Description

Technical Field

[0001] The utility model relates to a fertilizer production device, in particular to an automatic batching device for compound fertilizer production. Background Art

[0002] When producing compound fertilizer, various elements need to be mixed together, including high content of nitrogen, phosphorus and potassium elements, as well as low content of synergists. Since the content of the two elements is too different, in the traditional large-scale production of compound fertilizer, various main ingredients are generally weighed continuously by a batching device, dropped into a mixing conveyor belt for preliminary mixing, and then transported by the mixing conveyor belt into a stirring system for uniform mixing. The synergist is added in an amount calculated based on the mixing amount of the stirring system at one time, and is directly added to the stirring system after manual weighing.

[0003] The existing main material batching device is to set a weighing bin under the silo, first put the material in the silo into the weighing bin for weighing, and when the set weight is reached, the silo is closed and the weighing bin is opened, and the material is sent to the mixing conveyor belt for weighing. Through the cyclic opening and closing of the two, the continuous weighing of the main material is realized. This structure has the following main disadvantages: (1) The weighing bin needs to reach the set weight before it can be opened, and there is a time interval in between, which has poor continuity; (2) When discharging the material, the silo and the weighing bin need to cooperate well, and the transmission of the mixing conveyor belt also needs to cooperate well with the interval opening of the weighing bin, which makes the control more complicated.
