Definitions
- the present invention relates to an apparaus for dewatering and squeezing material in form of sludge, sediment, suspensions such as paper pulp, peat, etc.
- connection according to the invention makes it easier to optimize the operation over the apparatus. For instance, the output of the filter can be increased and thereby lower outgoing concentration from the filter be accepted and instead carried out a more powerful dewatering in the screw press part. In for instance machines placed apart from each other in the fabric such a balance in the operation is essentially more complicated to carry out and control.
- the feed screw is provided with a pin 31 which is journalled in bearing 32 in the press screw.
- a separate drive of the press screw takes place by means of a drive means 33.
- FIGs. 4a and 4b Another embodiment of the invention is shown in Figs. 4a and 4b.
- the dewatering device and the feed screw are provided with a sealing cap 34 whereby the apparatus can be operated under positive pressure and negative pressure, respectively.
- Such an arrangment makes the deposit and the dewatering of the material 22 on the sieve cloth 6 more effected.
- the guidence can, according to the above, function in such a way that the rotation speed of the feed screw is reduced when the power required for the feed screw increases and that the rotation speed returns to normal value when the power requirement again decreases.
- Required time delays for respective functions can be varied within the frame for the operation conditions.
- Such a guidance function is of course also possible to carry out in such a way that the rotation speed for the feed screw 8-10 is governed according to corresponding principles of the power requirement for the press part 29, 30.
