Description

Technical Field

[0001] In many industrial production processes, materials need to be processed in tanks, such as for defoaming, mixing, and chemical reactions. These processes are often accompanied by temperature increases, especially during high-speed centrifugal motion. Friction between the material and the tank wall, friction between materials, and exothermic reactions occurring within the material all generate additional heat. If this heat cannot be dissipated effectively and promptly, the temperature of the tank and the material inside will become too high, potentially affecting the material's performance and quality, or even damaging the tank itself. Traditional cooling methods may include external water cooling, air cooling, or internal serpentine cooling to address the heat dissipation problem.

[0002] In recent years, centrifugal ventilation cooling technology has been applied. This method utilizes centrifugal force to draw in external cold air to cool the internal material tank. This technology typically involves a high-speed rotating cylinder with holes in its wall. The centrifugal force of the rotating cylinder draws external air through these holes, thereby cooling the internal material tank. This invention provides a centrifugal ventilation-based cylinder cooling device to achieve efficient cooling of the material tank. Background Technology

[0021] In existing technologies, centrifugal ventilation cooling utilizes centrifugal force to draw in external cold air to cool the internal material tank 2, such as... Figure 6 As shown, this technology typically involves a high-speed rotating cylinder 3 with holes 31 on its side wall. The centrifugal force of the rotating cylinder 3 draws external air into the cylinder 3 through the holes 31, thereby cooling the container holding the material inside. Existing holes 31 are typically cylindrical straight holes or, for example... Figure 6 The tapered hole in the middle presents the following problems during cooling: (1) Uneven airflow distribution: When air enters the inside of the barrel 3, it may concentrate in certain areas, resulting in uneven cooling, with some areas being overcooled and others undercooled. (2) Turbulence and energy loss: The edges of straight or tapered holes are prone to causing turbulence and eddies in the airflow, increasing flow resistance, reducing the effective cooling airflow, and also increasing energy loss. (3) Limited cooling efficiency: The above-mentioned opening design often makes it difficult to achieve efficient and uniform cooling, limiting its use in high-requirement applications.

[0022] To address the aforementioned issues, this application provides a material cooling device that can improve the uniformity and efficiency of centrifugal ventilation cooling.

[0023] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown in the figure, this application embodiment provides a material cooling device, including a material cylinder 1, which includes a cylinder body 101. The cylinder body 101 is a hollow cylinder or other rotating body. The side wall of the cylinder body 101 is provided with an opening 102 that penetrates the side wall of the cylinder body 101. One side of the opening 102 is an arc-shaped cross-section 103. The arc-shaped cross-section 103 extends from the outer side of the cylinder body 101 to the inner side of the cylinder body 101, so that when the cylinder body 101 rotates, the airflow outside the cylinder body 101 is introduced into the interior of the cylinder body 101 in a laminar flow state.

[0025] By designing one side of the opening 102 on the side wall of the cylinder 101 as an arc-shaped cross-section 103, the arc-shaped cross-section 103 extends from the outer side of the cylinder 101 to the inner side of the cylinder 101, so that when the cylinder 101 rotates, the airflow outside the cylinder 101 is introduced into the interior of the cylinder 101 in a laminar flow state, thereby cooling the material tank 2 inside the cylinder 101. The shape of the arc-shaped cross-section 103 helps to distribute the airflow more evenly to the peripheral area of ​​the outer wall of the tank 201, avoiding local overcooling or overheating of the tank 201, and making the cooling of the internal material more uniform. The arc-shaped cross-section 103 can guide the intake air to enter the interior of the cylinder 1 more smoothly and evenly, reduce turbulence and eddies, increase the contact area and time between the air and the material tank 2, thereby significantly improving the heat exchange efficiency.

[0026] In some embodiments, the cylinder 101 is provided with at least a pair of symmetrically arranged openings 102, wherein the axis of the cylinder 101 is located in the plane of symmetry of the pair of symmetrically arranged openings 102, which can ensure the uniformity of air intake inside the cylinder 101 and improve the uniformity of cooling.

[0027] In some embodiments, such as Figure 2 As shown, there are multiple openings 102, which are arranged in a circumferential array on the side wall of the cylinder 101, thereby improving cooling efficiency.

[0028] In some embodiments, such as Figure 5 As shown, the cross-sectional view of the arc-shaped section 103 in the direction perpendicular to the axis of the cylinder 101 is an arc-shaped tangent.

[0029] In this design, the center of the base circle of the arc-shaped tangent lies on the same straight line as the center of the cylinder. The inner surface of the cylinder forms a tangent with the base circle of the arc-shaped tangent. The intersection of the outer surface of the cylinder with the base circle and the tangent point of the inner surface of the cylinder with the base circle form an angle line. The angle between the tangent and the angle line is α, where α is 1~20°. The radius of the outer surface of the cylinder is R1, and the radius of the inner surface of the cylinder is R2. The ratio coefficient between R2 and R1 is k1, where k1 = R2 / R1 = 0.80~0.98.

[0030] Optionally, the base circle radius of the arc tangent is R3, and the ratio coefficient between R3 and R1 is k2, k2=R3 / R1=1.1~16.3.

[0031] In some embodiments, such as Figure 5 As shown, a rounded corner with a radius of curvature R4 is provided between the arc-shaped cut surface 103 and the outer surface of the cylinder 101. Optionally, the value of the radius of curvature R4 is 0.5mm to 5mm. The rounded corner is used to achieve a smooth transition between the arc-shaped cut surface 103 and the outer wall of the cylinder 101, reduce airflow resistance and reduce noise.

[0032] In some embodiments, such as Figure 2 As shown, the inner wall of the cylinder 101 is provided with fasteners, and the bottom of the cylinder 101 is provided with a support pad 107. The fasteners include a first fastener 104, a second fastener 105, and a third fastener 106 arranged sequentially from top to bottom. These fasteners are fixedly connected inside the cylinder 101 and can be fixed at specific positions on the cylinder 101 by welding, bolting, or other methods, for reinforcing and supporting the cylinder 101 and limiting the position of the internal container. The support pad 107 provides additional support and stability to the internal container. The cylinder 101 may also be provided with hexagonal socket head cap screws 109, which are used to fasten the entire cylinder 1 to the rotating shaft or frame.

[0033] In some embodiments, such as Figures 1 to 4 As shown, a material container 2 is provided inside the cylinder 101. The material container 2 includes a tank body 201, and there is a gap between the outer wall of the tank body 201 and the inner wall of the cylinder 101. When the cylinder 1 rotates, under the centrifugal force generated by the high-speed rotation of the cylinder 1, external air is drawn in through the opening 102 and flows through the gap between the tank body 201 and the cylinder 101, thereby flowing along the outer surface of the tank body 201 to cool the material container 2, thus achieving uniform and efficient cooling of the material inside.

[0034] In some embodiments, such as Figures 1 to 4 As shown, a fixing block 202 is provided on the outer wall of the tank 201, and the fixing block 202 is connected to the cylinder 101. The fixing block 202 is used to fix the tank 201 inside the cylinder 101, so that the tank 201 will not slide or rotate relative to the cylinder 101 when the cylinder 101 rotates, and can also form a certain gap between the tank 201 and the cylinder 101 to facilitate gas flow and heat dissipation. The fixing block 202 is designed to cooperate with the inner wall of the cylinder 101 to maintain an annular gap of appropriate size between the tank 201 and the cylinder 101.

[0035] In use, the material cooling device is fixed to the rotary drive equipment via the bottom of the cylinder 101, and the material cooling device rotates at high speed around the axis of the cylinder 101. Under the action of centrifugal force, since the linear velocity at the outer wall of the cylinder 101 is higher than that at the inner wall, external air is drawn into the opening 102 and enters the interior of the cylinder 101 along the arc-shaped tangent 103. Because the edge of the opening 102 is arc-shaped, the drawn-in airflow is effectively guided, forming a relatively stable and uniform airflow that flows along the gap between the tank 201 and the cylinder 101. This airflow exchanges heat with the outer wall of the tank 201 and the material tank 2, carrying away heat and achieving efficient cooling.

[0036] Compared with the prior art, the material cooling device of this embodiment has the following beneficial effects: (1) Improved cooling efficiency: The arc-shaped cut surface 103 can guide the intake air to enter the material cylinder 1 more smoothly, steadily and evenly, reducing energy loss, turbulence and eddies, increasing the contact area and time between air and material, thereby significantly improving heat exchange efficiency. Preliminary analysis shows that compared with Figure 6 The hole 31 shown in this embodiment can improve the cooling effect of the opening 102 with the arc-shaped cross-section 103 by 20% to 40%. (2) Improved cooling uniformity: The arc-shaped cross-section helps to distribute the airflow more evenly to the peripheral area of ​​the outer wall of the tank 2, avoiding local overcooling or overheating of the tank body, and making the cooling of the internal material more uniform. (3) Reduced noise and wear: The smooth arc-shaped cross-section 103 and the rounded corner design reduce the impact and turbulence when the air flows through the opening 102, which helps to reduce operating noise and reduce potential wear on the material of the cylinder 101. (4) Simple structure and easy to implement: This embodiment improves on the basis of the existing cylinder 1 structure, only requiring changes to the shape of the opening, which is easy to process, manufacture and install.

[0037] This utility model is not limited to the specific embodiments described above. For example, the number, size, and distribution of the openings 102 on the cylinder 101 can be adjusted according to specific cooling requirements. The specific parameters of the arc-shaped cross-section 103 (base circle 108 radius R3, guide corner radius R4) can also be optimized according to the size of the cylinder 101 and the rotation speed. The fixing methods of the material cylinder 1 and the material tank 2 can also have various variations. These all fall within the protection scope of this utility model.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
