Description

Water cutting runner type quantization sand tank

Technical Field

The utility model relates to the technical field of post-mixing sand adding water cutting, in particular to a water cutting rotary wheel type quantized sand tank.

Background

The ultra-high pressure water jet cutting technology pressurizes water to over 200MPa, and the water is sprayed out through a very small water nozzle (0.3 mm-0.5 mm) to have very high cutting capability. When cutting materials with higher hardness such as metal, stone, ceramic and the like, abrasive materials are required to be mixed in water jet, commonly called "water jet sand", and generally 60-120 mesh garnet or carborundum is adopted.

In the design of a traditional water cutting machine, a large-capacity sand storage tank is arranged at the rear end for storing abrasive materials, and a small-capacity sand supply tank is arranged near a water knife cutting head. The sand storage tank continuously conveys the abrasive materials into the small sand supply tank for buffering through air pressure, the lower end of the small sand supply tank is connected to a fusion cavity near the water jet nozzle through a hose, the abrasive materials are sucked out of the sand supply tank along with negative pressure generated by water jet injection and mixed into the water jet, and the sand is added in a stroke. The lower end of the sand supply tank is provided with a negative pressure cavity, and the size of the negative pressure generated by the water jet is adjusted by adjusting the size of an air hole at the lower end of the sand supply tank. The air outlet holes are large, the negative pressure effect is small, and the mixing amount of the abrasive is small; the air outlet holes are small, the negative pressure effect is strong, and the mixing amount of the abrasive is large. There are other ways to make the adjustment, like adjusting the size of the passage through which the abrasive passes between the canister and the negative pressure chamber.

The above methods for adjusting the abrasive supply amount are fuzzy, cannot be quantitatively controlled, and lack data feedback. When in actual use, the customers usually adjust the air outlet holes to be smaller, and the abrasive amount is larger. And when cutting the work pieces with different materials and different thicknesses, the mixing amount of the abrasive can not be adjusted in time. The abrasive use of water cutting is an optimal sand-water ratio concept. Under the condition of meeting the ratio of the cutting time and the cutting surface requirement, the cutting effect can not be positively influenced by increasing the proportion of the abrasive, and only waste can be caused. Whereas the cost of the abrasive typically accounts for about 50% -70% of the cost of water cutting.

In addition, in terms of data feedback, the conventional sand supply system has no data feedback. The customer does not have a relatively accurate concept of the consumption of abrasive, and only when purchased, the customer can evaluate the approximate consumption over a period of time. Such ambiguous data and extensive management also creates useless waste of abrasive throughout the industry.
