[0003] When working in the fuming furnace, the staff will observe the flames inside the furnace and judge the smelting process based on experience. After the smelting cycle is over, the staff will open the valve to let the slag flow out from the slag discharge port into the water quenching tank for water cooling. Afterwards, the staff will remove the soot from the attached surface by airflow purging and collect it to a designated location for processing or recycling through the corresponding collection and conveying system.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Referring to Figures 1-3, one embodiment of this utility model provides an automatic slag discharge and ash removal device for sulfide volatilized tin slag in a fumigation furnace, applied to a reactor 1. A slag discharge box 2 is fixedly connected to the lower part of the reactor 1. A movable plate 3 is slidably connected through the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the movable plate 3, allowing the movable plate 3 to move vertically. A trapezoidal block 4 is slidably connected to the bottom end of the movable plate 3. The left side wall of the trapezoidal block 4 is elastically connected to the slag discharge box 2 via a movable spring 5. A weight block 6 is slidably connected to the upper surface of the trapezoidal block 4. When trapezoidal block 4 moves to the left, it will squeeze weight block 6, causing weight block 6 to move upward. The inner wall of slag discharge box 2 is equipped with a limit mechanism and an adjustment component. The limit mechanism includes a movable rod 7, on which a inclined block is provided. When weight block 6 squeezes the inclined block, the movable rod 7 moves backward. The inner side wall of the movable rod 7 is elastically connected to the slag discharge box 2 through a movable spring 8. The movable rod 7 passes through and slides on the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the movable rod 7, allowing the movable rod 7 to move back and forth.
[0033] Referring to Figures 2-4, the adjusting assembly includes an adjusting rod 10. The inner sidewall of the adjusting rod 10 is elastically connected to the slag discharge box 2 via a positioning spring 11. A connecting ring 9 is fixedly connected to the outer wall of the adjusting rod 10. A counterweight 12 is inserted into the outer wall of the adjusting rod 10. Two sets of protrusions are provided on the adjusting rod 10, with the upper protrusion being longer than the lower protrusion. Each protrusion has an inclined surface. Two sets of counterweights 12 are provided, each with a slot corresponding to one of the two sets of protrusions. The protrusions are initially inserted into the slots. The adjusting rod 10 passes through and slides on the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the adjusting rod 10, allowing the adjusting rod to slide through. The rod 10 can move back and forth. The connecting ring 9 is slidably connected to the outer wall of the movable rod 7. The movable rod 7 has a groove corresponding to the connecting ring 9. When the movable rod 7 moves backward, it will not affect the connecting ring 9. The counterweight 12 is slidably connected to the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the counterweight 12, allowing the counterweight 12 to move vertically. The inner side wall of the adjusting rod 10 is fixedly connected to one end of the positioning spring 11. The other end of the positioning spring 11 is fixedly connected to the inner wall of the rear end of the slag discharge box 2. When the adjusting rod 10 moves backward, the positioning spring 11 is compressed. When resetting, the elastic force of the positioning spring 11 is used to reset the adjusting rod 10.
[0034] Referring to Figures 1-3, the inner sidewall of the movable rod 7 is fixedly connected to one end of the movable spring 8, and the other end of the movable spring 8 is fixedly connected to the inner rear wall of the slag discharge box 2. When the movable rod 7 moves backward, the movable spring 8 is compressed. When resetting, the elastic force of the movable spring 8 carries the movable rod 7 back to its original position. The left sidewall of the trapezoidal block 4 is fixedly connected to one end of the movable spring 5, and the other end of the movable spring 5 is fixedly connected to the inner left wall of the slag discharge box 2. When the trapezoidal block 4 moves to the left, the movable spring 5 is compressed. When retracting and resetting, the trapezoidal block 4 is reset by the elastic force of the movable spring 5. The movable rod 7 is inserted into the inner wall of the weight block 6. The trapezoidal block 4 is slidably connected to the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the trapezoidal block 4, allowing the trapezoidal block 4 to move left and right. The weight block 6 is slidably connected to the inner wall of the slag discharge box 2. The slag discharge box 2 has a slot corresponding to the weight block 6, allowing the weight block 6 to move vertically. The top of the weight block 6 contacts the bottom of the counterweight block 12.
[0035] Working principle: During slag discharge, when the high-temperature molten slag falls onto the moving plate 3, and the slag on the moving plate 3 reaches a certain weight, the slag will squeeze the moving plate 3 downwards. The moving plate 3 will then squeeze the trapezoidal block 4, causing the trapezoidal block 4 to move to the left and compress the movable spring 5. At the same time, the trapezoidal block 4 will squeeze the weight block 6, causing the weight block 6 to move upwards. When the moving plate 3 moves downwards, an opening will appear on the slag discharge box 2, and the molten slag will flow out from the opening. Simultaneously, when the weight block 6 moves upwards, it will squeeze the movable rod 7, causing the movable rod 7 to move backwards and compress the movable spring 8. When the slot on the weight block 6 is aligned with the movable spring 8, the molten slag will flow out. When the inclined blocks on the moving rod 7 overlap, under the elastic force of the moving spring 8, the inclined blocks are inserted into the slot of the standard weight block 6, thus limiting the standard weight block 6. At this time, the opening remains open, and the molten slag will continue to flow out. When the opening needs to be closed, the hand moves the moving rod 7 backward. When the inclined blocks on the moving rod 7 separate from the slot on the standard weight block 6, the standard weight block 6 will move downward under its own weight. With the elastic force of the moving spring 5, the trapezoidal block 4 will move to the initial position. At this time, the trapezoidal block 4 will press the moving plate 3, causing the moving plate 3 to move upward and block the opening on the slag discharge box 2.
[0036] When the slag discharge rate needs to be changed, the adjusting rod 10 is moved backward by hand. At this time, the length of the adjusting rod 10 can be adjusted as needed. When the adjusting rod 10 moves backward, it will compress the positioning spring 11. When the protrusion on the adjusting rod 10 separates from the groove on the counterweight 12, the counterweight 12 will fall down and fit against the standard weight 6 under its own gravity. When the reactor 1 discharges slag, more molten slag is needed to compress the moving plate 3 to move downward. The downward movement of the moving plate 3 will compress the trapezoidal block 4, which will compress the standard weight 6 to move to the left. The standard weight 6 will move upward with the counterweight 12. The counterweight 12 and the standard weight 6 will compress the movable rod respectively. 7 and adjusting rod 10, movable rod 7 and adjusting rod 10 will be inserted into the slots of standard weight block 6 and counterweight block 12, keeping the slot of slag discharge box 2 open to discharge molten slag. When it is necessary to close the opening, move adjusting rod 10 backward by hand. Adjusting rod 10 will move backward with connecting ring 9. Connecting ring 9 will squeeze movable rod 7 to move backward. At this time, adjusting rod 10 and movable rod 7 will separate from the slots of standard weight block 6 and counterweight block 12 respectively. Standard weight block 6 and counterweight block 12 will move downward to squeeze trapezoidal block 4, so that trapezoidal block 4 squeezes moving plate 3 to move to the initial position and block the opening. At this time, movable rod 7 and adjusting rod 10 move to the initial position.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
