Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying equipment technology, and in particular to a dry-wet material separation device for slag vertical mill inlet. Background Technology
[0002] Slag is a residue left after ore refining. In order to ensure the utilization rate of mineral resources, slag needs to be crushed, ground and refined. The grinding operation requires the use of a mill to grind the slag.
[0003] After iron removal, the return fine powder from the mill enters the hopper. It is then conveyed by belt to the slag conveyor belt. The return fine powder and wet slag enter the mill together. Because the dry fine powder and wet material are mixed in the mill and the high temperature inside the mill, the rotary discharge valve and discharge chute are easily clogged and blocked, affecting the normal operation of the mill. In addition, the belt conveyor generates a lot of dust, which pollutes the environment. Therefore, this application provides a dry and wet material separation device for slag vertical mill to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dry and wet material separation device for slag vertical mill to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A dry-wet material separation device for a slag vertical mill includes: a vertical mill, a discharge pipe extending through the outer wall of the vertical mill, a first return conveyor belt located below the end of the discharge pipe, a return bucket elevator located on the left side of the first return conveyor belt, a return hopper located directly below the discharge port of the return bucket elevator, a fixing frame placed between the vertical mill and the return bucket elevator, a second return conveyor belt connected to the discharge port of the return hopper, mounting holes opened in the outer wall of the vertical mill, a guide hopper extending through the outer wall of the vertical mill, an inlet conveyor belt located above the guide hopper, and a guide pipe extending through the outer wall of the return hopper.
[0007] The outer wall of the second return belt overlaps with the inner wall of the mounting hole, and the vertical mill is connected to the interior of the return bin through the second return belt and the guide pipe.
[0008] The interior of the vertical mill is connected to the first return conveyor belt via a discharge pipe, and the first return conveyor belt is connected to the interior of the return hopper via a return hopper.
[0009] The feed belt is connected to the interior of the vertical mill via a feed hopper. The inner wall of the vertical mill is filled with return fine powder and wet slag.
[0010] The feed tube has a diameter of 300mm and is embedded with a wear-resistant ceramic steel pipe, and the inclination angle between the feed tube and the vertical mill is greater than 80°.
[0011] The top of the mill feed belt is filled with wet slag, and the inside of the return hopper is filled with return fine powder.
[0012] Compared with the prior art, this utility model has at least the following beneficial effects:
[0013] 1. In the above scheme, the structure of the vertical mill, the first return belt, the second return belt, the return hopper, the guide pipe, and the discharge pipe allows the user to transport the return fine powder through the guide pipe during operation, while the wet slag is directly transported through the second return belt and the mill inlet belt. This achieves the effect of separating and transporting dry and wet materials, avoiding the situation where dry return fine powder mixes with wet slag and causes agglomeration, which leads to pipe blockage. This improves the operating efficiency and material transport effect of the device. Furthermore, the return fine powder will not be blown away during operation, thus avoiding dust generation and improving the safety and practicality of the device.
[0014] 2. The above solution has a simple overall structure and can be manufactured by simply adding a guide tube to the original components, which makes it easy for users to manufacture.

Detailed Implementation
[0023] The dry and wet material separation device for slag vertical mill provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0024] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0025] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a dry-wet material separation device for a vertical mill slag feed, comprising: a vertical mill 1, a discharge pipe 8 penetrating the outer wall of the vertical mill 1, a first return belt 2 located below the end of the discharge pipe 8, a return bucket elevator 3 located to the left of the first return belt 2, a return bin 4 located directly below the discharge port of the return bucket elevator 3, a fixing frame 7 placed between the vertical mill 1 and the return bucket elevator 3, a second return belt 5 connected to the discharge port of the return bin 4, an installation hole 11 opened on the outer wall of the vertical mill 1, a guide hopper 10 penetrating the outer wall of the vertical mill 1, an feed belt 6 located above the guide hopper 10, and a guide pipe 9 penetrating the outer wall of the return bin 4. The vertical mill 1, the first return belt 2, the return bucket elevator 3, the return bin 4, the second return belt 5, and the feed belt 6 are connected to the feed belt 4. The structure allows the user to transport wet slag separately via the second return belt 5 and the feed belt 6 during operation. The wet slag is then returned and transported to the fine powder via the guide pipe 9. This achieves the effect of sequential transport of dry and wet materials, preventing the mixing of dry and wet materials into the mill and avoiding blockages in the rotary discharge valve and discharge chute caused by high temperatures inside the mill, which would affect the normal operation of the mill. This effectively solves the problem of easy blockage, extends the cleaning cycle of the discharge chute, and improves the user's production efficiency. Furthermore, the fine powder is directly guided through the guide pipe 9 during transport, preventing it from floating and polluting the surrounding environment, reducing the risk of employee injury, and thus improving the safety of the device during operation.
[0026] like Figure 1 and Figure 3 As shown, the outer wall of the second return belt 5 overlaps with the inner wall of the mounting hole 11, and the vertical mill 1 is connected to the interior of the return bin 4 through the second return belt 5 and the guide pipe 9. Through the structure of the second return belt 5, the wet slag is transported during operation, thereby avoiding the impact on the user's operating efficiency caused by the single-pass transport of wet slag by the mill belt 6, and further improving the practicality of the device.
[0027] like Figure 2 and Figure 4 As shown, the interior of the vertical mill 1 is connected to the first return belt 2 via the discharge pipe 8. The first return belt 2 is connected to the interior of the return bin 4 via the return bucket elevator 3. Through the structure of the first return belt 2 and the return bin 4, the device uses the first return belt 2 to transport wet slag during operation, so that the wet slag can enter the return bin 4 and be transported by the second return belt 5, thereby improving the automation of the device.
[0028] like Figure 1 and Figure 2As shown, the feed belt 6 is connected to the interior of the vertical mill 1 through the feed hopper 10. The inner wall of the vertical mill 1 is filled with return fine powder and wet slag. Through the structure of the vertical mill 1 and the feed belt 6, after the wet slag is transported by the feed belt 6, the wet slag can enter the vertical mill 1 and come into contact with the return fine powder, so that the mill can perform grinding operation on the wet slag, thereby achieving the effect of waste slag recycling.
[0029] like Figure 2 and Figure 3 As shown, the guide pipe 9 has a diameter of 300mm and is embedded with a wear-resistant ceramic steel pipe. The inclination angle between the guide pipe 9 and the vertical mill 1 is greater than 80°. Through the structure of the guide pipe 9, the characteristic that the angle between the guide pipe 9 and the vertical mill 1 is greater than 80° allows the return fine powder to be directly fed into the vertical mill 1 through the guide pipe 9 when it is discharged, thereby achieving the effect of separating and conveying dry and wet materials, avoiding the mixing of the two and causing blockage of the pipeline, thus improving the material conveying effect of the device and the operating efficiency of the user, and preventing the dust effect from harming the human body.
[0030] like Figure 1 and Figure 2 As shown, wet slag is placed on top of the feed belt 6, and the return hopper 4 is filled with return fine powder. Through the structure of the return hopper 4, the return hopper 4 can not only receive the wet slag to cooperate with the feed belt 6 so that both the second return belt 5 and the feed belt 6 can transport the wet slag, thereby improving the operating efficiency of the device, but also allow the return fine powder to enter the vertical mill 1 without the need to use a conveyor belt to transport the powdery material, thereby reducing the generation of dust and avoiding dust from causing harm to the employees.
[0031] The technical solution provided by this utility model involves discharging wet slag through the discharge pipe 8 onto the first return conveyor belt 2 during operation. The wet slag then enters the return hopper 4 via the cooperation of the first return conveyor belt 2 and the return bucket elevator 3. The second return conveyor belt 5 facilitates automatic return of the wet slag. Simultaneously, the user can also transport the wet slag via the mill feed belt 6, thereby improving the automation of the device. After the wet slag is discharged, the return fine powder can be directly poured into the return hopper 4. The second return conveyor belt 5 stops operating, allowing the return fine powder to directly enter the vertical mill 1 through the guide pipe 9 to mix with the wet slag. This avoids the agglomeration of dry and wet materials, preventing pipe blockage and improving the user's work efficiency. Furthermore, the separation and conveying of dry and wet materials during operation prevents the return fine powder from being blown up, thus reducing the risk of injury to employees and improving the safety of the device during operation.
[0032] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0033] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as ROM / RAM, magnetic disk, optical disk, etc.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
