Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for cast iron machines, specifically to a return iron anti-mixing and recycling receiving chute for cast iron machines. Background Technology

[0002] Molten iron is continuously poured into iron blocks by a casting machine. Ideally, all the iron blocks should detach from the mold at the tail end of the machine and fall vertically into the iron block car. However, in actual production, due to adhesion to the inner surface of the mold, fluctuations in molten iron temperature, or uneven cooling, some iron blocks cannot be detached in time and instead continue to rotate with the steel chain until they fall below the casting machine, commonly known as "return iron." Once return iron falls to the ground, it not only requires secondary manual cleaning, which is labor-intensive and results in long downtime, but it is also prone to mixing with iron slag on the ground and iron blocks from different shifts or furnaces, causing cross-contamination of different grades and leading to quality complaints from customers. At the same time, the hot iron blocks splashing when they fall pose a risk of personal injury and fire, and increase dust and noise levels on site, making it difficult to meet environmental protection standards. Currently, most steel mills still use an open, free-falling method combined with manual sweeping to collect return iron, with only a few companies installing fixed inclined plates or simple chutes under the casting machine. These simplified solutions have obvious drawbacks: the width of the inclined plate is less than the width of the steel chain, so the return iron can still easily fall off from the side; there is no reinforcing structure, making it prone to deformation and weld cracking under high-temperature impact; and there is no auxiliary means to clear blockages when the iron blocks stick, requiring manual knocking, which poses a significant safety hazard. Therefore, existing technologies cannot effectively solve the quality and safety problems caused by the return iron falling to the ground, and there is an urgent need for a receiving device that can receive materials across the entire width, has reliable strength, automatically clears blockages, and is easy to install and maintain. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a return iron anti-mixing and recycling receiving chute for iron casting machines, which facilitates the collection of return iron.

[0004] This utility model achieves its purpose through the following technical solution: A return iron anti-mixing recycling chute for a casting iron machine includes a chute body, the width of which is equal to the width of the tail of the casting iron machine, and the chute body is inclined along the lower part of the tail of the casting iron machine to receive the return iron that falls off with the rotation of the chain belt due to failure to demold in time. Four hanging points are respectively set on both sides of the chute body. The chute body is suspended below the tail of the cast iron machine by four steel chains; Reinforcing ribs are provided on the outer side wall of the chute body to enhance the rigidity of the chute body; The vibrating motor is mounted on the back of the chute body via a motor mount. It is used to generate a vibrating force when there is a large amount of return iron or when it is stuck, so as to cause the return iron to slide down along the chute body. The slot is provided in the chute body. At the end, it is used to guide the returned iron into the iron block car to prevent the returned iron from falling to the ground and causing iron blocks of different grades to mix.

[0005] As a further limitation of this technical solution, the inclination angle of the chute body is 30° to 45° to ensure that the return iron slides smoothly under the action of gravity.

[0006] As a further limitation of this technical solution, the vibrating motor is an adjustable frequency vibrating motor, and its vibrating frequency and vibrating time can be adjusted remotely or locally according to the retention of the return iron.

[0007] As a further limitation of this technical solution, the reinforcing rib is an arc-shaped structure, which is welded to the outside of the chute body to prevent the chute from deforming due to long-term vibration.

[0008] As a further limitation of this technical solution, the hanging point is connected to an adjustable-length chain or screw assembly, which is used to adjust the vertical distance between the chute body and the steel chain of the casting machine, so as to ensure that the return iron falls accurately into the chute opening.

[0009] As a further limitation of this technical solution, the end of the slot is arc-shaped to facilitate the falling of the return iron.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are: 1. The width of the chute body is consistent with the width of the tail of the casting machine, so as to realize the full width reception of the return iron. The high temperature iron block slides directly into the iron block car, completely avoiding cross-contamination of grades caused by "first landing and then cleaning", and eliminating quality disputes from the source. 2. The trough back vibratory motor can automatically start and stop according to the amount of residue, replacing manual knocking, clearing blockages in a timely manner and without high-temperature splashing; the trough body is completely enclosed except for the outlet, dust and noise are reduced simultaneously, and the on-site working environment is significantly improved; 3. Reinforcing ribs increase the strength of the chute body, resist high temperature impact, and prevent deformation; the hanging point height can be freely adjusted as the chain belt droops, saving on manual cleaning costs.

[0015] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0018] like Figures 1-3 As shown, this utility model includes a chute body 3, the width of which is equal to the width of the tail of the casting machine 1, and the chute body 3 is inclined along the lower part of the tail of the casting machine to receive the return iron that has not been demolded in time and has fallen with the rotation of the chain belt; four hanging points 4 are respectively set on the two sides of the chute body 3, and the chute body 3 is suspended below the tail of the casting machine 1 by four steel chains 2. A reinforcing rib 5 is provided on the outer wall of the chute body 3 to enhance the rigidity of the chute body 3; a vibrating motor 8 is installed on the back of the chute body 3 through a motor base 7 to generate a vibrating force when there is a large amount of return iron or when it is stuck, so as to cause the return iron to slide down along the chute body 3; a slot 10 is provided at the end of the chute body 3 to guide the return iron into the iron block car 9 to prevent the return iron from falling to the ground and causing iron blocks of different grades to mix.

[0019] The chute body 3 is tilted at an angle of 30° to 45° to ensure that the return iron slides smoothly under the action of gravity. The vibrating motor 8 is an adjustable frequency vibrating motor, whose vibrating frequency and vibrating time can be adjusted remotely or locally according to the retention of the return iron.

[0020] As one embodiment, the vibratory motor is a universal excitation source for various vibrating machinery, widely used in industries such as mining, metallurgy, coal, power, building materials, chemicals, casting, light industry, food, pharmaceuticals, grain, cement, ports, railways, dust removal, coating, and PCB electroplating. It serves as the vibration source for various vibrating screens, vibrating feeders, vibrating finishing machines, compaction tables, and silo arch breaking and anti-blocking devices. It features lightweight, small size, convenient excitation force adjustment, high insulation and protection levels, and good synchronization when multiple units are used together. The company is dedicated to the research and development and production of special motors such as vibratory motors, torque motors, and speed-regulating motors.

[0021] A rapping motor consists of an adjustable eccentric block installed at each end of the rotor shaft. The excitation force is generated by the centrifugal force produced by the high-speed rotation of the shaft and eccentric blocks. Rapper motors have a wide vibration frequency range; only when the excitation force and power are properly matched can mechanical noise be reduced.

[0022] The reinforcing rib 5 is an arc-shaped structure that is welded to the outside of the chute body 3 to prevent deformation of the chute body due to long-term vibration. The hanging point 4 is connected to an adjustable chain or screw assembly, which is used to adjust the vertical distance between the chute body 3 and the steel chain 2 of the casting machine 1, so as to ensure that the return iron falls accurately into the chute opening 10.

[0023] In one embodiment, the chain material is 35CrMo, with a galvanized surface and a breaking tensile strength ≥40 kN, meeting the requirements of high temperature and impact conditions. The end of the chain is fixed by a U-shaped chain buckle. Its typical structure is a piece of steel plate stamped into a U shape, with pin holes or threaded holes on both sides. After the chain is placed in the groove, a pin or bolt is passed through it and locked, which can firmly clamp the two ends of the chain (or the chain and the outer link) together, realizing the positioning, tensioning or suspension functions. By adjusting different chain fixing positions, the vertical distance and angle between the chute body 3 and the steel chain 2 of the cast iron machine 1 can be adjusted.

[0024] In another embodiment, the screw assembly consists of a 35CrMo adjusting screw with left and right trapezoidal threads at both ends, a hexagonal turnbuckle nut, two locking back nuts, and upper and lower hinge joints. Rotating the turnbuckle nut allows the two ends of the screw to extend and retract synchronously, steplessly adjusting the vertical distance between the chute and the steel chain from 0 to 150 mm. After adjustment, tightening the back nuts self-locks and prevents loosening. The entire adjustment process requires no disassembly or assembly tools and can be completed by one person in 2 minutes.

[0025] The end of the slot 10 is an arc-shaped opening to facilitate the falling of the return iron.

[0026] As one embodiment, the end of the slot 10 is integrally stamped into a continuous arc-shaped opening, and the arc surface forms a tangential transition with the side wall of the carriage 9. When the return iron falls, it is smoothly thrown out along the tangential direction, avoiding splashing and bouncing caused by the collision of sharp corners. A 6 mm wear-resistant layer is welded on the inner side of the arc-shaped opening, which can resist the long-term erosion of the iron block and extend its service life.

[0027] Throughout this specification, the terms "an embodiment" or "an embodiment" mean that a specific feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of the disclosed subject matter. Therefore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment.
