[0046] In some embodiments, the grinding fluid filtering device further comprises a sensor for detecting a grinding fluid level on the filter cloth.
[0047] The working process of the grinding fluid filtration device provided in this application is as follows:
[0048] The grinding fluid to be filtered enters the inner cavity from the liquid inlet and falls into the pit through the filter cloth. When the grinding fluid on the filter cloth reaches the target liquid level, the controller determines that there are too many foreign particles on the filter cloth and it has no filtering capacity. The unwinding shaft 120 and the winding shaft 320 both rotate, the filter cloth moves, and the filter cloth portion stained with foreign particles and grinding fluid moves to the outside of the inner cavity. The heating structure 230 heats the filter cloth, and the grinding fluid evaporates. As the filter cloth moves forward, the dried filter cloth continues to move, and the foreign particles are peeled off from the filter cloth under the action of the vibration roller 410, and are wound around the winding shaft 320 and rolled up, and the foreign particles fall into the collecting tank 500.
[0049] The grinding fluid filtering device provided by the present application is provided with a drying assembly 200, so that the grinding fluid remaining on the filter cloth evaporates, and the grinding fluid will not drip during the subsequent filter cloth transfer, which is clean and environmentally friendly. A vibration roller 410 is provided to accelerate the separation of the filter cloth and foreign particles.
