[0022] The technical content of the machine tool water tank self-cleaning cooling system and the application technical effect will be described in detail below through an embodiment shown in the drawings.

[0023] The machine tool water tank self-cleaning cooling system provided by the utility model, as shown in the figure, comprises a primary water tank 8, a lifting pump 2, an oil-water separator 1, a pressure gauge 3, a silt collecting device 4, a flow regulating valve 5, a Venturi nozzle 6 and a connecting pipeline 7. Figure 1 The outlet end of the lifting pump 2 branches into two branches, which are a first output branch and a second output branch, respectively, and the pressure gauge 3 and the silt collecting device 4 are sequentially arranged on the first output branch, and the flow regulating valve 5 and the nozzle 6 are arranged on the second output branch, wherein one of the two branches of the outlet of the lifting pump 2 outputs to a plurality of Venturi nozzles 6, the cutting chips and silt at the bottom of the water tank are stirred and blown away to prevent accumulation, and the other branch transports the cutting chips and silt sucked by the lifting pump 2 into the silt collecting device 4, and the clean cooling liquid filtered by the silt collecting device 4 flows back to the primary water tank 8; wherein the pressure gauge 3 monitors the outlet pressure of the lifting pump 2. The silt collecting device 4 includes but is not limited to a vortex separator, a bag filter, a paper tape filter, a magnetic separator and the like, and a suitable collecting device can be selected according to the water tank configuration and the processing material, and one or more types can be selected; wherein the flow regulating valve 5 adjusts the outlet flow and pressure of the lifting pump 2, adjusts the flow of the Venturi nozzle 6 at the bottom of the water tank, and controls the flushing and blowing degree of the water tank.

[0024] The oil-water separator 1 is arranged at the suction inlet of the lifting pump 2, and the oil-water separator 1 uses the difference in physical affinity between water-based cooling liquid and floating oil to stick the floating oil from the oil liquid mixing area to the oil scraping plate and into the oil collecting box, thereby removing the oil part of the oil liquid mixing area and providing clean cooling liquid for recycling.

[0025] The adjusting valve and the nozzle are connected through the connecting pipeline 7, the connecting pipeline 7 extends into the primary water tank 8 and extends horizontally, and the nozzle 6 is arranged on the horizontally extending connecting pipeline 7.

The nozzle 6 is a Venturi nozzle, and reasonable geometric curve parameters of the Venturi nozzle are adopted to form a large flow cycle and prevent the nozzle from being blocked. During operation, a low-pressure area is formed around the nozzle guide port, and due to the pressure difference in the area, small flow input can achieve large flow output, thereby achieving the purpose of efficiently flushing the chips and silt at the bottom of the water tank and preventing the chips and silt from depositing, thereby providing effective guarantee for subsequent collection. The nozzle is arranged close to the bottom of the primary water tank.
