Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation, in particular to a ventilation duct. Background Art

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are a kind of municipal infrastructure designed to allow air circulation and reduce the concentration of harmful gases. They are widely used in factories, workshops and other scenarios.

[0003] Nowadays, after installing ventilation ducts in factories, workshops and other scenes, filters are usually installed inside the ventilation ducts to filter out dust, fine particles and other impurities in the air, ensure the quality of air entering the room, meet the hygiene standards in the building, and provide a clean and comfortable environment indoors.

[0004] However, although the filter can filter the air passing through the ventilation duct, a large amount of dust, impurities, etc. will adhere to the filter after long-term use, resulting in a poor filtering effect of the filter; this requires cleaning the filter, and for this purpose, the ventilation duct needs to be removed or manual cleaning needs to be performed in the ventilation duct, which is very inconvenient.

[0005] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the above-mentioned defects, the purpose of the utility model is to provide a ventilation duct, which is convenient for manual cleaning of the filter inside the duct and is simple to operate.

[0008] Ventilation duct body;

[0009] A filter screen 1 installed inside the ventilation duct body, wherein the filter screen 1 covers the upper half of the ventilation duct body;

[0010] A second filter screen is installed inside the ventilation duct body, a cleaning brush is provided on the side of the second filter screen close to the first filter screen, and the second filter screen covers the lower half of the ventilation duct body; and a connecting rod is connected to the side of the second filter screen away from the first filter screen, and an end of the connecting rod away from the second filter screen penetrates the ventilation duct body and extends to the bottom of the ventilation duct body;

[0011] The ventilation duct body is provided with a dust outlet located directly below the first filter and the second filter.

[0012] According to a ventilation duct described in the utility model, two opposite sides of the filter screen one close to the filter screen two are vertically provided with slide grooves, and the filter screen two close to the filter screen one is provided with a sliding shaft that is adapted to the number and position of the slide grooves.

[0013] According to a ventilation duct described in the utility model, when the sliding shaft slides to the bottom of the slide slot, the ground clearance of the bottom end of the connecting rod is 140 cm, and when the sliding shaft slides to the top of the slide slot, the ground clearance of the lowest end of the connecting rod is 160 cm.

[0014] According to the ventilation duct described in the utility model, a collection bag connected to a dust outlet is provided on the outside of the ventilation duct body.

[0015] According to the ventilation duct described in the utility model, it also includes a hanging assembly, which includes a plurality of hanging groups, and each of the plurality of hanging groups includes a channel steel cross arm and hanging rods located at two opposite sides of the ventilation duct body.

[0016] According to the ventilation duct described in the utility model, a plurality of the hanging components are preset at the upper wall corners inside the building.

[0017] The utility model provides a ventilation duct, which has the following beneficial effects:

[0018] 1. By manually holding the connecting rod to push and pull up and down, the filter 2 will collide with the inner top and inner bottom of the ventilation duct body for multiple times, and the dust and impurities adhered to the filter 2 will fall off significantly after the impact; at the same time, the up and down movement of the filter 2 will also drive the cleaning brush to clean the filter 1 up and down, so that the dust and impurities on the filter 1 will fall off, thereby achieving the effect of cleaning the filter 1 and the filter 2 at the same time. The operation is simple and easy to use, and there is no need to manually reach into the ventilation duct body for operation.

[0019] 2. By arranging a collection bag connected to the dust outlet on the outside of the ventilation duct body, it is convenient to collect dust, impurities, etc. that fall on the filter screen 1 and the filter screen 2, and prevent dust, impurities, etc. from falling directly on the ground.
