Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage filter in which rainwater collected on a roof of a marine chimney is interposed in a pipe for draining it onto an exposed deck.

[0002]

[Prior art]

 Conventionally, this type of device has not been particularly devised, and a drain pipe is piped from the lower part of the chimney to the outside of the chimney through a drain hole provided in the top plate of a marine chimney, through the inside of the chimney. The rainwater collected at the drain enters the drain pipe inside the chimney through the drain hole, goes out from the lower part of the chimney to the outside of the chimney, and flows down on the exposed deck.

[0003]

[Problems to be solved by the device]

 As described in the prior art, the rainwater collected on the roof of a marine chimney contains soot, and when the soot-containing rainwater flows directly through the drain pipe onto the exposed deck, There was a problem that it became dirty with soot and it took a long time to clean the exposed deck.

The present invention has been made in view of the above problems of the conventional technology, and its purpose is to separate soot from rainwater and use it as drainage. It intends to provide a drainage filter for a ship chimney that prevents dirt on the exposed deck.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a drainage filter to be installed in a lower pipe of a drainage pipe in a marine chimney, a cylindrical outer plate which is vertically arranged and has an open upper surface, and a cylindrical outer plate which is directly above the bottom surface. A primary partition plate that vertically divides the inside of the outer plate cylinder into a drainage filtration chamber and a region other than the drainage filtration chamber, and a filtration wire mesh that horizontally partitions the drainage filtration chamber and is detachably attached. , A secondary partition plate vertically separating the drainage filtration chamber from directly above the bottom into a filtered water temporary storage chamber and a drainage chamber for the filtered water. A drainage pipe is connected from the plate, and the drainage pipe is pierced from the bottom surface of the outer wall of the drainage chamber for filtering water of the drainage filter to the outside of the chimney at the bottom of the marine chimney.

[0006]

[Action]

 The primary partition plate is formed by partitioning the drainage filtration chamber inside the outer cylinder, and distinguishes between the space for filtering rainwater as drainage and the space for draining filtered rainwater.

The secondary partition plate distinguishes a space other than the drainage filter chamber in the outer plate cylinder into a space for temporarily storing filtered rainwater and a space for directly connecting to a drain pipe connected to the outside of the chimney.

[0008]

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, in a drainage filter 4 to be interposed in a lower pipe of a drainage pipe in a marine chimney, the drainage filter 4 is arranged vertically and has an open upper surface. A cylindrical outer plate 5 is provided.

A circulation hole 10 is provided directly above the bottom surface, and the primary partition plate 6 is vertically fixed in the cylinder of the outer plate 5, and is partitioned into the drainage filtration chamber A and the drainage filtration chamber A other than the drainage filtration chamber A. The inside is divided horizontally and the filtration wire mesh 8 is detachably attached.

Aside from the drainage filtration chamber A, a filtered water temporary storage chamber B and a filtered water drainage chamber C are vertically partitioned from immediately above the bottom surface by a secondary partition plate 7.

A drain pipe 3 connected from a top plate 13 is connected to a side surface of the outer plate 5 of the drainage filtration chamber A, and penetrates from a bottom face of the outer plate 5 of the drainage chamber C for filtered water to a drain hole 12 below the chimney outer cylinder 2. Then, the drain pipe 11 is connected.

In this embodiment, the rainwater 14 collected on the top plate 13 of the chimney outer cylinder 2 flows into the drain pipe 3 along the inclined top plate 13 and enters the drain filter chamber A in the drain filter 4. . The soot 15 is removed from the rainwater 14 mixed with the soot 15 when passing through the filtration wire net 8.

The rainwater 14 accumulates in the drainage filtration chamber A, and the filtered water temporary storage chamber B also collects at the same water surface height as the drainage filtration chamber A, and the rainwater 14 filtered from the upper end of the secondary partition plate 7 is filled. When it overflows, the overflowed rainwater 14 flows down into the drainage chamber C for filtered water, flows through the drainage pipe 11 connected to the bottom of the drainage chamber C for filtered water, and goes out of the chimney through the drainage hole 12 to expose the exposed deck. Runs down one.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Before the rainwater that collects on the roof of a marine chimney flows down onto the exposed deck, the soot mixed with the rainwater is separated. Cleaning is easy and can be completed in a short time.
