[0021] 3. Cylinder. Detailed Implementation

[0022] like Figures 1-4 As shown, this embodiment is achieved through the following technical solution: including: a gas distribution device 2 is connected to the gas blowing device 1 via a pipeline; the gas distribution device 2 is connected to the cylinder 3 via a pipeline.

[0023] Specifically, the blowing device 1 includes: the air inlet end of the blowing device (1) is connected to the air outlet end of the gas distribution device (2); the air inlet end of the gas distribution device (2) is connected to the cylinder (3) pipeline.

[0024] The air blowing device (1) includes a nozzle (101). A nozzle (104) is provided on one side of the nozzle (101), and a baffle (103) is hinged on the nozzle (101). A spring (1031) is connected between the nozzle (101) and the baffle (103). The baffle (103) abuts against the air outlet of the nozzle (104) under the pulling force of the spring (1031).

[0025] The nozzle (101) has a first interface (105) on one side, which is connected to the gas outlet of the gas distribution device (2).

[0026] Specifically, the spring 1031 is a tension spring. The spring 1031 applies a pulling force to the baffle 103, causing the baffle 103 to fit tightly against the opening of the nozzle 104. When the airflow flows out of the nozzle 104, the baffle 103 is pushed open by the air pressure, and the airflow flows out from the opening of the nozzle 104. Correspondingly, when the airflow is cut off, the baffle 103 returns to its original position under the action of the spring 1031, and the baffle 103 blocks the opening of the nozzle 104 to prevent dust from entering the nozzle 104 and causing blockage.

[0027] Specifically, the nozzle 104 is flat; the second interface 102 is a sealed pipe interface, and multiple different second interfaces 102 can be connected through pipes to realize the connection of multiple sets of air blowing devices 1.

[0028] Specifically, a sealing strip is provided between the contact surfaces of the baffle 103 and the nozzle 104. In this embodiment, the sealing strip is provided on the baffle 103 and abuts against the air outlet of the nozzle 104. The sealing strip improves the sealing performance of the baffle 103 to the opening of the nozzle 104.

[0029] Specifically, a plurality of baffles 1041 are evenly arranged inside the air outlet of the nozzle 104. The baffles 1041 divide the opening of the nozzle 104 into a plurality of small air outlets, making the airflow more uniform when it flows out of the nozzle 104. At the same time, the baffles 1041 obstruct the airflow and consume part of the energy of the airflow, thereby reducing the noise generated when the airflow passes through the nozzle 104.

[0030] Specifically, the gas distribution device 2 includes: a first valve group 201, an air bag 202, and a second valve group 203; the first valve group 201, the air bag 202, and the second valve group 203 are connected by pipelines.

[0031] Specifically, a safety valve is provided on the airbag 202. In this embodiment, the first valve group 201, the airbag 202, and the second valve group 203 are connected in sequence by pipelines. The first valve group 201 is connected to the cylinder 3, and the second valve group 203 is connected to the air blowing device 1. The opening pressure value set by the safety valve is less than the pressure limit of the airbag 202. When the pressure value of the airbag 202 reaches the opening pressure value of the safety valve, the gas is discharged from the airbag 202 through the safety valve to prevent the airbag 202 from being damaged due to excessive air pressure inside the airbag 202. The safety valve plays a protective role for the airbag 202.

[0032] The first valve group 201 is of the type of solenoid valve and check valve. In this embodiment, the check valve is divided into two positions. The check valve in the first position is connected in series with the main air circuit of the cylinder 3, and is referred to as the first check valve. The check valve in the second position is connected in series with the solenoid valve, and is referred to as the second check valve. The solenoid valve is connected in parallel with the main air circuit of the cylinder 3.

[0033] The solenoid valve is located at one end close to the cylinder 3, and the second one-way valve is located at one end close to the airbag 202. When air needs to be introduced into one side of the cylinder 3, the solenoid valve on the air intake side of the cylinder 3 is closed, and the pipeline for airflow into the airbag 202 is closed. Correspondingly, the airflow is supplied into the cylinder 3 through the main air passage of the cylinder 3 and the first one-way valve, thereby completing the action of the cylinder 3.

[0034] When one side of cylinder 3 needs to exhaust gas, the solenoid valve on the exhaust side of cylinder 3 opens. At this time, the first check valve blocks the main air passage of cylinder 3 to prevent the exhaust gas from flowing out along the main air passage of cylinder 3. Furthermore, the gas passes through the solenoid valve and the second check valve and enters the airbag 202 for storage. Further, excess gas is discharged through the safety valve on the airbag 202.

[0035] The second valve group 203 is a mechanical valve. When the second valve group 203 is opened, the gas in the air bag 202 flows into the air blowing device 1.

[0036] Usage: The gas discharged from cylinder 3 is temporarily stored in gas distribution device 2. Further, the gas in gas distribution device 2 is delivered to air blowing device 1 installed on electrolytic cell. Finally, air blowing device 1 blows away the dust on electrolytic cell.

[0037] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
