Description

Technical Field

[0001] The utility model relates to the technical field of brick kiln flues, in particular to a high-efficiency, energy-saving, circulating, movable brick kiln flue. Background Art

[0002] A brick kiln refers to a kiln for firing bricks, or a kiln for firing adobe into bricks and tiles. During the production process of a brick kiln, especially during the process of sintering hollow bricks with coal gangue, high-temperature flue gas needs to be discharged.

[0003] The brick kiln flues currently in use are mostly fixed in design, with simple smoke exhaust functions and lack of effective waste heat recovery capabilities. A large amount of heat energy is discharged into the environment in the form of flue gas, resulting in energy waste. At the same time, the direct discharge of dust mixed in the flue gas will pollute the environment.

[0004] Therefore, a high-efficiency, energy-saving, circulating and movable brick kiln flue is proposed. Utility Model Content

[0005] The utility model aims to provide a high-efficiency, energy-saving, circulating and movable brick kiln flue.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-efficiency, energy-saving, circulating, movable brick kiln flue, comprising: a flue main body, a telescopic connecting pipe fixedly connected to the top of the flue main body, a flue branch pipe fixedly connected to the top of the telescopic connecting pipe, and a rain shelter fixedly connected to the top of the flue branch pipe;

[0008] A heat recovery component is arranged in the flue main body, and the heat recovery component includes three second heat exchange tubes evenly arranged in the flue main body, the top ends of the three second heat exchange tubes extend to the top of the flue main body and are commonly connected to a circulating water pump, the bottom ends of the three second heat exchange tubes extend to the bottom of the flue main body and are commonly connected to a connecting pipe, and the bottom end of the connecting pipe is connected to the first heat exchange tube.

[0009] Preferably, one end of the first heat exchange tube away from the connecting tube is connected to the other end of the circulating water pump.

[0011] Preferably, the first heat exchange tube is installed at the air inlet of the brick kiln, and the flue main body is fixedly installed at the exhaust port of the brick kiln through a docking plate.

[0012] Preferably, the inner side of the telescopic connecting tube is made of aluminum foil, and the outer side of the telescopic connecting tube is made of silicone.

[0013] Preferably, a smoke filter assembly is also provided in the flue main body, and the smoke filter assembly includes a mounting groove opened in the flue main body, a filter frame is clamped in the mounting groove, a pull rod is fixedly connected to the outer side of the filter frame, and a filter net is provided on the inner side of the filter frame, and the filter net is made of fiber material.

[0014] Preferably, a limiting groove is provided on the side wall of the installation groove, a limiting pin matched with the limiting groove is provided on the inner wall of the filter frame, and the end of the limiting pin is designed as a small ball.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By setting up a heat energy recovery component, the high-temperature flue gas generated by the brick kiln can be discharged to the outside through the flue main body. During the high-temperature flue gas discharge process, the high-temperature flue gas can heat the heat-conducting liquid in the second heat exchange tube in the flue main body, which can increase the temperature of the heat-conducting liquid and recover the waste heat generated by the high-temperature flue gas. The heated heat-conducting liquid can be injected into the first heat exchange tube through a circulating water pump and a connecting pipe. The air entering the brick kiln can be preheated through the first heat exchange tube, which can improve the utilization rate of thermal energy. The heat-conducting liquid after heat exchange in the first heat exchange tube can enter the second heat exchange tube through a circulating water pump to continue heat exchange, which can ensure the heat exchange efficiency and is conducive to the continuous preheating of the air.

[0017] 2. By setting up the flue gas filter assembly, the filter on the filter frame can filter and absorb the dust in the flue gas, which can reduce the pollution of the flue gas to the environment. When the user pulls the filter frame outward through the pull rod, the limit pin on the filter frame can slide out of the limit groove, so that the user can take the filter frame out of the installation groove, which is convenient for cleaning the filter, and can avoid the filter being blocked, and can ensure the flue gas filtering effect. After the cleaned filter is inserted into the installation groove, the limit pin cooperates with the limit groove to fix the filter frame, which can improve the stability of the filter on the filter frame and is beneficial to the filtering of the flue gas.

[0028] See also Figure 2 One end of the first heat exchange tube 9 away from the connecting tube 10 is connected to the other end of the circulating water pump 7.

[0029] See also Figure 2 The first heat exchange tube 9, the second heat exchange tube 11 and the connecting tube 10 are all filled with heat transfer fluid.

[0031] See also Figure 1 The inner side of the telescopic connecting tube 4 is made of aluminum foil, and the outer side of the telescopic connecting tube 4 is made of silicone.

[0032] In the present embodiment, when in use, the high-temperature flue gas generated by the brick kiln can be discharged to the outside through the flue main body 1. During the high-temperature flue gas discharge process, the high-temperature flue gas can heat the heat-conducting liquid in the second heat exchange tube 11 in the flue main body 1, thereby increasing the temperature of the heat-conducting liquid and recovering the waste heat generated by the high-temperature flue gas. The heated heat-conducting liquid can be injected into the first heat exchange tube 9 through the circulating water pump 7 and the connecting tube 10. The air entering the brick kiln can be preheated through the first heat exchange tube 9, thereby improving the utilization rate of thermal energy. The heat-conducting liquid after heat exchange in the first heat exchange tube 9 can enter the second heat exchange tube 11 through the circulating water pump 7 to continue heat exchange, thereby ensuring the heat exchange efficiency and facilitating the continuous preheating of the air.

The air entering the brick kiln can be preheated through the first heat exchange tube 9, so as to improve the utilization rate of thermal energy, and the first heat exchange After heat exchange in tube 9, the heat transfer liquid can enter the second heat exchange tube 11 through the circulating water pump 7 to continue heat exchange, which can ensure the heat exchange efficiency and is beneficial to the continuous preheating of the air. During use, the filter screen 15 on the filter frame 2 can filter and adsorb dust in the flue gas, which can reduce the pollution of flue gas to the environment. When the user pulls the filter frame 2 outward through the pull rod 13, the limit pin 14 on the filter frame 2 can slide out of the limit groove 12, so that the user can take the filter frame 2 out of the installation groove 3, which is convenient for cleaning the filter screen 15 and can avoid the filter screen 15 from being blocked, which can ensure the flue gas filtering effect. After the cleaned filter screen 15 is inserted into the installation groove 3, the limit pin 14 cooperates with the limit groove 12 to fix the filter frame 2, which can improve the stability of the filter screen 15 on the filter frame 2 and is beneficial to the filtering of flue gas.
