Description

Technical Field

[0001] This utility model relates to the field of ferrite particle production technology, and more specifically, it relates to a fixture on a spray dryer for preparing nano ferrite particles. Background Technology

[0002] Nano-ferrite particles have broad application prospects in biomedicine (such as magnetothermal therapy and drug delivery), photocatalysis, and magnetic materials. The preparation of nano-ferrite particles generally adopts the chemical coprecipitation method, which is to prepare nano-ferrite particles by generating precipitates through chemical reactions in solution. In the current technology, a spray dryer is used to quickly dry the precursor solution obtained by the chemical coprecipitation method into powder, so that the precursor solution is dried in a short time. The particles obtained by spray drying are usually spherical, with good dispersibility and flowability, which is conducive to subsequent calcination and application.

[0003] However, the connection and fixation of the drying tower and cyclone separator, the drying tower and waste bottle, and the cyclone separator and collection bottle in a spray dryer are usually secured with clamps. This requires one hand to hold the cyclone separator, waste bottle, and collection bottle while the other hand locks the clamp. There is a risk of the fixed parts slipping out of one's hand, making operation inconvenient and reducing the ease of disassembly and assembly of the cyclone separator, waste bottle, and collection bottle. Furthermore, material residue can easily remain at the clamp connection points, which may affect the subsequent drying effect and product quality. It is necessary to clean the connection points of the drying tower and cyclone separator, the drying tower and waste bottle, and the cyclone separator and collection bottle in a timely manner, greatly increasing the number of times the cyclone separator, waste bottle, and collection bottle need to be disassembled and assembled. Therefore, it is necessary to design a fixing component for the spray dryer used in the preparation of nano-ferrite particles to facilitate the connection and fixation of the drying tower and cyclone separator, the drying tower and waste bottle, and the cyclone separator and collection bottle, improve the ease of disassembly and assembly of the cyclone separator, waste bottle, and collection bottle, avoid the risk of the fixed parts slipping out of one's hand, and ensure high safety.

[0007] Further configured, the first fixing part, the second fixing part, and the third fixing part each include two mounting plates, two fixing plates, a positioning buckle, and a positioning head. The two mounting plates of the first fixing part, the second fixing part, and the third fixing part are respectively movably connected to the first lifting platform, the second lifting platform, and the third lifting platform. The two fixing plates are respectively connected to the two mounting plates. The positioning buckle is hinged to one fixing plate, and the positioning head is connected to the other fixing plate and cooperates with the positioning buckle. The fixing plate has an arc-shaped slot, and the arc-shaped slots on the two fixing plates cooperate. An elastic pad is fixed in the arc-shaped slot.

[0008] Further configured, the positioning head includes a limiting rod, a stop rod, and a movable rod. The limiting rod and the movable rod are L-shaped hinged together, and a spring connected to the movable rod is connected to the limiting rod. One end of the stop rod is connected to the movable rod. A limiting hole is opened on the limiting rod to be movably connected to the limiting rod. The other end of the limiting rod is connected to a limiting block that engages with the limiting hole.

[0009] Further configured, the first lifting platform, the second lifting platform and the third lifting platform each include a shelf, a threaded tube and a threaded rod, the shelf is movably connected to the corresponding mounting plate, the shelf is rotatably connected to the corresponding threaded tube through a bearing, one end of the threaded rod is threadedly connected to the corresponding threaded tube, and the other end of the threaded rod is connected to the base.

[0010] A further configuration is provided, wherein the placement plate has a guide groove, and the mounting plate is connected to a slider that is slidably connected to the guide groove, and the slider is engaged with the guide groove.

[0011] Further configured, the first lifting platform, the second lifting platform, and the third lifting platform all have through holes, and the first lifting platform has two through holes.

Detailed Implementation

[0018] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0019] A fixing component for a spray dryer used in the preparation of nano-ferrite particles includes a base 1, which is installed at the bottom of the spray dryer body. A first lifting platform 2, a second lifting platform 3, and a third lifting platform 4 are connected to the base 1. A first fixing part 5 for fixing a drying tower 100 and a cyclone separator 200 is connected to the first lifting platform 2. A second fixing part 6 for fixing a drying tower 100 and a waste bottle 300 is connected to the second lifting platform 3. A third fixing part 7 for fixing a cyclone separator 200 and a collection bottle 400 is connected to the third lifting platform 4.

[0020] Place the collection bottle 400 on the shelf 20 of the third lifting platform 4. Hold the cyclone separator 200 with one hand and connect the upper part of the cyclone separator 200 to the air outlet pipe at the top of the spray dryer beforehand. Adjust the height of the third lifting platform 4 with the other hand so that the bottle mouth of the collection bottle 400 is in contact with the connection port at the bottom of the cyclone separator 200. At this time, the cyclone separator 200 and the collection bottle 400 are initially stabilized under the action of the third lifting platform 4 and do not need to be held by hand. The third fixing part 7 on the third lifting platform 4 fixes the connection between the cyclone separator 200 and the collection bottle 400, thereby realizing the connection and fixation of the cyclone separator 200 and the collection bottle 400. The operation is convenient and does not require one hand to hold the collection bottle 400 for fixing operations, reducing the risk of the collection bottle 400 falling out of hand when disassembling and assembling the collection bottle 400. The collection bottle 400 and the cyclone separator 200 are fixed under the action of the third lifting platform 4, which facilitates the subsequent fixation of the drying tower 100 and the cyclone separator 200.

[0021] Align the connection points of the drying tower 100 and the cyclone separator 200. Adjust the height of the third lifting platform 4 to align the height of the side connection port of the cyclone separator 200 with the side connection port of the drying tower 100. Adjust the height of the first lifting platform 2 so that the first fixing part 5 aligns with the connection points of the drying tower 100 and the cyclone separator 200. Fix the connection points of the drying tower 100 and the cyclone separator 200 with the first fixing part 5 on the first lifting platform 2. This achieves the connection and fixation of the drying tower 100 and the cyclone separator 200. The operation is convenient and does not require one hand to hold the cyclone separator 200 for fixing operations, reducing the risk of the cyclone separator 200 slipping out of your hand during disassembly and assembly, and ensuring high safety.

[0022] The waste bottle 300 is placed on the shelf 20 of the second lifting platform 3. The height of the second lifting platform 3 is adjusted so that the mouth of the waste bottle 300 abuts against the connection port of the drying tower 100. The second fixing part 6 on the second lifting platform 3 then secures the connection between the drying tower 100 and the waste bottle 300, thus achieving a convenient and safe connection. It eliminates the need to hold the waste bottle 300 with one hand during the fixing operation, reducing the risk of the waste bottle 300 slipping out of the hand during assembly and disassembly. Ultimately, the fixing components facilitate the connection and fixation of the drying tower 100 with the cyclone separator 200, the waste bottle 300, and the collection bottle 400, improving the ease of assembly and disassembly of the cyclone separator 200, waste bottle 300, and collection bottle 400, and preventing the fixed components from slipping out of the hand.

[0023] The first fixing part 5, the second fixing part 6, and the third fixing part 7 each include two mounting plates 8, two fixing plates 9, a positioning buckle 10, and a positioning head 11. The two mounting plates 8 of the first fixing part 5, the second fixing part 6, and the third fixing part 7 are movably connected to the first lifting platform 2, the second lifting platform 3, and the third lifting platform 4, respectively. The two fixing plates 9 are fixedly connected to the two mounting plates 8, respectively. The positioning buckle 10 is hinged to one fixing plate 9, and the positioning head 11 is fixedly connected to the other fixing plate 9 and cooperates with the positioning buckle 10. The positioning buckle 10 is ring-shaped and fits around the positioning head 11. The fixing plates 9 have arc-shaped slots 12, and the arc-shaped slots 12 on the two fixing plates 9 cooperate. An elastic pad 13 is fixed inside the arc-shaped slot 12.

[0024] After the height of the first lifting platform 2 is adjusted, the two mounting plates 8 of the first fixing part 5 move closer to each other on the first lifting platform 2, thereby bringing the two fixing plates 9 closer to each other. This causes the connection between the drying tower 100 and the cyclone separator 200 to be placed in the two arc-shaped slots 12 of the two fixing plates 9 and to abut against the elastic pads 13 in the arc-shaped slots 12. The positioning buckle 10 on one fixing plate 9 is then fitted onto the positioning head 11 on the other fixing plate 9 to fix the two fixing plates 9. This fixes the connection between the drying tower 100 and the cyclone separator 200 in the arc-shaped slots 12 of the two fixing plates 9, thus achieving the purpose of the first fixing part 5 in fixing the connection between the drying tower 100 and the cyclone separator 200.

[0025] Similarly, after the height of the second lifting platform 3 is adjusted, the two fixing plates 9 of the second fixing part 6 move closer to each other so that the connection between the drying tower 100 and the waste bottle 300 is placed in the two arc-shaped slots 12 of the two fixing plates 9 and abuts against the elastic pads 13 in the arc-shaped slots 12. With the positioning buckle 10 sleeved on the positioning head 11, the two fixing plates 9 are fixed, thereby fixing the connection between the drying tower 100 and the waste bottle 300 in the arc-shaped slots 12 of the two fixing plates 9, thus achieving the purpose of the second fixing part 6 to fix the connection between the drying tower 100 and the waste bottle 300.

[0026] Similarly, after the height of the third lifting platform 4 is adjusted, the two fixing plates 9 of the third fixing part 7 move closer to each other so that the connection between the cyclone separator 200 and the collection bottle 400 is placed in the two arc-shaped slots 12 of the two fixing plates 9 and abuts against the elastic pads 13 in the arc-shaped slots 12. With the positioning buckle 10 put on the positioning head 11, the two fixing plates 9 are fixed, thereby fixing the connection between the cyclone separator 200 and the collection bottle 400 in the arc-shaped slots 12 of the two fixing plates 9, thus achieving the purpose of the third fixing part 7 to fix the connection between the drying tower 100 and the waste bottle 300.

[0027] The positioning head 11 includes a limiting rod 14, a stop rod 15, and a movable rod 16. The limiting rod 14 and the movable rod 16 are L-shaped hinged together, and a spring 17 fixed on the limiting rod 14 and fixed to the movable rod 16 is fixed thereon. One end of the stop rod 15 is movably connected to the movable rod 16. The limiting rod 14 has a limiting hole 18 that is movably connected to the limiting rod 14. The other end of the limiting rod 14 is fixedly connected to a limiting block 19 that engages with the limiting hole 18.

[0028] When the positioning buckle 10 is fitted onto the positioning head 11, the two corresponding fixing plates 9 move closer together, further compressing the elastic pad 13 in the arc-shaped groove 12. This causes one end of the positioning buckle 10 to approach and fit onto the limiting rod 14. At this time, one end of the positioning buckle 10 abuts against the movable rod 16, compressing it and causing the movable rod 16 to rotate around the limiting rod 14 towards it. This compresses the spring 17, causing the stop rod 15 to move within the limiting hole 18, thus allowing the movable rod 16 to rotate smoothly towards the limiting rod 14. Positioning buckle 10 smoothly passes through movable rod 16 and is fitted onto limiting rod 14. Movable rod 16 returns to its original shape under the action of compression spring 17, forming an L-shape with limiting rod 14. During the process of moving rod 16 returning to its original shape, stop rod 15 moves within limiting hole 18 until limiting block 19 engages with limiting hole 18. At this time, movable rod 16, limiting rod 14 and stop rod 15 form a triangle, which engages with limiting block 19 and limiting hole 18, preventing positioning buckle 10 from detaching from limiting rod 14, thereby avoiding disconnection between positioning buckle 10 and positioning head 11, which would affect the connection and fixation of the two fixing plates 9.

[0029] When disassembling the cyclone separator 200, waste bottle 300, and collection bottle 400, press the movable rod 16 towards the limiting rod 14 so that the positioning buckle 10 passes through the movable rod 16 and disengages from the limiting rod 14, thereby facilitating the release of the corresponding fixing parts and realizing the disassembly of the corresponding cyclone separator 200, waste bottle 300, and collection bottle 400. The operation is convenient.

[0030] The first lifting platform 2, the second lifting platform 3, and the third lifting platform 4 each include a shelf 20, a threaded tube 21, and a threaded rod 22. The shelf 20 is movably connected to the corresponding mounting plate 8, and the shelf 20 is rotatably connected to the corresponding threaded tube 21 through a bearing. One end of the threaded rod 22 is threadedly connected to the corresponding threaded tube 21, and the other end of the threaded rod 22 is fixedly connected to the base 1.

[0031] By rotating the threaded tube 21, the threaded tube 21 moves up and down along the height direction of the threaded rod 22, thereby moving the corresponding shelf 20 up and down, and realizing the height adjustment of the corresponding first lifting platform 2, second lifting platform 3 and third lifting platform 4.

[0032] The shelf 20 has a guide groove 23, and the mounting plate 8 is connected to a slider 24 that is slidably connected to the guide groove 23, so that the mounting plate 8 can move on the shelf 20. This allows the two mounting plates 8 to move so that the two fixing plates 9 can move closer together to fix the corresponding connection points. The slider 24 is engaged with the guide groove 23. The cross-section of the slider 24 and the cross-section of the guide groove 23 are both T-shaped to prevent the mounting plate 8 from detaching from the shelf 20 when it moves on the shelf 20, thus affecting the movement of the mounting plate 8.

[0033] Through holes are provided on the shelf 20 of the first lifting platform 2, the shelf 20 of the second lifting platform 3, and the shelf 20 of the third lifting platform 4. The first lifting platform 2 has two through holes. The shelf 20 of the first lifting platform 2 is provided with a first guide rod 25 and a second guide rod 26 that are movably connected to the two through holes on the first lifting platform 2, respectively. The first guide rod 25 is movably connected to the through hole on the second lifting platform 3, and the second guide rod 26 is movably connected to the through hole on the third lifting platform 4.

[0034] The first guide rod 25 and the second guide rod 26 are designed to prevent the corresponding placement plate 20 from rotating when the threaded tube 21 is rotated, thus preventing the collection bottle 400 or waste bottle 300 on it from becoming unstable. Preventing the placement plate 20 from rotating also prevents the fixing part on it from rotating and not corresponding to the connection of the corresponding cyclone separator 200, waste bottle 300, and collection bottle 400, thus avoiding the need to readjust the angle of the corresponding fixing part and affecting the ease of installation.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
