Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing equipment, in particular to a continuous slag scooping device for an aluminum liquid filter box. Background Art

[0002] The aluminum liquid filter box is a commonly used equipment in the aluminum product manufacturing process. In the aluminum casting process, the purity of the aluminum liquid is related to the metallurgical quality during casting. Using a filter plate to filter and remove impurities in the aluminum liquid is the most common filtering method. Usually, the filter plate is placed directly in the aluminum liquid flow channel for filtering.

[0003] The publication number in the existing public technology is: CN217290401U. A slag cleaning device for aluminum alloy casting solves the problem that the slag cleaning in the existing technology is often done by manual scooping, which results in incomplete slag cleaning and low efficiency. A slag cleaning device for aluminum alloy casting includes an aluminum liquid barrel, the bottom of which is fixedly connected to a base, a suction pump is installed inside the base, and a return pipe is fixedly passed through one side of the aluminum liquid barrel. The utility model turns on the suction pump inside the base, and sucks the aluminum liquid in the inner cavity of the aluminum liquid barrel into the inner cavity of the filter box through the suction pipe for filtration, and discharges the aluminum liquid into the inner cavity of the aluminum liquid barrel again through the return pipe. The positioning plate is pushed out of contact with the mounting groove, and the filter frame can be removed to clean the slag, thereby improving the efficiency of slag cleaning and facilitating the user to uniformly collect and clean the slag, while also preventing the aluminum liquid from being carried out during cleaning.

[0004] However, the above patent still has certain disadvantages when in use: it can remove and collect impurities in the aluminum liquid through the filter frame, but when cleaning the filter frame later, the device needs to be stopped before the corresponding maintenance work can be carried out, otherwise the aluminum liquid will leak, which has a great impact on the operation and is not conducive to continuous slag removal operations. The use effect is not very ideal.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

One end of the adjusting disk 23 is located on the surface of one side inside the slag removal box 17 and is connected to a motor 27 through gear meshing. One end of the motor 27 is connected to a gear disk and teeth are provided on the surface of the adjusting disk 23. The two can mesh and rotate with each other.

[0032] In one embodiment, an alarm 8 is provided in the middle position of the other side surface of the aluminum liquid filter box body 1. The alarm 8 consists of a buzzer and a flashing light. A controller 6 is fixedly installed above the alarm 8 at the top position of the surface of the aluminum liquid filter box body 1. The alarm 8 can emit light and sound to remind personnel to deal with the residue and impurities inside the slag removal barrel 20 after they are collected to a certain extent. Frequent manual visual observation is no longer required, which can reduce the labor intensity of personnel.

[0033] In one embodiment, the bottom surface of the upper collecting hopper 5 is connected to the conveying pipe 14 through a circulation pipe 28 that passes through one side of the slag removal box 17 .

[0034] In one embodiment, side scrapers 9 are symmetrically provided in the middle position of the surface of the drive shaft 4, and bottom scrapers 12 are symmetrically provided on both sides of the bottom end of the surface of the drive shaft 4. The bottom scrapers 12 and the side scrapers 9 can disturb the aluminum liquid on the one hand, and on the other hand, the residue on the inner wall and the bottom of the box can be turned up, which is convenient for the subsequent extraction and use of the suction nozzle 13, and facilitates more thorough slag removal of the residue at the bottom.

[0035] In one embodiment, liquid inlets 2 are symmetrically installed on both sides of the top surface of the aluminum liquid filter box body 1. The arrangement of the liquid inlet 2 facilitates the introduction and use of the aluminum liquid to be processed.

[0036] In one embodiment, a base 11 is fixedly installed on the bottom surface of the aluminum liquid filter box body 1, and the device can be fixed by the base 11 to enhance the stability of the overall use.

[0037] In one embodiment, a re-liquidation pipe 7 is fixedly installed on the surface of one side of the interior of the aluminum liquid filter box body 1 below the upper collecting hopper 5, and one end of the re-liquidation pipe 7 is connected to the aluminum liquid pump 15 located at the bottom end of one side of the interior of the aluminum liquid filter box body 1, and one end of the aluminum liquid pump 15 passes through one side of the aluminum liquid filter box body 1 and is connected to the re-flow pipe 16 located at the bottom surface of the slag removal box 17.

[0038] In one embodiment, the pore size on the surface of the filter plate 22 gradually becomes smaller. The change in pore size is to better filter out the residue and impurities contained in the aluminum liquid, thereby improving the overall slag removal effect.

[0039] Working principle: In actual use, personnel can add the aluminum liquid that needs to be processed into the aluminum liquid filter box body 1 through the liquid inlet 2. At this time, the falling aluminum liquid will first fall into the upper collecting hopper 5 and be discharged into the deslagging box 17 along the flow pipe 28 set on the internal bottom surface. At this time, the falling aluminum liquid flows into the deslagging cylinder 20 through the discharge pipe 26, and is filtered and deslagging by the multiple groups of filter plates 22 therein for multiple times to ensure the purity of the aluminum liquid. Then, the aluminum liquid that has completed the deslagging will enter along the reflow pipe 16 and then be pumped through the aluminum liquid pump 15. The aluminum liquid is discharged into the re-liquid pipe 7, and then the operation of the motor 3 can drive the drive shaft 4 to rotate, thereby driving the side scraper 9 and the bottom scraper 10 to rotate continuously, which can disturb the aluminum liquid on the one hand and turn over the residue on the inner wall and the bottom of the box on the other hand. At the same time, the operation of the suction pump 25 continuously pumps the aluminum liquid containing the residue into the deslagging box 17 for two or more times through the suction nozzle 13 to filter and remove impurities again, thereby improving the purity of the aluminum liquid. Then, during the reciprocating filtration process of the aluminum liquid, the surface of the filter plate 22 The residual slag gradually increases, and at this time the weight detected by the weight sensor 19 will reach a preset range (by controlling the amount of aluminum liquid flowing into the liquid inlet 2 per unit time and the amount of aluminum liquid extracted by the suction pump 25, the weight increase caused by the aluminum liquid entering the slag removal barrel 20 can be kept in a relatively constant range, preventing the weight from increasing to a preset range due to the entry of aluminum liquid, resulting in erroneous operation of the device). At this time, the buzzer and flashing light inside the alarm 8 will be triggered to prompt personnel to take timely measures. Personnel no longer need to frequently observe the processing and collection status of the slag removal box 17, which reduces the labor intensity of personnel. At the same time, the motor 27 can drive the adjusting disk 23 to rotate through the gear plate on the surface, so that the drain pipe 26 can continue to perform slag removal operations toward another group of unused slag removal barrels 20, which is convenient for personnel to clean the slag removal barrels 20 after collection. There is no need to perform maintenance, which reduces the impact on the operation of the device. At the same time, the aluminum liquid can effectively improve the overall processing effect through multiple slag removals. The device as a whole has the advantages of good slag removal effect, multiple removals, and small operational impact.
