Description

Technical Field

[0001] This utility model relates to a filtration device, specifically a low-resistance multi-directional water vortex filtration device that is easy to install, has good filtration effect, low resistance and low energy consumption, and flexible outlet position installation. Background Technology

[0002] In heating, air conditioning, and industrial circulating water systems, liquid transport systems require filtration devices to remove impurities (such as silt, rust, and large particles) to protect downstream pumps, heat exchangers, valves, and other equipment, preventing pipe blockage or equipment wear. Currently, Y-type filters are the most commonly used filtration equipment in the industry, but these filters have the following significant drawbacks: 1. Poor installation adaptability: The outlet direction of the Y-type filter is fixed and cannot be flexibly adjusted according to the site space layout. When the installation environment is limited (such as dense pipes and narrow space), additional elbows or reducers are required, which increases the installation complexity and cost.

[0003] 2. High system energy consumption: The Y-type filter has a small cavity volume and a fast water flow velocity (usually ≥1.5m / s), resulting in a large resistance loss (generally ≥30kPa). A higher head water pump is required to match the system, which not only increases the equipment purchase cost, but also increases the long-term operating energy consumption.

[0004] 3. Short filter life: Water flow directly impacts the filter, and large particles of impurities easily adhere to the filter surface and rub against it repeatedly, causing the filter to wear out too quickly, with an average replacement cycle of only 3-6 months.

[0005] 4. High equipment and maintenance costs: Traditional Y-type filters require each water pump to be equipped separately, resulting in a large total equipment purchase volume; and maintenance requires stopping the machine for disassembly, which not only affects the continuous operation of the system, but also requires frequent investment in labor and spare parts costs.

[0006] 5. Limited filtration efficiency: Relying on a single filter screen, large particles can easily clog the filter screen pores, resulting in unstable filtration accuracy, and some fine impurities may still enter the downstream system.

[0007] Furthermore, while existing cyclone filtration devices can initially separate impurities through centrifugal force, they suffer from problems such as non-adjustable outlet direction, insufficient secondary filtration accuracy, and poor control of resistance loss, making it difficult to meet diverse on-site needs. To address the shortcomings of the existing technology, there is an urgent need for a filtration device that is flexible to install, has low resistance, long lifespan, and low cost. Utility Model Content

[0008] To address the aforementioned problems, the main objective of this utility model is to provide a low-resistance multi-directional cyclone filtration device that is easy to install, has good filtration effect, low resistance and low energy consumption, and flexible outlet position installation.

[0009] This utility model solves the above-mentioned technical problems through the following technical solution: a low-resistance multi-directional water cyclone filter device, the low-resistance multi-directional water cyclone filter device comprising: an upper cylinder, a lower cylinder, an inner cylinder, a filter screen, fasteners, an exhaust valve seat, and an automatic exhaust valve.

[0010] The upper cylinder and the lower cylinder are detachably connected and fixed by fasteners. An inner flange ring for mounting the inner barrel is provided in the upper or lower cylinder. The inner barrel is detachably mounted on the flange ring. The filter screen is detachably mounted on the upper end of the inner barrel. The exhaust valve seat is provided at the top of the upper cylinder, and the automatic exhaust valve is mounted on the exhaust valve seat. A drain hole is provided at the bottom of the lower cylinder.

[0011] The upper cylinder is equipped with a water inlet, and the lower cylinder is equipped with a water outlet. Both the upper and lower cylinders are equipped with outer flanges. The circumferential positions of the upper and lower cylinders are adjusted by the outer flanges, thereby adjusting the angle between the water inlet and the water outlet.

[0012] In a specific embodiment of this utility model, the inner barrel is fixed to a flange ring provided inside the upper or lower barrel by locking screws.

[0017] The positive and progressive effects of this utility model are as follows: The high and low resistance multi-directional water cyclone filter device provided by this utility model has the following advantages: High-precision filtration: Two-stage filtration (cyclone separation + 40-mesh filter) ensures stable filtration accuracy and effectively removes impurities with a particle size ≥100μm, protecting downstream equipment for safe operation.

[0018] Long lifespan: Large particles are separated in advance through the first stage of cyclone filtration, preventing them from impacting the filter screen.

Low-head water pumps can be selected, reducing operating energy consumption by 15%-20%.

[0020] Low cost: Only one unit needs to be installed in the main system pipe to meet the needs (no need to equip each water pump separately), reducing equipment procurement costs by about 20%; and no downtime maintenance is required, extending the maintenance cycle to 12-18 months, reducing maintenance costs by 70%.

[0021] Easy installation: The outlet is adjustable in multiple directions and has a flat inlet and outlet structure, which is suitable for more than 95% of on-site installation scenarios, reducing the amount of pipe fittings used and improving installation efficiency by 50%.

Unstable filtration accuracy and efficiency. To solve the above technical problems, the technical solution adopted by this utility model is as follows: Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a top view of the present invention, as shown below. Figure 1-2 As shown: This utility model proposes a low-resistance multi-directional water cyclone filter device, which includes: an upper cylinder 1, a lower cylinder 4, an inner cylinder 6, a filter screen 11, fasteners 2, an exhaust valve seat 12, and an automatic exhaust valve 13.

An inner flange ring for mounting the inner barrel 6 is provided inside the upper cylinder 1 or the lower cylinder 4. The inner barrel 6 is detachably mounted on the flange ring. The filter screen 11 is detachably mounted on the upper end of the inner barrel 6. An exhaust valve seat 12 is provided on the top of the upper cylinder 1. An automatic exhaust valve 13 is mounted on the exhaust valve seat 12.

Both the upper cylinder 1 and the lower cylinder 4 are provided with an outer flange ring. The circumferential position of the upper cylinder 1 and the lower cylinder 4 is adjusted by the outer flange ring, thereby adjusting the angle between the water inlet 3 and the water outlet 5.

[0029] In the specific implementation process, the inner barrel 6 is fixed to the flange ring provided inside the upper barrel 1 or the lower barrel 4 by locking screws 10.

[0030] In the specific implementation process, the filter screen 11 and the inner barrel 6 are fixed together by locking screws 10.

[0031] In the specific implementation process, fastener 2 adopts a combination of bolts, nuts and washers.

[0032] An O-ring groove is provided on the surface where the upper cylinder 1 and the lower cylinder 4 meet, and a sealing O-ring 9 is provided in the O-ring groove to achieve a seal between the upper cylinder 1 and the lower cylinder 4; the filter screen 11 can generally be selected as 40 mesh, and can be detachably installed on the upper end of the inner cylinder 6 and fixed by locking screws 10; the upper cylinder 1 and the lower cylinder 4 are connected and fixed by fasteners 2, which can be selected as M20x70 bolts, M20 nuts and PJ20 washers; the exhaust valve seat 12 can be selected as G1 / 2 external thread valve seat, welded to the top of the upper cylinder 1, and the automatic exhaust valve 13, model can be selected as P11X-16P-DN15, is threaded to the exhaust valve seat 12.

[0033] Liquid enters the lower cylinder 4 through inlet 3, entering from the side. The liquid flows downwards first, and during high-speed rotation, it has a certain centrifugal force. Using centrifugal force and gravity, impurities are initially separated from the liquid (first-stage filtration). The separated impurities settle to the bottom of the lower cylinder 4 and are discharged through the drain hole 8. Large impurities can be manually removed through the observation hole 7. The liquid after initial filtration flows upwards along the inner cylinder 6 and enters the upper cylinder 1. It undergoes secondary filtration through the filter screen 11 to remove fine impurities and is finally discharged from the outlet 5 into the system pipeline.

[0034] The outlet 5 of the upper cylinder 1 can be rotated and adjusted in multiple directions to adapt to different on-site installation layouts. According to the system pipeline layout, the upper cylinder 1 can be rotated to adjust to the appropriate installation direction. The inlet 3 is welded to the system inlet pipe and the outlet 5 is welded to the system outlet pipe using the "flat inlet and flat outlet" method. The drain pipe is connected to the drain hole flange 8 for periodic slag removal.

[0035] After the liquid enters the device, it undergoes a first-stage cyclone separation and a second-stage filtration through a filter screen. Impurities are periodically discharged through the drain port flange 8. The accumulation of internal impurities can be observed through the observation port 7, and large impurities can be removed directly through the observation port. The entire operation process requires no downtime maintenance; only the filter screen condition needs to be checked every 12-18 months.

[0036] This invention provides a low-resistance multi-directional cyclone filtration device, which has the advantages of low resistance, low energy consumption, long service life, low cost, flexible installation, and high filtration accuracy. Compared with the Y-type filter used in conventional pump stations, this invention is significantly optimized.

[0037] Compared with the prior art, the present invention has the following significant advantages: High-precision filtration: Two-stage filtration (cyclone separation + 40-mesh filter) ensures stable filtration accuracy and effectively removes impurities with a particle size ≥100μm, protecting downstream equipment for safe operation.

[0038] Long lifespan: Large particles are separated in advance through the first stage of cyclone filtration, preventing them from impacting the filter screen. Combined with the low flow rate design, the filter screen lifespan is extended to 2-3 years, which is 4-6 times longer than that of traditional Y-type filters.

[0039] Low resistance and low energy consumption: The device's cavity volume is 6 times larger than that of a traditional Y-type filter, reducing water flow velocity by more than 82% and resistance loss by more than 90%. Low-head water pumps can be selected, reducing operating energy consumption by 15%-20%.

[0040] Low cost: Only one unit needs to be installed in the main system pipe to meet the needs (no need to equip each water pump separately), reducing equipment procurement costs by about 20%; and no downtime maintenance is required, extending the maintenance cycle to 12-18 months, reducing maintenance costs by 70%.
