Description
Technical field
The utility model relates to a kind of sampler, relates in particular to a kind of coal fines sampling apparatus, belongs to the coal dust sampling technique field in pulverized coal preparation system negative pressure production run.
Background technology
Coal fines sampling apparatus is one of common instrument in pulverized coal preparation system, coal dust sampling craft device of the prior art is arranged on the flapper bottom of pulverized coal preparation system bagroom, coal dust sampling mode is by handle constantly rotation back and forth, by the coal dust in flapper lower pipeline progressively by rotary screw coal powder collection in sampling jar, then opening ball valve take out pulverized coal sample; Be 30 minutes each sample time.Pulverized coal preparation system is shut down at ordinary times, coal dust is easy to absorb airborne moisture, moist coal dust is easily bonded in the surface of screw rod, cause rotary screw to move, it is very difficult that operating personnel take out pulverized coal sample, cannot reflect accurately, in time the actual value of pulverized coal water content, make troubles to the technological operation of pulverized coal preparation system; And mostly complex structure of sampler of the prior art, causes pollution in various degree to environment in on-the-spot use, and therefore, a kind of new sampler of exigence solves above-mentioned technical matters.
Summary of the invention
The utility model is just for the technical matters existing in prior art, a kind of simple in structure, easy to operate coal fines sampling apparatus is provided, sampler of the present utility model is ingeniously on technique basis to utilize coal dust deadweight not changing, enter casing by increasing special-purpose taking powder sleeve fork, make coal dust enter stopple coupon, by the coal dust in stopple coupon being guided to precalculated position after pull-out solid handle; By solid handle Rotate 180 degree, the coal dust that makes to leave in stopple coupon falls in coal powder collection tank again; The vent ball valve of opening on coal powder collection tank is got coal.
To achieve these goals, the technical solution of the utility model is as follows, a kind of coal fines sampling apparatus, it is characterized in that, described sampler comprises illiteracy cylinder, in described illiteracy cylinder, is provided with solid handle, the described upside that covers cylinder is provided with gets powder sleeve pipe, downside is provided with holding tank, in described illiteracy cylinder, is also provided with stopple coupon, and described stopple coupon is arranged on a side of solid handle.This technical scheme one-piece construction is simple, and cost is lower, and design cleverly, by the coal dust guiding precalculated position in stopple coupon, has further guaranteed efficiency and the accuracy of sampling by pull-out solid handle.
As a kind of improvement of the present utility model, the described upside that covers cylinder is also provided with switching spiral head, guarantees that coal dust enters holding tank smoothly.
As a kind of improvement of the present utility model, the described downside that covers cylinder is also provided with the first ball valve, and described the first ball valve communicates with holding tank, is convenient to the sampling of coal dust.
As a kind of improvement of the present utility model, under described holding tank, be also provided with the second ball valve, be convenient to the sampling of coal dust.
1), whole apparatus structure is simple with respect to prior art, the beneficial effects of the utility model are as follows:, cost is low; Volume is little, maintenance operation is convenient, reliable operation; 2) this technical scheme reduces site environment and pollutes, 3) this technical scheme has improved work efficiency greatly, and reduced to 5 minute from original 30 minutes sample time, saves the working time, reduces working strength.
