AI Technical Summary

Technical Problem

After long-term use of existing exhaust gas detectors, due to the residual oil fumes and impurities, the temperature sensor is easily blocked, affecting the accuracy of exhaust gas temperature detection.

Method used

An environmentally friendly exhaust gas detector is designed. A filter plate is fixed at the port of its intake pipe. The filter plate filters the oil fume in the exhaust gas, and passes through the mechanical structure of the fan blade, the movable plate and the positioning block to move the storage block up and down, and the brush cleans the oil fume impurities on the filter plate to prevent blockage.

Benefits of technology

It effectively avoids oil fumes impurities entering the sensor body, prevents blockage, and ensures the stability and accuracy of exhaust gas temperature detection.

Abstract

The invention relates to the technical field of environment-friendly waste gas, in particular to an environment-friendly waste gas detector. A filter plate is fixed to the inner wall, close to a port, of an air inlet pipe, a rotating shaft movably penetrates into the air inlet pipe, the end of the rotating shaft is located in a protective cover, fan blades are fixed to the outer surface, located in the air inlet pipe, of the rotating shaft, a positioning rod is fixed to the end of the rotating shaft, and the outer surface of the positioning rod is movably sleeved with a positioning block; the sensor has the advantages that when an engine exhausts waste gas, the waste gas can enter the sensor body from the gas inlet pipe, the filter plate is fixed to the position, close to the end opening, of the gas inlet pipe, so that oil smoke in the waste gas can be filtered through the filter plate, and the oil smoke in the waste gas can be filtered out through the filter plate; the waste gas entering the sensor main body does not contain oil smoke, so that the oil smoke in the waste gas is prevented from entering the sensor main body to block the sensor main body.
