Abstract
The utility model relates to the technical field of thermal power plant equipment, in particular to a pulverized coal sampling device of a warehouse type coal pulverizing system, which comprises a powder collection bottle, a sleeve, spiral blades and a micromotor, and the powder collection bottle, the sleeve, the spiral blades and the micromotor are connected with each other. The front section of the sleeve is arranged in a coal feeding pipe of the warehouse type coal pulverizing system, a position under the rear part of the sleeve is communicated with the powder collection bottle through a pipeline, and the spiral blades are arranged in the interior of the sleeve. The rear end of the spiral blades is connected with an output shaft of the micromotor, and long-strip-shaped openings are arranged on the upper portion and the lower portion of the section of the sleeve extending into the coal feeding pipe. The coal sampling device of the warehouse type coal pulverizing system achieves mechanized pulverized coal sampling, and has the advantages of being accurate in sampling, labor-saving and high in automation degree.
Description
Technical field
The utility model relates to a kind of electric power factory equipment technical field, specifically a kind of coal fines sampling apparatus of bin system.
Background technology
For the pulverized coal in power plant boiler; The economic fineness of coal dust is an important parameter of burning optimization; Fineness of pulverized coal is not only big but also also be important factor in order to safe operation of the boiler to performance driving economy influence; Particularly use meager coal and anthracitic boiler, the influence of fineness of pulverized coal is even more important.Because the caused harm of coal dust chap is very big, a series of problems such as wearing and tearing and the burning efficiency of boiler extinguishment, coking, high temperature corrosion, reheater overtemperature tube burst, back-end surfaces is low can take place all has direct relation with fineness of pulverized coal.Therefore, coal dust being taken a sample, is to be an indispensable job in coal-fired power plant's boiler operatiopn to fineness of pulverized coal analysis then; According to measurement result to fineness of pulverized coal; Contrast optimal economic value is suitably adjusted the operation of pulverized coal preparation system, and is significant to boiler economic operation.At present, to the hand sampling that is sampled as of coal dust, there is poor working environment in the method for hand sampling in bin system, must prolong sample time and decimation ratio if reach to sample to choose accurately, and labour intensity is big, and working routine is loaded down with trivial details, and automaticity is low.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, and mechanized operation, sampling are accurately practiced thrift manpower, the coal fines sampling apparatus of the bin system that automaticity is high.
The technical scheme that the utility model adopts is: a kind of coal fines sampling apparatus of bin system; Comprise the collection powder bottle; Also comprise sleeve pipe, helical blade and micromotor; Described sleeve pipe leading portion is arranged on the coal unloading tube inside of bin system, and the lower rear of sleeve pipe is communicated with the collection powder bottle through pipeline, and the set inside of sleeve pipe has helical blade; The rear end of helical blade is connected with the output shaft of micromotor, on section sleeve pipe of that in stretching into coal unloading tube, its upper and lower is provided with the strip opening.
The utility model is provided with helical blade in sleeve pipe, and the upper and lower of that section sleeve pipe in stretching into coal unloading tube all is provided with elongated slot, and the lower rear of sleeve pipe is communicated with the collection powder bottle; The rear end of helical blade is stretched out sleeve pipe and is connected with the output shaft of reductor, and motor via reducer can drive the positive and negative direction rotation of helical blade, when coal dust constantly falls in coal unloading tube; Coal dust can fall in the sleeve pipe from the strip opening of sleeve pipe, and the helical blade that is rotated is delivered to the collection powder bottle along sleeve pipe, realization machinery generation completion coal dust sample acquisitions; Leading portion because of sleeve pipe is that the upper and lower all is provided with the strip opening again; So in sampling process, coal dust also is sampling in sleeve pipe while falling, and belongs to sampling and chooses; Sampling is accurate, has guaranteed samples' representativeness.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model, comprises the bag powder bottle, also comprises sleeve pipe 1, helical blade 2 and micromotor 3; Motor is connected with reductor; Described sleeve pipe 1 leading portion is arranged on the coal unloading tube inside of bin system, and the lower rear of sleeve pipe 1 is communicated with the collection powder bottle through pipeline, and the set inside of sleeve pipe 1 has helical blade 2; The rear end of helical blade 2 is connected with the output shaft of micromotor 3, on section sleeve pipe of that in stretching into coal unloading tube 1, its upper and lower all is provided with the strip opening.
The utility model motor via reducer drives helical blade 2 rotations; When needing the coal dust sampling; When helical blade 2 reverse rotations, coal dust constantly fell in coal unloading tube, coal dust can fall into from the strip opening of sleeve pipe 1 in the sleeve pipe 1; And the helical blade 2 that is rotated along sleeve pipe 1 with coal dust by outwards being delivered to the collection powder bottle in the coal unloading tube, realize that mechanization accomplishes the coal dust sample acquisitions.After the coal dust sample acquisitions finished, motor drives helical blade 2 more just to be changeed, and the residue coal dust of staying like this in the sleeve pipe 1 will be transported in the coal unloading tube again, and the strip opening from sleeve pipe 1 bottom screws out then.In sampling process, because the leading portion of sleeve pipe 1 is that the upper and lower all is provided with the strip opening,, belongs to sampling and choose so coal dust also is sampling in sleeve pipe 1 while falling, sampling is accurate, has guaranteed samples' representativeness.
The utility model has been realized the sampling of mechanization coal dust, has sampling accurately, practices thrift manpower, the characteristics that automaticity is high.
