Abstract
The invention discloses an automatic membrane changing device of a multi-filter-membrane ambient air particle sampler. The automatic membrane changing device comprises a filter membrane dustproof box, a rotary plate for bearing filter membranes, a rotary plate driving device, and a filter membrane locating sensor, wherein a plurality of holes for mounting the filter membranes are uniformly formed in the rotary plate for bearing the filter membranes; the rotary plate is driven by an electric motor and a transmission device so as to realize automatic membrane changing; the filter membrane locating sensor is connected with a controller for guaranteeing accurate locating of the filter membranes and a sampling hole and determining the sequence of the filter membranes. The device has the advantages that the sampler can work for a few days continuously, and the limitation that a single filter membrane sampler commonly used at present can only work one day continuously and a filter membrane needs to be changed at a fixed time every day is overcome; the continuity, reliability and applicability of ambient air particle monitoring are improved; the cost of manual maintenance is saved; the operating cost is reduced. Moreover, the influence of man power to monitoring results is alleviated, and measurement errors are reduced. The multi-filter-membrane ambient air particle sampler is an upgrading product of a traditional ambient air particle sampler.
Description
Technical field
The present invention relates to surveying instrument technical field, 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.
Summary of the invention
For addressing the above problem, the object of this invention is 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 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 a plurality of 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 filter membrane and thief hatch accurately location and definite filter membrane order.
Described many filter membranes are that the quantity of carrying filter membrane on rotating disk is more than 2 by the disk carrying of a horizontal positioned.
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.
Advantage of the present invention is: many filter membranes Automatic change film device of the present invention, can effectively extend sampling thief continuous working number of days, and guaranteed the continuity of sampling; Can make sampling thief work (number of days=filter membrane number of maximum functional) in continuous many days.5 filter membranes of take are 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 invention can effectively solve above-mentioned drawback.
