Description

PH sensor with ultrasonic vibrator {PH SENSOR WITH ULTRASONIC TRANSDUCER}

The present invention relates to a pH measuring sensor equipped with an ultrasonic vibrator, and more particularly, a maintenance cycle for removing foreign substances such as sludge attached to the pH measuring sensor by drawing the pH measuring sensor from a tank containing a liquid such as waste liquid. PH measuring sensor equipped with an ultrasonic vibrator that can increase and adjust the separation distance between the pH measuring sensor and an ultrasonic vibrator for selectively cleaning the pH measuring sensor according to the waste liquid type, concentration, and outside temperature to be measured by the user It is about.

In general, due to serious environmental pollution, research on the measurement and removal of water quality is indispensable and active.

To determine water pollution, water quality sensors are used to measure the biological properties of the water environment, chemical properties such as trace elements in suspended solids, and turbidity of water, pH ions, and SS concentration.

In particular, Korean Patent No. 10-1057969 has a measurement body for measuring the characteristics of various water quality is formed at the bottom of the sensor body having an outer diameter, various water quality measurement in which the sensor cap is integrally coupled to the top of the sensor body In a fastener for fastening a sensor to a holder manufactured according to a measurement method according to a manufacturer or a country according to a measuring method, the fastening fastener is fitted to an outer diameter of the sensor body and a male thread part that is spirally fastened to a holder is provided at a lower outer peripheral surface. And a fastener formed with a diameter of a nut portion for rotating by using a wrench-type fastening tool to the upper portion of the male spiral portion, and formed into a larger diameter than the diameter of the male spiral portion, and fitted into an outer diameter of the sensor body. It constitutes a sliding ring that is in close contact with the lower end, and is fitted to the outer diameter of the sensor body and is in close contact with the bottom of the sliding ring Consists of the fixing ring, the donut-shaped packing that is fitted to the outer diameter of the sensor body to be in close contact with the bottom of the fixing ring, the fastener, sliding ring, fixing ring, packing to the sensor body sequentially inserted holder When the fastener is spirally fastened to the holder using the fastening tool after inserting into the sliding ring, the sliding ring is pressed into contact with the descending fastening ring, and the sliding ring is pushed on the upper part of the fixing ring to press the fixing ring in contact with the packing. The gap between the sensor body and the retaining ring and the gap between the sensor body and the holder due to the compression and expansion of the inner jaw of the sensor are tightly sealed, and the water quality sensor that is fastened to the holder by the rotation of the fastener does not rotate. A universal fastener for fastening a holder of a water quality measuring sensor configured to stop the cable transmitting a signal by being kept in a stopped state is disclosed. There.

However, there is a limitation that the universal fastener for fastening the holder of the water quality sensor can be applied only to a reservoir provided with a flange means for fixing the holder. For water quality measurement, it is necessary to measure with a holder in which the water quality sensor is disposed. Because the liquid must be in communication, the sensor can be used for a long time, so it is impossible to accurately measure the sensor due to foreign matters such as sludge contained in the water and the holder and the sensor. Removing the holder surrounding the water quality sensor by removing it in the tank, there was an inconvenience that the work of cleaning the sensor using a device such as a brush should be carried out from time to time.
