Abstract

The utility model relates to an air drying machine. A heat exchanger of the air drying machine is sheathed with a spiral dryer. The spiral dryer is provide with an air guide tube whose opening in the lower part can guide the air out of a casing in the center of the drum-shaped casing. The periphery of the air guide tube is provided with a continuous spiral baffle plate from top to bottom. A coolant tube spirals upward from the bottom following the air guide tube. A gap is reserved between the spiral baffle plate and the internal side of the casing to form a drainage ditch. When the damp air enters the spiral dryer, the condensed moisture and the fine particle of the greasy dirt are thrown to the ditch wall of the drainage ditch and flow downward because of the centrifugal force action. Thus, the moisture in the air and the greasy dirt can be separated together to obtain the clean dried air.

Description

Air drying machine

The utility model relates to a kind of dried-air drier that improves structure.

A kind of structure of dried-air drier commonly used as shown in Figure 1, it utilizes refrigerant 11 that the moisture content condensation in the humid air is got off, make again air and condensed moisture from and obtain dry air, wherein, refrigerant 11 circulates in refrigerant pipe 12 loops of a sealing, refrigerant 11 is through flow through after compressor 13 compressions condenser 14 and a coolant drying device 15, again by flowing back in the compressor 13 after the heat exchanger 18, on stream by radiator fan 17 to its heat radiation and by the pressure of pressure-control valve 16 control refrigerants 11, after humid air enters heat exchanger 18 by air intake 181, be subjected to the effect condensation of refrigerant 11 to go out moisture content, this moisture content meeting and air mix, when the air outlet slit 182 above over-heat-exchanger 18, just water is discharged by automatic water trap 19, and the part air still mixes with particulate moisture content and greasy dirt and takes out of, thereby can't obtain clean dry air fully, and this is the desirable not to the utmost part of dried-air drier commonly used.

The purpose of this utility model is to overcome above-mentioned shortcoming, proposes a kind of improved dried-air drier, to obtain clean dry air.

The dried-air drier that the utility model proposes comprises the parts that refrigerant circulates in the refrigerant tube loop of a sealing: compressor, condenser, coolant drying device, pressure-control valve and heat exchanger.Refrigerant is through a condenser and the coolant drying device of flowing through after the compressor compresses, and by radiator fan to its heat radiation and by the pressure of pressure-control valve control refrigerant, it is characterized in that: it also comprise one with the sheathed spiral dryer of heat exchanger, this spiral dryer is a lower ending opening to be set and the air conduit of the conducting that makes progress in the center of a round barrel shape enclosure interior, and in the from top to bottom continuous helical baffle plates of the periphery of air conduit setting, to form spiral helicine air duct, the refrigerant pipe follow air duct the air conduit periphery by under spiral up, still leave slightly little gap between helical baffle plates and the housing inboard to form the gutter, the bottom of housing becomes coniform and is provided with a discharge outlet, housing top side is provided with the air intake that is connected with air duct, this air intake place also is provided with air compressor, and the housing top is provided with an air outlet slit that is communicated with air conduit.

Details are as follows to the utility model below in conjunction with preferred embodiment and accompanying drawing, wherein:

Fig. 1 is the structure chart of existing dried-air drier;

Fig. 2 is the structure chart of the utility model dried-air drier;

Referring to Fig. 2, part-structure of the present utility model is identical with the dust head, circulate in refrigerant pipe 12 loops of sealing as refrigerant 11, refrigerant 11 is through flow through after compressor 13 compressions condenser 14 and a coolant drying device 15, wherein, by radiator fan 17 to its heat radiation and by the pressure of pressure-control valve 16 control refrigerants 11.The utility model and dried-air drier commonly used maximum different be refrigerant 11 by the directed stream of refrigerant pipe 12 through a spiral dryer 20, this spiral dryer 20 is a lower ending opening to be set and the air conduit 22 of the conducting that makes progress in the center of a round barrel shape housing 21 inside, the periphery of air conduit 22 is provided with from top to bottom continuous helical baffle plates 23, to form spiral helicine air duct, and refrigerant pipe 12 follow this air duct air conduit 22 peripheries by under spiral up, still leave slightly little gap between helical baffle plates 23 and housing 21 inboards forming gutter 24, for the moisture of condensation to dirty; The bottom of housing 21 becomes coniform and is provided with a discharge outlet 25, discharge outlet 25 is connected with an automatic water trap 19 again, so that draining automatically, housing 21 top sides are provided with the air intake 211 that is connected with air duct, and be provided with air compressor 30 in air intake 211 places, so that to entering the air pressurized of spiral dryer 20, housing 21 tops are provided with an air outlet slit 212 that is connected with air conduit 22, discharge thus through dried cleaned air.

When humid air enters spiral dryer 20 by air intake 211, by the moisture content condensation of the refrigerant 11 in the refrigerant pipe 12 with humid air, and exerting pressure through air compressor 30, make air and moisture content in the air duct that helical baffle plates 23 is divided into, become the circulation of whirlpool shape, at this moment, moisture content particulate and greasy dirt particulate promptly get rid of furrow bank to tubular gutter 24 because of action of centrifugal force, and to dirty, so, moisture content and greasy dirt are via layer by layer condensation, separation layer by layer also flow to the bottom of spiral dryer 20 downwards, then by automatic water trap 19 with its discharge, and the clean dry air that separates through moisture content and greasy dirt is entered by the below of air conduit 22, is discharged by the air outlet slit 212 of its top again.

In sum, the utility model has overcome dried-air drier commonly used can't be with the shortcoming of greasy dirt and air separation, and real is a kind of product that has novelty and practicality.
