We recommend using the system for electricity supply to homes, vacation homes, farms or isolated locations that do not have access to electrical distribution network, or the connection to the electricity is very expensive.

The power range available is 1 to 10 kWp.

A 1.5 kWp photovoltaic installation ensures an average daily energy production of 5 kWh.

Working principle

The role of the instalation is dyeing and drying the pieces painted with liquid paint.

Transportation of parts is made by a conveyor.

The system can operate both in manual mode and automatic mode.

The operating temperatures of the painting and drying system are adjustable.

In manual mode of operation, all elements of the system can be operated independently, for maintenance or test purposes.

Commands are available on the two screens of the display, Microwave Drying and  Painting Booth.

The two instalations, Spray Booth and Drying Oven, can operate simultaneously but independently of each other.

Modes of operation

In manual mode , each unit of the instalation is operated as long as you hold the button. When the button is released, the machine stops operating.

The status of the entire system is indicated via lights.

In automatic mode the system operates completely independent of operator intervention, considering only the parameters set in advance (running time, rest time, temperature, etc.) and if safe operating conditions are met.

Functional safety

All faults that occur are signaled both optically and acoustically.

The windows are made with graphics, databases and lists of failures.

 Comfort and ease of use

The system is equipped with a generously sized touch screens that can easily view all elements in the system.

The system has the possibility to connect to ethernet, which allows viewing and remote monitoring of the entire process.

It also has the possibility of a memory stick to certain parameters in the system.

Operating principle:

The system is designed to purify and bring industrial wastewater, from various stages of production at an appropriate pH content requirement and environmental standards in force, before it is release into drains. The system performs in the filtering process the pressing of the resulting sludge and the recovery of valuable components such as copper, zinc, aluminum, chromium, etc.

The principle consists in successive dosages of hydrochloric acid, lime, caustic soda, flocculants and other chemical components, after a well-established recipe with the possibility of amending it so that all the compounds in wastewater are neutralized. Sediments are effectively eliminated, water becomes clean, providing output pH and content of harmful compounds to the parameters required by environmental regulations.

The system supplies a complex traffic monitoring and constrol installation.

In “Documentation” there are technical descrieiri System 25 kW, 3 kW and 1.5 kW.

Operation is how automation conveyors, elevators, ventilation and dust absorption function’s thus the phenomenon of blocking the installation does not occur. In this way, each conveyor or elevator, starts or stops with a certain delay to achieve gradual loading or unloading.

If blockage or rupture of a vonveyor or elevator, the overflow transducers, or the protection of the drive motor, will stop that conveyor along with all conveyors and elevators transporting material to the damaged conveyor, leaving in operation a predetermined time conveyors and  elevators transporting material from the damaged equipment.

Modes of operation:

The system has three modes: unload, recirculation and transfer silo products. Each of the three phases can operate independently and simultaneously.

The system can work both in automaticmode, where all decisions are taken by the automatic control of the installation, depending on the chosen silo phase and in manual mode, where the system can make checks and adjustments on silo process for each conveyor or elevator. The system is also provided with a semi-automatic system, which involves a combination of manual climate control system, meaning that the chosen stage, discharge, recirculation or transfer system operates automatically, coupling with by a certain timing the conveyots or elevators, but only the ones and tup to those which have been manually selected, of course in order of chosen phase succession.

The ventilation and dust absorption equipment is implemented so that it starts before the  elevators and conveyors and stop after them, thereby ensuring efficient dust removal.

Functional safety:

The system performs a good signaling and warning situations process, by gathering faults present in the fault list, showing the date and time when the fault apperared and disappeared and assuring audible signals when they occur.

The list of faults is stored in a “.csv”  on the PC and can be accessed and printed, making process history for long periods of time.

Comfort and ease of use:

Each stage of the process and pH values are shown in real time and stored in process lists that can be accessed both on the PC viewer, and in a “.csv” file, logging the history of the instalation’s parameters in time.

Automation is ensured by a Siemens ”Step 7″ series programmable controller and S300 digital and analog modules, which monitor and control the entire process of neutralization.

With the graphic touch screen and SCADA program under  “Siemens Flexible 2008 Runtime” licence,  viewing, control and HMI interaction with the installation is made posible.

Fiabiliate:

Automation cabinets are made with Schneider Electric devices , providing a high robustness and a very good reliability.

A 3 kWp system capacity will produce an average of 300 kWh / month, enough to cover the energy needs of a house at a rate of almost 100%. Together with a bidirectional meter, the energy produced but not consumed during the day will be injected into the grid and capitalized. In a way, not only will it eliminate electricity bill, but it will make money by selling energy.
