Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a vacuum moisture-proof mixing tank for ferrite powder. Background Technology

[0002] Ferrite powders have wide applications in electronics, communications, and other fields. The uniformity and moisture resistance during the mixing process are crucial to the quality of the final product. However, most existing mixing tanks use ordinary sealed structures, making it difficult to maintain a vacuum environment inside for extended periods. External air and moisture easily penetrate the tank, causing oxidation and hydrolysis of the ferrite powder, thereby reducing its magnetic permeability and performance.

[0003] A search revealed a bottom-stirring tank with publication number CN102836687B, published on January 13, 2016. This patent improves sealing performance and reduces shaft sway by incorporating a modular mechanical seal and self-aligning bearing at the bottom of the reactor, thus preventing leaks. However, while this technical solution improves sealing performance, its sealing structure cannot maintain a vacuum environment inside the tank for extended periods. Especially during stirring, pressure changes within the tank allow external moisture to seep in, affecting the moisture-proof effect of the ferrite powder. Furthermore, this structure places high demands on the material and machining precision of the sealing components, potentially increasing production costs.

[0004] A search revealed an asphalt heating and mixing tank with publication number CN113648913B, published on June 7, 2024. This patent, by setting up a gas containment tank and a single-chip microcomputer control system, enables centralized batch treatment of exhaust gas, reducing the energy consumption of the air purification device. However, while this technical solution optimizes exhaust gas treatment, its sealing structure design does not fully consider the stringent vacuum environment requirements of ferrite powder during mixing. The design of the exhaust port and air inlet pipe at the top of the tank may allow outside air and moisture to enter the tank during mixing, affecting the moisture-proof performance of the powder. Furthermore, this structure is highly dependent on pressure sensors and the single-chip microcomputer, potentially increasing the complexity of the equipment and the difficulty of maintenance.

[0005] The aforementioned problems indicate that existing mixing tanks still have certain shortcomings in maintaining a vacuum environment, preventing moisture infiltration, and simplifying structural design. Therefore, this invention provides a vacuum moisture-proof mixing tank for ferrite powder, aiming to optimize the sealing structure, ensure a long-term vacuum environment inside the tank, reduce the infiltration of external moisture, thereby improving the moisture-proof performance and magnetic permeability stability of the ferrite powder, and meeting the demand for high-quality ferrite powder in the electronics and communications fields. Utility Model Content

[0006] This invention provides a vacuum moisture-proof mixing tank for ferrite powder, which solves the problem mentioned in the background art that existing mixing tanks mostly adopt ordinary sealing structures, making it difficult to maintain a vacuum environment inside the tank for a long time, and allowing outside air and moisture to easily penetrate into the tank.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A vacuum moisture-proof mixing tank for ferrite powder includes an adjustment mechanism, an auxiliary mechanism, and a mixing mechanism. The adjustment mechanism includes a base, with connecting frames fixedly installed on both sides of the base. A mixing tank is fixedly installed on the outer side of each connecting frame. A discharge pipe is installed at the center of the bottom of each mixing tank. A turntable is rotatably connected to the upper surface of the base. The auxiliary mechanism includes a hydraulic telescopic rod, with its bottom end fixedly connected to the top of the turntable. A crossbar is fixedly installed at the upper end of the hydraulic telescopic rod, and a vacuum pump is fixedly installed on one side of the upper end of the crossbar. A fixing rod is fixedly installed at the bottom of the crossbar at the axis of the mixing tank. The mixing mechanism includes a sealing cover, with a transmission box fixedly installed at the center of the upper end of the sealing cover. The top of the transmission box is connected to the bottom of the fixing rod. A vacuum filter is fixedly installed on one side of the upper end of the sealing cover. The top of the vacuum filter is connected to the input end of the pipeline vacuum pump, and the bottom of the vacuum filter extends through the sealing cover to the bottom.

[0009] Furthermore, a first stirring shaft is rotatably connected to the bottom center of the sealing cover, and a second stirring shaft is rotatably connected inside the first stirring shaft. The upper ends of both the first and second stirring shafts extend into the interior of the transmission box.

[0010] Furthermore, a first bevel gear is fitted onto the upper end of the first stirring shaft, and a second bevel gear is fitted onto the upper end of the second stirring shaft.

[0011] Furthermore, a third bevel gear is rotatably connected to the inner side of the transmission box, and the first bevel gear, the second bevel gear, and the third bevel gear mesh with each other.

[0012] Furthermore, a speed reducer is fixedly installed on one side of the transmission box, and the output end of the speed reducer is connected to the third bevel gear.

[0014] Furthermore, the bottom central shaft of the turntable extends through the base into the interior and is fitted with a worm gear.

[0015] Furthermore, a second servo motor is fixedly installed at the upper interior of the base, and a worm gear is sleeved on the output end of the second servo motor, with the worm gear meshing with the worm wheel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention features a base for the adjusting mechanism providing stable support, a connecting frame securing the mixing tank, a discharge pipe facilitating powder discharge, and a turntable that drives a hydraulic telescopic rod for rotation. This allows the mixing mechanism to adjust its direction while one mixing tank is discharging, enabling it to utilize the other tank for mixing, significantly improving production efficiency. The auxiliary mechanism's hydraulic telescopic rod adjusts the height of the crossbar, thus adjusting the position of the mixing mechanism. A vacuum pump removes air from the mixing tank to create a vacuum environment, and a fixed rod connects to the transmission box. The sealing cover of the mixing mechanism, in conjunction with the mixing tank, forms a sealed space, preventing moisture from the outside air from affecting the powder. A vacuum filter filters the powder during air extraction, facilitating later centralized cleaning and preventing damage to the vacuum pump. These three components work together to achieve mixing of ferrite powder in a vacuum and moisture-proof environment, ensuring powder quality. The first mixing shaft at the bottom of the sealing cover and the second mixing shaft inside form a dual-shaft mixing structure, enabling different mixing trajectories and effects. The first and second mixing shafts can rotate in different directions, enhancing the mixing degree of the ferrite powder and resulting in more uniform powder mixing. Attached Figure Description

[0027] Example

[0028] Please see Figure 1-5This utility model provides a vacuum moisture-proof mixing tank for ferrite powder, including an adjustment mechanism 1, an auxiliary mechanism 2, and a mixing mechanism 3. The adjustment mechanism 1 includes a base 4, with connecting frames 5 fixedly installed on both sides of the base 4. A mixing tank 6 is fixedly installed on the outer side of the connecting frames 5. A discharge pipe 7 is installed at the center of the bottom end of the mixing tank 6. A turntable 20 is rotatably connected to the upper end of the base 4. The auxiliary mechanism 2 includes a hydraulic telescopic rod 8, with the bottom end of the hydraulic telescopic rod 8 fixedly connected to the top end of the turntable 20. A crossbar 9 is fixedly installed at the upper end of the hydraulic telescopic rod 8. A vacuum pump 10 is fixedly installed on one side of the upper end of the crossbar 9. A fixing rod 18 is fixedly installed at the bottom end of the crossbar 9 at the axis position of the mixing tank 6. The mixing mechanism 3 includes a sealing cover 11, with a transmission box 19 fixedly installed at the center of the upper end of the sealing cover 11. The top end of the transmission box 19 is connected to the bottom end of the fixing rod 18. A vacuum filter 13 is fixedly installed on one side of the upper end of the sealing cover 11. The top end of the vacuum filter 13 is connected to the input end of the vacuum pump 10 through a pipeline. The bottom end of the vacuum filter 13 extends through the sealing cover 11 to the bottom. The base 4 of the adjusting mechanism 1 provides stable support. The connecting frame 5 fixes the mixing tank 6. The discharge pipe 7 facilitates the discharge of powder. The turntable 20 can drive the hydraulic telescopic rod 8 to rotate. Thus, when one of the mixing tanks 6 is discharging, the direction of the mixing mechanism 3 can be adjusted so that it can use the other mixing tank 6 for mixing operations, which greatly improves the production efficiency of the enterprise. The hydraulic telescopic rod 8 of the auxiliary mechanism 2 can adjust the height of the crossbar 9, thereby adjusting the position of the mixing mechanism 3. The vacuum pump 10 is used to remove air from the mixing tank 6 to form a vacuum environment. The fixed rod 18 connects to the transmission box 19. The sealing cover 11 of the mixing mechanism 3 cooperates with the mixing tank 6 to form a sealed space to prevent moisture in the outside air from affecting the powder. The vacuum filter 13 filters the powder during the air extraction, which is convenient for centralized cleaning later and also avoids damage to the vacuum pump 10. The three work together to realize the mixing of ferrite powder in a vacuum and moisture-proof environment, ensuring the quality of the powder.

[0029] A first stirring shaft 16 is rotatably connected to the center of the bottom end of the sealing cover 11. A second stirring shaft 17 is rotatably connected inside the first stirring shaft 16. The upper ends of both the first stirring shaft 16 and the second stirring shaft 17 extend into the interior of the transmission box 19. The first stirring shaft 16 at the bottom end of the sealing cover 11 and the second stirring shaft 17 inside form a dual-shaft stirring structure, which can achieve different stirring trajectories and stirring effects. The first stirring shaft 16 and the second stirring shaft 17 can rotate in different directions to enhance the stirring and mixing degree of the ferrite powder and make the powder more uniformly mixed.

[0030] A first bevel gear 26 is fitted onto the upper end of the first stirring shaft 16, and a second bevel gear 24 is fitted onto the upper end of the second stirring shaft 17. The first bevel gear 26 and the second bevel gear 24 fitted onto the upper ends of the first stirring shaft 16 and the second stirring shaft 17 provide a connection basis for power transmission within the transmission box 19, enabling the power of the first servo motor 15 to be transmitted to the first stirring shaft 16 and the second stirring shaft 17 respectively, thereby realizing the power transmission of dual-shaft stirring.

[0031] A third bevel gear 25 is rotatably connected to the inner side of the transmission box 19. The first bevel gear 26, the second bevel gear 24, and the third bevel gear 25 mesh with each other. The third bevel gear 25 inside the transmission box 19 meshes with the first bevel gear 26 and the second bevel gear 24, decomposing the power transmitted by the first servo motor 15 through the reducer 14 into power to drive the first stirring shaft 16 and the second stirring shaft 17 to rotate. The direction of power transmission can be changed, causing the first stirring shaft 16 and the second stirring shaft 17 to rotate in different directions, thus improving the stirring effect. The first stirring shaft 16 is rotatably connected to the sealing cover 11 via bearings, and the second stirring shaft 17 passes through the top of the transmission box 19 and is rotatably connected to the top of the transmission box 19 via bearings.

[0032] A reducer 14 is fixedly installed on one side of the transmission box 19. The output end of the reducer 14 is connected to the third bevel gear 25. A first servo motor 15 is fixedly installed on one side of the reducer 14. The output end of the first servo motor 15 is connected to the input end of the reducer 14. The first servo motor 15 provides power to the third bevel gear 25 through the reducer 14. The reducer 14 can reduce the speed and increase the torque, so that the first stirring shaft 16 and the second stirring shaft 17 can obtain appropriate speed and torque for stirring operations, ensuring the stability and efficiency of stirring.

[0033] A vacuum pressure gauge 27 is inserted into one side of the upper end of the sealing cover 11, and a sealing gasket 12 is installed at the outer edge of the bottom end of the sealing cover 11. The vacuum pressure gauge 27 on the sealing cover 11 can monitor the vacuum level in the mixing tank 6 in real time, so that the operator can grasp the vacuum status in the tank and adjust the operation of the vacuum pump 10 in time. The sealing gasket 12 ensures the sealing between the sealing cover 11 and the mixing tank 6, prevents outside air from entering, maintains the vacuum and moisture-proof environment in the tank, and ensures that the quality of the ferrite powder is not affected.

[0034] The bottom center shaft of the turntable 20 extends through the base 4 and is fitted with a worm gear 21. The worm gear 21 at the bottom of the turntable 20 cooperates with the worm 23 in the base 4 to provide a transmission structure for the rotation of the turntable 20, so that the power of the second servo motor 22 can be transmitted to the turntable 20, and the turntable 20 can rotate smoothly.

[0035] A second servo motor 22 is fixedly installed at the upper part of the base 4. A worm gear 23 is sleeved on the output end of the second servo motor 22. The worm gear 23 meshes with the worm wheel 21. The second servo motor 22 in the base 4 drives the turntable 20 to rotate through the meshing of the worm gear 23 and the worm wheel 21, which in turn drives the hydraulic telescopic rod 8 to rotate, so that the stirring mechanism 3 can be used alternately between a pair of stirring tanks 6 to improve production efficiency.

[0036] Specifically, the working principle of this ferrite powder vacuum moisture-proof mixing tank is as follows: First, the second servo motor 22 is started. Its output worm gear 23 meshes with the worm wheel 21 at the bottom of the turntable 20, driving the turntable 20 to rotate. This adjusts the mixing mechanism 3 above one of the mixing tanks 6. Then, the hydraulic telescopic rod 8 extends and retracts to adjust the height of the crossbar 9, ensuring a tight fit between the sealing cover 11 and the mixing tank 6. The sealing gasket 12 ensures a sealing effect. Subsequently, the vacuum pump 10 extracts air from the mixing tank 6 through the vacuum filter 13. The vacuum pressure gauge 27 monitors the vacuum level inside the tank in real time. Once the required vacuum environment is reached, the first servo motor 15 starts. After the speed is reduced and the torque is increased by the reducer 14, it drives the third bevel gear 25 to rotate. The third bevel gear 25 meshes with the first bevel gear 26 and the second bevel gear 24, transmitting power to the first stirring shaft 16 and the second stirring shaft 17 respectively, causing them to rotate in different directions to perform dual-shaft stirring of the ferrite powder, ensuring uniform mixing. After stirring is completed, the hydraulic telescopic rod 8 raises the stirring mechanism 3, and the turntable 20 rotates to switch the stirring mechanism 3 to the top of another stirring tank 6, repeating the above operation. At the same time, the stirring tank 6, which has completed stirring, can discharge the powder through the discharge pipe 7. Throughout the process, the adjusting mechanism 1, the auxiliary mechanism 2, and the stirring mechanism 3 work together to complete the ferrite powder stirring task in a vacuum and moisture-proof environment, improving production efficiency and powder quality.
