Chemical fertilizer mixing granulator

Abstract

The invention belongs to the field of chemical fertilizer production, and relates to a chemical fertilizer mixing granulator which comprises a shell, supporting columns are fixedly arranged on the front portion, the rear portion, the left portion and the right portion of the lower side of the shell respectively, a discharging port is fixedly formed in the lower side of the shell, a feeding port is fixedly formed in the upper side of the shell, and a piston is slidably arranged in the feeding port; a piston is arranged in the shell, an upper cover is fixedly arranged on the upper side of the piston, a stirring cavity is formed in the upper side in the shell, an extrusion cavity is formed in the middle in the shell, a drying cavity is formed in the lower side in the shell, and a stirring device is arranged in the stirring cavity. Chemical fertilizer raw materials can be fully mixed and stirred, water is sprayed out through a water flow channel in a stirring rod, so that the raw materials can be fully mixed with the water, in addition, the raw materials can be rapidly extruded and granulated through an extrusion device, then granules are dried through heat generated by a motor, energy is saved, and the production efficiency is improved. Energy waste is avoided, and meanwhile the motor can be cooled.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer production, in particular to a fertilizer mixing and granulating machine. Background technique [0002] As we all know, chemical fertilizers, referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods containing 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. Fertilization can not only improve soil fertility, but also an important measure to increase crop yield per unit area. Fertilizer is the most basic and most important material input in agricultural production. At present, fertilizer granule manufacturing equipment has become one of the indispensable equipment in fertilizer processing plants. With the continuous development of chemical fertilizer granule manufacturing equipment, che...

Problems solved by technology

Fertilizer is the most basic and important material input in agricultural production. At present, fertilizer granule manufacturing equipment has become one of the indispensable equipment in fertilizer processing plants. With the continuous development of chemical fertilizer granule manufacturing equipment, chemical fertilizer granule manufacturing equipment has unique advantages. It has been widely used, but there are still some problems in some fertilizer granule manufacturing equipment,

[0003] 1. The mixing and granulation of chemical fertilizer raw materials are generally two equipments. After the mixing is completed, they must be transported into the granulator for granulation, which takes a long time and is inefficient;

[0004] 2. It is prone to insufficient stirring when stirring, and at the same time, the effect of mixing and stirring the agglomerated fertilizer raw materials is not sufficient;

[0005] 3. The existing fertilizer production equipment occupies a large area and has low production efficiency
