Compound fertilizer grain volume control system

Abstract

The invention discloses a compound fertilizer grain volume control system comprising a feeding mechanism, a mixing trough, a rotary spray head, a slurry conduit, a rotary spray head motor and a control system. Compound fertilizer slurry in the mixing trough enters the rotary spray head driven by the rotary spray head motor for granulation through the slurry conduit. The control system comprises a temperature sensor device, a temperature sensor processing device, a signal amplifying device, a rotating speed controller and a feeding ratio controller, wherein the temperature sensor device outputs the detected temperature value of the compound fertilizer slurry in a mode of detecting current; the temperature sensor processing device receives the detecting current and forms a detecting current signal; and a control signal is formed through the signal amplifying device and output to the rotating speed controller and the feeding ratio controller so as to control the rotating speed of the spray head motor and the feeding ratio of the compound fertilizer slurry. The invention provides a compound fertilizer production system which can produce fertilizers with uniform volume of grains and is beneficial to improving the fertilization effect.

Description

technical field [0001] The invention relates to a compound fertilizer granule volume production system, in particular to a compound fertilizer granule volume control system. Background technique [0002] As the world's population continues to grow, the arable land is decreasing day by day. It is no exaggeration to say that the food crisis is threatening human beings. Therefore, increasing production and income has become an important topic of modern agricultural research. Therefore, modern agricultural production pays attention to efficiency, and chemical fertilizers play a very important role in improving the efficiency of agricultural production. [0003] At present, there are various chemical fertilizers on the market, mainly simple chemical fertilizers containing only nitrogen, phosphorus, and potassium, and compound chemical fertilizers containing multiple elements. The production methods of compound fertilizers generally include aggregate method, slurry method, extrus...

Problems solved by technology

[0004] However, the actual production experience is: no matter whether the rotary differential nozzle granulator, fixed nozzle granulator and vibrating nozzle granulator are used to produce granulation or other granulators, due to the compound fertilizer slurry in the mixing tank The temperature or pressure cannot be kept consistent all the time, or the nozzle speed of the granulator is uneven, resulting in the production of compound fertilizer particles that cannot always control the size of the particle volume well.

Compound fertilizers with uneven particle size firstly cause low market appearance, and more importantly, the dissolution rate is inconsistent, causing small particles to dissolve too quickly and large particles to be difficult to dissolve

Therefore, it is impossible to allow crops to absorb the predetermined amount of compound fertilizer at the right time, so that the expected fertilization purpose cannot be achieved, and the effect of fertilization is reduced.
