Description

Technical Field

[0001] This utility model relates to the field of crucible technology, and more specifically, to a non-stick, easy-to-demold crucible for a high-purity copper smelting furnace. Background Technology

[0002] Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, they have a small coefficient of thermal expansion, a certain resistance to rapid heating and cooling, strong resistance to corrosion by acid and alkaline solutions, and excellent chemical stability.

[0003] The production of graphite crucibles involves adding raw materials into a mold to form the crucible, and then removing it after it has been shaped. However, since graphite crucibles are generally formed inside the mold, removing them from the mold is very troublesome. Patent CN215511595U proposes a high-temperature molten salt erosion resistant and easy-to-demold graphite crucible. In this patent, a cylinder pushes a receiving block, which in turn pushes a rod via a shaft. The rod moves a sliding plate via a hinge seat. The sliding plate moves linearly under the action of the sliding rod and the vertical bearing until the pressure plate presses against the inner wall of the graphite crucible. The pressure plate then moves linearly backward under the action of the guide post and the vertical bearing, compressing the spring. Under the rebound force of the spring, the fixing device is fixed inside the graphite crucible, making it easy to pull the graphite crucible out of the mold cavity.

[0004] However, when the pressure plate squeezes the inner wall of the graphite crucible, the pressure plate directly contacts and squeezes the inner wall of the graphite crucible. During the squeezing process, it is easy to cause mechanical damage to the inner wall of the crucible, resulting in scratches or local deformation, which affects the surface quality and service life of the crucible. In addition, when the pressure plate squeezes the inner wall of the crucible, it will apply a large lateral force to the crucible. Especially during the demolding process, when it is necessary to overcome a certain friction and adhesion force, excessive squeezing force may cause the crucible to deform. Utility Model Content

[0005] To solve at least one of the above problems, the present invention first provides a non-stick, easy-to-demold crucible for a high-purity copper smelting furnace, comprising a crucible forming mold and a crucible body. A support frame is installed on the upper side wall of the crucible forming mold, a pushing cylinder is installed on the upper side wall of the support frame, a connecting plate is fixedly connected to the output end of the pushing cylinder, a connecting pad is fixedly connected to the lower side wall of the connecting plate, and a fixing plate is installed on the lower side wall of the connecting pad.

[0006] The lower side wall of the fixed plate is fixedly connected to several connecting branch pipes, and the lower end of each connecting branch pipe is fixedly connected to a connecting suction cup. The upper side wall of each connecting suction cup is fixedly connected to a venting component. A negative pressure pump is installed on the lower side wall of the fixed plate. The crucible body is set in a crucible forming mold, and the interior of the crucible body is provided with a threaded groove.

[0007] Optionally, the diameter of the crucible body gradually decreases from top to bottom, so that the crucible body is provided with a draft angle, making it easy to demold the crucible body from the crucible forming mold.

[0008] Optionally, the suction end of the negative pressure pump is fixedly connected to a negative pressure connecting pipe, which is connected to the connecting suction cup via a connecting branch pipe. The negative pressure pump can extract the gas between the connecting suction cup and the lower inner wall of the crucible body through the negative pressure connecting pipe and the connecting branch pipe, thereby improving the connection strength between the connecting suction cup and the crucible body.

[0009] Optionally, the connecting pad is made of silicone material, which gives the connecting pad a cushioning effect.

[0010] Optionally, a connecting iron block is slidably connected inside the venting assembly, and a sealing gasket is installed on the outer side wall of the connecting iron block near the lower side to improve the sealing between the connecting iron block and the venting assembly.

[0011] Optionally, the top of the venting component is provided as an electromagnet block, and a connecting spring is fixedly connected to the lower side wall of the electromagnet block. When the electromagnet block is energized, it will attract the connecting iron block, thereby causing the connecting iron block to move to the upper side of the vent.

[0012] Optionally, the outer wall of the venting component is provided with an vent hole. When the iron block moves to the upper side of the vent hole, outside air enters the connecting suction cup through the vent hole, thereby separating the connecting suction cup from the crucible body.

[0013] Optionally, the lower inner wall of the crucible body is configured as a planar structure, and the crucible body cooperates with the connecting suction cup to improve the connection effect between the connecting suction cup and the crucible body.

[0014] Compared to existing technologies, the non-stick, easy-to-demold crucible for high-purity copper smelting furnace in this invention, through the cooperation of a negative pressure pump, connecting suction cups, and venting components, can easily achieve rapid separation of the crucible body from the molding die. During demolding, the negative pressure pump draws gas between the connecting suction cups and the lower inner wall of the crucible to form a negative pressure that adsorbs and fixes the crucible. During demolding, the electromagnet is energized to attract the connecting iron block, allowing outside air to enter through the vent hole to break the negative pressure, achieving rapid demolding, significantly improving demolding efficiency, reducing manual operation, and increasing the degree of production automation. The inner wall of the crucible body is provided with a threaded groove, which can interfere with the flow of molten metal, causing the molten metal to form local eddies or turbulence during the flow process. This reduces the static contact time between the molten metal and the crucible wall, reduces the possibility of excessive cooling and adhesion of the molten metal in local areas, helps to keep the crucible clean, and improves smelting efficiency and quality.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0023] This utility model embodiment provides a non-stick, easy-to-demold crucible for a high-purity copper smelting furnace. The crucible forming mold 1 is the basic component of the entire device, used to support and bear the crucible body 7, ensuring the stability and safety of the crucible during forming and use. Figure 1 As shown, the crucible forming mold 1 has a cylindrical structure with a hollow interior for accommodating the crucible body 7. In this embodiment, the crucible forming mold 1 is made of high-strength refractory material, which has good high-temperature resistance and mechanical strength, and can withstand the thermal and mechanical stresses during the high-temperature melting process.

[0024] The support frame 2 is installed on the upper side wall of the crucible forming mold 1 to support the push cylinder 3 and other related components, such as... Figure 1As shown, the support frame 2 is a metal frame structure, and its upper side wall is connected to the output end of the push cylinder 3. The support frame 2 is made of metal material to ensure sufficient strength and stability in high temperature environment, and can reliably support the weight of the push cylinder 3 and other components.

[0025] The push cylinder 3 is mounted on the upper side wall of the support frame 2 to provide a downward pushing force, driving the connecting plate 31 and subsequent components to move downwards, such as... Figure 1 As shown, the output end of the pushing cylinder 3 is fixedly connected to the connecting plate 31. In this embodiment, the pushing cylinder 3 is a high-temperature cylinder, which can work stably in a high-temperature environment to ensure the reliability and accuracy of the pushing process. The stroke and thrust of the pushing cylinder 3 can be adjusted according to actual needs to adapt to crucible bodies 7 of different sizes and weights.

[0026] The connecting plate 31 is fixedly connected to the output end of the pushing cylinder 3, and is used to transmit the pushing force of the pushing cylinder 3 to the connecting pad 32, such as... Figure 1 As shown, the connecting plate 31 has a circular plate structure, and its lower sidewall is fixedly connected to the connecting pad 32. The connecting plate 31 is made of high-strength metal material to ensure that it will not deform or be damaged when transmitting driving force.

[0027] The connecting pad 32 is made of silicone material and is fixedly connected to the lower side wall of the connecting plate 31, such as... Figure 2 As shown, the connecting pad 32 has a circular plate structure, and its lower sidewall is connected to the fixed plate 33. The silicone material has good elasticity and cushioning performance, which can provide a certain cushioning effect on the fixed plate 33 and subsequent components when the cylinder 3 is pushed down, reducing the impact of the impact force on the crucible body 7 and effectively protecting the surface quality and structural integrity of the crucible body 7.

[0028] The fixing plate 33 is installed on the lower side wall of the connecting pad 32 and is used to fix the connecting branch pipe 52 and other related components, such as... Figure 2 As shown, the fixed plate 33 has a circular plate structure, and its center is connected to the connecting pad 32. The fixed plate 33 is made of metal material, which has good strength and rigidity, and can stably support the weight of the connecting branch pipe 52 and other components, and ensure that the entire device can move downward smoothly under the action of the pushing cylinder 3.

[0029] The negative pressure pump 5 is installed on the lower side wall of the fixed plate 33 to generate negative pressure and extract the gas between the suction cup 4 and the lower inner wall of the crucible body 7. Figure 3The suction end of the negative pressure pump 5 is fixedly connected to a negative pressure connecting pipe 51. The negative pressure connecting pipe 51 is connected to the connecting suction cup 4 through a connecting branch pipe 52. In this embodiment, the negative pressure pump 5 adopts a high-efficiency vacuum pump, which can generate sufficient negative pressure in a short time to ensure the connection strength between the connecting suction cup 4 and the crucible body 7. The start and stop of the negative pressure pump 5 can be controlled by the control system to realize an automated operation process.

[0030] One end of the connecting branch pipe 52 is fixedly connected to the lower side wall of the fixed plate 33, and the other end is connected to the connecting suction cup 4, such as... Figure 3 As shown, each connecting branch pipe 52 is connected to the negative pressure connecting pipe 51, transmitting the negative pressure generated by the negative pressure pump 5 to the connecting suction cup 4. The connecting branch pipe 52 is made of high temperature and wear resistant material to ensure stable transmission of negative pressure in high temperature environment, and will not leak or be damaged due to thermal expansion or mechanical stress.

[0031] The connecting suction cup 4 is fixedly connected to the lower end of the connecting branch pipe 52, and is used to cooperate with the lower inner wall of the crucible body 7 to achieve the fixation and demolding of the crucible body 7. Figure 3 As shown, the connecting suction cup 4 has a circular suction cup structure. Its upper sidewall is connected to the connecting branch pipe 52, and its lower sidewall is in contact with the lower inner wall of the crucible body 7. The connecting suction cup 4 is made of high temperature resistant and wear resistant rubber material, which has good sealing performance and adsorption capacity. Under negative pressure, it can be tightly attached to the lower inner wall of the crucible body 7, providing stable adsorption force and ensuring that the crucible body 7 will not be displaced or loosened during demolding.

[0032] The venting component 6 is installed on the upper side wall of the connecting suction cup 4 to control the air pressure balance between the connecting suction cup 4 and the crucible body 7, thereby achieving rapid demolding of the crucible body 7. Figure 4 As shown, the venting component 6 includes an electromagnet block 61, a connecting spring 62, a connecting iron block 63, a sealing gasket 64, and a vent hole 65. When demolding is required, the electromagnet block 61 is energized, attracting the connecting iron block 63, causing the connecting iron block 63 to move to the upper side of the vent hole 65. Outside air enters between the connecting suction cup 4 and the crucible body 7 through the vent hole 65, breaking the negative pressure and achieving rapid demolding. The venting component 6 has a reasonable structural design, sensitive and reliable operation, and can complete the venting operation in a short time, improving demolding efficiency.

[0033] The crucible body 7 is set in the crucible forming mold 1 and is used to contain and melt high-purity copper materials, such as... Figure 3As shown, the interior of the crucible body 7 is provided with a threaded inner groove 71. When the molten metal flows in the crucible, the groove will interfere with the flow of the molten metal, causing it to form local eddies or turbulence. This change in flow state can reduce the static contact time between the molten metal and the crucible wall, preventing the molten metal from being overcooled and adhering in local areas. The diameter of the crucible body 7 gradually decreases from top to bottom, forming a draft angle, which facilitates demolding from the crucible forming mold 1. The crucible body 7 is made of high-quality graphite material, which has good thermal conductivity, high temperature resistance and chemical stability, and can meet the process requirements of high-purity copper smelting.
