Description

Technical Field

[0001] The utility model relates to the technical field of stirring paddles, in particular to a high-performance stirring paddle device. Background Art

[0002] As the core component of stirring equipment, the stirring paddle has a wide range of applications in industrial production. Its main function is to generate a vortex effect through rotation, so that various liquids or materials are mixed evenly, thereby accelerating chemical reactions, improving material uniformity, and enhancing product quality.

[0003] In the prior art, the structure of the stirring paddle is usually arranged with multiple groups of stirring components at intervals along the axial direction of the stirring shaft. Each group of stirring components includes two rows of symmetrically arranged stirring blades extending radially along the stirring shaft. This stirring paddle structure can achieve the stirring function. However, its stirring efficiency is low, and the axial flow disturbance effect is small, resulting in poor circulating flow of the axial flow inside the stirring equipment equipped with this type of stirring paddle, long required mixing time, and low production efficiency. Summary of the Utility Model

[0004] The applicant of the present utility model aims at the above-mentioned shortcomings in the existing production technology, and provides a high-performance stirring paddle device. By setting the first paddle blade assembly, the axial flow disturbance effect of the stirring device can be improved, and the stirring efficiency is high, thereby shortening the material mixing time and improving the production efficiency.

[0005] The technical solution adopted by the present utility model is as follows:

[0006] A high-performance stirring paddle device includes a main shaft. Along the axis of the main shaft, a first mounting rod and several groups of first paddle blade assemblies are sequentially installed at intervals. The first mounting rod is orthogonally arranged with the main shaft. Screw ribbon blades are respectively installed at both ends of the first mounting rod, and the two screw ribbon blades are centrosymmetrically distributed. Along the radial direction of the main shaft, the first paddle blade assemblies are arranged between the two screw ribbon blades.

[0007] As a further improvement of the above technical solution:

[0008] The first mounting rod penetrates through the main shaft and is symmetric about the axis of the main shaft.

[0009] Several second mounting rods are installed on the main shaft. A single second mounting rod connects the second paddle blade assembly and the two screw ribbon blades at the same time.

[0010] A single second mounting rod penetrates through the main shaft and is symmetric about the axis of the main shaft.

[0011] A single group of first paddle blade assemblies includes two first blades symmetrically arranged about the center of the main shaft.

[0012] The structure of a single-piece first blade is as follows: it includes an arcuate plate, and a concave first spiral arc surface is provided on the chord side end surface of the arcuate plate. The first spiral arc surface fits with the outer circumferential surface of the main shaft, so that the corresponding arcuate plate is arranged obliquely.

[0013] In the first blade assembly, the included angle between the two arcuate plates ranges from 30° to 120°.

[0014] It further includes a second blade assembly, and the second blade assembly includes two second blades arranged symmetrically about the center of the main shaft.

[0015] The structure of a single-piece second blade is as follows: it includes an airfoil plate, and a second spiral arc surface is provided at one end of the airfoil plate. The second spiral arc surface fits with the outer circumferential surface of the main shaft, so that the corresponding airfoil plate is arranged obliquely.

[0016] In the second blade assembly, the two airfoil plates are respectively fixed to the two spiral ribbon blades.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The structure of the present utility model is compact and reasonable, and it is convenient to operate. By setting the first blade assembly, the axial turbulent flow effect on the fluid during the working process of the stirring paddle device can be enhanced, thereby improving the circulating fluidity of the axial flow inside the stirring container. The stirring efficiency is high, and the rapid mixing reaction of the materials inside the stirring container can be realized.

[0020] (1) In the present utility model, by setting the mounting rod, the connection strength between the components in the stirring paddle device can be improved, thereby improving the overall structural stability of the device.

[0021] (2) In the present utility model, by setting the first blade, the materials above the stirring container can be pressed into the bottom of the stirring container, so as to promote the uniform and rapid stirring and mixing of the materials inside the stirring container.

[0022] (3) In the present utility model, by setting the second blade, the materials below the stirring container can be stirred, thereby further improving the stirring performance of the stirring paddle device.

[0023] (4) In the present utility model, by setting the spiral ribbon blade, the flow field direction generated by it is opposite to the flow field direction generated by the first blade assembly, thereby promoting the overall flow performance of the materials inside the stirring container.

[0037] The following combines the accompanying drawings to illustrate the specific embodiments of the present utility model.

[0038] The structure and function of the present utility model are as follows:

[0039] As Figures 1-9As shown in the figure, a high-performance stirring paddle device includes a main shaft 3. Along the axial direction of the main shaft 3, a first mounting rod 1 and several groups of first paddle blade assemblies are sequentially and spacedly installed. The first mounting rod 1 is orthogonally arranged with the main shaft 3. Screw ribbon blades 4 are respectively installed at both ends of the first mounting rod 1. The two screw ribbon blades 4 are centrosymmetrically distributed. Along the radial direction of the main shaft 3, the first paddle blade assemblies are arranged between the two screw ribbon blades 4. By setting the first paddle blade assemblies, the axial turbulence effect on the fluid during the working process of the stirring paddle device can be enhanced, thereby improving the stirring efficiency and realizing the rapid mixing reaction between powder and liquid, and between liquid and liquid.

[0040] In the present utility model, the main shaft 3 is the installation main body, and the mounting rod and the paddle blade assemblies are all installed on the main shaft 3. Along the axial direction of the main shaft 3, a first mounting hole and a second mounting hole group are sequentially and spacedly provided. The second mounting hole group includes several second mounting holes that are spacedly arranged along the axial direction of the main shaft 3.

[0041] The first mounting rod 1 is installed in the first mounting hole. The first mounting rod 1 penetrates through the main shaft 3 and is symmetric about the axis of the main shaft 3.

[0042] Several second mounting rods 2 are installed on the main shaft 3. A single second mounting rod 2 connects the second paddle blade assembly and the two screw ribbon blades 4 at the same time. The second mounting rod 2 is used to support the first stirring assembly and the two screw ribbon blades 4, thereby improving the structural strength of the stirring paddle device.

[0043] A single second mounting rod 2 penetrates through the main shaft 3 and is symmetric about the axis of the main shaft 3. The second mounting rod 2 corresponds to the second mounting hole one by one. The second mounting rod 2 passes through the corresponding second mounting hole and thus penetrates through the main shaft 3.

[0044] The first mounting rod 1 and the second mounting rod 2 can both be installed on the main shaft 3 by welding. In the present utility model, by setting the mounting rods, the connection strength between the components in the stirring paddle device can be improved, thereby improving the structural stability of the whole device.

[0045] A single group of first paddle blade assemblies includes two first blades 5 that are centrosymmetrically arranged about the main shaft 3. As Figure 5 shown, from the top view or bottom view perspective, the starting end of one first blade 5 is tangent to the ending end of the other first blade 5.

[0046] In the present utility model, the flow field directions generated by the two screw ribbon blades 4 are opposite to the flow field directions generated by the two first blades 5.

[0047] As Figures 6-7As shown in the figure, the structure of a single-piece first blade 5 is as follows: It includes an arcuate plate 501. On the chord side end face of the arcuate plate 501, there is a concave first spiral arc surface 502. The first spiral arc surface 502 fits with the outer circumferential surface of the main shaft 3, so that the corresponding arcuate plate 501 is arranged obliquely. The arcuate plate 501 is in an overall arcuate shape and is a flat plate with uniform thickness. It has good flow disturbance effect and can drive the fluid to flow in a large range.

[0048] In a single set of first paddle blade assemblies, the included angle range between the two arcuate plates 501 is 30° - 120°. By changing the pitch of the first spiral arc surface 502, the included angle between the two arcuate plates 501 can be adjusted, so that the flow field intensity and range generated when the first paddle blade assembly drives the fluid to flow can be changed. The preferred value of the included angle between the two arcuate plates 501 is 90°.

[0049] It further includes a second paddle blade assembly. The second paddle blade assembly is arranged below the first paddle blade assembly. The second paddle blade assembly includes two second blades 6 arranged symmetrically about the center of the main shaft 3. The second paddle blade assembly is used to increase the fluidity of the materials at the bottom of the stirring container.

[0050] As Figures 8-9 shown in the figure, the structure of a single-piece second blade 6 is as follows: It includes an airfoil plate 601. At one end of the airfoil plate 601, there is a second spiral arc surface 602. The second spiral arc surface 602 fits with the outer circumferential surface of the main shaft 3, so that the corresponding airfoil plate 601 is arranged obliquely. The inclination angle range of the airfoil plate 601 is 0° - 90°.

[0051] In the second paddle blade assembly, the two airfoil plates 601 are respectively fixed to the two spiral ribbon blades 4. In the present utility model, the two airfoil plates 601 are arranged along the axial direction of the first mounting rod 1, so as to facilitate fixing the corresponding spiral ribbon blades 4 through the airfoil plates 601. Between the corresponding end of a single spiral ribbon blade 4 and the first mounting rod 1, and between a single spiral ribbon blade 4 and the corresponding airfoil plate 601, welding can be used for fixing.

[0052] In the present utility model, the spiral ribbon blade 4, the first spiral arc surface 502, and the second spiral arc surface 602 are all spiral.

[0053] The working process of the present utility model is as follows:

[0054] When the stirring paddle device is in use, the main shaft 3 is connected to the output shaft of an external driving device (a rotating motor is used in the present utility model) through a coupling. The stirring paddle device extends into the stirring container to stir the materials placed in the stirring container;

[0055] The external driving device drives the main shaft 3 to rotate, so as to drive the two spiral ribbon blades 4, the two first blades 5, and the two second blades 6 to rotate through the main shaft 3, thereby stirring the materials;

[0056] Through the two first blades 5, the materials above in the stirring container can be pressed into the bottom of the stirring container, so as to promote the materials inside the stirring container to be stirred and mixed evenly and quickly;

[0057] Through the two second blades 6, the materials below in the stirring container can be agitated, so as to further improve the stirring performance of the stirring paddle device;

[0058] Through the two spiral ribbon blades 4, the flow field direction generated by them is opposite to the flow field direction generated by the two first blades 5, so as to promote the overall flow performance of the materials inside the stirring container.

[0059] The above description is an explanation of the present utility model, not a limitation thereof. For the scope defined by the present utility model, refer to the claims. Any form of modification can be made within the protection scope of the present utility model.
