Description

Technical Field

[0001] This application relates to the field of marine engineering, and more particularly to a pipeline filter device for marine equipment. Background Technology

[0002] During shipbuilding, due to the influence of the working environment, a lot of debris such as mud, sand, iron filings, rust, and welding slag tends to adhere to the inner surface of the pipelines during manufacturing, transportation, and storage. Generally, pipeline filters are installed at the inlet of the ship's system pipelines to filter out debris from the media. However, these filters are often used to filter out debris from external media and are not effective at filtering impurities inside the pipes.

[0003] Although ship systems typically have inline filters at the inlet to filter out foreign media, they are difficult to filter impurities inside the pipes. Therefore, during actual ship construction and commissioning, impurities often damage expensive equipment, causing serious economic losses. To address this, there are generally two methods: one is to add conventional inline filters at the equipment inlet. However, due to the large number of equipment on board and the high price of commercially available filters, using them only to filter those adhering to the pipes would significantly increase costs and is not suitable for large-scale use. The second method is to add filter screens to the pipes. While this method can prevent impurities from entering the equipment, it is not easy to remove impurities, and they tend to settle at the filter screen, causing pipe blockage.

[0004] Regarding the aforementioned technologies, the inventors believe that while conventional pipeline filters can prevent impurities from entering the equipment during ship construction and commissioning, they are not easy to remove and tend to settle on the filter screen, causing pipeline blockage. Conventional pipeline filters are also expensive. Utility Model Content

[0005] To address the issue of impurities and debris entering equipment from pipelines during ship construction and commissioning, this application provides a pipeline filter for ship equipment inlets.

[0023] The following will be described in combination with the drawings Figure 1 The present application will be further described in detail.

[0024] The present application discloses a pipeline filter for a ship equipment inlet. Referring to Figure 1 A pipeline filter for a ship equipment inlet includes a filter housing 1, and the water inlet and the water outlet of the filter housing 1 are fixedly connected with connecting pieces 2. The inside of the filter housing 1 is provided with a filter screen 5, which is used to block and filter impurities in the flow-through medium located inside the filter housing 1. A flow-through opening 31 is formed at the position of the bottom wall of the filter housing 1 relative to the filter screen 5, and an object connecting pipe 4 is arranged at the position of the filter housing 1 relative to the flow-through opening 31, and the bottom end of the object connecting pipe 4 is provided with a closing assembly 32 for closing the object connecting pipe.

[0025] The connecting pieces 2 are flange parts, one of which is installed at the water inlet of the filter housing 1, and the other flange part is installed at the water outlet of the filter housing 1. The two flange parts fix the filter housing 1 on the pipeline of the ship. The filter housing 1 is used for guiding the medium in the pipeline, so that the medium located inside the filter housing 1 flows from the side of the water inlet to the side of the water outlet, and then the side of the filter screen 5 close to the water inlet is the water-facing surface of the filter screen 5.

[0026] The flow-through opening 31 is located between the water inlet and the water outlet of the filter housing 1, and the impurities in the medium located inside the filter housing 1 are discharged to the outside of the filter housing 1.

[0027] The inside of the material receiving pipe 4 is communicated with the flow passage 31 on the filter housing 1, and the material receiving pipe 4 is perpendicular to the filter housing 1 to facilitate the discharge of the impurities. The inside space of the material receiving pipe 4 is communicated with the inside space of the filter housing 1 through the flow passage 31. The material receiving pipe 4 is used to accumulate and store the impurities filtered by the filter screen 5.

[0028] The closing assembly 32 comprises a closing plate 321 connected to the bottom end of the material receiving pipe 4. The closing plate 321 is used to seal the opening at the lower end of the material receiving pipe 4, and the closing plate 321 completely closes the opening at the bottom end of the material receiving pipe 4. The closing plate 321 can be removed from the material receiving pipe 4, and after the closing plate 321 is removed, the impurities in the inside of the material receiving pipe 4 can be taken out from the material receiving pipe 4, or the filter screen 5 in the inside can be taken out.

[0029] A discharge opening 322 is vertically arranged at the bottom of the closing plate 321, the discharge opening 322 completely penetrates the side wall of the closing plate 321, the discharge opening 322 is communicated with the inside space of the material receiving pipe 4, and the discharge opening 322 is used to discharge the impurities in the material receiving pipe 4. A discharge plug 323 is arranged in the inside of the closing plate 321 relative to the discharge opening 322, and the discharge plug 323 seals the discharge opening 322.

[0030] The discharge plug 323 can be opened to discharge the impurities accumulated in the inside of the material receiving pipe 4 to the outside, and the discharge plug 323 can be closed to seal the medium flowing in the inside of the filter housing 1 in the inside, so that the medium does not flow out to the outside.

[0031] The filter screen 5 is arranged above the closing plate 321, and the closing plate 321 is used to tightly fix the filter screen 5, so that the filter screen 5 does not separate from the closing plate 321 when the filter screen 5 flows and intercepts the impurities in the medium in the filter housing 1.

[0032] When the use is completed, the closing plate 321 can be opened to take out the filter screen 5 and install it on other equipment. The bottom of the filter screen 5 is connected to the side of the closing plate 321 close to the edge of the water outlet of the filter housing 1 relative to the discharge opening 322, so that the impurities in the medium intercepted in the filter screen 5 are discharged through the discharge opening 322. The height of the filter screen 5 is not lower than the height of the impurities precipitated in the medium, the filter screen 5 can more conveniently and accurately intercept the impurities precipitated in the medium, and the upper part of the filter housing 1 and the top end of the filter screen 5 always maintain a relative height for the medium to quickly flow from the water inlet to the water outlet, which is not affected by the accumulation of the impurities in the medium intercepted by the filter screen 5.

[0033] The filter screen 5 comprises a front area and a rear area, the front area is located close to the direction of the medium inflow, and the front area is provided with an opening relative to the direction of the medium inflow. In some embodiments, the filter screen 5 is in a hollow cylindrical shape, and the filter screen 5 forms an oblique cut opening in the direction of the medium inflow, and the cut is gradually inclined downward along the direction of the medium outflow to the direction of the medium inflow. The oblique cut opening of the filter screen 5 allows the impurities in the medium to flow into the cylindrical filter screen 5 through the opening, so that the impurities in the medium are accumulated in the filtered inner part by the interception of the filter screen 5, and then discharged from the position of the self-drainage opening 322.

[0034] In operation, the filter is connected to the ship pipeline through the flange, the medium in the ship pipeline flows into the filter from the water inlet, and due to the action of gravity, the impurities in the medium precipitate with the medium flow at the bottom of the pipeline, and when the impurity flow passes through the filter screen 5, it is blocked, and the medium in the pipeline enters the equipment through the filter, and when the equipment debugging is completed, the filter screen 5 of the filter shell 1 can be removed and reused on other filters of the ship, and the filter is installed on the pipeline of the ship as a common pipeline.
