Description

Technical Field

[0001] The utility model relates to the technical field of pesticide preparation production process equipment, in particular to a process system for producing milk powder type pesticides. Background Art

[0002] Pesticide technical materials, except for water-soluble and volatile technical materials, generally cannot be applied directly due to lack of dispersibility. They must be prepared with appropriate pesticide adjuvants according to the properties, usage methods, and control targets of the technical materials, and processed through certain processes to form suitable forms, called pesticide preparations, to increase their dispersibility. The purpose of pesticide preparations is to facilitate application and to make them conform to the three principles of "safety, economy, and effectiveness."

[0003] The basic dosage forms of traditional pesticide preparations are powder, wettable powder, emulsifiable concentrate and granules. With the development of technology and the needs of the times, a large number of new environmentally friendly pesticide dosage forms have evolved from these four basic dosage forms, and emulsifiable powder is one of them. Emulsifiable powder is a new dosage form developed on the basis of wettable powder and emulsifiable concentrate. It combines the advantages of both wettable powder and emulsifiable concentrate and has its own unique characteristics. For example, emulsifiable powder can use no or less organic solvents, saving a lot of organic solvents, avoiding the harm of organic solvents to people and the environment during production and use, and has good safety; emulsifiable powder has good fluidity, no adhesion, no agglomeration, and is easy to store and transport; emulsifiable powder has high biological activity, and the efficacy is equivalent to that of the same dose of emulsifiable concentrate; emulsifiable powder has good blending properties with the nutrient element fertilizers required by various crops, etc. The national standard "Names and Codes of Pesticide Formulations" (GB / T 19378-2017) defines emulsion powder (EP) as a powdered preparation in which the active ingredient is dissolved in an organic solvent, encapsulated in a soluble or insoluble inert ingredient, and dispersed in water to form an oil-in-water emulsion.

[0004] Since emulsions are developed on the basis of wettable powders and emulsifiable concentrates, the current processing technology of emulsions is basically an intermittent and segmented processing technology formed by combining the processing technology of emulsifiable concentrates and wettable powders. The processing method is: firstly, the active ingredients of the emulsions are dissolved or diluted in a suitable organic solvent, a surfactant is added and mixed, and then the emulsions are evenly sprayed onto a certain amount of carriers through a sprayer and mixed evenly, and the desired emulsion pesticide can be obtained. Figure 1As shown, the oil-based raw materials (pesticide original medicine, emulsifier, organic solvent, etc.) are prepared into oil-based in the liquid agent workshop using the oil-based preparation kettle of the processing equipment of the emulsifiable concentrate, while the fillers and auxiliary materials are prepared into carriers for adsorbing the oil-based in the powder agent workshop using the mixer and pulverizer of the processing equipment of the wettable powder, and then the oil-based is transferred to the powder agent workshop, and the oil-based is evenly sprayed on the carrier using a sprayer to mix evenly to obtain the required emulsifiable powder. Due to the high viscosity and poor fluidity of the oil-based, especially the oil-based prepared by the melting method, the oil-based needs to be kept warm when it is transferred from the liquid agent workshop to the mixer of the powder agent workshop (according to the melting temperature of the oil-based, it is generally required to be above 80°C) to ensure the realization of the oil-based spray. Therefore, the existing emulsifiable powder processing technology has high requirements for equipment, and the workers are inconvenient to operate. The high-temperature transfer of the oil-based not only poses a safety hazard to the workers' operation, but also the oil-based transfer leads to the inability to realize the continuous production of the emulsifiable powder, and the product production efficiency is low. In addition, in the current processing technology, the oil-based and the carrier have only one mixing process, which is easy to mix unevenly and the product quality qualification rate is low. Utility Model Content

[0005] In view of this, the utility model provides a process system for producing milk powder formulation pesticides, which requires simple and easy-to-deploy equipment, has low requirements for equipment and technology, is convenient for workers to operate, and improves the quality qualification rate and production efficiency of milk powder formulation products.

[0006] To achieve the above objectives, the utility model provides a process system for producing milk powder pesticides, which includes an emulsifying stirring device, a first mixer, a pulverizer and a second mixer connected in sequence, and the finished product prepared by the emulsifying stirring device is in a solid state.

[0007] Specifically, in some embodiments of the utility model, the emulsifying stirring device includes a frame, a pot body and a stirring assembly, the pot body is rotatably mounted on the frame, the outer cover of the pot body is provided with a jacket, the stirring assembly includes a stirring motor, a stirring shaft connected to the output shaft of the stirring motor and an agitator arranged on the stirring shaft, and the stirring shaft and the agitator can be placed in the pot body.

[0008] Preferably, the agitator includes a stirring rod fixed on a stirring shaft and several wall-adhering shovels arranged on the stirring rod, and the shape of the stirring rod matches the cross-sectional shape of the pot body. The structure of the agitator provided by the utility model is conducive to the emulsification of the oil base and the adsorption of the adsorbent. Further, the agitator also includes a stirring cross bar, and the stirring cross bar connects the two ends of the stirring rod to strengthen and stabilize the stirring rod. Further. Rotating shafts are fixed on both sides of the pot body, and the rotating shafts are installed on the frame and connected to the rotating wheel, and the turning of the pot body is achieved by rotating the rotating wheel. Further, heat transfer oil is arranged in the jacket, and the emulsification stirring device adopts heat transfer oil heating, and there is no need to connect to the steam pipeline. It can be arranged on the same operating platform in the same workshop with other powder processing equipment, which greatly improves the convenience of production operation. Of course, the heating method of the emulsification stirring device can also choose gas heating, steam heating, electric heating and other heating methods.

[0009] The utility model is based on the consideration that the oil base needs to be kept warm during the transfer process, and is designed to directly adsorb the oil base in the emulsification stirring device to form a solid base, which is prepared as a solid, thereby avoiding the transfer of the oil base, avoiding the need for heat preservation of the oil base during the transfer process, reducing the requirements for equipment and technology, greatly improving the feasibility of operation, and the oil base can be mixed with the filler for a second time after being prepared as a solid, thereby improving the mixing uniformity of the raw materials. However, the discharge pipe orifice of the existing emulsifiable oil-based configuration kettle is thin, and the output of solid materials is prone to blockage. Therefore, the utility model refers to the sandwich pot used in the food or chemical industry to design an emulsifiable stirring device to replace the emulsifiable oil-based configuration kettle for oil-based configuration and solidification. The emulsified stirring device provided by the utility model has the functions of heating and stirring, can meet the configuration requirements of the oil base, and its discharge method is to turn over the discharge, and there is no problem of discharge blockage.
