Abstract

The invention is intended for screening and crushing of material and can be used in installations (flow lines) for the separation and sorting of waste metallurgical and foundry slags. The goal is to increase the efficiency of the device in the separation of slag from metal. Above the vibrating screen 1, a frame (P) 16 is installed with crushing devices in the form of wedges (K) 22 with heads (D) 23 in their upper part. In addition, in R 16 there are holes in which K 22 is installed. R 16 is installed with the possibility of moving in a vertical plane, and K 22 in holes R 16. The transverse dimension D 23 is larger than the transverse dimension of the frame holes. The material located on the vibrating screen 1, under the action of vibration, interacts with К 22, which, in turn, move in the openings of Р 16. During the vibrating screen, the material additionally receives an effect from К 22. 3 Il.

when separating slag from metal. Above the vibrating screen 1, a frame (P) 16 is installed with crushing devices in the form of wedges (K) 22 with heads (D) 23 in their upper part. At that, in R 16 there are holes in which K 22 is installed, R 16 is installed with the possibility of movement in the vertical plane, and K 22 is in the hole. The invention relates to devices for crushing and screening of the material and can be used in installations, flow lines for separation and sorting of dump metallurgical and foundry slags.

The purpose of the invention is to increase the efficiency of the device in the work when separating slag from metal.

FIG. 1 shows a flow line, general view; in fig. 2 shows section A-A in FIG. one; FIG. 3 is a view B of FIG. 2

The flow line, where a crushing and screening device is used, consists of a vibrating screen 1 installed above the hopper 2 and connected by a belt conveyor 3 to a vibratory crusher 4, which, in turn, is connected by a belt conveyor 5 to a vibrating screen 6. The last belt conveyor 7 is connected to cumulative bunker 8 and sklezy 9 with a storage bin 10. Storage bins 8 and 10 have doses of Torah 11. Electromagnetic tenarators 12 and 13 are located above belt conveyors 3 and 5, which dump metal into storage tanks ary 14 and 15.

Above the vibrating screen 1 is placed a frame 1b with openings, which is connected via a shock absorber 17 to a carriage 18 mounted on rails 19 having stops 20, rollers 21. In the frame 16, there are freely mounted crushing devices in the form of wedges 22 with heads 23, with the diameter of the heads 23 being larger than the diameter of the opening of the frame 1b “The frame 16 has a 2k drive, which is placed on a three-walled chamber 25, having a 26 drive

of the room and mounted on rails 27 by wheels 28. Next to the vibrating screen 1 there is a fixed wall 29 with a ventilation outlet 30. On

Styles P 16. The transverse dimension G 23 is larger than the transverse dimension of the holes in the frame. The material located on the vibrating screen 1, under the action of vibration, interacts with К 22, which, in turn, move in the holes of Р 16. During the vibrating screen, the material additionally receives an effect from К 22. 3 Il.

The rails 31 above the vibrating screen 1 have a crane 32 with a magnetic washer 33. The slag 34 cooled naturally in the bucket is discharged by means of the crane 32 onto the vibrating screen 1. The three-wall chamber 25 is moved along the rails 27 by the actuator 26 and is pressed against the fixed wall 29. After the camera 25 stops, the 2k drive lowers the frame -16 with wedges 22 along the rails 19 until the rollers 21 contact the stops 20 and the wedges 22 contact the slag 34. The bottom surface of the heads 23 is raised above the frame 16 to a height H which is less than the height slag size h. Moreover, the size h must be greater than 10 mm of the resonant amplitude of vibrations of the vibrating screen 1 when it starts and stops to prevent the wedges 22 from striking the vibrating screen 1. When the rollers 21 contact the stops 20, a suction vent connected to the outlet 30 is switched on , and vibrating screen 1. Under the action of vibration forces and the weight of wedges 22, a slag ingot is scattered on pieces of slag and metal enclosed in it. All slag and metal less than 100 mm in size pass through the vibrating screen 1 and through the hopper 2 and fall onto the belt of the conveyor belt 3, where electromagnetic metal separates 12 and separates the metal into storage container k. The mixture of slag with metal is then crushed on a vibratory crusher 6 and fed to a conveyor belt 5, from which the separator 13 dumps the metal into an accumulation container 15. The fine fraction is sieved on a vibrating screen b and the conveyor belt 7 is transported to a storage bin 8, and large in a slip 9 enters storage hopper 10, From storage hoppers 9 and 10 up to 15W

the jams 11 slag loaded into cars or cars.

After the shutdown of the vibrating screen 1, the actuator 2A lifts the frame 16, and the actuator 26 retracts the three-walled chamber 25 to the initial position. The metal 1 remaining on the vibrating screen is picked up by crane 32 and transported to the loading yard. Metal u in storage containers 14 and 15 also goes there.
