[0002] The application of vanadium-titanium slag is currently quite extensive. It can not only be used in the metallurgical industry to improve the quality and performance of steel, but also in the field of environmental protection to recycle vanadium and titanium resources and reduce environmental pollution. It can also be used in the building materials industry and the chemical industry to manufacture high-strength building materials and promote chemical reactions.

[0003] Currently, vanadium-titanium slag powder is typically screened using a vibrating screen. This screen consists of an inclined housing and a vibrating motor mounted outside the housing. The housing has a feed inlet at the top, a powder outlet at the bottom, and a lump outlet on the side of the bottom. A screen is installed between the two outlets. Pour vanadium-titanium slag into the feed inlet, and the vibrating motor is activated to vibrate the housing. The vanadium-titanium slag powder falls below the screen and is discharged from the powder outlet. Lumps of vanadium-titanium slag vibrate above the screen to the lump outlet before being discharged.

[0004] Since the vanadium-titanium slag is separated into powder and blocks by a vibrating screen, the vanadium-titanium slag powder often diffuses at the powder outlet and the block outlet, resulting in waste of vanadium-titanium slag powder and pollution of the environment. Utility Model Content

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described are only part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] The screening device for producing vanadium-titanium slag powder provided by the present invention is now described.

[0023] like Figure 1 As shown, one embodiment of the utility model provides a screening device for the production of vanadium-titanium slag powder, including a vibrating screen body 1 with a powder outlet 11 and a block outlet 12 at its tail, and also including a powder collecting box 2 arranged below the powder outlet 11, and an elastic sealing component 3 is provided between the powder collecting box 2 and the vibrating screen body 1, and the elastic sealing component 3 is used to elastically seal the powder outlet 11 and the powder collecting box 2; a block conveyor belt 4 located below the block outlet 12 is provided at the tail of the vibrating screen body 1, and a collecting mechanism 5 for collecting powder at the block outlet 12 is provided at the tail of the vibrating screen body 1.

[0024] Compared with the prior art, the screening device for vanadium-titanium slag powder production provided in this embodiment collects the vanadium-titanium slag powder discharged from the powder outlet 11 through the powder collecting box 2, and realizes elastic sealing between the powder outlet 11 and the powder collecting box 2 through the elastic sealing component 3, which greatly reduces the diffusion of vanadium-titanium slag powder at the powder outlet 11; the block conveyor belt 4 recovers and conveys the vanadium-titanium slag blocks discharged from the block outlet 12, and at the same time, the collecting mechanism 5 collects the powder diffused at the block outlet 12 for recycling, which greatly reduces the overall waste of vanadium-titanium slag powder and achieves the effect of protecting the environment.

[0025] like Figures 1 to 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0026] The elastic sealing assembly 3 includes an annular frame 31, an elastic support member 32 and a first soft pipe member 33. The annular frame 31 is located above the powder collecting box 2. The first soft pipe member 33 is arranged between the annular frame 31 and the powder collecting box 2. The elastic support member 32 is arranged between the annular frame 31 and the powder collecting box 2. The annular frame 31 is attached to the lower surface of the vibrating screen body 1 and surrounds the powder outlet 11.

[0027] When it is necessary to collect vanadium-titanium slag powder, the powder collecting box 2 with the elastic sealing assembly 3 is pushed under the powder outlet 11 until the top surface of the annular frame 31 is in contact with the lower surface of the vibrating screen and the powder outlet 11 is surrounded. This can achieve an elastic seal between the powder outlet 11 and the powder collecting box 2. The setting of the first soft pipe 33 can also greatly reduce the impact of the vibrating screen body 1 on the powder collecting box 2 during vibration, thereby improving the elastic sealing effect between the powder outlet 11 and the powder collecting box 2.

[0028] like Figures 1 to 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0029] The elastic support member 32 is a spring, and has multiple elastic support members 32 surrounding the first soft tube member 33 . When the top surface of the annular frame 31 is in contact with the lower surface of the vibrating screen body 1 , the elastic support member 32 is in a compressed state.

[0030] While pushing the powder collecting box 2 to below the powder outlet 11, press the annular frame 31 to make it lower than the lower surface of the vibrating screen body 1 to facilitate the movement of the powder collecting box 2. After the powder collecting box 2 has been moved, multiple elastic support members 32 push the annular frame 31 upward on all sides, further improving the sealing effect between the powder outlet 11 and the powder collecting box 2.

[0031] like Figures 1 to 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0032] The portion of the vibrating screen body 1 that contacts the annular frame 31 is made of steel, and a magnet (not shown in the figure) is embedded around the top surface of the annular frame 31 .

[0033] The arrangement of the magnets can make the annular frame 31 and the vibrating screen body 1 more stable after being attached, thereby improving the sealing stability between the vibrating screen body 1 and the powder collecting box 2 during vibration operation.

[0034] like Figure 1 and Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0035] The collecting mechanism 5 includes an extension tube 51, a collecting shell 52, a filter screen 53, a fan 54 and a filter element 55. The extension tube 51 is connected to the block material outlet 12, and the block material conveyor belt 4 is located below the tail outlet of the extension tube 51; the collecting shell 52 is connected to one side of the extension tube 51, and the collecting shell 52 is set at an opening on one side away from the extension tube 51, and the filter screen 53 is set at the connection between the collecting shell 52 and the extension tube 51; there are multiple fans 54 and they are set in a position close to its own opening in the collecting shell 52, and the filter element 55 is set in the collecting shell 52 and is used to filter powder.

[0036] The vanadium-titanium slag blocks enter the extension tube 51 from the block outlet 12, and while being transported in the extension tube 51, the powder surrounding the vanadium-titanium slag is sucked into the collecting shell 52 by the fan 54. The filter screen 53 is used to block the vanadium-titanium slag blocks. The powder entering the collecting shell 52 is blocked by the filter element 55 and remains in the collecting shell 52, so as to achieve the effect of centralized recovery of the powder discharged from the block outlet 12.

[0037] Specifically, in this embodiment, a cleaning door is provided on the side of the collecting shell 52 so as to periodically recycle the powder collected in the collecting shell 52 .

[0038] like Figure 1 and Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0039] The extension pipe 51 includes a connecting pipe 511, a second soft pipe fitting 512 and an inclined pipe 513. The connecting pipe 511 is connected to the block outlet 12 and is arranged at an angle. The block conveyor belt 4 is located below the bottom outlet of the inclined pipe 513; the second soft pipe fitting 512 is arranged vertically and connected between the connecting pipe 511 and the inclined pipe 513; the collecting shell 52 is connected to the bottom of the inclined pipe 513, and the filter screen 53 is located directly below the second soft pipe fitting 512 and is arranged at an angle following the inclined pipe 513.

[0040] The vanadium-titanium slag block first enters the connecting pipe 511 from the block outlet 12, then enters the second soft pipe 512, and then falls downward onto the filter screen 53 in the inclined pipe 513, which can make the powder attached to the vanadium-titanium slag block more completely separated and sucked into the collection shell 52, further improving the powder recovery efficiency.

[0041] Specifically, in this embodiment, the first soft tube 33 and the second soft tube 512 can be made of cloth bags or plastic hoses.

[0042] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0043] The filter element 55 is a non-woven fabric layer 551, which is provided with two non-woven fabric layers 551. Furthermore, a gap is left between the two non-woven fabric layers 551. The provision of two non-woven fabric layers 551 with a gap can improve the filtering effect of powder while ensuring gas circulation.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
