Description

Technical Field

[0001] The invention relates to the technical field of drying furnaces, and more specifically to a rotary drying furnace for producing potassium fluorotitanate. Background Art

[0002] Potassium fluorotitanate is a chemical compound that is mainly used in industry to manufacture titanic acid and metallic titanium. In addition, potassium fluorotitanate is also used as a catalyst for the synthesis of polypropylene, and as an additive in the manufacture of aluminum-titanium-boron alloys, aluminum processing, and light metal smelting. Therefore, it has important manufacturing value.

[0003] In the manufacturing process of potassium fluorotitanate, it is necessary to go through the drying process to remove moisture. At present, in the drying process of potassium fluorotitanate, a rotary drying furnace is often used to dry it. This drying furnace is mainly composed of a rotatable drying cylinder and a heating device installed on the surface of the drying cylinder. The drying cylinder has a certain inclination angle. When in use, the potassium fluorotitanate to be dried is fed from the high place of the drying cylinder, and then the heating device is started and the drying cylinder is rotated to allow the potassium fluorotitanate to flow to the lower place as the drying cylinder rotates. During the flow process, the moisture inside the potassium fluorotitanate will absorb the heat of the external heating device and automatically evaporate, thereby realizing the drying process.

[0004] Although the above-mentioned drying furnace is easy to use, it still has certain defects, namely:

[0005] During the drying process, the heating equipment directly heats the entire surface of the drying cylinder, and potassium fluorotitanate accumulates at the bottom of the drying cylinder under the action of gravity. As a result, the contact area of ​​potassium fluorotitanate is limited, which will require potassium fluorotitanate to stay in the drying cylinder for a long time to complete drying, resulting in low drying efficiency and very uneven drying of the material.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0033] Figure 1-Figure 10 The best embodiment of the present invention is shown below in conjunction with the attached Figure 1-Figure 10 The present invention is further described.

[0034] See attached Figure 1-Figure 10 A rotary drying furnace for potassium fluorotitanate production includes a drying cylinder 1, a base 2, a heating component and a driving component. The drying cylinder 1 is rotatably mounted on the base 2, and the feed end of the drying cylinder 1 is tilted higher than the discharge end. The heating component is fixedly mounted on the base 2, and the heating component is rotatably sleeved on the outside of the middle part of the drying cylinder 1, and a heating section is formed in the middle part of the drying cylinder 1. The driving component is mounted on the base 2, and the driving component is connected to the drying cylinder 1 and drives it to rotate. A rolling component is provided inside the drying cylinder 1, and the material can be rolled open by the rolling component. At the same time, the rolling component is arranged in the heating section of the drying cylinder 1, and a scraping component is built in the rolling component, and the material can be scraped by the scraping component and move synchronously with the rolling component. The rolling component is equipped with a vibration component, and the rolling component can be vibrated by the vibration component.

[0035] When in use, the potassium fluorotitanate to be dried is poured into the feed end of the drying cylinder 1, and the drying cylinder 1 is driven to rotate by the driving component. At this time, the potassium fluorotitanate will continuously move toward the discharge end as the drying cylinder 1 rotates and the drying cylinder 1 tilts. When the potassium fluorotitanate reaches the heating section of the drying cylinder 1, it will be heated to remove the internal moisture to complete the drying. Moreover, when the potassium fluorotitanate is in the heating section of the drying cylinder 1, it will be rolled thin and expanded by the rolling component to contact with more surfaces of the drying cylinder 1 for heating, thereby effectively improving the drying efficiency.

[0036] The rolling assembly includes a roller 3 and a power assembly. The roller 3 is rotatably installed in the drying cylinder 1. A rolling portion 4 and a feeding portion 5 are provided on the surface of the roller 3. The rolling portion 4 is a semi-cylinder coaxial with the drying cylinder 1. At the same time, there is a rolling space between the rolling portion 4 and the inner wall of the drying cylinder 1. The feeding portion 5 is a plane and closes the top of the rolling portion 4. There is a feeding space between the feeding portion 5 and the inner wall of the drying cylinder 1. At the same time, the feeding space is larger than the rolling space. In this way, potassium fluorotitanate that enters the feeding space first will enter the rolling space as the roller 3 rotates, and will be rolled open due to the small rolling space.

[0037] Furthermore, a plurality of levers may be provided on the outer wall of the rolling portion 4 so as to further disperse the materials in the rolling space.

[0038] The power assembly is connected to the drum 3, and the drum 3 is driven to rotate by the power assembly. The power assembly includes a first motor 6 and a transmission shaft 7. A bracket 8 is fixedly installed inside the drying cylinder 1, and the transmission shaft 7 is rotatably connected to the bracket 8 through a bearing. The drum 3 is sleeved on the outside of the transmission shaft 7. Both ends of the drum 3 are fixedly connected to the transmission shaft 7 and can rotate synchronously with the transmission shaft 7. The first motor 6 is fixedly arranged on the side of the feed end of the drying cylinder 1, and the output shaft of the first motor 6 is coaxially connected to the transmission shaft 7. In this way, only the first motor 6 needs to be started, the first motor 6 will drive the transmission shaft 7 to rotate, and the transmission shaft 7 will drive the drum 3 to rotate. The rolling portion 4 of the drum 3 will roll the potassium fluorotitanate entering the bottom of the drum 3 to make it thinner and spread out along the inner wall of the drying cylinder 1, so that the potassium fluorotitanate can absorb more heat from the drying cylinder 1 at the same time.

[0039] The scraping component includes a scraper 9. A through groove is provided on the surface of the drum 3, and the scraper 9 is slidably installed in the through groove. In this way, during the rotation of the drum 3, the scraper 9 will follow the rotation and extend out under the action of centrifugal force to tightly adhere to the inner wall of the drying cylinder 1. In this way, the scraper 9 can scrape the potassium fluorotitanate during the rotation process to contact more inner walls of the drying cylinder 1, thereby further improving the heating efficiency.

[0040] The scraper 9 is equipped with a reset component, and the scraper 9 can be retracted into the drum 3 under the action of the reset component. The reset component includes a slide bar 10, a sleeve 11, a limit plate 12 and a reset spring 13. One end of the slide bar 10 is fixedly connected to the scraper 9, and the other end is slidably inserted in the sleeve 11. The sleeve 11 is fixedly installed in the drum 3, the limit plate 12 is slidably installed in the sleeve 11, and the limit plate 12 is fixedly connected to the end of the slide bar 10, and the reset spring 13 is installed in the sleeve 11. The reset spring 13 is sleeved outside the slide bar 10. At the same time, the limit plate 12 can drive the slide bar 10 to retract into the sleeve 11 under the action of the reset spring 13. In this way, the scraper 9 is retracted into the internal state of the drum 3 when the drum 3 does not rotate, thereby freeing up space for potassium fluorotitanate to enter the space between the drum 3 and the drying drum 1. In addition, the first motor 6 can be used to control the rotation speed of the drum 3, thereby controlling the centrifugal force, thereby controlling the extension distance of the scraper 9 to meet a variety of different usage requirements. For example, when the scraper 9 is extended to a small length, it can only scrape away the potassium fluorotitanate away from the inner wall area of ​​the drying cylinder 1 to contact the rest of the inner wall of the drying cylinder 1, while the remaining potassium fluorotitanate continues to contact the bottom of the drying cylinder 1, so that the same amount of potassium fluorotitanate can be in contact with more inner walls of the drying cylinder 1.

[0041] The reset assembly may not be provided, and a push spring may be provided between the scraper 9 and the drum 3 , so that the push spring pushes the scraper 9 to move toward the conveying drum 3 , thereby pressing the outer side of the scraper 9 against the inner wall of the drying drum 1 .

[0042] The vibration assembly includes a compression spring 14, a baffle 15, a slide 16, a fixed wedge 17 and a movable wedge 18. The baffle 15 is fixedly mounted on the side of the bracket 8. The compression spring 14 is sleeved on the transmission shaft 7 and is between the baffle 15 and the roller 3. There are two groups of brackets 8, baffles 15 and compression springs 14, which are symmetrically distributed on both sides of the roller 3. The slide 16 is fixedly mounted inside the roller 3, and the roller 3 is slidably sleeved on the outside of the transmission shaft 7 through the slide 16. At the same time, the slide 16 can rotate synchronously with the transmission shaft 7. The fixed wedge 17 is fixedly mounted on the bracket 8, and the movable wedge 18 is fixedly mounted on the side of the roller 3. When the roller 3 rotates, the fixed wedge 17 and the movable wedge 18 cooperate to cause the roller 3 to reciprocate in the axial direction of the transmission shaft 7.

[0043] When the drum 3 rotates, the movable wedge 18 will be driven to rotate synchronously, and the wedge surface of the movable wedge 18 will contact the wedge surface of the fixed wedge 17. During the contact process, the movable wedge 18 will be pushed to slide, thereby driving the drum 3 to slide axially on the surface of the transmission shaft 7. During the sliding process of the drum 3, the compression spring 14 will be compressed. After the movable wedge 18 is separated from the fixed wedge 17, it will be reset under the action of the compression spring 14. This reciprocating movement can make the drum 3 vibrate continuously, which can shake off the potassium fluorotitanate attached to the surface of the drum 3 and achieve the effect of self-cleaning.

[0044] The heating assembly includes a heating seat 19, which is fixedly mounted on the base 2. A circular hole is provided in the middle of the heating seat 19, and the drying cylinder 1 can be rotatably inserted into the circular hole. An electric heating tube is provided in the heating seat 19, and the electric heating tube is distributed around the circular hole. In this way, the heating seat 19 can heat the drying cylinder 1 by simply energizing the electric heating tube.

[0045] The slide 16 and the transmission shaft 7 may be connected by a spline, so that the slide 16 and the transmission shaft 7 can have an axial relative movement, and the transmission shaft 7 can drive the slide 16 to rotate.

[0046] The driving assembly includes a second motor 20, a gear 21, a ring gear 22 and a load-bearing wheel 23. The second motor 20 is fixedly mounted on the base 2, the ring gear 22 is fixedly mounted on the surface of the drying cylinder 1, the gear 21 is fixedly mounted on the output shaft of the second motor 20, and the gear 21 is meshed with the ring gear 22. The load-bearing wheel 23 is rotatably mounted on the base 2. The load-bearing wheels 23 are arranged in several groups side by side, and each group of load-bearing wheels 23 includes two load-bearing wheels symmetrically arranged on both sides of the base 2. The drying cylinder 1 is located between the two load-bearing wheels 23 of each group, and each load-bearing wheel 23 cooperates to support the drying cylinder 1 so that the drying cylinder 1 can rotate freely.

[0047] Furthermore, an annular platform is provided at both ends of each load-bearing wheel 23, and a limiting platform is provided on the outer wall of the drying cylinder 1. The limiting platforms correspond to the number of groups of the load-bearing wheels 23 one by one, and each limiting platform is located between the annular platforms of the load-bearing wheels 23 on the corresponding side, so as to prevent the drying cylinder 1 from being separated. By simply starting the second motor 20, the second motor 20 will drive the gear 21 to rotate, and the gear 21 will drive the gear ring 22 to rotate, thereby driving the drying cylinder 1 to rotate.

[0048] It should be noted that there should be at least two groups of load-bearing wheels 23 arranged at intervals, so as to ensure the stability of the drying cylinder 1. In the present application, the two groups of load-bearing wheels 23 are distributed on both sides of the heating assembly.

[0049] A feed cylinder 24 is provided at the feed end of the drying cylinder 1. The feed cylinder 24 is a cylinder with one end closed. The open end of the feed cylinder 24 can be rotatably inserted into the end of the drying cylinder 1. A feed hopper 25 is installed on the upper side of the feed cylinder 24. A guide plate 26 is provided inside the feed cylinder 24. The guide plate 26 is in an inclined state, and the lower part of the guide plate 26 is close to the drying cylinder 1, which can facilitate the loading of materials when the drying cylinder 1 rotates.

[0050] The discharge end of the drying cylinder 1 is provided with a discharge cylinder 27, which is also a cylinder with one end closed. The discharge cylinder 27 is sleeved on the discharge end of the drying cylinder 1, and the drying cylinder 1 can rotate relative to the discharge cylinder 27. A discharge hopper 28 is installed at the bottom of the discharge cylinder 27, which can facilitate the unloading of materials when the drying cylinder 1 rotates.

[0051] Therefore, the complete usage process is to first start the second motor 20 to drive the gear 21 to rotate, and the gear 21 will drive the gear ring 22 to rotate, thereby driving the drying cylinder 1 to rotate, and then energize the electric heating tube inside the heating seat 19 to heat the drying cylinder 1 part in the middle of the heating seat 19. At this time, the potassium fluorotitanate to be dried can be poured into the feed hopper 25, and then the potassium fluorotitanate will enter the feed cylinder 24, and then flow into the drying cylinder 1 under the action of the guide plate 26. At this time, the potassium fluorotitanate will rotate with the rotation of the drying cylinder 1 and the drying cylinder 1 continuously moves toward the discharge end, and when the potassium fluorotitanate reaches the heating section of the drying cylinder 1, it will be heated to remove the internal moisture to complete the drying, and in this process, the first motor 6 can be started, the first motor 6 will drive the transmission shaft 7 to rotate, the transmission shaft 7 will drive the drum 3 to rotate, the rolling part 4 of the drum 3 will roll the potassium fluorotitanate entering the bottom of the drum 3, so that it becomes thinner and spreads along the inner wall of the drying cylinder 1, so that the potassium fluorotitanate can absorb more heat from the drying cylinder 1 at the same time, thereby improving the drying efficiency.

[0052] Among them, when the drum 3 rotates, when the feeding part 5 faces downward, since the feeding space is larger than the rolling space, the potassium fluorotitanate at the front end can quickly enter the bottom of the drum 3, and then continue to be rolled open as the rolling part 4 of the drum 3 turns around. The rolled potassium fluorotitanate will continue to move toward the discharge end of the drying drum 1 under the rotation and inclination angle of the drying drum 1.

[0053] In addition, the end of the drum 3 will also block the potassium fluorotitanate from entering the bottom of the drum 3 from the drying cylinder 1, ensuring that the amount of potassium fluorotitanate entering the bottom of the drum 3 remains constant, thereby ensuring the drying quality.

[0054] In summary, during the entire use process, the potassium fluorotitanate accumulated at the bottom of the drying cylinder 1 can be thinned and spread out by the rolling assembly so that it can be in contact with more surfaces of the drying cylinder 1 for heating, thereby effectively improving the drying efficiency.

[0055] At the same time, during use, when the rolling assembly is in operation, the scraping component will also drive the potassium fluorotitanate to rotate synchronously, so as to drive the potassium fluorotitanate to contact more inner walls of the drying cylinder 1, thereby further improving the drying efficiency.

[0056] In addition, during use, when the rolling assembly is running, it will further vibrate the rolling assembly through the vibration assembly, thereby shaking off the potassium fluorotitanate attached to the surface of the vibration assembly, achieving self-cleaning of the rolling assembly, and ensuring that the output potassium fluorotitanate is consistent with the input. In addition, the vibration process is also conducive to the escape of water vapor in the gaps of the potassium fluorotitanate, further promoting the drying efficiency.

[0057] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
