Description

Technical Field

[0001] This utility model belongs to the field of antique brick production, specifically an oxygen-isolated re-greening device for antique brick production. Background Technology

[0002] Most antique-style bricks are made of blue bricks. During the production of red bricks, the iron elements inside the brick blank easily form ferric oxide (Fe2O3) under a high-temperature oxidizing atmosphere, giving the brick its red color. The bluish-gray color required for antique-style bricks, however, requires the iron elements to be converted into ferrous oxide (Fe2O3) or magnetite (Fe3O4) in a reducing atmosphere after the red bricks have been fired. The traditional re-greening process involves placing the fired red bricks in a sealed space, then piling sawdust, straw, and other reducing fuels at the bottom of the space and igniting them. The combustion of these fuels consumes oxygen in the space and produces reducing gases such as carbon monoxide, causing the ferric oxide in the bricks to undergo a chemical reaction in the oxygen-deficient and reducing atmosphere. However, this traditional method has many shortcomings. The sealed space has poor oxygen isolation, allowing outside air to easily penetrate and affecting the sufficiency of the reduction reaction. Furthermore, the ash and impurities produced by the fuel combustion easily adhere to the brick surface, increasing subsequent cleaning steps. Additionally, the initial brick temperature during the re-greening process is nearly 1000℃; ash and impurities adhering to the brick surface at this high temperature may form defects after cooling, thus affecting the quality of the bricks. Utility Model Content

[0003] This utility model provides an oxygen-isolated re-greening device for the production of antique bricks, which solves the defects in the prior art.

[0004] This utility model is achieved through the following technical solution:

[0005] An oxygen-isolated re-greening device for producing antique-style bricks includes a housing. A lifting ring is located at the center of the top of the housing. A brick moving seat is located below the housing. A placement groove is formed on the brick moving seat at a position corresponding to the bottom of the housing. The bottom of the housing can be inserted into the placement groove. Combustion material placement boxes are located on both sides of the lower part of the housing. One side of the combustion material placement box is fixedly connected to the inside of the housing. The side of the combustion material placement box away from the side connected to the housing has an opening. The opening of the combustion material placement box can be inserted into a combustion material placement drawer. The top of the combustion material placement box has an opening at a position corresponding to the combustion material placement drawer. A barrier net is provided at the top opening of the combustion material placement box.

[0006] The oxygen-isolated re-greening device for producing antique bricks as described above has a high-temperature resistant sealing layer between the shell and the placement tank.

[0007] As described above, the oxygen-isolated re-greening device for producing antique bricks has a cooling chamber inside the shell. One side of the bottom of the cooling chamber is connected to the water inlet pipe, and the other side of the cooling chamber is connected to the water outlet pipe.

[0008] As described above, in the oxygen-isolated re-greening device for producing antique bricks, the combustible material placement box and the combustible material placement drawer can be fixedly connected by a pin.

[0009] As described above, in the oxygen-isolated re-greening device for producing antique bricks, the lower part of the insertion rod of the pin is threaded, and the lower part of the insertion rod can be threadedly connected to the nut.

[0010] The advantages of this invention are as follows: In this invention, after the combustible material is placed in the combustible material placement drawer and inserted into the combustible material placement box, the ash and impurities from the combustion of the combustible material will not fly out of the combustible material placement box due to the setting of the barrier net. Furthermore, the barrier net will not affect the entry of air into the sealed environment, thus preventing the ash and impurities produced by combustion from easily adhering to the surface of the bricks, while also ensuring the normal operation of the re-coating process. Simultaneously, the bottom of the shell can be inserted into the placement slot, thereby improving airtightness and ensuring the normal operation of the re-coating process.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] An oxygen-isolated re-greening device for producing antique-style bricks includes a housing 1. A lifting ring 2 is located at the center of the top of the housing 1. A brick moving seat 3 is located below the housing 1. A placement groove 4 is opened on the brick moving seat 3 at a position corresponding to the bottom of the housing 1. The bottom of the housing 1 can be inserted into the placement groove 4. Combustion material placement boxes 5 are located on both sides of the lower part of the housing 1. One side of the combustion material placement box 5 is fixedly connected to the inside of the housing 1. The side of the combustion material placement box 5 away from the side connected to the housing 1 has an opening. The opening of the combustion material placement box 5 can be inserted into the combustion material placement drawer 6. The top of the combustion material placement box 5 has an opening at a position corresponding to the combustion material placement drawer 6. A barrier net 7 is installed at the top opening of the combustion material placement box 5. When using this invention, after the red bricks are fired, they are quickly moved out of the kiln while still hot via the brick moving seat 3. Then, the shell 1 is lifted and moved above the brick moving seat 3 by the lifting device and the lifting ring 2, and slowly lowered so that the bottom of the shell 1 can be inserted into the placement groove 4 to form a sealed environment. Since the temperature of the bricks is above 900℃ at this time, the combustibles in the combustibles placement drawer 6 will re-burn under the rapid temperature rise of the sealed environment, thereby consuming the oxygen in the sealed environment and accelerating the re-greening operation. After the combustibles are placed in the combustibles placement drawer 6 and inserted into the combustibles placement box 5, the ash and impurities after the combustibles are burned will not fly out of the combustibles placement box 5 due to the setting of the barrier net 7. At the same time, the barrier net 7 will not affect the air entering the sealed environment, thereby avoiding the situation where the ash and impurities produced by combustion easily adhere to the surface of the bricks, while ensuring the normal progress of the re-greening operation.

[0017] Specifically, in this embodiment, a high-temperature resistant sealing layer 8 is provided between the shell 1 and the placement groove 4. In this invention, after exiting the kiln, the high-temperature resistant sealing layer 8 is fixed at the bottom of the shell 1 to increase the airtightness of the shell 1 and the placement groove 4 after insertion and mating, ensuring the normal operation of the re-greening process.

[0018] Specifically, in traditional brick-re-greening operations, water spraying is used to quickly cool the bricks. However, if the water mist comes into contact with the hot bricks, it may cause defects on the brick surface, affecting the quality of the bricks. To overcome this problem, the housing 1 in this embodiment is equipped with a cooling chamber 9. One side of the bottom of the cooling chamber 9 is connected to the water inlet pipe 10, and the other side of the cooling chamber 9 is connected to the water outlet pipe 11. In this utility model, the water inlet pipe 10 is connected to a tap water pipe through a flexible hose. If the power is insufficient, a water pump can be added to make the water flow quickly through the cooling chamber 9 and out through the water outlet pipe 11, thereby achieving rapid cooling while ensuring the quality of the bricks. The cooled water can also be recycled for mixing raw materials in brick production, thereby achieving full utilization of resources.

[0019] Furthermore, since the stability of the combustible material placement box 5 and the combustible material placement drawer 6 after being plugged together is poor, they may separate during the process of the housing 1 being lifted and moved. In order to overcome the above problem, the combustible material placement box 5 and the combustible material placement drawer 6 described in this embodiment can be fixedly connected by a pin 12. In this utility model, the combustible material placement box 5 and the combustible material placement drawer 6 can be easily fixed by the pin 12, thereby improving their stability during use.

[0020] Furthermore, since significant shaking of the housing 1 during use may cause the insertion rod 13 of the pin 12 to separate from the pin nose, thus rendering it unable to provide a fixing function, this embodiment provides a threaded lower part of the insertion rod 13 of the pin 12 to overcome this problem. The lower part of the insertion rod 13 can be threadedly connected to the nut 14. In this utility model, the threaded connection between the nut 14 and the lower part of the insertion rod 13 prevents significant shaking of the housing 1 from causing the insertion rod 13 of the pin 12 to separate from the pin nose, thereby improving the stability of the combustible material placement box 5 and the combustible material placement drawer 6 during use.

[0021] Preferably, in this embodiment, all components are made of high-temperature resistant materials, and the top of the combustible material placement box 5 and the combustible material placement drawer 6 are made of metal materials that are resistant to high temperatures and have good thermal conductivity, so as to ensure that the heat of the brick itself can be quickly transferred to the combustible material in the combustible material placement drawer 6 through the environment, thereby ensuring the greening efficiency.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
