DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a brass baking furnace for waste heat recovery, comprising a baking furnace body 1, a support plate 2 is fixedly connected to the left side of the baking furnace body 1, a recovery component 300 for recovering waste heat is installed on the top of the support plate 2, and a filtering component 500 for filtering waste slag is installed on the top of the baking furnace body 1; through the coordinated use of the recovery component 300 and the filtering component 500 on the left side of the baking furnace body 1, the waste heat can be more fully and effectively recovered, the waste heat can be effectively recovered through efficient heat exchange, and the recovered waste heat can be transported back to the inside of the baking furnace for repeated use after treatment, and it can also adapt to long-term continuous use, which not only reduces the loss of heat energy, but also indirectly reduces the workload of the staff, which is very convenient and practical.

[0025] It should be noted that the baking furnace body 1 is a furnace body that can be used for metal baking and heating. It is an existing public technology, so no further details are given. A slag discharge mechanism 401 is fixedly installed at the bottom of the baking furnace body 1. The slag discharge mechanism 401 can be composed of a slag discharge pipe and a valve, which can control the discharge of waste slag. It can also be other structures with switching capabilities and suitable for high-temperature waste slag discharge. A placement pipe 402 is fixedly connected to the front of the baking furnace body 1. The placement pipe 402 is a channel for placing brass metal workpieces.

[0026] It should also be noted that two air inlet pipes 403 are fixedly connected to the front of the baking oven body 1. The air inlet pipes 403 are pipelines for transporting coal gas and compressed air, which can play a role in auxiliary combustion. The high-temperature gas entering in conjunction with the return air pipe 311 can more quickly increase the temperature inside the baking oven body 1, thereby saving heat energy while recovering waste heat.

[0027] In this embodiment, the recovery component 300 is a structure for recovering waste heat for repeated utilization.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the recycling component 300 includes a recycling box 301 fixedly connected to the top of the support plate 2, a docking pipe 302 is penetrated and fixedly connected to the top of the recycling box 301, a heat exchange elbow 303 is fixedly connected to the bottom end of the docking pipe 302, and the outer side of the heat exchange elbow 303 is fixedly connected with evenly distributed heat exchange fins 304, and the top and bottom of the heat exchange fins 304 are fixedly connected with evenly distributed auxiliary heat exchange fins 305, and four air inlet boxes 306 are penetrated and fixedly connected to the left side of the recycling box 301, and a high-temperature resistant fan 307 is fixedly installed inside the air inlet box 306. The high-temperature resistant fan 307 is a blowing device that can be used in high-temperature places, and a filter screen 308 is connected to the left side of the air inlet box 306 by screws, and two exhaust pipes 309 are penetrated and fixedly connected to the right side of the recycling box 301, and the right end of the exhaust pipe 309 is fixedly connected to the delivery pipe 310, and the front of the baking oven body 1 is fixedly connected to the return air pipe 311.

[0029] It should be noted that the inner diameter of the top of the docking tube 302 is larger than the inner diameter of the bottom end, so that the airflow can change from coarse to fine, and when the fluid changes from coarse to fine, the speed of the fluid will be accelerated, so that the airflow can be transported normally. The top of the heat exchange bend 303 is fixedly connected to the inner top wall of the recovery box 301, and the outer side of the heat exchange bend 303 is fixedly connected to the top of the support plate 2, so that the heat exchange bend 303 can work stably and normally. The bottom end of the heat exchange bend 303 passes through the top of the support plate 2, so that the air inside the heat exchange bend 303 can be discharged to the outside.

[0030] In addition, the heat exchange bend 303, the heat exchange fins 304 and the auxiliary heat exchange plates 305 can all be made of metals with strong heat exchange properties such as copper, which can achieve extremely strong heat exchange functions. The auxiliary heat exchange plates 305 are evenly distributed on both sides of the heat exchange bend 303. Through the neatly arranged auxiliary heat exchange plates 305, the air flow can flow normally around them, and at the same time, the contact area of ​​the heat exchange can be increased, thereby improving the efficiency of the heat exchange. The left and right sides of the air inlet box 306 are both opened to allow the outside air to enter normally.

[0031] At the same time, the top and bottom exhaust pipes 309 correspond to the positions of the top air inlet box 306 and the bottom air inlet box 306 respectively, so that the airflow can smoothly enter the interior of the exhaust pipe 309, and the bottom end of the top delivery pipe 310 is fixedly connected to the top of the return air pipe 311, and the bottom end of the bottom delivery pipe 310 passes through the top of the support plate 2 and is fixedly connected to the left side of the return air pipe 311, so that the gas inside the delivery pipe 310 can enter the interior of the baking oven body 1 through the return air pipe 311, wherein a fan can also be arranged on the outside of the return air pipe 311 to assist the entry of hot air flow.

[0032] In this embodiment, the filter assembly 500 is a structure for filtering waste residue and dust in furnace smoke.

[0033] like Figure 1 and Figure 3 As shown, the filter assembly 500 includes a main pipe 501 fixedly connected to the top of the baking oven body 1, and two limit plates 502 are fixedly connected to the inner right side wall of the main pipe 501. The top of the top limit plate 502 is slidably connected to the first dust filter net 503, and the top of the bottom limit plate 502 is slidably connected to the second dust filter net 504.

[0034] It should be noted that the bottom end of the main pipe 501 is fixedly connected to the top end of the docking pipe 302, so that the gas inside the main pipe 501 can enter the inside of the docking pipe 302, and the left sides of the first dust filter 503 and the second dust filter 504 are both on the left side of the main pipe 501 and are fixedly connected with a mounting plate, so that the first dust filter 503 and the second dust filter 504 can be taken out for cleaning or replacement after being used for a period of time. The mounting plate is connected to the left side of the main pipe 501 by screws, which can be easily installed and disassembled. The right side of the mounting plate fits with the left side of the main pipe 501 to play a sealing role, and a sealing gasket can be pasted on the right side of the mounting plate to improve the sealing effect.

[0035] The working principle of the above embodiment is:

[0036] When the brass metal parts are baked, the baking furnace body 1 is started, and the baking gas is transported to the inside of the baking furnace body 1 through the air inlet pipe 403. The brass metal parts are placed inside the placement pipe 402 for baking and heating. The hot air generated by the heating will naturally flow upward. During the flow of the hot air inside the main pipe 501, it is filtered and removed by the first dust filter 503 and the second dust filter 504 in turn, and then enters the inside of the heat exchange elbow 303 through the docking pipe 302, and finally is discharged through the bottom end of the heat exchange elbow 303, and the high temperature resistant fan 307 is started to allow the outside air to pass through the filter 307. 08 is filtered and enters the interior of the recovery box 301, and then through the cooperation between the heat exchange bend 303, the heat exchange fins 304 and the auxiliary heat exchange plates 305, the flowing air can efficiently exchange heat with the heat exchange bend 303, the heat exchange fins 304 and the auxiliary heat exchange plates 305. The heated air enters the interior of the delivery pipe 310 through the exhaust pipe 309, and is finally transported to the interior of the baking oven body 1 through the return air pipe 311. The pre-heated air will be heated to the baking temperature more quickly, thereby realizing the effect of utilizing the recovered waste heat to reduce the heating energy consumption of the baking oven body 1.

[0037] Compared with the prior art, the brass baking furnace with waste heat recovery can more fully and effectively recycle waste heat through the coordinated use of the recovery component 300 and the filter component 500 on the left side of the baking furnace body 1. The waste heat can be effectively recovered through efficient heat exchange, and the recovered waste heat can be transported back to the interior of the baking furnace for repeated use after treatment. At the same time, it can adapt to long-term continuous use, which not only reduces the loss of heat energy, but also indirectly reduces the workload of staff. It is very convenient and practical, and solves the problem that the existing baking device is prone to reduce the heat recovery efficiency and effect after long-term use.

[0038] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0039] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
