The volute coal powder sampling device comprises a sampling part and a feeding part according to the technical scheme provided in the invention; the invention is characterized in that the sampling part is provided with a sampling pipe, and the cross section of the sampling pipe is volute-shaped; the feeding part is provided with an auger, the inner end of the auger is the sampling pipe, a shaft of the auger stretches out of the outer end of the auger, and the outer end of the auger is provided with an interface connected with a sampling bottle. The invention can improve the sampling efficiency and reduce the environmental pollution.
Description
Technical field
The present invention relates to a kind of coal handling plant that is used for the generating plant, refer in particular to a kind of spiral casing type coal fines sampling apparatus.
Background technology
It is the bottom-up flow system powder system of breeze airflow that coal fines sampling apparatus is mainly used in the power station direct-firing.Coal cinder is through pulverizing and following the hot blast medium to enter separation vessel and separate, and the qualified coal dust after the separation is by coal fines sampling apparatus grab sample and censorship.The used stopple coupon of existing coal fines sampling apparatus is the pipe shape, and the setting of its sample tap is unfavorable for sampling; And whole sampling process does not have strict seal approach, and is therefore more serious to the damage ratio of environment.
Summary of the invention
The objective of the invention is to design a kind of spiral casing type coal fines sampling apparatus,, reduce environmental pollution to improve sampling efficiency.
According to technical scheme provided by the invention, described spiral casing type coal fines sampling apparatus comprises sampling part and transport portion, it is characterized in that: stopple coupon is arranged in sampling part, and the transversal section of stopple coupon is scroll casing shape; Flood dragon is arranged in transport portion, and the inner of flood dragon is positioned at stopple coupon, and the shaft extension of flood dragon goes out the outer end of flood dragon, is provided for connecting the interface of sampling jar in the outer end of flood dragon.
Lower end at interface connects the sampling jar that is interconnected, and the operation valve of on-off action has been set on interface.Have the rectangle sample tap on the stopple coupon, this sample tap is along the tangential direction of scroll casing shape stopple coupon; Described flood dragon is positioned at the center of scroll casing shape stopple coupon.Handle is installed in outer end at axle, in the end of the close handle of flood dragon sealing socket is arranged, and between sealing socket and flood dragon and axle thereof airtight and watertight padding is arranged.
Advantage of the present invention is: 1, the shell of stopple coupon adopts the spiral case form, utilizes cyclonic principle that coal dust is entered in the housing, reaches the effect of collecting coal dust.2, collect coal dust work and all under full closeding state, carry out, prevent the excessive and unrestrained of coal dust, clean environment firendly.3, coal dust is taken out by handle rotation by flood dragon, and is easy and simple to handle, saves time, laborsaving, accurate.4, easy accessibility detachably gets off when not using, and maintenance does not influence the coal dust operation in the pipeline simultaneously easily yet.Rational in infrastructure, weight is little.
Description of drawings
Fig. 1 is user mode figure of the present invention.
Fig. 2 is the A-A view among Fig. 1.
Embodiment
As shown in the figure: described spiral casing type coal fines sampling apparatus comprises sampling part and transport portion, and stopple coupon 1 is arranged in sampling part, and the transversal section of stopple coupon 1 is scroll casing shape; Flood dragon 2 is arranged in transport portion, and the inner of flood dragon 2 is positioned at stopple coupon 1, and axle 8 outer ends of stretching out flood dragon 2 of flood dragon 2 are provided for connecting the interface 10 of sampling jar 4 in the outer end of flood dragon 2.The inner sealing of stopple coupon 1 is stopped up, so that flood dragon 2 is taken out the coal dust sample in the stopple coupon 1.
Lower end at interface 10 connects the sampling jar 6 that is interconnected, and the operation valve 5 of on-off action has been set on interface 10.When beginning to take a sample, just open operation valve 5, when stopping sampling, in the time of need taking off sampling jar 6, must closed control valve 5.Have rectangle sample tap 9 on the stopple coupon 1, this sample tap 9 is along the tangential direction of scroll casing shape stopple coupon 1, and described flood dragon 2 is positioned at the center of scroll casing shape stopple coupon 1, so that coal dust enters in the flood dragon 2 smoothly.
When installing with use:
1, determines the installation site of spiral casing type coal fines sampling apparatus on pulverized coal feed pipe 11 earlier.
2, leave hole 12 according to the size of pulverized coal feed pipe 11, the pore size in hole 12 can be referring to accompanying drawing.In the time of need not taking a sample, this sampler should be taken off, with pipe plug seal bore 12.
3, insert this sampler, notice that the sample tap 9 of stopple coupon 1 should align the breeze airflow direction, be beneficial to capture coal dust, see shown in the arrow among Fig. 1.
Rotation direction when 4, auger 2 is rotated counterclockwise to sampling.When sampling, should note auger 2 rotation directions, to guarantee that pulverized coal flow is in sampling jar 6.
When 5, taking a sample, at first will turn clockwise several weeks, cleaning residues in the outmoded coal dust in the sampler, and then begins normal sampling work, to guarantee obtaining fresh coal dust at every turn at every turn.During sampling, the rotating speed of auger 2 is wanted fast.
6, when sampling, still to effluxing powder, cause unnecessary fault after noting in sampling jar 6, not being full of coal dust.
7, when getting sampling jar 6, first closed control valve 5, in order to avoid contaminated environment.
Airtight and watertight padding 4 (being graphite annulus) in will making regular check on and change auger 2 outer end sealing sockets 7 at ordinary times.Check that simultaneously operation valve 5 has or not latch up phenomenon, the aperture of operation valve 5 is placed suitable position.
