An automatic large zinc pot slag scooping machine

Abstract

The present invention relates to the field of metal smelting and processing, and in particular to an automated large-scale zinc pot slag skimmer, comprising an outer filter basin, an inner filter basin, and a filter plate. The automated large-scale zinc pot slag skimmer of the present invention primarily comprises an outer filter basin and an inner filter basin with mutually telescopic structures, and a detachable filter plate forming a loading container. A transverse scraper is provided at the bottom of the filter plate, which is in close contact with the bottom of the zinc pot to scrape off the zinc slag. During rotation, the transverse scraper cooperates with a stirring blade to stir up a small vortex in the zinc liquid, thereby continuously collecting the scraped zinc slag into the loading container. Furthermore, a vertical straight scraper is provided on the transverse scraper to scrape off the zinc slag remaining in the corners of the bottom of the zinc pot, thereby improving the scraping effect of the residual zinc slag at the bottom of the zinc pot. This overcomes the technical problem of existing large-scale zinc pot slag skimmers having a small contact area with the bottom of the zinc pot and being unable to completely remove the zinc slag attached to the bottom of the zinc pot.

Description

Technical Field

[0001] The present invention relates to the field of metal smelting and processing, in particular to an automatic large-scale zinc pot slag scooping machine. Background Art

[0002] A zinc pot slag remover is a device used to clean the zinc slag at the bottom of the zinc pot. Regular cleaning of the zinc slag at the bottom of the zinc pot is an indispensable part of hot-dip galvanizing production. It adopts automatic or semi-automatic operation and separates the zinc slag at the bottom of the zinc pot from the liquid zinc through a mechanical device to maintain the cleanliness of the zinc liquid in the zinc pot and production efficiency. Existing large-scale zinc pot slag removers usually use two automatically opening and closing mechanical claws to salvage the zinc slag in the zinc pot. Since the contact area between the mechanical claws and the bottom of the zinc pot is small, this treatment method cannot completely salvage the zinc slag attached to the bottom of the zinc pot, resulting in a large amount of zinc slag residue at the bottom of the zinc pot. Uncleaned zinc slag will increase the impurity content in the zinc liquid, making it more difficult to purify the zinc liquid, and thus affecting the recycling efficiency of the zinc liquid. The accumulation of zinc slag may cause local overheating of the zinc pot, increasing the risk of fire and explosion. Summary of the Invention

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] An automatic large zinc pot slag scooping machine, such as Figure 1-Figure 5As shown, it includes a mounting plate 11, a main guide rod 12, a main slide 13, a first elevator 14, a secondary guide rod 15, a secondary slide 16, a second elevator 17, a fixing rod 18, an outer filter basin 21, an inner filter basin 22, a ring frame 23, a filter plate 24, a transverse scraper 25 and a slow rotating stirring mechanism; the mounting plate 11 is fixed with the main guide rod 12; the main slide 13 is slidably connected to the main guide rod 12; the first elevator 14 is installed on the mounting plate 11; the lifting component of the first elevator 14 is fixed to the main slide 13; the main slide 13 is fixed with the secondary guide rod 15; the secondary slide 16 is slidably connected to the secondary guide rod 15; the main slide 13 is installed with a driving mechanism for the secondary slide 1 Second elevator 17; the lifting component of second elevator 17 is fixed to auxiliary slide 16; a fixing rod 18 is fixed to auxiliary slide 16; an outer filter basin 21 is fixed to auxiliary guide rod 15; an inner filter basin 22 is slidably connected to the inner portion of outer filter basin 21; a slow-rotating stirring mechanism is connected to auxiliary slide 16; a filter plate 24 is connected to the slow-rotating stirring mechanism; the filter plate 24 has a conical surface that bulges toward the center; an annular frame 23 is rotatably connected to the outer edge of the filter plate 24; the fixing rod 18 is fixed to the annular frame 23; the annular frame 23 is closely attached to the bottom of the inner filter basin 22; the outer filter basin 21, the inner filter basin 22, and the filter plate 24 together form a loading container; three horizontal scrapers 25 are fixed to the bottom of the filter plate 24.

[0027] like Figure 3 As shown, the slow rotating stirring mechanism of this embodiment is composed of a slow motor 31, a spline shaft 32, a sleeve shaft 33 and a stirring blade 34; the slow motor 31 is installed on the sub-slide 16; the spline shaft 32 is rotatably connected to the sub-slide 16; the output shaft of the slow motor 31 is fixedly connected to the spline shaft 32; the sleeve shaft 33 is fixedly connected to the filter plate 24; the sleeve shaft 33 is movably connected to the spline shaft 32; and the stirring blade 34 is fixedly connected to the outer surface of the sleeve shaft 33.

[0028] The large-scale automated zinc pot slag scooping machine of this embodiment is installed on the gantry crane through the mounting plate 11 , and the large-scale automated zinc pot slag scooping machine of this embodiment is sequentially controlled by the gantry crane to move to various areas of the zinc pot to perform zinc slag scooping work in sequence.

[0029] During the zinc slag salvage operation, the first elevator 14 first drives the main slide 13 to slide downward along the main guide rod 12, allowing the auxiliary guide rod 15 driven by the main slide 13 and the loading container consisting of the outer filter basin 21, the inner filter basin 22 and the filter plate 24 connected to the fixed rod 18 to be immersed downward in the zinc liquid in the zinc pot until the transverse scraper 25 under the filter plate 24 is in close contact with the bottom of the zinc pot. At this time, the outer filter basin 21, the inner filter basin 22 and the filter plate 24 are all completely immersed below the zinc liquid level in the zinc pot. Then the slow motor 31 drives the spline shaft 32 and the sleeve shaft 33 to move downward. The sleeve shaft 33 rotates, driving the filter plate 24, the transverse scraper 25 and the stirring blade 34 to rotate slowly. The rotating transverse scraper 25 is close to the bottom of the zinc pot and continuously scrapes the remaining zinc slag upwards. At the same time, the rotating transverse scraper 25 and the stirring blade 34 stir together in the zinc liquid to form a small vortex. The scraped zinc slag will be collected into the loading container along with the vortex. At this time, the inner filter basin 22 is in a state of being retracted into the outer filter basin 21. Therefore, the top height of the entire loading container is close to the bottom of the zinc pot, so that the zinc slag can be collected into the loading container more smoothly.

[0030] Afterwards, the gantry crane controls the automatic large-scale zinc pot slag scooping machine of this embodiment to move to the adjacent area in the zinc pot. At this time, the loading container remains immersed in the zinc liquid, and according to the above steps, the rotating transverse scraper 25 scrapes the residual zinc slag in the new area at the bottom of the zinc pot upward, and cooperates with the stirring blade 34 to collect the scraped zinc slag into the loading container, thereby continuously scraping and collecting the residual zinc slag in various areas at the bottom of the zinc pot. As the zinc slag collected in the loading container increases, the first elevator 14 drives the main slide 13 to slide slowly upward along the main guide rod 12, allowing the main slide 13 to drive the outer filter basin 21 connected to the secondary guide rod 15 to slowly rise upward. At the same time, the second elevator 17 pushes the secondary slide 16 to move downward along the secondary guide rod 15, so that the filter plate 24 and the annular frame 23 do not move upward with the outer filter basin 21, thereby ensuring that the transverse scraper 25 below the filter plate 24 can remain close to the bottom of the zinc pot to continuously scrape the residual zinc slag, and the inner filter basin 22 will also expand downward along the outer filter basin 21 under the action of gravity. Figure 6 As shown, the loading container is slowly lifted up and unfolded so that more zinc slag can be loaded into the loading container.

[0031] After a batch of zinc slag collection is completed, the first elevator 14 drives the main slide 13 to move upward along the main guide rod 12. At the same time, the auxiliary guide rod 15 and the fixed rod 18 driven by the main slide 13 are connected to the loading container to move upward away from the zinc liquid and hover above the zinc pot, allowing the zinc liquid carried up in the loading container to be completely filtered downward along the filter holes in the filter plate 24 and returned to the zinc pot. Then, the gantry crane controls the automatic large-scale zinc pot slag scooping machine of this embodiment to drive the loading container to move above the recovery point, and then the second elevator 17 pushes the auxiliary slide 16 along the auxiliary guide rod 15 and the fixed rod 18 to move upward away from the zinc liquid and hover above the zinc pot. The rod 15 moves downward, and the auxiliary slide 16 drives the filter plate 24 and the annular frame 23 connected to the fixed rod 18 downward to leave the inner filter basin 22. After the inner filter basin 22 moves downward to below the outer filter basin 21, the inner filter basin 22 will be restricted by the range of motion of the slide connected to the outer filter basin 21 and will no longer fall downward. Therefore, a large gap will exist between the filter plate 24 and the inner filter basin 22. At this time, the zinc slag collected in the loading container will slide outward from the gap along the inclined outer surface of the filter plate 24 to the recovery area, completing the salvage and recovery of this batch of zinc slag.

[0032] like Figure 3 As shown, each transverse scraper 25 of this embodiment is fixedly connected to a vertical oblique scraper 26; all vertical oblique scrapers 26 are in close contact with the outer surface of the outer filter basin 21; when the transverse scrapers 25 are in close contact with the bottom of the zinc pot and continuously scrape away the residual zinc slag, the transverse scrapers 25 drive the vertical oblique scrapers 26 to rotate together, and the rotating vertical oblique scrapers 26 continuously push the scraped zinc slag upward, allowing the zinc slag to enter the loading container more smoothly. The vertical oblique scrapers 26 also rotate in close contact with the outer surface of the outer filter basin 21, and the zinc slag that rises upward and adheres to the outer surface of the outer filter basin 21 is scraped off by the vertical oblique scrapers 26, thereby preventing a large amount of zinc slag from remaining on the outer surface of the outer filter basin 21.

[0033] like Figure 5 As shown, each horizontal scraper 25 of this embodiment is fixed with a slide bar 27; each slide bar 27 is fixed with a vertical straight scraper 28, and the vertical straight scraper 28 uses an elastic high-temperature resistant spring material. In this embodiment, the vertical straight scraper 28 uses a nickel-based high-temperature alloy, which has excellent high-temperature resistance and wear resistance. Under the movement control of the gantry crane, the loading container moves close to the corner between the bottom and the side wall of the zinc pot, and at the same time, the horizontal scraper 25 drives the vertical straight scraper on the slide bar 27 to move. The scrapers 28 rotate slowly together. When the slide bar 27 drives the vertical straight scraper 28 to contact the side wall of the zinc pot, the rotating vertical straight scraper 28 continuously scrapes off the zinc slag remaining in the corner of the zinc pot. When the vertical straight scraper 28 made of high-temperature resistant spring material is in close contact with the inner wall of the zinc pot, the vertical straight scraper 28 will be blocked by the inner wall of the zinc pot on the rotation path and bend and deform to avoid it, so as to avoid the vertical straight scraper 28 from scraping serious scratches on the inner wall of the zinc pot when it rotates through the inner wall of the zinc pot, thereby improving the scraping effect of the residual zinc slag in the zinc pot.

[0034] Example 2

[0035] like Figure 1-Figure 5 As shown, on the basis of Example 1, a baffle 5 is fixedly connected to the secondary guide rod 15 of this embodiment. When the horizontal scraper 25, the vertical oblique scraper 26, the vertical straight scraper 28 and the stirring blade 34 are stirring in the zinc pot, part of the boiling zinc liquid splashing upward will be intercepted by the baffle 5 in time to prevent the boiling zinc liquid from splashing into the external environment and causing damage to surrounding personnel and equipment.

[0036] like Figure 1-Figure 5 As shown, in this embodiment, an air jet pipe 6 is installed on the baffle 5, and the air jet pipe 6 is externally connected to a cold air flow blower; the air jet pipe 6 is configured as an annular structure, and the annular air jet pipe 6 is provided with a plurality of air outlet nozzle structures surrounding the filter plate 24; during the process of the outer filter basin 21, the inner filter basin 22 and the filter plate 24 salvaging the zinc slag and processing the filtrate of the zinc liquid, the external cold air flow blower continuously blows air downward, and the air flow can accelerate the speed at which the zinc liquid is filtered downward from the filter plate 24. Subsequently, before the zinc slag in the outer filter basin 21, the inner filter basin 22 and the filter plate 24 is placed in the recovery area, the air flow can also accelerate the cooling speed of the zinc slag, allowing the zinc slag to be recovered in a low-temperature state.

[0037] Example 3

[0038] like Figure 1-Figure 5 As shown, based on the embodiment 2, the inner filter basin 22 of this embodiment is slidably connected to a sliding frame 41; the sliding frame 41 is fixed to an inner scraper 42; a tension spring 43 is fixed between the sliding frame 41 and the baffle 5, and the tension spring 43 is initially in a stretched state. Under the action of the downward reverse tension of the stretched tension spring 43, the inner scraper 42 connected to the sliding frame 41 is pulled downward and tightly against the surface of the filter plate 24; when the zinc slag in the outer filter basin 21, the inner filter basin 22 and the filter plate 24 is lowered to the recovery area, the filter plate 24 is pulled downward. The inner filter basin 22 separates downward, and at the same time, the tension spring 43, which is initially in a stretched state, pulls the sliding frame 41 and the inner scraper 42 to move downward along with the filter plate 24, so that the inner scraper 42 remains in close contact with the surface of the filter plate 24. Then, the slow motor 31 drives the filter plate 24 to rotate slowly, and the stationary inner scraper 42 scrapes off the zinc residue remaining on the surface of the continuously rotating filter plate 24. The scraped filter residue falls downward along the inclined surface of the filter plate 24 to the recovery area, completing the cleaning of the zinc residue remaining on the surface of the filter plate 24.
