Abstract
The invention relates to a vibrating screen with a double-layer screen box, which belongs to the field of vibratory screening machinery and is designed for realizing the aim that an upper-layer screen box and a lower-layer screen box can adopt different vibrating parameters. The vibrating screen mainly comprises electrical machinery transmission devices, vibrators, screen boxes, vibration-damping support devices and a base. The uniaxial or biaxial vibrators are arranged on the screen boxes and are connected with the electrical machinery transmission devices. The vibrating screen is provided with the two screen boxes which are overlapped according to upper and lower layers, wherein the screen box at the upper layer is connected with the screen box at the lower layer through the vibration-damping support devices; the screen box at the lower layer is connected with the base of the vibrating screen through secondary vibration-damping support devices; and the vibration frequencies, the amplitudes and the motion trails of the upper-layer screen box and the lower-layer screen box can be the same or different. The screen boxes can carry out screening with different amplitudes and frequencies according to different granularities, viscosities or proportions of ingredients of materials. The screening efficiency and the processing capacity of the vibrating screen can be improved, and the vibrating screen is applied to vibratory screening of materials required to be classified according to multi-layer.
Description
Technical field
The invention belongs to the vibration screening machinery field, mainly relate to screening needs, the double-deck screen box vibratory sieve that available various amplitude and frequency are sieved according to material.
Background technology
Existing vibratory sieve mainly is made up of transmission gear for electric motor, vibrator, screen box, vibration damping support device and base; When under the drive of transmission gear for electric motor, working, the amplitude of its complete machine is identical with frequency basically.Because the difference of granularity, viscosity and the component ratio of material to be sieved, the vibratory sieve of existing frequency and fixed amplitude can not adapt to the needs of material screening.So will further improve the screening efficiency and the disposal ability of vibratory sieve is the comparison difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of double-deck screen box vibratory sieve, this vibratory sieve can be confirmed different amplitudes and frequency according to the needs of material screening technology, improves the screening efficiency and the disposal ability of vibratory sieve.
The present invention realizes through following measure.Mainly form by transmission gear for electric motor, vibrator, screen box, vibration damping support device and base; Single shaft or dual-axis vibration device are installed on the screen box and with transmission gear for electric motor and are connected; It is characterized in that: vibratory sieve has two screen boxs, and two screen boxs are by the overlapping setting of levels, and the screen box that is positioned at the upper strata is connected with the screen box that is positioned at lower floor through vibration damping support device; The screen box that is positioned at lower floor is connected with the base of vibratory sieve through the secondary vibration damping support device; Vibration frequency, amplitude and the movement locus of upper and lower layer screen box can be identical or inequality.
According to the needs of material screening, upper strata screen box or lower floor's screen box can not be provided with vibrating device.When the screenings of upper strata screen box more after a little while, lower floor's screen box can not be provided with vibrator, perhaps vibrator is not worked.At this moment, lower floor's screen box is equivalent to the vibration isolation frame of a band compass screen surface, through the vibration force of upper strata screen box and following secondary vibration damping support device vibration, realizes the screening operation to less material.Equally, the upper strata screen box also can vibrator be set or vibrator is not worked, and drives the upper strata screen box with the vibration force of lower floor's screen box material is sieved.
The screen box of this vibratory sieve can be a multilayer, and every layer of screen box can be provided with the multilayer compass screen surface.
The invention has the beneficial effects as follows, can select the vibration frequency and the amplitude of each layer screen box according to the characteristics design screen box of material or the number of plies of compass screen surface.Vibratory sieve by multilayer screen box and multilayer compass screen surface are formed can carry out multiple fractionation to material, and can be according to the difference of granularity, viscosity or the component ratio of material, the screening operation of practicable various amplitude of each screen box and frequency.Can improve the screening efficiency and the disposal ability of vibratory sieve, need be applied to the vibrosieve operation of multi-layer classification material.
