The feed bin under the charging state full of dust and disturbance within 100 meters.The instrument of the relevant technologies such as capacitor or guided wave radar
TDR will receive very strong tension loading when level declines in blowing, may be damaged instrument or silo roof drawing is folded.Weight warp
The problem of often burying hammer, needs often to repair, other most of mechanical instrument are also in this way.And operating condition dusty may
Ability beyond non-contact type ultrasonic system for level gauging.The frequency modulated(FM) radar technology of high frequency is especially suitable for this large-sized solid material
The level gauging in storehouse.
Radar wave is a kind of electromagnetic wave of special shape, and the property of electromagnetic wave is utilized to be expected in radar level gauge
Position detection.The physical characteristic of electromagnetic wave is similar to visible light, and spread speed is equivalent to the light velocity.
When measuring limestone powder bin level or the biggish level of dust concentration using radar levelmeter, it is easy in radar object
Dust is sticked on the meter antenna of position, cause radar levelmeter measurement error big or generates false level.
Utility model content
For the above technical problems, the utility model provides a kind of uninterrupted dust guard of radar levelmeter,
Lead to measurement error to solve the problem of that existing radar levelmeter is easy to be infected with dust on antenna, the radar levelmeter not between
Disconnected dust guard can effectively stop contacting with each other between dust and level meter antenna, improve the measurement essence of radar levelmeter
Degree.
The utility model provides a kind of uninterrupted dust guard of radar levelmeter, including radar levelmeter, dust cover, wind
Pressure pipeline, pipeline pressure table, gas dry filter and wind pressure pipeline cut-off gate, the bottom of the radar levelmeter are provided with object
Position meter antenna, the dust cover is located at the bottom of the radar levelmeter, and the level meter antenna is located in the dust cover,
The bottom opening of the dust cover, the dust cover include internal layer and outer layer, are formed with gas between the internal layer and the outer layer
Body cavity, the wind pressure pipeline access the gas cavity by the outer layer of the dust cover, and the internal layer of the dust cover offers
Multiple ventholes, the venthole is towards the level meter antenna, along the gas flow direction of the wind pressure pipeline, the pipeline
Pressure gauge, the gas dry filter and the wind pressure pipeline cut-off gate are set gradually on the wind pressure pipeline.
Further, the wind pressure pipeline is the stainless steel tube of diameter 8mm.
Further, the venthole is the circular hole of diameter 0.5mm.
Further, the wind pressure pipeline cut-off gate is solenoid valve.
Further, the dust cover is inverted funnel-shaped structure.
The uninterrupted dust guard of this radar levelmeter is provided with dust cover in the outside of level meter antenna, by dust boot design
At double-layer structure, interlayer is hollow, the different aperture of dust cover internal layer circumferentially-spaced, and the outer layer of dust cover introduces dry by gas
Gas after dry filter.When putting into operation, air pressure is adjusted, the gas pressure inside the uninterrupted dust guard of radar levelmeter is greater than
The pressure of level tank body is measured, it is continual that level meter antenna is cleaned, simultaneously because radar levelmeter is uninterruptedly dust-proof
The pressure of device is greater than the pressure of measurement tank body, effectively uninterruptedly can prevent dust from entering in dust cover, prevent from being adhered to
Above level meter antenna.
