Description

Automatic fog spraying system for agricultural and livestock control}

The present invention is an automatic fog spray system for agricultural and livestock control. It enhances the function of removing foreign substances and residues remaining in the pipe after system control. More specifically, it uses the compressed air generated by the compressor to spray the water in the storage tank. The cleaning function completely removes foreign substances and residues by forcibly discharging foreign substances accumulated in the filtration filter, piping filter in the pipe, and nozzle filter in the spray nozzle section through the low-pressure discharge socket and discharge solenoid valve installed at the end of the nozzle line. This is about an automatic fog spray system for enhanced agricultural and livestock pest control.

In general, nozzles are used to spray high-pressure water or chemicals for various purposes, such as spraying and supplying water or chemicals to plants in various industrial fields, wastewater treatment plants, and agriculture. There are a wide variety of sizes and shapes, and the one suitable for the purpose and purpose is selected and used as needed.

However, if the nozzle used for the above purpose is used for a long period of time or if spraying through the nozzle is stopped and resumed from time to time, the spray hole that sprays water or chemicals may cause sediment or dryness of chemicals in the pipe that supplies water or chemicals. Alternatively, it may gradually become clogged due to hardness in the water, resulting in a problem of not being able to supply water or chemicals to the target object, resulting in significant disruption to work.

As an example of the above problem, in a spray system that automatically sprays water or chemicals to agricultural plants, the chemicals or water are supplied by spraying them through a spray nozzle, but the chemicals may coagulate or foreign substances that may be generated in the pipe may be present in the filter or If there is a build-up in the spray nozzle, the filter cannot function properly, causing a problem in which chemicals or water are not properly filtered and supplied.

In addition, when the injection nozzle and filter become clogged, the facility must be shut down, the nozzle disassembled, the clogged injection hole repaired and opened, and then reassembled to operate the facility. This results in a decrease in productivity due to facility shutdown and the disassembly and combination of the nozzle. It caused inconvenience, etc.

The prior patent is to recover the fluid remaining in the pipe after the work is completed by spraying only compressed air through the nozzle and stopping after a certain period of time after the injection is finished, and to spray only compressed air for a certain period of time, so that the fluid remaining in the pipe or stuck on the surface of the nozzle is recovered. An injection system is described that is installed to eliminate clogging of the nozzle's injection hole by discharging remaining residues and has a function to prevent the clogging of the injection nozzle.

However, the prior patent only describes a configuration for removing foreign substances with a spray nozzle, so there is a problem in that foreign substances accumulated in the filter cannot be removed. Since the prior patent is designed to supply air directly to the nozzle, foreign substances in the filter cannot be removed. There is a problem that cannot be resolved.

It is configured to further include 3 solenoid valves (130).

In addition, the control unit 140 is formed on the pipe connecting the pipe filter 30 and the distribution unit 50 to prevent the compressed air of the compressor 100 from flowing back into the storage tank unit 1 when cleaning the pipe. A first non-return valve 40 driven according to a signal; A second backflow prevention device is formed in the pipe connecting the second solenoid valve 110 and the distribution unit 50 and is driven according to a signal from the control unit 140 to prevent the drug from flowing back into the compressor 100 when the drug is sprayed. It is configured to further include a valve 120.

The storage tank unit (1) has a stirrer (not shown) connected to the power spray unit (20) and a filtration filter (10) installed at the discharge port. In addition, the third electronic valve 130 connected to the control unit 140 injects compressed air into the storage tank 1 in advance before the injection nozzle unit 70 starts to ensure that the medicine is sufficiently mixed.

The third solenoid valve 130 continues to inject even while the nozzle is spraying from the injection nozzle unit 70, and is opened to prevent the drug from sinking or foreign substances from accumulating in the filtration filter 10, thereby allowing the compressed air of the compressor 100 to be used. It is delivered to the storage tank unit (1).

Here, the third electromagnetic valve 130 is opened and closed by the control unit 140, and when the compressed air mixes the medicine, it is sucked into the power spray unit 20 through the filtration filter 10. The chemical that has passed through the power spray unit (20) is filtered again through the pipe filter (30). At this time, the filtration network of the piping filter 30 is a strainer that can be cleaned by periodically separating the filtration network filter with a thickness of 120 mesh or more. Foreign substances filtered through the strainer filter are recovered into the storage tank by a recovery system, and can be disassembled and cleaned periodically.

The first non-return valve 40 is installed to prevent the high-pressure compressed air passing through the second solenoid valve 110 from flowing back into the storage tank unit 1 when cleaning the pipe, and conversely, the high-pressure spray nozzle unit 70 ), a second non-return valve 120 is installed to prevent the drug from flowing back into the compressor 100 when nozzle spraying is performed.

Here, in order to spray the nozzle of the injection nozzle unit 70, the medicine is supplied from the storage tank unit 1 to the power spray unit 20, the pipe filter 30, the first non-return valve 40, and the distribution unit 50. ), the first solenoid valve 60, and the nozzle filter 71, the air in the pipe interferes with the flow of the drug, preventing uniform spraying throughout the nozzle. At this time, the low-pressure discharge socket 80 (normally open) is always open, so that the air in the pipe is pushed by the compressed agent and discharged through the low-pressure discharge socket 80.

Then, when the air in the pipe is discharged and the high-pressure medicine reaches the low-pressure discharge socket (80), the low-pressure discharge socket (80) is closed. When the same pressure is applied to all nozzles upon closing, the check valve in the nozzle opens and spraying occurs from all nozzles.

In addition, even if the pipe cleaning is finished and the fog spray system is stopped, the low-pressure discharge socket 80 is always open so that the residue existing in the pipe is automatically discharged, so that it can always be kept clean.

When the injection nozzle unit 70 is completed, the control unit 140 operates the discharge electronic valve 90 through a signal to forcibly discharge foreign substances and residues present in the pipe by injecting compressed air from the compressor 100. At this time, the compressed air of the compressor 100 opens the second solenoid valve 110 according to a signal from the control unit 140, and is supplied to the second check valve 120, the distribution unit 50, the first solenoid valve 60, By being discharged through the nozzle filter 71 and the discharge solenoid valve 90, residues and foreign substances are removed.

Here, when the second electromagnetic valve 110 is opened to clean the pipe, the first non-return valve 40 is attached to prevent compressed air from flowing back into the storage tank, and foreign substances in the pipe and accumulated in the nozzle filter 71 are prevented. Foreign substances present are forcibly discharged to the outside through the discharge solenoid valve (90) by high-pressure compressed air.

The control unit 140 provides a signal to the third solenoid valve 130, the power spray unit 20, and the first solenoid valve 60 to operate the spray, and when cleaning the pipe, the compressor 100 is compressed. Air is operated by giving a signal to the second solenoid valve 110, the first solenoid valve 60, and the discharge solenoid valve 90.
