Ultrasonic automatic filtration device for online water quality automatic analyzer {ULTRASONIC AUTOMATIC FILTRATION DEVICE FOR ONLINE AUTOMATIC WATER ANALYSIS SYSTEM}

The present invention relates to an ultrasonic automatic filtering device, and more particularly, to filter foreign substances such as suspended matter so that there is no obstacle to water quality analysis in a filtering device at a previous stage of supplying an analysis sample to an automatic online water quality analyzer that automatically analyzes water quality, The present invention relates to an ultrasonic automatic filtering device for an automatic online water quality analyzer, which removes foreign substances attached to a filter for filtering using ultrasonic waves, and thereby stably supplies an analysis sample to the automatic online water quality analyzer.

In general, automatic water quality analyzers frequently measure water quality items such as dissolved oxygen content and temperature, such as fish farms and fish farms, to check stable water quality conditions.

In particular, the automatic online water quality analyzer can receive the analyzed water quality information from a remote location and check the condition at any time, and therefore, it can be used remotely only when the sample for analysis is stably supplied to the automatic online water quality analyzer.

Since most raw water, which is an object of analysis, contains foreign substances such as various floating substances, it is difficult to accurately analyze each measurement sensor of the water quality analyzer.

Accordingly, a filtering device is provided as a device for supplying the analysis sample to the side of the automatic on-line water quality analyzer. Various filters may be installed in such a filtering device to remove suspended solids.

Thus, since foreign substances such as suspended solids are removed, the measurement is performed in a stable on-line automatic water quality analyzer.

On the other hand, in such a filtering device, since foreign substances such as floating matter adhere to the filter, the filtration performance is deteriorated, and therefore, manual work such as cleaning or replacing the filter from time to time is necessarily required.

Therefore, an appropriate treatment process for these suspended solids is urgently required.

Hereinafter, it will be described in detail with reference to the accompanying drawings.

That is, the ultrasonic automatic filtration device 10 for the automatic online water quality analyzer according to the present invention, as shown in the attached FIGS. It relates to an ultrasonic automatic filtering device (10) for supplying.

Such an automatic online water quality analyzer (not shown) is installed in a facility or place where various water quality conditions, such as pre-oxygen and turbidity, must be analyzed from time to time, such as a fish farm or fish farm, and relates to a technology prepared to be monitored online from a remote location. Accordingly, the technology for the automatic online water quality analyzer relates to an analyzer and analysis technology that can be generally applied, and a detailed description thereof will be omitted.

Accordingly, such an automatic on-line water quality analyzer may be generally installed in many places, and therefore, it would be difficult for a worker to frequently check the condition of the analyzer individually. However, the analysis sample, which is the water for analysis, must be supplied stably to obtain the desired analysis data for each cycle.

However, since the water quality test is generally performed for various environments, suspended matter or sediment may be included in general, and therefore, for the water quality test, the analysis sample is supplied through the filtration process, which is the previous step.

Since suspended solids may be attached to each filter during the filtration process of the analysis sample, the suspended solids attached to each filter should be removed in order to maintain a constant filtration performance.

Accordingly, in the automatic ultrasonic filtration device 10 for the automatic online water quality analyzer according to the present invention, suspended substances attached to each filter are removed by vibration according to ultrasonic oscillation.

Detailed configurations for this will be described.

That is, it relates to an automatic ultrasonic filtering device 10 for supplying an analysis sample obtained by filtering raw water by a raw water filter in an ultrasonic filter tank 20 to an automatic online water quality analyzer through an analysis sample supply pipe 161, FIG. 1 and FIG.

Therefore, the raw water to be analyzed is put into the raw water sample tank 21, and then is put into the analysis sample tank 22 after being filtered by the raw water filter.

The analysis sample filtered by the subsequent process is supplied to the on-line automatic water quality analyzer.

Accordingly, the raw water filter is provided as a screen mesh filter (31, screen mesh filter).

Furthermore, foreign matter in the screen mesh filter 31 is separated by the ultrasonic vibration generated by the ultrasonic vibration module 40, including the ultrasonic vibration module 40 located on one side of the analysis sample tank 22 and generating ultrasonic waves.

And the plate sheet membrane filter (34, plate sheet membrane filter), which is the secondary filter, has a membrane support (34c) fixed to the ultrasonic filtration tank (20) around the plate sheet type membrane (34b) as shown in FIG. and an analysis sample suction port 34a through which the sample is sucked to one side. In the plate sheet membrane filter 34, a separator having a pore size of 0.01 μm to 1 μm of the plate sheet membrane may be used.

In addition, in another filter, a hollow fiber membrane filter (35), as shown in FIG. 7, module headers 35a are provided on both sides of the hollow fiber membrane bundle 35b, and analysis samples are absorbed on one side of the module header 35a. The population 35c is provided. In the hollow fiber membrane filter 35, a separator having a pore size of 0.01 μm to 1 μm of the hollow fiber membrane may be used.

As such, in the automatic ultrasonic filtration device 10 according to the present invention, in addition to the screen mesh filter 31 as the primary filter, a plate sheet membrane filter 34 and a hollow fiber membrane filter 35 are provided as additional filters. As a result, the analysis sample is created by effectively removing foreign substances such as suspended matter from raw water by these plurality of filters.

Accordingly, the vibrator case 44 is fixed to the analysis sample tank 22, and the vibrator 42 connected by the power supply line 41 and the vibrator 43 are connected to the front plate of the vibrator case 44 by screws or the like. It is fixed to the inner surface.

Foreign substances such as floating substances are separated from the screen mesh filter 31, the plate sheet membrane filter 34, and the hollow fiber membrane filter 35 by the ultrasonic vibration.

In this way, raw water is supplied to the raw water sample tank through the raw water inlet pipe 114 for supplying raw water to the lower side of the raw water sample tank 21 of the ultrasonic filtration tank 20.

Next, the concentrated water of suspended solids accumulated under the raw water sample tank 21 is discharged through the suspended solids concentration outlet 12, the automatic discharge valve 13, and the drain pipe 14. That is, in response to the analysis sample filtered by the screen mesh filter 31, unfiltered suspended matter accumulates under the raw water sample tank 21, and such suspended matter flows through the suspended matter concentration outlet 12 and the drain pipe 14. is emitted through

In addition, when raw water is exceeded in the raw water sample tank 21, the raw water is drained through the raw water overflow drain pipe 15 and the drain pipe 14.
