Abstract
A single-body super-stable energy-saving vibration sieve with high anti-interference power and low power consumption is composed of sieve body, rubber spring, guiding leaf springs, main vibrating springs, drive motor, elastic crank-connecting rod mechanism, supporting frame and basic beams. It features that its working frequency is posioned in the smooth vibration region before resonance point and its main vibrating spring is the non-linear composite one to shift the ampletude-frequency response curve of resonance region toward right, resulting in a wide and smooth vibration region.
Description
Technical field
The invention belongs to vibrating machine, be specifically related to a kind of energy-saving vibration sieve technology.
Technical background
In fields such as current vibrosieve, vibrating transportation, vibration cleaning, the overwhelming majority belongs to off-resonance machinery, and promptly the operating point is positioned at after the resonance region of system, and is far longer than resonant frequency, thereby belongs to off-resonance forced vibration state.Want the operating efficiency that reaches certain, need the bigger energy of input system.As the twin shaft self-synchronizing vibrating screen, in order to reach certain amplitude (thereby having certain oscillation intensity), need to increase eccentric mass and eccentric throw, eccentric massblock itself will expend huge energy, thereby influences the effective power of vibratory sieve.And existing a spot of resonance screens all adopt the piecewise linearity spring as main vibrating, the rigid nonlinear characteristic of this main vibrating is difficult to control and reaches the mild purpose of resonance region amplitude frequency curve before the resonance point, so duty is not very stable, in case system is interfered, as factors such as the variation of the variation of quality of material, spring parameter, variations in temperature, make deviation resonance district, operating point easily, thereby can't reach energy-conservation purpose.As existing double-deck nonlinear resonance sieve, be with the segmentation rubber spring as main vibrating because the influence of factors such as installations makes the gap of piecewise linearity spring be difficult to adjust to optimum state, can't form the interior mild resonance curve of resonance region before the resonance point.Therefore how non-linear main vibration spring reasonable in design to the elemental body vibratory sieve, make the mild transition in system resonance district, operating frequency drops within the mild scope of broad, makes the elemental body vibratory sieve become the elemental body resonance screens, and can be steadily, energy conservation, be problem to be solved by this invention.
Summary of the invention
The object of the present invention is to provide a kind of single super stable energy-saving vibratory sieve that is used for aspects such as material screening, conveying, workpiece cleaning.
Introduce know-why of the present invention below in conjunction with Fig. 1, Fig. 2 and Fig. 3.Single super stable energy-saving screen mainly has: sieve nest 1, rubber spring 2, guiding leaf spring 3, main vibration spring 4, motor 5, elasticity crank connecting link 6 and support 7.Main vibration spring 4 between sieve nest 1 and the foundation beam 8 is rigid non-linear compound main vibration spring.Rigid nonlinear spring can provide mild workspace, thereby realizes the overstable energy-saving run of vibratory sieve.Sieve nest 1 is supported by rubber spring 2, composite material plate spring 3 guiding (as Fig. 1).The rotating speed of design motor 5 is that the operating frequency of energy-saving screen is positioned at resonance point mild resonance region before.The concrete structure of rigid non-linear compound main vibration spring 4 is: two rigid non-linear compound main vibration springs 4 are installed on main vibrating lower carriage 10 inside, the upper surface of one of them main vibrating 4 and main vibrating lower carriage 10 tops are fixed, the bottom of the lower surface of another main vibrating 4 and main vibrating lower carriage 10 is fixed, also fit between described two main vibratings 4 and contact in the lower surface of main vibrating upper bracket 9, main vibrating upper bracket 9 is fixing with sieve nest 1, and lower carriage 10 is fixing with foundation beam 8.(as Fig. 2).This system is the single-degree-of-freedom non-linear vibrating system, and its non-linear rigidity is rigid characteristic, so its resonance curve as shown in Figure 3.Owing to adopt the stronger composite non-linear spring of nonlinear degree, its formant is skew to the right obviously, thereby occurs mild, a roomy amplitude-frequency scope before resonance point.By the spring rate of designing and calculating system, the operating point of vibratory sieve is positioned within this mild zone, thereby still can keeps stable operation when being disturbed in system.Should still belong to resonance region in the zone simultaneously, therefore under the condition of the less energy of input, sieve nest can obtain bigger amplitude, reaches purpose of energy saving.
Beneficial effect of the present invention and advantage are: utilize rigid primary resonance of nonlinear vibration principle, adopt a kind of novel composite non-linear master vibrating, make the operating point of vibratory sieve be positioned at resonance point mild resonance region before, thereby realize the overstable energy-saving run effect of vibratory sieve.The present invention can be used for material screening and career fields such as conveying, workpiece cleaning as product, is expected to become the renewal product of elemental body vibratory sieve.

The specific embodiment
By the following examples and in conjunction with the accompanying drawings principle of the present invention and device are described further.Implementation process is undertaken by an elemental body vibratory sieve model, and structure as shown in Figure 1.In the present embodiment, design parameter is: operating frequency n=750rpm, amplitude X=13mm; Structural parameters are: the mass M=71.9kg of sieve nest 1; The rigidity k of rubber spring 2
2The rigidity k of=53.2kN/m guiding leaf spring 3
3=2.4kN/m; The dynamic stiffness k of main vibrating 4
4=118.8kN/m; Elasticity toggle 6 medi-spring rigidity k
6=353kN/m; Power of motor N=250W, motor speed n
0=1875rpm, driving mechanism gearratio are 2.5.
Starter motor from low speed to 520rpm, treat the stable operation of model sieve after, the amplitude of measuring sieve nest 1 also writes down this value; Continue raising speed to a certain stabilized (steady-state) speed, measure and write down the amplitude of sieve nest 1; So step can obtain the resonance curve of model sieve to 850rpm.
According to the resonance curve of present embodiment actual measurement as shown in Figure 4.As seen the operating frequency of present embodiment design is positioned at resonance point mild resonance region before, and the domain of walker of operating frequency can reach ± 20rpm, stable working state.Through measuring and calculating, reach the common vibratory sieve of same operating efficiency, drive motors power will reach more than the 1200W at least, and the power of this energy-saving screen is 20.83% of common vibratory sieve driving power.As seen energy-saving effect is good.
