Compared with the prior art, the utility model has the advantages of it removes dust to prevent laying dust, mediation.
Description
Technical field
The utility model relates to a kind of sampler, especially relates to a kind of boiler and measures anti-blocking sampler.
Background technology
Coal-fired power plant unit boiler has a large amount of important flue gas pressures, and differential pressure, air quantity need to measure, such as: furnace pressure, coal pulverizer differential pressure, fly-ash separator pressure, differential pressure, First air flow etc., to ensure security and the economy of boiler combustion system.
As shown in Figure 3, existing boiler great majority adopt traditional sampler, there is following shortcoming:
(1), when measured medium has dust, device is easily blocked;
(2), when in device during dust stratification, high-temperature flue gas meets condensation knot, and water is consolidated with grey hybrid junctions clotting, more difficult removing;
(3) must clear up when measuring hard to carry on, when opening sealed end, high temperature cigarette or wind are scurried out and may be jeopardized personal security;
(4) solidifying as lumpd in device, being difficult to clean out, easier dust stratification in device, form vicious cycle;
(5) there is shutter in the device had, disclose not open after blocking at all.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of anti-laying dust, dredging dedusting boiler measure anti-blocking sampler.
The purpose of this utility model can be achieved through the following technical solutions:
Anti-blocking sampler measured by a kind of boiler, in order to measure the flue gas pressures of coal-fired power plant unit boiler, pressure reduction and air quantity, comprise main cylinder and the measurement cylindrical shell be communicated with main cylinder respectively and blow grey compressed air piping, described measurement inner barrel is provided with transmitter, this device also comprises dedusting assembly, described dedusting assembly comprises the handle, connecting link and the shovel dirt head that connect successively, and described shovel dirt head is arranged on main cylinder inside, and slides up and down in main cylinder.
Described main cylinder top is provided with gland bonnet, and described connecting link one end is connected with shovel dirt head through gland bonnet, and the other end is connected with handle.
Described shovel dirt head comprises spiral pointed nose and columniform bottom, is provided with multiplely circumferentially equally distributedly to revolve tooth in described bottom, and described pointed nose top is connected with connecting link.
Described connecting link comprises the upper connecting rod and lower connecting rod that are hinged, and the hinged activity point of view of described upper connecting rod and lower connecting rod is 0-90 degree.
Described blowing on grey compressed air piping is also provided with pressure maintaining valve.
Compared with prior art, the utility model has the following advantages:
One, anti-laying dust: the utility model is when measuring, the pressure stabilization function of pressurized air pressure maintaining valve on over-blowing ash compressed air piping is blown in main cylinder, due to the effect of the spirality pointed nose of shovel dirt head, air-flow forms constant voltage environment in main cylinder, and flow to tested end in the shape of a spiral, dust in tested flue gas in main cylinder can not be rested on barrel, and along with helical airflow blowout main cylinder, thus prevent laying dust.
Two, dredge dedusting: when there is laying dust in main cylinder, open gland bonnet, rotate and promoted to main cylinder inside by handle simultaneously, laying dust is wiped off by the tooth that revolves of shovel dirt head bottom, thus completes dedusting work.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As shown in Fig. 1 and Fig. 4 a-4c, anti-blocking sampler measured by a kind of boiler, in order to measure the flue gas pressures of coal-fired power plant unit boiler, pressure reduction and air quantity, the measurement cylindrical shell 2 comprising main cylinder 1 and be communicated with main cylinder 1 and blow grey compressed air piping 3, measure cylindrical shell 2 inside and be provided with transmitter, this device also comprises dedusting assembly, and dedusting assembly comprises the handle 41, connecting link 42 and the shovel dirt head 43 that connect successively, it is inner that shovel dirt head 43 is arranged on main cylinder 1, and slide up and down in main cylinder 1.
Main cylinder 1 top is provided with gland bonnet 11, connecting link 42 one end is connected with shovel dirt head 43 through gland bonnet 11, the other end is connected with handle 41, shovel dirt head 43 comprises spiral pointed nose 431 and columniform bottom 432, be provided with in bottom 432 and multiplely circumferentially equally distributedly revolve tooth 433, pointed nose 431 top is connected with connecting link 42, connecting link 42 comprises the upper connecting rod 421 and lower connecting rod 422 that are hinged, the hinged activity point of view of upper connecting rod 421 and lower connecting rod 422 is 0-90 degree, blows on grey compressed air piping 3 and is also provided with pressure maintaining valve 5.
As shown in Figure 2, the utility model is when measuring, the pressure stabilization function of pressurized air pressure maintaining valve 5 on over-blowing ash compressed air piping 3 is blown in main cylinder 1, due to the effect of the spirality pointed nose of shovel dirt head 43, air-flow forms constant voltage environment in main cylinder 1, and flows to tested end in the shape of a spiral, and the dust in the tested flue gas in main cylinder 1 can not be rested on barrel, and along with helical airflow blowout main cylinder, thus prevent laying dust.
When there is laying dust in main cylinder, open gland bonnet, rotate and promoted to main cylinder inside by handle simultaneously, laying dust is wiped off by the tooth that revolves of shovel dirt head bottom, thus completes dedusting work.
