Description

Technical Field

[0001] The utility model belongs to the technical field of quartz sand production, in particular to a high-temperature calcining and water quenching device for removing gas-liquid inclusions in quartz sand. Background Art

[0002] In addition to the well-known metal elements, harmful impurities in quartz sand include micron- and even nano-scale gas-liquid inclusions, which are not only common but also more difficult to remove.

[0003] When the existing high-temperature calcination water quenching device is in use, two quartz tubes are generally supported by three supporting wheels, and the hub installed on the quartz tube is used to drive it to rotate, and then quartz sand is placed inside the quartz tube. The temperature of the quartz sand in the furnace is 1100°C. After leaving the insulation layer of the box-type electric furnace and reaching the discharge port, it freely falls and contacts pure water for water quenching. During water quenching, the temperature of the quartz sand has dropped to about 900-750°C, and the maximum temperature difference does not exceed 880°C, which results in a very limited effect of opening the gas-liquid inclusions. Therefore, a high-temperature calcination water quenching device for removing gas-liquid inclusions in quartz sand is proposed to solve the problems raised in the background technology.

[0004] In order to solve the problems raised in the above background technology, the utility model provides a high-temperature calcination and water quenching device for removing gas-liquid inclusions in quartz sand, which has the advantage of achieving a better effect of removing gas-liquid inclusions.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature calcination and water quenching device for removing gas-liquid inclusions in quartz sand, comprising a box-type electric furnace, one side of the box-type electric furnace is fixedly connected to a support frame, the interior of the box-type electric furnace is movably connected to two pipes located above the support frame, the surface of the pipe away from the support frame is provided with a first discharge port at a 72-degree angle, the end of the pipe away from the support frame is fixedly connected to a cylindrical cam, the surface of the cylindrical cam is provided with a guide groove, the interior of the pipe is movably connected to a rotating drum, the surface of the rotating drum is provided with a second discharge port at a 72-degree angle, the end of the rotating drum close to the cylindrical cam is movably clamped with a round rod, the end of the round rod away from the rotating drum is provided with a convex rod at a 180-degree angle, the outer wall of the rotating drum is provided with square blocks at equal angles, a quartz glass water tank is provided inside the box-type electric furnace, and a quartz water pipe is fixedly connected to one side of the quartz glass water tank.

[0006] Preferably, one end of the pipe close to the support frame passes through the outer wall of the box-type electric furnace and extends to the outside of the box-type electric furnace. The pipe is made of silicon carbide ceramic material or high-aluminum heat-resistant quartz glass.

[0007] Preferably, one side of the rotating drum is in an inclined shape, the second discharge port coincides with the first discharge port, and the length of the second discharge port is greater than that of the first discharge port.

[0008] Preferably, the inner wall of the first discharge port is provided with a chute at an annular equal angle, and the square block is movably engaged in the inside of the chute, and the chute is used to circumferentially limit the square block when the first discharge port rotates.

[0009] Preferably, the round rod is located in the middle of the cylindrical cam, the convex rod is movably engaged in the interior of the guide groove, and the round rod is corrugated.

[0010] Preferably, the inner wall of the box-type electric furnace is provided with a straight slot that matches the convex rod, and the straight slot is used to circumferentially limit the convex rod when the cylindrical cam rotates.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model achieves a better effect of removing gas-liquid inclusions through the coordination between structures such as the pipeline, the first discharge port, the quartz glass water tank and the quartz water pipe. The pipeline adopts silicon carbide ceramic material or high-aluminum heat-resistant quartz glass as a carrier for calcining high-purity quartz sand, so that the calcination temperature can be increased to above 1300°C without polluting the high-purity quartz sand. The quartz glass water tank is located inside the box-type electric furnace and below the first discharge port, so that the high-purity quartz sand after high-temperature calcination can be water quenched immediately when it leaves the pipeline, so that the water quenching temperature difference can be stabilized at above 1200°C, thereby improving the overall effect of the device in removing gas-liquid inclusions.

[0014] The utility model cooperates with the cylindrical cam, the rotating drum, the round rod and the convex rod to facilitate the quartz sand to fall from the inside of the pipe better, and the square block is circumferentially limited by the sliding groove, so that the rotating drum is driven to rotate when the pipe rotates. When the cylindrical cam rotates, the convex rod drives the round rod to move back and forth along the trajectory of the guide groove, so that the quartz sand inside the rotating drum is driven by the round rod to vibrate, thereby reducing the friction between the quartz sand and the inner wall of the rotating drum, so that the quartz sand is more likely to fall into the interior of the quartz glass water tank through the second discharge port and the first discharge port during the rotation and movement of the rotating drum.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0021] like Figures 1 to 4 As shown, the utility model provides a high-temperature calcination and water quenching device for removing gas-liquid inclusions in quartz sand, including a box-type electric furnace 1, one side of the box-type electric furnace 1 is fixedly connected to a support frame 16, and the interior of the box-type electric furnace 1 is movably connected to two pipes 2 located above the support frame 16, and the surface of the pipe 2 away from the support frame 16 is provided with a first discharge port 3 at a 72-degree angle, the end of the pipe 2 away from the support frame 16 is fixedly connected to a cylindrical cam 4, and a guide groove 5 is provided on the surface of the cylindrical cam 4, and the interior of the pipe 2 is movably connected to a rotating drum 6, and the surface of the rotating drum 6 is provided with a second discharge port 7 at a 72-degree angle, and the end of the rotating drum 6 close to the cylindrical cam 4 is movably clamped with a round rod 8, and the end of the round rod 8 away from the rotating drum 6 is provided with a convex rod 9 at a 180-degree angle, and the outer wall of the rotating drum 6 is provided with square blocks 10 at equal angles in a ring shape, and a quartz glass water tank 13 is provided inside the box-type electric furnace 1, and a quartz water pipe 14 is fixedly connected to one side of the quartz glass water tank 13.

[0022] The above solution is adopted: the square block 10 is circumferentially limited by the slide groove 11, so that the rotating drum 6 is driven to rotate when the pipe 2 rotates, and the convex rod 9 drives the round rod 8 to move back and forth along the trajectory of the guide groove 5 when the cylindrical cam 4 rotates, so that the quartz sand inside the rotating drum 6 is driven by the round rod 8 to vibrate, thereby reducing the friction between the quartz sand and the inner wall of the rotating drum 6, so that the quartz sand is more likely to fall into the interior of the quartz glass water tank 13 through the second discharge port 7 and the first discharge port 3 during the rotation and movement of the rotating drum 6.

[0023] like Figures 2 to 4 As shown, one end of the pipe 2 close to the support frame 16 passes through the outer wall of the box-type electric furnace 1 and extends to the outside of the box-type electric furnace 1. The pipe 2 is made of silicon carbide ceramic material or high-aluminum heat-resistant quartz glass. One side of the rotating drum 6 is inclined. The second discharge port 7 coincides with the first discharge port 3. The length of the second discharge port 7 is greater than the length of the first discharge port 3. The inner wall of the first discharge port 3 is provided with a chute 11 at an equal angle in a ring shape. The square block 10 is movably clamped in the inside of the chute 11. The chute 11 is used to circumferentially limit the square block 10 when the first discharge port 3 rotates.

[0024] The above solution uses silicon carbide ceramic material for pipe 2. This material, or high-aluminum, heat-resistant quartz glass, can increase the operating temperature from 1100°C to 1300°C, significantly increasing the calcination temperature. Furthermore, silicon carbide ceramic pipes oxidize at high temperatures to form a protective silicon dioxide layer, preventing contamination of the high-purity quartz sand product.

[0025] One side of the drum 6 is in an inclined shape. Compared with a vertical inlet, the inclined inlet reduces the direct collision between the quartz sand and the edge of the inlet of the drum 6, thereby preventing the quartz sand from rebounding or accumulating at the inlet of the drum 6 due to the collision, thereby facilitating the quartz sand to enter the interior of the drum 6 through the inclined surface.

[0026] like Figure 2 As shown in the figure, the round rod 8 is located in the middle of the cylindrical cam 4, the convex rod 9 is movably engaged with the inside of the guide groove 5, the round rod 8 is corrugated, and the inner wall of the box-type electric furnace 1 is provided with a straight slot 12 that cooperates with the convex rod 9. The straight slot 12 is used to circumferentially limit the convex rod 9 when the cylindrical cam 4 rotates. The quartz glass water tank 13 is located below the rotating drum 6. The quartz water pipe 14 passes through the outer wall of the box-type electric furnace 1 and extends to the outside of the box-type electric furnace 1. A door panel 15 is provided on one side of the box-type electric furnace 1.

[0027] The above solution is adopted: the quartz glass water tank 13 is located inside the box-type electric furnace 1, below the first discharge port 3, so that the high-purity quartz sand after high-temperature calcination is immediately water quenched at the moment it leaves the pipe 2, thereby stabilizing the water quenching temperature difference at above 1200°C, thereby improving the overall effect of the device in removing gas-liquid inclusions.

[0028] The working principle and use process of the utility model are as follows: the operator puts quartz sand into the interior of the pipe 2, and then the quartz sand moves toward the direction of the cylindrical cam 4 through the rotation of the pipe 2. During the movement, the quartz sand is heated and calcined by the box-type electric furnace 1. The above belongs to the existing technology;

[0029] When the pipe 2 rotates, it drives the cylindrical cam 4 at one end thereof to rotate, thereby causing the convex rod 9 to slide along the trajectory of the guide groove 5. Since the straight groove 12 limits the convex rod 9 circumferentially, the convex rod 9 can only drive the round rod 8 to make a left and right reciprocating motion along the trajectory of the guide groove 5. When the round rod 8 moves, it drives the rotating drum 6 to move in the same direction, thereby causing the rotating drum 6 to reciprocate inside the pipe 2. At the same time, since the slide groove 11 limits the square block 10 circumferentially, when the pipe 2 rotates, it also drives the rotating drum 6 to rotate in the same direction through the square block 10. When the quartz sand gradually moves from the pipe 2 to the inside of the rotating drum 6, at this time, the rotation and movement of the rotating drum 6 drive the quartz sand inside the rotating drum 6 to vibrate, thereby reducing the friction between the quartz sand and the inner wall of the rotating drum 6, preventing the quartz sand from accumulating and clogging at the first discharge port 3, thereby facilitating better discharge of the quartz sand.

[0030] Subsequently, the quartz sand after high-temperature calcination falls into the interior of the quartz glass water tank 13 through the second discharge port 7 and the first discharge port 3. The fallen quartz sand is immediately submerged in the quartz glass water tank 13 by a large amount of high-purity water gushing out from the quartz water pipe 14 for water quenching, thereby forming a huge temperature difference of about 1200°C, causing the gas-liquid inclusions in the fine particles of high-purity quartz sand with a particle size range of 0.15-0.05 mm to burst and overflow, thereby achieving the purpose of efficiently removing gas-liquid inclusion impurities in the high-purity quartz sand.

[0031] It is worth noting here that when the existing device is in use, after the quartz sand is water quenched, it is generally salvaged by a hoist installed in the water tank. The two main technical points of this device are to better remove the gas-liquid inclusions in the quartz sand and prevent the quartz sand from accumulating and clogging inside the pipe 2. Therefore, how to rotate the pipe 2, how to drive the quartz sand to move inside it, and how to salvage the quartz sand after it falls into the quartz glass water tank 13 are all existing technologies and are not part of the innovation of this patent.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
