Description

Technical Field

[0001] This invention belongs to the field of melting furnace technology, and particularly relates to a melting furnace for producing fused silica. Background Technology

[0002] A melting furnace is an industrial device used to melt materials such as metals, ores, and glass. It heats solid materials to a molten state through high temperatures, enabling subsequent smelting, casting, purification, or processing. Its core function is to provide sufficient heat to overcome the latent heat of fusion of the material, thus achieving the transformation of the material from a solid to a liquid state. In the melting process of quartz, it is generally melted into a liquid using a melting furnace. Molten quartz has good high-temperature resistance, chemical stability, and a low coefficient of expansion, and is widely used in glass manufacturing, ceramic glazes, refractory materials, semiconductor industry, and other fields.

[0003] During the quartz melting process, the quartz reaches a high temperature after melting, and the inductor or melting tank used for melting still retains a certain residual heat after cooling. Traditional receiving boxes are placed close to the inductor for easy material receiving, which makes it easy for operators to be injured by the residual heat of the inductor or melting tube when handling and moving the material, thus affecting the operation. Summary of the Invention

[0004] The purpose of this invention is to provide a melting furnace for the production of fused silica, in order to solve the problem that the residual heat of the melting tank or inductor after melting will affect the handling of materials.

The mounting shaft is rotatably connected to the inner wall of the connecting pipe provided on one side of the tank, and the plug rod is slidably connected to the connecting pipe through a groove opened in the inner wall of the connecting pipe.

[0013] As a further description of the above technical solution:

One end of the mounting shaft is provided with a pipe, and the pipe is connected to the main body. One end of the mounting shaft is fixedly connected to one end of the second connecting rod.

[0015] As a further description of the above technical solution:

[0016] The sealing assembly includes a sealing cover, one end of which is fitted with a mounting base. A sealing block is rotatably mounted on the mounting base via a groove formed inside. A sleeve is installed inside the sealing block, and a mounting rod is slidably mounted on the inner wall of the sleeve.

[0017] As a further description of the above technical solution:

[0018] A stop bar is installed at one end of the mounting rod, a knob is installed at the other end of the mounting rod, a mounting block is installed at one end of the sleeve, and a rack is installed on one side of the mounting base.

[0019] As a further description of the above technical solution:

[0020] A toothed plate is slidably installed in the groove opened in the mounting block. A lever is installed on one side of the toothed plate, and a first spring is installed on one side of the lever. The lever is slidably connected to the mounting block through the groove opened in the mounting block.

[0021] As a further description of the above technical solution:

[0022] The sealing plate at one side of the opening of the tank body has a groove corresponding to the stop bar. One end of the sleeve and one end of the knob have corresponding arc-shaped blocks. The toothed plate is engaged with the rack.

[0023] As a further description of the above technical solution:

[0024] One end of the sealing cap is hinged to the sealing plate provided at the opening on one side of the tank body. The outer wall of the sealing block is provided with a notch, and the outer wall of the mounting base is provided with a through hole communicating with the outside. The mounting base and the sealing cap are provided with vent holes communicating with the inside of the tank body.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In this invention, by incorporating a receiving assembly, during melting, quartz raw material is placed into the melting tank, the sealing cap is closed, and the internal environment of the tank is adjusted using a vacuum module within the main body. This allows for heating via an inductor coil, thereby melting the quartz inside the melting tank. After melting, rotating the mounting shaft causes the inductor coil and the melting tank to rotate. During this rotation, the mounting shaft drives the second connecting rod to rotate, which in turn drives the first connecting rod to move. This movement of the movable seat on the sliding plate surface, via the connection between the connecting column and the connecting sleeve, moves the receiving trough to a suitable position, allowing the molten quartz to enter the receiving trough. When the melting tank is tilted and reset, the reset of the melting tank, via the first and second connecting rods, causes the movable seat to reset. During the reset of the movable seat, the wedge blocks... The material is inserted into the movable base and contacts the receiving groove, thereby lifting the receiving groove by the wedge, facilitating its removal from the tank. This design allows the movable base to move via the first and second connecting rods when pouring molten quartz, moving the receiving groove to the appropriate position. This ensures accurate pouring of the raw material into the receiving groove during pouring. After pouring, the movable base returns to its original position under the action of the first and second connecting rods. When the movable base and receiving groove contact the wedge, the wedge lifts the receiving groove, facilitating its removal from the tank and keeping it away from the inductor coil and the receiving groove. This prevents residual heat from affecting the removal of the receiving groove, and the wedge further reduces the impact of residual heat on its removal.

[0027] 2. In this invention, by incorporating a tilting assembly, after the quartz raw material has been melted, pressing the pressure rod moves the insert rod, causing it to retract into the mounting shaft and separate from the connecting pipe on one side of the tank. Simultaneously, the second spring is compressed, which in turn pulls the pressure rod and drives the mounting shaft to rotate via the sliding sleeve. This rotation of the mounting shaft causes the inductor coil and the melting tank to rotate, thus completing the tilting process. During resetting, rotating the mounting shaft to a certain position releases the pressure rod, and under the action of the second spring, the insert rod extends again and re-inserts into the tank. The rod is fixed in the groove inside the side connecting pipe. This design allows the insert rod to be separated from the inner wall of the connecting pipe on one side of the tank by pressing the pressure rod after melting. Then, by moving the pressure rod and the sliding sleeve, the mounting shaft is rotated, which in turn drives the inductor and the melting tank to rotate, thus completing the pouring of the raw material into the receiving trough. After pouring, the mounting shaft is reset and the insert rod can be reinserted into the groove on the inner wall of the connecting pipe by the second spring, thus fixing the mounting shaft and preventing it from rotating during the melting process and affecting the melting process.

[0028] 3. In this invention, a sealing assembly is provided inside. After adding raw materials, rotating the knob drives the mounting rod and the stop rod to rotate, causing the stop rod to align with the groove in the sealing plate on one side of the tank. This pushes the sealing cover to close the opening on one side of the tank, allowing the stop rod to pass through the opening in the sealing plate. Then, rotating the knob makes the stop rod perpendicular to the opening. Rotating the mounting block drives the sleeve and the sealing block to rotate, thereby sealing the vent hole in the mounting base through the sealing block. Simultaneously, the compression between the sleeve and the arc-shaped block on the knob side allows the sealing cover to be tightly connected to the opening on one side of the tank for sealing. The sleeve is also fixed by the meshing between the toothed plate and the rack. When opening the sealing cover, pushing the lever... The rod separates the toothed plate from the rack, causing the mounting block to rotate and drive the sleeve and sealing block to rotate as well. This aligns the opening of the sealing block with the vent hole inside the mounting base, allowing air to pass through the opening on the outer wall of the mounting base to the inside of the tank. This facilitates opening the sealing cap. This design ensures the tank is sealed by blocking the vent hole inside the mounting base when sealing the tank. When opening the sealing cap, the rotation of the sealing block allows the vent hole inside the mounting base to connect with the outside, maintaining constant pressure inside the tank and facilitating opening the sealing cap. Furthermore, when sealing the cap, the pressure between the sleeve and the arc-shaped block at one end of the knob further seals the cap, ensuring both the tank's airtightness and the vacuum inside the tank.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-8The present invention provides a technical solution: a smelting furnace for producing fused silica, comprising a main body 1, a tank 2 mounted on the top surface of the main body 1, a top cover 4 mounted on the top of the tank 2; a tilting assembly 5 installed inside the tank 2; a receiving assembly 6 installed inside the tank 2 and located on one side of the tilting assembly 5; and a sealing assembly 3 installed on one side of the tank 2.

[0041] The receiving assembly 6 includes a sliding plate 64, a movable seat 62 slidably mounted on the top surface of the sliding plate 64, a receiving groove 61 on the top surface of the movable seat 62, a wedge 63 mounted on the top surface of the sliding plate 64, a connecting sleeve 65 mounted on one side of the movable seat 62, a connecting column 66 rotatably mounted inside the connecting sleeve 65, a first connecting rod 67 mounted on one end of the connecting column 66, a second connecting rod 68 rotatably mounted on the other end of the first connecting rod 67, a groove corresponding to the wedge 63 opened on one side of the movable seat 62, an angle corresponding to the inclined surface of the wedge 63 at the bottom end of the receiving groove 61, and the bottom surface of the sliding plate 64 fixedly connected to the bottom surface of the tank body 2.

[0042] The specific implementation is as follows: During melting, quartz raw material is placed into the melting tank 51, and the sealing cover 31 is closed. The environment inside the tank 2 is adjusted by the vacuum module in the main body 1, etc., so that the quartz inside the melting tank 51 is melted by heating through the inductor coil 52. After melting is completed, the inductor coil 52 and the melting tank 51 are rotated by rotating the mounting shaft 53. During the rotation of the mounting shaft 53, the mounting shaft 53 can drive the second connecting rod 68 to rotate, and the second connecting rod 68 can drive the first connecting rod 67 to move, thereby connecting the column 66. The connection between the connecting sleeve 65 and the movable seat 62 moves on the surface of the slide plate 64, thereby moving the receiving groove 61 to a suitable position, allowing the molten quartz to enter the receiving groove 61. When the pouring is completed and the melting tank 51 is reset, the reset of the melting tank 51 can drive the movable seat 62 to reset through the first connecting rod 67 and the second connecting rod 68. During the reset process of the movable seat 62, as the wedge 63 is inserted into the movable seat 62 and contacts the receiving groove 61, the wedge 63 lifts the receiving groove 61, making it easy to remove the receiving groove 61 from the inside of the tank body 2.

[0043] The tilting assembly 5 includes a mounting shaft 53, an inductor 52 mounted at one end of the mounting shaft 53, a melting tank 51 disposed inside the inductor 52, a sealing ring 54 mounted on the outer wall of the mounting shaft 53, a sliding sleeve 58 mounted at one end of the mounting shaft 53, a pressure rod 56 slidably mounted inside the sliding sleeve 58, an insertion rod 55 mounted at the bottom end of the pressure rod 56, a second spring 57 mounted at the bottom end of the insertion rod 55, the mounting shaft 53 being rotatably connected to the inner wall of a connecting pipe provided on one side of the tank body 2, and the insertion rod 55 being slidably connected to the connecting pipe through a groove opened in the inner wall of the connecting pipe, the sealing ring 54 being rotatably connected to the connecting pipe through a groove opened in the inner wall of the connecting pipe provided on one side of the tank body 2, a pipe provided at one end of the mounting shaft 53, and the pipe being connected to the main body 1, and one end of the mounting shaft 53 being fixedly connected to one end of a second connecting rod 68.

[0044] The specific implementation is as follows: After the quartz raw material is melted, the insert rod 55 can be moved by pressing the pressure rod 56, so that the insert rod 55 retracts into the mounting shaft 53 and separates from the connecting pipe on one side of the tank body 2. At the same time, the second spring 57 is compressed, and then the pressure rod 56 is pulled and the mounting shaft 53 is rotated through the sliding sleeve 58. The rotation of the mounting shaft 53 drives the inductor coil 52 and the melting tank 51 to rotate, thereby completing the tilting. When resetting, the mounting shaft 53 is rotated to a certain position, thereby releasing the pressure rod 56 and causing the insert rod 55 to extend again under the action of the second spring 57, and the insert rod 55 is reinserted into the groove in the connecting pipe on one side of the tank body 2, thereby completing the fixation.

[0045] The sealing assembly 3 includes a sealing cover 31, with a mounting base 32 installed at one end of the sealing cover 31. A sealing block 33 is rotatably mounted on the mounting base 32 through an internal groove. A sleeve 38 is installed inside the sealing block 33, and an mounting rod 34 is slidably mounted on the inner wall of the sleeve 38. A stop bar 35 is installed at one end of the mounting rod 34, and a knob 39 is installed at the other end. A mounting block 37 is installed at one end of the sleeve 38. A rack 312 is installed on one side of the mounting base 32. A toothed plate 310 is slidably mounted in the groove of the mounting block 37. A lever 36 is installed on one side of the toothed plate 310. A first spring 311 is installed on one side of the lever 36. The lever 36 is slidably connected to the mounting block 37 through a groove opened in the mounting block 37. A groove corresponding to the stop bar 35 is opened on one side of the sealing plate at the opening on one side of the tank body 2. One end of the sleeve 38 and one end of the knob 39 are provided with corresponding arc-shaped blocks. The toothed plate 310 is meshed with the rack 312. One end of the sealing cover 31 is hinged to the sealing plate at the opening on one side of the tank body 2. The outer wall of the sealing block 33 is provided with a notch, and the outer wall of the mounting base 32 is provided with a through hole communicating with the outside. Ventilation holes communicating with the inside of the tank body 2 are opened in the mounting base 32 and the sealing cover 31.

[0046] The specific implementation is as follows: After adding raw materials, rotating the knob 39 drives the mounting rod 34 and the stop rod 35 to rotate, so that the stop rod 35 corresponds to the groove opened in the sealing plate on one side of the tank body 2, thereby pushing the sealing cover 31 to close the opening on one side of the tank body 2, and allowing the stop rod 35 to pass through the opening of the sealing plate. Then, rotating the knob 39 makes the stop rod 35 perpendicular to the opening. Then, rotating the mounting block 37 drives the sleeve 38 and the sealing block 33 to rotate, thereby sealing the vent hole in the mounting base 32 through the sealing block 33, and at the same time, it enables the sleeve 38 and the knob 34 to rotate. The compression between the arc-shaped blocks on one side of the 9 allows the sealing cover 31 to be tightly connected to the opening on one side of the tank body 2 for sealing. At the same time, the sleeve 38 can be fixed by the meshing between the toothed plate 310 and the rack 312. When the sealing cover 31 is opened, the toothed plate 310 and the rack 312 are separated by pushing the lever 36, thereby rotating the mounting block 37 and causing the sleeve 38 and the sealing block 33 to rotate. This makes the opening of the sealing block 33 correspond to the vent hole in the mounting base 32, so that the tank body 2 can be vented through the opening on the outer wall of the mounting base 32, thus making it easy to open the sealing cover 31.

[0047] Working principle: During smelting, quartz raw material is placed into the melting tank 51. Rotating the knob 39 rotates the mounting rod 34 and the stop rod 35, aligning the stop rod 35 with a groove in the sealing plate on one side of the tank body 2. This pushes the sealing cover 31, closing the opening on one side of the tank body 2 and allowing the stop rod 35 to pass through the opening in the sealing plate. Rotating the knob 39 then makes the stop rod 35 perpendicular to the opening. Rotating the mounting block 37 rotates the sleeve 38 and the sealing block 33, sealing the vent hole in the mounting base 32. Simultaneously, the compression between the sleeve 38 and the arc-shaped block on one side of the knob 39 forces the sealing cover 31 to engage with the tank body 2. The opening on one side is tightly connected to achieve a seal, and the sleeve 38 is fixed by the meshing between the toothed plate 310 and the rack 312. Then, the environment inside the tank 2 is adjusted by the vacuum module in the main body 1, so that the inductor coil 52 heats and melts the quartz inside the melting tank 51. After melting is completed, the insert rod 55 can be moved by pressing the pressure rod 56, so that the insert rod 55 retracts into the mounting shaft 53 and separates from the connecting pipe on one side of the tank 2. At the same time, the second spring 57 is compressed, and the pressure rod 56 is pulled and the mounting shaft 53 is rotated through the sliding sleeve 58. The rotation of the mounting shaft 53 drives the inductor coil 52 and the melting tank 51 to rotate, thus... Upon completion of the tilting process, during the rotation of the mounting shaft 53, the mounting shaft 53 drives the second connecting rod 68 to rotate, and the second connecting rod 68 drives the first connecting rod 67 to move. This, through the connection between the connecting column 66 and the connecting sleeve 65, causes the movable seat 62 to move on the surface of the sliding plate 64, thereby moving the receiving trough 61 to a suitable position, allowing the molten quartz to enter the receiving trough 61. When the tilting is complete and the melting tank 51 is reset, the reset of the melting tank 51, via the first connecting rod 67 and the second connecting rod 68, causes the movable seat 62 to reset. During the reset process of the movable seat 62, as the wedge 63 inserts into the movable seat 62 and contacts the receiving trough 61, ... The receiving groove 61 is lifted by the wedge 63, making it easy to remove the receiving groove 61 from the inside of the tank body 2. When resetting, the mounting shaft 53 is rotated to a certain position, thereby releasing the pressure rod 56 and causing the insertion rod 55 to extend again under the action of the second spring 57, and allowing the insertion rod 55 to be reinserted into the groove in the connecting pipe on one side of the tank body 2, thereby completing the fixation. When opening the sealing cover 31, the toothed plate 310 is separated from the rack 312 by pushing the lever 36, thereby rotating the mounting block 37 to drive the sleeve 38 and the sealing block 33 to rotate, so that the opening of the sealing block 33 corresponds to the vent hole in the mounting base 32, thereby allowing air to vent into the inside of the tank body 2 through the opening on the outer wall of the mounting base 32, thus making it easy to open the sealing cover 31.
