Description

Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a water jet sand filtering device for a water jet cutting machine. Background Art

[0002] A water jet cutting machine is a device that uses high-pressure water to cut workpieces. Some types of water jet cutting machines add water jet sand to the water jet to assist in cutting, which can increase the cutting force and make the cut smoother. Some water jet sand is damaged and becomes smaller due to the impact generated during the cutting process. The water jet sand can be filtered through a filter device to reuse the intact water jet sand; the current announcement number is CN 219424845 A water jet sand filtering device is used in a water jet cutting machine of U. The water flow carrying the water jet sand falls into the funnel and falls onto the screening net from the lower port of the funnel. The damaged water jet sand and most of the water will pass through the screening net and fall onto the inclined plate, slide down to the right along the inclined plate and fall between the baffles, and be discharged from the sewage pipe through the guide block. The undamaged water jet sand is intercepted by the screening net and carries a small amount of water and slides down to the right along the screening net into the collection box. The undamaged water jet sand stagnates on the drain net and in the collection box. Then, when the water cutting work is carried out continuously and the collection box is full, the sealing plate can be driven by the hydraulic cylinder to close the lower port of the funnel, so that the funnel temporarily stores water, and the collection box is taken out. A new collection box can be replaced or the water jet sand in the collection box can be dumped and put back. Then the lower port of the funnel is opened again, and the water and water jet sand can fall again. However, the above-mentioned filtering device only relies on the gravity of water and water jet sand to vibrate and roll down from the screening net, and its screening effect is poor. In addition, when the filtered water jet sand needs to be transported, the funnel needs to be blocked, which causes inconvenience in use. Utility Model Content
