Particulate filter arrangement, cooling evaporator and cold retracting device composition three layer filtration, fluid tube upper and lower side has the temperature difference, the more close condenser pipe in the upper end of return duct, upper end temperature is lower, and therefore part air forms liquid state and is back to and connects in liquid bucket in the time arriving the upper end of return duct.
In above-mentioned a kind of freezing type gas drier, described forecooler upper end is connected with the lower end of cold retracting device.
In above-mentioned a kind of freezing type gas drier, the body that described condenser pipe part is placed in cooling evaporator and cold retracting device is snakelike bending structure, and the condenser pipe height of snakelike bending and the inner chamber height of cooling evaporator and cold retracting device corresponding.Augmenting response area, strengthens cooling effect.
In above-mentioned a kind of freezing type gas drier, described gas siphunculus pitch of the laps in forecooler, at cooling evaporator outer wall, is helical structure.Augmenting response area, strengthens cooling effect.
In above-mentioned a kind of freezing type gas drier, the bottom of described cold retracting device is provided with hydrops bottle, and hydrops bottle and cold retracting device removably connect.Small part liquid in cold retracting device is wandered, and hydrops bottle can be collected a small amount of liquid, without frequent tapping, therefore when a certain amount of, dismantles discharge opeing.
Compared with prior art, this device has been cut down airborne moisture, grease and particle greatly by three layer filtration, utilizes the cold isolation technics of multilayer that liquid vapour is separated more thorough, and drying effect is better.

In figure, 1, particulate filter arrangement; 2, gas siphunculus; 3, return duct; 4, connect liquid bucket; 5, condenser pipe; 6, compressor; 7, condenser; 8, liquid outlet switch; 9, fluid tube; 10, hydrops bottle; 11, dry interlayer; 12, cold retracting device; 13, recovery tube; 14, forecooler; 15, cooling evaporator.
Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this freezing type gas drier comprises that gas siphunculus 2, a periphery are linked in sequence and forms condenser pipe 5, cooling evaporator 15, forecooler 14 and the cold retracting device 12 in loop.Cooling evaporator 15 is airtight to be set in forecooler 14, be provided with and connect liquid bucket 4 in the bottom of cooling evaporator 15, connect liquid bucket 4 and be funnel-form, the bottom that connects liquid bucket 4 is provided with the liquid outlet switch 8 of controlling fluid, cooling evaporator 15 and connecing between liquid bucket 4 by fluid tube 9 conductings, fluid tube 9 bottom bifurcateds, are separately provided with return duct 3 straight up, and return duct 3 upwards one end leads in forecooler 14 and more close condenser pipe 5.The upper end of forecooler 14 is connected with cold retracting device 12 lower end pipes, be provided with dry interlayer 11 in the inside of cold retracting device 12, upper end is provided with recovery tube 13, condenser pipe 5 part bodys are placed in cooling evaporator 15 and cold retracting device 12 and are snakelike bending structure, condenser pipe 5 height of snakelike bending are corresponding with the inner chamber height of cooling evaporator 15 and cold retracting device 12, condenser pipe 5 in cold retracting device 12 is through dry interlayer 11, and the bottom of cold retracting device 12 is also provided with a hydrops bottle 10 removably connecting.
The air inlet head of gas siphunculus 2 is provided with particulate filter arrangement 1, and gas siphunculus 2 is placed in forecooler 14 with spiral form along cooling evaporator 15 outer walls, and the other end of gas siphunculus 2 passes in cooling evaporator 15.
Described condenser pipe 5 is provided with compressor 6 and condenser 7, in condenser pipe 5, be built-in with refrigerant, refrigerant circulates in condenser pipe 5, the air implementation heat exchange that the refrigerant of circulation is used for and passes into, airborne water vapour and oily vapour are cooled to liquid state, therefore the temperature of refrigerant can change, and need to be compressed with condenser 7 and again freeze by compressor 6.Refrigerant flows to cooling evaporator 15 directions from cold retracting device 12 in condenser pipe 5.
The air passing into is first by particulate filter arrangement 1 filtering particulate matter, then enter gas siphunculus 2, in forecooler 14, cooling becomes liquid to heat exchange in cooling evaporator 15 more in advance, the liquid forming gathers liquid outlet switch 8 places by fluid tube 9, the gas of vapor-liquid separation is led to the inner chamber of forecooler 14 by return duct 3 for the first time, and return duct 3 outlets are now near condenser 7, and its temperature is lower, also can reflux to the condensation of gas of pass-out, ensure that gas is dry.The gas of forecooler 14 inner chambers is flowed into the lower end of cold retracting device 12 by its forecooler 14 upper ends, because gas directly contacts the condenser pipe 5 in cold retracting device 12, therefore in gas small part water vapour again condensation enter in hydrops bottle 10, gas upwards enters recovery tube 13 again by dry interlayer 11, realizes the object of the air that extracts dry decontamination.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
