Description
Technical field
The present invention relates to a kind of small sieve screening device, particularly a kind of by the rocking type screening plant of Electric Machine Control screening tank hunting frequency, belong to gradation or filtering powder field.
Background technology
Traditional screening plant be a kind of by sieve diameter and screen between particle and have size to distinguish the device of screening, be mainly screen cloth by changing different sieve diameters and the motion mode of adjustable screen, reach the purpose that filters out required size particles.Its function also comprises the drying of washing vegetables, liquid and waste slag produced quick separation etc.At present, the screening plant of domestic production mostly is oscillatory type up and down reciprocatingly, and the material local stops long, and sieve aperture easily blocks, and adjusting function is poor, and production efficiency is lower; Be exactly mostly to be large-scale device in addition, complex structure, cost is high, inapplicable, poor for applicability for the screening purpose of little output, have even also by manually-operated, waste time and energy, effect is also bad.Therefore, develop particularly important that a kind of small-sized, simple, efficient screening plant shows.
The present invention is exactly the deficiency that will overcome existing screening plant, and a kind of screening plant of small-sized efficient is provided.This device utilizes motor to realize the swing type screening mode, can overcome the long and shortcoming of blocking sieve aperture of material Local Residence Time, also can implementation structure simple, stable operation, the requirement of the screening plant that adjusting function is good.
Summary of the invention
The technical problem to be solved in the present invention is: the material screening device that a kind of small-sized efficient is provided, this device is by amplitude of fluctuation and the hunting frequency of Electric Machine Control screening tank, making raw material carry out left and right on screen cloth moves back and forth, reduce the time of staying of material, thereby shortening screening time, improve screening effeciency, reduce costs, also reduced the energy waste that utilizes Large-scale Screening device processing abortion amount material and produce.
In order to address the above problem, the present invention is achieved through technology:
A kind of small-sized electric screening plant, comprise screening tank, charging aperture, screen cloth, discharging opening, outlet material baffle plate, support, rotating shaft, bearing, motor.Screening tank is to be welded by the semicircular cylinder of trunnion axis and end cap, by rotating shaft support; Charging aperture is that taper type is uncovered, with screening tank, is welded; Screen cloth is fixed in the rectangle screen frame, is arranged on the middle place of screening tank, and installation form is detachable, is easy to change the screen cloth of different sieve apertures, meets the screening conditions of various criterion; Discharging opening is positioned at the bottommost of screening tank, the oblong openings shape; The outlet material baffle plate is fixedly mounted on the periphery of screening tank, and together with support welding, and its inwall and screening tank outer wall have certain interval or space, do not affect the whole swing of screening tank; Support is to link together with rotating shaft, bearing, supports whole device; Rotating shaft links together by bearing and support, screening cell body, is positioned at the end of screening cell body; Bearing is connected with screening tank, support, supporting revolving shaft; Motor is connected with rotating shaft by circuit, regulates hunting frequency and the amplitude of screening tank by motor.Screened material is scattered on the screen cloth in screening tank by charging aperture, open motor switch, the screening tank of semicircular cylinder is under the effect of rotating shaft, can vacillate now to the left, now to the right, the whole left and right of material meeting on screen cloth, height is mobile, form dynamic Contact with screen cloth, the material that particle diameter is less than sieve diameter will leak down from screen cloth, pass through material outlet, under the effect of outlet material gear case, be deposited in screening tank under, and particle diameter is greater than the particle of sieve diameter, will drop on screen cloth, finally pass through rotary screen, material is derived from exit, according to required condition, select the screen cloth of different sieve diameters, reach the purpose of separating and filtering.
The screening tank cell body is semicircular cylinder design, and its axis and shaft parallel, be easy to swing, and pendulum angle be take level and is no more than 45 ° as benchmark.
The discharging opening baffle plate is contraction-like box, and outlet at bottom is slightly larger than the screening tank discharging opening, can prevent that the outlet material caused splashes, disperses because the screening tank hunting frequency is too fast, also can be conducive to material and flow out rapidly.
The screen frame two ends are rotary positioner, have both played fixation, can realize again the rotation of whole screen cloth, carry out the subsequent treatment of the material that particle diameter is large.
The screening tank side has the space of a screen frame thickness, is used for realizing the replacing of screen cloth, to be suitable for different screening conditions.
Screen cloth adopts the material that some strength is arranged as far as possible, in the middle of screen frame, reinforcement can be set, and is beneficial to load-bearing.
Adopted technique scheme, the invention has the beneficial effects as follows:
Material enters screening tank, after being scattered on screen cloth, under the effect of motor-driven rotatable shaft, whole screening tank is done the left and right oscillating traverse motion, make to rest on material on screen cloth under the state of motion, and particle diameter is less than sieve diameter, fall down from sieve aperture rapidly, complete the material screening operation.
Therefore, the present invention compares with existing screening plant, and have outstanding advantage and be: (1) is simple in structure, easy to operate, laborsaving saving time; (2) by regulating motor, can change hunting frequency and the amplitude of screening tank, effectively control the stays static time of material on screen cloth, avoid the appearance of choking phenomenon, thereby improved operating efficiency, reduce running cost; (3) setting of outlet material gear case, make the screened material rapid accumulation gone out, and prevents materials from spattering, and adjusting function is good, stable operation.
The invention provides a kind of small sieve screening device, structurally manufacture simple, realized automation control in operation, for practical application provides great convenience, can be widely used in food, medicine, chemical industry, the particles such as light industry, the screening of powder relevant industries, and the occasion of liquid-solid quick separation.
