Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment technology, specifically a centrifugal dispersion type material mixing device. Background Technology

[0002] The raw materials for biomass solid fuels mainly include agricultural waste such as crop straw, rice husks, corn cobs, peanut shells, camellia shells, and cottonseed husks, as well as forestry waste such as branches, bark, and sawdust. The mixing and processing of these raw materials is a crucial step in the production of biomass solid fuels.

[0003] Patent (CN221889656U) discloses a biomass fuel raw material mixing device, relating to the field of biomass fuel. The device includes a tank, with a valve pipe inserted into the lower left portion of the tank. A first motor is installed in the lower middle portion of the tank, a rotating component is installed in the upper left portion of the tank, and a discharge component is located in the upper middle portion of the tank. An observation window is provided on the outer surface of the tank. The output end of the first motor extends into the tank and is fixedly connected to a stirring rod, with stirring blades installed on the outer surface of the stirring rod. A feed hopper is installed at the upper end of the discharge component, and the lower end of the discharge component extends into the tank. This invention, by setting up a discharge component, can evenly spread the raw materials at the bottom of the tank, avoiding accumulation in one place, facilitating initial mixing of the raw materials, reducing subsequent mixing time, and improving work efficiency. The rotating component drives the discharge component to rotate, further improving work efficiency.

[0004] The biomass fuel additive mixing device in the aforementioned patent first feeds the material into the feeding pipe, and then uses the spiral blades inside the feeding pipe to transport the material to both sides inside the feeding pipe. Part of the material falls down from the first through hole, while most of the material falls down from the second through holes at both ends of the feeding pipe. The material inside the mixing container still shows a distribution of less in the middle and more at both ends, resulting in poor mixing effect. Furthermore, the motor is located inside the mixing container, making it extremely easy for the motor to be contaminated and damaged during the mixing process. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal dispersion material mixing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a centrifugal dispersion material mixing device, including a mixing cylinder, a stirring shaft vertically connected to the mixing cylinder, a plurality of support disks sleeved on the outer wall of the stirring shaft, a plurality of arc-shaped plates on the top of the support disks, the arc-shaped plates being distributed in a vortex shape, and an annular guide frame provided on the inner wall of the mixing cylinder outside the support disks, the annular guide frame having an inner diameter that is wider at the top and narrower at the bottom.

[0007] Furthermore, a feed pipe is provided on one side of the top of the mixing cylinder, a servo motor is provided at the center of the top of the mixing cylinder, the output shaft of the servo motor is fixedly connected to the top of the stirring shaft, a support frame is provided at the bottom of the mixing cylinder, and a discharge pipe is provided at the center of the bottom of the mixing cylinder.

[0008] Furthermore, the cross-section of the annular guide frame is an inverted isosceles trapezoidal structure, and the annular guide frame and the top of the support plate are on the same plane.

[0009] Furthermore, the vortex directions of the arc-shaped plates at the top of two adjacent support disks are opposite.

[0010] Furthermore, the outer wall of the stirring shaft is provided with helical blades above the support plate, and the height of the helical blades is greater than the height of the arc plate.

[0011] Furthermore, the outer wall of the stirring shaft is provided with a plurality of first spiral frames between two adjacent support discs, and the bottom of the outer wall of the stirring shaft is provided with a plurality of second spiral frames.

[0012] Furthermore, the first spiral frame is perpendicular to the stirring shaft, the second spiral frame is perpendicular to the stirring shaft, and the lengths of both the first and second spiral frames are greater than the bottom inner diameter of the annular guide frame.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model incorporates a mixing drum, a stirring shaft, a support disc, an arc-shaped plate, and an annular guide frame. Material falls onto the top of the support disc outside the stirring shaft. The arc-shaped plate segments the material at the top of the support disc. The rotation of the support disc causes the material on its top to rotate. Under centrifugal force, the material on the top of the support disc moves outwards, along the surface of the arc-shaped plate. During this outward throwing process, the material moves in a vortex-like pattern, and is then thrown onto the inner wall of the annular guide frame in a vortex-like pattern. After being thrown onto the inner wall surface of the annular guide frame, the material diffuses. The material is guided by a ring-shaped guide frame to the center of the mixing drum. The material then falls back onto the top of the support plate on the next layer, where it is gathered again. The material is then further divided by the arc-shaped plate on top of the support plate. The rotating support plate here centrifugally disperses and throws the material. This allows for repeated operations of material gathering, mixing, and dividing, centrifugal dispersion, guiding and gathering, and gathering, mixing, and dividing, which effectively improves the dispersion and mixing effect of the material, resulting in better dispersion and mixing within the mixing drum.

[0015] 2. In this utility model, the first spiral frame provides a spiral dispersing component between the two support discs, and the second spiral frame provides a spiral dispersing component at the bottom of the inner side of the mixing cylinder. The first and second spiral frames can rotate with the stirring shaft. During the downward movement of the material after being guided by the annular guide frame, the first spiral frame can perform spiral dispersing and guiding treatment on the material, making the material more evenly distributed between the two support discs. When the material moves to the bottom of the inner side of the mixing cylinder, the second spiral frame can perform spiral dispersing and guiding treatment on the material. Under the spiral dispersing and guiding treatment of the second spiral frame, the material can undergo multi-directional and multi-angle movement and contact mixing, which can effectively improve the mixing effect of the material.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-5This utility model provides a technical solution: a centrifugal dispersion material mixing device, including a mixing cylinder 1, a vertically rotatably connected stirring shaft 2 inside the mixing cylinder 1, a plurality of support disks 3 sleeved on the outer wall of the stirring shaft 2, a plurality of arc-shaped plates 4 on the top of the support disks 3, the arc-shaped plates 4 being distributed in a vortex shape, an annular guide frame 5 on the outer side of the support disks 3 on the inner wall of the mixing cylinder 1, the annular guide frame 5 having an inner diameter that is wider at the top and narrower at the bottom; a spiral blade 201 on the outer wall of the stirring shaft 2 above the support disks 3, the height of the spiral blade 201 being greater than the height of the arc-shaped plates 4; a plurality of first spiral frames 202 on the outer wall of the stirring shaft 2 between two adjacent support disks 3, and a plurality of second spiral frames 203 on the bottom of the outer wall of the stirring shaft 2.

[0025] In one embodiment, a feed pipe 101 is provided on one side of the top of the mixing cylinder 1, and a servo motor 102 is provided at the center of the top of the mixing cylinder 1. The output shaft of the servo motor 102 is fixedly connected to the top of the stirring shaft 2. A support frame 103 is provided at the bottom of the mixing cylinder 1, and a discharge pipe 104 is provided at the center of the bottom of the mixing cylinder 1. The feed pipe 101 is used to feed materials into the mixing cylinder 1, and a sealing component can be provided at the feed pipe 101 to allow dust generated during material mixing to drift outward from the feed pipe 101. The servo motor 102 drives the stirring shaft 2 to rotate, which in turn drives the support plate 3 and other components to rotate. The support frame 103 provides overhead support for the mixing cylinder 1 at the bottom. The discharge pipe 104 is used to discharge the materials inside the mixing cylinder 1 after the mixing process is completed.

[0026] In one embodiment, the cross-section of the annular guide frame 5 is an inverted isosceles trapezoidal structure, which allows the material to slide quickly down the inner wall of the annular guide frame 5, ensuring that the annular guide frame 5 guides and throws the material towards the center of the mixing cylinder 1; the annular guide frame 5 and the top of the support plate 3 are on the same plane, ensuring that all the material centrifugally thrown outward on the support plate 3 can fall onto the inner wall of the annular guide frame 5, and then the annular guide frame 5 will guide the material again.

[0027] In one embodiment, the vortex directions of the arc-shaped plates 4 on the tops of two adjacent support disks 3 are opposite, resulting in different distributions of the vortex-shaped spaces formed by the arc-shaped plates 4 on the two adjacent support disks 3. This allows the materials falling into the vortex-shaped spaces on the upper and lower sides to be segmented in different shapes. Furthermore, the materials on the upper and lower support disks 3 move in different directions of centrifugal dispersion under the obstruction of the arc-shaped plates 4, which can effectively improve the dispersion and mixing effect of the materials.

[0028] In one embodiment, the first spiral frame 202 is perpendicular to the stirring shaft 2, and the second spiral frame 203 is also perpendicular to the stirring shaft 2. This allows the first spiral frame 202 and the second spiral frame 203 to disperse and guide the material in the horizontal direction, effectively improving the dispersion and mixing effect of the material. The lengths of both the first spiral frame 202 and the second spiral frame 203 are greater than the bottom inner diameter of the annular guide frame 5, ensuring that the rotational range of the first spiral frame 202 and the second spiral frame 203 is greater than the range of the material moving downward along the annular guide frame 5. This guarantees that the first spiral frame 202 and the second spiral frame 203 can more comprehensively disperse and guide the material that has been guided by the annular guide frame 5.

[0029] The working principle of this utility model:

[0030] Refer to the instruction manual appendix Figures 1-5 This utility model is provided by setting up a mixing cylinder 1, a stirring shaft 2, a support plate 3, an arc plate 4 and an annular guide frame 5. The mixing cylinder 1 provides a mixing container for materials. The stirring shaft 2 rotates vertically at the center inside the mixing cylinder 1. The support plate 3 rotates with the stirring shaft 2. The arc plate 4 rotates with the support plate 3. The annular guide frame 5 guides the materials on the outside of the support plate 3 from the inner wall of the mixing cylinder 1.

[0031] In use, the material to be mixed is fed into the mixing drum 1. The material falls directly onto the top of the support plate 3 outside the stirring shaft 2. The arc-shaped plate 4 divides the material on top of the support plate 3. The stirring shaft 2 drives the support plate 3 to rotate, and the support plate 3 drives the material on top of it to rotate. Under the action of centrifugal force, the material on top of the support plate 3 moves outward. The arc-shaped plate 4 limits and guides the material on top of the support plate 3, causing the material to move outward along the surface of the arc-shaped plate 4. After the material separates from the support plate 3 and the arc-shaped plate 4, it is thrown outward. The arc-shaped plate 4 is designed to be distributed in a vortex shape, so that the material is thrown outward along the arc-shaped plate 4. The material moves outward in a vortex shape. First, under the limiting guidance of the arc plate 4, the material forms a vortex strip shape. Then, the material separates from the support plate 3 in the vortex strip shape and is thrown outward. The material is thrown onto the inner wall of the annular guide frame 5 in the vortex strip shape. After the material is thrown onto the inner wall surface of the annular guide frame 5, it diffuses. The material is guided by the annular guide frame 5 and guided to the inner center of the mixing cylinder 1. The material falls back onto the top of the support plate 3 of the next layer, and the material is gathered again on the top of the support plate 3. The material is then divided again by the arc plate 4 on the top of the support plate 3. The rotation of the support plate 3 here further disperses and throws the material centrifugally.

[0032] After the material enters the mixing drum 1, it is divided by the arc plate 4 at the top of the support plate 3. The support plate 3 rotates to centrifugally disperse and scatter the material. Then, the material is guided and collected by the annular guide frame 5 and falls back to the top of the next support plate 3. The above movement is repeated to realize the repeated operation of material collection and mixing followed by division, centrifugal dispersion, and guided collection and mixing. This can effectively improve the dispersion and mixing effect of the material, making the dispersion and mixing effect of the material inside the mixing drum 1 better.

[0033] Spiral blades 201 are provided on the outer wall of the stirring shaft 2 at the top of the support plate 3. The spiral blades 201 at the center of the top of the support plate 3 can perform spiral dispersion and mixing of materials, making the distribution of materials falling to the top of the support plate 3 more uniform and the dispersion and mixing effect of materials better.

[0034] The first spiral frame 202 provides a spiral dispersing component between the two support disks 3. The first spiral frame 202 can rotate with the stirring shaft 2. During the downward movement of the material after being guided by the annular guide frame 5, the first spiral frame 202 can perform spiral dispersing and guiding treatment on the material, making the material more evenly distributed between the two support disks 3. The second spiral frame 203 provides a spiral dispersing component at the bottom of the inner side of the mixing cylinder 1. The second spiral frame 203 can rotate with the stirring shaft 2. When the material moves to the bottom of the inner side of the mixing cylinder 1, the second spiral frame 203 can perform spiral dispersing and guiding treatment on the material. Under the spiral dispersing and guiding treatment of the second spiral frame 203, the material can move and contact with the mixing in multiple directions and angles, which can effectively improve the mixing effect of the material.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
