Overview:One of the biggest problems in treating wastewater, pretreatment is physical, conducted at the beginning of the plant. Its smooth operation depends largely on the performance of the treatment plant.

In the pretreatment, the most contentious point is the separation of water from the coarse and fine solids and disposal.

This separation is usually done by manual or automatic gates.

Our company through the construction license has been working for 19 years in the manufacture of equipment for wastewater treatment, especially in the construction of both manual and automatic gates.

Our production will center on:

Rejas DA-001 Automatic Hydraulic
Rejas DT-011 Automatic Straight
Rejas automatic DB-011 Cable
Automatic Circular Grating DC-011
DM-011 Grills Manuals

And in addition;

Waste conveyor auger. SFH-215
CH-012 Hydraulic Compactor

In the 70′s, beginning of our activity, automatic gates were manufactured in our workshops were basically mechanical drive, chains, sprockets, etc …

Over the years we have worked towards a gate that had the least maintenance possible, so we’ve tried to eliminate the elements that always cause problems either rust, breakage, such as

Submerged Sprockets
Bearings
Chains, to break or rust
Rake combs fixed guides
Mechanical torque limiters
Gearboxes, chains and sprockets union
Roller wheels and guide combs.

We have also tried to avoid;

The comb has a fixed route and guides to slide, stop to avoid breakage and hooks.

Move the comb to the bottom of the channel by its own weight, because if there is any large object comb chains stops and headphones in a twist.

The comb has its way upstream in a fixed guide, and that finding large objects that you can not drag, or stops or breaks, because you can not change its course.

- No pinion
- No strings
- No bearings
- No mechanical torque limiters.
- No gear
- No roller wheels
- No fixed guidelines for the comb

In the year 1983 mounted the first two bars that met these requirements at the WWTP Vilanova i la Geltrú for our client Dragados Construcciones, SA

From that date we have continued to build while our technical department has been making improvements that have increased performance and reliability and reduced maintenance.

Basically the idea of ​​running the Grate DA-011 ® is reproduced by means of a head and two oil hydraulic cylinder, the movements that a person would make a grate clean with a rake, which would,

- Raise the portcullis, and lowered to the bottom of the channel
- Nail rake in the gate and pull the mime, raising the solids retained on the grid
- Download the solids retained in a container, endless conveyor belt, basket …

For the operation of the Bars DA-011 ®, There is a control panel placed on a desk, which contains the hydraulic and electric, are located in the panel;

- A function selector, automatic, manual, unemployment.
- A Start button and a stop.
- A schedule timer.
- A pilot control gear.
- A pilot thermal fire control.
- A switch.
- A pilot network indicator.

If the fence is equipped with a host of origin, compactor or garbage removal tape, the panel will include,

- A function selector, automatic, manual, unemployment.
- A pilot control gear.
- A pilot thermal fire control.

In this panel, protected by a clear acrylic shell that prevents it from getting wet in case of placement through it.

When the grill is placed in areas not fenced or guarded, the control panel is protected by a locked metal cover fitted, which prevents it from being manipulated by outsiders.

One of the advantage that the operation of the Da-011 Grille, is that any movement the rake, has fixed Degui, which means that if you can not raise the amount of solids retained or whether an object is retained through, stops rising, rises above the object, move forward and back down continuing its way to the point of discharge.

To eliminate maintenance problems have placed their elements;

- Arm scraper, Quality Stainless Steel AISI-304 or 316.
- Supports external Nylon (no grease).
- Filter Grid, Stainless Steel AISI-304 or 316.
- Body and frame in carbon steel or hot dipped galvanized.
- Hydraulics, submerged in oil.
- There is no mechanical element submerged.

All maintenance is reduced to monitoring the oil level in the tank.

Due to the particular operating characteristics of the Fence DA-011 ®, Have developed a grid of triangular profile which achieves an effective step up to 1.00 mm, and rake this grid that acts on this, are stainless steel, and is free of spikes.

Operation:

Manual position:

The dial to manual mode, then press the run button, bringing down the rake to the bottom of the channel, at the end of the trail approaches the screen and dragging the objects that amount being held, to his position. A scraper, clean the rake to reach the top position.

At any point on the course, pressing the stop button, the rake stops, maintaining its position to initiate movement, pressed again and button fly.

Automatic Position:

The dial to Auto position, the operation of the grille shall be determined by the timer, which can determine how many times an hour want to operate the grid and for how long.

The cycles described in the manual operation is repeated in the automatic.

If the fence is equipped with a roller, auger, or conveyor belt, switch the position of the same machine, this will work in unison with the grate. For the purpose of the teams mentioned are not full of garbage, when the fence made the last sweep and stop the compactor, conveyor, or tape, continue running for a few seconds, enough for complete drainage.

Safety Equipment:

The movement of the rake, downhill, uphill, and the approach to the grid, is protected with force limiters, which act directly on the flow of oil, which feeds the hydraulic cylinders.

These limits are easily adjustable and being inside the desk and oil bath features are not affected by the passage of time.

The firing of any of them produces the stop of movement control, without allowing it to damage the fence or any of its components.

There are four limiters, which protect different pressures the four movements of the two cylinders.

This allows us to adjust the effort of each movement independently of the others.

Electrically magnetothermic Reja is protected by differential and switch.

For switching circuits, both internally and externally, the tension has been 24 v, regulatory compliance manual.

Optional equipment:

For the implementation of the grid, this can be equipped with;

A buoy maximum upstream in the post excessively high blood glucose indicating a contamination of the grid, the grid can be run until the level drops, this would occur as long as the selector of the grid is in automatic position .

The standard electrical circuit box of this buoy is scheduled to exit a power strip not the buoy.

A buoy upstream and downstream, we will float down running order when the level drops to a minimum, as long as the upstream buoy us to detect that there is a higher level.

A detection system pressure loss, this system allows us to predetermine a maximum pressure drop, depending on which will be launched in the Grate. The system to be used by two ultrasonic sensors or even by two detectors and a differential pressure measurement.

Remote control, the control panel, you can provide outputs to detect electrical faults remotely trigger thermal engines, we can also tailor a device that tells us a general failure to produce any item that can not finish a limpiarejillas cleaning cycle.

The grid DA-011 ®Is constructed as following,

- Fixed Frame
- Tailstock
- Control panel
- Filter Grid

Fixed Frame:

Made of sheet steel welded, forming the support of the whole, forming a fixed bed that attaches to a metal profile structure, which has the mission to secure the fence to the ground with metal studs or bolts.

Moving Head:

It is built of sheet steel welded and stabilized before mechanization, the head support arm with the razor scraper collection.

The wiper arm is made of stainless steel tube and slides through plastic bearings, wear and needs no lubrication.

The rake movement is effected by hydraulic cylinder.

The moving head, is fixed to the fixed frame by a shaft that allows a rocking motion, by which we get the rake up high and pressed down the grid. This movement was managed by another hydraulic cylinder, the cylinders are built with standard materials and parts that are in contact with water, have a hard chrome finish to prevent corrosion and wear.

The rake is built in carbon steel material welded tines are manufactured in a separate piece, making it easy to change when worn.

When the grid is triangular profile of stainless steel, razor blade is replaced by a line of aluminum or other suitable material.

All heads incorporate a waste ejector, which cleans the rake once available becomes higher.

Control panel:

It consists of a metal cabinet in the bottom of which is located in the hydraulic oil tank.

At the front of the desk and protected by a perspex panel, are the controls of the grate.

The hydraulic unit consists of two independent circuits of oil, produced by two gear pumps and commanded by solenoid valves, regulators and pressure relief.

All equipment is manufactured under EEC standards, so that its elements can be found easily in the market.

Attached to the desk or inside the electrical panel is that we automate the operation of the grate being protected by means of differential thermal and fuses.

Grille:
