Description

Technical Field

[0001] This utility model relates to aluminum ash slag conveying technology, specifically to an aluminum ash slag conveying device with self-cleaning function. Background Technology

[0002] Aluminum slag is a slag containing impure mixed metals produced during aluminum smelting, but it still contains a certain amount of aluminum. Some aluminum can be separated and refined. During the processing of aluminum slag, it needs to be crushed and then transported by conveying equipment.

[0003] Currently, a common type of conveying equipment for aluminum ash slag is the screw conveyor, which has a U-shaped structure and an internal spiral auger. The central shaft drives the spiral auger to rotate and transport the aluminum ash slag poured into it. However, after conveying, a significant amount of aluminum ash usually adheres to the spiral auger. Common cleaning methods include dismantling the screw conveyor and removing the spiral auger for cleaning, or using a blower at one of the feed inlets to blow air through the discharge outlet to remove the ash adhering to the spiral auger. The latter method is more convenient, but because the blower's airflow direction is fixed, aluminum ash facing away from the airflow direction is more difficult to detach from the spiral auger than ash facing the airflow direction, thus limiting the effectiveness of this cleaning method. Therefore, we propose a self-cleaning aluminum ash slag conveying device to solve the aforementioned problems. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-4 As shown, a self-cleaning aluminum ash conveying device includes a screw conveyor 1, a top cover 2 on the screw conveyor 1, partition grooves 3 evenly spaced along the length direction on the top cover 2, and air holes 4 on the front and rear sides of the screw conveyor 1 respectively, with each pair of adjacent air holes 4 forming a group, and several groups are arranged along the length direction of the screw conveyor 1. When not in use, the partition grooves 3 can be sealed by pressing in rubber sealing gaskets. When it is necessary to self-clean the screw conveyor 1, all the sealing gaskets pressed in on the top are removed, and then the drive structure is put into operation.

[0025] The movable components are symmetrically arranged on the front and rear sides of the screw conveyor 1. The movable components are equipped with movable plates 5. Connecting plates 6 are fixedly connected to the left and right sides of the movable plates 5 respectively. Air pipe connection ends 7 are fixedly provided on the front and rear sides of the connecting plates 6 respectively. The movable plates 5 slide on both sides of the screw conveyor 1. The connecting plates 6 are used to fix the air pipe connection ends 7. When the air pipe connection end 7 is connected to one of the air holes 4, air can be vented or vented in the screw conveyor 1 through the air hole 4. It should be noted that for the four air pipe connection ends 7, one end of the two air pipe connection ends 7 on the same side is connected to the exhaust pipe and the air inlet pipe respectively. The air inlet pipe is connected to the fan. In addition, the air inlet pipes on different sides are arranged on opposite sides to avoid the two coaxial and opposite air inlet pipes venting each other and causing conflict. In this way, the aluminum ash adhering to the surface of the screw blades in the screw conveyor 1 can be blown away from the blades and moved out through the exhaust pipe through the two air inlet pipes in two directions.

[0026] The lifting assembly is connected to the moving assembly. A gantry frame 10 is installed inside the lifting assembly. An electric cylinder is fixed on the top of the gantry frame 10. The output end of the electric cylinder is connected to the partition frame 8. The electric cylinder is used to drive the partition frame 8 to lift. The partition frame 8 is installed below the gantry frame 10. A push plate 9 is fixedly connected to the four corners of the top of the partition frame 8. The lifting assembly includes racks fixed on the front and rear sides of the screw conveyor 1. A motor is fixed on the far side of one of the moving plates 5. A gear is fixed on the output end of the motor. The gear meshes with the adjacent rack. The gear and rack meshing drives the moving plate 5 to move on the side of the screw conveyor 1. After self-cleaning at one position, the device is moved to the next position to continue self-cleaning inside the screw conveyor 1.

[0027] A connecting component is provided, and several connecting components are provided along the length direction of the screw conveyor 1. A telescopic tube 11 is provided inside the connecting component. The telescopic tube 11 is coaxial with a single adjacent air hole 4. One end of the telescopic tube 11 is integrally formed with a flange. The connecting component includes a fixed tube 20 fixed to the side wall of the screw conveyor 1. The telescopic tube 11 is slidably connected to the adjacent fixed tube 20. A third spring 21 is sleeved on the outside of the fixed tube 20. One end of the third spring 21 abuts against one side of the adjacent flange. The flange is used to limit the third spring 21. When one end of the telescopic tube 11 is not blocked, it will pop out from the fixed tube 20 under the action of the third spring 21, so that it can be connected to the air pipe connection end 7.

[0028] The valve opening assembly includes bending frames 12 that are slidably disposed at the front and rear ends of the gantry frame 10 and are symmetrically distributed on the left and right. The bottom left and right sides of the front and rear ends of the gantry frame 10 are integrally formed with protrusions 13. A first spring 14 is fixed between the protrusions 13 and the bottom ends of the adjacent bending frames 12. The bending frames 12 are used to move down under the action of the lower push plate 9 to press the valve closing frame 16 down, thereby facilitating the extension tube 11 to pop out and connect with the air pipe connection end 7. The first spring 14 is used to reset the bending frames 12 when they are not under pressure, and further reset the valve closing frame 16, making it easier to retract the extension tube 11.

[0029] A valve closing assembly is provided on both the front and rear sides of the screw conveyor 1, and several valve closing assemblies are arranged along the length of the screw conveyor 1. Each valve closing assembly includes a base plate 15 fixed to the screw conveyor 1. A valve closing frame 16 is slidably connected to the side wall of the screw conveyor 1 on the base plate 15. A second spring 17 is provided between the valve closing frame 16 and the adjacent base plate 15. The valve closing frame 16 includes a bent portion 18 that abuts against an adjacent bending frame 12. A guide slope 19 is provided on the valve closing frame 16. The valve has a valve hole. The guide slope 19 on the valve closing frame 16 is used to provide a certain distance for the telescopic tube 11 to move forward when the valve closing frame 16 descends. At the same time, the valve closing frame 16 is still clamped between the telescopic tube 11 and the air pipe connection end 7. This allows the telescopic tube 11 to be pushed back to the end away from the air pipe connection end 7 by the guide slope 19 when the valve closing frame 16 is reset upward. The bending part 18 is used to cooperate with the bending frame 12 to facilitate the valve closing frame 16 to be driven open by the bending frame 12, which facilitates the operation of opening and closing the valve.

[0030] In this embodiment, both ends of the bottom of the partition frame 8 are set as arcs, and arc grooves are opened on the left and right sides of the partition frame 8. The arc grooves are easy to insert into the main shaft of the screw conveyor 1. Secondly, before self-cleaning, the main shaft needs to be rotated to a specific angle so that the spiral blades at the location where the partition groove 3 is opened are mostly below the main shaft. This allows the partition frame 8 with the arc groove to work with it to temporarily block the sides of the self-cleaning area as much as possible, preventing the blown aluminum dust from scattering from the sides and staying in the screw conveyor 1 again.

[0031] In the specific implementation of this utility model: First, remove all the rubber strips of the sealing partition groove 3, and adjust the main shaft inside the screw conveyor 1 to rotate until the screw blades are in a suitable position. Then, connect the four air pipe connection ends 7 to the air inlet pipe and exhaust pipe respectively as required. Then, connect the device to an external power source, and control the motor in the moving component to work through the controller. The moving plate 5 is driven by the meshing of gears and racks to move the partition frame 8 to a suitable position through the gantry frame 10. Then, control the electric cylinder in the lifting component to work through the controller, so that it drives the partition frame 8 to descend, so that the two ends of the partition frame 8 are respectively inserted into the two adjacent partition grooves 3. When the partition frame 8 descends, it contacts and squeezes the bending frame 12 through the push plates 9 on both sides to make it descend. When the bending frame 12 descends, it compresses the first spring 14, and at the same time, its bottom contacts and squeezes the bent part 18 on the valve closing frame 16, so that the valve closing frame 16 descends. The restriction on the telescopic tube 11 is released through the guide inclined part 19, so that the telescopic tube 11 pops out under the elastic force of the third spring 21. The valve is always against one side of the valve frame 16 until the partition frame 8 is lowered to its lowest point. At this time, the valve hole is directly opposite the air pipe connection end 7. The external fan is started, and air is introduced through the air inlet pipe, allowing high-speed airflow to enter the screw conveyor 1 through the air hole 4. The aluminum dust attached to the screw blades is separated from the blades by the wind force and discharged outward from the air hole 4 on the opposite side, entering the exhaust pipe. After a fixed self-cleaning time in a certain area, the controller controls the output end of the electric cylinder to move in the opposite direction, driving the partition frame 8 to rise and move out of the partition groove 3. At the same time, the push plate 9 no longer squeezes the bending frame 12, allowing the bending frame 12 to reset under the action of the first spring 14. Meanwhile, the valve frame 16 moves upward under the action of the second spring 17, pushing the telescopic tube 11 to reset through the guide inclined part 19, recompressing the third spring 21. At the same time, the valve frame 16 seals the telescopic tube 11. Then, the controller controls the motor in the moving component to continue working, moving the component to the next area to continue the self-cleaning work in the next area of ​​the screw conveyor 1.
