Furthermore, features defined with "first," "second," or "third" may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "several" means two or more.

[0038] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0039] The following is for reference. Figures 1 to 6 A filtration device according to an embodiment of the present invention is described.

[0040] refer to Figure 1 and Figure 2 As shown, a filtration device according to an embodiment of the present utility model includes a vessel body 100, an anti-clogging component 200, a first baffle assembly 300, and a second baffle assembly 400.

[0041] A water inlet pipe 110 is provided on the side of the vessel body 100. A first water outlet pipe 120 and a second water outlet pipe 130 are provided at the bottom of the vessel body 100 to communicate with the outside. An anti-clogging component 200 is installed on the first water outlet pipe 120. A first baffle assembly 300 is provided inside the vessel body 100 and forms a first cavity 140 with the inner side of the vessel body 100. A second baffle assembly 400 is provided inside the vessel body 100 and forms a second cavity 150 with the vessel body 100, the anti-clogging component 200 and the first baffle assembly 300. A filter material 500 is provided inside the second cavity 150. The height of the filter material 500 stacked is higher than the height of the second baffle assembly 400. A third cavity 410 is formed inside the second baffle assembly 400. The third cavity 410 is unidirectionally connected to the second water outlet pipe 130. The water inlet pipe 110, the first cavity 140, the second cavity 150, the third cavity 410 and the first water outlet pipe 120 are connected.

[0042] When the device performs filtration, the first outlet pipe 120 is sealed, and the second outlet pipe 130 is opened. The water to be treated enters the first cavity 140 formed between the vessel body 100 and the first baffle assembly 300 through the inlet pipe 110, and then enters the second cavity 150 through the first baffle assembly 300. After being filtered by the filter material 500 in the second cavity 150, the water enters the third cavity 410 and flows out from the second outlet pipe 130, thus achieving water filtration. The first baffle assembly 300 and the second baffle assembly 400 ensure that the filter material 500 remains in the second cavity 150 and is not discharged with the water to be treated into the third cavity 150, nor does it flow back and block the inlet pipe 110.

[0043] When treating the precipitated impurities in the device, the second outlet pipe 130 and the first outlet pipe 120 are first sealed. Clean cleaning liquid is then introduced from the inlet pipe 110 into the first cavity 140 formed between the vessel body 100 and the first baffle assembly 300, and passes through the first baffle assembly 300 into the second cavity 150 to wet and rinse the filter material 500, allowing the impurities to settle and accumulate at the bottom of the vessel body. Then, the first outlet pipe 120 is opened, allowing the impurities to be discharged through the anti-clogging component 200. The anti-clogging component 200 prevents the filter material 500 from being discharged from the vessel body 100 through the first outlet pipe 120. It is understood that the cleaning liquid is generally pure water, and common precipitated impurities include sand, calcium carbonate, barium sulfate, and other crystalline and amorphous precipitates.

[0044] Understandably, when the device is treating water, the second outlet pipe 130 can be closed simultaneously first, and then the second outlet pipe 130 can be opened after a certain amount of water has been stored in the vessel 100, so that a certain water pressure can be formed in the vessel 100 first, thereby enhancing the filtration efficiency.

[0045] Understandably, the filter media 500 is selected based on the requirements for water filtration, and common types include cation exchange resin, nitrifying bacteria cotton balls, and nitrate removal resin, etc.

[0046] Understandably, during filtration, when the water to be treated comes into contact with the second baffle assembly 400, a pressure difference is created because the third cavity 410 inside the second baffle assembly 400 is connected to the outside. This causes the filter material 500 to adhere tightly to the outside of the second baffle assembly 400, and the water to be treated will have to pass through the filter material 500 to enter the third cavity 410 and then be discharged. Therefore, the filtered water obtained at the beginning of the device's operation is generally not filtered enough and needs to be used after the device has been running for a period of time.

[0047] In some specific embodiments of this utility model, an extrusion assembly 600 is also included. The extrusion assembly 600 includes a driving member 610 and a pressure plate 620 disposed at the output end of the driving member 610. The driving member 610 is installed on the top of the vessel body 100, and the output end of the driving member 610 is located inside the vessel body 100. The output end of the driving member 610 is adapted to drive the pressure plate 620 to move in the up and down direction. The periphery of the pressure plate 620 is adapted to the inner side of the first baffle assembly 300.

[0048] refer to Figure 2 As shown, in this embodiment, the driving component 610 is a telescopic cylinder, which can drive the pressure plate 620 to move up and down inside the first baffle assembly 300. During the operation of the equipment, it can squeeze the water surface and increase the pressure, thereby accelerating the filtration or cleaning efficiency of the device.

[0049] Understandably, during the operation of the device, when the extrusion component 600 is not running, the water inlet of the inlet pipe 110 is greater than that of the first outlet pipe 120 and the second outlet pipe 130, causing the water level in the vessel 100 to gradually rise. When the water level rises and approaches the extrusion component 600, the extrusion component 600 starts to operate, and the pressure plate 620 descends to extrude, which increases the pressure in the vessel 100 and increases the water output efficiency of the first outlet pipe 120 and the second outlet pipe 130, thereby increasing the filtration effect and the efficiency of cleaning filtered impurities.

[0050] In some specific embodiments of this utility model, the first baffle assembly 300 is provided with a plurality of first filter holes 310, the second baffle assembly 400 is provided with a plurality of second filter holes 420, and the anti-clogging component 200 is provided with a plurality of third filter holes 210. The areas of the plurality of first filter holes 310, the plurality of second filter holes 420 and the plurality of third filter holes 210 are all smaller than the maximum cross-section of the filter material 500.

[0051] refer to Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the arrangement of a plurality of first filter holes 310, a plurality of second filter holes 420 and a plurality of third filter holes 210 enables the filter material 500 to remain in the second cavity 150 to act as a barrier when the liquid flows between the first cavity 140, the second cavity 150 and the third cavity 410.

[0052] In some specific embodiments of this utility model, the inside of the vessel body 100 is provided with an annular first protrusion structure 160 facing the inside of the vessel body 100, the upper end of the first baffle assembly 300 is provided with an annular second protrusion structure 320 facing the outside of the vessel body 100, the lower end of the first baffle assembly 300 is in contact with the bottom of the vessel body 100, and the second protrusion structure 320 is movably connected to the upper end face of the first protrusion structure 160.

[0053] refer to Figure 1 and Figure 6 As shown, in this embodiment, the first baffle assembly 300 can be mounted on the first protrusion structure 160 of the vessel body 100 via the second protrusion structure 320, making the installation of the vessel body 100 and the first baffle assembly 300 more convenient.

[0054] In some specific embodiments of this utility model, the second baffle assembly 400 includes a baffle member 430, a first one-way valve 440 and a connector 450 connected sequentially from top to bottom. The connector 450 is disposed on the second water outlet pipe 130. The second water outlet pipe 130 passes through the connector 450 and is connected to the first one-way valve 440. The valve opening direction of the first one-way valve 440 faces the second water outlet pipe 130. The baffle member 430 is provided with a plurality of second filter holes 420. A third cavity 410 is formed inside the baffle member 430.

[0055] refer to Figure 2 and Figure 4 As shown, in this embodiment, the baffle 430 has a ring structure, which can better withstand water pressure for filtration. The first one-way valve 440 can prevent water from flowing back into the third cavity 410. The connector 450 is easy to install onto the second outlet pipe 130.

[0056] In some specific embodiments of this utility model, the second baffle assembly 400 further includes at least three backflushing members 460 with identical structures. The backflushing members 460 are mounted on the connector 450, and the second water outlet pipe 130 is in one-way communication with the backflushing members 460. The backflushing member 460 includes an exhaust structure 461. One end of the exhaust structure 461 is provided with a plurality of air outlets 4611, and the other end of the exhaust structure 461 is provided with a second one-way valve 462. The opening direction of the second one-way valve 462 is towards the plurality of air outlets 4611, and the area of ​​each of the plurality of air outlets 4611 is smaller than the maximum cross-section of the filter material 500.

[0057] refer to Figure 2 and Figure 4 As shown, in this embodiment, six backflushing elements 460 are evenly arranged in a ring around the connector 450, and the second water outlet pipe 130 is unidirectionally connected to the six backflushing elements 460. The setting of the second one-way valve 462 ensures that water flow will not enter the second water outlet pipe 130 through the several air outlets 4611. The area of ​​each of the several air outlets 4611 is smaller than the maximum cross-section of the filter material 500, which also prevents the filter material 500 from entering the second water outlet pipe 130 through the exhaust structure 461, and increases the pressure of the discharged gas, making the cleaning degree of the filter material 500 stronger. When the device cleans impurities, gas can be injected from the second water outlet pipe 130, allowing the filter material 500 to tumble in the cleaning liquid, so that impurities can be better removed from the filter material 500. It is understood that the number of backflushing elements 460 can also be four, eight, or ten, etc. It is understood that the number of several air outlets 4611 can be set as many as possible while ensuring structural strength.

[0058] In some specific embodiments of this utility model, the first water outlet pipe 120 is provided with a first water outlet 121 and a first air inlet 122, and the first water outlet 121 and the first air inlet 122 are located below the anti-blocking component 200.

[0059] refer to Figure 2 As shown, in this embodiment, the first outlet 121 facilitates the discharge of wastewater containing impurities, and the first air inlet 122 allows gas to enter the vessel 100, causing the water flow at the anti-clogging component 200 to agitate and the filter material 500 to roll, thereby assisting the filter impurities to leave the filter material 500 for sedimentation and enhancing the impurity cleaning ability.

[0060] Understandably, the air pressure at the first air inlet 122 must be greater than the maximum water pressure at the first water outlet 121 to allow air to be injected and prevent water from flowing back into the first air inlet 122. Understandably, the best effect is achieved when air blowing is performed only when the filter material 500 has a density greater than that of the cleaning liquid or when the water level drops to the point where the filter material 500 is close to the anti-clogging component 200.

[0061] In some specific embodiments of this utility model, the second water outlet pipe 130 passes through the first water outlet pipe 120 and the anti-blocking component 200, and the second water outlet pipe 130 is provided with a second water outlet 131 and a second air inlet 132.

[0062] refer to Figure 2As shown, in this embodiment, the second outlet 131 facilitates the discharge of filtered water, and the second air inlet 132 allows gas to enter the vessel 100 through the backflushing member 460, causing the water flow at the backflushing member 460 to agitate and the filter material 500 to roll, thereby assisting the removal of impurities from the filter material 500 for sedimentation and enhancing the impurity removal capability.

[0063] Understandably, the air pressure at the second air inlet 132 must be greater than the maximum water pressure at the second water outlet 131 in order to inject air. Understandably, the best effect is achieved when air blowing is performed only when the density of the filter material 500 is greater than that of the cleaning liquid or when the water level drops to the point where the filter material 500 is close to the anti-clogging component 200.

[0064] In some specific embodiments of this utility model, several supports 700 are also provided on the outer side of the vessel body 100.

[0065] refer to Figure 1 As shown in this embodiment, four supports 700 are provided on the outside of the vessel body 100 to facilitate the placement and installation of the entire device. It can be understood that the number of supports 700 is set according to the size of the vessel body 100 and the weight it bears. The larger the vessel body 100 or the heavier the load, the more supports 700 are needed. There can also be three, five or six supports.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
