The anti-plugging frequency conversion type vibrating screen comprises a screen frame, a base, a screen net, springs, a vibrator and a motor, wherein the screen net is arranged on the screen frame; supporting bars are arranged at the bottom of the screen net; and the springs are arranged between the bottom of the screen frame and the base. The vibrating screen is characterized in that the vibrator is arranged on the top of the screen frame; one end of the vibrator is connected with the motor; the motor is sequentially connected with a frequency converter and an intelligent controller; and a vibrating rod is arranged on one supporting bar at the bottom of the screen net, and is connected with adjacent supporting bars through elastic plates. Compared with the prior art, the vibrating screen has the advantages that the vibrating screen can be subjected to frequency conversion control by the intelligent controller according to the granularity, humidity and viscosity of graded materials and the weight of the materials in the screen, so that vibration frequency can be changed in real time, the optimal screening efficiency can be realized, the abrasion of the materials to the screen net can be reduced, and power consumption can be reduced; and the screen net can generate amplitudes with a certain frequency through the vibrating rod, so that the plugging frequency of screen net holes can be greatly reduced, and the screening efficiency can be improved.
Description
Technical field
The utility model relates to the vibratory sieve field, relates in particular to a kind of anticlogging frequency conversion type vibratory sieve.
Background technology
Along with developing rapidly of industry, vibrosieve equipment is used widely in all kinds of engineerings, and expanding economy is played crucial effects, the key problem of vibration screening machinery these three of screening efficiency, life-span and power consumptions main aspect.Mostly traditional vibratory sieve is under a frequency, to work.Single shaft frequency conversion and twin shaft frequency conversion form have appearred at present; It adopts mechanical speed change to realize; But in screening process, still only under a frequency, work, can not cause screening efficiency low according to the different real time altering vibration frequencies of the granularity of being divided stage material, humidity, viscosity; In addition, sieve screen apertures is often stopped up, and also can cause screening efficiency low.
Summary of the invention
The purpose of the utility model provides a kind of anticlogging frequency conversion type vibratory sieve; Overcome the deficiency of prior art, can improve screening efficiency according to the different real time altering vibration frequencies of the granularity of being divided stage material, humidity, viscosity; Simultaneously on screen cloth, establish vibrating device separately, prevent the sieve screen apertures obstruction.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of anticlogging frequency conversion type vibratory sieve comprises screen frame, base, screen cloth, spring, oscillator and motor, and screen frame is provided with screen cloth; Screen bottom is provided with support bar; Be provided with spring between screen frame bottom and the base, the screen frame top is provided with oscillator, and oscillator one end links to each other with motor; Said motor links to each other with intelligent controller with frequency converter successively, and said screen bottom support bar is provided with vibrating head.
Link to each other through elastic plate between said vibrating head and the adjacent supports bar.
Said oscillator comprises main shaft and eccentric block, and the main shaft two ends that are provided with two eccentric blocks are connected with screen frame respectively.
Compared with prior art, the beneficial effect of the utility model is: the intelligent controlling device can carry out VFC according to the weight of material in the granularity, humidity, viscosity and the sieve that are divided stage material; The real time altering vibration frequency reaches best screening efficiency, reduces the wearing and tearing of material to screen cloth; Save power consumption; Vibrating head can make the amplitude of screen cloth generation certain frequency, significantly reduces the obstruction of sieve screen apertures, improves screening efficiency.
