Abstract

本发明涉及塑料制品，废塑造粒，尤其涉及导热油内外加热塑料挤出机，其特征有。(1)解决传统设备带水分高温生产，单面加热，塑料熔焦，碳化，排放有害气体和塑料高温碳化热劣，提高产品质量。(2)采用导热油作为导热体，热能不限制于用电，可采用家用的煤饼，沼气，天然汽，电，废木头等。(3)由于全方位加热，温度只需要调至塑料的熔解点即可，全方位加热使塑料快速地形成熔体，保证了塑料原有的特性，提高塑料再次循环利用品质，减少磨擦阻力，降低电机能耗。

Description

导热油内外加热塑料挤出机
技术领域：
本发明主要针对塑料制品，尤其涉及造纸厂废塑料的带水分生产，效果明显。
技术背景：
废塑造粒挤出机是由电机，变速箱，螺杆和料筒组成的，料筒上方设有投料口，料筒外径由电热环作为热源，热能由料筒外壁向料筒内壁传递，电机作为动能，电机连动变速箱，变速箱连动螺杆旋转，将投料口的原料不断推进挤压，紧贴料筒内壁的原料，在高温的作用下开始由外向里熔化，在螺杆不断旋转挤压的作用下，均匀向出料口挤出，完成一个造粒环节。
这种挤出机设备，由于是单面受热，受热面的原料已是焦点甚至碳化，里面的原料还未熟，严重影响到产品的质量，同时给旋转的螺杆带来非常大的阻力，所以电机也要很大。
发明实施方案：
为了解决现在技术上的技术问题，本发明提供一种高效节能，结构筒单，使用方便的设备。
附图说明：
图1为本发明的结构示意图。
图2为图1图中20的侧向解剖图。
一、导热油循环：电机(1)作为动力源带动(2)高温油泵，将加热熔器的导热油(12)抽出，引入进油管道(3)，导热油由进油管道进入旋转接头静盘的进油口(4)，静盘进油口连接一条静盘进油管作定向油管(28)，由定向油管将导热油连续输送，导热油由螺杆另一端部(5)进入空心螺旋叶片，导热油通过螺旋叶片把热能传递给叶片，从另一个端口流出(6)，通过(6)的导热油进入旋转接头的动盘，导热油进入旋转接头动盘流到旋转接关静盘，由旋转接头静盘的出油口(7)进入螺杆回油管(8)，回油管的导热油进入料筒的进油口(9)，导热油在料筒自然流动，从料筒另一个端口(10) 溢流，通过料筒出油管道(11)流出进入加热熔器(12)，完成一次单循环。
二、设备，(1)所述的螺旋叶片总成(19)是由螺杆(29)和叶片 (27)焊结构加工组成的，螺旋杆和叶片均为空心，螺旋杆和螺旋叶片都设有进油口(5)和出油口(6)，螺旋叶片的进油口和出油口分别和螺杆的进油口和出油口对应焊接，经车床加工得成品，称螺旋叶片总成。
(2)所述料筒(22)由大小二根钢管对应焊接，中间设为空心，料筒上方设有投料口(24)，料筒两端设有进油口(9)和出油口(10)，料筒两端面都设有焊接相连的发兰盘(18)和(20)，用于和轴承固定盘相连接。
(3)传动，电机(13)带动变速箱(14)，变速箱和主动链轮连接(15)，主动链轮由链条(16)牵引连接被动链轮(17)，被动链轮和螺旋杆总成相连接。
三、本发明居于了传统工艺设备的弱点，加以创新，使热能充分利用，全方位受热，提高产品质量，降低成本。
四、以上所迷是本发明的较佳实施案例，并不用于限制本发明，凡在本发明的精神和原则之内所作的任何修改和等同替换，改进等，均包括在本发明范围之内。
