Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a solidification device for fly ash from municipal solid waste incineration. Background Technology

[0002] The fly ash solidification device for municipal solid waste incineration is mainly used to treat the fly ash produced after waste incineration. Its working principle is to add a solidifying agent and mix it with the fly ash, so that the heavy metals and harmful substances in the fly ash are fixed in the solidified body. Common solidifying agents include cement and lime. The device generally includes a feeding system, a mixing system, and a curing system. The feeding system can precisely control the amount of fly ash and solidifying agent fed in, ensuring that they are added in a certain proportion. The mixing system is the core part. Through strong stirring, the fly ash and solidifying agent are fully and evenly mixed, just like mixing flour and other ingredients when making a cake, so that the solidification reaction can proceed more effectively. The curing system provides a suitable environment for the solidified product, so that its strength and other properties meet the requirements. For example, controlling temperature and humidity helps to form a stable solidified body and reduce the leaching of harmful substances.

[0003] A search revealed Chinese Patent Publication No. CN210477067U, which discloses a solidification device for municipal solid waste incineration fly ash. This device includes a tank with a mixing mechanism, a spraying mechanism, and a briquetting mechanism. The mixing mechanism comprises a first feed pipe, a second feed pipe, a motor, a rotating shaft, multiple mixing blades, a discharge pipe, and valves. The first and second feed pipes are fixedly installed on the top of the tank, the motor is fixedly installed on the top of the tank, and the rotating shaft is rotatably installed inside the tank, with its top end fixedly connected to the motor's output shaft. This device can thoroughly mix fly ash, cement, and solidifying agent, improving the solidification effect. It also scrapes off the mixture adhering to the inner wall of the tank and briquettes it, facilitating subsequent processing. However, while this device achieves the effect of scraping off the mixture adhering to the inner wall of the tank and briquetting it, it cannot solve the problem of combining preheating and mixing and automatically conveying the mixture to the solidification tank.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the fly ash enters the preheater through a conveyor cylinder and slides down the slope. At the same time, the heating pipe heats the fly ash, and the heat is transferred to the inside of the fly ash through the inside of the preheater. Meanwhile, the protective net blocks the fly ash from entering the other side of the protective net. The heated fly ash then enters the inside of the protective cylinder through the circular hole. At this time, motor one is started, and motor one drives the conveyor rod to rotate. Then the conveyor rod rotates and pushes the fly ash to the other side, realizing the integration of stirring and heating, and the direct transfer of the heated fly ash to the inside of the curing reaction tank.

[0030] 2. In this utility model, after prolonged use, the inside of the mixing tank becomes filled with dust. At this time, the electric push rod is activated, which will drive the connecting column downward. Then, the connecting column drives the brush ring downward. At this time, the brush ring drives the sliding block downward. The sliding block moves along the fixed column and squeezes the spring, thus cleaning the inside of the mixing tank and preventing it from becoming clogged. Attached Figure Description

[0045] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The top left side of the mixing tank 1 is connected to the feed inlet 19, and the top right side of the mixing tank 1 is connected to the feed inlet 20, which can be used for feeding.

Furthermore, to further optimize the mixing process, another feed inlet 20 is also provided on the top right side of the mixing tank 1.

[0047] Working principle: First, the fly ash to be mixed is added through the feed inlet 20 and the support leg 21. Then, the motor 16 drives the rotating rod 17 and the stirring blade 18 to stir it. Then, it enters the preheater 4 through the conveyor cylinder 3 and slides down the slope 8. At the same time, the heating tube 10 heats it. The heat is transferred to the inside of the fly ash through the inside of the preheater 4. Meanwhile, the protective net 9 blocks the fly ash from entering the other side of the protective net 9. The heated fly ash enters the inside of the protective cylinder 5 through the circular hole 12. Then, the motor 6 is started. The motor 6 drives the conveyor rod 7 to rotate. Then, the conveyor rod 7 rotates and pushes the fly ash to the other side. Then, the fly ash falls into the solidification reaction tank 14, where solidification can be carried out. This realizes the function of integrating stirring and heating, and the heated fly ash can be directly transferred to the inside of the solidification reaction tank 14.

[0048] After prolonged use, the inside of the mixing tank 1 becomes filled with dust. Activating the electric actuator 201 will cause the connecting column 202 to move downwards, which in turn pushes the brush ring 203 downwards. The brush ring 203 then moves the sliding block 204 downwards, along with the fixed column 205, simultaneously compressing the spring 206. When the brush ring 203 reaches the bottom, the electric actuator 201 retracts, and the spring 206 returns to its original position, causing the sliding block 204 and brush ring 203 to move upwards until they are reset. This effectively cleans the inside of the mixing tank 1 and prevents blockage.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
