Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a quick-release, easy-to-clean pre-cyclone separator filter with a filter screen. Background Technology

[0002] Filters are used to remove suspended solids, particulate matter, and other impurities from water or industrial fluids. Different filter structures are required for different filtration needs. Natural water sources, such as well water, river water, and spring water, usually contain a large amount of suspended solids, such as silt, algae, and plant debris. If these suspended solids directly enter subsequent fine filtration or membrane treatment systems, they will quickly cause clogging, increase maintenance frequency, and shorten equipment life.

[0003] Therefore, there is an urgent need for a quick-release and easy-to-clean pre-cyclone separator filter with a filter screen, which can be used as a pre-filtration device in conjunction with an ultrafiltration filter to reduce the clogging of the ultrafiltration filter. Utility Model Content

[0004] To address the problem of ultrafiltration filters clogging when filtering natural water sources containing a large amount of suspended solids.

[0005] This utility model provides a quick-release, washable pre-cyclone separator filter with a filter screen, including a cylindrical tank, a funnel, an overflow pipe, an inlet elbow, and a chuck cover. The top of the cylindrical tank has a chuck-type overflow port, and the bottom of the cylindrical tank has a drain port. The funnel is located in the middle of the interior of the cylindrical tank, separating the cylindrical tank into a cyclone chamber and a sludge collection chamber. The bottom of the funnel has a funnel opening, and the cyclone chamber, funnel opening, and sludge collection chamber are interconnected. The overflow pipe is located at the top of the cylindrical tank and communicates with the chuck-type overflow port. The interior of the overflow pipe... It is equipped with a filter screen; the water inlet elbow is located at the top of the round tank, and the water inlet elbow and the overflow pipe are on the same horizontal plane; the chuck cover is connected to the chuck overflow port, and the chuck cover has a water outlet; pressurized water enters from the water inlet elbow, changes the direction of water flow and forms a water vortex, and the particles in the water flow along the side wall of the vortex chamber, through the funnel opening, into the sludge collection chamber, and finally discharged through the sludge outlet under the action of the centrifugal force of the water vortex; the centrifuged water is filtered through the filter screen of the overflow pipe and flows out from the water outlet.

[0006] Preferably, there are two water inlet elbows, which are centrally symmetrically fixed to both sides of the top of the round tank.

[0007] Preferably, a quick-release pre-cyclone separator filter with a filter screen also includes a clamp for locking the chuck cover and the chuck-type overflow port.

[0011] Preferably, the drain outlet and the funnel opening are located on the same straight line.

[0012] The beneficial effects of this invention are as follows: Compared to existing single filters, the design divides the filter into two areas—a cyclone chamber and a sludge collection chamber—by a cylindrical tank, providing a larger processing capacity, optimizing the solid-liquid separation process, and facilitating more thorough removal of large particles. The funnel design enhances the stability of the water cyclone formation, improving separation efficiency. The filter screen in the overflow pipe further filters fine particles, helping to protect downstream equipment.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Reference Figures 1-3A quick-release, washable pre-cyclone separator filter with a filter screen includes a cylindrical tank 2, a funnel 4, an overflow pipe 6, an inlet elbow 7, and a chuck cover 11. The top of the cylindrical tank 2 has a chuck-type overflow port 8, and the bottom of the cylindrical tank 2 has a drain port 1. The funnel 4 is located in the middle of the interior of the cylindrical tank 2, dividing the cylindrical tank 2 into a cyclone chamber 5 and a sludge collection chamber 3. The bottom of the funnel 4 has a funnel opening 13, and the cyclone chamber 5, the funnel opening 13, and the sludge collection chamber 3 are interconnected. The overflow pipe 6 is located at the top of the cylindrical tank 2 and communicates with the chuck-type overflow port 8. The interior of the overflow pipe 6 is... There is a filter screen 9; the water inlet elbow 7 is located on the top of the round tank 2, and the water inlet elbow 7 and the overflow pipe 6 are located on the same horizontal plane; the chuck cover 11 is connected to the chuck overflow port 8, and the chuck cover 11 is provided with a water outlet 14; pressurized water enters from the water inlet elbow 7, and changes the direction of water flow and forms a water vortex through the water inlet elbow 7. Under the action of centrifugal force of the water vortex, the particles in the water flow along the side wall of the vortex chamber 5, through the funnel opening 13, enter the sludge collection chamber 3, and finally are discharged through the sludge discharge port 1; the centrifuged water is filtered through the filter screen 9 of the overflow pipe 6 and flows out from the water outlet 14.

[0019] Compared to existing single filters, the design divides the filter into two areas—a cyclone chamber 5 and a sludge collection chamber 3—by a cylindrical tank 2, providing a larger processing capacity, optimizing the solid-liquid separation process, and facilitating more thorough removal of large particles. The funnel 4 enhances the stability of the water vortex formation, improving separation efficiency. The filter screen 9 in the overflow pipe 6 further filters fine particles, protecting downstream equipment. Compared to traditional direct water inlet methods, the inlet elbow 7 design creates a cyclone effect, improving particle separation efficiency. The chuck cover 11 facilitates connection to downstream equipment and allows for the extraction of filtered water. This design solves the problem of ultrafiltration filter clogging caused by filtering natural water sources containing large amounts of suspended solids.

[0020] In some embodiments, there are two water inlet elbows 7, which are centrally symmetrically fixed to both sides of the top of the round tank 2.

[0021] Reference Figures 2-3 Two inlet elbows 7 simultaneously introduce water flow, creating a counter-current effect that enhances the rotation intensity of the water within the cyclone chamber 5. This symmetrical inlet design generates a stronger centrifugal force within the cyclone chamber 5, effectively pushing larger particles against the sidewalls and ultimately into the sludge collection chamber 3. Furthermore, the dual-sided inlet increases the volume of water processed per unit time. In addition, the centrally symmetrical design of the inlet elbows 7 ensures that water enters the cyclone chamber 5 evenly from both sides, avoiding the flow deviation that might occur with unilateral inlet flow and guaranteeing a balanced distribution of water throughout the filter.

[0022] In some embodiments, a quick-release pre-cyclone separator filter with a filter screen also includes a clamp 12 for locking the chuck cover 11 and the chuck overflow port 8.

[0023] Reference Figures 2-3 The clamp 12 applies pressure evenly to ensure a tight fit between the chuck cover 11 and the chuck overflow port 8, effectively preventing water leakage from the interface. Furthermore, the clamp 12 makes the installation and removal of the chuck cover 11 very simple and quick; simply loosening or tightening the clamp 12 completes the operation, greatly reducing maintenance time.

[0024] In some implementations, the drain outlet 1 is connected to a valve. By periodically opening the valve, particles in the water are discharged from the drain outlet 1.

[0025] In some embodiments, a sealing ring 10 is provided between the chuck cover 11 and the chuck overflow port 8.

[0026] Reference Figure 3 The sealing ring 10 acts as a buffer layer between the direct contact surfaces of the chuck cover 11 and the chuck-type overflow port 8, effectively filling tiny gaps and ensuring that water or gas does not leak from the interface. The design of the sealing ring 10 combined with the clamp 12 makes the connection between the chuck cover 11 and the chuck-type overflow port 8 more secure, while not affecting quick assembly and disassembly.

[0027] In some embodiments, the filter screen 9 is wound into a cylindrical shape and disposed inside the overflow pipe 6. The filter screen 9 and the overflow pipe 6 are coaxially arranged, and the length of the filter screen 9 is greater than the length of the overflow pipe 6.

[0028] Reference Figure 3 Compared to flat filter discs, the cylindrical filter screen 9 provides a larger filtration surface area, allowing water to flow more evenly through it and enabling a greater volume of water to pass through per unit time, thus improving filtration capacity and efficiency. The filter screen 9 is coaxially arranged with the overflow pipe 6, ensuring that the water flow is evenly distributed on the filter screen 9 upon entering the overflow pipe 6, avoiding flow deviation and guaranteeing a stable filtration effect. Furthermore, it facilitates the removal and installation of the filter screen 9, as it can be easily pulled out or inserted from one end of the overflow pipe 6. The length of the filter screen 9 is greater than the length of the overflow pipe 6 to ensure that all water entering the overflow pipe 6 is filtered by the filter screen 9.

[0029] In some implementations, the drain outlet 1 and the funnel outlet 13 are located on the same straight line.

[0030] Reference Figure 2 or Figure 3 The straight path reduces water flow resistance and energy loss, ensuring smoother particle transport. Because particles can directly enter the drain outlet 1 through the funnel opening 13 along the straight path, particle deposition in the collection bin 3 is reduced, making cleaning simpler and faster.
