Abstract
Description
Technical Field
[0001] This utility model relates to the field of refining equipment, and in particular to a refining equipment for the production of transformer insulating oil. Background Technology
[0002] As a cooling and insulating material for oil-immersed transformers, insulating oil plays a crucial role in transformer operation. Traditionally, mineral oil is used as transformer insulating oil. However, with the increasing environmental and safety concerns associated with mineral oil, there is an urgent need to find a green, safe, and reliable alternative. Natural, renewable plant-based insulating oils, with their high ignition point, excellent biodegradability, and environmental friendliness, have received widespread attention in recent years.
[0003] In the refining process of vegetable insulating oil, it is inevitable to use a reaction vessel to mix and heat the vegetable insulating oil. However, traditional reaction vessels generally use a motor to drive a stirring rod to rotate and mix the oil. However, the height of the stirring rod is fixed, which results in poor mixing effect and requires a long time to mix evenly, resulting in low efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a refining apparatus for the production of transformer insulating oil, so as to solve the problems mentioned in the background art.

[0008] The first motor is fixedly installed inside the housing;
[0009] A stirring rod is rotatably disposed inside the refining kettle, and the output end of the first motor is connected to the stirring rod via a transmission connection.
[0010] A lifting mechanism is located at the top of the refining vessel and is used to control the lifting and lowering of the shell.

[0015] A lifting plate, which forms a screw drive with the drive rod, is used to control the lifting of the housing.
[0016] Preferably, the lifting mechanism further includes:
[0017] The sliding rod has a groove on the outer wall of the lifting plate, and the end of the sliding rod is fixedly connected to the inner wall of the groove.

Snap-fit holes are provided at equal intervals on both sides of the inner wall of the slide groove. One end of the snap-fit rod is slidably inserted into the inner cavity of the snap-fit hole. The cross-section of the snap-fit rod is L-shaped.
[0019] A compression spring, which is sleeved on the outside of the slide rod;
[0020] A disassembly assembly, which is connected to a locking rod, is used to control the displacement of the locking rod.
[0021] Preferably, the end of the compression spring is fixedly connected to the snap-fit rod, and the snap-fit rod has an L-shaped cross-section.
[0022] Preferably, the disassembly assembly includes:

[0036] 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.
[0037] Example 1
[0038] This utility model provides, for example Figure 1-4 The apparatus shown is a refining device for producing transformer insulating oil, comprising a refining kettle 1, a shell 2, a first motor 3, a stirring rod 4, and a lifting mechanism 5. The shell 2 is located at the top of the refining kettle 1. The first motor 3 is fixedly installed inside the shell 2 and is electrically connected to an external power source via an external switch. The first motor 3 can drive the stirring rod 4 to rotate, thereby stirring and mixing the materials inside the refining kettle 1. The stirring rod 4 is rotatably located inside the refining kettle 1. The output end of the first motor 3 is connected to the stirring rod 4 for transmission. The lifting mechanism 5 is located at the top of the refining kettle 1 and is used to control the lifting of the shell 2.
[0039] The lifting mechanism 5 includes a fixed frame 51, a second motor 52, a drive rod 53, and a lifting plate 54. The fixed frame 51 is fixedly connected to the top of the refining kettle 1. The second motor 52 is fixedly installed on the top of the fixed frame 51. The second motor 52 is electrically connected to an external power supply through an external switch. The second motor 52 can drive the drive rod 53 to rotate in both directions, thereby driving the shell 2 to move back and forth in the vertical direction through the lifting plate 54. This allows the stirring rod 4 to stir at different heights, expanding the stirring range and improving the mixing effect. The end of the drive rod 53 is rotatably set inside the fixed frame 51. The output end of the second motor 52 is connected to the drive rod 53 for transmission. The lifting plate 54 and the drive rod 53 form a screw drive to control the lifting of the shell 2.
[0040] Example 2
[0041] Based on Example 1, such as Figure 3-4 As shown, the lifting mechanism 5 also includes a slide rod 55, a locking rod 56, a compression spring 57, and a disassembly assembly 58. The outer wall of the lifting plate 54 has a groove. The end of the slide rod 55 is fixedly connected to the inner wall of the groove. The locking rod 56 is symmetrically slidably disposed outside the slide rod 55. The outer wall of the housing 2 has a sliding groove. Locking holes are equidistantly spaced on both sides of the inner wall of the sliding groove. One end of the locking rod 56 is slidably inserted into the inner cavity of the locking hole. The cross-section of the locking rod 56 is L-shaped. The compression spring 57 is sleeved on the outside of the slide rod 55. The end of the compression spring 57 is fixedly connected to the snap-fit rod 56. The cross-section of the snap-fit rod 56 is L-shaped. The compression spring 57 is always in a compressed state, which can provide a stable elastic force to the snap-fit rod 56, so that the snap-fit rod 56 can be stably snapped into the snap-fit hole. When the snap-fit rod 56 is snapped into different snap-fit rods 56, the depth of the agitator 4 inside the refining kettle 1 can be adjusted, thereby meeting the requirements of various refining processes. The disassembly assembly 58 is connected to the snap-fit rod 56 and is used to control the displacement of the snap-fit rod 56.
[0042] Furthermore, the disassembly assembly 58 includes a rotating block 581, a push rod 582, a limiting plate 583, a magnet 584, and an iron bar 585. The locking rod 56 has a rotating groove inside, and the rotating block 581 is located inside the rotating groove. One end of the push rod 582 is slidably connected to the lifting plate 54, and the other end of the push rod 582 is fixedly connected to the rotating block 581. The limiting plate 583 is fixedly connected to one end of the push rod 582. The magnet 584 is embedded inside the limiting plate 583, and the iron bar 585 is embedded on both sides of the housing 2. Magnet 584 and iron bar 585 work together, attracting each other to make the limiting plate 583 fit against both sides of the housing 2. This effectively prevents the push rod 582 from driving the locking rod 56 out of the locking hole, ensuring that the locking rod 56 stably connects the housing 2 and the lifting plate 54 for easy use. When disassembly is required, simply rotate the limiting plate 583 to move it away from the housing 2, and then the locking rod 56 can be disassembled by the push rod 582.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
