Technical Field

[0001] This utility model relates to the technical field of autoclaved aerated concrete (AAC) block steam curing devices, specifically an AAC block steam curing device that reduces thermal pollution. Background Technology

[0002] The autoclaved aerated concrete (AAC) block autoclaving device is a core piece of equipment in the production process. Its main function is to use high-temperature and high-pressure steam to cause physical and chemical reactions in the AAC block, ultimately forming a finished product with stable properties.

[0003] Referring to Chinese Patent Publication No. CN209466429U, a gasified block autoclaving device is disclosed. The inner cavity of the autoclave is provided with a guide bucket and a support plate. The guide bucket is located above the support plate. The guide bucket and the support plate divide the inner cavity of the autoclave into a heat exchange chamber, an autoclaving chamber and an air inlet chamber from top to bottom. A heat dissipation pipe is provided in the heat exchange chamber. The top of the heat exchange chamber is connected to an exhaust pipe. The air outlet end of the heat dissipation pipe is connected to the exhaust pipe. The bottom end of the heat dissipation pipe is connected to the guide bucket. Several through holes are evenly provided on the support plate. A material hole is provided on one side of the autoclaving chamber. A sealing door is fitted on the material hole. In this invention, steam is used to autoclave the material in the autoclaving chamber. The waste steam generated after autoclaving enters the heat dissipation pipe under the action of the guide bucket and is then discharged through the exhaust pipe. The waste steam heats and treats the water in the heat exchange chamber through the heat dissipation pipe, thereby reducing the temperature of the waste steam, reducing the thermal pollution caused by the waste steam emission, protecting the environment, and improving energy utilization.

[0004] In the aforementioned prior art, the heat of the steam is transferred to the water through heat transfer, thereby reducing the temperature of the waste steam and thus reducing the thermal pollution caused by the waste steam emission. However, there are still other pollutants in the waste gas, which are discharged into the air and cause air pollution, thereby reducing the environmental friendliness. When autoclaving aerated concrete blocks, it is inconvenient to take the aerated concrete blocks out and put them in.

[0005] The existing technology has the following technical problems: the existing autoclaving device for reducing thermal pollution is not convenient for reducing waste steam pollution and is not convenient for handling autoclaved blocks; therefore, we propose an autoclaving device for reducing thermal pollution in order to solve the problems mentioned above.

[0027] 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.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: An autoclave curing device for reducing thermal pollution of aerated concrete blocks includes a tank 1. Inside the tank 1, from bottom to top, there are a placement structure 4, a moving structure 3, a guide pipe 7, a four-way pipe 8, and a heat dissipation pipe 6. A purification structure 5 is installed at the top of the outer side of the tank 1. A first sealing door 2 is rotatably connected to the inner side wall of the front side of the tank 1.

[0030] like Figures 1-5 As shown, the purification structure 5 includes a mounting shell 501, a mounting frame 502, a filter plate 503, and a second sealing door 504. The mounting shell 501 is fixedly installed on the top of the outer side of the tank body 1. The top of the heat dissipation pipe 6 is connected to the mounting shell 501. After the steam is cooled by the heat dissipation pipe 6, it enters the mounting shell 501. The mounting frame 502 is equipped with a filter plate 503. From bottom to top, the filter plates 503 are made of metal, ceramic, and composite activated carbon, respectively. The metal filter plate 503 has strong corrosion resistance, the ceramic filter plate 503 has strong compressive strength and heat resistance, and the composite activated carbon filter plate 503 can absorb harmful gases. The gas passes through the metal, ceramic, and composite activated carbon filter plates 503 in sequence, thereby purifying it. A pipe is fixedly installed on the top of the mounting shell 501 so that the purified gas can exit from the pipe.

[0031] Multiple mounting frames 502 are fixedly installed inside the left and right walls of the mounting housing 501. The filter plates 503 are all set inside the mounting frames 502. A second sealing door 504 is rotatably connected inside the front wall of the mounting housing 501. By opening the second sealing door 504, the old filter plate 503 can be directly taken out and the new filter plate 503 can be inserted into the mounting frame 502, which makes it easy to replace the filter plate 503.

[0032] like Figure 2 and Figure 4 As shown, the placement structure 4 includes a placement plate 401 and a fixing frame 402. The fixing frame 402 is fixedly installed inside the left and right walls of the tank body 1, and the placement plate 401 is slidably connected inside the fixing frame 402.

[0033] like Figure 2 , Figures 4-6 As shown, the moving structure 3 includes a motor 301, a lead screw 302, a moving block 303, an auxiliary rod 304, and a moving plate 305. A first sealing door 2 is rotatably connected to the inner side wall of the tank body 1. When the first sealing door 2 is opened, the motor 301 is started. The output end of the motor 301 is fixedly connected to the lead screw 302. The motor 301 drives the lead screw 302 to rotate. The outer side of the lead screw 302 is threadedly connected to the moving block 303. The outer side of the auxiliary rod 304 is slidably connected to the moving block 303. The inner side of the moving block 303 is fixedly connected to the moving plate 305, so that the rotating lead screw 302 drives the moving plate 305 to move towards the first sealing door 2. The moving plate 305 is fixedly connected to the placement plate 401. The moving plate 305 drives the placement plate 401 to move towards the first sealing door 2, thereby pushing the placement plate 401 out of the tank body 1.

[0034] Place the aerated concrete block on the placement plate 401. After placement, start the motor 301 in reverse. The motor 301 drives the lead screw 302 to rotate in reverse, causing the fixed frame 402 to move into the tank 1, thereby pulling the aerated concrete block into the tank 1 and pulling the placement plate 401 into the tank 1. Then close the first sealing door 2 and perform autoclaving.

[0035] Example 2: Figure 2 and Figure 4 As shown, the bottom end of the heat dissipation pipe 6 is fixedly connected to three guide pipes 7 through a four-way pipe 8. The three guide pipes 7 are located at different positions. Hot steam enters the heat dissipation pipe 6 through the three guide pipes 7, which can reduce the accumulation of steam at the bottom of the board and reduce water droplets in the aerated block, thereby affecting the quality of the aerated block.

[0036] Working principle: such as Figures 3-5 As shown, a water inlet pipe is fixedly connected to the front wall of the tank 1 at the location of the heat dissipation pipe 6. The water inlet pipe is connected to a water pump, which is connected to the water tank. The water pump draws water from the water tank into the outside of the heat dissipation pipe 6.

[0037] Open the first sealing door 2, use the moving structure 3 to place the aerated block into the tank 1. The tank 1 is fixedly connected to the air inlet pipe below the fixed frame 402. The air inlet pipe is located inside the front and rear walls of the tank 1. Connect the air inlet pipe to the steam output equipment to input steam into the tank 1. The placement plate 401 and the fixed frame 402 are both hollowed out to facilitate the steam to maintain the aerated block.

[0038] Steam enters the heat dissipation pipe 6 from the guide pipe 7 and heats the water on the outside of the heat dissipation pipe 6, thereby cooling the hot air inside the heat dissipation pipe 6. The cooled gas is discharged into the mounting frame 502 and purified by the three-layer filter plate 503. The purified gas is discharged from the pipe at the top of the mounting frame 502.

[0039] A water outlet pipe is fixedly connected to the rear wall of the tank 1 at the position of heat dissipation pipe 6. Opening the valve there will discharge the heated water. A water outlet pipe is fixedly connected to the bottom of the tank 1. Opening the valve there will discharge wastewater.

[0040] The above completes a series of operations for the autoclaved aerated concrete block steam curing device that reduces thermal pollution. Any content not described in detail in this specification is prior art known to those skilled in the art.
