The upper roller assembly 120 is arranged above the lower roller assembly 130 with a spacing. The first gap between adjacent rollers in the upper roller assembly 120 is larger than the second gap between adjacent rollers in the lower roller assembly 130. The low end of the upper roller assembly 120 is arranged flush with the low end of the lower roller assembly 130. The sintering trolley 40 is used for material distribution and is arranged directly below the upper roller assembly 120 and the lower roller assembly 130.

The mixed hopper 20 is used to store mixed material and is located at the topmost position to deliver the mixed material downward. The round roller feeding device 30 is used to accept the mixed material in the mixed hopper 20 and feed it to the hierarchical roller formula cloth ware 10 for distribution. Therefore, the round roller feeding device 30 is arranged below the bottom opening of the mixed hopper 20. After the mixed material enters the round roller feeding device 30, it falls into the hierarchical roller formula cloth ware 10 for hierarchical segregation distribution after rotating in the round roller feeding device 30. Finally, the mixed material falls into the sintering trolley 40 to achieve the segregation distribution effect from large to small from top to bottom.

[0036] It is worth noting that the spacing distance between adjacent rollers can be connected by long holes combined with screw rods during installation, so as to facilitate adjustment; when adjusting the gap, the pressure inside the air bellow can be measured to form interlocking, and the pressure value inside the air bellow is used to adjust the gap between the rollers, for example, the initial setting of the gap between the rollers is a small value a (mm), at this time the negative pressure inside the air bellow is P; the gap between the rollers is adjusted to a+1 (mm) with 1 (mm) as the adjustment level, at this time the pressure inside the air bellow is P1; if P1

The support 111 is obliquely arranged, the first end of the support 111 is connected to the fixed support 112, and the second end of the support 111 is connected to the adjusting support 113. The adjusting support 113 has an adjusting screw 1131 that can be vertically adjusted. The second end of the support 111 is hinged to the top end of the adjusting screw 1131.

[0038] It should be noted that the support 111 serves as a support installation platform, while the fixed support 112 and the adjusting support 113 are used to fix the support 111 on the installation rack (not shown in the figure). The fixed support 112 remains fixed, and the adjusting support 113 is vertically adjustable. In this way, the inclination of the support 111 can be adjusted by adjusting one end.

[0039] As a preferred embodiment of the utility model, the upper roller assembly 120 includes a plurality of upper roller units arranged in parallel and spaced along the oblique extension direction of the support 111. Each upper roller unit includes an upper roller 121, a first coupling 122, a first reduction motor 123, and two first bearing seats 124 arranged opposite to each other along the axial direction of the upper roller 121. Two first bearing seats 124 are connected to two supports 111, respectively. The two ends of the upper roller 121 are rotatably connected to the first bearing seats 124. One end of the upper roller 121 protrudes from the first bearing seat 124 and is connected to the driving end of the first reduction motor 123 through the first coupling 122.

[0040] It should be noted that the upper roller assembly 120 is composed of a plurality of upper roller units arranged side by side and spaced apart, and the spacing distance between the adjacent two upper roller units is the first gap, wherein the upper roller 121 in each upper roller unit is connected to the support 111 through the first bearing seat 124, and since the support 111 is inclined, the plurality of upper rollers 121 are also arranged in an inclined manner after installation, and are rotatably arranged, and one end of the upper roller 121 is arranged to extend out of the first bearing seat 124 to be connected to the driving end of the first speed reducer through the first coupling 122, so that the upper roller 121 is driven to rotate by the first speed reducer; the material flow is accelerated to move from top to bottom by the rotation of the upper roller 121, and the large particle material is segregated during the movement, and since the upper roller 121 accelerates the rolling, the large particle material is preferentially dropped onto the sintering trolley 40 to form a large particle large ball material layer and a large particle small ball material layer arranged below the sintering trolley 40, and the small particle material layer is dropped onto the lower roller assembly 130.

[0041] As a preferred embodiment of the utility model, the lower roller assembly 130 includes a plurality of lower roller units arranged side by side and spaced apart along the inclined extension direction of the support 111, each of the lower roller units includes a lower roller 131, a second coupling 132, a second speed reducer 133, and two second bearing seats 134 arranged opposite to each other along the axial direction of the lower roller 131, the two second bearing seats 134 are connected to the two supports 111 respectively, the two ends of the lower roller 131 are rotatably connected to the second bearing seats 134, and one end of the lower roller 131 extends out of the second bearing seat 134 and is connected to the driving end of the second speed reducer 133 through the second coupling 132.

[0042] It is worth noting that, similar to the upper roller assembly 120, the lower roller assembly 130 is also composed of a plurality of lower roller units arranged side by side and spaced apart, and the spacing distance between the adjacent two lower roller units is the second gap, and the lower roller 131 in each lower roller unit is also connected to the support 111 in the form of a bearing seat (second bearing seat 134) and is arranged in an inclined manner along with the inclination of the support 111, and is connected to the driving end of the second speed reducer through the second coupling 132, and the second speed reducer drives the lower roller 131 to rotate; after the small particle material layer is dropped onto the lower roller 131, the medium particles are segregated on the lower roller 131, and since the lower roller 131 accelerates the rolling, the small particle material layer is preferentially dropped into the middle part of the sintering trolley 40, and the small particle material layer is dropped onto the upper part of the sintering trolley 40 through the second gap, so that the material is arranged from bottom to top, and the material particles become smaller and smaller.

[0043] As a preferred embodiment of the utility model, it further comprises two material blocking plates 140 arranged opposite to the axial direction of the upper roller 121, the material blocking plate 140 is connected to the support 111 and arranged on both sides of the upper roller 121 and the lower roller 131.

[0044] It is worth noting that the material blocking plate 140 is used to prevent the mixed material from scattering outside the sintering trolley 40 when being distributed, so it needs to be arranged on both sides of the upper roller 121 and the lower roller 131, so as to achieve a better material blocking effect.

[0045] Further, the vertical spacing distance between the upper roller assembly 120 and the lower roller assembly 130 is 30cm-40cm.

[0046] It should be noted that here refers to the vertical spacing distance between the inclined section composed of the upper rollers 121 in the upper roller assembly 120 and the inclined section composed of the lower rollers 131 in the lower roller assembly 130, which is used as a material falling space, and in a preferred embodiment of the application, it can be set to 30cm-40cm, preferably 30cm, and those skilled in the art can select according to actual needs.

[0047] Further, the number of the upper roller units in the upper roller assembly 120 is nine, and the number of the lower roller units in the lower roller assembly 130 is seven.

[0048] It should be understood that since the upper roller assembly 120 and the lower roller assembly 130 are arranged in parallel and spaced apart, the length of the upper roller assembly 120 needs to be longer than the length of the lower roller assembly 130, so that the low end of the upper roller assembly 120 and the low end of the lower roller assembly 130 are arranged in parallel and spaced apart, thereby avoiding interference when falling material from the low end, affecting the segregation effect, and the more the number of rollers, the higher the rolling efficiency, which can more effectively ensure that large particles are laid on the bottom of the sintering trolley 40 first; therefore, the upper roller assembly 120 adopts a nine-roller structure, and the lower roller assembly 130 adopts a seven-roller structure.

[0049] Further, the gap distance between two adjacent upper rollers 121 is 20mm-25mm, and the gap distance between two adjacent lower rollers 131 is 5mm-7mm.

[0050] It should be noted that the gap distance between the upper rollers 121 (first gap) and the gap distance between the lower rollers 131 (second gap) can be set according to the particle size distribution of the required material, and preferably, the gap distance between two adjacent upper rollers 121 can be set to 20mm, and the gap distance between two adjacent lower rollers 131 can be set to 5mm.

[0051] Further, the side wall of the mixing hopper 20 is inwardly inclined from the top end to the bottom end.

[0052] It should be noted that such a setting can facilitate the downward sliding of the mixed material in the mixing hopper 20 and reduce the material blocking and piling in the mixing hopper 20.

[0053] Further, the inclination angle of the upper roller assembly 120 and the lower roller assembly 130 is 40°-45°.

[0054] It can be understood that the inclination angle can be adjusted by adjusting the support 113, and the setting of the inclination angle is suitable for facilitating the material falling and distribution, and in a preferred embodiment of the present application, the inclination angle of the upper roller assembly 120 and the lower roller assembly 130 can be set to 40°.

[0055] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
