Abstract

The utility model discloses an internally driven magnetic separator. The internally driven magnetic separator is used for separating iron particle power in the cooling and cleaning liquid of a precision grinder, a bearing grinder, and a precision cleaning machine. The internally driven magnetic separator is mainly composed of a box body, a roller, a rubber press roller, and a scraping plate. The internally driven magnetic separator is mainly characterized in that a permanent magnetic synchronous low speed motor is arranged in the roller. An armature shaft and an inner ring of a speed change bearing are fixedly connected. An outer ring of the speed change bearing is connected with the roller by a connecting sleeve. The utility model has less abrasion, low noise, low temperature raise, high work efficiency, and long service life.

Description

The interior magnetic separator that drives

The utility model relates to a kind of magnetic force absorption, purifier of irony in separation machinery cooling fluid, the cleaning fluid of utilizing.

Magnetic separator is mainly used in precision grinder, bearing grinder, reaches the accurate Cress that cleans machine tool coolant (cutting fluid or emulsion).It is adsorbed on drum surface by magnetic pulley with the iron filings in the liquid, carries out Separation of Solid and Liquid.Use magnetic separator can reduce emery wheel correction number of times, prolong the service life of emery wheel and cooling fluid, reduce environmental pollution, improve the processing roughness and alleviate labor strength.Magnetic separator is precision grinder, machining transfer matic indispensable accessory.Traditional magnetic separator is the twin-stage worm gear structure of high speed ratio, and the major defect that this structure is brought is: 1. transmission efficiency is low, and power consumption is big.2. mechanical wear is serious, service life is short, because worm and gear is paid and is in high speed reducing ratio running status (being generally 1000: 1) during work, especially the worm screw rotating speed during first order worm and gear is paid is 3000r/mim, although therefore adopt the flooding system lubrication cooling, but mechanical wear is still very serious, and generally this device worm and gear working life of paying only is 2000 to 4000 hours.3. the mechanical movement noise is big, and heating is high, and is especially more obvious in the wearing and tearing middle and later periods.4. the flight-line maintenance cycle lacks, and the cost height is pressed day operation and calculated in 12 hours, and in about 1 year of the cycle that the general replacement worm and gear is paid, renewal cost accounts for about the 20-25% of full device.5. the motor temperature height easily produces electrical fault.

The purpose of this utility model provides a kind of simple in structure, the transmission efficiency height, and the few noise of wearing and tearing is little, and temperature rise is low, the magnetic separator of long service life.

The utility model comprises casing (5), the left and right sides of casing (5) is provided with left half axle (17) and right axle shaft (17 ') respectively, cylinder (1) is by bearing (16), (16 ') are supported on this left side, on the axle journal of right axle shaft, do the rotation of rolling, right axle shaft is a hollow shaft, its right-hand member is connected with the electric box of brush (10), cylinder (1) top is provided with rubber roller (2), scraper plate (6) is tangent with the periphery of cylinder (1), its principal character is: cylinder is provided with the permanent-magnet synchronous slowspeed machine in (1), the stator of this motor is made up of magnetic boots ring (12) that is fixed on cylinder (1) inwall and the permanent ring magnetic steel (11) that is embedded in the magnetic boots ring (12), the rotor of this motor is made up of with the armature shaft (18) of fixedlying connected with variable-speed bearing (8) inner ring armature (9), fixedly connected with the left end cap (14) of cylinder (1) through connecing cover (13) in the outer ring of variable-speed bearing (8), the lead of brushing electric box (10) is connected with armature (9) by the rotating shaft endoporus in the right axle shaft (17 ').

Effect of the present utility model is: 1. owing in the cylinder of the present utility model constant magnetism low-speed synchronous motor is set, its power rotating speed is little, associated mechanical, electrical installation is in the lower-speed state moves, therefore mechanical wear is few, noise is little, and it is low to generate heat, long service life.2. because magnet steel of the present utility model is connected with cylinder outer wall through the magnetic boots, and its external magnetic field is used to adsorb the irony powder, internal magnetic field acts on the coiling armature, become the permanent-magnet pole of low speed synchromotor, the permanent-magnet steel in the bidirectionally employing cylindrical shell, simple in structure, adsorbing separation is effective, the efficient height.3. be arranged in the drum owing to whole mechanical parts of the present utility model are concentrated, and adopt variable-speed bearing, volume is little, and is in light weight.

Accompanying drawing 1 is the utility model front view.

Accompanying drawing 2 is the left view of Fig. 1.

Accompanying drawing 3 is the utility model internal structure schematic diagram.

Just further describe the utility model below in conjunction with accompanying drawing and enforcement.

Referring to accompanying drawing 1,2.Casing (5) top is inlet; Cooling fluid is entered in the casing (5) by inlet, the bottom is provided with drain plug (4) and liquid outlet, energising back roll (1) rotates, because ring magnetic steel (11) external magnetic field effect, irony powder in the cooling fluid is adsorbed on cylinder (1) surface, the rubber roller (2) that is arranged on cylinder (1) top is discharged the extruding of the cooling fluid in the iron filings layer, iron filings go to the contact position with scraper plate (6), scraped by scraper plate (6), and enter along flute (7) and to deposit the bits box, the cooling fluid that flows out from liquid outlet can continue to use after debris removal.The elasticity at rubber roller (2) two ends is adjusted screw (3), (3 '), in order to regulate the pressure between rubber roller (2) and cylinder (1).

Referring to accompanying drawing 3, cylinder (1) is supported on by bearing (16), (16 ') on the axle journal of left half axle (17) and right axle shaft (17 '), magnetic boots ring (12) by about be bolted to the inwall of cylinder (1), ring magnetic steel (11) is embedded in the magnetic boots ring (12).The left end of armature shaft (18) is fastenedly connected by the inner ring of connecting key and variable-speed bearing (8), fixedlys connected with the left end cap (14) of cylinder (1) through connecing cover (13) in the outer ring of variable-speed bearing (8).Variable-speed bearing (8) be commercially available interior, in, the existing procucts of outer three coil structures, inner ring is input in the utility model, centre circle is fixed, the outer ring is output, uses as the Rolling push rod decelerator and the mechanical connecting device of speed ratio about 24: 1.(15) be the O RunddichtringO.
