The filter cartridge 200 of the present application is provided therein with a blowing plate 220, and the blowing plate 220 is used to clean dust on the surface of the filter cartridge 210. The second ventilation pipe 204 and the filter element 210 are positioned in the middle of the two air inlets 203, the filter element 210 divides the filter cartridge 200 into two spaces distributed left and right, the two air inlets 203 are respectively positioned below the two spaces, and in normal operation, the two air inlets 203 are simultaneously used for air inlet, and air passes through the filter element 210, enters the dryer 205 from the air outlet 201, and finally enters the communication cabinet 100. Because in the high humidity air environment, the water content in the gas is great, along with the continuous entering of air in cartridge 200, the humidity in cartridge 200 rises gradually, the humidity in cartridge 200 rises and helps improving the filtration efficiency of filter element 210, the dust in the air can be better adsorbed to the adhesion moisture on the filter element 210, be provided with humidity detector (not shown in the figure) on the air blast plate 220, when the humidity in cartridge 200 reaches the preset value (the preset value refers to when air blast plate 220 cleans filter element 210, can effectively reduce the required air humidity value of dust), just start cleaning filter element 210, during the cleaning, the humidity in cartridge 200 is higher, can effectively reduce the dust that produces in the cleaning process.
The air blowing plate 220 moves towards the direction close to the filter element 210, as shown in fig. 8 to 12, the air blowing plate 220 moves to a cleaning position close to the filter element 210, the air blowing plate 220 shields the air inlet 203 on the left side, so as to ensure the cooling effect of the communication cabinet 100, namely, to ensure the normal heat dissipation of the cabinet, the air inlet 203 on the right side is increased, so that the left side of the filter element 210 starts to be cleaned, and the right side still works, and the heat dissipation failure of the communication cabinet 100 caused by cleaning of the filter element 210 is avoided.
Specifically, as shown in fig. 10, a rotating groove 221 is formed on a side end of the air blowing plate 220, rotating grooves 221 are formed on two side ends of the air blowing plate 220 in this embodiment, a return pipe 230 is disposed in each of the two rotating grooves 221, an air vent 231 is formed on a side wall of the return pipe 230, and an air passage 222 is formed on a side wall of the rotating groove 221, as shown in fig. 5, the air passages 222 are distributed along a transverse direction of the air blowing plate 220, the air passages 222 are communicated with the rotating grooves 221, a plurality of air blowing holes 223 are formed on one surface of the air blowing plate 220, which is close to the filter element 210, the air blowing holes 223 are communicated with the air passages 222, and an opening size of the air passages 222 is the same as an opening size of the air vent 231. When the filter element 210 is not cleaned, the vent hole 231 of the return pipe 230 and the opening of the air passage 222 are staggered, and no air exists in the air blowing hole 223; when the filter element 210 needs to be cleaned, the return pipe 230 rotates to enable the vent hole 231 and the opening of the air passage 222 to have an overlapping area, and the air introduced into the return pipe 230 can enter the air passage 222 through the overlapping area and then be blown from the air passage 222 to the filter element 210 through the air blowing hole 223, so as to complete the function of cleaning the filter element 210.
When the overlapping area of the vent hole 231 and the opening of the air duct 222 is larger, the amount of air blown by the air blowing hole 223 increases, and the force for cleaning the filter element 210 can be increased.
Specifically, the blowing plate 220 is provided with a rotating assembly 300, the rotating assembly 300 is used for driving the return pipe 230 to rotate, the rotating assembly 300 comprises a gear sleeve 310 and a rack 320, the gear sleeve 310 is fixedly sleeved on the periphery of the top end of the return pipe 230, the rack 320 is slidably arranged on the blowing plate 220, a guide groove 251 is arranged at the side end of the blowing plate 220, the rack 320 is positioned in the guide groove 251, a pressure spring 330 is arranged in the guide groove 251, the pressure spring 330 is used for resetting the rack 320, the rack 320 is meshed with the gear sleeve 310, the rack 320 drives the gear sleeve 310 to rotate when sliding so as to drive the return pipe 230 to rotate to adjust the superposition area of the vent hole 231 of the return pipe 230 and the opening of the air passage 222, and it can be understood that when the filter element 210 is closer to the blowing plate 220, the limiting plate 212 pushes the rack 320 to move more, the rotation angle of the return pipe 230 is larger, and the blowing amount of the blowing hole 223 is increased.
As shown in fig. 8, the filter element 210 can move left and right in the filter cartridge 200 to push the rack 320, thereby realizing the function of adjusting the overlapping region. The bottom of filter core 210 is provided with rectangular protruding 211, and rectangular protruding 211's left and right ends are provided with elastic component (not shown in the figure), and cartridge filter 200 bottom is provided with rotor plate 240, and runner 241 has been seted up to rotor plate 240's up end, and rectangular protruding 211 is located runner 241, and cartridge filter 200 can follow runner 241 and control the removal. Since the air blowing plate 220 shields the left air inlet 203 and the intake air amount of the right air inlet 203 is increased, the right side of the filter cartridge 210 is subjected to the action of the air against the elastic force of the elastic member, and the filter cartridge 210 is moved to the left side. When the air deflector 220 is moved to a cleaning position adjacent to the filter cartridge 210, one end of the rack 320 just abuts the filter cartridge 210. In order to facilitate the movement of the rack 320, a limiting plate 212 is disposed on the filter element 210, the limiting plate 212 abuts against one end of the rack 320, and when the filter element 210 moves to the left, the rack 320 is pushed.
When more dust adheres to the filter element 210, the air is difficult to pass through the filter element 210 and pushes the filter element 210 to move to the left by a larger distance, at this time, the distance that the filter element 210 pushes the rack 320 increases, so that the rotating angle of the return pipe 230 increases, the overlapping area of the vent hole 231 of the return pipe 230 and the opening of the air passage 222 increases, and thus, a large amount of wind is blown out by the wind blowing hole 223 to clean the filter element 210 with more dust; when dust adhering to the cartridge 210 is small, the distance that the air pushes the cartridge 210 to move to the left is reduced, so that the angle by which the rotary assembly 300 drives the return pipe 230 to rotate is small, the overlapping area of the vent hole 231 of the return pipe 230 and the opening of the air passage 222 is small, and the air volume blown out by the air blowing hole 223 is reduced.
In a further embodiment, as shown in fig. 5, the air blowing holes 223 are obliquely arranged downward, and the position where the air blowing holes 223 are communicated with the air duct 222 is higher than the position where the air blowing holes 223 are opened at the air blowing plate 220, and the obliquely arranged air blowing holes 223 can enable air to be obliquely blown to the surface of the filter element 210, and compared with the direction perpendicular to the surface of the filter element 210, the obliquely arranged air direction can enable dust on the surface of the filter element 210 to be more effectively blown off, so that the dust removing efficiency on the surface of the filter element 210 is higher.
In a further embodiment, a driving motor 242 is disposed at the bottom of the filter cartridge 200, a rotating shaft of the driving motor 242 is connected with the rotating plate 240, the driving motor 242 drives the rotating plate 240 to rotate 180 ° and the filter element 210 on the rotating plate 240 synchronously rotates 180 °, so that the cleaning position of the filter element 210 is replaced, that is, after the cleaning of the left side of the filter element 210 is finished, the air blowing plate 220 is reset first, the rotating plate drives the filter element 210 to rotate 180 °, and the air blowing plate 220 moves towards the direction close to the filter element 210, so that the right side of the filter element 210 is cleaned, and the filter element 210 is ensured to be cleaned completely.
In order to facilitate connection and sealing, a reflux cover is arranged on the blowing plate 220, two connecting pipes 252 are arranged on the reflux cover, the two connecting pipes 252 are respectively communicated with the two reflux pipes 230, two sliding rails 253 are arranged at the upper end of the filter cartridge 200, the two sliding rails 253 are parallel to each other, the two connecting pipes 252 are respectively positioned in the two sliding rails 253, the two connecting pipes 252 protrude out of the two sliding rails 253, a first sealing plate 400 is arranged on the sliding rails 253, the first sealing plate 400 is arranged in the sliding rails 253 in a sliding sealing way, and the two connecting pipes 252 penetrate through the first sealing plate 400, so that when the blowing plate 220 slides in the filter cartridge 200, the sliding rails 253 cannot leak; similarly, a second sealing plate 410 is disposed at the connection between the top end of the filter element 210 and the top end of the filter cartridge 200, and the principle of the second sealing plate 410 is the same as that of the first sealing plate 400 at the sliding rail 253, which is not described in detail herein.
Specifically, a telescopic member 500 is disposed in the filter cartridge 200, the fixed end of the telescopic member 500 is connected to the filter cartridge 200, the telescopic end of the telescopic member 500 is fixedly connected to the air blowing plate 220, and the air blowing plate 220 is driven to move in a direction approaching or separating from the filter cartridge 210 when the telescopic member 500 stretches.
It should be noted that, the telescopic member 500 may be an electric control push rod, or may be a hydraulic cylinder or other structure capable of driving the air blowing plate 220 to move, which is not limited herein.
In a further embodiment, the shape of the air blowing plate 220 is semi-annular, and the air blowing plate 220 and half of the filter element 210 are matched, so that the distances between the air blowing plate 220 and the surface of the filter element 210 are equal everywhere, and the air blowing plate 220 can clean dust on the surface of the filter element 210 more uniformly during air blowing.
Specifically, as shown in fig. 2, a second vent pipe 204 is connected to a connection pipe 252 of the return end cap 250, and the second vent pipe 204 is in communication with the first vent pipe 202, where the communication position is located at the rear of the dryer 205, that is, at the air outlet end of the dryer 205, and a part of the air dried by the dryer 205 enters the return pipe 230 through the second vent pipe 204, so as to provide the air for the air blowing plate 220. When the filter element 210 is cleaned, the blowing plate 220 is driven by the telescopic piece 500 to a cleaning position close to the filter element 210, the filter element 210 moves leftwards to push the rack 320, so that the rack 320 drives the return pipe 230 to rotate, the overlapping area of the vent hole 231 and the opening of the air passage 222 is adjusted when the return pipe 230 rotates, part of air dried by the dryer 205 enters the return pipe 230 through the second vent pipe 204, passes through the overlapping area from the return pipe 230, and then is blown to the surface of the filter element 210 through the blowing hole 223 from the overlapping area.
When the filter element 210 is cleaned, if the air intake of the air inlet 203 is reduced, the air passing through the filter element 210 will also be reduced, so that the force of the air pushing the filter element 210 to move to the left is reduced, so that the overlapping area of the vent hole 231 on the return pipe 230 and the opening of the air passage 222 is smaller, and the return pipe 230 is prevented from distributing more air, so as to ensure the normal operation of the communication cabinet 100.
It can be appreciated that since the air blown out from the air blowing holes 223 is the dried air, the humidity in the filter cartridge 200 gradually decreases as the cleaning proceeds, the burden on the dryer 205 can be reduced, and the service life of the dryer 205 can be improved. After cleaning, the humidity in the filter cartridge 200 will be lower than the preset humidity, and when cleaning is performed next time, the humidity in the filter cartridge 200 needs to reach the preset humidity again, so when the external air humidity is high, the cleaning frequency of the filter element 210 will be increased, and if the external air humidity is low, the cleaning frequency of the filter element 210 will be reduced, so that the cleaning frequency is adaptively adjusted according to the external air humidity.
In a further embodiment, the second vent pipe 204 is provided with a reflux pump 206, the reflux pump 206 can increase the air flow speed of the second vent pipe 204 flowing back into the reflux pipe 230, when the air pressure in the filter element 210 is greater than the pressure between the filter element 210 and the air blowing plate 220, the air blowing plate 220 has poor effect of cleaning the surface of the filter element 210, and the pressure of the air blown by the air blowing hole 223 needs to be increased, at this time, the reflux pump 206 can be started to increase the air pressure blown by the air blowing hole 223, so that the air pressure blown by the air blowing hole 223 is greater than the air pressure in the filter element 210 to ensure that the air blowing plate 220 can maintain a better cleaning effect.
Specifically, the lower end of the blowing plate 220 is provided with a dust discharge port 270, the dust discharge port 270 is connected with a telescopic tube 260, the telescopic tube 260 is connected to the filter cartridge 200, and the telescopic tube 260 communicates the dust discharge port 270 with the outside of the filter cartridge 200, so that the gas is discharged from the dust discharge port, and dust is carried in the gas.
The following describes a specific working procedure of the dustproof 5G outdoor communication cabinet according to the present application in combination with the above embodiment:
Normal operating state:
The telescopic member 500 is in a shortened state to drive the air blowing plate 220 to be far away from the filter element 210, specifically as shown in fig. 2 and 8, the two air inlets 203 are both pumped with air, the air is discharged into the first breather pipe 202 from the air outlet 201 at the top end of the filter element 210 after passing through the filter element 210, the filtered air is dried by the dryer 205 on the first breather pipe 202 and then is introduced into the communication cabinet 100, the communication assembly in the communication cabinet 100 is cooled, and the air blowing plate 220 is not close to the filter element 210, and the vent hole 231 of the return pipe 230 on the air blowing plate 220 is not overlapped with the opening of the air passage 222, so that the second breather pipe 204 is in a closed state, and no air flows back into the second breather pipe 204.
Cleaning state:
As air continues to be input, the filter element 210 in the filter cartridge 200 gradually starts to be blocked, and the humidity in the filter cartridge 200 gradually increases, when the humidity in the filter cartridge 200 increases to a preset value, the telescopic member 500 is driven to extend, the air blowing plate 220 is pushed to a position close to the filter element 210, the air blowing plate 220 blocks the air inlet 203 on the left side, and the air inlet volume of the air inlet 203 on the right side is increased in order to ensure that the air entering the communication cabinet 100 is not changed. Because the intake volume of the air is increased and the right side intake 203 is blocked, the air blows the filter element 210 to move to the left side, the limiting plate 212 on the filter element 210 pushes the rack 320, the rack 320 drives the gear sleeve 310 to rotate, the gear sleeve 310 drives the return pipe 230 to rotate, and further the vent hole 231 on the return pipe 230 is overlapped with the opening of the air passage 222, so that a part of the air in the first vent pipe 202 flows back into the second vent pipe 204, enters the return pipe 230 through the second vent pipe 204, and is blown to the filter element 210 through the blowing hole 223 after passing through the overlapped area.
When the dust on the surface of the filter element 210 is more, the distance that the filter element 210 moves to the left side can be increased, so that the angle that the rack 320 drives the return pipe 230 to rotate is increased, the size of the overlapping area of the vent hole 231 of the return pipe 230 and the opening of the air passage 222 is increased, the larger the overlapping area is, the more the air flows back, the better the effect that the air blowing hole 223 cleans the filter element 210 is, if the dust on the surface of the filter element 210 is less, the distance that the filter element 210 moves to the left side is reduced, so that the angle that the rack 320 drives the return pipe 230 to rotate is reduced, the overlapping area is reduced, the returned air is reduced, the dust on the surface of the filter element 210 can still be cleaned, meanwhile, the humidity in the filter cartridge 200 is larger, the dust is reduced, and the cleaning effect of the filter element 210 is prevented from being influenced by the dust.
When the filter element 210 is cleaned, the air pressure inside the filter element 210 is greater than the air pressure blown out by the air blowing hole 223, so that when the cleaning effect of the filter element 210 is poor, the reflux pump 206 is started to increase the pressure of the air in the reflux pipe 230, thereby maintaining the better cleaning effect of the filter element 210.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
