The structure of the automatic winding filter device
The structure of the automatic winding filter deviceThe automatic winding filter device is mainly composed of filter material, transmission system, and automatic control system, which work closely together to ensure the filter device's efficient operation.Filter material: As the core component of filtration, the filter material is like the "filter screen" of the device, which directly determines the effect and quality of filtration. It usually uses special cover filter materials, such as G3, and G4 (EN779) efficiency grade materials, these materials have good permeability and strong interception ability, and can effectively capture dust, particulate matter, and other impurities in the air. Filter materials of different materials and structures have differences in filtration efficiency, dust capacity, service life, and so on. For example, the filter material with fiber structure, the thickness and density of the fiber will affect the filtration effect of small particles; The mesh design enhances the strength and stability of the filter material, making it not easy to break during long-term use and extending the replacement cycle. Transmission system: The transmission system is the power source and mechanical actuator to achieve the replacement of filter material, mainly composed of motor, reducer, chain, sprocket filter material reel, and other components. The motor provides power, and the high-speed rotation of the motor is converted into a low-speed and high-torque rotation suitable for the winding of the filter material through the reducer, and then the transmission of the chain and sprocket drives the filter material scroll to rotate, to realize the operation of winding up the dirty filter material and replacing it with clean filter material. In this process, the precise coordination of the chain and sprocket ensures the smoothness and reliability of the transmission, avoids the problem of uneven winding of the filter material, and ensures the continuous and stable operation of the filter device. Automatic control system: The automatic control system is the "brain" of the entire filter device, which realizes real-time monitoring and accurate control of the operating state of the equipment through various sensors and controllers. Among them, the pressure difference sensor is one of the key components of the automatic control system, which can monitor the pressure difference before and after the filter in real-time. When the dusty air passes through the filter, the dust on the surface of the filter material gradually accumulates, the resistance of the filter increases, and the pressure difference rises accordingly. When the pressure difference reaches the set final resistance value, the pressure difference sensor transmits this signal to the controller. After receiving the signal, the controller immediately issues an instruction to start the motor of the transmission system and begin to replace the filter material; When the new clean filter material is replaced, the filter resistance is reduced, and the pressure difference is restored to the set lower limit value, the controller will control the motor to stop rotating and complete a filter material replacement process. In addition, the automatic control system also has a filter material alarm indicator function, when the whole volume of filter material is near to running out, the system will remind the operator to replace the filter material in time through the indicator light or alarm device to ensure the uninterrupted filtration work. |
