Abstract
The utility model relates to a rigid tee-joint sleeve structure which mainly comprises a first outer steel tube (1) and a first inner sleeved steel tube (2), wherein the first inner sleeved steel tube (2) is located in the middle of the first outer steel tube (1), a large hole (5) and a small hole (6) are respectively formed at the same parts in the middles of the first outer steel tube (1) and the first inner sleeved steel tube (2), the large hole (5) is welded on the outer wall of an inner steel tube after being forged, the small hole (6) is welded with a tube opening of a second inner sleeved steel tube (7) of a second outer steel tube (8) to form a tee-joint sleeve pipeline with the original sleeve. The rigid tee-joint sleeve structure is simple in structure and good in practicality, effectively solves the problem in a tee-joint pipeline that asphalt or modified asphalt is easily cured and blocked in the pipeline, and guarantees the normal operation of asphalt or modified asphalt processing equipment.
Description
Technical field
The utility model belongs to the syndeton of pitch or modified asphalt device or pipeline, is specifically related to a kind of rigidity tee-joint sleeve structure.
Background technology
Continuous increase along with China's asphalt concrete pavement, the consumption of pitch or modified bitumen, rubber asphalt also is on the increase, the equipment of relevant pitch or modified bitumen processing has also obtained fast development, also functional performance and the reliability of pitch Production and application modified asphalt device has also been proposed requirements at the higher level.As everyone knows, be solid-state under pitch or the modified bitumen normal temperature, in the conveying bitumen process, must just can carry and process its liquefaction of heating.Finish by bilayer sleeve on the straight tube road of general asphalt delivery, but triplate line and elbow are difficult to add heating arrangement because of complex structure, and the result causes the pitch at threeway or elbow pipeline place to be difficult to liquefaction and causes pipeline blockage.Traditionally, although also available open firing makes its liquefaction, easily cause environment pollution, also have potential safety hazard.
Summary of the invention
The utility model mainly solves in pitch or the modified bitumen triplate line, and pitch or modified bitumen solidify the problem of stopping up, and guarantees pitch or the normal conveying of modified bitumen in pipeline.
The technical solution of the utility model: the utility model relates to a kind of rigidity tee-joint sleeve structure, mainly formed by the first outer steel pipe 1 and the first inner sleeve steel pipe 2, the first inner sleeve steel pipe 2 is positioned at the first outer steel pipe 1 middle part, same place is opened respectively a macropore 5 and aperture 6 in the middle of the first outer steel pipe 1 and the first inner sleeve steel pipe 2, after forging, macropore 5 is welded in interior outer wall of steel pipe, the second inner sleeve steel pipe 7 mouths of pipe welding of aperture 6 and the second outer steel pipe 8, become the tee-joint sleeve pipeline with former sleeve-shaped, the 3rd inner sleeve steel pipe 4 li circulations pitch or modified bitumen, sleeve pipe annular gap 3 li circulations conduction oil or other medium, the 3rd inner sleeve steel pipe 4 and sleeve pipe annular gap 3 are separate space, and first mouth of pipe 9 and second mouth of pipe 10 are respectively the import and export of conduction oil or other medium.
The utility model compared with prior art has following beneficial effect: the utility model is simple in structure, by the heating of conduction oil to triplate line place pitch, solves or has accelerated the bitumen pipeline blockage problem that asphalt solidification causes.

The specific embodiment
The utility model relates to a kind of rigidity tee-joint sleeve structure, mainly formed by the first outer steel pipe 1 and the first inner sleeve steel pipe 2, the first inner sleeve steel pipe 2 is positioned at the first outer steel pipe 1 middle part, same place is opened respectively a macropore 5 and aperture 6 in the middle of the first outer steel pipe 1 and the first inner sleeve steel pipe 2, after forging, macropore 5 is welded in interior outer wall of steel pipe, the second inner sleeve steel pipe 7 mouths of pipe welding of aperture 6 and the second outer steel pipe 8, become the tee-joint sleeve pipeline with former sleeve-shaped, the 3rd inner sleeve steel pipe 4 li circulations pitch or modified bitumen, sleeve pipe annular gap 3 li circulations conduction oil or other medium, the 3rd inner sleeve steel pipe 4 and sleeve pipe annular gap 3 are separate space, and first mouth of pipe 9 and second mouth of pipe 10 are respectively the import and export of conduction oil or other medium.
The utility model is mainly used in pitch or the equipment for processing modified asphaltum, 3 li circulations of sleeve pipe annular gap conduction oil, the 3rd inner sleeve steel pipe 4 li circulations pitch or modified bitumen.When needing conveying bitumen, the conduction oil of 3 li storages of first circulating sleeve pipe annular gap, make its pitch or modified bitumen liquefaction with 4 li storages of the 3rd inner sleeve steel pipe after, open again bitumenpump, the beginning conveying bitumen has guaranteed that bitumen pipeline is smooth and easy without stopping up.
The utility model also is used for other pipeline equipment, 3 li circulations of sleeve pipe annular gap heating liquid, 4 li circulations of the 3rd inner sleeve steel pipe heating object.When heating object need liquefy, the heating liquid of 3 li storages of first circulating sleeve pipe annular gap with heating object liquefaction, had guaranteed the smooth and easy of heating object pipeline.
