Abstract
Description

[0001] This utility model belongs to the field of material screening technology, and specifically relates to a material vibrating screen. Background Technology
[0002] In the production process of using a blast furnace, in order to ensure the stability of the blast furnace charge, the material is usually screened to separate materials of different sizes, thereby improving the production efficiency and product quality of the blast furnace.
[0003] In traditional screening processes, the material is mainly concentrated near the center line of the screen surface when it is fed from the nozzle. The material cannot be spread evenly on the entire screen surface, resulting in a thick material layer on the screen surface. During the screening process, the material layer cannot be screened through, which increases the proportion of small particles in the furnace charge. This is not conducive to the permeability of the blast furnace and easily causes airflow fluctuations, thereby reducing the screening effect of the material and causing the screen to wear out too quickly in some areas, shortening its service life.

[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This utility model provides a material vibrating screen comprising a screen body, a vibrating feeder, guide plates, and partitions. One end of the screen body is provided with a feed plate, and the material moves along the feed plate and the screen body for screening. The vibrating feeder is installed below the screen body. Two guide plates are provided, with one end of each guide plate installed on the screen body near the feed plate.

At the same time, the vibrating feeder drives the screen body to vibrate, making the material spread evenly within the screen body, further improving the screening effect. Therefore, this material vibrating screen, through the baffles and vibrating feeder, makes the material distribution within the screen body more uniform, improving the screening effect.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0026] This utility model provides a material vibrating screen, solving the technical problem that uneven material distribution and inconsistent thickness on the screen mesh reduce the screening effect during current material screening processes. The material vibrating screen includes a screen body 1, a vibrating feeder 3, a guide plate 4, and a partition plate 5, wherein:
[0027] The screen body 1 is provided with a feed plate 2 at one end. The screen body 1 is used to screen materials. The screen body 1 is installed at an inclination. The material is placed at the top of the screen body 1 and moves along the screen body 1 to screen the material. The feed plate 2 is provided at one end of the screen body 1. The material moves from the feed plate 2 towards the screen body 1 and then enters the screen body 1 and moves along the axial direction of the screen body 1 to screen the material.
[0028] The vibrating feeder 3 is installed below the screen body 1. The vibrating feeder 3 is used to generate continuous vibration when screening materials. As the material moves along the screen body 1, the material can be more evenly distributed on the screen body 1 under the action of vibration. At the same time, it can also make the material spread more evenly on the screen body 1, reducing the insufficient screening of material at thicker areas when the material distribution is uneven, thus affecting the screening of the material. It also reduces the agglomeration of material that leads to increased wear on the screen body 1.
[0029] There are two guide plates 4. One end of each guide plate 4 is installed on the end of the screen body 1 near the feed plate 2. The guide plates 4 abut against the feed plate 2. The guide plates 4 are used to guide the material to be screened into the screen body 1. The end of any guide plate 4 away from the screen body 1 extends away from the other guide plate 4. That is, the distance between the two guide plates 4 gradually increases from the end of the two guide plates 4 near the screen body 1 to the other end. When screening the material, the material moves towards the screen body 1 between the two guide plates 4. As the distance between the two guide plates 4 decreases, the material can be fully replenished on the screen body 1. The feed plate 2 and the two guide plates 4 form a feeding area. When screening the material, the material first accumulates in the feeding area and then passes through the screen body 1 for screening.
[0030] Baffles 5 are installed in the feeding area and abut against the feeding plate 2 to block material from passing between the baffles 5 and the feeding plate 2. Multiple baffles 5 divide the feeding area into multiple sub-areas, each of which is connected to the screen body 1. Material is supplied to different parts of the screen body 1 through different sub-areas. The width of the sub-area gradually increases from one end of the feeding plate 2 near the screen body 1 to the other end. As the width of the sub-area gradually decreases, when material enters the screen body 1 from the sub-area, the material can be replenished into the screen body 1 in a timely manner. At the same time, due to the obstruction of the baffles 5, the material can be more evenly distributed in the screen body 1, thereby making the screening of the material more uniform and reducing the accumulation of material in the middle of the screen body 1.
[0031] With the above structure, the material vibrating screen provided by this utility model, when screening materials, first slides along the top of the feed plate 2 towards the screen body 1. As the material slides, due to the separation by the partition 5, the material enters multiple sub-regions under the obstruction of the partition 5. As the material continues to slide, the width of the sub-regions gradually decreases. Therefore, when the material enters the screen body 1 from the sub-region, it can be replenished into the screen body 1 in a timely manner. Simultaneously, due to the obstruction of the partition 5, the material can be more evenly distributed within the screen body 1, resulting in more uniform screening. At the same time, the vibrating feeder 3 drives the screen body 1 to vibrate, making the thickness of the material spread evenly within the screen body 1, further improving the screening effect. Therefore, this material vibrating screen, through the partition 5 and the vibrating feeder 3, makes the material distribution within the screen body 1 more uniform, improving the screening effect.
[0032] An optional implementation of this embodiment is as follows: In order to better enable the material to move evenly along the axial direction of the screen body 1, the material vibrating screen further includes an extension plate 6. One end of the extension plate 6 is installed on the end of the partition plate 5 near the screen body 1, and the other end extends towards the screen body 1. This allows the material to continue to be blocked by the extension plate 6 after passing through the partition plate 5, so that the material can always be evenly distributed on the screen body 1 when entering the screen body 1. The axial direction of the extension plate 6 is parallel to the axial direction of the screen body 1. That is, after the material enters the screen body 1, the material moves in a direction parallel to the extension plate 6 under the obstruction of the extension plate 6, thereby reducing the material from moving in other directions, so that the material is more evenly distributed on the screen body 1 when sliding and screening inside the screen body 1.
[0033] An optional implementation of this embodiment is as follows: In order to make the material screened by the screen body 1 more uniform, the vibrating screen also includes a fixing member 7. The end of the partition plate 5 near the extension plate 6 is rotatably mounted on the extension plate 6. By rotating the partition plate 5, the angle of the partition plate 5 is adjusted, thereby adjusting the width of the sub-region according to the sliding condition of the material on the screen body 1. By changing the width of the sub-region, the amount of material sliding from the sub-region to the screen body 1 is adjusted according to the sliding condition of the material on the screen body 1, so that the material is screened on the screen body 1 in a more uniform amount and speed. The fixing member 7 is mounted on the partition plate 5. When the partition plate 5 rotates, the fixing member 7 rotates with the partition plate 5. When the angle of the partition plate 5 is adjusted appropriately, the fixing member 7 abuts against the feed plate 2, thereby fixing the position of the partition plate 5. In one embodiment provided in this embodiment, the fixing member 7 is a screw. The fixing member 7 can also be other components that can fix the partition plate 5 to the feed plate 2.
[0034] An optional implementation of this embodiment is as follows: A groove 21 is provided on the feed plate 2. The extension direction of the groove 21 is perpendicular to the extension direction of the screen body 1. An extension plate 6 is slidably installed in the groove 21. The extension plate 6 slides along the groove 21 to adjust the width of the sub-area. According to the sliding situation of the material on the screen body 1, the position of the extension plate 6 is adjusted to change the sliding position of the material, reduce the accumulation of material in a certain area on the screen body 1, and make the material more evenly distributed on the screen body 1.
[0035] An optional implementation of this embodiment is as follows: The screen body 1 includes a screen 11, side plates 12, and a bottom plate 13. The screen 11 is used for screening materials. There are two side plates 12, which are respectively installed on both sides of the screen 11 to prevent materials from sliding out of the screen 11 from both sides. The feed plate 2 is installed on one end of the two side plates 12 and abuts against the screen 11, so that the materials on the feed plate 2 can slide onto the screen 11 for screening. The bottom plate 13 is installed on the side plates 12 and is located below the screen 11 to receive the materials screened by the screen 11, so that the materials on the bottom plate 13 are separated from those on the screen 11.
[0036] An optional implementation of this embodiment is as follows: In order to reduce the material accumulation in the middle of the screen 11 due to deformation of the screen 11, the vibrating screen further includes a support plate 8. The support plate 8 is installed between the screen 11 and the bottom plate 13. The side of the screen 11 closest to the bottom plate 13 abuts against the support plate 8. When screening materials, the screen 11 will deform towards the bottom plate 13 under the action of gravity. After long-term use, the middle of the screen 11 is closer to the bottom plate 13, making it easier for the material to accumulate in the middle of the screen 11, resulting in uneven distribution of the material on the screen 11. The support plate 8 is used to support the screen 11, thereby reducing the deformation of the screen 11. The number of grids can be increased or decreased according to the usage.
[0037] An optional implementation of this embodiment is as follows: It further includes a baffle 9, one end of which is rotatably installed inside the screen body 1. When feeding stops, the other end of the baffle 9 abuts against the bottom of the screen body 1 under gravity. During feeding, the material pushes the baffle 9 to rotate and slides along the screen body 1 between the baffle 9 and the bottom of the screen body 1. During material screening, the material slides downwards along the screen mesh 11 and gradually accumulates on the side of the baffle 9 near the partition 5. As the material accumulates, it gradually pushes the baffle 9 away from the partition 5 under gravity, allowing the material to pass under the baffle 9. As the material moves, one end of the baffle 9 abuts against the top of the material, smoothing it and making the material thickness more uniform. Simultaneously, under the vibration of the vibrating feeder 3, materials with a larger screen mesh 11 are more likely to move to both sides, thus improving the screening effect of the material on the screen body 1.
[0038] An optional implementation of this embodiment is as follows: A discharge trough 10 is provided at one end of the bottom plate 13 away from the feed plate 2. The discharge trough 10 is used to discharge the material that moves along the bottom plate 13 through the screen 11. The discharge direction of the discharge trough 10 is perpendicular to the extension direction of the bottom plate 13, so as to separate the material that moves through the screen 11 from the material that moves through the bottom plate 13.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
