Description
Technical field:
The present invention relates to a kind of adaptive vibration method and device thereof of hummer screen.
Background technology:
At present, vibratory sieve of the prior art is general to adopt two kinds of methods to vibrate, and a kind of is the mechanical type method for oscillating, and another kind is exactly to adopt the electromagnetic type method for oscillating.The mechanical type method for oscillating is to utilize the eccentric pendulum rotation of driven by motor, make screen tray produce double vibrations, its vibration frequency determined by rotating speed of motor, shortcomings such as the mechanical type method for oscillating exists mainly that noise is big, screening efficiency is low, power consumption is big, wear and tear in machines is big, part damages easily, adjusts difficulty, maintenance cost costliness; And traditional electromagnetic type method for oscillating, the power source that the general solenoid that all is the employing electromagnet maybe can generate an electromagnetic field moves as the driving screen tray, the driving power of its electromagnet or solenoid generally all is to adopt the AC power of fixed frequency or variable frequency or the pulse power as its driving power, therefore the vibration frequency of existing electromagnetic type vibratory sieve is determined by the frequency of driving power, this by driving power the vibratory sieve of definite vibration frequency, its shortcoming is that vibratory sieve generally all is difficult to adapt to the operating frequency that sets, because vibratory sieve is when oscillating movement, can produce certain inertia, this inertia is not only relevant with the structure of vibratory sieve, but also it is relevant with the load of vibratory sieve when working, because the task driven frequency of vibratory sieve is difficult to adapt with its inertia, when vibratory sieve in when work its task driven frequency and its inertia when clashing, this has not only caused the operating efficiency of vibratory sieve to reduce, but also be easy to cause vibratory sieve to damage, so existing vibratory sieve in use, and is still not ideal enough.
Summary of the invention:
The objective of the invention is: provide a kind of high efficiency, simple in structure, not fragile, and can regulate adaptive vibration method and the device thereof of its operating frequency automatically according to the s own situation of vibratory sieve and load condition with the hummer screen of the seismic inertia that adapts to vibratory sieve.
The present invention is achieved in that the adaptive vibration method of its hummer screen is: its employing electromagnet and spring steel plate are as the vibration source of vibratory sieve, and with direct current directly as the driving power of electromagnet, it utilizes the suction-combining force that energising produced of electromagnet and electromagnet outage back to lean on the return elastic force of spring steel plate that the screen tray of vibratory sieve is vibrated, the energising of its electromagnet or outage are by one that connects on the electromagnet coil split type switch control, the part of this split type switch is along with the shaker pan of vibratory sieve moves together, its another part is fixed on the support of vibratory sieve motionless, when electromagnet energising adhesive, drive the screen tray motion of vibratory sieve, the screen tray motion drives the part motion of split type switch, another part of split type switch on making it and being fixed on support separates, thereby make the electromagnet outage, after the electromagnet outage, shaker pan is past swivel motion under the return resilient force of spring steel plate, from and make split type switch in conjunction with energising, so circulation, even the screen tray of vibratory sieve produces double vibrations, closing time that its vibration frequency is produced when being moved with screen tray by split type switch and folding time are determined; Its split type switch can adopt conventional mechanical type contact switches or electronic switch or magnetic-type switch.
Adaptive vibration electric and magnetic oscillation screen device of the present invention is: it comprises screen tray (1), support (2), electromagnet (3) and be provided with dc source and the electric appliance control box of gauge tap (6), on support (2), be fixed with 2～6 steel spring plates (4), and the upper end of every steel spring plate (4) all be connected screen tray (1) below, electromagnet (3) is fixed on the support (2), and the moving armature a of electromagnet (3) is fixed on the support of screen tray (1) below, solenoid one end of electromagnet (3) directly is connected on the output stage of dc source E, " split type switch dimerous (5) is connected with another output stage of dc source E its other end; a part of b ' of split type switch (5) is fixed on the support that moves with screen tray (1), and another part b of split type switch (5) " is fixed on the support (2) by b ' and b by series connection; Split type switch (5) is a part of b ' of being made up of Hall element induced magnet NS and by Hall element H, triode BG1, BG2, resistance R 2～R7, light emitting diode F2, voltage-stabiliser tube DW connects into another part b that on-off circuit is formed " to be formed; the positive pole of the solenoid one termination dc source E of electromagnet (3); receive the negative pole of dc source E behind the collector and emitter of its other end by BG2; the induced magnet NS that forms b ' part is installed on the support that moves with screen tray (1), forms b, and " the Hall element H in the on-off circuit of part is installed near on the support (2) at induced magnet NS place; Hall element H can be substituted by photosensitive tube GM, and induced magnet NS can be substituted by luminous tube FG; Split type switch (5) also can be made up of dry-reed tube switch GH and magnet T, dry-reed tube switch GH connects with the solenoid of electromagnet (3), magnet T is contained on the support that moves with screen tray (1), and dry-reed tube switch GH is installed near on the support (2) at magnet T place; Split type switch (5) also can be made up of the mechanical type contact switches that two metal contacts are combined into; The part that split type switch (5) is installed on the support (2) also can be connected with support (2) with adjusting holding screw (8) by a position of the switch adjustable plate (7); Every angle α that is connected steel spring plate (4) and support (2) vertical line on the support (2) is 10 °～35 °.
Owing to adopted technique scheme, the present invention compared with prior art, the present invention has high efficiency, simple in structure, wear-out part is few, not fragile, and can adapt according to the seismic inertia that the structure situation and the load condition of vibratory sieve are regulated its operating frequency and vibratory sieve automatically and the advantage that do not clash, operating frequency of the present invention is not to resemble the prior art to be determined by the rotating speed of drive motors or the frequency of driving power, but the closing time and the folding time that are produced when moving with screen tray by its split type switch determine, because the closing time or the folding time of split type switch are determined by the motional inertia of two-part initial position of split type switch and screen tray, and the motional inertia of screen tray has not only reflected the driving situation in vibratory drive source, himself structure and load condition have also been reflected, therefore when vibrating screen device of the present invention when working, drive the screen tray motion of vibratory sieve during electromagnet energising adhesive, the screen tray motion drives the part motion of split type switch, another part of split type switch on making it and being fixed on support separates, thereby make the electromagnet outage, after the electromagnet outage, screen tray also can overcome elastic force continuation motion one segment distance of spring steel plate under action of inertia after, ability is past swivel motion under the return resilient force of spring steel plate, from and make split type switch in conjunction with energising, screen tray enters motion next time again, so circulation, just make screen tray produce double vibrations, thereby the inertia that is produced during the vibration of vibratory drive of the present invention source and screen tray is difficult to clash, so the present invention has high efficiency, energy consumption is low, noise is little, working stability is reliable, part is not fragile, advantages such as long service life.
