Description

TECHNICAL FIELD

[0001] The utility model belongs to the paint technical field for rail transit, specifically a kind of fixed telescopic pneumatic mixer. BACKGROUND

[0002] In the current paint production and use, the additives and color paste in paint are usually stored in standard oil drums with threaded holes to facilitate the preservation and management of materials. The oil drums with threaded holes are relatively common in the market, have good sealing performance and convenient storage method, and can effectively reduce external pollution and material volatilization.

[0003] During paint storage, due to the nature of the paint, phenomena such as sedimentation and oil floating are likely to occur, which can cause uneven physical properties of the paint and make it difficult to achieve the desired effect in use. In order to ensure good flowability and uniformity of the paint in use, the paint usually needs to be poured out from the original container (and oil drum) and transferred to an open container for manual stirring. This process not only wastes a large amount of paint, but also consumes a lot of manpower and time. After stirring is completed, the paint can be reloaded into the paint drum for use, which increases the waste of paint. SUMMARY

[0004] The utility model aims to provide a kind of fixed telescopic pneumatic mixer to solve at least one aspect of the problems and defects raised in the above background.

[0005] A kind of fixed telescopic pneumatic mixer is provided, comprising a pneumatic mixer, a stirring rod is arranged below the pneumatic mixer, a ball bearing is rotatably connected to the stirring rod, the ball bearing is sleeved in a threaded bung, and a dispersion disc assembly is fixedly connected to the end of the stirring rod away from the threaded bung.

[0006] Further, the threaded bung is threadedly connected above the oil drum to be stirred to ensure that the pneumatic mixer remains stable during operation.

[0007] Further, the dispersion disc assembly includes a mounting column, the mounting column is detachably connected below the stirring rod, a plurality of blade assemblies are arranged on the mounting column in the circumferential direction, the blade assemblies are expanded by centrifugal force when the stirring rod rotates at high speed, and the stirring diameter is expanded. After stopping rotation, the blade assemblies are naturally recovered due to gravity, the equipment is conveniently taken out of the oil drum to be stirred, and the blade assemblies automatically contract when stopping rotation, which facilitates the smooth removal of the equipment from the threaded hole of the oil drum to be stirred.

[0008] Further, the mounting column is fixedly connected below the stirring rod by fastening bolts, which facilitates the quick replacement of the dispersion disc assembly by the operator.

[0009] Further, the blade assembly comprises a mounting seat body arranged below the mounting column, rotating shafts are rotationally connected in the mounting seat body, and stirring blades are fixedly connected on the rotating shafts. The centrifugal force received by the stirring blades is proportional to the rotating speed. The centrifugal force makes the stirring blades rotate and expand outward along the rotating shafts to form a larger stirring diameter, effectively covering the liquid in the entire container. When the pneumatic stirrer stops stirring, the centrifugal force disappears, and the stirring blades automatically rotate and droop along the rotating shafts under the action of gravity to form an extension and contraction, facilitating the smooth removal of the equipment from the threaded hole of the oil drum to be stirred.

[0010] Further, the stirring blades are T-shaped stirring blades. The T-shaped design is used to increase the resistance when the stirring blades extend into the liquid, facilitating the expansion of the stirring blades.

[0011] Further, the stirring blades are made of stainless steel material, and the specific material is 304 austenitic stainless steel. The stainless steel blades can maintain structural stability, effectively improve the stirring efficiency, are suitable for the paint field, and avoid equipment damage or pollution caused by corrosion.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] The threaded barrel plug can fix the pneumatic stirrer on the oil drum to be stirred. The stirring rod of the pneumatic stirrer can rotate in the ball bearing inside the threaded barrel plug. The dispersing disc assembly stirs the paint in the oil drum to be stirred in the rotating process. The blades of the dispersing disc assembly can extend into the standard oil drum to be stirred. The centrifugal force of the blades of the dispersing disc assembly and the buoyancy of the paint liquid to be stirred can be brought out in the rotating process of the stirring rod driven by the pneumatic stirrer. After the stirring is completed, the blades of the dispersing disc assembly are naturally contracted by gravity, and the pneumatic stirrer can be taken out from the threaded hole of the oil drum to be stirred. The stirring can be directly carried out in the original container, the waste of manpower and materials is reduced, and the volatilization of the solvent and the splashing of the materials can be effectively prevented in the stirring process.

This is to avoid the following description from becoming unnecessarily lengthy, facilitating understanding by those skilled in the art. In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0024] Please refer to Figures 1-5 As shown in the figure, the utility model embodiment, a kind of fixed telescopic pneumatic stirrer, including pneumatic stirrer 100, and the specific model of pneumatic stirrer 100 is DAM2-50F;

[0025] The pneumatic stirrer 100 is provided below with a stirring rod 1, the stirring rod 1 is rotationally connected with a ball bearing 2, the ball bearing 2 is sleeved in a threaded barrel plug 3, a dispersion disc assembly 4 is fixedly connected to an end of the stirring rod 1 away from the threaded barrel plug 3, and the pneumatic stirrer 100 is firmly installed on a threaded hole above a to-be-stirred oil drum (not shown in the figure) through the threaded barrel plug 3.

[0026] The threaded barrel plug 3 ensures that the pneumatic stirrer 100 is fixed on the threaded hole above the to-be-stirred oil drum (not shown in the figure), preventing the equipment from shaking or detaching, and after the pneumatic stirrer 100 is started, the stirring rod 1 is driven to rotate in the threaded barrel plug 3 through the ball bearing 2, ensuring that the stirring rod 1 runs stably, and during the stirring process, the dispersion disc assembly 4 connected to the bottom of the stirring rod 1 contains a plurality of retractable blades, which are expanded under the action of centrifugal force when the stirring rod 1 rotates, forming a larger stirring range. The dispersion disc assembly 4 is expanded while being supported by the buoyancy of the liquid, making the stirring more uniform and efficient. When the stirring is completed, the pneumatic stirrer 100 stops rotating, the blades in the dispersion disc assembly 4 naturally retract due to gravity, and the entire stirring rod 1 and the dispersion disc assembly 4 are taken out from the inside of the threaded hole of the to-be-stirred oil drum by rotating the threaded barrel plug 3, without the need for additional disassembly, simple and convenient, without the need to transfer the paint or other liquid materials from the original container, directly completing the stirring in the container, greatly improving the work efficiency, and directly stirring in the original container, reducing the waste of manpower and materials, and effectively preventing the volatilization of the solvent and the splashing of the materials during the stirring process.

[0027] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the threaded barrel plug 3 is threadedly connected above the to-be-stirred oil drum (not shown in the figure), the threaded barrel plug 3 is tightly engaged with the threaded opening above the oil drum through the standard thread, forming a firm fixing point, ensuring that the pneumatic stirrer 100 remains stable during operation.

[0028] In one embodiment, please refer to Figure 1 、 Figure 4 and Figure 5As shown, the dispersion disc assembly 4 comprises a mounting column 41 which is detachably connected below the stirring rod 1, and a plurality of blade assemblies 42 are arranged on the mounting column 41 in the circumferential direction. The mounting column 41 is detachably fixed below the stirring rod 1, so that the dispersion disc assembly 4 is integrated with the stirring rod 1, and it is convenient for disassembly, cleaning and maintenance. The blade assemblies 42 are expanded or contracted according to the centrifugal force and the liquid buoyancy of the paint in the oil drum to be stirred. When the stirring rod 1 rotates at high speed, the blade assemblies 42 are expanded by the centrifugal force to expand the stirring diameter. After stopping rotation, the blade assemblies 42 are naturally recovered due to gravity, which facilitates the equipment to be taken out of the oil drum to be stirred. After the stirring is completed, the blade assemblies 42 are automatically contracted when stopping rotation, which facilitates the equipment to be smoothly taken out of the threaded hole of the oil drum to be stirred.

[0029] In one embodiment, as shown in Figure 1 , Figure 4 and Figure 5 , the mounting column 41 is fixedly connected below the stirring rod 1 by fastening bolts 5, which facilitates the operator to quickly replace the dispersion disc assembly 4.

[0030] In one embodiment, as shown in Figure 1 , Figure 4 and Figure 5 , the blade assembly 42 comprises a mounting seat body 421 which is arranged below the mounting column 41, and a rotating shaft 422 is rotatably connected in the mounting seat body 421. A stirring blade 423 is fixedly connected to the rotating shaft 422. When the pneumatic stirrer 100 rotates, the stirring blade 423 rotates at high speed with the stirring rod 1 and the mounting column 41. The centrifugal force received by the stirring blade 423 is proportional to the rotation speed. The centrifugal force makes the stirring blade 423 rotate outward along the rotating shaft 422 to expand and form a larger stirring diameter, which effectively covers the entire liquid in the container. In addition, the density and fluid buoyancy of the paint and other liquids can exert an upward thrust on the blade to help the blade expand more easily or maintain a stable operating state. When the pneumatic stirrer 100 stops stirring, the centrifugal force disappears, and the stirring blade 423 automatically rotates downward along the rotating shaft 422 under the action of gravity to form an extension and contraction, which facilitates the equipment to be smoothly taken out of the threaded hole of the oil drum to be stirred.

[0031] In one embodiment, as shown in Figure 2 and Figure 4As shown, the stirring blade 423 is a T-shaped stirring blade, when the stirring blade 423 extends into the paint and starts to rotate, the horizontal part of the stirring blade 423 increases the liquid resistance, so that the reaction force of the liquid on the stirring blade 423 increases, the rotation of the vertical part of the stirring blade 423 drives the liquid to flow, further amplifies the resistance of the liquid to the horizontal blade, so as to promote the stirring blade 423 to spread faster in the centrifugal direction on the rotating shaft 422, the T-shaped design is used to increase the resistance when extending into the liquid, facilitating the spread of the stirring blade 423.

[0032] In one embodiment, referring to Figure 2 and Figure 4 As shown, the stirring blade 423 is a stirring blade made of stainless steel material, and the specific material is 304 austenitic stainless steel. The stainless steel blade can maintain structural stability, effectively improve the stirring efficiency, and is suitable for the paint field, avoiding equipment damage or pollution caused by corrosion.

[0033] The above is only an example and description of the structure of the utility model, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the present claims, which shall belong to the protection scope of the utility model.
