AI Technical Summary
In cement production, the limited installation position between the raw material roller and the air classifier leads to uneven material feeding, resulting in uneven wear of the steel plate inside the air classifier, reduced wind-driven material propulsion, and low equipment operating efficiency.
Several uniform material plates are set in the front section of the feeding device. The uniform material plates are offset to one side from top to bottom and distributed in a stepped manner. There are gaps between adjacent uniform material plates. A disperser and a dispersing rod are set in the rear section to ensure uniform material distribution.
This achieves uniform distribution of materials at the outlet of the feeding device, reduces steel plate wear, improves the efficiency of wind-driven material handling, and reduces the power consumption of the equipment.

Description
TECHNICAL FIELD
[0001] The utility model relates to cement production's material unloading technical field, concretely relates to a unloading device and raw material roller thereof. BACKGROUND
[0002] In cement production, the raw material is sent into the powder selecting machine after being crushed by roller pressing and through the unloading device, and the subsequent material is realized by the unloading device connected with the powder selecting machine arranged at the outlet of the raw material roller.
[0003] The unloading device currently applied in the factory is divided into front section and rear section, and the front section has a large lateral angle due to the limitation of the installation position between the raw material roller and the powder selecting machine, which causes the material to deviate to one side in the rear section during unloading, and there is obvious uneven unloading. The lower powder selecting machine has a corresponding unloading passage for the rear section of the unloading device, and due to the uneven unloading, the material causes uneven wear of the steel plate in the powder selecting machine. After a period of use, the steel plate on one side needs to be replaced, while the steel plate on the other side has little wear. In addition, the material is transported by wind force in the powder selecting machine. Due to the uneven material unloading to the inlet of the powder selecting machine, the wind-driven material effect is weakened, most of the wind force flows out from the space without material, and the operation efficiency of the equipment cannot be improved.

[0020] The utility model will be explained in detail in combination with the drawings and specific embodiments. In the specification, the size proportion of the drawings does not represent the actual size proportion, and it is only used to reflect the relative position relationship and connection relationship between the components. The components with the same name or the same label represent similar or identical structures, and are limited to the purpose of illustration.
[0021] Figure 1The utility model discloses a structure schematic drawing. The blanking device 1 includes the front section 2 and rear section 3 connected with each other, since blanking device 1 utilizes gravity blanking, its use is at least from top to bottom inclined, therefore has fixed upper and lower. It is connected with the raw material roll equipment of upstream and the powder selecting machine equipment of downstream, for conveying the material of raw material roll crushing to the powder selecting machine. Be subjected to the installation position between raw material roll and powder selecting machine, blanking device 1 cannot directly connect raw material roll and powder selecting machine with the path perpendicular to horizontal plane in the conveying plane defined in its conveying surface, but will be in the conveying plane with horizontal plane into an acute angle, thus will cause blanking material to be deflected to a side under the influence of gravity during blanking, cause material to concentrate on one side of blanking device 1. In order to solve this problem, blanking device 1 is provided with front section 2 at least to make up the lateral difference between raw material roll and powder selecting machine, and the setting path of front section 2 deviates to a side from top to bottom in its conveying plane.
[0022] Figure 2 It is the schematic diagram observed from the normal of the conveying plane of front section 2. In order to realize the guidance to material, a plurality of material uniformizing plates 21 are arranged on the front section 2, and any material uniformizing plate 21 deviates to a side from top to bottom with the front section 2. When the material contacts the material uniformizing plate 21, under the drainage of the material uniformizing plate 21, it is forced to move to a side deviated from blanking device 1, thereby guiding the original material on the non-deviated side below the front section 2 to the deviated side, and realizing the purpose of the relatively uniform distribution of the material at the lower end outlet of the front section 2. In order to improve the effect of dispersion drainage, a plurality of material uniformizing plates 21 are distributed in a stepped manner to the deviated side from top to bottom on the front section 2, and the adjacent material uniformizing plates 21 have gaps in the horizontal direction, so that part of the material of the upper material uniformizing plate 21 directly falls from the gap, and the other part falls on the lower material uniformizing plate 21 to continue to move to the deviated side. Through the successive operation of the multiple layers of material uniformizing plates 21, the substantially uniform distribution of the material in the width direction at the outlet below the front section 2 can be realized.
[0023] The blanking device 1 also includes the rear section 3 connected with the outlet of the front section 2, and the path of the rear section 3 is arranged perpendicular to the horizontal plane in the conveying plane, so the problem of material deviation caused by the arrangement angle does not need to be considered. However, in order to maintain the uniform distribution of the material on the rear section 3, a plurality of dispersers 31 with a plurality of protruding surfaces can be arranged on the conveying surface of the rear section 3 to maintain the dispersion state of the material. The plurality of dispersers 31 are distributed in a pyramid shape on the surface of the rear section 3, with the layer with a smaller number being located on the upper side and the layer with a larger number being located on the lower side, so that the material is again restored to a relatively uniform distribution under the dispersion of the disperser 31 after contacting the disperser 31, avoiding the aggregation problem of the material on the rear section 3. The disperser 31 is preferably arranged at the conveying surface of the end close to the lower side of the rear section 3, so that the material uniformly passes through the disperser 31 and quickly leaves the outlet of the rear section 3.
[0024] The material flows out of the rear section 3 and enters different channels of the powder concentrator. Before the material enters the powder concentrator, the required separating rod 32 can be arranged at the outlet of the rear section 3 to separate the uniform material into corresponding several strands and send them into different channels. The separating rod 32 is arranged at the corresponding position of the outlet of the rear section 3 at the joint of each channel to directly guide the material to different channels of the powder concentrator. The separating rod 32 can be a wedge-shaped protrusion protruding from the surface of the rear section 3 to the inlet of the rear section 3. In actual use, a 70*70mm angle steel is welded on the surface of the rear section 3 instead, and the angle of the angle steel points to the inlet of the rear section 3. After the technical improvement of the roller hopper guide plate, the material distribution at the V-concentrator inlet is improved, the system negative pressure rises by about -400pa, the circulating fan speed is reduced by 150r / min, the power consumption is reduced by about 1.5kwh / t, and obvious reduction is obtained.
[0025] The above merely describes the preferred embodiments of the present application, and does not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
