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.
[0023] Please see Figures 1-3 This utility model provides a technical solution: a furnace nose filter for zinc ash recyclable filtration, including a furnace nose nozzle body 1, a suction pump 4 and a filter box 404. The bottom of the furnace nose nozzle body 1 is inserted into the plating tank 2. A pressure roller 201 is provided inside the plating tank 2, and a steel plate 3 is provided outside the pressure roller 201. The steel plate 3 is inserted through the furnace nose nozzle body 1.
[0024] A suction pump 4 is installed on one side of the furnace nose nozzle body 1. The furnace nose nozzle body 1 has a suction groove 402 and a gas delivery groove 406 inside. The bottom of the suction pump 4 is connected to the suction groove 402 via a suction pipe 401. The top of the suction pump 4 is connected to a filter box 404 via a gas guide pipe 403. The top of the filter box 404 is connected to a gas delivery pipe 405. The bottom of the gas delivery pipe 405 is connected to the gas delivery groove 406. Both the suction pipe 401 and the gas delivery pipe 405... The system is configured as a three-way pipe, with the larger openings of the suction pipe 401 and the gas supply pipe 405 connected to the suction pump 4 and the filter box 404, respectively. The gas supply trough 406 is located above the suction trough 402, and both the gas supply trough 406 and the suction trough 402 are located near the plating tank 2. There are two sets of the gas supply trough 406 and the suction trough 402, and their opening directions are opposite. One side of the filter box 404 is connected to the furnace nose nozzle body 1.
[0025] In specific implementation, to improve the utilization rate of the gas inside the furnace nose nozzle body 1, when the filter box 404 is used to filter the zinc ash in the gas inside the furnace nose nozzle body 1, the suction pump 4 installed on one side of the furnace nose nozzle body 1 is started. The suction pump 4 uses the suction pipe 401 and suction groove 402 to guide the gas containing zinc ash through the gas guide pipe 403 into the filter box 404 for filtration. The filtered gas is squeezed into the gas delivery pipe 405 and guided through the gas delivery pipe 405 to the gas delivery groove 406, and then the filtered gas is guided back into the furnace nose nozzle body 1 for recycling. This zinc ash recyclable furnace nose filter can reintroduce the zinc ash-removed gas into the furnace nose nozzle body 1 for use, effectively avoiding the suction pump 4 from sucking in a large amount of external gas, improving the recycling rate of the gas inside the furnace nose nozzle body 1, and keeping the inside of the furnace nose nozzle body 1 clean.
[0026] SeeFigure 3 and Figure 4 It is known that an air guide frame 5 is connected inside the filter box 404, and the bottom of the air guide frame 5 is connected to the air guide pipe 403. The filter box 404 is rotatably connected to one end of the rotating shaft 505 through a bearing seat. The other end of the rotating shaft 505 is connected to the output end of the stepper motor 504 through a coupling. One side of the stepper motor 504 is connected to the filter box 404. Filter plates 502 are equidistantly connected to the outside of the rotating shaft 505. The outside of the filter plates 502 is connected to the filter cage 501. Filter baffles 503 are equidistantly connected to the inside of the filter cage 501.
[0027] In specific implementation, to avoid clogging of the internal filter screen of the filter box 404 when filtering zinc ash, which would affect the filtration efficiency of subsequent gases, after the gas passes through the gas guide pipe 403 and the gas guide frame 5, the gas will come into contact with the filter cage 501 and be guided into the inside of the filter cage 501 through the filter baffle 503 at the filter cage 501. After being filtered by the filter plate 502, it is discharged. After the filter cage 501 has been used for a period of time, the stepper motor 504 on one side of the filter box 404 is started. The output end of the stepper motor 504 drives the rotating shaft 505, the filter plate 502 and the filter cage 501 to rotate through the coupling, thereby adjusting the filtration position and effectively avoiding clogging. The filter baffle 503 can prevent impurities intercepted by the filter cage 501 and the filter plate 502 from falling into the gas guide pipe 403 and affecting the use of the gas guide pipe 403. This zinc ash circulating filter furnace nose filter allows the filter cage 501, filter plate 502 and filter baffle 503 to rotate cyclically, effectively filtering the zinc ash in the gas.
[0028] In summary, when using this zinc ash recyclable furnace nose filter, after the steel plate 3 passes through the plating tank 2 and the pressure roller 201 in sequence and enters the furnace nose nozzle body 1, the suction pump 4 is started. The suction pump 4 guides the gas containing zinc ash through the suction pipe 401 and the suction trough 402 and introduces it into the filter box 404 through the gas guide pipe 403 for filtration. The filtered gas is guided to the gas delivery trough 406 through the gas delivery pipe 405, and then the filtered gas is guided back into the furnace nose nozzle body 1 for recycling.
