Abstract
The utility model provides a pump-suction type active carbon box used for testing soil radon. The active carbon box comprises an upper cover, a cylinder body, an air inlet nozzle, an air outlet nozzle, a screw and a sealing ring. After the active carbon is loaded into the box, the upper cover is screwed tightly, the screws of the air inlet nozzle and the air outlet nozzle are opened, a hose is connected with the air inlet nozzle, an air taking device of soil radon and an air pump, and then the air pump is started to pump air; after air pump is finished, the air inlet nozzle and the air outlet nozzle are screwed tightly again.
Description
Technical field
The utility model relates to the measurement of radon in the radiomaterial, especially for the activated charcoal of the measurement of radon in the soil.
Background technology
When charcoal absorption measured soil radon, activated charcoal is placed in certain device, place soil the absorption of radon to be used for the radon concentration of measured soil by activated charcoal by certain hour.Conventional device is generally plastic casing or can, and top is that screw top, bottom are cylindrical shell, and activated charcoal is placed box, during absorption box is embedded in the soil, and the absorption back is taken out and then measured.Mainly by Static Adsorption, adsorption time is long, is subjected to the influence of natural conditions (temperature, humidity, air pressure etc.) easily when the absorption radon for existing activated charcoal device.
Summary of the invention
The utility model provides a kind of activated charcoal that is used for the measured soil radon of pump suction type.
Realize the technical solution of the utility model: a kind of activated charcoal, comprise the screw top on top and the cylindrical shell of bottom, be characterized in that the centre of screw top is provided with admission piece, there is the screw of O-ring seal and screw type the upper end of admission piece; The centre of cylindrical shell is provided with outlet nozzle, and there is the screw of O-ring seal and screw type the lower end of outlet nozzle.
Effect of the present utility model: the utility model by lid and box at the bottom of and form into and out of valve, loam cake can screw out, and is used for the medium activated charcoal that upside-down mounting is used to adsorb radon, is used for extracting the gas of soil into and out of valve at the bottom of lid and the box.
Accompanying drawing and explanation
Fig. 1 measures with activated charcoal photo figure for Soil Radon;
Fig. 2 measures for Soil Radon and uses the activated charcoal structural representation.
Embodiment
As shown in FIG., this activated charcoal comprises the screw 5 of screw top 1, cylindrical shell 2, admission piece 3, outlet nozzle 6, O-ring seal 4 and screw type.Activated charcoal is packed into behind this box, loam cake is tightened, open the screw into and out of valve, connect the collector and the air pump of admission piece and Soil Radon with flexible pipe, start air pump then and bleed, bleeding finishes again screwing down into and out of valve.
The diameter of activated charcoal is 7.5 centimetres, highly is 2.5 centimetres; The diameter of admission piece 3 and outlet nozzle 6 is 10 millimeters, and length is 15 millimeters.
