Description

Technical Field

[0001] The utility model belongs to the technical field of slag fishing devices for zinc slag sedimentation tanks, and particularly relates to a slag fishing device for a zinc slag sedimentation tank. Background Art

[0002] The main function of a zinc slag sedimentation tank is to separate zinc slag solid particles from a zinc-containing solution to purify the solution and recover the zinc in it. Through a physical sedimentation process, the zinc slag settles to the bottom of the tank, thereby achieving solid-liquid separation. The fished zinc slag contains a certain amount of zinc and other valuable metals, which can be recycled through further smelting or chemical treatment. These slag materials can be used to manufacture zinc alloys, as desulfurizing agents for steelmaking, or in some cases, reused in the zinc production process after treatment. In addition, zinc slag may also be used in fields such as building materials and chemical raw materials.

[0003] In the prior art, the device for fishing zinc slag is a grab bucket. When grabbing materials, the grab bucket is moved above the sedimentation tank, and the grab bucket is opened during the lowering process and grabs the zinc slag when lifting at the bottom of the sedimentation tank to achieve the fishing of zinc slag in the sedimentation tank.

[0004] However, there are still some problems in the prior art. Due to the shape limitation of the grab bucket, some zinc slag at the bottom of the sedimentation tank cannot be grabbed by the grab bucket and remains at the bottom of the sedimentation tank wall, resulting in insufficient recovery of zinc slag. Content of the Utility Model

[0005] Aiming at solving the problems existing in the above prior art, the utility model provides a slag fishing device that can completely fish the zinc slag in the zinc slag sedimentation tank.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0007] A slag fishing device for a zinc slag sedimentation tank includes a fishing bucket, a control box, and a cable. The fishing bucket is hoisted below the control box through the cable. The upper end of the cable is connected to a winch inside the control box. A motor is installed inside the control box, and the power output end of the motor is connected to the power input end of the winch.

[0008] Furthermore, the fishing bucket includes a grab bucket, a flat plate, a pulley, a limiting plate, and a connecting rod. The grab bucket and the flat plate are hinged together, and a pulley is provided at the hinge. The pulley is connected to the cable to hoist the fishing bucket below the control box. The limiting plate is respectively connected to the grab bucket and the flat plate through the connecting rod, and the upper part of the limiting plate is connected to the control box through a limiting rope.

[0009] Furthermore, water drainage openings are provided below the grab bucket and the flat plate of the fishing bucket.

[0010] According to the above technical solution, the beneficial effects of the present utility model are as follows: One side of the salvage bucket adopted by the present utility model is designed as a flat plate type. When salvaging zinc slag at the bottom dead angle of the sedimentation tank wall, the flat plate side falls against the sedimentation tank wall and salvages the zinc slag at the bottom of the tank wall when rising, effectively solving the problem of zinc slag deposition at the bottom dead angle caused by the shape limitation of the grab bucket in the prior art. At the same time, the water drainage port at the bottom of the salvage bucket can reduce the disturbance to the water flow during the salvage process and avoid the zinc slag escaping with the disturbed water flow.

[0015] In order to more clearly illustrate the technical solution implemented by the present utility model, the present utility model will be described in detail below in conjunction with the drawings and embodiments.

[0016] A zinc slag sedimentation tank slag salvage device includes a salvage bucket 1, a control box 2 and a cable 3. The salvage bucket 1 is hoisted below the control box 2 through the cable 3. The upper end of the cable 3 is connected to the winch in the control box 2. A motor is installed inside the control box 2, and the power output end of the motor is connected to the power input end of the winch. The control box 2 is hoisted below the gantry crane of the sedimentation tank through the cable. The control box 2 and the salvage assembly connected to the control box 2 are moved up and down or the direction is adjusted through the traction system on the gantry crane. The salvage bucket 1 is connected to the control box 2 through the cable. The winch is driven by the motor to rotate, and the cable is controlled to be retracted and released to lift or lower the salvage bucket 1.

[0017] Furthermore, the salvage bucket 1 includes a grab bucket 11, a flat plate 12, a pulley 13, a limit plate 14, and a connecting rod 15. The grab bucket 11 and the flat plate 12 are hinged together, and a pulley 13 is provided at the hinge. The pulley 13 is connected to the cable 3, and the salvage bucket 1 is hoisted below the control box 2. The limit plate 14 is respectively connected to the grab bucket 11 and the flat plate 12 through the connecting rod 15, and the upper part of the limit plate 14 is connected to the control box 2 through a limit rope. When the cable 3 is lowered, the hinge between the grab bucket 11 and the flat plate 12 moves downward under the action of gravity, and the grab bucket 11 and the flat plate 12 are pulled open by a certain angle by the limit plate 14 and the connecting rod 15. When the cable 3 is retracted, the hinge is pulled up by the cable 3, and the grab bucket 11 and the flat plate 12 are closed to realize the slag salvage process.

[0018] Furthermore, drain openings are provided below the grab bucket 11 and the flat plate 12 of the salvage bucket 1. During the closing process, the drain openings allow water to pass through, avoiding excessive disturbance of the solution by the closed grab bucket 11 and flat plate 12 and causing zinc slag to escape.

[0019] According to the above embodiments of the present invention, the working process is as follows:

[0020] After the zinc slag in the sedimentation tank has settled, move the salvage bucket 1 above the sedimentation tank along the gantry crane guide rail, and control the up and down movement of the control box 2 through the traction of the gantry crane. When the control box 2 moves down to a suitable position, start the motor of the control box 2, rotate the winch to lower the cable 3 connected to the winch in the control box 2 to make the salvage bucket 1 descend. During the descent, the grab bucket 11 and the flat plate 12 open by a certain angle. After the salvage bucket 1 contacts the zinc slag at the bottom of the tank, retract the cable 3 to close the grab bucket 11 and the flat plate 12 to salvage the zinc slag. After salvaging the zinc slag, continue to lift the cable 3 to lift the salvage bucket 1 out of the water surface. When salvaging the dead corner at the bottom of the tank wall, lower one side of the flat plate 12 close to the tank wall, and the subsequent slag salvage process is the same as the above process.
