The application discloses a kind of leather production wastewater multistage processing system, it is related to wastewater treatment technical field, including jar body, the stirring paddle is rotatably arranged in the jar body, the communicating pipe of several annular distributions is fixedly connected in the jar body bottom, further include, flow guide component, including rotatingly arranged in communicating pipe inside flow guide vane, one end of the flow guide vane is fixedly connected with docking shaft, the docking sleeve is slidably connected in the jar body, the flow guide component further includes the drive mechanism being arranged in the inside of jar body bottom end, the present application uses stirring equipment as the transfer equipment of wastewater precipitation, wastewater after preliminary filtering impurities is fully stirred and mixed with chemical agent, then the mixed wastewater is rapidly guided to the inside of sedimentation tank, i.e. it can be handled every time after leather processing, avoid the unpleasant smell generated due to grease and protein deterioration in wastewater when wastewater is concentrated.

The application relates to the technical field of motor heat dissipation, and discloses a servo motor double-circulation liquid cooling heat dissipation device which comprises a spiral copper pipe wound on the outer surface of a motor winding, the outer surface of the motor winding is provided with a motor shell, one end of the spiral copper pipe is threadedly connected with a no. 1 three-way valve, the other end of the spiral copper pipe is threadedly connected with a no. 2 three-way valve, and the two ends of the no. 1 three-way valve are both threadedly connected with a circulating cooling assembly. The double-circulation cooling assembly is alternately worked to realize continuous and efficient liquid cooling heat dissipation; the cooling liquid filled in the device is driven by a circulating pump to complete heat absorption and heat dissipation circulation, a temperature sensor monitors the cooling liquid temperature in real time and transmits a signal to a controller, when the cooling liquid of one set of circulating cooling assemblies reaches a preset temperature threshold, the controller switches the passage through the three-way valve, starts another set of low-temperature circulating assemblies to continuously absorb heat for the motor winding, and the stopped set of assemblies continuously completes cooling liquid temperature reduction.
