Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Embodiment: as shown in Figure 1, being a kind of wear-resisting easy-dismount decanter centrifuge disclosed by the invention, including rack 6, machine
Housing 7 is provided on frame 6, rotation is provided with rotary drum 8 and auger conveyor in housing 7, and auger conveyor is concentric to be set to
In rotary drum 8, and the two can control respectively rotation by being set to the alternating-current variable frequency motor 61 of 6 two sides of rack.On the right side of rack 6
It is fixedly installed feed pipe 9 by bracket 62, separation chamber 10 is formed between auger conveyor and rotary drum 8.
As shown in Fig. 2, auger conveyor includes the conveying blade 2 that centrifugation inner cylinder 1 and spiral are set to its lateral wall, from
Intracardiac cylinder 1 is made of stainless steel material, can be divided into three sections, is followed successively by connector drum 13, abrasion-resistant drum 12 and conical shell 11.
Connector drum 13 is cylindrical with abrasion-resistant drum 12, and the ring flange 4 welded by respective end therebetween is attached；It is resistance to
The one end of grinding cylinder 12 far from connector drum 13 can be welded with conical shell 11, also or flanged joint, in the present embodiment preferably
For welding.
As shown in Figure 1, the also tapered setting of the one end corresponding with conical shell 11 of rotary drum 8, and the conical section side wall of rotary drum 8
Offer discharging notch 81, while the bottom wall of housing 7 and with discharging notch 81 corresponding position offer solid phase outlet 71；
Offer the overflow port 82 being connected to separation chamber 10 far from one end of discharging notch 81 in rotary drum 8, at the same in the bottom wall of housing 7 and
Liquid phase outlet 72 is offered at position corresponding with overflow port 82.
As shown in figure 3, being detachably provided with the liner sleeve 3 being bonded with its inner sidewall, the neck bush in abrasion-resistant drum 12
Cylinder 3 is made of abrasive rubber material, is located at its lateral wall along its circumferential direction integrally formed with several strengthening rib strips 34, is located at its wall thickness
Several reinforcing rods 33 are inside circumferentially fixedly installed, one end of reinforcing rod 33 is pierced by liner sleeve 3 and is welded in same installation circle
On disk 32, the end face of the end face and liner sleeve 3 of installing disk 32 is fixed.In 4 inner edge of ring flange welded with abrasion-resistant drum 12
It is formed with installation step 41, the external profile diameter of installation step 41 is equal with installation 32 diameter of disk, liner sleeve 3 is sheathed on resistance to
After grinding cylinder 12, disk 32 will be installed by bolt 321 and installation step 41 is fixed.
As shown in figs. 1 and 3, one end of feed pipe 9 extends in liner sleeve 3, positioned at the liner sleeve of 9 nozzle of feed pipe
3 side walls offer interior discharge port 31 along its circumferential direction, while in the corresponding position of the side wall of abrasion-resistant drum 12 and interior discharge port 31
Offer outer discharge port 121.After entire centrifugation inner cylinder 1 and rotary drum 8 relatively rotate, feed liquid can be from interior discharge port 31 and outgoing
Material mouth 121 drains into rotary drum 8, and in the process, it is directly interior with abrasion-resistant drum 12 that liner sleeve 3 can avoid the solid phase in feed liquid
Side wall contact, it is also conveniently replaced when liner sleeve 3 wears more serious.If charging rate is too fast, lead to interior discharge port 31, outer
The discharging of discharge port 121 over-burden and when can not be discharged in time, in conical shell 11 close to the end sidewalls of abrasion-resistant drum 12
It is also provided with spare discharge port 111, can cooperate with interior discharge port 31, outer discharge port 121 jointly will be excessive in abrasion-resistant drum 12
Feed liquid discharge.
As shown in Figures 2 and 3, when specifically processing auger conveyor, first liner sleeve 3 is installed in abrasion-resistant drum 12, then
The ring flange 4 welded with connector drum 13 and abrasion-resistant drum 12 is aligned, and is equally fixed by bolt 321, finally again
Conveying blade 2 is welded in the surface of above-mentioned three, when welding need to avoid ring flange 4.But due to the spiral shell on elastic ring flange 4
When bolt 321, the conveying blade 2 at ring flange 4 can interfere the installation of bolt 321, therefore on the conveying blade 2 at this also
Future insufficiency 21 is offered, so that corresponding bolt 321 carries out disassembly and installs again.
As shown in figure 3, in order to further protect the not frayed of outer discharge port 121 and spare discharge port 111, in it
Portion is inlaid with wear-resistant pipe 5 made of wear-resistant ceramic material, but defeated on abrasion-resistant drum 12 and conical shell 11 with being welded in
Except sending the spare discharge port 111 and outer discharge port 121 that blade 2 is interfered.
The implementation principle of above-described embodiment are as follows: feed liquid can be acted on after feed pipe 9 conveys abrasion-resistant drum 12 by centrifugal force
It is expelled in rotary drum 8 from outer discharge port 121.Under effect of centrifugal force, heavier solid formation is deposited in separation chamber 10 and is formed
Sediment, and lighter liquid phase then floats on top, solid formation is continuously pushed into the conical section of rotary drum 8 by conveying blade 2 at this time
Place, solid formation can by the conical section side wall extruding and the liquid phase object contained inside it is extracted, finally from discharging 81 row of notch
Out in housing 7, and it is discharged from solid phase outlet 71.At the same time, when the liquid phase object of separation chamber 10 reaches 82 height of overflow port
When, the liquid phase object that overflow goes out can be discharged into housing 7 from liquid phase outlet 72, be finally discharged from liquid phase outlet 72, realize feed liquid
Separation of solid and liquid.
When liner sleeve 3, which is used for a long time, wears more serious, first unscrew the bolt 321 on ring flange 4, by abrasion-resistant drum
12 remove together with conical shell 11, then unscrew the bolt 321 on installation disk 32, take out liner sleeve 3 and use instead it is new i.e.
It can.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
