Description

Technical Field

[0001] This application relates to the field of zinc smelting technology, and in particular to a zinc liquid recovery device for separating zinc slag. Background Technology

[0002] Zinc smelting produces a large amount of zinc dross, which contains numerous impurities such as silicates and alumina. To improve resource recovery, the zinc dross undergoes purification treatment to recover the zinc. The stirring method is a commonly used zinc recovery method. Its principle is based on the fact that zinc has a low density (approximately 6.6-7.1 g / cm³). 3 The density of impurities (such as silicates, alumina, etc., with a density of approximately 2.2-3.5 g / cm³) and impurities. 3 There are significant differences between them. By continuously stirring the zinc slag melt with a mechanical stirring device, the physical stratification of zinc liquid and impurities is promoted, so that zinc particles and zinc liquid settle to the bottom for easy recycling, while impurities are discharged through the ash discharge port.

[0003] To ensure the normal operation of the mixing device, regular cleaning is required. A cleaning door is typically installed at the bottom of the mixing device, which is normally closed and only opened during cleaning to facilitate the removal of ash and slag generated during cleaning. However, with increased use, the sealing effect of the cleaning door gradually deteriorates, causing a small amount of molten zinc to leak out from the gaps during mixing. While this small amount of leakage does not affect the normal operation of the mixing device, it represents a waste of resources. Utility Model Content

[0032] See Figure 1-5 The agitator 1 is used to separate zinc dross. Its structure is existing technology and will not be described in detail here. A cleaning door 11 is installed on the bottom side of the agitator 1. The cleaning door 11 is normally closed and is only opened when cleaning the agitator 1 to facilitate the discharge of the cleaned dross. To facilitate the collection of dross, a discharge chute 12 is also provided below the cleaning door 11. As the usage time increases, the sealing effect of the cleaning door 11 will deteriorate, causing a small amount of zinc liquid to leak from the gaps in the cleaning door 11 during zinc dross separation. Although this will not affect the normal use of the agitator 1, it will cause resource waste. Therefore, this application designs a zinc liquid recovery device for zinc dross separation, including:

[0033] A dust collection hood 2 is fixedly installed on the side of the mixer 1, covering the dust removal door 11. The top of the dust collection hood 2 is connected to a suction pipe 21. During dust removal, the suction pipe 21 draws in dust to treat the dust at the dust removal door 11, preventing dust spread and ensuring a clean working environment. A first opening 22 is provided on the side of the dust collection hood 2, allowing the ash hopper 3 to enter and collect the generated ash. A sealing plate 23 is rotatably installed at the first opening 22. During dust removal, the sealing plate 23 flips to close the first opening 22, reducing dust spread. Furthermore, to ensure the stable operation of the ash hopper 3, a railcar is used. Two parallel tracks 31 are laid on the factory floor, and the ash hopper 3 runs on the tracks 31. It should be noted that the dust collection hood 2, suction pipe 21, sealing plate 23, and ash hopper 3 are all existing technologies. Their specific structures and installation methods can be adjusted by those skilled in the art according to specific needs, and will not be elaborated upon here.

[0034] The guide channel 4 and the dust collection hood 2 are also provided with a second opening 24 on the side. A mounting rod 25 is welded horizontally at the second opening 24. One end of the guide channel 4 is rotatably connected to the mounting rod 25, and the other end is provided with a connecting ear 41. The connecting ear 41 is connected to the adjustment mechanism 6. The height of one end of the connecting ear 41 can be changed by adjusting the mechanism 6, so that the guide channel 4 is in an inclined state and the end near the connecting ear 41 is higher, which facilitates the guidance of zinc liquid.

[0035] The adjusting mechanism 6 includes a motor 61, a winding drum 63, and a rope 64. Two supports 62 are symmetrically fixed to the outside of the dust collection hood 2. The winding drum 63 is rotatably mounted between the two supports 62 and is fixed to the output shaft of the motor 61. The motor 61 can control the winding drum 63 to rotate forward and backward. One end of the rope 64 is fixed to the winding drum 63, and the other end passes through the dust collection hood 2 and is fixed to the connecting lug 41 of the guide channel 4. When the motor 61 rotates forward, the rope 64 gradually shortens and winds around the winding drum 63. At this time, the guide channel 4 rotates around the mounting rod 25 and closes, and the tilt angle increases. When the motor 61 rotates in reverse, the rope 64 gradually extends from the winding drum 63 and becomes longer. At this time, the guide channel 4 rotates around the mounting rod 25 and unfolds, and the tilt angle decreases.

[0036] See Figure 3The length of the mounting rod 25 is significantly greater than the width of the guide channel 4, typically 1.5-2 times. This design is to offset the positions of the guide channel 4 and the discharge channel 12 when the guide channel 4 is closed or opened, thus avoiding interference between them. Furthermore, since the guide channel 4 can slide on the mounting rod 25, a limiting block 26 is slidably connected to the mounting rod 25 to ensure the stability of the guide channel 4 during operation. The limiting block 26 has a first insertion hole 261, and the dust collection hood 2 has a second insertion hole 27 corresponding to the first insertion hole 261. When the first insertion hole 261 and the second insertion hole 27 are aligned, the limiting block 26 can be fixed by inserting a pin 28, thereby locking and fixing the guide channel 4. (See [reference]). Figure 4 At this time, the guide channel 4 is located directly below the discharge channel 12. After the zinc liquid leaks out from the ash removal door 11, it passes through the discharge channel 12 and the guide channel 4 in sequence, and then slides into the collection box 5 for unified collection.

[0037] See Figure 5 During the process of the guide channel 4 closing or opening, it is necessary to avoid collision between the guide channel 4 and the discharge channel 12. The lateral position of the guide channel 4 can be changed by adjusting the rod 7 so that the guide channel 4 and the discharge channel 12 are staggered. Specifically, a side ear 42 is provided on the guide channel 4. The adjusting rod 7 includes an operating rod 71 and a hook 72. The hook 72 is fixed to the end of the operating rod 71, and the size of the hook 72 matches the size of the through hole on the side ear 42. When in use, the worker holds the operating rod 71 and connects the hook 72 to the side ear 42. By pushing and pulling, the guide channel 4 can be moved horizontally on the mounting rod 25 so that the guide channel 4 is staggered from the discharge channel 12. Then, the motor 61 is controlled to rotate to retract and extend the rope 64, thereby controlling the closing or opening of the guide channel 4.

[0038] Furthermore, to prevent the adjustment rod 7 from being lost, two placement rings 73 are provided on the outside of the dust collection cover 2 along the vertical coaxial axis. After use, the adjustment rod 7 is inserted and placed in the two placement rings 73.

[0039] Based on the above embodiments, during dust removal, in order to prevent ash and dust from spreading from the second opening 24, an installation plate 29 is provided at the second opening 24. The installation plate 29 is provided with threaded holes 291. The fixing bolts 81 pass through the sealing cover 8 and are connected to the threaded holes 291 by threads, thereby fixing the sealing cover 8 and sealing the second opening 24 through the sealing cover 8.

[0040] Specific work process:

[0041] When the agitator 1 is working normally, the dust removal door 11 is closed. At this time, a small amount of zinc liquid will leak out, and the guide channel 4 needs to be unfolded. The process is as follows: first, the guide channel 4 is pulled by the adjusting rod 7 so that the position of the guide channel 4 is offset from the discharge channel 12. Then, the winding drum 63 is controlled by the motor 61 to gradually release the rope 64. At this time, the guide channel 4 rotates around the mounting rod 25 under the action of gravity and tends to be flat. When the height of the guide channel 4 is lower than the discharge channel 12, the motor 61 stops. The guide channel 4 is pushed below the discharge channel 12 by the adjusting rod 7 to wait for the overflow of zinc liquid.

[0042] When cleaning the agitator 1, the guide trough 4 is retracted, the cleaning door 11 is opened, and the ash slag is received by the ash hopper 3. The process is as follows: first, the guide trough 4 is pulled by the adjusting rod 7 to make the position of the guide trough 4 offset from the discharge chute 12. Then, the winding drum 63 is controlled by the motor 61 to gradually tighten the rope 64. At this time, the guide trough 4 rotates around the mounting rod 25 under the tension of the rope 64 and tends to be vertical. When the position of the guide trough 4 does not block the movement of the ash hopper 3, the motor 61 stops, and the ash hopper 3 is moved to below the discharge chute 12. Then, the cleaning door 11 is opened, and the sealing plate 23 is flipped to close the first opening 22. The sealing cover 8 is installed to close the second opening 24 to prevent dust from spreading. Finally, the ash slag is removed from the cleaning door 11 and falls into the ash hopper 3.

[0043] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
