Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, and in particular to an energy-saving sintering furnace. Background Technology

[0002] A sintering furnace is a specialized piece of equipment that enables powder compacts to obtain the required physical and mechanical properties and microstructures through sintering. Sintering furnaces are used to dry the slurry on silicon wafers, remove organic components from the slurry, and complete the sintering of aluminum back field and grid lines. In order to ensure the smooth progress of dewaxing, reduction, alloying, and microstructure transformation of powder compacts during the sintering process, precise control is required on sintering temperature, protective atmosphere, compact conveying method, heating and cooling rates, etc.

[0003] The utility model with announcement number CN220818547U relates to the field of sintering furnace technology and discloses a specific environmentally friendly and energy-saving sintering furnace, including a furnace body. A sealing door is hinged to the front of the furnace body, and a door handle is fixedly connected to the surface of the sealing door. A support column is fixedly connected to the bottom of the furnace body, and a support foot is fixedly connected to the bottom of the support column. A controller is fixedly connected to the right side of the furnace body, and a rotating motor is fixedly connected to the side of the furnace body. A vacuum pump is fixedly installed on the back of the furnace body. This utility model has a rotating motor installed on the outer surface of the furnace body. The rotating motor is connected to a rotating rod that extends into the interior of the furnace body. The rotating rod drives a rotating gear to rotate. The rotating gear is rotatably connected to a locking block at the bottom of a placement plate. A slider is provided at the bottom of the placement plate and is slidably connected to a sliding groove at the bottom of the inner wall of the furnace body. In use, starting the rotating motor allows the placement plate to automatically move to the outside of the furnace body, facilitating loading and unloading by personnel.

[0004] However, the above-mentioned technical solutions lack the function of filtering flue gas. In actual use, the sintering furnace will generate waste gas during operation. This waste gas contains a large number of harmful substances, such as heavy metals and organic matter, which will harm the environment and human health. Direct discharge without treatment poses certain safety hazards. Therefore, we propose an energy-saving sintering furnace to solve the above-mentioned problems. Utility Model Content

[0026] Reference Figures 1-4 An energy-saving sintering furnace, including

[0027] Sintering furnace 1;

[0028] The filter box 2, filter plate 3, fixed box 4, control plate 5, and fixed plate 12 are provided. The filter box 2 is fixedly connected to the top of the sintering furnace 1.

[0031] As a preferred embodiment of the present invention, the fixing mechanism includes: a transmission plate 6, a connecting rod 9 and a connecting plate 10;

[0032] The transmission plate 6 is slidably connected inside the fixed box 4. The rear side of the transmission plate 6 is fixedly connected to the front side of the control plate 5. The connecting rod 9 is rotatably connected to the inner wall of the fixed box 4, and the inner wall of the connecting rod 9 is slidably connected to the outer wall of the transmission plate 6. The connecting plate 10 is slidably connected to the inner wall of the fixed box 4, and the top of the connecting plate 10 is fixedly connected to the bottom of the fixed plate 12. The inner wall of the connecting plate 10 is slidably connected to the outer wall of the connecting rod 9. When the transmission plate 6 moves, it will push the connecting rod 9 to rotate. When the connecting rod 9 rotates, it will push the connecting plate 10 to move down. At this time, the downward movement of the connecting plate 10 will drive the fixed plate 12 to move down. The movement of the fixed plate 12 will disengage from the fixed groove, thereby unlocking the filter plate 3.

[0033] As a preferred embodiment of this utility model, a limiting frame 7 is fixedly connected to the bottom inner wall of the fixed box 4. The limiting frame 7 passes through the transmission plate 6, and the limiting frame 7 can conveniently limit the transmission plate 6, so that the transmission plate 6 can move laterally stably.

[0034] As a preferred embodiment of this utility model, a limiting spring 8 is fixedly connected to the inner wall of the fixed box 4, and the right side of the transmission plate 6 is fixedly connected to the left side of the limiting spring 8. Through the elastic force of the limiting spring 8, the transmission plate 6 can be easily pushed to reset and the control plate 5 can be driven to reset.

The top of the push spring 11 is fixedly connected to the bottom of the connecting plate 10. By using the elastic force of the push spring 11, the connecting plate 10 can be easily pushed to reset, thereby driving the fixed plate 12 to reset and engage with the fixed groove.

[0036] As a preferred embodiment of this utility model, sliding holes are provided on the rear side of the filter box 2 and the rear side of the fixed box 4. The inner walls of the two sliding holes are slidably connected to the outer wall of the control plate 5. The sliding holes facilitate the limiting of the control plate 5, so that the control plate 5 can move stably in the lateral direction.

[0037] It should be noted that the specific model of sintering furnace 1 and filter plate 3 to be used shall be selected by those skilled in the art. Furthermore, the above-mentioned sintering furnace 1 and filter plate 3 are all existing technologies and will not be elaborated upon in this solution.

[0038] The main body of the sintering furnace 1 adopts existing technology and can adopt the main body structure of the utility model patent with announcement number CN220818547U.

[0039] The working principle of this utility model is as follows: In actual use, the product undergoes high-temperature heat treatment in the sintering furnace 1. During use, the flue gas will drift into the filter box 2, where the filter plate 3 adsorbs and filters the harmful gases in the flue gas. The filtered flue gas is then discharged through the filter box 2. When the filter plate 3 needs to be replaced, the control plate 5 is pushed to move laterally. When the control plate 5 moves laterally, it will drive the transmission plate 6 to move. The movement of the transmission plate 6 will compress the limit spring 8, and at the same time, the limit frame 7 can limit the transmission plate 6, making the transmission plate 6 move laterally stably. When the transmission plate 6 moves, it will push the connecting rod 9 to rotate. The rotation of the connecting rod 9 will push the connecting plate 10 to move downward. At this time, the connecting plate 10... Moving the connecting plate 10 downwards will compress the push spring 11. At the same time, the movement of the connecting plate 10 will drive the fixing plate 12 downwards. The movement of the fixing plate 12 will disengage from the fixing groove, thereby unlocking the filter plate 3. At this time, the filter plate 3 can be pulled out for replacement. When installing the filter plate 3, insert the filter plate 3 into the filter box 2 and align the fixing groove with the fixing plate 12. At this time, release the control plate 5, and the limit spring 8 will lose its restraint and push the transmission plate 6 to reset. At the same time, the push spring 11 will lose its restraint and push the connecting plate 10 upwards to reset. The reset of the connecting plate 10 will drive the fixing plate 12 upwards and engage with the fixing groove to fix the filter plate 3, thus achieving the effect of replacing the filter plate 3 and facilitating the filtration of flue gas.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
