Abstract
The utility model discloses a coal powder sampler which belongs to a negative pressure suction type isokinetical sampler. The utility model is mainly used for the coal powder sampling and the flying ash sampling in the process of pneumatic conveying. Heaters (12) are respectively arranged on a connection tube (4) arranged between a sampling tube (1) and a cyclone separator (2), a bag dust remover (5) and a rotameter (6). An airflow inlet of the bag dust remover (5) is arranged at the lower part and the airflow outlet is arranged at the upper part. The lower end of the bag dust remover (5) is provided with a funnel type second stage sample connection (15). The coal power sampler has no moisture condensation, good separation effect, high measuring accuracy, and sampling accuracy improvement due to two stages of separation and sampling. The practical application requirement can be met.
Description
The utility model relates to a kind of coal dust sampler, belongs to the negative pressure suction type isokinetical sampler, is mainly used in coal dust sampling and Fly ash sampling in the process of pneumatic transmission.
In the prior art, a kind of coal dust sampler that MIT produces, as shown in Figure 2.Mainly form, be placed on the trolley 9 by stopple coupon 1, cyclonic separation 2, sampling jar 3, connecting pipe 4, sack cleaner 5, spinner-type flowmeter 6, variable valve 7 and suction fan 8.During sampling, the contrary pulverized coal flow direction of stopple coupon 1 opening by the sample tap on the power transportation pipe 10 11, is inserted power transportation pipe 10 middle parts.This sampler is pressed ASTM (U.S. material and test association) standard manufacture, good separating effect, measuring accuracy height.But when reality was used, because the pulverized coal flow water percentage is higher, dewfall was serious, and stopple coupon is stopped up, and the separation efficiency of cyclonic separation descends, and spinner-type flowmeter sticks coal dust can't accurate measurement.In addition, pulverized coal borne air flow is entered by sack cleaner top, is extracted out by the bottom behind the cloth bag filtration, and the coal dust that accumulates in the sack cleaner is difficult to take out, and influences sampling precision, causes air-flow inhomogeneous simultaneously, even gas velocity is descended, and has increased error in dipping.
The purpose of this utility model provides a kind of no dewfall, good separating effect, and metering, the coal dust sampler that sampling precision is high are to satisfy the needs of practical application.
The purpose of this utility model is achieved in that a well heater respectively is installed on the connecting pipe between stopple coupon and cyclonic separation, on the sack cleaner and on the spinner-type flowmeter, thereby avoids moisture content separation generation dewfall in the air-flow.The airflow inlet of sack cleaner is arranged on the bottom, and air stream outlet is arranged on top, and pulverized coal borne air flow enters from the bottom and filters the back by the top extraction, and the coal dust that filters out falls into the bottom of sack cleaner.The lower end of sack cleaner is provided with the secondary sample tap, makes the coal dust that goes out through the sack cleaner secondary separation be easy to take out.
The utility model is compared the advantage that is had with existing bright technology: no dewfall, can not stop up stopple coupon, and guarantee the separation efficiency and the spinner-type flowmeter operate as normal of cyclonic separation.Coal dust free accumulates on the cloth bag of sack cleaner, and gas velocity is stable, the measuring accuracy height.Two-stage is separated sampling, has improved sampling precision.Satisfy the needs of practical application fully.
Description of drawings:
Fig. 1 is the structural representation of the utility model coal dust sampler.
Fig. 2 is the structural representation of coal dust sampler of the prior art.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Structure of the present utility model mainly is made up of stopple coupon 1, cyclonic separation 2, sampling jar 3, connecting pipe 4, sack cleaner 5, spinner-type flowmeter 6, variable valve 7, suction fan 8, trolley 9, well heater 12, thermometer 13, temperature controller 14, stop valve 16 and vacuum table 17 as shown in Figure 1.Connecting pipe 4 is linked in sequence stopple coupon 1, cyclonic separation 2, sack cleaner 5, spinner-type flowmeter 6 and suction fan 8, is positioned on the trolley 9.A resistance type heater 12 respectively is being installed on the connecting pipe 4 between stopple coupon 1 and cyclonic separation 2, on the sack cleaner 5 and on the spinner-type flowmeter 6.Three well heaters 12 are controlled by being installed in thermometer 13 on sack cleaner 5 outlet connecting pipes 4 and the temperature controller 14 on the trolley 9, manually, automatically all can, guarantee promptly not make the coal dust sampler to produce dewfall, also not spontaneous combustion of coal dust.The airflow inlet of sack cleaner 5 is arranged on the bottom, and air stream outlet is arranged on the upper end.The bottom of sack cleaner 5 is provided with funneling secondary sample tap 15.
A stop valve 16 is equipped with in the outlet of spinner-type flowmeter 6, and a vacuum table 17 is equipped with in the outlet of sack cleaner 5, constitutes the leak testing device of this coal dust sampler, has further guaranteed the precision of metering.
Before the sampling, control three well heaters 12 and all open, sampler is carried out preheating, sampler is heated up rapidly, reach setting value after, switch to keeping warm mode.With the contrary pulverized coal flow direction of stopple coupon 1 opening, by the sample tap on the power transportation pipe 10 11, insert power transportation pipe 10 middle parts, take a sample.Cyclonic separation son 2 and spinner-type flowmeter 6 operate as normal under no dewfall state.Through cyclonic separation 2 coal dusts that separate with sack cleaner 5 two-stages, the sample tap below cyclonic separation 2 and the funneling secondary sample tap 15 of sack cleaner 5 lower ends enter sampling jar 3 respectively.
Claims (2)
1. coal dust sampler, have stopple coupon, cyclonic separation, sampling jar, connecting pipe, sack cleaner, spinner-type flowmeter, variable valve and suction fan, be placed on the trolley, it is characterized in that: on the connecting pipe (4) between stopple coupon (1) and cyclonic separation (2), sack cleaner (5) upward and on the spinner-type flowmeter (6) respectively is equipped with a well heater (12), the airflow inlet of sack cleaner (5) is arranged on the bottom, air stream outlet is arranged on top, and the lower end of sack cleaner (5) is provided with secondary sample tap (15).
2. coal dust sampler according to claim 1 is characterized in that described spinner-type flowmeter (6) outlet is equipped with a stop valve (16), and cyclonic separation (2) is equipped with a vacuum table (17) between the spinner-type flowmeter (6).
