when the industrial gas cooling device works, the industrial gas after being roughly separated by the thermal drying mechanism 500 simultaneously enters the six groups of gas cylinders 110 through the shunt tubes 380, the cooling operation is carried out on the interior of the gas cylinders 110 when the refrigerating tubes 140 work, the industrial gas in the gas cylinders 110 is cooled and condensed into ice crystals which are attached to the inner walls of the gas cylinders 110 and the temperature guide plates 150, and the moisture in the industrial gas is cooled and separated;
when the ice crystal cleaning machine works, the first servo motor 162 is electrified and started to drive the screw rod 161 fixed on the rotating output shaft to rotate, the threaded sleeve 163 moves up and down on the screw rod 161 under the driving of the meshing of the threads, so that the scraping frame 164 is driven to move on the air storage cylinder 110 and the temperature guide plate 150, ice crystals condensed and attached inside the air storage cylinder 110 are hung downwards and fall into the drawer 166, and a worker can take out the drawer 166 through drawing after working is finished, so that the ice crystals inside the drawer are cleaned;
when the gas storage cylinder 110 works, after the second servo motor 360 is powered on and started, the gear 370 fixed on the rotating output shaft of the second servo motor is driven to rotate, the inner toothed ring 350 drives the ring sleeve 330 to rotate through the meshing transmission of teeth between the gear 370 and the inner toothed ring 350, the guide tubes 340 are continuously rotated under the relative rotation between the ring sleeve 330 and the fixed ring 310, and are sequentially connected and communicated with the six groups of the conduction ports 320, so that the six groups of the gas storage cylinders 110 are controlled to be respectively exhausted or closed, and the dried gas in the gas storage cylinders 110 passes through the exhaust pipes 130 and the conduction ports 320 and is led out from the exhaust pipes 390 through the guide tubes 340.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
