Abstract
The utility model discloses an anticorrosion type horn antenna, which comprises an antenna, anticorrosion layers and a flange. The antenna is in the shape of a large-aperture trumpet and is arranged above the flange. Both the inner surface of the horn antenna and the lower surface of the flange are provided with the anticorrosion layers. The horn antenna is made of aluminum alloy or metal materials. The anticorrosion layers, which are made of anticorrosion materials with a low dielectric constant, are attached or sprayed on the inner surface of the horn antenna and the lower surface of the flange. The flange is made of metal materials. Compared with the prior art, the anticorrosion type horn antenna is more adaptable to complex working conditions and can meet the requirements of anticorrosion and anti-compression while ensuring the signal receiving strength. Meanwhile, the anticorrosion type horn antenna is easy in machining and production.
Description
Technical field
The utility model relates to radar levelmeter, relates in particular to the application of the pulse radar level meter under the complex working conditions such as burn into pressure, strong steam, belongs to the level gauging technical field.
Background technology
During the modern industry level gauging was used, the pulse radar level meter was widely used in level gauging as a kind of contactless radar levelmeter.The operation principle of pulse radar level meter is: pulse electromagnetic wave is launched by antenna, arrives the measured object surface, receives in the measured object surface reflection and by antenna; Transmit and receive the electromagnetic time difference through calculating and just can calculate the distance of instrument between the measured object surface.Antenna is as the electromagnetic device that transmits and receives, and its structure influence transmits and receives the power of signal, and can the decision instrument operate as normal.
The pulse radar level meter is in measuring process, and environmental condition can especially produce bigger influence to antenna to instrument.The part measured medium has strong steam, and has the characteristic of deep-etching, like the strong acid of various high temperature; Even the work condition environment that has also has certain gas pressure.
Because strong steam has very strong attenuation to electromagnetic transmission, the instrument that adopts generally all is the horn-like radar antenna of the big receiving area of heavy caliber; The antenna that corrosive environment then requires anti-corrosion material to process; Have under the operating mode of gas pressure requirement, must possess the performance of pressure-resistant seal in instrument.
Existing horn antenna; Antenna size can be done greatlyyer, and the ability that receives echo-signal is strong, and it is also good that the process of metal material connects withstand voltage properties; But but do not possess the corrosion-resistant characteristic; Owing to increase the technology more complicated of anticorrosive coat,, can increase the degree of difficulty of manufacturing process if still adopt original structure at horn antenna small-caliber end mounting flange.
And to the anticorrosion antenna that designs under the general corrosion property environment; Because the all-sealed structure antenna that anticorrosion material is made has determined antenna size can not do very greatly; So receive the limited in one's ability of signal, and the process connection that anti-corrosion material is processed causes withstand voltage properties also not enough.
So existing model can not satisfy under strong steam, corrosive atmosphere with pressure operate as normal.
The utility model content
For overcoming the problem that exists in the prior art, the utility model provides a kind of anticorrosion resistance to compression type horn antenna, comprises four big parts such as oscillator, horn-like antenna, anticorrosive coat and flange.The maximum difference of this horn antenna and prior art is to adopt flange underlying mode; It is the process connected mode that flange places the loudspeaker below; Horn antenna is connected with Devices to test, and in the inboard of horn antenna and the lower surface inside lining anti-corrosive material of flange, this technological improvement can make horn antenna outside keeping the original technique characteristic; Simultaneously can satisfy the corrosion-resistant requirement, and be easy to processing.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of anti-corrosion type antenna is characterized in that, comprises a flange, and said antenna is a horn antenna, and horn antenna is connected with flange, and horn antenna inner surface and flange lower surface are provided with anticorrosive coat.
Said flange places the heavy caliber end of horn antenna.
Said anticorrosive coat is attached to the inner surface and the flange lower surface of horn antenna through the mode of fitting or spray.
Said anticorrosive coat adopts the anti-corrosion material of low-k.
Said horn antenna also comprises an oscillator, is positioned at said horn antenna small-caliber end center.
Said oscillator material is PTFE or PP or PE or F46.
Said flange is a metal flange.
Said horn antenna material is aluminium alloy or metal.
Flange is fixedly connected horn antenna with Devices to test.
In sum, the anti-corrosion type horn antenna that the utility model provides, its anticorrosive coat is when effectively protection guarantees that antenna does not receive the strong acid and strong base corrosion, its advanced low-k materials does not influence the transmission and the reception of signal yet; The horn antenna structure of flange underlying, its inner surface (face that promptly contacts with Devices to test internal corrosion property gas) structure is uncomplicated, is easy to add anticorrosive coat, and the connection of flange form process can be resisted bigger pressure, convenient disassembly; Horn antenna heavy caliber size can guarantee environment causes the situation of decay to electromagnetic wave signal under, still can effectively assemble and receive signal; Compared with prior art; The utility model has stronger adaptability to complex working condition; When guaranteeing signal receiving strength, satisfy anticorrosion, measuring body condition, and be easy to processing.

Embodiment
Combine accompanying drawing that the utility model is described further through specific embodiment below.
Fig. 1 partly cuts open figure for the horn antenna structure of available technology adopting flange mounting means, and flange is positioned at the horn antenna top.The antenna size of this structure can be done greatlyyer, and the ability that receives echo-signal is strong, withstand voltage, but does not but possess the corrosion-resistant characteristic.Simultaneously, because of the junction of flange small-caliber end, the processing of this end has also been increased difficulty at horn antenna.
Fig. 2 partly cuts open figure for the structure of the utility model horn antenna, adopts flange underlying mode.As shown in Figure 2, it is horn-like that antenna is processed heavy caliber by aluminium alloy or metal, plays the concentrated effect that transmits and receives electromagnetic, strengthens electromagnetic transmission and receive signal; The osculum central authorities of this horn antenna 2 are provided with oscillator 1, are responsible for sending and receiving electromagnetic wave, and the material of oscillator 1 can be selected PTFE, PP, PE and F46 etc. for use; Inner surface, oscillator 1 outer surface and flange lower surface at horn antenna 2; Be covered with the anticorrosive coat 3 that one deck is processed by anti-corrosion materials such as PTFE, F46; Be that the mode of fitting applies in the present embodiment; Those skilled in the art also can wait other modes to increase anticorrosive coat 3 through spraying, and the utility model is not as limit; The big opening end of horn antenna 2 is connected with flange 4, and flange places the loudspeaker below, and horn antenna is fixedly connected on the Devices to test, carries out the level gauging to material in the Devices to test.
