Automatic adding system for anti-blocking agent for compound fertilizer

Abstract

The invention discloses an automatic adding system for an anti-blocking agent for a compound fertilizer, wherein an oil storage tank is connected to a heating tank through a transfer pipeline, the bottom part of the heating tank is provided with an oil weighing sensor, the lower part of the heating tank is communicated with a hopper of a conveyer through an oil transfer pipe, a metering pump is arranged on the oil transfer pipe, the metering pump is driven by a variable frequency motor, the outlet of the conveyer is arranged in an enveloping machine, the conveyer is driven by the variable frequency motor, a fertilizer metering conveyer belt is provided with a fertilizer weighing sensor, a fertilizer conveying tank is arranged below an outlet end of the fertilizer metering conveyer belt, an outlet of the fertilizer conveying tank is arranged in the enveloping machine, and a PLC (programmable logic controller) is electrically connected with a touch screen; the fertilizer weighing sensor, the oil weighing sensor, the metering pump variable frequency motor and the conveyer variable frequency motor are electrically connected to the PLC, respectively. The automatic adding system is simple in structure and convenient to operate, the added amount of the anti-blocking agent is exact, the labor intensity of the workers is reduced, the production cost is reduced, and the anti-blocking property of the compound fertilizer is effectively improved.

Description

technical field [0001] The invention belongs to the field of compound fertilizer production, in particular to an automatic adding system of an anti-caking agent in the compound fertilizer production process. Background technique [0002] At present, when many compound fertilizer companies add anti-caking agents to compound fertilizers, the production process is intermittent, and multiple steps are manually operated, which leads to operational errors by different personnel and inaccurate ingredients. Some uncontrollable human factors cause uneven coating of anti-caking agent and inaccurate dosage. Through investigation and experiments, it is found that the amount of anti-caking agent directly affects the caking property of compound fertilizer. The traditional way of adding anti-caking agent is to predict the amount of anti-caking agent according to the amount of compound fertilizer, which is manually adjusted. The relative amount of anti-caking agent added by this method is ...

AI Technical Summary

Problems solved by technology

The relative amount of anti-caking agent added by this method is relatively stable, but if the output of compound fertilizer fluctuates, it will cause problems such as increased production costs and uneven addition amount.

The process of other addition methods is complicated, which greatly increases the production cost
