Plant for applying cleaning agents or paints

Field of application of the invention

The invention relates to a system for applying cleaning agents or paints on large areas, especially wagons.

Characteristic of the known technical solutions

Ea is known to aerate and vent the entire Spritsraum at Farbgebungsanlagen · For this purpose, especially in large systems, s.B. for wagons, complex equipment, needed «These require large plant areas, high energy requirements, high investment and maintenance costs *

Furthermore, in the case of large amounts of exhaust air, the separation of the pollutants is associated with very high additional costs and energy costs, which result from the use of catalytic afterburning plants and high exhaust chimneys.

In DE-OS 26 47 070 a device for surface treatment large units is shown, which is designed as a car with an open to the surface to be treated Mn housing. This cart contains applicators and removes horizontal straight or curved surfaces with seals against the surface. "Dieae device can only be used on horizontal surfaces and outdoors as there is no ventilation

Object of the invention

The aim of the invention is a system for applying detergents or paints with a small footprint, which requires low energy, investment and Y / art costs, but creates optimal working conditions and the needs of occupational hygiene and environmental protection to the extent necessary.

presentation; the essence of the invention

The invention has for its object to provide a system for applying cleaning agents or paints on large areas, especially wagons, with ventilation systems and with one or more spray portals, in which by the separation of the process zone of the occupied zone of the entire man Air requirement is considerably restricted ·

According to the invention the object is achieved in that guide rails are arranged on a portal base frame in which a cabin base frame runs. This carries a vertically movable and tiltable cab in which a worker or an automatic sprayer can be arranged. At the upper end of the cabin, a distribution channel for the supply air to the process zone is arranged, which is fed by a fan and at the same time forms the upper boundary of the process space. The cabin is supplied with fresh air by an additional fan via an activated charcoal filter · The lower boundary of the process zone forms baffles and a suction channel, which is followed by an actual extraction system and a flexible recovery pipe via a flexible pipe »

Laterally, the process zone is completed by boundaries, which are attached to the distribution channel or »on the suction channel *

The horizontally movable portal base is moved by means of an electric or pneumatic actuator and is guided on the ceiling or floor.

Inside the portal is the vertically movable cabin or a platform for automatic spraying, which is driven electromagnetically or pneumatically.

For rooftop spraying, the cabin can be tilted according to the required roof inclination or spray position. "When the cabin is scanned, the sprayer supports its body with installed upholstery straps, so that in extreme cases it can splash while lying down.

In manual spraying, the spray gun is located in front of the cabin. The splash in the cabin can guide the spray gun horizontally and vertically through a covered vertical slot in the cabin wall.

In order to ensure a perfect view during spraying, there is a vertically guided, transparent foil in front of the glass pane, which can be transported by a mechanical drive when a particular verse grade song is reached.

The control of the movement sequences of the cabin or dea gated spray portal as well as the manual spraying and the V / eitertransport the cabin screen film takes place from the cabin.

The Aualeuchtimg the process zone is done by luminous bodies that are installed in the cabin.

The cabin ventilation is carried out by the own supply air system. * The necessary air is sucked out of the room and treated by activated carbon filter.

In order to remove the paint mist arising during spraying as quickly as possible from the process zone, the supply air system sucks in air from the room and presses it vertically through the distribution channel into the Proseßzone between spray booth and side wall «

Since the distributor * and the exhaust air duct are connected to the cabin

  ; -; , '. ; - 4 - α ι a = w <α β

Rounds, they carry along all the vertical movements of the cabin and thus guarantee a uniform airflow in the process zone.

Only when tilting the cabin for roof spraying the exhaust duct remains in a horizontal position.

The fan for technological ventilation is mounted on a pedestal within the portal, which is connected to the cabin, and thus carries along all the vertical movements of the spray booth, while the exhaust fan only moves through the movement of the exhaust air duct «The solvent-containing exhaust air detected by the suction system through the flexible pipe in a channel located on the wall or in the floor and from there in turn to the solvent recovery plant, an activated carbon filter or in a catalytic incinerator can be printed.

When using activated carbon filter systems, a return of the purified exhaust air into the spray chamber and a return of the recovered solvent can be carried out.

The spray gun is supplied with paint via flexible hoses from a container. This container stands outside the cabin on a pedestal of the horizontally movable portal base frame.

The introduction of electrical energy and compressed air in the portal or, in the cabin is made by appropriate flexible cables and hoses.

For spraying the underframe, two opposing portals are moved horizontally as needed. Corresponding baffles on the suction channel are to be brought into the intended position.

The resulting paint mist is removed from the technological exhaust air systems of the injection portals and processed analogously to the side wall spraying ·

For the purpose of front wall spraying, the portal base must be moved to a certain position. There is a lock, and it is a pivot point

by means of hydraulic cylinders, supported by a roller on a guideway, swiveled by 90 °,

After the portal has been turned, the front wall can be sprayed in the same way as the sidewall spraying «

When using automatic spray systems can be dispensed with the cabin, in principle, the technology of spraying and the ventilation system and the exhaust air treatment can be maintained ·

The interior spraying is made possible by two opposing Parbspritzanlagen · For better air conduction flexible pipes are used ·
