[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An energy-saving device for oxygen enrichment in a double-chamber lime kiln is shown in the embodiment of this utility model, comprising: a shell 1, an electric door 2 movably installed on the front side of the shell 1, a controller 3 installed on the electric door 2, an oxygen enrichment generator 8 installed in the inner cavity of the shell 1, a connecting pipe 17 connected to the rear side of the oxygen enrichment generator 8, and a partition 16 provided on the rear side of the oxygen enrichment generator 8, the partition 16 being fixedly installed in the inner cavity of the shell 1, the front side of the partition 16 being an oxygen collection chamber 20, and the rear side of the partition 16 being an oxygen enrichment chamber 19, the oxygen enrichment generator 8 being located in the inner cavity of the oxygen collection chamber 20, the connecting pipe 17 penetrating the partition 16 and extending into the inner cavity of the oxygen enrichment chamber 19, two oxygen enrichment transmission pipes 18 being inserted and installed on the rear side of the shell 1, one end of the oxygen enrichment transmission pipes 18 extending into the inner cavity of the oxygen enrichment chamber 19, and ventilation components being provided on both the left and right sides of the outer wall of the shell 1.

[0030] During use, two ventilation components are used to allow air exchange between the oxygen collection chamber 20 inside the outer casing 1 and the outside air. At the same time, the oxygen generator 8 generates oxygen inside the oxygen collection chamber 20. The oxygen enters the oxygen enrichment chamber 19 through the connecting pipe 17, and then enters the two chambers of the double-chamber lime kiln through the two oxygen enrichment transmission pipes 18. By using oxygen enrichment to assist combustion, it can effectively reduce the consumption of flame-retardant air, reduce the channel pressure, increase the maximum production capacity, reduce the power consumption, reduce the amount of exhaust gas emissions, reduce heat loss, improve the thermal effect, and reduce the consumption of fuel gas.

[0031] In this embodiment, as Figures 4-5 As shown; the ventilation component includes two mounting frames 5, and ventilation slots 6 are provided on both the left and right sides of the outer wall of the outer shell 1. The two mounting frames 5 are respectively movably installed in the inner cavity of the corresponding ventilation slots 6, and ventilation filters 9 are fixedly installed in the inner cavity of both mounting frames 5.

[0032] In use, the ventilation slot 6 and the ventilation filter 9 work together to enable air exchange between the oxygen collection chamber 20 and the outside air, and to filter the exchanged air to prevent air containing fixed impurities from hindering the subsequent operation of the oxygen generator 8.

[0033] In this embodiment, as Figure 5 As shown; the ventilation assembly also includes multiple movable limiting blocks 13. Multiple grooves 12 are provided on opposite sides of the two mounting frames 5. The movable limiting blocks 13 are located in the inner cavity of the corresponding grooves 12, and a round shaft 14 is rotatably connected to the movable limiting blocks 13. The round shaft 14 is fixedly installed on the inner wall of the groove 12, and one side of the movable limiting block 13 is in contact with the inner wall of the outer shell 1.

[0034] During use, multiple movable limit blocks 13 are used to limit the movement between the mounting frame 5 and the inner wall of the outer shell 1, ensuring the stability of the mounting frame 5 and other components during installation.

[0035] In this embodiment, as Figure 5As shown; an anti-slip pad 15 is fixedly installed on the outer wall of the movable limiting block 13, and the anti-slip pad 15 is in contact with the inner wall of the outer shell 1.

[0036] In use, the multiple anti-slip pads 15 are used to increase the friction between the outer wall of the movable limit block 13 and the inner wall of the outer shell 1.

[0037] In this embodiment, as Figures 4-5 As shown; multiple slots 7 are provided on the outer wall of the ventilation slot 6, and multiple blocks 10 are fixedly installed on the outer wall of the mounting frame 5. The blocks 10 are inserted into the inner cavity of the corresponding slots 7.

[0038] In use, the insertion of multiple locking blocks 10 into the locking slots 7 achieves the limiting of the outer side of the mounting frame 5 and the outer wall of the outer shell 1. In conjunction with multiple movable limiting blocks 13, the mounting frame 5 and the inner and outer sides of the outer shell 1 are simultaneously limited, ensuring that the mounting frame 5 can be stably installed inside the ventilation slot 6. When disassembling, simply rotate the movable limiting block 13 around the circular axis 14 so that the movable limiting block 13 is embedded in the corresponding groove 12, and the mounting frame 5 can be pulled out from inside the ventilation slot 6 to achieve disassembly. This facilitates the subsequent cleaning of components such as the ventilation filter 9 and ensures the ventilation effect.

[0039] In this embodiment, as Figure 5 As shown; handles 11 are fixedly installed on the outer walls of multiple card blocks 10, and the handles 11 are cylindrical.

[0040] When in use, the multiple handles 11 make it easier for workers to apply force to the installation frame 5, facilitating disassembly.

[0041] In this embodiment, as Figures 1-3 As shown; the controller 3 is electrically connected to the electric door 2 and the oxygen-enriched generator 8 respectively.

[0042] In use, the above settings enable the controller 3 to control the opening and closing of the electric door 2 and the oxygen-enriched generator 8, making operation convenient.

[0043] In this embodiment, as Figures 1-3 As shown; pulleys 4 are fixedly installed at the bottom of the outer casing 1 near the four corners.

[0044] When in use, the combined use of multiple pulleys 4 allows the entire device to be moved easily, changing its working position and ensuring that the device is used in a well-ventilated environment.
