Technical Field

[0001] This utility model relates to the field of sintering furnace technology, specifically a stacked sintering furnace device. Background Technology

[0002] A sintering furnace is a heat treatment device that uses high temperatures to bond the solid particles of ceramic green bodies together and to sinter metal powders or mixtures of metal powders and non-metal powders as raw materials to produce metal or alloy parts. It is mainly used for pressing and forming iron-based, copper-based and other related powder metallurgy products and ceramics.

[0003] For example, the utility model patent application No. 202420742056.3 discloses a multi-layer sintering furnace structure, including a sintering furnace body, a recycling box fixedly installed at the rear end of the sintering furnace body, a fan fixedly installed at the rear end inside the recycling box, a fixing mechanism slidably installed on the other side inside the sintering furnace body, and two fixing frames fixedly installed at the upper end of the fixing mechanism, the two fixing frames including limiting blocks.

[0004] Taking the aforementioned sintering furnace as an example, although the interior of the sintering furnace will be modified to enable the furnace to process multiple layers of materials at one time, heating equipment also needs to be installed in multiple locations inside the sintering furnace. The different locations of the heating equipment lead to high labor costs for testing whether the heating equipment is working properly and for repairing and replacing individual heating equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a stacked sintering furnace device to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacked sintering furnace device, including a sintering furnace and a sealing door, wherein multiple temperature control components are arranged inside the sintering furnace, each of the temperature control components including a sealing block, an infrared thermometer, a chain lifting device and two guide rails, wherein a guide groove is provided at the top of the inner cavity of one of the guide rails, and multiple resistance heaters are arranged between the two guide rails in one of the temperature control components, and a support component is arranged between two adjacent temperature control components.

[0007] Preferably, the support assembly includes two guide rails, which are respectively fixedly connected to the two sides inside the sintering furnace. Multiple drag-reducing rollers are rotatably installed at the bottom and top of the inner cavity of each guide rail.

[0008] Preferably, in one of the support components, side plates are inserted inside both of the two guide rails, and a material carrier plate is fixedly connected between the two side plates. The top of the material carrier plate has multiple material carrier cavities.

[0009] Preferably, in the temperature control component, the two guide rails are respectively fixedly connected to the two sides inside the sintering furnace, and a support frame is provided inside each of the two guide rails. A U-shaped frame is sleeved on the outer side of both ends of the resistance heater, and the U-shaped frame is fixedly installed on the top of the adjacent support frame.

[0010] Preferably, the sealing block is installed at the rear of the sintering furnace, and a square mounting bracket is fixedly connected to one side of the sealing block. The infrared thermometer is fixedly installed inside the square mounting bracket.

[0011] Preferably, the chain lifting device is fixedly installed on the rear side of the sintering furnace, and the chain of the chain lifting device is fixedly connected to the square mounting frame.

[0012] Preferably, multiple hinges are installed between one side of the sealing door and the sintering furnace, a pressure sensor and a temperature sensor are fixedly installed on the outside of the sealing door, and two gate valves are fixedly connected to the rear side of the sintering furnace.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When this application is used, the chain lifting equipment pushes the sealing block to move, and the infrared thermometer moves inside the guide groove. When the infrared thermometer moves to the top of the resistance heater, it works once to measure the temperature of the resistance heater. This can quickly detect whether multiple resistance heaters are working properly. When a resistance heater needs to be replaced, a pulling force is applied to the two support frames set at both ends of the resistance heater, which can make the resistance heater leave the sintering furnace. The resistance heater is taken out between the two U-shaped frames, and the new resistance heater is placed between the two U-shaped frames. This completes the replacement of the damaged resistance heater and can quickly complete the positioning and replacement of the damaged resistance heater.

[0014] 2. When this application is used, multiple drag-reducing rollers support the side plates while reducing the resistance to the movement of the side plates, reducing the possibility of material plate swaying, ensuring the stability of material movement inside the material loading chamber, and improving the quality of sintering. The material loading plate and the heat-conducting frame composed of two side plates are installed in multiple support components in sequence to complete the material loading work inside the sintering furnace. Multiple heat-conducting frames are placed inside the sintering furnace. Multiple resistance heaters that play a heating role are distributed on the top and bottom of the material loading plate to ensure that the material is heated evenly, improve the processing quality, process multiple batches of material at one time, ensure the production capacity of the sintering furnace, and reduce the cost input required for sintering a single material.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-5 As shown, this utility model provides a technical solution for a stacked sintering furnace, including a sintering furnace 1 and a sealing door 2. The sintering furnace 1 is equipped with multiple temperature control components. Each temperature control component includes a sealing block 16, an infrared thermometer 18, a chain lifting device 19, and two guide rails 11. One of the guide rails 11 has a guide groove 15 at the top of its inner cavity. Multiple resistance heaters 14 are arranged between the two guide rails 11 in one of the temperature control components. A support component is arranged between two adjacent temperature control components. The two guide rails 11 in the temperature control components are fixedly connected to the two sides inside the sintering furnace 1. A support frame 12 is arranged inside each of the two guide rails 11. U-shaped frames 13 are fitted on the outer sides of both ends of the resistance heaters 14. The U-shaped frames 13 are fixedly installed on the top of the adjacent support frames 12. The sealing block 16 passes through the rear side of the sintering furnace 1. A square mounting frame 17 is fixedly connected to one side of the sealing block 16. The infrared thermometer 18 is fixedly installed inside the square mounting frame 17.

[0019] Specifically, multiple temperature control components are installed inside the sintering furnace 1. A support component is installed between two adjacent temperature control components. Each support component includes two guide rails 9. The two guide rails 9 are fixedly connected to the two sides inside the sintering furnace 1. Multiple drag-reducing rollers 10 are rotatably installed at the bottom and top of the inner cavity of the guide rails 9. The multiple drag-reducing rollers 10 rotate to reduce drag.

[0020] Multiple material-carrying cavities 7 are provided on the top of the material-carrying plate 6. The material-carrying cavities 7 are used to carry materials and shape them. Side plates 8 are fixedly installed on both sides of the material-carrying plate 6. After aligning the two side plates 8 with the two guide rails 9 in a support assembly, the material-carrying plate 6 is pushed, causing the side plates 8 to move into the sintering furnace 1. Multiple drag-reducing rollers 10 support the side plates 8 while reducing the resistance to the movement of the side plates 8, reducing the possibility of the material-carrying plate 6 shaking, ensuring the stability of the material movement inside the material-carrying cavities 7, and improving the quality of sintering. The heat-conducting load rack composed of the material-carrying plate 6 and the two side plates 8 is installed in multiple support assemblies in sequence to complete the material loading work inside the sintering furnace 1. Multiple heat-conducting load racks are placed inside the sintering furnace 1 to process multiple batches of materials at one time, ensuring the production capacity of the sintering furnace 1 and reducing the cost input required for sintering a single material.

[0021] In the temperature control assembly, two guide rails 11 are fixedly connected to the two sides inside the sintering furnace 1. A support frame 12 is provided inside each of the two guide rails 11. A U-shaped frame 13 is fitted on the outer side of both ends of the resistance heater 14. The U-shaped frame 13 is fixedly installed on the top of the adjacent support frame 12, and the resistance heater 14 is supported and suspended. Since the support assembly is set between the two temperature control assemblies, multiple resistance heaters 14 that play a heating role are distributed on the top and bottom of the material plate 6, ensuring that the material is heated evenly and improving the processing quality.

[0022] The sealing block 16 is inserted through the rear side of the sintering furnace 1 and aligned with the adjacent guide groove 15. A square mounting bracket 17 is fixedly connected to one side of the sealing block 16. An infrared thermometer 18 is fixedly inserted inside the square mounting bracket 17. The sealing block 16, the square mounting bracket 17, and the infrared thermometer 18 move synchronously. The chain lifting device 19 is fixedly installed at the rear side of the sintering furnace 1, and the chain of the chain lifting device 19 is fixedly connected to the square mounting bracket 17. Before sealing the sintering furnace 1, multiple resistance heaters 14 are controlled to operate at low power for a period of time. Then, the chain lifting device 19 is controlled to work and push the sealing block 16 to move. The infrared thermometer 18 moves inside the guide groove 15. When the infrared thermometer 18 moves to the top of the resistance heater 14, it works once to measure the temperature of the resistance heater 14. This allows for a quick check of whether multiple resistance heaters 14 are working properly. When a resistance heater 14 needs to be replaced, a pulling force is applied to the two support frames 12 at both ends of the resistance heater 14 to remove it from the sintering furnace 1. The resistance heater 14 is then taken out between the two U-shaped frames 13, and a new resistance heater 14 is placed between the two U-shaped frames 13. This completes the replacement of the damaged resistance heater 14 and allows for a quick and easy replacement of the damaged resistance heater 14.

[0023] When the chain lifting device 19 operates and drives the sealing block 16 to reset, the sealing block 16 and the sintering furnace 1 return to the interference fit state, and the sealing block 16 seals the sintering furnace 1.

[0024] Multiple hinges are installed between one side of the sealing door 2 and the sintering furnace 1. After the resistance heater 14 finishes its detection, the sealing door 2 is closed, so that the interior of the sintering furnace 1 is sealed. A pressure sensor 3 and a temperature sensor 4 are fixedly installed on the outside of the sealing door 2. The pressure sensor 3 detects the internal pressure of the sintering furnace 1, and the temperature sensor 4 detects the internal temperature of the sintering furnace 1.

[0025] Two gate valves 5 are fixedly connected to the rear side of the sintering furnace 1. One gate valve 5 is connected to a vacuum pump to discharge the gas inside the sintering furnace 1, and the other gate valve 5 is connected to a hot air system to deliver hot air into the sintering furnace 1 before opening the sealing door 2, thereby reducing losses caused by excessive temperature difference.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
