Description

Technical Field

[0001] The utility model relates to the technical field of slag dehydration, in particular to a high-efficiency dehydration device for yellow phosphorus electric furnace slag. Background Art

[0002] Yellow phosphorus production companies mostly use the electric furnace method to produce phosphorus. Phosphate ore, white coal, and silica are added into the electric furnace in a certain ratio. The elemental phosphorus in the phosphate ore undergoes a reduction reaction at high temperature and is collected in the form of a gas. The remaining slag after the reaction is regularly discharged from the electric furnace, and after being quenched with water and cooled, it is sold to downstream cement products companies as a by-product.

[0003] The yellow phosphorus slag has a high residual water content after water quenching in the slag flusher. A large amount of phosphorus-containing residual water will precipitate during transportation and slag bin caching before loading, making it extremely difficult to control on-site sewage and flue gas, resulting in a poor environment and a large environmental risk. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the water content of slag is relatively high after water quenching, and direct transportation into a warehouse for storage is likely to cause environmental pollution.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a high-efficiency dehydration device for yellow phosphorus electric furnace slag, including a vibrating frame with a U-shaped cross-section, a feeding belt arranged above the feeding end of the vibrating frame, a unloading belt arranged below the unloading end of the vibrating frame and a water trough arranged below the drain outlet at the bottom of the vibrating frame. The vibrating frame is supported on the top of the mounting frame by a spring, and a cam structure driven by a vibration motor to rotate horizontally and a drain plate arranged at an angle with water filtering holes are arranged in the vibrating frame. A roller belt is arranged horizontally above the drain plate to squeeze the material above the drain plate.

[0006] Preferably, the drain plate includes an inclined drain plate, a straight drain plate and a feed plate. The inclined drain plate is arranged obliquely, the straight drain plate is arranged horizontally, the inclined drain plate and the straight drain plate are continuously and staggeredly connected, and the feed plate is arranged obliquely at the feed end of the drain plate.

[0007] Preferably, the drain inclined plate, drain straight plate and feed plate all include a grid structure in the middle and straight plates laid on the top and bottom surfaces of the grid structure, and the water filter holes are arranged on the straight plates.

[0008] Preferably, the roller belt is arranged directly above the unloading plate, and the rotation direction of the side of the roller belt opposite to the unloading plate is the same as the flow direction of the material on the unloading plate, and the distance between the rotating roller of the roller belt close to the material unloading end and the unloading plate is smaller than the distance between the rotating roller at the other end and the unloading plate.

[0009] Preferably, a support plate is fixedly provided inside the vibration frame, the support plate is located on the inner side of the roller belt and the bottom surface of the support plate is in contact with the inner bottom surface of the roller belt.

[0010] Preferably, the outer wall of the roller belt is provided with pusher protrusions arranged at equal intervals.

[0011] Preferably, the cam structure is a vibration roller that is horizontally rotatably arranged at the top of the vibration frame, and the cross section of the vibration roller forms a cam structure.

[0012] 1. The utility model provides a high-efficiency dehydration device for yellow phosphorus electric furnace slag. By setting a vibration frame and arranging a drain plate in the vibration frame, the vibration frame can drain water in the slag from the filter holes on the drain plate during vibration, and discharge the water into the water tank through the drain port at the bottom of the vibration frame, thereby achieving dehydration of the slag.

[0013] 2. A roller belt is set at the tail end of the drain plate. During the vibration of the vibrating frame, the slag can be evenly spread on the surface of the drain plate. The roller belt can roll the slag evenly to further clean the moisture of the slag.

[0015] 4. The drain plate is equipped with a drain inclined plate and a drain straight plate, which can smoothly transport the slag and ensure that the slag is effectively dehydrated in the front section. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 and Figure 2As shown, the utility model provides a high-efficiency dehydration device for yellow phosphorus electric furnace slag, including a vibration frame 1 with a U-shaped cross-section, a feeding belt 2 arranged above the feeding end of the vibration frame 1, a unloading belt 3 arranged below the unloading end of the vibration frame 1 and a water trough 7 arranged below the drainage outlet 6 at the bottom of the vibration frame 1, the vibration frame 1 is supported on the top of the mounting frame 4 by a spring, and a vibration motor 5 is provided in the vibration frame 1 to drive a horizontally rotating cam structure and an inclined drain plate with a water filter hole, and a roller belt 14 is horizontally arranged above the drain plate to squeeze the material above the drain plate.

[0021] The slag is conveyed to the drain plate by the feeding belt 2. The drain plate is arranged inclined. One end of the drain plate below the feeding belt 2 is higher than the other end of the drain plate. After the slag is on the drain plate, the cam structure is driven to rotate by the vibration motor 5. The vibration frame 1 vibrates up and down during the rotation. The vibration frame 1 will drive the slag on the drain plate to vibrate during the vibration process, and the water in the slag will flow out from the water filter holes. The water enters the inner bottom of the vibration frame 1 and is discharged from the drain port 6 at the bottom of the vibration frame 1 and enters the water tank 7 to be collected. The remaining slag is discharged along the drain port 6 at the bottom of the vibration frame 1. The plate continues to flow, and after the slag flows to the bottom of the roller belt 14, since the roller belt 14 is arranged obliquely relative to the drain plate, the roller belt 14 is driven by the roller motor 8 on the outer wall of the vibration frame 1 to rotate. The rotation of the roller belt 14 can push the slag to continue to flow forward. At the same time, the gap between the roller belt 14 and the drain plate is continuously reduced during the flow process, thereby squeezing the slag and further squeezing out the moisture in the slag, further improving the dehydration effect of the slag. Finally, the slag falls from the discharge end of the drain plate and enters the discharge belt 3 for external discharge.

[0022] A reinforcing rod 10 is horizontally arranged at the top of the vibration frame 1 to enhance the strength of the vibration frame 1 .

[0023] like Figure 2 As shown. The drain plate includes a drain inclined plate 11, a drain straight plate 12 and a feed plate 13. The drain inclined plate 11 is arranged obliquely, and the drain straight plate 12 is arranged horizontally. The drain inclined plate 11 and the drain straight plate 12 are continuously staggered and connected, and the feed plate 13 is arranged obliquely at the feed end of the drain plate. The drain inclined plate 11 facilitates the slag to continue to move downward, and the drain straight plate 12 has a slowing effect on the movement of the slag, so that the slag can stay on the drain plate for more time to ensure the quality of dehydration. The feed plate 13 cooperates with the roller belt 14.

[0024] like Figure 2As shown, in order to ensure the strength of the drain plate and avoid deformation of the drain plate, the drain inclined plate 11, drain straight plate 12 and blanking plate 13 all include a grid structure in the middle and straight plates laid on the top and bottom surfaces of the grid structure, and the water filter holes are arranged on the straight plates. Water filter holes are provided on the top and bottom of the drain plate, and the grid structure in the middle of the drain plate ensures that the drain plate is structurally stable and does not deform during the process of supporting the slag, receiving impact, and cooperating with the roller belt 14 to extrude the slag.

[0025] like Figure 2 The roller belt 14 is arranged just above the unloading plate 13, and the rotation direction of the side of the roller belt 14 opposite to the unloading plate 13 is the same as the flow direction of the material on the unloading plate 13, and the spacing between the rotating roller of the roller belt 14 near the material unloading end and the unloading plate 13 is smaller than the spacing between the rotating roller at the other end and the unloading plate 13.

[0026] As the slag moves to the bottom of the roller belt 14 and continues to move, the rotation of the roller belt 14 can push the slag to a certain extent. During the movement, the slag is squeezed by the roller belt and the blanking plate 13 due to the reduction of the gap, thereby squeezing out the water in the slag.

[0027] like Figure 2 As shown, in order to ensure that the roller belt 14 can effectively squeeze the slag, a support plate 16 is fixedly arranged in the vibration frame 1, and the support plate 16 is located on the inner side of the roller belt 14 and the bottom surface of the support plate 16 is in contact with the inner bottom surface of the roller belt 14. The support plate 16 ensures that the roller belt 14 rotates along the set line, thereby ensuring the quality of rolling.

[0028] like Figure 2 As shown, in order to ensure that the roller belt 14 effectively pushes the slag to move, the outer wall of the roller belt 14 is equidistantly arranged with pusher protrusions 15.

[0029] like Figure 1 and Figure 2 As shown, the vibration of the vibration frame 1 is realized. The cam structure is a vibration roller 9 which is horizontally rotatably arranged at the top of the vibration frame 1, and the cross section of the vibration roller 9 is a cam structure.

[0030] In addition, the roller belt 14 may also adopt a stainless steel chain plate structure to extend the service life of the roller belt 14 .
