Description

Technical Field

[0001] The present application relates to the technical field of protection of low-temperature heat exchange equipment, and in particular to a protection device for preventing the foundation of low-temperature heat exchange equipment from freezing and cracking. Background Art

[0002] In the prior art, the heat exchanger foundation lacked insulation protection, and the heat exchanger operated alternately every other day. While the equipment was in standby mode, ice and snow accumulated on the foundation and heat exchanger plates during operation. The thermal expansion and contraction caused by the repeated alternation between low and normal temperatures caused the concrete foundation to crack and pulverize, and the anchor bolts to rust, seriously impacting the equipment's safe operation. Conventional insulation was later added, but due to its instability, the insulation layer was often crushed by ice. Moisture seeping into the insulation layer also compromised the insulation, damaging the foundation of the low-temperature heat exchanger and making repairs time-consuming and labor-intensive.

[0005] Optionally, in some solutions, the support mechanism 1 is formed by welding aluminum plates.

[0006] The technical solution provided by this application may have the following beneficial effects:

[0013] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0015] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0016] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0017] In response to the above problems, an embodiment of the present application provides a protective device for preventing the foundation of low-temperature heat exchange equipment from freezing and cracking, which can provide thermal insulation protection for the foundation of the heat exchange equipment to avoid freezing and cracking or deformation of the equipment foundation.

The heat-insulating filling layer 2 adopts a low thermal conductivity material to isolate heat, and the waterproof mechanism 3 is sealed with a waterproof material to prevent liquid from entering the heat-insulating filling layer 2 to reduce the heat insulation effect and affect the protection effect. The guide groove 4 is used to guide away the liquid generated by the condensation of low-temperature air or other media to prevent the foundation surface from freezing and reducing the heat exchange efficiency. The hook 5 is welded to the support mechanism, and the heat-insulating filling layer 2 is supported and fixed by the hook 5 to prevent the heat-insulating filling layer 2 from accumulating in the lower position under the action of gravity, thereby ensuring uniform heat insulation and forming heat insulation protection for the foundation of the heat exchange equipment to prevent the equipment foundation from freezing or deformation.
