Cutting fluid regeneration device

The technical problem to be solved by the invention is to provide a cutting fluid regeneration device. The cutting fluid regeneration device comprises a regeneration box body and a floating oil recovery apparatus. The floating oil recovery apparatus is positioned at the upper end outside the regeneration box body. And a settling tank, a separation tank and a liquid storage tank are sequentially arranged in the regeneration box body from left to right. The upper part of the settling tank is communicated with a floating oil recovery apparatus, the inlet end of the settling tank is communicated with a sewage pipe, and the outlet end of the settling tank is communicated with the inlet end of the separation tank through a first self-priming pump. The outlet end of the separation tank is communicated with the inlet end of the liquid storage tank through a second self-priming pump, the outlet end of the liquid storage tank is communicated with a water outlet pipe, the water outlet pipe is provided with a flow regulator, and liquid output from the outlet end of the liquid storage tank is cutting fluid which can be used after regeneration. The filtering precision can be flexibly adjusted according to actual needs, solid particles and miscellaneous oil of the cutting fluid can be rapidly removed, and the cutting fluid can be recycled. The consumption of the cutting fluid is fundamentallyreduced; cutting fluid discharge is reduced; the waste liquid disposal cost is saved; and the defective rate and rejection rate are reduced.
