Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1-2, a termite-proof device by a deep dipping method comprises a dipping tank 1, a circulating pump 2, two throttle valves 3, a liquid conveying pipe 4, a plurality of guide needles 5, a plurality of capillary tubes 6, a collecting valve 7 and a plurality of transducers 8. Wherein, the dipping tank 1 is a hollow container, one side of the dipping tank is provided with the circulating pump 2, the upper opening 1a of the upper cover of the dipping tank 1 is provided with the throttle valve 3, and the throttle valve 3 is connected with the positive pressure end 2a of the circulating pump 2 through the infusion tube 4; meanwhile, impregnating solution 1b with a boric acid solution as a component is filled in the impregnating tank 1 and the circulating pump 2, and the wood member to be impregnated is immersed in the impregnating solution 1b in the impregnating tank 1; the flow guide needles 5 are hollow needle-shaped bodies, the tips of the flow guide needles 5 penetrate into the surface of the wood component at a certain depth and are distributed on the side surface of the wood component in an array form, the outer port of each flow guide needle 5 is connected with one capillary 6, the inner diameter of each capillary 6 is smaller than that of the infusion tube 4, the capillary 6 penetrates out of the impregnation tank 1 and is connected with the same collecting valve 7, and the main port of the collecting valve 7 is connected to the negative pressure port 2b of the circulating pump 2 through another throttle valve 3; the plurality of transducers 8 are installed at the bottom of the dipping tank 1 with their ultrasonic wave output directions upward.

The working principle of the utility model is as follows:

the wood member to be impregnated is loaded into the impregnation tank 1 in the above-mentioned manner, so that the plurality of guide needles 5 are uniformly inserted into each lateral side surface (see fig. 2), and then, the circulating infusion function of the circulating pump 2 is started, and the flow rate of the throttle valve 3 (see fig. 1) above the impregnation tank 1 is adjusted to be larger than that of the throttle valve 3 on the negative pressure port 2 b. At the moment, a large amount of impregnating solution 1b in the circulating pump 2 is poured into the impregnating tank 1 along the positive pressure end 2a and the infusion tube 4, and only a small amount of impregnating solution 1b flows back to the negative pressure port 2b along with the guide needle 5, so that a positive pressure state is formed in the impregnating tank 1; meanwhile, because the tip of the guide needle 5 penetrates into the wood member to a certain depth, if the impregnation liquid 1b needs to flow back to the negative pressure port 2b under the action of pressure difference, the impregnation liquid must firstly permeate into micropores on the surface of the wood member, so that the impregnation liquid 1b continuously permeates into the deep layer of the wood member from the periphery of the wood member under the action of suction force and pressure force, and then respectively flows back to the negative pressure port 2b of the circulating pump 2 through the tip of the guide needle 5, the capillary 6, the collecting valve 7 and the throttle valve 3.
