The floor type filter is named after its installation method, i.e. directly placed on the ground, instead of being hung or installed on other structures.

[0003] The existing floor type filter usually includes a tank body, a partition plate, a plurality of filter cartridges, a water inlet pipe and a water outlet pipe. The inside of the tank body has a cavity, the partition plate divides the cavity into two spaces above and below, the water inlet pipe and the water outlet pipe are connected with the tank body and communicate with the space above and below the partition plate respectively; a plurality of filter cartridges are installed on the partition plate and located in the space below the partition plate, the liquid to be filtered enters the space above the partition plate in the cavity through the water inlet pipe, and then enters the plurality of filter cartridges for filtering, the filtered liquid flows out of the filter cartridges in the space below the partition plate in the cavity, and finally is discharged through the water outlet pipe.

[0004] However, due to its large size, the floor type filter usually does not need to clean the filter cartridges inside frequently, if some filter cartridges are blocked, other filter cartridges can still filter the liquid, but the filtering efficiency of the floor type filter will be significantly affected.

[0049] With reference to Figure 2 and Figure 4 , the filter cartridge 3 includes a first cylinder 31 and a second cylinder 32, and the first cylinder 31 and the second cylinder 32 are both hollow cylindrical structures.

[0050] The first cylinder 31 has a first filter space 311 inside, the first filter space 311 is formed with an opening at one end of the first cylinder 31 along the axis direction of the first cylinder 31, and after the first cylinder 31 is installed on the partition plate 2, the first filter space 311 can communicate with the corresponding water inlet 21 through the opening of the first filter space 311, so as to realize the communication between the first filter space 311 and the first space 111; the surface of the first cylinder 31 is uniformly distributed with a plurality of first filter holes 312 for the first filter space 311 to communicate with the space outside the first cylinder 31, and the plurality of first filter holes 312 are respectively distributed on the circumferential side of the radial direction of the first cylinder 31 and the end of the first cylinder 31 away from the opening of the first filter space 311. In the embodiment, preferably, the first filter hole 312 is a circular hole, and the hole diameters of the plurality of first filter holes 312 are equal.

[0051] The second cylinder body 32 has a second filtering space 321 inside. The second filtering space 321 is formed with an opening at one end of the second cylinder body 32 along the axial direction of the second cylinder body 32. After the second cylinder body 32 is installed on the partition plate 2, the opening of the second filtering space 321 is upward, and the second cylinder body 32 is sleeved with the first cylinder body 31. At this time, the first cylinder body 31 is located in the second filtering space 321, and the first filtering space 311 can communicate with the corresponding second filtering space 321 through the plurality of first filtering holes 312. At this time, the axis of the first cylinder body 31 coincides with the axis of the corresponding second cylinder body 32, and the first cylinder body 31 maintains a distance from the inner wall of the corresponding second filtering space 321. The surface of the second cylinder body 32 is uniformly distributed with a plurality of second filtering holes 322 for the second filtering space 321 to communicate with the second space 112. The plurality of second filtering holes 322 are only distributed on the circumferential side of the second cylinder body 32 in the radial direction. In this embodiment, the second filtering hole 322 is preferably also a circular hole, and the hole diameter size of the second filtering hole 322 is smaller than the hole diameter size of the first filtering hole 312.

[0052] The second cylinder body 32 is further provided with a deposition groove 323 at the end of the second filtering space 321 away from the opening thereof for the impurities separated from the liquid to be collected. The plurality of second filtering holes 322 on the second cylinder body 32 are all located above the deposition groove 323. The impurities in the second filtering space 321 can move downward to the deposition groove 323 under the action of gravity.

[0053] Referring to Figure 2 and Figure 3 , the partition plate 2 is further provided with a plurality of first vanes 6, and the plurality of first vanes 6 are all located in the first space 111. The first vane 6 is in the shape of an arc. The arc track direction of the first vane 6 is perpendicular to the axis of the partition plate 2. The plurality of first vanes 6 are arranged in a circular array on the partition plate 2 with the axis of the partition plate 2 as the axis. The plurality of first vanes 6 are fixedly connected to each other at the end of the arc track of the first vane 6 close to the axis of the partition plate 2. There is a distance between the end of the arc track of the first vane 6 away from the axis of the partition plate 2 and the inner wall of the first space 111. In this embodiment, the number of the plurality of first vanes 6 installed on the partition plate 2 is equal to the number of the plurality of water inlets 21 on the partition plate 2. A water inlet 21 is provided on the partition plate 2 at a position between adjacent first vanes 6.

[0054] 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 aligned with the plurality of first vanes 6 in the horizontal direction. The water outlet direction of the water inlet pipe 4 is eccentric with respect to the axis of the tank body 1.

[0055] One side of the first vane 6 has a guide surface 61 for the liquid flowing into the first space 111 through the water inlet pipe 4 to contact, and the guide surface 61 is an arc surface; after the liquid flows into the first space 111 through the water inlet pipe 4, the liquid can actively contact the guide surface 61 on the first vane 6, at this time, the force exerted by the liquid on the guide surface 61 can drive the partition plate 2 to rotate relative to the tank body 1, so that the liquid continuously entering the first space 111 through the water inlet pipe 4 can be in turn contacted with the guide surfaces 61 on the plurality of first vanes 6, and the cycle is repeated; at the same time, in the process of the liquid exerting force on the guide surface 61, the guide surface 61 can guide the liquid to flow along the guide surface 61 towards the direction close to the adjacent water inlet 21, facilitating the liquid to enter the filter cartridge 3 through the water inlet 21 for filtration.

[0056] When the filter cartridge 3 is filtering the liquid, if the first filter hole 312 or the second filter hole 322 is blocked by impurities, in the process that the filter cartridge 3 rotates with the partition plate 2 in the second space 112 to make a circular motion around the axis of the partition plate 2, the liquid in the second space 112 can be promoted to enter the second filter space 321 through the second filter hole 322 or the liquid in the second filter space 321 can be promoted to enter the first filter space 311 through the first filter hole 312, at this time, the impurities causing the blockage of the first filter hole 312 or the second filter hole 322 can be driven away from the corresponding first filter hole 312 or second filter hole 322 by the action of the liquid, so as to achieve the effect of unblocking.

[0057] Further, the plurality of second filter holes 322 on the second cylinder body 32 are preferably different in size.

[0058] In the process that the filter cartridge 3 rotates with the partition plate 2 to make a circular motion, the position of the second cylinder body 32 that actively contacts with the liquid is the water-facing side, and the other positions are the water-backing side. The size of the second filter hole 322 on the second cylinder body 32 close to the water-facing side is larger than the size of the second filter hole 322 on the second cylinder body 32 close to the water-backing side, and the size of the second filter hole 322 on the second cylinder body 32 gradually decreases from the water-facing side to the water-backing side.

[0059] At this time, the liquid flowing from the first space 111 into the second space 112 can be filtered to the lowest extent by the filter cartridge 3 (sufficient to meet the required filtering demand), and in the process that the plurality of filter cartridges 3 rotate with the partition plate 2 to make a circular motion, the filter cartridge 3 can further filter the liquid in the second space 112 to a higher extent, further improving the filtering effect on the liquid.

[0060] Referring to Figure 2 and Figure 4 , the partition plate 2 is further provided with a rotating shaft 7 and a plurality of second vanes 8, and the rotating shaft 7 and the plurality of second vanes 8 are located in the second space 112.

[0061] The rotating shaft 7 is in a cylindrical structure, and is rotationally connected with the partition plate 2. The rotating shaft 7 line of the rotating shaft 7 coincides with the axis of the rotating shaft 7 and the axis of the partition plate 2. At this time, the rotating shaft 7 is surrounded by the plurality of filter cartridges 3. The plurality of second vanes 8 are installed at the end of the rotating shaft 7 away from the partition plate 2. The second vanes 8 are in a rectangular sheet structure. The plurality of second vanes 8 are arranged in a circular array on the rotating shaft 7 with the axis of the rotating shaft 7 as the axis. The length direction of the second vanes 8 is the same as the radial direction of the second vanes 8 relative to the rotating shaft 7. During the circular motion of the plurality of second vanes 8 along the axis of the rotating shaft 7, the end of the second vanes 8 away from the rotating shaft 7 maintains a certain distance with the adjacent filter cartridge 3.

[0062] The water outlet pipe 5 is fixedly connected with 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 plurality of second vanes 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. 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.

[0063] Referring to Figure 3 and Figure 4 During the process that the filtered liquid in the second space 112 is discharged through the water outlet pipe 5, the liquid in the second space 112 flows into the water outlet pipe 5, which can sequentially apply force to the plurality of second vanes 8, so that the plurality of second vanes 8 rotate relative to the partition plate 2 through the rotating shaft 7 to make circular motion. The direction of the circular motion of the plurality of second vanes 8 is opposite to the direction of the circular motion of the plurality of first vanes 6.

[0064] At this time, the direction of the agitation of the plurality of filter cartridges 3 to the liquid in the second space 112 is opposite to the direction of the agitation of the plurality of first vanes 6 to the liquid in the second space 112. The liquid in the second space 112 can be driven to enter the second filter space 321 through the second filter hole 322 of the second cylinder body 32 close to the backwater side, so that the second filter hole 322 close to the backwater side on the second cylinder body 32 can be effectively unclogged, and the efficiency of the filter cartridge 3 in further filtering the liquid in the second space 112 can be improved.

[0065] The implementation principle of the floor type filter in the embodiment of the application is as follows:

[0066] After the liquid to be filtered enters the first space 111 through the water inlet pipe 4, the liquid sequentially contacts the plurality of first vanes 6, drives the partition plate 2 to rotate relative to the tank body 1, and flows to the water outlet under the guidance of the guide surface 61 on the plurality of first vanes 6, and then enters the inside of the corresponding filter cartridge 3 through the water outlet.

[0067] After the liquid to be filtered enters the interior of the filter cartridge 3, it first enters the first filter space 311 and is filtered by the first cylinder 31, then passes through the first filter hole 312 and enters the second filter space 321 and is filtered by the second cylinder 32, and then passes through the second filter hole 322 and enters the second space 112;

[0068] During the process of the plurality of filter cartridges 3 rotating with the partition plate 2 and the water outlet pipe 5 being used to discharge the liquid, the degree of the liquid in the second space 112 being stirred increases, the liquid re-entering the interior of the filter cartridge 3 can clear the blockage of the impurities clogging the first filter hole 312 or the second filter hole 322, and the impurities fall to the sediment groove 323 under the action of gravity and are collected;

[0069] After the liquid to be filtered is filtered by multiple stages in the interior of the filter cartridge 3, the filtered liquid in the second space 112 can be discharged through the water outlet pipe 5.

[0070] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
