Description

Technical Field

[0001] This invention relates to the field of basalt fiber preparation technology, and specifically discloses a melting and drawing device for preparing basalt fibers. Background Technology

[0002] Basalt fiber is a continuous fiber made from basalt rock material, which is melted at 1450℃~1500℃ and then drawn at high speed through a platinum-rhodium alloy drawing spindle. It not only has high strength, but also has a variety of excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. It is a new type of inorganic, environmentally friendly, green, and high-performance fiber material.

[0003] Temperature control is crucial in the basalt fiber drawing process. If the temperature of the melt in the platinum-rhodium alloy drawing spindle is too low, crystallization will easily occur, affecting the quality of the basalt fibers obtained from the drawing process. On the other hand, if the temperature is too high during the drawing process, the basalt melt will break due to insufficient cooling, making continuous production impossible.

[0004] For example, utility model patent application number 201620688427X discloses a basalt fiber drawing spindle, including a spindle body, a base plate, and a temperature control component. The spindle body has a groove-shaped cavity, and the base plate is installed inside the groove-shaped cavity of the spindle body. A cavity for basalt melt is formed between the groove-shaped cavity and the base plate. The temperature control component is used to control the temperature of the basalt melt. The temperature control component includes a heating element and a temperature sensor, which are electrically connected. Although the basalt fiber drawing spindle disclosed in this patent achieves temperature control of the melt in the cavity, it cannot effectively control the cooling and forming temperature during the fiber drawing process, resulting in fiber breakage during the drawing process and preventing continuous fiber drawing production. In addition, existing basalt fiber drawing equipment suffers from two problems: firstly, the middle part of the spindle body is prone to downward deformation due to the gravity of the melt during long-term drawing; secondly, the shaped basalt fibers cannot be synchronously and evenly wound onto multiple winding drums during the winding process, resulting in uneven winding of the basalt fibers. Based on the aforementioned shortcomings of existing basalt fiber drawing equipment, this application proposes a melting and drawing equipment for preparing basalt fibers that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a melting and drawing device for preparing basalt fibers, so as to solve the technical problems and shortcomings of existing basalt drawing devices mentioned in the background art.

[0006] This invention is achieved through the following technical solution:

The melt chamber is fixedly installed at the upper end of the frame. The drawing die is sealed in the mounting port at the bottom of the melt chamber. Electrodes are connected to both the left and right ends of the drawing die. A cylindrical nozzle connected to each hole is provided on the lower surface of the drawing die. A nozzle temperature control component is provided below the melt chamber.

[0008] The leak nozzle temperature control assembly includes a heat exchange medium flow box, in which multiple horizontal partitions are arranged vertically. The left and right ends of the multiple horizontal partitions are staggered and connected vertically. A heat exchange sleeve corresponding to each cylindrical leak nozzle is provided on the heat exchange medium flow box, and the heat exchange sleeve extends vertically through the heat exchange medium flow box and the multiple horizontal partitions. Both ends of the heat exchange medium flow box have outwardly extending end edges, each end edge having a through hole. An adjusting screw connected to the lower surface of the molten liquid chamber passes through the through hole. An adjusting nut is screwed onto the adjusting screw at the lower end of the end edge. A feed pipe and a discharge pipe are connected to the side end of the heat exchange medium flow box. The ends of the feed pipe and discharge pipe are connected to a heat exchange medium storage tank, and a circulating pump connected to the feed pipe is provided on the heat exchange medium storage tank.

[0009] As a further provision of the above scheme, the feed pipe is connected to the upper side of the heat exchange medium storage tank, and there are two discharge pipes. The two discharge pipes are connected to the upper and lower sides of the heat exchange medium storage tank below the feed pipe. The ends of the two discharge pipes converge and connect to the heat exchange medium storage tank. A receiving groove is provided on the side of the heat exchange medium storage tank between the two discharge pipes. A sealing and bonding block is provided in the receiving groove. A telescopic drive is provided on the outer side of the receiving groove to push the sealing and bonding block into the heat exchange medium storage tank to seal the connection between the two discharge pipes.

[0010] As a further feature of the above scheme, the heat exchange medium flow box is provided with no less than three horizontal baffles, and no less than one communication port is opened on the horizontal baffle near the feed pipe and the discharge pipe.

[0011] As a further feature of the above scheme, the heat exchange sleeve is made of copper, and the inner diameter of the heat exchange sleeve is the same as the outer diameter of the cylindrical nozzle.

[0012] As a further feature of the above scheme, two symmetrically arranged side plates are welded to the upper surface of the wire drawing plate, and a hanging plate is connected to the top of the side plates. A support plate that interacts with the hanging plate is welded to the inner wall of the molten liquid chamber, and a ceramic gasket is provided between the hanging plate and the support plate.

[0013] As a further feature of the above scheme, a cover plate is detachably installed on the upper surface of the molten chamber, a feeding pipe is provided on the rear side of the molten chamber, and a filter cylinder is detachably installed in the molten chamber located directly below the inner end of the feeding pipe.

[0014] As a further feature of the above solution, a rectangular opening is provided at the upper end of the frame located directly below the wire drawing stencil, and the wire winding and drawing device is located in the frame below the rectangular opening.

[0015] As a further provision of the above solution, the winding and drawing device includes a drive shaft with a rotatable frame, a row of winding drums on the drive shaft, and a power component for realizing the rotation of the drive shaft on an outer side of the frame.

[0016] As a further feature of the above solution, a slide rail parallel to the drive shaft is fixedly installed in the frame above the drive shaft. A moving bar is slidably installed on the slide rail. Guide plates corresponding to the upper and lower parts of each take-up drum are connected at intervals on the moving bar. A transmission assembly for realizing the reciprocating movement of the moving bar is provided on the top of the frame.

[0017] As a further provision of the above solution, the transmission assembly includes two bearing seats fixed to the top wall of the frame, a reciprocating lead screw is rotatably connected between the two bearing seats, and a lead screw motor is connected to the outer end of the reciprocating lead screw. A lead screw nut that matches the reciprocating lead screw is fixedly connected to the moving bar.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1) In the process of preparing basalt fibers, the melting and drawing equipment disclosed in this invention involves the molten material discharged from the drawing die flowing downwards along the cylindrical nozzle. The cylindrical nozzle then comes into contact with the heat exchange sleeve in the nozzle temperature control assembly, and the heat exchange medium is introduced into the heat medium flow box to cool the heat exchange sleeve. This achieves a local cooling effect on the cylindrical nozzle. By ensuring that the temperature of the molten liquid above the drawing die is within the optimal range, the rapid cooling and shaping of the basalt fibers during the drawing process is guaranteed, effectively avoiding fiber breakage during the drawing process and ensuring continuous and stable operation of the entire drawing process.

[0020] 2) When cooling the cylindrical nozzle, the leak temperature control component disclosed in this invention can also change the flow path of the heat exchange medium inside the heat exchange medium flow box by controlling the telescopic drive component, thereby adjusting the effective contact area between the heat exchange sleeve and the heat exchange medium, and thus achieving effective control of the temperature of the heat exchange sleeve. This control method can quickly switch and adjust the drawing speed of basalt fiber, meeting the cooling and forming requirements of various drawing speeds in the basalt fiber drawing process, and has a wide range of applicability.

[0021] 3) The present invention further optimizes the design of the winding and drawing device. Through the design of the guide plate, a batch of basalt fibers drawn off can be wound onto the same winding drum through the guide holes. Then, during the winding and drawing process of the winding drum, the reciprocating screw and screw nut work together to make the moving bar move back and forth, which will drive all the guide plates to move back and forth. The basalt fibers passing through the guide plates will be evenly wound onto the winding drum, thereby ensuring the winding quality of the basalt fibers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-10 This application will be described in detail with reference to the embodiments.

[0042] Example 1

[0043] Example 1 discloses a melting and drawing apparatus for preparing basalt fibers, see attached diagram. Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4The main body of the equipment includes a frame 100, a molten metal chamber 200, a wire drawing screen 300, and a winding and drawing device 500. The molten metal chamber 200 is fixedly mounted on the upper end of the frame 100 by two end columns, and then the wire drawing screen 300 is sealed and installed in the mounting opening at the bottom of the molten metal chamber 200. To prevent the wire drawing screen 300 from deforming after long-term use, two symmetrically arranged side plates 303 are welded to the upper surface of the wire drawing screen 300. A hanging plate 304 is connected to the top of the side plates 303, and a support plate 201 that interacts with the hanging plate 304 is welded to the inner wall of the molten metal chamber 200. A ceramic gasket is placed between the hanging plate 304 and the support plate 201. In addition, a cover plate 202 is detachably installed on the upper surface of the molten basalt chamber 200, and a feeding pipe 203 is provided on the rear side of the molten basalt chamber 200. A filter cylinder 204 is detachably installed in the molten basalt chamber 200 located directly below the inner end of the feeding pipe 203. When molten basalt is added to the molten basalt chamber 200, it will first pass through the filter cylinder 204 for filtration, and then fall onto the wire drawing plate 300. After the equipment is shut down, the cover plate 202 can be opened to clean the impurities on the filter cylinder 204.

[0044] Reference Appendix Figure 1 and attached Figure 5 Electrodes 302 are connected to both ends of the wire drawing plate 300. A cylindrical nozzle 301 connected to each hole is provided on the lower surface of the wire drawing plate 300. A nozzle temperature control assembly 400 is located below the melt chamber 200. See the attached document for details of the nozzle temperature control assembly 400. Figure 6 Appendix Figure 7 and attached Figure 8 The device includes a heat exchange medium flow box 401, within which multiple horizontal baffles 402 are arranged vertically. The left and right ends of each horizontal baffle 402 are staggered, with vertically connected openings 403. A heat exchange sleeve 404, corresponding to each cylindrical nozzle 301, is provided on the heat exchange medium flow box 401, penetrating both the heat exchange medium flow box 401 and the multiple horizontal baffles 402. The heat exchange sleeve 404 is made of copper, and its inner diameter is the same as the outer diameter of the cylindrical nozzle 301, allowing the outer wall of the cylindrical nozzle 301 to fully contact the inner wall of the heat exchange sleeve 404 for heat exchange and cooling.

[0045] Both ends of the heat exchange medium flow box 401 have outwardly extending end edges 405, with through holes on the end edges 405. An adjusting screw 406, connected to the lower surface of the molten liquid chamber 200, passes through these through holes. An adjusting nut 407 is screwed onto the adjusting screw 406 at the lower end of the end edge 405. A feed pipe 408 and a discharge pipe 409 are connected to the side ends of the heat exchange medium flow box 401. The ends of the feed pipe 408 and the discharge pipe 409 are connected to a heat exchange medium storage tank 410, which is equipped with a circulating pump 411 connected to the feed pipe 408. The adjusting screw 406, adjusting nut 407, and end edges 405 allow adjustment of the position of the entire heat exchange medium flow box 401 relative to the cylindrical nozzle 301, enabling different positions of the cylindrical nozzle 301 to fit against the inner wall of the heat exchange sleeve 404, thereby achieving the effect of adjusting the cooling and forming of basalt wire.

[0046] Reference Appendix Figure 1 and attached Figure 9 A rectangular opening 101 is provided at the upper end of the frame 100 located directly below the drawing stencil 300. The winding and drawing device 500 is then installed in the frame 100 below the rectangular opening 101. The winding and drawing device 500 includes a drive shaft 501 rotatably mounted on the frame 100, a row of winding drums 502 mounted on the drive shaft 501, and a power assembly 503 for rotating the drive shaft 501 is provided on an outer side of the frame 100. The power assembly 503 includes a motor, a drive wheel, a driven wheel, and a transmission belt. The drive wheel and the driven wheel are connected to the motor and the outer end of the drive shaft 501, respectively. The transmission belt is then placed between the drive wheel and the driven wheel to achieve the rotation and drawing of the drive shaft 501.

[0047] Example 2

[0048] Example 2 discloses a melting and drawing device for preparing basalt fibers, which is an improved design based on Example 1. The similarities between it and Example 1 will not be described again.

[0049] Reference Appendix Figure 6 Appendix Figure 7 and attached Figure 8 In the design of the leak nozzle temperature control assembly 400 in this embodiment 2, the feed pipe 408 is first connected to the upper side of the heat exchange medium storage tank 410. In this embodiment 2, two discharge pipes 409 are provided, and the two discharge pipes 409 are connected to the upper and lower sides of the heat exchange medium storage tank 410 below the feed pipe 408. Then, the ends of the two discharge pipes 409 are converged and connected to the heat exchange medium storage tank 410.

[0050] A receiving groove 412 is provided on the side of the heat exchange medium storage tank 410 located between the two discharge pipes 409. A sealing and bonding block 413 is provided in the receiving groove 412. A telescopic drive component 414 is provided on the outer side of the receiving groove 412. Specifically, the telescopic drive component 414 can be an air pipe or an electric push rod. The telescopic drive component is extended into the receiving groove and connected to the sealing and bonding block 413. Under the action of the telescopic drive component 414, the sealing and bonding block 413 is pushed into the heat exchange medium storage tank 410, and the connection port 403 between the two discharge pipes 409 is sealed, thereby achieving the effect of adjusting the flow path of the heat exchange medium in the heat exchange medium flow box 401.

[0051] In the specific design process, the heat exchange medium flow box 401 in this embodiment 2 is provided with no less than three horizontal baffles 402, and no less than one communication port 403 is opened on the horizontal baffle 402 near the feed pipe 408 and the discharge pipe 409.

[0052] When the entire melting and drawing equipment is producing basalt fibers at high speed, the cylindrical nozzle 301 needs to be efficiently cooled. At this time, the sealing and bonding block 413 will retract into the receiving groove 412, allowing the heat exchange medium (such as heat transfer oil or warm water) to flow along all the meandering flow channels inside the heat exchange medium flow box 401, so that the heat exchange sleeve 404 is in contact with it from top to bottom, thereby achieving high-speed cooling and shaping during the drawing process. When producing basalt fibers at low speed, the connecting port 403 is blocked by the sealing and bonding block 413. At this time, the flow path of the heat exchange medium inside the heat exchange medium flow box 401 is halved, and the heat exchange area between it and the heat exchange sleeve 404 is reduced, thereby reducing the cooling rate during the low-speed drawing process, preventing the temperature of the molten liquid above the drawing nozzle from being too low and causing crystallization, and ensuring the drawing quality.

[0053] Example 3

[0054] Example 3 discloses a melting and drawing device for preparing basalt fibers, which is an improved design based on Example 1 or Example 2. The similarities between the device and Example 1 or Example 2 will not be described again.

[0055] In this embodiment 3, a slide rail 504 parallel to the drive shaft 501 is fixedly installed in the frame 100 located above the drive shaft 501. A moving bar 505 is slidably installed on the slide rail 504. A guide plate 506 corresponding to the upper and lower parts of each take-up drum 502 is connected at intervals on the moving bar 505. A transmission component for realizing the reciprocating movement of the moving bar 505 is provided on the top of the frame 100.

[0056] The specific transmission components include two bearing seats 507 fixed to the top wall of the frame 100, a reciprocating lead screw 508 rotatably connected between the two bearing seats 507, and a lead screw motor 509 connected to the outer end of the reciprocating lead screw 508. A lead screw nut 510 matching the reciprocating lead screw 508 is fixedly connected to the moving bar 505.

[0057] In this embodiment 3, the design of the guide plate 506 allows a batch of basalt fibers to be wound onto the same take-up drum 502 through the guide holes. During the winding process of the take-up drum 502, the reciprocating screw 508 and the screw nut 510 work together to make the moving bar 505 move back and forth along the slide rail 504. During its back and forth movement, it will drive all the guide plates 506 to move back and forth. The basalt fibers passing through the guide plates 506 will be evenly wound onto the take-up drum 502, thereby ensuring the winding quality of the basalt fibers.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
