Description

A kind of multi-stage separation device

Technical field

The utility model relates to ball mill field, is the separator of ball mill specifically.

Background technology

Ball mill is widely used in the industrial circles such as coating, paint, rubber, abrasive material, pottery, ore, coal dust, metal dust, carbide alloy, magnetic material, food, daily use chemicals, dyestuff, ink, medicine, magnetic material, soft magnetic ferrite, photographic film. Existing grinder has the type such as dry type and wet type, the operation principle of wet ball mill is to adopt agitation grinding mode, when shaft High Rotation Speed, abrasive media and grinding charge (slip) that drive is called as " sand " do eddy motion, abrasive media is moved from bottom to top along inner tube wall under the effect of centrifugal force, while arriving liquid level, under the effect of self gravitation, redrop. In this process, abrasive media motion reciprocating extrusion, grinding, collision powder, then separate grinding material by separator with abrasive media, thereby play the effect of refinement material. But existing separator generally adopts clearance-type separator, its direct separation of material and abrasive media, not only separating effect is poor, and separative efficiency is lower.

Utility model content

For above-mentioned technical problem, the utility model provides a kind of multi-stage separation device that improves separative efficiency and effect.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of multi-stage separation device, comprise the horizontally disposed cylinder that one end is opened wide, this cylinder other end sealing, on the end face of this other end, offer discharging opening, described in cylinder, the other end is fixedly connected with rotating discharge axle, and described discharging opening is communicated with discharging axle inner chamber; Described in cylinder, one end inner chamber is coated with screen cloth, and cylinder other end inner chamber is installed with a separator, and the disengagement chamber of this separator is communicated with discharging opening; The material and the abrasive media that flow into from one end described in cylinder enter the centrifugation again of described separator after screen cloth pre-separation, and the material after again separating flows into discharging axle from disengagement chamber through discharging opening.

As preferably, described cylinder middle part is provided with dividing plate, one end described in cylinder and the other end are divided into two parts by this dividing plate, described one end is pre-subregion, the other end is Disengagement zone, on described dividing plate, open the through hole that is communicated with pre-subregion and Disengagement zone, described screen cloth is arranged on pre-subregion, and described separator is arranged on Disengagement zone.

As preferably, described separator one end is connected with dividing plate, and the other end is connected with other end end face described in cylinder, forms the separated space of ring-type between this separator outer wall and cylinder, and separated space is communicated with through hole.

As preferably, described separator is included in the rounded continuous netted extension in He Yugai outer ring, netted outer ring in cross section of cylinder radial direction, this extension in the cross section of cylinder radial direction in the shape of a spiral, the internal helicoid mouth of this helical form separator is disengagement chamber, and the material that enters separated space enters disengagement chamber from the mesh of separator outer ring and extension.

As preferably, on cylinder barrel corresponding to separated space, offer several return ports.

As preferably, be provided with several through holes at the barrel of one end described in cylinder.

As can be known from the above technical solutions, when material and the abrasive media of grinding chamber enter after the pre-subregion of cylinder, screen cloth can be blocked in pre-subregion by the material of abrasive media and larger particles, and can reflux from the through hole of barrel, thereby realize the pre-separation of material under the pre-abrasive media of subregion and the effect of the material of larger particles at rotary centrifugal force; More short grained material after pre-separation enters separated space, material in separated space is under the effect at centrifugal force, only have more short grained material to overcome the disengagement chamber that enters helical form separator under the effect of centrifugal force at grinding chamber pressure, thereby realize multi-stage separation, reach nano level separating effect.

Detailed description of the invention

Introduce in detail multi-stage separation device of the present utility model below in conjunction with Fig. 1, Fig. 2, comprise the horizontally disposed cylinder 1 that one end is opened wide, this cylinder other end sealing, on the end face of this other end, offer discharging opening 2, described in cylinder, the other end is fixedly connected with rotating discharge axle 8, discharging axle rotarily drives cylinder rotation, realizes Dynamic Separation, improves separative efficiency; Described discharging opening is communicated with discharging axle inner chamber; Described in cylinder, one end inner chamber is coated with screen cloth 9, and cylinder other end inner chamber is installed with a separator 4, and the disengagement chamber of this separator is communicated with discharging opening; The material and the abrasive media that flow into from one end described in cylinder enter the centrifugation again of described separator after screen cloth pre-separation, and the material after again separating flows into discharging axle from disengagement chamber through discharging opening, thereby realizes multi-stage separation.

As preferably, in the middle part of described cylinder, be provided with dividing plate 5, one end described in cylinder and the other end are divided into two parts by this dividing plate, and described one end is pre-subregion 6, and the other end is Disengagement zone 7, opens the through hole 51 that is communicated with pre-subregion and Disengagement zone on described dividing plate. When material and abrasive media enter after pre-subregion, through the material of screen cloth elimination abrasive media and larger particles, more short grained material enters Disengagement zone. In implementation process, the barrel of one end is provided with several through holes 3 described in cylinder, and under rotary centrifugal force effect, the material of abrasive media and larger particles is back to grinding chamber from through hole to be continued to grind; Because pre-subregion has carried out a pre-separation to abrasive media and grinding material, for further separating good material base is provided, thereby improve separating effect, can obtain nano level product.

In the utility model, described separator one end is connected with dividing plate 5, and the other end is connected with other end end face described in cylinder, forms the separated space 41 of ring-type between this separator outer wall and cylinder, and separated space is communicated with through hole 51. In pre-subregion, the more short grained material after screen cloth divides in advance enters Disengagement zone from through hole, and is looped around around separator, can further improve separative efficiency; As preferably, on cylinder barrel corresponding to separated space, offer several return ports 45, in separated space, can not overcome material that centrifugal force enters disengagement chamber and enter grinding chamber by return port and again participate in grinding.

The netted outer ring 42 that cross section that separator 4 of the present utility model is included in cylinder radial direction is rounded and with the continuous netted extension 43 in this outer ring, this extension in the cross section of cylinder radial direction in the shape of a spiral, the internal helicoid mouth of this helical form separator is disengagement chamber 44, a material part that enters separated space can overcome centrifugal force and enter disengagement chamber from the mesh of separator outer ring and extension, thereby realize centrifugation again, obtain the more product of small particle diameter.

Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from the utility model spirit and scope, can also make various variations and modification, therefore all technical schemes that are equal to also should belong to category of the present utility model.
