Abstract
The utility model relates to verify accessories of dust monitors and particularly relates to a quantitative dust feeding device which comprises a rack; a funnel type powder material bin is arranged on the rack; a pipe type spiral conveyer is assembled at a discharging port of the powder material bin; the pipe type spiral conveyer comprises a shell and a screw rod which is assembled in the shell; one end of the screw rod is used for being in transmission connection with a powder input end of a driving device; a powder spraying port and an air inlet which is used for being connected with a fan are formed in one end (on the screw rod) of the shell of the pipe type spiral conveyer; during the use processing, powder materials can be received and output in a quantitative manner from the powder bin by the pipe type spiral conveyer; the powder materials which are output by the pipe type spiral conveyer form dust under the action of the fan, and the dust can be stably sent to the corresponding dust monitor so as to be verified; and during the verifying process, only the rotation speed of the screw rod and the stability of the wind power of the fan are ensured, so that the dust can be fed in the quantitative and uniform way, and the reliability of the verifying result of the dust monitor can be improved.
Description
Technical field
The utility model relates to the verification annex of dust measurement, and is especially a kind of quantitatively to the dirt device.
Background technology
Dust more and more is taken seriously the harm of health, and is therefore at present also more and more deep to the research of the technology of dust measurement.Wherein Mine Dust is at present the mankind to be endangered one of maximum, the highest dangerous dust, and Mine Dust refers to the general name of the fine solid particles such as coal that the colliery produces in process of production, rock.Each production link under the colliery all may produce dust, such as jewel hole link, explosive blasting link, development machine driving link, coalcutter coal cutting link, the link of coalingging, coal mining supporting caving link, roadway support link, loading and unloading transit link etc., different from common ground dust is, Mine Dust can not only make the workman suffer from pneumoconiosis, and very likely explosion caused, cause serious accident.
At present the control of dust still is in the monitoring stage, namely by monitoring and follow-up processing method dust concentration is remained on a scope that safety is suitable, especially for the monitoring of Mine Dust, a large amount of research has all been made in countries in the world, a series of dust monitoring instruments have been developed, such as dust sampler, dust gauge, sensor of dust concentration, or even dust concentration is calculated machine testing system etc.
The appearance of dust monitoring instrument has brought a thread dawn for undoubtedly the control of dust accident, but, fully take the testing result of dust monitoring instrument under the prerequisite of reference, the precision of dust monitoring instrument has just become vital factor in the dust Accident prevention process, verification to dust monitoring instrument then seems very important, and in the checking procedure to dust monitoring instrument, give the reliability of the accuracy affects device check results of dust quantity.
Summary of the invention
The purpose of this utility model be to provide a kind of can accurately control to dust quantity quantitatively to the dirt device, to improve the reliability to the check results of dust monitoring instrument.
In order to address the above problem, of the present utility model quantitatively to the dirt device by the following technical solutions: a kind of quantitatively to the dirt device, comprise frame, frame is provided with flared filler bin, the drain hole place of filler bin is equipped with tube-type spiral conveyer, described tube-type spiral conveyer comprises housing and is assemblied in screw rod in the housing, the power intake of one end of screw rod for being used for being in transmission connection with actuating device is provided with the mouth that dusts at the end place away from its power intake of screw rod on the housing of tube-type spiral conveyer and reaches for the ventilation inlet that is connected with blower fan.
Described screw rod is connected with actuating device by its power intake, and described actuating device is motor.
Described motor is stepless speed-change motor.
The housing of tube-type spiral conveyer is connected with blower fan by described ventilation inlet.
Be provided with in the described filler bin be used to preventing that dust from stopping up the mixing device of the drain hole of filler bin.
Be provided with airer in the described filler bin.
Quantitatively adopt flared filler bin and be equipped with tube-type spiral conveyer at the drain hole place of filler bin to the dirt device owing to of the present utility model, and be provided with the ventilation inlet that dusts mouthful and be used for being connected with blower fan on the housing of tube-type spiral conveyer at the end place away from its power intake of screw rod, therefore, in the process of using, the screw rod of tube-type spiral conveyer can be connected with actuating device, with the ventilation inlet of housing and corresponding blower fan connection, thereby realize from the drain hole of filler bin quantitative reception and output powder by described tube-type spiral conveyer, the powder of being exported by tube-type spiral conveyer forms the dust pulsation-free and is delivered to corresponding dust monitoring instrument so that it is carried out verification under the effect of blower fan, what only need guarantee the rotating speed of screw rod and blower fan wind-force in checking procedure steadily can realize quantitative and even to dirt, thereby improves the reliability to the check results of dust monitoring instrument.
Further, actuating device adopts motor can realize easily the uniform rotation of screw rod, motor is made as stepless speed-change motor can realizes the convenient of Dust Capacity of output regulated, and realizes the multiple spot verification to dust monitoring instrument; Mixing device can prevent that the powder caking from stopping up the drain hole of filler bin, and airer has then further been avoided the appearance of the problem of the moist caking of powder.
