The gateway consists of the following separate elements:

- Hollow side rails.
- Center Supports drag anchor swivel blade.
- Support kingpin opposite end.
- Central grid step hot-dipped galvanized frames.
- Anchoring gear motor end.
- Stairway access decanter (optional)

Kingpin

Built to monoblock system, only one anchor must work, so it is envisaged the introduction of four studs.

It incorporates a collector brushes motorredcutor feeding drive peripheral.

The connection is made via sealed boxes placed on that pivot.

The roller bearings are protected RS, and should be greased once a year.

Background Scrapers

Within the manufacturing program, we can mention two types:

- Discontinuous (fishbone)
- Continuous (bottom band)

Both of them are system Nylon wheels with stainless steel shaft from sliding through the bottom of the tank.

Sludge Scrapers sweepers are Neoprene, and adjustable for fit, so it compensates for wear of the rubber.

Finish according to plans.

Any circular bridges can be equipped for placement as a primary clarifier.

The floating collector consists of three elements:

Drag 1.Chapa water level.
2.Arqueta floating collection.
3.Paleta filling.

Drive plate

Hanging from the bridge walkway, is height adjustable.

Casket collection

Made of sheet steel, is supplied ready for attachment on site and outlet pipe to the outside of the floats. Standard pipe diameter 200 mm.

Fill Palette

Placed at the end of the bridge walkway, is responsible for raising the float to the chest.

Just drag the floating water largely serves as a vehicle of these, so we avoid bottlenecks outside the outlet tube.

This rating is based primarily on the location of the appropriate gate on the burden of water received, however not limited ESTRUAGUA, as it is in a position to consider, resolve and build any type of gate in accordance with customer needs ,

As drive systems of the gates, you can use the following procedures,

1 .- Manual.
2 .- electric gearmotor.
3 .- Power servo.
4 .- Water.

Manual operation .- Such action is conducted by means of a brass nut in conjunction with trapezoidal thread spindle, and a handwheel whose technical characteristics are described in the design of the gates also include bearings, ball bearings and bronze bushings or nylon. This drive on the gates of a single screw can be direct or via the reduction gear, thrust bearings or roller ball.

Drive by motor reducer .- The gearmotor to be introduced is applied depending on the size and hydraulic pressure in the gate. Optimal speed that will produce minimal wear of the screw in the rise of the gate (0.03 m / min.). The electric drive is accompanied by an electric torque limiter to avoid overexertion, and two limit switches in terms of bottoming.

In a screw locks the gear motor is directly coupled in gates of two screws were placed at the end or the center of the gate and always with two forwards. Take a manual emergency steering.

Driven by servomotor .- Be housed in the actuator stroke end, clutch, and regulatory mechanisms of the gate, which will regulate the levels. The wrath of the servomotor position depending on the number of spindles as the gearmotor.

Hydraulic .- Using hydraulic cylinders, only has application in a single screw gates. The stem is attached directly to the gate and the cylinder is anchored to the bridge of the gate. The system will be opening on-off.

Calculation of hydraulic pressure to channel gates:

L = Light free-span in meters. (W Channel)
H = Maximum water meters. (Lamina water channel)
Ph = hydraulic pressure on the board in kg

For gate channel with reinforced board and sheet rolls of displacement,

Ph = 500 x (L + 0.08) x H2

For all other choppers channel gates,

Ph = 500 x L x H2

Calculation of hydraulic pressure to channel gates:

L = Light free-span in meters. (W hole)
H = Maximum water meters. (Lamina water channel)
Ph = hydraulic pressure on the board in kg
H ‘= maximum load of water on the center of the gate. (Difference in gate sheet water)

H = Height in feet of the span.

To scroll roller gates,
Ph = 1000 H’x (L +0.1) x (h +0.05)

For small gates bottom outlets,
H’x Ph = 1000 (L 0025) x (h 0025)

For flat slide sliding
Ph = 1000 H’x (L +0.05) x (h +0.03)

Description gates:

Guide frame .- Built in stainless steel AISI 304 or 316, the board serves as a guide introducing concrete in civil works faster in the slots left for that purpose in the channel. The height of the frame is advisable to exceed 900mm in height from the floor of the maneuver.

Motherboard .- Built in stainless steel AISI 304 or 316, welded to the top of the frame. The brackets are placed drive. Shall consist of a rolled frame Upn where to attach cross-references where appropriate and necessary to drive the transmission from the side in the course of two spindles.

Gate board .- Made of sheet steel AISI 304 or 316 of thicknesses between 5.00 and 8.00 mm, with the necessary reinforcements to the soldiers rolled sheet and calculated to withstand the maximum hydraulic pressure. In the top center of the housing for carrying soldiers nut that gives movement to the board. In the center and take its entire length welded protection tube of the screw.

Travel Guides .- Low density polyethylene, a product with a very good self-lubricating sliding conditions. Are located at the ends of the board and supportive of this move through the frame that acts as a guide making transverse and longitudinal slip.

Seals .- The closure is made by stainless steel plates AISI 304 or 316 complementing the profile of neoprene Gr. 50-60 Shore A hole in the sides and bottom.

Clamping wedges .- Adjustable for a perfect fit, made of bronze, bolted to the board and the frame.

Drive Mechanism .- Comprising screw, steering wheel, column switching and forwarding. The spindle is made of trapezoidal screw DIN 109, stainless steel AISI 303, diameter depending on the length so as to limit the arrow to 1 / 1000 of the length.

Bring on the top for attaching a machined area of ​​the wheel support. The twin-screw assembly is made from gate width above 1200mm.

The nut is made of bronze material for driving the spindle. These will be housed in the top of the board or the bridge (column) depending on the procedure that is screw up or fixed.

The wheel is constructed of cast iron, will be housed in a bearing support with improving maneuverability.

Forwards .-They are airtight boxes which house a set of gears bevel pinion and crown, bearing trees, etc. Agree that vertical movement horizontally. Gates are mounted on twin-screw, depending on the effort needed to maneuver. The crown gear ratio will be 1:2 to reduce the torque required at the end of maneuver.

It consists of an alternative scanning mechanism mounted on a rectangular tank, on top of the side walls of the tank is installed wheel paths (Red Band), which moves on a metal bridge, under which and solidarity with the same arms are to sweep the surface and bottom (sludge floating sweeper).

The carriage movement is made through an electric geared motor transmits motion to a shaft that connects the two drive wheels placed one in each car, the transmission of movement is done by wheel axle + + engine, printing a final speed the car below .= 3mts/min 5cm/seg.

Duty Cycle

1.Manual (Only one course).
2.Manual (Continuous)
3.Temporizado.

The car moves in the opposite direction of the current, on reaching the opposite end, a limit switch installed on the end acts on the drive by reversing its operation and therefore the direction of travel of the car, at the same time , a mechanical stop arms free allowing it to fall cleaning, after completing these operations, the car begins its march this time in reverse.

Having made its way down it, the blade pushes the floating scan within the landfill, while a mechanical system that raises his arms held in this position, other electromechanical limit switch located at this end, disconnect the drive holding the system .

The system will be protected against overvoltage.

The bridge sweeper consists of the following elements:

Bridge built in rolled carbon steel (A/42-b) constructively main machine at both ends are located the so-called factors cars, built in rolled carbon steel (A/42-b). These cars are mounted wheels translation of the whole.

Footbridge over the bridge, allowing access to any part of it, network construction will be galvanized.

Placed around the bridge railing for protection, built in hollow carbon steel (A/42-b) in the corresponding end of the bridge open anger, supplemented with one or more steps in terms of height at which the gateway is soil.

Built in wiper arm and hollow carbon steel plate (A/42-b) or stainless steel AISI-304 or 316, with their reinforcements, bumpers and other components for proper operation.
