Abstract
The utility model discloses a magnetic-separation cylinder for a dry type permanent magnetic separator, belonging to the technical field of dry type permanent magnetic separators, and comprising a cylinder shell installed on a support shaft. A core cylinder is fixedly installed on the support shaft, a magnetic system is fixedly installed at the periphery of the core cylinder, an air flow channel is formed by a gap between the magnetic system and the cylinder shell, a baffle plate is arranged in the core cylinder and divides the core cylinder into an air inlet chamber and an air outlet chamber which are communicated by the air flow channel, an air inlet blind hole and an air outlet blind hole are arranged on the support shaft which is provided with a plurality of radial through holes, the air inlet blind hole and the air inlet chamber are communicated by the radial through holes, and the air outlet chamber and the air outlet blind hole are communicated by the radial through hole. The magnetic-separation cylinder is simple in structure, solves the technical problem that when the dry type permanent magnetic separator runs, the temperature in the magnetic cylinder is too high so as to result in hysteresis loss and further affect the magnetic separation effect, and is widely applied to the manufacturing industry of the dry type permanent magnetic separators.
Description
Technical field
The utility model relates to dry type permanent magnetic separator technical field, relates in particular to a kind of magnetic separation cylindrical shell of dry type permanent magnetic separator.
Background technology
During the running of dry type permanent magnetic separator, because the magnetic separation drum speed is fast (about per second 3.7m) too, the magnetic separation cylindrical shell cutting magnetic line that metal material is made, cause the variation of magnetic separation inner barrel magnetic flux and produce induced potential and induced current, form eddy current, constantly consume external energy and cause heating, cause the magnetic hystersis loss phenomenon, influence the magnetic separation effect and the operate as normal of magnetic separator.Therefore, how to make to keep constant temperature in the magnetic separation cylindrical shell, it is a great problem of puzzlement dry type permanent magnetic separator manufacturer that the magnetic hystersis loss phenomenon no longer takes place.
The utility model content
Technical problem to be solved in the utility model is: a kind of dry type permanent magnetic separator magnetic separation cylindrical shell is provided, and when turning round to solve the dry type permanent magnetic separator, magnetic separation inner barrel temperature is too high, causes magnetic hystersis loss to influence the technical problem of magnetic separation effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: dry type permanent magnetic separator magnetic separation cylindrical shell, comprise the cylindrical shell housing, described cylindrical shell housing rotates and is installed on the back shaft, be installed with the core tube on the described back shaft, described core tube is seal-installed in the described cylindrical shell housing, and the periphery of described core tube is installed with magnetic system, and the gap between described magnetic system and the cylindrical shell housing forms gas channel; Be provided with a dividing plate in the described core tube, described dividing plate is divided into inlet chamber and outlet chamber with described core tube, and described back shaft passes described dividing plate, and described inlet chamber is communicated with by described gas channel with outlet chamber; The two ends of described back shaft are respectively equipped with axially extended air inlet blind hole and the blind hole of giving vent to anger, described back shaft is provided with some radial direction through hole, described air inlet blind hole is communicated with by described radial direction through hole with inlet chamber, and described outlet chamber is communicated with by described radial direction through hole with the blind hole of giving vent to anger.
After having adopted technique scheme, the beneficial effects of the utility model are: because the two ends of back shaft are respectively equipped with axially extended air inlet blind hole and the blind hole of giving vent to anger, the air inlet blind hole is communicated with by radial direction through hole with inlet chamber, outlet chamber is communicated with by radial direction through hole with the blind hole of giving vent to anger, during use, the air inlet blind hole connects air blast, the blind hole of giving vent to anger connects induced-draught fan, air communication is crossed the air inlet blind hole and is entered inlet chamber, enters outlet chamber by gas channel then, discharges by the blind hole of giving vent to anger under the induced-draught fan effect then, in the process that air-flow is flowed through in the magnetic separation cylindrical shell, because the existence of dividing plate, the route of flowing through prolongs, and the area of flowing through increases, the heat that produces is pulled away immediately, make magnetic separation inner barrel temperature keep constant, reduced magnetic hystersis loss, improved the magnetic separation effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, back shaft, 11, the air inlet blind hole, 12, the blind hole of giving vent to anger, 13, radial direction through hole, 2, the cylindrical shell housing, 21, gas channel, 3, magnetic system, 4, the core tube, 41, inlet chamber, 42, outlet chamber, 5, dividing plate, 6, belt pulley, 7, installing rack.
The specific embodiment
As shown in drawings, a kind of dry type permanent magnetic separator magnetic separation cylindrical shell, comprise cylindrical shell housing 2, described cylindrical shell housing 2 rotates and is installed on the back shaft 1, usually, cylindrical shell housing 2 rotates by bearing and is installed on the back shaft 1, both sides at bearing are provided with seal, are installed with core tube 4 on the described back shaft 1, and described core tube 4 is seal-installed in the described cylindrical shell housing 2, it is 3 that the periphery of described core tube 4 is installed with magnetic, described magnetic be 3 and cylindrical shell housing 2 between the gap form gas channel 21; Be provided with a dividing plate 5 in the described core tube 4, described dividing plate 5 is divided into inlet chamber 41 and outlet chamber 42 with described core tube 4, and described inlet chamber 41 is communicated with by described gas channel 21 with outlet chamber 42, and described back shaft 1 passes described dividing plate 5; The two ends of described back shaft 1 are respectively equipped with the axially extended air inlet blind hole 11 and the blind hole 12 of giving vent to anger, described back shaft 1 is provided with some radial direction through hole 13, described air inlet blind hole 11 is communicated with by described radial direction through hole 13 with inlet chamber 41, and described outlet chamber 42 is communicated with by described radial direction through hole 13 with the blind hole 12 of giving vent to anger.
Its operation principle is as follows:
During use, back shaft 1 is fixedly mounted on the frame by installing rack 7, and cylindrical shell housing 2 is fixedly connected with the belt pulley 6 that is driven by motor reducer, and cylindrical shell housing 2 is high speed rotating under the drive of belt pulley 6, carries out magnetic concentration working.Air inlet blind hole 11 connects air blast, the blind hole of giving vent to anger 12 connects induced-draught fan, air communication is crossed air inlet blind hole 11 and is entered inlet chamber 41, enter outlet chamber 42 by gas channel 21 then, under the induced-draught fan effect, discharge then by the blind hole 12 of giving vent to anger, the heat that the magnetic separation cylindrical shell produces is pulled away immediately, has avoided magnetic separation inner barrel portion temperature too high, causes magnetic hystersis loss and influences the magnetic separation effect.
