Description

Technical Field

[0001] The present invention relates to the technical field of quartz sand purification equipment, specifically high-purity quartz sand purification equipment. Background Art

[0002] During the purification process of quartz sand, hydrogen chloride gas is usually used to react with quartz sand at high temperature for purification. Currently, the quartz sand purification equipment in use is generally a vertical high-temperature reaction furnace or a horizontal high-temperature reaction furnace. The purification effect of a single high-temperature reaction furnace on quartz sand is limited. Moreover, the existing quartz sand is not preheated before purification, and the temperature rise of quartz sand in the vertical or horizontal high-temperature reaction furnace is slow, which reduces the purification quality of quartz sand. In addition, the traditional quartz furnace tube is fixed with bolts, and the force of the bolts acts on the quartz tube in a multi-point radial manner. This structure is not only troublesome to install and adjust, but also easily causes quartz to break. The traditional quartz furnace tube is driven by multiple motors separately, and the use of multiple motors results in a high cost of the purification equipment.

[0003] Therefore, we propose a high-purity quartz sand purification equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-purity quartz sand purification equipment to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-purity quartz sand purification equipment, including a hopper, a preheating frame, a furnace tube support group, a preheating furnace, a rotating tube motor, a high-temperature furnace frame, a horizontal high-temperature reaction furnace, a vertical high-temperature reaction furnace, and a cold sand frame. A vibrating feeder is arranged at the bottom of the hopper, a vibrator is arranged at the bottom of the vibrating feeder, a preheating furnace tube is arranged at the right end of the preheating furnace, a sand receiving hopper I is arranged at the left end of the preheating furnace, a quartz furnace tube is arranged at the left end of the horizontal high-temperature reaction furnace, a sand receiving hopper II is arranged at the left end of the quartz furnace tube, a sand distributing hopper is arranged at the bottom of the sand receiving hopper II, the bottom end of the sand distributing hopper is connected to the top of the vertical high-temperature reaction furnace, a sand receiving hopper III is arranged at the lower part of the vertical high-temperature reaction furnace, a cold sand tube is arranged on the left side of the sand receiving hopper III, and the left end of the cold sand tube is connected to a cold sand box.

[0006] Further, exhaust ports are arranged on both the sand receiving hopper I and the sand distributing hopper.

[0007] Further, inlet pipes are arranged at the left end of the sand receiving hopper II and the bottom of the vertical high-temperature reaction furnace.

[0008] Further, the preheating furnace, the horizontal high-temperature reaction furnace, and the cold sand box are all supported by the furnace tube support group.

[0009] Further, a linkage shaft I is arranged on the rotating tube motor.

[0010] Further, the furnace tube support group includes a furnace tube roller group. On both sides of the bottom of the furnace tube roller group, there are transmission seats. At the front end of the transmission seat, there is a transmission roller, and a linkage shaft II is arranged on the transmission seat.

[0011] Further, the furnace tube roller group includes rollers. On one side of the roller, there is an elastic net, and a hoop is arranged on the roller.

[0012] Further, the transmission seat includes a worm and a worm gear.

[0013] Further, the transmission seats arranged on both sides of the bottom of the furnace tube roller group are connected by a linkage shaft II.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the quartz sand is fed into the preheating furnace tube for preheating, the high-temperature quartz sand enters the horizontal high-temperature reaction furnace, which can quickly raise the temperature of the quartz sand to the temperature required for reaction with the purification gas, shorten the heating time, increase the reaction time between the quartz sand and the purification gas, improve the product quality. After the quartz sand comes out of the horizontal high-temperature reaction furnace, it enters the vertical high-temperature reaction furnace through the sand separating hopper for secondary full reaction with the purification gas to remove residual impurities. The quartz sand drifts downwards into an environment with high-temperature purification gas, and the contact between the sand and the purification gas is more sufficient, and the reaction is more complete. The secondary purification makes up for the insufficient reaction in the previous stage, effectively improving the purification quality of the quartz sand.

[0015] 2. The hoop is directly fixed on the roller with bolts, which is convenient for installation. The way of the hoop plus the elastic net can effectively protect the quartz furnace tube from being easily broken. Because the hoop and the elastic net have a large stress area and act axially on the quartz furnace tube, and with the buffering effect of the elastic net, the quartz furnace tube is fixed by the clamping method, which can better protect the quartz furnace tube. Moreover, by driving multiple transmission seats with a rotating tube motor 8, the preheating furnace and the horizontal high-temperature reaction furnace can rotate simultaneously, reducing the use of the rotating tube motor and improving the economic benefits of the equipment.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-6, the present invention provides a technical solution: a high-purity quartz sand purification device, including a hopper 1, a preheating frame 4, a furnace tube support group 6, a preheating furnace 7, a rotary tube motor 8, a high-temperature furnace frame 11, a horizontal high-temperature reaction furnace 10, a vertical high-temperature reaction furnace 15, and a cold sand frame 19. A vibrating hopper 2 is provided at the bottom of the hopper 1, a vibrator 3 is provided at the bottom of the vibrating hopper 2, a preheating furnace tube 5 is provided at the right end of the preheating furnace 7, a sand receiving hopper 1 is provided at the left end of the preheating furnace 7, a quartz furnace tube 12 is provided at the left end of the horizontal high-temperature reaction furnace 10, a sand receiving hopper 2 is provided at the left end of the quartz furnace tube 12, a sand distributing hopper 14 is provided at the bottom of the sand receiving hopper 2, the bottom end of the sand distributing hopper 14 is connected to the top of the vertical high-temperature reaction furnace 15, a sand receiving hopper 3 is provided at the lower part of the vertical high-temperature reaction furnace 15, a cold sand tube 17 is provided on the left side of the sand receiving hopper 3, and the left end of the cold sand tube 17 is connected to a cold sand box 18. Quartz sand is added into the hopper 1, the vibrator 3 works, so that the quartz sand enters the vibrating hopper 2 through the bottom of the hopper 1. The continuous vibration of the vibrator 3 prevents the quartz sand from blocking the hopper 1. The quartz sand enters the preheating furnace 7 through the vibrating hopper 2 for preheating. At the same time, the rotary tube motor 8 is started to drive the preheating furnace 7 to rotate, so that the quartz sand is uniformly preheated. The preheated quartz sand enters the horizontal high-temperature reaction furnace 10 through the sand receiving hopper 1 to heat the quartz sand. At the same time, hydrogen chloride gas is introduced through the air inlet pipe 20 to react and purify the quartz sand in the horizontal high-temperature reaction furnace 10. The quartz sand that has undergone primary purification enters the sand distributing hopper 14 through the sand receiving hopper 2. The quartz sand enters the vertical high-temperature reaction furnace 15 through the sand distributing hopper 14. The air inlet pipe 20 provided at the bottom of the vertical high-temperature reaction furnace 15 passes hydrogen chloride gas to perform secondary purification on the quartz sand, improving the purification quality of the quartz sand. The purified quartz sand enters the cold sand tube 17 through the sand receiving hopper 3 and finally enters the cold sand box 18 for rapid cooling. After the quartz sand is preheated by being sent into the preheating furnace tube 5, the high-temperature quartz sand entering the horizontal high-temperature reaction furnace 10 can quickly raise the temperature of the quartz sand to the temperature required for reaction with the purification gas, shortening the heating-up time and increasing the reaction time between the quartz sand and the purification gas, thus improving the product quality. After the quartz sand comes out of the horizontal high-temperature reaction furnace 10, it enters the vertical high-temperature reaction furnace 15 through the sand distributing hopper for secondary full reaction with the purification gas to remove residual impurities. The quartz sand drifts downwards in an environment with high-temperature purification gas, and the contact between the sand and the purification gas is more sufficient and the reaction is more complete. The secondary purification makes up for the insufficient reaction in the previous stage and effectively improves the purification quality of the quartz sand. After the quartz sand is secondary purified by the vertical high-temperature reaction furnace 15, it flows through the sand receiving hopper into the cold sand tube 17 and the cold sand box 18 to be cooled to a temperature close to normal temperature for packaging. Moreover, the installation positions and sequences of the horizontal high-temperature reaction furnace 10 and the vertical high-temperature reaction furnace 15 of this purification device can be flexibly adjusted according to the requirements of the installation site.

[0020] Reference Example: Exhaust ports 21 are provided on both the sand receiving hopper 9 and the sand distributing hopper 14. The gas after reacting and purifying with quartz stone is discharged through the exhaust port 21. Inlets 20 are provided at both the left end of the second sand receiving hopper 13 and the bottom of the vertical high-temperature reaction furnace 15. The inlets 20 react with quartz sand through hydrogen chloride gas to purify the quartz sand.

[0021] Reference Example: The preheating furnace 7, the horizontal high-temperature reaction furnace 10, and the cold sand box 18 are all supported by the furnace tube support group 6. A first linkage shaft 64 is provided on the rotating tube motor 8. The furnace tube support group 6 includes a furnace tube roller group 62. On both sides of the bottom of the furnace tube roller group 62, there are transmission seats 61. At the front end of the transmission seat 61, there is a transmission roller 63. A second linkage shaft 65 is provided on the transmission seat 61. The preheating furnace 7, the horizontal high-temperature reaction furnace 10, and the cold sand box 18 are all supported by multiple groups of transmission seats 61. The transmission seats 61 are connected by the second linkage shaft 65. The transmission seats 61 between the preheating furnace 7, the horizontal high-temperature reaction furnace 10, and the cold sand box 18 are connected by the first linkage shaft 64. By driving multiple transmission seats 61 with one rotating tube motor 8, the preheating furnace 7 and the horizontal high-temperature reaction furnace 10 can rotate simultaneously, reducing the use of the rotating tube motor 8 and improving the economic benefits of the equipment.

[0022] Reference Example: The furnace tube roller group 62 includes rollers 621. On one side of the roller 621, there is an elastic net 623. A hoop 622 is provided on the roller 621. The quartz furnace tube is fixed by the method of the hoop 622 plus the elastic net 623. The hoop 622 is directly fixed on the roller 621 with bolts, which is convenient for installation. The method of the hoop 622 plus the elastic net 623 can effectively protect the quartz furnace tube from being easily broken because the hoop 622 and the elastic net 623 have a large stress area acting axially on the quartz furnace tube, and with the buffering effect of the elastic net 623, fixing the quartz furnace tube in a clamping manner can better protect the quartz furnace tube.

[0023] Reference Example: The transmission seat 61 includes a worm 611 and a worm gear 612. The transmission seats 61 provided on both sides of the bottom of the furnace tube roller group 62 are connected by the second linkage shaft 65. The worm gear 612 and the worm 611 are used for the transmission seat 61. The transmission seat 61 has a low failure rate, smooth transmission, convenient installation, low noise, and is also convenient for maintenance, saving a large amount of manpower and material resources.
