Abstract
The utility model belongs to a permanent-magnet separator which is mainly used to remove iron and various magnetic materials in grinding industry and is suitable for dry magnetic separation in other industries. The permanent-magnet separator is mainly characterized in that single primary roller with low intensity magnetic field made of permanent magnetic materials and double medium rollers with medium intensity magnetic field are combined to work continuously. The permanent-magnet separator overcomes the defect of magnetic separation with single machine. Zero magnetic zone exists in both the low intensity magnetic field and the medium intensity magnetic field. Working gap and magnetic field strength can be adjusted within limits. The permanent-magnet separator has the functions of an existing magnetic separator with low intensity magnetic field and a magnetic separator with medium intensity magnetic field. The medium magnetic field intensity of the permanent-magnet separator reaches 0.8T (8000GS) which is higher than that of any medium magnet separator.
Description
The utility model belongs to the equipment of magnetic separation aspect.
The permanent magnetism twin-stage three roller dry-type magnetic extractors that the utility model proposes are mainly used in dry method removal iron and various magnetic thing thereof in the Abrasive Industry, also can be used for refractory material, the dry magnetic separation of industries such as glassware, ceramic, flour processing, pharmacy.But the complete machine separate unit uses, and also can cooperate intensity magnetic separator to use jointly.
Background of the present utility model is: the dry-type magnetic extractor of Abrasive Industry use at present mainly contains two kinds, and a kind of is electromagnetism, and a kind of is permanent magnetism, no matter but the sort of magnetic separator all is a single-stage.Have two major defects like this, the disposable magnetic separation weak effect of the first if want magnetic separation effective, or selects multipass with separate unit, or adopts many magnetic separator connection in series-parallel to connect use.Multipurpose device is used feed mechanism more as a result, and complicated operation is expanded investment, and increases cost; It two is can not continuous operation, has increased working strength of workers, moreover has increased the magnetic material content in the material owing to repeat material loading; It because of the output of equipment own does not match, causes waste equipment, inefficiency three if adopt many magnetic separators.
The utility model purpose is the shortcoming at above-mentioned prior art, and provides a kind of low-intensity magnetic field, and two magnetic separators in middle magnetic field are assembled into one and magnetic separator that can continuous operation.Advantages such as it has simple in structure, and is with low cost, easy to operate, energy-efficient.
Below in conjunction with accompanying drawing its operation principle and structure are further described.
Figure one is the structure and the operation principle schematic diagram of utility model.The explanation of accompanying drawing drawing:
1-vibrating feed motor; The 2-vibrating bunker;
The 3-flow material plate; The outer roller of 4-primary magnetic roller;
The 5-ferromagnetism thing plate that connects material; The 6-ferromagnetism thing groove that connects material;
The weak magnetic thing of the 7-groove that connects material; The 8-casing;
The 9-reductor; The 10-driving motor;
The 11-mine-carrying groove; The fan-shaped magnetic pole of 12-;
Utmost point magnetic roller among the 13-; The 14-tripper;
15-discharging brush; The fan-shaped magnetic pole of 16-;
The 17-eccentric wheel; The 18-reductor;
Charging gear: it is made up of vibrating motor 1, reductor 18, eccentric wheel 17, vibrating bunker 2.
The magnetic roller segment: it is made up of an one-level magnetic roller and two two utmost point magnetic rollers.Each magnetic roller all is made up of outer roller 4 and fan-shaped magnetic pole 16,12, and magnetic pole is contained on the axle by adjusting rod, and axle is fixed on the support motionless.Magnetic pole and outer roller spacing can be regulated from changing its size by adjusting rod in magnetic field.The useful resin of axial direction and the quartz sand potting material of filling radially between magnetic pole.And each magnetic pole has all adopted preservative treatment.Three magnetic rollers are formed secondary, and one of them magnetic roller is formed elementary (low-intensity magnetic field level).Two remaining magnetic rollers are formed middle rank (middle magnetic field levels).Two-stage three rollers fit together can continuous operation.And every grade all has zero magnetic region.Working clearance and magnetic field intensity are adjustable within the specific limits.
The discharging part: it by high-strength elastic filament, wood spool, and belt pulley form.During the brush wheel wearing and tearing, can regulate distance between brush wheel and roller, when thorough wearing and tearing, can reuse by changing wood spool by kidney slot.
Transmission system: form by motor 10 reductors, 9 cone pulleys and V belt.Regulate the V-belt and can change magnetic roller rotating speed in the position of cone pulley.
The course of work and principle are as follows: vibrating motor 1 drives reductor 18, drives eccentric wheel 17 vibrations by reductor 18 again, and eccentric wheel drives hopper 2 vibrations.The material that process is vibrated is fallen by flow material plate 3 and is carried out primary election on the primary magnetic roller.The ferromagnetism thing is mainly removed in primary election.Material after the primary election is fallen on the intermediate magnetic roller through tripper 14, enters the further magnetic separation in constituency, intermediate magnetic field.Material in the process after the choosing enters mine-carrying groove 11.Weak magnetic thing then enters in the groove 7 that connects material.The ferromagnetism thing of just selecting is in the plate 5 that connects material flows to the groove 6 that connects material.When on the elementary tube ferromagnetism thing that does not come off being arranged, can be forced by discharging brush wheel 15 to come off.Whole magnetic separation process is all carried out in gas-tight silo, and dust seldom.
The utlity model has following advantage: at first we have adopted the characteristics that two-stage three rollers combine, and it is equivalent to original two magnetic separators in weak, middle magnetic field.And the two-stage magnetic field intensity is all than general similar magnetic separator field intensity height.Our its primary magnetic field intensity of utility model is at 0.2T～0.3T.The middle rank magnetic field intensity is at 0.7T～0.9T.It two is that two-stage combines can continuous operation.Only need a cover material loading mechanism, and select one time effect to select four times, five times effective than original unit.Promptly alleviate workman's manual labor, reduced cost again.It three is two-stage output coupling production efficiency height.It four is that our two-stage has all adopted ferrite and rare-earth permanent magnet to do magnetic pole, and it not only can save a large amount of electric energy and electrical equipment original paper, and gives and use and maintenance brings many convenience.The two-stage cost only is equivalent to original one three roller low-intensity (magnetic) separator cost, so can save half investment.
