Description
Technical Field
[0001] The present application relates to the technical field of material discharge chute, and in particular to a novel material discharge inclined tee structure. Background Art
[0002] The process of loading alloy materials and bulk materials into the converter requires the use of a guided chute, that is, a material discharge chute, which is set between the flue body and the converter mouth. By adjusting the discharge direction of the material discharge chute, the material can be accurately loaded into the furnace, thereby improving the precision operation rate of steelmaking.
[0003] The traditional inclined three-way structure of material discharge is a straight material discharge chute, which directly loads the material into the furnace. During long-term operation, the material will not only wash the inner wall of the material discharge chute, causing the material discharge chute to deform and cause leakage accidents, but also the material will have a large impact force due to its height and direction, and will frequently collide with the flue charging sleeve spare parts connected to the outlet of the material discharge chute, thereby causing the charging sleeve itself to leak, affecting production costs and safe production.
[0004] In view of this, we propose a new type of inclined tee structure for cutting materials to better solve the above technical problems. Summary of the invention
[0005] The purpose of the embodiments of the present application is to provide a new type of inclined three-way structure for material discharge, which can solve the technical problem that the material discharge pipe is easily affected by impact and causes leakage.
[0006] An embodiment of the present application provides a novel inclined tee structure for material unloading, including an inclined tee chute, a first material restraint component, a second material restraint component, a first reinforcement component and a second reinforcement component. The inclined tee chute includes a straight pipe and an inclined pipe connected to each other. The first material restraint component is provided with a first baffle, which is arranged in the inclined pipe. The second material restraint component is provided with a second baffle, which is arranged in the straight pipe and close to the connecting position between the straight pipe and the inclined pipe. The first reinforcement component is fitted on the inclined pipe and is arranged on opposite sides of the inclined pipe with the first baffle. The second reinforcement component is arranged on the straight pipe and is located on the same side of the straight pipe as the second baffle.
[0007] Furthermore, the first material restraining assembly is also provided with a connecting seat, the inclined tube is provided with a connecting groove, and the first baffle extends out of the inclined tube through the connecting groove to be connected to the connecting seat for blocking the material and changing the impact speed and direction of the material.
[0008] Furthermore, the first baffle is configured as a meniscus to match the shape of the inner wall of the inclined tube.
[0009] Furthermore, the height of the second baffle is set to 1 / 4-1 / 3 of the inner diameter of the straight tube.
[0010] Furthermore, the first reinforcement member and the second reinforcement member are respectively configured as semicircular plates to fit the tube wall of the inclined tube / the straight tube.
[0011] Furthermore, at least two second baffles are provided and arranged at intervals, and the height of the second baffle located in front of the material flow is higher than the height of the second baffle located at the rear.
[0012] Furthermore, the first baffle is arranged at a position of the inclined tube close to the straight tube.

[0027] See also Figure 1 As shown, the novel inclined tee structure for material discharge described in this embodiment includes an inclined tee chute 1, a first material restraining component 2, a second material restraining component 3, a first reinforcement 4 and a second reinforcement 5. The inclined tee chute 1 includes a straight pipe 11 and an inclined pipe 12 connected to each other. The first material restraining component 2 is provided with a first baffle 21, and the first baffle 21 is arranged in the inclined pipe 12. The second material restraining component 3 is provided with a second baffle 31, and the second baffle 31 is arranged in the straight pipe 11 and close to the connecting position between the straight pipe 11 and the inclined pipe 12. The first reinforcement 4 is fitted on the inclined pipe 12 and is arranged on opposite sides of the inclined pipe 12 with the first baffle 21. The second reinforcement 5 is arranged on the straight pipe 11 and is located on the same side of the straight pipe 11 as the second baffle 31.
[0028] Specifically, the first baffle 21 is disposed at a position where the inclined tube 12 is close to the straight tube 11 .
[0029] The present embodiment has a simple structure and a reasonable design, wherein the first material restraint component 2 can withstand the impact force of the material, thereby changing the impact speed and direction of the material, and avoiding the impact of falling from the inclined tube 12 into the straight tube 11, and the second material restraint component 3 can form a buffer zone on the straight tube 11 to reduce the impact of the material, so that the material can smoothly enter the furnace and effectively extend the service life, wherein the first reinforcement 4 and the second reinforcement 5 can provide reinforcement and protection, thereby further improving the service life of the inclined tube 12 and the straight tube 11, avoiding the wear of the inner wall of the chute caused by the material for a long time, causing the occurrence of material leakage accidents, and ensuring stable material unloading and use.
[0030] In some embodiments, see Figure 2 As shown, the first material restraining component 2 is also provided with a connecting seat 22, the inclined tube 12 is provided with a connecting groove 13, and the first baffle 21 extends out of the inclined tube 12 through the connecting groove 13 to be connected with the connecting seat 22 for blocking the material and changing the impact speed and direction of the material.
[0031] In this embodiment, by connecting the first baffle plate 21 to the connecting seat 22, it is convenient to pull the first baffle plate 21 out of the inclined tube 12 through the connecting seat 22 after being used for a period of time for replacement, thereby ensuring the material blocking effect.
[0032] In some embodiments, the first baffle 21 is configured as a meniscus to match the shape of the inner wall of the inclined tube 12 .
[0033] In this embodiment, a meniscus is provided on the first baffle plate 21 to facilitate the coordination with the inner wall shape of the inclined tube 12 for material blocking. The structure is simple and the adaptability is good, so that the material can be better blocked, the boring impact can be reduced, and the service life of the material tube can be extended.
[0034] In some embodiments, the height of the second baffle 31 is set to 1 / 4-1 / 3 of the inner diameter of the straight tube 11.
[0035] In this embodiment, by setting the height of the second baffle 31 to a reasonable range, the material falling from the inclined tube 12 can form a material buffer layer to prevent the material from directly impacting the tube wall, thereby extending the service life of the straight tube 11. Specifically, in this embodiment, the straight tube 11 also has a certain inclination to cooperate with the furnace body for material dropping.
[0036] In some embodiments, the first reinforcement member 4 and the second reinforcement member 5 are respectively configured as semicircular plates to fit the tube wall of the inclined tube 12 / the straight tube 11 .
[0037] In this embodiment, by providing a semicircular reinforcement piece, the strength of the material pipe can be effectively improved, thereby cooperating with the two baffles to effectively extend the service life of the material pipe.
[0038] In some embodiments, see Figure 3 As shown, at least two second baffles 31 are provided and arranged at intervals, and the height of the second baffle 31 located in front of the material flow is higher than the height of the second baffle 31 located at the rear.
[0039] Such a setting in the present embodiment is mainly to form a triangular-shaped buffer material belt through cooperation, so that the material directly impacts the buffer belt instead of impacting the inner wall of the pipeline, thereby effectively extending the service life of the pipeline and achieving a stable material discharge effect.
[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
