Inorganic fertilizer round particle one-time forming production equipment

Abstract

The invention discloses one-step forming production equipment for round inorganic fertilizer particles. The one-step forming production equipment comprises a granulation main body, a thermal expansion and cold contraction oscillation type deslagging mechanism, a three-dimensional surrounding type spheroidizing mechanism, a stirring type feeding device and an oscillation type discharging device. The invention belongs to the technical field of one-time forming production of round inorganic fertilizer particles, and particularly relates to one-time forming production equipment for round inorganic fertilizer particles. On the basis of a mechanical system replacement and reverse action principle, a thermal expansion and cold contraction oscillation type slag removal mechanism is creatively provided, when groove residues are cleaned, through mutual cooperation of a cutting type cold and hot field alternating type filling mechanism and a reverse action type self-service oscillation mechanism, the residues are separated from the inner wall of a groove after thermal expansion and cold contraction in the groove, and the groove residues are removed from the inner wall of the groove. In addition, the knocking particle balls knock the outer walls of the grooves, so that residues in the grooves of the extrusion roller are effectively cleaned, and the plumpness of the chemical fertilizer particles is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of one-time molding production of inorganic fat round particles, in particular to a one-time molding production equipment of inorganic fat round particles. Background technique [0002] Chemical fertilizers refer to fertilizers manufactured or mined by chemical methods and processed into fertilizers, also known as inorganic fertilizers, including nitrogen fertilizers, phosphate fertilizers, potash fertilizers, micro-fertilizers, and compound fertilizers. The existing granulation technology has the following shortcomings: the fertilizer granulator is often granulated by the extrusion method, and after granulation, it is transferred to the rounder for rounding treatment, which is time-consuming and laborious, and the production process is cumbersome. When the particles are rounded, the circular polishing machine will produce dust flying, which seriously affects the working environment and the health of the wor...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a kind of one-time molding production equipment of inorganic fertilizer round particles. In order to solve the problem that some residues will be left behind in the granulation groove of the existing granulator after a long time, it is not only difficult to To clean up and affect the shape of round particle fertilizers, this invention is based on the principle of mechanical system substitution and reverse action, and creatively proposes a thermal expansion and contraction vibration type slag removal mechanism. With the mutual cooperation of the type filling mechanism and the reverse-acting self-service oscillating mechanism, the residue breaks away from the inner wall of the groove after thermal expansion and contraction in the groove, and the knocking particle balls are knocked on the outer wall of the groove, which not only effectively cleans the The residue in the groove of the squeeze roller also ensures the fullness of the fertilizer particles; at the same time, in order to further improve the practicability and scalability, the present invention creatively proposes a three-dimensional surround-type throwing mechanism based on the principle of curved surface and nesting. Through the mutual cooperation of the multi-dimensional space movement mechanism and the heavy ball closing mechanism, the throwing of fertilizer particles can be more three-dimensional and round, and at the same time avoid the flying of dust, etc.; in order to further simplify the structure, the present invention is based on the principle of self-service, without any driving equipment In the case of intervention, only through ingenious design, the conversion of wind energy and kinetic energy is realized, and the drive of the rotating tube and the turntable is realized.
