Abstract
The utility model relates to a novel handheld raw coal sampling device which comprises a sample bin with a cone-shaped head part, wherein a guide rail is arranged on the sample bin along the axis direction; a sealing cover plate capable of sliding back and forth along the guide rail is arranged on the guide rail; a positioning block for positioning the travel of the sealing cover plate is arranged at each of the front end and the rear end of the guide rail. The novel handheld raw coal sampling device can improve the sampling precision and has the advantages of simple structure, convenience in operation and the like. On the basis of the original sampling device, the sliding sealing cover plate is additionally arranged and can freely slide in front of and behind the sampling device to realize opening and closing of the sample bin, so that the sampling device can conveniently take raw coal samples at any appointed positions, and the sampling precision is obviously improved. At present, the novel handheld raw coal sampling device is successfully applied to raw coal sampling for generator sets of multiple thermal power companies, and extracted sample data are accurate and reliable.
Description
Technical field
The utility model relates to the technical fields such as electric power, coal, chemical industry, especially a kind of novel hand-held raw coal sampling device.
Technical background
Along with national energy-saving reduces discharging progressively implementing of policy, the performance index relevant to fired power generating unit are subject to electricity power enterprise and more and more pay attention to.In general, send out net coal consumption rate for evaluating the most important index of electricity power enterprise's energy conservation, its concrete numerical value mainly calculates by thermal test aggregation of data such as boiler, steam turbines, and influence factor is more.Wherein, whether coal, ash, slag sampling be accurately for affecting one of key factor of result of calculation.
In thermal test, raw coal sampling position is generally positioned at below coal bunker, the coal unloading tube section before feeder (general thermoelectricity and group are got coal mouth in this Position Design), but owing to considering the reasons such as sealing, therefore near getting coal mouth, some raw coal cannot flow, in stagnation state.And former sampler sample bin is open, cannot guarantee that former coal sample takes from the flow region of appointment or get near retention areas coal mouth, the former coal sample often gathering with the test same day the actual raw coal that enters boiler combustion differ greatly, this just causes analysis data and True Data to have certain deviation, the accuracy of impact test and result of calculation.Therefore, the former coal sample that how to make sampler collection is the former coal sample of duration of test burning, for increase test accuracy, measurement effects of energy saving and emission reduction, has great importance.
Utility model content
The utility model relates to a kind of novel hand-held raw coal sampling device, and this device can effectively improve sampling precision, and has the advantages such as simple in structure, easy to operate.
The technical solution adopted in the utility model is as follows:
A kind of novel hand-held raw coal sampling device, comprise the sample bin that a head is cone, on described sample bin along being provided with a guide rail on its axis direction, described guide rail is provided with a seal cover board slidably reciprocating along it, respectively establishes the locating piece of a restriction seal cover board stroke in the rear and front end of guide rail.
The end of seal cover board vertical be provided with a handles.
The afterbody of described sample bin is provided with coupled connecting rod, at the afterbody of connecting rod, is provided with coupled operating grip.
Described cover plate is that radian is the circular arc steel plate of 180 °, and diameter is greater than the diameter of sample bin.
Described guide rail comprises longitudinal ridge and cannelure, and described longitudinal ridge is welded on sample bin outside along the longitudinal direction of sample bin, and described cannelure is welded on seal cover board circular arc inner side along the longitudinal direction of seal cover board.
Before and after guide rail longitudinal ridge, be respectively welded with a positioning block, so that accurately control the moving range of seal cover board.
Use procedure of the present utility model is as follows:
1) under the state of raw coal sampling device being closed at seal cover board, insert coal unloading tube center assigned address; 2) open seal cover board, the former coal sample in flow state falls into sample bin; 3) close seal cover board, extract raw coal sampling device; 4) former coal sample sample bin being collected is taken out and is completed sampling.
The beneficial effects of the utility model are as follows:
Operator can avoid obtaining near the raw coal being previously detained sample tap in sampling process, guarantees that the sample of sampler collection is for entering at once the raw coal of boiler combustion, thereby effectively improves the sampling precision of sampler.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of novel hand-held raw coal sampling device, comprise the sample bin 3 that a head is cone, on described sample bin 3 along being provided with a guide rail 4 on its axis direction, a locating piece 2 is respectively established at the two ends of described guide rail 4, and described guide rail 4 is provided with a seal cover board slidably reciprocating along it 5, the end of seal cover board 5 vertical be provided with a handles 7.
Described cover plate is that radian is the circular arc steel plate of 180 °, and diameter is greater than the diameter of sample bin.
Described guide rail comprises longitudinal ridge and cannelure, and described longitudinal ridge is welded on sample bin outside, and described cannelure is welded on seal cover board circular arc inner side, and longitudinal ridge, groove combination can realize mutual relative motion.
Before and after guide rail longitudinal ridge, be respectively welded with a positioning block, be convenient to accurately control the moving range of seal cover board.
The end of described connecting rod is provided with an operating grip.
The utility model has increased slipper seal cover plate on the basis of former sampler, this cover plate materials is 180 ° of circular arc steel plates, circular arc inner side, two ends is designed with cannelure, can on guide rail, slide front and back, rely on locating piece to control sliding scale, accurately to realize the open and close of sample bin, so can make the convenient former coal sample of any given position that gathers of sampler device, significantly improved sampling precision.
Sampler main operational steps is: so, operator can avoid obtaining near the raw coal being previously detained sample tap in sampling process, guarantee that the sample of sampler collection is for entering at once the raw coal of boiler combustion, thereby effectively improve the sampling precision of sampler.At present, this device has been successfully applied to the raw coal sampling work of Duo Jia thermoelectricity company genset, extracts sample data accurately, reliably.
