Description
Technical Field
[0001] This utility model relates to the field of dehumidifiers for oil storage tanks, and more particularly to a dehumidifier for oil storage tanks. Background Technology
[0002] When the temperature changes, the transformer breathes gas through a desiccant. The desiccant includes a desiccant tank, a top cover, and an oil cup. The top cover is connected to the desiccant tank via a flange on top. The mounting screw hole inside the oil cup connects to a screw extending from inside the desiccant tank. The desiccant tank is filled with desiccant material, and the oil cup contains oil. During the process of the transformer breathing gas through the desiccant, the desiccant absorbs all the moisture in the outside gas. The air passes through the oil cup at the bottom of the desiccant tank and enters the desiccant material inside the tank. After filtration, the clean and dry air enters the oil reservoir capsule. Both the desiccant material and the oil need to be replaced regularly.
[0003] In the prior art, when replacing the moisture-absorbing material in the desiccant, the first step is to loosen the multiple connecting bolts between the top cover and the desiccant. Then, the oil cup at the bottom, which is tightly connected by threads, is loosened by a careful rotation operation so that the used moisture-absorbing material and oil can be removed from the desiccant and replaced.
[0004] During the replacement process described above, the flange of the top cover and the desiccant is connected by multiple bolts, which need to be disassembled one by one. This cumbersome operation greatly reduces the efficiency of the replacement work and is not conducive to the rapid response and efficient execution of maintenance work. This is especially true for large desiccant units, where there are even more bolts and the efficiency is even lower. In addition, for some large desiccant units, one person needs to hold the top cover while another person removes the bolts, making the operation quite difficult. Utility Model Content
[0005] To address the technical problem of low efficiency in replacing moisture-absorbing materials in existing desiccant devices, this invention provides a desiccant for oil storage tanks that allows for quick and convenient disassembly and assembly of the top cover, thereby improving the efficiency of replacing moisture-absorbing materials.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an oil tank desiccant, including a desiccant tank and a top cover. The top cover has symmetrically arranged card seats on its outer circumference. The upper outer circumference of the desiccant tank has a corresponding mounting seat. The mounting seat has a handle rotatably arranged on it. The handle has a hanging ring rotatably arranged on it. The connection position of the hanging ring and the handle is lower than the connection position of the handle and the mounting seat. The hanging ring can be hung on the corresponding card seat.
[0007] This utility model uses a combination of a card holder, a handle, and a hanging ring to connect the top cover and the moisture-absorbing tank via a snap-fit mechanism. Compared to the connecting flange and bolts in the prior art, it eliminates the need to remove and install multiple bolts when disassembling and assembling the top cover, greatly improving disassembly and assembly efficiency. At the same time, it can be operated by one person without the assistance of other personnel, making it convenient to operate and thus improving the efficiency of replacing the moisture-absorbing material.
[0008] Furthermore, the opening end of the moisture-absorbing can is provided with a sealing ring, and after the top cover is installed, the lower part of the top cover is pressed tightly against the sealing ring.
[0009] This invention improves the tightness of the connection between the top cover and the moisture-absorbing tank by setting a sealing ring, preventing air from entering directly from the gap between the two and affecting the moisture absorption effect.
[0010] Furthermore, an upper protective skirt is provided on the lower end face of the top cover. After the top cover is installed, the inner surface of the upper protective skirt is in contact with the outer circumferential surface of the sealing ring.
[0011] This invention effectively prevents dust and rainwater from entering the desiccant through the sealing ring by setting an upper protective skirt, thus further ensuring the drying and filtration effects of the desiccant.
[0012] Furthermore, it also includes an oil cup, with symmetrically arranged locking blocks at the opening of the oil cup. The locking blocks protrude from the outer circumference of the oil cup. The bottom of the moisture-absorbing tank is provided with an installation cavity, which is connected to the interior of the moisture-absorbing tank through a vent hole. A limit block is provided on the inner wall of the installation cavity, and the locking blocks can be locked onto the upper part of the limit block.
[0013] This invention uses a snap-fit connection between the oil cup and the moisture-absorbing canister, which is easier to assemble and disassemble and improves maintenance efficiency compared to threaded connections.
[0014] Furthermore, a guide slope is provided at one end of the limiting block.
[0015] This invention reduces the resistance of the locking block entering the upper part of the limiting block by setting a guide slope, which facilitates installation.
[0016] Furthermore, the bottom of the moisture-absorbing tank is provided with a lower protective skirt, the lower part of which has a trumpet-shaped structure, and the upper cavity of the lower protective skirt is the mounting cavity.
[0017] This invention reduces the amount of rainwater and dust entering the oil cup by incorporating a lower protective skirt, thereby extending the service life of the oil in the oil cup.
[0018] Furthermore, it also includes a vent pipe, which is disposed inside the oil cup. A lower vent plate is provided at the lower end of the vent pipe, and a lower vent hole is provided on the lower vent plate. A connecting screw is vertically disposed on the lower vent plate, and the upper part of the connecting screw is connected to the moisture-absorbing tank. The end face where the upper end of the vent pipe is located abuts against the top surface of the mounting cavity.
[0019] Furthermore, a sealing ring 2 is provided between the upper end face of the vent pipe and the top surface of the mounting cavity.
[0020] This invention effectively prevents air from entering the desiccant directly after entering the oil cup by setting a second sealing ring, thus avoiding affecting the filtration function of the desiccant.
[0021] Furthermore, an upper vent plate is provided inside the vent hole, an upper vent plate is provided on the upper vent plate, and a nut is coaxially provided on the upper vent plate, the nut being sleeved on the upper part of the connecting screw.
[0022] As can be seen from the above technical solutions, this utility model has the following advantages:
[0023] This utility model provides a moisture absorber for an oil tank. Through the cooperation of a mounting bracket, handle, and hanging ring, the top cover and moisture-absorbing tank are connected by a snap-fit mechanism. Compared to the connecting flanges and bolts in existing technologies, this eliminates the need to disassemble and assemble multiple bolts when removing and installing the top cover, greatly improving disassembly and assembly efficiency. Furthermore, it can be operated by one person without assistance, making it convenient and improving the efficiency of replacing the moisture-absorbing material. The addition of a sealing ring enhances the tightness of the connection between the top cover and the moisture-absorbing tank, preventing air from directly entering through gaps and affecting the moisture absorption effect.

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0031] like Figure 1 and Figure 2 As shown, this specific embodiment provides an oil tank desiccant, including a desiccant tank 5 and a top cover 1. A mounting base 2 is symmetrically installed on the outer circumference of the top cover 1 via bolts. In this specific embodiment, two mounting bases 2 are symmetrically arranged. Each mounting base 2 includes a hook protruding outwards. A mounting seat 18 is bolted to a corresponding position on the upper outer circumference of the desiccant tank 5. A handle 4 is rotatably mounted on the mounting seat 18 via a pin. A hanging ring 17 is rotatably mounted on the handle 4. The hanging ring 17 has a C-shaped structure and uses U-bolts. The two ends of the hanging ring 17 are inserted into the holes at both ends of the handle 4. The connection position between the hanging ring 17 and the handle 4 is lower than the connection position between the handle 4 and the mounting seat 18. The hanging ring 17 can be hooked onto the hook of the corresponding mounting base 2.
[0032] This specific embodiment uses the cooperation of the card holder 2, handle 4 and hanging ring 17 to achieve the connection between the top cover 1 and the moisture-absorbing tank 5 by means of a snap fastener. Compared with the connecting flange and bolts in the prior art, especially for large moisture absorbers, it is not necessary to remove and install multiple bolts when disassembling and assembling the top cover 1, which greatly improves the disassembly and assembly efficiency. At the same time, it can be operated by one person without the assistance of other personnel, making it convenient to operate and thus improving the efficiency of replacing moisture-absorbing materials.
[0033] like Figure 2 As shown, in order to ensure the sealing of the snap-fit connection, in this specific embodiment, the opening end of the moisture-absorbing tank 5 is provided with a sealing ring 3. After the top cover 1 is installed, the lower part of the top cover 1 is pressed tightly on the sealing ring 3. With this setting, air is greatly prevented from directly entering from the gap between the two and affecting the moisture absorption effect of the moisture absorber.
[0034] like Figure 2 As shown, in order to prevent rainwater and dust in the air from seeping into the moisture-absorbing tank 5 and entering the oil storage tank, in this specific embodiment, an upper protective skirt 101 is provided on the lower end face of the top cover 1. After the top cover 1 is installed, the inner surface of the upper protective skirt 101 is in contact with the outer circumferential surface of the sealing ring 3. Specifically, the upper protective skirt 101 is a ring-shaped structure to avoid interference with the hanging ring 17 after the outward protrusion design, which would affect the hanging.
[0035] like Figures 2 to 4 As shown, this specific embodiment also includes an oil cup 9. To improve the efficiency of disassembly and assembly of the oil cup 9 and the moisture-absorbing tank 5, a locking block 901 is symmetrically arranged at the opening of the oil cup 9. The locking block 901 protrudes from the outer circumference of the oil cup 9. The bottom of the moisture-absorbing tank 5 is provided with an installation cavity. The installation cavity is connected to the inside of the moisture-absorbing tank 5 through a vent hole 502. A limiting block 8 is provided on the inner wall of the installation cavity. The locking block 901 can be locked onto the upper part of the limiting block 8. Preferably, one end of the limiting block 8 is provided with a guide slope, which makes it easier to install. During installation, the oil cup 9 is rotated so that the locking block 901 gradually rotates from the position without the limiting block 8 to the upper part of the limiting block 8 along the guide slope to achieve locking. During disassembly, it can be reversed. Compared with the prior art, the oil cup 9 and the moisture-absorbing tank 5 are connected by threads, which makes disassembly and assembly convenient and efficient.
[0036] like Figure 2 and Figure 3 As shown, in this specific embodiment, a lower protective skirt 501 is provided at the bottom of the moisture-absorbing tank 5. The lower part of the lower protective skirt 501 has a trumpet-shaped structure, and the upper cavity of the lower protective skirt 501 is an installation cavity. By providing the lower protective skirt 501, rainwater and dust in the air are reduced from entering the oil cup 9, thus extending the service life of the oil in the oil cup 9.
[0037] like Figure 2As shown, this specific embodiment also includes a vent pipe 13, which is disposed inside the oil cup 9. A lower vent plate 12 is provided at the lower end of the vent pipe 13, and a lower vent hole 502 is provided on the lower vent plate 12. A connecting screw is vertically provided on the lower vent plate 12, and the upper part of the connecting screw is connected to the moisture absorption tank 5. The end face of the upper end of the vent pipe 13 abuts against the top surface of the mounting cavity. Preferably, a sealing ring 14 is provided between the end face of the upper end of the vent pipe 13 and the top surface of the mounting cavity. The second 14 can effectively prevent air from entering the oil cup 9 and then directly entering the desiccant 5, thus avoiding affecting the filtration function of this desiccant; specifically, a through hole is provided in the middle of the lower vent plate 12, the connecting bolt 10 passes through the through hole, its head is set outside the lower vent plate 12 and a washer 11 is provided between it and the lower vent plate 12, an upper vent plate 15 is provided inside the vent hole 502, an upper vent hole 502 is provided on the upper vent plate 15, a nut 16 is coaxially provided on the upper vent plate 15, and the nut 16 is sleeved on the upper part of the connecting screw.
[0038] In this specific embodiment, the moisture-absorbing can 5 is composed of a transparent can body 6 and a metal base 7. The transparent can body 6 makes it easy to observe the condition of the moisture-absorbing material inside. The base 7 is composed of a seat part located at the bottom of the can body 6 and mounting parts located on both sides of the can body 6. The seat part includes a lower protective skirt 501, and mounting seats 18 are located on the mounting parts on both sides.
[0039] The working process of this dehumidifier is as follows:
[0040] After installation, the lower vent plate 12 is located inside the oil cup 9. Air enters the oil cup 9 from the outside, then passes through the lower vent plate 12 into the moisture absorption tank 5, and enters the respirator after being dried by the moisture absorption material.
[0041] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:
[0042] 1. By cooperating with the card seat 2, handle 4 and hanging ring 17, the top cover 1 and the moisture-absorbing tank 5 are connected by a snap-fit. Compared with the connecting flange and bolts in the existing technology, it is not necessary to disassemble and install multiple bolts when disassembling and assembling the top cover 1, which greatly improves the disassembly and assembly efficiency. At the same time, one person can operate it without the assistance of other personnel, which is convenient and improves the efficiency of replacing moisture-absorbing materials.
[0043] 2. By setting a sealing ring 3, the tightness of the connection between the top cover 1 and the moisture absorption tank 5 can be improved, preventing air from directly entering from the gap between the two and affecting the moisture absorption effect;
[0044] 3. By setting the upper protective skirt 101, dust and rainwater in the air are effectively prevented from entering the moisture absorption tank 5 through the sealing ring 3, further ensuring the drying and filtration effect of this dehumidifier;
[0045] 4. The oil cup 9 and the moisture absorption canister 5 are connected by a snap-fit mechanism, which is more convenient to disassemble and assemble than a threaded connection, thus improving maintenance efficiency;
[0046] 5. By setting a guide ramp, the resistance of the locking block 901 entering the upper part of the limiting block 8 is reduced, making installation easier;
[0047] 6. By setting the lower protective skirt 501, the amount of rainwater and dust in the air entering the oil cup 9 is reduced, thus extending the service life of the oil in the oil cup 9;
[0048] 7. By setting the sealing ring 14, air is effectively prevented from entering the oil cup 9 and then directly entering the moisture absorption tank 5, thus avoiding affecting the filtration function of this dehumidifier.
[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
