Description

Technical Field

[0001] The utility model relates to the technical field of ship ventilation, in particular to a dust-proof filtering device for a ship ventilation duct. Background Technique

[0002] Ship ventilation refers to the process of delivering fresh air from the outside to the ship's cabin by mechanical or natural means and exhausting the polluted air in the cabin to keep the air in the cabin clean, at a suitable temperature and humidity, so as to meet the living and working needs of crew members and passengers, and at the same time ensure the normal operation of ship equipment.

[0003] At present, there are still certain deficiencies in the actual use of the existing dust-proof equipment for ships through pipelines: the existing filtering device lacks a structure for quickly replacing the filter screen, resulting in the filter screen being blocked by dust particles after long-term use, and the staff cannot quickly remove and replace it during disassembly and assembly, affecting subsequent use. Based on the existing technical deficiencies, the utility model designs a dust-proof filtering device for a ship ventilation duct. Content of the Utility Model

Inner wall support plates are installed on both sides inside the main body of the ventilation duct. Two sliding grooves are opened on both sides of the inner wall support plates. A quick-release structure is arranged inside the two sliding grooves; the quick-release structure includes a filter box, the filter box is slidably connected to the sliding groove, air guide pipes are arranged on both sides inside the filter box, a clamping cover is arranged at the bottom of the filter box, lifting handles are installed on both sides of the bottom of the clamping cover, a clamping groove plate is fixedly installed at the top of the clamping cover, a notch is opened on one side of the clamping groove plate, a filter screen is clamped inside the clamping groove plate, four rotating shafts are installed at the bottom of the filter box, and support blocking rods are rotatably installed at one ends of the four rotating shafts.

[0006] As a preferred technical solution of the utility model, two side blocks are installed on both sides of the outer surface of the main body of the ventilation duct, and the two side blocks are arranged on both sides of the filter box.

[0007] As a preferred technical solution of the utility model, two insertion rods pass through the inside of the filter box, and the two insertion rods are movably connected to the side blocks.

[0008] As a preferred technical solution of the utility model, threaded grooves are opened at one ends of the two insertion rods, and fixing nuts are threadedly installed at the threaded groove ends of the two insertion rods.

[0011] As a preferred technical solution of the utility model, a motor for providing power is arranged inside the fan.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The dust-proof filter device for ship ventilation duct has a quick-disassembly structure. Under normal conditions, the wind is driven by the fan to pass through the filter and enter the cabin. When the filter needs to be replaced, the staff moves the four support bars to the outside of the card cover, and then pulls the handle to make the card cover drive the card slot plate to detach from the filter box, and the filter can be pulled out from the side opening of the card slot plate for replacement, or it can be cleaned and then inserted into the card slot plate. The structure is welded with aluminum plates as a whole, and the card cover and other structures on it can be fully supported by the four support bars, thereby avoiding the cumbersome disassembly of the traditional filter device by screw fixing, and achieving the purpose of quick disassembly and replacement of the filter;

[0014] 2. This dust-proof filtering device for ship ventilation ducts has a quick-release structure and side blocks. The filter box can be fixed by inserting two plug rods from one side block, passing through the filter box and then exiting from the other side block, and then tightening and fixing them with fixing nuts. When the device needs to be disassembled as a whole for maintenance, the two plug rods can be removed, and then the filter box can slide out of the sliding groove, so that quick disassembly is achieved for easy maintenance.
