Energy-saving and environment-friendly self-flowing type coating and pesticide mixing system

Abstract

The invention belongs to the technical field of seed coating, and particularly relates to an energy-saving and environment-friendly self-flowing type coating and pesticide mixing system which comprises a pesticide mixing mechanism, a backflow mechanism and a cleaning mechanism, and the pesticide mixing mechanism comprises a water heater, a raw pesticide barrel, a surge tank, a temporary storage barrel, a weighing barrel, a stirring barrel, a working barrel and a pesticide preparation water supply tank. The upper portions of the five temporary storage barrels are connected with the corresponding raw pesticide barrels through pipelines, valves and second conveying pumps, the lower portions of the five temporary storage barrels are connected with the weighing barrel through valves and pipelines, and the lower portion of the weighing barrel is connected with the stirring barrel through valves and pipelines. The lower part of the stirring barrel is connected with the working barrel through a valve and a pipeline; through mutual cooperation of the medicine mixing mechanism, the backflow mechanism and the cleaning mechanism, the problem of medicine homogeneity can be avoided, the circulating system recycles the medicine, the medicine supply precision of the system is improved, automatic cleaning of the system is achieved, system faults are reduced, and the medicine purity is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of seed coating, and in particular relates to an energy-saving and environment-friendly self-flow coating and medicine mixing system. Background technique [0002] With the in-depth advancement of the national seed project, the seed coating rate in my country is increasing at a rate of more than 20 per year, and the demand for seed coating equipment also increases. In order to adapt to the increasingly wide variety of combinations of seed coating agents with more complex formulations, the coating machine needs to be equipped with a more flexible, stable, accurate and safe seed coating agent premixing system. At present, a coating equipment is composed of an independent seed coating agent mixing drug supply system and a coating machine, which can realize the large-scale production of seed coating. , Seed coating film uniformity and so on. The seed coating agent mixing and medicine supply system is composed ...

Problems solved by technology

[0003] In the actual production process, the state of the seed coating agent is different due to the difference in composition, and the homogeneity problem of the agent sometimes occurs when the agent is still; the temperature of the agent dilution medium should be adjusted according to different production environments, and the temperature is too low Seed coating will cause waxing phenomenon, and the seed coating agent cannot form a film and cannot be mixed evenly, which affects the efficacy of the drug; the accuracy of the dosage of the seed coating agent affects the proportion of the drug species, and the improper proportion of the drug species affects the growth and development of the seed; the seed coating agent It is a slightly toxic preparation, and the recovery of the remaining agents in the mass production process has an impact on production efficiency, the environment and personnel health. The existence of these factors affects the quality and production efficiency of seed coating, and should be paid attention to
