Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stirring paddle structure, and particularly relates to a mixed stirring paddle structure and a beater. BACKGROUND

[0002] In the field of food processing, catering production and related industrial production, the beater is widely used in the process of batter mixing and sauce preparation as a key equipment for realizing raw material mixing and homogenization. The core function of the beater is to mix flour, water and other auxiliary materials through the rotating movement of the stirring paddle to form a batter with uniform texture and no particulate impurities, so as to ensure the taste, quality and processing stability of the subsequent products. However, the mainstream beaters on the market have the technical defect of insufficient batter mixing uniformity in the actual application process, which becomes a key bottleneck restricting the improvement of processing efficiency and product quality. Specifically, the stirring structure of the existing beater adopts a single-layer three-piece paddle design. The paddle size of this structure is small and the height is low. In the process of high-speed rotation, the circulating stirring force formed by the paddle is significantly insufficient. From the perspective of fluid mechanics, when the single-layer small-size paddle rotates, it can only drive the movement of the batter in the local area around the paddle, and cannot form a large-scale and high-intensity fluid vortex in the beater barrel. Due to the weak vortex intensity and limited coverage, the flour particles and water are difficult to achieve sufficient contact and collision in the mixing process. On the one hand, part of the flour particles are prone to float on the surface of the batter or settle at the bottom of the barrel, and cannot be effectively involved in the stirring flow field. On the other hand, even if part of the flour particles contact with the water, the mixing is not timely due to the insufficient stirring force, and a large number of flour lumps wrapped with small air bubbles are formed. The existence of these flour lumps not only seriously affects the fineness and taste of the final product (such as cakes, noodles, sauces, etc.), but also may block the feed inlet of the subsequent processing equipment, increasing the equipment maintenance cost and the risk of production interruption. To solve the problem of uneven mixing of the batter, relevant technical personnel have tried to increase the stirring motor speed to enhance the stirring effect, but this will greatly increase the energy consumption and operating noise of the equipment, and may cause the air content in the batter to exceed the standard due to excessive local shear force, further damaging the physical properties of the batter. Another solution attempts to adjust the installation angle of the paddle, but due to the single-layer three-piece basic structure, the improvement effect on the circulating stirring force is minimal, and the technical problems of insufficient mixing of flour and water and easy production of flour lumps cannot be fundamentally solved. In addition, some paddle structures are provided with double-layer stirring blades, but the principle is still to contact the paddle with the mixture and stir by high-speed rotation. The mixture far from the blade is not easy to be stirred uniformly. SUMMARY

[0021] It should be noted that the following detailed description is exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0022] Example One In one exemplary embodiment of the application, referring to Figures 1-4 Figure 1, a mixed stirring paddle structure includes a support plate 1 and a U-shaped rod group, the support plate 1 is connected to the U-shaped rod group at the top and bottom, the U-shaped rod group is buckled on the top and bottom of the support plate 1 to form a frame paddle structure, the support plate is used for fixed connection with a driving shaft, the driving shaft drives the support plate to rotate, thereby driving the frame paddle structure to rotate, realizing the stirring of the mixture composed of flour and water.

[0023] The vertical rod of the U-shaped rod group is provided with a blade 3, which is a rectangular sheet structure. In other examples, the blade can be an arc-shaped sheet structure. The vertical rod is close to the edge of the support plate, the outer side of the blade is connected with the vertical rod, and the inner side is close to the center of the support plate. The frame paddle structure is rotated, so that the mixture forms a vortex and is collected inside the frame structure and is impacted and stirred by the blade.

[0024] As shown in Figures 1-3 , the support plate 1 is a circular plate structure, the bottom center of the support plate is provided with a clamping groove for clamping with the end of the output shaft, the clamping groove 11 is a square clamping groove for clamping with the end of the output shaft of the beater, and the end of the output shaft of the beater is a square clamping block which can be clamped into the clamping groove 11. The top center of the support plate 1 is provided with a cylindrical connecting sleeve, the connecting sleeve 4 is axially provided with a through hole, the through hole is communicated with the top center position of the clamping groove 11, and the fixing member passes through the through hole and is screwed with the end of the output shaft to realize fixation. Specifically, the fixing member 5 is a bolt, which is screwed with the clamping block after passing through the through hole. By rotating the output shaft, the paddle structure can be driven to rotate, and the bolt prevents the paddle structure from being axially separated from the output shaft.

[0025] As shown in Figure 1 , the U-shaped rod group includes a first U-shaped rod 21, a second U-shaped rod 22 and a third U-shaped rod 23, wherein the first U-shaped rod 21 and the second U-shaped rod 22 are vertically buckled on the top surface of the support plate, and two groups of third U-shaped rods are vertically buckled on the bottom surface of the support plate.

[0026] The first U-shaped rod 21 and the second U-shaped rod 22 are vertically arranged, and each of the first U-shaped rod 21 and the second U-shaped rod 22 includes a horizontal rod and a vertical rod, and the horizontal rod of the first U-shaped rod 21 is higher than that of the second U-shaped rod 22. The first U-shaped rod 21 and the second U-shaped rod 22 do not contact, and in some examples, the horizontal rod of the first U-shaped rod 21 can be welded with the horizontal rod of the second U-shaped rod 22 at the center position of the bottom surface of the horizontal rod of the first U-shaped rod 21 and the center position of the top surface of the horizontal rod of the second U-shaped rod 22.

[0027] As shown in Figure 1 , the first U-shaped rod 21 and the second U-shaped rod 22 constitute an upper layer frame, both of which are provided with two vertical rods, a total of four vertical rods, and each vertical rod is provided with a group of blades 3, so that the blades are spaced 90°. The outer side of the blade is connected with the vertical rod, and the inner side is close to the center of the support plate. The adjacent blades on the vertical rods of the first U-shaped rod 21 and the second U-shaped rod 22 are staggered, and the relative blade height is the same, so as to increase the stirring area of the blade and improve the stirring effect.

[0028] As shown in Figure 4 , the adjacent blades 3 are vertically arranged, so that the plane where each blade 3 is located is relatively inclined to the plane where the U-shaped rod group of the upper layer is located. When stirring, the large surface of a group of blades of the upper layer is in contact with the mixture, and the inner side of the next group of blades is in contact with the mixture, and so on, which ensures the stirring effect.

[0029] As shown in Figure 2 , the two groups of third U-shaped rods 23 of the lower layer are arranged in parallel, and the lower ends of the two groups of third U-shaped rods 23 are connected by a connecting rod 6 to form a lower layer frame. The upper layer frame and the lower layer frame together constitute a frame paddle structure, and each group of blades is arranged on the opposite vertical rods of the two groups of third U-shaped rods, with an interval of 180°. The two lower layer blades are arranged in parallel with each other.

[0030] In an alternative example, the vertical rod of the third U-shaped rod 23 is in the same plane as the blade on the third U-shaped rod 23.

[0031] In other examples, the blade on the third U-shaped rod 23 is arranged obliquely relative to the vertical rod of the third U-shaped rod 23, so that the top end of the blade on the third U-shaped rod 23 is located outside the bottom end.

[0032] When stirring, the frame paddle structure rotates, and under the action of the vertical rod, the mixture can be concentrated inside the frame paddle structure after being formed into a vortex by high-speed rotation, that is, through the rotation of multiple groups of vertical rods, a vortex is formed inside the vertical rod, and under the action of the vortex, the mixture continuously enters the inside of the vertical rod and is stirred by the blades on the inside of the vertical rod, thereby improving the stirring efficiency.

[0033] The frame paddle structure can cover a larger space in the mixing cavity, and the blades can stir the material in multiple dimensions. No matter the material at the bottom, middle or top of the container, it can be effectively stirred, avoiding material deposition or stratification.

[0034] The rotating blades 3 can generate strong shear force and convection effect on the material during the stirring process, which can quickly mix different components of the material uniformly, especially suitable for high-viscosity or solid particle-containing materials such as paint, adhesive, food sauce, etc.

[0035] For the material which is easy to precipitate, the blades on the third U-shaped rod 23 are inclined relative to the vertical rod of the third U-shaped rod 23, which can continuously stir the material at the bottom when stirring, and the stirred material can enter the vortex formed by the upper frame for further stirring under the guidance of the blades 3, preventing the solid particles or precipitated substances from accumulating at the bottom of the container, and ensuring the uniformity of the material.

[0036] The mixed stirring paddle structure of the embodiment can be used in containers of different shapes (such as cylindrical, square, etc.), and has wide adaptability to the viscosity range of the material, from low-viscosity liquid to high-viscosity paste, which can be effectively stirred. The paddle structure is fixed by a screw, and the simple structure design makes the paddle easy to disassemble and clean, facilitating maintenance. The overall paddle structure is a metal structure, which can provide a certain safety and reduce the risk of breakage during high-speed rotation.

[0037] In an optional example, the support plate 1 is a circular hollow plate structure, and different shaped through holes are arranged on the support plate 1 to form a hollow structure, effectively connecting the upper frame and the lower frame, improving the stirring efficiency and ensuring that the pulp can be fully and uniformly stirred.

[0038] Embodiment Two As shown in Figures 1-4 A beater, the container of the beater is a mixing cavity, the mixing cavity is provided with the mixed stirring paddle structure of the embodiment one, the output shaft end of the beater is located in the mixing cavity, and the output shaft end is fixedly connected with the connecting sleeve through a bolt, so that the installation of the paddle structure is realized. When the beater is started, the mixture in the container can be fully stirred.

[0039] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
