Abstract
The utility model relates to an active carbon box for measuring atmospheric radon, which is composed of a screw cap on the upper part, a cylinder body on the lower part and a precession type screen mesh, wherein the screen mesh is composed of a circular frame, three support bars and a stainless steel mesh. The periphery of the frame is provided with screw threads, and the stainless steel mesh is fixed firmly on the frame and the support bar. The inner wall of the cylinder body on the lower part is provided with screw threads and a screen mesh fixing device which can cause the screen mesh to precess in and out. The screen mesh is used for fixing the active carbon which absorbs radon. The utility model satisfies the consistency of geometric condition during active carbon adsorption process and measurement, and ensures the accuracy of the measurement result.
Description
Technical field
The utility model relates to the measurement of radon in the radiomaterial, particularly a kind of absorption and measuring activated charcoal that is used for Environmental Radon.
Background technology
When charcoal absorption measurement environment radon, activated charcoal is placed in certain device, place surrounding air by certain hour, the absorption of radon is used for the radon concentration of measurement environment by activated charcoal.Conventional device is generally plastic casing or can, and top is that screw top, bottom are cylindrical shell, and activated charcoal is placed box, opens the lid during absorption, and absorption is tightened lid when finishing and measured then.The geometric volume and the absorption surface of existing activated charcoal activated charcoal when the device activated charcoal are wayward, influence measurement result.
Summary of the invention
The utility model provides a kind of screen cloth compressing activated charcoal by screw type before and after absorption and the activated charcoal of the geometric configuration that is consistent in the measuring process.
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 being provided with the screw type screen cloth, three plastic support bars and stainless steel cloth that screen cloth moulds material frame, star-shaped distribution by the garden are formed; The outer rim that the material frame is moulded in the garden is provided with screw thread, moulds on material frame and the plastic support bar with the method for the casting garden of being fixed on that stainless steel cloth is firm, and the inwall of bottom cylindrical shell has spiral and can make the screen cloth stationary installation of screen cloth precession, back-out.
Effect of the present utility model: the utility model is made up of activated charcoal and precession screen cloth two parts, but the screen cloth spinning in and out are used for fixing the medium activated charcoal that adsorbs radon, satisfies the consistance that reaches geometric condition in the measuring process in charcoal adsorption process.
Accompanying drawing and explanation
Fig. 1 is the measuring activated charcoal photo of Environmental Radon figure;
Fig. 2 is the measuring activated charcoal synoptic diagram of Environmental Radon.
Embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of screen cloth compressing activated charcoal by screw type before and after absorption and the activated charcoal of the geometric configuration that is consistent in the measuring process.This activated charcoal comprises loam cake 1, cylindrical shell 2, cylinder inboard wall screw thread 3 and screw type screen cloth 4.Activated charcoal is packed into behind this box, activated charcoal is shakeout, screw in screen cloth then and tighten, make screen cloth firmly oppress activated charcoal, make it to be fixed in the box, guarantee that the geometric configuration of activated charcoal in sampling process and the measuring process is not changed.
The aperture of stainless steel cloth is 2 millimeters.The diameter of activated charcoal is 10 centimetres, highly is 3 centimetres.
