Wood impregnation device

The invention relates to equipment for wood impregnation. A device is known that includes a hermetically closed impregnation chamber, a bath for impregnating liquid and a liquid pump,

interconnected by a system of pipelines and cranes (Balod V.V. Experience in wood preservation in the Latvian SSR, Riga, Knowledge, 1979, p. 76-79).

This device provides only a gradual decrease in atmospheric pressure to a deep vacuum and is not suitable for an abrupt change in pressure in the impregnation chamber.

A device for impregnating porous materials containing a hermetically sealed impregnating chamber, a container for impregnating liquid, a receiver and a liquid and vacuum pump, interconnected by a system of pipelines and valves, and it is equipped with a container connected to the suction pipe of the vacuum pump, connected, in turn, through vacuum shutter with a high-speed trigger with an impregnating chamber (patent No. 20111511, IPC V 2Z 3/02) - prototype.

The disadvantage of this device is not the optimal layout of the main components and, as a consequence, the complexity of the design.

The technical task of the inventive utility model is to reduce the energy intensity of the process of prosperity due to the rational location of the main nodes, reducing the cost of the device.

eleven

This object is achieved in that the known device comprising a hermetically sealed impregnation chamber, a container for impregnating liquid, a receiver, vacuum and liquid pumps interconnected by a system of pipelines and taps, the receiver is located above the impregnating chamber, and the container for impregnating liquid under it, this impregnation chamber is connected to the receiver by means of a vacuum shutter, and with the capacity for the solution through the tap start and discharge solution. The receiver and the impregnation chamber are inclined relative to their horizontal axes so that the impregnation liquid can drain from the receiver into the impregnation chamber and from it into the impregnation liquid tank

Comparison of the claimed utility model shows that it differs from the prototype in the following features:

- the receiver is located above the impregnation chamber;

- the container for the impregnating liquid is located under the impregnation chamber;

- the impregnation chamber is connected to the receiver by means of a vacuum shutter;

- the impregnation chamber is connected to the solution tank by means of a faucet for starting and discharging the solution;

- The receiver and the impregnation chamber are inclined relative to their horizontal axes.

1 and FIG. 2 schematically shows a device for impregnating wood.

The device comprises an impregnation chamber 1, a water ring vacuum pump 2 and a hydraulic pump 3, located above the impregnation chamber

receiver 4 connected to it by a vacuum shutter 6, under the impregnation chamber there is a reservoir for a solution 5 connected to it by a start and discharge valve 7. A plug valve for the hydraulic pump 8, a plug valve for the vacuum pump 9, a valve for connecting the impregnation chamber to the atmosphere 10 are located on the pipelines , a vacuum gauge 11, a pressure gauge 5 gauge 12, a water meter window 13, a non-return valve 14 of the vacuum pump and 15 of the padron pump.

The device operates as follows. In the receiver 4 using a liquid ring vacuum pump 2 creates a vacuum, while the vacuum shutter 6 is closed, the plug valve 9 is open. When a certain degree of vacuum is reached, pump 2 is turned off. Then, the impregnation chamber 1 is loaded with wood, while the crane 7.8.10 is closed. After loading the chamber, the vacuum shutter 6 opens. After equalizing the pressure in the impregnation chamber 1 and receiver 4, the pump 2 is turned on again and the vacuum is brought to the required values, then the pump 2 is turned off and the wood undergoes a vacuum process. After evacuation, the pump 2 is turned on again, the vacuum is brought back to the initial one and the valve 7 is opened, when an impregnating solution appears in the water metering window 13, the vacuum shutter 6 is closed and the pump 2 is turned off. The wood is impregnated with the open valve 7 until a constant vacuum is established on the pressure gauge 12. The crane 7 closes, the valve 8 opens and the hydraulic pump 3 is turned on to increase the hydraulic pressure in the chamber. The pump 3 is periodically turned off, while the pressure gauge is monitored 12. A significant slowdown in the drop in hydraulic pressure when the pump 3 is turned off is an indication of the end of the impregnation. After the impregnation, the pump 3 is turned off, the valve 8

close. The faucet 7 and then 10 are opened, the remaining solution is gravity drained into the container 5. The impregnated wood is removed from the chamber.
