Description

Technical Field

[0001] The utility model relates to a powder material mixer, in particular to a multi-position different-paddle powder material mixer. Background Art

[0002] In the process of stirring and conveying materials, especially powders with poor fluidity or high solid content materials, caking is prone to occur, resulting in uneven stirring. The Chinese patent with application number "202310227862.7" discloses a barrel bottom scraping structure for a mixer; the scraping structure adopts a flipping cross bar set at the bottom of the stirring paddle, and a scraping portion is provided on the side of the flipping cross bar. Since the flipping cross bar is only used to rotate and scrape the powder at the bottom of the barrel horizontally, the powder can only be scraped and lifted in the vertical direction. The distance is small, and it is difficult to make the powder move violently in the barrel, so it is impossible to produce uniform mixing, resulting in poor stirring and mixing effects, and it is difficult to completely solve the problem of uneven stirring caused by powder agglomeration. Utility Model Content

[0003] The utility model aims to solve the above problems and provide a multi-position different-paddle powder mixer. The mixer adopts multiple powder circulation structures so that the powder can be stirred and mixed multiple times, and has the advantages of uniform stirring, fast speed and high efficiency.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A multi-position different-paddle powder mixer, comprising

[0006] A stirring blade group is used to break up and mix the powder;

[0007] Powder lifting device, used to drive the powder at the bottom of the barrel to move upward and disperse outward;

[0008] Material barrel, used to hold powder;

[0009] A vertical drive device is used to drive the mixing blade group and the powder lifting device to slide into or out of the material barrel;

[0010] The stirring blade group and the powder lifting device are installed on the frame, and the material barrel is arranged below the stirring blade group and the powder lifting device; when the vertical driving device drives the stirring blade group and the powder lifting device to slide into the material barrel, the stirring blade group is distributed along the circumferential direction of the powder lifting device; the powder lifting device transports the powder in the material barrel from bottom to top and disperses it around, and the lifted powder is broken up and mixed by the stirring blade group to form a plurality of circulating mixing loop structures.

[0011] As a preferred solution, the powder lifting device is arranged on a frame that coincides with the central axis of the barrel.

[0012] As a preferred solution, conical blades are evenly arranged at the lower end of the powder lifting device, and the inner bottom surface of the barrel is a conical surface matching the conical blades.

[0013] As a preferred solution, the powder lifting device includes a first rotating shaft and a spiral blade wound along the axial direction of the first rotating shaft.

[0014] As a preferred solution, the powder lifting device includes a central lifting device arranged on a frame coinciding with the central axis of the barrel, and a circumferential lifting device; the circumferential lifting device and the stirring blade group are evenly distributed along the circumferential direction of the central lifting device.

[0015] As a preferred solution, the lower end of the spiral blade of the central lifting device extends into the space between two adjacent conical blades.

[0016] As a preferred solution, a scraping portion is provided at the lower end of the stirring blade group. When the vertical driving device drives the stirring blade group to slide to the lowest position in the barrel, the scraping portion and the conical blades extend into the space formed by the conical surface of the barrel.

[0017] As a preferred solution, the stirring blade group includes at least three stirring paddles: the stirring paddle is composed of a shaft head and at least two screw rods, and the scraping part is arranged at the lower end of the screw rod.

[0018] As a preferred solution, the frame is provided with a scraper for scraping off the powder adhered to the inner wall of the barrel.

[0019] As a preferred solution, the frame is provided with a first horizontal driving device for driving the stirring blade group and the powder lifting device to rotate with the central axis of the barrel as the rotating axis, and a second horizontal driving device for driving the stirring blade group and the powder lifting device to rotate.

[0020] The implementation of this utility model has the following beneficial effects:

[0021] 1. The stirring blade group of the utility model includes a plurality of stirring paddles, and the plurality of stirring paddles are distributed along the circumferential direction of the powder lifting device, thereby forming a powder circulation mixing loop structure between the plurality of powder lifting devices and the stirring paddles. When the powder lifting device is working, the powder at the bottom of the barrel is transported from the bottom to the top; and the powder is diffused around when it reaches the liquid surface, so that the powder is broken up and mixed by the stirring blade groups distributed around, thereby generating fierce hard collisions and movements, and the powder stirred and mixed by the stirring blade groups sinks to the bottom of the barrel, and then is transported from the bottom to the top again by the powder lifting device, thereby forming a circulation mixing loop structure that continuously moves the powder at the bottom of the barrel from the bottom to the top and is broken up and moved, preventing the problem of powder precipitation at the bottom of the barrel, greatly promoting the crushing and mixing of the powder, and having the advantages of uniform stirring, fast speed and high efficiency.

[0022] 2. When the conical blades rotate, they scrape and flip up the powder at the bottom of the barrel, causing the powder to move in all directions and upward. The powder moving upward is continuously transported upward by the powder lifting device, forming the above-mentioned multiple circulation mixing loop structure; while the powder moving in all directions is transported upward along the conical surface of the barrel to the stirring blade group, so that the powder moving in two directions meets at the stirring blade group and is stirred and mixed by the stirring blade group, so that the powder at the bottom of the barrel is violently collided, and the mixing is more uniform, fast and efficient.

[0023] 3. The central lifting device of the utility model conveys the upwardly moving powder upward to form the above-mentioned multiple circulating mixing loop structures; at the same time, the circumferential lifting device conveys a part of the powder moving around upward, and then when the powder reaches the surface, it gushes upward, causing the powder to diffuse around, forming an irregular movement, making the mixing more chaotic, thereby improving the uniformity of the powder mixing.

[0024] 4. When the conical blades rotate, the powder moving around only needs to move upward a short distance along the conical surface before being scraped by the scraping part into the mixing blade group for mixing and mixing, thereby reducing the upward movement time and improving the mixing and mixing efficiency.

[0025] 5. The multiple stirring paddles and the central lifting device of the utility model form multiple circulating mixing circuit structures; at the same time, the conical blades, the scraping part and the stirring paddles form a mixing circuit structure opposite to the circulating mixing circuit structure; the mixing circuit structures in two different directions allow the powders to collide and mix with each other, thereby improving the uniformity and efficiency of the mixing.

[0026] 6. In the utility model, the powder scraped from the inner wall of the barrel is guided along the scraper between two adjacent stirring paddles; when the stirring paddle revolves, the frame drives the scraper to scrape off the powder adhered to the inner wall of the barrel; the scraped powder is dispersed and mixed by the two adjacent stirring paddles at the same time, making the stirring more uniform and efficient.

[0032] Example

[0033] Reference Figures 1 to 3The present embodiment relates to a multi-position heterogeneous paddle powder mixer, comprising a stirring blade group 1 for breaking up and mixing powder, a powder lifting device 3 for driving the powder at the bottom of a barrel 2 to move upward and disperse outward, a barrel 2 for containing the powder, and a vertical driving device (not shown in the figure) for driving the stirring blade group 1 and the powder lifting device 3 to slide into or out of the barrel 2; the stirring blade group 1 and the powder lifting device 3 are installed on a frame 4, and the barrel 2 is arranged below the stirring blade group 1 and the powder lifting device 3; when the vertical driving device drives the stirring blade group 1 and the powder lifting device 3 to slide into the barrel 2, the stirring blade group 1 is distributed along the circumferential direction of the powder lifting device 3; the powder lifting device 3 transports the powder in the barrel 2 from bottom to top and disperses it to all sides, and the lifted powder is broken up and mixed by the stirring blade group 1 to form a plurality of circulating mixing loop structures.

[0034] The stirring blade group 1 of the present structure includes a plurality of stirring paddles 12, and the plurality of stirring paddles are distributed along the circumferential direction of the powder lifting device 3, thereby forming a powder circulation mixing loop structure between the plurality of powder lifting devices 3 and the stirring paddles. When the powder lifting device 3 is working, the powder at the bottom of the barrel 2 is transported from the bottom to the top; and the powder is diffused around when it reaches the liquid surface, so that the powder is broken up and mixed by the stirring blade group 1 distributed around, thereby generating fierce hard collision and movement, and the powder stirred and mixed by the stirring blade group sinks to the bottom of the barrel 2, and then is transported from the bottom to the top again by the powder lifting device 3, thereby forming a circulation mixing loop structure that continuously moves the powder at the bottom of the barrel 2 from the bottom to the top and is broken up and moved, preventing the problem of powder precipitation at the bottom of the barrel 2, greatly promoting the crushing and mixing of the powder, and having the advantages of uniform stirring, fast speed and high efficiency.

[0035] The powder lifting device 3 is arranged on a frame 4 that coincides with the central axis of the barrel 2. When the powder lifting device 3 is working, the powder at the bottom of the barrel 2 can be evenly transported to the center, and then transported upward by the powder lifting device 3; when the powder reaches the surface, it gushes upward, so that the powder spreads around, allowing the multiple stirring paddles 12 to evenly stir and mix the powder.

[0036] The lower end of the powder lifting device 3 is evenly provided with conical blades 31, and the inner bottom surface of the barrel 2 is a conical surface 21 matching the conical blades 31. A discharge port 23 with a switch valve 22 is opened at the center of the bottom end of the barrel 2. In order to facilitate the discharge of the powder in the barrel 2 through the discharge port 23, the inner bottom surface of the barrel 2 is designed as a conical surface 21. When the conical blades 31 rotate, the conical blades 31 scrape and flip the powder at the bottom of the barrel 2, so that the powder moves in all directions and upward. The powder moving upward is continuously transported upward by the powder lifting device 3 to form the above-mentioned multiple circulation mixing loop structures; and the powder moving in all directions is transported upward along the conical surface 21 of the barrel 2 to the stirring blade group 1, so that the powder moving in two directions meets at the stirring blade group 1 and is stirred and mixed by the stirring blade group 1, so that the powder at the bottom of the barrel 2 is violently collided, and the mixing is more uniform, fast and efficient.

[0037] The powder lifting device 3 includes a first rotating shaft 31 and a spiral blade 32 wound along the axial direction of the first rotating shaft 31. When working, the first rotating shaft 31 drives the spiral blade 32 to rotate; then the spiral blade 32 transports the powder at the bottom of the barrel 2 upward. When the powder reaches the surface, it gushes upward.

[0038] The powder lifting device 3 includes a central lifting device 33 provided on a frame 4 that coincides with the central axis of the barrel 2, and a circumferential lifting device 34; the circumferential lifting device 34 and the stirring blade group 1 are evenly distributed along the circumferential direction of the central lifting device 33. The central lifting device 33 conveys the powder moving upwards upwards to form the above-mentioned multiple circulation mixing loop structures; at the same time, the circumferential lifting device 34 conveys a part of the powder moving around upwards, and then when the powder reaches the surface, it gushes upwards, so that the powder spreads around, forming an irregular movement, making the mixing more chaotic, thereby improving the uniformity of the powder mixing.

[0039] The lower end of the spiral blade 32 of the central lifting device 33 extends into the space between two adjacent conical blades 31. When the conical blade 31 rotates, the powder moving upward only needs to move a small distance to be transported upward by the spiral blade 32, thereby reducing the time of upward movement and improving the efficiency of stirring and mixing. The spiral blade 32 can be set as a plurality of spiral blades, and the lower end of each spiral blade extends into the space between two adjacent conical blades 31.

[0040] The scraping part 11 is provided at the lower end of the stirring blade group 1. When the vertical driving device drives the stirring blade group 1 to slide into the lowest position in the barrel 2, the scraping part 11 and the conical blade 31 extend into the space 22 formed by the conical surface 21 of the barrel 2. When the conical blade 31 rotates, the powder moving around only needs to move a small distance upward along the conical surface 21 to be scraped by the scraping part 11 into the stirring blade group 1 for stirring and mixing, thereby reducing the time of upward movement and improving the efficiency of stirring and mixing. The scraping part 11 and the conical blade 31 are close to each other; when the stirring blade group 1 rotates, the movement trajectory of the scraping part 11 is a conical rotating body, and the taper of the rotating body is the same as the taper of the conical surface 21 of the bottom surface of the barrel 2.

[0041] The stirring blade group 1 includes at least three stirring paddles 12: the stirring paddle 12 is composed of a shaft head 121 and at least two screw rods 122, and the scraping part 11 is arranged at the lower end of the screw rod 122. The multiple stirring paddles 12 and the central lifting device 33 form multiple circulating mixing circuit structures; at the same time, the conical blades 31, the scraping part 11, and the stirring paddles 12 form a mixing circuit structure opposite to the circulating mixing circuit structure; the mixing circuit structures in two different directions make the powders collide and mix with each other, thereby improving the uniformity and efficiency of mixing.

[0042] The frame 4 is provided with a first horizontal driving device for driving the stirring blade group 1 and the powder lifting device 3 to rotate with the central axis of the barrel 2 as the rotating axis, and a second horizontal driving device for driving the stirring blade group 1 and the powder lifting device 3 to rotate. The first horizontal driving device drives the stirring blade group 1 and the powder lifting device 3 to revolve with the central axis of the barrel 2 as the central axis, while the second driving device causes the stirring blade group 1 and the powder lifting device 3 to rotate. This structure continuously lifts, flips up and breaks up the material in the barrel through the rotation and revolution of the stirring blade group 1 and the powder lifting device 3, causing the material to move irregularly and violently, thereby more efficiently mixing the powder evenly.

[0043] The frame 4 is provided with a scraper 5 for scraping off the powder adhered to the inner wall of the barrel 2. The scraper 5 is provided on the frame 4 between two adjacent stirring paddles 12, so that a scraper 5 is provided between each pair of adjacent stirring paddles 12. The scraper 5 is arranged obliquely, and the tail end of the scraper 5 is directly opposite to the space between the two adjacent stirring paddles 12; the powder scraped from the inner wall of the barrel 2 is introduced into the space between the two adjacent stirring paddles 12 along the scraper 5; when the stirring paddles 12 revolve, the frame 4 drives the scraper 5 to scrape off the powder adhered to the inner wall of the barrel 2; the scraped powder is simultaneously dispersed and mixed by the two adjacent stirring paddles 12, so that the stirring is more uniform and efficient.

[0044] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
