Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile machinery, and particularly relates to a water circulation filtering device of an oxford fabric water-jet loom. BACKGROUND

[0002] The water-jet loom belongs to the jet loom, which uses water as weft medium, generates frictional traction force on the weft yarn through water flow, and introduces the weft yarn fixed on the bobbin into the shed. Since the water flow has good aggregation, the water-jet loom does not have any water flow diffusion device, and even so the reed width of the water-jet loom can reach more than two meters. The water-jet loom has good water flow bunching, and the frictional traction force of water on the weft yarn is also good, so that the weft yarn flight speed and the loom speed of the water-jet loom are the highest among all kinds of looms.

[0003] The water-jet loom needs a large amount of water to be sprayed through the nozzle in the process of use, and the used water flows into the water collecting tank, and then flows into the water tank of the water-jet loom from the water collecting tank. The water does not pass through the filter directly and flows into the nozzle, which is easy to cause blockage. Therefore, the water circulation filtering device is provided on the existing water-jet loom, but the filter screen will be blocked by the accumulated sundries after long-term use, which is easy to cause the decrease of the circulation water flow, resulting in the decrease of water pressure and affecting the normal operation of the loom.
