Description

Technical Field

[0001] The utility model relates to the technical field of steel slag processing, in particular to a screening device for conveying steel slag. Background Art

[0002] Steel slag is a by-product of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts formed by the reaction of these oxides with solvents.

[0003] The steel slag needs to be transported by roller conveyors during the processing. However, the steel slag transported in batches may have inconsistent sizes (i.e., large-sized steel slag). If the large-sized steel slag flows directly to the next area for processing, it will affect the subsequent processing efficiency and quality. Therefore, the large-sized steel slag needs to be blocked and left behind, and then the roller conveyor is manually stopped. After the roller conveyor is stopped, the large-sized steel slag is manually transferred to the crushing equipment for secondary processing using tools. This puts a lot of labor intensity on the staff, and there is an urgent need for a set of equipment that can automatically screen and transfer the large-sized steel slag for processing during the steel slag transportation process. Utility Model Content

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a screening device for conveying steel slag.

[0007] This device does not require manual supervision by the side of the roller conveyor and manual completion of the roller conveyor stoppage and manual transfer of large-grained slag to the crushing equipment. It automatically completes the blocking, adsorption, transfer and unloading processes of large-grained slag to ensure the subsequent processing efficiency and quality of the slag.

[0010] Furthermore, the discharge port of the crushing equipment is connected to an inclined conveying pipe, and the end of the conveying pipe is connected to the feeding equipment.

[0011] Furthermore, the loading equipment adopts a bucket elevator, the end of the conveying pipe is above the feed port of the bucket elevator, the discharge port of the bucket elevator is above the belt of the roller conveyor, and the bucket elevator and the mounting rod are spaced apart in front and back.

[0013] Furthermore, a CCD camera is provided on the roller conveyor belt.

[0014] The above solution can capture and feed back the information to the remote control room through a CCD camera.

[0016] The above solution effectively extends the service life of the curved plate through the wear-resistant belt.

[0017] Furthermore, a vibration motor is provided on the feeding channel.

[0018] The above solution avoids the phenomenon of unsmooth discharge of steel slag in the discharge channel by using a vibration motor.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] Compared with the existing technology, this device does not require manual inspection and manual shutdown of the roller conveyor and manual transfer of large-grained steel slag to the crushing equipment.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0027] like Figures 1 to 3 As shown, a screening device for conveying slag includes a mounting platform 1 and a crushing device 4 on one side of the mounting platform 1. The crushing device adopts a slag crusher, which belongs to the existing technology and is not improved. A roller conveyor 2 is provided on the mounting platform 1. A drive box 11 and an inclined discharge channel 3 are respectively provided on the mounting platform 1 on both sides of the roller conveyor 2. A telescopic component is provided in the drive box 11, and the telescopic component is connected to a mounting rod 12 with an L-shaped main body shape. A horizontal moving component is provided on the mounting rod 12, and an arc plate 15 is provided on the horizontal moving component. A cylinder 16 is provided on the arc plate 15, and the cylinder 16 is connected to an electromagnetic plate 17. One end of the discharge channel 3 is below the belt of the roller conveyor 2 and a discharge port 31 with a size larger than the arc plate 15 is opened on the discharge channel 3. The other end of the discharge channel 3 is connected to the inside of the crushing device 4.

[0028] Specifically, the horizontal movement component includes an electric push rod 13 and a slider 14 . The electric push rod 13 is horizontally arranged on the mounting rod 12 . The electric push rod 13 is connected to the slider 14 that slides with the mounting rod 12 . The slider 14 is provided with an arc plate 15 .

[0029] In a further refinement of the embodiment of the present invention, a wear-resistant belt is provided on the arc plate 15 ; the wear-resistant belt is not shown in the figure, and the service life of the arc plate 15 can be effectively extended by the wear-resistant belt.

[0030] In a further optimization of the embodiment of the present invention, a vibration motor is provided on the discharge channel 3, which is not shown in the figure; the vibration motor is used to avoid the phenomenon of unsmooth discharge of steel slag in the discharge channel 3.

[0031] It should be noted that the roller conveyor 2, the crushing equipment 4, the telescopic assembly, the electric push rod 13, the cylinder 16 and the electromagnetic plate 17 are all electrically connected to the controller, which is not shown in the figure.

[0032] The workflow of this utility model:

[0033] First, the controller controls the roller conveyor 2 to transport the steel slag. At the same time, the telescopic component works so that the lower end of the arc plate 15 is close to the belt of the roller conveyor 2 and the distance between the two is pre-set in the controller. At this time, the arc plate 15 can block and retain the large-grained steel slag in the steel slag, and the small-grained steel slag can pass smoothly. After the roller conveyor 2 runs for a pre-set time interval, the controller controls the roller conveyor 2 to stop working briefly. During the short stoppage, the controller controls the cylinder 16 to work so that the electromagnetic plate 17 approaches the large-grained steel slag from top to bottom. When the electromagnetic plate 17 contacts the large-grained steel slag, the controller controls the electromagnetic plate 17 to be energized to achieve the adsorption of the large-grained steel slag. After the adsorption is completed, the telescopic component first drives the arc plate 15 to move up to a position that does not affect the subsequent water The controller then controls the electric push rod 13 to work and drive the curved plate 15 to move to the right along the horizontal rod of the mounting rod 12. When the curved plate 15 moves to the top of the discharge port 31, the controller immediately controls the electric push rod 13 to stop working. Then the controller controls the electromagnetic plate 17 to cut off the power, so that the large-grained steel slag can be unloaded and transferred into the discharge channel 3. The large-grained steel slag is then subjected to secondary processing in the crushing equipment 4 to reduce its particle size for subsequent secondary utilization. After the unloading and transfer of the large-grained steel slag is completed, the curved plate 15 immediately moves back to the initial position (i.e., the lower end of the curved plate 15 is close to the belt of the roller conveyor 2 and the distance between the two is determined), and a new round of screening operation is immediately started. The adsorption force of the electromagnetic plate 17 can be adjusted to ensure the adsorption effect of a number of large-grained steel slags.

[0034] Compared with the existing technology, this device does not require manual inspection and manual completion of the roller conveyor 2 and the manual transfer of large-grained steel slag to the crushing equipment 4. It automatically completes the blocking, adsorption, transfer and unloading processes of large-grained steel slag to ensure the subsequent processing efficiency and quality of steel slag, and realizes automatic screening and transfer to complete the crushing process during the steel slag transportation process, which significantly improves the degree of automation.

[0035] In some embodiments, the discharge port of the crushing device 4 is connected to an inclined conveying pipe 5, and the end of the conveying pipe 5 is connected to the feeding device;

[0036] The refinement of the above embodiment scheme is as follows: Figure 3 As shown, the feeding equipment adopts a bucket elevator 6, the end of the conveying pipe 5 is above the feeding port of the bucket elevator 6, the discharge port of the bucket elevator 6 is above the belt of the roller conveyor 2, and the bucket elevator 6 and the mounting rod 12 are spaced apart from each other. This embodiment can realize the secondary feeding and conveying process of small-sized steel slag after crushing to the roller conveyor 2 through the bucket elevator 6, and the degree of automation is better.

[0037] In other embodiments, a CCD camera is provided on the roller conveyor belt 2. The CCD camera is not shown in the figure and its principle belongs to the prior art and is not described. The CCD camera is electrically connected to the controller. This embodiment can take pictures through the CCD camera and feed back to the remote control room. Then the display screen in the control room can display the conveying and screening status of the slag in real time, avoiding process interruption or abnormal shutdown caused by failure of the roller conveyor belt 2, telescopic component or horizontal moving component.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
