Technical field:
This utility model relates to sensor technical field, a kind of portable dust detector.
Background technology:
In prior art, the blast furnace raw gas gone out from iron making blast furnace top row, through gravitational precipitator, big dust particle is separated, again by sack cleaner by fine powder dedusting, blast furnace gas at this moment is purified gas, and now purified gas still has the pressure of more than 120KPa, temperature more than 100 DEG C, give coal gas electricity-generating system, by this part utilization of energy, reach the purpose of energy-conservation of consumption reduction.Giving electricity generation with gas waste pressure device and have higher requirement to purified gas, purified gas dustiness requires that if concentration is the highest, the impeller of electricity generation with gas waste pressure device quickly by the dust erosion failure in purified gas, has a strong impact on normal power generation less than 10mg/m3.Therefore it is highly desirable on the purified gas pipeline before entering electricity generation with gas waste pressure device probe is installed, current signal is converted to for dust value, process through circuit amplification and data and export a dust value again, realize the function of the size of monitoring dust value, thus ensure the normal use of electricity generation with gas waste pressure device.
At present, this type of probe is usually directly welding or by being bonded on probe cassette or probe socket, it is then attached to need on the equipment of detection, it removes and installs trouble, and outside unprotected device, it is easily damaged, and it also needs to after installing and controls main frame etc. and set backup control line and be connected, just can detect etc. after whole installations, when later stage need not detection, dismounting bothers very much, not only need to disassemble probe, also need to all dismantle control line etc., very time-consuming, and it is inconvenient, this type of installs on the equipment being usually applicable to use for a long time, portable test cannot be realized.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of portable dust detector is provided, guide duct can directly be connected on the pipeline needing detection by it, can detect, it is easy to detect, and can directly take away after having detected and be connected at another detect, its detection is flexibly, good portability, it is not necessary to install for a long time, very convenient.
This utility model solves the scheme of described technical problem:
A kind of portable dust detector, including detecting head and casing, one sidewall upper articulation of described casing has case lid, casing is fixed with control main frame, centrifugal blower, accumulator, LCDs it is fixed with on case lid, charging connection head, display lamp and switch, LCDs, charging connection head, display lamp, centrifugal blower, accumulator and switch are electrically connected with the control mainboard being fixed with in control main frame by connecting line, the air intake of centrifugal blower has connected guide duct, the air intake of guide duct stretches out casing, the outlet air end of centrifugal blower connects the air vent having on the side plate of casing, it is fixed with protective cover on the side plate of casing, protective cover covers air vent, detecting head it is fixed with on guide duct, the detection bar of detecting head stretches in guide duct.
The air intake of described guide duct is bolted with prolongation connecting tube, and the outer end extending connecting tube is fixed with elastic covering.
Described elastic covering is tubaeform cover body.
Being fixed with connection frame on the medial wall of described casing, accumulator is clamped between connection frame and the medial wall of casing.
The air intake of described guide duct stretches out the front side board of casing, and disposed at air vent, in the right plate of casing, connects frame and is fixed on the left plate of casing, controls main frame and is fixed on the left plate of casing.
The top end face of described casing has upwardly extending frame-type extension, and frame-type extension is corresponding with the frame-type groove that the bottom surface of case lid has.
Described LCDs, charging connection head, display lamp and switch all stretch out the end face of case lid.
Prominent effect of the present utility model is:
Compared with prior art, guide duct can directly be connected on the pipeline needing detection by it, can detect, it is easy to detect, and can directly take away after having detected and be connected at another detect, and its detection is flexibly, good portability, it is not necessary to install for a long time, very convenient.

Detailed description of the invention:
nullEmbodiment，See as shown in Figures 1 to 4，A kind of portable dust detector，Including detecting head 10 and casing 20，One sidewall upper articulation of described casing 20 has case lid 30，Casing 20 is fixed with control main frame 1、Centrifugal blower 2、Accumulator 3，LCDs 31 it is fixed with on case lid 30、Charging connection 32、Display lamp 33 and switch 34，LCDs 31、Charging connection 32、Display lamp 33、Centrifugal blower 2、Accumulator 3 and switch 34 are electrically connected with the control mainboard being fixed with in control main frame 1 by connecting line，The air intake of centrifugal blower 2 has connected guide duct 5，The air intake of guide duct 5 stretches out casing 20，The outlet air end of centrifugal blower 2 connects the air vent 21 having on the side plate of casing 20，Protective cover 4 it is fixed with on the side plate of casing 20，Protective cover 4 covers air vent 21，Detecting head 10 it is fixed with on guide duct 5，The detection bar of detecting head 10 stretches in guide duct 5.
Further, the air intake of described guide duct 5 is bolted with prolongation connecting tube 6, and the outer end extending connecting tube 6 is fixed with elastic covering 7.
Further, described elastic covering 7 is tubaeform cover body.
Further, the medial wall of described casing 20 being fixed with connection frame 22, accumulator 3 is clamped between connection frame 22 and the medial wall of casing 20.
Further, the air intake of described guide duct 5 stretches out the front side board of casing 20, and air vent 21 is in the right plate of casing 20, connects frame 22 and is fixed on the left plate of casing 20, controls main frame 1 and is fixed on the left plate of casing 20.
Further, the top end face of described casing 20 has upwardly extending frame-type extension 23, and frame-type extension 23 is corresponding with the frame-type groove 301 that the bottom surface of case lid 30 has.
Further, described LCDs 31, charging connection 32, display lamp 33 and switch 34 all stretch out the end face of case lid 30.
Case lid 30 is connected by snap close with casing 20.
Operation principle: prolongation connecting tube 6 and the elastic covering 7 of this casing 20 are stretched in connection pipe body to be detected, then, (switch 34 has two to open all switches 34, one is on power supply, one is on centrifugal blower 2), thus open centrifugal blower 2, after centrifugal blower 2 is opened, the air with dust in cavity connection pipe body being connected sucks in guide duct 5, after the detection bar of the detecting head 10 in guide duct 5 detects dust, flow to control the control mainboard in main frame 1 by detection signal, control, after mainboard carries out data analysis, by connecting line, detection data are flowed to LCDs 31 to show, so that people can see data the time, now, display lamp 33 always light yellow, the energising of explanation equipment all goes well.
But after having detected at one, closing switch 34, insert connection pipe body to be detected at another after prolongation connecting tube 6 and elastic covering 7 being extracted from connection pipe body to be detected and can carry out subsequent detection, it is easy to detect.
And when needing charging, the dust cap 321 in charging connection 32 is opened, charging wire is connected charging connection 32, it is achieved charging.
Detecting head 10 in the present embodiment, for disclose product, no longer describes in detail.
In the present embodiment, after its casing 20 and case lid 30 cover, its size reaches 35CM length x16CM width x height 20CM, and the overall length extending connecting tube 6 and elastic covering 7 is 20CM, and its volume is little, is convenient for carrying.
