CN2198859Y - Device for removing agricultural chemicals on surface of fruits and vegetables - Google Patents

Abstract

The utility model relates to a device for removing agricultural chemicals on the surface of fruit and vegetables, which comprises a pump, a timer and an ozone generator. The timer is provided with monostable time-delay circuits, and each monostable time-delay circuit is composed of a 555 time-base circuit, a resistance R, a capacitance C and a switch AN. The operating state of a relay can be triggered by the monostable time-delay circuits. The device uses three monostable time-delay circuits which are connected in parallel. The ozone generator is composed of a rectifying diodes D1, a unidirectional controlled silicon KD, a capacitance C1 and a triggering transformer BB. The ozone generated by the ozone generator can be blown into a guide pipe to enter the water in the container by the pump to complete the whole process of the machine. The purpose of removing agricultural chemicals on the surface of the fruit and the vegetables can be achieved by using the ozone which has strong oxidation performance and is easy to dissolve in water.

Description

Device for removing agricultural chemicals on surface of fruits and vegetables

The utility model proposes a kind of device that utilizes the ozone technology sterilization--remove the device of fruit, vegetable surface agricultural chemicals.

Present ozonizer is a lot, has plenty of the refrigerator disinfecting of being used for deodorizing, also has plenty of the air sterillization of being used for, purification.What also have is used for water treatment.Their structure mainly contains ozone generator, and it comprises ozonizer and simple control circuit, but is used for the processing of fruit, vegetable surface agricultural chemicals is not also had, and mainly is also undesirable to the control of the concentration of ozone.

The purpose of this utility model is the problem at above-mentioned existence, proposes a kind of device of removing fruit, vegetable surface agricultural chemicals.

Technical solution of the present utility model: comprise pump, timer, ozone generator, the output 11 and the relay J of timer are wherein joined, the A end of the termination alternating current 220V of the normally opened contact J1 of relay, the other end be with ozone generator 10 in the anode tap of controllable silicon KD and an end of the primary coil of transformer BB join, the other end of primary coil joins by the positive pole of capacitor C 1 with crystal diode D1, the control utmost point of controllable silicon KD joins by the negative terminal of resistance R 1 with diode D1, the negative terminal of D1 and the B of alternating current 220V end join, serial connection ozone generating pipe G between secondary coil two ends of transformer BB.

Accompanying drawing is an electric theory structure schematic diagram of the present utility model.

Three 555(time base circuits among the figure) form timer (prior art).The 10th, ozone generator (O ₃), G is ozonizer (prior art), and J is a relay, and R, RO are that resistance, C are electric capacity, and BB is a transformer, and KD is a controllable silicon, and AN is a switch.

Further describe technical scheme below in conjunction with accompanying drawing:

After rectification, be output as the 12V DC voltage, the single stabilization delay circuit that timer is made up of 555 time base circuits, resistance R, capacitor C and switch AN, AN place normally open at ordinary times, time base circuit (555) is in reset mode, at that time during basic circuit No. 3 pin output low levels, relay J is not just worked, and when AN gives a triggering signal, 555 are set, 555 No. 3 pin are promptly exported high level, relay work, its normally opened contact closure, O ₃Generator is also worked, and the interior discharge tube of substrate this moment is cut off, and capacitor C is in temporarily steady state by resistance R to its charging, circuit.When the voltage on the C was charged to 2/3VDD, 555 resetted, its No. 3 pin output low levels; Relay quits work, and J1 discharges, O ₃Generator quits work, and therefore, capacitor C, resistance R have determined the working time of this machine, and this device uses the single stabilization delay circuit of three parallel connections, obtains three different working times (5 minutes, 10 minutes, 15 minutes) respectively.Ozone generator 10, by commutation diode D1, one-way SCR KD, capacitor C 1 and triggering transformer BB form, and because of discharging and recharging at two ends that trigger transformer of C1 produces high pressure, excite O ₃, generator work produces O ₃, the power supply of air pump is an alternating current 220V, it will be by O ₃The O that generator produces ₃Be blown in the water that conduit enters container, finish the overall process of this device.This device is to utilize O ₃Strong oxidation and characteristic soluble in water decompose fruit, the vegetable surface residues of banned pesticides are innocuous substance, and kill the bacterium in the water, reach the purpose of removing fruit, vegetable surface agricultural chemicals.
