Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and more specifically, to a reaction vessel for fertilizer production. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers. The fertilizer production process requires mixing and reacting the fertilizer raw materials in a reaction vessel.

[0003] A search revealed that utility model patent CN220657516U discloses a reaction vessel for the production of water-soluble fertilizers. The vessel includes a vessel body, a feed pipe on one side of the top of the vessel body, a U-shaped support frame at the top of the vessel body, support legs at the bottom of the vessel body, a discharge pipe in the middle of the bottom of the vessel body, a steam inlet on one side of the vessel body, a sealed bearing in the middle of the top of the vessel body, a support plate at the top of one side of the vessel body, a flushing assembly at the top of the support plate, and a stirring assembly inside the vessel body. This reaction vessel, through the flushing assembly, allows water to be added to a storage tank by opening a water valve. Then, a water pump is started to draw water from the storage tank through a first connecting pipe and introduce it into a water pipe through a second connecting pipe. The water is then sprayed from a nozzle onto the inner wall of the vessel body to flush the device, reducing the labor costs associated with cleaning the equipment. However, the above patents still have the following shortcomings: residual material will also adhere to the nozzles, water pipes and stirring components, making it inconvenient to wash them. In addition, the nozzles are in a fixed position and can only wash the inner wall of the reactor in a specific direction, which is not very practical. Therefore, we have proposed a reaction vessel for fertilizer production. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reaction vessel for fertilizer production.
