Device for providing deep magnetic path spiral magnetic field to regulate and control movement of magnetic particle groups in ore pulp

Abstract

The invention discloses a device for providing a deep magnetic path spiral magnetic field to regulate and control movement of magnetic particle groups in ore pulp. The device comprises a frame. An upper support plate is fixedly arranged above the frame. The device further comprises an aluminum rotating ring, a rotating ring connecting plate, a rotating shaft, an inner support rod and a vessel support ring which are arranged above the upper support plate. Neodymium iron boron magnetic steel distributed from bottom to top in an annular spiral is embedded in the inner wall of the aluminum rotating ring. The rotating ring connecting plate is fixed to the bottom of the inner side of the aluminum rotating ring. An inner support rod is arranged in the rotating shaft. The inner support rod penetrates the center of the rotating ring connecting plate and extends into the aluminum rotating ring. The vessel support ring is fixed to the top end of the inner support rod. The lower part of the rotating shaft is rotationally connected with a bearing in the upper support plate. The lower part of the rotating shaft is connected with a driving device for drilling the rotating shaft to rotate. According to the device, loading of the secondary sports field of the magnetic particle groups is carried out on the stirred ore pulp, sufficient contact between the target mineral and a flocculating agent can be satisfied as far as possible, inclusion of gangue minerals can be avoided, the quality of a flocculating body can be improved, and a foundation can be laid for the next flotation.

Description

technical field [0001] The invention relates to the technical field of mineral processing process regulation and optimization, in particular to a device for providing a deep magnetic process helical magnetic field to regulate the movement of magnetic particle groups in ore pulp, in particular to a magnetic ore pulp stirring flocculation-flotation process for the initial stirring of the ore pulp A test device for secondary stirring of the magnetic particle group. Background technique [0002] The main function of flocculation in the flocculation-flotation process is to fully contact and settle the target minerals with the flocculant, laying the foundation for the next step of high-efficiency flotation, and in order to ensure the contact efficiency, stirring is very important; the existing stirring device can meet the requirements of ore pulp For the dispersion of medium particles, under the premise of optimizing the stirring speed, if the stirring is stopped and the flocculan...

Problems solved by technology

[0005] A device that can provide an external magnetic field and non-magnetic rotor agitation can realize the movement of magnetic particles in the pulp. The technical category disclosed in Chinese Patent Application No. 201310364769.7 belongs to the field of sewage treatment. The external magnetic field provides a magnetic field to drive the rotation of the magnetic catalyst to enhance the photocatalytic effect. The source of the rotating magnetic field is provided by the fixed magnet bar group driven by the rotating shaft. The rotating motion makes the magnetic catalyst evenly distributed in the pulp as far as possible, but the magnetic path cannot be guaranteed, that is, the magnetic catalyst does not work effectively within a certain distance range; and the magnetic field strength is also low. There is no guarantee, that is, the leading effect of the magnetic force provided by the magnetic bar structure on the magnetic particle group with initial velocity during the rotation process is poor
