Description
Technical field
The utility model relates to centrifuge technique field, the rotary drum slag notch wear-resisting zero of specially a kind of decanter centrifuge
Part.
Background technique
Decanter centrifuge is in use, separates solids in suspension and liquid by centrifugal force, the institute after separation
There is solid to pass through the slag notch discharge that rotary drum small end is set.Since solid particle is making high speed rotary motion, make solid
Grain bears big thousands of times of force of gravity of centrifugal force, therefore can generate violent rub to slag notch inner wall when leaving rotary drum slag notch
It wipes, to generate serious wear phenomenon.All sediment particles all collect in above the side of slag notch, are then being centrifuged
Discharge centrifuge rotary drum under power and the collective effect of coriolis force.The rotary drum of existing decanter centrifuge, sediment thoroughly leave rotary drum
Position, distance of the sediment away from the centre of gyration is maximum, and suffered centrifugal force and coriolis force is also maximum, while sliding along slag notch
Speed is also maximum, therefore slag notch is the region for wearing most serious, and serious abrasion reduces the service life of decanter centrifuge, because
We make improvement to this for this, propose a kind of rotary drum slag notch wear part of decanter centrifuge.
Summary of the invention
It is the region for wearing most serious to solve the rotary drum slag notch of existing decanter centrifuge of the existing technology, sternly
The abrasion of weight reduces the defect of the service life of decanter centrifuge, and the rotary drum that the utility model provides a kind of decanter centrifuge is slagged tap
Mouth wear part.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of rotary drum slag notch wear part of decanter centrifuge of the utility model, including rotary drum, one end of the rotary drum
Equipped with connecting flange, the other end of the rotary drum is equipped with residue outlet, and the outer wall of the residue outlet is equipped with annular groove, the annular
The side of groove offers eight equally distributed slag notches, and the inside of eight slag notches is equipped with wear-resistant sleeve.
Further, the rotary drum is made of alloy material.
Further, the inner ring diameter of described rotary drum one end is less than the inner ring diameter of the rotary drum other end.
Further, the side of the connecting flange offers several equally distributed second fixed pin holes.
Further, trapezoidal groove is equipped at the top of the slag notch.
Further, one end of the residue outlet is equipped with several first fixed pin holes.
Compared with prior art, the utility model has the advantages that：The rotary drum slag notch of this kind of decanter centrifuge
The some materials that most severe region is worn on wear part are given removal by wear part, make the sliding for generating abrasion maximum
Speed and centrifugal force and coriolis force all accordingly becomes smaller, and improves the service life of wear part in this approach, while reducing resistance to
The weight of part is ground, energy consumption needed for maintaining centrifuge to operate is reduced.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, the rotary drum slag notch wear part of a kind of decanter centrifuge, including rotary drum 1, one end of rotary drum 1
Equipped with connecting flange 2, rotary drum 1 passes through connecting flange 2 with the big end axis of centrifuge through being fixedly connected, and the other end of rotary drum 1 is equipped with
The solid phase particles being deposited on drum inner wall are constantly scraped and are pushed away by residue outlet 5, the helical blade performed relative motion in rotary drum 1
It is sent to residue outlet 5 to be discharged from slag notch 4, the outer wall of residue outlet 5 is equipped with annular groove 3, reduces the weight of wear part, reduces
Energy consumption needed for maintaining centrifuge to operate, the side of annular groove 3 offers eight equally distributed slag notches 4, from 4 row of slag notch
Residue in rotary drum 1 out, the inside of eight slag notches 4 are equipped with wear-resistant sleeve 7, and wear-resistant sleeve 7 prevents residue and slag notch 4 from wearing,
Slag notch 4 is damaged, the service life of rotary drum 1 is reduced.
Wherein, one end of residue outlet 5 is equipped with several first fixed pin holes 6, and residue outlet 5 passes through several first fixed pins
The small end axis of hole 6 and centrifuge is through fixation.
Wherein, rotary drum 1 is made of alloy material, guarantees the intensity of rotary drum 1, guarantees the service life of centrifuge.
Wherein, the inner ring diameter of 1 one end of rotary drum is less than the inner ring diameter of 1 other end of rotary drum, presses the residue filtered out
Compel, squeezes out remaining supernatant in residue.
Wherein, the side of connecting flange 2 offers several equally distributed second fixed pin holes, and connecting flange 2 passes through
The big end axis of several second fixed pin holes and centrifuge is through being fixed.
Wherein, trapezoidal groove is equipped at the top of slag notch 4, trapezoidal groove is that removal the part worn occurs and formed recessed
Slot reduces abrasion of the residue to rotary drum 1.
It should be noted that the utility model is a kind of rotary drum slag notch wear part of decanter centrifuge, specific works
When, rotary drum 1 passes through connecting flange 2 with the big end axis of centrifuge through being fixedly connected, and connecting flange 2 passes through several second fixed pins
