Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical fertilizer processing, specifically to a high tower chemical fertilizer production mixing heating device with waste heat recovery function. BACKGROUND

[0002] Chemical fertilizer processing refers to the process of processing raw materials into chemical fertilizers through chemical or physical methods. Chemical fertilizers, referred to as chemical fertilizers, are fertilizers containing one or more nutrients required for crop growth, which usually include nitrogen, phosphorus, potassium, etc. The specific process of chemical fertilizer processing may involve ore mining, processing, chemical reaction, and subsequent steps such as granulation and packaging.

[0003] The existing patent (publication number: CN220214535U) discloses a chemical fertilizer production mixer, which includes a mixing container and a top cover installed on the top of the mixing container. The top of the top cover is provided with a driving motor, and the power output end of the driving motor is connected with a stand column. A plurality of groups of spiral blades are installed on the stand column, and the adjacent two groups of spiral blades are connected end to end. The plurality of groups of spiral blades are located in the mixing container. The top cover includes a cover body and a receiving tray located below the cover body. The receiving tray is provided with a baffle, and the middle part of the baffle is provided with a through hole. The stand column is inserted into the through hole. An opening is formed in one side of the baffle. When the chemical fertilizer raw materials need to be refined, the staff can guide the chemical fertilizer raw materials to the top of the mixer. The rotating refining mechanism can drive the chemical fertilizer raw materials to rotate. During the rotation process, the chemical fertilizer raw materials can be refined and discharged through the internal discharge port. One power assembly can achieve the purpose of stirring and raw material refinement.
