Abstract
Description
Technical Field
[0001] This utility model relates to a steam generator, specifically a portable concrete curing steam generator, belonging to the technical field of concrete component curing equipment. Background Technology
[0002] Newly poured concrete components typically require steam curing to ensure a normal or accelerated hardening process, thereby enhancing the concrete's strength. Existing steam curing equipment for concrete typically uses a separate steam generator and concrete container, with the container maintaining a sealed and temperature-controlled environment before introducing steam for curing. However, this approach has drawbacks: the connection between the two via pipelines leads to heat loss during steam transfer, causing condensation and significant steam loss (e.g., a steam generator for concrete curing in construction disclosed in Chinese Patent Document CN214273000U). Furthermore, to ensure even steam distribution within the container, multiple distribution pipes are required. During installation, each interface of the container must be sequentially connected to a distribution pipe, and the numerous interfaces increase the risk of leaks due to negligence. After curing, the equipment must be disassembled sequentially for transfer, making the entire process cumbersome.
[0003] Therefore, further improvements are needed. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a portable concrete curing steam generator that reduces steam loss, improves steam utilization, simplifies the operation process, has excellent sealing performance, and has a simple and reasonable structure.

[0006] Furthermore, the steam inlet has several components; each steam inlet includes a hollow column and an upper plate; the hollow columns are evenly distributed at the bottom of the component container; a steam outlet is provided at the bottom of the steam discharge seat; the steam outlet protrudes from the bottom of the steam discharge seat.

[0012] This utility model has the following advantages: the component container and the steam assembly in the chamber are connected through a steam discharge seat; during steam curing, due to the existence of the sliding mechanical seal mechanism, an excellent sealing environment can be maintained between the container and the chamber, reducing or even avoiding steam leakage; at the same time, when installing the container, there is no need to connect complex branch pipes, simply align the steam inlet at the bottom of the container with the sleeve on the steam discharge seat and insert it to complete the mechanical seal connection, and then place the concrete component in the container; finally, the steam discharge seat can be opened by the opening and closing mechanism to introduce steam upwards.
