Abstract
The utility model discloses a kind of dedusting ash silometer, comprise communicating pipe, the lower end of described communicating pipe is connected on the outer wall of fly-ash separator ash silo, and fly-ash separator ash silo and communicating pipe junction outer wall on have perforate, by perforate, fly-ash separator ash silo was communicated with communicating pipe, also be provided with pressure unit in the upper end of described communicating pipe, described pressure unit is connected to middle control picture by PLC.Dedusting ash silometer device of the present utility model accurately can locate fly-ash separator ash silo material level, judge whether that needs put ash, stop because the unloading valve after storehouse and dust emptying that rises of the too high initiation of dust material level in fly-ash separator leaks out and causes fly-ash separator reentrainment of dust phenomenon to occur, and apparatus structure is simple, with low cost, be convenient to promote.
Description
Technical field
The utility model relates to field of environment protection equipment, particularly a kind of dedusting ash silometer.
Background technology
The ash silo of fly-ash separator is parts very important in dust collection device, dust collection in dust removal process gets up by it, with the fiber bag precipitator the most widely of application, when the flue gas containing a large amount of dust of air intake opening collides on the cloth bag of blocks dust under powerful negative pressure, the part that quality is larger directly falls into ash silo, the dust that quality is little is attached to cloth bag surface, under the outer effect of back-blowing or pulse valve air-flow, mechanical shaking is to reach the process of deashing, the dust of cleaning all falls into ash silo, the fly-ash separator be in for a long time in operating mode is all generally continuous working, online sub-room cleaning, at this moment a large amount of cleaned dusts falls into ash silo continuously, the volume of ash silo is but limited, so must one will be had to feed back signal to PLC system before filling by dust in ash silo, the dust in ash silo is cleaned out to work on to arrange the time, at this moment general ash silo part can be equipped with that the defeated grey equipment such as spiral ash machine or scrapper conveyor is convenient is shifted out dust.Feedback signal in above process just needs the instrument of the position of detection dust in ash silo be arranged in ash silo, and in ash silo, ash has how many, so that organization work to have had it just can know.
The ash silo level detector having the workplace of dust to use at present adopts electronic switch level-sensing device, often because internal environment is severe and level-sensing device probe bridging and electric fault affect, make level-sensing device cisco unity malfunction, thus cause powder ash silo material level to be forbidden, affect the normal operation that fly-ash separator puts ash and equipment.In addition existing dedusting level-sensing device only can in middle control display, and the position of ash silo ash cannot be known in scene, for daily Operation and Maintenance brings inconvenience.Therefore, study a kind of Novel ash silometer showing ash silo dust position reliably, intuitively and just seem particularly important.
Utility model content
The purpose of this utility model is for solving the problem, and provides a kind of dedusting ash silometer.
In order to achieve the above object, the utility model provides following technical scheme: a kind of dedusting ash silometer, comprise communicating pipe, the lower end of described communicating pipe is connected on the outer wall of fly-ash separator ash silo, and fly-ash separator ash silo and communicating pipe junction outer wall on have perforate, fly-ash separator ash silo be communicated with communicating pipe by perforate, be also provided with pressure unit in the upper end of described communicating pipe, described pressure unit is connected to middle control picture by PLC.
Improve as one of the present utility model, described communicating pipe is also provided with tensimeter.
Improve as one of the present utility model, described tensimeter is directly installed on above or by negative tube guides to the communicating pipe outer place down to operator's handled easily by communicating pipe suction function described communicating pipe, and at negative tube lower end setting pressure table.
Beneficial effect:
Dedusting ash silometer device of the present utility model accurately can locate fly-ash separator ash silo material level, judge whether that needs put ash, stop because the unloading valve after storehouse and dust emptying that rises of the too high initiation of dust material level in fly-ash separator leaks out and causes fly-ash separator reentrainment of dust phenomenon to occur, and apparatus structure is simple, with low cost, be convenient to promote.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation that the utility model is connected with ash silo;
Accompanying drawing 2 is communicating pipe of the present utility model schematic diagram;
Accompanying drawing 3 is PLC control principle drawings;
In figure, each parts are:
1. tensimeter 2. pressure unit
3. communicating pipe 4. access hole
5. discharge duct.
Embodiment
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
A kind of dedusting ash silometer as shown in Figure 1, comprise communicating pipe 3, the lower end of described communicating pipe 3 is connected on the outer wall of fly-ash separator ash silo, and fly-ash separator ash silo and communicating pipe 3 junction outer wall on have perforate, by perforate, fly-ash separator ash silo was communicated with communicating pipe 3, communicating pipe 3 be welded on bottom perforate extreme lower position on.Also be provided with pressure unit 2 in the upper end of described communicating pipe 3, described pressure unit 2 is connected to middle control picture by PLC.Middle control machine picture program arranges corresponding warning.
Further, described communicating pipe 3 is also provided with tensimeter 1, described tensimeter 1 is directly installed on described communicating pipe 3 or by negative tube and communicating pipe suction function is guided to the communicating pipe outer place down to operator's handled easily, and at negative tube lower end setting pressure table.Operating personnel judge the situation of ash silo material level according to this manometric numerical value, so that the arrangement of follow-up work.
Operationally, communicating pipe 3, bottom was from institute's material controlling position by the introducing of perforate on this place's wallboard of fly-ash separator fly-ash separator ash silo, and when dedusting ash material level is higher than pipeline opening, communicating pipe 3 bottom is closed by dedusting ash, does not have negative pressure to produce, and pressure is just for the utility model; If when dedusting ash material level is lower than pipeline opening, in operating fly-ash separator, suction function is in communicating pipe 3, has negative pressure to produce, and pressure is negative, illustrates that dedusting ash material level does not reach institute's material controlling position.If fly-ash separator is shut down, pressure is 0, also illustrates that dedusting ash material level does not reach institute's material controlling position.Bottom residue dedusting ash serves the sealing function to fly-ash separator discharger, avoids the fly-ash separator caused due to dedusting ash emptying to leak out.The utility model is arranged on the minimum control material level of fly-ash separator ash silo, accurately can judge dedusting ash controlling level in fly-ash separator ash silo, determining that operating personnel are the need of putting ash, stopping because causing fly-ash separator air leakage phenomena after dedusting ash material level too high initiation electric field short circuit in fly-ash separator and material emptying.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment; also comprise the technical scheme be made up of above technical characteristic combination in any; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
