In prior art, the blast furnace raw gas of discharging from blast furnace furnace roof, through gravitational precipitator, big dust particle is separated, again by sack cleaner by fine powder dedusting, blast furnace gas is at this moment purified gas, now purified gas still has pressure more than 120KPa, be greater than the temperature of 100 ℃, give coal gas electricity-generating system, by this part energy utilization, reach the object of energy-conservation of consumption reduction.Giving electricity generation with gas waste pressure device has higher requirement to purified gas, and purified gas dustiness requires to be less than 10mg/m3, if concentration is too high, the impeller of electricity generation with gas waste pressure device is washed away damage by the dust in purified gas very soon, has a strong impact on normal power generation.Therefore be starved of probe is installed on the purified gas pipeline entering before electricity generation with gas waste pressure device, be converted to current signal for dust value, again through circuit amplification and data processing and export a dust value, realize the big or small function of monitoring dust value, thereby guarantee the normal use of electricity generation with gas waste pressure device.
At present, this type of probe generally bonds metal detection rod or is weldingly fixed in probe cassette by cementing agent, very trouble of the maintenance that it is follow-up and dismounting, the difficulty that has increased dismounting and maintenance, meanwhile, existing probe cassette is cylindrical box body, the link of its wiring is in the lid of box body, in the time opening the lid, can produce certain dilatory effect to connecting line, repeatedly dismounting can make the phenomenons such as producing loose contact that is connected between connecting line and metal bar, the effect that impact detects.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of metal bar probe cassette of novel dust detection instrument is provided, it can will be screwed onto in box body with the metal bar of coupling arrangement, for convenience detach, simultaneously, its Wiring port is on sidewall, and lid is opened to close so all can not affect the connection of connecting line effect, guarantees the normal use of equipment.
The scheme that the utility model solve the technical problem is:
A metal bar probe cassette for novel dust detection instrument, comprises probe cassette, and described probe cassette is cuboid, and the side that its structure is lid is hinged on box body by jointed shaft, and lid hamper is on box body, and the screw rod of set bolt passes lid and is screwed onto in box body;
On one sidewall of box body, form sidewall screw, Wiring port is screwed onto in sidewall screw;
The bottom surface of the base plate of box body forms the projection to downward-extension, and raised central portion forms connecting screw hole, and the top of connecting screw hole extends to the upper plane of base plate, and the bottom of connecting screw hole extends to protruding bottom face.
On the base plate of described box body, in plane, form cylinder, cylinder upper surface is bolted with screw, and cylinder is around connecting screw hole.
On the base plate of described box body, in-plane is fixed with connection fixture block by set bolt, connects fixture block in box body.
Described connection fixture block is semicircle ring block, and the semi-circular recesses at its middle part is corresponding up and down with the top of connecting screw hole.
On the bottom surface of described lid, be formed with elastic bumps limit, elastic bumps limit surrounds a closed level, and closed level sleeve is in the inner chamber body of box body, and the lateral wall elasticity on elastic bumps limit is pressed against on the madial wall of box body.
Outstanding effect of the present utility model is:
Compared with prior art, it can be by being screwed onto in box body with the metal bar of coupling arrangement, and for convenience detach, meanwhile, its Wiring port is on sidewall, and lid is opened to close so all can not affect the connection of connecting line effect, guarantees the normal use of equipment.
Accompanying drawing explanation:
Fig. 1 is the structural representation that the utility model is provided with metal detection rod;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the vertical view of box body of the present utility model.
Embodiment:
Embodiment, see as shown in Figures 1 to 3, a kind of metal bar probe cassette of novel dust detection instrument, comprise probe cassette 1, described probe cassette 1 is cuboid, its structure is that a side of lid 12 is hinged on box body 11 by jointed shaft, and lid 12 hampers are on box body 11, and the screw rod of set bolt passes lid 12 and is screwed onto in box body 11;
On one sidewall of box body 11, form sidewall screw 13, Wiring port 9 is screwed onto in sidewall screw 13;
The bottom surface of the base plate 111 of box body 11 forms the projection 114 to downward-extension, and protruding 114 middle parts form connecting screw hole 112, and the top of connecting screw hole 112 extends to the upper plane of base plate 111, and the bottom of connecting screw hole 112 extends to the bottom face of projection 114.
Like this, metal bar is fixed on adapter sleeve, and adapter sleeve is screwed onto in the connecting screw hole 112 of box body 11, and in the time that metal bar damage needs repairing, it can make metal bar dismounting and installation from connecting screw hole 112 easily, very convenient like this.Meanwhile, its Wiring port 9 is in the sidewall screw 13 of box body 11, and the Wiring port 9 that connecting line one end is fixed on the bottom of metal bar and from side screw 13 passes, and lid 12 is opened to close so all can not affect the connection of connecting line effect.
