Abstract
The utility model discloses a water cooling chute conveying device for discharging of a rotary hearth furnace. The water cooling chute conveying device comprises a plurality of sectional slide pipes, water cooling sleeves on the external side walls of the slide pipes, and atmosphere control systems arranged at the lower parts of the slide pipes, wherein the sectional slide pipes are connected through flanges; and the slide pipes are inclined and vertically arranged in a staggering mode; and the obliquely arranged slide pipes have inclination angle ranging from 60 to 70 degrees. The water cooling chute conveying device has an ingenious structure, and can be used for conveying high-temperature materials, and can prevent a high-temperature ball body from falling and breaking in the chute and preventing a chute body from being rubbed, as well as improve the high-temperature deformation resistance and high-temperature material oxidizing inhibiting performances of the chute.
Description
Technical field
The utility model relates to a kind of water-cooled chute transport, is specifically related to a kind of water-cooled chute transport of rotary hearth furnace discharging, is applied to the conveying of the spherical material of high temperature from discharging equipment to cooling device that rotary hearth furnace is produced.
Background technology
Chute is two logistics corridors between the equipment.Product behind the rotary hearth furnace reduction is spherical; Have hardness big with characteristics such as the easy oxidation of high temperature; The course of conveying of total high temperature sphere material from discharging equipment to cooling device with this, the problem of chute wearing and tearing, high temperature deformation, buildup and material high-temperature oxydation appears easily.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of breakage of falling that has reduced spheroid, suppresses the water-cooled chute transport of the rotary hearth furnace discharging of high-temperature material oxidation.
Technical scheme: for solving the problems of the technologies described above; The water-cooled chute transport of the rotary hearth furnace discharging of the utility model; Comprise the water collar of plurality of sections elephant trunk, elephant trunk lateral wall and the atmosphere control system of elephant trunk bottom; Connect through connector between each section elephant trunk, and establish three places and support, connector is generally flange; Said elephant trunk by tilt, the mode of vertical interlaced arranges that the inclination angle of the elephant trunk that is in tilted layout is 60 °～70 °, reduce when guaranteeing the smooth landing of material to fall and to the impact wear of chute.
Said elephant trunk materials inside shock point place arranges baffle plate, forms the thin bed of material, further reduces wear.
Every section chute includes the water collar on inner elephant trunk and the elephant trunk outer wall.Rectangular configuration is adopted in said elephant trunk madial wall cross section, and four sidewalls are interlaced to be built, and big groove is welded; Wherein crossing charge level sidewall steel plate thickness is 20mm, and three steel plate thickness are 16mm in addition.
Said water collar is direct-connected water collar, and the water collar on four outer walls of every section elephant trunk is independent separately, satisfies the low in and high out principle, and the water collar inside dividing plate that is crisscross arranged makes water be " S " shape and flows.Guarantee the abundant cooling of inside panel and weld seam thereof fully, satisfied high temperature deformation resistance.
Bottom chute interior nitrogen injection can form nitrogen atmosphere in the chute exit, make the high-temperature oxydation of material be effectively controlled.
Beneficial effect: the water-cooled chute transport of the rotary hearth furnace discharging of the utility model; Structure is ingenious; Can be used to carry high-temperature material, can avoid the high temperature spheroid in chute fall breakage and to the friction of cell body, the anti-deforming that improves chute with suppress function such as high-temperature material oxidation.

Fig. 2 is the left view of the utility model;
Fig. 3 is a water collar internal partition sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Shown in Fig. 1 to 3; The water-cooled chute transport of a kind of rotary hearth furnace discharging of the utility model comprises the water collar of plurality of sections elephant trunk, elephant trunk lateral wall and the atmosphere control system of elephant trunk bottom, and five sections elephant trunks are arranged in the present embodiment; Be respectively first elephant trunk 1, second elephant trunk 2, the 3rd elephant trunk 3, the 4th elephant trunk 4, the 5th elephant trunk 5; Connect through connector 6 between each section elephant trunk, and establish three places and support, connector 6 is generally flange; First elephant trunk 1, second elephant trunk 2, the 3rd elephant trunk 3, the 4th elephant trunk 4 and the 5th elephant trunk 5 successively according to tilt, the mode of vertical interlaced arranges; The inclination angle of the elephant trunk that is in tilted layout is 60 °～70 °, reduces when guaranteeing the smooth landing of material to fall and to the impact wear of chute.
In the present embodiment, every section elephant trunk is to be welded by four block plates, and water collar is on the lateral wall of elephant trunk; Water collar is direct-connected water collar, and the water collar on four outer walls of every section elephant trunk is independent separately, satisfies the low in and high out principle; The water collar inside dividing plate 7 that is crisscross arranged, current get into from water inlet 8, flow out from delivery port 9; Be " S " shape and flow, guarantee the abundant cooling of inside panel and weld seam thereof fully, satisfy high temperature deformation resistance.Elephant trunk materials inside shock point place arranges baffle plate 11, forms the thin bed of material, further reduces wear.Rectangular configuration is adopted in elephant trunk madial wall cross section, and four sidewalls are interlaced to be built, and big groove is welded, and wherein crossing charge level sidewall steel plate thickness is 20mm, and three steel plate thickness are 16mm in addition.
In the utility model, also on the 5th elephant trunk 5, be provided with four air inlets 10, during use inert gas blasted chute interior, form nitrogen atmosphere in the exit, suppress material and again be oxidized.Bottom chute interior nitrogen injection can form nitrogen atmosphere in the chute exit, make the high-temperature oxydation of material be effectively controlled.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
