The principle of the water jet loom in this device is an existing known technology, and there are mature products and equipment, so no further explanation is made on its principle and related structure. The loom water pipe 1 of this device is connected to the water supply system of the water jet loom;

[0024] In one embodiment, a filter shell 3 is integrally formed on the surface of the loom water pipe 1, and a maintenance plate 4 is fixedly installed at the opening on the top of the filter shell 3 by screws, a debris collection cover 12 is welded on the maintenance plate 4, and the debris collection cover 12 is a hollow U-shaped structure as a whole, and through holes 14 and filter nets 13 are respectively provided on both sides of the debris collection cover 12. When the loom water pipe 1 supplies water to the nozzle 2, impurities in the water pass through the through holes 14 into the debris collection cover 12, and the filter net 13 of the debris collection cover 12 filters the impurities in the water, so that the impurities are retained in the debris collection cover 12, and with the continuous supply of water, the impurities in the debris collection cover 12 move with the flow of water, thereby maintaining the filtering effect of the filter net 13 and avoiding the situation where the nozzle 2 is blocked by impurities and the water spraying effect is affected.

When it is needed When replacing the nozzle 2, use the lifting hook 9 to pull the positioning ring 7 out of the arc groove 16, and then separate the T-shaped column 6 from the U-shaped ear 5. At the same time, when the loom water pipe 1 supplies water to the nozzle 2, the impurities in the water pass through the through hole 14 and enter the collecting cover 12, and the filter net 13 of the collecting cover 12 filters the impurities in the water, so that the impurities are retained in the collecting cover 12, and with the continuous supply of water, the impurities in the collecting cover 12 move with the flow of water, maintaining the filtering effect of the filter net 13, avoiding the situation where the nozzle 2 is blocked by impurities and affecting the water spraying effect, thereby indirectly improving the weaving efficiency.
