Abstract
The utility model relates to a horizontal decanter centrifuge nozzle assembly comprising a nozzle seat, a nozzle tube and a nozzle. The nozzle seat is in an annular structure with the cross section in an internal L shape, and a circle of groove is formed in the center inside the annular structure. The outside of the annular structure of the nozzle seat, adjacent to one end of the internal L shape perpendicular to the central line of the nozzle tube is provided with a screwed hole used for fixedly connecting the nozzle seat and a decanter centrifuge drum. The nozzle assembly is applied to a horizontal decanter centrifuge applied to the kaolin classification industry. By adopting the structure, an certain included angle is formed between the spraying direction of the kaolin underflow slurry from the nozzle and the direction of the fixed drum external diameter tangent, and the kaolin is prevented from wearing the outer edge of the drum; meanwhile, the kaolin slurry classification effect is better, processing quantity is increased, and the nozzle assembly can be mounted, demounted and maintained more conveniently and has high practicality.
Description
Technical field
The utility model relates to Kaolin classification special horizontal sedimentation centrifuge technical field, relates in particular to a kind of Horizontal sedimentation centrifuge nozzle assembly.
Background technology
Kaolin slurry in Horizontal sedimentation centrifuge underflow slurries after sedimentation under centrifugal action are discharged by nozzle, and overflow slurry is discharged by the spout hole of rotary drum one end.Horizontal sedimentation bowl surrounding is provided with a plurality of uniform nozzles, in actual use can be according to the solid content of material, classification requirement etc., and the quantity of capable of regulating nozzle, the size of nozzle meet different separating effects.But at present nozzle assembly structural design used is not too reasonable, to install, dismounting, safeguard very inconveniently, the weak effect of classification kaolin slurry is installed unreasonablely simultaneously, causes rotary drum to put forward outer rim serious wear.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of long service life, treating capacity is large, grading effect is good Horizontal sedimentation centrifuge nozzle assembly are provided.
In order to solve above technical problem, the utility model provides a kind of Horizontal sedimentation centrifuge nozzle assembly, comprises nozzle carrier, blast tube and nozzle.
Described nozzle carrier is that cross section is interior L shaped loop configuration, and loop configuration bosom position is provided with a circle groove.
In order to prevent in rotary drum body work rotary course, internal pressure is crossed can eject jet hole by nozzle assembly, in described nozzle carrier annular structural outer, near interior L shaped one end, perpendicular to the position of described blast tube center line, is provided with the screwed hole that described nozzle carrier is fixedly connected with bowl.
In addition, because rotary drum body is High Rotation Speed in the course of the work, underflow slurries when nozzle sprays due to its emission direction of centrifugal action and rotary drum body edge tangential direction always, if vertical design is installed nozzle, the underflow slurries wearing and tearing that rotary drum body outer rim of long duration is ejected, greatly shorten service life.In order to prevent that the outer rim of rotary drum body is worn, during installation, nozzle assembly and rotary drum body external diameter tangential direction form the angle of 10 ゜-18 ゜.
It is inner near interior L shaped one end that described nozzle is arranged on described nozzle carrier.
Described blast tube one end is that cross section is outer L shaped loop configuration, and it is inner that described blast tube is arranged on described nozzle carrier, and outer L shaped one end is stuck in the groove of described nozzle carrier and is connected with described nozzle.
The technical scheme that the utility model further limits is:
Further, described blast tube is external thread structure, and the other end of the L shaped shape of described nozzle carrier is female thread structure.
Further, the utility model also comprises nozzle nut, and described nozzle nut is for locking the external thread structure of described blast tube and described nozzle carrier.
Further, for described nozzle carrier and bowl body are tightly meshed, described nozzle carrier outside is also provided with the annular groove of mounting O-shaped sealing ring.
Further, the screwed hole on described nozzle carrier is fixedly connected with bowl body by hex bolts.
The beneficial effects of the utility model are: nozzle assembly described in the utility model is applied on Horizontal sedimentation centrifuge, and this type has been successfully applied to Kaolin classification industry.This structure can make kaolin underflow slurries have certain angle from the direction rotary drum external diameter tangential direction fixing with it of jet hole ejection, prevents kaolin wearing and tearing rotary drum outer rim.Meanwhile, the application of this structure makes the better effects if of classification kaolin slurry, and treating capacity is larger.And install, dismantle, safeguard more convenient, there is very strong practicality.
Accompanying drawing explanation
Fig. 1 is the utility model structure transverse sectional view.
Fig. 2 is that the utility model is arranged on the structural representation in rotary drum body.
The specific embodiment
embodiment 1
A kind of Horizontal sedimentation centrifuge nozzle assembly that the present embodiment provides, as shown in Figure 1, 2: comprise nozzle carrier 3, blast tube 2, nozzle 1, O RunddichtringO 4 and nozzle nut 5.
Nozzle carrier 3 for cross section be interior L shaped loop configuration, loop configuration bosom position is provided with a circle groove.
The outside close interior L shaped one end of nozzle carrier 3 loop configuration is provided with perpendicular to the position of blast tube 2 center lines the screwed hole 6 that nozzle carrier 3 is fixedly connected with bowl.Blast tube 2 one end are that cross section is outer L shaped loop configuration, and the other end is external thread structure, and the other end of nozzle carrier 3L shape is female thread structure.
Nozzle nut 5 is for locking the external thread structure of blast tube 2 and nozzle carrier 3.
During installation, it is inner near interior L shaped one end that nozzle 1 is arranged on nozzle carrier 3; Blast tube 2 is arranged on nozzle carrier 3 inside, and the outer L shaped one end of blast tube 2 is stuck in the groove of nozzle carrier 3 and is connected with nozzle 1.Screwed hole 6 on nozzle carrier 3 is fixedly connected with bowl body by hex bolts.Nozzle assembly and rotary drum body external diameter tangential direction form the angle of 10 ゜-18 ゜.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
