[0002] A doorless defroster is a ventilation device installed at the air inlet of a ship's cabin to reduce the amount of moisture entering the cabin. The device has a built-in doorless closing device, which can close the air inlet from the outside of the cabin by turning a handwheel in extreme weather, thereby ensuring the safety of ship operation.
[0003] Currently, the demister closing device is usually a door-type cover, which is opened and closed by opening and closing the cover outside the cabin. This type of structure requires sufficient space outside the cabin to ensure that the cover can be opened. The larger the demister, the larger the space requirement. However, the space on ships is usually limited, making this type of device difficult to install.
[0004] The cover of a covered demister is connected to the body by a hinge. It requires a lot of space when it is installed. There must be enough space to open or close the cover from the outside like opening or closing a door. There must be no obstruction within the opening and closing trajectory of the cover.

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] like Figure 1-3 As shown, a doorless demister includes a frame 1, multiple louvers 2, a closing assembly, and a demister 3. The multiple louvers 2 are arranged sequentially from top to bottom on one side of the inner wall of the frame 1, and each louver 2 is rotatably connected to the frame 1 at both ends by a first bolt 4. The demister 3 is connected to the other side of the inner wall of the frame 1. The closing assembly is located at the lower end of the frame 1 and is connected to the multiple louvers 2.
[0027] Specifically, the closing component includes two linkage rods 5, each with a sliding groove 6. Limiting sliders 7 are provided on the two inner walls of the frame 1. The linkage rods 5 are slidably connected to the limiting sliders 7 through the sliding grooves 6. Each louver 2 has a first connecting rod 8 rotatably connected to both ends of its inner sidewall. The other ends of the two first connecting rods 8 are rotatably connected to a linkage rod 5. The lower end of the linkage rod 5 is connected to a drive component located at the lower end of the frame 1.
[0028] Specifically, the drive component drives the linkage rod 5 to slide up and down on the inner wall of the frame 1. When the linkage rod 5 slides upward, it drives the first connecting rod 8 to open the multiple louvers 2 by 45 degrees. When the linkage rod 5 slides downward, it drives the first connecting rod 8 to close the multiple louvers 2.
[0029] Specifically, the drive assembly includes a handwheel 9, a first rotating shaft 10 connected to the handwheel 9, a worm gear 11 connected to the first rotating shaft 10, a worm wheel 12 meshing with the worm gear 11, the worm wheel 12 being connected to the middle of a second rotating shaft 13, a second connecting rod 14 fixedly connected to each end of the second rotating shaft 13, the other ends of the two second connecting rods 14 being rotatably connected to a third connecting rod 15, and the other ends of the two third connecting rods 15 being rotatably connected to the lower end of a linkage rod 5.
[0030] Specifically, rotating the handwheel 9 causes the first shaft 10 to rotate the worm gear 11, which in turn rotates the meshing worm wheel 12. The worm wheel 12 then rotates the second shaft 13, causing the connected second link 14 to swing. The swinging of the second link 14 causes the third link 15 to move the connected linkage rod 5 up and down. Rotating the handwheel 9 clockwise causes the linkage rod 5 to slide upward, which in turn moves the first link 8, causing multiple louvers 2 to open 45 degrees. Rotating the handwheel 9 counterclockwise causes the linkage rod 5 to slide downward, which in turn moves the first link 8, causing multiple louvers 2 to open and close.
[0031] Specifically, the demister 3 is connected to the inner wall of the frame 1 on the side away from the louver 2, and the lower end of the demister 3 is connected to the storage tray 16, and the lower end of the storage tray 16 is provided with a vent 17.
[0032] Specifically, a baffle plate 18 is provided on the side of the storage tray 16 near the louvers 2. The baffle plate 18 ensures that water flowing down from the demister 3 does not flow into the compartment. The water flowing down from the demister 3 can be drained through the drain port 17.
[0033] Specifically, demister 3 is a mature product with internal blades in the form of hooked corrugated plates. Its working principle is as follows: When air containing mist flows through the demister at a certain speed, the mist collides with the corrugated plates due to the inertial impact of the gas and adheres to their surface. The diffusion of mist on the corrugated plate surface and the gravitational settling of the mist cause it to form larger droplets, which move forward with the airflow to the bends of the corrugated plates. Due to the centrifugal force of the turning, friction with the corrugated plates, adsorption, and the surface tension of the liquid, the droplets grow larger and larger until the accumulated droplets become so large that their own weight exceeds the combined force of the gas's upward force and the liquid's surface tension, at which point the droplets are separated from the corrugated plate surface. The multi-directional structure of the demister's corrugated plates increases the chances of mist capture. Any remaining mist is captured again at the next bend through the same process, and this repeated action greatly improves the demisting efficiency.
[0034] Specifically, it also includes four sets of connecting components, which are respectively connected to the four corners of the frame 1; the connecting components include a fixing plate 19, a seat plate 20, a flat washer 21, a spring washer 22, and a second bolt 23; the fixing plate 19 is connected to the outer wall of the frame 1, the seat plate 20 is embedded in the ship's bulkhead, and the fixing plate 19 and the seat plate 20 are connected by the second bolt 23; a flat washer 21 and a spring washer 22 are provided between the fixing plate 19 and the seat plate 20.
[0035] Specifically, a rodent-proof mesh 24 is installed on the outer wall of the defogger 3 to prevent rats and other rodents from entering the cabin.
[0036] Specifically, the upper end face of the frame 1 is connected to a lifting lug 25. This lug is used for hoisting equipment during installation.
[0037] Specifically, the inner wall of the frame 1 is connected to multiple channel steels 26, the number of which corresponds to the number of louvers 2. Each channel steel 26 is equipped with filler 27, and each louver 2 has a retaining strip 28 connected to the side near the channel steel 26, which can be engaged within the channel steel 26. When the demister 3 is closed, the louvers 2 can be engaged within the channel. The filler installed inside the channel steel ensures a tight seal when the louvers are engaged within the channel.
[0038] This doorless, closable demister has a low space requirement for its closing mechanism. It requires minimal space to operate and is easy to use; simply turning the handwheel opens and closes the demister. This eliminates the need for space-dependent demister placement and makes operation convenient.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
