Abstract
Disclosed is a plastic raw material dryer energy-saving device which comprises a return vent pipe (20) that is arranged on a top head (10) of a dryer barrel (100), wherein, the return vent pipe (20) is communicated with a ventilation pipe (30) of a fan (200); the outer surface of the barrel (100) is covered with a barrel heat preservation quilt (40); the outer surface of the return vent pipe (20), the ventilation pipe (30) and a duct outlet (70) of the fan (200) are all covered with pipe heat preservation quilts (50); the device also comprises a heating element (60) that is arranged in the duct outlet (70); the heating element (20) is connected to the lower than 80V power supply. The device adopts residual heat utilization, low pressure power supplying and integral heat preservation technologies so the utility model is characterized by high heating efficiency, good heat preservation performance, safety and reliability, low cost and good energy saving effect.
Description
Technical field the utility model relates to firing equipment, particularly the heating and heat-insulating device on the plastic raw materials dryer.
Background technology
On overall structure, the dryer of prior art is discharged by exhaust duct at dried waste heat, be not used, and monolithic case does not all add insulation, and heat scatters and disappears bigger, and these two kinds of factors are to cause the serious major reason of the former technomania loss of energy.
Conventional heating technique is to adopt the heating of power-frequency voltage total head, because heating voltage and temperature are higher, to having relatively high expectations of insulating barrier, generally use high-quality mica sheet or pottery, quartz sand as the partiting thermal insulation material, higher and the complex process of cost, and because what carry out is the heating of golden voltage, heating-up temperature is more than 800 ℃, the insulating materials of electrothermal device more easily produces electrical breakdown, thermal ablation phenomenon, greatly reduces the reliability of electric heater unit.In addition, the heating wire diameter of routine techniques is less, heating-up temperature is higher, add the reason of conventional total head heating wire owing to manufacturing process and metallurgical technology, diameter is little, length is big having, and it is inhomogeneous easily to produce the heat radiation that causes on the inhomogeneous and manufacture craft of resistance, very easily produces the factors such as localized heat ablation, high-temperature oxydation of heating wire, very easily cause the damage of heating element heater, make heating element heater influence drying effect because of quality is unreliable.
Summary of the invention the utility model makes full use of waste heat after the oven dry heating and heats once more and cooperate whole fully insulation measure, and it is low to have solved in the prior art thermal efficiency, the technical problem of the serious and heating element heater of energy waste; Adopt the low pressure heating technique, further solve heating element heater insulating requirements height in the prior art, the technical problem of cost increase and easy electrical breakdown.
The utility model is realized by implementing following technical scheme: a kind of plastic raw materials dryer energy saver, this device comprises and is arranged at the backwind tube that covers on the dryer barrel, this backwind tube one end is communicated with the feed bin of barrel, and the other end is communicated with the blast pipe of air blast.Described barrel outer surface be coated with the barrel insulation quilt, the outer surface of the discharge pipe of described backwind tube, blast pipe and air blast all is coated with the pipeline heat insulation quilt.The waste heat pipe at oven dry barrel top is connected on the air blast blast pipe by backwind tube, the waste heat air is carried out drying again and heats, improve the EAT of air blast, can energy savings.Barrel and each airduct are incubated processing, prevent that heat scatters and disappears, and can make full use of heat energy.
This device also comprises the heating element heater that places in the discharge pipe, the control of the controlled system of this heating element heater, and described heating element heater is connected on 80 volts of following power supplys, and the sectional area of described heating element heater is not less than 5mm
2Owing to adopt the low-voltage power supply scheme, the corresponding increase of diameter that can make heating element heater is more than tens times, heating current increases more than tens times, makes effective area and the diameter increase and the length minimizing of heating element heater, adds the low-temperature heat technology of taking, heating surface (area) (HS is increased, heat more evenly, it is anti-ablates, antioxygenic property greatly strengthens, and prolonged its service life greatly, under the condition of making material and technological requirement strictness, its heating element heater can accomplish substantially 10 years non-maintaining.
This device has adopted UTILIZATION OF VESIDUAL HEAT IN, low-voltage power supply and integral heat insulation technology, so, efficiency of heating surface height, good heat insulating, have safe and reliable, cost is low, the characteristics of good energy-conserving effect.
Description of drawings
Fig. 1 is that the master of the utility model plastic raw materials dryer energy saver looks partial schematic sectional view.
The specific embodiment further describes embodiment of the present utility model below in conjunction with accompanying drawing.
By finding out among Fig. 1, a kind of plastic raw materials dryer energy saver, this device comprise the backwind tube 20 that is arranged on dryer barrel 100 loam cakes 10, and these backwind tube 20 1 ends are communicated with the feed bin of barrel 100, and the other end is communicated with the blast pipe 30 of air blast 200.The waste heat pipe at oven dry barrel 100 tops is connected on air blast 200 blast pipes 30 by backwind tube 20, the waste heat air is carried out drying again and heats, improve the EAT of air blast 200, can energy savings.
By can finding out among Fig. 1, described barrel 100 outer surfaces be coated with barrel insulation quilt 40, the outer surface of the discharge pipe 70 of described backwind tube 20, blast pipe 30 and air blast 200 all is coated with pipeline heat insulation by 50.Barrel 100 and each airduct are incubated processing, prevent that heat scatters and disappears, and can make full use of heat energy.
By finding out among Fig. 1, this device also comprises the heating element heater 60 that places in the discharge pipe 70, this heating element heater 20 controlled systems control, and described heating element heater 20 is connected on 80 volts of following power supplys, and the sectional area of described heating element heater 60 is not less than 5mm
2Owing to adopt the low-voltage power supply scheme, the corresponding increase of diameter that can make heating element heater 60 is more than tens times, heating current increases more than tens times, makes effective area and the diameter increase and the length minimizing of heating element heater 60, adds the low-temperature heat technology of taking, heating surface (area) (HS is increased, heat more evenly, it is anti-ablates, antioxygenic property greatly strengthens, and prolonged its service life greatly, under the condition of making material and technological requirement strictness, its heating element heater can accomplish substantially 10 years non-maintaining.
