The working principle is as follows: the oil inlet joint is connected with a pre-stage coarse filtration device, and the white oil after coarse filtration enters a diversion pipeline through a main pipeline; when a liquid level sensing controller of the fine filtration module monitors that the white oil liquid level in the fine filtration module is lower than a lower limit set value, a two-way solenoid valve is opened, and the white oil in a shunt pipeline flows into the fine filtration module; when the white oil injection reaches the upper limit set value, the two-way electromagnetic valve is closed, the flow can be automatically distributed according to the filtering condition of the fine filtering module, and the normal and efficient operation of the fine filtering operation is ensured to a certain extent. However, the following problems still exist: when the liquid level sensing controller monitors that the white oil liquid level in the fine filtration module reaches an upper limit set value, the two-way solenoid valve cuts off the shunt pipeline, but materials in the section of the shunt pipeline from the solenoid valve position to the fine filtration module continuously enter the fine filtration module, under the influence of the material flow rate, the position of the fine filtration module, the length of the pipeline and the like, the quantity of the materials entering each fine filtration module is still different, so that higher requirements are provided for the installation position of each fine filtration module, and the difficulty is increased for equipment assembly. Based on this, the structure of the existing flow dividing controller used in the white oil filtering system still needs to be improved.
