Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a microfiltration water filter. Background Technology

[0002] Shrimp seedlings refer to the juvenile stage of shrimp, which are usually released into aquaculture ponds or waters for cultivation. These seedlings are typically hatched and raised using specialized methods, and the water used for cultivation needs to be replaced in a timely manner to ensure water quality.

[0003] Water is filtered through a filter to remove solids from the water. However, the filter screen needs to be cleaned after a period of use, which causes the equipment to shut down. When the flow rate is high, the cleaning cycle is short, and the process is labor-intensive and inconvenient to use. To address these issues, we propose a microfiltration water filter. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a microfiltration water filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microfiltration water filter, comprising a water pump, a top cover, a filter cartridge, a hydraulic rod, a coarse screen, and a fine screen. The top cover is located above the filter cartridge, and the water pump is connected to the upper end of the top cover. The filter cartridge contains a funnel-shaped coarse screen and a fine screen, with the fine screen fitted over the outer side of the coarse screen. A support ring is located inside the filter cartridge, and the fine screen is fixed to the outer wall of the support ring. The coarse screen is fitted to the upper end of the support ring via a sealing gasket. A drain pipe is located at the lower end of the support ring, and a solenoid valve is installed inside the drain pipe. Hydraulic rods are located at both ends of the filter cartridge.

[0006] Preferably, a first collar is fitted onto the outer wall of the coarse screen, a second collar is fitted onto the outer wall of the fine screen, and a pressure ring is provided on the inner wall of the upper cover at the upper end of the second collar. The combined design of the first collar, the second collar, and the pressure ring fixes the coarse screen with mechanical pressure, preventing the filter screen from shifting due to water flow impact. At the same time, the tight fit between the pressure ring and the collar prevents unfiltered water from leaking out.

[0007] Preferably, the water pump suction end is provided with a suction pipe, and the upper inner wall of the top cover is provided with a guide bucket. The lower opening of the guide bucket is located directly above the coarse filter screen, and the water pump output end is located above the guide bucket. The guide bucket disperses the water flow drawn by the water pump directly above the coarse screen, and effectively transports it into the interior of the coarse screen through the guide bucket.

[0008] Preferably, the lower end of the filter cartridge is provided with a drainage hopper, the lower end of the drainage hopper is provided with a water supply pipe, and one end of the sewage discharge pipe passes through the drainage hopper. The drainage hopper and the water supply pipe form a gravity guiding channel, allowing the filtered clean water to be discharged quickly and reducing stagnation; the sewage discharge pipe passing through the drainage hopper design achieves separation of clean and dirty water, avoiding secondary pollution.

[0009] Preferably, a mating ring is fitted onto the outer wall of the upper cover, and a sealing gasket is provided at one end of the mating ring. The combination of the mating ring and the sealing gasket ensures that there is no gap when the upper cover and the filter cartridge are closed, preventing external substances from entering the filter cartridge through the mating point.

[0010] Preferably, the filter cartridge is equipped with hydraulic rods at both ends, with a rotating seat at the upper end of each hydraulic rod. A rotating shaft is rotatably mounted on the upper end of the rotating seat, and a pressure block is located on one side of the upper end of the mating ring at the upper end of the rotating shaft. The hydraulic rods drive the pressure block through the rotating shaft, applying force to the mating ring, thus avoiding sealing failure caused by unilateral force. The rotating seat design allows for angle adjustment of the pressure block.

[0011] Preferably, the funnel angle between the coarse and fine screens is 60°-75°, and both the coarse and fine screens have annular reinforcing ribs on their outer walls. The 60°-75° funnel angle facilitates water flow, while the reinforcing ribs enhance the fine screen's resistance to deformation and adapt to high water pressure impacts.

[0012] Preferably, the inner wall of the drain hopper is coated with a nano-hydrophobic coating, which extends to the inlet of the water supply pipe. The nano-hydrophobic coating reduces water residue, prevents the adhesion and growth of microbial films, and reduces the frequency of cleaning.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In use, this utility model uses a water pump to draw in raw water for shrimp fry farming and deliver it into the filter cartridge. Large solid particles are screened through a coarse screen, and then smaller solid particles are screened through a fine screen. The filtered water is then discharged, realizing the filtration process for shrimp fry farming water. During this process, both the fine and coarse screens are funnel-shaped, with the fine screen fitted over the coarse screen. This results in a large filtration area for the raw water, and the intercepted solids accumulate continuously at the bottom. Large solids can be automatically discharged periodically through the drain pipe. Solid particles accumulate more slowly inside the fine screen, greatly extending the maintenance cycle of the filter elements, reducing manual labor, and making the microfilter easy to use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a microfiltration water filter, including a water pump 2, an upper cover 3, a filter cylinder 4, a hydraulic rod 8, a coarse screen 12 and a fine screen 13. The upper cover 3 is provided above the filter cylinder 4, and the water pump 2 is connected to the upper end of the upper cover 3. The filter cylinder 4 is provided with a funnel-shaped coarse screen 12 and a fine screen 13. The fine screen 13 is sleeved on the outside of the coarse screen 12. The filter cylinder 4 is provided with a support ring 10. The fine screen 13 is fixed to the outer wall of the support ring 10. The coarse screen 12 is fitted to the upper end of the support ring 10 through a sealing gasket. The lower end of the support ring 10 is provided with a drain pipe 7, and a solenoid valve 11 is provided inside the drain pipe 7.

[0023] The outer wall of the coarse screen 12 is fitted with a collar 16, the outer wall of the fine screen 13 is fitted with a collar 17, and the inner wall of the top cover 3 is provided with a pressure ring 15 located at the upper end of the collar 17.

[0024] The water pump 2 is equipped with a suction pipe 1 at the suction end, and a guide bucket 14 is provided on the inner wall of the upper end of the top cover 3. The lower opening of the guide bucket 14 is located directly above the coarse filter screen, and the output end of the water pump 2 is located above the guide bucket 14.

[0025] The funnel angle between the coarse screen 12 and the fine screen 13 is 60°-75°, and the outer walls of both the coarse screen 12 and the fine screen 13 are provided with annular reinforcing ribs.

[0026] Based on the implementation steps of Example 1: Pump 2 draws the water to be treated into the top cover 3, and the water is evenly dispersed onto the surface of the coarse screen 12 via the guide bucket 14. Large particles of impurities are intercepted. The pre-filtered water flows to the fine screen 13, where tiny suspended solids are retained. The clean water passes through the fine screen 13 and enters the drain bucket 5, then is transported to the next processing step via the water delivery pipe 6. It is worth noting that the coarse screen 12 (1-2 mm aperture) and the fine screen 13 (50-100 μm aperture) are nested together, using an inner and outer nested funnel-shaped design. The coarse screen 12 intercepts large particles of impurities. The fine screen 13 filters out small suspended solids such as feces and bacterial films, forming a two-level physical barrier to improve water purification efficiency. It specifically removes pollutants of different particle sizes, solving the problems of easy clogging and insufficient filtration precision of traditional single-layer filters. The solids filtered by the coarse screen 12 are discharged through the drain pipe 7, avoiding manual cleaning of the coarse screen 12 in the short term. At the same time, the fine screen 13 can be cleaned by opening the top cover 3. The fine screen 13 has a large filtration area and a long cleaning cycle. The automatic sewage discharge function of the coarse screen 12 can reduce labor costs, thus making the filtration device convenient to use.

[0027] like Figures 1-5 As shown, compared with Embodiment 1, the microfiltration water filter proposed in this utility model further includes: hydraulic rods 8 at both ends of the filter cylinder 4, a drainage hopper 5 at the lower end of the filter cylinder 4, a water supply pipe 6 at the lower end of the drainage hopper 5, and a sewage pipe 7 penetrating the drainage hopper 5 at one end.

[0028] The outer wall of the top cover 3 is fitted with a mating ring 9, and a sealing gasket is provided at one end of the mating ring 9;

[0029] Hydraulic rods 8 are provided at both ends of the filter cartridge 4. A rotating seat 18 is provided at the upper end of the hydraulic rod 8. A rotating shaft 19 is rotatably mounted on the upper end of the rotating seat 18. A pressure block 20 is provided on one side of the upper end of the docking ring 9 at the upper end of the rotating shaft 19.

[0030] The inner wall of the drainage hopper 5 is coated with a nano-hydrophobic coating, and the hydrophobic coating of the drainage hopper 5 extends to the inlet of the water supply pipe 6.

[0031] In this embodiment, after the top cover 3 is connected to the filter cartridge 4, the connecting ring 9 fits together. Then, the pressure block 20 is rotated and rotated to be located on the connecting ring 9. The longitudinal force of the hydraulic rod 8 is applied through the pressure block 20 to squeeze the connecting ring 9, and the connecting ring 9 fits tightly together. At the same time, the pressure ring 15 applies pressure to the first collar 16 and the second collar 17, so that the lower end of the coarse filter screen fits on the support ring 10, realizing the installation of the microfilter and avoiding the installation of parts. The microfilter is easy to disassemble and assemble, and provides convenience for maintenance.
