Description

Technical Field

[0001] The invention belongs to the technical field related to molten iron casting, and in particular relates to a device and method for continuous inoculation of molten iron casting. Background Art

[0002] Molten iron is a high-temperature, liquid metal solution containing impurities such as carbon, silicon, manganese, phosphorus, and sulfur extracted from iron ore through a reduction process. Under normal circumstances, molten iron can be used for further smelting purposes, including molten steel, cast iron, ferroalloys and other products. In order to make the molten iron and cast iron have good fluidity, reduce the shrinkage of castings, improve processing performance, and reduce residual stress, inoculants are added during molten iron processing. Inoculation treatment is a treatment process in which a small amount of a certain substance is added to the molten metal before or during pouring to affect the nucleation process of the molten metal, thereby changing its solidification characteristics. For cast iron, the purpose of inoculation is to increase the graphite core in the molten iron so that the eutectic solidifies, especially the precipitation of graphite can start at a relatively small degree of supercooling, the result is to increase the tendency of graphite precipitation and obtain evenly distributed fine graphite, so that the cast iron has good mechanical properties and processing properties. At the same time, according to the existing public document CN110355338B, in order to facilitate the addition of inoculants to the molten iron, a corresponding inoculation device is required.

[0003] Therefore, when the currently used device is used, it is unable to drive the molten iron furnace to automatically move in batches to the position directly below the splash-proof box, so that the molten iron and the inoculant cannot be put in synchronously, and thus it is impossible to realize automatic and continuous inoculation of the molten iron. At the same time, when the inoculant is added to the molten iron, the molten iron will be poured into the molten iron furnace, but in the process of pouring the molten iron, the molten iron continuously enters the molten iron furnace, and when the existing equipment adds the molten iron furnace, most of them directly pour the inoculant into the molten iron at one time. Therefore, the existing device does not have the ability to meter the inoculant according to the amount of molten iron input, and cannot realize accurate quantitative addition of the inoculant. To this end, we provide a casting molten iron continuous inoculation device and method to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a device and method for continuous inoculation of molten iron in castings, which drives multiple molten iron furnaces to automatically move in batches to a position directly below a splash-proof box through a rotating component and a stroke component, and controls the simultaneous input of molten iron and inoculant to achieve automatic and continuous inoculation process treatment of the molten iron.

[0007] The present invention is further configured such that a positioning frame fixedly connected to the wheel motor base is arranged on the left side of the rotating block, and a collar at the end of the positioning frame is sleeved on the fixed point rod.

[0008] The present invention is further configured such that an L-shaped lifting lug is fixed to the peripheral side wall of the rotating block directly above each stroke plate, and a rack is fixed to the upper end surface of the transverse portion of each L-shaped lifting lug.

[0009] The present invention is further configured such that a hanging ear matched with the L-shaped hanging ear is fixed on the side wall of the molten iron furnace corresponding to the L-shaped hanging ear, and a tooth opening for meshing with the rack is formed on the lower end surface of the hanging ear.

[0010] The present invention is further configured such that two symmetrically arranged slide rails are fixed to the upper end surface of each travel plate, the magnetic plate is located between the two slide rails, and the travel block is sleeved on the slide rail through a slide opening opened on the lower end surface.

[0011] The present invention is further configured such that the storage box and the splash-proof box are bolted together via a mounting plate, a bending rod fixedly connected to the side wall of the splash-proof box is provided directly below the mounting plate, the pull rope is passed around the surface side of the bending rod in sequence, and the storage box is bolted to the travel plate via a fixed L-shaped plate.

[0012] The present invention is further configured such that an inclined adding pipe connected to the inside of the vertical pipe is fixed in the middle of the vertical pipe, the lower end of the adding pipe is located directly above the splash-proof box, and the blocking rod is located in the internal position between the vertical pipe and the adding pipe.

[0013] The present invention is further configured such that a limit ring is fixed to the lower end face of the vertical tube, and the inner diameter of the limit ring is smaller than the inner tube diameter of the vertical tube, and a return spring abutting against the upper end face of the limit ring is fixed to the lower end face of the blocking rod.

[0014] The present invention is further configured such that rotating rods are fixed on both sides of the opening of the splash-proof box at the inclined plate, and rotating holes are opened on the side walls at the opening of the splash-proof box at positions corresponding to the rotating rods. The rotating rods are rotatably set in the corresponding rotating holes, and a plurality of arc springs uniformly arranged in a linear manner are fixed to the lower end surface of the inclined plate, and the other ends of the arc springs are in contact with the vertical surface of the splash-proof box, and a conical cylinder is fixedly connected to the lower end surface of the splash-proof box.

[0015] The present invention provides a method for continuous inoculation of molten iron, which is implemented by the following steps:

[0016] S1: The rotary motor, cylinder 1, cylinder 2 and electromagnet are used in conjunction with sensors to control the operation of a single electromagnet, so that the travel block slides along the travel plate, and then the travel block drives the molten iron furnace to move to the position directly below the splash box;

[0017] S2: Pour the molten iron from the upper position of the splash-proof box, and then the molten iron will push the inclined plate, causing the inclined plate inside the splash-proof box to rotate downward, and the inclined plate outside the splash-proof box to rotate upward, and then the upwardly rotating part of the inclined plate drives the blocking rod to slide downward inside the vertical pipe through the pull rope;

[0018] S3: After the blocking rod is moved downward from the position where the vertical tube and the adding tube meet, the inoculant in the storage box will slide from the position of the vertical tube to the adding tube, and then slide from the adding tube into the molten iron furnace;

[0019] S4: After the tilting plate is tilted, the molten iron will slide from the splash box and the conical tube into the molten iron furnace, and the inoculant will also enter the molten iron furnace at this time, so that the inoculant will continue to inoculate the poured molten iron;

[0020] S5: After the pouring of molten iron stops, the inclined plate will be reset, and the pulling of the pull rope will stop, so that the blocking rod moves upward inside the vertical pipe, so that the blocking rod blocks the position of the adding pipe and the vertical pipe;

[0021] S6: At this time, another electromagnet is controlled to work, and then the electromagnet will push the travel block to move in the opposite direction on the travel plate, and control the second cylinder to work with the electromagnet, so that the hanging ear on the side wall of the molten iron furnace is hung on the L-shaped hanging ear, so that the upper and lower positions of the molten iron furnace and the electric lock cover are consistent;

[0022] S7: At this time, the cylinder is controlled to extend and retract, so that the cylinder moves the electric lock cover to the upper position of the molten iron furnace, so that the electric lock cover is locked on the molten iron furnace. At this time, the rotary motor is controlled to work, so that the rotary motor will drive the molten iron furnace to move from one stroke block to another stroke block, so as to continuously incubate the molten iron in a circular manner.

[0023] The present invention has the following beneficial effects:

[0024] The rotary motor works to drive the molten iron furnace from one of the stroke plates to the upper end position of another stroke plate, and molten iron is poured into different molten iron furnaces. At the same time, the stroke block drives the molten iron furnace to move on the stroke plate, so that the molten iron furnace can be moved to the position directly below the splash-proof box. After the molten iron is poured into the splash-proof box, the inoculant inside the storage box will follow into the molten iron furnace. After the molten iron inside the molten iron furnace is replenished, it will be reset by the stroke block and driven to rotate by the rotary motor, so that the empty molten iron furnace moves to the stroke block consistent with the upper and lower positions of the splash-proof box, and the full molten iron furnace will turn away from the stroke block at that position, thereby driving multiple molten iron furnaces to automatically move in batches to the position directly below the splash-proof box, thereby realizing automatic and continuous inoculation process treatment of the molten iron.

[0025] Pour molten iron downward from the upper position of the splash-proof box, so that the molten iron will impact the inclined plate inside the splash-proof box, causing the inclined plate in the splash-proof box to rotate and tilt, thereby driving the inclined plate outside the splash-proof box to rotate upward and pull the pull rope, so that the pull rope drives the blocking rod to move downward from the position between the vertical tube and the adding tube. At this time, the inoculant inside the storage box will slide from the position of the vertical tube to the adding tube, and the inoculant will fall accurately into the molten iron furnace through the adding tube, so that the dosage of the inoculant can be added according to the amount of molten iron poured, so as to achieve precise delivery.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 , which is the first embodiment of the present invention, provides a casting molten iron continuous inoculation device, which drives multiple molten iron furnaces 301 to automatically move to the position directly below the splash-proof box 402 in batches through the rotating component 100 and the stroke component 200, and controls the synchronous input of molten iron and inoculant to realize automatic and continuous inoculation process of molten iron. At the same time, the linkage between the inclined plate 403, the pull rope 406b and the blocking rod 406 is used, so that the inoculant can be metered according to the flow rate of molten iron input, so as to realize accurate and quantitative addition.

[0043] Specifically, it includes a rotary assembly 100, including a rotary motor 101, a rotating block 102 drivingly connected to the rotary motor 101, and a fixed rod 103 rotatably arranged on the upper end surface of the rotating block 102; a stroke assembly 200, including three stroke plates 201 evenly arranged in a ring shape along the circumference of the rotary motor 101 and three stroke blocks 202 respectively sliding on the upper end surface positions of the corresponding stroke plates 201; a mixing assembly 300, including a molten iron furnace 301 connected to the piston end of the cylinder 2 204 and an electric lock cover 302 for closing the upper port of the molten iron furnace 301; a continuous adding assembly 400, including a storage box 401 located at the right position of the rotary motor 101 and a splash-proof box 402 located at the front lower part of the storage box 401;

[0044] By setting and using the above-mentioned structure, the rotary motor 101 works to drive the molten iron furnace 301 to move from one of the stroke plates 201 to the upper end position of another stroke plate 201, so as to pour molten iron into different molten iron furnaces 301, and at the same time, the stroke block 202 drives the molten iron furnace 301 to move on the stroke plate 201, so that the molten iron furnace 301 can be moved to the position directly below the splash-proof box 402, and then after the molten iron is poured into the splash-proof box 402, the inoculant inside the storage box 401 will follow and enter the molten iron furnace 301. After the molten iron in the molten iron furnace 301 is replenished, it will be driven to reset through the stroke block 202, and the molten iron furnace 301 will be driven to rotate by the rotary motor 101, so that the empty molten iron furnace 301 moves to the stroke block 202 that is consistent with the upper and lower positions of the splash-proof box 402, and the full molten iron furnace 301 will be turned away from the stroke block 202 at this location and will be transported away by subsequent equipment.

[0045] according to Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig.11 The end of the fixed rod 103 is fixed with a cylinder 103a, the piston end of the cylinder 103a is fixed with a lifting ring 103a-1, the upper end surface of the travel block 202 is fixed with a cylinder 204, the upper end surface of the travel plate 201 is fixed with a magnetic plate 201a of the same length as the travel plate 201, the lower end surface of the travel block 202 is fixed with two inclined cylinders 202a arranged in an eight-shaped shape, and the interior of the inclined cylinder 202a is fixed with an electromagnet 203 that repels the magnetic plate 201a, and the upper end of the electric lock cover 302 Two symmetrically arranged curved rods 302a are fixed on the surface, the splash box 402 is in the same upper and lower positions as the end of one of the travel plates 201, an inclined plate 403 is rotated inside the splash box 402, a vertical pipe 401a is fixed at the outlet position of the lower end of the storage box 401, a blocking rod 406 used for gap matching is arranged inside the vertical pipe 401a, and the end position of the inclined plate 403 beyond the splash box 402 is fixedly connected to the bottom position of the blocking rod 406 by a set pull rope 406b;

[0046] When using the structure set above, after the molten iron furnace 301 moves to the position directly below the splash-proof box 402, the molten iron is poured downward from the upper position of the splash-proof box 402, so that the molten iron will impact the inclined plate 403 inside the splash-proof box 402, causing the inclined plate 403 inside the splash-proof box 402 to rotate and tilt, thereby driving the inclined plate 403 outside the splash-proof box 402 to rotate upward and pull the pull rope 406b, so that the pull rope 406b drives the blocking rod 406 to move downward from the position between the vertical tube 401a and the addition tube 401b, and at this time, the inoculant inside the storage box 401 will slide from the position of the vertical tube 401a to the addition tube 401b, and the inoculant will accurately fall into the molten iron furnace 301 through the addition tube 401b, so that the dosage of the inoculant can be added according to the amount of molten iron poured, so as to achieve accurate delivery;

[0047] At the same time, in order to control the movement of the molten iron furnace 301, the power supply of the electromagnet 203 can be controlled. Since the electromagnet 203 is fixed in the tilting cylinder 202a, and the tilting cylinder 202a and the magnetic plate 201a are arranged at an angle, when a single electromagnet 203 is powered on, the magnetic poles of the electromagnet 203 and the magnetic plate 201a will repel each other, and the position of the magnetic plate 201a will remain unchanged, which will push the electromagnet 203 to move, thereby driving the travel block 202 to move, so as to facilitate the sliding of the molten iron furnace 301.

[0048] Furthermore, after the cylinder 103a controls the lifting ring 103a-1 to move downward, the lifting ring 103a-1 will drive the curved rod 302a to move downward, and drive the electric lock cover 302 to move downward and assemble with the molten iron furnace 301. At this time, after the rotating block drives the molten iron furnace 301 to rotate open, the curved rod 302a on this electric lock cover 302 will be moved away from the position of the lifting ring 103a-1, and the curved rod 302a on the other electric lock cover 302 will be moved to the position directly above the lifting ring 103a-1. Therefore, this electric lock cover 302 can be controlled to open, and the cylinder can be controlled to drive the lifting ring 103a-1 to move upward, so that the molten iron furnace 301 can be opened.

[0049] Further, according to Figure 2 It can be seen that a positioning frame 104 fixedly connected to the base of the rotary motor 101 is provided on the left side of the rotating block 102, and the ring at the end of the positioning frame 104 is sleeved on the fixed rod 103. When the rotary motor 101 is working, the rotary motor 101 will drive the rotating block 102 to rotate. At this time, the ring is sleeved on the fixed rod 103, so that the ring limits the fixed rod 103, thereby ensuring that when the rotating block 102 rotates, the fixed rod 103 will not rotate with it, and ensuring that the cylinder 103a on the fixed rod 103 will not rotate.

[0050] Further, according to Figure 3 and Figure 4 It can be seen that two symmetrically arranged slide rails 201b are fixed to the upper end surface of each travel plate 201, the magnetic plate 201a is located between the two slide rails 201b, and the travel block 202 is mounted on the slide rail 201b through the slide opening 202b opened on the lower end surface. When the travel block 202 is moving, since the travel block 202 is mounted on the slide rail 201b through the slide opening 202b, the travel block 202 will slide along the slide rail 201b.

[0051] Further, according to Figure 5 It can be seen that the storage box 401 and the splash-proof box 402 are bolted together by the mounting plate 405, and a bending rod 404 fixedly connected to the side wall of the splash-proof box 402 is provided directly below the mounting plate 405. The pull rope 406b passes around the surface side of the bending rod 404 in sequence, and the storage box 401 is bolted to the travel plate 201 through a fixed L-shaped plate. The pull rope 406b is bent at multiple points by the bending rod 404, so that the inclined plate 403 drives the pull rope 406b to move, and the pull rope 406b can accurately drive the movement of the blocking rod 406.

[0052] It should be noted that the rotary motor 101, cylinder 1 103a, cylinder 2 204 and electromagnet 203 used are all controlled by an external control center. At the same time, multiple sensors are set up to control the rotary motor 101, cylinder 1 103a, cylinder 2 204 and electromagnet 203 to work synchronously, so that multiple electrical structures can be used in conjunction with each other. Example 2

[0053] See also Figure 2 and Fig.11 On the basis of Example 1, this embodiment uses the L-shaped lifting lug 102a and the hanging lug 301a in combination to ensure stable rotation of the molten iron furnace 301.

[0054] Specifically, an L-shaped lifting lug 102a is fixed to the side wall of the rotating block 102 located directly above each travel plate 201, and a rack 102a-1 is fixed to the upper end surface of the lateral portion of each L-shaped lifting lug 102a. A hanging lug 301a used in conjunction with the L-shaped lifting lug 102a is fixed to the side wall of the molten iron furnace 301 corresponding to the L-shaped lifting lug 102a, and a tooth opening 301a-1 used to mesh with the rack 102a-1 is provided on the lower end surface of the hanging lug 301a.

[0055] By setting and using the above structure, when the side of the L-shaped lifting ear 102a is in contact with the side of the hanging ear 301a, the control cylinder 204 works, so that the cylinder 204 pushes the molten iron furnace 301 upward, and controls the hanging ear 301a to move to the upper position of the L-shaped lifting ear 102a. At this time, the travel block 202 will continue to drive the molten iron furnace 301 to move an end distance, so that the hanging ear 301a moves to the upper position of the L-shaped lifting ear 102a. At this time, the control cylinder 204 retracts, so that the cylinder 204 drives the molten iron furnace 301 moves downward, so that the ear 301a will be stuck in the upper end position of the L-shaped ear 102a, and then the L-shaped ear 102a will support the ear 301a. At the same time, after the rotating block 102 rotates, the ear 301a will be driven to move through the L-shaped ear 102a, and thereby the molten iron furnace 301 will be driven to rotate. At the same time, the rack 102a-1 on the L-shaped ear 102a will be engaged with the tooth mouth 301a-1 on the end face of the ear 301a, ensuring that the ear 301a will not slide or deviate on the L-shaped ear 102a. Example 3

[0056] See also Figure 7 , Figure 8 and Fig.10 On the basis of Example 1, this embodiment uses a reset spring 406a to facilitate the control of the reset of the blocking rod 406 and realize the automatic closing of the storage box 401.

[0057] Specifically, an inclining adding pipe 401b connected to the inside of the vertical pipe 401a is fixed at the middle of the vertical pipe 401a, and the lower end of the adding pipe 401b is located directly above the splash box 402. The blocking rod 406 is located in the inner position between the vertical pipe 401a and the adding pipe 401b. A limiting ring 401a-1 is fixed to the lower end surface of the vertical pipe 401a, and the inner diameter of the limiting ring 401a-1 is smaller than the inner tube diameter of the vertical pipe 401a. A return spring 406a abutting against the upper end surface of the limiting ring 401a-1 is fixed to the lower end surface of the blocking rod 406.

[0058] Through the arrangement and use of the above-mentioned structure, when the pull rope 406b drives the blocking rod 406 to move downward in the internal position of the vertical tube 401a, the return spring 406a is limited by the limit ring 401a-1, so that the blocking rod 406 will compress the return spring 406a. At the same time, the end of the inclined plate 403 that exceeds the splash-proof box 402 is reset, and the pull rope 406b does not pull the blocking rod 406. At this time, the return spring 406a will push the blocking rod 406 to move upward, so that the blocking rod 406 will re-seal the position where the vertical tube 401a and the adding tube 401b are connected. Example 4

[0059] See also Figure 6 and Fig. 9 On the basis of Example 1, this embodiment pushes the inclined plate 403 by the arc spring 403b, so that the inclined plate 403 can reset itself.

[0060] Specifically, the inclined plate 403 is fixed with rotating rods 403a on both sides of the opening of the splash-proof box 402, and a rotating hole 402a is opened on the side wall of the opening of the splash-proof box 402 at a position corresponding to the rotating rod 403a. The rotating rod 403a is rotatably set in the corresponding rotating hole 402a, and a plurality of arc springs 403b uniformly arranged in a linear manner are fixed to the lower end surface of the inclined plate 403, and the other end of the arc spring 403b is in contact with the vertical surface of the splash-proof box 402, and the lower end surface of the splash-proof box 402 is fixedly connected with a conical cylinder 402b;

[0061] Through the setting and use of the above-mentioned structure, when molten iron is poured into the interior of the splash-proof box 402, the molten iron impacts the inclined plate 403, so that the inclined plate 403 rotates downward inside the splash-proof box 402 and compresses the arc spring 403b. Therefore, when the molten iron does not impact the inclined plate 403, the arc spring 403b pushes the molten iron to rotate upward, so that the inclined plate 403 is reset.

[0062] The present invention provides a method for continuous inoculation of molten iron, which is implemented by the following steps:

[0063] S1: The rotary motor 101, cylinder 1 103a, cylinder 2 204 and electromagnet 203 are used in conjunction with sensors to control the operation of a single electromagnet 203, so that the travel block 202 slides along the travel plate 201, and then the travel block 202 drives the molten iron furnace 301 to move to a position directly below the splash box 402;

[0064] S2: Pour the molten iron from the upper position of the splash-proof box 402, and then the molten iron will push the inclined plate 403, so that the inclined plate 403 inside the splash-proof box 402 rotates downward, and the inclined plate 403 outside the splash-proof box 402 rotates upward, and then the upwardly rotated part of the inclined plate 403 drives the blocking rod 406 to slide downward inside the vertical tube 401a through the pull rope 406b;

[0065] S3: After the blocking rod 406 moves downward from the position where the vertical tube 401a and the adding tube 401b meet, the inoculant in the storage box 401 slides from the vertical tube 401a to the adding tube 401b, and then slides from the adding tube 401b into the molten iron furnace 301;

[0066] S4: After the tilting plate 403 is tilted, the molten iron will slide from the splash box 402 and the conical tube 402b into the molten iron furnace 301, and the inoculant will also enter the molten iron furnace 301, so that the inoculant will continue to inoculate the poured molten iron;

[0067] S5: After the pouring of molten iron stops, the inclined plate 403 will be reset, and the pulling of the pull rope 406b will stop, so that the blocking rod 406 moves upward inside the vertical pipe 401a, so that the blocking rod 406 blocks the position of the adding pipe 401b and the vertical pipe 401a;

[0068] S6: At this time, another electromagnet 203 is controlled to work, and then the electromagnet 203 will push the travel block 202 to move in the opposite direction on the travel plate 201, and the cylinder 204 is controlled to cooperate with the electromagnet 203 to make the hanging ear 301a on the side wall of the molten iron furnace 301 hang on the L-shaped hanging ear 102a, so that the upper and lower positions of the molten iron furnace 301 and the electric lock cover 302 are consistent;

[0069] S7: At this time, the cylinder 103a is controlled to extend and retract, so that the cylinder 103a moves the electric lock cover 302 to the upper position of the molten iron furnace 301, so that the electric lock cover 302 is locked on the molten iron furnace 301. At this time, the rotary motor 101 is controlled to work, so that the rotary motor 101 will drive the molten iron furnace 301 to move from one stroke block 202 to another stroke block 202, so as to continuously incubate and recycle the molten iron.
