Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology, and in particular to an energy-saving and environmentally friendly high-speed pulse flame galvanizing furnace. Background Technology

[0002] A search revealed that Chinese patent CN216765023U discloses a hot-dip galvanizing furnace for hot-dip galvanizing processing. The furnace includes a zinc pot for holding molten zinc, a combustion port at the bottom of the zinc pot for heating, and a boiler body. The zinc pot is placed inside the boiler body, and a support roller is fixedly connected to the inner bottom wall of the boiler body. The upper end of the support roller is rotatably connected to the zinc pot. A stirring rod is installed inside the zinc pot, and a stirring assembly is connected to the zinc pot to stir the molten zinc by driving the zinc pot to rotate relative to the stirring rod. When heating the molten zinc in the zinc pot is required, the stirring assembly drives the zinc pot to rotate relative to the stirring rod. This rotation of the zinc pot causes the molten zinc inside to rotate. Simultaneously, the combustion port heats the zinc pot, and the stirring rod's stirring of the molten zinc facilitates more uniform heating and ensures a more even temperature distribution within the zinc pot.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were found: When this device is in use, it cannot filter the generated oxides simultaneously, which will cause the workpiece to directly adsorb these impurities during immersion plating, forming large-area slag spots, pits, unevenness and other defects. At the same time, manual cleaning of the inner surface of the tank is required, and the manual scraping of the slag layer is labor-intensive and has high labor costs. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly high-speed pulse flame galvanizing furnace, which can solve the problem that the device cannot filter the generated oxides simultaneously during use, which causes the workpiece to directly absorb these impurities during immersion galvanizing, resulting in large-area slag spots, pits, unevenness and other defects. At the same time, it requires manual cleaning of the inner surface of the tank, and the manual scraping of the slag layer is labor-intensive and has high labor costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an energy-saving and environmentally friendly high-speed pulse flame galvanizing furnace, comprising a heat-insulating tank and a galvanizing pot, wherein a support plate is fixedly connected to the outer surface of the heat-insulating tank, and further comprising:

[0006] The filter assembly is located inside the galvanizing pot;

[0007] The drive assembly is located on the outer surface of the insulated tank;

[0008] The rotating assembly is located on the surface of the galvanized pot.

[0009] In a preferred embodiment, a heating component is provided on the lower inner side of the insulated tank, the heating component comprising:

[0010] The furnace cavity is threadedly connected to the lower inner surface of the insulated tank.

[0011] The gas supply pipe is fixedly connected to the lower surface of the furnace cavity;

[0012] Multiple combustion nozzles are evenly and fixedly connected to the upper surface of the furnace cavity.

[0013] In a preferred embodiment, the filtering component includes:

[0014] The filter tank is located inside the galvanizing pot;

[0015] Multiple support columns are fixedly connected to the upper surface of the filter tank;

[0016] The filter box is fixedly connected to the outer surface of the filter tank.

[0017] A flow guide plate is fixed to the outer surface of the support column, and the outlet of the flow guide plate is located above the filter box;

[0018] A fixing plate is fixedly connected to the lower outer surface of the filter tank, and a cross groove is provided on the lower surface of the fixing plate.

[0019] In a preferred embodiment, the driving component includes:

[0020] The motor is movably connected to the upper surface of the support plate;

[0021] The rotating shaft is fixedly connected to the motor output end;

[0022] Gear 1 is movably connected to the outer surface of the shaft.

[0023] In a preferred embodiment, a support leg is fixedly connected to the outer surface of the heat preservation tank, and a rubber base is provided on the lower surface of the support leg.

[0024] In a preferred embodiment, a limiting device is fixedly connected to the outer surface of the galvanizing pot, and a turntable is rotatably connected to the inner surface of the galvanizing pot, with a cross groove provided on the upper surface of the turntable.

[0025] In a preferred embodiment, the rotating assembly includes:

[0026] Gear 2 is movably connected to the outer surface of the galvanizing pot, and gear 2 meshes with gear 1;

[0027] A side scraper is provided on the inner surface of the galvanizing pot, and the side scraper is slidably connected to the inner surface of the galvanizing pot;

[0028] Limiting device two is movably connected to the outer surface of the galvanizing pot. The limiting device two is slidably connected to the upper surface of the galvanizing pot. A side scraper is fixedly connected to the lower surface of the limiting device two. A gear two is fixedly connected to the lower surface of the limiting device two.

[0029] A bottom scraper is disposed on the inner surface of the galvanizing pot. The bottom scraper is slidably connected to the inner surface of the galvanizing pot. The lower outer surface of the bottom scraper is movably connected to the cross groove of the turntable, and the upper outer surface of the bottom scraper is movably connected to the cross groove of the fixed plate.

[0030] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, the rotating component is placed inside the galvanizing pot. The limiting device two allows the rotating component to be movably connected to the galvanizing pot, while simultaneously ensuring that gear two meshes with gear one, guaranteeing that the rotating component can only move along a preset path and achieving synchronous rotation. Simultaneously, the bottom scraper is positioned in the cross groove of the turntable. The filter tank is placed inside the galvanizing pot and connected to the rotating component via the cross groove on the fixed plate, thereby maximizing the protection of the filter tank during dynamic thermal deformation. To maintain the system's operational stability, after installation, zinc powder is placed in the galvanizing pot, and the pot is heated to melt the zinc powder. The molten zinc is brought to a height below the guide plate. The motor is then started, driving the gears to rotate, which in turn rotates the rotating components and the filter tank, agitating the molten zinc to ensure uniform temperature and composition, reduce coating thickness fluctuations, and allow the molten zinc to cover the workpiece surface more quickly and evenly. As the side and bottom scrapers rotate, they simultaneously scrape away the scale layer formed on the inner surface of the galvanizing pot, thus cleaning the pot and extending its service life.

[0031] The galvanized parts are placed in the zinc bath in the filter tank for galvanizing. During galvanizing, an oxidation reaction occurs, and the surface of the zinc bath is the area where oxides are most concentrated. The rotation of the guide plate drives the surface liquid to flow along the guide plate into the filter box. After filtration, it falls back into the galvanizing pot, reducing the probability of defective products caused by oxide contamination of the coating during the galvanizing process.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Example 1

[0043] Please see Figures 1 to 7 This utility model provides a technical solution: an energy-saving and environmentally friendly high-speed pulse flame galvanizing furnace, including a heat preservation tank 1, a galvanizing pot 3, a filter assembly, a drive assembly, and a rotating assembly. The drive assembly is used to drive the rotating assembly and the filter assembly to rotate relative to each other. The heat preservation tank 1 is used to keep the galvanizing pot 3 warm and prevent heat loss.

[0044] The drive assembly includes and the rotation assembly includes:

[0045] Motor 4 is movably connected to the upper surface of support plate 102. A rotating shaft 404 is fixedly connected to the output end of motor 4. Gear 401 is fixedly connected to the outer surface of rotating shaft 404. Motor 4 drives rotating shaft 404 to rotate, synchronously driving gear 401 to rotate. Gear 401 and gear 402 are meshed, synchronously driving gear 402 to rotate. Limiting device 405 is fixedly connected to the outer surface of gear 402. Limiting device 405 is slidably connected to the upper surface of galvanizing pot 3. A side scraper 403 is fixedly connected to the inner surface of limiting device 405. Gear 402 drives the side scraper 403. The 03 and bottom scraper 406 rotate synchronously. The upper surface of the turntable 302 is provided with a cross groove, and the lower surface of the fixed plate 504 is provided with a cross groove. The bottom scraper 406 is fixed in the cross groove of the turntable 302 and the cross groove of the fixed plate 504 respectively, ensuring that the cross groove can provide high-precision positioning and reliable anti-displacement fixation during rotation, while facilitating disassembly. The side scraper 403 is slidably connected to the inner surface of the galvanizing pot 3, and the bottom scraper 406 is slidably connected to the inner surface of the galvanizing pot 3. When the side scraper 403 and the bottom scraper 406 rotate, they will simultaneously scrape off the scale layer generated on the inner surface of the galvanizing pot 3.

[0046] The filtering components include:

[0047] The filter tank 5 is located inside the galvanizing pot 3. A fixed plate is fixed on the lower surface of the filter tank 5. The filter tank 5 can be rotated synchronously by rotating the fixed plate 504. Multiple support columns 503 are set on the upper surface of the filter tank 5 and connected to the diversion plate 502 to ensure the stability of the diversion plate 502. The synchronous filter box 501 is set on the outer surface of the filter tank 5 and located below the diversion plate 502 to ensure that the liquid passing through the diversion plate 502 can fall into the filter box 501 for filtration.

[0048] It should be noted that there is a certain distance between the side scraper 403 and the diversion plate 502 and the filter box 501 to ensure that they will not collide with each other.

[0049] In the specific implementation process: the rotating component is placed inside the galvanizing pot 3, and the rotating component is movably connected to the galvanizing pot 3 by the limiting device 2 405. At the same time, it is ensured that gear 2 402 and gear 1 401 are meshed, ensuring that the rotating component can only move along the preset path, thus ensuring synchronous rotation. Simultaneously, the bottom scraper 406 is positioned in the cross groove of the turntable 302. The filter tank 5 is placed inside the galvanizing pot 3 and connected to the rotating component through the cross groove on the fixed plate 504. This maximizes the stability of the system during dynamic thermal deformation. After completion, zinc powder is placed in the galvanizing pot 3, and the galvanizing pot 3 is heated to melt the zinc powder. The zinc liquid level is then positioned below the guide plate 502. The motor 4 is started, driving the gear 401 to rotate, which in turn drives the rotating assembly and the filter tank 5 to rotate, stirring the zinc liquid to ensure uniform temperature and composition, reduce coating thickness fluctuations, and allow the zinc liquid to cover the workpiece surface more quickly and evenly. When the side scraper 403 and the bottom scraper 406 rotate, they simultaneously scrape away the scale layer generated on the inner surface of the galvanizing pot 3, thereby cleaning the galvanizing pot 3 and extending its service life.

[0050] The galvanized parts are placed in the zinc bath in the filter tank 5 for galvanizing. During galvanizing, an oxidation reaction occurs, and the surface of the zinc bath is the area where oxides are most concentrated. The rotation of the guide plate 502 drives the surface liquid to flow along the guide plate 502 into the filter box 501. After filtration, it falls back into the galvanizing pot 3, which reduces the probability of defective products being produced due to oxide contamination of the coating during the galvanizing process.

[0051] Example 2

[0052] It should be noted that, based on Example 1, such as Figure 2 As shown, the heating assembly includes:

[0053] The furnace chamber 2 is threaded to the lower inner surface of the insulation tank 1, ensuring stability and sealing. A gas supply pipe 202 is fixedly connected to the lower surface of the furnace chamber 2 to ensure the supply of gas. Multiple combustion nozzles 201 are fixedly connected to the upper surface of the furnace chamber 2. The multiple combustion nozzles 201 are evenly distributed on the surface of the furnace chamber 2, and flames are sprayed out through the combustion nozzles 201 to heat the galvanizing pot 3.

[0054] In the specific implementation process: the furnace cavity 2 is threadedly connected to the inner surface of the insulation tank 1 to ensure stability and sealing, while facilitating the maintenance and upkeep of the heating components. After the heating components are installed, gas is supplied to the furnace cavity 2 through the gas supply pipe 202 from the outside, and the flame is ignited by multiple combustion nozzles 201 to heat the galvanizing pot 3.

[0055] Working principle:

[0056] The rotating assembly is placed inside the galvanizing pot 3. The limiting device 405 allows the rotating assembly to be movably connected to the galvanizing pot 3, while simultaneously ensuring that gear 402 meshes with gear 401. This ensures the rotating assembly can only move along a preset path, guaranteeing synchronous rotation. Simultaneously, the bottom scraper 406 is positioned in the cross groove of the turntable 302. The filter tank 5 is then placed inside the galvanizing pot 3 and connected to the rotating assembly via the cross groove on the fixed plate 504. This maximizes the system's operational stability during dynamic thermal deformation. After installation... Zinc powder is placed in the galvanizing pot 3 and heated to melt the zinc powder. The molten zinc is brought to the lower end of the guide plate 502. The motor 4 is started, which drives the gear 401 to rotate. This simultaneously drives the rotating component and the filter tank 5 to rotate, stirring the molten zinc to ensure uniform temperature and composition, reduce coating thickness fluctuations, and allow the molten zinc to cover the workpiece surface more quickly and evenly. When the side scraper 403 and the bottom scraper 406 rotate, they simultaneously scrape off the scale layer generated on the inner surface of the galvanizing pot 3, thereby cleaning the galvanizing pot 3 and extending its service life.

[0057] The galvanized parts are placed in the zinc bath in the filter tank 5 for galvanizing. During galvanizing, an oxidation reaction occurs, and the surface of the zinc bath is the area where oxides are most concentrated. The rotation of the guide plate 502 drives the surface liquid to flow along the guide plate 502 into the filter box 501. After filtration, it falls back into the galvanizing pot 3, which reduces the probability of defective products being produced due to oxide contamination of the coating during the galvanizing process.

[0058] The furnace chamber 2 is threaded onto the inner surface of the insulation tank 1, ensuring stability and sealing, while also facilitating the maintenance and upkeep of the heating components. After the heating components are installed, gas is supplied to the furnace chamber 2 through the gas supply pipe 202 from the outside, and the flame is ignited by multiple combustion nozzles 201 to heat the galvanizing pot 3.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
