[0033] Working principle: The automatic collection and cleaning device is used in conjunction with the receiving bucket on the water seal tank of the heating furnace. Here, the track 1 corresponds to the slag discharge port at the bottom of multiple receiving buckets. When in use, the track 1 is laid on the ground to facilitate the autonomous transportation of the electric collection vehicle 2, and no personnel are required to push it to the bottom position of the receiving bucket. Here, the cooperation between the electric collection vehicle 2 and the track 1 can greatly save labor costs, and the operation is convenient and fast, and the work efficiency is high. First, the electric collection vehicle 2 moves autonomously on the track 1, and can be moved to the bottom of the receiving bucket so that the top of the feed inner tube 5 is in a straight line with the slag discharge port at the bottom of the receiving bucket. When the top of the feed inner tube 5 is in a straight line with the slag discharge port at the bottom of the receiving bucket, then The two mounting plates 7 and the inner feeding tube 5 are driven upward by the two electric push rods 8, so that the top end of the inner feeding tube 5 can be in contact with and communicated with the slag discharge port at the bottom end of the receiving bucket. When the top end of the inner feeding tube 5 is connected with the slag discharge port at the bottom end of the receiving bucket, the slag discharge port at the bottom end of the receiving bucket is opened first, and then the two driving motors 10 are started. When the two driving motors 10 are started, the two screw rods 11 are driven to rotate. When the two screw rods 11 rotate, the threaded connection between the screw rod 11 and the nut 12 and the sliding limit between the slider 13 and the slide groove 14 will drive the two nuts 12 to move away from each other. When the two nuts 12 move away from each other, the two blocks 15 will be driven to move away from each other. When the two blocks 15 move away from each other, they will drive the two The slide bar 17, the two slide tubes 16 and the two sealing plates 22 move away from each other. When the two slide tubes 16 move away from each other, the two return springs 20 are compressed. Then, when the two slide bars 17 move away from each other until they come into contact with the two unlocking rods 21, the two drive motors 10 are turned off. At the same time, when the two sealing plates 22 move away from each other, the discharge channel of the inner feed tube 5 can be opened and the iron oxide waste slag inside the receiving hopper can be introduced into the interior of the electric collection vehicle 2. Then, when the iron oxide waste slag inside the receiving hopper is discharged, the transmission between the drive motor 10 and the two slide bars 17 can drive the two slide bars 17 to continue to move away from each other and squeeze the two slide bars 17 through the two unlocking rods 21, so that the two slide bars 17 move upward. When the two sealing plates 22 are close to each other and in contact with each other, the two sealing plates 22 can be used to close the discharge channel of the inner feeding tube 5. When the channel of the inner feeding tube 5 is closed, the two electric push rods 8 drive the inner feeding tube 5 to disengage and reset the slag discharge port at the bottom of the receiving hopper. Here, the same structure and operation as above can be used to collect and clean the iron oxide waste slag inside the multiple receiving hoppers. This method is convenient to operate and saves time and effort.It replaces manual cleaning of iron oxide, greatly reduces workers' workload and labor intensity, avoids environmental pollution, and avoids safety risks in gas area operations.
