Abstract

The utility model relates to a roller type magnetic selection device for recycling waste iron from flowing waste residue, essentially consisting of a motor, a roller, a scraper and a transmission belt; wherein, the roller is internally embedded with a magnet for absorbing the iron residue; the scraper and the transmission belt all pass through the roller, and the transmission belt is positioned under the scrapper so as to continuously scrape the iron residue onto the transmission belt. The utility model has high filtering efficiency and can work continuously, without necessity of discharging by stopping machine, thereby promising extremely high work efficiency.

Description

The drum-type magnetic plant

The utility model relates to a kind of drum-type magnetic plant that reclaims scrap iron from the iron-smelting furnace slag.

For a long time, the slag that iron-smelting furnace is discharged is taken as garbage disposal always and falls, owing to contain a large amount of scrap iron in the slag, causes unnecessary economic loss and waste.Retrieving publication number from China's " Gazette of Patent for Invention " is CN1068758A, and name is called the innovation and creation of " internal cylinder type magnetic separating method and equipment thereof ".This equipment mainly is made up of cylinder, magnetic system, motor and the groove that connects material, cylinder is a non-magnet material, and magnetic system is positioned at cylinder outer surface and near the below, the groove that connects material is installed in the cylinder, the driven by motor cylinder rotates, after waste material entered cylinder, ferromagnetic material was inhaled by magnetic force and is upwards rotated with cylinder, when going to the cylinder top, because ferromagnetic material away from magnetic is, magnetic force weakens, and ferromagnetic material in the groove that connects material, reaches the recovery purpose by gravity fall.Because the incipient stage mainly leans on magnetic system generation magnetic force to drive ferromagnetic material and upwards rotates, and when ferromagnetic material away from magnetic is, mainly moves upward by centrifugal force, leans on gravity fall at last in the groove that connects material.Because ferromagnetic material is not of uniform size, weight does not wait, and causes the fall time difference, so the scope in setting point is bigger, falls easily in the groove outside that connects material, and causes Lou choosing, and screening effeciency is not high; Owing to adopt the groove that connects material to collect ferromagnetic material, when the groove that connects material is filled, need to shut down discharging, be not suitable for the ferromagnetic material of continuous-flow is screened, so inefficiency.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of screening effeciency height is provided, and can carry out step sizing to the ferromagnetic material that flows and the drum-type magnetic plant that need not shut down.

For achieving the above object, the utility model drum-type magnetic plant, comprise cylinder, motor, decelerator, drum belt, scraper, integral support, platen, conveyer belt, it also comprises drum belt, scraper, integral support, platen, conveyer belt, cylinder is by inner core, urceolus and biside plate are connected as a single entity, side plate has a diameter and the corresponding circular hole of inner core external diameter, stud with magnet between inner core and the urceolus, magnet is axially-aligned along circumference, have between each row magnet at interval, inner core is a non-magnet material, hang on reducer output shaft the drum belt upper end, drum belt lower end pocket plays cylinder, and scraper edge and inner core top are pressed close to, and conveyer belt is arranged in cylinder scraper below.

In the such scheme, owing to stud with magnet in the cylinder, the scum of the cylinder of flowing through is adsorbed on the inner tube wall by magnetic force tightly; Because scraper is pressed close to the inner core roof, blocked the scum of coming with the cylinder rotation, determined the accurate position that scum falls; Because the magnet in the cylinder is axially-aligned along circumference, have between each row magnet at interval, inner core is a nonmagnetic substance.Therefore, after scraper blocked scum, cylinder continued rotation, scum and inner wall of rotary drum relatively move, and when the interval location between magnet went to the scum place, this place's magnetic force was very little, scum accurately falls on the conveyer belt by gravity, and cylinder is long more, rotating speed is high more, and screening effeciency is also high more.After adopting conveyer belt, the scum that screens continuously can be sent, and need do not shut down discharging, therefore, high efficiency.

Below in conjunction with accompanying drawing the utility model drum-type magnetic plant is described in further detail.

Fig. 1 is the front view of the utility model drum-type magnetic plant;

Fig. 2 is the left view of the utility model drum-type magnetic plant;

Fig. 3 is the cutaway view of drum-type magnetic plant shown in Figure 1 along the A-A line;

The utility model drum-type magnetic plant mainly is made up of cylinder 6, motor 2, decelerator 1, drum belt 8, scraper 4, integral support 5, platen 3, conveyer belt 7.Cylinder 6 is welded or is spirally connected by inner core 12, urceolus 13 and two annular side plate 9 and forms, side plate 9 center hole diameters are corresponding with inner core 12 external diameters, side plate 9 external diameters are greater than urceolus 13 external diameters, so that drum belt 8 is difficult for skidding off when work, stud with magnet 10 between inner core 12 and the urceolus 13, magnet 10 is axially-aligned along inner core 12 outer walls, and interval 11 is arranged between each row magnet 10, and inner core 12 is a non-magnet material.After arranging like this, 11 place's magnetic force are very little at interval in inner core 12 respective magnet.Integral support 5 is by front panel, rear board and connecting rod weld or are spirally connected and form, one diameter and the corresponding circular hole of cylinder internal diameter are arranged on front panel and the rear board, there is an opening position corresponding with its time surface roller 6 above the platen 3, so that drum belt 8 passes through, platen 3 is installed in above the integral support 5, motor 2, decelerator 1 is installed on the platen 3, hang on decelerator 1 output shaft drum belt 8 upper ends, opening and pocket that drum belt 8 lower ends are passed on the platen 3 play cylinder 6, cylinder is suspended in the integral support 5, scraping knife support is short " L " type angle steel of a length of side another side, on long limit and the minor face hole is arranged respectively, the minor face that to scrape knife support with bolt respectively is fixed on front panel and rear board outer upper end, scraper 4 is a strip, two ends have a slotted hole that is parallel to blade respectively, so that regulate when installing, scraper 4 passes from cylinder 6, scraper 4 blades and inner core 12 tops are pressed close to, so that effectively wipe scum off, scraper 4 two ends are fixed by bolts to scraping on the long limit of knife support of front panel and rear board respectively, supporting bearing is fixed by bolts on front panel and the rear board lateral surface, roller bearing is installed in respectively on the supporting bearing of front and back, conveyer belt 7 passes and is installed on the roller bearing from cylinder 6, after installing like this, conveyer belt is positioned at scraper 4 belows.Near on the roller bearing of decelerator 1 one sides a belt pulley is installed, connects belt pulley and decelerator 1 output shaft with belt.During work, motor 2 drives cylinder 6 rotations, slag flows through below the conveyer belt 7 from cylinder 6, the cylinder 6 of rotation is adsorbed on the scum in the slag on inner core 12 inwalls and upwards and rotates, and blocked by scraper 4 when scum goes to the top, but cylinder 6 is rotated further, when 11 positions, interval of 10 of cylinder 6 inner magnets go to the scum place, because magnetic force is very little, scum breaks away from cylinder 6 interior wall energys and drops to exactly on the conveyer belt 7, and conveyer belt 7 is continuously sent scum.
