Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a stirring and dispersing device. Background Technology

[0002] In the field of flame-retardant coating adhesives, formulation design and formulation are crucial, with material mixing and dispersion being a particularly important step. This is especially true for powder materials that are prone to clumping and difficult to disperse, such as bio-based carbon powders and highly hydrophobic flame retardants. While dispersants, wetting agents, and other additives used in the formulation can help wet and disperse the powder, mixing and dispersion equipment remains indispensable.

[0003] Several common types of mixing and dispersing machines on the market:

[0004] 1. Propeller-type agitator disperser: Propeller-type agitators consist of three helical blades, similar to propellers on ships. They are typically used in chemical reactions requiring vigorous stirring of materials with low viscosity. They are particularly suitable for reaction systems of emulsions or suspensions containing small amounts of solids. Their rotational speed is typically 300-600 r / min.

[0005] 2. Paddle mixer / disperser: The paddle mixer is a very simple type of mixer. It is easy to manufacture and consumes low power. It is generally divided into straight-blade paddle mixers (also called "I"-shaped paddle mixers) and folding-blade paddle mixers. It is suitable for reaction systems of two low-viscosity miscible liquids and is often used for low-speed mixing, paint mixing, etc. Its rotation speed is typically 20-80 r / min.

[0006] 3. Turbine-type agitator / disperser: The turbine agitator is a suitable agitator for reaction systems requiring very vigorous mixing. Turbine agitators can be classified into: straight blade type, curved blade type, folded blade type, disc type with straight blade, disc type with curved blade, etc. Turbine agitators are typically chosen for reaction systems involving liquids with significant differences in viscosity or relative density, suspensions containing high concentrations of solid particles, and gases requiring thorough dispersion in liquids. They are commonly used in applications requiring high-speed dispersion and deagglomeration, with speeds typically ranging from 200-1000 r / min.

[0007] 4. Frame-type or anchor-type mixing and dispersing machine

[0008] Frame and anchor mixers belong to the same type of mixer; the main difference between them is their shape. When used in suspensions, the relative density difference between the solid and liquid should not be too large. Their rotation speed is typically 15-60 r / min (this type of mixer is generally used for high-viscosity applications, such as paste-like materials with little fluidity, and requires a high-power disperser because low-speed, high-viscosity materials require a motor with sufficient torque to prevent overcurrent and ensure that insufficient torque or motor power does not burn out the motor).

[0009] It can be seen that propeller-type mixers and dispersers have relatively high requirements for the materials being processed during operation, thus their applicability is relatively poor. While paddle mixers and dispersers have a simple structure, materials tend to adhere to them, resulting in poor operational stability. Turbine mixers and dispersers have complex structures and high costs. Frame or anchor mixers and dispersers have high requirements for the motor and also suffer from poor applicability. Summary of the Invention

[0010] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a compact and highly stable stirring and dispersing device.

[0011] The objective of this utility model can be achieved through the following technical solutions:

[0012] A stirring and dispersing device includes a cylindrical shell, the upper part of which has an inlet communicating with its inner cavity, and the lower part of which has an outlet communicating with its inner cavity. The device is characterized in that it further includes a stirring assembly and a dispersing assembly connected inside the shell, the stirring assembly being located at the center of the shell, and the dispersing assembly being adjacent to the inner side of the shell.

[0013] In the above-mentioned stirring and dispersing equipment, the stirring assembly includes a drive component, a transmission shaft, and a paddle. The drive component is fixed to the outside of the housing, the transmission shaft is located inside the housing, the upper end of the transmission shaft is connected to the drive component, the paddle is long and horizontally arranged, and the inner end of the paddle is fixed to one side of the transmission shaft.

[0014] In the above-mentioned stirring and dispersing equipment, the paddles include paddle one and paddle two, which are symmetrically arranged on both sides of the drive shaft one.

[0015] In the above-mentioned stirring and dispersing device, both the first paddle and the second paddle are inclined. The first paddle and the second paddle have the same inclination angle, but opposite inclination directions.

[0016] In the above-mentioned stirring and dispersing equipment, there are several blades, and the blades are arranged adjacent to each other along the axial direction of the drive shaft.

[0017] In the above-mentioned stirring and dispersing equipment, the dispersing component includes a second driving component, a second transmission shaft, and a dispersing wheel. The second driving component is fixedly connected to the upper part of the housing. The second transmission shaft is located inside the housing, with its upper end connected to the second driving component. The dispersing wheel is connected to the lower end of the second transmission shaft and is located between two adjacent blades.

[0018] In the above-mentioned stirring and dispersing device, the dispersing wheel includes a disc-shaped body, and a number of teeth are evenly distributed on the outer circumference of the body. Each tooth has a vertically folded blade at its edge.

[0019] In the above-mentioned stirring and dispersing device, the blades include upper blades and lower blades. The upper blades are located on the upper part of the body, and the lower blades are located on the lower part of the body. The upper blades and lower blades are arranged alternately adjacent to each other.

[0020] In the above-mentioned stirring and dispersing equipment, the main body, teeth, upper blade and lower blade are an integral structure.

[0021] In the above-mentioned mixing and dispersing equipment, the inlet has an openable and closable end cap, and the outlet has an openable and closable valve.

[0022] Compared with existing technologies, this mixing and dispersing equipment has a high stability because the mixing component and the dispersing component are set up independently. The mixing component is responsible for the main mixing operation of the material in the shell, while the dispersing component assists in the mixing process.

[0023] Meanwhile, although the stirring component and the dispersing component are arranged in a centralized manner, the dispersing wheel of the dispersing component is located between two adjacent blades of the stirring component. Therefore, the two do not interfere with each other, resulting in a compact structure with high practical value. Attached Figure Description

[0030] 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. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figure 1 and Figure 2 and Figure 3 As shown, the stirring and dispersing device includes a cylindrical shell 1, with an inlet 1a communicating with its inner cavity at the upper part of the shell 1 and an outlet 1b communicating with its inner cavity at the lower part of the shell 1. It also includes a stirring assembly and a dispersing assembly connected inside the shell 1. The stirring assembly is located at the center of the shell 1, and the dispersing assembly is adjacent to the inner side of the shell 1.

[0032] The material is fed into the shell 1 through inlet 1a, and the stirring and dispersing components can make the material fully mixed together.

[0033] A valve that can be opened and closed is installed at outlet 1b. The valve is closed during operation, and once the material mixing operation is completed, the valve is opened, and the mixed material can be smoothly discharged from outlet 1b.

[0034] The stirring assembly includes a drive component 2, a transmission shaft 3, and a paddle. The drive component 2 is fixed to the outside of the housing 1, the transmission shaft 3 is located inside the housing 1, the upper end of the transmission shaft 3 is connected to the drive component 2, the paddle is long and horizontally arranged, and the inner end of the paddle is fixed to the side of the transmission shaft 3.

[0035] As the drive unit 2 drives the transmission shaft 3 to rotate continuously, the paddles located on the transmission shaft 3 rotate accordingly. The rotating paddles perform corresponding mixing processing on the materials inside the housing 1.

[0036] The blades include blade 4 and blade 5, which are symmetrically arranged on both sides of the drive shaft 3.

[0037] The arrangement of blade 4 and blade 5 improves work efficiency.

[0038] Both blade 4 and blade 5 are inclined, and the inclination angles of blade 4 and blade 5 are the same, but the inclination directions are opposite.

[0039] The inclined blades 4 and 5 enable the material to move in a spiral trajectory within the shell 1, ensuring that the material is fully mixed.

[0040] The number of blades is several, and the blades are arranged adjacent to each other along the axial direction of the drive shaft 3.

[0041] The addition of multiple blades further improves its mixing efficiency.

[0042] The dispersion assembly includes a second driving component 6, a second transmission shaft 7, and a dispersion wheel. The second driving component 6 is fixedly connected to the upper part of the housing 1. The second transmission shaft 7 is located inside the housing 1, with its upper end connected to the second driving component 6. The dispersion wheel is connected to the lower end of the second transmission shaft 7 and is located between two adjacent blades.

[0043] As the driving component 6 drives the transmission shaft 7 to rotate continuously, the dispersing wheel also rotates continuously. Since the dispersing wheel is located between two adjacent blades, it can ensure that the mixing component and the dispersing component do not interfere with each other during the auxiliary mixing operation.

[0044] The dispersion wheel includes a disc-shaped body 8, with a number of teeth 9 evenly distributed around the outer periphery of the body 8, and each tooth 9 has a vertically folded blade at its edge.

[0045] The blade includes an upper blade 10 and a lower blade 11. The upper blade 11 is located on the upper part of the body 8, and the lower blade 11 is located on the lower part of the body 8. The upper blade 10 and the lower blade 11 are alternately arranged adjacent to each other.

[0046] The upper blade 10 and lower blade 11 can fully mix the material between two adjacent blades. Of course, depending on actual needs, the number of dispersing wheels can be several, with each dispersing wheel located between two adjacent blades, which can further improve the mixing effect.

[0047] The body 8, teeth 9, upper blade 10, and lower blade 11 are an integral structure.

[0048] The entire dispersion wheel is made of plastic and can be injection molded in one step using existing injection molding technology.

[0049] The inlet 1a has an openable and closable end cap 12, and the outlet 1b has an openable and closable valve.

[0050] In this embodiment, both drive component 2 and drive component 6 are servo motors.

[0051] In this mixing and dispersing equipment, the mixing component and the dispersing component are set up independently. The mixing component is responsible for the main mixing operation of the material in the shell, while the dispersing component assists in the mixing operation, ensuring that the material in the shell can be mixed stably, and its stability is relatively high.

[0052] Meanwhile, although the stirring component and the dispersing component are arranged in a centralized manner, the dispersing wheel of the dispersing component is located between two adjacent blades of the stirring component. Therefore, the two do not interfere with each other, resulting in a compact structure with high practical value.

[0053] The technical features of the above-described 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.

[0054] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
