Description

Technical Field

[0001] This utility model relates to the field of steel slag powder selection technology, and more specifically, to a powder selection device after vertical mill processing. Background Technology

[0002] Steel slag is a type of solid waste discharged from steel plants. It is mainly composed of oxides of calcium, iron, silicon, magnesium, and small amounts of aluminum, manganese, phosphorus, etc. Currently, vertical grinding mills can be used to reprocess and reuse steel slag, which is beneficial to both the environment and industrial production.

[0003] Currently, the steel slag processed by vertical grinding mills contains metallic impurities and steel slag powder of different particle sizes. Therefore, it is necessary to separate the materials according to their material and particle size and collect them independently. However, the separation of metallic impurities and steel slag powder of different particle sizes currently needs to be completed in equipment in different areas, and there is a lack of an integrated steel slag powder classifier. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a powder selection device after vertical mill processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A powder classifier after vertical mill processing includes a classifier box, a vibrating motor, a feed hopper, a discharge port, a flange, a fully automatic drawer-type iron separator, a guide plate, and two sets of screening and conveying components.

[0007] The vibrating motor is fixed on the powder classifier, which includes a feed hopper and a discharge port. A first collection container is fixed on the powder classifier below the discharge port.

[0008] The end of the feed hopper is located inside the powder separator and is connected to the input end of a fully automatic drawer-type iron separator via a flange;

[0009] The guide plate is inclinedly installed inside the powder classifier and located below the output end of the fully automatic drawer-type iron remover. The end of the guide plate is spaced apart from the inner wall of the powder classifier.

[0010] Two sets of screening and conveying components with different particle sizes and distributed vertically are respectively inclinedly installed in the powder classifier box, and the two sets of screening and conveying components are respectively connected to the second collection container and the third collection container fixed on the powder classifier box.

[0011] Furthermore, the screening and conveying assembly includes a first arc-shaped screening element, a second arc-shaped screening element, a first feeding pipe, and a second feeding pipe. The first and second arc-shaped screening elements are inclinedly arranged inside the powder selection box and distributed vertically. The screen holes of the first arc-shaped screening element are larger than those of the second arc-shaped screening element. The first and second feeding pipes are both inclinedly arranged on the outer wall of the powder selection box and are respectively connected to the bottom of the first and second arc-shaped screening elements. The end of the first feeding pipe is connected to a second collection container, and the end of the second feeding pipe is connected to a third collection container.

[0012] The above scheme uses two sets of screening and conveying components, along with a vibrating motor, a discharge port, and a first collection container, to automatically select and independently collect and store steel slag powder according to its particle size.

[0013] Furthermore, a metal impurity auxiliary discharge component is provided below the guide plate, and a metal discharge port and a sealing component that cooperates with the metal discharge port are provided on the powder selection box.

[0014] Furthermore, the metal impurity auxiliary discharge assembly includes a second telescopic member and an extension plate. The bottom of the guide plate is provided with the second telescopic member, and the second telescopic member is connected to an extension plate that is in contact with and parallel to the bottom of the guide plate.

[0015] Furthermore, the sealing assembly includes a third telescopic component and a sealing plate. The powder selection box is provided with a third telescopic component, which is connected to a sealing plate that cooperates with the metal discharge port.

[0016] The above scheme first controls the movement of the second telescopic component, thereby driving the extension plate to contact the inner wall of the powder classifier. After the extension plate has finished moving, the third telescopic component is then controlled to move, thereby driving the sealing plate to move up to release the blockage of the metal discharge port. Finally, the controller controls the fully automatic drawer-type iron separator to automatically unload the material. Then, the metal impurities adsorbed on the high magnetic rod will automatically fall off and flow out from the metal discharge port into the metal collection container under the action of the vibration motor.

[0017] Furthermore, a star-shaped unloader is connected to the feed hopper via an auxiliary flange, and the star-shaped unloader is flexibly connected to the discharge end of the vertical mill.

[0018] In the above scheme, the steel slag powder material processed by the vertical mill is uniformly and quantitatively fed into the powder classifier box through the star-shaped unloader. At the same time, the flexible connection between the star-shaped unloader and the discharge end of the vertical mill can reduce the impact of the vibration motor on the vertical mill.

[0019] Furthermore, the metal discharge port is inclined and the powder selection box is provided with a metal collection container located below the metal discharge port.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Compared to existing technologies, this device combines magnetic separation and sieving functions for steel slag powder. It can first remove metal impurities from the material, and then classify the steel slag powder according to different particle sizes. Finally, the metal impurities and steel slag powder of different sizes can be collected into different containers according to their material and particle size. Therefore, it is not necessary to carry out the classification process in different areas. This device automatically and comprehensively performs the accurate classification process on the steel slag material processed by the vertical mill, resulting in better steel slag recycling and processing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0026] like Figure 1 As shown, a powder classifier after vertical mill processing includes a powder classifier box 1, a vibrating motor 101, a feed hopper 11, a discharge port 12, a flange 13, a fully automatic drawer-type iron separator 14 (which belongs to the prior art and its working principle is not described), a guide plate 15, and two sets of screening and conveying components.

[0028] The end of the feed hopper 11 is located inside the powder classifier 1 and is connected to the input end of the fully automatic drawer-type iron separator 14 via flange 13.

[0029] The guide plate 15 is inclinedly arranged inside the powder classifier 1 and located below the output end of the fully automatic drawer-type iron remover 14. The end of the guide plate 15 is spaced apart from the inner wall of the powder classifier 1.

[0030] Two sets of screening and conveying components with different particle sizes and distributed vertically are respectively inclinedly installed in the powder classifier 1, and the two sets of screening and conveying components are respectively connected to the second collection container and the third collection container fixed on the powder classifier 1 (the second collection container and the third collection container are shown in the figure but are not labeled).

[0031] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the screening and conveying assembly includes a first arc-shaped screening element 21, a second arc-shaped screening element 22, a first feeding pipe 23, and a second feeding pipe 24. The first arc-shaped screening element 21 and the second arc-shaped screening element 22 are inclinedly arranged inside the powder selection box 1 and are distributed vertically. The screen holes of the first arc-shaped screening element 21 are larger than those of the second arc-shaped screening element 22. The first feeding pipe 23 and the second feeding pipe 24 are both inclinedly arranged on the outer wall of the powder selection box 1 and are respectively connected to the bottom of the first arc-shaped screening element 21 and the bottom of the second arc-shaped screening element 22. The end of the first feeding pipe 23 is connected to the second collection container, and the end of the second feeding pipe 24 is connected to the third collection container.

[0032] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, a metal impurity auxiliary discharge component is provided below the guide plate 15, and a metal discharge port and a sealing component that cooperates with the metal discharge port are provided on the powder selection box 1.

[0033] Specifically, the metal impurity auxiliary discharge assembly includes a second telescopic member 31 and an extension plate 32. The bottom of the guide plate 15 is provided with the second telescopic member 31, and the second telescopic member 31 is connected to an extension plate 32 that is in contact with and parallel to the bottom of the guide plate 15.

[0034] Specifically, the sealing component includes a third telescopic member 34 and a sealing plate 35. The powder selection box 1 is provided with a third telescopic member 34, which is connected to a sealing plate 35 that cooperates with the metal discharge port. In a further optimization of the scheme, the metal discharge port is inclined and the powder selection box 1 is provided with a metal collection container located below the metal discharge port. The metal collection container is not labeled in the figure.

[0035] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, a star-shaped unloader 41 is connected to the feed hopper 11 via an auxiliary flange 13. The star-shaped unloader 41 is flexibly connected to the discharge end of the vertical mill. The vertical mill is not shown in the figure. The auxiliary flange 13 and the star-shaped unloader 41 are shown in the figure but are not labeled.

[0036] It should be noted that the vibration motor 101, the first telescopic component 16, the distance sensor 18, the second telescopic component 31, and the third telescopic component 34 are all electrically connected to the controller, which is not shown in the figure.

[0037] The working process of this utility model:

[0038] First, the steel slag processed by the vertical mill is fed into the powder classifier 1 through the feed hopper 11. Then, the star-shaped unloader 41 can achieve uniform feeding. The material then enters from the input end of the fully automatic drawer-type iron separator 14. The fully automatic drawer-type iron separator 14 is energized in advance, and several high magnetic rods inside it can adsorb and remove the metal impurities in the steel slag powder. Then, the steel slag powder after the metal impurities are removed will flow out from the output end of the fully automatic drawer-type iron separator 14.

[0039] After removing metal impurities, the steel slag powder moves along the guide plate 15 while the vibrating motor 101 is in operation. It eventually flows onto the first arc-shaped screen 21. The larger steel slag powder particles remain on the first arc-shaped screen 21 and move along the bottom of the first arc-shaped screen 21, eventually being injected into the second collection container through the first discharge pipe 23. Similarly, the medium-sized steel slag powder particles remain on the second arc-shaped screen 22 and move along its bottom, eventually being injected into the third collection container through the second discharge pipe 24. The smallest steel slag powder particles are injected into the first collection container to complete storage and collection. At this point, the steel slag powder selection process ends.

[0040] Then, the controller controls the movement of the second telescopic component 31, thereby driving the extension plate 32 to contact the inner wall of the powder sorting box 1 (as per the instruction manual). Figure 1 As shown, it should be noted that during the selection process of steel slag powder, the extension plate 32 and the inner wall of the selection box 1 are spaced apart to avoid affecting the falling of steel slag powder and the metal discharge port 33 is in a blocked state to prevent the steel slag powder from overflowing.

[0041] After the extension plate 32 completes its movement, the controller then controls the third telescopic component 34 to move, thereby driving the sealing plate 35 to move upward to release the blockage of the metal discharge port 33. Finally, the controller controls the fully automatic drawer-type iron separator 14 to cut off the power and unload the material. Then, the metal impurities adsorbed on the high magnetic rod can fall off and flow out from the metal discharge port into the metal collection container under the action of the vibration motor. Thus, the steel slag powder material is independently selected and effectively separated according to its material and particle size.

[0042] Compared to existing technologies, this device combines magnetic separation and sieving functions for steel slag powder. It can first remove metal impurities from the material, and then classify the steel slag powder according to different particle sizes. Finally, the metal impurities and steel slag powder of different sizes can be collected into different containers according to their material and particle size. Therefore, it is not necessary to carry out the classification process in different areas. This device automatically and comprehensively performs the accurate classification process on the steel slag material processed by the vertical mill, resulting in better steel slag recycling and processing.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
