Pipeline Macerators
Pipeline Macerators are designed to fit into the suction line of raw sewage or sludge pump, homogenizing the medium to improve downstream process, whilst protecting high performance pumps from tramp and rag debris in the medium. It is a disintegrating device for raw sewage and sludges up to 6% solid matter in a pipeline under operating conditions ranging from – 1 bar to + 4 bar. The range consists of a conditioning cutterhead co-axially mounted specifically designed to handle raw sewage and sludge. The cutters consist of a steel headstock with tungsten carbide wear blades rotating against a stationary alloy steel shearplate with a hardness of 50-55 HRC. The size of the holes in the shearplate may be specified to suit the application. The cutters can be replaced without disturbing the mechanical seal. The seal will rotate in an oil bath to ensure adequate cooling and lubrication which have a sealing rings of differing grades of tungsten carbide.
- lower running costs
- optimal cutting performance
- less power requirement
- higher performance
- fewer spare parts
- easier to maintain
- reduced downtime for routine servicing
For the process
- protection of the pump reliability
- creation of a pre-conditioned medium
Bio-Macerator:thorough disintegration and uniform blending of the liquid phase and cosubstrate into a homogeneous biomass substantially increases the efficiency of biogas production. Bellin has developed a compact unit specifically for this purpose. By combining a positive displacement pump (which may be rotary lobe pump or progressing cavity pump) and a powerful macerator into a single unit, Bio-Macerator can prepare superior quality biosuspensions. It can simultaneously feed one or more fermenters and handle additional pumping tasks in the biogas plant when needed. With cutting blades self-compensating, self-lubricated mechanical seal in oil bath, a large collecting container galvanized steel (stainless steel on request), settling out sump for stones and metallic objects, with special opening for easy inspection and cleaning.
