Description

Technical Field

[0001] This utility model relates to the field of quartz tube production technology, and in particular to a heating device for quartz tube production. Background Technology

[0002] Quartz tubes are a type of special industrial glass made from high-purity silicon dioxide. The production process requires heat treatment. Therefore, a quartz tube heating device, with publication number CN223134325U, is described. In use, the chamber door is opened, and then the toothed plate slides the carrier plate out of the chamber. Next, the pull plate is pulled, and the elastic plate disengages from the slot. The quartz tube is then placed between two sets of inclined support plates, aligning one end of the quartz tube with the other end of the carrier plate. The elastic plate is then inserted into the slot, and the spring telescopic rod pushes against the mounting plate. The V-shaped plate then presses and stabilizes the quartz tube from above. The toothed plate and carrier plate move inwards into the chamber, and the quartz tube is precisely fitted onto the outside of the heating tube.

[0003] However, the patent document mentions that the two sets of elastic plates are respectively set on the front and back of the carrier plate, and each set of elastic plates is fixedly connected to a pull plate on its inner side. Therefore, when removing the top plate to facilitate the placement of the quartz tube, personnel need to sequentially move the locking plates on the front and back to pull out the corresponding elastic plates from the slots. Pulling out one side of the elastic plate alone will cause the entire device to become unbalanced. Therefore, when pulling out the other side of the elastic plate, the overall stability of the device cannot be guaranteed. Moreover, when installing the top plate, at least two people are required to work together to move the pull plates on the front and back to simultaneously insert the two sets of elastic plates into the slots, which is inefficient. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a heating device for quartz tube production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heating device for quartz tube production, comprising a heating box, wherein a horizontally placed heat insulation plate is fixedly installed inside the heating box, and the heating box is divided into an upper cavity and a lower cavity by the heat insulation plate. A base is fixedly installed at the center of the upper surface of the heat insulation plate along the length of the heating box. Several linearly arrayed I-beam wheels are rotatably connected inside the base. Several vertically arranged pneumatic push rods are fixedly installed on both sides of the bottom of the lower cavity. A belt conveyor is fixedly installed at the telescopic ends of several pneumatic push rods located on the same side of the base. The heat insulation plate is hollowed out above each belt conveyor, and a heat insulation strip is inserted into each hollowed-out part on the lower surface of the heat insulation plate. An electric telescopic rod is provided between the heat insulation strip and the bottom surface of the heat insulation plate.

[0006] Preferably, the heating box has several clamping strips evenly distributed along the length of the base on opposite side walls, and sockets are inserted into the surfaces of the clamping strips, with pressure rods for pressing the surface of the quartz tube installed on the sockets.

[0007] Preferably, the side of the clamp strip has several equally spaced oblique holes at its center from top to bottom, the bottom of the oblique holes is inclined downwards and the oblique holes are inserted into the socket.

[0008] Preferably, one side of the clamping strip is hollowed out on both sides of each oblique hole, and the socket is connected to the hollowed-out part on the clamping strip by bolts.

[0009] Preferably, an insulation door is installed on one side of each clamping strip on the wall of the heating box, and an electric push rod is fixedly installed on the outer wall of the heating box at each clamping strip. The telescopic end of the electric push rod passes through the heating box and is fixedly connected to the surface of the adjacent clamping strip.

[0010] Preferably, the telescopic end of the electric push rod is made of tantalum, and the clamp, pressure rod, socket, base and I-beam wheel are all made of high-temperature resistant materials.

[0011] Preferably, a door panel is hinged to one side of the heating box, and a stop bar is fixedly installed on the top of the heating box away from the door panel.

[0012] Preferably, the bottom edge of the clamping strip is slidably connected to the upper surface of the heat insulation board.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up two belt conveyors, with the heat insulation plate surface open, the belt conveyors can easily enter the upper cavity through the heat insulation plate surface open and are higher than the H-beam pulley. Therefore, one end of the quartz tube is put into the heating box along the box opening and overlaps the belt strips of the two belt conveyors. By using the belt parts of the two belt conveyors to move at the same speed, the quartz tube can be automatically and quickly slid into the heating box, which can ensure the quartz tube discharge speed.

[0014] 2. In this utility model, according to the diameter of the quartz tube, the socket is connected to the inclined holes of different heights on the clamping strip, and the socket position is fixed by using bolts to achieve threaded connection of the hollow parts on both sides of the same inclined hole of the socket, thereby fixing the position of the pressure rod. By moving the clamping strip towards the base, the pressure rod set on the clamping strip generates oblique downward pressure on the surface of the quartz tube, and the pressure rods on both sides of the clamping strip can completely fix the quartz tube on the base.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figures 1-4As shown, a heating device for quartz tube production includes a heating chamber 1. The heating chamber 1 achieves temperature rise through a built-in heating wire or a known heating method, thereby heating the quartz tube placed inside the heating chamber 1. A horizontally placed heat insulation plate 13 is fixedly installed inside the heating chamber 1, and the heating chamber 1 is divided into an upper cavity 12 and a lower cavity 11 by the heat insulation plate 13. The quartz tube is placed in the upper cavity 12. A base 9 is fixedly installed at the center of the upper surface of the heat insulation plate 13 along the length direction of the heating chamber 1. Several linearly arrayed heating elements are rotatably connected inside the base 9. The I-beams 10 slide into the quartz tube in the upper cavity 12 and slowly fall to the surface of the I-beams 10 resting in the base 9 for support. Several vertically arranged pneumatic push rods 18 are fixedly installed on both sides of the base 9 at the bottom of the lower cavity 11. A belt conveyor 14 is fixedly installed at the telescopic ends of the pneumatic push rods 18 on the same side of the base 9. The heat insulation plate 13 is perforated above each belt conveyor 14, and a heat insulation strip 16 is inserted into each perforation on the lower surface of the heat insulation plate 13. The heat insulation strip 16 and the heat insulation plate... An electric telescopic rod 15 is installed between the bottom surfaces of the upper cavity 12 and the lower cavity 11. The heat insulation plate 13 and the heat insulation strip 16 separate the upper cavity 12 and the lower cavity 11. Heat insulation materials or other heat insulation methods are used to ensure that the temperatures of the upper cavity 12 and the lower cavity 11 do not interfere with each other, ensuring that the temperature inside the upper cavity 12 does not enter the lower cavity 11. In addition, the retraction of the electric telescopic rod 15 causes the heat insulation strip 16 to slide open, which facilitates the belt conveyor 14 to enter the upper cavity 11 through the hollowed-out area on the surface of the heat insulation plate 13 under the extension and pushing action of the pneumatic push rod 18. In section 2, and above the I-beam 10, when placing the quartz tube, one end of the quartz tube is inserted along the opening of the heating box 1 and overlaps the belt strips of the two belt conveyors 14. By utilizing the same speed of the belt sections of the two belt conveyors 14, the quartz tube can be automatically and conveniently slid into the heating box 1. Then, the two belt conveyors 14 descend so that the quartz tube rests on the I-beam 10 of the base 9. During the heating process, the belt conveyors 14 are retracted into the lower cavity 11, and the heat insulation strip 16 moves to close the hollow part of the heat insulation plate 13.

[0020] The heating box 1 has several clamping strips 6 evenly distributed along the length of the base 9 on opposite side walls. Sockets 7 are inserted into the surface of the clamping strips 6, and pressure rods 8 for pressing the surface of the quartz tube are installed on the sockets 7. Several equally distributed oblique holes 17 are opened from top to bottom at the center of the side of the clamping strips 6. The bottom of the oblique holes 17 is set downwards and is inserted into the sockets 7. The clamping strips 6 are hollowed out on both sides of each oblique hole 17. The sockets 7 are connected to the hollowed-out parts on the clamping strips 6 by bolts. According to the diameter of the quartz tube, the sockets 7 are inserted into the oblique holes 17 at different heights on the clamping strips 6, and the sockets 7 are fixed in position by threaded connection of the hollowed-out parts on both sides of the same oblique hole 17. This fixes the position of the pressure rods 8. The clamping strips 6 are moved towards the base 9, so that the pressure rods 8 on the clamping strips 6 exert oblique downward pressure on the surface of the quartz tube. The pressure rods 8 on both sides of the clamping strips 6 can completely fix the quartz tube to the base 9. Each clamping strip 6 is equipped with an insulating door 2 on one side of the heating chamber 1. The insulating door 2 allows personnel to easily open and adjust the installation height of the socket 7 on the clamping strip 6. An electric push rod 3 is fixedly installed on the outer wall of the heating chamber 1 at each clamping strip 6. The telescopic end of the electric push rod 3 passes through the heating chamber 1 and is fixedly connected to the surface of the adjacent clamping strip 6. The telescopic end of the electric push rod 3 is made of tantalum. The clamping strip 6, pressure rod 8, socket 7, base 9, and I-beam wheel 10 are all made of high-temperature resistant materials. The electric telescopic rod 15 drives the corresponding connected clamping strip 6 to move relative to the base 9. The use of tantalum and high-temperature resistant materials to make the telescopic end of the electric telescopic rod 15, the clamping strip 6, pressure rod 8, socket 7, base 9, and I-beam wheel 10 can ensure the stability of use, that is, to ensure that the internal structure will not be damaged during the heating of the quartz tube.

[0021] A door panel 4 is hinged to one side of the heating box 1. A baffle 5 is fixedly installed on the top of the inner box of the heating box 1 away from the door panel 4. The bottom edge of the clamping strip 6 is slidably connected to the upper surface of the heat insulation plate 13. Similarly, the door panel 4 and the baffle 5 are both made of high temperature resistant materials to ensure structural stability. Furthermore, the door panel 4 and the outer wall of the heating box 1 are insulated using known insulation technologies, such as adding insulation cotton.

[0022] The method of using this utility model is as follows: Open the door panel 4, and use the electric telescopic rod 15 to retract and pull the heat insulation strip 16 to slide, thereby opening the hollow part of the heat insulation plate 13. The extension of the pneumatic push rod 18 pushes the belt conveyor 14 through the hollow part on the surface of the heat insulation plate 13 and into the upper cavity 12, and is set higher than the H-beam wheel 10. One end of the quartz tube is placed along the opening of the heating box 1 and overlaps the belt strips of the two belt conveyors 14. By using the belt parts of the two belt conveyors 14 to move at the same speed, the quartz tube can be automatically and conveniently slid into the heating box 1. Then, the two belt conveyors 14 descend, and the quartz tube rests on the H-beam wheel 10 of the base 9. The extension of the electric telescopic rod 15 causes the clamping strip 6 to drive the pressure rod 8 on its surface to move towards the base 9 until the pressure rod 8 presses against the surface of the quartz tube, thereby fixing the quartz tube. During the heating process, the belt conveyor 14 is retracted into the lower cavity 11, and the heat insulation strip 16 moves to close the hollow part of the heat insulation plate 13.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
