Description

Technical Field

[0001] The utility model relates to the technical field of insulating oil processing and blending, in particular to a blending device for insulating oil processing. Background Art

[0002] Insulating oil, also known as insulating liquid, is an oily liquid used as an insulating medium in electrical equipment. It has good insulation properties, thermal conductivity and chemical stability. Insulating oil is widely used in power systems, such as transformers, capacitors, cables and other electrical equipment.

[0003] The specific processing steps of insulating oil are as follows:

[0004] 1. Purchase insulating oil raw materials;

[0005] 2. Then filter and remove impurities from the insulating oil raw materials to ensure purity;

[0006] 3. Then, the impurity-removed insulating oil raw materials are subjected to deep processing to form insulating oil finished products;

[0007] 4. Then the treated insulating oil product is tested and inspected. The test items include breakdown voltage, dielectric loss, viscosity, moisture, acid value, etc.;

[0008] 5. Finally, the finished insulating oil product is stored and packaged for later transportation.

[0009] When the insulating oil raw materials are deeply processed, it is generally necessary to add antioxidant additive particles, blend and mix the insulating oil raw materials and antioxidant additive particles together to improve the antioxidant properties of the later insulating oil finished products. Therefore, a blending device for the deep processing of insulating oil raw materials is required.

[0010] At present, the existing blending devices for deep processing of insulating oil raw materials have a problem that the antioxidant additive particles purchased are in granular form and the particle sizes are uneven. If the antioxidant additive particles with too large a particle size are directly added to the blending box, the antioxidant additive particles and the insulating oil raw materials will be blended and mixed unevenly, which will in turn affect the antioxidant properties of the finished product after blending and mixing. This overall reduces the effect of the blending device for deep processing of insulating oil raw materials on the blending and mixing of the antioxidant additive particles and the insulating oil raw materials, and ensures the quality of the insulating oil finished product made later.

[0011] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Reference Figure 1-5 A blending device for insulating oil processing comprises a blending box 1, a filter box 5 is arranged above the blending box 1, a first mixing group 2 and a second mixing group 3 are arranged on the blending box 1, a discharge pipe 11 and a buffer sleeve 7 are arranged on the blending box 1, a discharge valve 12 is arranged on the discharge pipe 11, a feed pipe 4 is arranged on the top of the blending box 1, a feed valve 41 and a telescopic pipe 42 are arranged on the feed pipe 4, a vibration motor 51 and a feeding port 52 are arranged on the filter box 5, a discharge pipe 6 and a slide rod 71 are arranged on the filter box 5, a discharge valve 61 is arranged on the discharge pipe 6, a filter plate 8 and a material guide cover 82 are arranged in the filter box 5, a filter net 81 is arranged on the filter plate 8, and the vibration motor 51 belongs to the YZS series vibration motor.

[0032] In detail, the first mixing group 2 and the second mixing group 3 are both composed of a mixing motor 31, a main shaft 32, and a stirring blade 33. The mixing motor 31 is arranged at the right end of the blending box 1, the motor shaft of the mixing motor 31 is fixed to the main shaft 32, and the stirring blade 33 is arranged on the outer wall of the main shaft 32. The first mixing group 2 and the second mixing group 3 are symmetrically arranged up and down to achieve symmetrical stirring, mixing and blending.

[0033] Furthermore, mixing holes 34 are provided on the stirring blades 33. There are eight stirring blades 33 arranged in a circle, and the mixing holes 34 are arranged in three groups vertically, with each group having seven mixing holes arranged horizontally. When the stirring blades 33 rotate at a high speed, the antioxidant additive particles and the insulating oil raw materials will pass through each mixing hole 34, further increasing the effective contact area of ​​the mixing.

[0034] Furthermore, the upper and lower ends of the telescopic tube 42 are respectively connected to the filter box 5 and the feed pipe 4. The telescopic tube 42 is a stainless steel bellows structure, which can perform vertical telescopic deformation along with the vibration of the filter box 5, but does not affect the feed.

[0035] The slide bar 71 is slidably connected in the buffer sleeve 7 , and a buffer spring 72 is provided between the slide bar 71 and the inner cavity of the buffer sleeve 7 , and the buffer spring 72 realizes vibration buffering of the vibrating filter material box 5 .

[0036] In more detail, the filter plate 8 is tilted toward the discharge pipe 6, and the filter net 81 is embedded in the filter plate 8. The top-view cross-section of the filter net 81 is not larger than the top-view cross-section of the upper opening of the material guide cover 82, ensuring that the filtered antioxidant additive particles that meet the particle size will pass through the filter net 81 and fall into the material guide cover 82 to avoid omission.

[0037] In general, an inclined surface 13 is provided on the bottom end wall of the inner cavity of the blending box 1, and the inclined surface 13 is inclined toward the discharge pipe 11, thereby improving the discharge efficiency of the finished product in the later stage.

[0038] Finally, a block 73 is provided on the inner wall of the upper end of the sliding cavity of the buffer sleeve 7, and a slip ring 711 is provided on the outer wall of the sliding rod 71. Both the block 73 and the slip ring 711 are made of elastic fluororubber, which is impact-resistant and durable. When the filter box 5 vibrates, it will drive the sliding rod 71 to slide vertically along the buffer sleeve 7, and the block 73 prevents the slip ring 711 from slipping out of the buffer sleeve 7.

[0039] Working method: start the vibration motor 51 to drive the filter box 5 to vibrate vertically as a whole, and then put the antioxidant additive particles into the filter plate 8 through the feeding port 52. The antioxidant additive particles fall on the filter plate 8. The filter plate 8 that is vibrating all the time will shake the antioxidant additive particles apart, and at the same time will slide to the lower left. When passing through the filter net 81, the antioxidant additive particles that meet the particle size will pass through the filter net 81 and enter the blending box 1 through the telescopic tube 42 and the feed pipe 4. At this time, the antioxidant additive particles that meet the particle size will be stirred, blended and mixed with the insulating oil raw material preset in the blending box 1 by the first mixing group 2 and the second mixing group 3. Finally, open the discharge valve 12 to discharge the finished product through the discharge pipe 11, and the antioxidant additive particles with large particle size will accumulate at the discharge pipe 6, and can be discharged by opening the discharge valve 61 later.

[0040] The above operation improves the effect of the blending device used for deep processing of insulating oil raw materials on blending and mixing antioxidant additive particles with insulating oil raw materials, thereby ensuring the quality of the insulating oil finished product produced later.

[0041] In addition, combined with the mixing hole 34, the symmetrical first mixing group 2 and the second mixing group 3 can effectively and comprehensively stir, blend and mix the antioxidant additive particles and the insulating oil raw material, further improving the blending effect of the blending box on the antioxidant additive particles and the insulating oil raw material.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
