The utility model discloses the dustless sampler of a kind of direct-blowing type coal mill tube cell, comprise the mount pad (7) be arranged on coal pulverizer flour extraction pipe, it is characterized in that: described mount pad (7) is provided with the air inlet base (5) arranged perpendicular to flour extraction pipe, the other end opening part of air inlet base (5) adopts the plug (3) perpendicular to flour extraction pipe to close, be provided with the draft tube (2) perpendicular to air inlet base (5) at the sidepiece of air inlet base (5), draft tube (2) is provided with ball valve (1).The utility model by optional position being installed the dustless sampler of this cover on direct-blowing type coal mill flour extraction pipe, and air pressure during sampling in air inlet base is that barotropic state makes the coal dust in flour extraction pipe can not flow in air via the ejection of air inlet base relative to the air pressure in flour extraction pipe, guarantees that surrounding environment is not contaminated from face; Above-mentioned sampler structure is simple, easy to use and can available protecting environment, therefore suitablely promotes the use of.
Description
Technical field
The utility model relates to the dustless sampler of a kind of direct-blowing type coal mill tube cell in power industry application.
Background technology
Current power industry direct-blowing type coal mill tube cell sampling method used is directly on pulverized coal channel, open sample tap substantially, sample tap is opened during sampling, by sampling gun by sampling in sample tap Inserting Tube, because pipe interior is positive pressure system in sampling process, coal dust in pipeline can pass through sample tap ejection passage, pollutes surrounding environment.
Summary of the invention
The purpose of this utility model is for prior art Problems existing, provides a kind of and can be arranged on optional position on direct-blowing type coal mill flour extraction pipe and can carry out the dustless sampler of direct-blowing type coal mill tube cell of online dustless sampling at any time.
The purpose of this utility model solves by the following technical programs:
The dustless sampler of a kind of direct-blowing type coal mill tube cell, comprise the mount pad be arranged on coal pulverizer flour extraction pipe, it is characterized in that: described mount pad is provided with the air inlet base arranged perpendicular to flour extraction pipe, the other end opening part of air inlet base adopts the plug perpendicular to flour extraction pipe to close, be provided with the draft tube perpendicular to air inlet base at the sidepiece of air inlet base, draft tube is provided with ball valve.
The coal dust that described draft tube is used for when input compressed-air makes plug open in flour extraction pipe can not spray from air inlet base.
Described draft tube is arranged perpendicular to air inlet base.
Described plug to be connected with air inlet base by screw thread and to be provided with plug O-ring seal between plug and air inlet base.
Described mount pad and air inlet base junction are provided with the base seal for sealing.
The utility model has the following advantages compared to existing technology:
The utility model by optional position being installed the dustless sampler of this cover on direct-blowing type coal mill flour extraction pipe, when this point needs sampling, pressurized air can be accessed draft tube, open ball valve valve pressurized air to be entered in air inlet base make the air pressure in air inlet base be barotropic state relative to the air pressure in flour extraction pipe, then plug is turned on, sampling gun is inserted in flour extraction pipe through air inlet base and samples, because the air pressure in air inlet base is that barotropic state makes coal dust in flour extraction pipe can not flow in air via the ejection of air inlet base relative to the air pressure in flour extraction pipe, guarantee that from face surrounding environment is not contaminated, above-mentioned sampler structure is simple, easy to use and can available protecting environment, can be arranged on optional position on each flour extraction pipe of coal pulverizer simultaneously, and only need scene to provide pressurized air, be suitable for promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-ball valve; 2-draft tube; 3-plug; 4-plug O-ring seal; 5-air inlet base; 6-base seal; 7-mount pad.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: the dustless sampler of a kind of direct-blowing type coal mill tube cell, comprise the mount pad 7 be arranged on coal pulverizer flour extraction pipe, described mount pad 7 is provided with the air inlet base 5 arranged perpendicular to flour extraction pipe, mount pad 7 and air inlet base 5 junction are provided with the base seal 6 for sealing; The plug 3 perpendicular to flour extraction pipe is adopted to close at the other end opening part of air inlet base 5, plug 3 to be connected with air inlet base 5 by screw thread and to be provided with plug O-ring seal 4 between plug 3 and air inlet base 5, be provided with the draft tube 2 perpendicular to air inlet base 5 at the sidepiece of air inlet base 5, draft tube 2 is provided with ball valve 1; Coal dust when this draft tube 2 makes plug 3 open for input compressed-air in flour extraction pipe can not spray from air inlet base 5.In above-mentioned sampler, generally draft tube 2 is arranged perpendicular to air inlet base 5 or draft tube 2 is arranged to improve compressed-air actuated closure towards mount pad 7.
When dustless sampler of the present utility model uses, first by the pressurized air at scene access draft tube 2, the valve opening ball valve 1 makes pressurized air enter in air inlet base 5 to make the air pressure in air inlet base 5 be barotropic state relative to the air pressure in flour extraction pipe, then turn on plug 3, sampling gun is inserted in flour extraction pipe through air inlet base 5 and samples; After sampling completes, extract sampling gun, tighten plug 3, close ball valve 1, finally remove pressurized air, namely complete once dustless sampling.
The utility model by optional position being installed the dustless sampler of this cover on direct-blowing type coal mill flour extraction pipe, when this point needs sampling, pressurized air can be accessed draft tube 2, the valve opening ball valve 1 makes pressurized air enter in air inlet base 5 to make the air pressure in air inlet base 5 be barotropic state relative to the air pressure in flour extraction pipe, then plug 3 is turned on, sampling gun is inserted in flour extraction pipe through air inlet base 5 and samples, because the air pressure in air inlet base 5 is that barotropic state makes coal dust in flour extraction pipe can not spray via air inlet base 5 to flow in air relative to the air pressure in flour extraction pipe, guarantee that from face surrounding environment is not contaminated, above-mentioned sampler structure is simple, easy to use and can available protecting environment, can be arranged on optional position on each flour extraction pipe of coal pulverizer simultaneously, and only need scene to provide pressurized air can carry out dustless sampling at any time, suitablely promotes the use of.
Above embodiment is only and technological thought of the present utility model is described, protection domain of the present utility model can not be limited with this, every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain; The technology that the utility model does not relate to all is realized by prior art.
