Abstract
The invention is a high-temperature efficient energy-saving roller dryer, which is mainly applied to operation stages of drying, baking, curing and aging units in the industries such as food, papermaking, printing and dyeing and chemical industry. The roller dyer utilizes heat-conducting oil as medium to supply heat and has high heat efficiency; the waste liquid and exhaust gas are discharged in the work process, and can be freely adjusted between natural temperature and 350 degrees centigrade. The heat-conducting oil cokes and ages difficultly and can reach extreme value of service life. The system device is damaged difficultly, greatly reduces the maintenance cost of the device, and is efficient, energy-saving and environment-friendly.
Description
One, technical field: this is suitable for novel a kind of drying unit that relates to, relate in particular in the industries such as food, papermaking, printing and dyeing, chemical industry drying, cure, slaking, the high temperature in ageing unit operations stage, efficient, energy-conservation roller dryer.
Two, background technology: at present, the drying roller tube majority of using in the domestic food industry is to be transplanted by the drying cylinder in the industries such as papermaking, weaving, belongs to pressure vessel.Its rated operating pressure is 0.3Mpa, and the nominal operation temperature is 143 ℃.Owing to adopt the low-pressure steam heat supply, so can not when work, reach a high temperature, energy-conservation technology and environmental requirement.Also have employing directly electrically heated, this kind heat form power consumption is big; Adopt liquefied gas or combustion of natural gas to heat in addition, this kind heat form cost is high, and temperature distributing disproportionation is even, and production technology is difficult to control.The inventor has invented " normal pressure, high temperature, energy saving baking roller " and had invented " normal pressure, high temperature, energy saving baking roller unit " in 2004 and obtained national patent in 1999; The patent No. is respectively ZL99247978.9, ZL200410010163.4; The similar general drying cylinder of this drying roller tube profile; Its design feature is: have a fixing adjustable deep fat distributor gear in the roller roller is heated, the structure of employing and atmosphere is to keep being in atmospheric pressure state in the roller simultaneously.This drying roller tube can be worked under normal pressure, hot conditions; Drying effect is also better, but because conduction oil contacts with atmosphere under hot conditions, very easily coking is aging; Therefore cause that maintenance load is big, the equipment damage is serious, deficiency such as conduction oil and device systems service life are short.And for example the inventor invented high temperature, efficient, energy-conservation paper-making drying cylinder in 2002; Conduction oil in the patent No. ZL0291804.3, this drying cylinder and air are isolated, have avoided problems such as the conduction oil coking is aging, equipment damage; But because manufacturing cost is high; Difficulty is big, and the dryer surface appearance is inhomogeneous because of the dryer surface heat transfer that many oil pocket dividing plates in the drying cylinder cause when work, and many production technologies cannot be accomplished.
Three, summary of the invention: exist conduction oil to contact with atmosphere under hot conditions that very easily coking is aging, the equipment damage is serious in order to solve " normal pressure, high temperature, energy saving baking roller "; The conduction oil short and unequal problem of surface temperature of drier in service life, the purpose of this invention provides a kind of satisfy big commercial production needs, high efficiency, energy-saving and environmental protection, the high temperature that equipment is not easily damaged, conduction oil reaches the limit in service life, efficient, energy-conservation roller dryer.
Technical scheme of the present invention realizes in the following manner:
One, the energy-efficient roller dryer of this kind high temperature; It is similar cylindrical cylinder of device in drying cylinder; This cylinder forms an interlayer between the drying cylinder inwall, the central tube that a centre blocks (advance, oil return pipe) is equipped with at the roller center, and central tube and the tangent position of drying cylinder spindle nose are fixed on the spindle nose at drying cylinder two ends through flange; The gap of central tube and drying cylinder spindle nose seals with sealing ring, makes the interior cylinder of drying cylinder along with drying cylinder is synchronized with the movement.The central tube two ends link to each other with main oil return pipe with main oil inlet pipe through swivel joint, form the circulatory system of oil circuit.
Two, the cylinder in the drying cylinder is provided with the oil groove that is evenly distributed; The cylinder that is connected with oil groove is made up of the steel plate that has equally distributed oilhole; And oil groove is connected with the center oil inlet pipe through several oil-feed arms again, and conduction oil gets into the oil-feed arm through oil inlet pipe, gets into oil groove again; Oil in the oil groove gets in the interlayer through oilhole uniformly, and the oil after in interlayer, doing manual work flows out drying cylinder through oil returning tube again.
Three, the oil groove that is connected with cylinder in the drying cylinder is the inclination oil duct that is parallel to each other and forms.
Good effect of the present invention is:
1, the conduction oil in this roller dryer interlayer can be laterally, vertically flow freely, realized the uniform and stable property of surface temperature of drier, and avoided the aging damage that causes to system and equipment of conduction oil coking.
2, the bake out temperature of this roller dryer rises to 350 ℃ for 143 ℃ from existing operating temperature, has improved equipment thermal efficiency greatly, has shortened technological process.
3, this roller dryer adopts the conduction oil medium heat supply of working, and the thermal efficiency is high, and do not have waste liquid in the course of work, waste gas is discharged, and helps environmental protection.Also energy-conservation than steam cylinder, electric drying cylinder.
4, the conduction oil in this roller dryer good sealing effect, roller moves under air-proof condition, and conduction oil can not leak outside.
5, this roller dryer can be regulated arbitrarily between normal temperature to 350 ℃.
