[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-3 An emulsion backwashing filtration mechanism shown includes:

[0021] A chassis 1 is provided with a dirty liquid tank 2 and a clean liquid tank 3, and both the dirty liquid tank 2 and the clean liquid tank 3 are provided with a stirrer 22, which stirs the emulsion in the dirty liquid tank 2 and the clean liquid tank 3 to prevent impurities from settling. A residue collection box 5 is further provided between the dirty liquid tank 2 and the clean liquid tank 3, and the residue collection box 5 is connected to the dirty liquid tank 2 through a pipe. A first centrifugal pump 4 is provided on the surface of the pipe. After the emulsion in the dirty liquid tank 2 is pumped out for filtration, the first centrifugal pump 4 can be started to pump the residue in the dirty liquid tank 2 into the residue collection box 5 for collection, so as to facilitate subsequent cleaning.

[0022] A magnetic rod filter 6 is provided with two groups of magnetic rod filters 6, which are respectively arranged in the dirty liquid tank 2 and the clean liquid tank 3, and are used to remove ferromagnetic impurities in the emulsion. The magnetic rod filter 6 uses the effect of the magnetic field to adsorb ferromagnetic impurities in the emulsion. When the emulsion flows through the magnetic rod filter 6, the ferromagnetic impurities therein, such as iron filings, iron powder, etc., will be attracted by the strong magnetic field generated by the magnetic rod and adsorbed on the surface of the magnetic rod. A filter 7 and a plate filter 8 are provided on the surface of the chassis 1 and at the top of the dirty liquid tank 2. The emulsion in the dirty liquid tank 2 is filtered by the plate filter 8 and input into the filter 7, so that the filter 7 performs secondary filtration on the emulsion filtered by the plate filter 8.

[0023] The filter 7 and the plate filter 8 are connected by a pipeline. The surface of the plate filter 8 is connected to a liquid inlet pipe 9, and one end of the liquid inlet pipe 9 is connected to a plurality of first branch pipes 14. One end of the first branch pipe 14 is connected to the dirty liquid tank 2. The middle part of the plate filter 8 is connected to an electric heater 10 for heating the filtered emulsion through a pipeline.

[0024] The surface of the electric heater 10 is connected to a cooler 11 through a pipeline. The surface of the cooler 11 is connected to a drain pipe 12. The surface of the drain pipe 12 is connected to a plurality of second branch pipes 13, and one end of the second branch pipe 13 is connected to the clean liquid tank 3.

[0025] A second centrifugal pump 15 and a pressure gauge 16 are provided on the surfaces of the first branch pipe 14 and the second branch pipe 13. The pressure gauge 16 is installed on the surfaces of the first branch pipe 14 and the second branch pipe 13 for real-time monitoring of the pressure of the emulsion in the branch pipes.

[0026] The surfaces of the first branch pipe 14 and the second branch pipe 13 are further provided with a flange butterfly valve 17 and a check valve 18. By providing the flange butterfly valve 17 on the first branch pipe 14 and the second branch pipe 13, the flow of the emulsion in the branch pipe can be conveniently adjusted, and the check valve 18 can prevent the emulsion from flowing back.

[0027] A return oil magnetic filter 19 is provided on one side of the dirty liquid tank 2, and a liquid level transmitter 20 is provided on the surface of the magnetic rod filter 6. When the emulsion flows back from the working equipment into the dirty liquid tank 2, the iron filings impurities in the emulsion, especially the ferromagnetic impurities, will be magnetically attracted by the return oil magnetic filter 19, thereby filtering the ferromagnetic impurities in the emulsion.

[0028] An electrical cabinet 21 is provided in the chassis 1 , and the first centrifugal pump 4 , magnetic rod filter 6 , filter 7 , plate filter 8 , electric heater 10 , cooler 11 , second centrifugal pump 15 , and return oil magnetic filter 19 are all electrically connected to the electrical cabinet 21 .

[0029] The emulsion backwashing filter mechanism starts the second centrifugal pump 15 on the surface of the first branch pipe 14, and the second centrifugal pump 15 pumps the emulsion in the dirty liquid tank 2 into the liquid inlet pipe 9 through the first branch pipe 14, and is pumped into the plate filter 8 through the liquid inlet pipe 9. The large particles of impurities in the emulsion are intercepted by multiple filter plates in the plate filter 8, and then the filtered emulsion is transported to the filter 7 through the pipeline, and the smaller impurities in the emulsion are filtered for the second time by the filter element with smaller pore structure inside the filter element filter 7. Then, the second-filtered emulsion is transported to the electric heater 10 through the pipeline for The emulsion is heated to intensify the molecular motion and weaken the interaction force between molecules, thereby reducing the viscosity, so that it can flow more smoothly into the cooler 11 for cooling. During the cooling process, the stable structure of the emulsion can be maintained to prevent the emulsion from stratifying during subsequent use. The cooled emulsion is then pumped into the clean liquid tank 3 through the second centrifugal pump 15 on the surface of the second branch pipe 13 and the drain pipe 12 for collection, thereby intercepting large particles of impurities through the plate filter 8 and then performing fine filtration through the filter 7, thereby greatly improving the overall filtration effect of the emulsion.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
