Spray drying equipment and spray drying method for chemical fertilizer production

Abstract

The invention discloses spray drying equipment and spray drying method for chemical fertilizer production, and belongs to the technical field of chemical fertilizer processing equipment. The spray drying equipment comprises a drying tank, a bearing is clamped to the side surface of the drying tank, and a driving shaft is sleeved with the bearing. According to the spray drying equipment and spray drying method for chemical fertilizer production, through mutual cooperation of the designed structures such as a flow dividing base, a flow dividing cover, a motor, a driving shaft, a heat dividing pump, fan blades, a driving rod, a pull rod, a hydraulic cylinder, a pin shaft, a clamping base, a supporting spring and a connecting sleeve, the multi-stage drying effect can be achieved, uniform and thorough drying of fertilizer is achieved, the fertilizer drying time is shortened, the storage time of chemical fertilizer is prolonged, the multi-stage drying effect can be effectively achieved, thedried chemical fertilizer can be directly guided toward a discharging pipe to be discharged after repeated circulating and reciprocating flow changing work, in the process, new chemical fertilizer tobe dried can be directly injected into the drying tank, and the chemical fertilizer drying efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer processing equipment, and in particular relates to a spray drying equipment and drying method for chemical fertilizer production. Background technique [0002] Chemical fertilizers, referred to as chemical fertilizers, are fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements needed for the growth of crops, also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. , they have the following common characteristics: simple ingredients, high nutrient content, fast fertilizer efficiency, strong fertilizer, some fertilizers have acid-base reaction, generally do not contain organic matter, have no effect of improving soil and fertilizing, there are many types of chemical fertilizers, The properties and methods of application vary widely.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve some shortcomings in the process of using the current drying equipment for chemical fertilizer production, when performing operations, mostly the hot air after drying is directly sprayed into the drying vessel, and a stirring mechanism is used to cooperate with it. To achieve the drying of chemical fertilizers, due to the large amount of chemical fertilizers injected, the chemical fertilizers will not be able to move effectively in the drying container, causing the accumulation of chemical fertilizers, and the inside of the chemical fertilizers cannot be completely dried. The dried chemical fertilizers are mixed, mostly after the dried chemical fertilizers are removed and then the dried chemical fertilizers are put in, which is easy to reduce the working efficiency of the equipment, and in the process, the equipment is still in the working state, and it is impossible to achieve energy saving and environmental protection. problem, and proposed a spray drying equipment and drying method for fertilizer production
