The coal ash sampler that current state's electricity fuel-burning power plant uses has a variety of, and all deposit problem in the following areas during use: stifled grey plugging is serious, wearing and tearing are comparatively serious, sometimes do not collect ash sample, have influence on the analysis of power plant to coal sample.
Summary of the invention
The purpose of this utility model is intended to the plugging of solution existing for prior art, the technical barrier of wearing and tearing, hidden arm-type design is adopted will effectively to solve short problem in serviceable life, make power plant can sample analysis coal ash at any time in boiler operatiopn, for realizing boiler combustion optimization, provide effective credible means, meet the needs of on-the-spot actual production process well.
Technical solution of the present utility model: full-automatic coal ash sampler, its structure comprises thief rod 1, sampling jar 2, cyclone dust collector 3, articulation 4, draft tube 5, electrical ball valve (gas admittance valve) 6, pressure regulator valve 7, stream-jet ejector 8, electrical ball valve (blow down valve) 9, sampling operation bar 10, electrical ball valve 11, topworks 12; Wherein topworks 12 and mounting flange 13 are fixed on pipeline, and topworks 12, sample valve 11, gas admittance valve 6, blow down valve 9 connect with single chip control unit 14 respectively.
Advantage of the present utility model:
(1) structure is simple, samples simple and convenient;
(2) pressurized air is adjustable, and the coal dust sample of taking-up is representative;
(3) pressurized air can be adopted to purge stopple coupon, avoid coal dust to block stopple coupon;
(4) be fixedly mounted on pulverized coal channel, seal tight, none leakage of pulverized coal, does not pollute working environment;
(5) insert in pulverized coal channel when stopple coupon uses, can exit outside pulverized coal channel after taking coal dust sample, avoid washing away of breeze airflow, long service life;
(6) one people can operate, and labor intensity of operating staff is little;
(7) easy for installation, maintenance is little: adopt flange mounting design, adopt proprietary clogging-preventing measures, and make installation simple, maintenance work is few;

Embodiment
As shown in drawings, full-automatic coal ash sampler, its structure comprises thief rod 1, sampling jar 2, cyclone dust collector 3, articulation 4, draft tube 5, electrical ball valve (gas admittance valve) 6, pressure regulator valve 7, stream-jet ejector 8, electrical ball valve (blow down valve) 9, sampling operation bar 10, electrical ball valve 11, topworks 12; Wherein topworks 12 and mounting flange 13 are fixed on pipeline, and topworks 12, sample valve 11, gas admittance valve 6, blow down valve 9 connect with single chip control unit 14 respectively.
Described thief rod 1 is connected with topworks 12 by sampling operation bar 10;
Described sampling jar 2 is threaded connection with cyclone dust collector 3;
The top of described cyclone dust collector 3 is connected with stream-jet ejector 8 by articulation 4;
The left side of described stream-jet ejector 8 is connected with blow down valve 9 by 1/4 joint, and the right of stream-jet ejector 8 is connected with gas admittance valve 6 by 1/4 joint;
The right of described gas admittance valve 6 is connected with one end of pressure regulator valve 7; The other end of pressure regulator valve 7 is connected with manual ball valve 5 through 1/4 joint;
Described manual ball valve 5 external gas source.
During enforcement:
(1) power to operating unit, the single-chip microcomputer display unit initialization system time, start sample time and sample time length.Can arrange according to the actual requirements system time, sampling the start time and sample time length;
(2) after setting basic parameter, press operation button, triggering system is run.Single-chip microcomputer provides four road high level signals, causes the ball valve action of sampler.Simultaneity factor starts timing, when timer timing time reaches setting value, has two-way low level output, makes gas admittance valve and sample valve action, reset;
(3) time delay is after 20 seconds, in addition two-way low level, and other ball valves automatically reset.Now, sampling terminates;
(4) start after sample time when setting, when system time arrives this moment, system can automatic sampling, and separated in time terminates sampling;
Wherein: when manually pressing operation button, sampled functions immediately can be realized.
Of the present utility model effectively solve plugging and wearing and tearing two large technical barriers, achieve non-maintaining, make power plant can sample analysis coal ash at any time in boiler operatiopn, for realizing boiler combustion optimization, provide effective credible means, meet the needs of on-the-spot actual production process well.
