Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and more specifically to an air purification device for air conditioning return air vents adapted to the vibration environment of ships. Background Technology

[0002] The air purification device for ship air conditioning return air vents is an air purification device specifically developed for ship air conditioning systems. Ships face unique environments during operation, including vibration, humidity, and confined spaces, making air purification extremely challenging. This device was developed to address these challenges. Through structural optimization and intelligent design, its core function is to ensure efficient air purification even under complex shipboard conditions, while also withstanding harsh conditions such as hull vibration and salt spray corrosion.

[0003] Traditional air purification devices for ship air conditioning return air vents typically contain filters. However, when a large amount of dust accumulates on the filter surface, it is necessary to regularly purchase new filters for replacement or to shut down the system for cleaning. This practice undoubtedly increases the material costs of ship operation. Furthermore, filter replacement requires manual operation, which generates labor costs. This cost increase is particularly pronounced for large ships or when there are a large number of filters. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an air purification device for air conditioning return air vents that is adapted to the vibration environment of ships, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an air purification device for air conditioning return air inlets adapted to ship vibration environments, comprising a return air purification device body, a filter chamber inside the return air purification device body, an air inlet at the top center of the return air purification device body, a dust discharge hole on the side of the return air purification device body, a sealing plate rotatably connected inside the filter chamber, an elastic block fixedly connected inside the return air purification device body, a fixed frame fixedly connected to the inner wall of the elastic block, a filter screen fixedly installed on the inner wall of the fixed frame, a fixed bracket fixedly connected to the bottom of the fixed frame, a fixed rod fixedly connected inside the filter chamber, a fixed sleeve fixedly connected to the end face of the fixed rod, a dual-shaft motor fixedly installed at the center of the fixed sleeve, a fan impeller fixedly installed at one output end of the dual-shaft motor, and a conversion component installed at the connection between the other output end of the dual-shaft motor and the fixed bracket.

[0006] Furthermore, the conversion assembly includes a sleeve fixedly connected to the end face of the fixed frame, with protrusions fixedly connected at equal intervals on the inner wall of the sleeve, and a rotating column fixedly connected to the output end of the dual-axis motor away from the impeller. A groove is formed on the surface of the rotating column, and a rotating rod is rotatably connected inside the groove. A stop block is fixedly connected to the outer surface of the rotating rod.

[0007] Furthermore, silicone plates are fixedly connected to both sides of the sealing plate, and a drive motor is fixedly installed inside the main body of the return air purification device. A rotating shaft is fixedly connected to the output end of the drive motor, and the outer surface of the rotating shaft is fixedly connected to the inside of the sealing plate.

[0008] Furthermore, the rotating column is rotatably connected inside the sleeve, and a coil spring is installed at the connection between the rotating rod and the groove. Under normal conditions, the elasticity of the coil spring causes the end face of the abutment to extend to the outside of the groove.

[0009] Furthermore, the surface of the silicone plate is sealed and attached to the input end of the ash discharge hole, and the elastic block is a square annular silicone block.

[0010] Furthermore, the protrusion is hemispherical, and the surface of the abutment is arc-shaped.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by setting up a conversion component and a sealing plate, allows for the sealing of the air inlet by rotating the sealing plate when it is necessary to clean dust and debris from the filter screen. Combined with the reverse rotation of the impeller, this vibrates the filter screen. Simultaneously, the reverse rotation of the impeller causes the airflow to flow in the opposite direction, dislodging the dust from the filter screen and expelling it through the dust discharge hole. The cleaning of dust and debris primarily relies on the coordinated operation of the internal structure of the device, rather than frequent replacement of parts, significantly reducing material costs for ship operations. The entire cleaning process is relatively automated, reducing manual intervention and labor costs. This labor-saving effect is particularly pronounced for large ships or ships with a large number of filters.

[0013] 2. This utility model, by setting a groove and abutment, when the dual-shaft motor drives the impeller to rotate in the opposite direction, it will also drive the rotating column to rotate in the opposite direction. Through the connection of the abutment and the protrusion, the filter screen is vibrated. When the impeller rotates in the forward direction, after the abutment contacts the protrusion, the abutment will be housed inside the groove, avoiding the vibration of the filter screen and preventing dust from penetrating deep into the interior of the filter screen. This enhances flexibility. Through the setting of the elastic block, when the main body of the return air purification device is in normal use and encounters the turbulence and vibration of the ship's hull, the vibration of the filter screen can be reduced by the buffering of the elastic block, which can prevent the dust on the surface of the filter screen from penetrating deep into its interior and becoming difficult to clean.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] An air purification device for air conditioning return air vents adapted to ship vibration environments includes a return air purification device body 1, a filter chamber 2 inside the return air purification device body 1, an air inlet 3 at the top center of the return air purification device body 1, a dust discharge hole 4 on the side of the return air purification device body 1, a sealing plate 5 rotatably connected inside the filter chamber 2, an elastic block 6 fixedly connected inside the return air purification device body 1, a fixing frame 7 fixedly connected to the inner wall of the elastic block 6, a filter screen 8 fixedly installed on the inner wall of the fixing frame 7, a fixing bracket 9 fixedly connected to the bottom of the fixing frame 7, a fixing rod 11 fixedly connected inside the filter chamber 2, a fixing sleeve 12 fixedly connected to the end face of the fixing rod 11, a dual-shaft motor 13 fixedly installed at the center of the inside of the fixing sleeve 12, a fan impeller 14 fixedly installed at one output end of the dual-shaft motor 13, and a conversion component 10 installed at the connection between the other output end of the dual-shaft motor 13 and the fixing bracket 9.

[0022] The conversion assembly 10 includes a sleeve 105 fixedly connected to the end face of the fixed frame 9. The inner wall of the sleeve 105 is fixedly connected with protrusions 106 at equal intervals. The output end of the dual-axis motor 13 away from the impeller 14 is fixedly connected to a rotating column 101. The surface of the rotating column 101 is provided with a groove 102. The inside of the groove 102 is rotatably connected to a rotating rod 103. The outer surface of the rotating rod 103 is fixedly connected to a stop block 104.

[0023] In this embodiment, by setting up the conversion component 10 and the sealing plate 5, when it is necessary to clean the dust and debris on the filter screen 8, the air inlet 3 is sealed by rotating the sealing plate 5. With the reverse rotation of the impeller 14, the filter screen 8 can be vibrated. At the same time, when the impeller 14 rotates in the reverse direction, the airflow flows in the opposite direction and discharges the dust shaken off the filter screen 8 through the dust discharge hole 4. When cleaning dust and debris, the main function is to utilize the coordinated operation of the internal structure of the device, rather than frequently replacing parts, which greatly reduces the material cost of ship operation. The entire cleaning process is relatively automated, reducing the degree of manual intervention and reducing labor costs. Especially for large ships or when there are many filter screens 8, the labor saving effect is more prominent.

[0024] Specifically, silicone plates 51 are fixedly connected to both sides of the sealing plate 5, and a drive motor 53 is fixedly installed inside the main body 1 of the return air purification device. A rotating shaft 52 is fixedly connected to the output end of the drive motor 53, and the outer surface of the rotating shaft 52 is fixedly connected to the inside of the sealing plate 5.

[0025] In this embodiment, by setting a silicone plate 51, when the sealing plate 5 rotates to a certain angle, it can seal the air inlet 3 or the ash discharge hole 4.

[0026] Specifically, the rotating column 101 is rotatably connected inside the sleeve 105, and a coil spring is installed at the connection between the rotating rod 103 and the groove 102. Under normal conditions, the elasticity of the coil spring causes the end face of the abutment 104 to extend to the outside of the groove 102.

[0027] In this embodiment, when the dual-axis motor 13 drives the impeller 14 to rotate in the opposite direction, it also drives the rotating column 101 to rotate in the opposite direction. Through the connection between the abutment block 104 and the protrusion 106, the filter screen 8 is vibrated. When the impeller 14 rotates in the forward direction, after the abutment block 104 contacts the protrusion 106, the abutment block 104 will be housed inside the groove 102, which prevents the filter screen 8 from vibrating and causing dust to seep into the deep interior of the filter screen 8, thus enhancing its flexibility.

[0028] Specifically, the surface of the silicone plate 51 is sealed and attached to the input end of the ash discharge hole 4, and the elastic block 6 is a square ring silicone block.

[0029] In this embodiment, by setting the elastic block 6, the intensity of the vibration of the filter screen 8 can be increased, and at the same time, it has a certain noise reduction effect on the main body 1 of the return air purification device. Furthermore, through the buffering of the elastic block 6, the vibration of the filter screen 8 can be reduced during normal return air use, which can avoid the disadvantage of the dust on the surface of the filter screen 8 penetrating deep into its interior and being difficult to clean due to the vibration caused by the hull rocking.

[0030] Specifically, the protrusion 106 is hemispherical, and the surface of the abutment 104 is arc-shaped.

[0031] In this embodiment, since the impact surfaces of both the protrusion 106 and the abutment 104 are arc-shaped, the contact between the two is smoother, thereby effectively reducing the instantaneous impact force and extending the service life of the component.

[0032] The working principle and usage process of this utility model are as follows: In use, the bottom end of the main body 1 of the return air purification device is installed at the air inlet of the air conditioner. The return air duct of the air conditioner is connected and sealed to the air inlet 3. Then, the ash discharge hole 4 faces outdoors or is connected to the outdoors through an external pipe. During operation, the dual-shaft motor 13 drives the impeller 14 to rotate, and the return airflow enters the filter chamber 2 through the air inlet 3. After being filtered by the filter screen 8, it enters the air inlet duct of the air conditioner. When the filter screen 8 needs to be cleaned, the drive motor 53 is started to drive the rotating shaft 52 to rotate. The rotating shaft 52 drives the silicone plate 51 to rotate and seal the air inlet 3. At this time, the ash discharge hole 4 is in communication with the inside of the filter chamber 2. The dual-shaft motor 13 drives the impeller 14 to rotate in the opposite direction. The dual-shaft motor 13 drives the abutment 104 to rotate through the fixed rod 11, and the surface of the abutment 104 strikes the surface of the protrusion 106, thereby vibrating the fixed frame 7 and the filter screen 8. With the reverse rotation of the impeller 14, the airflow flows in the opposite direction and discharges the dust shaken off the filter screen 8 through the dust discharge hole 4. When cleaning dust and debris, the main function is to utilize the coordinated operation of the internal structure of the device, rather than frequently replacing parts, which greatly reduces the material cost of ship operation. The entire cleaning process is relatively automated, reducing the degree of manual intervention and reducing labor costs. The labor saving effect is even more prominent, especially for large ships or when there are many filter screens 8.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
