The position of the limiting groove and the sealing edge is limited, and welding, installation and positioning of the sealing plate are facilitated.
Furthermore, a gasket made of a TPE material is fixedly arranged in the groove bottom of the limiting groove. The TPE material belongs to thermoplastic elastic plastic, and the lower limit of low temperature resistance is-50 ℃. Place the gasket that the TPE material was made at the spacing inslot, when the normal atmospheric temperature adsorbent was changed to needs, the manual work was removed the shrouding cutting, can avoid the banding to bond in the cell body.
Further, a mesh plate is arranged on the outer side of the filter screen, and the edge of the mesh plate is welded on the outer tank in a sealing mode.
Furthermore, the filter screens welded at the normal temperature adsorbent feeding port are multiple, and the filtering holes of the multiple filter screens are gradually reduced from outside to inside.
Compared with the prior art, the invention has simple structure, convenient manufacture and installation, stable operation and difficult damage, and the normal temperature adsorbent is directly poured into the tank body from the filling port, thereby reducing the contact time with air and prolonging the effective time of the adsorbent; only need remove the shrouding when the normal atmospheric temperature adsorbent is changed in the later stage, pour the normal atmospheric temperature adsorbent in the cell body, mend new normal atmospheric temperature adsorbent can, change in-process convenience, swift, labour saving and time saving.
