Description
Technical Field
[0001] This utility model relates to the field of mixer technology, and in particular to a multi-directional flow structure for the impeller blades of a high-speed mixer. Background Technology
[0002] In the production of plastic filler masterbatch, high-speed mixers can fully mix the base resin with various additives, such as pigments, fillers, plasticizers, stabilizers, and lubricants. Through the intense stirring of the high-speed mixer, raw materials with different properties and particle sizes can reach a highly uniform mixing state in a short time, ensuring the consistency and stability of the plastic masterbatch performance.
[0003] In existing technologies, when a high-speed mixer is in operation, the motor of the high-speed mixer drives the stirring shaft to rotate at high speed through the drive system. The stirring blades on the stirring shaft push the plastic raw materials to make complex movements in the mixing container, thereby achieving the mixing of plastic masterbatch raw materials.
[0004] The above-mentioned and existing technologies have the following drawbacks: When using a high-speed mixer, the stirring blades can only drive the plastic masterbatch raw material to move axially when rotating, which means that the high-speed mixer needs to spend a lot of time to fully mix the plastic masterbatch evenly, resulting in low working efficiency.
[0005] Therefore, a multi-directional flow structure for the impeller blades of a high-speed mixer is proposed. Utility Model Content
[0006] The purpose of this invention is to solve the problem that when the stirring blades rotate, they can only drive the plastic masterbatch raw material to move axially, which causes the high-speed mixer to take a long time to fully mix the plastic masterbatch evenly. Therefore, a multi-directional flow structure for the blades of the high-speed mixer is proposed.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-directional flow structure for a high-speed mixer blade, comprising a mixing tank, a feed hopper fixedly connected to the upper surface of the mixing tank, a valve pipe fixedly connected to the lower surface of the mixing tank, a first mixing frame rotatably connected inside the mixing tank, a plurality of mixing blades fixedly mounted on the surface of the first mixing frame, a sealing cover fixedly mounted on the bottom of the inner wall of the mixing tank, the sealing cover rotatably connected to the first mixing frame, a plurality of second mixing frames horizontally rotatably connected inside the sealing cover, a first bevel gear fixedly mounted on the lower end of the first mixing frame, a second bevel gear fixedly mounted on one end of the second mixing frame, and the first bevel gear meshing with the second bevel gear.
[0008] The effect achieved by the above components is that, by setting up components such as the first stirring frame, stirring blades and the second stirring frame, when mixing the raw materials of plastic filler masterbatch, the first stirring frame, stirring blades and the second stirring frame work together to make the raw materials move along different trajectories and directions, thereby accelerating the mixing speed of the raw materials.
[0009] Preferably, the stirring blades are inclined to a horizontal plane.
[0010] The effect achieved by the above components is that, because the stirring blades are inclined to the horizontal plane, some of the raw materials will move upward along the surface of the stirring blades, thus making the movement of the raw materials complex.
[0011] Preferably, the surface of the stirring blade is provided with a plurality of clearance holes.
[0012] The effect achieved by the above components is that some raw materials will pass directly through the clearance holes. By setting the clearance holes, adjacent raw materials can be broken up, resulting in a better mixing effect.
[0013] Preferably, a connecting plate is fixedly mounted on the surface of the first stirring rack, and a scraper is fixedly mounted on the surface of the connecting plate, with the scraper abutting against the inner wall of the stirring tank.
[0014] The effect achieved by the above components is as follows: the rotation of the first stirring frame will drive the connecting plate to move, the movement of the connecting plate will drive the scraper to slide along the inner wall of the mixing tank, and the scraper can drive the raw materials that cannot be reached by the stirring blades to move, thereby ensuring the mixing effect.
[0015] Preferably, a screening plate is fixedly assembled on the inner wall of the feed hopper.
[0016] The effect achieved by the above components is that, by setting up a sieve plate, the sieve plate will sieve the raw materials when they are added, so as to prevent large raw materials from entering the mixing tank and affecting the mixing and subsequent normal processing.
[0017] Preferably, a perforated plate is rotatably connected to the upper surface of the screening plate, and the perforated plate abuts against the inner wall of the feed hopper.
[0018] The effect achieved by the above components is that when the perforated plate and the screening plate are misaligned, the screening plate can be blocked, thereby adjusting the screening size of the screening plate, which facilitates the screening of raw materials of different particle sizes and makes it more practical.
[0019] Preferably, an extension plate is fixedly mounted on the surface of the perforated plate, and a bolt is internally threaded onto the extension plate, the bolt passing through the extension plate and abutting against the outer wall of the feed hopper.
[0020] The effect achieved by the above components is that when the bolt passes through the extension plate and abuts against the outer wall of the feed hopper, the bolt will restrict the position of the extension plate, thereby restricting the position of the orifice plate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] 1. In this utility model, by setting components such as a first stirring frame, stirring blades and a second stirring frame, when mixing the raw materials of plastic filler masterbatch, the first stirring frame, stirring blades and the second stirring frame work together to make the raw materials move along different trajectories and directions, thereby accelerating the mixing speed of the raw materials.
[0023] 2. In this utility model, by setting a sieve plate, the sieve plate will sieve the raw materials when they are added, so as to prevent large raw materials from entering the mixing tank and affecting the mixing and subsequent normal processing. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0031] like Figures 1-4As shown, this utility model provides a multi-directional flow structure for a high-speed mixer impeller, including a mixing tank 1. A feed hopper 2 is fixedly connected to the upper surface of the mixing tank 1, and a valve pipe 3 is fixedly connected to the lower surface of the mixing tank 1. A first mixing frame 5 is rotatably connected inside the mixing tank 1. A motor 4 is fixedly connected to the upper surface of the mixing tank 1, and the output end of the motor 4 is fixedly connected to the first mixing frame 5. Several mixing blades 6 are fixedly mounted on the surface of the first mixing frame 5. A sealing cover 7 is fixedly mounted on the bottom of the inner wall of the mixing tank 1, and the sealing cover 7 is rotatably connected to the first mixing frame 5. Several second mixing frames 8 are horizontally rotatably connected inside the sealing cover 7. A first bevel gear 9 is fixedly mounted on the lower end of the first mixing frame 5, and a second bevel gear 10 is fixedly mounted on one end of each of the second mixing frames 8. The first bevel gear 9 and the second bevel gear 10 mesh with each other. By setting the first mixing frame 5, mixing blades 6, and second mixing frames 8, the raw materials of plastic filler masterbatch are... During mixing, the first stirring frame 5, stirring blade 6, and second stirring frame 8 work together to make the raw materials move along different trajectories and directions, thereby accelerating the mixing speed. The stirring blade 6 is inclined to the horizontal plane. Because the stirring blade 6 is inclined to the horizontal plane, some raw materials will move upward along the surface of the stirring blade 6, thus making the movement of the raw materials complex. Several clearance holes 11 are opened on the surface of the stirring blade 6. Some raw materials will directly pass through the clearance holes 11. By setting the clearance holes 11, adjacent raw materials can be broken up, resulting in a better mixing effect. A connecting plate 12 is fixedly mounted on the surface of the first stirring frame 5. A scraper 13 is fixedly mounted on the surface of the connecting plate 12. The scraper 13 abuts against the inner wall of the mixing tank 1. The rotation of the first stirring frame 5 will drive the connecting plate 12 to move. The movement of the connecting plate 12 will drive the scraper 13 to slide along the inner wall of the mixing tank 1. The scraper 13 can drive the raw materials that the stirring blade 6 cannot reach to move, thereby ensuring the mixing effect.
[0032] like Figures 2-4 As shown, a sieve plate 14 is fixedly installed on the inner wall of the feed hopper 2. By setting the sieve plate 14, when adding raw materials, the sieve plate 14 will sieve the raw materials to prevent large raw materials from entering the mixing tank 1 and affecting the mixing and subsequent normal processing. A perforated plate 15 is rotatably connected to the upper surface of the sieve plate 14. The perforated plate 15 abuts against the inner wall of the feed hopper 2. When the perforated plate 15 is misaligned with the sieve plate 14, it can block the sieve plate 14, thereby adjusting the sieve size of the sieve plate 14, which is convenient for sieving raw materials of different particle sizes and is more practical. An extension plate 16 is fixedly installed on the surface of the perforated plate 15. A bolt 17 is threadedly connected to the extension plate 16. The bolt 17 passes through the extension plate 16 and abuts against the outer wall of the feed hopper 2. When the bolt 17 passes through the extension plate 16 and abuts against the outer wall of the feed hopper 2, the bolt 17 will restrict the position of the extension plate 16, thereby restricting the position of the perforated plate 15.
[0033] The overall working principle is as follows: When it is necessary to mix and stir the raw material of plastic filler masterbatch, valve pipe 3 is closed and the raw material of plastic filler masterbatch is poured into feed hopper 2. The raw material will fall into mixing tank 1 through perforated plate 15 and sieve plate 14. At this time, sieve plate 14 will screen the raw material to prevent large raw materials from entering mixing tank 1 and affecting mixing and subsequent normal processing. When perforated plate 15 and sieve plate 14 are misaligned, sieve plate 14 can be blocked, thereby adjusting the screening size of sieve plate 14, which is convenient for screening raw materials of different particle sizes and is more practical. When bolt 17 passes through extension plate 16 and abuts against the outer wall of feed hopper 2, bolt 17 will restrict the position of extension plate 16, thereby restricting the position of perforated plate 15. Then, motor 4 is turned on. The output end of motor 4 will drive the first stirring frame 5 to rotate. The first stirring frame 5 will drive the stirring blade 6 to rotate. The stirring blade 6 will stir the raw material. During mixing, because the stirring blade 6 is inclined to the horizontal plane, some raw materials will move upward along the surface of the stirring blade 6, making the movement of the raw materials complex. Some raw materials will directly pass through the relief hole 11. By setting the relief hole 11, adjacent raw materials can be broken up, resulting in a better mixing effect. The rotation of the first stirring blade 6 will also drive the first bevel gear 9 to rotate, which will drive the second bevel gear 10 to rotate. The second bevel gear 10 will drive the second stirring frame 8 to rotate. The second stirring frame 8 will stir the raw materials at the bottom of the mixing tank 1, causing the raw materials to move in different directions and accelerating the mixing efficiency. The rotation of the first stirring frame 5 will drive the connecting plate 12 to move. The movement of the connecting plate 12 will drive the scraper 13 to slide along the inner wall of the mixing tank 1. The scraper 13 can drive the raw materials that the stirring blade 6 cannot reach to move, thereby ensuring the mixing effect. After mixing is completed, the valve pipe 3 is opened to discharge the raw materials through the valve pipe 3.
[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
