Description

Technical Field

[0001] This invention relates to the field of industrial kilns, specifically to a vacuum furnace feeding and discharging device, system, and method. Background Technology

[0002] In common industrial kilns, air and other gases are typically removed from the material before it is conveyed to the heating furnace. This process is to prevent air-laden material from entering the furnace. Therefore, a vacuum furnace is usually installed upstream of the heating furnace to evacuate the material.

[0003] Conventional methods for feeding materials into a vacuum furnace for vacuuming and transferring the materials, after the air and other gases have been removed from the vacuum furnace, to a heating furnace suffer from problems such as low transfer efficiency, time and labor costs, and heat loss within the heating furnace.

[0004] In addition, traditional kiln feeding methods generally use roller conveyors to improve feeding efficiency, but this method has the following disadvantages:

[0005] 1) The line contact between the sagger and the roller for loading materials results in insufficient friction, which causes the material to remain in an uncontrollable position during transportation due to inertia. This indirectly limits the size of the sagger for loading materials and requires a larger safety holding space to reduce equipment failure.

[0006] 2) Since the sagger cannot be designed to be too large, the output of the equipment is limited to a certain extent while meeting the process requirements. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a vacuum furnace feeding and discharging device, system and method that can continuously vacuum materials and transport them into the heating furnace under sealed conditions.

[0008] This invention provides a vacuum furnace feeding and discharging device, including a bracket, a support platform movable along the X direction on the bracket, and a material feeding assembly and a material ejection assembly arranged side by side along the X direction on the support platform;

[0009] The material feeding assembly includes a material support platform mounted on a support platform and a material pusher that can move along the Y direction on the material support platform;

[0010] The material ejection assembly includes a second Y-direction drive component mounted on a support platform and an ejection rod mounted on the output end of the second Y-direction drive component. The first vacuum furnace door is mounted on the support platform, and a sliding hole is provided on the first vacuum furnace door. The ejection rod is slidably mounted on the sliding hole.

[0011] Furthermore, the ejector rod and the sliding hole are in a sliding sealing fit.

[0012] Furthermore, the sliding hole is located below the connection point between the first vacuum furnace door and the output end of the first Y-direction drive component.

[0013] Furthermore, the vacuum furnace feeding and discharging device also includes a first Y-direction drive unit mounted on the support platform, and the first vacuum furnace door is mounted on the output end of the first Y-direction drive unit.

[0014] Furthermore, the material feeding component includes a third Y-direction drive component disposed on the support platform and a feeding component disposed on the output end of the third Y-direction drive component.

[0015] Furthermore, the material support platform is equipped with a chute arranged along the Y direction;

[0016] The third Y-direction drive unit is located below the material carrier platform. The top-entry unit is connected to the output end of the third Y-direction drive unit through a vertical connecting plate, which is slidably positioned within the chute.

[0017] The present invention also provides a vacuum furnace feeding and discharging system, including a vacuum furnace body, a feeding device, and the aforementioned vacuum furnace feeding and discharging device;

[0018] The feeding device is used to supply materials to the material support platform;

[0019] The end of the vacuum furnace body away from the first vacuum furnace door is used to connect a sealing or high-pressure device, and a second vacuum furnace door is provided between the sealing or high-pressure device and the vacuum furnace body.

[0020] Furthermore, the feeding device includes a conveying roller mechanism and a pushing mechanism disposed on the conveying roller mechanism.

[0021] Furthermore, the vacuum furnace body has a cylindrical structure, and a moving platform is installed inside the vacuum furnace body.

[0022] The present invention also provides a method for feeding and discharging materials into a vacuum furnace, using the above-mentioned vacuum furnace feeding and discharging device, comprising the following steps:

[0023] S1. Control the second vacuum furnace door to be closed;

[0024] S2. The support platform is located in the first position of the bracket, and the feeding device conveys the material to the material support platform.

[0025] S3. Move the support platform to the second position of the bracket, while the first vacuum furnace door leaves the first opening of the vacuum furnace body, and the material carrier platform is aligned with the first opening of the vacuum furnace body. Drive the pusher to push the material into the vacuum furnace body through the third Y-direction drive.

[0026] S4. Move the support platform to the first position of the bracket, and the furnace door opening and closing mechanism closes the first vacuum furnace door along the Y direction;

[0027] S5. Vacuum the furnace body; after the vacuum furnace body reaches the specified vacuum level, introduce protective gas into the vacuum furnace body. After the protective gas reaches the set pressure, open the second vacuum furnace door and drive the ejector rod through the second Y-direction drive to eject the material from the second opening of the first vacuum furnace door.

[0028] Repeat steps S1-S5 to achieve material feeding and discharging and material vacuuming in the continuous vacuum furnace.

[0029] The beneficial effects of this invention are:

[0030] Firstly, the feeding of materials, the opening of the first vacuum furnace door, the removal of the first vacuum furnace door to expose the opening of the vacuum furnace body, and the alignment of the material with the opening of the vacuum furnace body can all be carried out simultaneously, improving the efficiency of material feeding and discharging. Furthermore, materials can be pushed out of the vacuum furnace body from an opening on the other side of the vacuum furnace body while the first vacuum furnace door is closed. When the vacuum furnace body is connected to the heating furnace, and a second vacuum furnace door is installed between the heating furnace and the vacuum furnace body, materials that have been de-aired and have had other gases removed can be transported from the vacuum furnace body to the heating furnace while the heating furnace is sealed, ensuring the sealing effect of the heating furnace at all times. This avoids heat waste in the heating furnace and saves energy.

[0031] Secondly, the ejector rod and the sliding hole on the first vacuum furnace door slide together. On the one hand, this allows the ejector rod and the first vacuum furnace door to move synchronously in the X direction, maintaining their relative positions. On the other hand, the sliding hole also serves as an intermediate support structure for the ejector rod, transforming the originally cantilevered ejector rod into a two-point support structure. During the ejection operation, this changes to a three-point support structure where the end of the ejector rod abuts against the material, the middle part slides through the sliding hole, and the other end is fixedly connected to the output end of the second Y-direction drive component. This improves the structural stability of the ejector rod in all states. In other words, the first vacuum furnace door not only serves as the furnace door but also as a support and guide structure for the ejector rod. Furthermore, the ejector rod can supplement the sliding hole, ensuring the sealing performance of the first vacuum furnace door and enabling material ejection even when the first vacuum furnace door is closed.

[0032] Third, the material is in contact with and moves along the plane throughout the entire process, resulting in greater friction compared to rollers. The influence of inertia on the dwell position can be ignored. Because the material's dwell position is high, the probability of equipment failure is greatly reduced, and the system can be made compact. Based on this, the size of the material can be made larger while still meeting process requirements, increasing equipment output and energy efficiency with the same power consumption.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0046] As attached Figure 1 - Appendix Figure 7 As shown, the present invention provides a vacuum furnace feeding and discharging device, including a bracket 1, a support platform 2 movable along the X direction on the bracket 1, and a material feeding component 3 and a material ejection component 4 arranged side by side along the X direction on the support platform 2. That is, the material feeding component 3 and the material ejection component 4 will move synchronously with the support platform 2. Preferably, the movement of the support platform 2 is automatic rather than manual. Specifically, a first X-direction driving component 21 is provided on the bracket 1, and the output end of the first X-direction driving component 21 is connected to the support platform 2 to drive the support platform 2 to move along the X direction.

[0047] The material feeding assembly 3 includes a material carrying platform 31 set on the support platform 2 and a material pushing member 32 that can move along the Y direction on the material carrying platform 31. The material carrying platform 31 is used to carry the material, and the material pushing member 32 is used to push the material located on the material carrying platform 31 into the vacuum furnace body 5 along the Y direction.

[0048] The material ejection assembly 4 includes a furnace door opening and closing mechanism 41 and a material ejection mechanism 42;

[0049] The furnace door opening and closing mechanism 41 includes a first Y-direction driving member 411 disposed on the support platform 2 and a first vacuum furnace door 51 disposed on the output end of the first Y-direction driving member 411. That is, the first Y-direction driving member 411 can drive the first vacuum furnace door 51 to open and close along the Y direction. In embodiments without the first Y-direction driving member 411, the first vacuum furnace door 51 is fixedly disposed on the support platform 2. The movement of the support platform 2 drives the opening and closing of the first vacuum furnace door 51. When the first vacuum furnace door 51 is opened, if the support platform 2 moves along the X direction, it will also drive the first vacuum furnace door 51 away from the vacuum furnace body 5, thereby facilitating the feeding of materials through the opening on that side of the vacuum furnace body 5.

[0050] The material ejection mechanism 42 includes a second Y-direction drive member 421 mounted on the support platform 2 and an ejection rod 422 mounted on the output end of the second Y-direction drive member 421. A sliding hole 511 is provided on the first vacuum furnace door 51, and the ejection rod 422 is slidably mounted on the sliding hole 511. When it is necessary to open the first vacuum furnace door 51, the ejection rod 422 remains fixed, and the sliding hole 511 on the first vacuum furnace door 51 slides along the ejection rod 422. When it is necessary to move the first vacuum furnace door 51 to expose the opening of the vacuum furnace body 5, The sliding hole 511 and the ejector rod 422 on the first vacuum furnace door 51 are relatively stationary and move synchronously in the X direction. When it is necessary to eject the material in the vacuum furnace body 5 from the second vacuum furnace door 52, the first vacuum furnace door 51 is fixed and cooperates with the vacuum furnace body 5. The ejector rod 422 slides along the sliding hole 511 under the drive of the second Y direction drive member 421. At this time, the end of the ejector rod 422 abuts against the material 7, the middle is slidably connected to the sliding hole 511, and the other end is fixedly connected to the output end of the second Y direction drive member 421.

[0051] The present invention, through the above-described configuration, has the following beneficial effects:

[0052] Firstly, the feeding of material 7, the opening of the first vacuum furnace door 51, the removal of the first vacuum furnace door 51 to expose the opening of the vacuum furnace body 5, and the alignment of material 7 with the opening of the vacuum furnace body 5 can all be performed simultaneously, improving the efficiency of feeding and discharging. Furthermore, material 7 can be pushed out of the vacuum furnace body 5 from the opening on the other side of the vacuum furnace body 5 while the first vacuum furnace door 51 is closed. When the vacuum furnace body 5 is connected to the heating furnace, material 7, after being evacuated of air and other gases, can be transported from the vacuum furnace body 5 to the heating furnace while the heating furnace is sealed, ensuring the sealing effect of the heating furnace at all times. This avoids heat waste in the heating furnace and saves energy.

[0053] Secondly, the ejector rod 422 and the sliding hole 511 on the first vacuum furnace door 51 are slidably engaged. On the one hand, this allows the ejector rod 422 and the first vacuum furnace door 51 to move synchronously in the X direction, maintaining their relative positions. On the other hand, the sliding hole 511 can also serve as an intermediate support structure for the ejector rod 422, transforming the original cantilever structure into a two-point support structure. During the ejection operation, it changes to a three-point support structure where the end of the ejector rod 422 abuts against the material 7, the middle part slides through the sliding hole 511, and the other end is fixedly connected to the output end of the second Y-direction drive member 421. In the initial state, one end of the ejector rod 422 engages with the sliding hole 511, and the other end is fixedly connected to the output end of the second Y-direction drive member 421, thereby improving the structural stability of the ejector rod 422 in all states. In other words, the first vacuum furnace door 51 is not only used as a furnace door but also as a support and guide structure for the ejector rod 422. In addition, the ejector rod 422 can also supplement the sliding hole 511 to ensure the sealing performance of the first vacuum furnace door 51 and enable material ejection even when the first vacuum furnace door 51 is closed. The cooperation between the ejector rod 422 and the first vacuum furnace door 51, while ensuring that material 7 can be ejected from the other end of the vacuum furnace body 5 when the first vacuum furnace door 51 is closed, improves the structural stability of the ejector rod 422 in all states and also guarantees the sealing performance of the first vacuum furnace door 51.

[0054] Third, the material is in contact with and moves along the plane throughout the entire process, resulting in greater friction compared to rollers. The influence of inertia on the dwell position can be ignored. Because the material's dwell position is high, the probability of equipment failure is greatly reduced, and the system can be made compact. Based on this, the size of the material can be made larger while still meeting process requirements, increasing equipment output and energy efficiency with the same power consumption.

[0055] In one embodiment, the ejector rod 422 is slidably sealed with the sliding hole 511, thereby ensuring the sealing performance of the first vacuum furnace door 51 and thus ensuring the sealing performance inside the vacuum furnace body 5.

[0056] In one embodiment, the sliding hole 511 is located below the connection between the first vacuum furnace door 51 and the output end of the first Y-direction drive member 411. In this embodiment, the first Y-direction drive member 411 is mounted above the ejector rod 422 via a support frame, and the ejector rod 422 passes through the support frame and is slidably connected to the sliding hole 511. This not only allows for a reasonable spatial layout, but more importantly, the ejector rod 422 can easily abut against the lower part of the material 7, improving the pushing effect while also accommodating the ejection of materials 7 with relatively low heights.

[0057] In one embodiment, the material feeding component 32 includes a third Y-direction drive component 321 disposed on the support platform 2 and a feeding component 322 disposed on the output end of the third Y-direction drive component 321. In this embodiment, the material feeding component 32 is also implemented using a drive component, which can simplify the structure and control difficulty.

[0058] In one embodiment, the material support platform 31 is provided with a slide groove 311 arranged along the Y direction, and the slide groove 311 is a through groove. Preferably, the material support platform 31 is composed of two plates with a gap between them, and the gap between the two plates forms the slide groove 311. The third Y-direction driving member 321 is arranged below the material support platform 31 to make reasonable use of the space below the material support platform 31, thereby improving the space utilization rate. The top-entry member 322 is connected to the output end of the third Y-direction driving member 321 through the vertical connecting plate 323, so that the top-entry member 322 is arranged above the material support platform 31 to push the material 7 above the material support platform 31. The vertical connecting plate 323 is slidably arranged in the slide groove 311, so that the top-entry member 322 can move along the Y direction of the entire material support platform 31. Preferably, the slide groove 311 is arranged in the middle of the material support platform 31 in the X direction, so that the top-entry member 322 abuts against the middle of the end of the material 7.

[0059] In one embodiment, the angle between the X and Y directions on the horizontal plane is 90°, so that the material 7 moves in a right-angle direction. At this time, the directions of the feeding device 6 and the vacuum furnace body 5 are 90°. Of course, the angle between the X and Y directions on the horizontal plane can be greater than 90° or less than 90°, and can be arranged according to specific needs.

[0060] The present invention also provides a vacuum furnace feeding and discharging system, including a vacuum furnace body 5 and a feeding device 6 as described above;

[0061] The feeding device 6 is used to supply material to the material support platform 31. Preferably, the feeding device 6 conveys material 7 to the material support platform 31 along the X direction.

[0062] The end of the vacuum furnace body 5 facing away from the first vacuum furnace door 51 is used to connect a sealing or high-pressure device. The sealing or high-pressure device can be a device with a vacuum environment or a device with a high-pressure environment, such as a heating furnace. A second vacuum furnace door 52 is provided between the sealing or high-pressure device and the vacuum furnace body 5. The second vacuum furnace door 52 can isolate and connect the sealing or high-pressure device.

[0063] In the vacuum furnace feeding and discharging system provided by this invention, the vacuum furnace body 5 can be connected to a vacuuming device and a protective gas injection device. This device can be used to perform a vacuuming operation on the material 7 before it is fed into the heating furnace, thereby removing air and other gases from the material 7. The material, now free of air and other gases, is then fed into the heating furnace in a closed state or under protective gas protection. Specifically, the other end of the vacuum furnace body 5 is directly or indirectly connected to the heating furnace, and the vacuum furnace body 5 and the heating furnace are isolated and connected through a second vacuum furnace door 52.

[0064] In one embodiment, the feeding device 6 includes a conveying roller mechanism 61 and a pushing mechanism 62 disposed on the conveying roller mechanism 61. Using the conveying roller mechanism 61 to convey materials ensures efficient conveying. Preferably, the pushing mechanism 62 is provided on each side of the conveying roller mechanism 61, including a fourth Y-direction linear drive member and a second X-direction linear drive member disposed on the output end of the fourth Y-direction linear drive member. The two opposing second X-direction linear drive members are used to clamp and release the material 7 on the conveying roller mechanism 61, or the two second X-direction linear drive members move closer together and clamp the back of the material 7. The output ends of the two fourth Y-direction linear drive members are used to transport the clamped material 7 along the Y-direction to the material support platform 31. This prevents the material from sliding under the movement of the conveying roller mechanism 61, ensuring the stability of the material 7 as it enters the material support platform 31.

[0065] In one embodiment, the vacuum furnace body 5 is a cylindrical structure. Cylindrical structures have strong pressure-bearing capacity, allowing for thinner steel plates and lighter equipment weight under the same vacuum pressure. Furthermore, this structural design allows for larger sintering materials, and the material is conveyed via a sliding conveyor 322 and an ejector rod 422, making the conveying process more reliable and faster. A moving platform 53 is provided inside the vacuum furnace body 5 to support the material 7 for dwelling and movement.

[0066] In this invention, the driving component can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder, etc. Preferably, the driving component is a linear driving component, and the driving component is a linear module driven by a servo motor to provide high-precision control.

[0067] The present invention also provides a method for feeding and discharging materials into a vacuum furnace, using the above-mentioned vacuum furnace feeding and discharging device, comprising the following steps:

[0068] S1. Control the second vacuum furnace door 52 to be closed to ensure the isolation between the sealing or high-pressure device and the vacuum furnace body 5, and prevent external air from entering the sealing or high-pressure device through the vacuum furnace body 5 during the following steps S2-S4.

[0069] S2. The support platform 2 is located in the first position of the bracket 1. In the first position, the support platform 2 is close to the feeding device 6. The feeding device 6 conveys the material 7 to the material support platform 31. Specifically, the material 7 is conveyed to the end near the material support platform 31 by the conveying roller on the conveying roller mechanism 61. At this time, the two second X-direction linear drive members move closer to each other and clamp the two sides of the material 7, or the two second X-direction linear drive members move closer to each other and clamp the back of the material 7. Then, the two fourth Y-direction linear drive members push the two second X-direction linear drive members and the material 7 to move towards the material support platform 31 until the material 7 is completely supported by the material support platform 31.

[0070] S3. Move the support platform 2 to the second position of the bracket 1. In the second position, the support platform 2 is away from the feeding device 6. At the same time, the first vacuum furnace door 51 moves away from the vacuum furnace body 5 along the X direction, so that there is no obstruction outside the first opening of the vacuum furnace body 5 on this side. Align the material carrying platform 31 with the first opening of the vacuum furnace body 5. Drive the push-in member 322 through the third Y direction drive member 321 to push the material 7 into the vacuum furnace body 5.

[0071] S4. Move the support platform 2 to the first position of the bracket 1, and the furnace door opening and closing mechanism 41 closes the first vacuum furnace door 51 along the Y direction;

[0072] S5. Vacuum the furnace body 5 to remove air and other gases from the material 7. After the vacuum furnace body 5 reaches the specified vacuum level, a protective gas is introduced into the vacuum furnace body 5. When the pressure in the protective gas is greater than or equal to the pressure in the heating furnace, the second vacuum furnace door 52 is opened. The ejector rod 422 is driven by the second Y-direction drive member 421 to eject the material 7 from the second opening of the first vacuum furnace door 51 and finally into the heating furnace for heating. After it is completely ejected into the heating furnace, the second vacuum furnace door 52 is closed, thus completing one process of feeding material 7 into the heating furnace.

[0073] Repeat steps S1-S5 to achieve feeding and vacuuming of the material in the continuous vacuum furnace. S1 and S2 can be performed simultaneously.

[0074] Before step S3, the furnace door opening and closing mechanism 41 opens the first vacuum furnace door 51 along the Y direction. At this time, the second vacuum furnace door 52 is in the closed state to ensure the sealing effect of the heating furnace. Specifically, the first Y-direction driving member 411 drives the first vacuum furnace door 51 away from the vacuum furnace body 5 along the Y direction. At this time, the first vacuum furnace door 51 is no longer in contact with the vacuum furnace body 5. This is so that when the support platform 2 moves to the second position of the bracket 1, the first vacuum furnace door 51 can easily move away from the vacuum furnace body 5 along the X direction.

[0075] The above description is merely an embodiment and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solutions of the present invention without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
