Jul 01, 1975· Thickener with elevatable scraper and non-elevating skimmer . United States Patent 3892666 . Abstract: A circular-tank gravity thickener having a central rotating feedwell is provided with a skimmer which is entirely supported by and rotates with the feedwell so that the rotating scraper mechanism may be elevated independently in a conventional ...
Lackeby gravity thickener scraper is designed with a gear box transmission, a vertical pipe shaft and supporting brackets for the thickening arms and the scraper blades. The shape and design of the shaft, the brackets and the scraper blades are designed to provide as high solids as possible.
scraper can even be equipped with hydrometers (also referred to as airlift pumps) or submersible pumps. Sludge thickener The sludge thickener in turn is intended to thicken the sedimentated sludge from the sedimentation tanks. A predetermined number of activation rods are welded in place in the arms. The arms are also equipped with bottom
2 Claims, 2 Drawing Figures THICKENER WITH ELEVATABLE SCRAPER AND NON-ELEVATING SKIMMER BACKGROUND OF THE INVENTION The prior art includes thickeners of the type shown in this application wherein the scraper mechanism is elevatable but no provision is made for skimming.
How a Thickener Works ... Scraper blades or rakes, driven by a suitable mechanism, rotating slowly over the bottom of the tank, which usually slopes gently toward the center, move the material settled on the bottom to a central opening or discharge. The rakes revolve at a speed sufficient to move the material as fast as it settles without ...
Sludge thickener FRC Sludgeway® equipment developed by Toro Equipment is designed to provide optimum treatment, reducing the concentration of solids in wastewater and increasing the sludge concentration. The sludge thickener is manufactured in GRP, AISI304 steel and PP.

The Ovivo ® spiral blade scraper clarifier is designed for municipal wastewater, municipal drinking water and industrial wastewater treatment applications. It features rapid sludge removal by the action of spiral raking blades. Maximizing sludge concentration, providing low effluent suspended solids and efficient scum removal, this clarifier model is well adapted for primary and secondary ...
The Z2000 Bottom Sludge Scraper is designed to provide continuous sludge transportation and performs well in all sedimentation processes, even in a sand trap. The Z2000 can be adapted to the most varied requirements because it is not dependent on where the operation is located and there is a choice between a hydraulic drive and an electric motor.
The supporting modes of the center transmission thickening scraper includes center transmission with middle hanger and the center transmission with the peripheral hangers. The former one with the scraper hanging on the truss frame and packeted bridge structure, simple installation, is mainly for thickener …
Chemical floculants and coagulents can greatly improve the performance of most thickeners. The animated graphic at right shows the rotation of the rake mechanism in a thickener. The rakes slowly rotate, with scraper blades on the bottom, pushing solids in the thickener towards the cone shaped discharge located in the center of the thickener.
Thickeners, equipped with the patented spiral scrapers and angle rakes are a distinct improvement over all types of mechanical raking devices now in use. Specifications and thickener rake design. All Thickeners have the same general specifications, varying only as to type of machine. The specifications given for one will cover all.
Thickeners Scrapers by SISMAT ULUSLARARASI LTD. STI.. Similarly to circular scrapers, they can be designed with a fixed bridge or a rotating bridge. They are equipped with bars placed within the basin to help accelerate the settling of solids.
Apr 19, 2017· Rota-Rake® Thickener The Graver Rota-Rake® Thickener is a horizontal flow sedimentation and thickening unit for the efficient separation of suspended solids from liquids by gravity. Designed for maximum separation, positive sludge removal and complete overload protection, the Rota-Rake consists of: 1.
high loaded static thickener. In some cases, it is not advisable to look for a high level of thickening (e.g. direct dewatering using centrifugation, in order to reduce machine size - see high pressure centrifuges). Dimensioning is then calculated with reference to the first part of …
We also have led the way in developing paste thickening technology, with more paste thickening installations than all of our competitors combined. All of the durable and productive thickening and clarifying equipment we offer is among the most technologically advanced and rigorously tested products available on the market today.
Monroe Environmental designs and manufactures primary and secondary circular clarifiers for industrial and municipal wastewater treatment, as well as flocculating clarifiers and solids contact clarifiers for clean water or potable water applications.
Straight plough scrapers were popular but not effective for any type of solids. Curved plough scrapers are convenient at many situations. Fixing them to the arm is relatively complicated and thus spiral scrapers took over. Variable angle spiral scrapers are popular in Europe.
3. Positive slude collection and discharge system including motor-driven scraper and conical central discharge sump in the bottom of the tank. The Rota-Rake is available in a wide range of sizes and designs to fit the needs of every type of gravity separation application. Advantages of the Rota-Rake ® Thickener
Scraper & Picket Fence Thickener Equipment. Circular Settling Tank Equipment. Tuke and Bell offer a complete range of rotary scrapers for primary and secondary settling tanks, for sewage works and water treatment plants. The range is manufactured to standard designs but can be specially adapted to suit individual requirements.
Gravity thickening uses the natural tendency of higher-density solids to settle out of liquid to concentrate the solids. Gravity thickeners consist of a circular tank (usually with a conical bottom) that is fitted with collectors or scrapers at the bottom.
The Cone Scraper . Underflow Pumping. Pumping of dense underflows has always been a problem on thickeners that handle slurries such as metallurgical concentrates, potash or phosphate and the position of the pumps in relation to the discharge cone can be very critical.
