Description

Technical Field

[0001] The invention relates to the technical field of glass fibers, in particular to a production device for glass fiber precursors. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of six kinds of minerals, namely pyrophyllite, quartz sand, limestone, dolomite, colemanite, and magnesia stone, through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is from several microns to more than 20 microns, which is equivalent to 1 / 20-1 / 5 of a hair. Each bundle of fiber strands is composed of hundreds or even thousands of single filaments. Glass fiber is usually used as reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy.

[0003] Traditional glass fiber raw yarn production equipment has some disadvantages. First, due to the large volume of block glass, the melting time is slow, resulting in low production efficiency. At the same time, the temperature of the molten glass is uneven, which in turn leads to poor drawing quality.

[0004] Therefore, a glass fiber precursor production device is proposed. Summary of the invention

[0005] The object of the present invention is to provide a glass fiber raw yarn production equipment, which drives the rotating shaft inside the conical cavity to rotate by a motor, and then can transport the larger particles of glass raw materials entering the collecting port, so that they are sent to multiple crushing cutters again, and then they can be crushed again to improve the crushing efficiency of the glass raw materials. After the rotating shaft rotates, it can drive the reciprocating screw inside the reaction chamber to rotate, and the molten raw materials on the inner wall of the reaction chamber can be scraped off to improve the utilization rate of the glass raw materials, while also reducing the difficulty of cleaning the inner wall of the reaction chamber. After the rotating shaft rotates, it can be convenient to blow the fine materials inside the conical cavity to the inside of the reaction chamber, thereby improving the feeding efficiency inside the reaction chamber, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A glass fiber raw yarn production equipment comprises a tank body, a feed box fixedly mounted on the upper end of the tank body, a feed port fixedly mounted on the top of the feed box for feeding glass raw materials, a conical cavity opened inside the feed box for storing glass raw materials, a reaction chamber for heating the glass raw materials, and a wire drawing device for drawing the molten glass raw materials. A motor is fixedly mounted on the top of the feed box, a rotating shaft is fixedly mounted on the output end of the motor, the lower end of the rotating shaft passes through the feed box and extends to the inside of the reaction chamber, a plurality of groups of crushing cutters for crushing the glass raw materials are fixedly mounted on the outer edge of the rotating shaft inside the conical cavity, and the conical cavity is provided with a plurality of crushing cutters for crushing the glass raw materials. Two conveying pipes are symmetrically fixedly installed inside the cavity, and conveying rods are rotatably installed inside the two conveying pipes. The upper ends of the two conveying rods extend to the outside of the feed box and are respectively fixedly installed with second bevel gears. Two rotating rods are symmetrically rotatably installed on the upper end of the feed box, and the outer edges of the two rotating rods are fixedly installed with first bevel gears, which are meshed with the second bevel gears. The two rotating rods are connected to the rotating shafts through two transmission belts respectively, and spiral conveying blades for transporting uncrushed glass raw materials are fixedly installed on the outer edges of the two conveying rods and inside the two conveying pipes, and collecting ports are opened at the bottoms of the two conveying pipes.

[0008] When producing glass raw fibers, the glass raw materials are first put into the conical cavity inside the feed box through the feed port, and then the motor is started. The motor then drives the rotating shaft inside the conical cavity to rotate, and then drives the multiple crushing cutters in the conical cavity to rotate through the rotating shaft, thereby hitting the input glass raw materials to break them into smaller particles for subsequent heating. However, for some larger, large-particle raw materials that are not broken in time, they will enter the interior of the conveying pipe through the collecting port at the bottom of the conveying pipe. At the same time, after the motor is started, the rotating shaft will drive the two rotating rods to rotate through two transmission belts, and then the two rotating rods will respectively drive the conveying rods inside the two second conical gears to rotate through the two first conical gears, and then respectively drive the spiral conveying blades inside the two conveying pipes to rotate, thereby transporting the larger particles of glass raw materials entering the collecting port, so that they are sent to the multiple crushing cutters again, and then they can be crushed again to improve the crushing efficiency of the glass raw materials.

[0009] Preferably, a filter screen for filtering the crushed glass raw materials is fixedly installed at the bottom of the feed box, and a material guide port for facilitating the transportation of the glass raw materials is provided at the bottom of the feed box and the bottom of the tank body below the filter screen.

[0010] Preferably, the filter screen is conical in shape and has a mesh size of 5.

[0011] The crushed glass raw materials can pass through the filter screen into the material guide port, and then into the reaction chamber, and then be heated and melted by the equipment inside the reaction chamber. The melted glass raw materials can be drawn through the drawing equipment.

[0012] Preferably, a reciprocating screw is fixedly installed on the lower end of the rotating shaft inside the reaction chamber, and the outer cylindrical surface of the reciprocating screw is threadedly connected to a screw sleeve, and a plurality of fixed rods are fixedly installed at equal intervals in the external circumferential direction of the screw sleeve, and one end of each of the fixed rods is rotatably installed with two scrapers for scraping the molten material on the inner wall of the reaction chamber.

[0013] Preferably, the rotation angle of the scraper is 0° to 90°.

[0014] Preferably, two limiting grooves are symmetrically provided inside the reaction chamber, wherein one end of the two fixing rods respectively extends into the inside of the two limiting grooves.

[0015] After the rotating shaft rotates, the reciprocating screw inside the reaction chamber can be driven to rotate. Since two of the multiple fixed rods fixed on the outside of the screw sleeve are respectively inserted into the limiting grooves, after the reciprocating screw rotates, the screw sleeve will drive the multiple fixed rods to move up and down inside the reaction chamber, and then the multiple fixed rods will drive the scraper to scrape the material on the inner wall of the reaction chamber. Since the scraper is rotatably installed at one end of the fixed rod, and its rotation angle is 0° to 90°, when the scraper moves up, due to the friction between the inner wall of the reaction chamber and the scraper, the scraper will be in a vertical state. At this time, the molten raw material on the inner wall of the reaction chamber will not be scraped. When the scraper moves down, due to the friction between the reaction chamber and the scraper, the scraper unfolds into a horizontal state and scrapes the molten raw material on the inner wall of the reaction chamber, so as to improve the utilization rate of the glass raw materials and reduce the difficulty of cleaning the inner wall of the reaction chamber.

[0016] Preferably, a circular cavity is also provided at the top of the feed box, a connecting rod is fixedly installed on the outer edge of the rotating shaft inside the circular cavity, a first magnet is fixedly installed on one end of the connecting rod, two strip cavities are also symmetrically provided on the top of the feed box, elastic air bags are fixedly installed inside the two strip cavities, a second magnet that attracts the first magnet is fixedly installed on one end of the two elastic air bags, two air inlet pipes are symmetrically fixedly installed on the upper end of the feed box, and two nozzles are symmetrically fixedly installed on the inner top of the conical cavity.

[0017] Preferably, a one-way valve is fixedly installed between the elastic airbag, the air inlet pipe and the nozzle, the one-way valve at the upper end only allows external gas to enter the interior of the elastic airbag, and the one-way valve at the lower end only allows the gas inside the elastic airbag to enter the interior of the nozzle.

[0018] Preferably, the two nozzles are arranged at an angle.

[0019] After the rotating shaft rotates, it will drive the connecting rod inside the circular cavity to rotate, and then the connecting rod will drive the first magnet to rotate inside the circular cavity. Due to the mutual attraction between the first magnet and the second magnet, when the first magnet and the second magnet are close to each other, the elastic airbag will be pulled to expand through the second magnet, and then the external gas will be drawn into the interior of the strip cavity through the air inlet pipe. After the first magnet and the second magnet are separated, the elastic airbag will spray the gas through the nozzle under the action of its own elastic force. Since the nozzle is inclined and faces the filter, it is convenient to blow the fine material inside the conical cavity to the inside of the reaction chamber, thereby improving the feeding efficiency inside the reaction chamber.

[0020] Preferably, an exhaust pipe is fixedly installed on the top of the tank body, and a pressure valve is fixedly installed inside the exhaust pipe.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The motor can be used to drive the rotating shaft inside the conical cavity to rotate, and then the larger particles of glass raw materials entering the collecting port can be transported to be sent to multiple crushing cutters again, and then they can be crushed again to improve the crushing efficiency of the glass raw materials.

[0023] 2. After the shaft rotates, the reciprocating screw inside the reaction chamber can be driven to rotate, and the molten raw materials on the inner wall of the reaction chamber can be scraped off to improve the utilization rate of the glass raw materials, while also reducing the difficulty of cleaning the inner wall of the reaction chamber.

[0024] 3. After the shaft rotates, the fine materials inside the conical cavity can be blown into the interior of the reaction chamber, thereby improving the feeding efficiency into the reaction chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figures 1 to 8 The present invention provides a glass fiber precursor production equipment, and the technical solution is as follows:

[0038] A glass fiber raw yarn production equipment, including a tank body 1, a feed box 2, fixedly installed at the upper end of the tank body 1, a feed port 32, fixedly installed at the top of the feed box 2, used to put in glass raw materials, a conical cavity 3, opened inside the feed box 2, used to store glass raw materials, a reaction chamber 4, used to heat the glass raw materials, and a wire drawing device 33, used to draw the molten glass raw materials. A motor 5 is fixedly installed on the top of the feed box 2, and a rotating shaft 6 is fixedly installed at the output end of the motor 5. The lower end of the rotating shaft 6 passes through the feed box 2 and extends to the inside of the reaction chamber 4. The outer edge of the rotating shaft 6 is fixedly installed inside the conical cavity 3 with multiple groups of crushing cutters 15 for crushing the glass raw materials. The inside of the conical cavity 3 is fixedly installed with a plurality of crushing cutters 15 for crushing the glass raw materials. There are two fixedly installed conveying pipes 12, and conveying rods 10 are rotatably installed inside the two conveying pipes 12. The upper ends of the two conveying rods 10 extend to the outside of the feed box 2 and are respectively fixedly installed with second bevel gears 11. Two rotating rods 7 are symmetrically rotatably installed on the upper end of the feed box 2. The outer edges of the two rotating rods 7 are fixedly installed with first bevel gears 9, and the first bevel gears 9 are meshed with the second bevel gears 11. The two rotating rods 7 are respectively connected to the rotating shaft 6 through two transmission belts 8. The outer edges of the two conveying rods 10 and the insides of the two conveying pipes 12 are fixedly installed with spiral conveying blades 13 for transporting uncrushed glass raw materials, and the bottoms of the two conveying pipes 12 are provided with collecting ports 14.

[0039] When producing glass strands, the glass raw materials are first put into the conical cavity 3 inside the feed box 2 through the feed port 32, and then the motor 5 is started, and then the motor 5 will drive the rotating shaft 6 inside the conical cavity 3 to rotate, and then the rotating shaft 6 drives the multiple crushing cutters 15 in the conical cavity 3 to rotate, and then the glass raw materials are hit to break them into smaller particles for subsequent heating. However, for some larger particles that are not broken in time, they will enter the interior of the conveying pipe 12 through the collecting port 14 at the bottom of the conveying pipe 12. At the same time, after the motor 5 is started, the rotating shaft 6 will The two transmission belts 8 drive the two rotating rods 7 to rotate, and then the two rotating rods 7 will respectively drive the conveying rods 10 inside the two second bevel gears 11 to rotate through the two first bevel gears 9, and then respectively drive the spiral conveying blades 13 inside the two conveying pipes 12 to rotate, so as to transport the larger particles of glass raw materials entering the collecting port 14. The large particles of glass raw materials are transported to the upper end of the conveying pipe 12 through the spiral conveying blades 13, and fall from the opening at the upper end to the crushing cutter 15, so that they are sent to the multiple crushing cutters 15 again, and then they can be crushed again to improve the crushing efficiency of the glass raw materials.

[0040] As an embodiment of the present invention, refer to Figure 1 A filter screen 16 for filtering the crushed glass raw materials is fixedly installed at the bottom of the feed box 2. A material guide port 17 for transporting the glass raw materials is provided at the bottom of the feed box 2 and the bottom of the tank body 1 below the filter screen 16. The filter screen 16 is conical in shape and has a mesh size of 5.

[0041] The crushed glass raw material can pass through the filter 16 into the inside of the material guide port 17 and then into the inside of the reaction chamber 4 , and then be heated and melted by the equipment inside the reaction chamber 4 . The melted glass raw material can be drawn through the wire drawing equipment 33 .

[0042] As an embodiment of the present invention, refer to Figure 1 and Figure 3-8 A reciprocating screw 18 is fixedly installed at the lower end of the rotating shaft 6 inside the reaction chamber 4. The outer cylindrical surface of the reciprocating screw 18 is threadedly connected to a screw sleeve 19. A plurality of fixed rods 20 are fixedly installed at equal intervals in the circumferential direction of the outer side of the screw sleeve 19. Two scrapers 21 for scraping the molten material on the inner wall of the reaction chamber 4 are rotatably installed at one end of each fixed rod 20. The rotation angle of the scraper 21 is 0° to 90°. Two limit grooves 22 are symmetrically opened inside the reaction chamber 4, and one end of the two fixed rods 20 extends to the inside of the two limit grooves 22 respectively.

[0043] After the rotating shaft 6 rotates, the reciprocating screw 18 inside the reaction chamber 4 can be driven to rotate. Since two of the multiple fixed rods 20 fixed outside the screw sleeve 19 are respectively inserted into the inside of the limit groove 22, after the reciprocating screw 18 rotates, the screw sleeve 19 will drive the multiple fixed rods 20 to move up and down inside the reaction chamber 4, and then the multiple fixed rods 20 will drive the scraper 21 to scrape the material on the inner wall of the reaction chamber 4. Since the scraper 21 is rotatably installed at one end of the fixed rod 20, and its rotation angle is The angle is 0° to 90°, so when the scraper 21 moves up, due to the friction between the inner wall of the reaction chamber 4 and the scraper 21, the scraper 21 will be in a vertical state, and the molten raw material on the inner wall of the reaction chamber 4 will not be scraped off at this time. When the scraper 21 moves down, due to the friction between the reaction chamber 4 and the scraper 21, the scraper 21 unfolds into a horizontal state and scrapes off the molten raw material on the inner wall of the reaction chamber 4, so as to improve the utilization rate of the glass raw materials and reduce the difficulty of cleaning the inner wall of the reaction chamber 4.

[0044] As an embodiment of the present invention, refer to Figure 1-2 A circular cavity 23 is also provided on the top of the feed box 2. A connecting rod 24 is fixedly installed on the outer edge of the rotating shaft 6 inside the circular cavity 23. A first magnet 25 is fixedly installed on one end of the connecting rod 24. Two strip cavities 26 are symmetrically provided on the top of the feed box 2. Elastic air bags 27 are fixedly installed inside the two strip cavities 26. Second magnets 28 that attract each other with the first magnet 25 are fixedly installed on one end of the two elastic air bags 27. Two air inlet pipes 30 are symmetrically fixedly installed on the upper end of the feed box 2. Two nozzles 31 are symmetrically fixedly installed on the inner top of the conical cavity 3.

[0045] As an embodiment of the present invention, refer to Figure 1-2 A one-way valve 29 is fixedly installed between the elastic airbag 27, the air inlet pipe 30 and the nozzle 31. The upper one-way valve 29 only allows external gas to enter the elastic airbag 27, and the lower one-way valve 29 only allows the gas inside the elastic airbag 27 to enter the nozzle 31. Both nozzles 31 are set at an angle.

[0046] After the rotating shaft 6 rotates, it will drive the connecting rod 24 inside the circular cavity 23 to rotate, and then the connecting rod 24 will drive the first magnet 25 to rotate inside the circular cavity 23. Due to the mutual attraction between the first magnet 25 and the second magnet 28, when the first magnet 25 and the second magnet 28 are close to each other, the elastic airbag 27 will be pulled to expand through the second magnet 28, and then the external gas will be drawn into the interior of the strip cavity 26 through the air inlet pipe 30. After the first magnet 25 and the second magnet 28 are separated, the elastic airbag 27 will spray the gas through the nozzle 31 under the action of its own elastic force. Since the nozzle 31 is inclined and faces the filter 16, it is convenient to blow the fine materials inside the conical cavity 3 to the interior of the reaction chamber 4, thereby improving the feeding efficiency inside the reaction chamber 4.

[0047] As an embodiment of the present invention, refer to Figure 1 An exhaust pipe is fixedly installed on the top of the tank body 1, and a pressure valve is fixedly installed inside the exhaust pipe.

[0048] Working principle: When producing glass raw fibers, firstly, the glass raw materials are put into the conical cavity 3 inside the feed box 2 through the feed port 32, and then the motor 5 is started, and then the motor 5 will drive the rotating shaft 6 inside the conical cavity 3 to rotate, and then the rotating shaft 6 drives the multiple crushing cutters 15 in the conical cavity 3 to rotate, and then the input glass raw materials are hit to break them into smaller particles for subsequent heating. However, for some larger, large-particle raw materials that are not broken in time, they will enter the interior of the conveying pipe 12 through the collecting port 14 at the bottom of the conveying pipe 12. At the same time, after the motor 5 is started, the rotating shaft 6 will drive the two rotating rods 7 to rotate through the two transmission belts 8, and then the two rotating rods 7 will be driven by the two first conical gears 9 respectively. The conveying rods 10 inside the two second bevel gears 11 are driven to rotate, and then the spiral conveying blades 13 inside the two conveying pipes 12 are driven to rotate respectively, so as to transport the larger particles of glass raw materials entering the collecting port 14, so that they are sent to the multiple crushing cutters 15 again, and then they can be crushed again to improve the crushing efficiency of the glass raw materials. The crushed glass raw materials can pass through the filter screen 16 to enter the inside of the guide port 17, and then enter the inside of the reaction chamber 4, and then heat it through the equipment inside the reaction chamber 4 to melt it. The melted glass raw materials can be drawn through the wire drawing equipment 33. After the rotating shaft 6 rotates, the reciprocating screw 18 inside the reaction chamber 4 can be driven to rotate. Since the screw sleeve 19 is fixed outside, Two of the multiple fixed rods 20 are respectively inserted into the limiting grooves 22. Therefore, after the reciprocating screw 18 rotates, the screw sleeve 19 will drive the multiple fixed rods 20 to move up and down inside the reaction chamber 4, and then the multiple fixed rods 20 will drive the scraper 21 to scrape the material on the inner wall of the reaction chamber 4. Since the scraper 21 is rotatably installed at one end of the fixed rod 20, and its rotation angle is 0° to 90°, when the scraper 21 moves up, due to the friction between the inner wall of the reaction chamber 4 and the scraper 21, the scraper 21 will be in a vertical state, and the molten raw material on the inner wall of the reaction chamber 4 will not be scraped off at this time. When the scraper 21 moves down, due to the friction between the reaction chamber 4 and the scraper 21, the scraper 21 is unfolded to be horizontal, and the molten raw material on the inner wall of the reaction chamber 4 is scraped off. The molten raw material is scraped off to improve the utilization rate of the glass raw material, and the difficulty of cleaning the inner wall of the reaction chamber 4 is also reduced. After the rotating shaft 6 rotates, it will drive the connecting rod 24 inside the circular cavity 23 to rotate, and then the connecting rod 24 will drive the first magnet 25 to rotate inside the circular cavity 23. Due to the mutual attraction between the first magnet 25 and the second magnet 28, when the first magnet 25 and the second magnet 28 are close to each other, the elastic airbag 27 will be pulled to expand through the second magnet 28, and then the external gas will be drawn into the interior of the strip cavity 26 through the air inlet pipe 30. After the first magnet 25 and the second magnet 28 are away from each other, the elastic airbag 27 will spray the gas through the nozzle 31 under the action of its own elastic force. Since the nozzle 31 is inclined and faces the filter 16,This facilitates blowing the fine materials in the conical cavity 3 into the reaction chamber 4, thereby improving the feeding efficiency into the reaction chamber 4.
