Floating ball measuring device of industrial wastewater PH instrument

Abstract

The invention relates to a floating ball measuring device of an industrial wastewater PH instrument. The device comprises a measuring electrode, a water inlet pipe, an outer sleeve, a floating ball and a floating limiting rod, the measuring electrode is arranged in the outer sleeve in a height-adjustable manner, the water inlet pipe is arranged at the bottom of the outer sleeve, the floating ball is arranged on the peripheral side of the outer sleeve in a sleeving manner, one end of the floating limiting rod is connected with a wastewater pool wall, and the other end of the floating limiting rod is connected with the top of the outer side wall of the outer sleeve. Compared with the prior art, based on the cooperation of the floating ball and the outer sleeve, the device can be automatically lifted and does not turn over, so that the measurement range of the device is not influenced by the liquid level of a measured water sample and the size of a pool, the stability of the device is further improved, and the service life of the device is further prolonged.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a float measuring device for a pH meter of industrial wastewater. Background technique [0002] At present, the structural installation of sensors equipped with pH electrodes can be divided into three categories: the submerged type is mainly used for immersion installation from the liquid surface of reaction tanks, pools and sealed containers, etc.; the flow-through type is mainly used for pipeline installation, which can be directly inserted into the pipeline. Flow-through installation of truncated pipeline or bypass sampling method needs to add glass electrode, reference electrode and temperature electrode, which is suitable for micro-measurement, so the cost is also high, and it is not suitable for industrial waste water tanks; the oblique insertion type is mainly used for inconvenient top installation. The container, with a hole from the side of the container. All installa...

Problems solved by technology

[0003] There is a problem that the electrode is easily damaged in the pH measurement of industrial wastewater, which leads to the frequent damage of the electrode during the daily measurement and sampling process and needs to be replaced, which increases the maintenance cost

Now a simple PH measuring device is basically used. In daily use, it is often found that water enters due to the poor sealing of the pipe fittings used, causing the balance of the device to be broken, and the glass electrode and the lead wire are always in contact with the water sample.

The glass electrode is easily damaged without protection, and the connection between the lead wire and the electrode is poorly sealed, so the electrode often needs to be replaced
