Description

Technical Field

[0001] The utility model relates to the technical field of aluminum liquid casting chutes, in particular to an automatic flow control and low dross casting chute. Background Art

[0002] Aluminum ingot casting is a physical process of cooling and crystallizing liquid aluminum into solid aluminum ingots, which is an important link in the production of aluminum products and plays a crucial role in modern manufacturing. From building doors and windows, aerospace materials to automotive parts, aluminum ingot casting technology not only promotes the development of multiple industries, but also becomes an indispensable part of modern industry with its advantages of high efficiency, energy conservation and environmental protection.

[0003] At present, during the continuous casting of aluminum ingots, the aluminum liquid in the common chute flows into the casting chute body through a height difference, and then flows into the distributor through the casting chute body. When the aluminum liquid flows from the common chute into the casting chute body, the speed is very fast and it experiences a large height drop and scouring. Scouring and flowing will generate dross, and the dross exists in the aluminum liquid, resulting in the surface quality of the produced aluminum ingots not being guaranteed. Therefore, it is necessary to clean up the dross generated during the aluminum ingot casting process to ensure that the surface of the aluminum ingot in the mold is smooth.

[0004] However, in the prior art when salvaging dross, due to a large amount of dross generated during casting, the robot cannot completely salvage it, and manual secondary salvage is required, which is time-consuming and laborious. Moreover, due to the high environmental temperature during aluminum ingot casting, when manually salvaging dross, there will be a large potential safety hazard in the high-temperature environment; in addition, during the aluminum liquid casting process, it is necessary to control the flow rate of the aluminum liquid. Currently, it is controlled by manually blocking the furnace eye, and the direct distance between the furnace eye and the casting chute body is up to dozens of meters. When it is found that the flow rate is too large, even if the operation of blocking the furnace eye has been taken, the flow rate of the aluminum liquid in the common chute cannot be instantaneously reduced. At this time, the employee needs to press the emergency stop button to raise the casting chute body so that the aluminum liquid flows into the residual aluminum box. Once an operation error occurs, safety accidents such as aluminum overflow will occur and an explosion will occur. Summary of the Utility Model

[0005] The utility model provides an automatic flow control and low dross casting chute to solve the technical problems of unstable aluminum liquid flow rate and more dross during the aluminum ingot casting process in the prior art.

[0006] To solve the above problems, the automatic flow control and low dross casting chute provided by the utility model adopts the following technical solutions:

[0007] An automatic flow control and low dross casting chute, comprising:

[0008] The casting chute body is a ship-shaped chute connected to the aluminum storage container. A flow hole is provided between the casting chute body and the aluminum storage container. The flow hole is equipped with a plug so as to transport the aluminum liquid in the aluminum storage container to the casting chute body.

[0009] An aluminum storage container, one end of which is connected to the common chute, and the other end of which is connected to the casting chute body, the aluminum storage container is bent and extended from the common chute to the casting chute body, and the size of the end connected to the common chute is smaller than the size of the end connected to the casting chute body;

[0010] A casting spout is arranged at one end of the casting chute body and is a trumpet-shaped structure expanding outward from the casting chute body, and the end of the casting spout away from the casting chute body is bent downward;

[0011] The aluminum storage container is connected to a first diverter trough, the end of the first diverter trough facing away from the aluminum storage container is connected to the residual aluminum box, and the height of the first diverter trough is lower than the height of the end of the aluminum storage container connected to the common chute.

[0012] The beneficial effects of the automatic flow control low slag casting chute provided by the utility model are:

[0013] 1. By setting a first diverter trough connected to the residual aluminum box on the aluminum storage container, and making the height of the first diverter trough lower than the height of one end of the aluminum storage container connected to the public chute, when the aluminum liquid entering the aluminum storage container increases instantly, the aluminum liquid can automatically flow from the first diverter trough into the residual aluminum box, ensuring that the aluminum liquid flow entering the casting chute body is constant;

[0014] 2. By setting the size of the end of the aluminum storage container connected to the public chute to be smaller than the size of the end connected to the casting chute body, the flow rate of the aluminum liquid can be reduced, reducing the scouring of the inner wall of the aluminum storage container by the aluminum liquid after entering the aluminum storage container. The aluminum storage container extends from the public chute to the casting chute body. When the aluminum liquid flows through the aluminum storage container, due to the shape of the aluminum storage container and the friction between the aluminum liquid and the inner wall of the aluminum storage container, the aluminum liquid will be subjected to a centrifugal force toward the inner side of the aluminum storage container. This centrifugal force will cause the aluminum liquid to rotate or eddy in the aluminum storage container. However, due to the storage The constraint of the side wall of the aluminum container will suppress this rotation or eddy current tendency. However, when the aluminum liquid flows to the end where the aluminum storage container is connected to the casting chute body, the original force that constrains the flow of the aluminum liquid disappears due to the larger size of this place. At this time, the aluminum liquid will rotate here, causing the aluminum slag to float on the surface of the aluminum liquid under the action of the rotation force. When using it, first completely plug the plug into the flow hole. When the aluminum liquid level in the aluminum storage container rises, push the plug to make the aluminum liquid flow from the flow hole into the casting chute body, and the slag will remain in the aluminum storage container to ensure the purity of the aluminum liquid in the casting chute body.

[0015] 3. A casting spout is arranged on the casting chute body, and the casting spout is a trumpet-shaped structure expanding outward from the casting chute body, so that when the aluminum liquid flows in the casting spout, the more it flows forward, the shallower the depth, the slower the flow rate, and the smaller the scouring. The end of the casting spout away from the casting chute body is bent downward, which can reduce the height difference between the casting spout and the distributor at the end of the casting spout, reduce the scouring force, and finally achieve the purpose of slag reduction.

[0016] In summary, the utility model effectively solves the technical problems of the unstable aluminum liquid flow rate causing safety hazards and the large amount of slag in the aluminum ingot casting process in the prior art.

[0017] Furthermore, the casting spout is arranged on the adjacent side of the casting chute body which is connected to the aluminum storage container.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] It should be noted that the main concept of the automatic flow control low dross casting chute provided by the utility model is: by arranging a first diverter trough on the aluminum storage container, so that the height of the first diverter trough is lower than the height of the end of the aluminum storage container connected to the common chute, when the aluminum liquid flow rate increases instantaneously, the excess aluminum liquid can be discharged from the first diverter trough to the residual aluminum box to ensure that the aluminum liquid flow rate entering the casting chute body is constant; by arranging an aluminum storage container whose size gradually increases from the common chute to the casting chute body, and making the aluminum storage container bend and extend from the common chute to the casting chute body, the flow rate of the aluminum liquid when flowing in the aluminum storage container can be gradually reduced, The scouring of the inner wall of the aluminum storage container by the aluminum liquid is reduced, and the aluminum slag is floated on the surface of the aluminum liquid. When the plug is pulled out, the aluminum liquid flows into the casting chute body from the flow hole, and the slag remains in the aluminum storage container; by arranging a casting spout on the casting chute body, and designing the casting spout as a trumpet-shaped structure that expands outward from the casting chute body, when the aluminum liquid flows in the casting spout, the deeper it flows, the slower the flow rate, and the smaller the scouring. The end of the casting spout that is away from the casting chute body is bent downward, which can reduce the height difference between the casting spout and the distributor located at the end of the casting spout, reduce the scouring force, and achieve the purpose of reducing slag.

[0036] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0037] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0038] Embodiment 1 of the automatic flow control low slag casting chute provided by the utility model:

[0039] like Figures 1 to 4 As shown, the automatic flow-controlled low-slag casting chute includes a support frame 7, an aluminum storage container 2 and a casting chute body 1, wherein a first rotating assembly and a third rotating assembly are respectively installed at both ends of the top surface of the support frame 7, a third rotating assembly is arranged between the first rotating assembly and the second rotating assembly, and the third rotating assembly is installed on the side of the support frame 7, one end of the aluminum storage container 2 is connected to the first rotating assembly, and the other end is connected to the second rotating assembly, and one end of the casting chute body 1 is fixedly connected to the aluminum storage container 2, and the other end is connected to the third rotating assembly.

[0040] About the aluminum storage container 2. A flow hole 3 is provided on the left side of the aluminum storage container 2, and the right side is connected to the public chute. The end of the public chute connected to the aluminum storage container 2 is equipped with a front spout. The rear side of the aluminum storage container 2 is connected to the first diverter trough 5, and the tail of the first diverter trough 5 is connected to the residual aluminum box. The right section of the aluminum storage container 2 is an arc section, so that it bends and extends from the public chute to the casting chute body 1, and the size of the end connected to the public chute is smaller than the size of the end connected to the casting chute body 1.

[0041] Specifically, the center of the aluminum storage container 2 coincides with that of the common chute, that is, the end of the aluminum storage container 2 connected to the common chute is designed in a concentric circle manner, so that when the aluminum storage container 2 and the casting chute body 1 tip over in an emergency, they can rotate around the center of the front end spout as the center, so that the molten aluminum can flow directly into the residual aluminum box.

[0042] About the casting chute body 1. The casting chute body 1 is a ship-shaped chute, and a flow hole 3 matching the flow hole 3 of the aluminum storage container 2 is arranged on the right side thereof, and the two flow holes 3 are fixedly connected, and the flow hole 3 is equipped with a plug, which is pushed from the flow hole 3 of the aluminum storage container 2 into the flow hole 3 of the casting chute body 1 to block the flow hole 3. The casting chute body 1 is provided with a casting spout 4 on the front side and a second diversion trough 6 on the rear side, and the height of the second diversion trough 6 is lower than the height of the end of the aluminum storage container 2 connected to the public chute.

[0043] Specifically, the casting nozzle 4 is a trumpet-shaped structure that expands outward from the casting chute body 1, and its outer end is bent downward.

[0044] Specifically, a flow guide tube is embedded in the flow hole 3, such as Figure 5 As shown, the guide pipe includes a guide pipe body 16, which is a conical cylinder with a single-sided flange 17. When in use, the guide pipe is plugged into the flow hole 3, and the periphery is sealed with a heat-resistant material, and the guide pipe is blocked with a plug. When the plug is blocked for multiple times and causes the guide pipe to be damaged, the employee can take out the damaged guide pipe and replace it with a new one. The size of the flow hole 3 is designed according to the maximum production capacity of the equipment.

[0045] About the first rotating assembly. The first rotating assembly includes a base 10 installed on the top surface of the support frame 7, a curved plate 8 with the center facing upward is vertically arranged at the right end of the aluminum storage container 2, the top of the base 10 has a groove matching the curved plate 8, and a plurality of support rollers 11 are horizontally arranged in the groove.

[0046] About the second rotating assembly. The second rotating assembly is a cylinder 12, which is installed on the side of the support frame 7 away from the residual aluminum box. Two parallel connecting plates 9 are arranged at the bottom of the end where the aluminum storage container 2 is connected to the casting chute body 1. The output shaft of the cylinder 12 is fixedly connected to the connecting plate 9. The output shaft of the cylinder 12 drives the aluminum storage container 2 to rotate, thereby driving the casting chute body 1 to rotate.

[0047] About the third rotating assembly. The third rotating assembly includes a mounting seat 13 mounted on the top surface of the support frame 7, a bearing 14 is vertically mounted on the top of the mounting seat 13, and a connecting rod 15 matching the bearing 14 is horizontally arranged at one end of the casting chute body 1 away from the aluminum storage container 2, and the connecting rod 15 is inserted into the bearing 14 to ensure that the casting chute body 1 can rotate when the cylinder 12 drives the aluminum storage container 2 to rotate.

[0048] In addition, the plug is also connected to a servo motor, which drives the plug to move left and right in the flow hole 3 to control the size of the flow hole 3 between the aluminum storage container 2 and the casting chute body 1, thereby achieving control of the aluminum liquid flow rate.

[0049] The working principle of the automatic flow control low slag casting chute provided by the utility model is:

[0050] First, plug the plug into the flow hole 3, and discharge the aluminum liquid from the public chute into the aluminum storage container 2. After the aluminum liquid flows into the aluminum storage container 2, its speed gradually decreases as the size of the aluminum storage container 2 increases, which can reduce the scouring of the inner wall of the aluminum storage container 2. At the same time, the aluminum liquid will rotate along the arc of the aluminum storage container during its flow in the aluminum storage container, so that the slag will float on the surface of the aluminum liquid. After the liquid level of the aluminum liquid in the aluminum storage container 2 rises to a certain liquid level and is greater than the height of the flow hole 3, push the plug to make the aluminum liquid flow from the flow hole 3 into the casting chute body 1. The slag is left in the aluminum storage container 2. After the aluminum liquid enters the casting chute body 1, it flows from the casting nozzle 4 to the distributor. The flow rate of the aluminum liquid in the casting nozzle 4 gradually decreases as the width of the casting nozzle 4 increases, and the depth of the aluminum liquid also gradually becomes shallower as the width of the casting nozzle 4 increases. The scouring of the casting nozzle 4 by the aluminum liquid is getting smaller and smaller. At the same time, since the end of the casting nozzle 4 is bent downward, the height difference between it and the distributor is reduced, thereby reducing the scouring force of the aluminum liquid on the distributor, and finally achieving the purpose of reducing slag.

[0051] When the instantaneous flow of aluminum liquid in the common chute is too large, the amount of aluminum liquid entering the aluminum storage container 2 increases instantly, and the height of the first diversion trough 5 is lower than the height of the right end of the aluminum storage container 2. When the aluminum liquid flow exceeds the maximum production capacity of the equipment, the aluminum liquid will automatically flow from the first diversion trough 5 into the residual aluminum box to ensure that the aluminum liquid flow entering the casting chute body 1 is constant. At the same time, the plug can be moved by a servo motor or manually driven to control the size of the flow hole 3 between the aluminum storage container 2 and the casting chute body 1, thereby realizing the control of the aluminum liquid flow.

[0052] Based on the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as limitations on the solution of the present invention.

[0053] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
