Oxygen recovery device

[0020]Example

[0021]Such asFigure 1 - Figure 3As shown, the present invention provides an oxygen recovery device.

[0022]Including the processing tank 1, a blower 2 provided on the lower end of the processing box 1, the air opening of the blower 2 is connected to the oxygen source through the pipe, and the air opening of the blower 2 communicates through the intake pipe 3 to the treatment tank 1. Inside the wall, the inner side wall of the treatment tank 1 is detachably disposed, the baffle includes a first baffle 4, a second baffle 5, and the first baffle 4 located in the second. Above the baffle 5, the first baffle 4, the second baffle 5 constitutes a purification chamber 6, and the purified cavity 6 is filled with graphite carbon, the first baffle 4, a second baffle. 5 all throughout the through hole 7, the through hole 7 is provided with a gas permeable film 72, and the through hole 7 is provided with a convex ring 71 for mounting the gas permeable membrane 72, and the gas permeable film 72 is bonded to rotate. On the ring 71, two breathable films 72 are provided in each of the through holes 7, and the gas permeable film 72 is bonded to the left and right sides of the convex ring 71, respectively, and the two permeable membrane 72 are semi-circular and Interlaced is on the convex ring 71, it is very convenient to achieve the mounting of the gas permeable film 72, which can stabilize the gas permeable membrane 72 and the through hole 7, avoiding the permeable film 72 from the through hole 7, The gas permeable film 72 is arranged to be semi-circular, and the interleave is provided in the through hole 7, which can ensure the flow rate of the airflow in the through hole 7,

[0023]An exhaust pipe 8 is provided on the upper end of the treatment tank 1, and a recovery box 9 is provided on one side, the recipient box 9 communicates with the treatment tank 1 through the exhaust pipe 8, the recipient box The evaporating dish 10 is provided, and the side wall of the recipient box 9 is provided with a refrigerator 11, and the refrigerator 11 is coupled to the evaporator 10 to reduce the temperature in the recovery box 9, the recovery box. 9 The upper end is provided with an air tube 13, and the air tube 13 communicates with a guide fan 14, which can discharge the gas in the recovery box 9 by the air tube 13, and the lower end setting of the recipient box 9 Drainage pipe 12,

[0024]The oxygen source oxygen is passed through the air blower 3 through the intake pipe 3, and the oxygen step by step is stepped through the second baffle 5, and the breathable film 72 in the through hole 7 functions as a first step in filter oxygen. Continue to rise to the purge chamber 6, graphite carbon can filter odor and harmful gases in oxygen, and oxygen further rises through the first baffle 4, the breathable film 72 on the first baffle 4 places impurities in oxygen in oxygen. After the filtered oxygen is circulated into the recovery box 9, the refrigerator 11 is activated, and the refrigerator 11 causes the evaporating dish 10 to decrease, so that the oxygen entered into the recovery box 9 is refrigerated to make oxygen. The moisture condenses into a small water droplet, and the coagulated small water droplets are dripped at the bottom of the recovery box 9 through the drain pipe 12, open the guide fan 14 switch, when the air blower 14 is activated, the introduction fan 14 will collect the recovery box through the air tube 13 The oxygen in the 9 draws out, and then transported into the oxygen tank through the pipe;

[0025]The present invention can make oxygen in addition to implicit water, improve the recovery of oxygen, in response to national energy-saving and environmental protection policies, thereby improving the production benefits of enterprises;

[0026]In order to facilitate replacement and maintenance of the equipment in the processing box 1, the upper end hinges are provided with a top cover 16;

[0027]In order to facilitate the opening and closing of the top cover 16, a handle is provided on the top cover 16 to prevent the operator's hand from slipping, and the handle is disposed on the handle;

[0028]The tank 1, the upper side wall of the recovery box 9 is provided with a window 15;

[0029]In order to facilitate more clear observations, a convex mirror is provided on the window 15;

[0030]In order to facilitate the maintenance and replacement of the equipment in the recovery box 9, the front hinges of the recipient box 9 are provided with a box door 17;

[0031]In order to facilitate the sealing of the recovery box 9 with the box door 17, the recipient box 9 is provided with a sealing layer at the junction of the box door 17, the sealing layer to prevent the temperature of the recovery box 9. Loss.
