Description

Technical Field

[0001] The utility model belongs to the technical field of fan production, and specifically relates to an anti-corrosion spraying device for a fan housing. Background Technique

[0002] In daily accidents such as fires, fire exhaust fans are usually used to exhaust smoke and ventilate the fire scene to ensure the safety of people's lives. Inside the fire exhaust fan, a fan is usually used as the power source for exhaust work. The fire fan can quickly discharge the smoke, toxic gases and heat in the room, increase the air circulation in the room, and provide a better rescue environment for firefighters.

[0003] When the fan inside the fire exhaust fan is in use, under the influence of some special environments, such as areas containing corrosive substances such as high-concentration chloride ions, ordinary fans may not be able to withstand long-term corrosion, resulting in a shortened service life. In order to extend the service life of the fan and improve its corrosion resistance, anti-corrosion spraying is required.

[0004] Currently, in the prior art, when anti-corrosion spraying is carried out on the housing of a fire fan, during the spraying process, the housing of the fire fan is usually placed on the surface of the workbench, and then sprayed by a spraying device. However, the existing spraying method can only spray on one end face of the housing of the fire fan, which will cause uneven spraying of the housing of the fire fan, and then cause waste of the spraying raw materials. Therefore, an anti-corrosion spraying device for a fan housing is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes an anti-corrosion spraying device for a fan housing.

When spraying the housing of the fire-fighting fan is required, the housing of the fire-fighting fan is placed on the top of the workbench 25, and then during the placement process, the clamping block 29 is pushed to slide to both sides by spreading, so that the clamping block 29 pushes the clamping plate 28 to compress the spring 27 to generate elastic force. When the housing of the fire-fighting fan is placed, the spring 27 generates elastic force to push the clamping block 29 to slide to the side end to clamp and fix the housing of the fire-fighting fan. Then, the double-shaft motor 24 is turned on to rotate, so that the double-shaft motor 24 drives the workbench 25 to rotate. Then, the anti-corrosion spraying device body 22 is turned on to spray on the surface of the housing of the fire-fighting fan to evenly spray on the surface of the housing of the fire-fighting fan and improve the spraying quality of the housing of the fire-fighting fan.

[0026] Further, as Figures 3 - 4 shown, a diversion cylinder is fixedly connected to the inner side wall of the spraying and sealing cylinder 1, and is located at the bottom of the workbench 25; during operation, by installing a diversion cylinder on the inner side wall of the spraying and sealing cylinder 1, the excess spraying stock solution generated during the spraying process is diverted and collected to the bottom, reducing the problem of waste.

When the rotating rod 41 rotates, it drives the guide rod 42 to rotate, so that the guide rod 42 drives the scraping plate 43 to rotate when it rotates, to scrape the stock solution adhering to the side wall of the diversion cylinder, reducing the problem of solidification and blockage caused by long-term accumulation.

[0028] Furthermore, as Figure 4 shown, a collection box 51 is fixedly connected inside the spraying and sealing cylinder 1 and is located at the bottom of the diversion cylinder; during operation, by installing the collection box 51 at the bottom of the spraying and sealing cylinder 1, the stock solution flowing down is collected, reducing the problem of waste.

[0029] Furthermore, as Figures 3 - 4 shown, a protective plate 32 is fixedly connected to the bottom of the workbench 25 and is in a horn shape; during operation, by installing the protective plate 32 at the bottom of the workbench 25, the dual-axis motor 24 is protected, reducing the problem of the spraying stock solution adhering to the surface of the dual-axis motor 24 and causing adhesion.

[0030] Furthermore, as Figures 1 - 2 shown, a circulating collection pipe 52 is installed at the end of the collection box 51, and the other end of the circulating collection pipe 52 is installed at the end of the anti-corrosion spraying device body 22; during operation, by installing the circulating collection pipe 52 between the collection box 51 and the anti-corrosion spraying device body 22, when the stock solution inside the collection box 51 is collected, by starting the circulating collection pipe 52, the stock solution inside the collection box 51 is diverted into the anti-corrosion spraying device body 22 for recycling, reducing the problem of waste caused by the spraying stock solution.

[0031] Furthermore, as Figure 1 shown, support legs 6 are fixedly connected to the bottom of the spraying and sealing cylinder 1 and are arranged in a circumferential array; during operation, by installing the support legs 6 at the bottom of the spraying and sealing cylinder 1, the spraying and sealing cylinder 1 is supported, reducing the problem of shaking during the spraying process.

[0032] Working principle: When it is necessary to spray the shell of the fire-fighting fan, place the shell of the fire-fighting fan on the top of the workbench 25. Then, during the placement process, slide the clamping blocks 29 to both sides by spreading them, so that the clamping blocks 29 push the clamping plates 28 to squeeze the springs 27 to generate elastic force. When the shell of the fire-fighting fan is placed completely, the springs 27 generate elastic force to push the clamping blocks 29 to slide towards the side ends to clamp and fix the shell of the fire-fighting fan. Then, turn on the double-shaft motor 24 to rotate, so that the double-shaft motor 24 drives the workbench 25 to rotate.
