Description

Technical Field

[0001] This utility model relates to the technical field of material cylinder devices, and in particular to a fully guided material cylinder. Background Technology

[0002] As a key piece of equipment in the production and storage of materials such as adhesives, the temperature control capability of the material tank directly affects the processing quality. Due to the needs of the production and processing technology, the materials in the material tank usually need to be heated or cooled. Traditional material tanks, such as the vinegar stirring device disclosed in Chinese invention patent CN110652913A, use a heating layer on the outer wall of the tank with heating wires installed inside to heat the materials in the tank. However, this device has significant drawbacks: first, the heating area is limited to the side wall, resulting in uneven heating of the materials and a temperature lag between the bottom and the center; second, it lacks a flow guiding design, relying solely on natural convection for heat exchange, resulting in low heat transfer efficiency; and third, it has a single function and cannot meet the need for rapid cooling. These structural defects not only prolong the process cycle but also lead to localized overheating or underheating of the materials, seriously affecting the homogeneity of the product. Especially in the processing of polymer materials that require precise temperature control, existing material tanks are unable to meet the process requirements, becoming a key bottleneck restricting the improvement of production efficiency and product quality. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a fully guided flow material cylinder, which has the effect of enhancing heat exchange efficiency and effectively solves the problems of uneven temperature control and low heat transfer efficiency of traditional material cylinders.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fully guided flow material cylinder, including an inner cylinder, a jacket sleeved outside the inner cylinder, and a first bottom plate fixed to the bottom of the jacket. A first guide cavity is formed between the side wall of the inner cylinder and the jacket, and a second guide cavity is formed between the bottom wall of the inner cylinder and the first bottom plate. The first guide cavity and the second guide cavity are connected. The bottom and top of the side wall of the jacket are respectively provided with a liquid inlet and a liquid outlet. The liquid inlet is connected to the second guide cavity, and the liquid outlet is connected to the first guide cavity.

[0005] As a further embodiment, a first guide plate is provided in the first guide cavity. The first guide plate extends spirally from bottom to top and spans between the side wall of the inner cylinder and the jacket to form a spiral flow channel. The spiral flow channel extends from the connection between the first guide cavity and the second guide cavity to the liquid outlet.

[0006] As a further embodiment, the second guide cavity is provided with multiple second guide plates, which are spaced apart between the bottom wall of the inner cylinder and the first bottom plate to divide the second guide cavity into multiple slow flow cavities. Adjacent slow flow cavities are interconnected, and the slow flow cavities near the liquid inlet are connected to the liquid inlet, while the slow flow cavities away from the liquid inlet are connected to the spiral flow channel.

[0007] As a further solution, multiple through holes are provided on the multiple second guide plates, and the multiple through holes connect adjacent slow-flow cavities.

[0008] As a further embodiment, a second bottom plate is fixed to the bottom of the inner cylinder, and the second guide plate is disposed between the first bottom plate and the second bottom plate.

[0009] As a further embodiment, both the jacket and the first base plate are covered with an insulation sleeve, forming a first inner cavity between the insulation sleeve and the jacket, and a second inner cavity between the insulation sleeve and the first base plate, with insulation cotton filling both the first and second inner cavities.

[0010] As a further solution, a handle is provided on the side wall of the inner cylinder.

[0011] As a further solution, casters are provided at the bottom of the first base plate.

[0012] The beneficial effects of this invention are as follows: After the heat exchange medium enters the second guide cavity from the inlet, it diffuses and fills the entire cavity. Since the first and second guide cavities are connected, it then enters the first guide cavity. Within the first guide cavity, the heat exchange medium flows upwards along the sidewall and is finally discharged from the top outlet. This flow path allows the heat exchange medium to act sequentially on the bottom and sidewalls of the material cylinder, forming a fully covered heat exchange interface. Furthermore, the design of preferentially filling the second guide cavity at the bottom avoids the problem of insufficient bottom heat exchange efficiency caused by differences in the specific gravity of the heat exchange medium in traditional structures. The double-layered cavities at the bottom and sidewalls of the material cylinder form a fully guided flow structure, eliminating the heat conduction blind spots present in traditional single-layer structures and achieving three-dimensional heat conduction. This significantly improves the uniformity of material heating or cooling and avoids material denaturation caused by localized temperature differences. The directional flow path shortens the heat exchange medium circulation time and improves heat transfer efficiency, thereby shortening the production cycle and improving product quality stability.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] In the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] As attached Figure 1 As shown, the present invention provides a fully guided flow material cylinder, including an inner cylinder 1, a jacket 2 sleeved outside the inner cylinder 1, and a first bottom plate 3 fixed to the bottom of the jacket 2. A first guide cavity 4 is formed between the side wall of the inner cylinder 1 and the jacket 2, and a second guide cavity 5 is formed between the bottom wall of the inner cylinder 1 and the first bottom plate 3. The first guide cavity 4 and the second guide cavity 5 are connected. The bottom and top of the side wall of the jacket 2 are respectively provided with a liquid inlet 6 and a liquid outlet 7. The liquid inlet 6 is connected to the second guide cavity 5, and the liquid outlet 7 is connected to the first guide cavity 4.

[0020] The inner cylinder 1 is a cylindrical container for holding materials such as adhesives. It can be made of welded stainless steel. Its sidewalls are spaced from the jacket 2 to form a first flow guide cavity 4. The top of the jacket 2 wraps around the outer wall of the inner cylinder 1 and is fixedly connected to it. Its bottom is assembled and fixed to the first base plate 3. The first flow guide cavity 4 is an annular space formed by the outer surface of the inner cylinder 1's sidewall and the inner surface of the jacket 2. The cavity thickness can be controlled by adjusting the diameter of the jacket 2. It guides the heat exchange medium (such as heat transfer oil or cold water) to flow along the sidewalls. The second flow guide cavity 5 is a flat cavity formed by the lower surface of the inner cylinder 1's bottom wall and the upper surface of the first base plate 3. It guides the diffusion of the heat exchange medium in the bottom region. The inlet 6 is a heat exchange medium inlet located at the bottom of the jacket 2's sidewall. It can be connected to an external pipeline using a flanged pipe fitting, allowing the heat exchange medium to enter the second flow guide cavity 5. The liquid outlet 7 refers to the heat exchange medium outlet located at the top of the side wall of the jacket 2, which allows the heat exchange medium to be discharged from the first guide cavity 4.

[0021] Specifically, after the heat exchange medium enters the second guide cavity 5 through the inlet 6, it diffuses and fills the entire cavity. Since the first guide cavity 4 is connected to the second guide cavity 5, it then enters the first guide cavity 4. Within the first guide cavity 4, the heat exchange medium flows from bottom to top along the sidewall and finally exits from the outlet 7 at the top. This flow path allows the heat exchange medium to act on the bottom and sidewalls of the material cylinder sequentially, forming a fully covered heat exchange interface. Furthermore, the design of preferentially filling the second guide cavity 5 at the bottom avoids the problem of insufficient heat exchange efficiency at the bottom due to the difference in the specific gravity of the heat exchange medium in traditional structures. The double-layer cavity at the bottom and sidewalls of the material cylinder forms a fully guided flow structure, eliminating the heat conduction blind spots present in traditional single-layer structures and achieving three-dimensional heat conduction. This significantly improves the uniformity of material heating or cooling and avoids material denaturation caused by local temperature differences. The directional flow path shortens the heat exchange medium circulation time and improves heat conduction efficiency, thereby shortening the production process cycle and improving product quality stability.

[0022] Furthermore, a first guide plate 41 is provided in the first guide cavity 4. The first guide plate 41 extends spirally from bottom to top and spans between the side wall of the inner cylinder 1 and the jacket 2 to form a spiral flow channel 42. The spiral flow channel 42 extends from the connection between the first guide cavity 4 and the second guide cavity 5 to the liquid outlet 7.

[0023] The spiral extension refers to the structure of the first guide plate 41 continuously spiraling upwards in the vertical direction. Specifically, the first guide plate 41 can be fixed between the outer wall of the inner cylinder 1 and the inner wall of the jacket 2 by welding or casting. This structure can force the heat exchange medium to flow along a spiral path to extend the movement trajectory. Furthermore, the first guide plate 41 spanning between the side wall of the inner cylinder 1 and the jacket 2 means that both ends of the first guide plate 41 are in close contact with the outer wall of the inner cylinder 1 and the inner wall of the jacket 2, respectively, to form a spiral flow channel 42.

[0024] Since the spiral flow channel 42 extends from the connection between the first guide cavity 4 and the second guide cavity 5 to the liquid outlet 7, when the heat exchange medium enters the second guide cavity 5 from the liquid inlet 6, it enters the spiral flow channel 42 through the connection. The continuous spiral structure of the first guide plate 41 forces the heat exchange medium to flow from the bottom to the top along the spiral direction. Since the path length of the spiral flow channel 42 is much greater than that of the straight flow channel, the contact time between the heat exchange medium and the side wall of the inner cylinder 1 is significantly increased.

[0025] The structure of the first guide plate 41 spanning both side walls eliminates the local turbulence zone in traditional annular flow channels, allowing the fluid to form a uniformly distributed laminar flow state throughout the spiral flow channel 42. As the heat exchange medium spirals upward, its flow direction continuously changes, leading to continuous disruption of the boundary layer and thus enhancing the heat transfer efficiency between the inner cylinder 1 sidewall and the heat exchange medium. If the heat exchange medium flows only unidirectionally in the vertical direction, this results in a short heat exchange contact time and dead zones. This application, through the design of the spiral flow channel 42, enables the heat exchange medium to form a multi-circulation flow path within the first guide cavity 4, which not only extends the heat exchange time but also promotes full contact between the heat exchange medium and the heat exchange surface through the centrifugal effect of the spiral upward movement, significantly improving the overall heat exchange efficiency. Furthermore, the spiral first guide plate 41 completely eliminates stagnation by forcing the heat exchange medium to flow in a directional manner.

[0026] Additionally, as attached Figure 2-3 As shown, this application further proposes that the second guide cavity 5 is provided with multiple second guide plates 51, which are distributed at intervals between the bottom wall of the inner cylinder 1 and the first bottom plate 3, so as to divide the second guide cavity 5 into multiple slow flow cavities 53. Adjacent slow flow cavities 53 are interconnected, and the slow flow cavities 53 near the liquid inlet 6 are connected to the liquid inlet 6, while the slow flow cavities 53 away from the liquid inlet 6 are connected to the spiral flow channel 42.

[0027] Specifically, after the heat exchange medium enters the slow-flow chamber 53 connected to the inlet 6, it flows sequentially through adjacent slow-flow chambers 53. Because adjacent slow-flow chambers 53 are connected by through holes 52 or gaps in the second guide plate 51, the heat exchange medium is forced to change its path multiple times during flow, gradually reducing its flow velocity and increasing the heat exchange time. Furthermore, through the staged diffusion within the slow-flow chambers 53, the heat exchange medium is evenly distributed in the second guide chamber 5. Finally, the heat exchange medium enters the spiral flow channel 42 from the slow-flow chamber 53 furthest from the inlet 6, at which point it has fully diffused and formed a uniform temperature distribution. Through the separation and connection of multiple stages of slow-flow chambers 53, the flow path of the heat exchange medium within the second guide chamber 5 is extended, improving heat exchange efficiency. Simultaneously, it avoids localized temperature differences caused by a single flow path, further enhancing heat conduction efficiency and resulting in a more uniform overall temperature distribution of the material, thereby improving production quality and processing efficiency.

[0028] Meanwhile, the multiple second guide plates 51 can also support the weight of the inner cylinder 1.

[0029] Furthermore, multiple through holes 52 are formed on the second guide plates 51, connecting adjacent slow-flow chambers 53. The second guide plates 51 can be made of stamped stainless steel sheet, and the holes distributed on their surface allow the heat exchange medium to flow between adjacent slow-flow chambers 53. The through holes 52 are through-holes formed on the surface of the second guide plates 51, establishing heat exchange channels between adjacent slow-flow chambers 53 through a physical penetration structure, allowing the heat exchange medium to interact simultaneously through multiple locations. When the heat exchange medium enters the second guide chamber 5 from the inlet 6, it flows sequentially through multiple slow-flow chambers 53. The heat exchange medium in each slow-flow chamber 53 not only flows along the main channel between the guide plates but also penetrates laterally into adjacent chambers through the through holes 52. This multi-path flow pattern increases the turbulence of the heat exchange medium, eliminates local temperature differences caused by a single flow direction, and thus improves the heating or cooling efficiency of the material inside the inner cylinder 1.

[0030] Furthermore, as shown in the appendix Figure 1-2 As shown, a second base plate 8 is fixed to the bottom of the inner cylinder 1. A second guide plate 51 is disposed between the first base plate 3 and the second base plate 8. The second base plate 8 serves to support the weight of the inner cylinder 1 and further transfers the weight to the first base plate 3 through the second guide plate 51. This structure provides vertical constraint for the second guide plate 51 through the clamping effect of the double-layer base plates. This structure is confined within the closed space formed by the two base plates, preventing the second guide plate 51 from shifting laterally due to the pressure of the heat exchange medium.

[0031] In addition, both the jacket 2 and the first base plate 3 are covered with heat-insulating sleeves 9. A first inner cavity 91 is formed between the heat-insulating sleeve 9 and the jacket 2, and a second inner cavity 92 is formed between the heat-insulating sleeve 9 and the first base plate 3. Both the first inner cavity 91 and the second inner cavity 92 are filled with heat-insulating cotton 93. The heat-insulating cotton 93 can reduce the outward heat conduction of the jacket 2 and the first base plate 3. Among them, the heat-insulating cotton 93, as a heat insulation material, plays a role in preventing heat from diffusing outward through its low thermal conductivity, thereby maintaining the temperature stability of the heat exchange medium in the first flow guiding cavity 4 and the second flow guiding cavity 5.

[0032] This application further proposes that a handle 11 be provided on the side wall of the inner cylinder 1, so that the operator can grip and apply force.

[0033] This application further proposes that casters 31 are provided at the bottom of the first base plate 3. The casters 31 enable the material cylinder to move and adjust its position, which significantly shortens the equipment layout time in the production process.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
