It has the advantages of uniform heating, high temperature and fast heating speed. The furnace body of the salt bath furnace will generate a lot of smoke during use. In order to avoid the impurities in the smoke from polluting the environment, a smoke filtration protection device needs to be designed for it.

[0003] However, the following problems were found in the implementation of the relevant technology: Although the existing device can efficiently filter smoke, the filtered smoke still has a high temperature, which causes the temperature near the device to be too high and affects the comfort of nearby workers. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a salt bath furnace fume filtration and protection device, which has the advantage of being able to rapidly cool the fume while filtering, thus preventing excessively high temperatures near the device from affecting workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a salt bath furnace fume filtration and protection device, comprising a furnace body and a heating chamber constructed at the lower part of the furnace body. Multiple exhaust pipes are inserted side-by-side on the front side of the heating chamber. A cooling filter box containing coolant is installed at the front end of each exhaust pipe.

Two connecting plates are symmetrically connected to the bottom edge of the heat-conducting plate. Two mounting grooves are symmetrically opened on the sidewalls of the connecting plates, and a cooling fan is nested inside the mounting groove.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a salt bath furnace fume filtration and protection device, including a furnace body 1 and a heating chamber constructed at the lower part of the furnace body 1. A heating device is installed inside the heating chamber to heat the furnace body 1 (it is not shown or described in detail because it is not an improvement direction). Multiple exhaust pipes are inserted side by side at the front of the heating chamber. The fume generated after the gas is burned by the heating device is discharged through the exhaust pipes. A cooling filter box 2 containing coolant is installed at the front end of the multiple exhaust pipes. The fume enters the cooling filter box 2 through the exhaust pipes. A heat-conducting plate 3 is nested at the bottom of the cooling filter box 2. Multiple heat-conducting sheets 4 are welded side by side to the top of the heat-conducting plate 3. The multiple heat-conducting sheets 4 can fully contact the coolant and fume through multiple heat-conducting holes 5, thereby quickly transferring heat to the surface of the heat-conducting plate 3 below. Multiple heat-conducting sheets 4 are evenly distributed on the surface of the heat-conducting sheet 4. Hole 5, multiple heat-conducting plates 6 are welded side by side to the bottom of the heat-conducting plate 3. The welding connection method has higher heat conduction efficiency, and multiple heat dissipation holes 7 are evenly opened on the surface of the heat-conducting plate 6. The heat on the surface of the heat-conducting plate 3 will be conducted to the surface of the multiple heat-conducting plates 6 below. Two connecting plates 8 are symmetrically connected to the bottom edge of the heat-conducting plate 3 by multiple sets of screws. Two mounting slots are symmetrically opened on the side wall of the connecting plate 8, and a cooling fan 9 is nested in the inner side of the mounting slot. The cooling fans 9 on both sides have the same airflow direction, which can continuously blow air on the multiple heat-conducting plates 6 for heat dissipation. The airflow increases the contact area with the heat-conducting plates 6 through the multiple heat dissipation holes 7 to quickly dissipate the heat on their surface. An exhaust pipe 15 is inserted into the front side wall of the cooling filter box 2. The cooled and filtered smoke is discharged through the exhaust pipe 15. A filter assembly is installed inside the cooling filter box 2.

[0023] Specifically, it also includes a support plate 10 supported on the front of the top of the cooling filter box 2 and a mesh frame 11 connected to the bottom of the support plate 10 by multiple screws. The mesh frame 11 is inserted between the left and right inner walls of the cooling filter box 2 to ensure that the smoke passes through the mesh frame 11. Multiple filter plates 12 are connected side by side to the bottom of the inner side of the mesh frame 11 by multiple sets of screws. The multiple filter plates 12 work together to effectively filter the smoke.

[0024] Furthermore, two connectors 13 are glued side by side to the front side of the support plate 10, and two fixing parts located below the connectors 13 are glued side by side to the front side of the cooling filter box 2. The connectors 13 and the corresponding fixing parts are screwed together with fixing screws. The connectors 13 and the fixing parts can be fixed by fixing screws, thereby fixing the support plate 10 to the top of the cooling filter box 2. The support plate 10 can be lifted up and taken out by removing the fixing screws.

[0025] Furthermore, a handle 14 is connected to the top of the support plate 10 by screws, which facilitates the movement of the support plate 10 and the mesh frame 11, and the support plate 10 is flush with the edge of the cooling filter box 2.

[0026] It is worth noting that two sets of support legs 16 are symmetrically installed at the bottom of the furnace body 1. The two sets of support legs 16 are used to support the furnace body 1. The top of the furnace body 1 is hinged with a top cover 20. The workpiece can be processed inside the furnace body 1 by covering the top cover 20.

[0027] It is worth noting that a storage box 17 is installed between the two sets of support legs 16 by multiple sets of screws, which can be used to temporarily store workpieces. Multiple partitions 18 are connected in parallel and longitudinally on the inner side of the storage box 17. The multiple partitions 18 can divide multiple spaces to store different workpieces in categories.

[0028] It is worth mentioning that a nameplate 19 is affixed to the right outer wall of the furnace body 1. The operating instructions are marked on the surface of the nameplate 19 so that the staff can understand them. Furthermore, a protective film is affixed to the surface of the nameplate 19 to prevent the operating instructions from becoming unclear due to wear.

[0029] The cooling fan 9 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: During the workpiece processing in the furnace body 1, smoke is continuously discharged from the heating chamber through the exhaust pipe. The smoke enters the cooling filter box 2 through the exhaust pipe and first comes into contact with multiple heat-conducting plates 4. The multiple heat-conducting plates 4 can fully contact the coolant and smoke through multiple heat-conducting holes 5, thereby quickly transferring heat to the surface of the heat-conducting plate 3 below. The heat on the surface of the heat-conducting plate 3 will be transferred to the surface of multiple heat-conducting plates 6 below. The cooling fans 9 on both sides can continuously blow air onto the multiple heat-conducting plates 6 to dissipate heat. The air blows through multiple heat dissipation holes 7 to increase the contact area with the heat-conducting plates 6 and quickly dissipate the heat on their surface, so that the device can continuously and quickly cool the smoke. Then the smoke will pass through multiple filter plates 12 in the mesh frame 11. The multiple filter plates 12 work together to effectively filter the smoke. The cooled and filtered smoke is discharged through the exhaust pipe 15.
