The present invention relates to a water purification device of a liver water supply facility. More specifically, in case of abnormality such as filter pollution of 1st and 2nd level, the water purifier operates normally and the administrator is notified by wire or wireless, and the filter is broken or the R / O pump is stopped. In case of an emergency such as, the alarm signal is notified and the power supply device of the unmanned management type abnormal water supply facility in which the power is cut off for the safety of the facility.

Small towns such as mountain books, farm villages, and fishing villages are often not included in the metropolitan water supply system because of poor economic conditions.

However, these liver abnormal water supply facilities are often located in remote areas far away from the authorized person to obtain cleaner raw water, so it is difficult for managers to find them frequently. Therefore, drinking water pollution and machinery due to exhaustion of disinfectant solution are difficult to find. There is a problem that immediate actions are not taken well when water supply is interrupted by a fault.

In addition, since a non-specialist such as the village chief is in charge of the management, minor abnormalities such as replenishing disinfectant solution can be solved by the administrator. After some time in the process of importing and repairing the equipment specialists, there is a problem that the length of water is long.

In order to solve the management problems caused by the maintenance and repair of such abnormal water supply facilities, the unmanned wired / wireless imaging device monitors the operation status of various subsidiary facilities in real time and sends an alarm to the control station and the site manager in case of problems so that immediate action can be taken. An unmanned integrated management system (Registration Utility Model No. 363893, Utility Model Holder: Dongyang Chemical Co., Ltd.) has been proposed. However, the unmanned integrated management system is required to support large-scale investment and administrative support because the integrated facilities and water quality of Gansu-do is managed by a management company linked to an administrative institution. The management status / analysis status / facility status / B and a server for mounting it, various facility devices and water quality measurement equipment, video equipment, etc. are required, so the system configuration is very complicated and can not be operated by experts.

The present invention has been made to improve such a conventional problem, by monitoring the presence of abnormality of the pump element and filter element directly affecting the water quality or water supply of the components of the liver water supply facilities to facilitate the management of water purification equipment by non-experts Its purpose is to provide an unmanned managed water supply system for unattended management, which can notify managers of abnormal operation or failure so that immediate actions can be taken. In addition, according to the present invention, when the water purifier is normally operated according to the degree of severity of the pump failure or filter contamination, the fact that the water purifier is normally operated is notified to the administrator via wired or wireless, and in case of an emergency, the alarm signal is notified to the administrator. Another purpose is to provide a water purification system for a K-water facility that has been blocked so that the rest of the facility can be protected.

The present invention for solving the above technical problem is the raw water supplied from the water intake pump through the upstream pipe is purified water and then sent to the water storage tank through the downstream pipe, in the water purification device of a simple water supply facility, through the upstream pipe A filter unit for removing impurities in the supplied raw water; A pressure detection sensor installed in the filter part or the downstream pipe to measure the water pressure of the raw water passing through the filter part; And a control panel that cuts off the power while the alarm signal is transmitted to the manager terminal when the abnormality is acceptable and compares the water pressure of the raw water measured by the pressure detection sensor with the set value. Characterized in (claim 1).

Preferably, the filter unit is composed of two or more filters having different pore sizes, a pipe connected between the filters, and a pressure detection sensor installed in the pipe to increase water purification efficiency.

More preferably, an additional R / O pump is installed in the upstream pipe and a control switch of the same R / O pump is installed in the control panel so that an alarm signal is generated by the control panel when the current detected by the control switch is abnormal. Power is cut off while being transmitted to (Claim 2), or when the current is abnormally detected in the operation switch of the intake pump installed in the control panel, the alarm signal is sent to the manager terminal to cut off the power.

The control panel may include a transmitter for transmitting a notification signal or an alarm signal to an external device, a circuit breaker for shutting off the power of the water intake pump or the R / O pump when the alarm signal is externally transmitted, and controlling the transmitter to detect the pressure detection sensor. It may be configured to include a controller for comparing the value and the set value to determine whether there is an abnormality. (Claim 5)

The alarm signal indicates that the water pressure measured by the pressure detection sensor is below the minimum water pressure or above the maximum water pressure, so that the operation of the water purifier must be stopped or the R / O pump or the intake pump in the state where the water purifier of the present invention is set to the operation mode. Is a signal that is transmitted to the outside when no current is detected in the control switch or the operation switch.The notification signal is a pressure between the minimum and maximum hydraulic pressures, but the filter is contaminated and needs replacement or excessive pressure. If the water purifier is unstable, it is a signal sent to the outside.

The notification signal and the alarm signal are transmitted to the manager terminal through wired or wireless, and the manager terminal notifies the manager of which part is a problem through a beacon or an LED or a speaker. Therefore, if the abnormality that can be directly handled according to the display content of the manager terminal, the manager can take immediate action in the field, and if it is required to replace the pump, etc. can be immediately referred to the expert can be normalized quickly.

In addition, the simple water supply facility to which the water purification device of the present invention is applied may be a structure in which a pretreatment filter is additionally installed in an upstream pipe as shown in FIG. 2, or a portion of the concentrated water discharged from the filter part is returned to the upstream pipe. have.

Hereinafter, on the basis of the accompanying drawings will be described the configuration and operation of the liver water supply facility is installed water purification apparatus of the present invention.

Example  One

1 is a model diagram showing a simple water supply facility of an embodiment according to the present invention.

In the figure, the raw water sucked up from the underground core by using the intake pump 10 is introduced into the R / O pump 20 through the pipe 80, the R / O pump (Reverse Osmosis pump) (20) The water pressure of the raw water is increased in pressure and is sent to the filter part 30. In the present embodiment, the filter unit 30 is the primary R / O filter 31 and the secondary R / O filter 33 and the tertiary so that the filter having a smaller pore (pore) is located toward the downstream side The R / O filter 35 is connected in series with the pipe, and the pressure detection sensor 50 is provided adjacent to the discharge side of these R / O filters 31, 33, 35, respectively. Therefore, the raw water introduced into the apparatus is purified through clean water with little impurities while passing through these R / O filters 31, 33 and 35, and then connected to the downstream side of the filter unit 30. It is stored in the reservoir tank 60 through 80.

In addition, the intake pump 10, the R / O pump 20 and the pressure detection sensor 50 are electrically connected to the control panel 40, respectively, to send a detection signal to the control panel 40 or to control the control panel. Will receive. For example, the pressure detection sensor 50 detects the water pressure of the raw water discharged from each R / O filter and sends the result to the control panel 40, while the intake pump 10 and the R / O pump 20 are the control panel. It is driven or stopped by the on-off operation of 40.

As shown in FIG. 1, the control panel 40 includes an analog signal of the breaker 41 and a pressure detection sensor 50 that block power from being supplied to the intake pump 10 or the R / O pump 20. A / D converter 47 for converting into a digital signal, a transmitter 45 for sending a notification signal or an alarm signal to a remote administrator terminal 70 by wire or wireless, and controlling / setting / compare / compare / It is comprised by the control part 43 which performs a command process.

Accordingly, the current or voltage flowing through the control switch or the operation switch of the intake pump 10 or the R / O pump 20 in the operation mode state is detected and when the value is abnormal, for example, when the current is not detected as one breaker ( If 41 is set in the control unit 43 so that the alarm signal is transmitted while the operation is performed, the control unit 43 executes as set in the control unit when the corresponding condition is satisfied. In addition, the maximum water pressure 12㎏ / ㎠ and the minimum water pressure 3㎏ / ㎠ in the control unit when the water pressure is out of this range is detected by the pressure detection sensor 50, the breaker 41 is operated to send an alarm signal In the meantime, when a value of 4 kg / cm 2, 8 kg / cm 2, or the like, the operation state is maintained as it is, the manager terminal 70 may be set to transmit a notification signal for notifying the filter replacement time. Here, since the water pressure detected by the pressure detection sensor 50 is generally lowered as the filter is more contaminated, a 2-3 signal value is set between the minimum water pressure and the normal water pressure to notify the manager terminal 70. It is efficient to let it be sent a couple of times.

As described above, according to the present embodiment, it is possible to secure an unmanned liver water supply facility without significantly changing the configuration of the conventional water purifier. In addition, it is possible to solve the problem of a long period of time by checking the main fault areas of the facility such as a pump or a filter and notifying the manager in real time so that the manager can immediately respond to an abnormal occurrence. In addition, when a serious abnormality occurs, it is possible to prolong the life of the device by stopping the operation to notify the administrator of the fact as soon as possible so as not to cause further problems. In addition, it is possible to easily determine where there is a problem by looking at the notification signal or alarm signal, so that the facility can be managed even if the expertise is insufficient.

Example  2

Figure 2 shows a liver water supply facility according to another embodiment of the present invention.

To explain the difference from the above-described first embodiment, first, an inexpensive pretreatment filter 37 is additionally installed between the intake pump 10 and the R / O pump 20, and the expensive R / O arranged on the downstream side. The filter can be used for a long time. In addition, a portion of the concentrated water containing a large amount of impurities is conveyed to the upstream pipe through the conveying line 90 to reduce the amount of dirt disposed to the outside during the water purification process. Otherwise, since there is no difference in comparison with the first embodiment, the same reference numerals are given to the same components as in the first embodiment, and description thereof will be omitted.

As discussed above, according to the unmanned water purifying apparatus of the present invention, simply check the abnormality of the pump / filter affecting the water quality or the water supply amount by changing the water pressure or current, and notifying the manager when the result is abnormal. By doing so, maintenance and repair of the management facilities can be done immediately.

In addition, there is an advantage that it is easy to manage the water purifying device by a non-expert because it notifies the administrator to distinguish where the abnormality occurs and how severe the abnormality. Furthermore, in the present invention, the power supply is cut off for the protection of the facility while notifying the administrator of the alarm signal in an emergency, thereby extending the service life of the facility.
