Description

Technical Field

[0001] This invention relates to the field of metal material processing equipment, and in particular to a feeding buffer device and a smelting furnace. Background Technology

[0002] Smelting refers to the pyrometallurgical process of melting metal raw materials in a smelting furnace. Specifically, it involves a series of physical and chemical changes that occur in the metal material within the furnace, resulting in a molten metal solution. The molten metal obtained from heating and melting in the furnace can be poured out through the furnace's outlet for subsequent operations.

[0003] Because metal raw materials vary in size, they often bump into the smelting port during the feeding process, causing damage to the smelting furnace. Rebuilding the smelting furnace requires significant time and financial costs. Therefore, minimizing furnace damage during the feeding process has become a pressing issue. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a feeding buffer device that can protect the smelting furnace and reduce the occurrence of damage to the smelting furnace due to impacts with raw materials.

[0005] In a first aspect, embodiments of the present invention provide a feeding buffer device applied to a smelting furnace. The smelting furnace includes a smelting port, and the feeding buffer device includes a buffer baffle and a snap-fit ​​portion fixed to the inner sidewall of the smelting port. The buffer baffle is installed on the edge of the inner sidewall of the smelting port through the snap-fit ​​portion. The buffer baffle includes a fixing portion near the outer sidewall of the smelting port and a shock-absorbing portion near the center of the smelting port. An elastic buffer mechanism is provided between the fixing portion and the shock-absorbing portion.

[0006] The feeding buffer device provided by the present invention has at least the following beneficial effects: by setting a buffer baffle, the buffer baffle is installed on the edge of the inner wall of the melting port by means of a snap-fit ​​part fixed to the inner wall of the melting port, and the buffer baffle can be fixed to the melting furnace; since the buffer baffle is located above the inner wall of the melting port, the buffer baffle can completely cover the upper surface of the melting furnace, thereby avoiding direct collision between the raw material and the upper surface of the melting port, and reducing the occurrence of damage to the melting furnace due to the impact of the raw material. The buffer baffle also includes a fixing part near the outer side of the melting port and a shock-absorbing part near the center of the melting port. The fixing part is connected to the upper part of the snap-fit ​​part, allowing it to be fixedly installed on the inner edge of the melting port wall. The shock-absorbing part and an elastic buffer mechanism connecting the fixing part and the shock-absorbing part allow for adjustment of the shock-absorbing part's tilt angle. During the raw material's descent, the shock-absorbing part contacts the raw material first, effectively reducing the impact force when the raw material collides with the melting port, thus minimizing damage to the melting furnace due to impacts. Adjusting the tilt angle of the shock-absorbing part can also guide raw material that has fallen to an incorrect point, adjusting its landing position to prevent direct collision with the melting port. Therefore, this embodiment of the invention can protect the melting furnace and reduce damage caused by raw material impacts.

[0007] According to some embodiments of the present invention, the area of ​​the shock-absorbing part is larger than the area of ​​the fixing part.

[0008] According to some embodiments of the present invention, the feeding buffer device includes a fixed protective ring disposed along the inner sidewall of the melting port, the fixed protective ring abutting against the inner sidewall of the melting port, and the fixed protective ring extending from the melting port toward the interior of the melting furnace.

[0009] According to some embodiments of the present invention, the elastic buffer mechanism includes a support rod fixed to the fixed part and a buffer spring sleeved on the support rod, the buffer spring being connected to the shock-absorbing part.

[0010] According to some embodiments of the present invention, the support rod is a telescopic rod for adjusting the distance between the fixed part and the shock-absorbing part, and the support rod can extend or retract relative to the fixed part in the direction of the shock-absorbing part.

[0011] According to some embodiments of the present invention, the feeding buffer device further includes a frame, the frame being provided with a lifting device, the lifting device being connected to the buffer baffle to drive the buffer baffle to move up and down relative to the melting port.

[0012] According to some embodiments of the present invention, the fixing part is provided with a first slide rail, and the lifting device is connected to the fixing part through the first slide rail to drive the buffer baffle to move up and down.

[0013] According to some embodiments of the present invention, the feeding buffer device includes a plurality of buffer baffles and an annular slide rail corresponding to the edge of the melting port. The annular slide rail is fixed above the buckle portion, and the plurality of buffer baffles are slidably mounted on the annular slide rail.

[0014] According to some embodiments of the present invention, the feeding buffer device is provided with a sensor for determining the position of the raw material and a controller for controlling the movement of the buffer baffle. The controller is electrically connected to the buffer baffle and the sensor respectively, so as to control the movement of the buffer baffle according to the position of the raw material.

[0015] Secondly, embodiments of the present invention provide a smelting furnace, including a feeding buffer device as described in the first aspect of the embodiments above.

[0016] The smelting furnace provided according to embodiments of the present invention has at least the following beneficial effects: the smelting furnace includes the smelting furnace itself and a feeding buffer device disposed above the smelting port. The smelting furnace is mainly used for smelting metals. The smelting port includes a discharge port, through which molten metal can be poured out. The inner sidewall of the smelting port is also provided with an annular groove corresponding to the edge of the smelting port. The feeding buffer device includes a buffer baffle and a snap-fit ​​part. The snap-fit ​​part engages with the annular groove on the inner sidewall of the smelting port, thereby fixing the buffer baffle to the edge of the inner sidewall of the smelting port. The buffer baffle is located above the smelting port and can completely cover the upper surface of the smelting port to prevent the raw material from directly colliding with the upper surface of the smelting furnace during its fall, thus reducing the occurrence of damage to the smelting furnace due to impact from the raw material. In addition, the buffer baffle also includes a fixing part, a shock-absorbing part, and an elastic buffer mechanism. The elastic buffer mechanism connects the fixing part and the shock-absorbing part. The fixing part is fixed to the upper part of the inner wall of the melting port via a snap-fit ​​part. The shock-absorbing part is connected to the fixing part via the elastic buffer mechanism and can also be fixed to the upper part of the inner wall of the melting port. During the process of raw material falling into the melting furnace, the raw material will first contact the shock-absorbing part. The shock-absorbing part has a shock-absorbing and buffering effect, which can effectively reduce the impact force when the raw material collides with the melting port, reducing the occurrence of damage to the melting furnace due to collisions. At the same time, the shock-absorbing part can also guide the raw material that falls at the wrong point, adjust the landing position of the raw material, and avoid direct collision between the raw material and the melting port. Therefore, the embodiments of the present invention can protect the melting furnace and reduce the occurrence of damage to the melting furnace due to raw material collisions.

[0023] This invention provides a feeding buffer device and a smelting furnace. The feeding buffer device uses a buffer baffle, which is installed on the edge of the inner wall of the smelting port by means of a snap-fit ​​part fixed to the inner wall of the smelting port, thus fixing the buffer baffle to the smelting furnace. Since the buffer baffle is located above the inner wall of the smelting port, it can completely cover the upper surface of the smelting furnace, thereby preventing the raw materials from directly colliding with the upper surface of the smelting port and reducing the occurrence of damage to the smelting furnace due to impact.

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] A first aspect of the present invention provides a feeding buffer device applied to a smelting furnace 100. The smelting furnace 100 includes a smelting port 110. The feeding buffer device includes a buffer baffle 200 and a snap-fit ​​portion 300 fixed to the inner sidewall of the smelting port 110. The buffer baffle 200 is installed on the edge of the inner sidewall of the smelting port 110 through the snap-fit ​​portion 300. The buffer baffle 200 includes a fixing portion 210 near the outer sidewall of the smelting port 110 and a shock-absorbing portion 220 near the center of the smelting port 110. An elastic buffer mechanism 230 is provided between the fixing portion 210 and the shock-absorbing portion 220.

[0026] like Figure 1 As shown, it can be understood that the feeding buffer device of this embodiment is applied to the smelting furnace 100. The feeding buffer device, by setting a buffer baffle 200, uses a snap-fit ​​part 300 fixed to the inner sidewall of the smelting port 110 to install the buffer baffle 200 on the edge of the inner sidewall of the smelting port 110, thereby fixing the buffer baffle 200 to the smelting furnace 100. Specifically, the snap-fit ​​part 300 of this embodiment is a "concave" type snap-fit, with both the upper and lower parts of the snap-fit ​​part 300 being protruding structures. Since the inner sidewall of the smelting port 110 of the smelting furnace 100 is provided with an annular groove adapted to the smelting port 110, the protrusion of the lower part of the snap-fit ​​part 300 is snapped into the annular groove of the inner sidewall of the smelting port 110, thereby fixing the snap-fit ​​part 300 to the inner sidewall of the smelting furnace 100. Meanwhile, the bottom end of the buffer baffle 200 and the protruding structure on the upper part of the snap-fit ​​part 300 are fixedly connected by a flange, which enables the buffer baffle 200 to be fixedly installed on the inner side wall edge of the melting port 110.

[0027] It should be noted that the latching part 300 in this embodiment can be an elastic latch or other latching components with a fixing function, and no specific limitation is made here.

[0028] Understandably, the buffer baffle 200 is located above the melting port 110 and extends outward from the inner wall of the melting port 110. The area of ​​the buffer baffle 200 can completely cover the upper surface of the melting port 110, thereby preventing the raw material from directly colliding with the upper surface of the melting port 110 and reducing the possibility of damage to the melting furnace 100 due to impact from the raw material. For example, during the process of the raw material being fed into the melting furnace 100, since the buffer baffle 200 is located above the inner wall of the melting port 110, the raw material will first come into contact with the surface of the buffer baffle 200. The buffer baffle 200 buffers the raw material through the shock-absorbing part 220, which can effectively reduce the impact force when the raw material collides with the melting port 110, reduce the possibility of damage to the melting furnace 100 due to impact from the raw material, and allow the raw material to pass smoothly through the melting port 110 and fall into the melting furnace 100 for smelting.

[0029] Understandably, the buffer baffle 200 includes a fixing part 210 and a shock-absorbing part 220. The fixing part 210 is fixedly connected to one side of the upper part of the snap-fit ​​part 300 via a flange, thus connecting the fixing part 210 and the snap-fit ​​part 300. Since the other side of the upper part of the snap-fit ​​part 300 also abuts against the upper surface of the smelting furnace 100, placing the flange on the upper part of the snap-fit ​​part 300 and connecting it to the fixing part 210 provides support for the fixing part, allowing the buffer baffle 200 to be fixed to the inner wall of the smelting furnace 100. A shock-absorbing section 220 is provided, which has a buffering and shock-absorbing function to cushion the falling raw materials. Since the shock-absorbing section 220 is located above the inner wall of the melting port 110, it can completely cover the upper surface of the inner wall of the melting port 110, thereby preventing direct collision between the raw materials and the upper surface of the melting port 110 and reducing the possibility of damage to the melting furnace 100 due to impact. During the descent of raw materials with incorrect landing points, the shock-absorbing section 210, located above the side wall of the melting port 110, contacts the shock-absorbing section 210 first. The shock-absorbing section 210 effectively reduces the impact force when the raw materials collide with the melting port 110, reducing the possibility of damage to the melting furnace 100 due to impact. Simultaneously, the shock-absorbing section 220 can guide the falling raw materials with incorrect landing points, adjusting their landing position to prevent direct collision with the melting port 110.

[0030] It should be noted that the fixing part 210 of the buffer baffle 200 can be a rigid steel structure. The upper part of the snap-fit ​​part 300 is connected to the bottom end of the fixing part 210 via a flange. Since the lower part of the snap-fit ​​part 300 is fixed in the groove on the inner sidewall edge of the melting port 110, the fixing part 210, fixedly connected to the upper part of the snap-fit ​​part 300 via the flange, can also be fixed above the inner sidewall of the melting port 110. The fixing part 210 positions the buffer baffle 200 above the melting port 110, allowing the buffer baffle 200 to completely cover the upper surface of the melting port 110, preventing direct collision between the raw material and the upper surface of the melting furnace 100, and reducing damage to the melting port 110 caused by impact. The flange connects the fixing part 210 and the snap-fit ​​part 300, allowing the buffer baffle 200 to be installed on the inner sidewall of the melting furnace 100, thereby improving the stability of the buffer baffle 200. Alternatively, the fixing part 210 and the snap-fit ​​part 300 can be integrated into one unit, which can improve the sturdiness of the buffer baffle 200.

[0031] Understandably, the buffer baffle 200 is also equipped with an elastic buffer mechanism 230. One end of the elastic buffer mechanism 230 is connected to the fixed part 210, and the other end is connected to the shock-absorbing part 220, which can connect the fixed part 210 and the shock-absorbing part 220 to form a buffer baffle 200 with a buffering function. During the falling process of the raw material, the raw material will first come into contact with the shock-absorbing part 220 of the buffer baffle 200. The elastic buffer mechanism 230 can adjust the tilt angle of the shock-absorbing part 220 according to the landing position of the raw material on the shock-absorbing part 220, so that the distance between the top, bottom, left or right side of the shock-absorbing part 230 and the fixed part 210 is reduced, that is, the tilt angle of the shock-absorbing part 220 is readjusted, so that the shock-absorbing part 220 can guide the raw material that has fallen at the wrong point to fall, thereby avoiding direct collision between the raw material and the melting port 110, and reducing the occurrence of damage to the melting port 110 due to the impact of the raw material.

[0032] It should be noted that the melting port 110 of the melting furnace 100 in this embodiment includes a discharge port. The melting furnace 100 is used to melt metal raw materials, while the discharge port is used to pour out the molten metal. A buffer baffle 200 is provided, which can completely cover the upper surface of the melting furnace 100. This not only prevents the raw materials from directly colliding with the upper surface of the melting port 110, but also prevents the raw materials from directly colliding with the discharge port, thus reducing the occurrence of damage to the discharge port of the melting furnace 100 due to impacts from the raw materials.

[0033] It should be noted that the size, position, and shape of the buffer baffle 200 in this embodiment can be adjusted according to actual conditions. The buffer baffle 200 can be set on one side of the melting port 110 or it can be set around the entire melting port 110; and the structure of the buffer baffle 200 can be an arc-shaped plate structure or a vertical plate structure, which is not specifically limited here.

[0034] According to some embodiments of the present invention, the area of ​​the shock-absorbing part 220 is larger than the area of ​​the fixing part 210.

[0035] Understandably, the shock-absorbing part 220 of the buffer baffle 200 has a buffering and shock-absorbing function. The area of ​​the shock-absorbing part 220 is larger than the area of ​​the fixed part 210, which expands the range of the shock-absorbing part 220 covering the upper surface of the melting port 110, thereby increasing the protective area of ​​the shock-absorbing part 220 on the melting furnace 100. Simultaneously, the increased area of ​​the shock-absorbing part 220 also increases the contact area between the input raw material and the shock-absorbing part 220. Since the shock-absorbing part 220 has a buffering and shock-absorbing function, the increased area of ​​the shock-absorbing part 220 can effectively reduce the impact force when the raw material collides with the melting port 110, thereby improving the buffering effect of the buffer baffle 200 and reducing the occurrence of damage to the melting port 110 due to impacts from raw materials.

[0036] It should be noted that the shock-absorbing part 220 can be made of rubber or other raw materials with cushioning and shock-absorbing effects, and no specific limitation is made here.

[0037] According to some embodiments of the present invention, the feeding buffer device includes a fixed protective ring disposed along the inner sidewall of the melting port 110, the fixed protective ring abutting against the inner sidewall of the melting port 110, and the fixed protective ring extending from the melting port 110 toward the interior of the melting furnace 100.

[0038] It is understood that the feeding buffer device in this embodiment is also provided with a fixed protective ring along the inner wall of the melting port 110. The fixed protective ring is in close contact with the inner wall of the melting port 110 and extends from the melting port 110 toward the interior of the melting furnace 100. It can completely cover the edge of the inner wall of the melting port 110 and reduce the damage to the inner wall of the melting port 110 caused by the impact of raw materials.

[0039] It should be noted that the recessed structure in the middle of the snap-fit ​​portion 300 in this embodiment abuts against the fixed protective ring. In addition to the fixed protective ring, this embodiment also includes a buffer baffle 200. The fixing portion 210 of the buffer baffle 200 is positioned above the fixed protective ring, and the area of ​​the shock-absorbing portion 220 is larger than the area of ​​the fixing portion 210. Since the fixed protective ring abuts against the inner wall of the melting port 110, and the fixing portion 210 of the buffer baffle 200 is positioned above the fixed protective ring, this is equivalent to the fixing portion 210 being positioned above the inner wall of the melting port 110. The buffer baffle 200 is located above the inner wall of the melting port 110, completely shielding the upper surface of the melting port 110. Utilizing the damping effect of the shock-absorbing part 220, direct collision between the raw material and the upper surface of the melting furnace 100 is prevented. Simultaneously, the fixed protective ring abuts against the inner wall of the melting port 110, protecting the edge of the inner wall. In other words, by simultaneously providing the buffer baffle 200 and the fixed protective ring, both the upper surface and the edge of the inner wall of the melting port 110 are protected, reducing damage to the melting furnace 100 caused by impacts from raw materials. Furthermore, the area of ​​the shock-absorbing part 220 is larger than that of the fixed part 210, effectively increasing the protected area of ​​the melting furnace 100.

[0040] According to some embodiments of the present invention, the elastic buffer mechanism 230 includes a support rod fixed to the fixing part 210 and a buffer spring sleeved on the support rod, the buffer spring being connected to the shock-absorbing part 220.

[0041] It is understood that the elastic buffer mechanism 230 of this embodiment is provided with a support rod and a buffer spring sleeved on the support rod. The support rod and the buffer spring can connect the fixing part 210 and the shock-absorbing part 220 to form the buffer baffle 200 of the feeding buffer device. By providing the buffer spring, during the falling process of raw materials with incorrect landing points, since the shock-absorbing part 220 is located above the inner wall of the melting port 110, the raw materials will first contact the shock-absorbing part 220. At this time, the shock-absorbing part 220 is connected to the buffer spring, and the elasticity of the buffer spring can readjust the landing point of the raw materials, reducing the damage to the melting port 110 caused by the impact of the raw materials. For example, taking the melting port 110 as a reference, the side of the damping part 220 that is close to the melting port 110 is the lower end of the damping part 220, and the side that is away from the melting port 110 is the upper end of the damping part 220. When the landing point of the raw material is located at the upper end of the damping part 220, the buffer spring can retract relative to the damping part 220 towards the fixing part 210 to adjust the tilt angle of the damping part 220, thereby guiding the raw material to fall and avoiding direct collision between the raw material and the melting port 110, reducing the occurrence of damage to the melting port 110 due to the impact of the raw material.

[0042] According to some embodiments of the present invention, the support rod is a telescopic rod for adjusting the distance between the fixing part 210 and the damping part 220, and the support rod can extend or retract relative to the fixing part 210 toward the damping part 220.

[0043] It is understood that the support rod fixed to the fixing part 210 in this embodiment is a telescopic rod. The telescopic nature of the rod allows adjustment of the distance between the top, bottom, left, and right sides of the shock-absorbing part 220 and the fixing part 210, creating different inclination angles. The support rod's extension and retraction are adjusted according to the weight and volume of the raw material, facilitating the smooth passage of the raw material through the melting port 110 under the buffering effect of the buffer baffle 200. Specifically, if the volume of the input raw material is too large, the telescopic rod can retract relative to the shock-absorbing part 220 towards the fixing part 210 to form an opening that matches the size of the raw material. This allows the raw material to pass smoothly through the melting port 110 and fall into the smelting furnace 100 for smelting, preventing direct collisions between the raw material and the melting port 110 and reducing the risk of damage to the melting port 110 due to impacts.

[0044] It should be noted that the bottom end of the fixing part 210 of the buffer baffle 200 and the bottom end of the shock-absorbing part 220 can also be connected by a coupling. The coupling can adjust the angle between the fixing part 210 and the shock-absorbing part 220, thereby adjusting the tilt of the shock-absorbing part 220. This can guide the raw material to fall and prevent the raw material from colliding directly with the melting port 110, reducing the occurrence of damage to the melting port 110 due to the impact of the raw material.

[0045] According to some embodiments of the present invention, the feeding buffer device further includes a frame, the frame being provided with a lifting device, the lifting device being connected to the buffer baffle 200 to drive the buffer baffle 200 to move up and down relative to the melting port 110.

[0046] It should be noted that the buffer baffle 200 in this embodiment is a detachable structure, equipped with a frame and a lifting device. Connecting the lifting device to the buffer baffle 200 allows it to move up and down relative to the melting port 110. Since the melting port 110 also includes a discharge port for pouring out the raw material solution, if the buffer baffle 200 is positioned above the discharge port, it would be inconvenient for the melting furnace 100 to perform the discharge operation. By providing the lifting device, during the discharge process from the melting furnace 100, the buffer baffle 200 can be raised relative to the melting port 110 through external operation, facilitating the pouring out of the molten metal from the discharge port. This prevents the buffer baffle 200 from being damaged by impact or burned by high temperatures during the pouring process.

[0047] According to some embodiments of the present invention, the fixing part 210 is provided with a first slide rail, and the lifting device is connected to the fixing part 210 through the first slide rail to drive the buffer baffle 200 to move up and down.

[0048] It should be noted that the latching part 300 in this embodiment is equipped with a trigger button. When the buffer baffle 200 needs to be raised or lowered, the lower protruding structure of the latching part 300 can be popped out of the groove on the inner sidewall of the melting port 110 by triggering the button. When the latching part 300 pops out of the groove on the inner sidewall of the melting port 110, the fixing part 210 of the buffer baffle 200 can move up and down relative to the inner sidewall of the melting port 110. The bottom surface of the fixing part 210 is provided with a first slide rail, which is arranged in the vertical direction. The lifting device is connected to the fixing part 210 through the first slide rail, which can raise the fixing part 210 relative to the melting port 110, which is beneficial for timely adjustment of the position of the buffer baffle 200. When the buffer baffle 200 is not needed, the buffer baffle 200 can be raised by means of the lifting device and the first slide rail, so that the melting furnace 100 can perform other subsequent operations. For example, during the discharge process of the smelting furnace 100, the buffer baffle 200 may obstruct the pouring of the solution from the discharge port. By operating the lifting device, the buffer baffle 200 can be moved upwards along the first slide rail, removing it from above the smelting port 110 and thus preventing it from obstructing the discharge of the smelting furnace 100. Furthermore, removing the buffer baffle 200 also prevents it from being damaged by impact or burned by high temperatures during the discharge process.

[0049] According to some embodiments of the present invention, the feeding buffer device includes a plurality of buffer baffles 200 and an annular slide rail corresponding to the edge of the melting port 110. The annular slide rail is fixed above the buckle part 300, and the plurality of buffer baffles 200 are slidably installed on the annular slide rail.

[0050] It should be noted that the feeding buffer device in this embodiment also includes an annular slide rail fixed above the snap-fit ​​part 300. The annular slide rail corresponds to the edge of the melting port 110 and is arranged around the melting port 110 of the smelting furnace 100. Multiple buffer baffles 200 slidably mounted on the annular slide rail can slide relative to each other to form a feeding buffer device around the melting port 110. When an automatic feeding track is provided, the multiple buffer baffles 200 can slide relative to each other from one side of the automatic feeding track to the other side of the automatic feeding track to form a feeding buffer device around the outlet of the automatic feeding track. When the raw material is fed from the automatic feeding track, the buffer baffles 200 can prevent the raw material from directly colliding with the melting port 110, reducing the possibility of damage to the smelting furnace 100 caused by the impact of the raw material on the melting port 110 during its descent.

[0051] It should be noted that during the process of feeding raw materials into the smelting furnace 100, the buffer baffle 200 can be controlled to slide in the annular slide rail according to the position of the raw materials, so that the position of the buffer baffle 200 can be adjusted. With the help of the buffer baffle 200, the raw materials can be prevented from directly colliding with the smelting port 110, reducing the occurrence of damage to the smelting port 110 due to the impact of the raw materials.

[0052] It should be noted that, in another embodiment of the present invention, the feeding buffer device may simultaneously include an annular slide rail, a lifting device, a first slide rail, and a buffer baffle 200. Firstly, the buffer baffle 200 can slide relative to the raw material in the annular slide rail according to the position of the raw material input, thereby forming a complete feeding buffer device. The structure formed by multiple buffer baffles 200 is located above the inner wall of the melting port 110, completely blocking the upper surface of the melting port 110, thus preventing direct collision between the raw material and the melting port 110 and reducing damage to the melting port 110 caused by impact. After the buffer baffles 200 are adjusted in position via the annular slide rail, when discharge is required, the multiple buffer baffles 200 can be moved upwards using the lifting device and the first slide rail, allowing the molten metal to be smoothly poured out of the melting port 110, preventing collision damage or high-temperature burning of the buffer baffles 200 during the discharge process from the melting furnace 100.

[0053] According to some embodiments of the present invention, the feeding buffer device is provided with a sensor for determining the position of the raw material and a controller for controlling the movement of the buffer baffle 200. The controller is electrically connected to the buffer baffle 200 and the sensor respectively, so as to control the movement of the buffer baffle 200 according to the position of the raw material.

[0054] It should be noted that the sensor in this embodiment can be an infrared sensor, a magnetic sensor, or other imaging device, and is not specifically limited here. Furthermore, the sensor in this embodiment can be disposed on one side of the smelting furnace 100 or above the smelting furnace 100, and is not specifically limited here either.

[0055] Understandably, after the position of the raw material is determined by the sensor, the controller can move the buffer baffle 200 according to the position of the raw material. Specifically, the sensor can acquire the position of the raw material in real time. When the sensor detects that the raw material is being fed from one side of the smelting furnace 100, the controller can control the buffer baffle 200 to slide to the side opposite to the feeding side for buffering. When the sensor detects that the raw material is being fed from above the smelting furnace 100, the controller can control multiple buffer baffles 200 to slide relative to each other, forming a buffer ring around the smelting opening 110 to buffer the raw material. The structure formed by the buffer baffle 220 can completely block the area above the smelting opening 110, thereby preventing direct collision between the raw material and the smelting opening 110 during its descent, reducing the possibility of damage to the smelting opening 110 due to impact, and thus extending the service life of the smelting furnace 100.

[0056] A second aspect of the present invention provides a smelting furnace 100, including a feeding buffer device as described in the first aspect of the present invention.

[0057] Understandably, the smelting furnace 100 includes the furnace itself and a feeding buffer device positioned above the smelting port 110. The smelting furnace 100 is mainly used for smelting metal. The smelting port 110 includes a discharge port, through which molten metal can be poured out. The inner wall of the smelting port 110 is also provided with an annular groove corresponding to the edge of the smelting port 110. The feeding buffer device includes a buffer baffle 200 and a snap-fit ​​part 300. The snap-fit ​​part 300 engages with the annular groove on the inner wall of the smelting port 110, fixing the buffer baffle 200 to the edge of the inner wall of the smelting port 110. The buffer baffle 200 is located above the smelting port 110 and can completely cover the upper surface of the smelting port 110 to prevent the raw material from directly colliding with the surface of the smelting furnace 100 during its descent, thereby reducing the possibility of damage to the smelting furnace 100 due to impact from the raw material. In addition, the buffer baffle 200 also includes a fixing part 210, a shock-absorbing part 220, and an elastic buffer mechanism 230. The elastic buffer mechanism 230 connects the fixing part 210 and the shock-absorbing part 220. The fixing part 210 is fixed to the upper part of the inner wall of the melting port 110 through the snap-fit ​​part 300. The shock-absorbing part 220 is connected to the fixing part 210 through the elastic buffer mechanism 230. The shock-absorbing part 220 can also be fixed to the upper part of the inner wall of the melting port 110. During the process of the raw material falling into the melting furnace 100, the raw material will first come into contact with the shock-absorbing part 220. The shock-absorbing part 220 has a shock-absorbing and buffering effect, which can effectively reduce the impact force when the raw material collides with the melting port 110, and reduce the occurrence of damage to the melting furnace 100 due to collision. At the same time, the shock-absorbing part 220 can guide the raw material that falls at the wrong point, adjust the landing position of the raw material, and avoid direct collision between the raw material and the melting port 110. Therefore, the embodiments of the present invention can protect the smelting furnace and reduce the occurrence of damage to the smelting furnace due to impacts with raw materials.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
