Description

Technical Field

[0001] The invention relates to the technical field of air dampers, and in particular to an adjustable air damper with pressure difference adjustment and filtering functions. Background Art

[0002] At sea, the ventilation system of some ships is crucial for transportation. The regulation of internal and external air pressure and circulation of the ventilation system is generally achieved by adjusting the damper. However, due to the presence of marine salt spray, the ventilation system of offshore ships or platforms is prone to corrosion and affect equipment and systems. In the process of regulating internal and external air pressure and air circulation, it is necessary to detect and control the internal and external air pressure of the damper. The differential pressure controller, as a more precise differential pressure control device commonly used in ventilation systems, is susceptible to corrosion and influence.

[0003] In particular, the chloride ions in the salt mist penetrate the oxide layer and protective layer on the metal surface, and react electrochemically with the internal metal, resulting in corrosion of equipment such as the differential pressure controller. The chloride ions in the salt mist reduce the surface resistance and volume resistance of the insulator, affecting the normal operation of electronic components and electrical circuits. Salt mist pollutes the air and water quality, which may pose a risk to human health. In order to prevent salt mist from affecting the air circulation system on offshore ships, platforms and other equipment and buildings, it is usually necessary to install a salt mist filter in front of the regulating damper of the relevant systems and equipment. However, due to the position and installation requirements of the damper of the ventilation system of ships and other ventilation systems, the salt mist filter is set far away from the damper, or the volume is too large to be set separately. Therefore, the present invention provides a damper with differential pressure control and adjustment of the salt mist filtration system, and can automatically replace the salt mist filter plate to achieve the integration and miniaturization of the damper, differential pressure controller and salt mist filtration system.

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1 and 2 As shown, the following preferred technical solutions are provided:

[0029] A regulating damper with pressure difference regulating and filtering functions, comprising: a regulating damper 1 for regulating internal and external air pressures, a filtering device 2 for filtering external air, and a pressure difference controller 3 for monitoring and controlling the internal and external pressure difference, the filtering device 2 is arranged on the air inlet end side of the regulating damper 1 through an air inlet pipe 5, the pressure difference controller 3 is arranged on the regulating damper 1 and the two ends of the pressure difference controller 3 are respectively connected to the air inlet end and the air outlet end of the regulating damper 1, the pressure difference controller 3 is connected to the regulating damper 1 through an actuator 4, and the opening and closing of the regulating damper 1 is controlled by the actuator 4, the filtering device 2 is connected to one side of the air inlet pipe 5, one end of the air inlet pipe 5 is connected to the regulating damper 1 and the other end is connected to a pipe opening and closing device 6, the filtering device 2 comprises a filter plate replacement assembly 21, a filter plate moving assembly 22 and a filter box 23, the filter plate replacement assembly 21 and the filter plate moving assembly 22 are both installed in the filter box 23, the filter box 23 is installed on one side of the air inlet pipe 5 and is connected thereto, and the filter plate replacement assembly 21 and the filter plate moving assembly 22 are both transmission-connected to the pipe opening and closing device 6.

[0030] Specifically, in order to solve the technical problems of regulating and controlling the pressure difference between the inside and outside of the air damper of the ship ventilation system and filtering and replacing the filter plate during the regulation process, the present invention installs a pressure difference controller 3 on the regulating air damper 1 to monitor the pressure difference between the inside and outside of the regulating air damper 1, and uses the filter plate moving component 22 to move the filter plate into the air inlet pipe 5 and dock with the pipe mouth during the regulation process, and filters the air entering the air inlet pipe 5. When the sensor detects that the air salt mist in the air inlet pipe 5 exceeds the standard, the filter plate replacement component 21 automatically replaces the filter plate. The present invention realizes the integration and automation of the regulating air damper 1, the pressure difference controller 3 and the filtering device required for the ship ventilation system, improves the corrosion resistance of the regulating air damper 1, and effectively improves the use environment of the ship ventilation system or air conditioning system.

[0031] like Figure 3 As shown, the following preferred technical solutions are provided:

[0032] The pipe opening and closing device 6 includes an actuator motor 61 and a shutter opening and closing mechanism 62. The actuator motor 61 is connected to the shutter opening and closing mechanism 62 through a gear set 63. The shutter opening and closing mechanism 62 is installed at the air inlet pipe 5 through a mounting shell 64. The actuator motor 61 is installed on the mounting shell 64. The filter plate moving assembly 22 is connected to the driving gear 631 of the gear set 63.

[0033] Specifically, in order to solve the technical problem of opening and closing the air inlet pipe 5, the present invention uses a shutter opening and closing mechanism 62 as the valve of the pipe mouth, and the shutter opening and closing mechanism 62 is controlled by the actuator motor 61 and the gear set 63. When the filter plate needs to be replaced, the shutter opening and closing mechanism 62 closes the pipe mouth to prevent unfiltered external air from entering during the replacement process.

[0034] like Figures 1 to 8 As shown, the following preferred technical solutions are provided:

[0035] The filter plate moving assembly 22 includes a moving frame 221 and a docking rail plate 222. One end of the moving frame 221 is installed in the filter box 23 through a guide rail 223, and the other end is transmission-connected to the driving gear 631 of the gear set 63 through a lower rack 224. The lower rack 224 is slidably installed in the filter box 23 through a lower rack rail 225. The transmission gear 632 of the gear set 63 on the shutter-type opening and closing mechanism 62 is transmission-connected to the lower rack 224, and the transmission connection docking rail plate 222 is arranged on the upper and lower sides of the filter box 23.

[0036] A filter frame 226 for placing a filter plate is installed on the mobile frame 221. The filter frame 226 is connected to the mobile frame 221 through a main connecting rod 227 and a secondary connecting rod 228. Both ends of the main connecting rod 227 and the secondary connecting rod 228 are respectively hinged to the upper end of the mobile frame 221 and the filter frame 226. One end of the main connecting rod 227 connected to the mobile frame 221 is slidably connected to the docking rail plate 222 through a connecting column 229.

[0037] The docking rail plate 222 is provided with horizontal and obliquely interconnected rail grooves 220 , and the connecting column 229 at the connection between the main connecting rod 227 and the moving frame 221 is slidably connected to the horizontal and oblique rail grooves 220 on the docking rail plate 222 .

[0038] Specifically, in order to solve the technical problem of connecting the mobile frame 221 to the pipe mouth during the replacement of the filter plate, the present invention drives the driving gear 631 of the gear set 63 to rotate by the execution motor 61, and the driving gear 631 drives the lower rack 224 to move. When the pipe mouth is open, the lower rack 224 is meshed with the transmission gear 632 on the shutter opening and closing mechanism 62. The movement of the lower rack 224 drives the transmission gear 632 to rotate so that the shutter opening and closing mechanism 62 gradually closes the pipe mouth. This method can also be used to adjust the size of the pipe mouth. When the pipe mouth is closed, the lower rack 224 is no longer meshed with the transmission gear 632. While the lower rack 224 moves, it drives the mobile frame 221 to slide in the filter box 23, and drives the filter frame 226 connected thereto to move on the docking rail plate 222, so that the filter frame 226 is retracted into the filter box 23, and the horizontal and oblique rail grooves 220 on the docking rail plate 222 are used to change the docking state of the filter frame 226 and the pipe mouth.

[0039] like Figures 1 to 8 As shown, the following preferred technical solutions are provided:

[0040] The filter plate replacement assembly 21 includes a replacement rack 211 and a filter plate box 212 for storing the filter plates. The replacement rack 211 is slidably connected to the filter box 23 via a slide rail. The filter plate box 212 is slidably clamped on the replacement rack 211. The replacement rack 211 is transmission-connected to the lower rack 224 via an upper rack 213. The upper rack 213 is slidably installed in the filter box 23 via an upper rack rail 214 and is located above the lower rack 224. The upper rack 213 and the lower rack 224 are meshed and transmitted via a connecting gear 215. The connecting gear 215 is rotationally connected to the side wall of the filter box 23.

[0041] A telescopic assembly 216 is disposed on the replacement rack 211 , and a movable end of the telescopic assembly 216 faces the filter plate box 212 on the replacement rack 211 .

[0042] A recovery box 217 is provided on one side of the filter box 23 close to the filter frame 226 . The recovery box 217 is slidably connected to the filter box 23 and faces the filter frame 226 .

[0043] Specifically, in order to solve the technical problem of automatic replacement of filter plates, the present invention realizes the movement of the replacement rack 211 through the transmission connection between the lower rack 224 and the upper rack 213. When the lower rack 224 moves to the connecting gear 215, the lower rack 224, the connecting gear 215 and the upper rack 213 are meshed for transmission. The upper rack 213 moves in opposite directions to the lower rack 224. When the movable rack 221 and the filter rack 226 are reset to the filter box 23, the upper rack 213 drives the replacement rack 211 and the filter plate box 212 to move to the position opposite to the filter rack 226. The telescopic component 216 is started to push the spare filter plate stored in the filter plate box 212 onto the filter rack 226. The spare filter plate pushes the original filter plate on the filter rack 226 into the recovery box 217 to complete the replacement.

[0044] After the replacement is completed, the telescopic assembly 216 is reset, and the execution motor 61 works in the reverse direction, driving the lower rack 224 to move toward the pipe mouth. At the same time, the upper rack 213 drives the replacement frame 211 and the filter plate box 212 to reset. After the replacement frame 211 is reset, the connecting gear 215 is disengaged from the lower rack 224, and the lower rack 224 continues to move and continues to drive the moving frame 221 and the filter frame 226 to move toward the air inlet pipe 5. When the filter frame 226 and the main connecting rod 227 move to the oblique rail groove 220 of the docking rail plate 222, the lower rack 224 begins to engage and transmit with the transmission gear 632 on the shutter type opening and closing mechanism 62, so that the pipe mouth is opened synchronously.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
