Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ladle cleaning equipment, in particular to an aluminum liquid ladle cleaning machine. Background Art

[0002] Ladle is a kind of turnover equipment commonly used in the metallurgical industry. It is a large sealed container made of steel shell and lined with refractory material to extract smelted liquid aluminum, magnesium and other metals from the electrolytic cell and transport them to other places. Aluminum molten ladle is one of them, which is mainly used for the transportation of aluminum. In daily use, the inner wall of aluminum molten ladle will inevitably have metal residues to form residues or other pollutants. In order to avoid contamination of the next liquid metal, the aluminum molten ladle needs to be cleaned with a ladle cleaning machine after each use.

[0003] The ladle cleaning machine mainly includes a clamping device and a rotary drilling system. The rotary drilling system includes a feeding system and a cutter disc. The cutter disc moves in the ladle to scrape off the attachments on the inner wall of the ladle. The cutter disc is covered with a protective cover to prevent debris from splashing.

[0004] The knives on the traditional knife disc are mostly distributed in a five-pointed star shape, so that during the daily cleaning process, when the ladle cleaning machine is at the maximum position (close to the bottom wall of the ladle), it is impossible to completely clean the residual waste at the bottom. The aluminum ladle needs to be lifted out of the ladle cleaning machine after the cleaning is completed. It takes about 20 hours for the staff to enter the ladle for secondary cleaning after the temperature inside the ladle drops. This not only increases the cleaning time and prolongs the waiting period between the two uses of the aluminum ladle, but also poses a great safety hazard when the staff enters and exits the aluminum ladle. When the staff cleans the residual waste outside, a lot of dust will be generated, which seriously affects the health of the staff.

[0005] To this end, the utility model provides a molten aluminum ladle cleaning machine to solve the problem that common ladle cleaning machines do not clean thoroughly. Utility Model Content

[0031] The following will be combined with the attached embodiment of the utility model Figure 1-10 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0032] In order to solve the problems existing in the prior art, the present embodiment provides an aluminum molten ladle cleaning machine, including a clamping device for fixing the ladle and a rotary drilling system for cleaning debris, the rotary drilling system includes a movable frame 1, a protective cover 2 is driven by a hydraulic system in the movable frame 1, a cutter disc 3 is rotatably installed at the end of the protective cover 2, and also includes a scraper 4, the bottom end of the scraper 4 is arc-shaped, and a handle 5 is provided at the upper end, and the outer wall of the protective cover 2 is provided with a first window door that can be opened and closed for the scraper 4 to extend into.

[0033] Principle details of this embodiment:

[0034] A notch is cut at a suitable position of the shield 2, and the cut steel plate is connected to the shield 2 through a hinge to form a first window door, and a handle and a bolt are welded to realize the opening and closing and locking functions. A steel pipe and a small piece of steel plate are cut and welded at a suitable angle to form a scraper 4, the bottom end of the scraper 4 is arc-shaped, and a handle 5 is provided at the upper end. The handle 5 is provided with a heat-insulating material to avoid burns.

[0035] When in use, the molten aluminum ladle is hoisted and firmly clamped on the clamping device, and the hydraulic system moves, so that the cutter disc 3 gradually penetrates into the molten aluminum ladle. As the cutter disc 3 rotates rapidly, the inner wall of the molten aluminum ladle is scraped and cleaned.

[0036] After the aluminum ladle cleaning machine has finished working, the staff opens the first window door and extends the scraper 4 into the aluminum ladle to clean the residual waste left after the ladle cleaning machine has cleaned. In this way, the staff can operate directly on the ground without entering the aluminum ladle, lifting the aluminum ladle away from the aluminum ladle cleaning machine, or waiting for the aluminum ladle to cool before proceeding to the next step, thereby saving working time, shortening the aluminum ladle cycle, and avoiding the accidental risks caused by personnel entering and exiting the aluminum ladle and reducing damage to the health of the staff.

[0037] The bottom of the scraper 4 is cut into an arc shape (the inner wall of the aluminum molten ladle is round) so that the scraper 4 can better contact with the inner wall of the aluminum molten ladle, thereby achieving the purpose of cleaning the residual waste inside the aluminum molten ladle as much as possible.

[0038] In this embodiment, the handle end of the scraper 4 is separated from the grip 5, and the handle end is provided with an internal threaded hole. The grip 5 is provided with a threaded column, so that the length of the scraper 4 can be extended to use different depth lifting bags or usage scenarios, thereby improving the convenience and practicality of the equipment.

[0039] In a further embodiment of the present scheme, the clamping device includes three bases 6 distributed in a triangle, and each opposite side of the three bases 6 is provided with a clamping seat adapted to the outer wall of the lifting bag; a plurality of brackets 7 are provided on the side of the base 6, and a pressure rod 8 is rotatably installed on each bracket 7, and a first hydraulic rod 8 is rotatably installed on the side wall of the bracket 7, and the output end of the first hydraulic rod 8 is rotatably connected to the side wall of the pressure rod 8.

[0040] When in use, the molten aluminum ladle is hoisted onto the base 6, and then the first hydraulic rod 8 is contracted so that the end of the pressure rod 8 is against the side wall of the molten aluminum ladle, thereby fixing the ladle.

[0041] Preferably, five bases 6 are provided, four of which are symmetrically distributed in pairs and one is provided on the symmetry line. Figure 3 As shown, the support area is increased and the stability of the clamping support is improved.

[0042] In a further embodiment of the present invention, a pressure hammer 9 is rotatably mounted at the end of the pressure rod 8, and the bottom end of the pressure hammer 9 is arc-shaped. Under its own weight, the arc-shaped end of the pressure hammer 9 always faces downward, and the contact area with the aluminum molten ladle is increased by the pressure hammer 9, thereby increasing the limit stability and avoiding force concentration.

[0043] In a further embodiment of the present invention, a sealing cover 10 is embedded in the end of the movable frame 1, the protective cover 2 is located in the sealing cover 10, and a second window door that can be opened and closed is provided on the side wall of the sealing cover 10, and the second window door corresponds to the first window door. During the cleaning operation, the sealing cover 10 is pressed against the aluminum molten ladle port to seal the aluminum molten ladle port to prevent debris from splashing.

[0044] In this embodiment, the moving frame 1 can be moved, and the sealing cover 10 moves with the moving frame 1 and abuts against the aluminum molten ladle port, or the moving frame 1 can be kept stationary, and a second hydraulic rod 8 is arranged in the moving frame 1, and the sealing cover 10 is controlled to move parallel to the aluminum molten ladle port by the second hydraulic rod 8. The accompanying drawings only show the movement of the moving frame 1.

[0045] In a further embodiment of the present solution, due to the presence of the sealing cover 10, the side wall of the shield 2 can be hollowed out, eliminating the need to cut and set the first window, while reducing the load on the hydraulic system.

[0046] In a further embodiment of the present solution, the knife disc 3 includes a disc seat 301, and a plurality of scrapers 302 are arranged in a circular array on the end surface of the disc seat 301, and the tail ends of the scrapers 302 extend to the outer edge surface of the disc seat 301. The tail ends of the scrapers 302 are in contact with the inner wall of the molten aluminum ladle and have an arc shape that matches the bottom end of the molten aluminum ladle, so that the scrapers 302 are in full contact with the inner wall of the molten aluminum ladle, avoiding the existence of cleaning dead corners, and thus eliminating the need for secondary manual cleaning.

[0047] In a further embodiment of the present scheme, a hollow connecting seat 11 is provided on the side of the cutter disc 3 facing the interior of the protective cover 2, and the connecting seat 11 is driven by a motor fixed on the inner wall of the protective cover 2. A vacuum cleaner 12 is embedded in the connecting seat 11, and the suction port of the vacuum cleaner 12 passes through the axis of the cutter disc 3, and the storage box of the vacuum cleaner 12 is located at the end of the connecting seat 11, and the side wall of the storage box of the vacuum cleaner 12 is provided with an openable and closable drawer for discharging debris.

[0048] When in use, the motor drives the connecting seat 11 to rotate, and the connecting seat 11 drives the cutter disc 3 to rotate at the end of the protective cover 2, so that the cutter disc 3 rotates and scrapes; and under the action of the scraper 302, a sealed cavity is formed between the disc seat 301 and the bottom wall of the aluminum liquid lifting bag, and the vacuum cleaner 12 is started to form a negative pressure in the sealed cavity, so that the scraped debris is collected into the storage box, which saves the subsequent cleaning process and avoids the interference or influence of the fallen debris with the scraper 302.

[0049] In this embodiment, since the suction port of the vacuum cleaner 12 passes through the axis of the disc seat 301, a transverse scraper 302 is provided at this position to avoid a cleaning dead angle at the axis position.

[0050] In a further embodiment of the present scheme, the scraper 302 is tilted toward the direction of rotation to form a scraping inclination angle, which can scrape more cleanly relative to the vertical bottom wall of the aluminum molten ladle; the scraper 302 is not distributed radially along the disc seat 301, that is, the cleaning line length of a single scraper 302 is extended, so that multiple scrapers 302 are superimposed to improve the cleaning effect; and the scraped debris can be guided to move toward the suction port of the vacuum cleaner 12 to accelerate the discharge of the debris.

[0051] In this solution, a plurality of support rods 13 are evenly distributed on the side wall of the shield 2. When the cutterhead 3 is stored, the end of the support rod 13 abuts against the inner wall of the sealing cover 10; when the cutterhead 3 is rotary excavating, the end of the support rod 13 abuts against the inner wall of the aluminum molten ladle; the support rods 13 provide auxiliary support to the shield 2, which can reduce the load burden of the hydraulic system and guide the cutterhead 3 stably to prevent the cutterhead 3 from shaking and deviating during rotary excavation.
