Definitions
- the invention relates to a method for adjusting the liquid content of a self-emptying centrifugal drum
- the solid discharged from self-emptying centrifugal drums has the highest possible dry matter content. In these cases, it must be avoided that the solid escapes when the solids are ejected from the centrifugal drum. In order to achieve this, so-called "partial emptying" is used, in which the centrifugal drum is only opened for such a short time that most of the solids can escape.
- the invention has for its object to design a method and a device of the type mentioned in such a way that the consistency-determining liquid content can be set before the solid is discharged from the centrifugal drum.
- this object is achieved in that the separator is brought to a standstill before the solid is emptied from the centrifugal drum, the liquid remaining in the interior of the centrifugal drum except for one of the the required residual consistency of the solid is suctioned off and then the centrifugal drum is emptied at a suitable speed.
- Mixing inlet pipe provided for the centrifugal drum is used, which can be adjusted in height and extends in the lower end position up to the vicinity of the drum base.
- the free end can be moved to the lowest point of the drum base, so that the liquid is almost completely shut off by the inlet pipe
- Inlet can be suctioned off. Furthermore, a remaining amount of residual liquid can be set via the set distance of the lower opening of the inlet pipe to the drum base and thus influence the consistency of the discharged solid.
- Solid-liquid mixture as a suction tube results in a simple construction for carrying out the suction operation in order to draw off a desired amount of liquid from the inside of the centrifugal drum.
- inlet pipe as a suction pipe is possible both with stationary and with rotating inlet pipes.
- the centrifugal drum 1 is composed of the lower part 2, the upper part 3 and a connecting ring 4.
- a piston slide 5 is slidably mounted and closes in the operating position shown on the Discharge openings 6 arranged around the circumference for the solid which collects in the solid space 7 during operation of the separator.
- the centrifugal drum also has a separation space 8, in which a plate pack is arranged.
- the solid-liquid mixture is fed through an inlet pipe
- shut-off device 1 9
- shut-off device 1 0 branches off from the inlet pipe 9, a nozzle 1 1, in which a shut-off valve 1 2 is arranged and which is connected to a suction device, not shown.
- the inlet pipe 9 can be adjusted in the axial direction, by means of an adjusting device 1 3, which is only indicated in the drawing.
- the bottom of the centrifugal drum is composed of an annular surface 1 4 of the piston slide 5 and an annular surface 1 5 of the lower part 2. From the illustration it follows that the surfaces 1 4 and 1 5 to the center 1 6 inwards and downwards, that is to say with a slope, so that when the
- Centrifugal drum collects the residual liquid in the central lower area of the centrifugal drum.
- the distance between the lower opening 1 7 of the inlet tube 9, which sometimes acts as a suction tube, can be set exactly, so that the amount of liquid remaining in the centrifugal drum and released after restarting the separator is determined
- Discharge openings 6 is discharged together with the solid.
