[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4The utility model provides a high-efficiency and energy-saving flow guide structure of a vacuum brazing furnace, including a heat exchange box 1, a plurality of support columns 2 are fixedly connected to the bottom of the heat exchange box 1, an air supply pipe 3 is fixedly connected to one side of the heat exchange box 1, a purification mechanism 4 is provided on one side of the air supply pipe 3, an air intake pipe 5 is fixedly connected to one side of the purification mechanism 4, a support plate 6 corresponding to the purification mechanism 4 is fixedly connected to one side of the heat exchange box 1, a flow equalizer 7 is fixedly connected to the inner wall of one side of the heat exchange box 1, a plurality of evenly distributed air outlet holes 8 are provided on the inner side of the flow equalizer 7, a mounting seat 9 is fixedly connected to the top of the mounting seat 9, a water pump 10 is fixedly connected to the top end of the water pump 10, a water inlet pipe 11 is fixedly connected to the water pump 10, a water outlet pipe 12 is fixedly connected to the bottom of the water pump 10, and an exhaust pipe 13 is fixedly connected to the other side of the heat exchange box 1.

[0024] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the bottoms of the multiple support columns 2 are fixedly connected with anti-slip sleeves. The design of the anti-slip sleeves can increase the friction between the support columns 2 and the ground, effectively preventing the heat exchange box 1 from sliding or displacing during operation, thereby improving the stability of the equipment. The anti-slip sleeves can absorb some vibrations, reduce the impact of vibrations on the equipment, maintain the normal operation of the equipment, and thus increase the service life of the heat exchange box 1.

[0025] Further as Figure 3 As shown, it is worth mentioning that the flow plate 7 is connected to the gas pipe 3 to ensure that the gas passing through the gas pipe 3 can enter the heat exchange box 1 from the air outlet 8 through the flow plate 7. The evenly distributed multiple air outlets 8 make the heat exchange more sufficient and the heat recovery effect better.

[0026] Further as Figure 2 and Figure 3 As shown, it is worth noting that the water outlet pipe 12 passes through the interior of the heat exchange box 1 and comes out from the bottom position on the other side of the heat exchange box 1, ensuring that the water outlet pipe 12 exchanges heat with the high-temperature gas inside the heat exchange box 1, thereby improving the energy utilization rate of the equipment.

[0027] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that the water outlet pipe 12 is designed in a serpentine shape. The curved design increases the surface area of ​​the water outlet pipe 12, so that the water outlet pipe 12 is in more sufficient contact with the hot air inside the heat exchange box 1, and the heat exchange effect is better. In addition, a solenoid valve is installed inside the end of the water outlet pipe 12. The solenoid valve can realize automatic control of the water flow and can be accurately adjusted according to the needs of the system to ensure that the flow rate and pressure during the heat exchange process are always maintained within the optimal range.

[0028] According to the above working process, it can be seen that: by setting up the heat exchange box 1, the high-temperature gas generated by the brazing furnace is discharged from the air inlet pipe 5, passes through the air supply pipe 3 and the flow equalizer 7, and enters the inside of the heat exchange box 1 from the air outlet 8. The water pump 10 is turned on to input water from the water inlet pipe 11 into the water outlet pipe 12. The high-temperature gas heats the outer surface of the water outlet pipe 12 inside the heat exchange box 1, thereby heating the water inside the water outlet pipe 12. The heated water is discharged from the end of the water outlet pipe 12 for the next step of utilization, effectively recovering the waste heat of the brazing furnace, greatly saving energy, and improving the working efficiency of the overall system.

[0029] Further as Figure 4 As shown, it is worth mentioning that the purification mechanism 4 includes a purification box 401 fixedly connected to the top of the support plate 6, an activated carbon adsorption plate 402 is slidably connected to the top of the purification box 401, a pull plate 403 is fixedly connected to the top of the activated carbon adsorption plate 402, a handle 404 is fixedly connected to the top of the pull plate 403, and two iron pillars 405 are fixedly connected to the bottom of the pull plate 403. Two magnet slots 406 corresponding to the iron pillars 405 are provided on the top of the purification box 401. By setting up the purification mechanism 4, the activated carbon adsorption plate 402 is used to adsorb and purify the gas discharged from the brazing furnace. The activated carbon can effectively remove volatile organic compounds and other harmful gases, reduce the health risks of operators and nearby personnel, and ensure the safety of the working environment.

[0030] Further as Figure 4 As shown, it is worth noting that the purification box 401, the air inlet pipe 5 and the air delivery pipe 3 are connected through, ensuring that the high-temperature gas entering from the air inlet pipe 5 can pass through the purification box 401 and the air delivery pipe 3 and then be smoothly discharged into the heat exchange box 1.

[0031] Further as Figure 4 As shown, it is worth mentioning that a limiting slide groove corresponding to the activated carbon adsorption plate 402 is opened inside the purification box 401, and the outer walls of the two iron columns 405 are tightly fitted with the inner walls of the corresponding magnet grooves 406. The limiting slide groove makes the installation of the activated carbon adsorption plate 402 more stable, and the iron column 405 and the magnet groove 406 cooperate to realize the detachable connection of the activated carbon adsorption plate 402, which is convenient for the staff to install and disassemble the activated carbon adsorption plate 402.

[0032] This solution has the following working process: in actual use, the high-temperature gas generated by the brazing furnace is discharged from the air inlet pipe 5, enters the purification box 401, and the activated carbon adsorption plate 402 adsorbs and purifies the gas. The purified high-temperature gas passes through the gas supply pipe 3 and the flow plate 7 and enters the heat exchange box 1 from the air outlet 8. Turn on the water pump 10 to input water from the water inlet pipe 11 into the water outlet pipe 12. The high-temperature gas heats the outer surface of the water outlet pipe 12 inside the heat exchange box 1, thereby heating the water inside the water outlet pipe 12. The heated water is discharged from the end of the water outlet pipe 12 for the next step of use, and the gas that has been purified and heat-exchanged is discharged from the exhaust pipe 13.

[0033] In summary: by setting up a heat exchange box 1, high-temperature gas heats the outer surface of the water outlet pipe 12 inside the heat exchange box 1, thereby heating the water inside the water outlet pipe 12, and the heated water is discharged from the end of the water outlet pipe 12 for further utilization, effectively recovering the waste heat of the brazing furnace, greatly saving energy, and improving the working efficiency of the overall system; by setting up a purification mechanism 4, using an activated carbon adsorption plate 402 to adsorb and purify the gas discharged from the brazing furnace, the activated carbon can effectively remove volatile organic compounds and other harmful gases, reduce the health risks of operators and nearby personnel, and ensure the safety of the working environment.
