The utility model discloses the sample is even, sealed effectual.
Description
Technical field
The utility model relates to a kind of sampler, specifically station boiler fly ash sampling device.
Background technology
Station boiler in order to calculate boiler efficiency and combustion adjustment, unburned carbon in flue dust to be measured, it is necessary to flying dust is sampled, use
Fly ash sampling device.In current fly ash sampling device, being commonly present uneven, the ash sample of sampling does not has representativeness, causes calculating inaccurate or runs
Instructing deviation, some sealing effectiveness are bad, cause and leak out, and add heat loss due to exhaust gas.The present invention preferably solves the problems referred to above, practical.
Summary of the invention
A kind of station boiler fly ash sampling device that the utility model is invented, overcome tradition sampler sample point few, sampling lack representativeness,
The problems such as probe tube easily blocks, leak out, have sampling uniformly, good sealing effect, practical.
The utility model solves the technical scheme of technical problem: it is characterized in that including probe tube, boatswain chair, sealing offset plate, davit, lower boatswain chair,
Supporting plate, rubber cushion, sampling bottle, screw rod, handwheel, probe tube is fixed on below the flue below air preheater, is provided with valve on probe tube, sampling
Pipe lower end is fixed with boatswain chair, is fixed with four isometric davits, seals offset plate, be fixed with lower boatswain chair in davit lower end, on lower boatswain chair below boatswain chair
Face is sequentially installed with supporting plate, rubber cushion, sampling bottle, is fixed with screw rod below supporting plate, and screw rod is connected by spiral with lower boatswain chair, lower end is provided with hand
Wheel, screw rod can drive supporting plate to move up and down sampling bottle by rotation, and probe tube top seals, upper end puts in the middle part of flue, meets cigarette side and has multiple little
Hole, for taking flying dust.Flying dust in flue enters probe tube by the hole on probe tube top, when taking ash, rises sampling bottle, and bottleneck is facing to sealing
The mouth of offset plate, opens valve, and ash is i.e. dropped in bottle, takes after ash completes, closes valve, take sampling bottle away, and rise supporting plate, make rubber cushion and sealing
Offset plate engages, avoids leaking out.
What the utility model was had actively has the beneficial effect that taken ash sample is uniform, representative, and ash sample after analysis can be for boiler operatiopn
Instruct, firing optimization and calculate provide accurate foundation, do not result in simultaneously leak out, good sealing effect.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention
Fig. 2 is the A-A sectional view of the present invention.
Detailed description of the invention
A kind of station boiler fly ash sampling device, it is characterised in that include probe tube 8, boatswain chair 7, seal offset plate 11, davit 6, lower boatswain chair 3,
Supporting plate 4, rubber cushion 5, sampling bottle 12, screw rod 2, handwheel 1, probe tube 8 is fixed on below the flue 9 below air preheater, pacifies on probe tube 8
Equipped with valve 10, probe tube 8 lower end is fixed with boatswain chair 7, is fixed with four isometric davits 6, seals offset plate 11, at davit 6 below boatswain chair 7
Lower end is fixed with lower boatswain chair 3, is sequentially installed with supporting plate 4, rubber cushion 5, sampling bottle 12, is fixed with screw rod 2 below supporting plate 4 on lower boatswain chair 3,
Screw rod 2 is connected by spiral with lower boatswain chair 3, lower end is provided with handwheel 1, and screw rod 2 can drive supporting plate 4 to move up and down sampling bottle 12 by rotation,
Probe tube 8 top seals, upper end puts in the middle part of flue 9, meets cigarette side and has multiple aperture, for taking flying dust.Flying dust in flue passes through probe tube
The hole on 8 tops enters probe tube, when taking ash, rises sampling bottle 12, and bottleneck, facing to the mouth of sealing offset plate 11, opens valve 10, and ash is i.e. dropped into
In sampling bottle, take after ash completes, close valve 10, take sampling bottle 12 away, and rise supporting plate 4, make rubber cushion 5 engage with sealing offset plate 11, keep away
Exempt to leak out.
