[0002] Microwave smelting furnaces are industrial equipment that solve the problems of traditional smelting furnaces, such as long process flow, large-scale engineering, huge cost, and large environmental pollution.

[0003] A search of Chinese Patent Publication No. CN 213740540 U discloses a novel microwave heating furnace, comprising a furnace body, a fixed support, an end door, an electric push rod, a cooling assembly, and a heating assembly. The furnace body has a downward-opening heating cavity, with an inlet and outlet on the side wall of the heating cavity. The fixed support is installed at the lower end of the furnace body to raise it. The end door is pivotally fitted to the upper edge of the inlet and outlet. The electric push rod is installed on the side wall of the furnace body, and its output end is connected to the end door to realize the opening and closing of the end door. The heating assembly includes several waveguides disposed on the surface of the furnace body and magnetrons mounted on the waveguides. The cooling assembly is used to cool the magnetrons. This invention, by setting up the waveguides and magnetrons, guides the electromagnetic waves through the waveguides, achieving uniform heating of the material in the heating cavity during use, and uses liquid cooling to dissipate heat from the magnetrons.

[0004] The heating furnace described in the aforementioned patent still has certain shortcomings. In actual use, the materials used for sintering are mostly directly fed into the heating furnace for heating and combustion. Since there is only one feeding channel, the materials fed onto the combustion plate are prone to accumulation, which leads to slow overall heating of the materials, low heating efficiency, and increased overall production costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a microwave sintering heating furnace, which solves the problem that in actual use, most of the materials used for sintering are directly fed into the furnace for heating and combustion, and the feeding channel is only a single one. This causes the materials fed onto the combustion plate to easily accumulate, resulting in slow overall heating of the materials, low heating efficiency, and increased overall production costs.

[0006] This utility model provides the following technical solution: a microwave sintering heating furnace, including a sintering furnace body, a bottom support plate provided at the bottom end of the sintering furnace body, a material support plate provided inside the sintering furnace body, a dispersing and feeding assembly provided at the top of the sintering furnace body, a top closing assembly provided at the top of the dispersing and feeding assembly, a material receiving port provided on the side of the sintering furnace body, and a closing door rotatably provided on the material receiving port;

[0007] The dispersing and feeding assembly includes a top feeding hopper located at the top of the sintering furnace body. Three feeding channels are evenly distributed at the bottom of the top feeding hopper. A bottom feeding box is located at the top of the sintering furnace body, and three dispersing and dropping holes are evenly distributed on the bottom feeding box. The dispersing and dropping holes are connected to the feeding channels via a feeding connecting pipe. A rotating rod is rotatably inserted into the bottom of the top feeding hopper. A drive motor is located on the outside of the top feeding hopper, and the drive shaft of the drive motor is fixedly connected to the end of the rotating rod. A rotating connecting plate is located on the other side of the top feeding hopper, and the end of the rotating rod is rotatably connected to the rotating connecting plate. Several baffles are evenly distributed on the rotating rod, and the baffles are located within the feeding channels.

[0008] Preferred technical solution 1: The top closing assembly includes a top closing plate disposed at the top of the top of the top hopper, and side connecting blocks are symmetrically disposed on both sides of the top of the top of the top hopper. The side connecting blocks and the top closing plate are rotatably connected by a rotating pin.

[0009] Preferred technical solution 2: A first fixed connecting plate is provided at the end of the top closing plate, and a fixing screw is inserted through the first fixed connecting plate.

[0010] Preferred technical solution 3: A second fixed connecting plate is provided on the side of the top of the top hopper, and the second fixed connecting plate is provided with connecting screw holes.

[0011] Preferred technical solution four: Support blocks are evenly arranged around the bottom of the sintering furnace body.

[0012] Preferred technical solution five: The inner wall of the bottom of the top discharge hopper is inclined.

[0013] This solution allows materials entering the top hopper to more easily accumulate at the top of the discharge channel.

[0014] Preferred technical solution six: The top opening of the dispersing and falling hole is smaller than the bottom opening.

[0015] This solution allows the material entering the dispersing holes to fall and scatter over a larger area.

[0016] Preferred technical solution seven: The side of the drive motor is connected by a fixed frame.

[0017] Preferred technical solution eight: The side of the baffle is arc-shaped, and the side wall of the baffle is in contact with the inner wall of the feeding channel.

[0018] This solution enables the baffle to not only move the material entering the feeding channel, but also to prevent the material from falling.

[0019] Preferred technical solution nine: The inner wall of the connecting screw hole is provided with an internal thread, and the fixing screw is threadedly inserted into the connecting screw hole.

[0020] This solution allows the fixing screw to be inserted into the connecting screw hole more securely.

[0021] Compared with the prior art, the present invention provides a microwave sintering heating furnace, which has the following beneficial effects:

[0022] (1) This utility model has a dispersing and feeding component on the sintering furnace body. The top feeding hopper of the dispersing and feeding component can not only complete the feeding of materials, but also buffer the materials briefly. When feeding is required, the user starts the drive motor, which drives the rotating rod to rotate the baffle, so that the materials entering the feeding channel can fall into the dispersing and falling hole. The bottom opening of the dispersing and falling hole is larger than the top opening, so that the materials can be more dispersed when falling into the dispersing and falling hole. With three dispersing and falling holes, the materials can fall more dispersedly onto the material support plate, which effectively avoids the accumulation of sintering materials when adding them. The dispersed materials can be sintered more evenly in the sintering furnace body, and the overall heating is better and faster, so that the materials are sintered more thoroughly, thereby providing good sintered products for subsequent processing, improving the overall quality of the products, improving heating efficiency, and reducing the production costs required.

[0030] Please see Figure 1-4 ,

[0031] Example 1: A microwave sintering heating furnace includes a sintering furnace body 1, a bottom support plate 2 at the bottom end of the sintering furnace body 1, a material support plate 3 inside the sintering furnace body 1, a dispersing and feeding assembly 4 at the top of the sintering furnace body 1, a top closing assembly 5 at the top of the dispersing and feeding assembly 4, a material receiving port 6 on the side of the sintering furnace body 1, and a closing door 7 rotatably mounted on the material receiving port 6.

[0032] The dispersing and feeding assembly 4 includes a top feeding hopper 401 located at the top of the sintering furnace body 1. Three feeding channels 402 are evenly distributed at the bottom of the top feeding hopper 401. A bottom feeding box 403 is located at the top of the sintering furnace body 1. Three dispersing and dropping holes 404 are evenly distributed on the bottom feeding box 403. The dispersing and dropping holes 404 are connected to the feeding channels 402 by a feeding connecting pipe 405. A rotating rod 406 is rotatably inserted at the bottom of the top feeding hopper 401. A drive motor 407 is located on the outside of the top feeding hopper 401. The drive shaft of the drive motor 407 is fixedly connected to the end of the rotating rod 406. A rotating connecting plate 408 is located on the other side of the top feeding hopper 401. The end of the rotating rod 406 is rotatably connected to the rotating connecting plate 408. Several baffles 409 are evenly distributed on the rotating rod 406. The baffles 409 are located in the feeding channels 402.

[0033] The top closing assembly 5 includes a top closing plate 501 disposed at the top of the top hopper 401. Side connecting blocks 502 are symmetrically disposed on both sides of the top of the top of the top hopper 401. The side connecting blocks 502 and the top closing plate 501 are rotatably connected by a rotating pin 503. A first fixed connecting plate 504 is disposed at the end of the top closing plate 501. A fixing screw 505 is inserted through the first fixed connecting plate 504. A second fixed connecting plate 506 is disposed on the side of the top of the top of the top hopper 401. A connecting screw hole 507 is opened on the second fixed connecting plate 506.

[0034] Example 2: The difference between this example and Example 1 is that support blocks are evenly arranged around the bottom of the sintering furnace body 1.

[0035] Example 3: The difference between this example and Example 1 is that the inner wall of the bottom of the top hopper 401 is inclined.

[0036] This makes it easier for the material entering the top hopper 401 to gather at the top of the discharge channel 402.

[0037] Example 4: The difference between this example and Example 1 is that the top opening of the dispersing drop hole 404 is smaller than the bottom opening.

[0038] This results in a larger area of ​​material falling and scattering after entering the dispersing and dropping holes 404.

[0039] Example 5: The difference between this example and Example 1 is that the side of the drive motor 407 is connected by a fixed bracket.

[0040] Example 6: The difference between this example and Example 1 is that the side of the baffle 409 is arc-shaped, and the side wall of the baffle 409 is in contact with the inner wall of the feeding channel 402.

[0041] This allows the baffle 409 to not only move the material entering the feeding channel 402, but also prevent the material from falling.

[0042] Example 7: The difference between this example and Example 1 is that the inner wall of the connecting screw hole 507 is provided with an internal thread, and the fixing screw 505 is threadedly inserted into the connecting screw hole 507.

[0043] This makes the fixing screw 505 more securely inserted into the connecting screw hole 507.

[0044] In this embodiment, since most of the materials used in the existing microwave sintering heating furnace are directly fed into the furnace for heating and combustion, and there is only one feeding channel, the materials fed onto the combustion plate are prone to accumulation, which leads to slow overall heating of the materials, low heating efficiency, and increased overall production costs.

[0045] In summary, in specific implementation, when the user needs to heat and sinter the material, the user first needs to put the material into the top hopper 401 in the dispersing and feeding component 4. Since the bottom of the top hopper 401 is inclined, the material is better gathered at the top of the feeding channel 402, making it easier for the material to fall from the feeding channel 402.

[0046] Furthermore, since a baffle 409 is provided in the feeding channel 402, the baffle 409 can temporarily close the feeding channel 402 before it rotates, thereby preventing the material from falling when it is added. When the user needs to add material for sintering, the user can start the drive motor 407 to drive the rotating rod 406 to rotate, so that the rotating rod 406 can drive the baffle 409 to rotate, and the material falling in will fall at the same time, so that the material can fall into the dispersing falling hole 404 at the same time. And since the bottom opening of the dispersing falling hole 404 is larger than the top opening.

[0047] This allows the material to spread out over a larger area when it falls, enabling it to be effectively laid on the material support plate 3. The material is spread out more dispersedly on the material support plate 3, thus effectively avoiding the accumulation of sintering material during addition. The dispersed material can then be sintered more evenly in the sintering furnace body 1, and the overall heating is better and faster, resulting in more thorough sintering of the material. This provides good sintered products for subsequent processing, improves the overall quality of the products, increases heating efficiency, and reduces the production costs required.
