Description

Technical Field

[0001] The invention relates to the technical field of spherical silicon micropowder, in particular to a spherical silicon micropowder stirring device. Background Art

[0002] Spherical silica powder, a unique quartz powder material, plays an important role in many industrial fields with its unique morphology and excellent performance. Its particles are perfectly spherical and its main component is silicon dioxide. This unique structure gives it excellent fluidity, dispersibility and filling properties. In the paint and coating industries, spherical silica powder can be easily integrated into them to form a uniform and delicate mixture, greatly improving the quality and performance of the product.

[0003] During the operation of the existing spherical silica powder stirring device, especially in the initial stage of adding silica powder into the stirrer, if the stirring speed is too fast, it will generate huge centrifugal force. This force may not only cause the silica powder to splash, resulting in material waste and environmental pollution, but more importantly, it may cause some silica powder to fail to be fully mixed with the paint. These silica powder particles that are not evenly dispersed are like "islands", isolated in the paint, seriously affecting the uniformity and overall performance of the paint.

[0004] When the silica powder is completely put into the mixer, if the stirring speed is not fast enough, the mixer will not be able to provide enough shear force and turbulence effect to break up the agglomerates of silica powder. These agglomerates are like small "lumps", and the gaps and cracks between them are difficult to be filled with paint, resulting in uneven mixing.

[0005] In view of this, this application is hereby filed. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 The present invention provides a technical solution: a spherical silicon powder stirring device, comprising a stirring barrel 1, a barrel cover 2 is threadedly installed on the top of the stirring barrel 1, and a stirring speed regulating mechanism is fixedly installed on the top of the barrel cover 2; The stirring speed regulating mechanism includes a motor 5 fixedly installed on the top of the barrel cover 2, a lower limit plate 4 is fixedly installed on the driving end of the motor 5, a lower slider 13 is slidably installed on the inner wall of the lower limit plate 4, a screw 14 is threadedly connected to the inner wall of the lower slider 13, a rotating shaft 12 is fixedly installed on the top of the lower slider 13, an upper slider 11 is rotatably installed on the top of the rotating shaft 12, an upper limit plate 3 is slidably installed on the outer wall of the upper slider 11, a connecting block 7 is fixedly installed on the bottom of the upper limit plate 3 away from the lower limit plate 4, and a hollow stirring column 6 is fixedly installed on the bottom of the connecting block 7.

[0024] It should be noted that: when the screw 14 starts to rotate, the driving force is generated by the close cooperation between its thread structure and the inner wall of the lower limit plate 4, thereby driving the lower slider 13 to slide smoothly along the inner wall of the lower limit plate 4, ensuring the close contact between the lower slider 13 and the lower limit plate 4. As the lower slider 13 slides, it forms a linkage mechanism with the upper slider 11 through the rotating shaft 12. The rotating shaft 12 serves as a bridge connecting the upper and lower sliders 13, which not only ensures the relative position stability between the two, but also enables the upper slider 11 to move accordingly with the sliding of the lower slider 13, further changing the relative position between the upper limit plate 3 and the lower limit plate 4, thereby achieving precise adjustment of the stirring speed; Furthermore, in the actual mixing process, according to the properties of the material, the mixing time and the desired mixing effect, the operator can flexibly adjust the relative position between the upper and lower limit plates 4 by controlling the motor 2 30 and thereby changing the rotation direction of the screw 14. This adjustment method not only allows the mixing speed to be accurately controlled according to actual needs, but also can minimize energy consumption and material loss while ensuring the mixing effect.

[0025] See also Figure 4, including a fixed ring 26 fixedly installed on the top of the upper limit plate 3 away from the lower limit plate 4, a rotating column 23 rotatably installed on the top of the fixed ring 26, an arc-shaped connecting rod 21 fixedly installed on the outer wall of the rotating column 23, a rotating column 1 22 fixedly installed on the end of the arc-shaped connecting rod 21 away from the rotating column 23, a rotating ring 16 slidably installed on the side wall of the rotating column 12, a silicon powder barrel 8 rotatably installed on the top of the rotating ring 16, and a variable blade 24 fixedly installed on the outer wall of the rotating column 12 close to the rotating ring 16.

[0026] It should be noted that the silicon micropowder is stored in the silicon micropowder barrel 8 to ensure that it is dry, pure and ready for use at any time. When the silicon micropowder needs to be added to the mixing barrel 1, the upper slider 11 is driven to move slowly toward the silicon micropowder barrel 8 by rotating the driving screw 14. As the upper slider 11 moves, the top column 15 fixedly connected to its side wall gradually approaches and finally contacts the side wall of the arc plate 20. The contact between the outer wall of the top column 15 and the side wall of the arc plate 20 generates sufficient friction, so that the rotating ring 16 starts to rotate around its center point. The rotation of the rotating ring 16 further drives the arc connecting rod 21 connected thereto to swing, so that the variable blade 24 gradually opens, preparing for the addition of silicon micropowder. When the variable blade 24 is fully opened, the silicon micropowder can fall smoothly from the silicon micropowder barrel 8 into the mixing barrel 1 under the action of gravity. Furthermore, when the top column 15 contacts the arc plate 20 and drives the rotating ring 16 to rotate, the lower slider 13 moves to the upper position of the motor 5. This position change makes the motor 5 only drive the lower limit plate 4 to rotate when driving the stirring process, while the upper limit plate 3 remains stationary. When the silicon micropowder enters the stirring barrel 1 through the variable blade 24, the hollow stirring column 6 will not rotate due to the stationary upper limit plate 3. The silicon micropowder will not be affected by any centrifugal force during the process of entering the stirring barrel 1, thereby avoiding the splashing and waste of the silicon micropowder and ensuring that the silicon micropowder can be evenly distributed in the stirring barrel 1.

[0027] See also Figure 3 , including a slide groove 17 on the top of the upper limit plate 3, a top column 15 is slidably installed on the inner wall of the slide groove 17, a support rod 31 is fixedly installed at the bottom of the top column 15, and the end of the support rod 31 is fixedly connected to the upper slider 11.

[0028] It should be noted that the top column 15 is fixedly connected to the upper slider 11 via the support rod 31 , and the opening angle of the variable blade 24 can be changed by adjusting the position of the top column 15 in the slide slot 17 .

[0029] See also Figure 3 , including a rotating ring 16 with a curved plate 20 fixedly mounted on the side wall, a spring 19 fixedly connected to the side wall of the curved plate 20, an end of the spring 19 away from the curved plate 20 fixedly connected to a fixed column 18, and the bottom of the fixed column 18 fixedly mounted on the top of the upper limit plate 3.

[0030] It should be noted that: when the rotating ring 16 completes its rotation under the push of the top column 15 and drives the variable blade 24 to open to release the silicon powder, the screw 14 drives the lower slider 13 to move in the opposite direction, so that the top column 15 leaves the arc plate 20; Furthermore, when the variable blade 24 is opened, the spring 19 is in a compressed or stretched state, storing a certain amount of elastic potential energy. Once the contact force between the top column 15 and the arc plate 20 disappears, the spring 19 begins to release its stored energy, pushing the arc plate 20 to reset along its original motion trajectory, and the rotating ring 16 connected thereto will also be subjected to corresponding traction and begin to rotate in the opposite direction, further driving the movement of the variable blade 24, causing it to gradually change from an open state to a closed state, which not only ensures that the silicon micropowder in the mixing barrel 1 will not leak out due to the opening of the variable blade 24, but also prepares for the next delivery process.

[0031] See also Figure 5 , including a stirring blade 28 fixedly mounted on the outer wall of the bottom of the hollow stirring column 6, and a powder outlet hole 29 is opened on the outer wall of the stirring blade 28.

[0032] It should be noted that the powder outlet 29 can reduce the splashing of silicon micropowder during the feeding, so that the material enters the mixing barrel 1 more smoothly, thus avoiding material waste and environmental pollution caused by splashing.

[0033] See also Figure 5 , including a discharging pipe 9 fixedly mounted on the bottom of the outer wall of the mixing barrel 1, and a discharging cover 10 hingedly connected to the inner wall of the discharging pipe 9.

[0034] It should be noted that: when the stirring process reaches a predetermined time or the material reaches an ideal uniform state, the operator only needs to simply open the discharge cover 10 on the discharge pipe 9, and the stirred material can be discharged quickly and continuously through the pipe.

[0035] See also Figure 1 , including a motor 2 30 fixedly mounted on the side wall of the lower limit plate 4 , and a driving end of the motor 2 30 is fixedly connected to the screw rod 14 .

[0036] It should be noted that by directly installing the motor 2 30 on the side wall of the lower limit plate 4 and fixedly connecting it to the screw 14, a compact layout of the entire drive system is achieved, effectively saving the space occupied by the equipment, making the entire mixing system more flexible in layout and highly adaptable.

[0037] See also Figure 4 , including a rotating hole 27 opened on the top of the fixing ring 26, the inner wall of the rotating hole 27 is rotatably connected to the outer wall of the second rotating column 23, and a connecting hole 25 is opened at the end of the variable blade 24, and the inner wall of the connecting hole 25 is fixedly connected to the outer wall of the first rotating column 22.

[0038] It should be noted that the inner wall of the connecting hole 25 matches the outer wall of the rotating column 22. The rotating column 22 is a component connected to the variable blade 24, and its outer wall has sufficient hardness and wear resistance to withstand the friction generated by the variable blade 24 during rotation.

[0039] Working principle: When motor 1 5 is started, it drives the lower limit plate 4 to rotate, and then the upper limit plate 3 is rotated through the lower slider 13 and the upper slider 11. At this time, the hollow stirring column 6 can be rotated to stir and mix the materials in the stirring barrel 1. When the speed of the hollow stirring column 6 needs to be adjusted, start motor 2 30 to rotate the screw 14, so that the lower slider 13 slides, and the upper slider 11 is fixedly connected to the lower slider 13 through the rotating shaft 12. Therefore, when the lower slider 13 moves, the upper slider 11 will also move accordingly. This movement will change the relative position of the rotation point between the upper limit plate 3 and the lower limit plate 4, thereby changing the rotation speed of the hollow stirring column 6.

[0040] During the mixing process, when silicon micropowder needs to be added, the upper slider 11 is driven to move toward the silicon micropowder barrel 8 by driving the screw 14. At this time, the outer wall of the top column 15 will contact the side wall of the arc plate 20 and drive the rotating ring 16 to rotate. The rotation of the rotating ring 16 will cause the arc connecting rod 21 to move, and then open the variable blade 24. At this time, the silicon micropowder can smoothly enter the mixing barrel 1 through the variable blade 24. Since the lower slider 13 will move above the motor 5 during the movement, the motor 5 will only drive the lower limit plate 4 to rotate, and the upper limit plate 3 remains stationary. The silicon micropowder will not be affected by centrifugal force when entering the mixing barrel 1, thereby ensuring the smoothness of the entry. When the mixing is completed, the discharge cover 10 on the discharge pipe 9 can be opened to discharge the mixed material from the mixing barrel 1.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
