Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and in particular relates to a large-flow water filtering device. Background Art

[0002] Wastewater filtration work usually involves the filtration of large-flow wastewater. Because the wastewater flow is large and the water pipeline is fixed, the flow rate of the wastewater will be relatively large, the water pressure is also relatively large, and the flow rate through the filter element is too fast. There is a problem of incomplete filtration due to the fast speed through the filter element, which makes the discharged wastewater substandard and causes environmental pollution. In addition, the filter element is directly connected to the water inlet channel and the water outlet channel. When the filter element needs to be replaced, the equipment needs to be shut down to replace the filter element, which reduces the water filtration efficiency. Utility Model Content

[0003] Based on the above background, the purpose of the utility model is to provide a large flow water filtering device.

[0004] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0005] A large flow water filtering device comprises a housing, wherein a partition plate is fixedly arranged in the middle of the housing, and the partition plate divides the interior of the housing into a first filter cartridge and a second filter cartridge;

[0006] The shell is provided with a water inlet pipe, which is a three-way pipe structure, one end of which extends into the partition plate, and the other two ends respectively penetrate the partition plate and extend into the first filter cartridge and the second filter cartridge, and the water inlet pipe is provided with a three-way valve;

[0007] A connecting pipe is provided in the first filter cartridge, one end of which is fixed on the partition plate, the connecting pipe is coaxially arranged with the water inlet pipe extending into the first filter cartridge, and the connecting pipe is a hollow water-permeable structure;

[0008] The first filter cartridge is provided with a filter assembly;

[0009] The filter assembly comprises a filter element, the filter element sleeve is arranged outside the connecting pipe, a plurality of arc-shaped baffles are arranged inside the filter element, and gaps are arranged between adjacent baffles;

[0010] A water outlet pipe is provided on the side of one end of the first filter cartridge close to the partition plate, and the water outlet pipe is radially away from one end of the water inlet pipe provided on the shell of the first filter cartridge;

[0011] The first filter cartridge and the second filter cartridge have the same internal structure and are symmetrically distributed around the partition plate;

[0012] The two ends of the shell are respectively threadedly connected with an upper end cover and a lower end cover.

[0013] Preferably, the baffles are provided in multiple layers along the radial direction from the connecting pipe toward the water outlet pipe, and the baffles in adjacent layers are staggered to further extend the filtering path of the liquid and improve the filtering effect.

[0014] Preferably, the water inlet pipe extending into the interior of the first filter cartridge is radially close to the inner wall of the first filter cartridge.

[0015] Preferably, a buffer plate is sleeved on the outside of the connecting tube, and the buffer plate is arranged between the connecting tube and the filter element. One end of the buffer plate is fixedly connected to the partition plate, and a gap is provided between the buffer plate and the connecting tube. The radial length of the buffer plate along the first filter cartridge is smaller than that of the first filter cartridge. After the liquid flows out through the hollow structure of the connecting tube, it flows along the axial direction of the connecting tube through the obstruction of the buffer plate to the end away from the partition plate and converges before flowing into the filter element. This can reduce the impact of the water flow on the filter assembly and provide better protection for the filter element.

[0016] Preferably, one side of the buffer plate is fixedly connected to the inner wall of the first filter cartridge, thereby increasing the buffer space for the liquid.

[0017] Preferably, sealing gaskets are provided on the inner walls of the upper end cover and the lower end cover close to the shell.

[0018] Preferably, the buffer plate is made of stainless steel and has strong impact resistance.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model can perform diversion filtration on the liquid to be filtered by providing a first filter cartridge and a second filter cartridge with the same internal structure and symmetrical arrangement. When the filter element needs to be replaced, one of the fluid channels can be closed for replacement while the other filter cartridge continues to filter without pausing the equipment, thereby improving the filtering efficiency.

[0021] 2. The utility model can effectively reduce the impact force of liquid from the water inlet pipe by arranging a connecting pipe and a buffer plate, thereby avoiding damage to the filter element due to excessive impact force on the filter element; a plurality of baffles are arranged in the filter element, and there are gaps between adjacent baffles. The liquid is blocked by the arc baffles and passes through the gaps between the adjacent arc baffles, thereby increasing the flow path of the liquid, increasing the filtration time, and improving the filtration effect.

[0039] like Figure 1-5 As shown, a large flow water filtering device comprises a housing 1, wherein a partition plate 2 is fixedly arranged in the middle of the housing 1, and the partition plate 2 divides the interior of the housing 1 into a first filter cartridge 11 and a second filter cartridge 12;

[0040] The housing 1 is provided with a water inlet pipe 3, which is a three-way pipe structure. One end of the water inlet pipe 3 extends into the partition plate 2, and the other two ends respectively penetrate the partition plate 2 and extend into the first filter cartridge 11 and the second filter cartridge 12. The water inlet pipe 3 is provided with a three-way valve.

[0041] The first filter cartridge 11 is provided with a connecting pipe 4, one end of which is fixed on the partition plate 2, and the connecting pipe 4 is coaxially arranged with the water inlet pipe 3 extending into the first filter cartridge 11, and the connecting pipe 4 is a hollow water-permeable structure;

[0042] The first filter cartridge 11 is provided with a filter assembly 5;

[0043] The filter assembly 5 includes a filter element 51, which is sleeved on the outside of the connecting pipe 4. A plurality of arc-shaped baffles 52 are arranged inside the filter element 51, and gaps are arranged between adjacent arc-shaped baffles 52.

[0044] A water outlet pipe 6 is provided on the side of one end of the first filter cartridge 11 close to the partition plate 2. The water outlet pipe 6 is radially away from one end of the water inlet pipe 3 provided on the housing 1 of the first filter cartridge 11.

[0045] The first filter cartridge 11 and the second filter cartridge 12 have the same internal structure and are symmetrically distributed around the partition plate 2;

[0046] The two ends of the housing 1 are respectively threadedly connected with an upper end cover 13 and a lower end cover 14 .

[0047] When in use, the liquid to be filtered flows into the first filter cartridge 11 and the second filter cartridge 12 through the water inlet pipe 3, and then flows out through the hollow structure of the connecting pipe 4. The impact force of the liquid can be well reduced from the water inlet pipe 3 to the connecting pipe 4. The liquid passes through the filter element 51 of the filter assembly 5. The filter element 51 is provided with an arc baffle 52. The liquid is blocked by the arc baffle 52 and passes through the gap between the adjacent arc baffles 52, which increases the flow path of the liquid, increases the filtering time, improves the filtering effect, and finally the filtered liquid flows out from the water outlet pipe 6. If the filter assembly 5 needs to be replaced, the switch of the water inlet pipe 3 is controlled by the three-way valve, the water inlet pipe 3 at one end of the filter assembly 5 to be replaced is closed, and the upper end cover 13 or the lower end cover 14 is rotated to replace the filter assembly 5 without suspending the equipment, thereby improving the filtering efficiency.

[0048] Preferably, the baffles 52 are provided in multiple layers along the radial direction from the connecting pipe 4 toward the water outlet pipe 6, and the baffles 52 in adjacent layers are arranged in a staggered manner, so as to further extend the filtering path of the liquid and improve the filtering effect.

[0049] Preferably, the water inlet pipe 3 extending into the first filter cartridge 11 is radially close to the inner wall of the first filter cartridge 11 .

[0050] Preferably, a buffer plate 7 is sleeved on the outside of the connecting tube 4, and the buffer plate 7 is arranged between the connecting tube 4 and the filter element 51. One end of the buffer plate 7 is fixedly connected to the partition plate 2, and a gap is provided between the buffer plate 7 and the connecting tube 4. The radial length of the buffer plate 7 along the first filter cartridge 11 is smaller than that of the first filter cartridge 11. After the liquid flows out through the hollow structure of the connecting tube 4, it flows along the axial direction of the connecting tube 4 to the end away from the partition plate 2 through the obstruction of the buffer plate 7, and then flows into the filter element 51, which can reduce the impact of the water flow on the filter assembly 5 and provide better protection for the filter element 51.

[0051] Preferably, one side of the buffer plate 7 is fixedly connected to the inner wall of the first filter cartridge 11, thereby increasing the buffer space of the liquid.

[0052] Preferably, a sealing gasket 8 is provided on the inner wall of the upper end cover 13 and the lower end cover 14 close to the shell 1 .

[0053] Preferably, the buffer plate 7 is made of stainless steel and has strong impact resistance.

[0054] The working process of the utility model is as follows: the liquid to be filtered flows into the first filter cartridge 11 and the second filter cartridge 12 through the water inlet pipe 3, and then flows out through the hollow structure of the connecting pipe 4. The impact force of the liquid can be well reduced from the water inlet pipe 3 to the connecting pipe 4. A buffer plate 7 is sleeved on the outer side of the connecting pipe 4. After being blocked by the buffer plate 7, the liquid flows along the axial direction of the connecting pipe 4 to the end away from the partition plate 2 and converges, and then flows into the filter element 51, further reducing the impact of the water flow on the filter component 5, and better protecting the filter element 51. The filter element 51 passes through the filter component 5. The filter element 51 is provided with an arc baffle 52. The liquid is blocked by the arc baffle 52 and passes through the gap between the adjacent arc baffles 52, thereby increasing the flow path of the liquid, increasing the filtration time, and improving the filtration effect. Finally, the filtered liquid flows out from the outlet pipe 6. If the filter assembly 5 needs to be replaced, the switch of the water inlet pipe 3 is controlled by the three-way valve, the water inlet pipe 3 at one end of the filter assembly 5 to be replaced is closed, and the upper end cover 13 or the lower end cover 14 is rotated to replace the filter assembly 5 without suspending the equipment, thereby improving the filtering efficiency.
