When the centrifugal machine works, the magnetic particles are speeded up to settle on the inner wall of the rotating drum under the combined action of the double pushing force of the centrifugal force and the attraction force of a magnetic field, and the magnetic particles in a solid phase can be delivered to a slag discharging port through a screw. As a result, solid phase and liquid phases in the suspension liquid are separated effectively. The utility model is especially suitable for the centrifugal sedimentation and separation of suspension liquid containing ultrafine magnetic particles.
Description
The utility model relates to a kind of compound action of centrifugal force and magnetic force of utilizing and separates the horizontal spiral discharge sedimentation centrifuge that contains superfine magnetic particle suspension.
Before the application finishes,, adopt natural sedimentation to carry out Separation of Solid and Liquid usually for the suspension that contains superfine magnetic particle.This method deficiency be that particle velocity is slow, inferior separating effect, floor space is big, the water capacity of gained sedimentation underflow is big.Filtering separation devices such as employing plate and frame filter press carry out Separation of Solid and Liquid, and operator's labour intensity is big, can not realize the totally-enclosed operation, because superfine particle easily blocks filter cloth, need carry out frequent regeneration to filter cloth, very trouble.Adopt the horizontal spiral discharge sedimentation centrifuge of prior art to separate this class suspension, though avoided the shortcoming of above-mentioned separation equipment, but because this machine is in separation process, centrifugal force is unique motive force of solids sedimentation, therefore the suspension that contains superfine magnetic particle is effectively separated, need under high rotating speed, carry out, so just bring the energy consumption height, the problem that wear and tear in machines is serious.
The design the purpose of this utility model is to provide a kind of under centrifugal force and the dual impetus of magnetic force, and the suspension that contains superfine magnetic particle is carried out the horizontal spiral discharge sedimentation centrifuge that automatic continuous sedimentation is separated.
Realize that the centrifugal force of the utility model above-mentioned purpose and the horizontal screw centrifuge of magnetic force compound action include rotary drum, with the rotary drum coaxial line be installed in discharge auger in the rotary drum, make the equidirectional rotation of spiral and rotary drum and the differential mechanism of certain speed discrepancy is arranged, suspension is introduced the feed pipe that separates in the rotary drum, be arranged on the magnetic means that on the rotary drum body magnetic force is put on magnetic particle in the rotary drum settling section scope inner suspension liquid, and be arranged on the slag notch of rotary drum small end and the overfall of the big end of rotary drum.The solid that is deposited on the rotary drum body inwall is transported to the slag notch that is arranged on the rotary drum small end under the effect of difference rotating speed, liquid is then discharged from the overfall that is arranged on the big end of rotary drum by the helical duct that helical blade and rotary drum body inwall constitute.
The magnetic means that is arranged on the rotary drum body can be an electromagnetic force arrangement, also can be the permanent magnet magnetic power apparatus.When magnetic means was electromagnetic force arrangement, electromagnetic force arrangement was made of magnetisable steel rotary drum body of making and the coil that is wrapped on its outside wall surface.When magnetic means was the permanent magnet magnetic power apparatus, the permanent magnet magnetic power apparatus can be that the rotary drum body by the permanent-magnet material manufacturing constitutes, and the inside and outside wall of cylindrical shell is respectively the two poles of the earth, north and south in magnetic field.The permanent magnet magnetic power apparatus also can be made of the permanent-magnet pieces that evenly is arranged on the rotary drum body, and permanent-magnet pieces is respectively the two poles of the earth, north and south of permanent-magnet pieces along two faces of cylindrical shell radial direction.Permanent-magnet pieces can be a strip, also can be annular.When being strip, permanent-magnet pieces evenly is embedded on the internal face of cylindrical shell along the generatrix direction of cylindrical shell.When it was annular shape, permanent-magnet pieces was embedded on the internal face of cylindrical shell equably along the circumferential direction of cylindrical shell.When the suspension of centrifuge separation is corrosive to permanent-magnet material, avoid the corrosion of suspension in order to protect permanent-magnet material, can on the internal face of rotary drum body, corrosion protective covering be set.
Permanent-magnet material can be the magnet steel of magnetic ceramics, neodymium iron boron, aluminium nickel or other kinds that suitable magnetic induction is arranged.
Rotary drum body can be the combined barrel of cylindrical tube and conic tube, can all be conic tube also.The profile of discharge auger and the shape of rotary drum body match, and spiral is installed in the rotary drum body, between the outer rim of spiral and the rotary drum body internal face certain clearance are arranged.
Be provided with the overflow baffle of adjusting centrifuge dewatering district and decanting zone length at the big end overfall of rotary drum place,, make it to reach the optimal separation effect to adapt to suspension of different nature.
The utility model has also been taked other some technical measures.
Technological core of the present utility model is on the basis of the horizontal spiral discharge sedimentation centrifuge of prior art, on the bowl cylindrical shell, set up magnetic means, make magnetic particle in the suspension in the rotary drum body under the compound action of centrifugal force and magnetic force, to the rapid sedimentation of rotary drum body inwall.The most outstanding advantage of the utility model is that centrifuge speed is not under the very high situation, just the superfine magnetic particle that is difficult in the suspension separate can be separated rapidly.The utility model is compared with traditional natural subsidence solid-liquid isolation method, and separating rate is fast, and the sediment water capacity is low, good separating effect, and floor space is little.Compare with filter such as plate and frame filter press, the Separation of Solid and Liquid overall process all is to carry out continuously automatically in airtight fully machine, need not filter cloth, has also save the regenerative process of filter cloth, has exempted operator's strong physical work, and good separating effect.Compare with the horizontal screw unloading centrifuge of prior art, under the situation that superfine magnetic particle granularity is identical in the suspension, machine run speed reduces greatly, avoided because the energy consumption height that the machine rotational speed height causes, wear and tear in machines is serious, and maintenance is changed frequent, machine run parts design requirement on machining accuracy height, make difficulty, problems such as machine cost height.
Of the present utility model open, for providing a kind of, people dexterously centrifugal force is combined with magnetic force, be used to separate the suspension that contains superfine magnetic particle, and the novel horizontal spiral discharge sedimentation centrifuge that other separation equipments are difficult to be competent at, and disposal ability is big, good separating effect, function admirable.
