[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a novel fiberglass filter includes a tank 1. The top of the tank 1 is connected to a top cover 2 via a flange. Sealing rings are installed on the mating surfaces of the two flanges. An upwardly protruding filter media inlet 3 is integrally formed on the top of the tank 1. A sewage inlet 4 protruding obliquely upward is integrally formed on the side of the top of the tank 1. The filter media inlet 3 and the sewage inlet 4 are connected to the inner cavities of the tank 1 and the top cover 2. A downwardly protruding outlet 6 is integrally formed at the center of the bottom end of the tank 1. The inner cavity of the outlet 6 is connected to the inner cavity of the tank 1. A filter media receiving mechanism is installed on the lower inner wall of the tank 1. Multiple support seats 8 are welded to the lower inner wall of the tank 1 to support the bottom of the receiving tank 5. The multiple support seats 8 are equidistantly distributed in the circumferential direction. A distribution plate 14 is fixedly installed on the inner wall of the tank 1 above the filter media receiving mechanism. The bottom of the filter media inlet 3 extends through to the lower part of the distribution plate 14.

[0022] In this embodiment: First, when installing the filter media receiving mechanism, the top cover 2 is in the open state. The filter media receiving mechanism is placed into the inside of the tank 1 through the top opening of the tank 1. After the filter media receiving mechanism is placed, multiple support seats 8 support the filter media receiving mechanism. After the filter media receiving mechanism is installed, the top cover 2 is connected to the top of the tank 1. Then, particulate filter media can be added into the filter media receiving mechanism through the filter media inlet 3. The filter media is effectively filled into the device, and the top filter media is located in the filter media inlet 3. When filtering sewage, the sewage is pumped into the tank 1 through the sewage inlet 4. The sewage comes into contact with the filter media in the filter media receiving mechanism. During this process, impurities in the sewage are effectively filtered. The filtered sewage passes under the filter media receiving mechanism and is discharged downward from the outlet 6.

[0023] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 and Figure 5The filter media receiving mechanism includes a receiving tank 5 fixedly installed on the inner wall of the tank body 1. The top of the receiving tank 5 has a conical structure that is wider at the top and narrower at the bottom, and the diameter of the top of the conical surface of the receiving tank 5 is equal to the diameter of the inner wall of the tank body 1. The lower half of the inner wall of the receiving tank 5 has a conical structure that is wider at the top and narrower at the bottom. The bottom end of the lower conical surface of the receiving tank 5 is integrally formed with a downward protruding intercepting net 7. The intercepting net 7 has a porous structure, and the bottom output end of the intercepting net 7 is integrally formed with a connecting port 9 extending into the inner cavity of the discharge port 6.

[0024] In this embodiment: the two conical structures of the receiving tank 5 facilitate smoother discharge of the filter media and reduce obstruction. When the filter media needs to be replaced, the pipe connected to the discharge port 6 is disassembled until the discharge port 6 is no longer blocked by the pipe. At this time, the sealing plate 11 at the bottom of the connection port 9 can be disassembled, and the filter media can be discharged downward under gravity. At the rear end of the discharge process, a high-pressure water gun can be used for auxiliary rinsing. High-pressure water is flushed in from the filter media inlet 3 to flush out the undischarged filter media from the connection port 9. After the filter media is discharged, the sealing plate 11 is reconnected, and new filter media can be added through the filter media inlet 3.

[0025] After the sewage enters the tank 1 through the sewage inlet 4, it moves downward through the distribution plate 14. The distribution plate 14 can make the sewage fall as evenly as possible and achieve uniform contact with the filter media. After being filtered, the filtered water falls from the interception net 7.

[0026] Please refer to this carefully. Figure 4 and Figure 5 A connecting seat 10 protruding outward is integrally formed on the lower part of the outer wall of the connecting port 9. A guide cone surface is integrally formed on the top of the connecting seat 10. There is a channel for fluid to flow downward between the outer periphery of the connecting port 9, the connecting seat 10, the sealing plate 11 and the inner periphery of the discharge port 6.

[0027] In this embodiment: the filtered water falls from the interception net 7 and enters the channel to be discharged outward, and the design of the guide cone surface can reduce the resistance of water discharge.

[0028] Please refer to this carefully. Figure 5 The bottom end of the connecting seat 10 is integrally formed with a downward protruding stud 12. The outer wall of the stud 12 is slidably mounted with a sealing plate 11 that mates with the bottom end of the connecting seat 10. The outer wall of the stud 12 is threaded with a nut 13. A sealing ring is installed on the mating surface between the sealing plate 11 and the connecting seat 10.

[0029] In this embodiment, the sealing plate 11 is fixed by tightening the nut 13. After the nut 13 is removed, the sealing plate 11 can be removed.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
