Technical Field

The invention belongs to the technical field of insecticidal pesticides, and particularly relates to an insecticide and a preparation method thereof.

Background

The pesticides can be used for killing insects, fungi and other organisms harmful to the growth of crops, and the first pesticides used are DDT, Liuliu, and the like, which can largely kill pests. But they are good in stability, can exist in the environment for a long time, and are continuously accumulated in animals, plants and human bodies, so that they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were substituted for the original pesticides. Because of the great toxicity and great harm to human and livestock, in recent years, a batch of high-efficiency and low-toxicity pesticides appear, and have specificity, namely hormone pesticides, which are good for plants and cause potential safety hazards when being eaten by mistake.

In the application number of CN110477046A, a Chinese traditional medicine insecticide and its preparation method, the materials of rangooncreeper fruit, radix euphorbiae lantu and areca seed are used, the rangooncreeper fruit contains potassium rangooncreeper fruit, betulinic acid and oleic acid, etc., and has paralysis effect on pests; the radix euphorbiae lantu contains flavonoid compounds, and can obviously inhibit the respiration of pests; the areca nut contains rich arecoline, can anaesthetize the nervous system of pests, is safe, efficient and environment-friendly, is not easy to produce drug resistance, provides a material guarantee for developing green agriculture and organic agriculture, but has the following defects in the scheme:

1. the pesticide has poor systemic property of plant roots, low mammalian toxicity, high efficiency, broad spectrum, poor environmental compatibility and the like, and especially has no good control effect on homoptera aphids and hemiptera planthoppers.

2. The toxicity of the current pesticide is generally high, and modern agriculture production green products and pollution-free products are not allowed to be used, but the toxicity is light, and the effect is little for some insects with high drug resistance.

3. Subjective standards are more on the one hand in the manufacturing process, large-batch production is difficult to realize during production, and meanwhile, raw materials are not effectively cut before cooking, so that the cooking time is longer, the efficiency is lower, and finally, the crushed particles are larger, so that effective components are difficult to effectively release.

4. Meanwhile, various plant raw materials are mixed, the smell is heavy, and some people can reject the pungent taste and even have adverse reactions and other problems.

Aiming at the technical scheme, the method is remarkably optimized and improved on the basis of the process steps of the scheme, adopts special raw materials, can improve the production efficiency, shorten the production time, reduce the process conditions and the cost and enhance the insecticidal effect.

Therefore, the company designs and develops an insecticide and a preparation method thereof, and solves the technical problems.

The outer end of the poking plate 6 is fixedly connected with a filter screen 62; the filter screen 62 is made of flexible stainless steel metal material, and the inner end part of the filter screen 62 is fixedly connected with packing rubber 63; an installation groove 64 is formed in the packaging rubber 63; the mounting groove 64 is filled with non-Newtonian fluid; when the poking plate 6 is used for swinging up the clarified solution to the lower surface of the evaporating plate 31, the outer end of the poking plate 6 is fixedly connected with the filter screen 62, the filter screen 62 is made of flexible stainless steel metal material, so that the clarified solution can be filtered by the filter screen 62 and sprayed to the lower surface of the evaporating plate 31 when being swung up, further filtration of the clarified solution is realized in the process of promoting fusion by stirring, impurities such as dust and the like are prevented from being adsorbed when the clarified solution is transferred and poured into the liquid inlet groove 2 to cause evaporation, so that the pesticide blocks a spray opening of a bottle mouth after packaging is completed, inconvenience in use is caused, meanwhile, the inner end part of the filter screen 62 is fixedly connected with packaging rubber 63, an installation groove 64 is formed in the packaging rubber 63, and non-Newtonian fluid is filled in the installation groove 64, so that the non-Newtonian fluid is solidified due to large swinging force when the rotating wheel 5 rotates at, thereby improved its centrifugal gravity greatly when the running wheel 5 rotates, that is to say that impurity such as the dust that gets filtered is by the compaction to make impurity be difficult for droing, further ensure that the clarification solution of evaporating plate 31 lower surface is in the no impurity state.

The specific working process is as follows:

when the clarified solution needs to be evaporated, the heat-insulating ring 41 can be heated to enable the temperature in the evaporation cavity 4 to be higher than the outer side of the evaporator, and the clarified solution is slowly poured into the liquid inlet groove 2 and then enters the evaporation cavity 4 through the liquid inlet pipe 3, at the moment, the motor is started to drive the rotating wheel 5 to rotate, namely, the rotating wheel 5 starts to drive the stirring plate 6 to stir the clarified solution, and the clarified solution is stirred up to the evaporation plate 31 through the collecting plate 7 at the outer end of the rotating wheel, at the moment, because the temperature of the evaporation plate 31 is higher than that of the heat-insulating ring 41, the evaporation plate 31 can heat and evaporate the clarified solution on the lower surface of the evaporation plate, and finally the clarified solution enters the cavity above the evaporation plate 31 through the evaporation plate 31 and is led out through the pores in the right side wall of the main frame body 1, in the process, when the evaporation plate 31 evaporates the clarified solution on the lower surface of the evaporation plate, the cavity above the evaporation cavity 4 can, thereby assisting the clarified solution on the lower surface of the evaporating plate 31, the heat preservation ring 41 can preheat the clarified solution, the temperature of the clarified solution is controlled at the critical point of easy evaporation by matching with the rotating wheel 5 under the condition that the clarified solution is not evaporated, thereby the clarified solution is evaporated more rapidly, the production efficiency is greatly improved, when the poking plate 6 swings the clarified solution to the lower surface of the evaporating plate 31, because the outer end of the poking plate 6 is fixedly connected with the filter screen 62, the filter screen 62 is made of flexible stainless steel metal material, the clarified solution can be filtered by the filter screen 62 and then sprayed to the lower surface of the evaporating plate 31 when being swung, further filtering the clarified solution in the process of promoting fusion by stirring is realized, the clarified solution is prevented from adsorbing impurities such as dust and the like to cause the evaporated gas to carry impurities when being transferred and poured into the liquid inlet tank 2, thereby causing the injection port of the blockage of the insecticide after the packaging is completed, cause the use inconvenient, end fixedly connected with packing rubber 63 because of filter screen 62 simultaneously, mounting groove 64 has been seted up to packing rubber 63's inside, the mounting groove 64 intussuseption is filled with non-newton fluid, so can make non-newton fluid receive great power of getting rid of and take place the solidification when rotating wheel 5 high-speed rotation, thereby improved its centrifugal gravity greatly when rotating wheel 5 and rotating, even if impurity such as filtered dust is compacted, thereby make impurity be difficult for droing, further ensure that the clarification solution of evaporating plate 31 lower surface is in the no impurity state.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
