Description

Technical Field

[0001] The present invention relates to the technical field of activated carbon adsorption, in particular to a self-cleaning rolling shutter door based on activated carbon adsorption. Background Art

[0002] Rolling shutters play a vital role in cleanroom industrial plants. These facilities are often used in industries with stringent cleanliness requirements, such as semiconductor manufacturing, pharmaceuticals, food processing, and precision instrument assembly. These facilities maintain strict control standards for airborne particulate matter and pollutant concentrations to ensure production quality and product purity. In modern industrial settings, multifunctional automatic rolling shutters are widely used as access control devices, offering advantages such as large opening space, convenient operation, and enhanced safety.

[0003] However, when the existing rolling shutter doors are used in dust-free factories with strict requirements on environmental cleanliness, it is not convenient for the rolling shutter doors to automatically clean the dust on the surface of the rolling shutter doors and simultaneously seal and collect the cleaned dust during the opening and closing process because of their relatively single cleaning function. On the other hand, the entrances and exits at different positions of the dust-free factory require air curtain machines or air shower rooms to be used in conjunction with the existing rolling shutter doors. The air curtain machines use airflow to block the entry of external airflow when the rolling shutter doors are opened and closed to prevent external airflow from carrying dust into the processing workshop. The air shower rooms use airflow to blow on objects after they enter, and simultaneously filter and collect dust in the air to prevent objects from carrying dust into the workshop. In response to the above problems, it is necessary to optimize the existing multi-functional rolling shutter doors to achieve sealed collection of clean objects, as well as how to achieve functions such as airflow walls and air purification.

The left and right ratchet groups 132 are opposite to the left and right blades in the column fan 12. The left and right sections of the column fan 12 are independent. The rack 133 is made of a deformable and retractable material. The outer side of the gear ring 131 is meshed with a rack 133. The rack 133 is fixed to the left and right sides of the rolling door 6. An adjustment box 14 is installed at the lower front side of the installation box 1. The adjustment box 14 is connected to the right slider 3 through the air outlet assembly 15. The air outlet assembly 15 includes an air outlet column 151. The air outlet column 151 is sealed and rotated inside the adjustment box 14. The outer convex end of the air outlet column 151 is the air outlet. The initial position of the air outlet on the outer side of the air outlet column 151 is tilted at a small angle. The air outlet column 151, The internal cavities of the regulating box 14 and the installation box 1 are connected to each other. A radar sensor is provided on the front side of the regulating box 14. A gear ring 152 is provided on the outer side of the shaft column on the right side of the air outlet column 151. A small section of teeth is distributed on the outer side of the gear ring 152. The small section of teeth on the outer side of the gear ring 152 is used for small-angle rotation of the air outlet column 151. The outer teeth of the gear ring 152 are meshed and connected with a rack 153. The rack 153 is installed at the bottom of the protrusion below the right fixed block 9. The cleaning component 10 is provided between the air intake plate 8 and the winding column 4. The cleaning component 10 is used to clean the surface of the rolling door 6; When the rolling shutter door 6 is rolled up, the rack 133 is synchronously driven to roll up, and the ratchet group 132 and the right section of the column fan 12 are driven to rotate through the right gear ring 131. The air in the inner cavity of the installation box 1 is blown into the regulating box 14 and the air outlet column 151 through the rotation of the column fan 12, and is blown out through the air outlet of the air outlet column 151 to blow objects that enter the detection range of the radar sensor, preventing external airflow or dust on the surface of objects from entering the rear of the rolling shutter door 6. At the same time, when the rolling shutter door 6 is rolled up on the rolling column 4, the rolled-up rolling shutter door 6 conflicts with the rear, and The slider 13 is driven forward by the winding column 4, and at the same time, the air intake plate 8 and the rolling shutter door 6 are slidably connected. As the rolling shutter door 6 in the winding state above moves, the air intake plate 8 and the fixed block 9 are driven to slide forward in the opening of the installation box 1. When the fixed block 9 moves, the rack 2 153 drives the gear ring 2 152 to rotate at a small angle. The small angle rotation of the gear ring 2 152 drives the air outlet column 151 to adjust its position at a small angle in the adjustment box 14, and causes the air outlet at the upper end of the air outlet column 151 to rotate backward to adjust the angle, so as to blow a swing wind on the front of the object entering the detection range of the radar sensor.

[0021] Working principle: When using the multifunctional door and window with a cleaning device, first, when a moving object enters the detection range of the radar sensor on the front side of the adjustment box 14, a signal is generated in the controller, and the motor 5 is turned on by the controller to drive the winding column 4 to rotate to reel the rolling door 6. During the reeling process of the rolling door 6, the concave and convex surface of the rolling door 6 changes, so that the positions of the contact strip 103, the second slider 102 and the roller 104 in the limiting slide groove 101 are adaptively adjusted by the spring, and the outer bristles of the two rollers 104 are always in contact with the front and rear surfaces of the rolling door 6. During the rotation of the winding column 4, the pulley 105 and the roller 104 are synchronously driven to rotate synchronously by the belt 106, and the front and rear surfaces of the rolling door 6 are cleaned by the brushes arranged outside the roller 104, and the cleaned dust falls into the air intake plate 8; When the rolling shutter door 6 is rolled up, the rack 133 is synchronously driven to roll up, and the right gear ring 131 is used to drive the ratchet group 132 and the right section of the column fan 12 to rotate. The column fan 12 rotates to blow the air in the inner cavity of the installation box 1 into the regulating box 14 and the air outlet column 151, and blown out through the air outlet of the air outlet column 151, blowing objects that enter the detection range of the radar sensor, preventing external air flow or dust on the surface of objects from entering the rear of the rolling shutter door 6. In this process, when the column fan 12 rotates to blow air, the air flow enters the air intake plate 8 through the air inlet at the rear of the air intake plate 8, and sucks the dust and cleaning materials in the air intake plate 8 into the activated carbon filter element 81 in the protruding square tube below the air intake plate 8, completing the collection of dust in the air intake plate 8, and at the same time filtering the air at the rear position of the rolling shutter door when opening and closing; In the above process, when the rolling shutter door 6 is rolled up on the rolling column 4, the rolled-up rolling shutter door 6 collides with the rear and drives the slider 1 3 to move forward through the rolling column 4. At the same time, the air intake plate 8 and the rolling shutter door 6 are slidably connected, and as the rolling shutter door 6 in the rolled-up state moves, the air intake plate 8 and the fixing block 9 are driven to slide forward in the opening of the installation box 1. When the fixing block 9 moves, the rack 2 153 drives the gear ring 2 152 to rotate at a small angle. The gear ring 2 152 rotates at a small angle and drives the air outlet column 151 to adjust its position at a small angle in the adjustment box 14, and causes the air outlet at the upper end of the air outlet column 151 to rotate backward to adjust the angle, so as to perform a swing wind blowing on the front of the object entering the detection range of the radar sensor to prevent the object from carrying dust into the production workshop; When the radar sensor detects that the object has reached the rolling shutter door 6, the controller turns on the motor 5 to reset the above-mentioned linkage parts, and drives the left gear ring 131 to rotate through the downward reset rolling shutter door 6 and the rack 133. The rotating left gear ring 131 drives the left section of the column fan 12 to rotate and blow air through the ratchet group 132, so that during the opening and closing process of the rolling shutter door 6, the air outlet on the air outlet column 151 continues to blow.
