Problems solved by technology

[0005] Regarding the related technologies mentioned above, the inventor believes that since the raw material slurry contains both magnetic materials (metallic nickel) and non-magnetic materials (alumina), after the magnetic materials are adsorbed on the eccentric cylinder, there may be some non-magnetic materials It is squeezed between the magnetic material and the eccentric cylinder; when the magnetic material rotates with the eccentric cylinder, the magnetic material may fall off in advance, so the magnetic material may not fall into the high magnetic material tank, thereby reducing the recovery rate of the magnetic material

Abstract

The invention relates to a wet-process magnetic separator and a waste catalyst wet-process recovery system, and relates to the technical field of catalyst recovery. A permanent magnet cylinder is fixedly connected to the rack, the field intensity of the permanent magnet cylinder is gradually increased from bottom to top, and a notch is formed in the uppermost end of the permanent magnet cylinder and is formed in the axial direction of the permanent magnet cylinder; an eccentric cylinder is arranged on the rack in a penetrating manner, the eccentric cylinder is arranged in the permanent magnet cylinder in a penetrating manner, and the axis of the eccentric cylinder deviates towards the upper side of the permanent magnet cylinder; and the rack is further provided with a driving mechanism used for driving the eccentric cylinder to rotate. A collecting mechanism is further arranged on the machine frame and comprises a hopper arranged in the eccentric cylinder in a penetrating mode. According to the invention, the magnetic material is not easy to fall off from the eccentric cylinder, so that the recovery rate of the magnetic material is improved.

Description

technical field [0001] The invention relates to the field of catalyst recovery, in particular to a wet magnetic separator and a waste catalyst wet recovery system. Background technique [0002] In addition to being used in the production process of products, hydrogenation catalysts are also widely used in the refining process of raw materials and products. Hydrogenation catalysts include selective hydrogenation catalysts, non-selective hydrogenation catalysts, and hydrogenolysis catalysts. When cracking petroleum hydrocarbons into ethylene, propylene, etc. as raw materials for polymerization, it must first undergo selective hydrogenation to remove trace impurities such as alkynes, dienes, carbon monoxide, carbon dioxide, and oxygen without loss of alkenes. At this time, selective hydrogenation is required. Hydrogen catalysts, selective hydrogenation catalysts are generally nickel supported on alumina. Once the catalyst containing nickel is poisoned and fails, the catalyst ...
