[0002] Currently, the oil removal and sedimentation functions of water supply and sewage treatment processes are generally achieved through gravity or pressure oil removal tanks, sedimentation tanks, or oil removal sedimentation tanks. The filtration function is generally achieved through independently set pressure or gravity filtration buildings (structures). The treatment process is long and involves many buildings (structures), which increases the operating cost of water supply and sewage treatment projects.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the integrated oil removal, settling, and filtration device of this utility model may include a tank 12 and at least two sets of filter components. The tank 12 has an inlet 1 on one side, an oil collection port 9 at the top, and a sludge discharge port 3 and at least two outlets 2 at the bottom. Each filter component includes a filter tube 6, which is inserted into the tank 12. One end of the filter tube 6 is sealed to the tank 12, and the other end is connected to the corresponding outlet 2. The filter tube 6 has through-holes in its tube body.

[0027] Specifically, tank 12 is the main body of the entire device, and the interior of tank 12 serves as a separation zone for oil removal, sedimentation, and filtration. The inlet 1 on one side of tank 12 is used to introduce wastewater requiring oil removal, sedimentation, and filtration into the tank 12; the oil collection port 9 at the top of tank 12 collects suspended oil on the liquid surface to achieve oil removal; the sludge discharge port 3 at the bottom of tank 12 collects sludge settled at the bottom to achieve sedimentation; the filtration assembly uses the filter holes of filter pipe 6 to block impurities in the separation zone between the outside of filter pipe 6 and the inner wall of tank 12 to achieve filtration; and multiple sets of filtration assemblies are installed inside tank 12, so that the liquid after oil removal and sedimentation can be filtered through the filter holes of filter pipe 6 and then enter filter pipe 6. The filtered liquid is then discharged through the outlet 2, which connects to the end of filter pipe 6, to quickly complete filtration and improve treatment efficiency.

[0028] Overall, the integrated oil removal, sedimentation, and filtration device combines oil removal, sedimentation, and filtration processes into one through its structural design. This shortens the processing flow, reduces the number of buildings and structures to be treated, and lowers the investment cost of engineering construction. It is suitable for water supply and sewage treatment projects. Furthermore, by designing multiple sets of filtration components within the tank 12, it can improve the single-tank treatment efficiency and further reduce the operating costs of water supply and sewage treatment projects.

[0029] Furthermore, the number of oil collection ports 9 at the top of the tank 12 and sludge discharge ports 3 at the bottom can be multiple, such as 2, 3 or 4, depending on the size of the tank 12 and the amount of wastewater to be treated. Of course, the number of water inlets 1 on one side of the tank 12 can also be increased appropriately depending on the specific situation.

[0030] In one example, the filter assembly also includes a filter layer 13, which is fitted onto the outer wall of the filter tube 6.

[0031] Specifically, the filter assembly, by covering the outer wall of the filter tube 6 with a filter layer 13, forms a two-stage filtration system in conjunction with the filter holes in the filter tube 6. The filter layer 13, with its different filter media, can adsorb and remove dissolved organic matter, heavy metal ions, and phosphorus compounds, thereby improving the water purification effect. At the same time, the filter layer 13 is evenly distributed on the outside of the filter tube 6, and can effectively remove pollutants trapped in the filter media through rinsing or backwashing, so as to restore the filtration capacity of the filter layer 13.

[0032] Furthermore, the filter layer 13 can be made of organic or inorganic materials. The filter layer 13 is an existing device, and its specific structure will not be described in detail here.

[0033] In one example, the tank 12 has a horizontal structure, with multiple sets of filter components distributed horizontally, and the filter tubes 6 of each set of filter components are installed vertically. This design increases the number of filter components inside the tank 12, thereby improving the processing efficiency of a single tank.

[0034] In one example, the top of the tank 12 has a mounting hole, into which the sealing end of the filter tube 6 is detachably installed. The mounting hole design of the tank 12 facilitates the installation of the filter tube 6, and also facilitates maintenance and repair.

[0035] In one example, the sealing end of the filter pipe 6 is provided with a first flange 14, the side of the first flange 14 near the tank body 12 is connected to a second flange 10 at the mounting hole, and the side of the first flange 14 away from the tank body 12 is sealed by a blind flange 11.

[0036] Specifically, the sealing end of the filter tube 6 extends radially outward to form a first flange 14, and the edge of the mounting hole also extends radially outward to form a second flange 10. The integrated device also includes a blind flange 11 that matches the first flange 14 and the second flange 10. In this way, the blind flange 11, the first flange 14 and the second flange 10 are fixedly connected in sequence by bolts, so that the sealing end of the filter tube 6 can be detachably installed in the mounting hole and sealed.

[0037] In one example, the end of the filter tube 6 near the outlet 2 is a spigot 8, and the bottom of the tank 12 is provided with a socket 5 that communicates with the outlet 2. The socket 5 matches the spigot 8.

[0038] Specifically, the filter tube 6 is connected to the socket 5 at the outlet 2 via the spigot 8. The structure is simple and easy to install, and it is easy to quickly inspect or replace. In addition, the annular gap filling technology provides good sealing performance, which can effectively connect the filter tube 6 and the outlet 2 while ensuring the filtration effect of the filter tube 6.

[0039] In one example, a sealing ring 4 is provided between the socket 5 and the spigot 8 to improve the sealing performance at the connection between the filter pipe 6 and the outlet 2.

[0040] In one example, the integrated device also includes a water inlet main 15 and at least two sets of cleaning components. The water inlet main 15 extends into the tank through the side wall of the tank body 12. Each set of cleaning components is installed on the water inlet main 15 inside the tank body 12 and corresponds one-to-one with the filter components.

[0041] Specifically, the integrated device has a cleaning assembly for each filter assembly to facilitate effective rinsing. All cleaning assemblies are installed on the inlet water main 15, through which rinsing water is introduced from outside the tank 12. This simplifies the rinsing structure of the integrated device while ensuring rinsing effectiveness.

[0042] In one example, the cleaning assembly includes at least one flushing water pipe 7 connected to the inlet water main 15, and the flushing water pipe 7 is provided with a plurality of nozzles 16, the spray direction of the nozzles 16 being toward the outer wall of the filter pipe 6.

[0043] Specifically, the flushing water pipe 7 is installed on and connected to the inlet water main pipe 15. The flushing water pipe 7 is used to guide the flushing water to the corresponding position for flushing. The flushing water pipe 7 sprays flushing water onto the outer wall of the filter pipe 6 through the nozzle 16, which can increase the water flow pressure of the flushing water. The arrangement of multiple nozzles 16 can increase the range of flushing the outer wall of the filter pipe 6.

[0044] In one example, multiple flushing water pipes 7 are evenly distributed around the circumference of the filter pipe 6, with the axial direction of each flushing water pipe 7 being the same as that of the filter pipe 6, and multiple nozzles 16 on the flushing water pipes 7 being evenly distributed along their axial direction. This design allows the flushing water sprayed by the cleaning assembly through the nozzles 16 to cover the outer wall of the filter pipe 6 as completely as possible (and the outer side of the filter layer 13 when there is one), so as to effectively remove the contaminants trapped by the filter assembly and restore the filtration capacity of the filter assembly.

[0045] To better understand the above embodiments, the working process of the integrated device of this utility model will be further explained below with reference to the accompanying drawings.

[0046] The oil removal and sedimentation filtration process: Water enters the separation zone inside tank 12 through inlet 1. In the separation zone, oil removal and sedimentation occur. Oil with a density less than water floats to the surface and is collected and discharged through oil collection port 9. Sludge with a density greater than water sinks to the bottom of tank 12 and is collected and discharged through sludge discharge port 3. The water in the separation zone is filtered through the filter layer 13 covering the outer wall of filter pipe 6, then flows from the outer wall of filter pipe 6 into the filter pipe 6 through filter holes, and finally exits through outlet 2.

[0047] Cleaning of filter layer 13: When the filter layer 13 covering the outer wall of filter pipe 6 needs surface cleaning, the integrated device can still operate normally or backwash. The flushing water is distributed from the inlet main pipe 15 into the flushing water pipe 7 and sprayed by the nozzle 16 to clean the surface of filter layer 13. When the filter layer 13 needs backwashing, the integrated device stops operating normally. The backwashing water enters the filter pipe 6 from the outlet 2, passes through the filter holes from the inner wall of the filter pipe 6 to the outer wall, and passes through the filter layer 13, so that the filter layer 13 is backwashed. The backwashing wastewater enters the separation zone of tank 12 and is discharged through the sludge discharge port 3. After the backwashing is completed, the integrated device resumes normal operation.

[0048] Installation of filter tube 6: Filter tube 6 can be arranged in any direction within the tank 12, and the specific number can be determined according to the processing capacity. One end of filter tube 6 is a socket connection, and the other end is a flange connection; the socket 5 is fixed to the tank 12 and communicates with the outlet 2. The spigot 8 of filter tube 6 is inserted into the socket 5 and sealed by the sealing ring 4; the first flange 14 at the flange connection end is fixedly connected to the second flange 10 and the blind flange 11 at the mounting hole by bolts, and the blind flange 11 is used to achieve sealing. During maintenance and repair, the blind flange 11 can be removed, and the filter tube 6 can be pulled out from the mounting hole for maintenance or replacement.

[0049] The advantages of the integrated device of this utility model compared with the prior art include at least the following:

[0050] This utility model's integrated device combines pressure oil removal, sedimentation, and filtration processes into a single structure, shortening the processing flow and reducing the number of processing buildings. It is suitable for water supply and sewage treatment projects, achieving the goal of improving the treatment efficiency of a single tank and reducing the investment and operating costs of water supply and sewage treatment projects. This integrated device can still operate normally or be backwashed when the filter layer is surface cleaned. The filter pipe is installed with a socket, facilitating quick maintenance or replacement.
