Description

Technical Field

[0001] This invention belongs to the field of water-quenched slag fiberization production technology, and particularly relates to a continuous water-quenched slag fiberization production equipment. Background Technology

[0002] In industrial production processes, water-quenched slag is a common industrial solid waste with a considerable output. On the other hand, continuous fibers, with their superior properties such as high strength and high modulus, exhibit huge market demand in numerous fields such as aerospace, automotive, and construction engineering. Utilizing water-quenched slag to prepare continuous fibers is of great significance for comprehensive resource utilization, as it can transform waste into high-value materials and improve resource utilization efficiency.

[0003] Existing continuous fiber production equipment for water-quenched slag generally pre-treats the water-quenched slag, mixes it with an appropriate amount of additives, puts it into a furnace and heats it to a molten state, then uses spinning equipment to extrude the molten liquid at a certain speed, and then uses a specific cooling device to quickly cool and shape it into continuous fibers.

[0004] However, in the existing process, when the water-quenched slag is melted, as the melting temperature gradually increases, the strength of the continuous fiber shows a trend of first increasing and then decreasing. This is because at lower temperatures, the water-quenched slag cannot be fully melted, resulting in defects inside the fiber and lower strength. On the other hand, excessively high temperatures may cause some components to volatilize or undergo excessive reactions, which also affects the fiber performance. Furthermore, a large number of bubbles will appear when the water-quenched slag is melted. The bubbles mixed in the water-quenched slag melt will affect the continuous stability of the water-quenched slag melt in the fiber drawing process. Finally, the mismatch between the drawing speed and the cooling speed during the drawing process will cause fiber breakage, which will also affect the fiber performance of the water-quenched slag fiberization. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous fiberization production equipment for water-quenched slag, which aims to solve the technical problem that the fiber properties need to be improved during the fiberization of water-quenched slag in the prior art.

[0017] Further technical solution: The scraping mechanism includes a No. 3 motor, a rotating plate, a rotating shaft, and an elastic torsion spring;

[0018] The No. 3 motor is fixedly connected to the upper end face of the furnace. The output shaft of the No. 3 motor is fixedly connected to a rotating plate.

[0021] The bottom of the filter plate is provided with a groove, which is connected to the rotating sleeve, and the rotating sleeve stores cerium dioxide powder. A control valve is provided between the rotating sleeve and the groove.

[0022] Further technical solution: The thrust mechanism includes an electric telescopic seat, a connecting shaft, a gear shaft, transmission gears, and a rack plate;

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. Control system, which can control the melting uniformity, bubble density and cooling rate of water-quenched slag melt by controlling the guiding mechanism, conveying mechanism, scraping mechanism, filtering mechanism, thrust mechanism and cooling mechanism, thereby controlling the fiber quality after the water-quenched slag melt is formed.

[0031] 2. During the melting process, the conveying mechanism can vertically push the water-quenched slag molten material, improve the mixing uniformity of the water-quenched slag molten material in the furnace, and the particles in the water-quenched slag falling from a height are filtered and collected by the filtration mechanism. The unmelted water-quenched slag particles are accelerated to mix and melt with the water-quenched slag molten material in the furnace under the push of the filtration mechanism, thereby increasing the melting speed of the water-quenched slag particles.

[0032] 3. With the combined action of the conveying mechanism, scraping mechanism and filtration mechanism, not only can the melting speed of water-quenched slag particles, the mixing uniformity of water-quenched slag melt and the heating uniformity of water-quenched slag melt be improved, but the inner wall of the furnace and the outer wall of the conveying mechanism can also be rapidly heated through the scraping mechanism and filtration mechanism, thereby avoiding uneven temperature field distribution between the middle and the outside of the furnace and further improving the heating uniformity of water-quenched slag melt.

[0033] 4. The thrust mechanism can drive the filter mechanism to swing, preventing the filter mechanism from clogging. At the same time, the thrust mechanism can crush the water-quenched slag particles filtered out by the filter mechanism, further ensuring the flow efficiency of the filter mechanism while improving the crushing effect of the water-quenched slag particles.

[0034] 5. The conveying mechanism can filter the foam in the water-quenched slag molten material. The control system can adjust the filtration mechanism according to the density of the bubbles filtered by the conveying mechanism. The filtration mechanism releases cerium dioxide powder in a quantitative manner. The cerium dioxide decomposes and releases a certain amount of oxygen, which causes the bubbles to increase in volume and rise faster to be released, thereby achieving the purpose of defoaming.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0046] like Figures 1-8As shown, a continuous fiberization production equipment for water-quenched slag provided by the present invention includes a support frame 1, a furnace 2 fixedly connected to the support frame 1, a spinneret 3 connected to the outlet of the furnace 2, a material passage hole 13 provided on the support frame 1, a winding mechanism can be provided at the lower part of the material passage hole 13, a first electric rod 10 is provided on both sides of the material passage hole 13, a second electric rod 11 is horizontally provided at the telescopic end of the first electric rod 10, and a guide mechanism 4 for guiding the fiber is fixedly connected to the telescopic end of the second electric rod 11, and a cooling mechanism 9 for cooling the fiber is connected to the guide mechanism 4.

[0047] A conveying mechanism 5 is provided at the bottom center of the support frame 1. The conveying mechanism 5 can vertically push the water-quenched slag molten material and filter the foam in the water-quenched slag molten material. A scraping mechanism 6 is provided in the furnace 2. The scraping mechanism 6 can scrape the water-quenched slag molten material on the inner wall of the furnace 2 and the outer wall of the conveying mechanism 5. The scraping mechanism 6 is connected to a filtering mechanism 7. The filtering mechanism 7 can filter the water-quenched slag particles in the furnace 2. A thrust mechanism 8 is fixedly connected to the conveying mechanism 5. The thrust mechanism 8 can push the filtering mechanism 7 to swing. At the same time, the thrust mechanism 8 can crush the water-quenched slag particles filtered by the filtering mechanism 7.

[0048] The filter mechanism 7 stores cerium dioxide powder and is capable of quantitatively releasing cerium dioxide powder.

[0049] The control system can regulate the melting uniformity, bubble density, and fiber drawing cooling rate of the water-quenched slag melt by controlling the guiding mechanism 4, conveying mechanism 5, scraping mechanism 6, filtering mechanism 7, thrust mechanism 8, and cooling mechanism 9, thereby controlling the fiber quality after the water-quenched slag melt is formed.

[0050] In this embodiment, the water-quenched slag is pretreated and mixed with an appropriate amount of additives, then put into the furnace 2 and heated to a molten state. During the melting process, the conveying mechanism 5 can vertically push the water-quenched slag molten material, improving the mixing uniformity of the water-quenched slag molten material in the furnace 2. The particles in the water-quenched slag falling from a height are filtered and collected by the filtering mechanism 7. The unmelted water-quenched slag particles are accelerated to mix and melt with the water-quenched slag molten material in the furnace 2 under the push of the filtering mechanism 7, thereby increasing the melting speed of the water-quenched slag particles.

[0051] Start the scraping mechanism 6, which can scrape off the water-quenched slag on the inner wall of the furnace 2 and the outer wall of the conveying mechanism 5, so as to prevent the water-quenched slag from sticking to the side wall of the furnace 2 and the outer wall of the conveying mechanism 5.

[0052] With the combined action of conveying mechanism 5, scraping mechanism 6 and filtering mechanism 7, not only can the melting speed of water-quenched slag particles, the mixing uniformity of water-quenched slag melt and the heating uniformity of water-quenched slag melt be improved, but the inner wall of furnace 2 and the outer wall of conveying mechanism 5 can be rapidly heated through scraping mechanism 6 and filtering mechanism 7, thereby avoiding uneven temperature field distribution between the middle and the outside of furnace 2 and further improving the heating uniformity of water-quenched slag melt.

[0053] The thrust mechanism 8 can drive the filter mechanism 7 to swing, preventing the filter mechanism 7 from clogging. At the same time, the thrust mechanism 8 can crush the water-quenched slag particles filtered out by the filter mechanism 7, further ensuring the flow efficiency of the filter mechanism 7 while improving the crushing effect of the water-quenched slag particles.

[0054] In the above process, the conveying mechanism 5 can filter the foam in the water-quenched slag melt. The control system can adjust the filtering mechanism 7 according to the density of the bubbles filtered by the conveying mechanism 5. The filtering mechanism 7 quantitatively releases cerium dioxide powder (cerium dioxide decomposes at high temperature to release a certain amount of oxygen, which diffuses in the water-quenched slag melt, penetrates into the bubbles in the water-quenched slag melt, reduces the partial pressure of the gas in the bubbles, causes it to continue to absorb gas, and promotes the bubbles to increase in volume and rise faster to release, thereby achieving the purpose of defoaming and clarification).

[0055] Afterwards, the water-quenched slag molten material in furnace 2 enters the spinneret 3. The spinneret 3 extrudes the water-quenched slag molten material at a certain speed to form continuous fibers. After being guided by the guiding mechanism 4 and cooled by the cooling mechanism 9, the continuous fibers are collected by the winding mechanism.

[0056] like Figure 7 As shown, the guiding mechanism 4 includes a housing 41, a first motor 42, a rotating roller 43, a partition 44, a guide plate 45, a baffle 46, and a limiting plate 47.

[0057] The housing 41 is fixedly connected to the telescopic end of the second electric rod 11. One end of the housing 41 is fixedly connected to the first motor 42. The output shaft of the first motor 42 is fixedly connected to the rotating roller 43. The rotating roller 43 is provided with multiple partitions 44 at equal intervals along its length direction, and the sidewall of the rotating roller 43 is provided with multiple guide plates 45 inclined along the same rotation direction.

[0058] A baffle 46 is rotatably connected to the lower part of the opening of the housing 41 by a spring, and a limiting plate 47 is fitted into the end of the baffle 46.

[0059] In this embodiment, the two No. 2 electric rods 11 are activated to extend simultaneously. The two No. 2 electric rods 11 drive the housing 41 connected to them to move closer. At this time, the rotating rollers 43 in the two housings 41 move closer to each other. The fibers pulled out of the spinneret 3 are separated by the partitions 44 on the rotating rollers 43. At the same time, the partitions 44 on the two rotating rollers 43 guide the fibers.

[0060] To prevent the fibers from sticking to the partitions 44, the first motors 42 on the two housings 41 are started to rotate simultaneously. The two first motors 42 drive the rollers 43 connected to them to rotate. The two rollers 43 drive the partitions 44 connected to them to guide the fibers. At the same time, the partitions 44 rotate continuously, thereby preventing the partitions 44 from sticking to the fibers. Meanwhile, all the partitions 44 are in constant contact with the fibers, thereby removing the heat from the fibers. The partitions 44 can guide the fibers and cool them down at the same time.

[0061] When the two No. 1 electric rods 10 are activated to extend and retract simultaneously, the height position of the two guide mechanisms 4 can be adjusted, thereby adjusting the guiding position of the two guide mechanisms 4 on the fibers.

[0062] During the above process, the baffle 46 and the limiting plate 47 can elastically limit the fiber, thereby further preventing the fiber from sticking to the partition 44 and thus getting entangled in the shell 41.

[0063] like Figure 3 As shown, the conveying mechanism 5 includes a sleeve 51, a second motor 52, a pusher blade 53, and a filter plate 54.

[0064] The sleeve 51 is fixedly connected to the inner end face of the furnace 2. The bottom of the sleeve 51 has multiple openings. The bottom surface of the furnace 2 is fixedly connected to a second motor 52. The output shaft 63 of the second motor 52 is spirally provided with a pusher blade 53 and a filter plate 54 along its length. The filter plate 54 is located on the upper part of the pusher blade 53.

[0065] In this embodiment, the second motor 52 is started, which drives the pusher blade 53 to rotate. The pusher blade 53 conveys the water-quenched slag molten material upward in the sleeve 51, thereby realizing the vertical circulation mixing of the water-quenched slag molten material and improving the mixing uniformity and temperature uniformity of the water-quenched slag molten material. During this process, when the water-quenched slag particles are conveyed out of the sleeve 51 and fall, the filter mechanism 7 can collect the water-quenched slag particles.

[0066] When the water-quenched slag is conveyed to the sleeve 51, under the filtering action of the filter plate 54, the air bubbles in the water-quenched slag continue to adhere to the filter plate 54. As the water-quenched slag is conveyed, the air bubbles on the filter plate 54 are continuously broken and replenished. The control system can adjust the filter mechanism 7 according to the air bubble density on the filter plate 54, thereby removing the air bubbles in the water-quenched slag.

[0067] like Figure 4 As shown, the scraping mechanism 6 includes a No. 3 motor 61, a rotating plate 62, a rotating shaft 63, and an elastic torsion spring 64;

[0068] The No. 3 motor 61 is fixedly connected to the upper end face of the furnace 2. The output shaft of the No. 3 motor 61 is fixedly connected to a rotating plate 62. Both ends of the rotating plate 62 are rotatably connected to a rotating shaft 63. An elastic torsion spring 64 is provided between the rotating shaft 63 and the rotating plate 62. The lower end of the rotating shaft 63 is fixedly connected to a No. 1 scraper 65. The No. 1 scraper 65 is in contact with the inner wall of the furnace 2. The No. 1 scraper 65 is fixedly connected to a No. 2 scraper 66 through a connecting rod. The No. 2 scraper 66 is in contact with the outer wall of the sleeve 51. The connecting rod is in contact with the bottom surface of the furnace 2.

[0069] In this embodiment, motor 61 is started, which drives the rotating plate 62 to rotate. The rotating plate 62 drives two rotating shafts 63 to rotate. The two rotating shafts 63 drive the first scraper 65 connected to them to scrape off the water-quenched slag adhering to the inner wall of the furnace 2. At the same time, the connecting rod scrapes off the water-quenched slag adhering to the bottom surface of the furnace 2. The second scraper 66 scrapes off the water-quenched slag on the outer wall of the sleeve 51. Through the cooperation of the first scraper 65, the connecting rod and the second scraper 66, water-quenched slag can be prevented from adhering to the inner wall, inner end face and outer wall of the sleeve 51 of the furnace 2, improving the mixing uniformity of the water-quenched slag in the furnace 2. At the same time, the water-quenched slag adhering to the furnace 2 can be prevented from affecting the heat conduction in the furnace 2 and causing uneven heat distribution in the furnace 2.

[0070] like Figure 5 As shown, the filtration mechanism 7 includes a rotating sleeve 71, a filter plate 72, a flow guide groove 73, and a groove 74.

[0071] The rotating sleeve 71 is fixedly connected to the rotating shaft 63. The rotating sleeve 71 is fixedly connected to the filter plate 72. The filter plate 72 has a plurality of flow guide grooves 73 spaced apart, and a plurality of filter holes are provided on the flow guide grooves 73.

[0072] The bottom of the filter plate 72 is provided with a groove 74, which is connected to the rotating sleeve 71. The rotating sleeve 71 stores cerium dioxide powder, and a control valve is provided between the rotating sleeve 71 and the groove 74.

[0073] In this embodiment, since the rotating sleeve 71 is fixedly connected to the rotating shaft 63, and the rotating shaft 63 is connected to the rotating plate 62 by an elastic torsion spring 64, the rotating sleeve 71 drives the filter plate 72 to swing. When the rotating sleeve 71 drives the filter plate 72 to move in a circular motion around the center of the furnace 2, each guide hole groove 73 on the filter plate 72 will filter and collect the water-quenched slag particles in the furnace 2. The unmelted water-quenched slag particles are accelerated to mix and melt with the water-quenched slag melt in the furnace 2 under the push of the filter mechanism 7, thereby increasing the melting speed of the water-quenched slag particles. At the same time, the water-quenched slag melt will improve the mixing effect when it passes through the guide hole groove 73.

[0074] When the filter plate 72 comes into contact with the thrust mechanism 8, under the pushing action of the thrust mechanism 8 and the elastic limiting action of the elastic torsion spring 64, the filter plate 72 will swing back and forth as it passes the thrust mechanism 8. Under the reverse impact of the water-soluble slag molten material, the filter holes on the guide hole groove 73 are cleared, thereby preventing water-quenched slag particles from clogging the filter holes on the filter plate 72.

[0075] The control system opens the control valve, and after the rotating sleeve 71 quantitatively introduces cerium dioxide into the slot 74, the control valve closes. At this time, the cerium dioxide in the slot 74 reacts at high temperature and releases oxygen. Since there are many water-quenched slag particles accumulated in the guide slot 73 in the furnace 2, many bubbles are generated after the water-quenched slag particles are crushed and dissolved. The oxygen released by the cerium dioxide can increase the volume of the bubbles and accelerate their rise and release. Therefore, the slot 74 is set at the lower part of the guide slot 73. By releasing cerium dioxide into the slot 74, the defoaming rate of the water-quenched slag melt can be improved.

[0076] like Figure 3 and Figure 5 As shown, the thrust mechanism 8 includes an electric telescopic seat 81, a connecting shaft 82, a gear shaft 83, a transmission gear 84, and a rack plate 85;

[0077] The fixed end of the electric telescopic seat 81 is fixedly connected to the sleeve 51. The telescopic end of the electric telescopic seat 81 is rotatably connected to the connecting shaft 82. The connecting shaft 82 is fixedly connected to the gear shaft 83 and the transmission gear 84. The upper side of the filter plate 72 is fixedly connected to the rack plate 85. The transmission gear 84 can mesh with the rack plate 85.

[0078] In this embodiment, when the electric telescopic seat 81 retracts, the gear shaft 83 can push the filter plate 72 to swing, thereby preventing the guide hole groove 73 on the filter plate 72 from becoming blocked. When the electric telescopic seat 81 extends, under the push of the gear shaft 83, not only can the swing amplitude of the filter plate 72 be increased, improving the unblocking capacity of the guide hole groove 73 on the filter plate 72, but also when the filter plate 72 and the gear shaft 83 move relative to each other, the rack plate 85 on the filter plate 72 meshes with the transmission gear 84. At this time, with the cooperation of the rack plate 85 and the transmission gear 84, while the gear shaft 83 moves relative to the filter plate 72, the gear shaft 83 rotates itself. The gear shaft 83 crushes and pulverizes the water-quenched slag particles in the guide hole groove 73, thereby increasing the dissolution rate of the water-quenched slag particles.

[0079] After the water-quenched slag particles in the guide hole groove 73 are crushed and dissolved, they can improve the heat conduction between the scraping mechanism 6 and the filtering mechanism 7, thereby reducing the temperature difference between the inner wall of the furnace 2 and the outer wall of the conveying mechanism 5, and improving the overall thermal uniformity in the furnace 2.

[0080] like Figure 6 As shown, the cooling mechanism 9 includes a water tank 91, a first water pump 92, a fan 93, and a second water pump 94;

[0081] The upper end face of the water tank 91 is connected to the housing 41. A first water pump 92 is fixedly connected to one end of the housing 41. The first water pump 92 is connected to the rotating roller 43 through a rotating joint. Several spray holes are opened on the end face of the guide plate 45 close to the rotating roller 43. A fan 93 is fixedly connected to the back of the housing 41. The fan 93 can blow air into the housing 41. A second water pump 94 is connected between the housing 41 and the water tank 91. A row of water spray holes is provided on the lower side of the inner end face of the housing 41. A pressure sensor is provided between the side of the baffle 46 and the limiting plate 47. The pressure sensor is electrically connected to the control system.

[0082] In this embodiment, when the two housings 41 are close together and the partitions 44 on the two rollers 43 limit the fiber, the spray holes on the partitions 44 spray the fiber to cool it down. At the same time, under the sealing effect of the two housings 41 and the two baffles 46, the spray can be concentrated in the area near the fiber without spreading in large quantities, thereby improving the cooling effect of the spray on the fiber.

[0083] Furthermore, when the spray holes on each partition 44 spray, they can also spray and wet the side surface of one side of the partition 44, thereby guiding the fibers with the partition 44 and improving the contact cooling effect of the partition 44 on the fibers. Moreover, the probability of thermal adhesion between the surface of the partition 44 and the high-temperature fibers after atomization cooling is greatly reduced.

[0084] The fan 93 can blow air into the housing 41. Under the guidance of the baffle 46, the air flows upward between the two rotating rollers 43, thereby cooling the fiber along the fiber length direction.

[0085] When the fibers become thermally adhered to the surface of the partition 44 and are drawn into the housing 41, the fibers squeeze the limiting plate 47. The pressure sensor transmits a signal to the control system, which increases the airflow of the fan 93. As the roller 43 drives all the partitions 44 to rotate, the airflow direction in the housing 41 changes continuously due to the obstruction of the partitions 44, thus blowing the adhered fibers at multiple angles. On the other hand, driven by the airflow, the baffle 46 swings back and forth, which can push the fibers to separate from the partitions 44. At this time, the control system starts the second water pump 94 to supply water to the housing 41. The water spray holes on the housing 41 wash and separate the fibers adhering to the partitions 44. Under the guidance of the baffle 46, most of the cooling water flows back into the housing 41 for recycling.

[0086] The present invention provides a continuous fiberization production equipment for water-quenched slag, wherein the control system includes: a monitoring module, which includes a first infrared temperature monitor, a second infrared temperature monitor, and a high-temperature resistant monitor 12.

[0087] The furnace 2 has multiple No. 1 infrared temperature monitors inside, the support frame 1 is equipped with a No. 2 infrared temperature monitor located on the material passage hole 13, and the rotating plate 62 is equipped with a high temperature resistant monitor 12 located on the sleeve 51.

[0088] The processing module can calculate the maximum temperature difference value of each infrared temperature monitor, the temperature value of the second infrared temperature monitor, and the bubble density on the upper part of the sleeve 51 recorded by the high temperature monitor 12 through the data processor. It can also compare the maximum temperature difference value, temperature value, and bubble density with the temperature difference threshold, temperature threshold, and bubble density threshold in the data processor to form judgment information.

[0089] The control module can control the guiding mechanism 4, conveying mechanism 5, scraping mechanism 6, filtering mechanism 7, thrust mechanism 8 and cooling mechanism 9 based on the judgment information of the processing module.

[0090] In this embodiment, when the maximum temperature difference value of each infrared temperature monitor exceeds the preset temperature difference threshold, the control system controls the conveying mechanism 5, scraping mechanism 6, filtering mechanism 7 and thrust mechanism 8 to adjust the heating uniformity of the water-quenched slag in the furnace 2.

[0091] When the bubble density recorded by the high-temperature monitor 12 on the upper part of the sleeve 51 exceeds the bubble density threshold, the control system controls the conveying mechanism 5 and the filtering mechanism 7 to defoam the water-soluble slag melt.

[0092] When the temperature value of the second infrared temperature monitor exceeds the temperature threshold, the control system adjusts the cooling rate of the fiber by controlling the guide mechanism 4 and the cooling mechanism 9.

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.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
