Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a stirring equipment for detection. Background Art

[0002] The hyperboloid stirring equipment is a stirring device commonly used for water body stirring and mixing. The stirring part of the hyperboloid stirring equipment includes an impeller and stirring blades. The stirring blades have multiple curved surfaces and are arranged on the impeller. The impeller usually has an involute structure with a smooth transition on its outer peripheral surface.

[0003] The smooth transition outer peripheral surface of the impeller may not be able to generate sufficient turbulence or eddy current during the stirring process, resulting in low stirring efficiency. Especially when dealing with high-viscosity or easily caking materials, there is also a problem of uneven material handling on the impeller during the stirring process. Moreover, due to its structural limitations, most impellers need to be integrally formed, with high production difficulty.

[0004] For example, the application number is CN201922441748.6, which discloses a submersible hyperboloid mixer.

[0005] In view of this, the present utility model is particularly proposed. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a stirring equipment for detection, so as to solve the technical problems existing in the prior art, such as the design of the impeller in the stirring equipment has defects, the stirring efficiency is not high, the material handling is uneven, and most of them need to be integrally formed, with high production difficulty. The preferred technical solutions provided by the present utility model can produce many technical effects, which will be elaborated below.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions:

[0008] A stirring equipment for detection provided by the present utility model includes an impeller. The impeller includes curved panels. A plurality of the curved panels are sequentially spliced along the circumference of the impeller to jointly form a curved surface body impeller. A convex structure is formed at the connection of two adjacent curved panels.

[0013] Preferably, it further includes a motor, and the output shaft of the motor is connected to the impeller through a stirring shaft.

[0014] Preferably, the output shaft of the motor is connected to the stirring shaft through a connecting flange.

[0016] Preferably, it further includes a mounting base for mounting the motor, a third threaded hole is provided on the lower end face of the mounting base, and a second bolt passes through the third threaded hole and is connected to the bridge of the detection container.

[0017] The preferred technical solution of the present utility model can at least further produce the following technical effects:

[0018] The present utility model effectively avoids the technical problems existing in the prior art, such as the design of the impeller in the stirring equipment being defective, the stirring efficiency being low, the material handling being uneven, and most of them requiring integral molding manufacturing with high production difficulty. A stirring device for detection provided by the present utility model includes an impeller, and the impeller includes a curved panel.

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present utility model.

[0025] As Figure 1 - Figure 2 shown, a stirring device for detection provided by the present utility model includes an impeller 1. The impeller 1 includes curved panels 11. A plurality of curved panels 11 are sequentially spliced along the circumference of the impeller 1 to jointly form a curved surface impeller 1. A protrusion structure 2 is formed at the connection of two adjacent curved panels 11.

[0026] The impeller 1 is spliced by a plurality of curved panels 11. The modular design reduces the production difficulty compared with the integral forming in the prior art and is convenient for later maintenance. Moreover, a protrusion structure 2 is formed at the connection of two adjacent curved panels 11, so that more complex and intense water flow disturbances can be generated when the impeller 1 rotates, which helps to break the boundary layer during the stirring process and enhance the stirring effect. Especially when stirring high-viscosity or easily caking materials, the protrusion structure 2 can more effectively promote the dispersion and mixing of the materials and improve the stirring efficiency.

[0027] Further, the curved panel 11 is formed by rotating a curve along the y-axis, and the diameter gradually decreases from top to bottom, so that the impeller 1 forms an involute curved surface structure.

[0028] As an optional implementation manner, two adjacent curved panels 11 are connected by welding strips to form the protrusion structure 2.

[0029] Through the welding process, the welding strip is precisely placed at the joint of two adjacent curved panels 11, and through heating and pressure treatment, a firm welding connection is formed between the welding strip and the curved panel 11, improving the overall strength and stiffness of the impeller 1, and also capable of forming a firm convex structure 2 at the joint of the two curved panels 11. Among them, the shape and size of the welding strip can be set according to the usage requirements.

[0030] When the impeller 1 rotates, the convex structure 2 can change the direction and speed of the water flow, making the water flow form a more complex flow pattern around the impeller 1, which helps to break the boundary layer during the stirring process, enabling the material to be more evenly distributed in the detection container.

[0031] Especially when stirring high-viscosity or easily caking materials, since high-viscosity or easily caking materials are prone to forming lumps or caking during the stirring process, the lumps or caking will hinder the uniform mixing of the materials, while the convex structure 2 can more effectively promote the dispersion and mixing of the materials, break up the lumps or caking through water flow disturbance, and mix with the surrounding materials, thereby achieving a more uniform stirring effect.

[0032] As an optional implementation manner, the shape of the welding strip is a curved shape adapted to the joint of the curved panel 11.

[0033] With such a setting, the joint of the welding strip and the curved panel 11 can be closely fitted to the greatest extent, with a large contact area between the two, improving the firmness and stability of the connection.

[0034] As an optional implementation manner, the number of stirring blades 3 is multiple, and they are arranged at intervals and evenly along the circumferential direction of the impeller 1, and the stirring blades 3 are bent in the clockwise or counterclockwise direction.

[0035] Furthermore, the stirring blades 3 are arranged at a position of the impeller 1 close to the outer edge.

[0036] When the welding position of the stirring blade conflicts with the convex structure on the impeller, a groove is opened at the corresponding position on the convex structure for the stirring blade to pass through. The stirring blade is placed in the groove and welded and fixed to the convex structure.

[0037] During the stirring process, the bent stirring blades 3 can guide the material flow and generate a complex flow pattern, which helps to break the boundary layer of the material and enhance the stirring effect. Among them, the number, specifications, and specific bending direction of the stirring blades 3 can be set according to the usage scenario requirements.

[0038] When the impeller 1 rotates, through the synergistic action of the stirring blades 3 and the convex structure 2, the complex water flow disturbance generated can more effectively break the boundary layer of the material, promote the dispersion and mixing of the material, thereby enhancing the stirring effect.

[0039] As an optional implementation manner, the cross-section of the stirring blade 3 is a triangle with smooth transitions at the corners.

[0040] The cross-section of the stirring blade 3 is a triangular structure, which makes the stirring blade 3 have higher strength and stiffness compared to other shapes, and can maintain good stability and reliability during the stirring process.

[0041] The corners of the stirring blade 3 have smooth transitions, which can reduce the resistance of the material on the surface of the stirring blade 3 to a certain extent, enabling the material to flow more smoothly.

[0042] The stirring blade 3 with a cross-section that is a triangle with smooth transitions at the corners and is curved can generate stronger water flow disturbances and shear forces during the stirring process.

[0043] As an optional implementation manner, it further includes a motor 5, and the output shaft of the motor 5 is connected to the impeller 1 through a stirring shaft 4.

[0044] The motor 5 is the power source of the stirring device, providing power for the rotation of the impeller 1. The motor 5 is preferably a reduction motor 5.

[0045] As an optional implementation manner, the output shaft of the motor 5 is connected to the stirring shaft 4 through a connecting flange 7.

[0046] One end of the connecting flange 7 is connected to the output shaft of the motor 5, and the other end is connected to the stirring shaft 4. By adjusting the position of the connecting flange 7, the relative position between the output shaft of the motor 5 and the stirring shaft 4 can be conveniently adjusted, and then the distance between the impeller 1 and the bottom of the detection container can be adjusted to meet different stirring requirements.

[0047] As an optional implementation manner, a first threaded hole 121 is provided on the connecting end face 12 of the impeller 1, a connecting plate 41 is provided at the lower end of the stirring shaft 4, a second threaded hole is provided on the connecting plate 41, the first threaded hole 121 and the second threaded hole are arranged in one-to-one correspondence, and a first bolt 8 sequentially passes through the second threaded hole and the first threaded hole 121 to connect the stirring shaft 4 and the impeller 1.

[0048] Furthermore, the number of the first threaded holes 121 is multiple and they are sequentially arranged along the circumferential direction of the impeller 1, and the second threaded hole is arranged in one-to-one correspondence with the first threaded hole 121. The first bolt 8 can sequentially pass through the second threaded hole and the first threaded hole 121 to realize the assembly of the impeller 1 and the stirring shaft 4.

[0049] A slot 122 is provided at the center of the connecting end face 12, a plug rod is correspondingly provided on the connecting plate 41, and the plug rod and the slot 122 are in plug-in fit, which is convenient for positioning during the assembly of the impeller 1 and the stirring shaft 4.

[0050] As an optional implementation manner, it further includes a mounting base for mounting the motor 5. A third threaded hole 61 is provided on the lower end surface of the mounting base, and the second bolt passes through the third threaded hole 61 to connect with the bridge of the detection container.

[0051] The second bolt passes through the third threaded hole 61 of the mounting base and connects with the bridge of the detection container, so that the stirring device can be stably mounted on the detection container.
