Description

Technical Field

[0001] This application relates to the technical field of powder mixers, and in particular to a novel diamond-shaped powder mixer. Background Technology

[0002] A V-type powder mixer is a device that mixes dry powders through the rotation of a V-shaped cylinder. It is widely used in the pharmaceutical, food, and chemical industries, and is suitable for the uniform mixing of free-flowing powders or granular materials. Its basic working principle is that the rotation of the cylinder causes the material to tumble continuously, resulting in diffusion mixing between different components. Currently, technological improvements to V-type powder mixers mainly focus on increasing loading capacity and improving mixing uniformity, while research on the low cross-mixing efficiency of materials is relatively insufficient. In existing V-type powder mixers, the material inside must undergo a complete 360° rotation to achieve one effective mixing cycle. This structural design means that the material can only undergo one substantial mixing action per rotation, shortening the effective mixing stroke and limiting mixing efficiency. Utility Model Content

[0003] In order to improve mixing efficiency, shorten mixing cycle and increase product production efficiency without reducing mixing quality, this application provides a novel diamond-shaped powder mixer.

[0004] The above-mentioned inventive objective of this application is achieved through the following technical solutions:

[0005] A novel diamond-shaped powder mixer includes a diamond-shaped mixing cylinder and symmetrically arranged support side plates. A rotating rod is horizontally inserted through the top of the support side plates. The rotating rod is rotatably connected to the support side plates and fixedly connected to the diamond-shaped mixing cylinder. A driving mechanism is fixedly connected to one end of the rotating rod, and the driving mechanism drives the diamond-shaped mixing cylinder to rotate around the extension direction of the rotating rod.

[0006] The rhomboid mixing cylinder includes an upper V-shaped mixing cylinder and a lower V-shaped mixing cylinder arranged symmetrically. The upper V-shaped mixing cylinder has a feed inlet fixedly opened at the top, and the lower V-shaped mixing cylinder has a discharge outlet fixedly opened at the bottom.

[0007] A left support arm and a right support arm are fixedly connected between the upper V-shaped mixing cylinder and the lower V-shaped mixing cylinder. The upper V-shaped mixing cylinder, the lower V-shaped mixing cylinder, the left support arm, and the right support arm are all sealed and fixed by flanges. The outer sides of the left support arm and the right support arm are fixedly connected to the rotating rod.

[0008] By adopting the above technical solution, the flange seals and fixes the upper V-shaped mixing cylinder and the lower V-shaped mixing cylinder together with the left support arm and the right support arm, respectively, forming a diamond-shaped mixing cylinder. The left and right support arms are respectively set on both sides of the diamond-shaped mixing cylinder, which serves to support the weight of the entire mixing cylinder and also acts as a transmission path for rotational power, effectively transmitting power to the mixing cylinder while ensuring its stability and balance during high-speed rotation. The drive mechanism is installed inside the support side plate on the right side of the diamond-shaped mixing cylinder to control the rotating parts other than the support side plate to achieve 360° continuous rotation. By operating the buttons on the control box, the user can easily start or stop the rotation of the mixing cylinder. The diamond-shaped structure of the mixing cylinder allows the material to be effectively mixed once every 180° rotation, which greatly shortens the mixing time, reduces the accumulation of material at the corners, improves the flowability of the material, increases the mixing speed without reducing the uniformity of the powder, reduces energy consumption costs, shortens the production cycle, and improves mixing efficiency.

[0009] Optionally, the driving mechanism includes a motor and an electrical control box, both of which are located inside the support side plate. The output end of the motor is coaxially connected to the rotating rod, and the motor drives the diamond-shaped mixing cylinder to rotate around the extension direction of the rotating rod.

[0010] By adopting the above technical solution, the user starts the motor through the electrical control box, and the rotational power generated by it is transmitted to the diamond-shaped mixing cylinder through the rotating rod, causing it to rotate around the extension direction of the rotating rod.

[0011] Optionally, the ends of the left and right support arms are respectively fixedly connected with a number of reinforcing plates, and the sidewalls of the reinforcing plates are fixedly connected to the outer wall of the rotating rod.

[0012] By adopting the above technical solution, the reinforcing plate can enhance the torsional stiffness of the support arm and mixing cylinder, especially reducing the risk of deformation under high load or high speed rotation, and extending the service life of the equipment.

[0013] Optionally, the drive mechanism further includes a reducer, and the motor is connected to the rotating rod via the reducer.

[0014] By adopting the above technical solutions, the speed reducer can accurately control the speed to adapt to the mixing requirements of different materials. For example, fragile particles require low speed, while powders require medium to high speed. This avoids excessive speed causing materials to centrifuge and stick to the wall, reducing the mixing effect, or insufficient speed causing incomplete mixing.

[0015] Optionally, the discharge port is located directly below the bottom corner of the lower V-shaped mixing cylinder and is detachably and fixedly connected with a sealing cover.

[0016] By adopting the above technical solution, the bottom corner discharge port uses gravity to discharge materials, which can reduce residues. The sealing cover can prevent powder leakage during the mixing process, which helps to improve the finished product recovery rate and ensure the airtightness of the mixing environment.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The flange seals and fixes the upper V-shaped mixing cylinder and the lower V-shaped mixing cylinder together with the left support arm and the right support arm, respectively, forming a diamond-shaped mixing cylinder. The left and right support arms are respectively set on both sides of the diamond-shaped mixing cylinder, which serves to support the weight of the entire mixing cylinder and also serves as the transmission path for rotational power, effectively transmitting power to the mixing cylinder while ensuring its stability and balance during high-speed rotation. The drive mechanism is installed inside the support side plate on the right side of the diamond-shaped mixing cylinder to control the rotating parts other than the support side plate to achieve 360° continuous rotation. By operating the buttons on the control box, the user can easily start or stop the rotation of the mixing cylinder. The diamond-shaped structure of the mixing cylinder allows the material to be effectively mixed once every 180° rotation, which greatly shortens the mixing time, reduces the accumulation of material at the corners, improves the flowability of the material, increases the mixing speed without reducing the uniformity of the powder, reduces energy consumption costs, shortens the production cycle, and improves mixing efficiency.

[0019] 2. The reinforcing plate can enhance the torsional rigidity of the support arm and mixing cylinder, especially reducing the risk of deformation under high load or high speed rotation, thus extending the service life of the equipment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Reference Figure 1-2This embodiment discloses a novel rhomboid mixing machine, including a rhomboid mixing cylinder and symmetrically arranged support side plates 1. A rotating rod 11 is horizontally inserted through the top of the support side plate 1, and the rotating rod 11 is rotatably connected to the support side plate 1. The rotating rod 11 is fixedly connected to the rhomboid mixing cylinder, and a drive mechanism is fixedly connected to one end of the rotating rod 11 to control the rotating parts other than the support side plate 1 to achieve 360° continuous rotation. The drive mechanism includes a motor 12 and an electrical control box 7, both of which are located inside the support side plate 1. The output end of the motor 12 is coaxially connected to the rotating rod 11, and the motor 12 drives the rhomboid mixing cylinder to rotate around the extension direction of the rotating rod 11. The drive mechanism also includes a reducer (not shown in the figure), and the motor 12 is connected to the rotating rod 11 through the reducer. The reducer can accurately control the speed to adapt to the mixing requirements of different materials. For example, fragile particles require low speed, while powders require medium to high speed. This avoids excessively high speed causing the material to centrifuge and stick to the wall, reducing the mixing effect, or insufficient speed causing incomplete mixing.

[0025] The rhomboid mixing cylinder includes an upper V-shaped mixing cylinder and a lower V-shaped mixing cylinder arranged symmetrically. The upper V-shaped mixing cylinder has a feed inlet 5 fixedly opened at the top, and the lower V-shaped mixing cylinder has a discharge outlet 9 fixedly opened at the bottom. The discharge outlet 9 is located directly below the bottom corner of the lower V-shaped mixing cylinder and is detachably and fixedly connected with a sealing cover. A left support arm 2 and a right support arm 6 are fixedly connected between the upper V-shaped mixing cylinder and the lower V-shaped mixing cylinder. The upper V-shaped mixing cylinder, the lower V-shaped mixing cylinder, the left support arm 2, and the right support arm 6 are all sealed and fixedly connected by a flange 3. The outer sides of the left support arm 2 and the right support arm 6 are fixedly connected to a rotating rod 11. Several reinforcing plates 10 are fixedly connected to the ends of the left support arm 2 and the right support arm 6, respectively. The sidewalls of the reinforcing plates 10 are fixedly connected to the outer wall of the rotating rod 11. The reinforcing plates 10 can enhance the torsional stiffness of the support arms and the mixing cylinder, especially reducing the risk of deformation under high load or high speed rotation. Flange 3 seals and fixes the upper V-shaped mixing cylinder and the lower V-shaped mixing cylinder together with the left support arm 2 and the right support arm 6, respectively, forming a diamond-shaped mixing cylinder. The left support arm 2 and the right support arm 6 are respectively set on both sides of the diamond-shaped mixing cylinder, which plays the role of supporting the weight of the entire mixing cylinder and also serves as the transmission path of rotational power, effectively transmitting power to the mixing cylinder, while ensuring its stability and balance during high-speed rotation. The diamond-shaped structure of the mixing cylinder allows the material to be effectively mixed once every 180° rotation, which greatly shortens the mixing time, reduces the accumulation of material at the corners, improves the flowability of the material, increases the mixing speed without reducing the uniformity of the powder, reduces energy consumption costs, shortens the production cycle, and improves the mixing efficiency.

[0026] The implementation principle of the novel diamond-shaped mixing machine of this application is as follows: When materials need to be mixed, the sealing plug at the feed inlet 5 at the top of the upper V-shaped mixing cylinder is first opened, and the materials to be mixed are poured into the diamond-shaped mixing cylinder from the feed inlet 5. Then, the feed inlet 5 is tightened by the sealing plug. Finally, the motor 12 is started so that the rotational power generated is transmitted to the diamond-shaped mixing cylinder through the rotating rod 11, causing it to rotate around the axis. When the diamond-shaped mixing cylinder rotates, the materials inside the diamond-shaped mixing cylinder will slide down along the inner wall of the cylinder under the action of gravity, and complete one cross-mixing every time it rotates 180°. When the mixing cylinder rotates to 180°, the materials slide from one end to the other end and mix with it. When it continues to rotate to 360°, the materials return to the initial position, but the second effective mixing has been completed. Therefore, in a complete 360° rotation cycle, the diamond-shaped mixing machine can achieve two efficient mixing processes. After the mixing is completed, the motor 12 is turned off, the sealing cover of the discharge port 9 is opened, and the uniformly mixed materials are discharged, completing the entire mixing process.

[0027] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
