Abstract
The utility model relates to a continuous monitor for gaseous effluent of nuclear facilities, particularly a radioactive aerosol continuous paper-feeding detecting apparatus. The utility model comprises an upper fixed seat and a lower fixed seat, wherein the upper fixed seat is provided with a granularity separating and sampling apparatus and two semiconductor alpha detectors, and the lower fixed seat is provided with a beta detector. The lower part of the lower fixed seat is provided with a paper feeding wheel and a paper contracting wheel. A filter paper tape is wound on the paper feeding wheel and is sent to the paper contracting wheel round the lower fixed seat. The paper contracting wheel is driven by a servo motor. The lower fixed seat is provided with a delaying paper guiding wheel. The filter paper tape is round the delaying paper guiding wheel in middle course and is sent to the paper contracting wheel. The device improves the defect of the existing paper feeding and detecting devices and has simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of nuclear facilities gaseous effluent continuous monitoring device, is specially the continuous paper feed sniffer of radioaerosol.
Background technology
The continuous paper feed sniffer of radioaerosol is to use on radioaerosol continuous monitoring equipment, and existing apparatus exists following major defect and deficiency: 1. the volume of holder up and down of equipment is big, and weight is big, and the Installation and Debugging difficulty is big; 2. filter paper transmission and lead the paper gear and be provided with moving tooth, filter paper need punch during use; 3. load and unload the filter paper complicated operation; 4. the gear of paper feed needs is many, and cumulative errors are big, causes the filter paper fracture easily; 5. probe body communicates with chart drive assembly, disturbs counting big.
Summary of the invention
The purpose of this utility model is to provide a kind of equipment simple at the weak point of the existing continuous paper feed sniffer of radioaerosol, uses the continuous paper feed sniffer of more convenient radioaerosol.
The technical scheme of this utility model is as follows: the continuous paper feed sniffer of radioaerosol comprises upper fixed seat and lower fixed seat, upper fixed seat is provided with granularity separating and sampling unit and two semiconductor alpha detection devices, lower fixed seat is provided with beta rediation detector, the lower fixed seat bottom is provided with paper feeding roller and paper collecting roller, the filter paper band is wrapped on the paper feeding roller, and walk around lower fixed seat and deliver to paper collecting roller, paper collecting roller is driven by servomotor, be provided with the time-delay paper guiding roll on lower fixed seat, the filter paper band is walked around the time-delay paper guiding roll halfway and is delivered to paper collecting roller again.
The continuous paper feed sniffer of aforesaid radioaerosol, wherein, lower fixed seat is provided with the length that is used to measure the filter paper transmission and the range finding wheel of distance.
The continuous paper feed sniffer of aforesaid radioaerosol wherein, is respectively equipped with the insulation bucket outside two semiconductor alpha detections of upper fixed seat device.
The utlity model has following advantage: 1. the size with original last lower fixed seat reduces, and has reduced volume and weight, has increased the mobility of instrument; 2. removed original filter paper transmission and led moving tooth above the paper gear, the substitute is fairly simple paper guiding roll, filter paper does not just need to punch again like this, reduces workload, processes more convenient yet; 3. removed 3 old-fashioned transmission gears, filter paper is reduced to 55 present mm wides by 65 original mm wides, has made things convenient for the filter paper loading and unloading, has reduced the use of consumable material simultaneously; 4. the distance of measuring the filter paper transmission is taken turns in the range finding of adopting filter paper to drive, does not have cumulative errors, and paper feed can accurately be located; 5. employing overall construction design adopts two register pin location, makes things convenient for Installation and Debugging and maintenance; 6. between probe body and chart drive assembly, increase by two insulation buckets, disturbed counting few, strengthened reliability; 7. the second road original Time delay measurement has only 3 cycles, improves back the second road Time delay measurement and both can use the measuring method in 3 cycles, can also use the measuring method in 7 cycles.
