## Background
FIELD OF THE INVENTION
The present invention relates to a method for manufacturing a natural pesticide or bactericide and a water quenching device thereof.
BACKGROUND OF THE INVENTION
A pesticide is a substance used for killing pets, which is often applied to agriculture, medicine, industry and home environment. In general, pesticides can be systemic or contact. The systemic pesticide is in corporation with plants. When pests eat plants, they also absorb pesticides. The contact pesticide is absorbed directly when pests are in contact with plants.
As to the hazards of pests to the growth and storage of crops, the crop yield may decrease greatly. As a result, the cost is increased to consumers. In order to achieve a high efficiency of crop productions, it is quite important for a pest control. Most pesticides are made of chemical materials. When the pesticide is applied to plants, it will permeate into the soil and into the plants from the roots to kill pests through the neurotoxin of the pesticide. However, most pests may be resistance to pesticides after a period of time. Thus, it is necessary to increase the dosage of the pesticide for plants. This not only causes soil acidification but also make the plants remain chemicals to influence the human health.

FIG. 3 is a schematic view of a water quenching device for manufacturing a natural pesticide of the present invention. The water quenching device is used to perform the aforesaid method. The water quenching device comprises a first water quenching and heating area 10, a first condenser 20, and at least one second water quenching and heating area 30.
The first water quenching and heating area 10 is configured to input the carbonized paddy and to quench and heat the carbonized paddy, enabling the carbonized paddy to form a gas and a solid substance by means of solid-liquid separation. Wherein, the carbonized paddy is formed by burning paddy at a high temperature of 400-900° C. The carbonized paddy comprises at least 50% silica, at least 10% organic matter, at least 2% potassium, and at most 2% water. Furthermore, the first water quenching and heating area 10 comprises a tank body 11, a heater 12, a collection trough 13, and a delivery member 14. The tank body 11 is connected with the heater 12, the collection trough 13, and the delivery member 14. Through the heater 12, the carbonized paddy in the tank body 11 is heated. The collection trough 13 is configured to collect and store the solid substance separated from the carbonized paddy by means of gas separation. The delivery member 14 is used to deliver the carbonized paddy to the tank body 11 and to deliver the solid substance formed in the tank body 11 to the collection trough 13.
The first condenser 20 is connected with the first water quenching and heating area 10 and configured to condense the gas separated from the carbonized paddy into a liquid. Furthermore, an input end of the first condenser 20 is provided with a filter screen 21. The filter screen 21 is configured to filter impurities and to control the amount of the steam entering the first condenser 20. Moreover, an output end of the first condenser 20 is provided with a gate 22. The gate 22 controls the condensed liquid to be delivered to the second water quenching and heating area 30.
The at least one second water quenching and heating area 30 is connected with the first condenser 20 to receive the liquid which is condensed from the gas by the first condenser 20 and to perform a PH value test. When the PH value of the liquid is alkaline, the liquid is outputted and stored as a pesticide. Preferably, the water quenching device comprises a plurality of second water quenching and heating areas 30. A second condenser 40 is connected between every two of the second water quenching and heating areas 30. When the second water quenching and heating area 30 connected with the first condenser 20 tests and determines that the liquid doesn't reach the alkaline standard, the liquid is heated again by the second water quenching and heating area 30 and changed into a gas. The gas is condensed by the second condenser 40, and the condensed liquid is delivered to the next second water quenching and heating area 30 to give a PH value test. The second water quenching and heating area 30 comprises a tank body 31, a heater 32, and a PH value detector 33. The heater 32 and the PH value detector 33 are disposed in the tank body 31. The PH value detector 33 is electrically connected with the heater 32. When the PH value detector 33 tests the liquid received by the tank body 31 and determines that the liquid doesn't reach the alkaline standard, it will send a signal to the heater 32 and the liquid in the tank body 31 will be heated through the heater 32.
Furthermore, as shown in FIG. 3, the delivery member 14 has a bevel 141. When the paddy is inputted to the tank body 11, the paddy is slid on the bevel 141 smoothly, enabling the paddy to be delivered to the collection trough 13. In another embodiment, as shown in FIG. 4, the delivery member 14 is provided with a screw rod 142. When the paddy is inputted to the tank body 11, the screw rod 142 can control the speed and the volume of the paddy to be delivered to the tank body 11 so that the paddy can be heated evenly during delivery.
Accordingly, the method and the water quenching device for manufacturing a natural pesticide of the present invention use the carbonized paddy formed by burning paddy as the raw material of the pesticide. Through the procedures of water quenching, heating and condensation, the liquid separated from the carbonized paddy is tested by the PH value detector to determine whether the liquid reaches the alkaline standard or not. If yes, the liquid is outputted as a natural pesticide for use. Even if pests are drug-resistance to increase the dosage of the pesticide, the natural pesticide won't harm the environment and the human health. In addition, the carbonized paddy is quenched and heated to form a solid substance. The solid substance is further heated and crushed to form a small substance. The small substance is added with trichoderma, actinomyces, bacillus as a compound organic fertilizer.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
