Description

Technical Field

[0001] This utility model relates to the field of industrial gas preparation technology, specifically to a gas filter for industrial gas preparation. Background Technology

[0002] Industrial gases refer to gases widely used in industrial production and occupy an important position in the national economy. They are diverse and widely used. According to their uses and properties, they can be divided into fuel gases (such as hydrogen and acetylene, which are mainly used for combustion to generate energy), protective gases (such as nitrogen and argon, which play a protective role in welding, cutting and other processes), and process gases (such as oxygen, which plays a role in combustion in steelmaking).

[0003] The prior art discloses a simple gas filter for industrial gas preparation, with announcement number CN221155892U. The filter includes a filter box, a mounting shaft rotatably connected inside the filter box, and multiple buffer plates fixedly connected to the outer surface of the mounting shaft. An inlet coil is fixedly connected to the filter box. This simple gas filter for industrial gas preparation introduces high-pressure gas into an inlet pipe through the inlet coil, and then blows the gas out through multiple air nozzles on the inlet pipe. The gas first blows the buffer plates, causing them and the mounting shaft to rotate. Simultaneously, the buffer plates effectively buffer the incoming high-pressure gas. Then, the gas is thoroughly filtered through the cooperation of a first and second filter ring inside the filter box, greatly reducing the impact force on the filter plates, minimizing damage to the filter plates, and increasing the service life of the filter plates.

[0004] The filter box is fixedly connected to the intake coil tube. When replacing the intake coil tube, it is necessary to cut the intake coil tube and the filter box, which makes the replacement of the intake coil tube more troublesome and requires a lot of time to repair the intake coil tube.

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.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A gas filter for industrial gas preparation includes a filter device 1 and a filter housing 2. The left side surface of the filter housing 2 is threaded with two connecting pipes 3. The two connecting pipes 3 are arranged vertically, with the upper connecting pipe 3 being the inlet pipe and the lower connecting pipe 3 being the outlet pipe. The filter device 1 is installed inside the filter housing 2.

[0030] The filtration device 1 includes a drive motor 11, a stirring plate 12, a spray assembly 13, and a connecting frame 14. The connecting frame 14 is installed on the bottom surface of the drive motor 11, the stirring plate 12 is threaded to the bottom surface of the rotor of the drive motor 11, and the drive motor 11 is installed on the top of the spray assembly 13.

[0031] The spray assembly 13 includes a spray unit and a support unit, which are arranged sequentially from top to bottom.

[0032] The spray unit includes a spray pipe 131, a connecting pipe 133 fixedly connected to the top of the spray pipe 131, a transport pipe 132 fixedly connected to the top of the connecting pipe 133, a limit cover 134 slidably connected to the top of the spray pipe 131, the limit cover 134 and the filter housing 2 are connected by a threaded rod, the limit cover 134 and the filter housing 2 are threadedly connected, which facilitates the disassembly and replacement of the limit cover 134 and can increase the service life of the limit cover 134. The connecting frame 14 is installed at the bottom of the limit cover 134. The connecting frame 14 and the limit cover 134 can limit the drive motor 11, which facilitates the disassembly and replacement of the drive motor 11 and can increase the service life of the drive motor 11.

[0033] The support unit includes a support frame 136, which is movably connected to the bottom of the spray pipe 131. A filter screen is installed on the top of the support frame 136. The support frame 136 supports the spray pipe 131, preventing it from shaking and protecting its safety, thus increasing its service life. The support frame 136 is fixedly connected to the top surface of the sealing cover 138. The stirring plate 12 is rotatably connected to the middle of the sealing cover 138 and the middle position of the limiting cover 134. The sealing cover 138 and the limiting cover 134 limit the position of the stirring plate 12. A metal plate 135 is movably connected to the bottom surface of the cover plate 138. The metal plate 135 is inserted into the bottom of the filter housing 2. The sealing cover plate 138 is also inserted into the bottom of the filter housing 2. The metal plate 135 and the sealing cover plate 138 are inserted into the bottom of the filter housing 2, thereby sealing the bottom of the filter housing 2 and preventing the industrial gas inside the filter housing 2 from escaping. A threaded rod 137 is fixedly connected to the bottom of the metal plate 135. The threaded rod 137 is inserted into the bottom of the filter housing 2. The metal plate 135 and the threaded rod 137 are inserted into the bottom of the filter housing 2, thereby limiting the metal plate 135 and preventing it from falling off the bottom of the filter housing 2.

[0034] In use, the two pipes at the upper end of the connecting pipe 2 3 are connected, and the upper connecting pipe 2 3 can input industrial gas into the interior of the filter housing 2.

[0035] The chemical liquid enters the interior of the spray pipe 131 through the transport pipe 132 and the connecting pipe 133. The spray pipe 131 can perform spraying operations inside the filter housing 2. The sprayed chemical liquid mixes with the industrial gas inside the filter housing 2. The reagent reacts with the hazardous gas in the industrial gas, which can filter the hazardous gas in the industrial gas.

[0036] Next, the drive motor 11 is started. The rotor of the drive motor 11 drives the stirring plate 12 to rotate. The stirring plate 12 rotates inside the filter housing 2. The stirring plate 12 can stir and mix the liquid and gas inside the filter housing 2, making gas filtration more convenient and faster. A filter screen is provided on the top of the support frame 136. The filter screen can filter industrial gas and maintain the cleanliness of industrial gas.

[0037] The filtered gas can be discharged through the connecting pipe 23 below.

[0038] Rotate the nut, and the nut rotates on the surface of the threaded rod 137. The connection between the limiting cover plate 134 and the filter housing 2 becomes loose. Pull the limiting cover plate 134 downward and move it downward along the surface of the stirring plate 12, so that the limiting cover plate 134 can be separated from the filter housing 2.

[0039] At this point, grasp the bottom surface of the sealing cover 138 and pull the sealing cover 138 downward. The sealing cover 138 moves downward along the inner wall surface of the filter housing 2. The sealing cover 138 can drive the support frame 136 to move downward, so that the support frame 136 is separated from the spray pipe 131, and the connection between the spray pipe 131 and the limiting cover 134 is loosened.

[0040] Rotate the nut, and the nut will rotate on the threaded rod surface at the top of the filter housing 2, so that the connection between the limiting cover plate 134 and the filter housing 2 is loosened, and the limiting cover plate 134 is pulled upward, so that the limiting cover plate 134 can drive the spray pipe 131, the connecting pipe 133 and the transport pipe 132 to move upward.

[0041] The limiting cover 134 can drive the drive motor 11 and the stirring plate 12 to move upward, which facilitates the maintenance of the drive motor 11, stirring plate 12, spray pipe 131, transport pipe 132 and connecting pipe 133, and can increase the service life of the device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
