Abstract
Description
Technical Field
[0001] This utility model relates to a sintering cup mixing and discharge anti-caking device, belonging to the field of metallurgical equipment. Background Technology
[0002] Sintering cup experiments are one of the most important methods in the metallurgical industry for studying sintering production processes, and the results have significant guiding value for actual sintering production. During the sintering experiment, the first mixing step in the vertical mixing tank requires mixing various raw materials such as iron concentrate, galvanized iron, coke powder, activated ash, and limestone with water according to a specific ratio, typically for five minutes before discharge. This step affects the subsequent second mixing and granulation, thus significantly impacting the sintering quality and presenting a problem that urgently needs to be addressed.
[0003] Currently, the caking of the mixture is a common problem in the initial mixing and discharge process of sintering cup tests. When the material after the initial mixing directly enters the receiving hopper, due to uneven moisture content and insufficient mixing, some of the mixture will form caking lumps with a diameter greater than 50mm. After these caking lumps enter the secondary mixing drum granulation process, although some of them will break up due to the rotational inertia of the drum, some large caking lumps will still remain, resulting in uneven granulation with an average particle size of 3-5mm and some particles that are larger than 10mm. This affects the air permeability and yield of the sintering quality throughout the entire sintering process. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the agglomeration of the primary mixing material into the secondary mixing material affects the permeability and sintering quality of the entire sintering process, resulting in a low yield.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a sintering cup mixing discharge anti-caking device, including an anti-caking net and a connector. One end of the anti-caking net is hinged to the connector, and the other end is provided with flat support members on both sides that can be placed on the frame of the receiving hopper. The connector can be hung on the side wall of the receiving hopper opposite the flat support members.
[0006] The connecting component in the above-mentioned device has a mesh structure.
[0007] In the aforementioned device, a buckle is provided on the outer side of the connector.
[0008] Furthermore, the aforementioned device has at least two latches that are spaced apart.
[0009] Furthermore, the buckle in the above device has an arc-shaped structure.
[0010] In the aforementioned device, the upper part of the connector is bent outward into an arc structure.
[0011] Furthermore, the device also includes a movable ring, and the hinged ends of the anti-caking mesh and the connector are inserted inside the movable ring, so that the anti-caking mesh and the connector are hinged.
[0012] In the above-mentioned device, the through holes on the anti-caking mesh are long, vertical mesh openings.
[0013] Furthermore, the anti-caking mesh in the above-mentioned device has a wire diameter of 2mm and a vertical mesh opening diameter of 15mm×150mm.
[0014] Furthermore, the anti-caking mesh, connectors, buckles, and movable rings in the above-mentioned device are all made of 304 stainless steel.
[0015] The beneficial effects of this utility model are: the device is directly placed on the upper opening of the receiving hopper through the connecting parts and the flat support parts, which makes the installation convenient. At the same time, the anti-caking mesh screens the mixed discharge, and the device can crush large pieces of material after folding to ensure the particle size of the mixed discharge.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 3As shown, this utility model discloses a sintering cup mixed discharge anti-caking device, comprising an anti-caking mesh 1 and a connector 2. One end of the anti-caking mesh 1 is hinged to the connector 2, and the other end is provided with flat support members 11 on both sides, which can be placed on the side wall of the receiving hopper 5. The connector 2 can be hung on the side wall of the receiving hopper 5 directly opposite the flat support member 11. Those skilled in the art will understand that this device achieves screening and filtration of mixed discharge through the anti-caking mesh 1. In practice, the connector 2 and the flat support member 11 are set at the upper inlet of the receiving hopper 5, allowing the mixed discharge to directly enter the anti-caking mesh 1. Since the entire device is made of the connector 2 and the flat support member 11, the right end of the anti-caking mesh 1 is actually placed in the upper right part of the receiving hopper 5, while the left end is hinged to the connector 2 and located inside the receiving hopper 5, with the connector 2 tightly attached to the inner wall of the receiving hopper 5. This structural arrangement allows the anti-caking mesh 1 to be tilted during actual use, further achieving filtration of the mixed discharge.

[0025] Preferably, the buckle 3 in the above-mentioned device has an arc-shaped structure. Those skilled in the art will understand that the preferred shape of the buckle 3 in this device is actually an arc-shaped structure. Since the buckle 3 is directly attached to the upper end of the receiving hopper 5, the opening of the buckle 3 should face downwards, that is, towards the hinge.
[0026] Preferably, the upper part of the connector 2 in the above-described device is bent outward into an arc shape. Those skilled in the art will understand that, in order to ensure a tight fit between the connector 2 and the inner wall of the receiving hopper 5, the upper part of the connector 2 is preferably bent outward into an arc shape.

Those skilled in the art will understand that the device is further preferably provided with a movable ring 4 to achieve the hinged connection between the anti-caking mesh 1 and the connector 2, reducing manufacturing costs. Since the connector 2 can preferably be a mesh structure, the hinged connection can be achieved simply by inserting the anti-caking mesh 1 and the connector 2 into the movable ring 4. The number of movable rings 4 should be at least two, spaced apart.
[0028] Preferably, the through holes on the anti-caking mesh 1 in the above-mentioned device are elongated vertical mesh openings 12. Those skilled in the art will understand that, in order to better improve the filtration effect of the anti-caking mesh 1, the through holes on the anti-caking mesh 1 are preferably elongated vertical mesh openings 12, that is, the length direction of the vertical mesh opening 12 is perpendicular to the hinge axis direction.
[0029] Preferably, the anti-caking mesh 1 in the above-mentioned device has a wire diameter of 2mm and a mesh size of 15mm×150mm for the vertical mesh opening 12. Those skilled in the art will understand that the anti-caking mesh 1 is further preferably made with a material diameter and a hole size of 2mm, specifically with a vertical mesh opening 12 having a mesh diameter of 15mm×150mm.
[0030] Preferably, the anti-caking mesh 1, connector 2, buckle 3, and movable ring 4 in the above-mentioned device are all made of 304 stainless steel. Those skilled in the art will understand that, in order to ensure that no impurities are mixed into the filter, and to increase structural strength and lifespan, the anti-caking mesh 1, connector 2, buckle 3, and movable ring 4 are preferably made of 304 stainless steel.
