[0002] As is well known, the double cone mixer (SWMC) is a new type of high-efficiency, fine container rotation and stirring type mixing machine, mainly used for uniform mixing of various powdery and granular materials. It has a high degree of mixing and is suitable for industries such as magnetic powder, ceramics, chemical, pharmaceutical, and feed.
[0003] For example, Chinese utility model patent CN206526753U discloses a double-cone mixer, including a base, a double-cone mixing mechanism, a low-speed motor, and an electrical control mechanism. The base is a column-type support for the mixer, and the double-cone mixing mechanism is rotatably coupled in the base. The low-speed motor drives the double-cone mixing mechanism to rotate at a low speed to mix materials, and the electrical control mechanism controls the operation of the mixer. It features good mixing uniformity, high efficiency, simple equipment structure, and low cost.
[0004] However, the above-mentioned device still has the following defects: when mixing materials, especially when mixing multi-component materials such as Chinese medicine powder, due to the different densities of the components in the Chinese medicine powder, stratification between Chinese medicine powders of different densities is likely to occur during mixing, and the mixing effect of the materials needs to be further improved. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-cone mixer for preventing stratification, comprising a base, a double-cone cylinder rotatably mounted on the base, and a first drive motor providing power for the rotation of the double-cone cylinder; the double-cone cylinder includes a middle cylinder and conical shells at both ends, each conical shell having a conical distribution shell that fits into the inner wall of the conical shell, and an open conical annular cavity formed between the conical shell and the conical distribution shell, the opening of the open conical annular cavity facing the smaller diameter end of the conical shell, and multiple distribution pipes connected to the interior of the open conical annular cavity and extending toward the middle of the double-cone cylinder are mounted on the conical distribution shell, the distribution pipes being evenly distributed around the conical distribution shell circumferentially.
[0007] Preferably, the discharge ends of each pair of adjacent feed pipes are arranged radially offset in the middle cylinder.
[0008] Preferably, the outer wall of the distribution pipe is provided with multiple material distribution plates; further, the central axis of the distribution pipe forms an angle of 30-60 degrees with the material distribution plates, two opposite material distribution plates on the same distribution pipe are staggered, and the multiple material distribution plates are equidistantly distributed along the axial direction of the distribution pipe.
[0009] Preferably, the assembly further includes hollow sleeve shafts fixedly installed on both sides of the middle cylinder, a rotating shaft passing through the middle cylinder and through the two hollow sleeve shafts, and a second drive motor. The rotating shaft is rotatably installed on the base and is rotatably connected to the middle cylinder and the hollow sleeve shafts. The first drive motor provides power for the rotation of the hollow sleeve shaft, and the second drive motor provides power for the rotation of the rotating shaft. An agitator is installed on the rotating shaft, and the agitator is located inside the middle cylinder. Further, the rotating shaft and the hollow sleeve shafts are rotatably connected by bearings, and the rotating shaft and the middle cylinder are rotatably sealed by mechanical shaft seals, packing shaft seals, etc. The first drive motor provides power for the rotation of the hollow sleeve shafts through a transmission chain, and the second drive motor is preferably a reversible geared motor.

[0013] Compared with the prior art, this utility model provides an anti-stratification double cone mixer with the following beneficial effects: In this anti-stratification double cone mixer, the double cone cylinder is driven by a first drive motor, and the material rotates synchronously with the double cone cylinder. The denser material is concentrated near the inner wall of the double cone cylinder, while the less dense material is concentrated near the middle of the double cone cylinder. When the material enters the cone shell, some of the denser material that is attached to the inner wall of the double cone cylinder enters the open cone-shaped annular cavity. The denser material is then guided to the middle of the middle cylinder through various distribution pipes. This can promote the full contact and mixing of materials of different densities, further improve the mixing effect and mixing efficiency, and effectively prevent the material from stratifying.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0020] As described in the background art, when mixing materials, especially multi-component materials such as Chinese herbal powder, the different densities of the components in the Chinese herbal powder can easily lead to stratification between the powders of different densities, and the mixing effect of the materials needs to be further improved.
[0021] To solve this technical problem, this utility model provides an anti-segregation double cone mixer, which is applied to the mixing of powdery materials of different densities.
[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1
[0024] Please refer to Figure 1-3 A double-cone mixer for preventing stratification specifically includes: a base 1, a double-cone cylinder rotatably mounted on the base 1, and a first drive motor 2 providing power for the rotation of the double-cone cylinder; the double-cone cylinder includes a middle cylinder 3 and conical shells 4 at both ends, each conical shell 4 having a conical distribution shell 5 that fits into the inner wall of the conical shell 4, forming an open conical annular cavity 6 between the conical shell 4 and the conical distribution shell 5, the opening of the open conical annular cavity 6 facing the smaller diameter end of the conical shell 4, and multiple distribution pipes 7 installed on the conical distribution shell 5 that communicate with the interior of the open conical annular cavity and extend to the middle of the double-cone cylinder, the distribution pipes 7 being evenly distributed around the conical distribution shell 5; while guiding the material, the distribution pipes 7 can also agitate and disperse the material in the double-cone cylinder, promoting further mixing and contact of the material.
[0025] For details, please refer to Figure 4 The discharge ends of each pair of adjacent feed pipes 7 are arranged radially offset in the middle cylinder 3.
[0026] For details, please refer to Figure 3 or Figure 4 Multiple material distribution plates 8 are provided on the outer wall of the material distribution pipe 7; furthermore, the central axis of the material distribution pipe 7 forms an angle of 30-60 degrees with the material distribution plate 8, and the two opposite material distribution plates 8 on the same material distribution pipe 7 are staggered, and the multiple material distribution plates 8 are equidistantly distributed in the axial direction of the material distribution pipe 7.
[0027] For details, please refer to Figure 1 One of the conical shell sections 4 has a maintenance manhole cover 13 installed at its port, and the other conical shell section 4 has a switch valve 14 installed at its port; furthermore, the switch valve 14 can be a butterfly valve or a slide valve.
[0028] For details, please refer to Figure 3 The cone-shaped material distribution shell 5 is provided with a gentle slope 15, and the feed end of the material distribution pipe 7 extends from the gentle slope 15 into the open cone-shaped annular cavity 6.
[0029] Specifically, the double cone barrel, cone-shaped distribution shell 5, distribution pipe 7, rotating shaft 10 and stirring paddle 12 are all made of stainless steel.
[0030] The anti-stratification double cone mixer provided in this embodiment, because the discharge end of the distribution pipe 7 is radially dispersed inside the middle cylinder 3, can promote the dispersion of high-density materials in the open conical annular cavity 6 into the middle cylinder 3, thereby further improving the uniformity of contact between high-density and low-density materials; while the distribution plate 8 can block and disperse the materials in the double cone cylinder, promoting further mixing between materials, improving the mixing effect, and shortening the mixing time; the inside of the double cone cylinder can be inspected by opening the maintenance manhole cover 13, and the opening of the switch valve 14 can allow external materials to enter into the double cone cylinder or allow materials in the double cone cylinder to be discharged outwards; the stainless steel material has good rust resistance and can meet the mixing requirements of materials with high cleanliness requirements, such as traditional Chinese medicine. Example 2
[0031] For details regarding the anti-stratification double cone mixer provided in Example 1, please refer to... Figure 3It also includes hollow sleeve shafts 9 fixedly installed on both sides of the middle cylinder 3, a rotating shaft 10 passing through the middle cylinder 3 and through the two hollow sleeve shafts 9, and a second drive motor 11. The rotating shaft 10 is rotatably installed on the base 1 and is rotatably connected to the middle cylinder 3 and the hollow sleeve shafts 9. The first drive motor 2 provides power for the rotation of the hollow sleeve shafts 9, and the second drive motor 11 provides power for the rotation of the rotating shaft 10. An agitator 12 is installed on the rotating shaft 10 and is located inside the middle cylinder 3. Furthermore, the rotating shaft 10 and the hollow sleeve shafts 9 are rotatably connected by bearings, and the rotating shaft 10 and the middle cylinder 3 are rotatably sealed by mechanical shaft seals, packing shaft seals, etc. The first drive motor 2 provides power for the rotation of the hollow sleeve shafts 9 through a transmission chain, and the second drive motor 11 is preferably a geared motor that can rotate in both directions.
[0032] While the first drive motor 2 drives the double cone barrel to rotate, the second drive motor 11 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the stirring paddle 12 to rotate. The stirring paddle 12 stirs and mixes the material passing through the middle cylinder 3, further improving the mixing effect of the material, effectively shortening the mixing time of the material, and improving the mixing efficiency of the material.
[0033] The process of using the anti-stratification double cone mixer provided by this utility model is as follows: Open the switch valve 14 and put the Chinese medicine and other materials into the double cone cylinder. Close the switch valve 14 and drive the first drive motor 2 to rotate the double cone cylinder. The materials rotate synchronously with the double cone cylinder. The materials with high density are concentrated near the inner wall of the double cone cylinder, and the materials with low density are concentrated near the middle of the double cone cylinder. When the materials enter the cone shell part 4, some of the high-density materials that are attached to the inner wall of the double cone cylinder enter the open cone-shaped annular cavity 6. The high-density materials are introduced into the middle cylinder part 3 through the various distribution pipes 7. The second drive motor 11 drives the rotating shaft 10 to rotate. The stirring paddle 12 stirs the materials that have entered the middle cylinder part 3. When the materials re-enter the cone shell part 4, under the action of the distribution pipes 7 and the dispersing plate 8, the materials can be further mixed to achieve uniform mixing of materials with different densities.
