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 after sampling every day 20-23 hour, must be taken out by old filter membrane in remaining 4-1 hour and more renew filter membrane, then start sampling thief and work on.If run into the special circumstances such as inclement weather, traffic congestion, human factor when cannot complete filter membrane replacing at short notice, the continuity of air quality monitoring will be affected, cause monitoring to interrupt and shortage of data.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of many filter membranes of use of many filter membranes ambient air particulate matter sampling thief and automatically can 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, the filter membrane alignment sensor of carrying filter membrane; On the rotating disk of carrying filter membrane, uniform multiple being used for installs the hole of filter membrane, and described rotating disk is by motor and actuator drives thus realize Automatic change film, and described sensor is connected with controller, is used for guarantee filter membrane and thief hatch accurately locate and determine that filter membrane sequentially.
Described gearing comprises base plate, sliding cross coupling, supporting seat, bearing, axle, bearing cap, adapter sleeve, motor is fixed on base plate, motor shaft is connected with axle by sliding cross coupling, axle is fixed by the bearing be 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 rotating disk also arranges the multiple accurate pilot hole identical with filter membrane mounting hole quantity, and the corresponding alignment sensor of described accurate pilot hole, described alignment sensor is connected with controller.
Described many filter membranes are carried by the disk of a horizontal positioned, and quantity rotating disk carrying filter membrane is more than 2.
Described Automatic change film rotating disk is arranged in described filter membrane dirt seal housing, and the sample on the filter membrane after terminating that prevents from sampling is blown away, and also prevents new filter membrane by contamination by dust simultaneously.
Described alignment sensor comprises sequential sensor and position transducer, described controller is connected with sensor, be used for sending Automatic change film work order, have simultaneously detection, regularly, control, the Circuits System of Presentation Function, concrete structure is: arrange sequential sensor with filter membrane mounting hole correspondence position below described rotating disk, described sequential sensor is connected with controller; The quantity that described sequential sensor collection filter membrane mounting hole turns over also passes to controller, controlled the anglec of rotation of rotating disk according to the quantity that filter membrane mounting hole turns over by controller, whether alignment sensor gathers the signal of motor rotation/stopping and passing to controller, and then rotated by controller control motor.
Advantage of the present invention is: many filter membranes Automatic change film device of the present invention, effectively can extend sampling thief continuous working number of days, ensure that the continuity of sampling; Sampling thief work (number of days=filter membrane number of maximum functional) in continuous many days can be made.For 5 filter membranes, the longest continuous working number of days is 5 days 120 hours, and the random time in these 120 hours changes filter membrane can, effectively overcome the only continuous working one day of single filter membrane sampler, regularly must change the drawback of filter membrane every day, improve reliability and applicability, save manpower maintenance cost, reducing operating cost, is the renewal product of traditional environment air particle hand sampling device.In addition, because filter membrane system need monitor air particles in sealed environment, in order to avoid the accuracy of environmental impact measurement result, and change filter membrane by hand frequently, the error of measurement result certainly will be caused to increase; Automatic change film device of the present invention can effectively solve above-mentioned drawback.
