Problems solved by technology

Since the inner upper end of the ventilation column needs to be specially coated, and the upper and lower ends need to be separated by a partition, the operation is difficult, and because of the large size, the manufacturing is troublesome, the volume is huge after production, and the hoisting is difficult. In addition, special coating is required in the ventilation tube. Grinding, poor working environment, increased labor intensity, increased production costs

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] Such as figure 1 As shown, a ship ventilation device includes a special coating pipe 1, the inner wall of the special coating pipe 1 has undergone a special coating process, and there is no need to manually enter the inside of the pipe for special coating, which reduces labor intensity and reduces the harsh working environment. The inner diameter of the tube 1 is 300-450mm, such as 350mm, 375mm, 400mm, 410mm, 430mm, which can meet the air flow requirements of general ships. The top of the specially coated tube 1 is provided with a spark extinguisher. The spark extinguisher has little difference in diameter, and it is not necessary to arrange a reducer on the specially coated pipe 1. The structure is simple, the labor intensity is reduced, and the weight is reduced because the diameter is smal...

Abstract

The invention discloses a ventilation device for a ship, and relates to the technical field of shipping equipment. The ventilation device for the ship comprises a special coating pipe, wherein the inner wall of the special coating pipe is subjected to a special coating technology; the inner diameter of the special coating pipe is 300-450 mm; the top of the special coating pipe is provided with a spark arrester. The ventilation device for the ship disclosed by the invention has the advantages that the technological steps for fabrication are reduced due to being free from the special coating technology, the severe working environment is reduced, the weight is reduced due to the reduction of a diameter, the difficulty in installation is lowered, the type is simple, the fabrication is easy, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a ship ventilation device. Background technique [0002] The existing public ventilating column is formed by bending and splicing a piece of steel plate. Since the interior needs special coating, grinding and other processes, operators need to enter the interior of the column. Therefore, the inner diameter of the public ventilating column needs to be set to 600mm or more. It is larger than the diameter required for ventilation of general ships. If only the air flow is considered, the diameter of the ventilation column can meet the needs between 300-450mm. The existing ventilation column wastes too much material and increases the weight. A spark extinguisher needs to be installed on the top of the existing column. The size of the spark extinguisher is fixed within a certain range of air flow. Therefore, the diameter of the spark extinguisher on a general ship is about 400mm...
