[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Combination Figures 1 to 4 As shown, the utility model provides a zinc slag salvaging device in a zinc pot. Both the horizontal frame 1 and the vertical frame 2 are frame structures. The horizontal frame 1 is fixed above the zinc pot and serves as a supporting base for the entire salvaging device. The horizontal frame 1 is provided with a pair of horizontal slide rails, and the vertical frame 2 is fixed with a composite bearing 9. The vertical frame 2 is slidably mounted on the slide rails of the horizontal frame 1 through the composite bearing 9. The vertical frame 2 is controlled to move along the horizontal frame 1 through a horizontal drive assembly 3. The vertical frame 2 provides guidance and support for the slag scooping mechanism 4, and has four vertical slide rails thereon. The slag scooping mechanism 4 is fixed with a composite bearing 9. The slag scooping mechanism 4 is slidably mounted on the slide rails of the vertical frame 2 through the composite bearing 9. The slag scooping mechanism 4 is controlled to move along the vertical frame 2 through a vertical drive assembly 5.

[0047] Recombination Figure 5 and Figure 6As shown, the horizontal drive assembly 3 is installed on the horizontal frame 1, including horizontal drive shafts 32 rotatably installed at both ends of the horizontal frame 1. The two horizontal drive shafts 32 are parallel and opposite to each other, and sprockets are fixed at both ends of the two horizontal drive shafts 32, and a horizontal drive chain 33 is connected between the opposite sprockets. A horizontal drive motor 31 is fixed at one end of the horizontal frame 1, and the horizontal drive motor 31 drives one of the horizontal drive shafts 32 through a transmission chain and a sprocket, and then drives two horizontal drive chains 33. The side of the vertical frame 2 is fixedly connected to the corresponding horizontal drive chain 33, and when the horizontal drive chain 33 rotates, it can drive the vertical frame 2 to move along the horizontal frame 1. A row of position sensors 34 arranged along the horizontal drive chain 33 are fixed on the horizontal frame 1, which are used to monitor the position of the vertical frame 2 and the slag scooping mechanism 4.

[0048] Recombination Figure 7 and Figure 8 As shown, a limit assembly 8 is installed on the vertical frame 2 and the horizontal frame 1 to limit the movement range of the vertical frame 2 on the horizontal frame 1. The limit assembly 8 includes a left limit block 81 and a right limit block 82 fixed at both ends of the horizontal frame 1. A fixed limit pin 84 cooperating with the right limit block 82 is fixed on one side of the vertical frame 2. The fixed limit pin 84 cooperates with the right limit block 82 to limit the right movement of the vertical frame 2. A movable limit pin 83 cooperating with the left limit block 81 is fixed on the other side of the vertical frame 2. The movable limit pin 83 cooperates with the left limit block 81 to limit the left movement of the vertical frame 2.

[0049] The state of the movable limit pin 83 is controllable. The movable limit pin 83 is slidably mounted on the vertical frame 2, and one end of the movable limit pin 83 is connected to a limit cylinder 831; the state of the movable limit pin 83 is controlled by the extension and retraction of the limit cylinder 831;

[0050] When the movable limit pin 83 is in the first state, the movable limit pin 83 extends, and the movable limit pin 83 is opposite to the left limit block 81 in the moving direction of the vertical frame 2, limiting the leftward movement of the vertical frame 2; the fixed limit pin 84 cooperates with the rightward movement restriction of the vertical frame 2, and limits the vertical frame 2 and the slag scooping mechanism 4 to perform slag scooping operations within the set operating range to prevent the zinc pot from being damaged;

[0051] When the movable limit pin 83 is in the second state, the movable limit pin 83 retracts, and the movable limit pin 83 and the left limit block 81 are no longer opposite to each other in the moving direction of the vertical frame 2, and no longer restrict the left movement of the vertical frame 2; at this time, the vertical frame 2 together with the slag scooping mechanism 4 moves to the left end of the horizontal frame 1 for slag dumping operation.

[0052] Combination Figures 1 to 4 ,as well as Figure 7 and Figure 8As shown, the vertical drive assembly 5 is installed on the vertical frame 2, including mutually parallel lifting drive shafts 52 rotatably installed at the upper and lower ends of the vertical frame 2, and a lifting motor 51 for driving the lifting drive shafts 52 at the upper end is fixed at the upper end of the vertical frame 2. A lifting chain 53 is connected between the two lifting drive shafts 52, and the slag scooping mechanism 4 is fixedly connected to the lifting chain 53. The lifting motor 51 drives the lifting drive shaft 52 and the lifting chain 53 to rotate, and then the lifting chain 53 drags the slag scooping mechanism 4 to move up and down.

[0053] Combination Figures 1 to 4 ,as well as Fig. 9 and Fig.10 As shown, the slag scooping mechanism 4 includes a main frame 44, on which a composite bearing 9 is fixed. The main shaft 41 is fixed to the lower side of the main frame 44, and the lower end of the main shaft 41 is hinged with a left slag bucket 42 and a right slag bucket 43. The opening and closing drive assembly 6 is installed on the main frame 44, including an opening and closing cylinder 61 fixed on the main frame 44, and the movable end of the opening and closing cylinder 61 is hinged with a pull rod 62, and the other end of the pull rod 62 is hinged with a rocker 63, and the rocker 63 is fixedly connected to the left slag bucket 42 and the right slag bucket 43 on the corresponding side.

[0054] The opening and closing cylinders 61 on both sides can independently control the status of the left slag bucket 42 and the right slag bucket 43. Fig.11 As shown, the left slag bucket 42 and the right slag bucket 43 have three working states when they are in operation. The left slag bucket 42 and the right slag bucket 43 can cooperate with each other to complete the slag scooping operation, or they can complete the slag scraping operation individually. Fig.11 When the amount of zinc slag is large, the first state a is adopted to directly grab it. When the amount of zinc slag is small, the second state b and the third state c can be adopted to scrape the slag first and then grab it, which improves the operation efficiency.

[0055] In this embodiment, the horizontal driving motor 31 , the position sensor 34 , the limit cylinder 831 , the lifting motor 51 and the opening and closing cylinder 61 are all controlled by the controller 7 .

[0056] When using,

[0057] The horizontal driving motor 31 drives the horizontal driving chain 33, and the horizontal driving chain 33 drags the vertical frame 2 and the slag scooping mechanism 4 to move horizontally above the zinc pot; the lifting motor 51 drives the lifting chain 53, and the lifting chain 53 drags the slag scooping mechanism 4 to move up and down above the zinc pot; finally, the opening and closing cylinder 61 controls the opening and closing of the left slag bucket 42 and the right slag bucket 43 through the pull rod 62, so that the slag bucket can realize the slag grabbing operation in the entire zinc pot.

[0058] After the slag scooping mechanism 4 enters the operating range, the movable limit pin 83 in the limit assembly 8 extends out, and the slag scooping mechanism 4 can only move within the limited operating range, avoiding pot collision accidents caused by equipment or sensor failure. When the slag scooping mechanism 4 needs to move out of the slag scooping operating range for slag dumping or non-slag scooping operations, the movable limit pin 83 retracts to avoid affecting the operation of the main production line.

[0059] The utility model provides a zinc slag salvaging device in a zinc pot, which can realize the automation of slag salvaging. The operating personnel only need to operate by remote control, which not only greatly improves the working environment of the on-site workers, but also improves the working efficiency, shortens the production line downtime, and improves the production line efficiency.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
