Detailed description of the invention
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As depicted in figs. 1 and 2, the horizontal centrifuge of band doctor blade device of the present invention, including rotating shaft 1,
The end of rotating shaft 1 is fixed with base plate 2, and edge one circle of base plate 2 is provided with rotary body 3, in rotary body 3
Portion is connected with base plate 2 and forms a material chamber 4 between the two, and axially disposed on the outer wall of rotary body 3 have spiral shell
Tooth 5, is enclosed with rotary drum 6 outside rotary body 3, on the wall in the middle part of rotary body 3 peripherally disposed have some
Through hole 7 outside connection material chamber 4 and rotary body 3, the head of rotary body 3 connects has connection rotary body 3 internal
Discharge bucket 8, discharge bucket 8 vertically places, and the discharging opening 9 of discharge bucket 8 is positioned at lower end, described discharge bucket 8
Upper end be provided with feed pipe 10, the upper end of feed pipe 10 protrudes upward discharge bucket 8, feed pipe 10 times
End stretches into and horizontally extends into material chamber 4 in discharge bucket 8 after bending again, and feed pipe 10 stretches into that end port in material chamber 4
In bell mouth shape and it is provided with the deflector 11 of hemisphere planar, deflector 11 and feed pipe 10 inwall in this end
Between be connected by reinforcement 12, form one between deflector 11 and feed pipe 10 in trumpet-shaped passage
13, the through hole 7 on the Way out alignment rotary body 3 of passage 13.The outlet of feed pipe is arranged to loudspeaker
Mouth shape, so making material is divergent shape when ejection, reduces flow velocity, and can be direct after aligned through holes
Enter rotary drum, avoid backflow situation to occur the most to greatest extent
The middle part of described rotary body 3 is round table-like, and head and afterbody are cylindrical and be horizontally disposed with, head
Diameter is less than the diameter of afterbody, and in the middle part of rotary body 3, the top inner wall of round platform is provided with an intilted gear of circle
Plate 14, so can prevent material from entering rotary body 3 head from material chamber 4 further.
It is covered with on the wall of described rotary body 3 head and has its inside and outside washing hole 15 of connection, feed pipe 10
Being provided with sluicing pipe 16 on outer wall, discharge bucket 8 is stretched out in one end of sluicing pipe 16, and the other end stretches into rotary body 3
Head is interior and this end is provided with some outlets 17, and material so can carry out the cleaning of necessity.
Described rotary drum 6 is outside equipped with case 18, rotary drum 6 is provided with within its inside of connection and case 18
Liquid outlet 19, rotary drum 6 near there being gap between that end end and case 18 edge of discharge bucket 8, and should between
Being provided with labyrinth type sealing ring 20 in gap, rotary drum 6 is provided with scraper 21, discharging near that end of discharge bucket 8
Struggling against and be provided with the collet 22 coordinated with scraper 21 on 8 inwalls, the projection in gap is positioned at collet 22,
The bottom of collet 22 is provided with gap 23.Actually used when, isolated liquid can be from rotary drum 6
Enter case 18, have a small amount of liquid simultaneously from the gap at labyrinth type sealing ring 20 place, penetrate into discharge bucket 8,
So out enter the solid material of discharge bucket 8 from rotary body 3 head once to touch this partially liq and will be formed
One pellet round and round, so can reduce the solid-liquid separation effect of centrifuge, is using scraper 21 and collet 22
After, these doughs will be bonded on collet 22, and then dough can be smashed under high speed rotating by scraper 21,
Thus ensure there is no dough from discharge bucket 8 solid material out, it is ensured that product quality.
As it is shown on figure 3, described gap 23 is positioned at a sidepiece of collet 22, wherein one end of gap 23
Being positioned on the horizontal diameter line of collet 22, the other end with the angle of collet 22 vertical direction diameter line is
