Description
Technical Field
[0001] The utility model belongs to the technical field of transformer equipment, and in particular relates to a desiccant which is easy to install. Background Art
[0002] The desiccant is a device installed at the end of the pipe connected to the oil pillow, also known as a transformer desiccant or transformer respirator. It is used to absorb moisture from the air that enters the oil pillow plastic bag and diaphragm, as well as to remove debris and moisture from the air that enters the transformer. When the transformer oil temperature rises, the volume increases due to the expansion of the transformer oil, so the space on the oil pillow becomes smaller and the pressure rises, and the air will be discharged through the desiccant. When the oil temperature drops, the volume decreases due to the contraction of the oil, and negative pressure is formed in the oil pillow, and the outside air will be sucked in.
[0003] When the silica gel in the desiccant changes color by more than two-thirds, the silica gel needs to be replaced and the oil cup of the desiccant needs to be cleaned. After cleaning, the desiccant can be installed on the pipeline again. This process involves removing or installing the entire desiccant by unscrewing multiple bolts on the desiccant and pipeline flange. Since the bolts have no protective devices, they will rust over time due to erosion by wind and rain, making disassembly and assembly difficult. Utility Model Content

DETAILED DESCRIPTION
[0020] In order to better understand the purpose, structure and function of the present invention, the present invention is described clearly and completely below in conjunction with the accompanying drawings.
[0021] like Figure 1-Figure 3 The desiccant shown is easy to install, and includes: a flange 1, a connecting cover 2, a tank body 3 and an oil cup 4; the upper part of the flange 1 is used to connect the oil pillow, and the lower part is fixedly connected to the connecting cover 2. In this embodiment, the flange 1 and the connecting cover 2 can be welded into one or fixedly connected by bolts. The connecting cover 2 is located at the upper part of the tank body 3 and is detachably connected to the tank body 3. When the desiccant needs to be cleaned, the tank body 3 and the connecting cover 2 can be separated without unscrewing the bolts on the flange 1 that have been corroded by wind and rain. The inside of the tank body 3 is used to fill silica gel, and a handle 5 is provided on the outer wall. The bottom is detachably connected to the oil cup 4. The bottom of the tank body 3 is not through, and a bottom plate is provided. The bottom plate is provided with a number of small holes with a diameter smaller than that of the silica gel, so that moisture and air in the transformer can enter and exit between the tank body 3 and the oil cup 4. Since the tank body 3 is generally made of glass, a handle 5 is provided for the staff to hold the tank body 3 when disassembling and assembling, so as to prevent the tank body 3 from falling and breaking; further, an anti-slip sleeve 10 is provided on the outer wall of the tank body 3, and the anti-slip sleeve 10 is located below the handle 5. The anti-slip sleeve 10 increases the static friction between the staff's hand and the tank body 3. When the handle 5 is damaged, the staff holds the anti-slip sleeve 10 to disassemble and assemble the tank body 3. The material of the anti-slip sleeve 10 is rubber, and a plurality of raised anti-slip particles are provided on the outer wall.
[0022] In one possible implementation, a first internal thread is provided on the inner wall of the connecting cover 2, and a first external thread (not shown in the figure) is provided on the upper part of the outer wall of the tank body 3 and meshed with the first internal thread. The connecting cover 2 and the tank body 3 are detachably connected via the first internal thread and the first external thread. During disassembly and assembly, since the connecting cover 2 is fixedly connected to the flange 1, the tank body 3 can be separated from the connecting cover 2 or installed as a whole by simply twisting the tank body 3. In order to prevent air leakage between the connecting cover 2 and the tank body 3, a raw tape is wrapped around the outside of the second external thread 11.
[0023] In another possible implementation, a connecting block 6 is provided on the upper portion of the outer wall of the tank body 3, and a fixing groove matching the connecting block 6 is provided on the inner wall of the connecting cover 2; the fixing groove includes a first vertical portion 7, a horizontal portion 8 and a second vertical portion 9; the first vertical portion 7 extends upward from the bottom of the connecting cover 2 and is connected to one end of the horizontal portion 8, the other end of the horizontal portion 8 is connected to the upper end of the second vertical portion 9, and the lower end of the second vertical portion 9 is located above the lower end of the first vertical portion 7, that is, the second vertical portion 9 does not penetrate downward through the connecting cover 2. During installation, the staff member holds the handle 5 and moves the tank body 3 upward, so that the connecting block 6 slides in the first vertical part 7 until the upper part of the connecting block 6 contacts the top of the first vertical part 7; then the staff member rotates the tank body 3 to make the connecting block 6 slide in the horizontal part 8 until it slides to the position where the horizontal part 8 is connected to the second vertical part 9; finally, the tank body 3 is pulled downward to make the bottom of the connecting block 6 contact the bottom of the second vertical part 9 to complete the installation of the tank body 3; the installation process is simple, and the burden of the staff member is reduced without tightening the bolts, and the installation of the tank body 3 can be completed without tools such as screwdrivers. The disassembly process is the reverse process of the installation process. In order to prevent air leakage between the connecting cover 2 and the tank body 3, a sealing layer adapted to the outer wall of the tank body 3 is provided inside the connecting cover 2 for sealing.
[0024] The bottom of the tank body 3 is detachably connected to the oil cup 4, so that the oil cup 4 can be easily removed for cleaning. Specifically, a second external thread 11 is provided on the upper part of the outer wall of the tank body 3, and a second internal thread 12 meshing with the second external thread 11 is provided on the inner wall of the oil cup 4. The oil cup 4 can be separated from the tank body 3 or installed as one by twisting the oil cup 4. A plurality of breathing holes 15 are provided on the upper side wall of the oil cup 4, which are used to inhale the outside air or exhale the air in the transformer. The breathing holes 15 are provided with a filter to prevent dust from entering the oil cup 4. A connecting portion 14 corresponding to the breathing hole 15 is also provided on the top of the oil cup 4. On the one hand, it is used to connect with the tank body 3, that is, the inner wall of the connecting portion 14 is provided with a second internal thread 12; on the other hand, the breathing hole 15 is protected to prevent impurities from entering the breathing hole 15 to a certain extent. The side wall of the oil cup 4 is also provided with scale lines 13, specifically including an upper scale line 13 and a lower scale line 13, which serve as a reminder for the operator filling the transformer oil to avoid the malfunction of the desiccant caused by too low or too high oil level.
