The raw material that the present invention relates to the slurrying industry is got the raw materials ready, particularly a kind of to the grass joint in the careless class tablet, blade of grass, sandstone, dust etc. screen, the method and apparatus of removal of impurities.
Background technology
At present the screening and the dedusting of paper industry grass as raw material that slurrying is used are to adopt sieve plate mostly, utilize tablet to separate with the different realizations of physical dimension of impurity, and generally all can only realize single separation.Can't realize separating for blade, impurity that the blade of grass equidimension is suitable.Want to realize that multi-stage separation then must adopt the plurality of devices series connection to use, and separating effect is not fully up to expectations.
Summary of the invention
At the above-mentioned defective that exists in the prior art, the invention provides a kind of blade impurity-removing method and equipment, it can carry out removal of impurities and classification to blade simultaneously, especially can realize approaching material and separate impurities of physical dimension such as blade of grass, grass joint, blades, can effectively improve the qualification rate of raw material, improve the slurrying quality.
Method of the present invention is achieved by the following technical solution:
A kind of blade impurity-removing method, it is that the material that will contain impurity such as careless bar, blade of grass, sandstone, dust tangentially is conveyed into impurity removing equipment with air-flow, make material in impurity removing equipment, form the material flow of rotation, utilize centrifugal force to make material layering, components different in the material are discharged from different outlets according to the density size, described impurity removing equipment has the cylindrical shell that can form eddy flow, cylinder top has the member that is used for the less impurity of partition density that is in described eddy flow center, be useful on the outlet of discharging the bigger impurity of density on the barrel wall, clean material is discharged from the cylindrical shell bottom.
The present invention is a centrifugal force difference of utilizing the batch ingredients of different densities to be produced in the high speed rotary course, thereby makes the batch ingredients of different densities be in different positions and layering in eddy flow, and then separates.At a high speed in the logistics of rotation, the flying dust that density is little, blade of grass enter the central cyclone band, and discharge respectively by separating member, the sand grains of density maximum, grass joint etc. are thrown on the barrel of cylindrical shell by air-flow under action of centrifugal force, discharge in the downslide of the effect lower edge of gravity barrel and by the outlet on the barrel, and clean material is discharged from the cylindrical shell bottom.
Equipment of the present invention is achieved by the following technical solution:
A kind of blade impurity removing equipment, it comprises cylindrical shell, described cylindrical shell has columned upper shell and cone shape lower shell, the upper shell top is provided with end cap, pass this end cap central vertical with the dust outlet that is used to remove dust of exterior and extend to inner barrel, be used to remove coaxial being arranged in the dust outlet of blade of grass outlet of blade of grass, form an annular gap between dust outlet and the blade outlet, the charging aperture that is used to import air-flow and material is arranged on the upper shell place and communicates with inner barrel along the barrel tangential direction, the lower shell bottom is connected with clean blade bin, and the barrel of described cylindrical shell is provided with at least one heavy seeds outlet.
The present invention is achieved in that to screening, the removal of impurities of blade air-flow brings blade into cylindrical shell along the equipment barrel tangential direction, rotation at a high speed behind the material flow access arrangement, under action of centrifugal force, realize material layering, the flying dust that density is little, blade of grass enter the central cyclone band, the flying dust of density minimum is discharged from the outlet of top dust, the less blade of grass of density is discharged from the outlet of top blade of grass, the sand grains of density maximum, grass joint etc. are thrown on the barrel of cylindrical shell by air-flow under action of centrifugal force, and by heavy seeds outlet discharge, clean blade falls into clean blade bin.
Suitable in order to guarantee the air-flow in the cylindrical shell, the cone angle of lower shell of the present invention is: the 10-30 degree.
In order to guarantee that the dust that is in the central area fully separates with blade of grass, the part of described blade of grass outlet in cylindrical shell extends downward outside the dust outlet.The length of stretching out is preferably: 10-30cm.
For above-mentioned same purpose, described blade of grass outlet preferably gos deep into inner barrel 30-60cm.
Heavy seeds outlet among the present invention can be arranged on any position of cylindrical shell, for example can be arranged on the upper shell of cylindrical shell or be arranged on lower shell, and its quantity can be provided with a plurality of.Generally, stable in order to guarantee the wind-force field in the cylindrical shell, the heavy seeds outlet need seal relatively with cylindrical shell usually.Discharge smoothly for the ease of heavy seeds, usually, the barrel that is arranged on heavy seeds outlet and lower shell on the lower shell is provided with at an angle, and this angle is preferably 20-50 degree angle.
In order effectively to separate dust and blade of grass, the annular gap size between described blade of grass outlet and the dust outlet is: 20-50mm.
When discharging for the clean blade in clean blade bin in the cylindrical shell wind-force field stable, but be respectively equipped with the flashboard of folding in the lower end of clean blade bin and lower shell junction and clean blade bin, the flashboard of junction, top cuts out in blowing, the bottom flashboard is opened, the flashboard that blade is closed the bottom after putting only, open the flashboard on top, like this, can guarantee that whole cylindrical shell also can be in the state of relative sealing when blowing, thereby avoid influencing the screening effect of forage because of the wind-force field in the cylindrical shell changes.
For ease of the blade of grass that collection is separated, the port of export of described blade of grass outlet passes the tube wall and the exterior of dust outlet.
The invention has the beneficial effects as follows: the present invention is simple in structure, it passes through structural design cleverly, utilize air-flow to make material rotation at a high speed in equipment, and under action of centrifugal force, realize material layering, each stage material and impurity are separated by different outlets, especially realize approaching material and the separate impurities of physical dimension such as blade of grass, careless film, blade, improved blade screening quality; Secondly, specific yield power consumption of the present invention is low, can significantly reduce production costs.
