Technical field:
The utility model relates to the drying machine technical field, relates in particular to the no hot dehumidifying heat pump that is used for engineering plastics.
Background technology:
Engineering plastics such as Nylon, PC, PET etc., hygroscopicity is all more intense, and conditions such as its hygroscopicity and air humidity are closely related.If the moisture content of engineering plastics is too high, can have a strong impact on the quality of product, therefore, dehumidification treatments is one important procedure in the engineering plastics processing, existing dehumidification equipment is generally air drier.The traditional heated air drying machine is made up of dry charging basket, drying air fan and dry electric heating portion, and it generally can only reach 10 ℃ dew point, because the dew point height, effect on moisture extraction is not good, is used in the engineering plastics that dry service condition is not high or moisture content is low only.Also have use on traditional heated air drying machine basis improved rotary wheel dehumidifying drying machine as dehumidification equipment, this rotary wheel dehumidifying drying machine utilizes that moisture content reduces dew point in the honeycomb runner absorbed air, the dry wind of low dew point below sustainable the providing-40 ℃, effect on moisture extraction improves greatly, but rotary wheel dehumidifying drier structure complexity, energy consumption height, maintenance cost height, and can discharge hot gas and plastic contaminant, cause environmental pollution.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, a kind of no hot dehumidifying heat pump is provided, this no hot dehumidifying heat pump dew point is lower, can improve effect on moisture extraction, and is simple in structure, maintenance cost is lower, hot blast is recyclable, saves the energy, cuts down the consumption of energy, no hot gas and dust are discharged, and help reducing environmental pollution.
For achieving the above object, the utility model is achieved through the following technical solutions: do not have hot dehumidifying heat pump, comprise dry charging basket, drying air fan and dry electric heating portion, the air outlet of drying air fan connects the air inlet of dry electric heating portion, the air outlet of drying electric heating portion connects the air inlet of dry charging basket, also comprise air compressor, recursive filter and heatless regeneration air dryer, air compressor connects the inlet of heatless regeneration air dryer, the outlet of heatless regeneration air dryer connects the air inlet of drying air fan, and described recursive filter is connected between the air inlet of the air outlet of dry charging basket and drying air fan.
Be connected with fore filter between the inlet of described air compressor and heatless regeneration air dryer.
Be connected with post-filter between the outlet of described heatless regeneration air dryer and the air inlet of drying air fan.
Described dry charging basket is provided with the hydrofuge filter.
The utility model beneficial effect is: the utility model comprises dry charging basket, drying air fan, drying electric heating portion, air compressor, recursive filter and heatless regeneration air dryer, after dehumidifying, the pressure-air that the heatless regeneration air dryer provides air compressor forms high pressure dry air, the air that recursive filter is discharged dry charging basket filters to form and reclaims air, high pressure dry air enters drying air fan after air mixes with reclaiming, add thermosetting high temperature drying air through super-dry electric heating portion then, the high temperature drying air carries out desiccant dehumidification to engineering plastics again in dry charging basket handles.The heatless regeneration air dryer utilizes the transformation absorption principle to come dried compressed air, and regenerative process need not electric heating, and power consumption is low, and can make pressure-air reach lower dew point, and air compressor all has outfit in general factory, simple to operate, therefore, it is lower to the utlity model has dew point, can improve effect on moisture extraction, simple in structure, maintenance cost is lower, and hot blast is recyclable, save the energy, cut down the consumption of energy, no hot gas and dust are discharged, and help reducing the advantage of environmental pollution.
Description of drawings:
Fig. 1 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 1, there is not hot dehumidifying heat pump, comprise dry charging basket 8, drying air fan 6 and dry electric heating portion 7, the air outlet of drying air fan 6 connects the air inlet of dry electric heating portion 7, the air outlet of drying electric heating portion 7 connects the air inlet of dry charging basket 8, also comprise air compressor 1, recursive filter 4 and heatless regeneration air dryer 3, air compressor 1 connects the inlet of heatless regeneration air dryer 3, the outlet of heatless regeneration air dryer 3 connects the air inlet of drying air fan 6, and described recursive filter 4 is connected between the air inlet of the air outlet of dry charging basket 8 and drying air fan 6.Be connected with fore filter 2 between the inlet of described air compressor 1 and heatless regeneration air dryer 3.Be connected with post-filter 5 between the air inlet of the outlet of described heatless regeneration air dryer 3 and drying air fan 6.Described dry charging basket 8 is provided with hydrofuge filter 9.
During work, the air compressor 1 that factory is equipped with provides pressure-air, pressure-air enters heatless regeneration air dryer 3 through behind the fore filter 2, behind the aqueous vapor filtering, dehumidifying systemic effect of heatless regeneration air dryer 3, become high pressure dry air, high pressure dry air is through behind the post-filter 5, air inlet by drying air fan 6 enters drying air fan 6, this moment, high pressure dry air blew the dry electric heating portion 7 that enters by drying air fan 6,7 pairs of high pressure dry airs of dry electric heating portion carry out heat temperature raising, form the high temperature drying air, and blow to the engineering plastics that are positioned in the dry charging basket 8, realize purpose to the engineering plastics heating, drying.In the dehumidification treatments process of engineering plastics heating, drying, air can be carried the impurity and the moisture of engineering plastics secretly, behind the hydrofuge filter 9 discharge section moisture of this air drying charging basket 8, move to from dry charging basket 8 air outlets and to carry out contaminant filter and air the recursive filter 4 and reclaim, this moment, the relative humidity of air was lower than atmosphere, and temperature is than atmosphere height, the air after the recovery with enter drying air fan 6 after high pressure dry air mixes, realize recycling.Because heatless regeneration air dryer 3 utilizes the transformation absorption principle to come dried compressed air, regenerative process need not electric heating, power consumption is low, and can reach the low dew point below-40 ℃, can significantly improve effect on moisture extraction, can reduce the moisture content of raw material greatly, avoid the moulding product to occur shrinking, technological problems such as crazing or indenture, and air compressor 1 all has outfit in general factory, simple to operate, therefore, it is lower to the utlity model has dew point, can improve effect on moisture extraction, simple in structure, maintenance cost is lower, hot blast is recyclable, saves the energy, cuts down the consumption of energy, no hot gas and dust are discharged, and help reducing the advantage of environmental pollution.
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.
