In this curing, most of the artificial curing except natural curing is cured by using fossil fuels, and it emits air pollutants generated in the combustion process of fossil fuels, and also generates considerable amount of water resources by using steam by heating water. This is necessary. The water resources used as steam are not only released as obstacles that cause water pollution in the process of condensation and reduction into water, but also a large amount of energy is input for curing the state of water to steam and used for curing. Because of the excessive energy was used for curing.

The present invention avoids the wet, dry curing method using the conventional steam and dry curing method using the heat of combustion to induce and promote the hydration reaction by cyclically and continuously circulating by using a virtuous cycle curing system and an electric curing device to reuse the heat of hydration By curing it, it is possible to achieve the original purpose of curing of concrete products without receiving water and steam from the outside of the curing room.
In particular, it aims to curb unnecessary use of valuable groundwater resources and prevent excessive use of energy, and to cure environmentally and economically while preventing the causes of air pollution and water pollution.
(C) a means of solving the task;

Description

Method that improve health concrete manufacture because is cycled using electric heat curing apparatus without suppling water and steam from curing room outside}

The present invention is to achieve the object of curing in an eco-friendly and economical way for the concrete products molded by using a mold and mold by placing a variety of concrete block products, such as interlocking, retaining wall, revetment, vegetation block and reinforced soil In order to cure concrete products by circulating using an electric curing device without supplying water and steam from the outside of the curing room,

In particular, the present invention relates to a circulation curing method for inducing and promoting a hydration reaction of concrete products by supplying a heat source with an electric curing device while virtuous circulation using only water contained in a cast or molded concrete product.

The curing room usually secures the curing room in a certain space by using sandwich panel or tent and other shielding materials, and loads the product inside the shielded curing room to cure the air. It exists in a mixed state of air, that is, wet air state.

In the present invention, the wet air is sucked into the blower of the electric curing device and circulated and supplied, and then gradually warmed at the initial 70 ° C. using the heater device to regenerate the heated air source at 200 ° C. to 300 ° C., and re-supply it to the curing room. The temperature in the curing room increases and the temperature of the concrete product increases, so that the cement component and water of the product cause spontaneous hydration reaction, and the product promotes curing along with the generation of heat of hydration.

The heat of hydration generated during the curing process is suctioned again by using the electric curing device and warmed up by the heater device, thereby increasing the temperature of the curing room product by continuously repeating the virtuous cycle of supplying the regenerated heat source to the curing room again. The hydration reaction between cement and water is continuously promoted and the curing progresses.

The present invention continuously circulates the heat of hydration and saturated moisture discharged from the product through the virtuous cycle, and is sucked back into the electric curing device, regenerated to a temperature of 200 ° C to 300 ° C, and re-supplied to the curing room, and the temperature of the product naturally rises again. As a curing method that further promotes the hydration reaction to achieve the original purpose of curing, it circulates using an electric curing device without supplying water and steam from the outside of the curing room to induce and promote curing of concrete products. Curing method using the process.

The curing method using the curing system and the electric curing device will be described in detail as follows.

First of all, the concept of curing is to inhale the humid air naturally generated inside the curing room and to supply the regenerated heat source that is heated and regenerated through the electric curing device to the curing room repeatedly and continuously. In order to prevent rapid temperature change of the electric curing device and the product, curing is performed at intervals of sequential temperature and time of 70 ° C to 100 ° C in the first step, 150 ° C to 200 ° C in the second step, and 300 ° C to 300 ° C in the third step. When supplied to the room, the temperature of the curing room increases with the temperature of the curing room, and the product mixed with cement and water causes a hydration reaction by itself, and the curing of concrete products occurs. The product inside the nursing room through a curing process that raises the temperature of the curing room and the product through a series of repetitive and continuous cycles in which the hydration heat discharged from the curing process is sucked back into the electric curing device and re-heated and supplied. Cyclic curing using the electric curing device to induce and promote the hydration reaction by water alone to achieve the original purpose of curing the strength and durability of concrete without supplying water and steam from the outside Way.

Concrete products are classified into dry products and wet products according to the types of products, and are classified into wet curing and dry curing according to the curing process and curing method of concrete products.

The conventional curing method is broken down into the wet curing method by heating the water to generate steam and curing the steam using heat radiators such as pipes or radiators and dry curing using the radiant heat, and dry curing using the burner's combustion heat directly. It can be categorized into dry curing using electric energy and natural curing using natural environment, and it is cured in various ways according to the types and items of concrete products.

However, among these curing methods, steam is generated in dry curing using radiant heat through pipes and heat radiators through wet curing and steam, which uses water as a fruit and applies steam and heat to generate steam by spraying directly onto concrete products. Steam boilers and burners are used to burn fossil fuels and use the heat of combustion. In the combustion process, air pollutants are emitted and a considerable amount of water pollutants are produced by using steam.

In particular, curing using steam requires a lot of water to generate steam, and a large amount of state conversion energy is required to change the state of the water to steam by heating the water.

In dry curing, air pollutants are discharged in the conventional curing, which uses combustion heat directly or uses steam as a heat radiator to supply heat sources for curing.

In addition, the steam supplied to the curing chamber is liquefied to form condensed water, which condenses on the product or reacts with cement compounds and coloring pigments, causing it to leak into the curing chamber and cause water pollution. In addition, steam curing consumes a considerable amount of groundwater resources due to the use of steam.

Therefore, the present invention does not supply a separate water for curing, curing by using the moisture contained in the product to prevent waste of groundwater resources and to obtain the heat source required for curing unnecessary energy for the state change from water to steam Electric curing device without the use of water and steam from the outside of the curing room, which can prevent the waste caused by the supply of oil, and cause economic and eco-friendly concrete without causing water pollution and air pollution source. This is to cure concrete products by circulating using.

.

In conventional wet curing and dry curing using steam, water is used as a fruit and water is heated to make steam to cure. In this process, since the state of water to steam must be converted and supplied to the heat source of curing, a large amount of energy must be supplied according to the state transition.

In the present invention, it is to avoid curing by wasting unnecessary energy due to the state transition from water to steam.

In most fossil fuel curing systems, the exhaust gases generated during the combustion of burners and steam boilers are released into the atmosphere, causing air pollution. The present invention does not consume oxygen in the atmosphere by circulating curing using an electric curing device, so that it is environmentally friendly without generating an air pollution source.

In wet curing or dry curing using existing steam, water must be supplied to use steam, and the supply of water leads to waste and exhaustion of groundwater resources. The present invention is a cyclic curing method that does not use water and steam is a curing method using the moisture contained in the curing room product, that is, by inhaling wet air and warmed through an electrical curing device and supplying a regenerative heat source to the curing room and generated in the curing room. Hydration heat and water from the hydration reaction are sucked and warmed again, and a series of curing processes that are sucked and recovered and supplied again are cured in a repeated and continuous curing process, that is, a virtuous cycle curing method. By curing without receiving the supply, it is to prevent the waste of groundwater resources at the source and to protect the groundwater resources.

In wet curing of steam, condensed water is always generated inside the curing chamber due to the use of excessive saturated steam, and the condensate reacts with the cement component of the concrete product and its compound or pigment compound. And it is discharged outside the curing room, causing water pollution. The present invention does not generate unnecessary condensed water in the curing chamber by curing without supplying unnecessary water and steam for curing. Therefore, it is to enable environmentally friendly curing while preventing the discharge of unnecessary water pollution sources.

In the present invention, the concrete product formed by the combination of cement, aggregate, and water inhales and warms the humid air in the curing room using the characteristic environment existing in the curing room in the form of air, that is, moisture, that is naturally evaporated or discharged. It is designed to be used efficiently and economically to achieve the purpose of curing with the minimum curing heat source by supplying the minimum heat source necessary for curing by the repetitive and continuous method of supplying it by virtuous cycle curing method and electric curing device. to be.

As mentioned above, fossil fuel is used to heat water and generate steam to cure using the heat source of the steam, or use the heat of combustion of fuel as the heat source for curing, causing air pollution and water environmental pollution, and excessive unnecessary for curing. The use of water and steam causes groundwater resources to be wasted and cured in an uneconomical and inefficient way, but in the present invention, a method of curing concrete products by circulating using an electric curing device without using water and steam from the outside is used. Therefore, it aims to economically and ecologically cure while blocking water pollution and air pollution at the source and restraining the waste of groundwater resources.

As shown in FIG. 1, the moisture contained in the loaded product 1000 of the curing chamber 1100 is naturally discharged into the curing chamber, and the humid air inside the curing chamber is blown through the suction pipe 900 and the suction control valve 901. And the wet air of the curing room circulated and supplied to the electric curing device is heated while passing through the heater device 300 of the electrical curing device, regenerated to an elevated heat source, and supplied to the curing room 1100 and continuously circulated to circulate continuously. By raising the temperature of the product to induce and accelerate the hydration reaction of the product. At this time, the temperature supplied to the curing room is primarily 70 ° C. to 100 ° C., secondly 150 ° C. to 200 ° C., and thirdly 220 ° C. to 300 ° C., in order to prevent the temperature of the curing room from rising or changing rapidly. If the heating step by step until the temperature of the curing room 1100 is gradually increased and the temperature of the product 1000 is also naturally increased, the product mixed with cement and water occurs the hydration reaction itself and the heat of hydration generated during the hydration reaction In addition to the moisture generated in the discharge process is sucked into the blower 100 through the suction pipe 900 again and regenerated by the heated heat source again through the heater device 300 is again supplied to the curing room 1100 naturally As the temperature of the product is continuously raised, the concrete product (1000) is a series of curing that is to promote curing with a continuous hydration reaction. The cement product (1000) together with the supply heat source by supplying the regenerated heat source through the heater device 300 to the curing room (1100) again using a continuous and repetitive virtuous cycle of inducing and promoting the hydration reaction. It is a curing method using the circulation curing method that promotes curing by reusing moisture including the heat of hydration which is emitted by itself.

Therefore, in order to continuously cure the product in the curing room, the temperature required for the hydration reaction must be supplied. The temperature in the curing room is maintained at 30 ° C to 40 ° C for dry products, and for semi-dry products at 40 ° C to 50 ° C. If the wet product is kept at 60 ℃ to 70 ℃, the concrete product will spontaneously hydrate the moisture and cement components contained in the product and at the same time release the heat of hydration and reuse the hydration heat and saturated water in the curing room. The circulatory curing method is used to cure the product by further supplying the regenerated heat source by heating through the curing device to the curing room to further promote the hydration reaction.

That is, according to the type of the product 1000, the temperature supplied to the curing chamber 1100 is initially supplied from 70 ° C to 100 ° C and gradually raised to be heated and regenerated to a temperature of 200 ° C to 300 ° C to be cured. The temperature of the room is gradually increased, and naturally, the product is hydrated by the temperature rise and the heat of hydration is released, so that the temperature inside the curing room is continuously maintained. In this continuous virtuous cycle, the water generated from the product is saturated in the curing room, and the product is continuously hydrated in the process of hydrating heat and being absorbed or absorbed by the product depending on the temperature of the curing room. Curing is promoted because of this. Therefore, if the suction of the humid air of the curing room by the virtuous cycle curing method and supplied by heating and regenerating through the electrical curing device to increase the temperature of the curing chamber 1100 and the product 1000 in the curing chamber to reach the target hydration reaction temperature By doing this, you will have continuous healing. Therefore, even without receiving water and steam from the outside, the water contained in the product 1000 can induce and promote the hydration reaction, thereby not only achieving the original purpose of curing and improving the durability of the product, Eco-friendly and economical curing can be achieved without causing air pollution and water pollution and without wasting unnecessary groundwater resources.

As described above, in the present invention, as a circulating curing method for curing by varying the curing temperature according to the type and item of the curing room product, the humid air inside the curing room using an electric curing device having a power control unit, a temperature control unit, and a time control unit of the curing system control unit. The temperature of the curing room is increased while continuously circulating to maintain the dry product at 30 ℃ to 40 ℃, the semi-dry product at 40 ℃ to 50 ℃ and the wet product at 60 ℃ to 70 ℃ In other words, curing the concrete by using the electric curing device without using water and steam from the outside, characterized in that the curing temperature, time and the method of circulation curing according to the moisture content of the product to achieve the original purpose of curing. How to solve the problem is to solve the problem.

As described above, in the present invention, an existing fossil is used to induce and promote a hydration reaction in curing by inducing an artificial process of curing in order to make a durable concrete product having sufficient binding strength and strength. It is possible to escape from curing using steam and combustion heat using fuel, and to supply water and steam from the outside without moisture and natural moisture generated from the air and products inside the curing room, that is, using the air curing device and circulation curing method. It is for eco-friendly and economical curing to achieve the purpose.

In the existing steam curing of concrete products, the fossil fuel is burned and used to heat and evaporate water using combustion heat. Thus, fossil fuels emit air pollutants generated during the combustion process. In the case of wet curing where steam is supplied in a considerable quantity, the steam supplied to the curing chamber is condensed on the concrete products inside the curing chamber or is generated as condensate and leaks to the bottom of the curing chamber. And the effluent mixed with compounds such as pigments were discharged out of the factory outside the curing room, and became a source of water pollution.

In the present invention, in order to solve and prevent these problems, by using the electric curing device and the curing system only by the moisture contained in the concrete product itself by using a curing system without the supply of water and steam from the outside unnecessary water resources due to steam curing In addition to preventing the waste of water, it is possible not only to prevent the generation of water pollution sources due to the use of excessive water, but also to prevent the emission of air pollutants. In addition, in steam curing, state position conversion energy is required in order to change the state of water into steam. However, in the present invention, only the heat source required for the hydration reaction by the circulation curing method using an electric curing device without using water and steam from the outside is provided. The product itself has the advantage of preventing the use of unnecessary energy and economical curing by promoting curing by spontaneous hydration reaction.

In particular, it is possible to achieve the goal of curing and production of uniform products without the use of water, and excessive moisture from steam use condenses on the steel structure of the curing room to increase corrosion or to exhaust gases by direct combustion heat. It is economical because it prevents the phenomenon of shortening the service life by promoting oxidation corrosion of the mold or mold and freezing and cracking of winter products.

Therefore, the method of curing concrete products by circulating using an electric curing device without supplying water and steam from the outside of the curing room of the present invention protects the groundwater resources and prevents the emission of water pollution and air pollution. It is economical and environment-friendly curing method.

Each heater 3000 of the heating unit by the primary contactor in contact with the primary set temperature according to the instructions or set temperature of each step set in the thermostat to heat the heater unit 3000 of the heater unit 300 Supply the heat source to the curing room 1000 to increase the temperature of the curing room 1100 and to prevent overheating and load of the instantaneous heater device 300 The time control unit is configured to contact the secondary contactor by the secondary set temperature of the raw temperature controller, and after the preset time elapses after the secondary contactor contacts, the third contactor contacts the heater device 300 of the electric curing apparatus. Sequential warming of the inhaled nursing room air is supplied to the curing room as a regenerated heat source to induce and promote a hydration reaction to proceed with curing.

According to the temperature of the curing room set for each stage, each magnetic contactor reaching the curing target temperature of 3 stages is blocked and controlled. When the curing temperature set to the highest curing target temperature is reached, all the magnetic contactors are blocked and all the heaters 3000 The supply of power is stopped. At this time, the blower 100 continues the latent heat remaining in the heater device 300 and ends after performing a post purge by the set time controller for a predetermined time. After the blower 100 is turned off and curing is completed, internal latent heat remaining inside the curing apparatus 300 is generated or if the heat is reversed to the blower 1000 so that the motor and axial flow of the blower 100 may be damaged.

When curing is performed by the set temperature of the temperature controller and the heater 3000 is heated by the magnetic contactor according to the temperature set for each step, and the temperature of the curing chamber 1100 reaches the final set temperature, the blower 100 is post-purged. After executing the circulation is finished and enters the standby state and the temperature of the curing room 1100 again falls below the set temperature for each step, the blower 100 is started and circulates the humid air of the curing room for the set time and set After a period of time, each of the magnetic contactors is sequentially contacted by the temperature controller of the temperature controller. The heated and regenerated heat source is heated to the curing chamber 1100 through the heater device 300 to hydrate the product 1000. Continued induction of the reaction promotes curing.

The curing system control unit may control the temperature setting of the curing room 1100 and attach a time timer to terminate the system process of curing separately from the curing temperature when a certain curing time has elapsed by the time set with the temperature control unit. It is configured to be controlled by the curing time, and the temperature control unit is configured to be constrained by the time control unit, it is configured in parallel with the 24-hour control unit that can be produced during the day and curing as time curing at night as necessary.

There are various kinds of concrete products to be cured, so curing only by temperature control depends on the curing quality or economic effect. If curing products are cured by curing temperature control and the products to be cured can be cured with time control, Curing is controlled through the control, and the curing time necessary for producing the product during the daytime and curing using the night time can be started and finished by night setting without time constraints. The curing system control unit 1500 is configured to cure an optimal product by curing with a plurality of control systems.
