Online ammonia nitrogen sensor

Abstract

The invention discloses an online ammonia nitrogen sensor comprising a machine body and an antiskid block fixedly arranged at the upper end of the machine body, a display screen is arranged on the front side wall of the machine body, a plurality of control buttons are arranged on the periphery of the display screen, and the lower end of the machine body communicates with a fixed cylinder; a telescopic cylinder is slidably arranged in the side wall of the fixed cylinder through a sliding mechanism, a probe is fixedly arranged at the lower end of the telescopic cylinder, one side of the slidingmechanism is connected with a first connecting rod, the first connecting rod is arranged in the side wall of the machine body, and a first bevel gear is fixedly arranged at the upper end of the firstconnecting rod; the first bevel gear is meshed with a second bevel gear, and the second bevel gear is fixedly provided with a second connecting rod. According to the online ammonia nitrogen sensor, the pollution and the harm on a human body due to the sputtering on the surface of the human body are avoided during the detection of the ammonia nitrogen content in water, and the safety of the deviceis increased.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an online ammonia nitrogen sensor. Background technique [0002] Ammonia nitrogen wastewater mainly comes from chemical fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc. A large amount of ammonia nitrogen wastewater discharges into water bodies not only causes eutrophication of water bodies, causes water body black and smelly, but also increases the difficulty and cost of water supply treatment, and even affects People and organisms have toxic effects, so we need to purify the ammonia nitrogen in the water in time, and in this process, we often use the ammonia nitrogen sensor to first detect the ammonia nitrogen content in the water; [0003] The existing ammonia nitrogen sensor detects the nitrogen content in the water in a traditional way. The staff often wear gloves and put the probe of the sensor into the water. Although the nitrogen-containing waste...
