Decantador filtrante CONTHICK
Decantador filtrante CONTHICK
Separación eficiente con espesamiento previo.
El decantador con filtrado SIEBTECHNIK CONTHICK es una máquina combinada que consiste en un tambor ciego en la zona de alimentación del producto y un tambor con filtración instalado corriente abajo.
Los materiales sólidos se separan por sedimentación en el tambor ciego y se espesan. El producto puede ser lavado y deshidratado hasta el límite de desaguado mediante separación mecánica. Otra característica especial del CONTHICK es su montaje en voladizo. Este diseño permite una fácil limpieza y un rápido acceso a las partes en contacto con el producto. Como resultado, los costos de mantenimiento y los tiempos de mantenimiento se reducen considerablemente.
La segunda corriente de líquido se drena a través de un conducto de drenaje separado.
Todas las centrífugas CONTHICK están adaptadas individualmente para adaptarse a las condiciones del producto y los requerimientos del sistema.
Comportamiento operacional y características mecánicas.
El diseño de esta centrífuga se basa en la tecnología de nuestra centrífuga de husillo sin fin de filtrado CONTURBEX con la adición de una etapa de espesamiento previo. El objetivo es una alta eficiencia de separación, incluso con suspensiones con bajas concentraciones y un alto contenido de finos.
La tarea que debe realizar esta centrífuga consiste en la separación de la materia sólida y los líquidos de las suspensiones. La suspensión se alimenta a la etapa de espesamiento previo de la centrífuga a través de un tubo de entrada y aberturas en el centro del cuerpo del husillo.
El contenido de líquido principal se drena a través de una trampilla ajustable en la parte posterior del tambor ciego para obtener un filtrado claro.
La materia sólida se espesa previamente y se transporta desde el husillo a la sección de filtrado, donde se realiza el desaguado residual y, si es necesario, el lavado del producto. Las corrientes de líquido del tambor ciego y la sección de filtrado se drenan opcionalmente de forma individual o conjunta mediante un separador de ciclón simple o doble.
La pérdida de material sólido es relativamente pequeña y puede reducirse aún más devolviendo el líquido de filtrado a la alimentación. La materia sólida es transportada por el husillo a la carcasa de descarga de sólidos a través de la sección cilíndrica.
La centrífuga está equipada con una rejilla ranurada de perfil especial. Dependiendo de la aplicación, se puede usar alternativamente una chapa perforada especial. En todos los casos, los elementos de cribado pueden intercambiarse muy fácilmente sin tener que desmontar la máquina o las piezas giratorias.
Drives for centrifuges
The solution to a separation task depends very decisively on the centrifuge drive. The centrifugal force required for solid-liquid separation is determined by the bowl or screen speed. To achieve the right speed for optimum separating results, it is frequently necessary to keep the speeds variable. The drive control needed for this is designed by our specialists specifically to fit your application.
Furthermore, on screen worm centrifuges and in decanters the speed differential between the solid-conveying worm and the bowl is decisive. It determines the time which the solid spends in the centrifuge and so the quality of the drying. The correct speed differential for your separation task is determined by the correct choice of gear unit. The speed differential here may be constant, but may also be variable. In the latter case the back-drive, where the otherwise fixed gear input shaft is also driven, is used. If the worm speed is required to be kept completely independent of the drum speed, hydraulic drives (viscotherms) or two-stage gear units with an upstream differential planetary stage are used.
To guarantee the operational reliability of your centrifuge, the drive system is continuously monitored. Excessive speeds, overcurrent and slip are identified and reported to the machine control system and there processed.
Only a drive system specially designed for your separating task will give optimum separating results.
Explosion protection / inertising
Explosion protection/inertising
Inertisation of our machines and systems may be necessary for various reasons. In many industrial processes it is necessary for safety reasons to reliably prevent the build-up of an explosive atmosphere through dust or gases (ATEX).
It may also be necessary to seal and overlay the product spaces with inert gas, e.g. nitrogen (N2) or carbon dioxide (CO2), to prevent oxidation and maintain product quality.
Use SIEBTECHNIK specialialists’ many decades of experience in all areas of industry to help seal and inertise the process spaces in your centrifuges.
We will be pleased to work with our customers to draw up an inertising concept for the integration of our machines into existing or scheduled plant systems.
Hygienic Design / CIP
The name SIEBTECHNIK is inseparably associated with dewatering tasks to meet the most stringent hygiene requirements. The separation of batter from frying oil at temperatures of approx. 200°C with the SHORTBOWL decanter centrifuge, the centrifuging of lactose crystals with the SHORTBOWL decanter centrifuge and the CONTURBEX screen worm centrifuge for the manufacture of baby food or the manufacture of extremely pure inorganic salts with our CONTURBEX and pusher centrifuges are some examples. Design features for this are the technical separation of the drive and processing sections of the centrifuge and highly developed sealing systems that are easy to clean by CIP.
For the optimisation of centrifuges in the hygiene sector and/or in areas where e.g. cross-contamination has to be prevented by CIP we use riboflavin tests to examine and optimise cleaning results.
Our self-developed and USDA-certified CIP nozzles, self-developed hygienic screw connections, special hygiene surfaces or our highly developed USDA-conformant sealing technology make many dewatering tasks possible only with our centriguges.

System solutions
SIEBTECHNIK TEMA has consistently developed itself into one of the world’s most innovative manufacturer of continuous centrifuges and suppliers of system solutions in the field of mechanical and thermal solid-liquid separation since the early 1940s. SIEBTECHNIK/TEMA is your reliable partner for customer-focused, custom-built machines and system solutions.
SIEBTECHNIK TEMA centrifuge and drier systems offer you the latest technology, customer- and product-specific special fittings and individual consultation at the pre-sales stage and reliable support in the after-sales process. For mechanical liquid separation continuously operating centrifuges are often the technically and economically best solution. They separate large volumes in closed housings with little space requirement and low energy and time costs. Also drying on the fluidised bed with fluidised bed driers and coolers has established itself in numerous branches of industry and applications.
