Description
Technical Field
[0001] This utility model relates to the field of precast concrete technology, and in particular to a steam curing temperature control system. Background Technology
[0002] Steam curing is a crucial step in the production of precast concrete components. For example, in tunnel construction, the quality of the precast invert plays a key role in the stability and durability of the entire tunnel structure. Steam curing is an essential step in the production of precast inverts, accelerating the hardening process of concrete and improving its early strength. However, current steam curing temperature control systems often lack precision. Sensors in a single direction struggle to detect the temperature in different areas within the entire steam curing space, easily leading to uneven heating of the precast concrete components and affecting their quality. To detect the temperature throughout the entire steam curing space, multiple sensors are typically used. The steam curing space needs to be determined based on the size of the required precast concrete components. When the steam curing space is large, installing sensors in different areas throughout the entire space significantly increases costs.
[0003] Therefore, this invention develops a steam curing temperature control system to solve the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide a steam curing temperature control system to solve the problems existing in the prior art, and to complete the detection of temperature and humidity in the steam curing space without increasing costs, so as to avoid uneven heating of concrete precast components.

[0007] Preferably, the air supply device is provided in the curing chamber at the positions corresponding to the bottom and side walls of the precast concrete component.
[0008] Preferably, at least one side wall of the curing chamber is provided with a door for the precast concrete components to enter and exit, and the side walls of the curing chamber without doors are all equipped with air supply devices.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] The purpose of this invention is to provide a steam curing temperature control system to solve the problems existing in the prior art, and to complete the detection of temperature and humidity in the steam curing space without increasing costs, so as to avoid uneven heating of concrete precast components.
[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This embodiment provides a steam curing temperature control system, such as Figure 1-2 As shown, it includes: a curing chamber 1, a steam generator 2, and an automated control system 8; the curing chamber 1 is used to store precast concrete components 5 to be steam-cured, such as inverts used in tunnel construction; a gas supply device 3 is installed in the curing chamber 1 at least at the middle position corresponding to the bottom of the precast concrete component 5; the steam generator 2 is connected to the gas supply device 3 and delivers steam to the curing chamber 1 through the gas supply device 3; multiple temperature and humidity sensors 4 are evenly distributed on the top of the curing chamber 1; the automated control system 8 is electrically connected to the temperature and humidity sensors 4 and the steam generator 2.
[0026] As a specific implementation of this embodiment, the temperature and humidity sensing device 4 is a high-precision temperature and humidity sensor.
[0027] Furthermore, such as Figure 1-2 As shown, air supply devices 3 are provided in the curing chamber 1 at the positions corresponding to the bottom and side walls of the precast concrete component 5;
[0028] Furthermore, the gas delivery device 3 includes at least one steam pipe and multiple nozzles installed on the steam pipe;
[0029] Furthermore, in order to facilitate the entry and exit of the precast concrete component 5 in the curing chamber 1, at least one side wall of the curing chamber 1 is provided with a door for the precast concrete component 5 to enter and exit, and air supply devices 3 are installed on the side walls of the curing chamber 1 that do not have doors.
[0030] Furthermore, in order to fill all the steam pipes with steam through a steam generator 2; each steam pipe is interconnected, and one of the steam pipes is connected to the steam generator 2;
[0031] As a specific implementation of this embodiment, the curing chamber 1 has doors on two opposite side walls for the concrete precast components 5 to enter and exit; the doors are automatic roller shutter doors 7 for easy opening and closing; air supply devices 3 are installed on the other two opposite side walls of the curing chamber 1; the air supply devices 3 on the side walls include two steam pipes, and the air supply devices 3 at the bottom include one steam pipe; multiple nozzles are evenly distributed on each steam pipe; the nozzles are directed towards the concrete precast components 5 inside the curing chamber 1; through the air supply devices 3 on the side walls and the bottom, steam quickly and evenly fills the entire curing chamber 1; after the hot steam is ejected from the air supply devices 3 on the side walls and the bottom, it first fills the bottom of the curing chamber 1. The steam rises and eventually fills the entire curing chamber 1. Multiple temperature and humidity sensors 4 are evenly distributed on the top of curing chamber 1. Since the steam is emitted from the side walls and bottom, it first fills the bottom of curing chamber 1 and finally the top. Therefore, when all the temperature and humidity sensors 4 on the top of curing chamber 1 detect that the set temperature and humidity have been reached, the entire curing chamber 1 reaches the set temperature and humidity. The temperature and humidity sensors 4 transmit signals to the automatic control system 8. The automatic control system 8 automatically adjusts the steam generator 2 to ensure the stability and continuity of the steam supply, maintaining the set temperature and humidity within curing chamber 1 to cure the precast concrete blocks.
[0032] Furthermore, in order to reduce the energy consumption of the precast concrete block curing process, the curing chamber 1 has a double-layer structure; the inner layer of the curing chamber 1 is a cleaning layer with a smooth surface; the outer layer of the curing chamber 1 is an insulation layer; as a specific implementation of this embodiment, the cleaning layer is made of stainless steel; the insulation layer is made of polyurethane foam insulation board; the polyurethane foam insulation board is bonded to the stainless steel material.
[0033] Stainless steel has good corrosion resistance and heat resistance, and its smooth surface can prevent steam from corroding the curing chamber 1 and facilitate cleaning and maintenance of its surface. The outer layer of the curing chamber 1 is made of polyurethane foam insulation board, which can effectively reduce heat loss and reduce energy consumption.
[0034] Furthermore, such as Figure 2As shown, the steam generating device 2 is a high-efficiency boiler or an electric heating steam generator; the steam generating device 2 is installed outside the curing chamber 1; the steam generating device 2 is connected to the steam pipeline through the curing chamber 1 via an external pipe; a valve 6 is installed inside the external pipe; the valve 6 is electrically connected to the automatic control system 8; by adjusting the power of the heating element inside the steam generating device 2, the steam temperature can be adjusted to meet the different temperature requirements of the precast concrete components; the opening and closing degree of the valve 6 can be remotely or manually adjusted by the automatic control system 8 to precisely control the steam flow rate and meet the steam demand at different curing stages; placing the steam generating device 2 outside the curing chamber 1 can prevent the equipment from getting damp, short-circuiting, and causing electrical safety hazards.
[0035] As a specific implementation of this embodiment, the side wall of the curing chamber 1 is provided with a pipe opening for external pipes to pass through; in order to ensure the airtightness of the curing chamber 1, the external pipes and the pipe openings on the curing chamber 1 are sealed with foam adhesive.
[0036] Furthermore, all steam pipes installed on the sides of the curing chamber 1 are placed horizontally; the horizontal placement of the steam pipes can further enable the steam to preferentially fill the bottom of the curing chamber 1, ensuring that when the temperature and humidity sensor 4 on the top of the curing chamber 1 detects that the temperature and humidity at the top of the curing chamber 1 have reached the set temperature and humidity, the entire curing chamber 1 has reached the set temperature and humidity.
[0037] Example 2
[0038] Multiple temperature and humidity sensors 4 are evenly distributed on the side walls and bottom of the curing chamber 1. The temperature and humidity sensors 4 are electrically connected to the automatic control system 8. The rest is the same as in Example 1. Installing temperature and humidity sensors 4 on the side walls and bottom of the curing chamber 1 can more accurately detect the temperature and humidity of different areas in the curing chamber 1. When the space of the curing chamber 1 is small, only a small number of temperature and humidity sensors 4 need to be installed on the side walls and bottom of the curing chamber 1 to detect the temperature and humidity of the corresponding area. This will not increase the cost too much, and can detect the temperature and humidity of different areas in the curing chamber 1 more accurately.
[0039] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
