Description

Technical Field

[0001] The utility model relates to the technical field of smoke filtering treatment of aluminum smelting furnaces, in particular to a smoke filtering device of a removable filter assembly for secondary aluminum ash treatment regeneration aluminum smelting furnace. Background Art

[0002] In the production process of secondary aluminum smelting furnace, the melting of aluminum metal is a crucial step. However, this process is often accompanied by the generation of a large amount of smoke. These fumes not only contain impurities and particulate matter released during the melting of aluminum metal, but may also contain some harmful substances, such as sulfur dioxide, nitrogen oxides, etc. The release of these harmful substances will not only pollute the environment and affect the air quality, but may also pose a threat to the health of workers at the production site.

[0003] Chinese patent publication number CN215893276U discloses a smoke filtering device for a regenerative aluminum smelting furnace. A water pump delivers water to a nozzle to spray the smoke, so that impurities in the smoke are adsorbed with water vapor and increase their own weight to slide downward and adhere to the second filter plate, the folding plate and the first filter plate, thereby preliminarily filtering the smoke impurities. Then the gas is guided from the connecting pipe to the water source. Under the further adsorption of the water source, the impurities in the gas are further filtered. Finally, the gas moves upward and passes through the demister and two layers of activated carbon layers in sequence, which can filter the water vapor in the gas and adsorb the harmful substances in the gas, thereby filtering the smoke to avoid affecting the environment and personnel health.

[0004] However, in actual use, the above structure will gradually reduce its filtering effect in the long-term operation process because the filter plate cannot be cleaned and replaced in a timely and effective manner. This reduction is not only reflected in the decrease of filtering efficiency, but also in the loss of filtering precision, and even the clogging and damage of the filter plate surface. These unfavorable factors will eventually lead to a significant reduction in the smoke filtering effect of the equipment. Utility Model Content

[0031] After the dust enters through the air inlet 11, the submersible water pump in the water tank 12 is started to spray water into the body 1 through the connecting pipe 13 and the nozzle 14 to carry out dust reduction treatment. Subsequently, the multi-link scraper 31, driven by the driving mechanism 4, reciprocates horizontally and linearly to scrape and clean the upper and lower surfaces of the first filter plate 2 to avoid the first filter plate 2 from reducing the dust purification effect due to long-term use, and to avoid the first filter plate 2 from reducing the purification effect due to long-term use.

[0032] See also Figure 6 and Figure 7 As shown, the driving mechanism 4 includes a half-sector gear 41 and a sliding block 42; the half-sector gear 41 is rotatably mounted on the body 1; the sliding block 42 is slidably mounted on the body 1 and meshes with the half-sector gear 41, and a rotation driver 45 is provided on the body 1, and the output end of the rotation driver 45 is connected to a transmission rod 46 through a coupling, the outside of the transmission rod 46 is coaxially fixed with the half-sector gear 41, and the other end of the transmission rod 46 is fixed to the end of the body 1 through a bearing, and a plurality of racks 47 meshing with the half-sector gear 41 are provided on the sliding block 42, and a pair of limiting blocks 48 respectively close to the ends of the sliding block 42 are provided on the body 1, and travel blocks 49 are respectively installed at both ends of the sliding block 42, and an opening for the travel block 49 to pass through is opened on the limiting block 48.

[0033] When the half-sector gear 41 rotates, the sliding block 42 slidably arranged on the body 1 can slide back and forth in a horizontal straight line. As the half-sector gear 41 rotates, the sliding block 42 slides back and forth in a horizontal straight line on the body 1. A plurality of racks 47 are arranged on the upper and lower sides of the sliding block 42. The rotation of the half-sector gear 41 drives the sliding block 42 and the travel block 49 meshing therewith to slide smoothly in a horizontal straight line along the avoidance groove of the limiting block 48. The travel block 49 ensures the stability of the sliding block 42 during the sliding process.

[0034] See also Figure 1 and Figure 3 As shown, the driving mechanism 4 also includes a limiting groove 43 and a connecting block 44; the limiting groove 43 is opened on the body 1 and has a plurality of connecting blocks 44; the connecting block 44 is slidably set in the limiting groove 43 and is fixed to the end of the sliding block 42, and a positioning rod 491 is set in the limiting groove 43, which passes through the connecting block 44 and is fixed to the two ends of the limiting groove 43. A mounting block 492 for inserting and installing the multi-link scraper 31 is opened on the connecting block 44, and a threaded mounting groove for threaded engagement with a locking bolt is opened on the mounting block 492, and the multi-link scraper 31 is connected to the mounting block 492 by a locking bolt.

[0035] When the sliding block 42 slides under the drive of the driving mechanism 4, the connecting block 44 slides in the limiting groove 43, thereby driving the multi-link scraper 31 to scrape and clean the upper and lower surfaces of the first filter plate 2. If the multi-link scraper 31 needs to be disassembled and cleaned, just turn the locking bolt on the mounting block 492 to easily remove the multi-link scraper 31 from the mounting block 492. When installing, first insert the multi-link scraper 31 into the mounting groove of the mounting block 492, and then turn the locking bolt in the opposite direction to firmly install the multi-link scraper 31 on the mounting block 492.

[0036] See also Figure 6 and Fig.10 As shown, the mounting mechanism 5 includes a first limiting frame 51 and a clamping rod 52; the first limiting frame 51 is arranged in the machine body 1 and is located below the multi-link scraper 31; the clamping rod 52 is slidably arranged on the machine body 1 and slidably cooperates with the first limiting frame 51, and a sliding cavity for sliding the clamping rod 52 is provided on the machine body 1, and a return spring 53 is provided on the outside of the clamping rod 52, and both ends of the return spring 53 are respectively fixed to the end of the clamping rod 52 and the first limiting frame 51, and a mounting hole for inserting the clamping rod 52 is provided on the first filter plate 2.

[0037] When the first filter plate 2 needs to be removed, the user needs to first pull the clamping rod 52 away from the machine body 1, so that the return spring 53 is compressed under the action of the first limiting frame 51. As the clamping rod 52 moves, the other end thereof will gradually detach from the mounting holes opened on both sides of the first filter plate 2. Once the clamping rod 52 is completely detached from the mounting holes, the user can easily pull the first filter plate 2 out from the outside of the first limiting frame 51, thereby achieving quick removal.

[0038] See also Fig. 9 and Fig.12 As shown, the recovery mechanism 6 includes a recovery box 61 and a second filter plate 62; the recovery box 61 is arranged in the body 1 and is located below the first filter plate 2, the second filter plate 62 is movably arranged above the recovery box 61 and close to one side of the multi-link scraper 31, and a frame block 631 for limiting the installation of the second filter plate 62 is provided in the recovery box 61, and a plurality of positioning columns 64 are provided on the recovery box 61, and a toggle block 65 is rotatably installed on each positioning column 64, and the toggle block 65 is used to install the second filter plate 62 on the frame block 631, and an adsorption sponge can also be placed in the recovery box 61, and the adsorption sponge is used to further adsorb and filter dust in the water to ensure the water quality in the recovery box 61.

[0039] During operation, when the multi-link scraper 31 slides on a horizontal straight line, it can not only scrape off the dust on the first filter plate 2, but also simultaneously scrape off the dust on the second filter plate 62. After the sprayed water absorbs the dust, the water will be filtered in turn through the first filter plate 2 and the second filter plate 62. The water that absorbs the dust after double filtration will eventually flow into the recovery box 61. At this time, the adsorption sponge in the recovery box 61 will perform secondary filtration on the water to further ensure the purity of the water quality.
