Description

Technical Field

[0001] The utility model relates to the technical field of ship thick plate welding, in particular to a welding smoke and dust removal fan for ship thick plate welding. Background Art

[0002] A ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. In the process of manufacturing ships, welding of ship thick plates is an indispensable task. During the welding process, ship thick plates will produce waste slag, smoke, etc., so a welding smoke dust collector is needed to absorb and treat them to reduce their harm to the health of operators and prevent occupational diseases. When using a welding smoke dust collector, the dust hood needs to be moved to the welding position so that it can absorb the welding smoke in time. Although the dust hood can effectively absorb the welding smoke, when welding the ship thick plates at different angles and positions, the dust hood cannot fully cover the ship thick plates, resulting in the welding smoke generated by welding in some positions cannot be fully sucked away. For this reason, we propose a welding smoke dust removal fan for ship thick plate welding. Utility Model Content

[0003] The utility model provides a welding smoke and dust removal fan for welding thick plates of ships, which solves the problems raised by the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a welding smoke dust removal fan for thick plate welding of ships, comprising a box assembly, a dust hood connected to the box assembly, a lifting slide rail on one side of the box assembly, and a liftable adjustment frame movably connected in the lifting slide rail, the adjustment frame comprising a circular ring portion, a movable base movably connected to the inner side of the circular ring portion of the adjustment frame, and the dust hood is connected to the middle of the bottom end of the movable base through a pin, and a welding smoke duct passing through the movable base and connected to the inside of the box assembly is fixedly installed in the dust hood.

[0005] Optionally, a threaded rod is movably mounted on the box assembly and is located in the lifting rail, and the top end of the threaded rod extends out of the top end of the box assembly, and the threaded rod is threadedly connected to the portion of the adjustment frame extending into the lifting rail.

[0006] Optionally, a layered filter and purification assembly is fixedly installed inside the box assembly, and a fan assembly is fixedly installed on the top of the box assembly, and the fan assembly is located on the top of the innermost filter and purification assembly.

[0007] Optionally, an inverted conical discharge port is provided at the bottom of the box assembly and is connected to the bottom of multiple layers of filtering and purifying components. The inverted conical discharge port is installed with a closed screw plug, and one end of the welding smoke duct extending into the interior of the box assembly is facing the outermost filtering and purifying component.

[0008] Optionally, one end of the welding smoke duct extending into the interior of the box assembly is tilted upward toward the filter purification assembly, and the top of the threaded rod is fixedly connected to a rotary disc, while a universal wheel is installed at the bottom of the box assembly.

[0009] Optionally, a guide slider that can be movably connected to the annular part of the adjustment frame is fixedly connected to one side of the movable base, and a slot is opened on the dust cover, and the welding smoke duct passes through the slot, and the welding smoke duct movably passes through the movable base.

[0010] The utility model has the following beneficial effects:

[0011] 1. The welding fume dust removal fan for ship thick plate welding can adjust the position of the dust hood by rotating the movable base relative to the adjustment frame, and can adjust the angle of the dust hood by rotating the dust hood relative to the movable base, so that the dust hood can be directly facing the welding position of the ship thick plate to absorb dust, thereby achieving a better dust collection effect on the welding fume.

[0012] 2. The welding fume dust removal fan for ship thick plate welding rotates the rotary disc, which drives the threaded rod to rotate. Driven by the rotation of the threaded rod, the adjustment frame can be raised and lowered, and then the dust hood can better absorb dust from the welding position, thereby achieving better absorption of welding fume.
