Description

Technical Field

[0001] This utility model relates to the technical field of fused silica processing, and in particular to a feeding device for fused silica production. Background Technology

[0002] Fused silica is a glassy material with special properties, obtained by melting high-purity quartz sand at high temperature and then cooling it into shape. It has high purity, good thermal stability, and stable chemical properties, and is widely used in many fields such as optics, electronics, and semiconductors.

[0003] The raw materials for fused silica processing (such as quartz) are usually in different forms, such as blocks. Directly feeding the blocks of raw materials into subsequent processing equipment (such as heating furnaces, feeding furnaces, etc.) can easily cause blockages inside the equipment, affecting the normal flow of materials and the continuity of the processing flow, due to the varying sizes and potentially large size of the blocks. On the other hand, it is difficult to ensure uniform heating of large blocks of raw materials during heating and other processing, which in turn affects the quality of the final fused silica product. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a feeding device for quartz melting production. This device can effectively crush molten quartz raw materials such as lumps of quartz, avoiding the direct entry of lumpy raw materials into the feeding cylinder, thereby ensuring the smooth progress of subsequent feeding and processing, and preventing problems such as blockage of the feeding cylinder or uneven heating in subsequent processing due to excessively large raw material blocks.

[0006] To achieve the above objectives, this utility model proposes a feeding device for quartz melting production, comprising:

[0007] Feeding bracket;

[0008] A feeding cylinder is inclinedly disposed on the feeding support, and the feeding cylinder is provided with an inlet and an outlet;

[0009] A crushing frame is provided at the inlet of the feeding cylinder. Two sets of crushing shafts are rotatably connected inside the crushing frame.

One end of the crushing shaft is connected to a meshing gear. The two sets of meshing gears are meshed with each other. A crushing motor is connected to the outer wall of the crushing frame. The output end of the crushing motor is meshed with one of the sets of meshing gears.

[0010] A threaded conveyor shaft is provided with helical blades on its outer wall. The threaded conveyor shaft is rotatably connected to the inside of the feeding cylinder. The outer shell of the feeding cylinder is connected to a feeding motor, and the output end of the feeding motor is connected to the threaded conveyor shaft.

[0011] This utility model discloses a feeding device for quartz melting production. This device can effectively crush lumps of quartz and other molten quartz processing raw materials, preventing lumps of raw materials from directly entering the feeding cylinder, thereby ensuring the smooth progress of subsequent feeding and processing, and preventing problems such as blockage of the feeding cylinder or uneven heating in subsequent processing due to excessively large raw material blocks.

[0012] In addition, the feeding device for quartz melting production proposed in the above application may also have the following additional technical features:

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The feeding device for quartz melting production according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, the feeding device for quartz melting production according to an embodiment of this utility model may include:

[0028] Feeding bracket 1.

[0029] The feeding cylinder 2 is inclinedly mounted on the feeding support 1. The feeding cylinder 2 is provided with an inlet 201 and an outlet 202.

[0030] The crushing frame 3 is located at the feed inlet 201 of the feed cylinder 2. Two sets of crushing shafts are rotatably connected inside the crushing frame 3. Several sets of crushing teeth 301 are provided on the surface of the two crushing shafts. The crushing teeth 301 are fixed on both inner walls of the crushing frame 3. One end of the crushing shaft is connected to a meshing gear 302. The two sets of meshing gears 302 are meshed with each other. The outer wall of the crushing frame 3 is connected to a crushing motor. The output end of the crushing motor is meshed with one of the sets of meshing gears 302.

[0031] A threaded conveyor shaft 4 has spiral blades on its outer wall. The threaded conveyor shaft 4 is rotatably connected to the inside of the feeding cylinder 2. The outer shell of the feeding cylinder 2 is connected to a feeding motor 5. The output end of the feeding motor 5 is connected to the threaded conveyor shaft 4. The raw quartz first enters the inside of the crushing frame 3. The crushing motor drives two sets of crushing teeth 301 to rotate. The two sets of meshing crushing teeth 301 rotate in opposite directions. The crushing teeth 301 are staggered. The crushing teeth 301 can crush the quartz blocks and prevent the molten quartz raw material from entering the inside of the feeding cylinder 2. After the raw quartz enters the inside of the feeding cylinder 2, the feeding motor 5 drives the threaded conveyor shaft 4 to rotate. The threaded blades drive the raw quartz to rise and feed the raw quartz into the inside of the heating furnace.

[0032] In one embodiment of this utility model, such as Figures 2-4 As shown, it also includes a feed hopper 6, which is fixed to the feed inlet of the crushing frame 3. The feed inlet of the feed hopper 6 is square, and the square feed inlet of the feed hopper 6 can be adapted to the conveyor belt of the previous station, so as to facilitate the feeding of materials by the conveyor belt.

[0033] As another possible scenario in the embodiment, the feed inlet of the feed hopper 6 is circular. The circular shape facilitates pipeline feeding, and the material flows relatively smoothly when it enters. Since there is no obstruction at the corners, the material flows more naturally and evenly in the circumferential direction, and can better rely on its own gravity or external conveying power to form a stable flow of material into the feed hopper 6.

[0034] In one embodiment of this utility model, such as Figure 5 As shown, it also includes a weighing support 7, which is fixed on the feeding support 1. A weighing scale 8 is installed on the weighing support 7. A conveyor frame is fixed to the weighing surface of the weighing scale 8. A feeding conveyor belt 9 is installed on the inner wall of the conveyor frame. The feeding conveyor belt 9 is located below the discharge port 202 of the feeding cylinder 2. The output end of the feeding conveyor belt 9 is connected to a feeding motor 5. The raw material moves from the discharge port 202 to the top of the weighing scale 8. The raw material of fused silica can also include silicon tetrachloride, alumina and alkali metal oxides, etc. Multiple feeding cylinders 2 can be set for feeding different raw materials. The fused silica processing raw material moves to the top of the weighing scale 8, and the weighing scale 8 weighs it. When the raw material on the weighing scale 8 reaches the preset weight, the feeding conveyor belt 9 is driven to feed the fused silica processing raw material into the feeding furnace.

[0035] In one embodiment of this utility model, such as Figures 2-4 As shown, a rotating shaft is provided on the top surface of the feed hopper 6, and a cover plate 10 is connected to the outer shaft of the rotating shaft. The cover plate 10 is square or round in shape and is used to seal the feed hopper 6.

[0036] Specifically, in actual operation, the crushing tooth 301 can crush the quartz blocks, preventing the molten quartz processing raw material from entering the feeding cylinder 2. After the raw quartz enters the feeding cylinder 2, the threaded blades drive the raw quartz to rise and feed it into the heating furnace. The device can be equipped with multiple feeding cylinders 2 for feeding different raw materials. When the raw material on the weighing scale 8 reaches the preset weight, the feeding conveyor belt 9 is driven to feed a fixed amount of molten quartz processing raw material into the feeding furnace.

[0037] In summary, the feeding device for quartz melting production according to this utility model embodiment can effectively crush molten quartz raw materials such as lumps of quartz, preventing lumps of raw materials from directly entering the feeding cylinder 2, thereby ensuring the smooth progress of subsequent feeding and processing, and preventing problems such as blockage of the feeding cylinder 2 or uneven heating in subsequent processing due to excessively large raw material blocks.
