Abstract
The invention discloses a coal powder sampler. The coal powder sampler comprises a sampling head, an air pump, an exhaust pipe, an ash collecting hopper and a sample storage device and further comprises a solid-gas separator, a first piezometer tube and a second piezometer tube, wherein the sampling head is connected with an inlet of the solid-gas separator through a pipeline, a valve is arranged on a sweeping pipe, a first end of the first piezometer tube is positioned in the pipeline between the sampling head and the solid-gas separator, a second end of the first piezometer tube is connected with one end of a U-shaped pipe, a first end of the second piezometer tube is positioned in the coal pipe, a second end of the second piezometer tube is connected with the other end of the U-shaped pipe, and the U-shaped pipe is filled with a liquid. Through the regulation of the valve, the liquid in the two pipes of the U-shaped pipe is at the same height under the action of pressure in the first piezometer tube and pressure in the second piezometer tube, so that pressure in the pipeline and the coal pipe is balanced, and sampling trueness is improved.
Description
Technical field
The present invention relates to a kind of dust collector, particularly relate to a kind of coal powder sampler.
Background technology
The main harm of coal dust is it is respirable dust, if people suck too much, tuberculosis will be suffered from, and coal dust becomes airborne dust, then pollute the environment, therefore monitor and monitor extremely important to the coal dust discharge of contaminated environment, coal powder sampler is the pith that monitoring and supervising device are carried out in coal dust discharge, existing coal powder sampler does not generally arrange the device of air balance, make the authenticity of sampling low, also part coal dust sampler is had to be provided with air flow balancing unit, but its air flow balancing unit complex structure, and then make the cost of coal fines sampling apparatus higher.
Summary of the invention
Object of the present invention is just to provide a kind of coal powder sampler to solve the problem.
In order to achieve the above object, present invention employs following technical scheme:
A kind of coal powder sampler, comprise collection head, aspiration pump, gas outlet, flue-dust retainer and sample memory, described a kind of coal powder sampler also comprises solid-gas separator, first piezometric tube and the second piezometric tube, described collection head is connected with the entrance of solid-gas separator by pipeline, the gas vent of described solid-gas separator is connected with described gas outlet, described gas outlet is connected with the air intake vent of described aspiration pump, the solid outlet of described solid-gas separator is connected with described flue-dust retainer, the bottom of described flue-dust retainer is connected with described sample memory, pipeline between described collection head and described solid-gas separator is connected with cleaning pipe by Y-pipe, described cleaning pipe is provided with valve, in the first end of the described first piezometric tube pipeline between described collection head and described solid-gas separator, second end of described first piezometric tube is connected with one end of described " U " type pipe, the first end of described second piezometric tube is positioned at coal pipe, second end of described second piezometric tube is connected with the other end of described " U " type pipe, described " U " type pipe is built with liquid.
In said structure, valve, the first piezometric tube, the second piezometric tube and " U " type pipe, make the pressure in energy equalizing main of the present invention and in coal pipe, improve the authenticity of sampling.
Particularly, the first end of described first piezometric tube and the first end of described second piezometric tube are equipped with solid particle filter; Described first piezometric tube and described second piezometric tube are all connected with described " U " type pipe by silicone tube; Described liquid is water.
Beneficial effect of the present invention is:
The present invention is by adjustment valve, under making the pressure effect of pressure in the first piezometric tube of liquid in " U " type pipe and the second piezometric tube, the height of liquid in two pipes in " U " type pipe is the same, thus the pressure in balance inventive pipeline and in coal pipe, improve the authenticity of sampling.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of coal powder sampler of the present invention.
In figure: 1-collection head, 2-first piezometric tube, 3-solid-gas separator, 4-aspiration pump, 5-gas outlet, 6-valve, 7-flue-dust retainer, 8-sample memory, 9-" U " type pipe, 10-second piezometric tube, 11-solid particle filter.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of coal powder sampler of the present invention, comprise collection head 1, aspiration pump 4, gas outlet 5, flue-dust retainer 7 and sample memory 8, a kind of coal powder sampler also comprises solid-gas separator 3, first piezometric tube 2 and the second piezometric tube 10, collection head 1 is connected by the entrance of pipeline with solid-gas separator 3, the gas vent of solid-gas separator 3 is connected with gas outlet 5, gas outlet 5 is connected with the air intake vent of aspiration pump 4, the solid outlet of solid-gas separator 3 is connected with flue-dust retainer 7, the bottom of flue-dust retainer 7 is connected with sample memory 8, pipeline between collection head 1 and solid-gas separator 3 is connected with cleaning pipe by Y-pipe, cleaning pipe is provided with valve 6, in the first end of the first piezometric tube 2 pipeline between collection head 1 and solid-gas separator 3, second end of the first piezometric tube 2 is connected with one end of " U " type pipe 9, the first end of the second piezometric tube 10 is positioned at coal pipe, second end of the second piezometric tube 10 is connected with the other end of " U " type pipe 9, the first end of the first piezometric tube 2 and the first end of the second piezometric tube 10 are equipped with solid particle filter 11, first piezometric tube 2 and the second piezometric tube 10 are all connected with " U " type pipe 9 by silicone tube, and " U " type pipe 9 is built with liquid, liquid is water.
The principle of the invention is as follows:
Breeze airflow is after collection head 1, solid-gas separator 3 is entered through piping, coal dust is because of gravity inertial effect whereabouts, sample memory 8 is entered through flue-dust retainer 7, and gas is discharged by gas outlet 5 under the suction of aspiration pump 4, adjustment valve 6, under making the pressure effect of pressure in the first piezometric tube 1 of liquid in " U " type pipe 9 and the second piezometric tube 10, the height of liquid in two pipes in " U " type pipe 9 is the same, then can start sampling, such pressure that can balance in inventive pipeline and in coal pipe, increase the authenticity of sampling, the present invention is by passing into pressurized air from valve 6, cleaning the present invention.
