Abstract
The utility model discloses a dry slag sampling device for a power station boiler with a dry-type slag removal system. The dry slag sampling device comprises a long-handle spoon A and a long-handle spoon B which are connected with each other by virtue of a hinge, wherein the top ends of the long-handle spoon A and the long-handle spoon B are respectively a hemi-spherical spoon body A and a hemi-spherical spoon body B matched with each other; suck-back prevention teeth are uniformly arranged in the spoon body A and the spoon body B; a tension spring is arranged between a spoon handle of the long-handle spoon A and a spoon handle of the long-handle spoon B. The power station boiler dry slag sampling device disclosed by the utility model can be used for effectively preventing large slag samples from being absorbed, is short in sampling time, has representativeness, can meet the laboratory test needs by virtue of one-time sampling, is convenient to use, and is specially used for sampling of the power station boiler with the dry-type slag removal system.
Description
Technical field
The utility model relates to a kind of for the dry slag sampling apparatus on the station boiler with dry bottom ash handling system.
Technical background
In order to reach energy-conservation effect, increasing station boiler adopts dry bottom ash handling system.Dry bottom ash handling system adopts air cooling, and total system adopts negative-pressure design.When carrying out the large slag specimen of station boiler test collection, often need to open the manhole door sampling at slag drying machine top, generally with common spoon with long handle sampling, but because system is with negative pressure, leaking out from manhole door to slag drying machine often siphons away the large slag specimen in strockle, make the large slag specimen of collection not representative, and for reaching enough sample size samplings repeatedly for a long time, to testing crew, bring unsafe factor.
Utility model content
Problem to be solved in the utility model is to provide a kind of power station boiler dry slag sampling apparatus that can effectively prevent that large slag specimen is sucked away.
The technical solution adopted in the utility model:
A kind of power station boiler dry slag sampling apparatus, it is characterized in that: comprise the dipper first and the dipper second that are connected through the hinge, the top of the top of described dipper first and dipper second is respectively hemispheric spoon body first and the spoon body second cooperatively interacting, in described spoon body first and spoon body second, be evenly provided with anti-suck tooth, between the kettleholder of dipper first and the kettleholder of dipper second, be provided with extension spring.
Preferably, the internal diameter of described spoon body first equates with the external diameter of spoon body second.
Further, described kettleholder end is provided with sleeve.
The beneficial effects of the utility model:
When using the large slag specimen of the utility model collection, to both sides, pull open respectively dipper first and dipper second, now extension spring is in extended state, hemispherical spoon body first and hemispherical spoon body second are sent in slag drying machine and sampled, large slag specimen is stopped by the anti-suck tooth in spoon body after entering spoonful body, can prevent that most of slag specimen from being siphoned away by negative pressure wind; After sampling, unclamp at once kettleholder, under the effect of extension spring, spoon body first and spoon body second are closed, can effectively prevent that large slag specimen is sucked away; The internal diameter of spoon body first equates with an external diameter for spoon body second, and spoon body closure rear section coincidence can further guarantee the leakproofness of spoonful intracorporeal space the slag specimen of obtaining to be all retained in spoonful body.Kettleholder end is provided with sleeve, when sampling area, crosses the length of this device far away when inadequate, and available wooden handle is sleeved in sleeve to increase length.
The utility model can effectively prevent that large slag specimen is sucked away, and sample time is short, and representative, and once sampling can meet chemical examination needs, easy to use, is exclusively used in the station boiler sampling with dry bottom ash handling system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In Fig. 1: 1 is dipper first, 1-1 is spoon body first, and 2 is hinge, and 3 is dipper second, and 3-1 is spoon body second, and 4 is anti-suck tooth, and 5 is extension spring, and 6 is sleeve.
Embodiment
As shown in Figure 1, the utility model comprises dipper first 1 and the dipper second 3 connecting by hinge 2, the top of the top of described dipper first 1 and dipper second 3 is respectively hemispheric spoon body first 1-1 and the spoon body second 3-1 cooperatively interacting, in described spoon body first 1-1 and spoon body second 3-1, be evenly provided with anti-suck tooth 4, between the kettleholder of dipper first 1 and the kettleholder of dipper second 3, be provided with extension spring 5.When using the large slag specimen of the utility model collection, to both sides, pull open respectively dipper first 1 and dipper second 3, now extension spring 5 is in extended state, hemispherical spoon body first 1-1 is sent in slag drying machine and sampled with a spoon body second 3-1, large slag specimen is stopped by the anti-suck tooth 4 in spoon body after entering spoonful body, can prevent that most of slag specimen from being siphoned away by negative pressure wind; After sampling, unclamp at once kettleholder, under the effect of extension spring 5, spoon body first 1-1 and spoon body second 3-1 are closed, can effectively prevent that large slag specimen is sucked away.
Preferably, the internal diameter of described spoon body first 1-1 equates with an external diameter of spoon body second 3-1, and during sampling, spoon body 3-1 is positioned at below, and two spoon body closure rear sections coincidences can further guarantee the leakproofness of spoonful intracorporeal space the slag specimen of obtaining to be all retained in spoonful body.In order to guarantee closure effect, the edge of spoon body first does not arrange anti-suck tooth.
Further, described kettleholder end is provided with sleeve 6, when sampling area, crosses the length of this device far away when inadequate, and available wooden handle is sleeved in sleeve to increase length.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of making within spirit of the present utility model and principle, be equal to and replace and improvement etc., within being all included in protection domain of the present utility model.
