Description

one

The invention relates to the woodworking industry and relates to a device for impregnating wood with solutions.

The known device for impregnating wood with solutions, including a container with pipelines, inside of which a chamber with a bottom and a lid is located, does not ensure uniform impregnation of wood.

In order to ensure uniform impregnation of finely chopped wood, for example, shavings or sawdust, in the proposed device, inside the container with pipelines, a chamber for the impregnated wood is mounted, made movable in a vertical plane, and the bottom of the chamber and the crest are perforated.

The drawing shows the proposed device.

The device consists of a tank 1 with a lid 2 and pipes 3, 4 and 5. Inside the tank is a chamber 6, to the perforated bottom 7 of which is attached a rod 8 attached to the actuator (not shown). On the outer surface 9 of the chamber 6 there are grooves with a seal 10. At the bottom 11 of the container 1 there is a groove with a seal} 12. Inside the chamber 6, a rod 13 is attached to the perforated bottom 7, along which the perforated cover 14 moves, pressed down by a nut 15 through the sleeve 16 .

Before starting the operation, the chamber 6 is moved to the upper part of the container 1, and with the covers 2 and 16 removed, the impregnated material is loaded. Then, the lid 16 is put on and the buried material is compacted with the nut 17 and the sleeve 18, the container 1 is closed with the lid 2 and the air is pumped out through the pipeline 3. Then through the pipeline 4 serves the impregnating solution to fill the free

the spaces of the container 1, and when the pipes are blocked, turn on the drive and move the chamber 6 down and up through the solution, which passes under pressure through the perforations in the bottom 7 and the cover 16 through the layer of material. After a specified time, the drive is turned off and the solution is removed through line 5, the lids are opened and the finished portion of the impregnated material is unloaded.
