Description

Technical Field

[0001] This utility model relates to the field of stirring equipment technology, specifically a highly dispersed nano zinc oxide stirring equipment. Background Technology

[0002] Nano zinc oxide, with its high specific surface area, high chemical activity, and excellent optical, catalytic, and antibacterial properties, has demonstrated outstanding application value in numerous fields such as rubber, coatings, ceramics, textiles, and electronics. In its processing, stirring is a crucial step, playing a decisive role in product performance and quality.

[0003] Utility model patent application number CN202322864098.2 discloses an enteric-coated nano-zinc oxide production device. This device includes a drying and mixing tank; a scraping column positioned on one side of the inner wall of the drying and mixing tank, with a scraping component on its outer side; and a transmission component positioned at the bottom of the mixing column and the scraping column. This utility model provides an enteric-coated nano-zinc oxide production device that, through the structural design of the scraping component and the scraping column, facilitates the scraping of nano-zinc oxide adhering to the inner wall of the drying and mixing tank, mixing it into the center of the tank for thorough mixing. This prevents uneven mixing of nano-zinc oxide at the edges of the inner wall, thus ensuring sufficient mixing. It also ensures uniform and sufficient heating of the drying and mixing tank, preventing insufficient heating of the inner wall and improving the heating effect of the nano-zinc oxide, further enhancing the device's effectiveness and improving the drying and mixing efficiency of the nano-zinc oxide.

[0004] Although the enteric-coated nano-zinc oxide production equipment ensures effective mixing of nano-zinc oxide, the following problems exist in practical use: The equipment uses independently designed mixing blades to stir the material. However, during the preparation of the nano-zinc oxide material, when the material exhibits high viscosity, the shear force and disturbance range of a single mixing blade are limited, resulting in insufficient uniformity of the flow field within the material. Consequently, the nano-zinc oxide particles within the material are difficult to fully disperse, failing to meet the process requirements for high dispersion. Therefore, we propose a high-dispersion nano-zinc oxide mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a highly dispersed nano zinc oxide stirring device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The mixing tank has an open top; a first motor is installed at the bottom of the mixing tank.

[0009] The lid is detachably mounted on the top of the mixing tank; a second motor is mounted on the top of the lid.

[0010] A dispersion assembly, installed inside a mixing tank and used for the dispersion of nano-zinc oxide; comprising a first rotating shaft, a housing, and a second stirring shaft arranged sequentially from top to bottom;

[0011] The first rotating shaft is coaxially keyed to the output shaft of the second motor, and the first stirring blade is coaxially keyed to the outer wall of the first rotating shaft.

[0012] The shell is hollow, and the top of the shell is coaxially fixed to the bottom of the first rotating shaft. A drive shaft is rotatably installed inside the shell, and the bottom of the drive shaft passes through the shell and has a drive groove. The shell also has a first bevel gear coaxially keyed to the drive shaft. Multiple second bevel gears mesh above the first bevel gear. A third rotating shaft is coaxially keyed to each of the second bevel gears. The third rotating shaft passes through the shell and is rotatably connected to the shell. Multiple third stirring blades are coaxially keyed to the outer wall of the third rotating shaft.

[0013] The second stirring shaft is coaxially keyed to the output shaft of the first motor. The outer wall of the second stirring shaft is coaxially keyed to the second stirring blade. The top of the second stirring shaft is coaxially fixed with a transmission block that is inserted into the transmission groove.

[0014] As a preferred technical solution of this utility model, a discharge pipe is fixed at one side of the bottom of the mixing tank, and a plug is threadedly connected to the bottom of the discharge pipe;

[0015] This setting facilitates material discharge via the discharge pipe.

[0016] As a preferred technical solution of this utility model, a feed pipe is fixed on one side of the top of the cover, and a sealing cap is threadedly connected to the feed pipe.

[0017] In this configuration, the feed pipe facilitates the addition of raw materials to the mixing tank.

[0018] As a preferred technical solution of this utility model, the cover and the mixing tank are fixedly connected by bolts, and a sealing rubber ring is used to seal the cover and the mixing tank.

[0019] As a preferred technical solution of this utility model, the bottom end of the first rotating shaft is fixedly connected to the housing by multiple bolts, and the first rotating shaft is a product made of alloy steel.

[0020] In this configuration, the design ensures a secure connection between the first rotating shaft and the housing 31.

[0021] As a preferred technical solution of this utility model, a plurality of second bevel gears are distributed in a ring with equal spacing around the first bevel gear as the center, and the second bevel gears are formed by gear hobbing process;

[0022] This design ensures the operational stability of the distributed components.

[0023] As a preferred technical solution of this utility model, the second stirring shaft and the transmission block are integrally formed, and the cross-sectional shape of the transmission block and the transmission groove are both regular hexagonal.

[0025] As a preferred technical solution of this utility model, the first rotating shaft and the second stirring shaft are located on the same vertical axis, and the rotation direction of the first rotating shaft is opposite to the rotation direction of the second stirring shaft;

[0026] In this configuration, the design enhances the shearing and mixing effect on the material and increases the dispersion effect on nano zinc oxide.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. The dispersion assembly consists of a first rotating shaft, a second stirring shaft, and multiple third rotating shafts, each equipped with stirring blades. During operation, the stirring blades on different shafts rotate simultaneously, subjecting the material in the mixing tank to forces from multiple directions. The first rotating shaft drives the first stirring blades to rotate, generating a circular flow field centered on the first rotating shaft. The second stirring shaft drives the second stirring blades to rotate, creating another circular flow field in a different direction. The rotation of the third stirring blades on the multiple third rotating shafts further increases the complexity of the flow field. This complex flow field ensures that the highly viscous nano-zinc oxide material is sufficiently agitated in all directions, avoiding the problem of insufficient local mixing caused by a single stirring blade creating only a simple flow field.

[0029] 2. Simultaneously, the first rotating shaft and the second stirring shaft rotate in opposite directions, which causes the material between them to be subjected to opposite forces, generating strong shearing and stretching effects within the material. This effect effectively breaks up the agglomerates between the nano-zinc oxide particles, making the particles more uniformly dispersed in the material. This design further enhances the dispersion effect of the nano-zinc oxide material. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0040] This embodiment provides a technical solution:

[0041] Please see Figure 1 As shown, a highly dispersed nano zinc oxide stirring device includes a stirring tank 1 with an open top; a first motor 10 is installed at the bottom of the stirring tank 1; a cover 2 is detachably installed on the top of the stirring tank 1; and a second motor 21 is installed on the top of the cover 2.

[0042] The above-described configuration of the mixing tank 1 and the cover 2 facilitates mixing and processing within the mixing tank 1.

[0043] Please see Figure 1As shown, in this embodiment, a discharge pipe 11 is fixed to one side of the bottom of the mixing tank 1, and a plug is threaded to the bottom of the discharge pipe 11. This design facilitates the discharge of materials after mixing, and the threaded connection of the plug facilitates disassembly and installation, allowing for flexible control of the discharge process and improving the ease of use of the equipment. A feed pipe 20 is fixed to one side of the top of the cover 2, and a sealing cap is threaded to the feed pipe 20. This facilitates the addition of materials during mixing, while the sealing cap effectively prevents material splashing and the entry of external impurities.

[0044] In this embodiment, the cover 2 and the mixing tank 1 are fixedly connected by bolts, and a sealing rubber ring is used to seal the cover 2 and the mixing tank 1. This connection method not only makes the cover 2 securely installed, but also the sealing rubber ring can effectively prevent material leakage during the mixing process, ensuring the equipment's airtightness, while also facilitating disassembly and maintenance.

[0045] In this setup, the bolt fixing method not only provides a secure connection but also offers the advantage of easy assembly and disassembly.

[0046] Please see Figures 1-5 As shown, the dispersion component 3 is installed inside the mixing tank 1 and is used for the dispersion of nano-zinc oxide; it includes a first rotating shaft 30, a housing 31, and a second stirring shaft 32 arranged sequentially from top to bottom; the first rotating shaft 30 is coaxially keyed to the output shaft of the second motor 21, and a first stirring blade 300 is coaxially keyed to the outer wall of the first rotating shaft 30; the housing 31 is hollow, and the top of the housing 31 is coaxially fixed to the bottom end of the first rotating shaft 30; a transmission shaft 33 is rotatably mounted inside the housing 31, and the bottom end of the transmission shaft 33 passes through the housing 31 and has a transmission groove 330; the housing 31 also has a transmission groove 330. The first bevel gear 34 is coaxially keyed to the moving shaft 33. Multiple second bevel gears 35 mesh above the first bevel gear 34. A third rotating shaft 36 is coaxially keyed to each of the second bevel gears 35. The third rotating shaft 36 passes through the housing 31 and is rotatably connected to the housing 31. Multiple third stirring blades 37 are coaxially keyed to the outer wall of the third rotating shaft 36. The second stirring shaft 32 is coaxially keyed to the output shaft of the first motor 10. A second stirring blade 320 is coaxially keyed to the outer wall of the second stirring shaft 32. A transmission block 321 that is inserted into and cooperates with the transmission groove 330 is coaxially fixed to the top of the second stirring shaft 32.

[0047] With the above configuration, the first rotating shaft 30 is coaxially connected to the second motor 21, driving the first stirring blade 300 to rotate; the second stirring shaft 32 is also connected to the second motor 21 to drive the second stirring blade 320. At the same time, the transmission structure of the first bevel gear 34, the second bevel gear 35, the third rotating shaft 36, and the third stirring blade 37 in the housing 31 realizes multi-dimensional and multi-level stirring, effectively improving the dispersion efficiency and uniformity of nano zinc oxide.

[0048] In this embodiment, the bottom end of the first rotating shaft 30 is fixedly connected to the housing 31 by multiple bolts. The first rotating shaft 30 is made of alloy steel. The bolt fixing method ensures a firm and reliable connection, and the alloy steel material gives the first rotating shaft 30 high strength and good wear resistance, improving the overall stability and service life of the equipment.

[0049] Please see Figures 4-5 As shown, in this embodiment, multiple second bevel gears 35 are distributed in a ring with equal spacing around the first bevel gear 34 as the center. The second bevel gears 35 are formed by gear hobbing. The ring-shaped equal spacing ensures the uniformity and stability of the transmission. The high-precision gears produced by gear hobbing can effectively reduce transmission errors, improve transmission efficiency, and ensure the stable operation of the dispersion component 3.

[0050] In this embodiment, the second stirring shaft 32 and the transmission block 321 are integrally formed, and the cross-sectional shape of both the transmission block 321 and the transmission groove 330 is a regular hexagon. The integrally formed structure enhances the connection strength between the second stirring shaft 32 and the transmission block 321, while the regular hexagonal transmission block 321 and the transmission groove 330 cooperate to achieve precise transmission, avoid slippage, and improve power transmission efficiency.

[0051] In this embodiment, the first rotating shaft 30 and the second stirring shaft 32 are located on the same vertical axis, and the rotation direction of the first rotating shaft 30 is opposite to that of the second stirring shaft 32. This design creates opposing stirring force fields inside the mixing tank 1, enhancing the shearing and mixing effect on the materials, effectively breaking up material agglomeration, and further improving the dispersion uniformity of nano zinc oxide.

[0052] It should be noted that O-rings are installed where the drive shaft 33 passes through the housing 31 and where the third rotating shaft 36 passes through the housing 31. During the mixing process of nano-zinc oxide, the material inside the mixing tank may have a certain degree of fluidity and pressure. The O-rings can tightly fit the connection between the drive shaft 33, the third rotating shaft 36 and the housing 31, forming an effective sealing barrier to prevent the highly viscous nano-zinc oxide material from leaking into the housing 31 through these gaps. This helps to maintain the stability of the quantity and concentration of the material inside the mixing tank, ensuring the continuity and consistency of the mixing process, thereby guaranteeing the dispersion effect of nano-zinc oxide and product quality.

[0053] It is worth noting that the first motor 10 and the second motor 21 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0054] In practical use, firstly, the user injects nano zinc oxide and other materials into the top-opening mixing tank 1 through the feed pipe 20 at the top of the cover 2, and tightens the sealing cap at the feed pipe 20 to prevent material splashing and external impurities from entering. Then, the user starts the first motor 10 and the second motor 21. The first motor 10 and the second motor 21 start working. The first motor 10 drives the second stirring shaft 32 to rotate, which drives the second stirring blade 320 to stir the lower layer of materials in the mixing tank 1. At the same time, the second motor 21 drives the first rotating shaft 30 to rotate, so that the first stirring blade 300 stirs the upper layer of materials. Since the transmission block 321 and the transmission groove 330 are hexagonally inserted and matched, the power is transmitted to the transmission shaft 33, which in turn drives the first bevel gear 34, which is coaxial with the transmission shaft 33, to rotate. Since multiple second bevel gears 35 mesh with the first bevel gear 34, the second bevel gears 35 can also drive the third rotating shaft 36 and the third stirring blade 37 to rotate, realizing multi-layer and multi-directional stirring.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
