Description

Technical Field

[0001] The invention relates to the field of heat preservation, and in particular to a heat preservation container and a production process of the heat preservation container. Background Art

[0002] In the production fields of food and chemical industry, insulation containers are often used in fermentation, activation and other processes. Conventional insulation containers are equipped with bottom heads, which are usually spun from the front. However, this installation method makes it necessary to assemble the welded outer skin of the insulation container in steps. First, the equipment body is processed, and then the insulation shell is inserted. After precise assembly, welding and polishing, the appearance quality of the equipment is difficult to control, the work is difficult, and the production progress is seriously affected.

[0003] In addition, due to the thermal expansion and contraction characteristics of the material, the temperature of the equipment body and the external temperature are usually inconsistent. A large temperature difference in the body leads to a large expansion, while a small temperature difference in the skin leads to a small expansion. The stress between the equipment body and the insulation shell cannot be released, resulting in deformation of the insulation shell, which may cause deformation of the appearance. It is also easy to cause the risk of negative pressure inside the equipment body. Summary of the invention

[0016] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0017] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in the figure, the present invention proposes a heat-insulating container, including a cylinder 1, a shell component sleeved on the outside of the cylinder 1, and a heat-insulating material 2, and the heat-insulating material 2 is filled between the cylinder 1 and the shell component. The shell component at least includes a heat-insulating shell 3 surrounding the cylinder 1 circumferentially and a bottom head 4 located at the bottom of the cylinder. Therefore, the heat-insulating material 2 is located between the heat-insulating shell 3 and the cylinder 1, and between the bottom head 4 and the cylinder 1. The bottom head 4 of the present invention adopts a reverse rotation head, which is different from a conventional head using frontal spinning. Specifically, the bottom head 4 has a first opening facing the bottom of the cylinder 1, that is, the bottom of the cylinder 1 is embedded in the bottom head 4 from the first opening. In this embodiment, the bottom head 4 has a first opening at one end, and an opening is also provided at the other end. That is to say, the bottom head 4 of the present invention has a truncated cone with approximately two openings at both ends. The bottom of the cylinder 1 is embedded in the bottom head 4 from the first opening at one end, and passes through the opening at the other end of the bottom head 4, in a partially exposed state, that is, the bottom end of the cylinder 1 is exposed, so that other structures (such as pipelines) can be directly connected or communicated with the bottom end of the cylinder 1. The edge of the first opening forms a first flange 41, and the first flange 41 extends in the direction away from the cylinder 1. In this embodiment, the first flange 41 extends downward. Different from the prior art, the heat-insulating outer shell 3 is sleeved on the outside of the cylinder 1, and the first opening of the bottom head 4 is embedded in the heat-insulating outer shell, so that the bottom head 4 is abutted against the heat-insulating outer shell 3. The heat-insulating outer shell 3 is fixed to the cylinder 1. Since the bottom head 4 has a first flange 41, the surface of the first flange 41, that is, the surface of the first flange 41 facing outward away from the bottom head 4, abuts against the inner wall of the thermal insulation shell 3, that is, the surface of the first flange 41 abuts against the inner wall of the thermal insulation shell 3 along the radial direction of the thermal insulation shell 3, so that the first flange 41 is in close contact with the inner wall of the thermal insulation shell 3.

[0020] When the heat-insulating container of the present invention is inserted into the heat-insulating outer shell 3, the bottom seal 4 is inserted into the inner wall of the heat-insulating outer shell 3, and the heat-insulating outer shell 3 and the bottom seal 4 are tightly in contact, and no welding is performed between the two. Specifically, the spinning radius R of the bottom seal 4 can be adjusted to avoid excessive gap between the bottom seal 4 and the heat-insulating outer shell 3, thereby affecting the heat-insulating effect. The spinning radius R can be set according to the structure of the heat-insulating container and the size of the heat-insulating outer shell, as long as the heat-insulating outer shell 3 and the bottom seal 4 are in contact and the first flange 41 is in close contact with the inner wall of the heat-insulating outer shell 3.

[0021] Traditional insulated containers use the front spinning of the bottom head, and the front spinning bottom head must be butted against the edge of the bottom side of the insulation shell. During the production of this type of insulation container, the shell components that are mounted on the outside of the cylinder can only be assembled in steps. First, the bottom head is processed, and then the insulation shell is produced according to the processing conditions of the bottom head to ensure that the installation dimensions match. During installation, the insulation material and the bottom head are first fixed, and then the insulation material is put on. After that, the insulation shell and the bottom head must be precisely assembled, welded, and polished to make the two join. The whole process is difficult to work, which seriously affects the progress of production, and the appearance quality of the insulation container is also difficult to control.

[0022] The thermal insulation container of the present invention adopts a reverse rotation head form, so that the manufacture of the thermal insulation shell and the installation of the cylinder can be carried out simultaneously. After the thermal insulation material and the cylinder are fixed, the thermal insulation shell is directly inserted and installed without the need for matching, welding and grinding, which effectively ensures the appearance quality of the thermal insulation container, greatly shortens the final assembly time of the thermal insulation container, and reduces the overall production cycle and production cost.

[0023] In addition, the use of the structure of the present invention can reduce the risk of deformation of the outer shell component caused by thermal expansion and contraction of the thermal insulation container and the risk of negative pressure forming in the cylinder.

[0024] Specifically, the bottom end of the insulation shell 3 in the insulation container of the present invention is also open. Due to the use of a reverse rotation head, the upper edge of the bottom head 4 is no longer mating with the lower edge of the insulation shell 3, so that the lower edge of the insulation shell 3 forms an exposed cutting edge. The cutting edge is relatively sharp and may bring hidden dangers. As a further improvement of the present invention, a circle of protective cover can be wrapped around the bottom edge of the insulation shell 3, that is, the edge of the bottom edge of the insulation shell 3 is wrapped by the protective cover to avoid the risks caused by the sharp cutting edge. The protective cover can surround the cutting edge at the bottom end of the insulation shell 3, and the protective cover itself will not cause secondary risks. Therefore, the protective cover can be a blunt structure, that is, a structure without sharp and sharp parts. Preferably, the present invention has a circle of round steel 31 wrapped around the bottom edge of the insulation shell, which has both protection and stability.

[0025] Specifically, the bottom end cap 4 of the present invention is not welded to the heat-insulating shell 3, so that the bottom end cap 4 is in a free state relative to the heat-insulating shell 3, so that the bottom end cap 4 can be freely extended and retracted when the cylinder 1 is extended and retracted. When the cylinder 1 expands, it will drive the bottom end cap 4 to move downward, causing the first flange 41 of the bottom end cap 4 to contact the bottom edge of the heat-insulating shell 3, especially when the bottom edge of the heat-insulating shell 3 is wrapped with round steel 31, if the first flange 41 contacts the round steel 31, it will cause the cylinder 1 and the heat-insulating shell 3 to generate a stretching stress. For this reason, in the vertical direction, a gap can be left at the edge of the first flange 41, that is, between the lower side of the first flange 41 and the bottom side of the heat-insulating shell 3, so as to leave a moving space for the bottom end cap 4 to move downward. The size of the gap can be adjusted according to the expansion amount of the general specific heat-insulating container equipment, and specifically, the above-mentioned gap is 10 to 30 mm. Furthermore, after assembly, the distance between the lower edge of the first flange 41 and the bottom edge of the heat-insulating outer shell in the vertical direction is 10 to 20 mm.

[0026] In the above embodiments, the shell assembly also includes a top seal 5 located at the top of the cylinder 1, and the top seal 5 has a second opening facing the cylinder 1, that is, the top of the cylinder 1 is embedded in the top seal 5 from the second opening. In this embodiment, the top seal 5 has a second opening at one end, and an opening is also provided at the other end. In other words, the top seal 5 of the present invention has a truncated cone with approximately two openings. The top of the cylinder 1 is embedded in the top seal 5 from the second opening at one end, and passes through the other end of the top seal 5, in a partially exposed state, so that other structures (such as pipelines) can be directly connected or communicated with the top of the cylinder 1. The edge of the second opening forms a second flange 51, which extends in the direction away from the cylinder 1. In this embodiment, the second flange 51 extends upward. Different from the prior art, the previous top seal will be installed by forward rotation, and the edge of the top seal is fixed to the insulation shell. The top seal 5 of the present invention adopts a reverse rotation seal, the insulation shell 3 is inserted into the cylinder 1, and the second opening of the top seal 5 is embedded in the insulation shell 3, and then the top seal 5 is welded to the inner wall of the insulation shell 3. Specifically, the second flange 51 is fillet-welded to the heat-insulating outer shell 3 .

[0027] In the prior art, the top head seal adopts a positive rotation method, and when the heat-insulating container is actually in operation, water will flow along the top head seal to the outer shell surface of the heat-insulating container to form water stains. In the above embodiment, the top head seal 5 adopts a reverse rotation head seal, and its second flange 51 can form a groove, so that when the heat-insulating container is actually in operation, water can be collected in the groove and then discharged through additional drainage structures such as pipes. Since the bottom head seal 4 already has a telescopic function, the top head seal 5 does not need to have a telescopic function. Welding the top head seal 5 to the heat-insulating outer shell 3 can also prevent liquid from entering the heat-insulating outer shell 3 and affecting the heat preservation.

[0028] Similarly, the gap between the top head 5 and the heat-insulating shell 3 can also be controlled by adjusting the spinning radius R. In addition, the spinning radius R of the top head 5 and the spinning radius R of the bottom head 4 are consistent in appearance.

[0029] As a further improvement of the present invention, a protective sleeve can be wrapped around the top edge of the heat-insulating outer shell 3 to avoid the risks caused by sharp cutting edges. The protective sleeve can not only surround the cutting edge at the top of the heat-insulating outer shell 3, but also the protective sleeve itself will not cause secondary risks. Therefore, the protective sleeve can be a blunt structure, that is, a structure without sharp parts. Preferably, the present invention has a circle of round steel 31 wrapped around the top edge of the heat-insulating outer shell, which has both protection and stability.

[0030] In the above embodiments, the heat preservation container further includes a support leg 6 for supporting and fixing the cylinder 1. In other embodiments, the support leg 6 can pass through the bottom seal 4 and the bottom seal 4 is welded to the support leg to achieve a fixed connection between the bottom seal 4 and the cylinder 1. In addition, the cylinder 1 in the above embodiments further includes a stirring device, which can be used for food processing.

[0031] The present invention also provides a production process for the heat-insulating container in each of the above embodiments, which at least includes the following steps:

[0032] A cylinder 1, a bottom end cap 4 and an insulating outer shell 3 are manufactured; the cylinder 1 is wrapped with the insulating material 2; the bottom end cap 4 is fixedly connected to the cylinder 1, and the insulating outer shell 3 is inserted into the insulating material 2 and the cylinder 1 so that the bottom end cap 4 abuts against the inner wall of the insulating outer shell 3.

[0033] After the above steps, other conventional installation steps are performed to complete the production and assembly of the thermal insulation container.

[0034] In the prior art, when producing and assembling the heat-insulating container, it is necessary to assemble and process the cylinder first. Generally, the bottom head is produced first, and then the matching heat-insulating shell is produced according to the bottom head. After the bottom head is fixed, the heat-insulating shell is put on, and the steps of matching, welding, and grinding are required. The production process of the heat-insulating container of the present invention does not need to produce the bottom head first and then the heat-insulating shell. The cylinder 1, the heat-insulating shell 3 and the bottom head 4 can be produced at the same time, saving time. And the heat-insulating shell can be directly nested and fixed on the outside of the cylinder, and the bottom head is abutted against the heat-insulating shell 3.

[0035] In the above embodiment, the heat-insulating outer shell 3 may be put on first and then the bottom head 4 may be installed, or the bottom head 4 may be put on and fixed first and then the heat-insulating outer shell 3 may be installed. Preferably, the bottom head 4 is installed first and then the heat-insulating outer shell 3 is installed.

[0036] Furthermore, in the production process of the above-mentioned heat-insulating container, after the heat-insulating shell 3 is inserted, the top seal 5 with the reverse rotation structure can be welded to the heat-insulating shell 3, and only simple correction is required without grinding. The distance between the heat-insulating shell 3 and the second flange 51 is controlled, and the edge of the second flange 51 is wrapped with round steel 31, and the round steel 31 on the top seal 5 is fixedly welded to the heat-insulating shell 3.

[0037] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
