Description

Technical Field

[0001] This utility model relates to the technical field of transformer production equipment, and in particular to a powder spraying system for the outer wall of a transformer corrugated oil tank. Background Technology

[0002] A transformer corrugated oil tank is a fully sealed tank whose main functions are heat dissipation and expansion and contraction, while ensuring that the transformer oil is completely isolated from the air. Through its special corrugated plate wall design, the corrugated oil tank automatically expands and contracts with changes in ambient temperature and load, ensuring that the transformer oil is completely isolated from the air, thus requiring no maintenance during the transformer's lifespan.

[0003] Existing transformer corrugated oil tanks have the following drawbacks during the production process: After the transformer corrugated oil tank is extruded and shaped, it needs to be powder-coated inside and out to improve its corrosion resistance and other properties. However, when powder-coating the outer wall of the corrugated oil tank, due to the special corrugated structure and the large depth between the corrugated plates, traditional powder-coating equipment is not convenient for comprehensively powder-coating the surface of the corrugated plates. Therefore, we propose a powder-coating system for the outer wall of transformer corrugated oil tanks. Utility Model Content

[0004] The main purpose of this utility model is to provide a powder coating system for the outer wall of a transformer corrugated oil tank. By using a spraying mechanism installed at the powder discharge end of the powder hopper, the surface of the corrugated plate can be uniformly powder coated, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A powder coating system for the outer wall of a transformer corrugated oil tank includes a powder hopper and a coating mechanism. The powder hopper discharge end is equipped with the coating mechanism, which includes a handle, a vertical plate A, a vertical plate B, a feed pipe, a nozzle A, an insert plate, and a nozzle B. The vertical plate A and the vertical plate B are fixedly connected to both sides of the handle. The feed pipe is embedded inside both the vertical plate A and the vertical plate B. The nozzle A is installed on one side of the feed pipe located on the surface of the vertical plate A. The insert plate is movably connected to the surface of the vertical plate B, and nozzles B are installed on both sides of the insert plate. The feed end of the nozzle B is connected to the feed pipe.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the insert plate and the vertical plate B. The adjustment mechanism includes a groove, a slider, a connecting pipe, a corrugated pipe, bolts, and nuts. A groove is formed on the surface of the vertical plate B facing the insert plate, and a slider is slidably connected inside the groove. The end of the vertical plate is connected to the surface of the slider, and a connecting pipe is provided through the slider. The connecting pipes are connected to each other and to the feeding pipe via corrugated pipes. Bolts extending to the surface of the vertical plate B are fixedly connected to the surface of the slider, and nuts are screwed onto the bolt surfaces. The slider can slide along the groove... The horizontal translation inside the slot drives the movement of the insert plate. The connecting pipes are connected by corrugated pipes, which not only ensures the normal conveying of powder, but also allows the slider to move normally. During surface spraying, the position of the insert plate and the spacing between the insert plates can be adjusted according to the spacing of the corrugated plates on the surface of the corrugated oil tank of different specifications. Loosening the nut allows the slider to slide along the groove to adjust the spacing between the insert plates. After reaching the appropriate spacing, tightening the nut uses the friction between the nut and the surface of the vertical plate B to fix the position of the insert plate. It is flexible to use, easy to adjust, and suitable for the production and processing of corrugated oil tanks of different specifications.

[0008] Furthermore, a conveying pipe connected to the inside of the handle is installed at the discharge end inside the powder hopper. One end of the conveying pipe is connected to the pump assembly inside the powder hopper. After being pressurized by the pump assembly inside the powder hopper, the powder is conveyed to the feeding pipe by the conveying pipe.

[0009] Furthermore, a three-way valve is installed at the connection between the conveying pipe and the feeding pipe; the three-way valve structure can adjust the direction of powder discharge, thereby meeting different spraying requirements.

[0010] Furthermore, a through groove is provided on one side of the surface of the upright plate B, and the bolt passes through the inside of the through groove. A rubber ring is glued to the side of the nut facing the surface of the upright plate B. When the slider moves, the bolt moves along the through groove without affecting the adjustment of the position of the insert plate. The rubber ring structure can increase the friction between the nut and the surface of the upright plate B.

[0011] Compared with the prior art, this utility model has the following advantages: A handle is provided at the discharge end of the powder bucket, and vertical plates A and B are provided on the surface of the handle. A three-way valve adjusts the powder input to either vertical plate A or vertical plate B. During ordinary spraying operations on the surface of a transformer corrugated oil tank, the powder is sprayed from nozzle A on the surface of vertical plate A, resulting in a larger spray area and facilitating rapid spraying over a large area. When spraying the corrugated plates on the surface of the corrugated oil tank, the three-way valve is adjusted so that the powder is sprayed from one side of vertical plate B. After being transported into the interior of vertical plate B, the powder enters the insert plate and is sprayed out from nozzle B. Before operation, the position of the insert plate can be adjusted so that it can be inserted precisely between adjacent corrugated plates. During spraying, the insert plate is inserted between the corrugated plates, and the powder is then sprayed out from the nozzle. The B-type spray can evenly spray onto different positions on the corrugated plate surface, unaffected by the depth between the corrugated plates, thus improving the efficiency and uniformity of spraying on the outer wall of the corrugated oil tank. The slider can move horizontally along the inside of the slide groove, driving the movement of the insert plate. The connecting pipes are connected by corrugated pipes, ensuring the normal conveying of powder while allowing the slider to move normally. During surface spraying, the position of the insert plate and the spacing between the insert plates can be adjusted according to the spacing of the corrugated plates on the surface of the corrugated oil tank of different specifications. Loosening the nut allows the slider to slide along the slide groove to adjust the spacing between the insert plates. After reaching the appropriate spacing, tightening the nut uses the friction between the nut and the surface of the vertical plate B to fix the position of the insert plate. It is flexible in use, easy to adjust, and suitable for the production and processing of corrugated oil tanks of different specifications. Attached Figure Description

The coating mechanism 2 includes a handle 201, a vertical plate A203, a vertical plate B204, a feed pipe 205, a nozzle A206, an insert plate 207, and a nozzle B208. The vertical plate A203 and the vertical plate B204 are fixedly connected to both sides of the surface of the handle 201, respectively. The feed pipe 205 is embedded inside both the vertical plate A203 and the vertical plate B204. The nozzle A206 is installed on one side of the surface of the feed pipe 205 located on the surface of the vertical plate A203. The insert plate 207 is movably connected to the surface of the vertical plate B204, and the nozzles B208 are installed on both sides of the surface of the insert plate 207. The feed end of the nozzle B208 is connected to the feed pipe 205.

[0018] The system also includes an adjustment mechanism 3. An adjustment mechanism 3 is provided at the connection between the insert plate 207 and the upright plate B204. The adjustment mechanism 3 includes a groove 301, a slider 302, a connecting pipe 303, a corrugated pipe 304, a bolt 306, and a nut 307. A groove 301 is formed on the surface of the upright plate B204 facing the insert plate 207, and a slider 302 is slidably connected inside the groove 301. The end of the upright plate is connected to the surface of the slider 302, and a connecting pipe 303 is provided through each slider 302. The connecting pipes 303 are connected to each other and to the feeding pipe 205 via corrugated pipes 304. Bolts 306 extending to the surface of the upright plate B204 are fixedly connected to the surface of the slider 302, and the bolts 306 are screwed onto the surface of the slider. The device includes a nut 307; the slider 302 can move horizontally along the inside of the slide groove 301, driving the movement of the insert plate 207. The connecting pipes 303 are connected by a corrugated pipe 304, which ensures the normal conveying of powder and allows the slider 302 to move normally. During surface spraying, the position of the insert plate 207 and the spacing between the insert plates 207 can be adjusted according to the spacing of the corrugated plates on the surface of the corrugated oil tank of different specifications. Loosening the nut 307 allows the slider 302 to slide along the slide groove 301 to adjust the spacing between the insert plates 207. After reaching the appropriate spacing, tighten the nut 307 and use the friction between the nut 307 and the surface of the vertical plate B204 to fix the position of the insert plate 207. It is flexible to use, easy to adjust, and suitable for the production and processing of corrugated oil tanks of different specifications.

[0019] The powder hopper 1 has a conveying pipe 202 installed at the discharge end, which is connected to the inside of the handle 201. One end of the conveying pipe 202 is connected to the pump assembly inside the powder hopper 1. A three-way valve 209 is installed at the connection between the conveying pipe 202 and the feed pipe 205. After being pressurized by the internal pump assembly, the powder is conveyed to the feed pipe 205 by the conveying pipe 202. The direction of powder discharge can be adjusted by the three-way valve 209 to meet different spraying requirements.

[0020] The upright plate B204 has a through groove 305 on one side of its surface, and the bolt 306 passes through the through groove 305. The nut 307 has a rubber ring 308 bonded to the side of its surface facing the upright plate B204. When the slider 302 moves, the bolt 306 moves along the through groove 305 without affecting the adjustment of the position of the insert plate 207. The rubber ring 308 structure can increase the friction between the nut 307 and the surface of the upright plate B204.

[0021] It should be noted that this utility model is a powder coating system for the outer wall of a transformer corrugated oil tank. During operation, the powder tank 1 has a handle 201 at its discharge end. The surface of the handle 201 has vertical plates A203 and B204. The powder is fed into either vertical plate A203 or B204 via a three-way valve 209. During ordinary spraying operations on the surface of the transformer corrugated oil tank, the powder is sprayed from the nozzle A206 on the surface of vertical plate A203. At this time, the spraying area is relatively large. Large size facilitates rapid spraying over large areas. When spraying the corrugated plates on the surface of the corrugated oil tank, adjust the three-way valve 209 to allow the powder to be sprayed out from one side of the vertical plate B204. After being transported into the interior of the vertical plate B204, the powder enters the insert plate 207 and is then sprayed out by the nozzle B208. Before operation, the position of the insert plate 207 can be adjusted so that it can be inserted precisely between adjacent corrugated plates. During the spraying operation, the insert plate 207 is inserted between the corrugated plates. At this time, the powder is sprayed out by the nozzle B208, which can be evenly sprayed to different positions on the surface of the corrugated plate, without being affected by the depth between the corrugated plates, thus improving the efficiency and uniformity of spraying on the outer wall of the corrugated oil tank. The slider 302 can move horizontally along the inside of the slide groove 301, driving the movement of the insert plate 207. The connecting pipes 303 are connected by the corrugated pipe 304, which not only ensures the normal transportation of powder, but also allows the slider 302 to move normally. During surface spraying, the position of the insert plate 207 and the spacing between the insert plates 207 can be adjusted according to the spacing of the corrugated plates on the surface of the corrugated oil tank of different specifications. Loosening the nut 307 allows the slider 302 to slide along the slide groove 301 to adjust the spacing between the insert plates 207. After reaching the appropriate spacing, tighten the nut 307 and use the friction between the nut 307 and the surface of the vertical plate B204 to fix the position of the insert plate 207. It is flexible in use, easy to adjust, and suitable for the production and processing of corrugated oil tanks of different specifications.
