[0030] The embodiment provides a paper machine ventilation device with air purification function, aiming to improve the air quality in the working environment of the paper machine, improve the production efficiency through the efficient air purification and ventilation system, and reduce the influence of pollutants on the equipment. The device includes a plurality of main components, such as a ventilation device body, an air inlet channel, a filter screen, an electrostatic generator, a dust collecting electrode column, a discharge electrode column, a power supply motor, a fan blade disc, a transmission shaft and the like. Each component works cooperatively through reasonable cooperation to ensure efficient operation of the device.

[0031] Ventilation device body: The ventilation device body serves as the support structure of the device, bearing all other components. Its main function is to provide a structural platform to ensure the stable installation of other components and to make the air flow system smooth. The side of the ventilation device body is provided with an air outlet, through which the air flow can be quickly discharged to achieve the effect of efficient ventilation.

[0032] Air inlet channel: The air inlet channel is located at the front end of the ventilation device body, and its function is to guide air into the ventilation device. A filter screen is arranged at the front end of the air inlet channel for preliminary filtering of large dust particles in the air to prevent these particles from entering the subsequent purification link. The filter screen is connected and fixed through the air inlet channel to ensure that the air flow first passes through the primary filter when entering the device.

[0033] Filter screen: The filter screen is located at the front end of the air inlet channel, and its main function is to remove large dust particles, fibers or other larger substances in the air to ensure the normal operation of the subsequent purification link. The design of the filter screen can prevent larger dust particles from directly entering the electrostatic purification system, avoiding affecting the purification efficiency.

[0034] Electrostatic generator and electrode column: The electrostatic generator, dust collecting electrode column and discharge electrode column are arranged at the rear end of the filter screen. The electrostatic generator generates static electricity through an electric field, and the dust collecting electrode column and the discharge electrode column form an electric field for adsorbing fine particles in the air. Fine particles are adsorbed onto the dust collecting electrode column through the electric field, further cleaning the air. This design enhances the air purification capacity through the electric field, which is more effective in removing fine particles than pure mechanical filtration.

[0035] Power supply motor and fan blade disc: The power supply motor is located at the lower end of the ventilation device body and drives the fan blade disc to rotate through the belt and transmission shaft. The fan blades are arranged on the front surface of the fan blade disc, which are designed in an integrated manner with the fan blade disc for generating wind power to push the air flow. The rotation of the fan blade disc drives the air flow into the air inlet channel, which is then discharged from the air outlet after passing through the filter screen and the electrostatic purification system. The power supply motor is connected to the power supply through wires to provide continuous power support.

[0036] Transmission shaft and transmission connecting disc: The transmission shaft connects the power supply motor and the fan disc. The motor drives the transmission shaft to rotate through the transmission connecting disc, thereby driving the rotation of the fan disc. Through the transmission of the belt, the rotation transmission efficiency between the power supply motor and the fan disc is improved. This design ensures that the fan disc can run continuously and stably, improving the air circulation effect.

[0037] Base: The base is located at the lower end of the ventilation device main body, providing support and stability. The base is connected to the ventilation device main body through fixing bolts, ensuring the stability of the entire device structure and preventing displacement. The power supply motor is installed on the base, and the motor is fixed on the base through fixing bolts, ensuring the transmission efficiency between the motor and the fan disc. At the same time, the integrated design of the base and the ventilation device main body simplifies the structure of the device, improves its stability and shock resistance.

[0038] Component cooperation logic: During the operation of the equipment, the power supply motor provides power through the wire to drive the rotation of the fan disc. The rotation of the fan disc generates wind power, and the air enters the air inlet channel, first passing through the filter screen to remove large particles of dust. Then, under the action of the electric field of the electrostatic generator and the electrode column, fine particles are adsorbed onto the dust collecting electrode column, thereby realizing air purification. The purified air is discharged through the air outlet on the side of the ventilation device main body. This process works through the cooperation of mechanical and electrostatic double filtration systems to achieve efficient air purification.

[0039] When the filter screen in the air inlet channel accumulates too much dust, the equipment can solve the problem by quickly replacing the entire purification structure. The design of this device makes cleaning and replacement work more convenient and efficient, without affecting the normal work of the paper machine. The replaceable design of this structure effectively saves cleaning time and reduces the impact of equipment maintenance on production.

[0040] Summary: The paper machine ventilation device with air purification function in this embodiment realizes efficient filtration and purification of air through reasonable component cooperation and cooperation. The combination of filter screen, electrostatic generator, dust collecting electrode column and discharge electrode column ensures the double filtration of large particles and fine particles in the air, improving air quality. The fan disc driven by the power supply motor ensures the stability and efficiency of air circulation. The overall structure is simple and convenient to maintain, which can significantly improve the working environment quality of the paper machine and reduce the impact of pollution on the equipment.
