Description

Technical Field

[0001] The invention relates to the technical field of quartz sand calcining, in particular to a purification furnace for high-purity quartz sand. Background Art

[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 an important industrial mineral raw material and a non-chemical hazardous substance. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries. Before being used in industrial production, quartz sand needs to be purified to maximize the use effect of quartz sand. The purification techniques include scrubbing and desludging, magnetic separation, acid leaching, calcination, etc.

[0003] For example, an automatic temperature control transformer with publication number CN117663771A is provided with a horizontal plate, a connecting rod and a calcining cylinder. Through the linkage of the above structure, the horizontal plate is driven by a driving source to rotate, and then the horizontal plate drives the connecting rod to move up and down on the top of the calcining body. The two connecting rods move up and down to realize the inclination of the calcining cylinder. When loading, the internal space is fully utilized. At the same time, during the calcining process, the internal quartz sand can be moved inside by tilting the calcining cylinder, so that the quartz sand can be turned over. During the subsequent calcination and purification, it can be more uniform and the purification effect is better. However, in actual use, when the stone is During the calcination of quartz sand, the crushing knife moves and encounters quartz sand. It is difficult to move due to the resistance of the quartz sand, which makes it inconvenient to stir the quartz sand. After being heated at high temperature, the quartz sand will melt and easily clump, which is inconvenient for subsequent discharge. If the quartz sand is stirred mechanically after melting, it is easy to cause the quartz sand to stick together if it is stirred mechanically, which makes it inconvenient for subsequent discharge of the quartz sand. In addition, during the calcination and heating process, the quartz sand is prone to oxidation reaction and easily reacts with oxygen to form silicon oxide, which will lead to quality loss of the quartz sand and has certain usage defects.

[0004] Therefore, we propose a purification furnace for high-purity quartz sand in order to solve the problems raised above. Summary of the Invention

[0031] Compared with the prior art, the present invention has the following beneficial effects: the furnace for purifying high-purity quartz sand can be used to stir the quartz sand by blowing air when calcining the quartz sand. The airflow disturbs the quartz sand, and the quartz sand can be stirred even in a molten state to avoid agglomeration and adhesion of the quartz sand. In addition, during the stirring process, the quartz sand can be prevented from being oxidized to form silicon oxides at high temperatures, thereby avoiding loss of quartz sand quality.

[0032] 1. When calcining quartz sand, the right end of the calcining cylinder is tilted by the reduction motor, and then the quartz sand can be put into the calcining cylinder, and then the calcining cylinder is made horizontal, and the heating structure sprays fire to heat the calcining cylinder. During the heating process, the reduction motor is started between fifteen and thirty minutes to make the calcining cylinder swing back and forth. At the same time as the reduction motor is started, argon is introduced into the inflation tube, and the inflation tube can be made of high-temperature resistant material. Argon can be blown to the quartz sand inside the calcining cylinder through the blowing tube, and the quartz sand is stirred by the air flow disturbance. When the calcining cylinder is rotated and tilted, the movable ring slides on the calcining cylinder, which can push the limit rod to slide on the limit frame and drive the movable rod to tilt. As the calcining cylinder tilts, the movable rod can drive the column rod to slide on the two guide frames. After the calcining cylinder tilts, the column rod slides on the guide frame. The quartz sand is stirred by the air blowing pipe, and the position of the air blowing pipe can be moved, which can increase the stirring range and improve the practicality. After the argon gas enters the calcining tube, the oxygen can be pushed out of the calcining tube, which can protect the calcination of the quartz sand. When the quartz sand is calcined, the quartz sand can be stirred by blowing. The quartz sand is disturbed by the air flow, and the quartz sand can be stirred even in the molten state to avoid agglomeration and adhesion of the quartz sand. In the stirring process, the quartz sand can be prevented from being oxidized to form silicon oxides at high temperature, thereby avoiding the loss of quartz sand quality.

[0033] 2. When argon is flushed into the calcining process, the gas inside the calcining cylinder can be pushed into the outlet pipe. Since the air is blown through the air pipe, a certain amount of dust will be blown up. The dust can enter the heat exchange coil along the outlet pipe and the metal bellows. The water tank is filled with cooling water. The high-temperature gas can be cooled through the heat exchange coil and the waste heat can be recovered. After that, the gas can enter the spray box. Quartz sand will produce a certain amount of acidic waste gas during the calcination and impurity removal process. The calcining cylinder can drive the limit rod to move back and forth during the reciprocating swing. After one side of the limit rod moves, the rotating shaft can be driven to rotate through the engagement of the tooth plate and the rotating gear. The cooperation of the first sprocket and the second sprocket can drive the rotating rod to rotate, thereby making the rotating The column block on the disc rotates in a circle, and after the column block rotates in a circle, it can drive the sliding rod and the piston to move back and forth on the cylinder. When the piston moves to the right in the cylinder, the one-way valve inside the installation pipe is closed, the one-way valve inside the liquid extraction pipe is opened, and the liquid storage tank is filled with alkali solution, which can be pumped into the cylinder. Then, when the piston moves to the left, the one-way valve inside the installation pipe is opened, and the one-way valve inside the liquid extraction pipe is closed, so that the alkali solution can be filled into the spray pipe, and the alkali solution can be sprayed out through the nozzle, so as to perform alkali washing on the waste gas and treat the waste gas. While the quartz sand is turned and stirred, the discharged gas can be cooled, and the dust and acid gas in the gas can be treated, thereby improving practicality.

[0034] After that, the ceramic handle is released and the rotating rod is reset under the action of the torsion spring, so that the positioning block abuts against the arc groove, so that the movable frame can be limited, so that the baffle is limited after closing, thereby facilitating the opening and closing of the baffle by the staff, thereby improving the practicality.

[0065] Example 3: Figure 2 and Figure 9-10 As shown, when the two baffles 403 are opened, the ceramic handle 407 can be rotated to drive the rotating rod 405 to rotate on the movable frame 4042, so that the positioning block 408 rotates inside the arc groove 411, so that the positioning block 408 is aligned with the slot 410, and then the ceramic handle 407 can be pulled to make the movable frame 4042 slide on the fixed rod 4041, so that the positioning block 408 is disengaged from the slot 410, so that the baffle 403 loses its limit, and the baffle 403 can make the connecting frame 402 rotate on the support plate 401 under the action of gravity, and the baffle 403 is directly opened, which is convenient for adding and taking out materials. When closing, the two baffles 403 are fitted together on one side, and then the ceramic handle 407 is rotated and pushed. At this time, the positioning block 408 is aligned with the slot 410, so that the movable frame 4042 moves the positioning block 408 and inserts it into the slot 410, and then the positioning block 408 is abutted against the arc groove 411, and then the ceramic handle 407 is released, and the rotating rod 405 is reset under the action of the torsion spring 406, so that the positioning block 408 is abutted against the arc groove 411, so that the movable frame 4042 can be limited, so that the baffle 403 is limited after closing, thereby facilitating the staff to open and close the baffle 403, thereby improving practicality.

[0066] Working principle: When using the furnace for the purification of high-purity quartz sand, first, according to Figures 1-10As shown, when quartz sand is calcined, the right end of the calcining tube 103 is tilted by the reduction motor 106, and then the quartz sand can be put into the calcining tube 103, and then the calcining tube 103 is made horizontal, and the heating structure sprays fire to heat the calcining tube 103. During the heating process, the reduction motor 106 is started between fifteen and thirty minutes to make the calcining tube 103 swing back and forth. At the same time as the reduction motor 106 is started, argon is introduced into the inflation tube 201, and the inflation tube 201 can be made of high-temperature resistant material. Argon can be blown to the quartz sand inside the calcining tube 103 through the blowing tube 202, and the quartz sand is stirred by the air flow disturbance. When the calcining tube 103 is rotated and tilted, the movable ring 212 slides on the calcining tube 103, which can push the limit rod 213 to the limit frame 214. The movable rod 203 slides upward and can drive the movable rod 203 to tilt. As the calcining tube 103 tilts, the movable rod 203 can drive the column rod 205 to slide on the two guide frames 207. After the calcining tube 103 tilts, the column rod 205 slides on the guide frames 207. The column rod 205 can drive the movable rod 203 to move by abutting against the guide frames 207. After the movable rod 203 moves, it slides on the movable sleeve 208, and then drives the inflation tube 201 to move. After the calcining tube 103 tilts, the quartz sand can be turned over and stirred through the blowing tube 202. The position of the blowing tube 202 can be moved, which can increase the stirring range and improve practicality. After the argon gas enters the calcining tube 103, it can push oxygen out of the calcining tube 103, so as to protect the calcination of the quartz sand.

[0067] When argon is injected during the calcining process, the gas inside the calcining tube 103 can be pushed into the outlet pipe 301. Since the blowing pipe 202 blows air, a certain amount of dust will be blown up. The dust can enter the heat exchange coil 305 along the outlet pipe 301 and the metal bellows 303. The water tank 304 is filled with cooling water. The high-temperature gas can be cooled by the heat exchange coil 305, and the waste heat can be recovered. After that, the gas can enter the spray box 3051. Quartz sand will produce a certain amount of acidic waste gas during the calcination and impurity removal process. The calcining tube 103 can drive the limit rod 213 to move back and forth during the reciprocating swing. After the limit rod 213 on one side moves, it can pass through the tooth plate 324 and The meshing of the rotating gear 322 drives the rotating shaft 320 to rotate, and the cooperation of the first sprocket 318 and the second sprocket 321 can drive the rotating rod 312 to rotate, thereby causing the column block 314 on the turntable 313 to rotate in a circle. After the column block 314 rotates in a circle, it can drive the sliding rod 315 and the piston 316 to move back and forth on the cylinder 309. When the piston 316 moves to the right in the cylinder 309, the one-way valve inside the installation tube 307 is closed, the one-way valve inside the liquid extraction tube 310 is opened, and the liquid storage tank 306 is filled with alkali solution, which can be pumped into the cylinder 309. Then, when the piston 316 moves to the left, the one-way valve inside the installation tube 307 is opened, and the liquid extraction tube 310 is opened. The internal one-way valve is closed, so that alkali liquid can be filled into the spray pipe 308, and the alkali liquid can be sprayed out through the nozzle to perform alkali washing on the exhaust gas and treat the exhaust gas. When the two baffles 403 are opened, the ceramic handle 407 can be rotated to drive the rotating rod 405 to rotate on the movable frame 4042, so that the positioning block 408 rotates inside the arc groove 411, so that the positioning block 408 is aligned with the slot 410, and then the ceramic handle 407 can be pulled to make the movable frame 4042 slide on the fixed rod 4041, so that the positioning block 408 is disengaged from the slot 410, so that the baffle 403 loses its limit, and the baffle 403 can make the connecting frame 402 support under the action of gravity. The support plate 401 is rotated, and the baffle 403 is directly opened to facilitate the addition and removal of materials. When the baffle 403 is closed, the two baffles 403 are fitted on one side, and then the ceramic handle 407 is rotated and pushed. At this time, the positioning block 408 is aligned with the slot 410, so that the movable frame 4042 moves the positioning block 408 and inserts it into the slot 410, and then the positioning block 408 is abutted against the arc groove 411, and then the ceramic handle 407 is released, and the rotating rod 405 is reset under the action of the torsion spring 406, so that the positioning block 408 is abutted against the arc groove 411, so that the movable frame 4042 can be limited, so that the baffle 403 is limited after closing.
