Description

Technical Field

[0001] The present application relates to the technical field of filtering equipment, and in particular to a floor-standing filter. Background Art

[0002] Floor filters are a type of filtration equipment designed for ground installation, usually with a large filtration area and capacity, suitable for industrial or commercial environments that need to handle large volumes of fluid. The name of the floor filter comes from its installation method, which is to place it directly on the ground, rather than hanging or mounting it on other structures.

[0003] Existing floor-standing filters usually include a tank body, a partition, multiple filter cartridges, an inlet pipe and an outlet pipe. The tank body has a cavity inside, and the partition divides the cavity into two spaces, the inlet pipe and the outlet pipe are connected to the tank body and communicate with the space above and below the partition respectively; multiple filter cartridges are installed on the partition and located in the space below the partition. After the liquid to be filtered enters the space above the partition in the cavity through the inlet pipe, it will enter the multiple filter cartridges and be filtered by the filter cartridges. The filtered liquid then flows out of the space below the partition in the cavity of the filter cartridge and is finally discharged through the outlet pipe.

[0004] However, due to its large size, the filter cartridges inside the floor-standing filter are usually not frequently cleared. If some filter cartridges are blocked, the other filter cartridges can still filter the liquid, but the filtering efficiency of the floor-standing filter will be significantly affected.

[0005] Therefore, there is an urgent need for a floor-standing filter that can maintain a high filtration efficiency for a long time. Summary of the invention

[0006] The present application provides a floor-standing filter, which can effectively reduce the probability of impurity blockage inside the filter, thereby enabling the filter to effectively maintain a high filtering efficiency for a long time.

[0007] The present application provides a floor-standing filter, which adopts the following technical solution: A floor-standing filter comprises a tank body, a partition, a water inlet pipe, a water outlet pipe and a plurality of filter cartridges, wherein the tank body has a cavity inside, the partition is arranged inside the tank body and divides the cavity into a first space and a second space distributed up and down, the plurality of filter cartridges are arranged on the partition and located in the second space, and further comprises a plurality of first blades; The partition is rotatably connected to the tank body, and the rotation axis of the partition coincides with its own axis and the axis of the tank body; a plurality of filter cartridges are distributed on the partition in a circular array with the axis of the partition as the axis, and a plurality of water inlets are correspondingly opened on the partition so that the first space is communicated with the interior of the corresponding filter cartridge, and the interior of the filter cartridge is communicated with the second space through the mesh holes on the surface of the filter cartridge; Multiple first blades are arranged on the partition and located in the first space, one ends of the multiple first blades are connected to each other at the center position of the partition, and the multiple first blades are distributed in a circular array on the partition with the axis of the partition as the axis; the water inlet direction of the water inlet pipe is eccentric with respect to the axis of the tank body, so that the force exerted by the liquid entering the first space on the first blades can drive the partition to rotate.

[0008] By adopting the above technical solution, after the liquid to be filtered enters the first space through the water inlet pipe, the force of the liquid flow on the first blade can drive the partition to rotate relative to the tank body, so that the multiple filter cartridges move in a circle in the second cavity, which can effectively reduce the probability of impurities clogging the mesh holes on the surface of the filter cartridge. At the same time, the impurities clogging the filter cartridge can be dropped with the help of the surging of the liquid in the second cavity, so that it can effectively maintain a high filtration efficiency for a long time.

[0009] Optionally, the number of the first blades arranged on the partition is equal to the number of the water inlets opened, and there is one water inlet between each adjacent first blade.

[0010] By adopting the above technical solution, the influence of the first blade on the liquid passing through the water inlet can be reduced, thereby reducing the influence on the efficiency of the liquid flow being filtered by the filter cartridge.

[0011] Optionally, the first blade is arc-shaped, and one side of the first blade has a guide surface for liquid flow to exert force on it, and the guide surface can guide the liquid exerting force on it to flow toward the adjacent water inlet.

[0012] By adopting the above technical solution, the first blade can not only drive the partition to rotate under the force of liquid flow, but also guide the liquid to flow in the direction close to the adjacent water inlet, thereby further reducing the influence of the first blade on the liquid passing through the water inlet.

[0013] Optionally, the filter cartridge includes a first cartridge and a second cartridge, the second cartridge is sleeved with the first cartridge, the first cartridge has a first filter space inside, and a second filter space is formed between the second cartridge and the first cartridge; A plurality of first filter holes are evenly distributed on the surface of the first cylinder, and a plurality of second filter holes are evenly distributed on the surface of the second cylinder; the first filter space is connected to the second filter space through the first filter holes, and the second filter space is connected to the second space through the second filter holes.

[0014] By adopting the above technical solution, the filter cartridge can perform double filtration on the liquid to be filtered, thereby further improving the filtering effect of the filter on the liquid.

[0015] Optionally, the aperture of the first filter hole is larger than the aperture of the second filter hole.

[0016] By adopting the above technical solution, the filtering effect of the filter cartridge on the liquid can be strengthened layer by layer, further improving the filtering effect of the filter on the liquid; at the same time, layered filtration can further reduce the probability of the filter cartridge being blocked by impurities.

[0017] Optionally, the apertures of the plurality of second filter holes are different, and the aperture of the second filter hole close to the water-facing side of the second cylinder is larger than the aperture of the second filter hole close to the water-receiving side of the second cylinder.

[0018] By adopting the above technical solution, the filter cartridge can further filter the liquid through the second filter hole on the back water side during the circular motion in the second space, thereby further improving the filtering effect on the liquid; at the same time, the liquid in the second space can penetrate into the interior of the filter cartridge during this process, thereby clearing the second filter hole and the first filter hole, thereby further reducing the probability of the filter cartridge being blocked by impurities.

[0019] Optionally, the second cylinder has a sedimentation groove at one end away from the partition, and the sedimentation groove is communicated with the second filtering space.

[0020] By adopting the above technical solution, impurities separated by filtration in the liquid in the filter cartridge can be conveniently concentrated and accumulated in the sedimentation tank, thereby reducing the probability of impurities clogging the filter cartridge and reducing the probability of filtered impurities being discharged with the liquid through the outlet pipe.

[0021] Optionally, it also includes a rotating shaft and a plurality of second blades; The rotating shaft is arranged on the partition and is located in the second space, and the rotating axis of the rotating shaft coincides with the axis of the rotating shaft and the axis of the partition; The plurality of second blades are all arranged at one end of the rotating shaft away from the partition, and the plurality of second blades are distributed in a circular array with the axis of the rotating shaft as the axis; When the liquid in the second space flows into the water outlet pipe, the force exerted by the liquid flow on the second blade can drive the rotating shaft to rotate.

[0022] By adopting the above technical solution, the circular motion of multiple second blades in the second space can further drive the liquid in the second space to surge, thereby further driving the liquid in the second space into the interior of the filter cartridge to achieve a clearing effect, thereby further reducing the probability of the filter cartridge being affected by impurities.

[0023] Optionally, the direction in which the liquid enters the water outlet pipe is eccentric relative to the axis of the rotating shaft.

[0024] By adopting the above technical solution, the liquid flowing into the water outlet pipe in the second space can drive the plurality of second blades to move in a circular motion, thereby further improving the effect of the plurality of second blades stirring the liquid by the circular motion trend.

[0025] Optionally, the direction in which the liquid flow drives the partition to rotate is opposite to the direction in which the liquid flow drives the rotating shaft to rotate.

[0026] By adopting the above technical solution, the intensity of the liquid surging in the second space can be further enhanced, thereby further improving the clearing effect of the liquid flow in the second space on the filter cartridge.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a floor-standing filter, which is fixedly installed on the ground and is used to filter a large amount of liquid.

[0032] Reference Figure 1 and Figure 2 The floor-standing filter comprises a tank body 1, a partition 2, a plurality of filter cartridges 3, a water inlet pipe 4 and a water outlet pipe 5.

In this embodiment, preferably, a total of five water inlets 21 are provided on the partition 2.

[0035] Reference Figure 2 and Figure 3 The filter cartridge 3 is a cylindrical structure as a whole, installed on the partition 2 and located in the second space 112, and the plurality of filter cartridges 3 correspond one by one to the plurality of water inlets 21 provided on the partition 2. In this embodiment, the floor-standing filter preferably includes five filter cartridges 3 in total.

[0036] Reference Figure 2 and Figure 4 The filter cartridge 3 includes a first cartridge body 31 and a second cartridge body 32 , and both the first cartridge body 31 and the second cartridge body 32 are hollow cylindrical structures.

[0037] The first cylinder 31 has a first filter space 311 inside, and the first filter space 311 is formed with an opening along the axial direction of the first cylinder 31 and penetrates one end of the first cylinder 31, and after the first cylinder 31 is installed on the partition 2, the first filter space 311 can communicate with the corresponding water inlet 21 through its own opening, so that the first filter space 311 is communicated with the first space 111; the surface of the first cylinder 31 is evenly distributed with a plurality of first filter holes 312 for communicating the first filter space 311 with the outer space of the first cylinder 31, and the plurality of first filter holes 312 are respectively distributed on the circumferential side of the first cylinder 31 in the radial direction and the end of the first cylinder 31 away from the opening of the first filter space 311. In this embodiment, it is preferred that the first filter hole 312 is a circular hole, and the aperture sizes of the plurality of first filter holes 312 are equal.

[0038] The second cylinder 32 has a second filter space 321 inside, and the second filter space 321 is formed with an opening along the axis direction of the second cylinder 32 and through one end of the second cylinder 32, and after the second cylinder 32 is installed on the partition 2, the opening of the second filter space 321 is upward and the second cylinder 32 will be sleeved with the first cylinder 31, at this time, the first cylinder 31 is located in the second filter space 321 and the first filter space 311 can communicate with the corresponding second filter space 321 through a plurality of first filter holes 312, and at this time, the axis of the first cylinder 31 coincides with the axis of the corresponding second cylinder 32, and the first cylinder 31 is spaced from the inner wall of the corresponding second filter space 321. The surface of the second cylinder 32 is evenly distributed with a plurality of second filter holes 322 for communicating the second filter space 321 with the second space 112, and the plurality of second filter holes 322 are only distributed on the circumferential side of the second cylinder 32 in the radial direction. In this embodiment, the second filter hole 322 is preferably also a circular hole, and the aperture size of the second filter hole 322 is smaller than the aperture size of the first filter hole 312 .

[0039] A sedimentation trough 323 is provided inside the second cylinder 32 at the end of the second filter space 321 away from the opening thereof for collecting impurities separated by filtration in the liquid. The multiple second filter holes 322 on the second cylinder 32 are all located above the sedimentation trough 323. Impurities in the second filter space 321 can move downward into the sedimentation trough 323 under the action of their own gravity.

[0040] Reference Figure 2 and Figure 3 , a plurality of first blades 6 are also fixedly mounted on the partition 2, and the plurality of first blades 6 are all located in the first space 111; the first blade 6 is an arc-shaped sheet structure as a whole, the arc-shaped trajectory direction of the first blade 6 is perpendicular to the axis of the partition 2, and the plurality of first blades 6 are distributed in a circular array on the partition 2 with the axis of the partition 2 as the axis; the plurality of first blades 6 are fixedly connected to each other along their own arc-shaped trajectory at one end close to the axis of the partition 2, and there is a gap between the end of the first blade 6 along its own arc-shaped trajectory away from the axis of the partition 2 and the inner wall of the first space 111. In this embodiment, it is preferred that the number of the plurality of first blades 6 mounted on the partition 2 is equal to the number of the plurality of water inlets 21 opened on the partition 2, and a water inlet 21 is opened on the partition 2 at the position between adjacent first blades 6.

[0041] The water outlet end of the water inlet pipe 4 is fixedly connected to the top of the tank body 1 and communicates with the first space 111 . The water outlet direction of the water inlet pipe 4 is horizontally aligned with the multiple first blades 6 , and the water outlet direction of the water inlet pipe 4 is eccentric relative to the axis of the tank body 1 .

[0042] One side of the first blade 6 has a guide surface 61 for contacting the liquid flowing into the first space 111 through the water inlet pipe 4, and the guide surface 61 is an arc-shaped surface; after the liquid enters the first space 111 through the water inlet pipe 4, the liquid can actively contact the guide surface 61 on the first blade 6. At this time, the force exerted by the liquid on the guide surface 61 can drive the partition 2 to rotate relative to the tank body 1, so that the liquid that continuously enters the first space 111 through the water inlet pipe 4 can contact the guide surfaces 61 on multiple first blades 6 in turn, thereby circulating; at the same time, in the process of the liquid exerting a force on the guide surface 61, the guide surface 61 can guide the liquid, guiding the liquid to flow along the guide surface 61 in the direction close to the adjacent water inlet 21, so as to facilitate the liquid to enter the filter cartridge 3 through the water inlet 21 for filtration.

[0043] When the first filter hole 312 or the second filter hole 322 is blocked by impurities during the process of filtering liquid by the filter cartridge 3, the filter cartridge 3 can promote the liquid in the second space 112 to enter the second filter space 321 through the second filter hole 322 or promote the liquid in the second filter space 321 to enter the first filter space 311 through the first filter hole 312 during the process of rotating around the axis of the partition 2 along with the partition 2 in the second space 112. At this time, the impurities that cause blockage in the first filter hole 312 or the second filter hole 322 can leave the corresponding first filter hole 312 or the second filter hole 322 under the action of the liquid, so as to achieve the effect of clearing the blockage.

[0044] Furthermore, it is preferred that the aperture sizes of the plurality of second filter holes 322 on the second cylinder 32 are different.

[0045] During the circular motion of the filter cylinder 3 as the partition plate 2 rotates, the position on the second cylinder 32 that actively contacts the liquid is the upstream side, and the other positions are the downstream side. The aperture size of the second filter hole 322 on the second cylinder 32 near the upstream side is larger than the aperture size of the second filter hole 322 on the second cylinder 32 near the downstream side, and the aperture size of the second filter hole 322 on the second cylinder 32 gradually decreases from the upstream side to the downstream side.

[0046] At this time, the liquid flowing from the first space 111 into the second space 112 can be filtered to the minimum extent by the filter cartridge 3 (enough to meet the required filtering requirements), and when the multiple filter cartridges 3 rotate and make circular motion with the partition 2, the filter cartridge 3 can also filter the liquid in the second space 112 to a higher extent, further improving the filtering effect on the liquid.

[0047] Reference Figure 2 and Figure 4 A rotating shaft 7 and a plurality of second blades 8 are also mounted on the partition 2 , and the rotating shaft 7 and the plurality of second blades 8 are both located in the second space 112 .

[0048] The rotating shaft 7 is an overall cylindrical structure and is rotatably connected to the partition 2. The rotating axis 7 line of the rotating shaft 7 coincides with its own axis and the axis of the partition 2. At this time, the rotating shaft 7 is surrounded by multiple filter cartridges 3; multiple second blades 8 are installed at the end of the rotating shaft 7 away from the partition 2. The second blades 8 are an overall rectangular sheet structure. The multiple second blades 8 are distributed in a circular array on the rotating shaft 7 with the axis of the rotating shaft 7 as the axis, and the length direction of the second blades 8 is the same as the radial direction relative to the rotating shaft 7; in the process of the multiple second blades 8 rotating with the rotating shaft 7 and making circular motion along the axis of the rotating shaft 7, a certain distance is maintained between the end of the second blade 8 away from the rotating shaft 7 and the adjacent filter cartridge 3.

[0049] The water inlet end of the water outlet pipe 5 is fixedly connected to the bottom of the tank body 1 and communicates with the second space 112. The water inlet direction of the water outlet pipe 5 is aligned with the multiple second blades 8 in the horizontal direction. The water inlet direction of the water outlet pipe 5 is also eccentric relative to the axis of the tank body 1, and the water outlet direction of the water inlet pipe 4 is opposite to the eccentric direction of the water inlet direction of the water outlet pipe 5 relative to the axis of the tank body 1.

[0050] Reference Figure 3 and Figure 4 In the process of the filtered liquid in the second space 112 being discharged through the outlet pipe 5, the liquid in the second space 112 can exert force on the multiple second blades 8 in sequence during the process of flowing into the outlet pipe 5, so that the multiple second blades 8 rotate relative to the partition 2 through the rotating shaft 7 and perform circular motion, and the direction of the circular motion of the multiple second blades 8 is opposite to the direction of the circular motion of the multiple first blades 6.

[0051] At this time, the multiple filter cartridges 3 rotate with the partition 2 and make circular motion to stir the liquid in the second space 112 in a direction opposite to the stirring direction of the liquid in the second space 112 caused by the multiple first blades 6 rotating in the opposite direction relative to the partition 2 and making circular motion, which can drive the liquid in the second space 112 into the second filter space 321 through the second filter hole 322 on the back water side of the second cylinder 32, thereby effectively clearing and blocking the second filter hole 322 on the back water side of the second cylinder 32, and at the same time improving the efficiency of the filter cartridge 3 in further filtering the liquid in the second space 112.

[0052] The implementation principle of a floor-standing filter in the embodiment of the present application is: After the liquid to be filtered enters the first space 111 through the water inlet pipe 4, it contacts the plurality of first blades 6 in sequence, driving the partition plate 2 to rotate relative to the tank body 1, and at the same time, under the guidance of the guide surfaces 61 on the plurality of first blades 6, it flows toward the water outlet and enters the interior of the corresponding filter cartridge 3 through the water outlet; After the liquid to be filtered enters the interior of the filter cartridge 3, it first enters the first filter space 311 to be filtered by the first cartridge 31, then passes through the first filter hole 312 to enter the second filter space 321 to be filtered by the second cartridge 32, and then passes through the second filter hole 322 to enter the second space 112; When the plurality of filter cartridges 3 rotate with the partition plate 2 to make a circular motion and the outlet pipe 5 is used to discharge the liquid, the liquid in the second space 112 surges more, and the liquid re-entering the filter cartridge 3 can clear the impurities blocked on the first filter hole 312 or the second filter hole 322, so that the impurities fall into the sedimentation tank 323 under the action of gravity for collection; After the liquid to be filtered is subjected to multi-stage filtration inside the filter cartridge 3 , filtered liquid is obtained in the second space 112 and can be discharged through the water outlet pipe 5 .

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
