Description

Technical Field

[0001] This utility model relates to the field of collector preparation technology, and in particular to a vacuum dehydration machine for collector semi-finished products. Background Technology

[0002] In fluorite beneficiation, collectors are key agents for separating fluorite minerals from gangue, and their performance directly affects beneficiation efficiency and the quality of fluorite concentrate. The production of collectors involves multiple processes, including mixing, reaction, and purification. The semi-finished product stage often contains excessive moisture, requiring dehydration treatment to reduce the moisture content and ensure the stability of subsequent processing and the effectiveness of the final product.

[0003] In existing technologies, when vacuum dehydrating semi-finished collectors, the raw material is introduced into the tank and sealed. Then, a vacuum device is activated to extract the air from the tank. The tank rotates and heats the raw material, causing the moisture inside the material to diffuse to the surface through pressure or concentration differences. Water molecules gain sufficient kinetic energy on the material surface and, after overcoming intermolecular attraction, diffuse into the low-pressure space of the vacuum chamber, where they are drawn away by a vacuum pump, thus separating from the solid and completing the drying process. However, because the semi-finished collector is in a moist state, adsorption occurs between the semi-finished collectors, which affects the efficiency of vacuum dehydration. Therefore, it is necessary to design a vacuum dehydrator for semi-finished collectors to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a vacuum dehydration machine for semi-finished collectors, comprising:

[0032] The frame 1 is equipped with a vacuum dehydration mechanism. It should be noted that the mechanism can fully stir and mix the semi-finished collector, avoid adsorption between the semi-finished collectors, and ensure the efficiency of vacuum dehydration of the semi-finished collector.

[0033] The vacuum dehydration mechanism includes a sleeve plate 2, a tank body 3, a reciprocating lead screw sleeve 4, a servo motor 5, a reciprocating lead screw 6, a connecting platform 1 7, a connecting platform 2 8, a mixing blade 1 9, and a guide rod 10;

[0034] The sleeve 2 is fixedly connected to the tank body 3 and the reciprocating screw sleeve 4. It should be noted that a heating bushing is provided in the interlayer of the tank body 3 for heating the inside of the tank body 3. This is existing technology and will not be described in detail here.

[0035] Servo motor 5 is fixedly installed on the top of frame 1. The output end of servo motor 5 is fixedly connected to reciprocating lead screw 6. Reciprocating lead screw 6 is threadedly connected to reciprocating lead screw sleeve 4. It should be noted that reciprocating lead screw 6 drives reciprocating lead screw sleeve 4 to move vertically back and forth through reciprocating helical grooves opened on the outer wall.

[0036] The bottom of the reciprocating screw 6 is fixedly connected to the connecting platform 7. The connecting platform 8 is rotatably mounted on the tank 3. The mixing blade 9 is fixedly mounted on the connecting platform 8. The guide rod 10 is fixedly mounted on the top of the connecting platform 8. The connecting platform 7 is slidably sleeved on the outside of the guide rod 10.

[0037] With the above structure, after the tank body 3 is evacuated, the servo motor 5 is started, which causes the reciprocating screw 6 to rotate. This causes the reciprocating screw sleeve 4 to move vertically back and forth, which in turn causes the sleeve plate 2 to drive the tank body 3 to move vertically back and forth, shaking the collector semi-finished material. The tank body 3 drives the connecting platform 8 to move vertically back and forth, which causes the guide rod 10 to move vertically back and forth on the connecting platform 7. The reciprocating screw 6 drives the connecting platform 7 to rotate, and the guide rod 10 causes the connecting platform 8 to rotate. This allows the mixing blade 9 to stir the collector semi-finished material, preventing adsorption between the collector semi-finished materials.

[0038] Specifically, the vacuum dehydration mechanism also includes a rotating shaft 11, a mixing blade 12, a vertical plate 13, a gear 14, and a toothed plate 15. The rotating shaft 11 is rotatably mounted on the tank body 3. It should be noted that the rotating shaft 11 and the connecting platform 8 are rotatably connected to the tank body 3 through sealed bearings, thus ensuring the sealing of the connection.

[0039] Mixing blade 12 is fixedly installed on the outside of rotating shaft 11, vertical plate 13 is fixedly installed on the bottom of sleeve plate 2, gear 14 is fixedly sleeved on the outside of rotating shaft 11, and tooth plate 15 is fixedly installed on vertical plate 13. Gear 14 meshes with tooth plate 15.

[0040] With the above structure, the rotating shaft 11 can move synchronously during the vertical reciprocating movement of the tank 3, and the toothed plate 15 can make the gear 15 rotate. In this way, the rotating shaft 11 can drive the mixing blade 12 to rotate, further agitating the semi-finished material of the collector, avoiding adsorption between the semi-finished materials of the collector, and ensuring the efficiency of vacuum dehydration of the semi-finished material of the collector.

[0041] Specifically, the vacuum dehydration mechanism also includes a hose 16, a connecting pipe 17, a vacuum pump 18, a conduit 19, and a gas storage tank 20. The hose 16 is fixedly connected to the tank 3 and the connecting pipe 17. The vacuum pump 18 and the gas storage tank 20 are both fixedly installed on the frame 1. The connecting pipe 17 is fixedly connected to the vacuum pump 18. The conduit 19 is fixedly installed between the vacuum pump 18 and the gas storage tank 20.

[0042] With the above structure, the vacuum pump 18 is started to extract the gas in the tank 3 and transport it to the gas storage tank 20 for storage.

[0043] Specifically, a through hole is provided on the side of the reciprocating screw sleeve 4, and the flexible hose 16 passes through the through hole. It should be noted that this does not affect the movement of the reciprocating screw sleeve 4.

[0044] Specifically, the sleeve 2 is slidably sleeved on the outside of the frame 1, which allows the sleeve 2 to move stably in the vertical direction.

[0045] Specifically, a semi-finished collector feed pipe is installed at the top of tank 3, and a discharge pipe is installed at the bottom of tank 3. Valves are installed on both the feed pipe and the discharge pipe to facilitate feeding and discharging.

[0046] Specifically, the second mixing blade 12 is located below the first mixing blade 9, and the top of the first connecting platform 7 is provided with a guide hole. The guide rod 10 is slidably installed in the guide hole. It should be noted that the guide rod 10 is made of high-strength steel, which allows the second connecting platform 8 to not only rotate, but also move up and down reciprocally.

[0047] Working principle:

[0048] S1: Add the collector semi-finished product through the feed pipe at the top of the tank 3, close the feed pipe valve, and then start the vacuum pump 18 on the frame 1. The vacuum pump 18 is connected to the hose 16 through the connecting pipe 17 to extract the air inside the tank 3. The extracted gas is transported to the gas storage tank 20 through the conduit 19 for temporary storage, so that a negative pressure vacuum environment is formed inside the tank 3. At the same time, the heating bushing in the jacket of the tank 3 starts to work, heating the collector semi-finished product in the tank 3, lowering the boiling point of the water in the semi-finished product, and promoting the rapid diffusion of water molecules from the inside of the material to the surface and evaporation, laying the foundation for efficient dehydration. The hose 16 passes through the through hole of the reciprocating screw sleeve 4 and can be flexibly deformed when the tank 3 moves, ensuring that the vacuum pumping process is not affected by the change of position of the tank 3.

[0049] S2: To prevent the semi-finished collector from adsorbing each other due to its wet state, thus affecting dehydration efficiency, the equipment uses a double agitation structure to disperse the material. The servo motor 5 is started, and its output drives the reciprocating screw 6 to rotate. The connecting platform 7 at the bottom of the reciprocating screw 6 rotates synchronously. Since the connecting platform 7 is slidably sleeved on the outside of the guide rod 10 at the top of the connecting platform 8, the rotation of the connecting platform 7 is transmitted to the connecting platform 8 through the guide rod 10, causing the connecting platform 8 to drive the mixing blade 9 to rotate within the tank 3, thus horizontally agitating the semi-finished product and breaking up material agglomeration. The tank 3 moves vertically back and forth under the threaded engagement of the reciprocating screw 6 and the reciprocating screw sleeve 4. The tank 3 drives the rotating shaft 11 to rise and fall synchronously. The gear 14 on the outside of the rotating shaft 11 is always meshed with the toothed plate 15 on the vertical plate 13. The gear 14 rotates as the tank 3 rises and falls, thereby driving the rotating shaft 11 and the second mixing blade 12 to rotate. The second mixing blade 12 is located below the first mixing blade 9. The two form an alternating stirring trajectory, which further disperses the semi-finished collector, avoids adsorption and agglomeration, and ensures that each material particle can fully contact the heating environment and vacuum space to accelerate the evaporation of moisture.

[0050] S3: The reciprocating spiral groove of the reciprocating screw 6 drives the reciprocating screw sleeve 4 to move vertically back and forth. The sleeve plate 2, which is fixedly connected to the reciprocating screw sleeve 4, drives the tank 3 to move up and down in sync. This reciprocating motion causes periodic shaking of the collector semi-finished product in the tank 3, causing the material to turn over in the tank. This allows the material that was originally at the bottom to move to the top, contacting more heat and vacuum areas, and avoiding uneven dehydration caused by local material standing. At the same time, the reciprocating movement of the tank 3 drives the connecting platform 2 8 to move up and down. The guide rod 10 slides synchronously in the guide hole of the connecting platform 1 7, which ensures that the rotation and stirring of the mixing blade 1 9 is not affected by the rise and fall of the tank 3, maximizes the material dispersion effect, and makes it easier for water to evaporate from the surface of the material and be drawn away by the vacuum pump 18, significantly improving the dehydration efficiency. After dehydration is completed, the valve of the discharge pipe at the bottom of the tank 3 is opened, and the processed semi-finished product can be discharged.

Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model.
