Description

Technical Field

[0001] This invention relates to the field of container heating technology, and in particular to a steam heating device and container device. Background Technology

[0002] There are two main types of methods commonly used for heating containers: electric heating and conduction heating. Electric heating or conduction heating is generally used to heat the solution inside the container. In container heating, from the perspective of economy, safety and reliability, conduction heating is the most commonly used. It involves heating the target medium by conducting heat through a medium (such as a jacket) using steam or hot water.

[0003] Currently, container heating technology is relatively mature, especially the use of high-temperature steam to heat containers by installing steam heating devices on them. However, these steam heating devices generally require valves or control via steam pipelines (e.g., valves on the steam pipeline) to prevent the solution in the container from flowing back into the steam heating device, thus ensuring heating efficiency and stability. Both installing valves on the steam heating device and relying on steam pipelines for control require additional structures (such as valves), resulting in a waste of manpower and resources. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0043] Example 1

[0044] Please see Figures 1 to 7 The present invention provides a steam heating device 2, the steam heating device 2 comprising:

[0045] The main body 4 is a barrel-shaped structure with openings at both ends and a hollow interior; one end of the main body 4 can be connected to a steam pipe (not shown);

[0046] The contouring structure 5 is located at the other end of the main body 4 (i.e., the end of the main body 4 away from the steam pipe); the contouring structure 5 may include multiple contouring parts 7, each of the contouring parts 7 including a guide petal 72, each of the guide petals 72 being arc-shaped; the multiple guide petals 72 are arranged circumferentially along the end face of the main body 4, the multiple guide petals 72 converge into a hollow cone shape when subjected to external force on the outer surface, and separate when subjected to external force on the inner surface.

[0047] In the steam heating device 2 of the present invention, by setting the contour structure 5 including the guide vane 72, the guide vane 72 separates when its inner surface is subjected to external force (such as the pressure of gas or liquid) (that is, the inner surface of the guide vane can deflect to one side when subjected to external force), so that the contour structure 5 opens, and when its outer surface is subjected to external force, it converges into a hollow cone shape, so that the contour structure 5 closes. The unidirectional conduction function can be achieved without changing the original volume. When the steam heating device 2 is used to heat the solution in the container, the solution in the container can be prevented from flowing back into the steam heating device 2. The heating effect and heating stability can be ensured without the need for additional valves, thereby saving manpower and material resources.

[0048] As an example, such as Figures 4 to 6 As shown, each of the contouring components 7 may also include a positioning component 71, which is integrally connected to the guide vane 72; the plurality of positioning components 71 are arranged in a ring along the circumferential direction of the end face of the main body 4; the contouring structure 5 is installed in the main body 4 via the positioning component 71.

[0049] As an example, the drainage valve 72 has a concave arc (not shown) on its outer surface near the positioning member 71. Referring to the operating principles of heart valve stents and heart valves, the drainage valve 72, by having a concave arc on its outer surface near the positioning member 71, will converge towards the center when its outer surface is subjected to pressure (for example, the pressure of liquid in a container acting on the outer surface of the drainage valve 72). At this time, the outer surface of the drainage valve 72 near the positioning member 71 has excellent pressure resistance and support properties.

[0050] As an example, the material of the contouring component 7 is nickel-titanium alloy, spring steel or copper alloy; that is, the material of the positioning component 71 and the material of the guide vane 72 can both be nickel-titanium alloy, spring steel or copper alloy.

[0051] As an example, the guide petal 72 can be regarded as a combination of multiple arcs with different inner diameters connected together, and the inner diameter of the guide petal 72 gradually decreases from the positioning member 71 to the end away from the positioning member 71.

[0052] As an example, the number of the contouring components 7 included in the contouring structure 5 can be set according to actual needs. For example, the number of the contouring components 7 included in the contouring structure 5 can be two, three, four or even more.

[0053] Specifically, the angle of each of the contouring components 7 is 360° / n, where n is the number of contouring components 7 in the contouring structure 5; taking the number of contouring components 7 in the contouring structure 5 as an example, the angle of each of the contouring components 7 is 120°.

[0054] For example, please refer to Figure 6 One end of the positioning member 71 is provided with a protrusion 74, and the other end is provided with a groove 73. Adjacent positioning members 71 are fixedly assembled via the protrusion 74 and the groove 73. That is, the protrusion 74 and the groove 73 are used to fix the assembly between two adjacent contouring members 7, making it easier for the contouring structure 5 to be installed on the main body 4.

[0055] As an example, please combine Figures 1 to 3 See Figure 4 The main body 4 includes a front compartment 41, the positioning element 71 is inserted into the front compartment 41, and the hollow channel in the front compartment 41 is connected to the interior of the contour structure 5.

[0056] As an example, the inner side of the front compartment 41 is provided with a first annular boss (not shown); the outer side of the positioning member 71 is provided with an annular groove (not shown) or a second annular boss (not shown). The positioning member 71 is engaged with the interior of the front compartment 41 via the annular groove or the second annular boss to ensure the connection between the contouring member 7 and the main body 4.

[0057] For example, please refer to Figure 2 and Figure 3 The main body 4 also includes a gathering section 42, in which a hollow channel is funnel-shaped, and the narrow end of the hollow channel is connected to a hollow channel in the front compartment 41. By setting the hollow channel in the gathering section 42 to a funnel shape, steam is facilitated to gather towards the center of the main body 4, thereby increasing the steam delivery speed, i.e., increasing the speed at which steam enters the container.

[0058] As an example, the contraction angle of the funnel-shaped hollow channel in the gathering part 42 is α, where 10° ≤ α ≤ 50°; specifically, α can be 10°, 20°, 30°, 40°, or 50°, etc. In this embodiment, 12° ≤ α ≤ 20°, for example, α can be 12°, 15°, or 20°, etc.

[0059] For example, please refer to Figure 4 The steam heating device 2 may further include a limiting member 6, which is a barrel-shaped structure with open ends and a hollow interior. The limiting member 6 is fitted around the outer periphery of the end of the front chamber 41 where the contour structure 5 is located, and the guide vane 72 extends to the side of the limiting member 6 away from the front chamber 41. Specifically, the limiting member 6 is used to fix the contour structure 5 to the main body 4 to ensure the stability of the contour structure 5; the limiting member 6 can also prevent tearing or damage to the root of the contour structure 5 to ensure the lifespan of the contour structure 5.

[0060] As an example, such as Figure 1 and Figure 2 As shown, the steam heating device 2 may further include a turbulence section 3, which is a barrel-shaped structure with open ends and a hollow interior; the turbulence section 3 is fitted onto one end of the main body 4 where the contour structure 5 is provided; the end of the guide vane 72 away from the main body 4 extends into the turbulence section 3.

[0061] The flow-dissipating part 3 is connected to the main body 4, which can also fix the contouring structure 5.

[0062] As an example, the widths of the openings at both ends of the turbulence section 3 are different, and the wide end of the turbulence section 3 is fitted onto the end of the main body 4 where the contour structure 5 is located.

[0063] Specifically, the flow-deflecting part 3 is a hollow, barrel-shaped structure with a large opening at one end and a small opening at the other end; the large opening of the flow-deflecting part 3 is connected to the main body 4. Specifically, the connection method between the flow-deflecting part 3 and the main body 4 can include, but is not limited to, threaded connection, snap-fit, and welding. These connection methods are robust and reliable, simple and convenient to operate, and inexpensive, possessing good economic attributes and performance.

[0064] As an example, the turbulence-disrupting part 3 can be a complete hollow cylindrical structure, or it can be formed by splicing two arc-shaped structures with semi-circular end faces.

[0065] As an example, the sidewall of the turbulence-disrupting part 3 is provided with multiple through holes (not shown), which are arranged at intervals along the extension direction and circumferentially of the turbulence-disrupting part 3. When the steam heating device 2 is used to heat the solution in the container, when the high-temperature steam enters the container through the main body 4, the contour structure 5, and the turbulence-disrupting part 3, a pressure difference effect is generated under the action of the high-speed airflow. This forces the solution inside the container into the range of the high-speed airflow and back into the container through the multiple through holes, causing the solution to tumble near the turbulence-disrupting part 3, accelerating the temperature radiation of the solution inside the entire container, and improving the heating efficiency.

[0066] As an example, the profiling part is prepared by the following method:

[0067] Design and create injection molds for contoured parts;

[0068] The liquid casting material is poured into the injection mold, cooled, and then the injection mold is removed to obtain the blank.

[0069] The blank is cut to remove excess material, resulting in a semi-finished profiling part;

[0070] The parameters of the semi-finished copying part are measured. If the measurement results do not meet the processing requirements, the semi-finished copying part is corrected and the parameters are measured again until the parameters of the semi-finished copying part meet the processing requirements.

[0071] The semi-finished model part is then ground and polished after measurement to make its surface smooth.

[0072] The semi-finished contoured part, after grinding and polishing, is electroplated to obtain the contoured part;

[0073] The profiling parts are inspected to select those that meet the requirements.

[0074] Specifically, the processing method of the contouring component 7 in the contouring structure 5 may include the following steps:

[0075] S10: By designing a contour mold to form an injection mold that meets the requirements of the blank, the high-temperature liquid material to be poured is poured into it, and after the liquid cools naturally, the blank obtained from the injection molding is removed.

[0076] S11: Cut the blank to remove excess material, which then becomes a semi-finished model part;

[0077] S12: Perform parameter measurements on the semi-finished contour parts, including checking whether the length, width, height, inner angle, and outer wall side angles meet the processing requirements;

[0078] S13: Grind and polish the semi-finished contour parts to achieve a smooth surface;

[0079] S14: Electroplating is performed on the semi-finished profiled parts after the surface is smoothed to prevent the surface from rusting when in contact with high-temperature steam or the solution inside the container during the subsequent use of the product, so as to obtain the final product, i.e. the required profiled parts.

[0080] S15: Conduct a final inspection on the completed profiling parts, and store those that meet the requirements for future use.

[0083] Container 1, the interior of which is provided with a receiving cavity (not shown);

[0084] As described in Embodiment 1, the steam heating device 2 extends from the outside of the container 1 through the side wall of the container 1 into the receiving cavity, and the contour structure 5 is located inside the receiving cavity.

[0085] Specifically, one end of the main body connected to the steam pipe is located outside the container 1, and the contour structure 5 is located inside the container. When the steam heating device 2 also includes the turbulence-disrupting part 3, the turbulence-disrupting part 3 is also located inside the receiving cavity.

[0086] As an example, the outer circumferential surface of the main body 4 is connected to the container 1. The specific connection method can include any one of threaded connection, snap-fit ​​and welding. These connection methods can firmly and reliably fix the main body 4 to the container 1, and are simple and convenient to operate, low in price, and have good economic attributes and practical performance.

[0087] As an example, the number of steam heating devices 2 is multiple, and the multiple steam heating devices 2 are arranged at intervals along the circumference and / or height of the container 1. Specifically, the multiple steam heating devices 2 can be arranged in a single layer along the circumference of the container 1, or they can be arranged in multiple layers along the height of the container 1, with each layer including multiple steam heating devices 2 arranged at intervals along the circumference of the container 1.

[0088] Taking the steam heating device 2, which includes a main body 4, a contoured structure 5, a limiting member 6, and a flow-disrupting part 3, as an example, the configuration method of the container device of the present invention may include the following steps:

[0089] S20: Connect the positioning member 71 of the plurality of contouring parts 7 obtained in Embodiment 1 to obtain a contouring structure 5 with a radius of 360°.

[0090] S21: Install the contouring structure 5 on the main body 4 (the positioning member 71 of the square structure 5 and the inner side of the front compartment 41 are provided with mutually fixed opposing members, such as a first annular boss, an annular groove or a second annular boss, to limit the position of the contouring structure 5 on the main body 4).

[0091] S22: Install the limiting component 6;

[0092] S23: Install the airflow spoiler 3;

[0093] S24: Install the assembled steam heating device 2 onto the container 1.
