Description
Technical field
The utility model relates to a kind of high-efficiency and energy-saving type circular shale shaker extension set, belongs to plant equipment field.
Background technology
Traditional vibrating screen classifier is when work, and motor drives eccentric shaft to turn round by belt and belt pulley, and eccentric shaft produces vibration by the centrifugal force of rotation, thereby drives vibrating screen classifier to carry out vibrosieve.But such shortcoming is, the moment of eccentric shaft bias when rotating necessarily cannot change, when starting and shut down because eccentric moment cannot regulate; remain same amplitude running; cause the vibration of vibrating screen classifier when starting and shut down large especially, cause a large amount of dust, contaminated environment.Meanwhile, owing to opening, the strenuous vibration in stopping time, equipment very easily damages.The problems referred to above are not well solved always.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of rational in infrastructure, can automatically regulate oscillatory torque and high-efficiency and energy-saving type circular shale shaker extension set energy-efficient, that operate steadily.
High-efficiency and energy-saving type circular shale shaker extension set described in the utility model, comprise screen box, main shaft and motor, main shaft is installed on screen box, motor is by pulley transmission mechanism drive shaft, automatic eccentric adjustment device is all installed at main shaft two ends, automatically eccentric adjustment device comprises main body, eccentric block, pull bar, spring and spring bearer plate, axis hole is set in main body and is arranged on main shaft by axis hole, main body top arranges a spring bearer plate, a left side for main body, an eccentric block is installed by bearing pin respectively in right both sides, left, right two eccentric blocks are symmetrical, each eccentric block is connected with spring bearer plate by pull bar respectively, mounting spring on pull bar.
This vibrating screen classifier has changed traditional structure, do not re-use eccentric shaft, but use eccentric block instead, provide vibration source, be contained in the automatic Torque-adjusting size of the automatic eccentric adjustment device of the cover of two on main shaft, specific works process is as follows: vibrating screen classifier in the running, eccentric block is under driven by motor, bearing pin by the effect of self centrifugal force in main body outwards opens gradually, haul pull bar simultaneously, pressing spring under spring bearer plate, increase oscillatory torque, thereby reaching vibration source increases gradually, drive vibrating screen classifier smooth starting, carry out the object of vibrosieve, until run well, when vibrating screen classifier is shut down, eccentric block loses centrifugal force, spring reset gradually, head on spring bearer plate, pull bar simultaneously and pull eccentric block to reset, reduce oscillatory torque, thereby reach vibration source, progressively reduce, make vibrating screen classifier slowly stop the object of vibrating, until stop completely.Reach energy-efficient, smooth operation, and reduced dust.
Except above-mentioned points, the screen box of this vibrating screen classifier adopts one bending structure, adopts bender one-shot forming completely, without any welding, increased intensity, this screen box bending part, is changed into and is used large-sized bender flanging by original cutting edge welding, has substituted artificial welding, alleviated workman's labour intensity, reduce production cost, reduced the pollution to environment, improved operating efficiency.Because the intensity of flanging part is better than welding greatly, screen box is not yielding, thereby has solved traditional vibrating screen classifier screen box easily from the problem of commissure craze and transfiguration, extended the service life of equipment, meanwhile, strengthened the aesthetic degree of screen box outward appearance, easy to utilize.
The beneficial effect that the utility model compared with prior art had is:
The utility model is rational in infrastructure, by automatic eccentric adjustment device, can automatically regulate oscillatory torque according to the duty of vibrating screen classifier, thereby realize automation, control, reach energy-efficient object, realize the smooth operation of vibrating screen classifier, reduced the volatilization of dust simultaneously; The screen box of vibrating screen classifier adopts bender one-shot forming completely, and welding position is reduced to minimum point, has alleviated workman's labour intensity, reduce the pollution to environment, reduced production cost, increased intensity, extend the service life of equipment, improved production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1～4, this high-efficiency and energy-saving type circular shale shaker extension set, comprise screen box 1, main shaft 3 and motor 4, main shaft 3 is installed on screen box 1, motor 4 is by pulley transmission mechanism drive shaft 3, automatic eccentric adjustment device 2 is all installed at main shaft 3 two ends, automatically eccentric adjustment device 2 comprises main body 6, eccentric block 5, pull bar 10, spring 9 and spring bearer plate 11, axis hole 8 is set in main body 6 and is arranged on main shaft 3 by axis hole 8, main body 6 tops arrange a spring bearer plate 11, a left side for main body 6, an eccentric block 5 is installed by bearing pin 7 respectively in right both sides, left, right two eccentric blocks 5 are symmetrical, each eccentric block 5 is connected with spring bearer plate 11 by pull bar 10 respectively, on pull bar 10, mounting spring 9.
This vibrating screen classifier has changed traditional structure, do not re-use eccentric shaft, but use double-shaft two-way eccentric block 5 instead, drive, be contained in the automatic Torque-adjusting size of the automatic eccentric adjustment device 2 of the cover of two on main shaft 3, specific works process is as follows: vibrating screen classifier in the running, eccentric block 5 is under motor 4 drives, bearing pin 7 by the effect of self centrifugal force in main body 6 outwards opens gradually, haul pull bar 10 simultaneously, 11 times pressing springs 9 of spring bearer plate, increase oscillatory torque, thereby reaching vibration source increases gradually, drive vibrating screen classifier to carry out the vibratory sieve object of 1 minute, until run well, when vibrating screen classifier is when shutting down, eccentric block 5 loses centrifugal force, spring 9 resets, and heads on spring bearer plate 11, pull bar 10 pulls eccentric block 5 to reset, and reduces oscillatory torque simultaneously, thereby reaching vibration source progressively reduces, make vibrating screen classifier slowly stop the object of vibration, until stop completely, finally reach idle operation and meritorious operation, energy-efficient, smooth operation, and reduced the volatilization of dust.
Except above-mentioned points, the screen box of this vibrating screen classifier adopts one bending structure, adopts bender one-shot forming completely, without any welding, increased intensity, this screen box bending part, is changed into and is used large-sized bender flanging by original cutting edge welding, has substituted artificial welding, alleviated workman's labour intensity, reduce production cost, reduced the pollution to environment, improved operating efficiency.Because flanging intensity is partly better than welding greatly, screen box is not yielding, thereby has solved traditional screen box easily from the problem of commissure craze and transfiguration, has extended the service life of equipment, meanwhile, has strengthened the aesthetic degree of screen box outward appearance, easy to utilize.
