[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A mixing reactor for mixing plant insulating oil includes a filter cylinder 1, a reactor body 2 fixedly mounted on the top of the filter cylinder 1, a mixing mechanism for mixing plant insulating oil raw materials is provided inside the reactor body 2, a first discharge pipe 10 is connected to the bottom of the reactor body 2, a first discharge valve 11 is provided on the first discharge pipe 10, a mounting base 12 is threadedly installed on the bottom of the first discharge valve 11, a filter element 13 for filtering impurities in the plant insulating oil is provided inside the mounting base 12, and the top of the filter element 13 is in contact with the bottom of the first discharge pipe 10.

[0026] It should be noted that the installation base 12 improves the convenience of installing and removing the filter element 13. In addition, when the filter element 13 is installed in the installation base 12, the filter element 13 contacts the inner wall of the installation base 12, which serves to position the filter element 13.

[0027] A support mesh plate 16 is fixedly installed on the inner wall of the filter cylinder 1. Filter paper 17 for filtering impurities in plant insulating oil is laid on the top of the support mesh plate 16. A clamping mechanism for pressing and fixing the filter paper 17 is provided inside the filter cylinder 1.

[0028] It should be noted that the support mesh plate 16 serves to support the filter paper 17. The support mesh plate 16 is made of stainless steel, which is corrosion-resistant and has strong pressure resistance. The filtration accuracy of the filter element 13 and the filter paper 17 is set to 4μm, which is used to intercept particles and colloidal substances.

[0029] In an optional embodiment: the stirring and mixing mechanism includes a drive motor 3, a rotating rod 4 and stirring blades 5. The drive motor 3 is fixedly installed on the top of the vessel body 2. The rotating rod 4 is fixedly connected to the output shaft of the drive motor 3 through a coupling. Multiple sets of stirring blades 5 are provided, and multiple sets of stirring blades 5 are fixedly connected to the surface of the rotating rod 4.

[0030] It should be noted that the drive motor 3 is a YP2-160L-6 model variable frequency motor, which has the characteristics of no speed reducer, precise speed regulation, and compatibility with PLC automation control. Through the cooperation of drive motor 3, rotating rod 4 and stirring blade 5, the plant insulating oil raw material is stirred and mixed, so that the plant insulating oil raw material can achieve a uniform effect.

[0031] In an optional embodiment: a positioning frame 7 for positioning the rotating rod 4 is fixedly installed on the inner wall of the vessel body 2, and the rotating rod 4 is movably installed in the positioning frame 7.

[0032] It should be noted that the positioning frame 7 serves to position the rotating rod 4, enabling the rotating rod 4 to be stably rotated and installed within the positioning frame 7.

[0033] In an optional embodiment: each of the multiple sets of stirring blades 5 has a through hole 6.

[0034] It should be noted that by setting the through hole 6, the presence of the through hole 6 causes the stirring blade 5 to generate local eddies when rotating, breaking the laminar flow state of the high viscosity insulating oil, accelerating the dispersion and fusion of oil and additives, avoiding local uneven concentration, and the through hole 6 can reduce the stirring torque, reduce the load on the drive motor 3, and significantly save energy in long-term operation.

[0035] In an optional embodiment: the pressing mechanism includes a pressing ring 19 and a lead screw 25. A first mounting block 14 is fixedly installed on the inner wall of the filter cylinder 1. The lead screw 25 is threadedly installed in the first mounting block 14. The lower end of the lead screw 25 is movably installed on the top of the pressing ring 19. A rubber pad 20 is provided at the bottom of the pressing ring 19. The rubber pad 20 is pressed against the filter paper 17.

[0036] It should be noted that by cooperating with the screw 25, the screw 25 is turned so that when it moves downward within the first mounting block 14, it drives the screw 19 and the rubber pad 20 to move downward, so that the screw 19 is pressed against the filter paper 17 by the rubber pad 20, thereby pressing and fixing the filter paper 17 and improving the stability of the filter paper 17.

[0037] In an optional embodiment: a second mounting block 15, which is symmetrical to the first mounting block 14, is fixedly installed on the inner wall of the filter cartridge 1, and a positioning rod 18 is fixedly installed on the top of the pressure ring 19, and the positioning rod 18 is movably inserted into the second mounting block 15.

[0038] It should be noted that the positioning rod 18 serves as a guide and positioner for the pressure ring 19, enabling the pressure ring 19 to move vertically stably.

[0039] In an optional embodiment: the bottom of the filter cylinder 1 is connected to a second discharge pipe 21, and a second discharge valve 22 is provided on the second discharge pipe 21.

[0040] It should be noted that, through the cooperation of the second discharge pipe 21 and the second discharge valve 22, the plant insulating oil falling into the bottom of the filter cylinder 1 can be discharged and collected by opening the second discharge valve 22; in addition, a material inlet 8 is provided on the side of the filter cylinder 1, and a sealing door 9 for sealing the material inlet 8 is fixedly installed on the vessel body 2. After opening the sealing door 9, the first discharge valve 11 can be opened or closed, or the filter element 13 and filter paper 17 can be replaced.

[0041] In an optional embodiment: the top of the vessel body 2 is connected to a feed hopper 23, and a sealing cover 24 is sealed on the feed hopper 23.

[0042] It should be noted that, with the setting of the feed hopper 23, the plant insulating oil raw material can be added into the reactor body 2 through the feed hopper 23 after the sealing cover 24 is opened. The sealing cover 24 is used to seal the feed hopper 23 to prevent foreign matter from entering.

[0043] In practical use, the plant insulating oil raw material is first added into the reactor body 2 through the feed hopper 23. The drive motor 3 is started and the output shaft of the drive motor 3 rotates, which drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, it drives the stirring blade 5 to rotate. When the stirring blade 5 rotates, the plant insulating oil raw material is stirred and mixed.

[0044] After mixing the vegetable insulating oil, open the sealing door 9 and open the first discharge valve 11 and the second discharge valve 22, so that the vegetable insulating oil in the reactor body 2 is discharged from the filter cylinder 1 through the first discharge pipe 10. When the vegetable insulating oil is discharged from the reactor body 2, the impurities in the vegetable insulating oil can be filtered through the filter element 13. The filtered impurities are stored in the filter element 13. The filtered vegetable insulating oil can fall onto the filter paper 17. After being filtered again by the filter paper 17, the vegetable insulating oil falls to the bottom of the filter cylinder 1 and is discharged and collected through the second discharge pipe 21.

[0045] When the filter element 13 needs to be replaced, the mounting base 12 can be removed from the bottom of the first discharge pipe 10 by twisting the mounting base 12. The vegetable insulating oil can still be filtered through the first discharge pipe 10 and the filter paper 17, avoiding production interruption, ensuring continuous operation of the reactor, and improving the filtration efficiency of the vegetable insulating oil.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
