Abstract
The utility model discloses a coal power sampler, belonging to a negative pressure suction type isokinetical sampler. The utility model is mainly used for the coal power sampling and flying ash sampling in the process of pneumatic conveying process. The utility model adopts two-stage cyclone separators 2 and 5, the two-stage cyclone separators 2 and 5, a bag dust remover 5 and a rotameter 7 are installed in a heat insulation type box body 19, and the internally arranged components are heated. The coal power sample which has the advantages of good separating effect, high sampling precision and safe use is more suitable for the requirement of practical application.
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.
Prior art (patent No.: the 95222029.6) sampler of Sheng Chaning, as shown in Figure 1.Mainly form, be placed on the trolley 9 by stopple coupon 1, cyclone separator 2, sampling jar 3, connecting pipe 4, sack cleaner 5, spinner-type flowmeter 6, variable valve 7, suction fan 8, well heater 12, thermometer 13, temperature controller 14, stop valve 16 and vacuum table 17.It is fast that this sampler has been eliminated dewfall, good separating effect, firing rate.But when reality was used, after coal powder density became big suddenly or extends sample time, the coal dust that enters cyclone separator increased, the separating effect variation, and coal dust easily causes cloth bag to stop up, and influences sampling precision.Moreover, be installed at the resistance type heater that sack cleaner, spinner-type flowmeter are placed outward, in use just in case temperature control may bring unsafe factor.
The purpose of this utility model is: provide a kind of separating effect better, and the coal dust sampler of safety and reliability, thus improve sampling precision, also more can be fit to the needs of practical application.
The purpose of this utility model is achieved in that one is to adopt secondary to separate to the sampling coal dust.Promptly between cyclone separator and cloth bag separator, go here and there again and increase primary separator, the sampling coal dust is after secondary separates, separation efficiency improves greatly, overcome since coal powder density becomes suddenly big or the sample time lengthening after, the shortcoming that separating effect reduces, thereby reduce the bonding of coal dust, guaranteed sampling precision cloth bag.The 2nd, the resistance type heater of cancellation sack cleaner and spinner-type flowmeter, I and II cyclone separator, sack cleaner, spinner-type flowmeter etc. are installed in the casing with heat-blocking action, the exhaust of suction fan is inserted casing with pipeline, warm exhaust when utilizing suction fan to bleed feeds casing, each parts is heated, compare, can reach the temperature difference that reduces between coal pipe and sampler equally with resistance type heater, avoid the effect of dewfall, but in when work safety and reliability.
The utility model compared with prior art, its advantage is: high score is from the two stage cyclone separation vessel (separation efficiency reaches more than 99%) of effect, makes that basic coal dust free can glue on the cloth bag, guarantees sampling precision; Cancellation part resistance type heater, the warm exhaust when utilizing the work of suction fan motor is heated to parts such as cyclone separator, sack cleaner, spinner-type flowmeters, has increased safety in utilization.
Description of drawings:
Fig. 1 is the structural representation of coal dust sampler of the prior art.
Fig. 2 is the structural representation of the utility model coal dust sampler.
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, primary cyclone 2, sampling jar 3, connecting pipe 4, secondary cyclone 5, sack cleaner 6, spinner-type flowmeter 7, variable valve 8, suction fan 9, well heater 12, thermometer 13, vacuum table 14, stop valve 16, temperature controller 17, suction fan gas outlet 18, heat-insulating type casing 19 and dolly 20 as shown in Figure 2.Connecting pipe 4 is linked in sequence stopple coupon 1, primary cyclone 2, secondary cyclone 5, sack cleaner 6, spinner-type flowmeter 7, suction fan 9, and primary cyclone 2, secondary cyclone 5, sack cleaner 6, spinner-type flowmeter 7 are placed in the heat-insulating type casing 19.Come control heater 12 by temperature controller 17; Utilize suction fan gas outlet 18 that the warm exhaust of suction fan 9 is fed in the heat-insulating type casing 19, build-in components is heated.
Before the sampling, open well heater 12 earlier, open suction fan 9, sampler is carried out preheating, after the sampler temperature reaches setting value, close well heater, be incubated, guarantee that dewfall does not take place the coal dust sampler by the warm exhaust of suction fan 9.With the contrary coal dust direction of stopple coupon 1 opening, the sample tap on the pulverized coal channel 10 11 is inserted power transportation pipe 10 middle parts then, take a sample.Like this, I and II cyclone separator 2,5, sack cleaner 6, spinner-type flowmeter 7 grades can be under no dewfall state operate as normal, both guaranteed sampling precision, improved security again.
Claims (2)
1, a kind of coal dust sampler: have stopple coupon, cyclone separator, sampling jar, connecting pipe, sack cleaner, spinner-type flowmeter, variable valve, suction fan, be positioned on the trolley, it is characterized in that: at cyclone separator 2 and 6 increase cyclone separators 5 of sack cleaner; Cyclone separator 2, cyclone separator 5, sack cleaner 6, spinner-type flowmeter 7 are installed in the heat-insulating type casing 19.
2, coal dust sampler according to claim 1 is characterized in that: the gas outlet 18 of suction fan 9 feeds heat-insulating type casing 19.
