Description
Technical field
The utility model relates to a kind of compressed-air drier.
Background technology
At present, keep dry the mode of at present using time-delay relay to release in order to make in the pipeline; But can cause part moisture to get in the export pipeline because the variation of ambient humidity cause releasing untimely, cause that the later stage evaporates once more; It is big that humidity becomes, and drying capacity reduces, and causes that simultaneously the heat exchange of evaporimeter is not enough; Compressor causes liquid hammer easily, has reduced service life, and involves great expense.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency, a kind of simple in structure, with low cost, compressed-air drier timely, that disposal ability is strong of releasing to be provided.
The purpose of the utility model realizes through following technical scheme: a kind of compressed-air drier, comprise compressor, and an end of compressor links to each other with an end of condenser through pipeline; The other end of condenser links to each other with an end of device for drying and filtering through pipeline; The other end of device for drying and filtering links to each other with an end of expansion valve through pipeline, and the other end of compressor links to each other with evaporimeter one end through pipeline, and the other end of evaporimeter links to each other with the other end of expansion valve through pipeline; End near evaporimeter is provided with the expansion valve sensor; The expansion valve sensor links to each other with expansion valve, is provided with air inlet and air outlet in the evaporimeter, and the air outlet place is provided with liquid-level switch; The bottom of evaporimeter is connected with outlet pipe, and outlet pipe is provided with magnetic valve.
The further improvement of the utility model is: be provided with temperature sensor in the evaporimeter, the temperature sensor temp sensor device outside with placing evaporimeter links to each other.
The further improvement of the utility model is: the place is provided with blower fan near condenser, and blower fan links to each other with motor.
The utility model compared with prior art has the following advantages: the utility model utilizes refrigeration system cooling air, thereby make its temperature under operating pressure reach dew-point temperature airborne steam is freeze-outed, and reaches dry purpose.The control mode of time-delay relay is changed into liquid-level switch control, not influenced by ambient humidity, release in time, disposal ability strengthens, and the protection compressor increases the liquid level warning function simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Label among the figure: 1-compressor, 2-condenser, 3-device for drying and filtering, 4-expansion valve, 5-evaporimeter, 6-expansion valve sensor, 7-air inlet, 8-air outlet, 9-liquid-level switch, 10-outlet pipe, 11-magnetic valve, 12-temperature sensor, 13-temp sensor device, 14-blower fan, 15-motor.
The specific embodiment:
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment of the utility model compressed-air drier like Fig. 1, comprise compressor 1, an end of compressor 1 links to each other with an end of condenser 2 through pipeline; The other end of condenser 2 links to each other with an end of device for drying and filtering 3 through pipeline, and the other end of device for drying and filtering 3 links to each other with an end of expansion valve 4 through pipeline, and the other end of compressor 1 links to each other with evaporimeter 5 one ends through pipeline; The other end of evaporimeter 5 links to each other with the other end of expansion valve 4 through pipeline, is provided with expansion valve sensor 6 near an end of evaporimeter 5, and expansion valve sensor 6 links to each other with expansion valve 4; Be provided with air inlet 7 and air outlet 8 in the evaporimeter 5; Air outlet 8 places are provided with liquid-level switch 9, and the bottom of evaporimeter 5 is connected with outlet pipe 10, and outlet pipe 10 is provided with magnetic valve 11; Be provided with temperature sensor 12 in the evaporimeter 5; Temperature sensor 12 links to each other with placing evaporimeter 5 outside temp sensor devices 13, and 2 places are provided with blower fan 14 near condenser, and blower fan 14 links to each other with motor 15.
Compressor is compressed to cold-producing medium in the condenser, and cold-producing medium is condensed into liquid state in condenser, and blower fan is in the other work of condenser; Quicken condenser condenses, condensed liquid refrigerant gets in the device for drying and filtering and carries out dry filter, gets into expansion valve afterwards; Expansion valve comes the temperature of control evaporimeter in real time according to the temperature of the evaporimeter that the expansion valve sensor measures, and air gets into the evaporimeter from air inlet, after air is condensed, just has water-setting and bears; After water was run into liquid-level switch, magnetic valve will be opened, and water flows out along outlet pipe; Temperature sensor is used for detecting the temperature in the evaporimeter; Temperature in evaporimeter is higher than dew-point temperature, and temperature sensor will send signal to temp sensor device, and temp sensor device can give the alarm.
The utility model utilizes refrigeration system cooling air, thereby make its temperature under operating pressure reach dew-point temperature airborne steam is freeze-outed, and reaches dry purpose.The control mode of time-delay relay is changed into liquid-level switch control, not influenced by ambient humidity, release in time, disposal ability strengthens, and the protection compressor increases the liquid level warning function simultaneously.
