Description

Be used for the structure of controlling temperature that two of double screw extruder screw rod advances scene 2
Technical field
The utility model relates to a kind of structure of controlling temperature of double screw extruder screw rod, particularly a kind ofly is used for the structure of controlling temperature that two of double screw extruder screw rod advances scene 2.
Background technology
The common outer circulation mode that adopts of the temperature of double screw extruder screw rod control is now promptly circulated by the logical oil of the screw rod inner core of loop in work by external fuel tank, with the temperature of control screw rod.If because of shear heat makes the temperature of screw rod discharge end be higher than design temperature, then Xun Huan medium is taken away unnecessary heat, be lower than design temperature as the temperature of screw rod discharge end, then medium is brought up to design temperature with the temperature of screw rod.Use the heat loss of control temperature mode of this one-in-and-one-out bigger, during in particular for the flat twin-screw of major diameter, big L/D ratio, its temperature control poor effect, precision are not high yet.
Summary of the invention
The purpose of this utility model is that the temperature that solves double screw extruder screw rod in the prior art is controlled the existing above-mentioned problem of control temperature mode of utilizing one-in-and-one-out, and a kind of structure of controlling temperature that two of double screw extruder screw rod advances scene 2 that is used for is provided.The utility model is designed for the structure of controlling temperature that two of double screw extruder screw rod advances scene 2, comprises the screw rod of hollow, it is characterized in that: first half and latter half of one group of oil circuit access way arranged respectively in the screw rod of hollow.Described two groups of oil circuit access ways are made up of following structures: interior siphunculus is arranged in the screw rod of hollow, the top of interior siphunculus is positioned at the screw rod top of hollow, internal channel is positioned on the screw rod axis of hollow, gapped between the screw rod of interior siphunculus and hollow, in outside interior siphunculus, being with, outer two sleeve pipes, at interior siphunculus, in, all gapped between the screw rod of outer two sleeve pipes and hollow, in, the top of outer two sleeve pipes is positioned at the middle part of the screw rod of hollow, there is a big envelope at middle part at the screw rod of hollow, the screw rod inwall of airtight outer tube of big envelope and hollow and the gap between middle sleeve and the outer tube, on the tube wall at the nearly big envelope of outer tube place, have through hole, gap between the screw rod inwall of through hole connection outer tube and hollow and the gap between outer tube and the middle sleeve, there is separator at screw rod rear portion in hollow, four sealing surfaces are arranged with interior siphunculus end and interior siphunculus and middle sleeve on the separator, middle sleeve and outer tube, each is self-enclosed in gap between the screw rod of outer tube and hollow, four through holes are arranged, siphunculus passage and interior siphunculus and middle sleeve in four through holes connect respectively on the screw rod of hollow, middle sleeve and outer tube, the formed passage in gap between the screw rod of outer tube and hollow.The adjusting that the utility model has the advantages that the double screw extruder extruder temperature is divided into two zones, is convenient to accurately control temperature.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise the screw rod 1 of hollow among the figure, it is characterized in that: first half and latter half of one group of oil circuit access way 2,3 arranged respectively in the screw rod 1 of hollow.Described two groups of oil circuit access ways 2,3 are made up of following structures: siphunculus 4 in having in the screw rod 1 of hollow, the top of interior siphunculus 4 is positioned at screw rod 1 top of hollow, internal channel 4 is positioned on screw rod 1 axis of hollow, gapped between the screw rod 1 of interior siphunculus 4 and hollow, in outside interior siphunculus 4, being with, outer two sleeve pipes 5,6, at interior siphunculus 4, in, outer two sleeve pipes 5,6 and the screw rod 1 of hollow between all gapped, in, outer two sleeve pipes 5,6 top is positioned at the middle part of the screw rod 1 of hollow, there is a big envelope 7 at middle part at the screw rod 1 of hollow, screw rod 1 inwall of big envelope 7 airtight outer tubes 6 and hollow and the gap between middle sleeve 5 and the outer tube 6, on the tube wall at outer tube 6 nearly big envelopes 7 places, have through hole 8, gap between screw rod 1 inwall of through hole 8 connection outer tubes 6 and hollow and the gap between outer tube 6 and the middle sleeve 5, there is separator 9 at screw rod 1 rear portion in hollow, four sealing surfaces 10 are arranged with interior siphunculus 4 terminal and interior siphunculus 4 and middle sleeve 5 on the separator 9, middle sleeve 5 and outer tube 6, each is self-enclosed in gap between the screw rod 1 of outer tube 6 and hollow, on the screw rod 1 of hollow, there are 11, four through holes 11 of four through holes to connect interior siphunculus 4 passages and interior siphunculus 4 and middle sleeve 5 respectively, middle sleeve 5 and outer tube 6, the formed passage in gap between the screw rod 1 of outer tube 6 and hollow.Gap between screw rod 1 first half of wherein interior siphunculus 4 and interior siphunculus 4 and hollow constitutes the passage 2 of one-in-and-one-out, the passage 3 of the gap formation one-in-and-one-out between the screw rod of interior siphunculus 4 and middle sleeve 5 and outer tube 6 and hollow 1 is latter half of.Carry out temperature control owing to the screw rod 1 with hollow is divided into two ones of front and back, be convenient to accurately control temperature.
