Description
Technical field
The present invention relates to instrument fields, more particularly to a kind of radar level that can clear up antenna surface dust automatically
Meter.
Background technique
Radar levelmeter is the instrument for carrying out level gauging to material in feed bin using the measurement method of microwave pulse, can be pacified
Loaded in various metals, nonmetallic vessel or pipeline, contactless continuous survey is carried out to the level of liquid, slurry and particulate material
Amount.It is big suitable for dust, temperature, pressure change, there is occasion existing for inert gas and steam.Radar levelmeter has to human body
And the equal fanout free region of environment, it is not influenced, is not influenced by change in dielectric constant by medium specific gravity, it is excellent not need scene tune-up etc.
Point whether needs industry, or the consideration economical and practical to customer, is all good selection.But the production of measured medium
Raw dust can be assembled on antenna, will affect the transmitting of radar wave at this time, and radar wave cannot even issue when serious, thus shadow
Ring normal production work.
Summary of the invention
In order to overcome radar levelmeter during the work time, the dust that measuring medium generates can be assembled on antenna, influence
The problem of measurement accuracy, the present invention provide a kind of High Accuracy Radar level meter, this kind of High Accuracy Radar level meter is in surface dirt
When excessive, dust can be cleared up automatically, to guarantee that measuring work accurately carries out.
The technical solution adopted by the present invention to solve the technical problems is: a kind of High Accuracy Radar level meter, including radar
Level meter ontology, controller and air compressor machine, the controller are set at the top of feed bin, and the radar levelmeter ontology is connect with feed bin
Place is equipped with high-precision mass sensor, and the high-precision mass sensor is connected with controller, and the controller includes storage core
Piece is fixed with outer jet ring on the feed bin of the radar levelmeter body upper part, and the outer jet ring is hollow structure, described outer
Jet ring is equipped with several nozzles, and the outer jet ring is connected with air compressor machine by tracheae, is set on the radar levelmeter ontology
There is antenna house, emitting radar waves device is equipped in the antenna house, the antenna house inner wall is equipped with interior jet ring support, described interior
Jet ring support is equipped with interior jet ring, and the interior jet ring is hollow structure, and the emitting radar waves device is located at interior jet ring
Top, the interior jet ring are equipped with several fumaroles, one of them described interior jet ring support is hollow structure, this is hollow interior
Jet ring support one end is communicated with interior jet ring, and the other end passes through antenna house and is connected by tracheae with air compressor machine, the air compressor machine
It is connected with controller.
The preferred controller is single-chip microcontroller.
The permission maximum value of this weight of radar levelmeter is preset in storage chip, when dust is on radar levelmeter surface
When gathering, the raising of this weight of radar levelmeter will lead to, when high-precision mass sensor detects that quality is increased to preset value
When, controller can make air compressor machine spray gas, and the nozzle of gas from the outside and internal fumarole spray the ash for blowing away surfaces externally and internally
Dirt, there are field angles for the radar wave of emitting radar waves device transmitting, therefore interior jet ring will not influence normal work.
The beneficial effects of the present invention are: the dust that radar levelmeter surface is gathered can be found in time, and clear up, guarantees in time
Measure the accurate of work.
