Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, specifically to an ultra-high pressure water filter element that is easy to clean. Background Technology

[0002] Waterjet cutting, also known as water jet cutting, is a machine that uses high-pressure water jets for cutting. High-pressure water jet technology uses the principle of liquid pressurization, which converts the mechanical energy of the power source into pressure energy through a specific device. The water with huge pressure energy is then converted into kinetic energy through a small nozzle, thus forming a high-speed jet for cutting. The water produced by cutting is collected in a water tank, and the wastewater is filtered by a filter screen in the water tank. The filtered water can be collected and reused.

[0003] When existing water collection tanks are in use, filter plates are generally required to filter wastewater to reduce cutting debris, iron filings, and other contaminants in the wastewater, making it easier to recycle. However, when filtering in a water collection tank, large particles such as cutting debris and iron filings tend to accumulate on the surface of the filter plates, causing water flow obstruction and requiring frequent shutdowns for cleaning. This can easily affect the recycling and reuse of wastewater.

[0004] Therefore, we propose an ultra-high pressure water filter element that is easy to clean to solve the above problems. Utility Model Content

Both the coarse filter chamber 2 and the fine filter chamber 3 have sedimentation tanks 5 at their bottoms. A flushing pipe 6 is connected to the front of the sedimentation tank 5, and a drain pipe 7 is connected to its rear. The coarse filter chamber 2 has a connecting pipe 8, and a stainless steel coarse filter element 9 is fitted onto the connecting pipe 8. The fine filter chamber 3 has a short pipe 10, and a stainless steel fine filter element 11 is fitted onto the short pipe 10. A top cover 12 is installed on the top of the housing 1, and a pressure sleeve 13 is provided on the top cover 12. A [missing information - likely a component or element] is installed in the pressure sleeve 13. The high-pressure backwash nozzle 14 intercepts large particles of cutting debris and iron filings through the stainless steel coarse filter element 9 in the coarse filter chamber 2, preventing direct clogging of subsequent filter elements. The stainless steel fine filter element 11 in the fine filter chamber 3 further traps fine impurities, achieving dual-effect filtration. The internal high-pressure backwash nozzle 14 directly impacts the surface of the filter element with periodic backwash water flow, quickly removing clogged debris and iron filings, preventing water flow obstruction due to long-term clogging of the filter element, and reducing the frequency of downtime for cleaning. The sedimentation tank 5 can collect large particles of impurities. With the linkage design of the flushing pipe 6 and the drain pipe 7, the sedimentation, flushing and draining of impurities are integrated, further reducing the workload of manual maintenance.

The lower part of the high-pressure backwash nozzle 14 is placed in the stainless steel coarse filter element 9 and the stainless steel fine filter element 11, respectively. The water to be treated first intercepts large particles of cutting debris, iron filings, etc. in the stainless steel coarse filter element 9 in the coarse filter chamber 2, and then is introduced into the fine filter chamber 3 through the connecting pipe 8. The stainless steel fine filter element 11 further intercepts fine impurities, achieving dual-effect filtration. Then, it is introduced into the water collection chamber 4 through the short pipe 10 for reuse. The high-pressure backwash nozzle 14 is precisely aligned with the filter element, and the backwash program can be started periodically or as needed.

[0029] like Figure 1 As shown, in some embodiments, the coarse filter chamber 2 is provided with a water inlet pipe 15 on its side wall, and a first manual valve 16 is installed on the water inlet pipe 15.
