Description

Technical Field

[0001] This invention relates to the field of drying technology, and in particular to a strontium fluoride dryer and its preparation method. Background Technology

[0002] Strontium fluoride dryers are mainly used for drying strontium fluoride and related materials, and are commonly used in the chemical, metallurgical, and ceramic industries. Strontium fluoride is an important chemical raw material widely used in the manufacture of optoelectronic materials, glass, ceramics, and other products. Due to its properties, strontium fluoride requires high-efficiency and precise drying equipment to ensure product quality.

[0003] Because strontium fluoride has strong hygroscopic properties, when its surface is wet, moisture easily forms a bridging effect between the particles, causing the particles to stick together and form clumps. Some existing drying equipment interferes with the material mechanically, such as by stirring or rotating, but if the strontium fluoride clumps are too tightly packed, the equipment cannot effectively disperse the clumps, thus affecting the uniformity of drying. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a strontium fluoride dryer and its preparation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A strontium fluoride dryer and its preparation method are disclosed, comprising a drying cylinder and a base plate. The drying cylinder is internally fitted with heating wires for heating and drying the strontium fluoride particles inside. A left end cover and a right end cover are fixedly installed on the top of the base plate, and the drying cylinder is rotatably mounted between the left and right end covers. The dryer also includes:

[0007] A plurality of material-pulling plates are uniformly fixedly installed on the inner wall of the drying cylinder in the circumferential direction, and are used to move the strontium fluoride particles by means of the plurality of material-pulling plates when the drying cylinder rotates.

[0008] A sieve plate, installed inside the drying cylinder, is used to sieve strontium fluoride particles;

[0009] A crushing mechanism, installed at the bottom of the screening plate, is used to crush agglomerated strontium fluoride particles.

[0010] As a further embodiment of the present invention, the crushing mechanism includes a receiving hopper, and a plurality of rectangular openings are provided through the upper surface of the screening plate. The receiving hopper is installed at the position corresponding to the rectangular openings. Crushing rollers are rotatably installed between the inner walls of opposite ends of the receiving hopper, and crushing teeth adapted to the crushing rollers are installed on the inner wall of the receiving hopper.

[0011] As a further embodiment of the present invention, a support guide rail is fixedly installed between the left end cover and the right end cover, the screening plate is slidably installed on the top of the support guide rail, and a connecting component is installed between the receiving hopper and the support guide rail.

[0012] As a further embodiment of the present invention, the connecting assembly includes a first spring rod fixedly installed at the bottom of the support guide rail, and the telescopic end of the first spring rod is fixedly installed on the outer surface of the receiving hopper.

[0013] As a further embodiment of the present invention, a rotating assembly is installed between the crushing roller and the screening plate. The rotating assembly includes a transmission gear fixedly installed at the center of rotation of the crushing roller. Multiple second spring rods are fixedly installed on the lower surface of the screening plate. A transmission rack is fixedly installed at the telescopic end of the multiple second spring rods. The transmission rack meshes with the transmission gear. A strip-shaped opening for the movement of the second spring rods is provided through the upper surface of the support guide rail.

[0014] As a further embodiment of the present invention, an eccentric wheel is also fixedly installed at the rotation center of the crushing roller.

[0015] As a further embodiment of the present invention, a C-shaped lever is fixedly installed at one end of the screening plate near the right end cover. The C-shaped lever is slidably installed on the outer surface of the right end cover. A guide ring is fixedly installed on the outer periphery of the drying cylinder. A wavy guide groove is formed on the outer periphery of the guide ring. The end of the C-shaped lever away from the screening plate is slidably installed on the inner wall of the wavy guide groove.

[0016] As a further embodiment of the present invention, a feed hopper is fixedly installed through the outer surface of the left end cover, and a discharge port is opened through the outer surface of the bottom of the right end cover, and a discharge hopper is fixedly installed on the outer surface of the right end cover near the discharge port.

[0017] As a further embodiment of the present invention, a support frame is fixedly installed at the top of the base plate, a drive wheel is rotatably installed inside the support frame, a friction ring is fixedly installed on the outer periphery of the drying cylinder, the drive wheel abuts against the outer periphery of the friction ring, a drive motor is fixedly installed on the outer surface of the support frame, and the output end of the drive motor passes through the outer surface of the support frame and is fixedly installed with the rotation center of the drive wheel.

[0018] A method for drying strontium fluoride includes the following steps:

[0019] S1: The strontium fluoride particles to be dried are fed into the drying cylinder from the feed hopper. The drive motor drives the drive wheel to rotate, and the friction between the drive wheel and the friction ring drives the drying cylinder to rotate. Several material-pulling plates installed on the inner wall of the drying cylinder move the strontium fluoride particles, so that the strontium fluoride particles can be continuously turned over inside the drying cylinder, so that the strontium fluoride particles are heated evenly.

[0020] S2: When the strontium fluoride particles are pushed upward by the material-pushing plate in the drying cylinder, the strontium fluoride particles pushed to the top position will fall onto the screening plate under their own gravity, so that the screening plate can screen and disperse the strontium fluoride particles.

[0021] S3: As the drying cylinder rotates, it will drive the guide ring to rotate. Since the end of the C-shaped lever is slidably installed with the inner wall of the wavy guide groove on the outer circumference of the guide ring, the guide ring can drive the screening plate to move back and forth along the length of the support guide rail through the wavy guide groove and the C-shaped lever when rotating, so that the screening plate can screen the strontium fluoride particles. The qualified strontium fluoride particles fall into the bottom of the drying cylinder after passing through the screening plate, while the agglomerated strontium fluoride particles will fall into the receiving hopper from the rectangular opening.

[0022] S4: When the screening plate moves, the transmission rack will move synchronously through the second spring rod, so that the transmission rack can drive the crushing roller to rotate through the transmission gear meshing with it, so that the crushing roller can cooperate with the crushing teeth installed on the inner wall of the receiving hopper to crush the agglomerated strontium fluoride particles.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. When the screening plate moves, the transmission rack will move synchronously through the second spring rod, so that the transmission rack can drive the crushing roller to rotate through the transmission gear meshing with it. This allows the crushing roller to work with the crushing teeth installed on the inner wall of the receiving hopper to crush the agglomerated strontium fluoride particles and ensure the uniformity of drying of the strontium fluoride particles.

[0025] 2. As the crushing roller rotates, it will drive the eccentric wheel to rotate. Since the entire receiving hopper is installed at the bottom of the support guide rail through the first spring rod, the eccentric wheel can drive the receiving hopper to shake up and down when it rotates, so as to shake the strontium fluoride particles inside the receiving hopper and prevent the strontium fluoride particles from getting stuck, which would affect the crushing effect of the crushing roller.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] See attached document Figure 1 - Appendix Figure 8 A strontium fluoride dryer includes a drying cylinder 1 and a base plate 24. The drying cylinder 1 is internally fitted with heating wires for heating and drying the strontium fluoride particles inside. The base plate 24 has an inclined platform structure, allowing the strontium fluoride particles to slowly move to the right end cover 3 under the rotation of the drying cylinder 1, so that the dried strontium fluoride particles can be discharged from the discharge hopper 5. A left end cover 2 and a right end cover 3 are fixedly installed on the top of the base plate 24, and the drying cylinder 1 is rotatably installed between the left end cover 2 and the right end cover 3. The dryer also includes:

[0038] Several material-pulling plates 6 are evenly fixedly installed on the inner wall of the drying cylinder 1 in the circumferential direction, and are used to paddle the strontium fluoride particles through the material-pulling plates 6 when the drying cylinder 1 rotates.

[0039] Screening plate 8 is installed inside the drying cylinder 1 and is used to screen strontium fluoride particles;

[0040] The crushing mechanism is installed at the bottom of the screening plate 8 and is used to crush the agglomerated strontium fluoride particles.

[0041] A feed hopper 4 is fixedly installed through the outer surface of the left end cover 2. A discharge port is opened through the outer surface of the bottom of the right end cover 3, and a discharge hopper 5 is fixedly installed on the outer surface of the right end cover 3 near the discharge port. A support frame 21 is fixedly installed at the top of the bottom plate 24. A drive wheel 22 is rotatably installed inside the support frame 21. A friction ring 20 is fixedly installed on the outer periphery of the drying cylinder 1. The drive wheel 22 abuts against the outer periphery of the friction ring 20. A drive motor 23 is fixedly installed on the outer surface of the support frame 21. The output end of the drive motor 23 passes through the outer surface of the support frame 21 and is fixedly installed at the rotation center of the drive wheel 22.

[0042] In use, the strontium fluoride particles to be dried are fed into the drying cylinder 1 from the feed hopper 4. The drive motor 23 drives the drive wheel 22 to rotate, and the friction between the drive wheel 22 and the friction ring 20 drives the drying cylinder 1 to rotate. Several material-pulling plates 6 installed on the inner wall of the drying cylinder 1 agitate the strontium fluoride particles, so that the strontium fluoride particles can be continuously turned over inside the drying cylinder 1, so that the strontium fluoride particles are heated evenly and the drying effect is improved.

[0043] In this embodiment, a C-shaped lever 17 is fixedly installed at one end of the sieve plate 8 near the right end cover 3. The C-shaped lever 17 is slidably installed on the outer surface of the right end cover 3. A guide ring 18 is fixedly installed on the outer periphery of the drying cylinder 1. A wavy guide groove 19 is opened on the outer periphery of the guide ring 18. The end of the C-shaped lever 17 away from the sieve plate 8 is slidably installed on the inner wall of the wavy guide groove 19.

[0044] As the drying cylinder 1 rotates, it will drive the guide ring 18 to rotate. Since the end of the C-shaped lever 17 is slidably installed with the inner wall of the wave-shaped guide groove 19 opened on the outer periphery of the guide ring 18, the guide ring 18 can drive the screening plate 8 to move back and forth along the length direction of the support guide rail 7 through the wave-shaped guide groove 19 and the C-shaped lever 17 when rotating, so that the screening plate 8 can perform screening operation on strontium fluoride particles and improve the screening effect.

[0045] In this embodiment, the crushing mechanism includes a receiving hopper 11. Multiple rectangular openings 9 are provided through the upper surface of the screening plate 8. The receiving hopper 11 is installed at the corresponding rectangular openings 9. A crushing roller 12 is rotatably mounted between the inner walls of opposite ends of the receiving hopper 11. Crushing teeth adapted to the crushing roller 12 are installed on the inner wall of the receiving hopper 11. A rotating assembly is installed between the crushing roller 12 and the screening plate 8. The rotating assembly includes a transmission gear 15 fixedly mounted at the rotation center of the crushing roller 12. Multiple second spring rods 13 are fixedly mounted on the lower surface of the screening plate 8. A transmission rack 14 is fixedly mounted at the telescopic end of the multiple second spring rods 13. By applying a downward thrust to the transmission rack 14 through the second spring rods 13, it can be ensured that the transmission rack 14 is always meshed with the transmission gear 15. The transmission rack 14 meshes with the transmission gear 15. A strip-shaped opening for the movement of the second spring rods 13 is provided through the upper surface of the supporting guide rail 7.

[0046] When the screening plate 8 moves, it will drive the transmission rack 14 to move synchronously through the second spring rod 13, so that the transmission rack 14 can drive the crushing roller 12 to rotate through the transmission gear 15 that meshes with it. This allows the crushing roller 12 to work with the crushing teeth installed on the inner wall of the receiving hopper 11 to crush the agglomerated strontium fluoride particles and ensure the uniformity of drying of the strontium fluoride particles.

[0047] In this embodiment, a support guide rail 7 is fixedly installed between the left end cover 2 and the right end cover 3. The screening plate 8 is slidably installed on the top of the support guide rail 7. A connecting component is installed between the receiving hopper 11 and the support guide rail 7. The connecting component includes a first spring rod 10 fixedly installed at the bottom of the support guide rail 7. The telescopic end of the first spring rod 10 is fixedly installed on the outer surface of the receiving hopper 11. An eccentric wheel 16 is also fixedly installed at the rotation center of the crushing roller 12.

[0048] While the crushing roller 12 rotates, it will drive the eccentric wheel 16 to rotate. Since the receiving hopper 11 is installed at the bottom of the support guide rail 7 through the first spring rod 10, the eccentric wheel 16 can drive the receiving hopper 11 to shake up and down when it rotates, so as to shake the strontium fluoride particles inside the receiving hopper 11 and avoid the strontium fluoride particles from getting stuck, which would affect the crushing effect of the crushing roller 12.

[0049] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: In use, the strontium fluoride particles to be dried are fed into the drying cylinder 1 from the feed hopper 4. The drive motor 23 drives the drive wheel 22 to rotate, and the friction between the drive wheel 22 and the friction ring 20 drives the drying cylinder 1 to rotate. The several material-pushing plates 6 installed on the inner wall of the drying cylinder 1 push the strontium fluoride particles, so that the strontium fluoride particles can be continuously turned inside the drying cylinder 1, so that the strontium fluoride particles are heated evenly and the drying effect is improved.

[0050] When the strontium fluoride particles are pushed upward by the material-pushing plate 6 in the drying cylinder 1, the strontium fluoride particles pushed to the top position will fall onto the screening plate 8 under their own gravity, so that the screening plate 8 can screen and break up the strontium fluoride particles, and facilitate the screening plate 8 to intercept and crush the agglomerated strontium fluoride particles.

[0051] As the drying cylinder 1 rotates, it will drive the guide ring 18 to rotate. Since the end of the C-shaped lever 17 is slidably installed with the inner wall of the wave-shaped guide groove 19 opened on the outer periphery of the guide ring 18, the guide ring 18 can drive the screening plate 8 to move back and forth along the length direction of the support guide rail 7 through the wave-shaped guide groove 19 and the C-shaped lever 17 when rotating, so that the screening plate 8 can perform screening operation on strontium fluoride particles and improve the screening effect.

[0052] Strontium fluoride particles that pass the screening process fall into the bottom of the drying cylinder 1 after passing through the screening plate 8, while agglomerated strontium fluoride particles fall into the receiving hopper 11 through the rectangular opening 9 for subsequent crushing.

[0053] When the screening plate 8 moves, the transmission rack 14 will move synchronously through the second spring rod 13, so that the transmission rack 14 can drive the crushing roller 12 to rotate through the transmission gear 15 meshing with it, so that the crushing roller 12 can work with the crushing teeth installed on the inner wall of the receiving hopper 11 to crush the agglomerated strontium fluoride particles and ensure the uniformity of drying of the strontium fluoride particles.

[0054] While the crushing roller 12 rotates, it will drive the eccentric wheel 16 to rotate. Since the receiving hopper 11 is installed at the bottom of the support guide rail 7 through the first spring rod 10, the eccentric wheel 16 can drive the receiving hopper 11 to shake up and down when it rotates, so as to shake the strontium fluoride particles inside the receiving hopper 11 and avoid the strontium fluoride particles from getting stuck, which would affect the crushing effect of the crushing roller 12.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.
