Description
Technical field
The utility model belongs to chemical substance processing technique field, especially relates to a kind of vibratory sieve that can allow discharging reduce dust.
Background technology
Vibratory sieve is to utilize type vibration and the work of revolving of answering that oscillator exciting produces.The upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, and lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes compass screen surface generation revolve again type vibration.
Material needs to sieve after granulation, fragmentation, by the different screen cloth in aperture, filter 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 sieve nest upper end, but material causes product defective also usually existing a large amount of dust in discharging opening discharging, need to proceed screening by the less screen cloth in aperture, waste time and energy, cost of idleness.
Utility model content
Problem to be solved in the utility model is to provide a kind of easy operating simple in structure, the high cost-saving a kind of vibratory sieve that can allow discharging reduce dust of operating efficiency, is especially applicable to screening calcium hypochlorite material.
For solving the problems of the technologies described above, the technical solution adopted in the utility model 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 particulate discharging opening; In described sieve nest, be provided with two-layer screen cloth, the below of every layer of screen cloth is all corresponding is provided with a polythene net, between every layer of screen cloth and polythene net, be equipped with some dividing plates, between every two dividing plates between every layer of screen cloth and polythene net, be equipped with some silica-gel spheres, 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 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 is all provided with and is drawn wind apparatus by pipeline.
Further, on the pipeline that draws wind apparatus described in connecting, be provided with sack cleaner.
Further, the aperture of described polythene net is 5cm.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, owing to being provided with and drawing wind apparatus in the upper end of qualified grain discharge nozzle, can greatly reduce the Dust Capacity of qualified material, do not need repeatedly to do over again, qualification rate is high, and operating efficiency is high; Be provided with the processing that sack cleaner is more conducive to dust, avoid contaminated environment; Owing to being provided with silica-gel sphere, by silica-gel sphere impact screen, be more conducive to the screening of material; Make screening materials carrying convenient; Have simple in structure, operating efficiency is high, 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 utility model, comprises sieve nest 1, electric device 2, draws 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; In described sieve nest 1, be provided with two-layer screen cloth, the below of every layer of screen cloth is all corresponding is provided with a polythene net 6, between every layer of screen cloth and polythene net 6, be equipped with some dividing plates 7, between every two dividing plates 7 between every layer of screen cloth and polythene net 6, be equipped with some silica-gel spheres 8, 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 is all provided with and is drawn wind apparatus 3 by pipeline.
On the pipeline that draws wind apparatus 3 described in connecting, be provided with sack cleaner 11.
The aperture of described polythene net 6 is 5cm.
The course of work of this example: material is through granulation, after fragmentation, by charging aperture 4, pour vibratory sieve into, start electric device 2 and control 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, after large grain and fine mix, by screw feeder, be transported to granulating working procedure and carry out granulation again, qualified material is stayed on lower screen 13, by qualified grain discharge nozzle 10, flow out, owing to being provided with and drawing wind apparatus 3 in the upper end of qualified grain discharge nozzle 10, avoided qualified material to have a large amount of dust, cause product defective.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
