Example Embodiment

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific examples. The present embodiment is implemented in terms of the technical solution of the present invention, and a detailed embodiment and a specific operation process are given, but the scope of the invention is not limited to the following examples.

[0020] Such as figure 1 As shown, the present embodiment provides a solid-liquid mixed oil-water separation device including a slagm module 1, an oil-water separation module 2, a wastewater storage module 3, and a controller (not shown).

[0021] The slagm module 1 includes a slagcase 11, a wastewater inlet 12, a residue outlet 13, a filter separator 14, and a vent line 15. The wastewater inlet 12 and the vent line 15 are all provided at the top end of the slag case 11, and the vent line 15 is connected to the vent 4. The filter separator 14 is disposed in the middle portion of the slag case 11, and the residue ou...

Abstract

The invention relates to a solid-liquid mixed oil-water separation device. The device comprises a deslagging module, an oil-water separation module and a waste water storage module, the waste water storage module comprises a water storage tank and a water pump, the water pump is arranged at a water outlet of the water storage tank, the waste water storage module further comprises a frequency converter and a permanent magnet variable frequency motor, the water pump is connected with the permanent magnet variable frequency motor, and the frequency converter is connected with the permanent magnetvariable frequency motor. Compared with the prior art, the standby of the motor in a low-frequency state is realized by utilizing the sleep function of the frequency converter, so that the frequent starting of the motor is reduced, the mechanical vibration generated when the motor is started can be effectively reduced, and the stable operation of equipment is facilitated; and meanwhile, adverse effects on a power supply network when the device is started are reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a solid-liquid mixed oil-water separation device. Background technique [0002] Sustainable development is an important issue facing today's society. Resource conservation must increase energy use efficiency and be able to recycle and use energy in a sustainable manner. With the improvement of people's living standards, the total amount of domestic wastewater produced by people is increasing, and the sewage treatment plant will make water resources reusable through various processes and steps. The current sewage treatment uses solid-liquid mixed oil-water separation device to initially separate oil pollution, but the existing solid-liquid mixed oil-water separation device has the following problems: 1. Most of the existing devices use low-efficiency common-rate asynchronous motors, and their average Low efficiency, high energy consumption and low power utilization rate; 2. The st...
