Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of stirring paddle, concretely relates to a novel stirring paddle for material fully stirring and stirring tank. BACKGROUND

[0002] In the vacuum material preparation system, the material is fully degassed, and stirring and mixing are very important. A reasonable stirring structure can not only greatly save the material preparation time, but also promote the efficient and sufficient mixing of the material. At the same time, the reasonableness of the stirring structure is also important for energy consumption. An unreasonable stirring mechanism not only has large resistance, but also has poor service life, and increases the energy consumption of the driving motor.

[0003] For the mixing and stirring of materials, especially high-viscosity or viscous mixtures, most of the current stirring paddles adopt an anchor type structure, such as a stirring paddle for a stirring tank in CN221733170U. However, the anchor type stirring paddle has the following shortcomings:

[0004] Firstly, the anchor type stirring paddle is not conducive to the mixing of multiple materials, which greatly increases the mixing time.

[0005] Secondly, although the anchor type stirring paddle runs stably, the effect of the mixing and stirring of materials, especially high-viscosity materials, is not ideal. This is because the stirring process of the anchor type stirring paddle is a flat pushing mode, so it cannot mix the upper, middle and lower materials in the axial direction of the stirring main shaft.

[0006] Thirdly, since the stirring process of the anchor type stirring paddle is a flat pushing mode, the load of the driving motor will increase for materials with high viscosity, causing energy loss. INVENTION CONTENTS

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. It needs to be explained that the description of these embodiments is used for helping understanding the utility model, but does not constitute limitation on the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Referring to Figs. 1 to 3 As shown in FIG. 1, a novel stirring paddle for sufficient stirring of materials comprises a stirring main shaft 1, a first cross bar 2 and a second cross bar 3 arranged at intervals on the stirring main shaft 1, and a first cross member 4 and a second cross member 5 connected to the first cross bar 2 and the second cross bar 3.

[0024] When the stirring main shaft 1 is working, the first cross member 4 and the second cross member 5 rotate with the stirring main shaft 1, at which time the materials are affected by the first cross member 4 and the second cross member 5, not only rotating along the tangential direction, but also flowing along the circular cross section of the first cross member 4 and the second cross member 5. When the materials run to the highest critical point, they drop into the lower layer due to the action of gravity. With the increase of the input of materials, the overturning effect is particularly obvious, thereby promoting the sufficient stirring and fusion of the materials.

[0025] By designing the first cross member 4 and the second cross member 5 arranged in a left-right cross manner, the materials can interact along the axial and tangential directions of the stirring main shaft 1, not only reducing the resistance in the stirring process, but also not needing a very large power of the driving motor 6, and being more convenient and efficient for the mixing sufficiency of various materials.

[0026] The length of the first cross bar 2 is greater than that of the second cross bar 3. This design principle is based on the physical properties of the materials at the bottom of the stirring tank and stirring dynamics. In the stirring process, the materials located at the bottom of the tank have relatively poor fluidity due to the action of gravity, so a greater force is needed to push these materials for mixing. The first cross bar 2 is mainly responsible for preliminary stirring, which is located in the upper layer of the materials, and the fluidity of the materials here is good, so the required stirring intensity is relatively small, and the first cross bar 2 needs to have sufficient length to cover the materials in the upper layer to ensure that the materials can be fully stirred, thereby reducing the stirring dead angle and improving the stirring efficiency. Moreover, as the materials are gradually added to the stirring tank, the accumulation of materials at the bottom of the tank increases, which requires the second cross bar 3 to have a greater pushing force to push the materials, which requires the driving motor 6 to provide more power. Therefore, the length of the first cross bar 2 is designed to be longer than that of the second cross bar 3, in order to ensure that the power of the driving motor 6 can be fully utilized when the materials accumulate more, so as to maintain the efficiency and effect of stirring.

[0027] The first cross bar 2 and the second cross bar 3 are connected to the stirring main shaft 1 in parallel, and the first cross bar 2 and the second cross bar 3 are horizontally arranged. The horizontal arrangement of the first cross bar 2 and the second cross bar 3 helps the material to form a horizontal flow in the stirring tank, which is important for the uniform distribution of the material. The horizontally arranged cross bar can effectively push the material to move along the tank wall, reduce the deposition of the material at the tank bottom, and also help to reduce the stratification of the material.

[0028] The first cross 4 and the second cross 5 are both in the form of ring-shaped rod structure. The first cross 4 and the second cross 5 are in the form of ring-shaped rod structure, which can reduce the energy consumption in the stirring process and make the material flow along the path formed by the first cross 4 and the second cross 5.

[0029] The first cross bar 2 is provided with a first free end 21 and a second free end 22, and the second cross bar 3 is provided with a third free end 31 and a fourth free end 32. The first free end 21 and the third free end 31 are arranged on the same side of the stirring main shaft 1. The two ends of the first cross 4 are connected to the first free end 21 and the fourth free end 32 respectively, and the two ends of the second cross 5 are connected to the second free end 22 and the third free end 31 respectively. This cross connection mode can enhance the stability of the first cross bar 2 and the second cross bar 3.

[0030] The utility model has the following at least one advantage:

[0031] Firstly, the problem of long mixing time of the traditional anchor stirring paddle is avoided. Through the form of left-right cross paddle, the material can be staggered along the tangential and axial directions, greatly reducing the mixing time.

[0032] Secondly, the problem of large driving force of the traditional anchor stirring paddle is avoided. Since the material can be decomposed along the cross section of the left-right cross paddle, instead of full resistance operation like the anchor stirring paddle, a smaller driving motor 6 can be selected under the same working condition, reducing energy consumption.

[0033] On the other hand, the utility model provides a stirring tank, which comprises a new type of stirring paddle for fully stirring material according to any one of the above, so that the stirring tank has the corresponding advantages of the new type of stirring paddle.

[0034] In the description of the utility model, need understanding is, the term "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom" "internal", "external", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and so on indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, just for the convenience of describing the utility model and simplifying the description, and not indicate or imply the device or element indicated must have a particular orientation, construct and operate in a particular orientation, therefore can not be understood as the limitation of the utility model.

[0035] In the description of the utility model, the terms "first", "second" are only for the purpose of description, and can not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.

[0036] The above only is the preferred implementation way of the utility model, and does not limit the utility model, and the utility model can have various changes and changes for the person skilled in the art. Any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
