The utility model discloses a system is taken out in outside that a plurality of outer tubes and pump are constituteed, provides power through the ore pulp of pump in to the outer tube, increases the flow rate of cell body lower part ore pulp to avoid most ore pulp granule to pile up subsiding in the cell body lower part.
Description
Technical Field
The utility model belongs to the ore dressing field, concretely relates to half countercurrent magnetic separator.
Background
Magnetic separators are well known as magnetic separation equipment commonly used in mineral processing fields. The semi-countercurrent permanent magnetic drum magnetic separator can obtain high-quality iron ore concentrate, can obtain better recovery rate at the same time, and is widely applied to production practice. It mainly comprises three main parts, namely a cylinder 1, a magnetic system 2 and a box bottom 3 (a groove body), as shown in figure 1. The cylinder is formed by rolling and welding stainless steel plates with the thickness of 2-3 mm. The end cap of the cylinder is an aluminum casting and is connected with the cylinder by stainless steel screws. Stainless steel (copper) or aluminum is used as the cylinder body, because the materials are non-magnetic materials and have good magnetic permeability, the magnetic line of force can not form a magnetic short circuit with the cylinder body. The surface of the cylinder is also coated with a layer of wear-resistant rubber or a winding-layer thin copper wire as a protective layer, so that the cylinder surface is not worn. Meanwhile, the magnetic mineral particles are attached to the surface of the cylinder, the carrying effect of the cylinder on the magnetic mineral particles is enhanced, and the cylinder is driven to rotate by the motor. The magnetic system is a three-pole permanent magnetic system, and also has four poles or multiple poles. The polarities of the magnetic poles are alternately arranged along the rotating direction of the cylinder and are fixed during working. When the magnetic ore particles are attracted to the surface of the cylinder and rotate along with the cylinder, the magnetic stirring phenomenon is generated due to the alternate polarity, so that a part of non-magnetic ore particles mechanically mixed in the magnetic ore particles are removed, and the quality of a magnetic product can be improved. The ore pulp is easy to settle after being conveyed by the tank body, and the settled particles at the bottom of the tank body are easy to block the tank body and are not easy to clean.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a half countercurrent magnetic separator can avoid subsiding of granule in the cell body.
The specific technical scheme is as follows: a semi-countercurrent magnetic separator comprises a frame, a groove body with an ore feeding box, a cylinder, a magnetic system and a transmission control part; the magnetic system is a multi-pole permanent magnetic system, magnetic poles are arranged along the rotating direction of the cylinder, a plurality of outer pipes are arranged at the lower part of the tank body, a pump is arranged on each outer pipe, one end of each outer pipe is connected with the tank body close to the ore pulp inlet, and the other end of each outer pipe is connected with the tank body close to the ore pulp outlet.
Advantageous effects
The utility model provides power for the ore pulp in the outer pipe through the external pumping system consisting of a plurality of outer pipes and pumps, and increases the flowing speed of the ore pulp at the lower part of the tank body, thereby avoiding the sedimentation accumulation of most ore pulp particles at the lower part of the tank body; furthermore, because the outer pipe is arranged at the lower part of the tank body, particles at the bottom of the ore pulp are easy to convey through the outer pipe and the pump, and therefore sedimentation and accumulation of most ore pulp particles at the lower part of the tank body are avoided.
