Timber internal micro blasting device

Abstract

The invention relates to a wood interior micro-blasting device, which comprises a pressure relief port equipped high pressure cylinder (A) for accommodating wood and a piston cylinder (C). The device is characterized in that: the high pressure cylinder (A) and the piston cylinder (C) are connected by a pressure relief cylinder (B), the pressure relief cylinder (B) wall near the pressure relief port is provided with an exhaust hole (4), the pressure relief cylinder (B) is internally provided with a cover plate (3) able to seal and open the pressure relief port; and the piston rod of the piston cylinder (C) stretches into the pressure relief cylinder (B) and is in fixed connection with the cover plate (3). As the high pressure cylinder and the piston cylinder are connected by the pressure relief cylinder for pressure relief, and the pressure relief cylinder is internally provided with the cover plate able to seal and open the pressure relief port, during pressure relief, the cover plate moves and is applied with a pushing force by the piston rod of the piston cylinder, the pressure relief speed is fast, the piston movement is stable, and the blasting effect is good.

Description

technical field [0001] The invention relates to a wood internal micro blasting device, in particular to a wood internal micro blasting device which is placed in a high-pressure cylinder for blasting. Background technique [0002] Wood is composed of tissues and cells with different sizes, shapes and structures, and the communication between them depends on pit pairs. Therefore, the permeability of tissues, cells and pit pairs is the key factor affecting the permeability of wood and wood modification. more crucial factors. Generally, this kind of wood internal micro blasting device involves the instantaneous release of high-pressure gas and part of high-pressure water inside the wood under the condition of maintaining the physical and mechanical properties and appearance of the wood itself. The tissues, cells and pit pairs inside the wood destroy the structure of the pit plugs, thereby fully improving the permeability of the wood. [0003] The Chinese utility model patent s...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned device has good operability, low cost, and good blasting effect. When the pressure is released, the piston moves to the right is driven by the high-pressure gas in the high-pressure cylinder. The pressure guarantees the blasting effect. Because the piston is relatively large and heavy, the moving speed of the piston is relatively slow, and the impact force acts on different points. Sometimes it is difficult for the piston to ensure a smooth movement, which affects the blasting effect.
