Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to zinc ash filters. Background Technology

[0002] To date, hot-dip galvanizing remains the most widely used and effective method for steel corrosion protection. Since its introduction, hot-dip galvanized steel has been widely used in various industries, including construction and home appliances. Due to the expanding applications and increasing demands on the formability and various properties of steel sheets, aluminized zinc-coated steel sheets have emerged, offering superior performance in some aspects compared to hot-dip galvanized steel sheets. Aluminized zinc-coated steel sheets are made from cold-rolled hard steel sheets of various strengths and thicknesses, coated with an AL-Zn alloy using a hot-dip galvanizing process. The aluminum-zinc alloy coating on the steel sheet surface consists of 55% aluminum, 43.4% zinc, and 1.6% silicon, solidified at 600°C. Its entire structure is a dense quaternary crystal composed of aluminum, iron, silicon, and zinc. During the production of aluminum zinc plating, the temperature of the zinc liquid is close to 600℃. At this temperature, the zinc liquid evaporates and is suspended in the protective atmosphere inside the furnace nose. When it cools down, it will condense into zinc ash. Some of the zinc ash falls on the surface of the zinc liquid, causing zinc ash defects. In severe cases, it will cause incomplete plating. Therefore, in the production process, an external zinc ash filter is usually connected to filter the zinc ash.

[0003] Existing zinc ash filter cartridges typically employ a multi-stage filtration method. The zinc ash filter first filters the zinc ash through a filter cotton cartridge. However, during use, the zinc ash is difficult to make even contact with the outer wall of the filter cotton cartridge, resulting in some filter cotton still being able to perform filtration when the filter cotton cartridge needs to be replaced.

An insert rod 24 is slidably inserted into the through hole 20. One end of the insert rod 24 is inserted into one of the positioning grooves 25. The other end of the insert rod 24 is fixedly connected to a pull block 19. Two sliding grooves 22 are symmetrically provided on the inner wall of the through hole 20.

[0027] The barrier includes multiple equidistant annular arrays of partitions 11 fixed to the outside of the filter cylinder 7. An arc-shaped filter plate 8 is slidably connected between two adjacent partitions 11. The inner wall of the filter cylinder 1 is provided with multiple equidistant annular arrays of slots 16. A sealing plate 9 is respectively engaged in each slot 16. A connecting groove 18 is provided at one end of one side of the partition 11. A connecting block 17 is hinged in the connecting groove 18 and fixedly connected to the sealing plate 9.

The top wall of the sealing cover 3 is rotatably connected to a ring. The ring abuts against the top surface of the partition 11.

[0028] By rotating the connecting filter cylinder 7 inside the filter cylinder 1, and fixing multiple barrier components to the outside of the filter cylinder 7, and setting a filter cotton 6 between each of two adjacent barrier components, the contact area between the filter cotton 6 and the zinc ash is increased, making the contact between the zinc ash and the filter cotton 6 more uniform. A conversion component and a positioning component are set on the bottom surface of the filter cylinder 1 to facilitate the switching of multiple filter cottons 6, ensuring the filtering effect of the filter cotton 6 on the zinc ash, and also reducing the number of times the filter cotton 6 needs to be replaced.

[0029] Working principle: During use, an induced draft fan is connected to the end of the exhaust pipe. Gas containing zinc ash enters the filter cartridge 1 through the intake pipe 2 via the induced draft fan. The filter cotton 6 inside the filter cartridge 1 filters the zinc ash in the gas. The filtered gas enters the filter cylinder 7, while the zinc ash remains on the outside of the filter cotton 6. The filtered gas is discharged through the exhaust pipe on the top surface of the sealing cover 3. When it is necessary to change the filter cotton 6, pull the pull block 19. The pull block 19 pulls the insertion rod 24 out of the positioning groove 25, and at the same time, the first spring 21 is compressed. Then, by rotating the rotating block 4... The rotating block 4 drives the filter cylinder 7 to rotate via the rotating shaft. The filter cylinder 7 drives the filter cotton 6 to rotate, and the partition plate 11 rotates synchronously with the filter cylinder 7. When the partition plate 11 rotates, the sealing plate 9 flips through the connecting plate hinged in the connecting groove 18, and the torsion spring retracts, causing the sealing plate 9 to leave the slot 16. This allows the new filter cotton 6 to move to one side of the air intake pipe 2. At this time, the sealing plate 9 will rotate into the corresponding slot 16, and the torsion spring will return to its original position. The positioning groove 25 on the rotating block 4, which is aligned with the new filter cotton 6, rotates to one side of the insertion rod 24, and then the pull block is released. 19. The first spring 21, which is in a compressed state, resets. When the spring resets, it pushes the insertion rod 24 into the positioning groove 25 to limit and fix the rotating block 4. When all the filter cotton 6 has been used, the water inlet is stopped, the sealing cover 3 is opened, and the second spring, which is in a compressed state, resets. When the second spring resets, it pushes the support block to rise, and the support block drives the guide block 12 to rise, so that the arc-shaped filter plate 8 and the filter cotton 6 move upward, so that the top surface of the arc-shaped filter plate 8 is higher than the top surface of the filter cylinder 7. Then the arc-shaped filter plate 8 and the filter cotton 6 are taken out from the filter cylinder 1. 6. Remove the arc-shaped filter plate 8 and clean it. After cleaning, install the new filter cotton 6 back onto the outside of the arc-shaped filter plate 8 using the dovetail groove 14 and dovetail block 15. Then, install the clean arc-shaped filter plate 8 with the new filter cotton 6 back into the filter cylinder 1. During installation, snap the guide block 12 into the guide groove 13. Then, install the sealing cover 3 back onto the top surface of the filter cylinder 1. When the sealing cover 3 descends, it squeezes the arc-shaped filter plate 8 down, making the top surface of the arc-shaped filter plate 8 flush with the top surface of the filter cylinder 7. At the same time, the second spring is compressed, thus completing the replacement of the filter cotton 6.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
