Description

Technical Field

[0001] The utility model relates to the technical field of filter element membrane filaments, and particularly relates to a novel filter element membrane filament structure. Background Technique

[0002] During the use of current vertical ultrafiltration filter elements, since the water inlet and outlet are at the bottommost end, based on the natural characteristics of gas rising and water flowing downward, the gas brought in by filter element cleaning, replacement and water source is likely to accumulate in the upper part of the filter element. After the PVDF membrane filaments pass water, the air exhaust performance is poor, and the gas inside the filter element cannot be effectively discharged, resulting in situations such as low purification efficiency, large pressure loss, and unstable water outlet of the filter element, and there is also a relatively large risk of water leakage.

[0003] For example, the patent application with the application number CN202120830441.X includes an external shell and a filter membrane group installed inside the external shell. The special feature is that the filter membrane group includes a membrane filament cylinder. The external pressure membrane filaments and the exhaust membrane filaments are both bent into a U shape and then the ends are inserted into the membrane filament cylinder; the external pressure membrane filaments are wrapped outside the exhaust membrane filaments, and the height of the external pressure membrane filaments is lower than that of the exhaust membrane filaments; the exhaust membrane filaments are high-permeability polyethylene ultrafiltration membrane filaments, and the external pressure membrane filaments are hydrophilic polyvinylidene fluoride membranes.

[0004] Common external pressure membrane filaments and exhaust membrane filaments are both bent into a U shape and then the ends are inserted into the membrane filament cylinder, and the external pressure membrane filaments are wrapped outside the exhaust membrane filaments.

[0005] However, when common external pressure membrane filaments and exhaust membrane filaments are in use, the external pressure membrane filaments and the exhaust membrane filaments are repeatedly washed by water flow, and the external pressure membrane filaments and the exhaust membrane filaments cannot freely swing in the water. The impact force received by a single external pressure membrane filament and exhaust membrane filament is relatively large, resulting in the external pressure membrane filaments and the exhaust membrane filaments being washed off by the water flow, thereby reducing the filtering effect of the filter element membrane filaments. There is an urgent need to design a novel filter element membrane filament structure to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a novel filter element membrane filament structure to solve the above deficiencies in the prior art.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] It includes a filter element frame, a water outlet pipe and a membrane filament assembly, and the membrane filament assembly is arranged at the bottom of the filter element frame;

[0009] The membrane filament assembly includes a first exhaust limiting ring fixedly installed at the bottom of the filter element frame. A number of exhaust membrane filaments are arranged inside the first exhaust limiting ring. A second exhaust limiting ring is sleeved on the outer surface of one end of the exhaust membrane filaments. A first external pressure limiting ring is fixedly installed at the bottom of the filter element frame. A number of external pressure membrane filaments are arranged inside the first external pressure limiting ring. A second external pressure limiting ring is sleeved on the outer surface of one end of the external pressure membrane filaments.

[0010] When the membrane filament assembly is repeatedly washed by water flow, the external pressure membrane filaments and the exhaust membrane filaments can swing freely in the water, thereby reducing the impact force on a single external pressure membrane filament and exhaust membrane filament, increasing the service life of a single external pressure membrane filament and exhaust membrane filament, and improving the filtering effect of the filter element membrane filament structure.

[0011] A connecting plate is fixedly installed at the bottom of the second exhaust limiting ring. The connecting plate is fixedly connected to the second external pressure limiting ring.

[0012] The exhaust membrane filaments are dispersedly arranged, and the external pressure membrane filaments are dispersedly arranged.

[0013] A water outlet groove is formed at the top of the filter element frame. The water outlet pipe is fixedly installed in the water outlet groove and corresponds to the first exhaust limiting ring.

[0014] The exhaust membrane filaments are high-permeability polyethylene ultrafiltration membrane filaments, and the external pressure membrane filaments are hydrophilic polyvinylidene fluoride membranes.

[0015] The external pressure membrane filaments are annularly wrapped around the outer surface of the exhaust membrane filaments.

[0016] In the above technical solution, a novel filter element membrane filament structure provided by the present utility model has the following beneficial effects:

[0017] 1. When the membrane filament assembly is repeatedly washed by water flow, the external pressure membrane filaments and the exhaust membrane filaments can swing freely in the water, thereby reducing the impact force on a single external pressure membrane filament and exhaust membrane filament, increasing the service life of a single external pressure membrane filament and exhaust membrane filament, and improving the filtering effect of the filter element membrane filament structure.

[0018] 2. The connecting plate can limit and fix the second exhaust limiting ring and the second external pressure limiting ring, thereby increasing the stability of the external pressure membrane filaments and the exhaust membrane filaments during use.

[0019] 3. The dispersedly arranged external pressure membrane filaments and exhaust membrane filaments can swing freely in the water while discharging the residual gas or the gas brought in by the water source in the filter element membrane filament structure, thereby preventing the situation that a single external pressure membrane filament and exhaust membrane filament are washed and broken by the water flow.

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0027] As Figures 1-4 shown, a novel filter element membrane filament structure provided by an embodiment of the present utility model.

[0028] It includes a filter element frame 1, a water outlet pipe 2 and a membrane filament assembly 3. The membrane filament assembly 3 is arranged at the bottom of the filter element frame 1;

[0029] The membrane filament assembly 3 includes a first exhaust limiting ring 4 fixedly installed at the bottom of the filter element frame 1. A number of exhaust membrane filaments 5 are arranged inside the first exhaust limiting ring 4. A second exhaust limiting ring 6 is sleeved on the outer surface of one end of the exhaust membrane filament 5. A first external pressure limiting ring 7 is fixedly installed at the bottom of the filter element frame 1. A number of external pressure membrane filaments 8 are arranged inside the first external pressure limiting ring 7. A second external pressure limiting ring 9 is sleeved on the outer surface of one end of the external pressure membrane filament 8. The water flow flushes the external pressure membrane filaments 8, and a single external pressure membrane filament 8 is driven by the water flow to swing. The external pressure membrane filament 8 performs the first filtration on the water flow. The water flow flows to the exhaust membrane filaments 5 through the external pressure membrane filaments 8. A single exhaust membrane filament 5 is driven by the water flow to swing. The exhaust membrane filament 5 performs the second filtration on the water flow. The filtered water flow flows to the first exhaust limiting ring 4 through the exhaust membrane filaments 5. The filtered water flow flows out from the water outlet pipe 2 through the first exhaust limiting ring 4.

[0030] When the membrane filament assembly 3 is repeatedly flushed by the water flow, the external pressure membrane filaments 8 and the exhaust membrane filaments 5 can freely swing in the water, thereby reducing the impact force on a single external pressure membrane filament 8 and an exhaust membrane filament 5, increasing the service life of a single external pressure membrane filament 8 and an exhaust membrane filament 5, and improving the filtration effect of the filter element membrane filament structure.

[0031] Refer to Figure 2 , a connecting plate 10 is fixedly installed at the bottom of the second exhaust limiting ring 6 of this embodiment, and the connecting plate 10 is fixedly connected to the second external pressure limiting ring 9.

[0032] The connecting plate 10 can limit and fix the second exhaust limiting ring 6 and the second external pressure limiting ring 9, thereby increasing the stability of the external pressure membrane filaments 8 and the exhaust membrane filaments 5 during use.

[0033] The exhaust membrane filaments 5 are dispersedly arranged, and the external pressure membrane filaments 8 are dispersedly arranged.

[0034] The dispersedly arranged external pressure membrane filaments 8 and exhaust membrane filaments 5 can freely swing in the water while discharging the residual gas or the gas brought in by the water source in the filter element membrane filament structure, thereby preventing the situation that a single external pressure membrane filament 8 and an exhaust membrane filament 5 are washed and broken by the water flow.

[0035] A water outlet groove 11 is opened at the top of the filter element frame 1. The water outlet pipe 2 is fixedly installed in the water outlet groove 11, and the water outlet pipe 2 corresponds to the first exhaust limiting ring 4.

[0036] The water outlet pipe 2 can guide the water flow, so that the water flow flows out of the filter element membrane filament structure through the external pressure membrane filaments 8 from the exhaust membrane filaments 5.

[0037] The exhaust membrane filaments 5 are high-permeability polyethylene ultrafiltration membrane filaments, and the external pressure membrane filaments 8 are hydrophilic polyvinylidene fluoride membranes.

[0038] The external pressure membrane filament 8 can effectively remove impurities such as microorganisms, organic matters, and particulate matters in water, thereby enhancing the filtering effect of the filter element membrane filament structure.

[0039] The exhaust membrane filament 5 can intercept impurities, remove heavy metals, eliminate odors, retain beneficial minerals, and extend the service life of the water purifier, thereby improving the filtering effect of the filter element membrane filament structure.

[0040] The external pressure membrane filament 8 is annularly wrapped around the outer surface of the exhaust membrane filament 5.

[0041] The external pressure membrane filament 8 can achieve better filtering effect while protecting the exhaust membrane filament 5 by wrapping.

[0042] Working principle: First, the water flow flushes the external pressure membrane filament 8. Each single external pressure membrane filament 8 is driven by the water flow to swing. The external pressure membrane filament 8 conducts the first filtration on the water flow. The water flow flows through the external pressure membrane filament 8 towards the exhaust membrane filament 5. Each single exhaust membrane filament 5 is driven by the water flow to swing. The exhaust membrane filament 5 conducts the second filtration on the water flow. The filtered water flow flows through the exhaust membrane filament 5 towards the first exhaust limit ring 4. The filtered water flow flows out from the water outlet pipe 2 through the first exhaust limit ring 4.

[0043] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
