Technical Field
[0001] The utility model belongs to the technical field of waste fly ash treatment, and particularly relates to a fly ash pre-stirring device for a waste incineration power plant. Background Art
[0002] At present, with the rapid development of the economic society and the steady improvement of residents' living standards, the output of domestic waste (especially urban domestic waste) has increased sharply. The simple landfill method of waste can no longer meet the waste treatment needs. Waste incineration power generation has developed rapidly due to its advantages of "harmlessness, reduction, and resource utilization". Therefore, most current waste treatment plants use waste incinerators to incinerate waste. A large amount of fly ash is generated when the waste incinerator incinerates waste. Since the fly ash contains a large amount of heavy metals and highly toxic organic substances, a bag filter is needed to collect the fly ash, and the fly ash is added to a stirring device filled with chemical agents. The stirring device stirs and mixes the chemical agents and the fly ash to ensure that the fly ash reacts fully. After a period of reaction, a material with low solubility, low toxicity, and low mobility is prepared.
[0003] In the prior art, for the fly ash stirring device applied in a waste incineration power plant, it generally includes a tank body, a motor, a stirring shaft, blades, an elbow pipe, a scraper, etc. Its structure is compact, which can improve the discharge speed of the material after reaction, improve the mixing efficiency, and is easy to operate. Considering that during the use of the fly ash stirring device, liquid chemical agents will be added to the tank body, the above equipment pre-injects the liquid material into the tank body, and then directly conveys the fly ash material to below the liquid level. The defects are as follows: the material input into the tank body is likely to form lumps when contacting the liquid material, affecting the working process. Moreover, for the elbow pipe device for conveying fly ash, the liquid material will enter the elbow pipe, which will not only affect the discharge process of the material, but also the liquid material is easy to flow back into the elbow pipe, bringing troubles to the subsequent production and processing process and unable to effectively meet the use requirements. For this reason, we provide a waste incineration power plant fly ash pre-stirring device with reasonable design, simple structure, convenient processing, and can effectively improve the rationality of the equipment components, realizing the full mixing between solid materials and liquid materials, especially completing the blending between the two materials, improving the mixing effect, and effectively meeting the use requirements.

Below the tank body 1, there is a discharge port 1c. The establishment of the above-mentioned equipment components are all existing mature and commonly used technical means, and the specific installation methods, etc. will not be elaborated here. To ensure the effective realization of the stirring work inside the tank body 1, a driving component 2 is arranged above the tank body 1, and its function is to provide driving power for the stirring component to ensure the work process. To achieve the full mixing of the materials inside the tank body 1 and improve the work process, a stirring component is arranged below the driving component 2. Among them, two sets of stirring components are provided.
