Detailed Description
Referring to fig. 1-5, the belt type automatic magnetic separator comprises a bracket 1, wherein magnetic rollers 2 are respectively arranged at two ends of the bracket 1, a conveying belt 3 is arranged between the two magnetic rollers, one magnetic roller is connected with a driving motor, a feeding device 4 is arranged at the upper side of the rear end of the conveying belt 3, a magnetic plate 5 for supporting the inner bottom surface of the conveying belt is arranged at the upper side between the two magnetic rollers 2, a first receiving hopper 6 is arranged at the bottom of the front end of the conveying belt, a first conveying belt component 7 is arranged at the lower part of the first receiving hopper 6, a second receiving hopper 8 is arranged at the lower side of the conveying belt, a second conveying belt component 9 is arranged at the lower part of the second receiving hopper, a scraping plate 10 is arranged at the bottom of the conveying belt, and the scraping plate 10 is attached to the bottom surface of the conveying belt.
The conveyer belt is formed by the alternate fixed connection in proper order of polylith stiffening plate 11 and soft board 12, the inside cavity 13 that has of soft board 12, soft board can select materials that can take place to warp such as rubber, the both ends of stiffening plate all set up folding gasbag 14, the upper portion bilateral symmetry of conveyer belt sets up curb plate 15, curb plate fixed connection is on the support, the curb plate inboard sets up the extrusion piece 16 that the inboard extends of several along the conveyer belt direction, folding gasbag is linked together with wherein cavity 13 that one side is adjacent, the inboard extrusion piece dislocation set of two curb plates, be extruded when folding gasbag passes through the extrusion piece, the inside air of folding gasbag is received in the extrusion back enters into corresponding cavity, this soft board 12 is inflated and is expanded, the extrusion piece is applied thrust to the opposite side through folding gasbag for corresponding stiffening plate this moment, under the effect of this thrust, this stiffening plate is to one side skew certain distance. Because the soft board 12 has certain deformability, the thrust directions that two adjacent hard boards received are opposite and offset a bit distance to different directions, the material can roll relatively to the hard board because of inertia, the soft board of cooperation intermittent type inflation, the material on the conveyer belt takes place to roll constantly, receive the effect of magnetic plate appeal, can be by the impurity of magnetic attraction can slowly sink to the bottom and adsorb on the conveyer belt surface, the material is when the conveyer belt passes the magnetic roller along with the conveyer belt, other non-absorbed components fall on the first conveyer belt subassembly 7 after first receiving hopper 6 and by the transportation other processes, can be by the impurity of magnetic attraction falls on the second conveyer belt subassembly 9 after the second receiving hopper and by the transportation collection.
