Description
Technical field:
The utility model relates generally to a kind of vibrosieve equipment, specifically is a kind of vibration slide sieve, and it is used for the material that contains meal and fine powder is carried out classification.
Background technology:
" basic principle of vibratory sieve " of " comminution engineering and equipment " the 4th piece of chapter 2 the 3rd joint that prior art can be consulted is that China Construction Industry Press in November, 1994 publishes, book number is ISBN7-80090-342-7/TH12; " the rectilinear motion vibratory sieve " of the 4th joint; " circle and the elliptic motion vibratory sieve " of the 5th joint, and " probability screen " of the 6th joint.
Existing vibratory sieve, the main brute force of vibration source of leaning on that slides downwards and sieve of material is vibrated, and impels by the meal of sieve powder material, fine particle to produce eduction.Eduction is sunk fine particle gradually, from the upper surface of screen cloth, passes the sieve aperture on the screen cloth, arrives under the screen cloth of vibratory sieve, and is taken as screenings discharge vibratory sieve, and the screenings here is exactly the fine powder that is commonly called as.The meal particle floats because of the sinking gradually of fine particle, can not pass screen cloth and become sieve down from sieve, and slowly slide to the sieve nest lower end.When the meal particle sieves behind the end margin off the net because of sliding downwards to slip, be taken as oversize and discharge vibratory sieve, the oversize here is exactly the meal that is commonly called as.So meal, fine particle obtain screening.
Existing vibratory sieve, the lengthwise dimension of sieve nest approximately are about the twice of width size, and the angle of sieve nest length direction and horizontal plane is less than or equal to 25o.Because the screening path is shorter; The percent of pass of compass screen surface must be very high, just can reach the screening effect of expection, causes the Wear-resistant Treatment of screen cloth very difficult; And the screen life-span of not making the vibratory sieve of Wear-resistant Treatment is lacked, and can't be applied in the systems such as roll squeezer, vertical mill.
Existing vibratory sieve mainly leans on powerful vibration to force coarse granule, fine granular materials to lower slider, and the microcosmic relative motion between material and the screen cloth is stronger, and the wearing and tearing that strengthened screen cloth have also reduced the reliability of other parts of equipment.
Existing vibratory sieve charging aperture and discharging opening all are open types, cause dust from flying easily, are unfavorable for environmental protection.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of vibration slide sieve to be provided, through increasing the length of sieve plate, prolong the screening path, offset the percent of pass that reduces because of Wear-resistant Treatment, guaranteeing screening efficiency.
