Description

Technical Field

[0001] The utility model relates to the field of lead-zinc ore recovery, in particular to a lead-zinc ore recovery device. Background Art

[0002] Lead-zinc ore is an ore containing lead and zinc, usually in the form of lead-zinc sulfide ore. Lead-zinc ore is an important metal ore, widely used in metallurgy, construction, electronics and other fields. Lead-zinc ore often contains a certain amount of copper, so copper recovery is to maximize the use of resources and improve economic benefits. Most of the existing copper recovery devices for lead-zinc ore use a stirring mechanism to stir and mix with the flotation agent to adsorb copper ore and flotation agent to form foam flotation products, and then recover copper ore through separation and concentration steps. However, the existing lead-zinc ore recovery device cannot fully mix the lead-zinc frame raw materials and flotation agents, and the recovery efficiency is low, which urgently needs to be improved. Utility Model Content

[0003] The utility model aims to provide a lead-zinc ore recovery device, which is used to solve the problem that the existing lead-zinc ore recovery device cannot fully mix the lead-zinc frame raw material and the flotation agent.

[0004] In order to solve the above problems, the utility model provides a lead-zinc ore recovery device, including a box body and a box cover, a first central tube rotatably provided in the box body, a second central tube with an opposite rotation direction can be sleeved in the first central tube, first stirring rods are symmetrically fixed on both sides of the first central tube, second stirring rods are symmetrically fixed on both sides of the second central tube, a filter screen that can move up and down is provided in the box body, and a traction rope for synchronously driving the filter screen to move up and down is passed through the second central tube.

[0005] The lead-zinc ore recovery device provided by the utility model also has the following technical features:

[0006] Furthermore, a first driving assembly for driving the first center tube and the second center tube to rotate is installed on the top of the box cover, and the first driving assembly includes a bracket, a motor fixed on the bracket, a first bevel gear fixedly connected to the output shaft of the motor, a second bevel gear and a third bevel gear meshing with the first bevel gear, the second bevel gear is fixedly connected coaxially with the second center tube, and the third bevel gear is fixedly connected coaxially with the first center tube.

[0007] Further, a traction rod is slidably provided on the bracket. A first compression spring is provided between the traction rod and the bracket. The first compression spring is sleeved on the traction rod. A first magnetic block is fixedly provided at the bottom end of the traction rod. A driving disk is fixedly provided on the output shaft of the motor. Second magnetic blocks with opposite magnetic poles are spaced on the side wall of the driving disk. One end of the traction rope is fixedly connected to the filter screen, and the other end of the traction rope is fixed to one side of the first magnetic block.

[0008] Further, a limiting block is fixedly provided in the box body, and a second compression spring is fixedly provided between the bottom wall of the filter screen and the limiting block.

[0009] Further, a drain pipe is provided below the side wall of the box body.

[0010] Further, a brush that abuts against the inner wall of the box body is fixedly provided on one side of the first stirring rod.

[0011] The utility model has the following beneficial effects: The first stirring rod can be driven to rotate through the first central pipe, and the second stirring rod can be driven to rotate through the second central pipe. Since the rotation directions of the first central pipe and the second central pipe are opposite, the first stirring rod and the second stirring rod rotate reversely, improving the mixing degree of the lead-zinc ore and the flotation agent. At the same time, the filter screen can be driven to shake up and down through the traction rope, preventing the filter screen from being blocked. Description of the Drawings
