[0002] Vertical controlled atmosphere multi-purpose furnaces are widely used in industrial fields such as metal heat treatment. However, traditional vertical controlled atmosphere multi-purpose furnaces generate a large amount of waste heat during operation. If this waste heat is not utilized, it not only wastes energy but may also have a certain impact on the surrounding environment. At the same time, the gas discharged from the furnace may contain impurities and flue gas, and direct emission will pollute the environment. Currently, there is a lack of vertical controlled atmosphere multi-purpose furnaces on the market that can efficiently utilize waste heat and effectively treat the discharged gas. Therefore, it is of great significance to develop a vertical controlled atmosphere multi-purpose furnace with a waste heat utilization mechanism and the ability to purify the discharged gas. Based on this, a vertical controlled atmosphere multi-purpose furnace with a waste heat utilization mechanism is proposed to solve the above problems. Utility Model Content

[0023] 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.

[0024] Example 1:

[0025] Traditional vertical controlled atmosphere multi-purpose furnaces generate a large amount of waste heat during operation. If this waste heat is not utilized, it not only wastes energy but may also have a certain impact on the surrounding environment. At the same time, the gas discharged from the furnace may contain impurities and flue gas, and direct emission of these gases will pollute the environment. This embodiment provides a vertical controlled atmosphere multi-purpose furnace with a waste heat utilization mechanism. Please refer to [reference needed]. Figures 1-5 An embodiment provides a vertical controllable atmosphere multi-purpose furnace with a waste heat utilization mechanism, including a furnace body support 1, a furnace body 2 fixedly installed on the top of the furnace body support 1, a waste heat utilization pipe 8 connected to the furnace body 2, a connecting conduit 9 connected to the top of the waste heat utilization pipe 8, a connecting assembly 10 connected to the connecting conduit 9, and a water tank 11 connected to the connecting assembly 10; the connecting assembly 10 includes a connecting insulation box 1001 connected to the inside of the connecting conduit 9, an exhaust pipe 1002 connected to the bottom of the connecting insulation box 1001, and a connecting interface 1003 connected to the outer wall of the water tank 11. An installation box 1004 is slidably connected to the inner wall of the heat insulation box 1001. A multi-layer filter plate 1005 is fixedly installed on the inner wall of the installation box 1004. A fixing box 1006 is fixedly connected to the top of the installation box 1004. A slide rod 1007 is slidably connected to the inner wall of the fixing box 1006. A connecting spring 1008 is sleeved on the inner side of the slide rod 1007. A slider 1009 is fixedly connected to one end of the back of the slide rod 1007. A connecting rod 1010 is fixedly connected to the front of the slide rod 1007. An insert block 1011 is fixedly connected to the back of the connecting rod 1010. A limit block 1012 is fixedly connected to the front of the heat insulation box 1001.

[0026] In this embodiment, the furnace body 2 is used for metal heat treatment and other processing operations, generating a large amount of waste heat during operation. The generated waste heat is collected through channels such as the flue gas pipe 14 to the waste heat utilization pipe 8. The waste heat utilization pipe 8 is fixedly installed on the outer wall of the furnace body support 1 and is arranged in a U-shape, which can effectively collect and guide the waste heat. The waste heat rises along the waste heat utilization pipe 8 and is transmitted to the connecting assembly 10 through the connecting conduit 9 connected at the top. The waste heat enters the connecting insulation box 1001, where the multi-layer filter plates 1005 on the inner wall of the mounting box 1004 filter the flue gas mixed in with the waste heat. The multi-layer filter plates 1005 can more effectively intercept impurities and purify the gas. When it is necessary to install or remove the mounting box 1004 for cleaning or replacing the filter plates, the sliding rod 1007 is pulled. The sliding rod 1007 slides on the inner wall of the fixed box 1006, simultaneously compressing the connecting spring 1008, carrying... The moving connecting rod 1010 and the insert block 1011 move, causing the insert block 1011 to slide out from the inner wall of the limiting block 1012, allowing the installation box 1004 to be removed. During installation, the installation box 1004 is placed into the connecting heat insulation box 1001, the sliding rod 1007 is released, the connecting spring 1008 is reset, and the insert block 1011 is inserted into the inner wall of the limiting block 1012 for fixation. The filtered waste heat enters the water tank 11 through the exhaust pipe 1002 and the connecting interface 1003. Since the connecting heat insulation box 1001 is connected at the connection between the connecting interface 1003 and the water tank 11, it ensures that the waste heat enters the water tank smoothly. The waste heat entering the water tank 11 heats the water in the water tank, realizing the recovery and utilization of waste heat, which can be used for other processes or domestic purposes that require hot water.

[0027] Furthermore, the heat insulation box 1001 is connected to the connection between the connection interface 1003 and the water tank 11; the multi-layer filter plate 1005 is arranged in multiple layers to filter the flue gas mixed in with the heat discharged by the connecting conduit 9; the slider 1009 is slidably connected to the inner wall of the fixed box 1006, and the insert block 1011 is slidably connected to the inner wall of the limiting block 1012; the waste heat utilization pipe 8 is fixedly installed on the outer wall of the furnace body support 1, and the waste heat utilization pipe 8 is arranged in a U-shape.

[0028] Furthermore, when it is necessary to install or remove the installation box 1004 for cleaning or filter plate replacement, pull the slide rod 1007. The slide rod 1007 slides on the inner wall of the fixed box 1006, while compressing the connecting spring 1008, which drives the connecting rod 1010 and the insert block 1011 to move, so that the insert block 1011 slides out from the inner wall of the limiting block 1012, and the installation box 1004 can be removed. During installation, place the installation box 1004 into the connecting heat insulation box 1001, release the slide rod 1007, the connecting spring 1008 returns to its original position, and the insert block 1011 is inserted into the inner wall of the limiting block 1012 for fixation. The filtered residual heat enters the water tank 11 through the exhaust pipe 1002 and the connecting interface 1003.

[0029] Example 2:

[0030] Based on Embodiment 1, a retractable door curtain 3 is fixedly installed on the upper section of the furnace body 2, a feeding roller 5 is fixedly installed on the inner wall of the front section of the furnace body 2, and a receiving base frame 6 is fixedly connected to the connection between the furnace body support 1 and the front end of the furnace body 2; a controller 13 is fixedly installed on the top left side of the furnace body support 1, flue gas pipes 14 are connected to both sides of the furnace body 2, and a receiving frame 12 is fixedly installed at the bottom of the water tank 11.

[0031] In this embodiment, the upper section of the furnace body 2 has a retractable door curtain 3 that can be closed when not in use, which serves to keep the furnace warm and prevent dust from entering. The feed roller 5 facilitates the feeding of the workpiece to be processed into the furnace body 2. The support frame 6 is used to support the workpiece entering and leaving the furnace body, ensuring the stability of the workpiece transportation. The controller 13 on the top left side of the furnace body support 1 is used to control the operating parameters of the furnace body 2 and the working status of the entire waste heat utilization system.

[0032] Working principle: The furnace body 2 is used for metal heat treatment and other processing operations. During operation, a large amount of waste heat is generated. The waste heat is collected through channels such as the flue gas pipe 14 to the waste heat utilization pipe 8. The waste heat utilization pipe 8 is fixedly installed on the outer wall of the furnace body support 1 and is arranged in a U-shape, which can effectively collect and guide the waste heat. The waste heat rises along the waste heat utilization pipe 8 and is transmitted to the connecting assembly 10 through the connecting conduit 9 connected at the top. The waste heat enters the connecting insulation box 1001 and the multi-layered inner wall of the installation box 1004. Filter plate 1005 filters the flue gas mixed in with waste heat. The multi-layered filter plate 1005 can more effectively intercept impurities and purify the gas. When it is necessary to install or remove the installation box 1004 for cleaning or replacement of filter plates, pull the slide rod 1007. The slide rod 1007 slides on the inner wall of the fixed box 1006, while compressing the connecting spring 1008, which drives the connecting rod 1010 and the insert block 1011 to move. This causes the insert block 1011 to slide out from the inner wall of the limit block 1012, and the installation box 1004 can then be removed. 04; During installation, place the installation box 1004 into the connecting insulation box 1001, loosen the slide rod 1007, reset the connecting spring 1008, and insert the plug 1011 into the inner wall of the limiting block 1012 to achieve fixation; the filtered waste heat enters the water tank 11 through the exhaust pipe 1002 and the connecting interface 1003. Since the connecting insulation box 1001 is connected to the connection between the connecting interface 1003 and the water tank 11, it ensures that the waste heat can smoothly enter the water tank; the waste heat entering the water tank 11 purifies the water in the water tank. Heating enables the recovery and utilization of waste heat, which can be used in other processes or for domestic purposes that require hot water; the roll-up curtain 3 on the upper section of the furnace body 2 can be closed when not in use, serving to keep the furnace warm and prevent dust from entering; the feed roller 5 facilitates the feeding of workpieces into the furnace body 2; the supporting frame 6 is used to support workpieces entering and leaving the furnace body, ensuring the stability of workpiece transportation; the controller 13 on the top left side of the furnace body support 1 is used to control the operating parameters of the furnace body 2 and the working status of the entire waste heat utilization system.
