Description
Technical field
The utility model relates to surveying instrument technical field, and specifically a kind of air granule sampler is more specifically a kind of Automatic change film device.
Background technology
At present, conventional ambient air particulate matter sampling thief is all single filter membrane sampler, the mode of operation of this sampling thief is to sample every day after 20-23 hour, must in remaining 4-1 hour, old filter membrane be taken out and more renew filter membrane, then starts sampling thief and works on.If when running into the special circumstances such as inclement weather, traffic congestion, human factor and cannot complete filter membrane replacing at short notice, will affect the continuity of air quality monitoring, cause monitoring to interrupt and shortage of data.
Utility model content
For addressing the above problem, the purpose of this utility model be to provide a kind of many filter membranes ambient air particulate matter sampling thief use many filter membranes and can automatically change the device of filter membrane, concrete technical scheme is as follows:
An Automatic change film device for many filter membranes ambient air particulate matter sampling thief, comprises filter membrane dirt seal housing, also comprises rotating disk, rotating blade drive, filter membrane alignment sensor of carrying by filter membrane etc.; Uniform multiple holes that are used for installing filter membrane on the rotating disk of carrying filter membrane, thus described rotating disk is realized Automatic change film by motor and actuator drives, and described sensor is connected with controller, is used for guaranteeing accurately location and definite filter membrane order of filter membrane and thief hatch.
Described many filter membranes are to be carried by the disk of a horizontal positioned, and the quantity of carrying filter membrane on rotating disk is more than 2.
Described Automatic change film rotating disk is arranged in a dirt seal housing, prevents that the sample on the filter membrane after sampling finishes is blown away, and also prevents that new filter membrane is by contamination by dust simultaneously.
Described gearing comprises base plate, sliding cross coupling, supporting seat, bearing, axle, bearing cap, adapter sleeve etc., motor is fixed on base plate, motor shaft is connected with axle by sliding cross coupling, axle is fixed by the bearing being fixed on supporting seat, axle and adapter sleeve are fixed, and adapter sleeve and rotating disk are fixed; Bearing arranged outside bearing holder (housing, cover).Described alignment sensor comprises sequential sensor and position transducer, and described controller is connected with sensor, is used for sending the work orders such as Automatic change film, have simultaneously detection, regularly, the Circuits System of the function such as control, demonstration.
The utility model has the advantages that: many filter membranes Automatic change film device of the present utility model, can effectively extend sampling thief continuous working number of days, guaranteed the continuity of sampling; Can make sampling thief work (number of days=filter membrane number of maximum functional) in continuous many days.Take 5 filter membranes as example, the longest continuous working number of days is 5 days 120 hours, and the random time in these 120 hours is changed filter membrane can, effectively overcome the only continuous working one day of single filter membrane sampler, the drawback that must regularly change filter membrane every day, has improved reliability and applicability, has saved manpower maintenance cost, having reduced operating cost, is the renewal product of traditional environment air particle hand sampling device.In addition, because filter membrane system need be monitored air particles in sealed environment, in case the accuracy of environmental impact measurement result, and change by hand frequently filter membrane, certainly will cause the error of measurement result to increase; Automatic change film device of the present utility model can effectively solve above-mentioned drawback.
