Summary of the invention
Technical problem to be solved by this invention is: provide a kind of suspension that makes along the feed arrangement in the equally distributed centrifugal discharging type centrifugal machine of rotary drum small end drum wall circumference.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the feed arrangement in the centrifugal discharging type centrifugal machine, comprise: casing, be provided with the main shaft of rotation in the casing, main shaft is provided with rotary drum, lateral sunken inside at the bottom of the rotary drum, form feed bin, the feed bin bottom be arranged on rotary drum at the bottom of same circumference on several evenly material paths of layouts communicate; The inwall of described casing is provided with the remittance hopper that matches with feed bin, and the hopper that converges is connected with some feed pipes in being located in casing.
Some above-mentioned feed pipes are that the center is located in the casing equably with the main shaft.
The invention has the beneficial effects as follows: because some material paths of feed bin are opened on the same circumference, the centrifugal force that suspension bears in this place is identical, enter the bottom of rotary drum small end simultaneously, and evenly distribute along the rotatory drum wall circumference, form the uniform circular filter cake layer at rotary drum small end inwall, make centrifuge turn round in the course of the work steadily, thereby guaranteed normally the carrying out of processes such as filtration, drying and discharging of centrifuge, significantly reduced the generation of mechanical breakdown.
