Description

Technical Field

[0001] This utility model relates to the field of phosphoric acid storage technology, and in particular to a capacitor-level phosphoric acid storage tank agitator. Background Technology

[0002] Phosphoric acid is a moderately strong acid that ionizes stepwise in aqueous solution. It exhibits the general properties of acids, reacting with bases, basic oxides, and certain salts. Capacitor-grade phosphoric acid is a high-purity phosphoric acid used in the electronics industry to produce products such as electrolytic capacitor foil. Capacitor-grade phosphoric acid should generally be stored in a relatively stable temperature environment, ideally between 5°C and 35°C. Excessively high temperatures may accelerate the chemical reaction of phosphoric acid, leading to a decrease in its purity; excessively low temperatures may cause crystallization, affecting its performance.

[0003] Stirring helps maintain a uniform temperature and concentration distribution of phosphoric acid, preventing localized supersaturation and crystallization, and ensuring the fluidity and performance of the phosphoric acid. During storage, phosphoric acid may become uneven in concentration due to various reasons; stirring ensures thorough mixing of the phosphoric acid solution. In actual storage, the diameter of the tanks used may vary, but the stirring shaft of commonly used agitators is fixed and cannot accommodate tanks of different diameters. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a capacitor-level phosphoric acid storage tank agitator, which aims to improve the problem that the agitator shaft of commonly used agitators is fixed and cannot adapt to tanks of different diameters.

[0007] Preferably, the limiting component includes a lead screw, the outer wall of which is threaded to the inside of the housing, a pin is fixedly connected to the outer wall of the lead screw, a limiting hole is formed inside the limiting ring, and the outer wall of the pin is slidably connected to the inside of the limiting hole.

[0008] Preferably, a fixed blade is fixedly connected to the outer wall of the tube shaft, a knob is rotatably connected to the inside of the tube shaft, and a first bevel gear is fixedly connected to the outer wall of the knob.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a capacitor-level phosphoric acid storage tank agitator, comprising a support frame 1. A motor 2 and a tank body 4 are mounted on the outer wall of the support frame 1. A housing 3 is fixedly mounted on the output end of the motor 2. The lower surface of the housing 3 is disposed on the upper surface of the tank body 4. A second motor 5 is fixedly connected inside the housing 3. A gear 6 is fixedly mounted on the output end of the second motor 5. A gear 7 is meshed with the tooth ends of the gear 6. A limit ring 8 is fixedly connected to the upper surface of the gear 7. The outer wall of the limit ring 8 is rotatably connected inside the housing 3. Gear 2 7 is meshed with gear 3 9. Gear 3 9 is fixedly connected to a rotating shaft 10. The bottom end of the rotating shaft 10 is rotatably connected to the inside of the outer shell 3. Gear 3 9 is meshed with a rack 11. The lower surface of the rack 11 is slidably connected to the inside of the outer shell 3. The outer wall of the rack 11 is fixedly connected to a slider 12. The lower surface of the slider 12 is fixedly connected to a tube shaft 13. The outer wall of the tube shaft 13 is slidably connected to the inside of the outer shell 3. The inside of the outer shell 3 is provided with a limit component, which is used to limit the rotation of the limit ring 8.

[0025] Specifically, the outer shell 3 and the tank 4 can be separated. By adding a lift to the support frame 1, the outer shell 3 can be lifted. The outer shell 3 can fix the second motor 5. The second motor 5 drives the second gear 7 to rotate through the first gear 6. The limiting ring 8 rotates inside the outer shell 3 and supports the rotation of the second gear 7. The second gear 7 drives the third gear 9 to rotate. The rotating shaft 10 supports the rotation of the third gear 9. The third gear 9 meshes with the rack 11. The rack 11 slides inside the outer shell 3. The inner shell 3 has a sliding groove. The rack 11 drives the tube shaft 13 to slide in the sliding groove through the slider 12.

[0026] Reference Figure 1 and Figure 2 The limiting component includes a lead screw 14, the outer wall of which is threaded to the inside of the housing 3. A pin 15 is fixedly connected to the outer wall of the lead screw 14. A limiting hole 16 is opened inside the limiting ring 8. The outer wall of the pin 15 is slidably connected to the inside of the limiting hole 16.

[0027] Specifically, rotating the lead screw 14 can cause the pin 15 to slide. When the pin 15 is inserted into the limiting hole 16, the limiting ring 8 cannot rotate, thereby restricting the gear 7 and preventing the tube shaft 13 from loosening.

[0028] Reference Figure 3 and Figure 4 A fixed blade 17 is fixedly connected to the outer wall of the tube shaft 13, and a knob 18 is rotatably connected inside the tube shaft 13. A first bevel gear 19 is fixedly connected to the outer wall of the knob 18. A second bevel gear 20 is meshed with the tooth end of the first bevel gear 19, and the outer wall of the second bevel gear 20 is rotatably connected inside the tube shaft 13.

[0029] Specifically, rotating the knob 18 causes the first bevel gear 19 to rotate, and the first bevel gear 19 meshes with the second bevel gear 20. The tube shaft 13 supports the rotation of the second bevel gear 20.

[0030] Reference Figure 3 and Figure 4 The lower surface of the second bevel gear 20 is fixedly connected to a lead screw 21, and the outer wall of the lead screw 21 is threadedly connected to a sliding frame 22; the outer wall of the sliding frame 22 is provided with a limit block 23, which is slidably connected to the inside of the tube shaft 13; the outer wall of the sliding frame 22 is fixedly connected to a sliding blade 24, and the outer wall of the sliding blade 24 is slidably connected to the inside of the fixed blade 17 and the tube shaft 13.

[0031] Specifically, the rotation of the second bevel gear 20 drives the second lead screw 21 to rotate, the second lead screw 21 pushes the sliding frame 22 to slide, the limiting block 23 restricts the sliding frame 22 to slide, the sliding frame 22 drives the sliding blade 24 to slide, the sliding blade 24 slides inside the fixed blade 17, thereby changing the length of the blade. The longer the blade, the greater the volume and force of the phosphoric acid pushed during rotation, the higher the stirring intensity, which can effectively break the concentration gradient and temperature gradient in phosphoric acid and accelerate the mixing and heat and mass transfer process. When it is necessary to reduce the stirring intensity, avoid excessive stirring from affecting the properties of phosphoric acid, or prevent phosphoric acid splashing, the blade can be shortened appropriately.

[0032] Reference Figure 4 A baffle 25 is fixedly connected to the lower surface of the sliding blade 24, and the outer wall of the baffle 25 is attached to the inner wall of the tube shaft 13.

[0033] Specifically, when the sliding blade 24 retracts, the groove of the tube shaft 13 will be exposed to form an opening. The sliding blade 24 drives the baffle 25 to slide, and the baffle 25 can block the opening of the tube shaft 13 to prevent the capacitor-stage phosphoric acid from entering the interior of the tube shaft 13 and cooperating with the internal parts.

[0034] Working principle: When using this mixer, rotating the lead screw 14 pulls the pin 15 out of the limiting hole 16, starting the gear 6 at the bottom output end of the motor 2 5. Gear 6 drives gear 2 7 to rotate, and gear 2 7 and the limiting ring 8 rotate simultaneously. Gear 2 7 drives multiple gears 3 9 to rotate, and gears 3 9 push the rack 11 to slide. The rack 11 drives the tube shaft 13 to slide through the slider 12, thereby adjusting the position of the tube shaft 13 for easy placement into different containers 4. By rotating the lead screw 14 in the opposite direction, the pin 15 is inserted into the limiting hole 16, and the limiting ring 8 is fixed. Starting the motor 2 allows the mixer to start moving. The stirring is performed. When the stirring intensity needs to be adjusted, the first bevel gear 19 is rotated by turning the knob 18. The first bevel gear 19 drives the second screw 21 to rotate through the second bevel gear 20. The second screw 21 pushes multiple sliding frames 22 to rise and slide. The sliding frames 22 drive the sliding blades 24 to retract into the fixed blades 17, thereby reducing the length of the stirring blades. When the sliding blades 24 slide, they drive the baffle 25 to slide, which can prevent the capacitor-grade phosphoric acid from entering the interior of the tube shaft 13. This stirrer can not only adjust the position of the tube shaft 13 to adapt to different tanks 4, but also adjust the length of the blades, thereby changing the stirring intensity.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
