Description

Technical Field

[0001] The present invention relates to the technical field of dust prevention between equipment rooms, and in particular to an intelligent dust prevention and filtering device between electronic equipment rooms. Background Art

[0002] Currently, the dust prevention method for industrial electronic rooms mainly focuses on traditional leak point sealing, and physical sealing alone cannot achieve good results.

[0003] The technical background of the micro-positive pressure fresh air system stems from concerns about indoor air quality. Through intelligent control, it continuously generates a micro-positive pressure within the space, preventing dust from entering the area. The micro-positive pressure fresh air system uses a high-pressure, high-flow fan to mechanically deliver air from one side to the room, increasing the indoor air pressure to a level higher than that outside. This forces a fresh air flow field within the system. During the air supply, the air entering the room is filtered and preheated in winter to ensure the quality of the air entering the room. Therefore, this solution proposes an intelligent dust-proof filtration device for electronic equipment rooms. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide an intelligent dust-proof filtering device for electronic equipment rooms. Through the diversion box arranged in the main control unit, the air flowing through the interior is switched by using a flap to switch the output direction, so that the air flow directions of the top control main unit, the top control sub-unit and the bottom control main unit, the bottom control sub-unit are reversed. When the purified and electrically heated hot air is transported to the room, a bottom-exhaust and top-suction mode is implemented, and the hot air spreads from the bottom to the top of the entire room and is discharged from the top control main unit and the top control sub-unit. When in normal use, the flap is also switched to enable the purified air to be discharged from the top and sucked from the bottom. The cooler air spreads from top to bottom throughout the equipment room and is then discharged from the bottom control main unit and the bottom control sub-unit. The indoor air pressure monitoring module and the outdoor air pressure monitoring module are respectively set in the four groups of units inside the equipment room to realize real-time monitoring of the internal and external air pressure, thereby effectively regulating the size of the incoming air volume to ensure that the room is in a slightly positive pressure state. The filter elements are respectively set in the four groups of units in the room, and they can all be flipped by a stepper motor, so that when switching the intake and exhaust modes, the filter element can be flipped to maintain effective filtration, and this mechanism uses the automatic telescopic function when replacing the filter element, which makes the operation convenient, time-saving and labor-saving.

[0030] Working principle: When in use, the air at the tail is sucked into the filter chamber 113 for filtration by opening the internal fan chamber 110 of the main control unit 1. The filtered gas is selectively heated by the heating chamber 121. During heating, the downwind solenoid valve 126 is actively closed, and the first solenoid valve 124 and the second solenoid valve 128 are opened, and the purified air is respectively introduced into the first electric heating box 125 and the second electric heating box 129 for heating and then returns to the main downwind duct 122 and enters the inside of the diverter box 132. When the air is being heated, the first stepper motor 137 in the diverter box 132 drives the flap 14 to rotate. 2 rotates, causing the air in the diversion box 132 to enter through the diversion guide groove 1 138 and then flow out through the diversion guide groove 2 139. The air then flows along the silencer duct to the bottom control main unit 4 in the equipment room. The air is then directed to the other bottom control sub-units 5 through the bottom control main air box 401. According to the air volume, the staggered gap between the movable grille 213 and the first air control plate 204 is adjusted to ensure a balanced air volume at each air outlet. The air is filtered by the filter elements in the bottom control main unit 4 and the bottom control sub-unit 5 and then flows into the equipment room. It should be noted that the front faces of the filter elements in the bottom control main unit 4 and the bottom control sub-unit 5 are facing inward at this time, that is, the fluid flows through this side of the filter element first. The hot air flows from bottom to top in the room, and through the micro-positive pressure effect (the indoor air pressure is greater than the normal outdoor air pressure), the air is discharged from the top control main unit 2 and the top control sub-unit 3. Note that at this time, the front of the filter element in the top control main unit 2 and the top control sub-unit 3 is facing the equipment room. The air discharged after filtration enters the diversion guide groove four 141 of the diversion box 132 and is discharged from the diversion guide groove three 140.

[0031] When air at normal temperature is introduced into the room, the downwind solenoid valve 126 is actively opened, while the first solenoid valve 124 and the second solenoid valve 128 are closed. The first stepper motor 137 drives the flap 142 to rotate. At this time, the purified air enters the diversion guide groove 1 138 in the diversion box 132 and flows out from the diversion guide groove 4 141. At this time, the electric telescopic rod 1 207 in the top control main unit 2 works, and the first filter element bracket 210 and the top control main filter element 211 are synchronously pushed out from the top control main connecting seat 205. After being pushed out, the second stepper motor 209 drives the first filter element bracket. After 210 rotates 180°, the electric telescopic rod 207 returns to its original position, and the top control sub-unit 3 acts in the same way to change the direction of the filter element so that the front side faces inward, that is, the fluid flows through this side of the filter element first. At the same time, the electric telescopic rod 3 405 in the bottom control main unit 4 works to push the third filter element bracket 407 together with the bottom control main filter element 408 out of the bottom control main connecting seat 403. After being pushed out, the third filter element bracket 407 is driven by the fourth stepper motor 410 to rotate 180°. After that, the electric telescopic rod 3 405 returns to its original position, and the bottom control sub-unit 5 acts in the same way to change the direction of the filter element so that the front side of the filter element faces the equipment room.
