Marine dedusting shutter

Abstract

The invention provides a marine dedusting shutter which comprises a rectangular frame and a shutter plate. The shutter plate comprises a window frame and a plurality of parallel blades arranged on the window frame, and is arranged on the first side of the rectangular frame in a covering mode. The marine dedusting shutter further comprises a filter net which is arranged in the rectangular frame, and the periphery of the filter net is in connection fit with the inner circumferential face of the rectangular frame. The filter net is continuous and zigzag, and a plurality of linear grooves are formed in the side, facing the shutter plate, of the filter net in a column mode. An arching part is formed between every two adjacent linear grooves. The blades and the linear grooves all extend from top to bottom. The multiple arching parts and the linear grooves located between the arching parts are formed in the outward side of the corrugated filter net, so that the filter net has larger surface area, and the probability of ventilation maintenance of the filter net is increased; and the arching parts have a shielding effect on the linear grooves, and when air brings sand and dust, the arching parts can effectively prevent the sand and dust from reaching the linear grooves, and the air permeability at the linear grooves is effectively maintained.

Description

technical field [0001] The invention relates to marine equipment, in particular to a dust-removing louver for a placer transport ship. Background technique [0002] The existing anti-dust shutters installed on the means of transportation mainly include a rectangular window frame, a plurality of blades arranged in parallel from top to bottom, a filter screen and a baffle plate, and the upper ends of the blades are respectively hinged to both sides of the rectangular window frame. The filter screen and the baffle are arranged on the outside of the rectangular window frame in turn from the inside to the outside, the two sides of the filter screen are respectively plugged into the two sides of the rectangular window frame, the baffle is against the outside of the filter screen, and several fasteners pass through the baffle respectively The sides are fixed to the rectangular window frame. [0003] Because the transported goods on the placer transport ship are building materials ...

Problems solved by technology

[0003] Because the transported goods on the placer transport ship are building materials with a large amount of dust, etc., during the operation, the sand and dust in the sand and gravel materials are mixed into the air with humidity, and the strong wind on the sea surface will also bring some sand particles , if the existing anti-dust shutters are used, since the filter is a flat filter, the erosion of seawater and the adhesion of sand particles will easily block the filter, and frequent cleaning is required to ensure the ventilation effect. Such frequent cleaning operations will give The operation of the placer carrier is inconvenient, so the shutters used by the placer carrier need to be improved
