Description
Technical field
The invention belongs to the chemical substance processing technique field, especially relate to a kind of vibratory sieve that can allow discharging reduce dust.
Background technology
Vibratory sieve is that answering of utilizing the oscillator exciting to produce revolved type vibration and work.The upper rotation weight of oscillator makes compass screen surface produce the plane whirling vibration, and lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes the compass screen surface generation revolve again the type vibration.
Material needs to be sieved after granulation, fragmentation, by aperture, different screen clothes filters out qualified material, in the prior art, due to vibratory sieve in the course of the work, produce a large amount of dust, although be provided with and draw wind apparatus in the sieve nest upper end, but material causes product defective also usually existing a large amount of dust in the discharging opening discharging, screen cloth that need to be less by aperture is proceeded screening, wastes time and energy, and cost of idleness.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of easy operating simple in structure, the cost-saving a kind of vibratory sieve that can allow discharging reduce dust of high efficiency, especially is applicable to screening calcium hypochlorite material.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of vibratory sieve that can allow discharging reduce dust comprises sieve nest, electric device, draws wind apparatus; Described sieve nest is connected with electric device, and the upper end of described sieve nest is provided with charging aperture, and the lower end of described sieve nest is provided with the particulate discharging opening; Be provided with two-layer screen cloth in described sieve nest, the below of every layer of screen cloth is all corresponding is provided with a polythene net, be equipped with some dividing plates between every layer of screen cloth and polythene net, be equipped with some silica-gel spheres between every two dividing plates between every layer of screen cloth and polythene net, the diameter of described silica-gel sphere is 5mm; The aperture of upper strata screen cloth is 1.4mm, and the upper surface of upper strata screen cloth is communicated with large grain feed back pipe, and the other end of large grain feed back pipe is connected with the particulate discharging opening, and the aperture of lower screen is 355 μ m, and the upper surface of lower screen is communicated with qualified grain discharge nozzle; The upper end of the upper end of described sieve nest and qualified grain discharge nozzle all is provided with and draws wind apparatus by pipeline.
Further, be provided with sack cleaner connecting on the described pipeline that draws wind apparatus.
Further, the aperture of described polythene net is 5cm.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, because the upper end at qualified grain discharge nozzle is provided with, draw wind apparatus, can greatly reduce the Dust Capacity of qualified material, do not need repeatedly to be done over again, qualification rate is high, high efficiency; Be provided with the processing that sack cleaner is more conducive to dust, avoid contaminated environment; Owing to being provided with silica-gel sphere, be more conducive to the screening of material by the silica-gel sphere impact screen; Make screening materials carrying convenient; There is simple in structure, high efficiency, the advantage such as cost-saving.

The specific embodiment
As shown in Figure 1, a kind of vibratory sieve that can allow discharging reduce dust of the present invention, comprise sieve nest 1, electric device 2, draw wind apparatus 3; Described sieve nest 1 is connected with electric device 2, and the upper end of described sieve nest 1 is provided with charging aperture 4, and the lower end of described sieve nest 1 is provided with particulate discharging opening 5; Be provided with two-layer screen cloth in described sieve nest 1, the below of every layer of screen cloth is all corresponding is provided with a polythene net 6, be equipped with some dividing plates 7 between every layer of screen cloth and polythene net 6, be equipped with some silica-gel spheres 8 between every two dividing plates 7 between every layer of screen cloth and polythene net 6, the diameter of described silica-gel sphere 8 is 5mm; The aperture of upper strata screen cloth 12 is 1.4mm, the upper surface of upper strata screen cloth 12 is communicated with large grain feed back pipe 9, the other end of large grain feed back pipe 9 is connected with particulate discharging opening 5, and the aperture of lower screen 13 is 355 μ m, and the upper surface of lower screen 13 is communicated with qualified grain discharge nozzle 10; The upper end of the upper end of described sieve nest 1 and qualified grain discharge nozzle 10 all is provided with and draws wind apparatus 3 by pipeline.
Be provided with sack cleaner 11 connecting on the described pipeline that draws wind apparatus 3.
The aperture of described polythene net 6 is 5cm.
The course of work of this example: material is through granulation, after fragmentation, pour vibratory sieve into by charging aperture 4, start electric device 2 and control the motor-vibro screen motion, because sieve nest 1 is downward-sloping, underproof large granular materials is stayed on upper strata screen cloth 12, from large grain feed back pipe 9, flow out, underproof granule flows out by particulate discharging opening 5 at the lowermost end of sieve nest 1, be transported to granulating working procedure by screw feeder after large grain and fine mix and carry out granulation again, qualified material is stayed on lower screen 13, by qualified grain discharge nozzle 10, flow out, because being provided with, the upper end at qualified grain discharge nozzle 10 draws wind apparatus 3, avoided qualified material to have a large amount of dust, cause product defective.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
