Technical Field

[0001] This utility model relates to the field of backwashing technology for slurry mixing pipelines, and in particular to an energy-saving backwashing assembly device for solid waste slurry mixing. Background Technology

[0002] In the process of solid waste resource utilization, the mixing process is to mix crushed or ground solid waste particles with chemical agents to make a slurry, dilute it with water to make a liquid slurry, and then send the slurry to a high-temperature incineration kiln through a pump pipeline to be mixed with other substances to make new environmentally friendly building materials.

[0003] During the mixing and conveying of slurry, due to the complex composition of solid waste materials and their high content of solid particles and adhesion characteristics, and the long-term conveying of slurry into the solid waste slurry incineration kiln through pipelines, some pipeline components will have residual solid waste slurry in the pipeline after a period of use. If it is not cleaned for a long time, it will easily slow down the conveying efficiency of solid waste slurry, and may even block the pipeline, affecting the subsequent solid waste incineration efficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-4 The solid waste slurry energy-saving backwashing assembly includes a cement block 1 and a slurry pipe 2 connected to the solid waste slurry pool inside the cement block 1. It also includes multiple slurry conveying components 3 installed on the cement block 1 for conveying solid waste slurry. Multiple backwashing pipes 4 are provided on the slurry pipe 2. Water flow pipes 5 are fixedly connected to the multiple backwashing pipes 4. Each backwashing pipe 4 is equipped with a fifth valve 8. The slurry conveying components 3 can transport the slurry after mixing to the solid waste high-temperature incineration kiln chamber. At this time, the solid waste slurry needs to be transported to the feeding area of ​​the adjacent incineration kiln first. After preheating to a certain temperature, the solid waste material is sent into the incineration kiln for sintering and is matched with other materials to make new building materials.

[0023] Multiple backwash pipes 4 can be used to flush the slurry that has settled inside the slurry conveying assembly 3 with reverse water flow.

[0024] The slurry conveying assembly 3 includes a first extraction pipe 301, a second extraction pipe 302, and a third extraction pipe 303, which are fixedly connected to the internal mixing slurry pipeline 2.

[0025] The cement block 1 is equipped with a first pump 304, a second pump 305, and a third pump 306, which correspond to the first extraction pipe 301, the second extraction pipe 302, and the third extraction pipe 303, respectively.

[0026] The first extraction pipe 301, the second extraction pipe 302, and the third extraction pipe 303 are each equipped with a first valve 307, and the first pump 304, the second pump 305, and the third pump 306 are respectively fixedly connected to the first delivery pipe 308, the second delivery pipe 309, and the third delivery pipe 310.

[0027] Each of the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310 is equipped with a second valve 311 and a pressure sensor 312 at one end. One end of the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310 is fixedly connected to a pipe 313 leading to the high-temperature incineration chamber of solid waste. A third valve 314 is installed on the pipe 313 leading to the high-temperature incineration chamber of solid waste. The pressure sensor 312 can detect the pressure inside the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310 to determine whether there is any residual solid waste slurry in the pipe. When the value on the pressure sensor 312 is less than the preset value, it is necessary to perform a reverse flushing operation inside the three conveying pipes.

[0028] When it is necessary to transport the slurry of the internally mixed solid waste to the feeding area of ​​the adjacent high-temperature solid waste incineration kiln, the second pump 305 and the third pump 306 are turned off, the first valve 307 on the second extraction pipe 302 and the third extraction pipe 303 is turned off, and then the second valve 311 on the second conveying pipe 309 and the third conveying pipe 310 is turned off. The third valve 314 on the pipe 313 adjacent to the high-temperature solid waste incineration kiln chamber is turned on. The slurry is then drawn from the internally mixed slurry pipe 2 through the first extraction pipe 301 by starting the first pump 304. The slurry is then transported from the first conveying pipe 308 to the feeding area of ​​the adjacent high-temperature solid waste incineration kiln.

[0029] By using multiple slurry conveying components 3, if one set of conveying pipes is damaged, other conveying pipes can be used for conveying, in order to prevent the cessation of solid waste slurry conveying and production delay.

[0030] Multiple backwash pipes 4 are fixedly connected to the first pump 304, the second pump 305, and the third pump 306, respectively. An air inlet pipe 6 is fixedly connected to the first delivery pipe 308, and a fourth valve 7 is installed on the air inlet pipe 6. When cleaning the pipes conveying slurry with air, the third valve 314 is closed, each second valve 311 and the first valve 307 are opened, and the fifth valve 8 on all backwash pipes 4 is closed. Then, by connecting the air inlet pipe 6 to an external air supply facility or an air compressor, the fourth valve is opened. Gate 7: Gas is transported from the air inlet pipe 6 to the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310. Then, it passes through the first pump 304, the second pump 305, and the third pump 306, and is discharged from the mixing slurry pipeline 2 through the first extraction pipe 301, the second extraction pipe 302, and the third extraction pipe 303, respectively. This can clean the pipeline that transports the slurry by blowing air, and remove small impurities and moisture remaining after backwashing with water, thus achieving a secondary cleaning effect on the backwashing pipeline 4.

[0031] In this invention, during the backwashing operation of the solid waste material accumulated inside the pipeline, the fourth valve 7 and the third valve 314 are closed, all the second valves 311 are opened, the first valve 307 on the first extraction pipe 301 is closed, the first valves 307 on the second extraction pipe 302 and the third extraction pipe 303 are opened, the fifth valve 8 on the second pump 305 and the third pump 306 is closed, the fifth valve 8 on the first pump 304 is opened, the water flow pipe 5 is connected to an external water source, and the first pump 304 is started to draw water through the water flow pipe 5 into the first conveying pipe 308, then forms a diversion into the second conveying pipe 309 and the third conveying pipe 310, and then the water flows through the second pump 305 and the third pump 306 into the second extraction pipe 302 and the third extraction pipe 303 respectively, and is discharged from the mixing slurry pipe 2, thus cleaning the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310. Backwashing removes solid waste accumulated in the pipes without disassembling them. After backwashing, the third valve 314 is closed, each second valve 311 and the first valve 307 are opened, and the fifth valve 8 on all backwash pipes 4 is closed. Then, by connecting the air inlet pipe 6 to an external air supply facility or air compressor, the fourth valve 7 is opened, and gas is transported from the air inlet pipe 6 to the first conveying pipe 308, the second conveying pipe 309, and the third conveying pipe 310. Then, through the first pump 304, the second pump 305, and the third pump 306, the gas is discharged from the mixing slurry pipe 2 through the first extraction pipe 301, the second extraction pipe 302, and the third extraction pipe 303, respectively. This can clean the slurry conveying pipe by blowing air, removing small impurities and moisture remaining after backwashing with water, and achieving a secondary cleaning effect on the backwash pipes 4.

[0032] The above-mentioned technical design solutions can achieve timely backwashing of pipelines with some accumulated solid waste, ensuring that the solid waste slurry is transported quickly in the pipeline. This will not lead to high energy consumption in slurry transport due to some accumulated solid waste in the pipeline, resulting in good energy saving. It will also prevent the solid waste slurry from clogging the pipeline due to long-term accumulation in the pipeline, thus saving the dismantling and maintenance costs of blocked pipelines.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
