SU914103A1 - Apparatus for applying coatings on reservoir inner surfaces - Google Patents

Description

The invention relates to mechanical engineering, in particular to equipment for coating, and can be used when painting the internal surfaces of containers, for example, containers.

A device for paint the inner surfaces of containers, containing a hydraulic filter connected to a system of ventilation suction, and. air distributor giving. fresh air in the upper part of the container to create normal conditions in the painter’s breathing zone (1).

The drawbacks of the device are the inability to produce air exchange in the whole volume of lengthy containers and the fact that during painting the costume and footwear of the painter are polluted, because the polluted air is sucked through the floor grille, which is also a workplace.

Closest to the proposed technical essence and achievable2

The result is a device for coating the inner surfaces of the containers, containing a console to accommodate the coating device, a vein® suction filter system and drive supports for moving the container being processed [2].

A disadvantage of the device is that when the ⁰ is not excluded the possibility of contaminated air entering the atmosphere.

The purpose of the invention is the improvement of sanitary and hygienic working conditions in the processing of long containers.

This goal is achieved by the fact that the device for coating the inner surfaces of tanks, containing a console for accommodating a device for coating, a ventilation suction system and drive supports for moving the container being processed, are mounted mounted on the free end

console screen with two pairs of shutters installed with the ability to move in two mutually perpendicular directions with the formation of the opening dt? air leaks and placement of hydro-filters for air-conditioning, covering, and hydro-filters connected to the ventilation suction system with openings for suction of polluted air made in the screen, the console being made of telescopically connected sections.

FIG. 1 shows the proposed device, a general view; in fig. 2 the same, top view; in fig. 3 “section 15A-A in FIG. one.

The coating application device comprises a console 1 on which the coating application device 2 is placed, the drive supports 3 for moving the treated container. At the free end of the console, a screen 4 is mounted with two pairs of shutters 5 installed with the possibility of moving in two mutually perpendicular 25 directions along the x and y axes with the formation of aperture 6 for air leaks and placement of the coating application device 2, and hydraulic filters 7 with openings 8 for suction of contaminated air 30, made in the screen 4. Hydraulic filters 7 are connected to the system of ventilation suction 9 · The console is made of telescopically connected sections. 35

The device works as follows.

The treated container 10, for example a container, is driven into the coating area with the aid of power bearings 3. The drive mechanism of the telescopically connected sections of the console 1 is turned on and the console is inserted with its free end into the container 10 to be processed. After turning on the hydraulic filters 7 ₄₅

by moving the shutters 5, they form an opening 6 of a given size at a given place and begin to apply the coating material (paint) by means of the device 2. Next, turn on the drive (not shown)

s * ·

move the free end of the console to return to its original position and continue painting with continuous movement of the free end of the console or by stopping the free end of the console 1 at specified intervals. From the air-painting zone, contaminated with paint aerosol and solvent vapors, through openings 8 is sucked into hydraulic filters' 7 for cleaning.

The use of the proposed device can significantly improve the sanitary and hygienic working conditions when applying a coating on the inner surfaces of containers.

Claims (1)
