Utility model content
Technical problem to be solved in the utility model provides a kind of double-jacket tube for above drawback, can effectively avoid double-jacket tube bottoms material to deposit, and improves conveying efficiency, improve result of use.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of double-jacket tube, comprises outer tube and interior pipe, wherein, described outer tube and all rounded structure of interior pipe, described outer tube top is provided with multiple access hole, and described access hole linearly distributes, described interior pipe is positioned at described outer tube top, and described interior pipe is welded on described outer tube wall by access hole, described double-jacket tube one end is entrance point, and one end is exit end, and described two ends are equipped with set collar, and described set collar is fastened on described outside pipe, described double-jacket tube outer tip end is provided with air inlet pipe, described air inlet pipe runs through outer tube wall, internal tube is connected to bottom described air inlet pipe, described interior pipe one end is provided with end socket, described end socket is near entrance point, described end socket cross section is trapezium structure, with double-jacket tube cross section for reference plane, described end socket cross section hypotenuse and outer tube central axis are angle A is 45 degree, multiple opening is provided with bottom described interior pipe, described opening section structure triangular in shape, described opening is provided with aeroscopic plate, described aeroscopic plate is inclined to set, described aeroscopic plate becomes leaning angle B to be 10 degree with described vertical direction.
Above-mentioned a kind of double-jacket tube, wherein, described access hole quantity is at least 5.
Above-mentioned a kind of double-jacket tube, wherein, described open amount is at least 7.
Compared with prior art, the beneficial effects of the utility model are:
1, Nei Guan top UNICOM double-jacket tube is outside, and the air inlet structure that its top is arranged especially, realizes the efficient transport of material, be conducive to enhancing productivity by ventilation inlet air intake.
2, the entrance point of double-jacket tube and exit end two ends are equipped with set collar, and described set collar is fastened on outside pipe, can realize effectively clamping, accomplish that easy-to-install ensures its reliability simultaneously to body.
3, there is specially designed efficient end socket interior pipe one end, the trapezium structure of its uniqueness, effectively can ensure the validity of its shutoff; And through the measuring and calculating of up to ten thousand science, with double-jacket tube cross section for reference plane, end socket cross section hypotenuse and outer tube central axis are angle A when being 45 degree, plugging effect the best.
4, multiple opening design bottom interior pipe, can effectively make the air-flow in interior pipe dredge to outer tube, accelerates material in outer tube and transports; And unique design has aeroscopic plate in opening, the aeroscopic plate be obliquely installed plays directional tagging to air-flow, and the air-flow in interior pipe is blowed outer tube bottoms material, and the situation that material deposits occurs to avoid outer pipe bottom to occur.
5, through up to ten thousand science measuring and calculating, when aeroscopic plate becomes leaning angle B to be 10 degree with described vertical direction, while outer pipe bottom not easily deposits material, air-flow transports the most effective of material; If aeroscopic plate becomes leaning angle B to be less than 10 degree with described vertical direction, air flow line is downward, although can purge bottoms material deposition, not easily transports material; If when aeroscopic plate becomes leaning angle B to be greater than 10 degree with described vertical direction, air-flow too tilts, be not easy to the purging to bottom deposit.
