Description

Technical Field

[0001] The invention relates to the technical field of ship pipelines, in particular to a self-cleaning and anti-clogging device for ship pipelines. Background Art

[0002] With the continuous advancement of ship engineering technology, the ship's cooling system plays a vital role in the stable operation of ship power units and equipment. Modern ships generally use seawater as a cooling medium, and the heat of the engine or other mechanical equipment is removed through the seawater cooling system to maintain its normal operating temperature. The seawater cooling system usually includes seawater filters, pipes, pumps, radiators and other components, among which the seawater filter plays a key role in filtering impurities, particles and biological substances in seawater.

[0003] In the ship cooling water piping system, the seawater filter is located at the water inlet end of the system and is usually installed in the seawater pipeline. It is responsible for removing suspended matter, silt, seaweed, shellfish and other harmful substances in the seawater entering the cooling system. Through filtration, the seawater can maintain a high degree of cleanliness, thereby preventing these impurities from clogging the pipes, damaging pumps and other equipment after entering the cooling system, thereby ensuring the efficient and stable operation of the cooling system. However, since seawater generally contains a large amount of impurities such as suspended particles, algae and microorganisms, these substances are easy to accumulate and deposit on the front side of the seawater filter, especially the pipe part on the front side of the filter. Over time, these sediments will gradually accumulate on the inner wall of the pipe, causing the inner diameter of the pipe to decrease, the water flow resistance to increase, and even cause the pipe or filter to be completely blocked. This not only reduces the working efficiency of the cooling system, but may also cause serious equipment failures and affect the normal operation of the ship.

[0004] In order to prevent the blockage of the front part of the seawater filter, the traditional method usually relies on manual cleaning or regular replacement of the filter medium in the filter. Although these measures can solve the problem to a certain extent, they often require a lot of manual intervention and cannot effectively deal with the continuous accumulation of impurities. In addition, the manual cleaning operation may also affect the ship's navigation plan and increase the workload of the crew. For this reason, those skilled in the art have proposed a self-cleaning and anti-blocking device for ship pipelines to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1 and attached Figure 2 The embodiment of the present invention provides a self-cleaning and anti-clogging device for ship pipelines, including a filter 1, the right side of the filter 1 is connected to a seawater pipeline 2 through a connecting flange 7, and four filter plates 3 are installed inside the filter 1.

[0023] Specifically, the filter 1 is the core part of the device, which is usually made of high-strength, corrosion-resistant materials such as stainless steel or copper alloy, and can resist the corrosion of seawater and high-pressure water flow. A plurality of filter plates 3 are installed inside the filter 1. The filter plates are made of stainless steel mesh or plastic woven materials, and can effectively filter impurities such as suspended matter, silt, seaweed and microorganisms in the seawater. The filter plates 3 have a certain filtering accuracy to ensure the cleanliness of the seawater and prevent impurities from entering the subsequent pipeline and cooling system. A seawater pump is connected to the left side of the filter 1, which is the power source in the cooling system. The seawater pipeline 2 is made of highly corrosion-resistant and anti-aging marine engineering materials (such as polyethylene or fiberglass) to ensure long-term stable operation in a seawater environment. The seawater pipeline and the filter 1 are fixedly connected by a connecting flange 7 to ensure a tight connection between the pipeline and the filter 1 to prevent water leakage.

[0024] Please refer to the attached Figure 2 -Attached Figure 4 A self-cleaning component 4 is provided inside the seawater pipeline 2, which is used to self-clean the internal pipeline of the filter 1 and the outside of the first filter plate 3; the self-cleaning component 4 includes a fixing ring 401, which is fixedly connected to the inside of the seawater pipeline 2, and arc blocks 402 are fixedly connected to the left and right sides of the inner wall of the fixing ring 401, and a fixing block 403 is fixedly connected to the inside of the fixing ring 401. The inside of the fixing block 403 is rotatably connected to an impeller 404, and the left side of the impeller 404 is fixedly connected to a rotating shaft 405. A plurality of connecting rods 406 are fixedly connected to the front and rear sides of the outside of the rotating shaft 405, and the outside of the connecting rods 406 on the front and rear sides and the left side of the rotating shaft 405 are fixedly connected to a mounting block 407. A cleaning piece 408 is slidably connected to the inside of the mounting block 407, and the outside of the cleaning piece 408 abuts against the inner wall of the filter 1 and the outside of the outer filter plate 3.

[0025] Specifically, the self-cleaning component 4 is the key to realize the automatic cleaning of the pipeline and the filter. The component includes a fixing ring 401, an arc block 402, a fixing block 403, an impeller 404, a rotating shaft 405, a connecting rod 406, a mounting block 407 and a cleaning piece 408. The fixing ring 401 is fixed inside the seawater pipeline to play a supporting and fixing role to ensure the stable operation of the entire self-cleaning component. The arc block 402 is arranged on both sides of the fixing ring 401 to guide the water flow to rotate the impeller 404 and reduce the impact force of the water flow to avoid excessive pressure on the fixing ring caused by the water flow impact. The impeller 404 drives the rotating shaft 405 to rotate. Through the connecting rod 406 outside the rotating shaft 405, after the impeller 404 drives the rotating shaft 405 to rotate, the connecting rod 406 can be driven to rotate. The outside of 406 and the outside of the rotating shaft 405 are fixedly connected with a mounting block 407, so that the mounting block 407 can be driven to rotate through the connecting rod 406 and the rotating shaft 405, and a cleaning piece 408 is slidably connected to the inside of the mounting block 407, so that the cleaning piece 408 can be driven to clean the impurities on the inner wall of the pipeline of the filter 1 and the outside of the external filter plate 3 to keep the pipeline unobstructed. The cleaning piece 408 is usually made of a material with good wear resistance such as stainless steel or a polymer synthetic material, which can efficiently remove attachments on the inner wall of the pipeline without damaging the inner wall of the filter 1 and the filter plate 3; its structural design ensures that during the flow of seawater, the impeller 404 rotates with the flow of seawater, driving the rotating shaft 405 and the cleaning piece 408 to rotate, thereby cleaning the sediments on the internal pipeline of the filter 1 and the outside of the filter plate 3.

[0026] Please refer to the attached Figure 4 -Attached Figure 6 An adaptive component 5 is arranged inside the self-cleaning component 4, which is used to tightly fit the cleaning component 408 with the internal pipeline of the filter 1 and the first layer of filter plate 3; the adaptive component 5 includes a plurality of limit grooves 501, and the plurality of limit grooves 501 are all opened inside the mounting block 407, and a spring 502 is arranged inside the limit groove 501, and the internal sliding connection of the limit groove 501 is a limit block 503.

[0027] Specifically, the adaptive component 5 is used to ensure that the cleaning piece 408 is in close contact with the inner wall of the filter 1 pipe and the first layer of filter plate 3, so as to maximize the cleaning effect. The main components of the adaptive component 5 are the limit groove 501, the limit block 503, the connecting rod 504 and the spring 502, etc. The limit groove 501 is equipped with a spring 502 and a limit block 503. These components can be adaptively adjusted according to the water flow and impurity deposition during the cleaning process, so that the cleaning piece 408 can more effectively fit the inner wall of the filter 1 pipe and the filter plate 3. The connecting rod 504 is used to connect the limit block 503 and the cleaning piece 408 to ensure that the cleaning piece 408 can move with the adjustment of the limit block 503. A sealing ring is provided at the connection between the connecting rod 504 and the mounting block 407, and the connecting rod 504 is made of corrosion-resistant and wear-resistant material; the adaptive component 5 can be automatically adjusted according to the actual situation of the inner wall of the pipe to ensure that the cleaning piece 408 always maintains an effective cleaning state.

[0028] Please refer to the attached Figure 2 and attached Figure 7 A backwashing assembly 6 is provided at the bottom of the filter 1, which is used to backwash the interior of the filter 1 to prevent clogging. The backwashing assembly 6 includes a connecting pipe 601, which is fixedly connected to the bottom of the filter 1, and the position of the connecting pipe 601 is on the left side of the filter plate 3. The bottom of the connecting pipe 601 is fixedly connected to a water tank 602, and the lower right side of the water tank 602 is fixedly connected to a connecting pipe 2 603, and the upper right side of the water tank 602 is fixedly connected to a pressure pump 604. The top of the connecting pipe 2 603 is fixedly connected to the input end of the pressure pump 604, and the output end of the pressure pump 604 is fixedly connected to a delivery pipe 605.

[0029] Specifically, the backwashing assembly 6 is installed at the bottom of the filter 1, and is mainly used to regularly backwash the inside of the filter 1 to prevent long-term accumulation of impurities. The backwashing assembly includes a water tank 602, a pressure pump 604, a connecting pipe 601 and a solenoid valve 607-610, etc. The connecting pipe 1 601 is fixedly connected to the bottom of the filter 1 and is located on the left side of the filter plate 3. It plays the role of connecting the filter 1 with the water tank 602, and can replenish water to the water tank 602. The water tank 602 stores cleaning water, and when needed, the water is sent into the filter through the pressure pump 604 for backwashing. The connecting pipe 2 603 connects the water tank 602 with the pressure pump 604 to ensure that the water source can be smoothly delivered to the pressure pump 604. The pressure pump 604 is responsible for providing sufficient water pressure to ensure that the backwashing process can effectively remove the impurities accumulated in the filter 1. The delivery pipe 605 pressurizes the pressure pump 604 The backwashing water is delivered to the bottom of the filter 1 to start the backwashing function and flush the impurities in the filter 1. The drain pipe 606 is located on the right side of the filter 1 and is responsible for discharging the impurities and water removed during the backwashing process. The solenoid valve 1 607 is arranged inside the filter 1 to control the water flow inside the filter 1 to ensure that the backwashing function of the filter 1 can be started as needed. The solenoid valve 3 609 is arranged inside the delivery pipe 605 to control the delivery process of the pressurized water flow to ensure that the high-pressure water can smoothly flow into the filter 1.

The battery valve 2 608 is arranged inside the seawater pipeline 2 to control the flow rate and water pressure in the seawater pipeline 2. The solenoid valves 607-610 control the water flow direction and the backwashing process through the central control system to ensure that the impurities in the filter 1 can be effectively removed.

[0030] Please refer to the attached Figure 2 , Attachment Figure 7 and attached Figure 8 A water flow sensor 611 is installed inside the filter 1, and the water flow sensor 611 transmits the collected data to the central control system. The central control system includes: an acquisition module: which is used to transmit the data collected by the water flow sensor 611 to the central control system; an analysis module: which analyzes the data collected in the central control system through a data processing unit; a driving module: which drives the pressure pump 604, solenoid valve 1 607, battery valve 2 608, solenoid valve 3 609 and solenoid valve 4 610 through the analyzed information.

[0031] Specifically, the water flow sensor 611 is installed inside the filter to monitor the flow rate and pressure of the water flow in real time.

The central control system includes an acquisition module, an analysis module and a drive module. The acquisition module is responsible for obtaining the data of the water flow sensor; the analysis module analyzes the working status of the filter according to the data; the drive module automatically adjusts the pressure pump, solenoid valve and other components according to the analysis results to ensure the smooth operation of self-cleaning and backwashing.

[0032] Working principle: First, the seawater cooling system in the ship is started, so that the seawater enters the filter 1 through the seawater pipe 2 and is filtered by the filter plate 3 to dissipate heat for the engine; At the same time, the flow of seawater drives the impeller 404 to rotate, and then drives the rotating shaft 405 to rotate, thereby driving the connecting rod 406 to rotate, and then drives the mounting block 407 on the left side of the rotating shaft 405 and the mounting block 407 on the connecting rod 406 to rotate therewith, so that the inner wall of the filter 1 pipeline and the outer filter plate 3 are self-cleaned by the cleaning member 408 in the mounting block 407 to prevent the pipeline from being blocked; Secondly, through the elastic effect of the spring 502 installed in the limit groove 501 in the mounting block 407, the limit block 503 can be driven to move outward, thereby driving the connecting rod 504 to drive the cleaning member 408 to fit closely with the inner wall of the pipeline and the outside of the filter plate 3, so that automatic adjustment can be made according to actual conditions to ensure that the cleaning member 408 always maintains an effective cleaning state; Finally, when impurities accumulate to a certain extent, the water flow sensor 611 will detect the flow change and automatically start the backwash process through the central control system, by closing solenoid valve 1 607 and solenoid valve 2 608, opening solenoid valve 3 609 and solenoid valve 4 610, and starting the pressure pump 604 to draw water from the water tank 602, and transport the water to the filter 1 through connecting pipe 2 603 and delivery pipe 605, thereby flushing the filter plate 3 and the inner wall of the pipeline, and discharging impurities from the system through the drain pipe 606 to ensure that the filter is always in the best clean state.
