[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1

[0023] Please see Figures 1-3 An oxygen generating device includes a casing 1, an oxygen generating unit 2, and a gas conveying unit 3. The casing 1 has an oxygen generating zone 11 and an oxygen storage zone 12 arranged at intervals. The oxygen generating unit 2 is located in the oxygen generating zone 11 and is used to generate oxygen. The gas conveying unit 3 is located in the oxygen storage zone 12 and is used to store and output oxygen. The oxygen generating unit 2 includes an oxygen generator 21 and a blower 22. The oxygen generator 21 and the blower 22 are connected by pipes. The blower 22 is used to draw outside air into the oxygen generator 21. The oxygen generator 21 and the gas conveying unit 3 are connected through a transfer pipe 101. The gas conveying unit 3 is connected to an external boiler.

[0024] The oxygen generating equipment in this embodiment is an integrated design. The casing 1 has an oxygen generating area 11 and an oxygen storage area 12 arranged at intervals and connected, which respectively accommodate the oxygen generating unit 2 and the gas conveying unit 3, effectively reducing the footprint of the equipment. At the same time, the blower 22 of the oxygen generating unit 2 continuously provides outside air to the oxygen generator 21. Then, the oxygen generator 21 separates and filters the outside air and transfers the oxygen to the gas conveying unit 3 through the transfer pipe 101 before outputting it, thereby obtaining oxygen and inputting it into the boiler. This effectively increases the combustion efficiency of fuel, reduces energy consumption, and avoids environmental pollution caused by incomplete combustion.

[0025] In a preferred embodiment, the oxygen generator 21 includes a sealed box 211 and eight molecular sieve cylinders 212; the sealed box 211 is disposed within the oxygen generation zone 11; the output end of the blower 22 is connected to the sealed box 211; the sealed box 211 has eight mounting positions 200; each of the eight mounting positions 200 corresponds one-to-one with one of the eight molecular sieve cylinders 212, and the molecular sieve cylinders 212 are detachably disposed within the corresponding mounting position 200; the output ends of each of the eight molecular sieve cylinders 212 are connected to the transfer pipe 101 via branch pipes (not marked in the figure). Specifically, the sealed box 211 is a hollow hexahedron with a through hole on its upper surface to form the mounting position 200. The molecular sieve cylinder 212 passes through the through hole and is arranged inside the sealed box 211. One side of the sealed box 211 has an air vent connected to the output end of the blower 22, thereby continuously supplying air into the sealed box 211 through the blower 22, increasing the pressure inside the sealed box 211, and causing air to continuously enter the molecular sieve cylinder 212. Under the action of the molecular sieve cylinder 212, only oxygen can pass through the output end of the molecular sieve cylinder 212 and be transported to the transfer pipe 101, thereby achieving the effect of oxygenation. The specific structure of the molecular sieve cylinder 212 is a commonly used technique in the art, such as the molecular sieve cylinder disclosed in CN202010495U and the molecular sieve cylinder assembly disclosed in CN216677627U; therefore, this embodiment will not elaborate further on it.

[0026] As a further preferred embodiment, the oxygen generator 21 further includes eight flow meters 213; each of the eight flow meters 213 corresponds one-to-one with one of the eight molecular sieve cylinders 212, and the output end of each molecular sieve cylinder 212 is connected to the corresponding flow meter 213; the output ends of each of the eight flow meters 213 are connected to the transfer pipe 101. In this preferred embodiment, the amount of oxygen per unit time can be obtained through the flow meters 213, thereby monitoring the working status of the molecular sieve cylinders 212, and allowing for timely adjustment or replacement of the molecular sieve cylinders 212.

[0027] In this embodiment, a filter 102 is provided on the transfer pipe 101 to further purify the gas entering the boiler. In practical applications, the filter 102 is located between the oxygen generation unit 2 and the gas delivery unit 3. With this design, the filter 102 effectively prevents external dust from entering the boiler. The filter 102 is an air filter 102, and this embodiment does not limit the type of filter 102. Therefore, those skilled in the art can also use conventional filters 102 within the scope of this embodiment.

[0028] In this embodiment, specifically, the gas delivery unit 3 includes a vacuum pump 31 and a storage tank 32 disposed within the oxygen storage zone 12; the input end of the vacuum pump 31 is connected to the transfer pipe 101, and the output end of the vacuum pump 31 is connected to the storage tank 32; the output end of the storage tank 32 is used to connect to an external boiler pipe. Under the above design, the vacuum pump 31 continuously obtains oxygen generated by the molecular sieve cylinder 212 through the transfer pipe 101 and delivers it to the storage tank 32. Then, the oxygen is output through the output end of the storage tank 32 to the combustion chamber of the external boiler, thereby increasing fuel combustion efficiency, reducing energy consumption, and avoiding environmental pollution caused by incomplete combustion. It should be noted that in other embodiments, a pressure valve and a switching valve are provided on the pipe at the output end of the storage tank 32 to control whether oxygen is delivered and to adjust the oxygen output according to usage conditions.

[0029] Of course, in practical applications, this equipment also includes a PLC control unit 4; the PLC control unit 4 is used to control the oxygen generating unit 2 and the gas delivery unit 3. In this embodiment, the working process of the oxygen generating equipment is as follows: the blower 22 draws in outside air into the closed box 211 of the oxygen generator 21, and separates the oxygen from the air through multiple molecular sieve cylinders 212 inside. Then, under the action of the vacuum pump 31, the obtained oxygen is delivered to the storage tank 32 of the gas delivery unit 3. When the external boiler needs oxygen supply, the PLC control unit 4 opens the corresponding valve to output oxygen to the combustion chamber of the external boiler. As for how the PLC control unit 4 specifically controls the oxygen supply, this is a technical method commonly used by those skilled in the art, so it will not be explained in detail.

[0030] In a preferred embodiment, the oxygen storage area 12 of the casing 1 is further provided with a gas outlet 100; the output end of the storage tank 32 is connected to the gas outlet 100 via a pipe. Under the above design, the external boiler is connected to the gas outlet 100 via a flange, which not only facilitates connection but also effectively improves the stability of the connection.

[0031] To enable the blower 22 to draw in outside air, the housing 1 is provided with an air inlet 110; the air inlet 110 is connected to the outside. In this embodiment, specifically, the air inlet 110 is a grille and includes multiple grilles. In other embodiments, to allow outside dust to enter the device, a filter screen is also provided on the grille.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
