Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical raw material mixing technology, and in particular to a chemical raw material circulating mixing device. Background Technology
[0002] A mixer is a mechanical device that uses rotating blades to transport fluids. It is used to mix two or more different substances and accelerate heat and mass transfer processes. Mixing is one of the most important unit operations in the chemical, food, metallurgical, and related industries.
[0003] There are many types of mixers available, including single-blade mixers, twin-blade mixers, and vortex mixers. However, for high-viscosity fluid chemical raw materials (such as glues and adhesives), traditional mixing equipment often cannot effectively achieve uniform mixing of materials. Especially in the production of high-viscosity fluids such as glues, the poor flowability of the materials can easily create dead zones during mixing, resulting in incomplete mixing and affecting the performance and quality of the final product. Utility Model Content
[0004] Based on this, the present invention provides a chemical raw material circulating stirring device with simple structure and convenient use. The return pipe connects the bottom and top of the mixing tank. Through the synergistic effect of the frame-type stirring paddle and the ring-type stirring blade, three-dimensional circulating stirring inside the mixing tank 12 is realized, which greatly improves the stirring and mixing efficiency.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0017] Please see Figures 1 to 5 The present invention provides a chemical raw material circulating stirring device, which includes a mixing component 10 and a stirring component 20 installed on the mixing component 10.
[0018] The mixing assembly 10 includes a support 11, a mixing tank 12 mounted on the support 11, a tank cover 13 mounted on the top of the mixing tank 12, an electric three-way valve 14 mounted on the bottom of the mixing tank 12, and a return pipe 15 connected to one side of the top of the mixing tank 12; the top and bottom of the mixing tank 12 are connected to the electric three-way valve 14 through the return pipe 15.
[0019] In this embodiment, as Figure 1 As shown, the bucket lid 13 includes a fixed cover plate 131 connected to the top of the mixing bucket 12, and a movable cover plate 132 hinged to opposite sides of the fixed cover plate 131. In actual use, opening the movable cover plate 132 allows for convenient addition of raw materials to the interior of the mixing bucket 12.
[0020] In this embodiment, the electric three-way valve 14 includes an inlet, a first outlet, and a second outlet; wherein, the inlet is used to connect to the bottom of the mixing tank 12, the first outlet is used to connect to the return pipe 15, and the second outlet is used to connect to other equipment to output the chemical raw materials that have been mixed.
[0021] The mixing assembly 20 includes a support frame 21 mounted on the lid 13, a mixing motor 22 connected to the support frame 21, an intermediate gear 23 rotatably mounted below the support frame 21, transmission gears 24 meshing with each other on opposite sides of the intermediate gear 23, transmission shafts 25 coaxially connected to each transmission gear 24, frame-type mixing blades 26 connected to each transmission shaft 25, a support beam 27 connected to the bottom of the two transmission shafts 25, a rotating shaft 28 rotatably mounted in the middle of the support beam 27, and an annular mixing blade 29 coaxially connected to the bottom of the rotating shaft 28; the annular mixing blade 29 is located above the bottom of the mixing tank 12. Each drive shaft 25 has a support beam 27 passing through its bottom end and a drive sprocket 250 coaxially connected to it. The top of the rotating shaft 28 has two intermediate sprockets 280 arranged in an array along its axis. The intermediate sprockets 280 correspond one-to-one with the drive sprockets 250. The corresponding intermediate sprockets 280 and the drive sprockets 250 are connected by a chain (not shown) so that the two drive shafts 25 can drive the rotating shaft 28 to rotate synchronously.
[0022] In this embodiment, the two drive shafts 25 have the same direction of rotation and rotation speed; the axis of the two drive shafts 25 is parallel to the axis of the rotating shaft 28, and the axis of the two drive shafts 25 is collinear with the axis of the rotating shaft 28.
[0023] Furthermore, since the two drive shafts 25 have the same direction of rotation and speed, and drive the intermediate sprocket 280 through the same chain and drive sprocket 250, the intermediate sprocket 280 will rotate with exactly the same direction of rotation and speed; that is, the intermediate sprocket 280 and the drive sprocket 250 have the same direction of rotation and speed. The two intermediate sprockets 280 are rigidly fixed to the same shaft 28, so they rotate as a whole at the same speed, without any speed conflict, and are kinematically completely compatible. Therefore, in this embodiment, the two drive sprockets 250 have the same direction of rotation and speed, and the length and tension of the two chains are consistent, ensuring uniform torque distribution.
[0024] In this embodiment, the planes of the two frame-type stirring paddles 26 remain perpendicular to each other.
[0025] Furthermore, in this embodiment, as Figure 4 As shown, each frame-type stirring paddle 26 has multiple evenly spaced drainage holes 260 on its opposite sides. The edges of the drainage holes 260 exert shear force on the fluid, providing a pressure release channel and significantly reducing stirring torque and energy consumption. Simultaneously, the high-speed jet formed when the fluid passes through the drainage holes 260 becomes a powerful micro-mixing generator, greatly enhancing the shearing, stretching, and mixing between fluid micro-clusters. This efficiently breaks down mixing dead zones, achieving homogenization within the mixing tank 12 and improving the mixing effect.
[0026] In this embodiment, as Figure 5 As shown, the annular stirring blade 29 has multiple spokes 290 evenly spaced inside, and the plane of the spokes 290 is inclined to the horizontal plane. When the inclined spokes 290 rotate, they exert a downward pushing force on the fluid, applying a downward positive pressure to the fluid at the bottom of the mixing tank 12, thereby actively outputting the fluid outward, allowing the fluid to better return to the interior of the mixing tank 12 through the return pipe 15. Through three-dimensional reciprocating stirring, the stirring and mixing efficiency is greatly improved.
[0027] The above-mentioned chemical raw material circulating stirring device has a simple structure and is easy to use. The return pipe 15 connects the bottom and top of the mixing tank 12. Through the synergistic action of the frame-type stirring paddle 26 and the ring-type stirring blade 29, the three-dimensional circulating stirring inside the mixing tank 12 is realized, which greatly improves the stirring and mixing efficiency.
[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
