Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1 to 3, the present embodiment provides an adjustable air knife 100, which includes a hollow main body 10 and two blades 20 fixed on the main body 10, wherein the main body 10 has two vertical walls 11 that are parallel to each other, the ends of the vertical walls 11 each extend inward to form an inclined wall 12, and an opening 13 is formed between the two inclined walls 12; the blade 20 is fixed on the outer side of each inclined wall 12, the blade 20 is fixed on the inclined wall 12 in an attaching manner, an adjusting screw 30 is arranged between one end of the blade and the inclined wall 12, the other end of the blade is a free end and is suspended in the opening 13, the free ends of the two blades 20 are aligned and cover the opening 13 together, a certain gap is reserved, and the adjusting screw 30 is used for adjusting the size of the gap, namely, the size of an air outlet 21 formed between the free ends of the two blades 20 is adjusted.

Furthermore, a diverter plate 40 is included, said diverter plate 40 being arranged transversely between said two inclined walls 12. Specifically, the flow dividing plate 40 includes a first flow dividing plate 41 and a second flow dividing plate 42, the first flow dividing plate 41 is disposed near the opening 13, and the second flow dividing plate 42 is disposed near the vertical wall 11. The main body 10 adopts a structural design that the upper part is narrow and the lower part is wide, so that compressed gas can enter from a vertical wall 11 below the main body 10 and is ejected at a high speed from an air outlet 21 formed between the free ends of the two blades 20 after passing through the inclined walls 12 and the openings 13 which are gradually contracted. Due to the splitting and mixing action of the first splitter plate 41 and the second splitter plate 42, the wind speed and the wind temperature of the wind outlet 21 can be more uniform.

Specifically, one of the vertical walls 11 is provided with an air inlet hole 111, and an air inlet pipe 50 is connected to the air inlet hole 111. Or, two ends of the main body 10 are respectively provided with a baffle 60, one of the baffles 60 is provided with an air inlet hole 111, and the air inlet hole 111 is connected with an air inlet pipe 50. Wherein, the baffle 60 is connected with the main body 10 in a sealing way to prevent air leakage.

Because the vertical wall 11 has a relatively large plane, it is suitable for installing a larger air inlet pipe 50, and a higher power air drying process can be realized. The air drying efficiency is improved.

In this embodiment, the middle of the blade 20 is fixed to the outer side of the inclined wall 12 by a fastening screw 70, so that the blade 20 can be conveniently assembled and disassembled.

The two vertical walls 11 are connected through a bottom wall 14, the inclined wall 12, the vertical wall 11 and the bottom wall 14 are of an integrally formed structure, and preferably, the inclined wall 12, the vertical wall 11 and the bottom wall 14 are made of aluminum alloy.
