Abstract
The utility model relates to an automatic paper feeding device for measuring a radioactive aerosol. The automatic paper feeding device comprises a controller, a differential pressure gauge, a flow meter, a filter box, an air inlet nozzle and an exhaust pipe, wherein the air inlet nozzle and a driving mechanism are arranged in the filter box; and the driving mechanism consists of a paper feeding wheel, an alarm wheel, a counting wheel, a paper collecting wheel and a motor. The automatic paper feeding device is characterized in that: a paper belt passes through the paper feeding wheel, the alarm wheel, a clearance between the lower end of the air inlet nozzle and the upper end of the exhaust pipe, the counting wheel and the paper collecting wheel; an input end of the differential pressure gauge is respectively connected with the air inlet nozzle and the exhaust pipe; the flow meter is connected in series to the exhaust pipe; output ends of the differential pressure gauge, the flow meter and the counting wheel are respectively connected with pressure difference, flow and counting signal input ends of the controller; and the output end of the controller is connected with the input end of the motor. The automatic paper feeding device is simple in structure, reliable and stable in paper feeding, accurate in failure discrimination, and convenient to use.
Description
Technical field
The utility model relates to chart drive assembly, is that the automatic carriage device is used in a kind of radioaerosol measurement specifically.
Background technology
Radioaerosol is measured and to be widely used in radioaerosol monitoring equipment in nuclear safety and the radiation protection with chart drive assembly, and existing chart drive assembly not only often breaks down, can not steady operation, and filter paper to change operation loaded down with trivial details, daily use is inconvenient; Especially often walk to cause radiomaterial to deposit because of few, perhaps because of walking to cause expensive extraordinary filter paper waste more.Therefore design a kind of simple in structure, paper feed reliable and stable, fault is screened radioaerosol accurate, easy to use and is measured with the automatic carriage device very necessary.
Summary of the invention
The purpose of the utility model just provides a kind of simple in structure, paper feed reliable and stable, fault and screens radioaerosol accurate, easy to use and measure and use the automatic carriage device.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of radioaerosol is measured and is used the automatic carriage device; Comprise controller, differential manometer, flowmeter, filter box, admission piece and gas outlet; Admission piece and by the driving mechanism that feed roller, warning wheel, counter wheel, paper collecting roller and motor are formed be arranged at the filter box in; It is characterized in that paper tape from the gap of feed roller between on the wheel of reporting to the police, admission piece lower end and the gas outlet, counter wheel to paper collecting roller, the input end of differential manometer is connected with gas outlet with admission piece respectively, the output terminal of differential manometer is connected with the pressure difference signal input end of controller; Flowmeter is serially connected on the gas outlet; The output terminal of flowmeter is connected with the flow signal input end of controller, and the output terminal of counter wheel is connected with the count signal input end of controller, and the output terminal of controller is connected with the input end of motor.
Further, said gas outlet connects through flexible pipe between the inside and outside two parts of filter box.
The utility model is owing to the employing control system, thereby the accurate control of the reliable and stable and paper feed distance of assurance paper feed process has effectively been avoided walking to cause the radiomaterial deposition perhaps to waste because of the extraordinary filter paper of walking to cause costliness because of few more.It is accurate, easy to use that the utility model is simple in structure, paper feed reliable and stable, fault are screened.
