Its excellent comprehensive performance has become the basis for its application in the field of high technology, and it is widely used in optics, optoelectronic devices, and microwave dielectric materials. During the preparation of quartz glass, distillation equipment is required to distill and purify the liquid raw materials. During the purification process, the liquid raw materials will enter the reboiler for evaporation. The existing reboiler heat exchange tubes are arranged at a high density. Although the heating area is large, it is easy to cause uneven heating of the glass liquid raw materials.

If they are set as bent tubes, it is inconvenient to clean the bent tubes later. At the same time, the existing heat exchange tubes are all fixed, and the glass liquid raw materials cannot flow, thereby reducing the heating efficiency of the glass liquid raw materials. In addition, the amount of liquid entering the reboiler is different, so the liquid level height formed is also different.

Beneficial Effects
[0012] 1. In the present application, by setting baffle plate 1 and baffle plate 2 to slide inside the shell, the plurality of heat exchange tubes 1 and 2 can be positioned, and hot steam flows inside the baffle plate 1, so the quartz glass liquid raw material can also be heated, thereby increasing the heating area and improving the heating efficiency. At the same time, the sliding baffle plate 1 and baffle plate 2 can promote the flow of the quartz glass liquid raw material, so that the quartz glass liquid raw material is heated more evenly, further improving the heating efficiency.
[0013] 2. In the present application, the heat exchange tubes 1 and 2 are arranged with relatively low density, and they are swung and tilted under the drive of the baffle plate 1. Under the same shell pass, the heat exchange tubes 1 and 2 increase the heat exchange area when tilted, and during subsequent cleaning, the heat exchange tubes 1 and 2 can be in a straight line to facilitate cleaning. On the other hand, the reciprocating swing of the heat exchange tubes 1 and 2 can make the glass liquid raw material flow continuously, so that the glass liquid raw material is heated more evenly and the heating efficiency is higher. At the same time, the height position of the swinging heat exchange tubes 1 and 2 changes, so it can adapt to the heating of glass liquid raw materials with different liquid level heights, and the heating efficiency is higher.
[0014] 3. In the present application, by setting structures such as gears, racks, and air baffles, after slide plates 1 and 2 drive heat exchange tubes 1 and 2 to swing from an inclined state to a horizontal straight state, the steam entering the head cover can drive slide plate 1 to move to stop block 1 and stop block 2 to squeeze each other, so that the slide bar and the rack slide upward and drive the gear to rotate. The rotation of the gear drives the air baffle to rotate through the rotating shaft, thereby reducing the air intake volume or closing the air intake channel, so that the air pressure on the right side of slide plate 1 inside the head cover is reduced, so that slide plate 1 is reset under the drive of spring 2. At this time, the heat exchange tubes 1 and 2 in the horizontal straight state swing to the inclined state again, achieving the effect of driving the heat exchange tubes 1 and 2 to swing back and forth, and at the same time, the air intake volume can be self-controlled, which is more energy-saving.

DETAILED DESCRIPTION
[0017] The application is described in detail below with reference to the accompanying drawings. DETAILED DESCRIPTION
[0018] The present invention provides a quartz glass distillation device, please refer to Figure 1-2 As shown, it includes a tower kettle 1, a reboiler, and a tower cover 2. The tower cover 2 is connected to the top of the tower kettle 1 through a flange. A liquid outlet 5 is provided at the bottom of the tower kettle 1, and two air inlets 4 are provided on the side wall of the tower kettle 1. The reboiler includes a shell 8. Two air outlets 7 are provided on the upper side wall of the shell 8, and a liquid inlet 9 is provided on the bottom side wall of the shell 8. A liquid outlet pipe 6 is connected between the liquid outlet 5 of the tower kettle 1 and the liquid inlet 9 of the shell 8. A reflux pipe 3 is connected between the two air inlets 4 on the side wall of the tower kettle 1 and the two air outlets 7 on the upper side wall of the shell 8. When the quartz glass liquid raw material is distilled and purified, it is distilled and purified in the tower kettle 1. The liquid at the bottom of the tower kettle 1 can enter the shell 8 of the reboiler through the liquid outlet pipe 6 by means of a water pump or a siphon. The quartz glass liquid raw material is heated and evaporated again by the heat exchange component in the reboiler, and the generated gas enters the tower kettle 1 again through the reflux pipe 3 between the air outlet 7 and the air inlet 4.
[0019] A heat exchange assembly and a driving assembly are also provided inside the shell 8 of the reboiler. The heat exchange assembly includes a heat exchange tube 1 40, a heat exchange tube 2 41, a baffle 1 35 and a baffle 2 38. The baffle 1 35 and the baffle 2 38 are both slidably connected at a position near the bottom of the shell 8. The heat exchange assembly is arranged at the lower position of the shell 8 to provide space for the gas after the quartz glass liquid raw material is heated and evaporated.
[0020] Heat exchange tube 1 40 and heat exchange tube 2 41 are rotatably connected, and heat exchange tube 1 40 and heat exchange tube 2 41 are connected to adjacent baffle 1 35 and baffle 2 38 or between adjacent baffle 2 38. The shape formed by heat exchange tube 1 40 and heat exchange tube 2 41 switches back and forth between a straight shape and an inclined shape.
[0021] See also Figure 1-6 and Fig.11Two limit blocks 45 are fixedly connected to the side walls of the baffle plate 1 35 and the baffle plate 2 38. The inner wall of the shell 8 is provided with a groove body (not shown) that slides with the limit blocks 45. The baffle plate 1 35 and the baffle plate 2 38 slide inside the shell 8 through the limit blocks 45 and the groove body. The interior of the baffle plate 1 35 is hollow, and a baffle 44 is fixedly connected at the middle position. The baffle plate 1 35 and the baffle plate 2 38 are provided with square grooves 37 set at equal angles. The baffle plate 1 35 is provided with two. The square groove 37 of the baffle plate 1 35 close to the tower kettle 1 is fixedly connected with a connecting pipe 36, and the connecting pipe 36 is connected to the inside of the baffle plate 1 35. The square groove 37 of the baffle plate 1 35 away from the tower kettle 1 is not provided with a connecting pipe 36. The inner wall of the square groove 37 of the baffle plate 2 38 A slide groove 39 is provided on the shell 8, and a plurality of baffle plates 38 are provided. The plurality of baffle plates 38 are equidistantly distributed between the two baffle plates 1 35. The baffle plates in the prior art usually only play the role of positioning the heat exchange tubes and are all fixedly arranged. The baffle plates 1 35 and 38 in the present application can slide inside the shell 8, which can not only play the role of positioning the plurality of heat exchange tubes 1 40 and heat exchange tubes 2 41, but also hot steam flows inside the baffle plates 1 35, so the quartz glass liquid raw material can also be heated, the heating area is increased, and the heating efficiency is improved. At the same time, the sliding baffle plates 1 35 and 38 can promote the flow of the quartz glass liquid raw material, so that the quartz glass liquid raw material is heated more evenly, further improving the heating efficiency.
[0022] One end of the heat exchange tube 40 is fixedly connected to a hinged plate 402, and the other end is fixedly connected to two brackets 401, and a rotating tube 403 is fixedly connected between the two brackets 401. One end of the heat exchange tube 41 is fixedly connected to a hinged plate 411, and the other end is fixedly connected to two brackets 412, and a rotating tube 413 is fixedly connected between the two brackets 412. There are multiple heat exchange tubes 40, among which the heat exchange tube 40 closest to the tower kettle 1 has an end that is close to the baffle plate 35 and is rotatably connected and connected to the connecting tube 36 through the hinged plate 402. There are multiple heat exchange tubes 41, among which the heat exchange tube 41 farthest from the tower kettle 1 has an end that is close to the right baffle plate 35 and is rotatably connected and connected to the side wall of the square groove 37 of the baffle plate 35 through the rotating tube 413.
[0023] The ends of the remaining heat exchange tubes 40 near the baffle plate 2 38 are rotatably connected and communicated with the rotating tube 2 413 at the ends of the remaining heat exchange tubes 41 near the baffle plate 2 38 through the hinged plate 1 402, and the two ends of the rotating tube 2 413 respectively pass through the two brackets 2 412 to extend to the interior of the slide groove 39 and are slidably connected to the slide groove 39. The ends of all the heat exchange tubes 1 40 and heat exchange tubes 2 41 located between adjacent baffle plates 1 35 and baffle plates 2 38 and between two adjacent baffle plates 2 38 that are close to each other are rotatably connected and communicated with the hinged plate 2 411 on the heat exchange tube 2 41 through the rotating tube 1 403 between the two brackets 1 401 on the heat exchange tube 1 40.
[0024] The heat exchange tubes in the prior art are arranged at a high density. Although the heating area is large, it is easy to cause uneven heating of the glass liquid raw material. Under the same shell pass, the heating area of the heat exchange tubes arranged in a straight line is relatively small. If they are set as elbows, it is inconvenient to clean the elbows later. At the same time, the existing heat exchange tubes are all fixed and cannot make the glass liquid raw material flow, thereby reducing the heating efficiency of the glass liquid raw material. In addition, the amount of liquid entering the reboiler is different, so the liquid level height formed is also different. The fixed heat exchange tubes cannot adapt to the rapid heating of glass liquids with different liquid level heights. After the steam in the present application enters the baffle 35 closest to the tower kettle 1, according to The liquid flows between multiple heat exchange tubes 1 40 and 2 41 for the first time, and all heat exchange tubes 1 40 and 2 41 are not connected to the baffle 2 38. Finally, the liquid in all heat exchange tubes 1 40 and 2 41 flows into the baffle 1 35 farthest from the bottom of the tower 1. When the two baffles 1 35 slide towards or away from each other, all heat exchange tubes 1 40 and 2 41 can be straightened or rotated and tilted. In this way, all heat exchange tubes 1 40 and 2 41 will continuously swing and drive the baffle 2 38 to slide, thereby further accelerating the flow of the glass liquid raw material and improving the heating efficiency.
[0025] On the one hand, the arrangement density of the heat exchange tube 1 40 and the heat exchange tube 2 41 of the present application is relatively low, and can be tilted under the drive of the baffle 1 35. Under the same shell pass, compared with the heat exchange tubes arranged in a straight line in the prior art, the tilted heat exchange tube 1 40 and the heat exchange tube 2 41 increase the heat exchange area, and during subsequent cleaning, the heat exchange tube 1 40 and the heat exchange tube 2 41 can be in a straight line, which is convenient for cleaning. On the other hand, the reciprocating swing of the heat exchange tube 1 40 and the heat exchange tube 2 41 can make the glass liquid raw material flow continuously, so that the glass liquid raw material is heated more evenly and the heating efficiency is higher. At the same time, the height position of the swinging heat exchange tube 1 40 and the heat exchange tube 2 41 changes, so it can adapt to the heating of glass liquid raw materials with different liquid level heights, and the heating efficiency is higher.
[0026] The baffle 44 divides the cavity inside each baffle 1 35 and baffle 2 38 into equal parts. Hooks 42 are provided on the heat exchange tubes 1 40 and 41 located below the baffle 44 and at the bottom of the baffles 1 35 and 38. Hooks 42 are also provided at the corresponding positions of the baffles 1 35 and 38. Light springs 43 are movably connected to the hooks 42. The two ends of the light springs 43 are movably connected to the hooks 42 at the corresponding positions of the baffles 1 35, 38 and the heat exchange tubes 1 40 and 41, respectively. Since the heat exchange assembly is arranged near the bottom of the shell 8 The heat exchange tubes 1 40 and 41 at the bottom are in the position, so the heat exchange tubes 1 40 and 41 near the lower end of the shell 8 are easy to interfere with the inner wall of the shell 8 when swinging. Because the two heat exchange tubes 1 40 and 41 at the bottom have two swinging directions when swinging, they may swing upward or downward. Therefore, the tension of the light spring 43 can control the heat exchange tubes 1 40 and 41 at the lower end to swing only upward, and under the action of the light spring 43, the heat exchange tubes 1 40 and 41 here can also vibrate slightly when swinging, thereby further accelerating the flow of the glass liquid raw material and improving the heating efficiency.

The elastic seal 28 has a certain elasticity, which is used to ensure the sealing of the diverter pipe 18 and the air outlet pipe 20 when they slide between the sealing plate 55 and the sealing of the collector pipe 46 when it slides in the transfer cover 54.

Two springs 24 are provided at the bottom of the rack 26. The other end of the spring 24 is fixedly connected to the outer wall of the head cover 11. The bottom of the rack 26 is located at the middle position of the two springs 24 and is also fixedly connected to a slide bar 14. The other end of the slide bar 14 penetrates the head cover 11 and extends to the inside of the head cover 11 and is slidably connected to the head cover 11. The end of the slide bar 14 inside the head cover 11 is fixedly connected to a stop block 2 34, and the stop block 2 34 is also provided with an inclined surface.
[0029] At this time, the distance between the two baffle plates 135 of the diverter pipe 18 and the converging pipe 46 is the shortest under the action of the corresponding spring 2 30 and spring 3 48. At this time, the heat exchange tube 1 40 and the heat exchange tube 2 41 are in a tilted state. When the steam enters the upper air cavity 12 through the air intake pipe 17, the diameter of the air intake pipe 17 is larger than the diameter of the diverter pipe 18, and the diverter plate 29 on the diverter pipe 18 will also reduce the air intake flow of the diverter pipe 18. Therefore, while the steam is being transported to the diverter pipe 18, it will gradually fill the space on the right side of the slide plate 32, thereby pushing the slide plate 32 to move to the left, driving the diverter pipe 18 and the baffle plate 35 close to the head cover 11 to slide.
[0030] See also Figure 7 The driving assembly also includes a transfer cover 54, a slide plate 51, a spring 3 48 and a connecting frame 49. The slide plate 51 is slidably connected to the inside of the transfer cover 54. The side of the slide plate 51 close to the head cover 11 is fixedly connected to the connecting frame 49. The other end of the connecting frame 49 is fixedly connected to the manifold 46. The other end of the manifold 46 passes through the transfer cover 54 and extends to the outside to be fixedly connected to the baffle plate 35 close to the transfer cover 54. The manifold 46 is slidably connected to the transfer cover 54. The spring 3 48 is fixedly connected between the slide plate 51 and the inner side wall of the transfer cover 54. A diverter plate 2 52 is provided inside the end of the manifold 46 facing the transfer cover 54.
[0031] At this time, the steam flows through the upper cavity of the baffle 44 in the baffle 1 35, and then flows through all the heat exchange tubes 1 40 and 2 41 above the baffle 44, and then converges to the inside of the baffle 1 35 farthest from the head cover 11, and flows into the manifold 46 from the cavity above the baffle 44 inside the baffle 1 35, and the diverter plate 2 52 in the manifold 46 also diverts the airflow flowing through the manifold 46, and the transverse plate portion of the diverter plate 2 52 divides the flow path of the manifold 46 into two, that is, the airflow flowing into the manifold 46 flows from above the transverse plate portion of the diverter plate 2 52 into the transfer cover 54, and the airflow flowing out of the transfer cover 54 flows from the vertical plate portions below the transverse plate portion of the diverter plate 2 52 to form The steam flows out of the cavity. Since the steam inflow is greater than the outflow, the air pressure inside the space on the left side of the slide plate 51 will gradually increase, thereby driving the slide plate 51 to move to the right. At this time, the slide plates 1 32 and 51 will drive the corresponding baffle plates 1 35 to slide away from each other by driving the diverter pipe 18 and the collector pipe 46, thereby driving each heat exchange tube 1 40 and the heat exchange tube 2 41 to swing, forming a horizontal straight line state, realizing the swing of the heat exchange tube 1 40 and the heat exchange tube 2 41, and realizing the switching of the shape, thereby accelerating the flow speed of the quartz glass liquid raw material, and can adapt to liquid levels of different heights, so that the quartz glass liquid raw material is heated more evenly, the heating efficiency is higher, and it is convenient for subsequent cleaning.
[0032] Further, when the slide plate 1 32 continues to move, after moving a certain distance, until the inclined surface of the stop block 1 33 on it contacts the inclined surface of the stop block 2 34, the stop block 1 33 and the stop block 2 34 squeeze each other, thereby driving the slide bar 14 to move upward, and the slide bar 14 drives the rack 26 to slide upward. Since the rack 26 is meshed with the gear 25, it will drive the gear 25 to rotate. The gear 25 drives the air blocking plate 27 to rotate through the rotating shaft 16, thereby reducing the intake amount of the intake pipe 17 or closing the intake channel of the intake pipe 17, and the steam and condensed liquid inside the reboiler are discharged from the exhaust pipe 21. The internal air pressure of the space between the right side of slide plate 1 32 and the head cover 11 gradually decreases, and the internal air pressure of the space between the left side of slide plate 2 51 and the tail cover 54 also gradually decreases. Therefore, under the action of spring 2 30 and spring 3 48, slide plate 1 32 and slide plate 2 51 slide close to each other, so that heat exchange tube 1 40 and heat exchange tube 2 41 swing to an inclined state. On the one hand, the above technical solution allows steam to heat the glass liquid raw material, on the other hand, it can drive heat exchange tube 1 40 and heat exchange tube 2 41 to swing back and forth, and on the other hand, it can also realize automatic control of air intake, which is more energy-saving.
[0033] See also Figure 2 , Figure 7 , Fig. 9As shown, a weir plate 50 is provided inside the shell 8 between the transfer cover 54 and the tail cover 10, a plurality of through holes 47 are provided on the weir plate 50, and a fixing block 53 is fixedly connected to the side wall of the weir plate 50, and a fixing groove (not shown) which is slidably matched with the fixing block 53 is provided on the inner wall of the shell 8, and a liquid level gauge 15 is also fixedly connected to the outer wall of the shell 8, and a vacuum insulation layer 19 is also fixedly connected to the side wall of the manifold 46 located inside the transfer cover 54, and the other end of the vacuum insulation layer 19 is fixedly connected to the inner wall of the transfer cover 54, and an elastic seal 28 is also provided inside the vacuum insulation layer 19, one end of the elastic seal 28 is bonded to the outer wall of the manifold 46, and the other end of the elastic seal 28 is bonded to the inner wall of the transfer cover 54.
[0034] Working principle: The glass liquid raw material is distilled and purified in the tower kettle 1, and the liquid at the bottom of the tower kettle 1 enters the shell 8 of the reboiler through the liquid outlet pipe 6 for reheating and evaporation, and the external steam enters the upper air cavity 12 inside the head cover 11 through the air inlet pipe 17. At the beginning, the heat exchange tube 1 40 and the heat exchange tube 2 41 are in an inclined state under the action of the spring 2 30 and the spring 3 48. When the steam enters the upper air cavity 12, due to the action of the diverter plate 1 29, the steam inflow is greater than the outflow, and the air pressure in the upper air cavity 12 gradually increases, pushing the slide plate 1 32 to move to the left. At the same time, the steam flows through the baffle plate 1 35, the heat exchange tube 1 40 and the heat exchange tube 2 41, and flows into the baffle plate 1 35 farthest from the tower kettle 1, and then enters the confluence pipe 46. In the process of steam circulation, the glass liquid raw material is heated by the baffle plate 1 35, the heat exchange tube 1 40 and the heat exchange tube 2 41, and the gas generated by the heating and evaporation is heated. The steam enters the interior of the tower kettle 1 through the reflux pipe 3 and flows into the air flow in the manifold 46. Since the steam inflow is greater than the outflow, the air pressure inside the space on the left side of the slide plate 2 51 will gradually increase, thereby driving the slide plate 2 51 to move to the right, thereby driving the baffle plates 1 35 on both sides to slide away from each other, thereby driving the heat exchange tube 1 40 and the heat exchange tube 2 41 to swing, so that the heat exchange tube 1 40 and the heat exchange tube 2 41 swing to a horizontal straight line state. During this process of the heat pipe 1 40 and the heat exchange tube 2 41, the glass liquid raw material can be continuously moved, so that the glass liquid raw material is heated more evenly, thereby improving the heating efficiency of the glass liquid raw material. The steam then flows out from the bottom of the horizontal plate part of the diverter plate 2 52 in the manifold 46, passes through the heat exchange tube 1 40 and the heat exchange tube 2 41 under the baffle 44, and flows into the lower air cavity 23 of the head cover 11 again, and is finally discharged from the exhaust pipe 21.

Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
