Description

Technical Field

[0001] This utility model belongs to the field of sintering technology, and in particular relates to an automatic material cleaning device for the feed inlet of a sintering cylindrical mixer. Background Technology

[0002] Cylindrical mixers are widely used in steel enterprises as traditional mixing and granulation equipment. Considering various factors, sintering plants usually adopt a two-stage mixing process, both of which use cylindrical mixers. The purpose of the first mixing is to achieve uniform mixing, while the main function of the second mixing is granulation.

[0003] The cylindrical mixer uses the rotation of the cylinder to make the material move in a spiral motion inside the cylinder. During the movement, the material repeatedly rolls, scatters, and moves forward, thereby completing the mixing and granulation process. At the feed inlet of the cylindrical mixer, the material is transported from the belt conveyor. Because the cylinder is in a rotating state, some of the material that just falls into the cylinder will be scattered outside the cylinder due to the force. This often requires the workers to clean it up in time to prevent the material from accumulating and affecting the normal operation of the equipment and damaging the clean production environment. However, the cumulative spillage over time leads to a high labor intensity for the workers. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic material cleaning device for the feed inlet of a sintering cylindrical mixer. By arranging a collection hopper below the feed inlet of the cylindrical mixer, it can actively collect scattered materials. The scattered materials can be recycled back to the feeding conveyor belt at the feed inlet of the cylindrical mixer by a circulating tube chain conveyor, realizing automated slag removal and recycling, reducing the labor intensity of workers, and preventing slag from affecting the normal operation of the equipment. At the same time, through the design of a spare conveyor belt, when the circulating tube chain conveyor is damaged or under maintenance, the materials in the collection hopper can be removed and recycled by a loading vehicle, reducing labor intensity and improving cleaning efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an automatic material cleaning device for the feed inlet of a sintering cylindrical mixer, including a cylindrical mixer and a material cleaning device body.

The top and bottom of the falling section are connected to the upper recovery section and the lower recovery section respectively through a second turning box of 90 degrees. A third turning box of 180 degrees is provided between the ends of the receiving section and the lower recovery section away from the lifting section. A fourth turning box of 180 degrees is provided between the ends of the dropping section and the upper recovery section away from the lifting section.

[0006] Furthermore, it also includes a first-level platform and a second-level platform. The cylindrical mixer is installed on the second-level platform, the collection hopper is installed on the first-level platform via a first bracket, and the spare conveyor belt is installed on the first-level platform.

[0007] Furthermore, the receiving section and the lower recovery section are installed on the first-floor platform, and the lifting section and the falling section are provided with a reinforcing frame between the first-floor platform and the second-floor platform. The fourth steering box is fixed to the second-floor platform by a second bracket.

[0008] Furthermore, a feeding conveyor belt is provided outside the feed inlet of the cylindrical mixer, the feeding conveyor belt is installed on the second-level platform, and the return pipe is located directly above the feeding conveyor belt.

[0009] Furthermore, the second-level platform is provided with a clearance opening that mates with the top of the collection hopper, and the feeding conveyor belt and the second support both span the clearance opening.

[0010] Furthermore, the bottom of the collecting hopper is provided with a square joint, and the top of the main discharge pipe is connected to the bottom of the square joint through a flange.

[0011] This utility model has the following beneficial effects: This invention features a collection hopper positioned below the feed inlet of a cylindrical mixer, which actively collects scattered materials. A circulating conveyor belt then recycles the scattered materials back to the feed conveyor belt at the feed inlet of the cylindrical mixer, achieving automated slag removal and recycling. This reduces the labor intensity of workers and prevents slag from affecting the normal operation of the equipment. Furthermore, the design of a spare conveyor belt allows materials in the collection hopper to be removed and recycled by a loading vehicle during periods of damage or maintenance of the circulating conveyor belt, further reducing labor intensity and improving cleaning efficiency.
