Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, specifically a waterproof coating spraying device for transformer production. Background Technology

[0002] A transformer is a static electrical device used to change the voltage level of alternating current. During the production process of a transformer, a waterproof coating is sprayed onto its outer surface. This not only protects the equipment from moisture but also enhances its weather resistance and service life. However, most existing spraying equipment uses manual spraying, and the paint sprayed during the process is more or less harmful to the human body. In addition, manual spraying is prone to uneven coating on the outer surface of the transformer.

[0003] To address the aforementioned issues, CN215964388U discloses a "Spraying Device for Transformer Production," which places the spraying unit inside the spraying box to reduce harm to personnel during the spraying process. By incorporating a rotating unit that drives the transformer, spraying occurs simultaneously with the transformer's rotation, thereby improving the quality of the coating. However, this device still has certain drawbacks in practical use. For example, although the spraying unit is located inside the spraying box, exhaust gases generated during the spraying process still remain inside. Therefore, when the transformer is removed from the spraying box, the exhaust gases are still released into the air, polluting the environment and posing a health risk to workers. Furthermore, the coating box of this device is a single unit, making it impossible to clean and replace the coating inside, thus failing to meet the spraying requirements of different coatings for transformers.

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-8As shown, a waterproof coating spraying device for transformer production includes: a spraying box 1, a paint tank 101 is provided on one side of the outer end of the spraying box 1, a can cover 102 is provided on the top of the paint tank 101, and a purification component is provided on the top of the spraying box 1 for purifying the exhaust gas generated during spraying. The purification component includes: an exhaust pipe 2, an exhaust fan 201, a purification frame 202 and activated carbon particles 203. A disassembly and assembly component is provided between the can cover 102 and the paint tank 101 for disassembling and assembling the can cover 102. The disassembly and assembly component includes: a positioning block 5, a positioning groove 501, a threaded hole 502, a through hole 503 and a bolt 504.

[0025] The spraying box 1 is connected to an exhaust pipe 2 at the top. A purification frame 202 is installed inside the exhaust pipe 2. An exhaust fan 201 is installed on the top of the purification frame 202. The purification frame 202 is filled with activated carbon particles 203. When the transformer inside the spraying box 1 is sprayed, odorous exhaust gas is generated. At this time, the exhaust gas in the spraying box 1 is extracted by the exhaust fan 201 and the exhaust pipe 2. When the exhaust gas is discharged from the exhaust pipe 2, it will pass through the purification frame 202 and be purified by the activated carbon particles 203, thereby preventing the exhaust gas from being directly discharged into the air.

[0026] The purification frame 202 is connected to an installation plate 3 on the outside. The installation plate 3 has a circular connecting groove 301. The top of the exhaust pipe 2 is provided with a disassembly pipe 302. The bottom of the disassembly pipe 302 is connected to a connecting block 303. The outer side of the connecting block 303 is threaded to the connecting groove 301. When it is necessary to replace the activated carbon particles 203 inside the purification frame 202, rotate the disassembly pipe 302 to drive the connecting block 303 to rotate until the connecting block 303 rotates out from the connecting groove 301. Then, separate the disassembly pipe 302 from the purification frame 202. Then, move the purification frame 202 upward through the handle 402 until the purification frame 202 drives the insertion block 4 to slide out from the slot 401 and separate from the exhaust pipe 2. At this time, the activated carbon particles 203 inside the purification frame 202 can be replaced.

[0027] The mounting plate 3 has inserts 4 on both sides of its bottom, and slots 401 are provided on both sides of the top of the exhaust pipe 2. A handle 402 is installed inside the purification frame 202. The bottom of the spray box 1 has multiple air inlets, and a filter 403 is installed inside each air inlet. When installing the purification frame 202, the purification frame 202 is placed inside the exhaust pipe, and the inserts 4 are placed inside the slots 401. Then, the disassembly pipe 302 is placed on top of the purification frame 202, and the disassembly pipe 302 and the connecting block 303 are rotated until the connecting block 303 is rotated into the connecting groove 301 and threadedly connected to it. Thus, the disassembly pipe 302 is installed on top of the purification frame 202. The air inlets are used to ensure that air outside the spray box 1 can enter the spray box 1, and the filter 403 is used to filter dust from the air entering from the air inlets.

[0028] The bottom of the can lid 102 is connected to positioning blocks 5 on both sides, and the top of the paint can 101 is provided with positioning grooves 501 on both sides. The outer end of the positioning block 5 is provided with a threaded hole 502, and the outer end of the paint can 101 is provided with through holes 503 on both sides. The through holes 503 are provided with bolts 504 that are threaded to the threaded holes 502. When it is necessary to clean the inside of the paint can 101, the bolts 504 are turned out from the threaded holes 502 and through holes 503, and then the can lid 102 is moved upward until the rotating rod 601 and the stirring rod 602 are removed from the inside of the paint can 101. This makes it easier to clean the inside of the paint can 101, so that the paint can 101 can store different paints for spraying transformers.

[0029] The can lid 102 is equipped with a motor 6 on top, and a rotating rod 601 is connected to the bottom of the motor 6. Multiple stirring rods 602 are connected to both sides of the outer end of the rotating rod 601. A discharge pipe 603 is connected to one side of the outer end of the paint can 101, and a control valve is installed on the outside of the discharge pipe 603. A feed pipe 604 is connected to one side of the top of the can lid 102. When cleaning the inside of the paint can 101, the control valve can be opened to allow the wastewater in the paint can 101 to be discharged from the discharge pipe 603. When the paint can 101 contains paint, the rotating rod 601 driven by the motor 6 can rotate the stirring rods 602, and then the stirring rods 602 can stir the paint to prevent the paint from solidifying.

[0030] An air pump 7 is installed between the paint tank 101 and the spraying box 1. One side of the outer end of the air pump 7 is connected to a suction pipe, and the other side of the outer end of the air pump 7 is connected to a delivery pipe 701. A diversion pipe 702 is installed on one side of the inner wall of the spraying box 1, and multiple spray heads 703 are installed on one side of the outer end of the diversion pipe 702. When using the device, the box door connected to the inner wall of the spraying box 1 by a hinge is rotated open, the transformer to be sprayed is placed on top of the rotating disk 801, and then the box door is rotated closed. The paint inside the paint tank 101 is then transported to the delivery pipe 701 through the suction pipe by the air pump 7, and then the paint is transported to the diversion pipe 702 and the spray heads 703 through the delivery pipe 701. Finally, the paint is sprayed out to the outside of the transformer through the spray heads 703.

[0031] The bottom of the spray box 1 is equipped with a servo motor 8, and the top of the servo motor 8 is connected to a rotating disk 801 via a motor shaft. A drying lamp 802 is installed on one side of the inner wall of the spray box 1. When the spray head 703 sprays the transformer, the servo motor 8 can drive the motor shaft to rotate the rotating disk 801 and the transformer, thereby adjusting the spraying angle of the transformer and spraying the outside of the transformer. The coating on the outside of the transformer can be dried quickly by the drying lamp 802.

[0032] Working principle:

[0033] When using this device, the door on one side of the inner wall of the spray box 1, which is connected by a hinge, is rotated open. The transformer to be sprayed is then placed on top of the rotating disk 801. The door is then rotated closed. The paint inside the paint tank 101 is then transported to the conveying pipe 701 via the suction pipe using the air pump 7. The paint is then transported to the distribution pipe 702 and the spray head 703 via the conveying pipe 701. Finally, the paint is sprayed out onto the outside of the transformer via the spray head 703. At this time, the rotating disk 801 and the transformer can be rotated by the servo motor 8, which drives the motor shaft to adjust the spraying angle of the transformer, thereby achieving full spraying of the outside of the transformer. The paint on the outside of the transformer can be dried by the drying lamp 802. The coating is dried quickly, and the exhaust gas in the spray box 1 can be extracted by the exhaust fan 201 and exhaust pipe 2 during the coating process. When the exhaust gas is discharged from the exhaust pipe 2, it will pass through the purification frame 202 and be purified by the activated carbon particles 203, thus preventing the exhaust gas from being directly discharged into the air. When it is necessary to clean the inside of the coating tank 101, the bolt 504 is turned out from the threaded hole 502 and the through hole 503, and then the tank cover 102 is moved upward until the rotating rod 601 and the stirring rod 602 are removed from the inside of the coating tank 101. At this time, it is convenient to clean the inside of the coating tank 101, so that the coating tank 101 can store different coatings for coating the transformer.
