Description

Technical Field

[0001] The present invention relates to the technical field of chemical product production, in particular to drying equipment and a drying method for potassium fluoroborate production. Background Art

[0002] Potassium fluoborate, an important inorganic chemical raw material, is widely used in industries such as metallurgy, electronics, and glass. Drying is a key step in the production of potassium fluoborate, aiming to remove moisture from the product to ensure its purity and quality. Traditional drying equipment typically uses hot air circulation or direct heating to accelerate moisture evaporation by increasing the surface temperature of the material. However, these traditional methods have significant drawbacks when processing potassium fluoborate.

[0003] First, during the drying process, traditional drying equipment often distributes hot air unevenly, resulting in uneven heating of the material, overdrying some areas and underdrying others, affecting the overall quality of the product. Secondly, when processing potassium fluoroborate with a high water content, traditional drying equipment consumes a large amount of energy to maintain a high temperature environment, which not only increases production costs but also may cause certain environmental pollution. Furthermore, the high-temperature gas containing water vapor generated by traditional drying equipment during the drying process is usually discharged directly into the atmosphere, which not only wastes energy but also may cause thermal pollution to the environment.

[0004] In response to the above problems, this invention document proposes drying equipment and a drying method for potassium fluoroborate production. Summary of the Invention

[0018] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0019] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection", and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0020] Example 1: Reference Figure 1-11A drying device includes a drying oven 1, a sealing plate 8 fixedly mounted at the top opening of the drying oven 1, and an air inlet 41 formed on the inner wall of the bottom of one side of the drying oven 1. Multiple mounting racks 2 are welded at equal intervals within the drying oven 1, and electric heating tubes 3 are fixedly mounted at equal intervals within each mounting rack 2 for heating the gas within the drying oven 1.

[0021] like Figure 1 and Figure 4 As shown, a feeding mechanism is provided in the drying box 1, and the feeding mechanism includes a feeding box 9 that passes through the sealing plate 8 and is fixedly connected to the sealing plate 8. A rotating shaft 15 is rotatably connected in the drying box 1, and a sorting net barrel 16 is fixedly mounted on the rotating shaft 15. The purpose of providing the sorting net barrel 16 is to achieve preliminary dehydration of potassium fluoroborate for potassium fluoroborate raw materials with a water content greater than 20%. The bottom opening of the feeding box 9 is engaged with the sorting net barrel 16, and a discharge port is provided on the bottom inner wall of one side of the feeding box 9. A first feeding pipe 10 and a second feeding pipe 11 are respectively fixedly mounted on the top inner wall of the feeding box 9. The top ends of the first feeding pipe 10 and the second feeding pipe 11 are fixedly connected to the same shunt pipe 12, and a butt-joint pipe 13 is welded to one end of the shunt pipe 12. A driving motor 14 is fixedly mounted on one side of the drying box 1, and the output shaft of the driving motor 14 extends into the drying box 1 and is fixedly connected to one end of the rotating shaft 15. By connecting an external delivery pipe to the docking pipe 13, the moist potassium fluoroborate is dispersed and delivered from the diverter pipe 12 to the feed box 9. The potassium fluoroborate is pre-filtered using the sorting net barrel 16 to reduce its humidity. The drive motor 14 is then activated to rotate the shaft 15, causing the sorting net barrel 16 to roll, transporting the potassium fluoroborate and discharging it from the discharge port.

[0022] like Figure 4 As shown, a drain plate 17 is fixedly installed through the discharge port. One side of the drain plate 17 extends into the drying oven 1 and wraps around the sorting net barrel 16. The drain plate 17 is also provided with a guide protrusion 18, which cooperates with the subsequent conveying mechanism. When the sorting net barrel 16 rotates, the potassium fluoroborate can be conveyed to the conveying mechanism through the drain plate 17 and the guide protrusion 18. The water filtered by the sorting net barrel 16 can pass through the sorting net barrel 16 and fall onto the drain plate 17, and then be discharged through the drainage hole.

[0023] like Figure 7As shown, the conveying mechanism includes a driving roller 19 rotatably connected to the drying box 1. Synchronous pulleys 32 are fixedly mounted on both the driving roller 19 and the rotating shaft 15. The two synchronous pulleys 32 are driven by a common synchronous belt 33. A driven roller 20 is also connected to the drying box 1. A conveyor belt 21 is driven by both the driven roller 20 and the driving roller 19. The conveyor belt 21 contacts one side of the guide protrusion 18. Multiple flow holes 211 are evenly spaced in the conveyor belt 21, allowing hot air to pass through the conveyor belt 21 and dry the potassium fluoroborate at high temperatures. A discharge hole is formed on the top inner wall of the drying box 1 on the other side. A discharge plate 22 is fixedly mounted through the discharge hole. Driven by the two synchronous pulleys 32 and the synchronous belt 33, the driving roller 19 rotates the rotating shaft 15. This, supported by the driven roller 20, drives the conveyor belt 21. After being transported to the conveyor belt 21 by the guide protrusion 18 , the potassium fluoroborate can keep moving so as to receive hot air and then be dried. After being dried, the potassium fluoroborate can fall onto the discharge plate 22 and be discharged from the discharge plate 22 .

[0024] like Figure 8 As shown, a horizontally arranged rectangular frame 23 is fixedly mounted on each side of the top inner wall of the drying oven 1. Adjustment plates 25 are slidably connected within the rectangular frame 23, and the two ends of the driven roller 20 are rotatably connected to the two adjustment plates 25. An adjustment screw 24 is rotatably connected to the inner wall of one side of the rectangular frame 23. An adjustment nut 26 is fixedly mounted on one side of the adjustment plate 25. One end of the adjustment screw 24 passes through the adjustment nut 26 and the adjustment plate 25 and extends to the outside of the drying oven 1. The adjustment screw 24 is threadedly connected to the adjustment nut 26. By rotating the adjustment screw 24 and the adjustment nut 26, the adjustment plate 25 can be driven to move laterally, thereby adjusting the lateral position of the driven roller 20. Therefore, when the driving roller 19 and the driven roller 20 support and drive the conveyor belt 21, the conveyor belt 21 can be tightened to prevent slipping.

[0025] like Figure 10As shown, a pad 27 is fixedly installed in the drying box 1. The pad 27 passes through the conveyor belt 21 and is used to horizontally support the conveyor belt 21. A plurality of vent holes 28 are opened at equal intervals on the pad 27. Side baffles 29 are symmetrically fixedly installed on the top of the pad 27, respectively located on both sides of the conveyor belt 21. A plurality of dispersion plates 30 are arranged at equal intervals between the two side baffles 29. An ultrasonic vibrating plate is added to the bottom of the dispersion plate 30. Its power line is connected in parallel with the infrared lamp tube (31). When the infrared lamp tube 31 is started, 28kHz high-frequency vibration is generated synchronously. The two sides of the dispersion plate 30 are fixedly connected to the two side baffles 29 respectively. A plurality of evacuation ports 301 are opened at equal intervals on the bottom of the dispersion plate 30. A plurality of infrared lamp tubes 31 are also arranged between the two side baffles 29. The plurality of infrared lamp tubes 31 and the plurality of dispersion plates 30 are staggered. The infrared lamp tubes 31 are respectively fixedly connected to the two side baffles 29. When potassium fluoborate is transported by the conveyor belt 21, the pad 27 can be used to horizontally support the conveyor belt 21 so that the conveyor belt 21 will not be affected by the weight of the potassium fluoborate. In addition, the plurality of dispersion plates 30 can break up the potassium fluoborate during the conveying process so that the potassium fluoborate can be evenly dispersed and heated. At the same time, the infrared lamp 31 can emit light and heat after being powered on, so that the potassium fluoborate can be quickly dried in combination with the hot air.

[0026] like Figure 3 、 Figure 9 and Figure 10 As shown, the jet mechanism includes a mounting plate 4 fixedly mounted in the drying oven 1, two pulse air pumps 5 symmetrically fixedly mounted on the bottom of the mounting plate 4, the pulse frequency of the pulse air pump 5 being 0.5-2 Hz, and two dispersion boxes 6 symmetrically fixedly mounted on the top of the mounting plate 4, a plurality of exhaust holes 7 being evenly spaced on the top inner wall of the dispersion box 6. The output end of the pulse air pump 5 extends into the corresponding dispersion box 6 and is fixedly connected to the bottom inner wall of the dispersion box 6. After the plurality of electric heating tubes 3 are energized, the gas in the drying oven 1 can be heated, and then the high-temperature gas can be transported into the dispersion box 6 by starting the pulse air pump 5, and then the high-temperature gas can be transported upward through the plurality of exhaust holes 7, so that the high-temperature gas can pass through the conveyor belt 21 and the pad 27 to dry the potassium fluoroborate at high temperature.

[0027] This application can be used in the field of chemical product production technology, and can also be used in other fields applicable to this application.

[0028] Example 2: Reference Figure 1-2, based on the improvement of Example 1: A drying device for potassium fluoroborate production, which is applied to the field of chemical product production technology, the condensation and cooling mechanism includes two flow hoods 34 that penetrate and are fixedly connected to the sealing plate 8. A plurality of condensing tubes 35 are fixedly installed at equal intervals on the top inner wall of the flow hood 34. The condensing tubes 35 are lined with polytetrafluoroethylene, with a single length of ≥1.2m and an inclination angle of 15°. One end of the plurality of condensing tubes 35 is fixedly connected to the same annular tube 36, and a delivery pipe 37 is fixedly installed through one side inner wall of the annular tube 36. One end of the two delivery pipes 37 is fixedly connected to the same manifold box 38, which is fixedly installed on the top of the sealing plate 8. A flow pipe 39 is fixedly installed through one side inner wall of the manifold box 38, and an exhaust pipe 40 is fixedly installed through one side inner wall of the flow pipe 39. After potassium fluoroborate is baked by high-temperature gas and infrared lamp 31, the moisture attached to potassium fluoroborate can evaporate quickly to form water vapor. The water vapor can flow upward into the flow hood 34 along with the gas, and then disperse into multiple condenser tubes 35. The condenser tubes 35 have a long stroke, so the water vapor will liquefy into water during the flow process, and then enter the collection box 38 along with the gas, and finally be discharged through the flow tube 39. At the same time, the exhaust pipe 40 provided can facilitate the discharge of gas, and the top of the exhaust pipe (40) can also be connected to a heat exchanger, and its heat exchange outlet is connected to the air inlet (41) through a pipe to form a heat energy circulation system; the heat exchanger is electrically connected to the electric push rod 46, and when the exhaust temperature is detected to be greater than 60°C, the electric push rod 46 can automatically open the adjustment hole 43.

[0029] A fixed plate 42 is fixedly installed within the drying oven 1. This plate is located above the air inlet 41 and has an adjustment hole 43 formed therein. A connecting plate 45 is slidably connected therein. A flow restrictor 44 is fixedly installed on the top of the connecting plate 45, and the flow restrictor 44 fits tightly against the top of the fixed plate 42. An electric push rod 46 is bolted to the inner wall of the bottom of the other side of the drying oven 1. The output shaft of the electric push rod 46 is fixedly connected to the bottom of one side of the connecting plate 45. By activating the electric push rod 46, the connecting plate 45 is moved laterally, which in turn causes the flow restrictor 44 to move laterally, thereby adjusting the flow area of the adjustment hole 43. This facilitates the adjustment of the air intake into the drying oven 1 during high-temperature drying of potassium borofluoride.

[0030] The present invention provides a drying method, which is applied to the drying equipment for potassium fluoroborate production as described above, comprising the following steps: S1. First, the electric push rod 46 is activated to drive the connecting plate 45 to move laterally, thereby driving the flow limiting plate 44 to move laterally, thereby adjusting the flow area of the adjustment hole 43, so that when the potassium fluoroborate is dried at high temperature, the air intake into the drying box 1 can be conveniently adjusted; S2. Powering on the plurality of electric heating tubes 3, thereby heating the gas in the drying box 1, so that the gas in the drying box 1 is in a high temperature state; S3, by connecting the external conveying pipe with the butt joint 13, the moist potassium fluoroborate can be dispersed and conveyed into the feed box 9 through the diversion pipe 12. At this time, the potassium fluoroborate can be pre-filtered by the sorting net barrel 16 to reduce the humidity of the potassium fluoroborate. Then, the drive motor 14 is started to drive the rotating shaft 15 to rotate. At this time, the sorting net barrel 16 can be rolled to transport the potassium fluoroborate, so that the potassium fluoroborate can be transported to the conveyor belt 21 by the guide plate 17 and the guide protrusion 18; S4. The driving roller 19 can rotate the rotating shaft 15 under the transmission action of the two synchronous wheels 32 and the synchronous belt 33. At this time, with the support and cooperation of the driven roller 20, the conveyor belt 21 can be driven to move. After the potassium fluoroborate is transported to the conveyor belt 21 through the guide protrusion 18, it can keep moving. When the conveyor belt 21 is used to transport the potassium fluoroborate, the pad 27 can be used to horizontally support the conveyor belt 21 so that the conveyor belt 21 is not affected by the weight of the potassium fluoroborate. In addition, the multiple dispersion plates 30 can break up the potassium fluoroborate during the transportation of the potassium fluoroborate, so that the potassium fluoroborate can be evenly dispersed and heated. At the same time, the infrared lamp 31 can emit light and heat after being powered on, so that the potassium fluoroborate can be quickly dried in combination with the hot air. S5. At the same time, starting the two pulse air pumps 5 can deliver the high-temperature gas into the dispersion box 6, and then the high-temperature gas can be delivered upward through the multiple exhaust holes 7, so that the high-temperature gas can pass through the conveyor belt 21 and the pad 27 to dry the potassium fluoborate at high temperature, and the high-temperature gas output by the pulse air pump 5 can be in a pulse flow shape, so that when the potassium fluoborate is dried, the gas around the potassium fluoborate can be disturbed, so that the potassium fluoborate can be baked by the hot air and dried quickly; S6. After potassium fluoroborate is baked by high-temperature gas and infrared lamp 31, the moisture attached to potassium fluoroborate can evaporate quickly to form water vapor. The water vapor can flow upward into the flow hood 34 along with the gas, and then disperse into multiple condensers 35. The condenser 35 has a long stroke, so it will liquefy into water during the flow of water vapor, and then enter the collection box 38 along with the gas, and finally be discharged through the flow pipe 39. At the same time, the exhaust pipe 40 provided can facilitate the discharge of gas.
