Embodiment 1

[0033] refer to Figure 1 to Figure 6 For the first embodiment of the present invention, a transformer respirator for improving drying efficiency is provided. This device includes a silicone tank 100, a drive assembly 200 and a cover 100, wherein the silicone tank 100 includes a tank body 101 and a stirring shaft 102, The bottom of the tank body 101 is provided with a through hole 101a, and one end of the stirring shaft 102 passes through the through hole 101a; the driving assembly 200 includes a gear 201 and a screw cap 202, the gear 201 is arranged at the bottom of the tank body 101, and is fixedly connected with the bottom of the stirring shaft 102 , the screw cap 202 is sleeved on the outside of the gear 201 and meshed with the gear 201 ;

[0034] Wherein, the driving assembly 200 also includes a spring 203, which is wound around the bottom of the stirring shaft 102, the center of the spring 203 is fixedly connected with the stirring shaft 102, and the outer end of the spr...

Embodiment 2

[0038] refer to Figure 1 to Figure 6 , is the second embodiment of the present invention, this embodiment is different from the first embodiment in that: the screw cap 202 is ring-shaped, and its upper surface is provided with a plurality of sets of protrusions 202a from the inner to the outer circumference, and the protrusions 202a are hemispherical shape.

[0039] Compared with Embodiment 1, further, the outer wall of the upper end of the tank body 101 is provided with an external thread 101b.

[0040] All the other structures are identical to those of Example 1.

[0041] Specifically, the mutual cooperation between the screw cap 202 and the gear 201 can also remove the tank body 101 as a whole, so as to replace the silica gel particles in the tank body 101; the protrusion 202a on the upper surface of the screw cap 202 is used to increase friction, so that the tank body can be disassembled 101.

[0042]During use, when the silica gel particles in the tank body 101 absorb...

Embodiment 3

[0044] refer to Figure 1 to Figure 8 , is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the cover body 300 is divided into an upper part 301 and a lower part 302, the upper part 301 is square, the lower part 302 is circular, and the diameter of the lower part 302 is The radial diameter is slightly larger than the radial diameter of the tank body 101. The four corners of the upper part 301 are symmetrically provided with threaded holes 301a, and the center of the upper part 301 is provided with an annular groove 301b. Multiple groups of breathing holes 301b - 1 are provided on the annular groove 301b , and the breathing holes 301b - 1 penetrate to the lower part 302 .

[0045] Compared with Embodiment 2, further, the peripheral edge of the lower part 302 is provided with a protrusion 302a, and the inner wall of the annular projection 302a is provided with an internal thread 302a-1, and the cover body 300 ca...

Abstract

The invention discloses a transformer respirator capable of improving drying efficiency which comprises a silica gel tank, a driving assembly and a cover body, the silica gel tank comprises a tank body and a stirring shaft, a through hole is formed in the bottom of the tank body, and one end of the stirring shaft penetrates through the through hole; the driving assembly comprises a gear and a rotary cover, the gear is arranged at the bottom of the tank body and fixedly connected with the bottom of the stirring shaft, and the rotary cover is arranged on the outer side of the gear in a sleeving mode and meshed with the gear; and the cover body is made of stainless steel and is arranged at the top end of the tank body in a matched manner. By arranging the stirring shaft and the spiral fan blades, silica gel particles in the silica gel tank are stirred, the moisture absorption rate is increased, and waste of the silica gel particles is reduced; by arranging the driving assembly, the whole silica gel tank body can be disassembled conveniently, silica gel particles can be replaced more conveniently and efficiently, and meanwhile the stirring shaft can be controlled to rotate through the driving assembly; the cover body is made of stainless steel, so that the transformer respirator is prevented from being oxidized and corroded when exposed outdoors for a long time, and the service life of the transformer respirator is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of transformer respirator, in particular to a transformer respirator with improved drying efficiency. Background technique [0002] Transformer respirator is also called transformer moisture absorber, transformer silica gel tank, transformer desiccant, its function is to absorb the moisture in the oil pillow plastic bag and diaphragm in the air, remove and dry the moisture that enters the transformer oil conservator due to the change of transformer oil temperature The sundries and moisture in the air will prevent the transformer from getting damp and ensure the insulation strength of the transformer oil. [0003] Existing transformer respirator tanks are equipped with a large number of silica gel particles, which can easily cause uneven moisture absorption during use, resulting in waste of silica gel particles, frequent replacement requires more manpower and material resources; at the same time, the top cove...
