Technical Field
[0001] The utility model relates to the technical field of building materials, in particular to a carbon-fixing foam concrete curing box. Background Technique
[0002] Concrete is a common building material. Concrete refers to the general term of an engineering composite material that binds aggregates into a whole by a cementitious material. Usually, the term "concrete" refers to the use of cement as the cementitious material and sand and stone as aggregates. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. The concrete curing box is used for the constant temperature and humidity standard curing of concrete specimens.
[0003] After retrieval, foam concrete is a lightweight wall material containing a large number of closed pores formed by adding a chemical foaming agent or a physical foaming agent to a slurry made of a cementitious material, admixture, modifier, etc., and then mixing, stirring, casting, and natural curing. During the storage of foam concrete, a curing box is needed for its carbon-fixing curing. However, common foam concrete curing boxes have problems in unstable curing during use. For example, some foam concrete curing boxes need to rely on carbon dioxide to achieve carbon fixation during curing. During the carbon-fixing process, multiple materials need to be added, and the process of preparing carbon dioxide is relatively complex. Moreover, when the carbon dioxide content inside the curing box is too high, it will affect the use quality of the foam concrete inside. Therefore, there are problems in inconvenient stable and efficient carbon fixation.
[0004] There is an urgent need for a carbon-fixing foam concrete curing box to solve the technical defects mentioned in the above technology. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: the carbon-fixing foam concrete curing box not only enhances the performance strength of the curing box, but also improves the safety;
[0013] (1) By providing the main body of the curing box, the carbon dioxide generator and the gas storage tank, the platform built in the carbon dioxide generator can place small pieces of limestone. The limestone reacts with the dilute hydrochloric acid solution inside the carbon dioxide generator to produce carbon dioxide gas. The carbon dioxide gas generated inside the carbon dioxide generator can be discharged from the first air outlet and enter the inside of the gas storage tank from the second air inlet for storage. Subsequently, the carbon dioxide inside the gas storage tank can enter the inside of the main body of the curing box.

A first air inlet 4 is installed on the left side of the main body 1 of the curing box. A gas storage tank 12 is arranged on the left side of the main body 1 of the curing box. A carbon dioxide generator 9 is arranged on the left side of the gas storage tank 12. A first air outlet 8 is fixedly connected to the right side of the carbon dioxide generator 9. A second air inlet 10 is fixedly connected to the left side of the gas storage tank 12. A second air outlet 11 is fixedly connected to the right side of the gas storage tank 12. A platform 6 is arranged inside the carbon dioxide generator 9. A handle 7 is fixedly connected to the top end of the platform 6. An exhaust port 3 is installed on the left side of the rear end of the main body 1 of the curing box;
[0022] The inside of the carbon dioxide generator 9 is filled with dilute hydrochloric acid, and limestone is placed on the top end of the platform 6;
[0023] Specifically, as shown in Figure 1 and Figure 2 , the platform 6 built in the carbon dioxide generator 9 can place small pieces of limestone. The reaction between the limestone and the dilute hydrochloric acid solution inside the carbon dioxide generator 9 can produce carbon dioxide gas. The carbon dioxide gas generated inside the carbon dioxide generator 9 can be discharged from the first air outlet 8 and enter the inside of the gas storage tank 12 through the second air inlet 10 for storage. Subsequently, the carbon dioxide inside the gas storage tank 12 can enter the inside of the main body 1 of the curing box, and the carbon dioxide can contact with the foam concrete inside the main body 1 of the curing box to produce a carbonization reaction.
[0024] Embodiment 2: The first air outlet 8 and the second air inlet 10 are in through connection, and the second air outlet 11 and the first air inlet 4 are in through connection. The gas storage tank 12 is arranged between the carbon dioxide generator 9 and the main body 1 of the curing box;
[0025] Specifically, as shown in Figure 1 and Figure 3As shown, the carbon dioxide generated by the carbon dioxide generator 9 can enter the interior of the gas storage tank 12 along the second air inlet 10. The carbon dioxide inside the gas storage tank 12 can enter the first air inlet 4 along the second air outlet 11, and the carbon dioxide enters the interior of the curing box main body 1 from the first air inlet 4 to achieve carbon fixation.
[0026] Embodiment 3: A flow dividing device 5 is fixedly connected to the rear end of the first air inlet 4, a control valve 2 is installed on the flow dividing device 5, and a safety valve 13, a pressure gauge 14 and a pressure reducing valve 15 are installed on the top of the gas storage tank 12;
[0027] Specifically, as Figure 1 and Figure 4 shown, the carbon dioxide enters the interior of the gas storage tank 12 for storage. The pressure gauge 14 installed on the gas storage tank 12 can detect the pressure stored inside the gas storage tank 12. Once the pressure is too high, the pressure reducing valve 15 on the gas storage tank 12 can reduce the pressure inside the gas storage tank 12, and this structure improves the safety of carbon fixation of the equipment.
[0028] Working principle: When the present utility model is in use, limestone needs to be first placed inside the carbon dioxide generator 9. The built-in platform 6 of the carbon dioxide generator 9 can place small pieces of limestone. The reaction between the limestone and the dilute hydrochloric acid solution inside the carbon dioxide generator 9 can produce carbon dioxide gas. The carbon dioxide gas generated inside the carbon dioxide generator 9 can be discharged from the first air outlet 8 and enter the interior of the gas storage tank 12 through the second air inlet 10 for storage. Subsequently, the carbon dioxide inside the gas storage tank 12 can enter the interior of the curing box main body 1. The carbon dioxide contacts the foam concrete inside the curing box main body 1 to produce a carbonization reaction, thereby improving the efficiency of carbon fixation. The carbon dioxide enters the interior of the gas storage tank 12 for storage. The pressure gauge 14 installed on the gas storage tank 12 can detect the pressure stored inside the gas storage tank 12.
