Problems solved by technology

[0007] The disadvantage is that at any point in the outer perforated casing the nozzle tries to suppress the pressure in the entire casing in front of the nozzle
Suction efficiency decreases with distance from the nozzle, but ineffective suction at a distance deprives the suction zone near the powered nozzle

Embodiment Construction

[0037] In the figures, a pipe-in-pipe slurry removal device 10 for periodically removing slurry from a pit 11 with a cover 12 is provided. The slurry removal device 10 includes a built-in or installed collecting pipe 13, and a HDPE suction pipe 15 capable of feeding into the installed collecting pipe 13, wherein the collecting pipe 13 has holes 14 of Φ50 mm spaced uniformly at 1000 mm centers along it . The suction duct 15 terminates in a suction assembly 16 comprising a front spindle 17 having an axial equalization port 20 and spaced and secured from a tail spindle 21 by a stainless steel rod 18 . The tail spindle 21 has an axial bore 19 providing a connection to the suction duct 15 and the spindles 17, 21 define between them a suction zone 22 of length 940 mm.

[0038]The current ingots 17 pass through the respective apertures 14 in the collecting pipe 13 on the part arranged on the bottom of the covered slurry pit 11 , the suction zones 22 concentrating the suction at the ...

Abstract

There is provided sludge extraction apparatus (10) including a collection pipe (13) having a plurality of spaced, a suction pump (23), a suction pipe (15) with an end connected to the suction pump (23) and a suction head assembly (16) connected to the other end and slidable through the collection pipe (13) from an end, the suction head assembly (16) including a leading body portion (17) spaced from and connected to a trailing body portion (21) having an axial bore (19) connected to a suction pipe (15), the leading (17) and trailing (21) body portions substantially occluding the collection pipe (13) in use and defining there between a suction zone (22) of a length selected to open to at least one said opening at selected positions of the suction head assembly along the collection pipe.

Description

technical field [0001] The present invention relates to a slurry extraction device and method. [0002] The present invention has specific but not exclusive application to a slurry extraction apparatus and method for extracting slurry from spent palm oil settling ponds, and reference will be made to these applications for purposes of illustration. However, it should be understood that the invention may be used in other applications in general, such as slurry extraction from pits. Background technique [0003] None of the prior art described below constitutes common general knowledge in the art unless expressly indicated to the contrary. [0004] In conventional processes for extracting palm oil from palm oil kernels, a waste stream is produced, including water and fibers and other particulate organic material, dust and other minerals, filter cake, and the like. The effluent is piped to a lined or unlined open pit where it undergoes environmental degradation to generate CO ...
