(54) SETTING FOR WOOD PROTECTION WITH PROTECTIVE LIQUIDS

I

FIELD: woodworking. tillage and can be used for antiseptic lumber staining, for example for antiseptic flooring.

Devices are known for treating wood surfaces jia conveyor lines, which provide for the application of a protective liquid by a sprayer, brush, or immersion 1.

However, the level of protection of wood on such devices is relatively small and significantly depends on the rough surface of the wood surface.

The closest technical solution to the invention is a device for treating wood with protective liquids, comprising a chamber with inlet and outlet openings for passing the treated wood, a container and a device for applying protective liquids 2.

The disadvantage of these devices is the poor quality of processing.

I The purpose of the invention is to improve the quality of processing.

This goal is achieved by the fact that the camera is equipped with a rotating brush, the motor is installed between the outlet, the camera and the device for applying protective liquids.

Repeated contacting of the bristles of the brush with the treated wood, the surface of which is under the liquid, helps to remove air bubbles, prishlichin and pinched on the turned wood and the kinetic indentation of rubbing the liquid in the capillaries to the pores of the wood

15 sina. Of particular importance is the treatment of wood with EHE fluxed fluids.

The drawing schematically shows the installation, general view, section.

20

The installation contains a chamber 1 with an inlet 2 and an outlet 3 with holes for passing the treated wood (board) 4, a container 5 with liquid and

a device for applying protective liquids 6, the chamber 1 is equipped with a rotating brush 7, which is installed between the outlet 3 of the chamber 1 and the device for applying protective liquids. The rotating brush 7 is covered with a protective cap 8 to prevent liquid from splashing on the walls of chamber 1 and on the part of the board that has already been processed. A container 5 for draining and storing the liquid is attached to the bottom of the chamber 1 and provided with a filter screen 9.

The installation works as follows.

Before starting the supply of wood (board) 4, the pump of the device for applying protective fluids b and the drive of rotation of the brush 7 are turned on. The wood (board) 4 is continuously fed through the roller conveyors through the inlet 2 to chamber 1, the working zone passes between the nozzle of the device for applying protective fluids 6 and brushes 7, where it is subjected to pouring and impact of a rotating brush 7. Liquid from the reservoir 5 is pumped through the pipeline to the device for applying protective liquids 6 through a conduit to a nozzle, which pours wood (water ku). The excess fluid is removed with a brush 7 and the passage of the filter screen 9 is collected in the container 5. The liquid splashes from the rotating brush 7 are collected and removed by the protective cap 8 also into the container 5. After processing the wood through the outlet 3 on the roller table comes out of the chamber .

The proposed installation qualitatively conducts surface treatment of lumber with fluids in mass production, for example, for three-sided use of flooring boards, and is also used for deep painting, for example, for products such as cladding

the boards. At the same time, the installation provides a high degree of hygiene and labor safety, and allows fully automating the process of chemical processing of wood.
