Description

{System for managing filters of microfiltration devices based on pressure}

The present invention relates to a filter management system for a pressure-based precision filtration device that can more accurately and easily confirm and guide the filter replacement time of a filtration device installed in a water supply facility.

In general, large-scale waterworks facilities are provided in cities to supply households with purified tap water according to legal standards, and since water purification and its facilities are professionally managed, distrust in tap water is relatively low.

However, most of the town-level water supply facilities such as remote areas or islands outside the city use valley water or groundwater for primary purification and then supply it to the village.

On the other hand, when the groundwater of a certain region contains heavy metal components harmful to the human body in its components beyond the allowable tolerance range, it is most important to filter the heavy metal components completely or harmlessly to the human body.

It is more important than anything else to remove even heavy metals harmful to the human body, and this is not only applied to a specific area, it can be said to be an absolute condition for functioning as a simple water supply in all unspecified areas.

A typical filtration device fills a filter to form a filtration tank, allows raw water to be filtered through the filtration tank, and passes the firstly filtered water through activated carbon or other filter media, for example, registered in Korea Patent No. 10-0560812 'Filtration system with self-purifying function' and Korean Utility Model No. 20-0458705 'Removable cartridge type filter' are disclosed.

However, when the lifespan of the filter of the filter device reaches the limit, it is difficult for the user to easily grasp information related to the life of the filter, and there is a problem that the filter cannot be replaced in time. There is a situation in which a problem occurs, and there is an urgent need to develop a system for replacing the filter in the filtration device to solve this problem.

However, in consideration of the fact that the use time and frequency of the main filtering device 210 is relatively larger than that of the auxiliary filtering device 220 , the size and filter capacity of the main filtering device 210 are larger than that of the auxiliary filtering device 220 . It is preferably designed, but it is not necessary to be limited thereto.

In addition, at least one of the main and auxiliary filtering devices 210 and 220 of the present invention is further provided with a photovoltaic power generation device that converts solar energy into electrical energy and outputs, through which the device installed adjacent to itself and itself ( For example, 100, 300, 400) of driving power may be produced and supplied by itself. In addition, when a power shortage occurs, commercial power is additionally used to cover the power shortage, thereby minimizing commercial power usage and ensuring stable power supply.

3 is a view for explaining a smart management method of the filtering device according to an embodiment of the present invention.

First, after identifying the main filtering device 210 based on the position value of the main filtering device 210, the supply pipe bypass device 100 is set to the first mode, and the first auxiliary supply pipe in which the main filtering device 210 is installed. As the fluid flows through (111), an environment that can be automatically filtered is established (S1).

Then, the operation of measuring and notifying the inlet pressure, the outlet pressure, and the filter housing internal pressure of the main filtering device 210 through the sensing device 300 is periodically and repeatedly performed (S2).

Then, the management server 400 calculates the filter replacement time based on the inlet pressure and outlet pressure of the main filtering device 210 and the filter housing internal pressure, and guides the position value of the main filtering device 210 and the filter replacement time. After creating a message, it is provided to a preset contact (S3).

At this time, the filter replacement time may be calculated based on the pressure change pattern by tracking and monitoring the pressure loss amount and the pressure inside the housing over a long period of time (eg, one year), and may be predicted based on the pressure change pattern.

Alternatively, when the amount of pressure loss exceeds the preset value or the pressure inside the filter housing increases to more than the preset value due to foreign substances, filter replacement can be requested immediately.

When the filter replacement time arrives or it is determined that the filter needs to be replaced immediately (S4), a message is generated to guide the location value of the main filtering device 210 and the need for immediate replacement of the filter, and then provided to the registered contact information, The device manager refers to this and allows the filter replacement operation to be performed (S5).

At this time, when filter replacement is performed while the internal pressure of the filter housing is increased to more than the preset value, the management server 400 additionally guides the increase in the internal pressure of the filter housing through a guide message, so that the operator recognizes the state and filters the filter. Allows the filter opening action to be performed after the pressure inside the housing has been reduced to an appropriate level.

That is, by providing additional information related to the pressure inside the filter housing in addition to simply requesting a filter replacement, the possibility of a safety accident due to the filter replacement operation can be minimized.

And at the same time as performing step S5, the supply pipe bypass device 100 is set to the second mode, so that the fluid flows through the second auxiliary supply pipe 112 rather than the first auxiliary supply pipe 111 while the filter of the main filtering device is replaced. While flowing through the secondary filtration device 220 installed in the second auxiliary supply pipe 112 to allow the foreign matter filtering operation to be continuously performed (S6).

This state is maintained until the filter replacement of the main filtering device is completed. If the filter replacement is completed, the supply pipe bypass device 100 is set back to the first mode and then re-enters step S2 to filter the filter device. It allows the management operation to be continuously performed (S7).

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications can be made by those having the knowledge of
