Цель изобретени -- повьппение качества изделий за счет предотвращени иовреждени их во врем термической обработки .The purpose of the invention is to improve the quality of the products by preventing them from being damaged during the heat treatment.
На фиг, 1 изображено предлагаемое устройство; на фиг. 2 сечение А - А на фиг. 1.Fig, 1 shows the proposed device; in fig. 2 section A - A in FIG. one.
Устройство д.т термической обработки длинномерных полимерных изделий содержит корпус 1, заполн емый рабочей средой 2, и установ.ченный в корпусе на горизонтальной оси 3 с возможностью врангени барабан 4.The device dt heat treatment of long polymer products includes a housing 1, filled with working medium 2, and a drum 4 installed in the housing on a horizontal axis 3 with the possibility of vrangeny.
Барабан 4 вынолнеп со сквозными радиальными каналами 5 в боковой стенке и снабжен средством дл подачи рабочей среды под давление.м в его полость. Средство дл подачи рабочей среды под давле- ние.м выполнено в виде насоса 6, всасывающий патрубок 7 которого св зан с нолос- тью корнуса 1, а нагнетательный 8 - с полостью барабана через трубопровод 9, Корпус 1 имеет питаюпдий 10 и сливной 11 иатрубки.The drum 4 is made with through radial channels 5 in the side wall and is equipped with a means for supplying the working medium under pressure m to its cavity. The medium for supplying the working medium under pressure. Is made in the form of a pump 6, the suction inlet 7 of which is connected to the nostrum of the cornea 1, and the discharge 8 to the drum cavity through the conduit 9, the housing 1 has a supply 10 and a drain 11 .
Описание работы устройства дано приме- ните;1ьно к использованию его дл охлаждени .The description of the operation of the device is given; 1no apply to using it for cooling.
Устройство работает следующим образом.The device works as follows.
Выход и;ее из экструдера 12 длинномерное полимерное изделие 13 предварительно охлаждаетс в ванне 14, а затем спирально наматываетс виток к витку на барабан 4 и подаетс в приспособление дл отбора (не ноказано). Корпус 1 через патрубок 10 заполн етс рабочей средой 2 - водой - до уровн заливки всасьпзающего патрубка 7 насоса 6. Затем запускаетс насос 6. При этом вода под давлегщем из нагнетательного патрубка 8 насоса через трубопровод 9 и ось 3 поступает в полость барабана 4, из которой выходит через каналы 5 с образованием подпора вод ной нодуп ки между боковой поверхностью барабана 4 и витками издели 13. Вод на подушка снижает давление издели на поверхность бара0The exit and; from the extruder 12, the lengthy polymer product 13 is pre-cooled in the bath 14, and then the coil is spirally wound up to the coil on the drum 4 and fed to a selection device (not shown). The housing 1 through the nozzle 10 is filled with working medium 2 - with water to the level of filling of the suction nozzle 7 of the pump 6. Then the pump 6 is started. At the same time, the water under pressure from the pump discharge nozzle 8 through the pipe 9 and the axis 3 flows into which comes out through channels 5 with the formation of a water intake pressure between the side surface of the drum 4 and the turns of the product 13. Water on the pad reduces the pressure of the product on the surface of the bar0

оана пропорционально площади подпора и давлению воды, а следовательно, предотвращает сжимание издели во вре.м термической обработки.It is proportional to the backpressure area and the pressure of water, and therefore, prevents the product from compressing during heat treatment.
С увеличение.м диаметра поперечного сечени издели этот положительный эффект увеличиваетс . Давление воды подпора не имеет пр мой зависимости от усили нат жени издели между барабаном и ири- снособление.м дл отбора, так как каждый виток издели испытывает усилие трени на барабане и поэтому не в полной мере передает усилие иат жени на последующие витки. В результате этого примерно к 4-5 витку издели иа барабане, счита со стороны приспособлени дл отбора, усилие нат жени и пропорциональна ему сила прижати витков к барабану снижаетс на 40-50%.With an increase in the cross-sectional diameter of the product, this positive effect is increased. The water pressure of the backwater does not directly depend on the tension of the product between the drum and the irradiation device for sampling, since each turn of the product experiences a force of friction on the drum and therefore does not fully convey the force of the next stage. As a result, by approximately 4–5 turns of the product and the drum, considering from the side of the selection device, the tension and proportional to the force of pressing the turns to the drum decrease by 40–50%.
Таки.м образом, естественное снижение уде.;1ьного давлени на наиболее подверженном с.минанию участке издели и подпор рабочей среды под давлением позвол ют обеспечить высокое качество изделий. При вращении барабана 4 изделие непрерывно перемещаетс по нему и охлаждаетс водой, заполн ющей корпус. Обработанный участок издели сходит с барабана и поступает в приспособление дл отбора.In this way, a natural decrease in the yield. 1 of the pressure at the most susceptible area of the product and the pressure of the working medium under pressure ensure the high quality of the products. When the drum 4 is rotated, the product is continuously moved along it and is cooled by the water filling the body. The treated area of the product comes off the drum and enters the selection device.
