Description

Technical Field

[0002] Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent. Quartz sand is an important industrial mineral raw material and non-chemical hazardous material. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, construction, chemicals, plastics, rubber, abrasives, filter media and other industries.

[0003] In the selection of refined quartz sand and high-purity quartz sand, in order to better improve the quality and yield of quartz sand purification, combined with the characteristics of quartz sand being insoluble in acid and slightly soluble in KOH solution, the acid leaching method is used to remove metal oxides, organic impurities and other non-silicate minerals in quartz sand to improve its purity and chemical stability.

[0004] When quartz sand is acid-leached, it is often placed in the acid solution. The acid solution is in a static state and the quartz sand cannot be turned over.

DETAILED DESCRIPTION

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0067] Example: Figure 1-10 As shown, the present invention provides an acid leaching device for processing refined quartz sand, comprising an acid leaching tank, wherein the acid leaching tank comprises a tank upper base 1, a tank body 2, and a tank lower base 3 arranged in sequence from top to bottom;

[0068] It should be noted that the tank upper seat 1, the tank body 2, and the tank lower seat 3 are fixed together by bolts, and can be disassembled accordingly to facilitate disassembly and maintenance. It should be noted that the inner cylinder 202 of the tank is mounted on the top of the guide cone 304 through a support column.

[0069] The tank body 2 is composed of a vertical outer tank body 201 and an inner tank body 202. The inner tank body 202 is located inside the outer tank body 201, and a circulation loop is formed therebetween that is connected to the inner tank body 202.

[0070] The inner cylinder 202 of the tank is provided with a lower material guide component 5 that guides downward and shakes continuously, and a lifting component 6 that lifts upward continuously is provided between the outer cylinder 201 of the tank and the inner cylinder 202 of the tank;

[0071] The lower seat 3 of the tank body is provided with a vibrating infusion device 7 for conveying acid solution upward from the bottom of the tank body 2, and the vibrating infusion device 7 is connected to the lower material guiding component 5, and can drive the lower material guiding component 5 to vibrate;

[0072] The outer top of the outer cylinder 201 of the tank is provided with a return pipe 4 which is connected to the inner part of the outer cylinder 201 of the tank to output and circulate the acid liquid;

[0073] An exhaust pipe 102 for discharging exhaust gas is provided at the bottom of the tank upper seat 1 and can be communicated with the tank body 2.

[0074] It should be noted that the quartz sand is added into the inner tube 202 of the tank body from the upper seat 1 of the tank body, and then gradually transported downward under the guidance of the rotation of the lower material guide component 5. When it moves to the lowest end, it moves between the outer tube 201 of the tank body and the inner tube 202 of the tank body through the bottom end of the inner tube 202 of the tank body, and then under the action of the rotation of the lifting component 6, the quartz sand can be gradually lifted upward, and fall back to the middle of the inner tube 202 of the tank body through the top of the inner tube 202 of the tank body again. The acid solution is gradually transported from bottom to top, and the direction of the flow of the acid solution is opposite to the moving direction of the quartz sand in the inner tube 202 of the tank body, so that the quartz sand in the inner tube 202 of the tank body can gradually contact with the acid solution with higher concentration that has not reacted, thereby making the reaction effect better and the inner tube 202 of the tank body more stable. The quartz sand can produce a preliminary reaction with the acid solution with lower concentration, and then gradually react with the acid solution with higher concentration, so that the reaction effect is better. In addition, with the cooperation of the lifting component 6, the quartz sand of the same batch will not accumulate, and it is always in a relatively fluid state for reaction, thereby making the contact surface between the quartz sand and the acid solution more sufficient. The upward-flowing acid solution can flow out from the return liquid pipe 4 and be recycled, and the gas generated by the reaction with the acid solution is discharged from the exhaust pipe 102. Under the action of the continuously shaking lower material guide component 5, the quartz sand passing through the lower material guide component 5 can be shaken, and then the reaction gas can be effectively reduced from adhering to the surface of the quartz sand, thereby making the acid leaching effect of the quartz sand better.

[0075] Furthermore, a material guide cone 304 is provided at the center of the top of the tank lower seat 3 and is located directly below the tank inner tube 202. A discharge chamber 311, a liquid storage chamber 312 and an installation chamber 313 are provided in the tank lower seat 3.

[0076] The liquid storage chamber 312 is located below the discharge chamber 311 , and the installation chamber 313 is located inside the discharge chamber 311 and the liquid storage chamber 312 , and the installation chamber 313 is located below the material guide cone 304 ;

[0077] The vibrating infusion device 7 is in the liquid storage chamber 312 to pump liquid;

[0078] The top of the discharge chamber 311 is provided with a circle of openings between the outer side of the material guide cone 304 and the inner wall of the outer cylinder 201 of the tank;

[0079] The bottom of the lifting assembly 6 can be closed, and a driving device that can lift the lifting assembly 6 is installed in the tank upper seat 1;

[0080] The liquid return pipe 4 is connected to the liquid storage chamber 312 , and a liquid injection device for injecting acid into the liquid storage chamber 312 is installed in the installation chamber 313 .

[0081] It should be noted that the acid liquid refluxed in the liquid return pipe 4 flows into the liquid storage chamber 312 and is stored therein. At this time, the liquid injection device (not shown in the figure) can inject the acid liquid into the liquid storage chamber 312 to ensure the concentration of the acid liquid, thereby keeping the concentration of the acid liquid at a relatively high state, thereby achieving a better reaction effect.

[0082] It should also be noted that during the normal reaction process, the bottom opening of the lifting component 6 is closed. When the quartz sand is discharged after the acid leaching is completed, the lifting component 6 is lifted by the driving device, and the opening is opened at this time, so that the quartz sand in the inner cylinder 202 of the tank body can enter the discharge chamber 311 through the opening and then be discharged. When discharging, the liquid exchange outlet pipe 303 is opened to release the acid in the liquid storage chamber 312. When acid leaching is completed again, the acid is injected again through the liquid exchange inlet pipe 302.

[0083] Specifically, the bottom of the discharge chamber 311 is inclined, and a discharge pipe 301 for discharging quartz sand is installed on the side of the bottom end of the discharge chamber 311;

[0084] The sides of the bottom end of the liquid storage chamber 312 are respectively installed with a liquid replacement inlet pipe 302 and a liquid replacement outlet pipe 303;

[0085] The middle of the top of the tank upper seat 1 is provided with a feed opening which gradually decreases in diameter downwards and is directly opposite to the middle of the top of the tank inner cylinder 202, and the feed opening can be closed;

[0086] The interior of the tank upper seat 1 is provided with a ring groove which can be connected to all the exhaust pipes 102 , and the outer side of the tank upper seat 1 is provided with an exhaust pipe 101 which can be connected to the ring groove.

[0087] It should be noted that, under the guidance of the discharge chamber 311 structure, the quartz sand in the discharge chamber 311 can be more smoothly guided to the discharge pipe 301, thereby making the discharge smoother.

[0088] The feed port allows the quartz sand to fall directly onto the lower material guide assembly 5 during feeding, and the feed port is closed during acid leaching, so that the exhaust gas can enter the annular groove from the exhaust pipe 102 and then be discharged through the exhaust pipe 101 for centralized treatment, thereby avoiding pollution caused by direct discharge of the exhaust gas.

[0089] Preferably, the lifting assembly 6 includes a second spiral guide blade 601, a driven ring 602, a second stable connecting column 603, and an opening and closing ring plate 604;

[0092] The bottom end of the second stable connecting column 603 extends into the interior of the opening and closing ring plate 604 and can slide in a circular trajectory within the opening and closing ring plate 604;

[0093] When the opening and closing ring plate 604 is in a closed open state, the opening and closing ring plate 604 contacts the material guide cone 304 and the inner wall of the outer cylinder 201 of the tank body, and the friction force between the opening and closing ring plate 604 and the outer cylinder 201 of the tank body is greater than the friction force between the opening and closing ring plate 604 and the second stable connecting column 603.

[0094] It should be noted that, through the transmission of the driven ring 602, the second stable connecting column 603 and the second spiral guide blade 601 can rotate together, and by driving the second stable connecting column 603 to rise and fall, the opening and closing ring plate 604 can rise and fall together. It should be noted that since the friction between the opening and closing ring plate 604 and the outer tube 201 of the tank body is greater than the friction between the opening and closing ring plate 604 and the second stable connecting column 603, the opening and closing ring plate 604 does not rotate at this time, and only the second stable connecting column 603 rotates.
