SOLIDS DRAG MECHANISMS > Chain Scraper
INTRODUCTION:
The CP-6 chain scraper manufactured by FILTRAMAS is the result of an extensive experience in this type of system developed in the United States and widely used in the European Nordic countries. The chain scraper can be used for bottom sweeping, surface sweeping or both, always made of corrosion-resistant materials.
DESCRIPTION:
The chain sweeper consists of the following elements:
-
A coaxial gearmotor unit, with high transmission efficiency, installed on a tensioning bed and protected by a chainguard.
-
Drive chain: It can be made of plastic links with stainless steel shaft or completely made of stainless steel, depending on the power. Its mission is to transmit movement to the sweeper’s drive shaft.
-
Drive shaft: Consists of a stainless steel tube to which the rim for the drag chains are attached. It has two stumps at its ends which are inserted into two DUROGLISS bushings. The rim is installed on one side of the shaft, where the transmission chain operates.
-
Driven axles: Up to three driven axles can be installed depending on the scraper configuration and application. One of them is equipped with a chain tensioning system. They are made of stainless steel and are mounted on DUROGLISS bushings.
-
Transmission Rim: Drive Rims are manufactured in ST-52, AISI-304 and AISI-316, and the driven ones in high molecular weight polyethylene.
-
Conveyor chain: ROTARY type, with angled link and made of corrosion-resistant plastic material. The links are made of glass-fibre reinforced acetal resin and the shafts are made of PBT. The breaking load is approximately 20 KN. The chain incorporates several couplings, depending on the design, for the assembly of the sweeping scrapers.
-
Sweeping scrapers: They form an U of 180x80mm, built in GRP with white gel coat finish. The maximum permissible span is 6 m.
-
Sufferers: Provide a sliding surface for fiberglass protection. Made of plastic material.
-
Sliding guides: The scrapers slide on stainless steel or polyethylene guides placed in the civil works. They prevent excessive buckling in the return or ensure the sweeping of the floats, as the case may be. The bottom guides are embedded in the concrete.
-
Screws: All screws used are made of AISI-304 or AISI-316 stainless steel, with self-locking nuts.
GENERAL DIMENSIONS:
FILTRAMAS has four different models depending on the application:
1. Two-axis bottom scraper: Mainly used in the case of superior occupancy by means of lamellas. The chain tension and system check must be carried out by emptying the tank during maintenance stops.
2. Three-axis bottom scraper: The chain tension and system check can be carried out from the upper area, as the scrapers reach the surface of the tank.
3. Four-axis system with bottom and floating scraper: The removal of the floats is carried out by means of a rotating sensor.
4. Two-axis system with floating scraper: The removal of the floats is carried out by means of a rotating sensor or by means of a ramp.

The accumulation of solid waste in water treatment requires effective mechanized solutions for its extraction. FILTRAMAS, S.A. has a wide variety of equipment for the dragging of solid waste.
Band screens are those equipments, installed in a channel or , which has a series of filtering surfaces in continuous movement. Its mission is to extract the suspended solids of a certain size that accompany the effluent. There are several types of band screens, depending on the characteristics of the effluent and the installation:
The objective of this equipment is to protect the WWTP or pumping well from the possible arrival of large objects capable of causing obstructions in the different units of the installation. This operation consists of passing the waste water through a screen that separates and evacuates the bulky materials dragged along. They will retain large-sized solids such as branches, leaves, paper, tree roots, plastics, wipes, rags, etc., preventing damage and blockages to pumps, valves, pipes and other elements present in subsequent treatment processes of the purification plant.
These devices allow to continue filtering while performing self-cleaning, being especially suitable for those applications where continuous filtering is an important parameter of the process. Filtramas recommends the installation of its FB or FW in-line filters according to the flow and filtration needs.
Filter sieves offer high performance in the solid-liquid separation process. Our range of equipment responds to the different possible needs for each case.
FILTRAMAS, S.A. has a wide range of solutions for the transport and compacting of the waste extracted by its machines, in a clean and discreet. The conveying and compacting systems can be with screws with final draining zone or hydraulic presses.
The conveyor-compactor screws supplied by FILTRAMAS, S.A., coupled together with its equipment, allow us to obtain a totally clean and fair-faced installation. The screw loading openings are designed for coupling to the discharge opening of the extraction equipment (bars movable grilles or screens), and the intermediate spaces are covered by a fairing.
In any water treatment or purification plant, there is a continuous need to isolate or regulate the flow of water in the channels and manholes or holes in walls (wall gates). This function is carried out by means of the placement of gates and cofferdams.
The result of our experience is the establishment of a standardization that determines a satisfactory result with a simple construction. For this reason, Filtramas has been developing the manufacture of penstocks and flashboards.
Filtramas manufactures channel hatches, wall hatches and cofferdams for different applications and uses.
The accumulation of solid waste in water treatment requires effective mechanized solutions for its extraction. FILTRAMAS, S.A. has a wide variety of equipment for the dragging of solid waste.
In the biological treatment of wastewater, a series of processes are generated based on the cultivation of bacterial microorganisms for the elimination of organic matter, nitrogen and phosphorus. It is one of the most common treatments for its simplicity and low cost.
FILTRAMAS, S.A. has a wide variety of equipment for bacterial culture applied to the treatment of urban and industrial wastewater.
The dewatering of sludge is an essential process in the management of solid waste generated in water treatment. FILTRAMAS, S.A. offers different mechanized solutions to the problem according to the different possible needs.
FILTRAMAS S.A. has a wide variety of solutions for all kinds of problems associated with the treatment and cleaning of water, mud and sand.
