Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and in particular relates to a belt-centered material receiving device. Background Art

[0002] As we all know, in the process of steel metallurgy, slag magnetic separation is a method of treating slag, which is mainly carried out by utilizing the characteristics of magnetic substances in slag for sorting. Slag is a solid waste generated in the steelmaking process, which contains a variety of elements such as iron, calcium, and magnesium, and has a certain recycling value. The material transportation in the slag magnetic separation process mainly relies on belt transportation. In the process of transporting slag, the slag has a high calcium oxide content, the material has a certain humidity, and severe adhesion; it is very important to ensure that the slag falls from the feeding belt to the middle of the receiving belt. The deviation of the slag position from the center of the belt will not only cause the belt to deviate or even wear, but also affect the recycling rate of the slag and pollute the environment.

[0003] At present, in the traditional steel slag magnetic separation process, the initial material particle diameter is 0mm-300mm. After screening through 150m*150mm and 10mm*10mm belt feeding screens, large-particle materials of 10mm-150mm are obtained. The large-particle materials are transported to the processing procedure by belts. During the belt transportation process, the height difference between the feeding belt and the receiving belt is generally greater than two meters, and the material falls directly from the feeding belt through the cylindrical receiving hopper onto the upper surface of the receiving belt.

[0004] However, it was found during the use that the traditional technology still has the following defects:

[0005] 1. When large-particle materials (10mm-150mm) fall, they have a serious impact on the receiving hopper, causing the hopper to wear quickly and generate loud noise.

[0006] 2. Most of the materials fall directly onto the upper surface of the receiving belt, and the materials collide with the receiving belt, causing a large impact. The materials are difficult to keep in the center, causing the receiving belt to deviate and cause safety accidents.

[0007] 3. The receiving hopper has no interception effect on large materials. Large materials that have not been screened out fall directly onto the surface of the receiving belt and may scratch the belt.

[0008] The prior art discloses a dustproof material feeding and discharging device, publication number CN 215029883 U: The prior art staggeredly arranges horizontal baffle plates, and the distance between two adjacent baffle plates in the horizontal direction may be no less than 1.5 times the maximum size of the material, which is used to buffer the falling speed of the material, thereby reducing the impact force of the material; and, in the working process, firstly, crushed rubber particles are freely accumulated on the baffle plate to form a cushioning layer, and the cushioning layer has an inclination angle for guiding the material, so that it can not only guide the material to move downward, but also play a role in buffering the impact force of the material on the baffle plate.

[0009] However, in the above-mentioned prior art, the horizontal distance between two adjacent baffle plates may be no less than 1.5 times the maximum size of the material, resulting in the formation of a vertical channel without a baffle plate buffer inside the device. The material can fall vertically from this channel to the surface of the receiving device, resulting in a high-impact collision phenomenon. It can be seen that the prior art cannot effectively buffer the impact force of the material.

[0010] To this end, the present invention provides a belt-centered material receiving device that can effectively buffer the impact force of materials, reduce noise, and intercept large materials. Utility Model Content

[0022] Preferably, a plurality of left wall buffer plates are parallel to each other, and a plurality of right wall buffer plates are parallel to each other; and the distance between the unloading end of each buffer plate and the fixed wall of the buffer plate is 0.6d.

[0029] 3. The utility model sets the minimum distance between the left wall buffer plate and the right wall buffer plate to 250mm, and the distance between the unloading end of each buffer plate and the fixed wall of the buffer plate is greater than 0.5d, which can effectively intercept unscreened large steel columns and prevent the large steel columns from scratching the receiving belt and causing belt damage; the buffer plates staggered on the left and right make the material running trajectory in the receiving hopper S-shaped, and the large steel columns will be squeezed by the buffer plates on this path.

[0050] Working principle:
