The utility model relates to the technical field of a dryer, in particular to a desiccant dryer used for engineering plastics. The desiccant dryer comprises a circulating blower, an electric control case, a dry electric heating part, a dry charging barrel, a dehumidifier and a whirlwind dust-collecting hot air recycling machine. The non-hot type dehumidifier is arranged at the outer part of the circulating blower, a high-pressure dry air inlet hole is arranged at the circulating blower, a high-pressure air outlet and a high-pressure air inlet are arranged at the non-hot type dehumidifier, the high-pressure dry air inlet hole is connected with the high-pressure air outlet by an air guide pipe, and the high-pressure air inlet is connected with an air compressor. The desiccant dryer has the advantages that the dew point is low, the dehumidifying effect can be improved, the structure is simple, energy resources are saved, and the maintenance cost is low.
Description
Technical field:
The utility model relates to the drying machine technical field, relates in particular to a kind of desiccant dryer that is used for engineering plastics.
Background technology:
The hygroscopicity of engineering plastics is strong, and weather conditions such as its hygroscopicity and air humidity are closely related, and therefore, dehumidifying is one important procedure during plastic processing is produced.Traditional air drier is made up of electric cabinet, dry electric heating portion and dry charging basket, and it is simple in structure, and is cheap, yet traditional air drier dew point height, generally can only reach 10 ℃ dew point, effect on moisture extraction is not good, only can be used for the plastics that dry service condition is not high or moisture content is low.In order to improve effect on moisture extraction, on the basis of traditional heated air drying machine, improve out the electrothermal dehumidifying heat pump, it utilizes the effect that reclaims air dewetting to reduce dew point, low dew point dry wind below sustainable the providing-40 ℃, effect on moisture extraction improves greatly, has solved the difficult problem that the traditional heated air drying machine cann't be solved in the engineering plastics drying, but electrothermal dehumidifying heat pump structure relative complex, the power consumption height, the maintenance cost height.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, and a kind of desiccant dryer is provided, and this desiccant dryer dew point is lower, can improve effect on moisture extraction, and simple in structure, saves the energy, and maintenance cost is lower.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of desiccant dryer, comprise that circulating fan, electric cabinet, dry electric heating portion, dry charging basket, dehumidifier and whirlwind control of dust hot blast reclaim machine, described circulating fan outer setting has or not the hot type dehumidifier, circulating fan is provided with the high pressure dry air air admission hole, no hot type dehumidifier is provided with pressure-air outlet and pressure-air inlet, the high pressure dry air air admission hole is connected by air conduit with the pressure-air outlet, and the pressure-air inlet is connected with air compressor.
The utility model beneficial effect is: the utility model comprises circulating fan, electric cabinet, drying electric heating portion, dry charging basket, dehumidifier and whirlwind control of dust hot blast reclaim machine, at circulating fan outer setting one no hot type dehumidifier, after the pressure-air that no hot type dehumidifier provides air compressor is removed moisture, again pressure-air is sent into circulating fan, can reach lower dew point, and not having the hot type dehumidifier is to utilize the transformation absorption principle to come dried compressed air, regenerative process need not electric heating, power consumption is low, and air compressor all has outfit in general factory, therefore, it is lower to the utlity model has dew point, can improve effect on moisture extraction, and simple in structure, save the energy, the advantage that maintenance cost is lower.
Description of drawings:
Fig. 1 is the structural representation of traditional heated air drying machine;
Fig. 2 is the structural representation of electrothermal dehumidifying heat pump;
Fig. 3 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 3, a kind of desiccant dryer, comprise that circulating fan 1, electric cabinet 2, dry electric heating portion 3, dry charging basket 4, dehumidifier 5 and whirlwind control of dust hot blast reclaim machine 6, described circulating fan 1 outer setting has or not hot type dehumidifier 10, circulating fan 1 is provided with high pressure dry air air admission hole 7, no hot type dehumidifier 10 is provided with pressure-air outlet 9 and pressure-air inlet 11, high pressure dry air air admission hole 7 and pressure-air outlet 9 is connected by air conduit 8, and pressure-air enters the mouth and 11 is connected with air compressor.
During work, general air is compressed into pressure-air through air compressor, pressure-air enters no hot type dehumidifier 10 by pressure-air inlet 11, behind the aqueous vapor filtering, dehumidifying systemic effect of no hot type dehumidifier 10, become high pressure dry air, high pressure dry air enters high pressure dry air air admission hole 7 from pressure-air outlet 9 along air conduit 8, enter circulating fan 1 again, this moment, high pressure dry air promoted to enter dry electric heating portion 3 forward by circulating fan 1,3 pairs of high pressure dry airs of dry electric heating portion carry out heat temperature raising, air behind the heat temperature raising blows to the engineering plastics that are placed in the dry charging basket 4, realizes the purpose to the engineering plastics heating, drying.In the process of engineering plastics heating, drying, air meeting entrained plastic impurity and moisture, air part moisture when the weep hole of dehumidifier 5 is discharged from, air moves to and carries out contaminant filter and air recovery in the whirlwind control of dust hot blast recovery machine 6 afterwards, this moment, the relative humidity of air was lower than atmosphere, and temperature is than atmosphere height, and the air after the recovery enters in the circulating fan, and is recycling after mixing with high pressure dry air.Because no hot type dehumidifier 10 is to utilize the transformation absorption principle to come dried compressed air, regenerative process need not electric heating, power consumption is low, and therefore, the utility model can reach the low dew point below-40 ℃, improve effect on moisture extraction, and simple in structure, save the energy, maintenance cost is lower, can reduce the moisture content of raw material greatly, avoid the moulding product technological problemses such as shrink, crazing or indenture to occur.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
