Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to an integrated seawater filtering device capable of self-cleaning. Background Art

[0002] As my country continues to increase its efforts in developing marine resources, the technical equipment of marine platforms has gradually improved. Seawater filters, as key equipment for purifying seawater in the fields of desalination, marine fisheries, aquariums, etc., have broad application prospects.

[0003] Seawater filters, a crucial piece of equipment for seawater purification, are often installed onboard ships. However, due to limited space onboard ships, conventional seawater filtration equipment is bulky and occupies a significant amount of space, reducing the actual usable area of ​​the ship. Furthermore, after prolonged use, the filter components within the seawater filter are prone to retaining large amounts of impurities and dirt, significantly reducing seawater filtration efficiency and increasing the labor intensity of the equipment. Prior art publication No. CN 114225503A discloses a seawater filter that addresses the issue of limited space onboard ships. However, the filter screen is difficult to remove for cleaning, and the outer and inner filter cylinders must be frequently disassembled, resulting in lengthy disassembly times and hindering rapid maintenance and cleaning.

[0004] Therefore, the above problems need to be solved urgently. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the utility model provides a self-cleaning integrated seawater filter device. The purpose is to realize the automatic cleaning operation of the seawater filter device through the integrated setting of the filter body and the backwash pump. The device has a simple structure, convenient operation, small space occupation and good cleaning effect.

[0006] To achieve the above-mentioned objectives, the present invention provides a self-cleaning integrated seawater filtration device, comprising a filter body, a backwash pump, an inlet pipe, an outlet pipe, and a solenoid valve; the filter body and the backwash pump are fixedly mounted on a base; the filter body and the backwash pump are integrally arranged; the backwash pump is designed for an electric cleaning mode; a water inlet is tangentially provided on the top of the filter body away from the backwash pump, the water inlet being connected to the inlet pipe; a water outlet is provided on the filter body opposite the inlet, the water outlet being connected to the outlet pipe; a solenoid valve is provided on the outlet pipe, the solenoid valve controlling the water outflow from the outlet pipe; a filter element for filtering seawater is provided within the filter body. The present invention realizes the electric backwashing operation of the seawater filtration device through the coordinated arrangement of the filter body, the backwash pump, and the solenoid valve; when the electric cleaning mode is turned on, the solenoid valve is closed, the backwash pump is turned on, and the backwash pump electrically cleans the seawater filtration device and the filter element. Through the coordinated setting of the water inlet and the water outlet, seawater can enter and exit the filter body. The seawater entering the filter body from the water inlet pipe is filtered out of solid particles, mud and other impurities through the filter element, and the purified seawater that meets the standards flows out from the water outlet pipe.

[0007] Preferably, a drain port is tangentially provided at the bottom of the filter body; the drain port is connected to a drain pipe. Impurities such as solid particles and sludge after filtering the seawater, and attached matter dropped after the backwash pump cleans the filter element, flow out through the drain port and are discharged into a sewage collection tank through the drain pipe.

[0008] Preferably, the outlet end of the sewage pipe is provided with a sewage valve, which controls the discharge, and sewage is discharged in time after the sewage valve is opened.

[0009] Preferably, a drain plug is detachably provided on the filter body near the drain outlet. When the drain plug is opened, sewage can flow out of the drain outlet.

[0010] Preferably, a filter is provided at the inlet end of the water inlet pipe to initially filter out large particles and other impurities in the seawater, thereby preventing large particles from entering the seawater filtration device and clogging the filter element, thereby deteriorating the filtration performance.

[0011] Preferably, a water inlet valve is provided near the inlet end of the water inlet pipe, which controls the inflow of seawater, and is opened when the seawater filtering device is in the filtering state.

[0012] Preferably, a generator is provided on the outlet pipe near one end of the solenoid valve. When the generator is operating, current flows through the coil inside the solenoid valve, generating a magnetic force that attracts the valve core inside the solenoid valve to move, and the solenoid valve is in an open state, allowing seawater to flow out of the outlet pipe. When the generator is powered off, the solenoid valve closes.

[0013] Preferably, the outlet end of the outlet pipe is connected to an anti-siphon pipe; the anti-siphon pipe is at a higher level than the outlet pipe; and a retractable anti-siphon vent is provided at the top of the anti-siphon pipe. When the seawater filtration device stops working, the anti-siphon vent is opened, and the anti-siphon pipe is connected to the atmosphere. The anti-siphon pipe breaks the vacuum condition in the outlet pipe, effectively preventing the backflow of seawater after passing through the outlet pipe. When the seawater filtration device is working, the anti-siphon vent is closed, and the seawater can be discharged normally.

[0014] Preferably, a sensor is provided on the water outlet pipe near one end of the anti-siphon pipe. When the water inlet valve is closed, the sensor senses that the water supply to the seawater filtration device has stopped, and at this time the sensor transmits a power-off signal to the generator. After receiving the signal, the generator is powered off and the solenoid valve is closed.

[0015] Preferably, the top of the filter body is further provided with an openable and closable top cover. When the seawater filter device needs to be cleaned manually, the top cover can be opened after the power is turned off, the filter element can be taken out, and the filter element can be manually cleaned or checked.

[0016] Beneficial effects

[0017] This utility model integrates the filter body and backwash pump to achieve automatic cleaning of the seawater filtration device. When the electric cleaning mode is activated, the solenoid valve is closed, and the backwash pump is activated, electrically cleaning the seawater filtration device and filter element. The device features a simple structure, convenient operation, a small footprint, and excellent cleaning performance.

[0018] Through the coordinated setting of sensors, generators, solenoid valves and water inlet valves, when the water inlet valve is closed, the sensor senses that the water supply to the seawater filtration device has stopped. At this time, the sensor transmits the power-off signal to the generator. After receiving the signal, the generator cuts off the power and the solenoid valve closes, realizing real-time detection function.

[0019] The utility model provides two optional cleaning modes: electric cleaning mode and manual cleaning mode. The filter element is easy to clean, flexible in design and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
