Brief description of the drawings
Fig. 1 is a kind of structural representation of economizing type radar stock rod.
Fig. 2 is a kind of cross-sectional structural representation of connecting tube in economizing type radar stock rod.
In figure：Radar stock rod gauge outfit 1, PLC controlling organizations 2, flange 3, lens 4, nitrogen inlet A5, nitrogen inlet B6, company
Adapter 7, ball valve 8, blast furnace 9, booster pump 10.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of economizing type radar stock rod, including economizing type radar stock rod
Body；The economizing type radar stock rod body is entered by radar stock rod gauge outfit 1, PLC controlling organizations 2, flange 3, lens 4, nitrogen
Mouth A5, nitrogen inlet B6, connecting tube 7, ball valve 8, booster pump 10 form；The radar stock rod gauge outfit 1 passes through flange 3 and connecting tube
7 are connected；The inside of connecting tube 7 is provided with lens 4, and the bottom of connecting tube is provided with ball valve 8, and ball valve 8 is connected with blast furnace 9 below
Connect, lens 4 are arranged on the inside of connecting tube 7 close to the position at top；The connecting tube 7 lens 4 opening position all around
Through hole is offered respectively, and nitrogen inlet duct road is installed in through hole；The wherein nitrogen inlet duct of the left and right sides and nitrogen inlet A5
It is connected, and booster pump 10 is installed on pipeline, booster pump 10 is built-in with PLC controlling organizations 2；Front and rear nitrogen inlet duct and nitrogen
Entrance B6 is connected；The bottom of the connecting tube 7 is connected with ball valve 8, and ball valve 8 is connected with blast furnace 9.
The PLC controlling organizations 2 are to control booster pump, and the model of PLC controlling organizations 2:PLC- Siemens S7-
200。
The lens 4 are sphere lenses and the angle of departure is less than 4 degree.
The booster pump 10 is electrically connected with by wire and external power source, and switch is in series with link circuit.
The diameter of the connecting tube 7 is less than 130mm.
Operation principle of the present utility model is：Nitrogen inlet A enter booster pump supercharging nitrogen enter pipe A reach purge it is spherical
The purpose of lens, pressure purging nitrogen inlet A is increased by changing purging structure both sides, while nitrogen inlet B is not over increasing
Press pump purges.
Nitrogen inlet A is pressurized into booster pump, and nitrogen intake air pressure is reached between 8 kilograms~17 kilograms；Make entrance with
Blast furnace internal pressure forces the pressure that difference reaches 6-15 kilograms, and PLC control booster pumps make booster pump purge 5 minutes nitrogen every 12 hours
Entrance B is blast furnace nitrogen pressure tank, is only cooled for radar lens, and so total dosage of nitrogen can be little, and due to high pressure nitrogen energy
Strength cleans lens.Which reduces the time of nitrogen purging, cost is reduced.
It is less than 4 ° (electromagnetic horn is generally 7 ° -14 °) from sphere lenses and the lens angle of departure, it is small so connects pipe diameter
In 130mm, be advantageous to purge, and ball valve diameter is less than 130mm.So the diameter of ball valve will be small.So flange is to blast furnace
Height will diminish, and be advantageous to material height in more accurate measurement blast furnace.
Ball valve is only needed to close can maintenance when needing and overhauling radar stock rod.
