Abstract

The utility model discloses an electric swinging sieving analyzer for wet or dry materials, which changes the sieve of an existing vibration sieve into the form from inside to outside and sheathing layers by layers. A sieve frame is increased by degrees from inside to outside, while a sieve mesh is decreased by degrees. The sieve frame of the original sieve is changed into the form of the sieve frame column of the sieve frame supporting the surrounding sieve mesh, and the sieve is fixed on the close over of the sifter by means of the sieve frame. The sifter close over with multiple layers of sieves is covered into the outer housing of a sifter barrel body, the fastening bolt of the sifter is fastened, and the whole sifter is fixed on an electric swinging base in a sealing way. The utility model can be electrically swung and sieved after adding the materials from a material inlet positioned an upper part.

Description

Electric swinging sieving analizer for wet or dry materials

The utility model is to be used for sieving fine grained or granular material (as coal slime, mineral fine, flour etc.), thereby measures the mechanical device of its granularmetric composition.Its screen frame with existing bushing screen makes the frame post into and supports, place screen cloth on every side, changed the original form of only sieving from the bottom surface screen cloth, by bottom surface and the comprehensive screening of screen cloth all around, thereby the easily stifled shortcoming of screen cloth when having overcome little the screening, make screening more effective thoroughly, and can adopt wet method, two kinds of screenings of dry method.

The artificial wet sieving of the many employings of thin material screening (as coal slime) in the past is with bushing screen rank ground screening one by one.Compass screen surface is easily stifled during operation, and material is easily excessive, and human error is bigger.During the utility model wet sieving, the current that the multilayer bushing screen produces by mechanical oscillation in the water effect of washing away helps screening.Because bushing screen sieve aperture from inside to outside diminishes step by step, once screening just can draw the size consist of multiple grade.It is earlier the bushing screen (4,7) that will measure the corresponding sieve aperture of granularity to be fixed on sifter big envelope lid (5) by screen frame post clamp nut (2) to go up (ginseng accompanying drawing).Capping (5) lid that installs bushing screen is gone into sifter staving shell (8), use sifter fastening bolt (1,11) fixing seal on electricity shakes base (12).

During dry sieving, directly material is packed into from the material inlet (3) of sifter capping, cover feeding mouth and just can sieve.During wet sieving, clear water, material are added, after liquid level reaches certain altitude, just can cover feeding pipe and sieve, after screening is rinsed well, open the sifter capping, take off the oversize of each sieve, just can draw the result of various size consists after the oven dry weighing.

This sifter can with bushing screen and shell be made square or other shape, and the bushing screen sieve aperture is by the national standard manufacturing, and bushing screen has several layers from inside to outside, and sieve aperture reduces step by step.

Claims

1, shake wet, dry sieving analyzer of the utility model electricity is to be used for powdery and plasma sieve classification, measures the equipment of granularmetric composition, and it is made up of the multilayer bushing screen, it is characterized in that bushing screen from inside to outside, layer overlaps, and sieve aperture reduces step by step, and outermost layer is for sealing staving.

2, device according to claim 1 is characterized in that the screen frame around the bushing screen made by screen cloth and is trapped among on the screen frame post, forms netted screen frame, and by the screen frame post bushing screen is fixed on the sifter big envelope and covers.

3, device according to claim 1 is characterized in that skin has airtight staving, on reinforced, filler is arranged, downside has drainpipe, its staving makes sifter form an integral body by the screening fastening bolt, is fixed on electricity and shakes on the base.
