Abstract
The utility model discloses a double-layer elliptic vibrating screen with equal thickness, comprising a screen basket and a frame, the lower part of the screen frame is provided with second vibration isolating system and a damping device, the inner side of the screen frame is provided with two layers of screen surfaces, the center of the screen frame is provided with an eccentric block three-shaft vibrator, two motors are arranged on the supporting frame which is arranged on one side of the screen frame at the same height with the three-shaft vibrator, the two motors are separately provided with a seven-shaft synchronizer through a pin coupling, the three output shafts of the seven-shaft synchronizer are separately connected with the three input shafts of the three-shaft vibrator through a universal joint shaft linking device, flexible discs are connected between vibrating shafts arranged on the two ends of the eccentric block three-shaft vibrator, and the utility model has the following effect that because two motors are used to drive the double-layer screen surface to work, the utility model has the big power, the reliable working condition, the low dynamic load, being widely applied and the high screen efficiency.
Description
Technical field:
The utility model relates to vibratory sieve, and particularly a kind of power is big, working stability is reliable, the double-layer oval-shaped equal-thickness vibrating screen that screening efficiency is high.
Background technology:
Traditional oval-shaped equal-thickness vibrating screen, include screen frame and support, be supported with two-stage vibration isolation system and vibration absorber below the screen frame, three shaft vibration devices are installed on the screen frame, a motor is installed on the support of screen frame one side, motor drags three synchronizeds through driving belt, and three output shafts drive vibrator through gimbal coupling respectively on three synchronizeds.The shortcoming that exists is because of its power has only a motor, and driving belt skids and is difficult for adjusting, three synchronized temperature height, and fragile parts are unfavorable for improving screening efficiency.
Summary of the invention:
The purpose of this utility model provides that a kind of power is big, working stability is reliable, the double-layer oval-shaped equal-thickness vibrating screen that screening efficiency is high.
Task of the present utility model is finished as follows, it includes screen frame and support, the screen frame lower support has two-stage vibration isolation system and vibration absorber, it is characterized in that: two-layer compass screen surface is arranged in the screen frame, the screen frame middle part is equipped with an eccentric block formula three shaft vibration devices, on the support of screen frame one side, two motors are installed with three shaft vibration devices are contour, be connected with seven synchronizeds with a pin coupler respectively on two motor shafts, three output axle heads of seven synchronizeds are connected with three power shafts of three shaft vibration devices through a gimbal coupling respectively.Between each vibrating shaft of the two ends of eccentric block formula three shaft vibration devices, be connected with flexible disc respectively.
The utility model has following effect: drive double-deck compass screen surface work because of adopting Dual-motors Driving, so power is big, reliable, dynamic loading is little, applicable situation is wide, screening efficiency is high.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the side view of Fig. 1, and Fig. 3 is a conventional system architecture schematic diagram of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing.Double-layer oval-shaped equal-thickness vibrating screen of the present utility model includes two-stage vibration isolation system 4 and seal closure 5, vibration absorber 6, screening funnel 8, chute 9 before the sieve, be provided with two-layer compass screen surface 2 in the screen frame 1, the screen frame middle part is equipped with an eccentric block formula three shaft vibration devices 3, on the support 11 of screen frame one side, two motors 12 are installed with three shaft vibration devices, 3 equal altitudes, three output axle heads that are connected with 10, seven synchronizeds of one seven synchronizeds with a pin coupler 14 respectively on two motor shafts link to each other with three power shafts of three shaft vibration devices through the outer power transmission shaft of a gimbal coupling 13 respectively.In order to make three shaft vibration devices reliable, improve phase compensation effect, between each vibrating shaft of the two ends of eccentric block formula three shaft vibration devices, be connected with flexible disc 15 respectively.
