Description

[0002] In the actual bolt processing and manufacturing work, bolts are important connecting components, and their own metal properties are required to be high. In the casting process of bolt blanks, molten iron is required for casting. Molten iron is the key to casting, and impurities in molten iron directly affect the quality of bolts. After the molten iron is discharged into the ladle, it is usually necessary to spread an impurity remover, also called a sand remover, to remove impurities and absorb them, and then use tools manually to scoop them out. The current mixed molten iron separation device does not have comprehensive sand removal discharge and absorption, which is not convenient for uniform spreading and dispersion, and is likely to cause impurities in the local molten iron. At the same time, it is not convenient for molten iron recovery.

[0045] like Figure 5 , Figure 7 and Figure 8As shown, the filtering conveyor 4 includes a filtering auger 401 fixedly mounted on the inner side of the separation mounting cylinder 203; the filtering auger 401 is used to transport the removed sand; a fixing plate 403 is fixedly mounted on the right separation sliding frame 201, and a filtering fixing sheet 402 is fixedly mounted on the fixing plate 403; the filtering fixing sheet 402 is an arc-shaped structure; the filtering fixing sheet 402 is attached to the inner side of the separation mounting cylinder 203; the top of the filtering fixing sheet 402 is attached to the filtering auger 401; a row of through grooves is provided on the filtering fixing sheet 402; the row of through grooves provided on the filtering fixing sheet 402 is used to filter out excess molten iron in the removed sand; the filtering conveyor 4 can be used to collect the feed trough In addition to the sand and impurities discharged from 204, the excess molten iron can be filtered out by using the filter fixing plate 402, avoiding the waste of molten iron caused by traditional manual salvage.

During the process, the position of the filter fixing plate 402 remains unchanged, and the filter auger 401 is driven by the separated installation cylinder 203 to rotate in real time to discharge impurities.

[0046] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 and Fig.10As shown, the slag removal discharge member 5 includes two sliding blocks 501 slidably mounted on the ladle 101; the ends of the two sliding blocks 501 are respectively fixedly mounted on the sides of the two separation sliding frames 201; the other ends of the two sliding blocks 501 are respectively fixedly mounted on the sliding shaft frame 102; a baffle 5011 is fixedly mounted between the two sliding blocks 501; a material box frame 502 is fixedly mounted on the two sliding blocks 501 by bolts; a material box 503 is fixedly mounted on the material box frame 502, and a discharge nozzle 5031 is provided at the bottom of the material box 503; the discharge nozzle 5031 passes through the material box frame 502; the baffle 5011 is used to promote the removal of debris discharged by the discharge nozzle 5031; the slag removal discharge member 5 also includes an alarm light 504 fixedly mounted on the side of the material box 503; an alarm limit plate 505 is fixedly mounted on the material box 503; the alarm limit plate 505 is aligned with the liquid level detection part 7; the outward expansion conveying device 6 includes a counter-acting auger 601 rotatably connected to the two sliding blocks 501 ; The opposing auger 601 is provided with opposite spiral blades on both sides; the opposing auger 601 is used to discharge the two sides of the debris removal box; the homogenizing motor 602 is fixedly installed on the left sliding block 501; the output shaft of the homogenizing motor 602 is connected to the end of the opposing auger 601; the discharge nozzle 5031 is located in the middle of the opposing auger 601, and the slag removal discharge part 5 is used, which can facilitate the staff to fill the debris removal sand for debris removal work, and at the same time, the opposing auger 601 can be used to transport the debris removal sand to be evenly spread on The surface of molten iron can avoid omissions on the surface of molten iron, which would cause incomplete impurity removal. At the same time, evenly spreading the removed sand on the actual surface of molten iron can also help to keep the molten iron warm, improve the quality of the impurity removal process, and reduce impurities in the molten iron. The baffle 5011 plays the role of limiting the removed sand, which is convenient for the removed sand to be better transported to both sides. The sliding shaft frame 102 is pulled to control the opposing auger 601 and the scoop box 301 to move on the molten iron liquid surface, so that the removed sand can be fully spread on the molten iron liquid surface.

[0047] like Fig.11 As shown, the liquid level detection unit 7 includes an elevation sliding column 701 slidably mounted on the material box frame 502; a floating shell 702 is fixedly mounted at the bottom of the elevation sliding column 701; the floating shell 702 is a hollow structure; the floating shell 702 is used to float on the molten iron; a micro switch 703 is fixedly mounted on the top of the elevation sliding column 701; the micro switch 703 is aligned with the alarm limit plate 505; the micro switch 703 is electrically connected to the alarm light 504; the elevation sliding column 701 is used to prevent the molten iron from overflowing the ladle 101.

The alarm limit plate 505 can be used to control the alarm light 504 to light up and alarm, prompting the staff to stop adding molten iron.

[0048] A method for using a mixed molten iron separation device:

[0049] 1) Introduce molten iron into the ladle 101, put impurity-removing sand into the material box 503, start the homogenizing motor 602 to drive the opposing auger 601 to rotate, and the opposing auger 601 transports the impurity-removing sand in the middle to both sides, start the separation drive motor 202, and drive the six scooping boxes 301 to rotate on the molten iron liquid surface to salvage impurities;

[0050] 2) Pull the sliding shaft frame 102 to control the opposing auger 601 and the scooping box 301 to move on the molten iron liquid surface;

[0051] 3) When the molten iron is introduced into the ladle 101, the alarm light 504 lights up to alarm, and the staff stops adding the molten iron.

[0052] The working principle provided by the present invention is as follows: first, molten iron is introduced into the ladle 101, and then the debris removal sand is put into the material box 503, and the debris removal sand is discharged through the discharge nozzle 5031 and falls into the middle of the opposing auger 601, and the homogenizing motor 602 is started to drive the opposing auger 601 to rotate, and the opposing auger 601 transports the debris removal sand in the middle to both sides. During the process, the baffle 5011 plays a role of limiting the debris removal sand, so that the debris removal sand can be better transported to both sides. During the process, the sliding shaft frame 102 is pulled to control the opposing auger 601 and the scooping box 301 to move on the molten iron liquid surface, so that the debris removal sand can be fully spread on the molten iron liquid surface; after adding molten iron to the ladle 101, the separation drive motor 202 is started to drive the separation installation cylinder 203 to rotate, driving the six scooping boxes 301 to rotate on the molten iron liquid surface to salvage impurities, and the scooping boxes 301 cooperate with the scooping isolation rod 302 to filter out the debris removal sand. After some of the molten iron is removed, as the scooping box 301 rotates, the sand and impurities fall into the feed trough 204 under the action of gravity, and are collected by the separation installation cylinder 203 after passing through the feed trough 204. The six scooping boxes 301 can be rotated and salvaged in sequence; when the separation installation cylinder 203 rotates, as the scooping box 301 introduces the sand and impurities mixed with the molten iron into the filter fixing plate 402 through the feed trough 204, the molten iron is filtered by the through groove on the filter fixing plate 402 and then dripped into the inside of the molten iron ladle 101 again from the feed trough 204 at the bottom. During the process, the position of the filter fixing plate 402 remains unchanged, and the filter auger 401 is driven by the separation installation cylinder 203 to rotate in real time, so as to discharge the impurities. When the separation drive motor 202 drives the scooping box 301 to rotate counterclockwise upward for salvage, the spiral blades of the filter auger 401 transport the sand and impurities from left to right for discharge;

[0053] When molten iron is introduced into the ladle 101, it floats on the liquid surface through the floating shell 702. As the liquid level continues to rise, the buoyancy control elevation sliding column 701 rises until the elevation sliding column 701 drives the micro switch 703 to be squeezed to the alarm limit plate 505. The alarm light 504 can be controlled by the micro switch 703 to light up and alarm, prompting the staff to stop adding molten iron.

[0054] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
