Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to an EH oil purification device. Background Art

[0002] EH oil is a high-pressure flame-retardant and explosion-proof oil, mainly used for the regulating valve switch of the turbine system. The EH oil system consists of an EH oil tank, an EH oil pump, inlet and outlet doors, a filter, a control block, a relief valve, an accumulator, an EH supply and return oil pipe, an oil cooler, a set of self-circulating oil filtration system and a self-circulating cooling system. The EH oil tank is a container for storing the oil required for the operation of the system, and the EH oil pump is used to adjust the outlet oil pressure. The function of the relief valve is to prevent the oil pressure of the EH oil system from being too high and to ensure that the system pressure is greater than 17 MPa. Chlorine and related hazardous substances exist in the EH oil, so an EH oil purification device is required to work.

[0003] For example, China's authorized patent, announcement number CN218774438U, is a highly reliable EH oil online purification and regeneration device. When the acid removal filter element of the EH oil regeneration device is put into operation, a large pressure difference must be maintained before and after. The two filter cartridges in series structure cannot filter the EH oil in the oil tank at a large flow rate, resulting in the EH oil particle size exceeding the standard many times. In the outlet pressure regulating module of the EH oil circulating pump, an oil pipe is connected to the top of the precision filter cartridge, and a needle valve is installed on the oil pipe to accurately distribute the flow entering the acid removal filter element and the precision filter element, thereby improving the regeneration efficiency of the regeneration device. A seasonal switching valve is installed in the outlet pipe of the original regeneration device, and an oil return bypass door is installed in front of the valve, which is connected to the oil inlet main pipe of the oil cooler through a pipeline.

[0004] The above-mentioned traditional purification equipment performs filtering treatment by adding a cellulose filter element inside the equipment. However, after use, due to the adsorption of the cellulose filter element to a certain extent, the EH oil will still be adsorbed inside the cellulose filter element. During the cleaning process, the adsorbed EH oil is not easy to be discharged, thus affecting the purification effect. Utility Model Content

The EH oil can be discharged through the filter holes 322. When the filter plate 316 is driven to move downward, it can be used to support the cellulose filter element 315 to achieve a supporting effect.

[0025] The driving mechanism includes a motor 317, a bearing 318, a screw 319, a fixing plate 320 and a hole 321.
