Description

Technical Field

[0001] This invention relates to the field of solid powder mixing and processing technology, specifically a solid powder mixing device. Background Technology

[0002] Solid powder mixing equipment is a core component in industries such as building materials, chemicals, and food, enabling the uniform mixing of multi-component powders. Currently, mainstream powder mixing equipment on the market suffers from the following structural and technological deficiencies:

[0003] Firstly, the feeding and metering mechanism is inadequate. In existing devices, most still rely on manual weighing before pouring into the feeding hopper. A few devices equipped with automatic metering equipment lack effective buffering and connection structures between their metering and mixing mechanisms. This leads to the easy segregation or leakage of metered materials during transfer, and the components cannot be fed in sequence, affecting the uniformity of mixing.

[0004] Secondly, the mixing mechanism has a simple structure and low mixing efficiency. The stirring components of existing conical mixers or horizontal mixers are mostly single-layer blade structures, which can only achieve material propulsion in one direction. This easily creates mixing dead zones, and the material cannot form a full-range convection circulation in the cylinder, resulting in prolonged mixing time and substandard mixing uniformity.

[0005] Third, the equipment lacks adequate sealing and dust control structures. The interfaces of the existing equipment (feeding port, discharge port, maintenance port) are mostly simple flange connections or directly open, lacking effective mechanical seals and negative pressure suction structures. During operation, powder can easily escape from the gaps, causing not only material loss but also serious pollution to the production environment.

[0006] To address the above problems, the present invention provides a solid powder mixing device with a compact structure, good sealing performance, and high mixing efficiency. Summary of the Invention

[0064] In this embodiment, during device operation, different powders can be quantitatively fed into the inner side of the mixing cylinder 2 according to requirements. The control component drives the stirring component, which stirs and mixes the powders located inside the mixing cylinder 2. Simultaneously, the control component can synchronously drive the transmission and control component, which can further drive the stirring component in operation, allowing the stirring component to adjust the stirring range. This enables the device to fully and thoroughly stir the powders located inside the mixing cylinder 2. By setting up a quantitative feeding component and a mixing module, this invention can not only achieve precise delivery of powders but also achieve full and thorough stirring of the powders, which not only shortens the mixing time but also ensures the uniformity of mixing.

[0065] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The stirring assembly includes a support rod, an L-shaped scraper 18, and a first stirring rod.

The first stirring rod is fixedly arranged between the L-shaped scrapers 18 and the support rod.

[0066] In this embodiment, the control component drives the support rod to rotate, and the support rod drives the first stirring rod to rotate. The first stirring rod is used to stir the powder located inside the mixing cylinder 2. The support rod can also drive the L-shaped scraper 18 to rotate synchronously. The L-shaped scraper 18 can prevent the powder from adhering to the cylinder wall, thereby improving the thoroughness of mixing.

[0071] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 The control component includes a first motor 8 fixedly mounted inside the base 1 and a drive rod 7 connected to the output end of the first motor 8. The drive rod 7 is connected to a support rod via a belt. A cam 31 is also fixedly mounted on the outside of the drive rod 7. A push plate 33 is abutted on the outside of the cam 31. The push plate 33 is slidably connected to a guide rod 32 fixedly mounted inside the base 1. A spring is fixedly mounted between the push plate 33 and the base 1. A connecting rod 9 is rotatably mounted on the push plate 33. The other end of the connecting rod 9 is rotatably connected to a lifting block 6 slidably mounted on the base 1. The lifting block 6 is rotatably connected to a turntable 10.

[0072] In this embodiment, the belt component includes a pulley fixedly disposed on the outside of the drive rod 7 and the support rod, and a belt for connecting the pulley. The first motor 8 drives the drive rod 7 to rotate. The drive rod 7 realizes the rotation of the support rod through the pulley and the belt. The drive rod 7 can also realize the rotation of the cam 31. With the help of the spring disposed between the push plate 33 and the base 1, the push plate 33 is driven to reciprocate along the guide rod 32. The push plate 33, together with the connecting rod 9, realizes the lifting of the lifting block 6, thereby completing the drive of the transmission and control component.

[0073] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The quantitative feeding assembly includes several quantitative seats 19 fixedly installed on the top wall of the mixing cylinder 2. A feeding cylinder 4 is provided on the outer side of the top of the quantitative seat 19. A conveying pipe 23 is fixedly installed between the feeding cylinder 4 and the quantitative seat 19. A solenoid valve is fixedly installed on the inner side of the bottom end of the conveying pipe 23. A second motor 21 is fixedly installed on the inner side of the feeding cylinder 4. The output end of the second motor 21 is connected to a spiral push rod 22 that leads to the inner side of the conveying pipe 23. A weighing assembly connected to the mixing cylinder 2 is provided on the outer side of the bottom end of the quantitative seat 19.

[0074] In this embodiment, the powder is stored in the feeding cylinder 4. The second motor 21 drives the spiral push rod 22 to rotate. The powder located inside the feeding cylinder 4 enters the inner side of the metering seat 19 along the conveying pipe 23. The weighing component works with the metering seat 19 to weigh the powder.

[0075] In one embodiment of the present invention, please refer to Figure 3 The weighing assembly includes a weighing platform 24, a sensor 25, and a base plate 26. The base plate 26 is located on the outer side of the bottom of the metering seat 19. A rotating rod 27 is fixedly installed on one side wall of the base plate 26. A gear 28 is fixedly installed on the outer side of the rotating rod 27. A gear seat 29 is meshed and connected to the outer side of the gear 28. An electric push rod 30 is fixedly installed between the gear seat 29 and the mixing cylinder 2. The weighing platform 24 is located on the outer side of the base plate 26 near the metering seat 19. The weighing platform 24 and the base plate 26 are connected by the sensor 25.

[0076] In this embodiment, during feeding, the base plate 26 cooperates with the metering seat 19 to complete the sealing of the metering seat 19. The powder conveyed along the conveying pipe 23 falls onto the weighing platform 24. The sensor 25 cooperates with the weighing platform 24 to complete the weighing of the powder. When the specified amount is reached, the solenoid valve located inside the conveying pipe 23 closes. After each powder is quantitatively conveyed, the electric push rod 30 drives the toothed seat 29 to move. The toothed seat 29 cooperates with the gear 28 to realize the rotation of the rotating rod 27. The rotating rod 27 drives the base plate 26 to flip. The powder located on the weighing platform 24 is sent into the inner side of the mixing cylinder 2. By setting the weighing component, the quantitative weighing of each powder can be completed at the same time, and the powder can be fed at the same time, which facilitates the synchronous stirring and mixing of each powder.

[0077] In one embodiment of the present invention, a feed pipe 20 is fixedly provided on the top wall of the feed cylinder 4, and a sealing cap is threadedly connected to the outside of the feed pipe 20. A feed pipe 5 is fixedly provided on the bottom wall of the mixing cylinder 2, and a solenoid valve is fixedly provided on the inside of the feed pipe 5.

[0078] This solid powder mixing device achieves independent, precise metering and synchronous feeding of various powders through a quantitative feeding component, avoiding material segregation. A control component driven by a first motor 8 simultaneously rotates the support rod and activates the cam mechanism, which in turn drives the transmission and control component, causing the slider 15 to reciprocate. This, in turn, causes the second stirring rod 16 and auxiliary rod 17 to swing, achieving dynamic adjustment of the stirring radius and angle, eliminating mixing dead zones. An L-shaped scraper 18 continuously scrapes the cylinder wall to prevent material adhesion. The overall structure is compact, with good sealing, high mixing efficiency, and excellent uniformity.

[0079] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
