Description

Technical Field

[0001] This utility model relates to a low-viscosity liquid phase blowing and stirring device, belonging to the field of material stirring technology. Background Technology

[0002] In industrial production, material mixing and dispersion are common processes, and the degree of dispersion directly affects product quality. Choosing the right mixing and dispersion method for materials of different phases can achieve different dispersion effects. Common mechanical stirring devices (such as agitators) may, in some cases, result in uneven mixing, especially in large or complex-shaped containers. Air blowing agitation, on the other hand, mixes materials by blowing gas into the liquid, causing it to move. This results in more uniform mixing, reducing the presence of dead zones, and is particularly effective for dispersing materials in low-viscosity liquid phases.

[0003] However, blowing agitation also has some drawbacks. For example, during the blowing agitation process, the liquid surface is often atomized due to the rolling and breaking of bubbles, causing the liquid to float on the surface in a mist form. As the gas overflows from the top of the container, the material spreads to the surrounding area, which can cause some pollution to the working environment and even endanger the health and safety of the experimental personnel. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems with air blowing and stirring by disclosing a low-viscosity liquid phase air blowing and stirring device.

[0005] The technical solution of this utility model is as follows: a low-viscosity liquid phase blowing and stirring device, including an outer barrel, an inner barrel, an exhaust mesh plate, a rubber gasket, a switch and a base.

[0006] The base is a frustum-shaped structure with a hollow interior and multiple circular holes on the surface. A first switch and a second switch are installed on the outer surface of the base.

[0007] The base platform is covered with an exhaust mesh plate, and rubber gaskets are fixed to the edge of the exhaust mesh plate. The outer barrel is vertically installed on the rubber gasket, and the diameter of the outer barrel is the same as the diameter of the exhaust mesh plate. The inner barrel is vertically installed in the middle of the exhaust mesh plate, and the outer barrel is fitted over the inner barrel, with the outer barrel wall being higher than the inner barrel. The exhaust mesh plate is divided into an inner ring and an outer ring. The area included by the inner barrel wall on the exhaust mesh plate is the inner ring, and the area between the inner barrel wall and the outer barrel wall on the exhaust mesh plate is the outer ring. Both the inner and outer rings are provided with air holes, which correspond to the reserved holes on the base platform. The air holes in the inner ring of the exhaust mesh plate provide positive pressure blowing air, and the air holes in the outer ring of the exhaust mesh plate provide negative pressure suction air. Blowing air is controlled by a first switch, and suction air is controlled by a second switch.

[0008] Both the outer and inner barrels are cylindrical structures with through holes at both ends and no caps or bottoms. The inner barrel is welded and fixed to the exhaust mesh plate, while the outer barrel is movable, which facilitates the filling of the inner barrel. During operation, the outer barrel is simply placed on the sealing gasket and fixed by gravity.

[0009] The inner ring air holes of the exhaust mesh plate are connected to the first switch through a pipe, and the outer ring air holes of the exhaust mesh plate are connected to the second switch through a pipe.

[0010] The mixing device adopts a flow-type structure for feeding and discharging, including a pump and a pipeline; during feeding, the material is added to the inner tank through a metering pump and a hose, and then removed after feeding; after mixing is completed, the material is sucked away from the inner tank by a pump and a hose.

[0011] The outer barrel, inner barrel, and exhaust mesh are all made of transparent PVC material.

[0012] The outer barrel is equipped with handles on both sides of its cross-sectional diameter, allowing the outer barrel to be moved.

[0013] The working principle of this utility model device is as follows: The material in the inner barrel of the device is stirred by air blowing. The air source is the inner ring of the exhaust mesh plate. However, the air blowing process will generate a large amount of water vapor. In order to create a good experimental environment and prevent the water vapor from spreading, a negative pressure is formed between the inner barrel and the outer barrel through the air suction device during the air blowing process, so that the dispersed water vapor is absorbed by the exhaust mesh plate between the inner barrel and the outer barrel. Before air blowing, the air suction switch (second switch) is turned on first, then the material is added to the inner barrel, and then the air blowing switch (first switch) is turned on. The mist generated during the air blowing process is absorbed along the outer ring due to the negative pressure suction, preventing overflow.

[0014] The beneficial effects of this invention are as follows: the air-blowing agitator uses an outer barrel surrounding an inner barrel, with a negative pressure suction system set in the area between the two barrel walls. This prevents the mist generated in the inner barrel from easily diffusing outwards under negative pressure. The inner and outer barrels are fixed in different ways: the inner barrel is welded to the exhaust mesh plate, while the outer barrel is movable, facilitating material addition to the inner barrel. During operation, simply place the barrel on the sealing gasket. This air-blowing agitator is suitable for agitating low-viscosity liquid materials. Attached Figure Description

[0017] like Figure 1 As shown, this embodiment of a low-viscosity liquid phase blowing and stirring device includes an outer barrel 1, an inner barrel 3, an exhaust mesh plate 4, a rubber gasket 5, a switch, and a base 8. The outer barrel, inner barrel, and exhaust mesh plate are all made of transparent PVC material. The switch includes a first switch 6 and a second switch 7. The first switch 6 is used to control air intake; the second switch 7 is used to control air blowing.

[0018] In this embodiment, the inner barrel has a diameter of 20cm, and the outer barrel has the same diameter as the exhaust mesh plate, which is 25cm. The outer barrel wall is 10cm higher than the inner barrel, and the height of the inner barrel depends on the material. The outer barrel 1 is equipped with a handle 2, which allows the outer barrel to be moved.

[0019] In this embodiment, the base 8 is a frustum-shaped structure with a hollow interior and multiple circular holes vertically opened on the surface. The positions of the circular holes match the air intake pipe holes and air blowing pipe holes on the exhaust mesh plate. A first switch 6 and a second switch 7 are installed on the outer side of the base 5.

[0020] In this embodiment, the exhaust mesh plate 4 is laid on the base 8, and the holes on the exhaust mesh plate 4 correspond to the holes on the base 8; rubber gaskets 5 are installed on the edge of the exhaust mesh plate; the inner barrel 3 is vertically welded to the middle of the exhaust mesh plate 4, and the outer barrel 1 is fitted over the inner barrel 3 and placed on the rubber gaskets 5.

[0021] like Figure 2 As shown, the exhaust mesh plate 4 has an inner ring and an outer ring. The area included by the inner barrel wall on the exhaust mesh plate 4 is the inner ring, and the area between the inner barrel wall and the outer barrel wall on the exhaust mesh plate is the outer ring. Both the inner and outer rings are provided with air holes, which correspond to the reserved circular holes on the base platform. The air holes in the inner ring of the exhaust mesh plate provide positive pressure blowing air, and the air holes in the outer ring of the exhaust mesh plate provide negative pressure suction air. Blowing air is controlled by the first switch 6, and suction air is controlled by the second switch 7.

[0022] In this embodiment, the feeding and discharging of the mixing device adopts a flow-type structure, including a pump and a pipe. During feeding, the material is added to the inner barrel 3 through a metering pump and a hose, and then removed after feeding. After mixing is completed, the material is sucked away from the inner barrel 3 by the pump and hose.

[0023] In this embodiment, when the stirring device is working, before blowing and stirring, the suction switch (second switch 7) is turned on first, then the material is added to the inner barrel, and then the blowing switch (first switch 6) is turned on. The mist generated during the blowing process is absorbed along the outer ring due to the negative pressure suction, preventing overflow.
