Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0042] like Figures 1-7The present invention provides a specific embodiment of a compact horizontal powder mixing device, comprising a base 1, a mounting frame 2 fixedly mounted on the base 1, a stirring motor 3 horizontally mounted on the mounting frame 2, a stirring shaft 5 connected to the output shaft of the stirring motor 3 via a transmission assembly 4, a stirring assembly 6 mounted on the stirring shaft 5, and a horizontal mixing tank 7 mounted on one side of the mounting frame 2. The mounting frame 2 is arranged to form a first mounting cavity 8 and a second mounting cavity 9 arranged side by side. The stirring shaft 5 is horizontally mounted on the mounting frame 2 via a bearing assembly 10, and the axis of the stirring shaft 5 is parallel to the axis of the output shaft of the stirring motor 3, both being horizontally positioned. Both the stirring motor 3 and the stirring shaft 5 are located within the first mounting cavity 8, with the stirring motor 3 positioned above or below the stirring shaft 5. The transmission assembly 4 is located within the second mounting cavity 9.

[0043] like Figure 2 As shown, in this invention, the stirring shaft 5, which is directly connected to the stirring assembly 6, and the stirring motor 3, which drives the stirring shaft 5 to rotate, are positioned vertically in the same mounting cavity. The two are connected by a transmission assembly 4 installed in another mounting cavity. This is equivalent to "folding" the stirring motor 3 and stirring shaft 5, which are arranged in a straight line in the prior art, into two parts, and then connecting the folded stirring motor 3 and stirring shaft 5 through the transmission assembly 4. This invention greatly reduces the driving space of the horizontal stirring device, reduces the overall volume of the mixing device, and requires less installation space and floor area, thus having high applicability.

[0044] like Figure 3 As shown, the mounting bracket 2 in this embodiment includes: a frame 21 fixedly mounted on the base 1; a first mounting plate 22, a second mounting plate 23, and a third mounting plate 24 fixedly mounted on the frame 21 from right to left; and front and rear mounting plates 25 and an upper top plate 26 mounted on the frame 21. The second mounting plate 23 has a through hole 27 connecting the first mounting cavity 8 and the second mounting cavity 9. At least one heat dissipation component 28 is provided on the upper top plate 26 corresponding to the first mounting cavity 8 and / or the second mounting cavity 9. In this embodiment, a heat dissipation component 28 is provided on the upper top plate 26 corresponding to the first mounting cavity 8 and / or the second mounting cavity 9.

[0045] Specifically, the heat dissipation assembly 28 includes a heat dissipation fan mounted on the inner wall of the upper top plate 26 and a heat dissipation window opened on the upper top plate 26. During installation, the air outlet of the heat dissipation fan corresponds to the heat dissipation window. In this embodiment, a through hole 27 for air circulation is opened on the second mounting plate 23 between the first mounting cavity 8 and the second mounting cavity 9, so that the heat dissipation assembly 28 can be installed on the top of the first mounting cavity 8 or the top of the second mounting cavity 9, so that the components inside the two cavities can be cooled simultaneously.

[0046] To enable the stirring shaft 5 to pass sequentially through the second mounting plate 23 and the first mounting plate 22, and to rotate simultaneously on the first mounting plate 22 and the second mounting plate 23, the bearing assembly 10 in this embodiment includes a bearing seat 101 with both ends fixedly mounted to the first mounting plate 22 and the second mounting plate 23, and a first bearing 102 and a second bearing 103 arranged sequentially from left to right inside the bearing seat 101. See details... Figure 5 and Figure 6 .

[0047] To prevent powder from entering the bearing housing 101 and affecting the rotation between the first bearing 102, the second bearing 103, and the stirring shaft 5, such as... Figure 5 and Figure 6 As shown, in this embodiment, the sealing assembly 20 between the first mounting plate 22 and the first bearing 102 specifically includes a dry gas sealing seat 201 fixedly installed on the left side of the bearing seat 101, a cover plate 202 covering the right side of the dry gas sealing seat 201, a first sealing cavity 203, a second sealing cavity 204, an air inlet 205, and an air outlet 206. The stirring shaft 5, the dry gas sealing seat 201, and the cover plate 202 together form the first sealing cavity 203. The second sealing cavity 204 is provided between the cover plate 202 and the first bearing 102. The air outlet 206 is opened on the bearing seat 101 and connects to the second sealing cavity 204. 4. The air passage is connected. The air inlet 206 is opened on the bearing seat 101 and the dry air sealing seat 201. The air inlet 205 is connected to the first sealing cavity 203 and to the external air source passage. In the first sealing cavity 203, from right to left, the first push ring 207, the first stationary ring 208, the moving ring 209, the second stationary ring 2010 and the second push ring 2011 are arranged sequentially. The first push ring 207, the first stationary ring 208, the moving ring 209, the second stationary ring 2010 and the second push ring 2011 are all sleeved on the stirring shaft 5. The moving ring 209 rotates with the stirring shaft 5. The first stationary ring 208 and the second stationary ring 2010 are clearance-fitted with the stirring shaft 5.

[0048] Specifically, the horizontal mixing tank 7 is installed on the first mounting plate 22. The first stationary ring 208 and the second stationary ring 2010 are respectively installed on the left and right sides of the moving ring 209. The first push ring 207 and the second push ring 2011 are respectively set on the left and right sides of the corresponding stationary rings. During installation, in order to connect the mixing shaft 5 with the power mechanism and the mixing assembly 6, the mixing shaft 5 passes through the cover plate 202 and the dry gas sealing seat 201. An air inlet 205 is provided at the joint between the bearing seat 101 and the dry gas sealing seat 201. One end of the air inlet 205 is connected to the first sealing cavity 203, and the other end is connected to an external air source through an air pipe. An air outlet 206 is provided on the bearing seat 101, and clean gas is injected into the first sealing cavity 203 through the external air source.

[0049] During use, if the air inlet 205 is not inflated, when the power mechanism is started, the moving ring 209 rotates with the stirring shaft 5, while the first stationary ring 208 and the second stationary ring 2010 remain stationary. Under high-speed rotation, friction will occur between the moving ring 209 and the first stationary ring 208, and between the moving ring 209 and the second stationary ring 2010. This friction generates high temperatures, affecting the service life of each component. However, when the air inlet 205 is inflated, gas is introduced into the air inlet 205, which connects to the first sealing cavity 203 and is also connected to the external air source. Inside the first sealing cavity 203, a stable gas film is formed on the contact surfaces between the first stationary ring 208 and the moving ring 209, and between the second stationary ring 2010 and the moving ring 209. On the one hand, this effectively prevents powder from leaking into the bearings, avoiding corrosion of the equipment and increasing friction between parts, thus reducing the service life of the equipment. On the other hand, it prevents powder leakage, ensuring the accuracy of the formula ratio and effectively improving the mixing effect.

[0050] In this embodiment, the thickness of the gas film formed is between a few micrometers and tens of micrometers, ensuring that the moving ring 209 and the first stationary ring 208 and the second stationary ring 2010 do not directly contact each other. The presence of the gas film reduces friction and wear, extending the service life of the equipment. On the other hand, it can prevent powder leakage, further ensuring the accuracy of the formula ratio and effectively improving the mixing effect. The gas film not only plays a lubricating role but also effectively prevents process gas leakage. Gas flows from the high-pressure side (process gas side) to the low-pressure side (atmospheric side), but due to the barrier of the gas film, the leakage is very small. During operation, the thickness and pressure distribution of the gas film are dynamically adjusted to adapt to changes in speed, pressure, and temperature. This dynamic balance ensures the stability and reliability of the seal. The dry gas seal achieves non-contact sealing by forming a stable gas film, which is highly efficient, reliable, and environmentally friendly. By forming a stable gas film, a high-pressure side is formed inside the sealing seat, which can effectively prevent material leakage in the hopper, prevent powder backflow and leakage, and prevent powder leakage from corroding the equipment. During stirring, a slight positive pressure is formed in the hopper, making it difficult for external gas and water to enter the hopper and avoiding contamination of the material.

[0051] In a preferred embodiment, the transmission assembly 4 is disposed within the second mounting cavity 9. The transmission assembly 4 includes a first pulley 41 coaxially arranged with the output shaft of the drive motor, a second pulley 42 coaxially arranged with the stirring shaft 5, a transmission protective cover 44 fixedly mounted on the outer wall of the second mounting plate 23, and heat dissipation holes 45 formed on the transmission protective cover 44. The first pulley 41 and the second pulley 42 are connected by a transmission belt 43. In this embodiment, the transmission assembly 4 uses belt drive, resulting in lower transmission noise and improving the working environment for workers. It should be understood that the transmission assembly 4 in this embodiment can also use gear drive or chain drive depending on actual needs; the specific structure of the transmission assembly 4 is not absolutely limited here.

[0052] like Figure 7 As shown, the stirring assembly 6 will be described in detail. In this embodiment, the stirring assembly 6 includes at least one first stirring paddle 61 and at least one second stirring paddle 62 that are sequentially sleeved on the stirring shaft 5. Any adjacent first stirring paddle 61, any adjacent second stirring paddle 62, and adjacent first stirring paddle 61 and second stirring paddle 62 are all vertically arranged. The pushing direction of the first stirring paddle 61 on the material is opposite to the pushing direction of the second stirring paddle 62 on the material, and both push towards the middle position of the two.

[0053] like Figure 4 As shown, this embodiment takes two first stirring paddles 61 and two second stirring paddles 62 as examples. The first stirring paddle 61 includes a first fitting part (611) for fitting onto the stirring shaft 5, a first blade 612 and a second blade 613 fixedly disposed on the first fitting part (611), and the first blade 612 and the second blade 613 are perpendicular to the fixed end face of the first fitting part 611. The second stirring paddle 62 includes a second fitting part 621 for fitting onto the stirring shaft 5, a third blade 622 and a fourth blade 623 fixedly disposed on the second fitting part 621, and the third blade 622 and the fourth blade 623 are perpendicular to the fixed end face of the second fitting part 621.

[0054] During installation, the two first agitator paddles 61 are perpendicular to each other, and the two second agitator paddles 62 are perpendicular to each other. The adjacent first agitator paddles 61 and 62 are also perpendicular to each other. When the drive motor is started, it drives the first pulley 41 to rotate. Under the action of the transmission belt 43, it drives the second pulley 42 and the agitator shaft 5 to rotate. The rotation of the two first agitator paddles 61 pushes the material in the horizontal mixing tank 7 towards the center of the first agitator paddles 61 and 62. Simultaneously, the rotation of the two second agitator paddles 62 also pushes the material in the horizontal mixing tank 7 towards the center of the first agitator paddles 61 and 62, thus circulating, impacting, and squeezing the material towards the center. To achieve better mixing, the first stirring blade 61 and the second stirring blade 62 are installed opposite to each other. The first stirring blade 61 pushes the material in the opposite direction to the second stirring blade 62. The first stirring blade 61 and the second stirring blade 62 push the material from both sides to the middle, circulating, impacting and squeezing the material. This type of stirring component 6 does not require a high shear rate to achieve high-efficiency and high-quality mixing. The low shear rate avoids the structural damage to the active material in the powder caused by the high shear rate in the prior art. While ensuring sufficient fiberization of the powder, the structural integrity of the active material is guaranteed, and the wear rate and energy consumption of the equipment are reduced.

[0055] In this embodiment, the horizontal mixing tank 7 can be a conical or cylindrical tank. If a conical tank is used, the edges of the first stirring blade 61 and the second stirring blade 62 installed inside the conical tank should be consistent with the shape of the horizontal mixing tank 7 to ensure optimal matching between the stirring blades and the horizontal stirring blades, achieving high-quality and high-efficiency mixing. As a preferred embodiment, the horizontal mixing tank 7 in this embodiment uses a conical tank, with the left stirring diameter of the first stirring blade 61 being larger than the right stirring diameter, and the left stirring diameter of the second stirring blade 62 being smaller than the right stirring diameter.

[0056] The mixing device in this embodiment also includes a control mechanism 30 installed in the second mounting cavity 9. The control mechanism 30 is used to control the start and stop, speed and rotation direction of the drive motor. The specific structure and control principle of the control mechanism 30 will not be described in detail here. Those skilled in the art should be able to obtain it simply according to actual needs.

[0057] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
