[0002] High-purity quartz sand is a small particle of quartz that is processed by crushing quartz stone. Quartz stone is a non-metallic mineral that is hard, wear-resistant, and chemically stable. It belongs to silicate minerals. The main purpose of heating and purifying high-purity quartz sand is to make the impurities in high-purity quartz sand undergo physical or chemical changes by heating, thereby separating them from high-purity quartz sand and improving the purity of high-purity quartz sand. High-purity high-purity quartz sand is widely used in glass, ceramics, semiconductors and other industries.

Utility Model Content

[0004] The utility model aims to provide a high-purity quartz sand double-helix heating reaction device to solve the problem of uneven heating and long reaction time caused by the existing high-purity quartz sand heating tubes arranged side by side.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-purity quartz sand double-helix heating reaction device, comprising two support frames separated from each other, a furnace body is commonly installed on the top of the two support frames, a plurality of heating tubes are installed in the furnace body, and the plurality of heating tubes are arranged in a double-helix structure. An inlet and outlet are installed on the furnace body, and support members are connected to both sides of the furnace body. The ends of the two support members that are respectively away from each other can be rotated on the two support frames, and one of the support members is provided with a liquid inlet pipe.

[0006] Furthermore, two inlet and outlet ports are provided, the two inlet and outlet ports are symmetrically located at the axis of the furnace body, and valves are installed at both inlet and outlet ports.

[0007] Furthermore, the liquid inlet pipe is connected to the injection device via a rotatable joint away from the support member.

[0008] Furthermore, a pressure relief device is installed on the furnace body.

[0009] Furthermore, the support member is mounted on an inner sleeve, and the inner sleeve is rotatably arranged on the support frame via a plurality of balls.

[0010] Furthermore, a motor is installed on the top of one side of the two support frames away from each other, and a driving gear is installed on the output shaft of the motor. A driven gear is installed on the furnace body, and the driving gear is meshed and connected with the driven gear.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The high-purity quartz sand double-helix heating reaction device has a heating tube with a double-helix structure. When the furnace body rotates, due to the existence of the double-helix structure, the high-purity quartz sand will continuously contact with the heating tube during movement, and will be blocked and guided by the heating tube, so that the high-purity quartz sand will form a certain circulation, blocking and flipping flow around the heating tube. In addition, the double-helix structure can also increase the contact area and contact time between the high-purity quartz sand and the heating tube. The high-purity quartz sand will continuously contact and exchange heat with the heating tube during the flow process. This method will make the temperature of the high-purity quartz sand more uniform and can improve the heating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] See also Figure 2 The utility model provides a high-purity quartz sand double-helix heating reaction device, which includes two support frames 10 separated from each other, and a furnace body 20 is installed on the top of the two support frames 10.

[0024] See also Figure 2 Support members 210 are connected to both sides of the furnace body 20, and the ends of the two support members 210 that are away from each other are movably arranged on two support frames 10, one of the support members 210 is provided with a liquid inlet pipe 211, and the liquid inlet pipe 211 is connected to the injection device away from the support member 210 through a rotatable joint, and liquid can be injected into the furnace body 20 through the injection device and the liquid inlet pipe 211. In order to allow the liquid to be discharged separately from the furnace body 20, a drain pipe 202 is separately arranged on the furnace body 20, and a filter can be used at the drain pipe 202 to prevent the outflow of high-purity quartz sand.

[0025] A pressure relief device is installed on the furnace body 20 to avoid the problem of furnace explosion caused by excessive pressure inside the furnace body 20.

[0026] See also Figure 2 and Figure 3 A plurality of heating tubes 220 are installed in the furnace body 20, and the plurality of heating tubes 220 are in a double helix structure.

[0027] See also Figure 2 and Figure 3The double helix structure itself has a spiral layout, which makes the heating tube 220 present an asymmetric, continuously curved shape in the furnace body. When the furnace body starts to rotate, this asymmetric layout will cause the high-purity quartz sand to produce different flow patterns and speeds around the heating tube 220. Due to the rotation of the furnace body, the high-purity quartz sand will be affected by the centrifugal force and move toward the outer wall of the furnace body. However, due to the existence of the double helix structure, the high-purity quartz sand will continuously contact the heating tube 220 during the movement, and will be blocked and guided by the heating tube 220. This blocking and guiding will cause the high-purity quartz sand to form a certain circulation blocking and flipping flow around the heating tube 220; in addition, the double helix structure can also increase the contact area and contact time between the high-purity quartz sand and the heating tube 220. Since the heating tube 220 presents a spiral layout, the high-purity quartz sand will continuously contact and exchange heat with the heating tube 220 during the flow process. This contact and exchange will make the temperature of the high-purity quartz sand more uniform and can improve the heating efficiency.

[0028] See also Figure 2 and Figure 4 The furnace body 20 is provided with two inlets and outlets, which are symmetrically located in front and back of the axis of the furnace body 20, and both inlets and outlets are provided with valves 201 that can be opened or closed. The inner wall of the furnace body 20 is inclined to arrange the inlets and outlets, so as to facilitate the outflow of high-purity quartz sand.

[0029] See also Figure 2 and Figure 4 A motor 110 is installed on the top of the side of the two support frames 10 away from each other. A driving gear 120 is installed on the output shaft of the motor 110. Driven gears 230 are installed on both sides of the furnace body 20. The driving gear 120 is meshed and connected with the driven gear 230. The driving gears 120 on the output shafts of the two motors 110 jointly drive the furnace body 20 to rotate.

[0030] See also Figure 2 and Figure 4 The support member 210 is installed on the inner sleeve 240, and the inner sleeve 240 is installed in the circular groove 101 of the support frame 10 through a plurality of balls 241. An annular groove is provided on the inner wall of the circular groove 101, and an annular groove is also provided on the inner sleeve 240. The annular groove is used to limit the ball 241 to prevent the ball 241 from moving out from between the circular groove 101 and the inner sleeve 240. The installation method between the inner sleeve 240, the ball 241 and the circular groove 101 is the same as the bearing principle, which reduces the friction between the support member 210 and the support frame 10.

[0031] The working principle and use process of the utility model are as follows: open a valve 201, put high-purity quartz sand in, inject liquid for cleaning at the same time, start the motor 110, the two motors 110 drive the two driving gears 120 to rotate through the output shaft, and the two driving gears 120 jointly drive the furnace body 20 to rotate through the two driven gears 230, so that the high-purity quartz sand is constantly turned in the furnace body 20 and heated by the double-helix structure heating tube 220 group.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
