[0014] 1. Equipped with an automatic pressure stabilization component, this equipment uses a PLC controller as its external controller. The PLC controller collects the analog signal from the second pressure transmitter of the external air tank to obtain the current pressure value of the external air tank. The required pressure for the four air supply pipes is set, and the PLC programming calculates the analog setpoint value for the proportional opening of the electric regulating valve.

[0031] The inner ring of the outer blower ring 1 is equipped with an air supply cleaning component 3, which includes an air supply hole 301, a C-shaped limit box 302, a gear ring 303, a cleaning box 304, a cleaning hole 305, a cleaning block 306, a compression spring 307, a gear box 308, a drive motor 309, and a drive gear 310.

[0033] The working principle and usage process of this utility model are as follows: The external controller of this equipment is a PLC controller. The PLC controller collects the analog signal from the second pressure transmitter 205 of the external air tank 204 to obtain the current pressure value of the external air tank 204.

The PLC analog output module outputs the control of the electric regulating valve 206. The electric regulating valve 206 controls the opening according to the magnitude of the analog value. Then, the signal from the first pressure transmitter 203 of each air supply pipe 201 is transmitted to the PLC controller to obtain the actual pressure value of each branch pipe. The pressure difference between the set pressure and the actual pressure is calculated by programming to increase or decrease the analog value of the electric regulating valve 206 to achieve linear control and stabilize the pressure. After the improvement, the quality of the outer wall of the pipe can be improved, and the problem of high zinc consumption caused by excessive zinc layer on the surface can be controlled. Personnel no longer need to manually adjust the valve, reducing labor intensity.

The positioning screws 210 are tightened to fix the air supply pipe 201. This is to prevent the air supply pipe 201 from shaking during the air supply process, which could cause the connection to loosen and leak air, thus improving safety.

[0035] Furthermore, during use, if debris is found embedded in the air outlet 301 causing uneven airflow, the drive motor 309 is turned on. The drive motor 309 drives the cleaning box 304 to make circular motion through the drive gear 310 and the gear ring 303. During this process, the compression spring 307 pushes the cleaning block 306 to slide along the cleaning hole 305 and squeeze the air outlet 301 of the outer blower ring 1 to remove debris. The rotating cleaning box 304 makes the airflow more uniform and improves the stability of the airflow.
