[0002] Quartz products are widely used in various fields of life. Quartz products including quartz glass, quartz cups, etc. can improve people's lives. After quartz is produced, it generally needs to be annealed to eliminate internal stress.

[0003] When an existing annealing furnace performs annealing on a quartz product, the quartz product is generally placed on a placement rack in the annealing furnace to heat the quartz product. The annealing furnace generally relies on heat transfer to transfer the heat located on its inner wall or the surrounding area to the entire furnace. This may cause the quartz product placed at the center of the placement rack to be heated slower and the heat transfer to be slower, resulting in uneven heating, which in turn affects the annealing effect of the installed quartz product and reduces the practicality of the quartz furnace. Utility Model Content

The quartz product is displaced during the rotation process, so that all directions of the quartz product can be heated by the heating rod, thereby ensuring uniform heating, thereby ensuring the annealing effect of the quartz product, and thereby increasing the practicality of the vertical quartz furnace. It solves the problem that when the existing annealing furnace anneals the quartz product, the quartz product is generally placed on a placement rack in the annealing furnace to heat the quartz product, and the annealing furnace generally relies on heat transfer to transfer the heat located on its inner wall or the surrounding inside to the entire furnace, which may cause the quartz product placed at the center of the placement rack to be heated slower and the heat transfer to be slower, thereby causing uneven heating, thereby affecting the annealing effect of the quartz product installed, and thereby reducing the practicality of the quartz furnace.

[0043] Furthermore, a worm 8 is fixedly sleeved on the outer surface of the rotating shaft 7;

[0044] The outer surface of the support shaft 3 is fixedly sleeved with a worm gear 9, which is meshed and connected with the worm 8;

[0045] Among them, a push block 10 is fixedly connected to the outer surface of the rotating shaft 7;

[0048] Wherein, a heat conducting plate 16 is provided on the heating rod 15;

[0050] A mainspring 11 is disposed on the positioning shaft 12 , and an inner end of the mainspring 11 is fixedly connected to the positioning shaft 12 .

[0051] Furthermore, a mounting block 17 is fixedly connected to the bottom wall of the furnace body 1, and the outer end of the clockwork spring 11 is fixedly connected to the mounting block 17;

[0053] A plurality of fixing plates 13 are fixedly connected to the outer surface of the positioning shaft 12 .

[0054] Furthermore, when in use, the quartz product is placed on the placement mesh plate 4, and then the furnace door 2 is closed to anneal the quartz product. At this time, the motor 6 is started synchronously, and the motor 6 starts to drive the rotating shaft 7 to rotate, and then synchronously drives the worm 8 to rotate, and then synchronously drives the worm wheel 9, the support shaft 3, the placement mesh plate 4 and the baffle 5 to rotate. During the rotation process, the quartz product placed on the placement mesh plate 4 is synchronously driven to rotate. During the rotation process, the position of the quartz product is displaced, so that all directions of the quartz product can be heated by the heating rod 15, thereby ensuring uniform heating, thereby ensuring the annealing effect of the quartz product, and thereby increasing the practicality of the vertical quartz furnace.

[0055] Furthermore, in this solution, the motor 6 starts to drive the rotating shaft 7 and the positioning shaft 12 to rotate very smoothly, thereby preventing the quartz product from falling from the placement screen 4, thereby ensuring the stability of the vertical quartz furnace.

[0056] Furthermore, in the present invention, the supporting shaft 3, the placement screen plate 4, the baffle 5, the rotating shaft 7, the worm 8, the worm wheel 9, the pushing block 10, the clockwork 11, the positioning shaft 12, the fixing plate 13, the connecting block 14, the mounting block 17, etc. are all made of high temperature resistant materials.

[0057] Furthermore, in the initial state, the connecting block 14 is not in contact with the pushing block 10. When the rotating shaft 7 rotates, the pushing block 10 is synchronously driven to rotate. During the rotation of the pushing block 10, the pushing block 10 contacts the connecting block 14 and pushes the connecting block 14 to rotate around the positioning shaft 12, thereby synchronously driving the positioning shaft 12 to rotate. During the rotation of the positioning shaft 12, the mainspring 11 is driven to shrink and deform, and during the rotation of the positioning shaft 12, the fixed plate 13 is driven to rotate. When the pushing block 10 rotates to no longer contact with the connecting block 14, the positioning shaft 12 is driven to rotate in the opposite direction to the initial state under the action of the released elastic force of the mainspring 11, and then the fixed plate 13 is driven to reciprocate once for each rotation of the rotating shaft 7, so that the fixed plate 13 can fan the air in the furnace body 1, thereby increasing air circulation, accelerating the spread of hot air, and thereby making the quartz product heated more evenly, further ensuring the annealing effect of the quartz product, and thereby increasing the practicality of the vertical quartz furnace.

[0058] Furthermore, a seal is provided between the rotating shaft 7 and the furnace body 1 to prevent hot air from flowing out;

[0059] Furthermore, the supporting shaft 3 , the rotating shaft 7 and the positioning shaft 12 are all rotatably connected to the furnace body 1 via bearings.

[0060] Working principle: when the device is used, the quartz product is placed on the placement screen 4, and then the furnace door 2 is closed to anneal the quartz product. At this time, the motor 6 is started synchronously, and the motor 6 starts to drive the rotating shaft 7 to rotate, and then synchronously drives the worm 8 to rotate, and then synchronously drives the worm wheel 9, the support shaft 3, the placement screen 4 and the baffle 5 to rotate. During the rotation process, the quartz product placed on the placement screen 4 is synchronously driven to rotate. During the rotation process, the position of the quartz product is displaced, so that all directions of the quartz product can be heated by the heating rod 15, thereby ensuring uniform heating, thereby ensuring the annealing effect of the quartz product, and thereby increasing the practicality of the vertical quartz furnace.

[0061] In the initial state, the connecting block 14 is not in contact with the pushing block 10. When the rotating shaft 7 rotates, the pushing block 10 is synchronously driven to rotate. During the rotation of the pushing block 10, the pushing block 10 contacts the connecting block 14 and pushes the connecting block 14 to rotate around the positioning shaft 12, thereby synchronously driving the positioning shaft 12 to rotate. During the rotation of the positioning shaft 12, the mainspring 11 is driven to shrink and deform, and during the rotation of the positioning shaft 12, the fixed plate 13 is driven to rotate. When the pushing block 10 rotates to no longer contact with the connecting block 14, the positioning shaft 12 is driven to rotate in the opposite direction to the initial state under the action of the released elastic force of the mainspring 11, and then the fixed plate 13 is driven to reciprocate once for each rotation of the rotating shaft 7, so that the fixed plate 13 can fan the air in the furnace body 1, thereby increasing air circulation, accelerating the spread of hot air, and thereby making the heating of the quartz product more uniform, further ensuring the annealing effect of the quartz product, and thereby increasing the practicality of the vertical quartz furnace.

[0062] 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.
