Abstract
The utility model relates to a pipe powder sensor which is provided with a mounting base, and one end of the sensor is provided with a coaxial cable. The utility model is characterized in that one end of the sensor is provided with a probe in the shape of a long rod, wherein the probe is coated with a high molecular protective film which is condensation resistant, corrosion resistant and high temperature resistant, and the probe is made of wear resistant metal material. Because the powder sensor of the utility model is made of wear resistant metal material, the probe can be used for the measurement of a powder of strong abrasiveness in a high temperature pipeline; in addition, the probe is coated with the protective film which is condensation resistant, corrosion resistant and high temperature resistant, which enables the probe to have the functions of corrosion resistance, condensation resistance, high temperature resistance and wear resistance in a positive pressure and high temperature pipeline; the service life of the probe is enhanced, the phenomenon of condensation due to a temperature variation is avoided so as to affect the situation that a measuring system can not normally work, and the stability and the reliability of the measuring system are enhanced.
Description
Technical field
The utility model relates to a kind of powder sensor of pipeline powder monitoring device.
Background technology
The sensor of existing pipeline powder monitoring device, generally decide kind by its principle of work, as China Patent No. 01254197.4 disclosed " pipeline powder coal on-line monitor ", comprise computing machine, probe, probe is an elongated rod-shaped, there is a little measurement zone its front portion, the every side in its both sides all has aperture, one side has photoemitter, and a side has photelectric receiver, and photelectric receiver is connected with computing machine, monitor out with breeze airflow in the granularity and the concentration dependent transmitted light intensity fluctuating signal of pulverized coal particle, probe is connected with source of the gas, and device can be monitored the granularity of pulverized coal particle in the breeze airflow, concentration is diagnosed the operation conditions of coal pipe, during measurement unit operation is had no effect, measurement result also can be kept on the hard disk for analyzing use with the form demonstration of curve and data.The sensor of this monitoring device, monitor the granularity of pulverized coal particle in the pipeline and the principle of concentration owing to adopt the fluctuation intensity of transmitted light intensity, its inductive probe adopts photoemitter and receiver, in long-term abominable complicated production pipeline, work, transmitter and receiver are more easily destroyed by perishable thing, and often have bigger particle in the powder, also can exert an influence sensor.
The utility model content
It is a kind of simple and reasonable that the purpose of this utility model is to provide, and handling ease is measured accurately the pipeline powder sensor of firm and durable.
The technical scheme that its technical matters that solves the utility model adopts is; a kind of sensor that is used for powder measurement in the pipeline; sensor is provided with mounting seat; sensor one end is connected with concentric cable; it is characterized in that described sensor one end is provided with the elongated rod shape probe; be covered with one deck anti-condensation, anticorrosion, high temperature-resistant polymer diaphragm on the probe, probe adopts the wear-resistant metal material to make.
Described sensor probe one end is provided with insulation tube, and insulation tube is provided with retaining thread, and retaining thread one end is provided with securing member.
Be provided with the sensor mounting seat with described retaining thread corresponding position, mounting seat radially is welded on the tested pipeline.
Described sensor retaining thread and securing member one end are provided with the anti-condensation ring.
Described sensor anti-condensation ring one end is provided with sensor terminal box retaining thread, and sensor terminal box and concentric cable join.
The utility model powder sensor is owing to adopt the wear-resistant metal material to make; probe can be used for the measurement of the powder that wearability is very strong in the high-temperature pipe; add and be covered with one deck anti-condensation, anticorrosion, high temperature-resistant polymer protective film on the probe; make it in malleation, high-temperature pipe, have anticorrosion, anti-condensation, high temperature resistant, anti abrasive function; and probe improves serviceable life greatly; avoided because the dewfall phenomenon appears in temperature variation; to such an extent as to influence the situation of measuring system cisco unity malfunction, improved the stability and the degree of reliability of measuring system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1; a kind of pipeline powder sensor; sensor is provided with mounting seat; sensor one end is connected with concentric cable; sensor one end is provided with elongated rod shape probe 1; probe 1 adopts the wear-resistant metal material to make, and is covered with one deck anti-condensation, anticorrosion, high temperature-resistant polymer diaphragm on the probe 1.
Sensor probe 1 one ends are provided with insulation tube 2, insulation tube 2 is provided with retaining thread 3, and retaining thread 3 one ends are provided with securing member 4, because the pipeline internal-external temperature difference is bigger, have water vapor attached to being exposed on the outer sensor element of tested pipeline, so be provided with anti-condensation ring 5 at securing member 4 one ends; Be provided with the sensor mounting seat with retaining thread 3 corresponding positions, radially be welded on mounting seat on the tested pipeline after, sensor is inserted tested pipeline by mounting seat, tightening fastener parts 4 again, and sensor is fixed on the mounting seat.
Sensor anti-condensation ring 5 one ends are provided with sensor terminal box retaining thread 6, and sensor terminal box and concentric cable join, sensor to signal be input to monitoring device by concentric cable.
