the nozzle 207 sprays the quartz sand, the pickling liquid will pass through the gaps into the interior of the quartz sand). In addition, under the action of the suction pipe 203, the pickling liquid close to one side of the suction pipe 203 is also moving toward the suction pipe 203, thereby realizing the circulation of the pickling liquid.

[0028] Working principle: When the quartz sand is actually pickled, the quartz sand is injected into the pickling net cylinder 16 inside the box 1 through the sand inlet pipe 5, and then the pickling liquid (mainly hydrochloric acid) is injected through the liquid inlet pipe 4 to start pickling the quartz sand;

[0029] When pickling quartz sand, the circulation component 2 is started to circulate the pickling liquid. The specific method is to start the acid-resistant pump 201. The acid-resistant pump 201 is started to draw the pickling liquid at the bottom of the box body 1 into the suction pipe 203. The pickling liquid entering the suction pipe 203 then enters the connecting pipe 204. The pickling liquid enters the hose 205 through the connecting pipe 204 and then enters the acid-resistant pump 201. Under the action of the acid-resistant pump 201, the pickling liquid enters the vertical pipe 206, and then the pickling liquid enters the mounting plate 202, and then the pickling liquid enters the nozzle 207. The nozzle 207 sprays the pickling liquid toward the quartz sand (between the quartz sand particles). There is a gap between the two sides of the quartz sand, and when the nozzle 207 sprays toward the quartz sand, the pickling liquid will enter the quartz sand through the gap). In addition, under the action of the liquid suction pipe 203, the pickling liquid close to the side of the liquid suction pipe 203 also moves toward the liquid suction pipe 203, thereby realizing the circulation of the pickling liquid. Through the setting of the circulation component 2, the pickling liquid is circulated, so that the pickling liquid and the quartz sand are in uniform contact, avoiding that the quartz sand in the middle position is not fully pickled, and when the number of quartz sands is large, it will not affect the mixing effect between the quartz sand and the pickling liquid, thereby ensuring the pickling effect of the quartz sand, and having strong practicality.

[0030] After the pickling is completed, the second valve 12 is opened to facilitate the discharge of the pickling liquid from the liquid outlet pipe 10, and the first valve 11 is opened to allow the pickled quartz sand to fall from the inside of the box 1, thereby completing the collection of the quartz sand.
