The cooler includes at least an evaporator of the refrigerating device, the entering and exiting tubes of which are communicated with the cooling agent of the air conditioner outdoor device. The packaged freezing dehydrator is characterized by simple structure, reasonable and compact design, convenient use and set-up, improvement of the product quality, simplification of the manufacturing technique, reduction of the producing circle, decreased producing cost or the like.

Description

The assembly type freeze drier
Technical field
The utility model relates to a kind ofly, air is carried out dry equipment, especially compressed air is carried out dry equipment according to principle refrigeration.
Background technology
At present, at oil, chemical industry, telecommunication, electric power, weave, spray paint, industry such as medicine, cigarette, food, metallurgy, communications and transportation, glass, machine-building need use drying machine that compressed air is carried out drying, and the drying machine that is adopted mostly is freezing type drier, it mainly is made up of compressed air heat-exchange device and refrigerating plant two parts, shown in accompanying drawing 1, compressed air is introduced into precooler 13 and cools off, to adapt to megathermal compressed air, it is cooled to 40 ℃ with high temperature compressed air; Hot and moist compressed air enters forecooler 12 again, with carry out heat exchange from cooler 11 dryings, chilled compressed air, reduce compressed-air actuated saturation temperature, remove a little moisture content, enter cooler 11 again, make compressed air be cooled to about 1.7 ℃ of pressure leak sources, moisture content and partial impurities are solidified at this, through the separation of spiral gas separating device, deposition such as moisture content and impurity is discharged through electromagnetism water trap 15; Described cooler 11 comes down to the evaporimeter of a refrigerating plant, the low temperature liquid cold-producing medium flows to cooler 11 through pipeline, absorb a large amount of heats and flash to gaseous state, the cold-producing medium of gaseous state enters vaporizer 10 from cooler 11 outlets, treat to enter after micro-liquid refrigerant is vaporized fully the air entry of cold medium compressor 1 within it, cold medium compressor 1 is compressed into high temperature and high pressure gas with the gaseous refrigerant of low-temp low-pressure, autoregulation by hot gas bypass valve 7, have fraction gas directly to enter cooler 11, most of gas then enters water cooled condenser 5 or air cooled condenser condensation and cooling; The high pressure low temperature liquid refrigerant that comes out from condenser enters the heating power expansion valve 8 by the throttling step-down by device for drying and filtering 6, becomes low pressure liquid and enters cooler 11, and cooling has entered the compressed air of cooler through shell side.The effect of above-mentioned device for drying and filtering 6 is trace water and pollutants of removing in the cold-producing medium, and circulation so goes round and begins again.Cooling driers of the prior art can according to load and variation of ambient temperature automatic regulating system energy cooler 11 in refrigerant temperature raise, heating power expansion valve is regulated in the signal transmission of the sensor by heating power expansion valve automatically, up to reaching new balance.When the too small evaporating temperature of the load of cold dried chicken descends, heating power expansion valve closes minor valve automatically, hot gas bypass valve 7 automatically provides a load to cooler 11 simultaneously, to guarantee the stable of evaporating temperature, the stifled phenomenon of the device that avoids evaporating ice takes place, and guarantee the inspiratory capacity of compressor, make the cooling driers can operate as normal.The effect of the high and low voltage switch of installing in the system 9 is: when refrigerating plant occur to leak or condensing unit heat radiation etc. bad, low pressure occurs and cross low or high pressure when too high, the 1 unlikely damage of protection cold medium compressor.But the cooling driers that said structure is formed, each parts in its refrigerating plant are installed and are disperseed, processing technology is loaded down with trivial details, the processing duration is longer, manufacturing cost height, particularly copper pipe welding procedure are difficult to control, are difficult to guarantee the cleaning of refrigeration piping, cause that easily refrigeration compressor damages or device for drying and filtering stops up, thereby increase fault rate.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of production quality that can improve, simplify production technology, shorten the production cycle, reduce the assembly type freeze drier of manufacturing cost, it mainly is made up of heat exchange device for air and refrigerating plant, and described heat exchange device for air is made of a forecooler and cooler at least, and cooler is matched by at least two copper pipes and an air-conditioner outdoor unit.
The heat exchanger that described forecooler is at least a water-cooled heat exchanger or carries out heat exchange with compressed air after the cooler cooling.Described cooler is made of the evaporimeter of refrigerating plant at least, and the import and export pipeline of evaporimeter is imported and exported pipeline with the cold-producing medium of air-conditioner outdoor unit respectively and directly connected.
The utility model utilizes the air-conditioner outdoor unit group of technology maturation, stable performance to replace original refrigerating plant, can directly simplify the processing technology of original refrigerating plant complexity, freezing type drier is divided into heat exchange device for air and air-conditioner outdoor unit two big parts simply, and carries out simple copper pipe and connect; Have simple and reasonable for structurely, compactness is used, easy for installation, improves the production quality, simplifies production technology, shortens the production cycle, reduces characteristics such as manufacturing cost.
Description of drawings
Fig. 1 is that prior art constructions is formed and schematic flow sheet.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the plan structure schematic diagram of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: Fig. 2, shown in Figure 3, the utility model mainly is made up of heat exchange device for air A and refrigerating plant B two big parts, described heat exchange device for air A is made of a forecooler 16 and cooler 17 at least, cooler 17 is made of the evaporimeter of refrigerating plant B, and it is matched by two copper pipes 18 and an air-conditioner outdoor unit 19.Forecooler 16 shown in the figure is a heat exchanger that carries out heat exchange with compressed air after cooler 17 cooling; In other embodiments, forecooler 16 also can be a kind of water-cooled heat exchanger or with the heat exchanger of aforesaid heat exchangers combination.
The utility model utilizes the air-conditioner outdoor unit group of technology maturation, stable performance to replace original refrigerating plant, can directly simplify the processing technology of original refrigerating plant complexity, freezing type drier is divided into heat exchange device for air and air-conditioner outdoor unit two big parts simply, and carries out simple copper pipe and connect.The technology contents that does not relate in the present embodiment is all same as the prior art or directly can derive, and because of the utility model belongs to improvement to prior art, thereby those skilled in the art can carry out the enforcement of patented technology on the basis of the foregoing description.
