[0019] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] In this embodiment, if Figure 1 As shown, the online sewage filter device includes a filter box 1, a filter assembly 4, a liquid collecting hopper 7, a dirt collecting hopper 5, a drain pipe 3 and a sewage drive 6. A water inlet pipe 2 is arranged on the top of the filter box 1; the filter assembly 4 is arranged below the water inlet pipe 2, and the filter assembly 4 is used to filter sewage and discharge debris; the liquid collecting hopper 7 and the dirt collecting hopper 5 are both arranged below the filter box 1, and the sewage filtered by the filter assembly 4 can enter the liquid collecting hopper 7, and the debris discharged by the filter assembly 4 can enter the dirt collecting hopper 5; the drain pipe 3 is connected to the bottom of the liquid collecting hopper 7; the sewage drive 6 is connected to the bottom of the dirt collecting hopper 5 through a pipeline.

[0021] For example, the cross section of the filter box 1 is square, and the liquid collecting hopper 7 and the dirt collecting hopper 5 are sequentially arranged along the length direction of the filter box 1. Specifically, a bracket 14 is arranged at the bottom of the filter box 1, and the bracket 14 is used to support the filter box 1. For example, the bracket 14 includes a plurality of supporting legs, and the plurality of supporting legs are distributed at the bottom of the filter box 1.

[0022] For example, the sewage discharge driving member 6 is a slurry pump, and the debris in the sewage collecting hopper 5 can be automatically discharged through the slurry pump.

[0023] It can be understood that the sewage enters the interior of the filter box 1 from the water inlet pipe 2 at the top of the filter box 1, and enters the filter component 4 through the water inlet pipe 2. The filter component 4 can filter the sewage, and the filtered water enters the liquid collecting bucket 7, and can be transported to the next process through the drain pipe 3 at the bottom of the liquid collecting bucket 7. The filter component 4 transports the filtered debris to the sewage collecting bucket 5, and the debris in the sewage collecting bucket 5 can be discharged through the sewage discharge drive 6. When the sewage collecting bucket 5 discharges sewage, it does not affect the filtering of the sewage by the filter component 4, and can realize online sewage discharge without manual operation, which reduces labor intensity. The filter component 4 discharges the filtered debris in real time, does not affect the subsequent sewage filtration, and is conducive to improving the filtering effect.

[0024] In this embodiment, if Figure 1 As shown, a partition 11 is provided in the filter box 1 to form a first cavity and a second cavity in the filter box 1. The liquid collecting hopper 7 is located in the first cavity, and the dirt collecting hopper 5 is located in the second cavity.

[0025] In this embodiment, the liquid collecting hopper 7 and the dirt collecting hopper 5 are separated by a partition 11, the sewage filtered by the filter component 4 enters the liquid collecting hopper 7, and the debris filtered by the filter component 4 enters the dirt collecting hopper 5, which can prevent the debris from entering the liquid collecting hopper 7 and prevent the filtered sewage from splashing into the dirt collecting hopper 5, which is beneficial to ensure the filtering effect of the sewage.

[0026] In this embodiment, the liquid discharge outlet of the filter assembly 4 is located in the first cavity, and the impurity discharge outlet of the filter assembly 4 is located in the second cavity.

[0027] Specifically, the top of the partition 11 abuts against the top of the filter box 1, and the bottom of the partition 11 abuts against the bottom of the filter box 1. The filter assembly 4 passes through the partition 11, so that the liquid discharge outlet of the filter assembly 4 is located in the first cavity and the impurity discharge outlet is located in the second cavity.

[0028] It can be understood that the liquid discharge outlet of the filter component 4 is located in the first cavity, so that the sewage filtered by the filter component 4 can accurately enter the liquid collecting hopper 7. Similarly, the impurity discharge outlet of the filter component 4 is located in the second cavity, so that the impurities filtered by the filter component 4 can accurately enter the material collecting hopper.

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, the filter assembly 4 includes at least two conveying rollers 45, a filter mesh belt 41 and a conveying drive. At least two conveying rollers 45 are spaced apart along the arrangement direction of the liquid collecting hopper 7 and the dirt collecting hopper 5. Each conveying roller 45 is rotatably connected to the filter box 1 through a rotating shaft 43. The filter mesh belt 41 is annular, and the filter mesh belt 41 is wound around the conveying roller 45. The filter mesh belt 41 is provided with a plurality of spaced apart filter holes. The conveying drive is used to drive the filter mesh belt 41 to rotate around the conveying roller 45.

[0030] For example, two conveying rollers 45 are provided, and the two conveying rollers 45 are distributed in parallel and spaced apart. Specifically, one of the two conveying rollers 45 is located in the first cavity, and the other is located in the second cavity.

[0031] Specifically, Figure 2 As shown, the conveying roller 45 is a cylindrical structure, and the inner wall of the filter box 1 is provided with a rotating shaft 43, and the conveying roller 45 is rotatably connected to the bearing 44 through a bearing 44. For example, a rotating shaft 43 is respectively provided at both ends of each conveying roller 45, and one of the rotating shafts 43 is provided in the filter box 1 through a cover plate 46, and the cover plate 46 is provided outside the filter box 1. A sealing gasket is provided between the cover plate 46 and the filter box 1 to improve the sealing effect between the cover plate 46 and the outer wall of the filter box 1. The filter box 1 can be detachably connected to the outer wall of the filter box 1 by screws 48, which can facilitate the installation and removal of the conveying roller 45.

[0032] It should be noted that the filter assembly 4 includes a conveying roller 45, a filter mesh belt 41 and a conveying drive member forming a conveying device. Driven by the conveying drive member, the filter mesh rotates around the conveying roller 45. When the sewage falls onto the filter mesh belt 41, the filter mesh belt 41 can filter the sewage, and the filtered water falls through the filter holes on the filter mesh belt 41, so that the filtered water can enter the liquid collecting bucket 7 through the filter mesh belt 41, and the debris in the sewage falls onto the filter mesh belt 41. When the conveying drive member drives the filter mesh belt 41 to rotate around the conveyor belt, the filter mesh belt 41 can transport the debris to the debris output end of the filter assembly 4, and the debris falls into the sewage collecting bucket 5 at the output end.

[0033] In this embodiment, at least two conveying rollers 45 are distributed obliquely downward from the liquid collecting hopper 7 to the dirt collecting hopper 5 .

[0034] For example, the inclination angle of the filter belt 41 can be 25° to 65°, and can be 25°, 30°, 40°, 45°, 50°, 60° or 65°, etc. If the inclination angle of the filter belt 41 is too large, it is not convenient for the filtered water to fall through the filter holes, and if the inclination angle is too small, it is not convenient for the output of debris.

[0035] It can be understood that at least two conveying rollers 45 are tilted, so that the filter belt 41 wound on the conveying rollers 45 can be tilted. When sewage falls onto the filter belt 41, the debris in the sewage can slide downward under the action of gravity, so that the debris filtered by the filter component 4 is transported to the output end of the filter component 4.

[0036] In this embodiment, if Figure 1 and Figure 2 As shown, the conveying drive member includes a plurality of baffles 42, which are arranged on the conveying surface of the filter belt 41 at intervals along the conveying direction of the filter belt 41, so that the sewage falling on the filter belt 41 can push the filter belt 41 to convey the debris through the baffles 42.

[0037] It can be understood that since the filter mesh belt 41 on the filter mesh belt 41 is set at an angle, when sewage enters the filter mesh belt 41, it can generate an inclined downward thrust on the baffle 42, thereby driving the filter mesh belt 41 to rotate around the conveying roller 45. Driven by the filter mesh belt 41, the debris on the filter mesh belt 41 can move toward the output end, and then fall into the sewage collecting hopper 5 at the output end.

[0038] In this embodiment, the online sewage filtration device also includes a material blocking member (not shown in the figure), and material blocking members are arranged on both sides of the conveying direction of the filter mesh belt 41 to prevent debris on the filter mesh belt 41 from entering the gap between the filter mesh belt 41 and the filter box 1 through the material blocking member.

[0039] For example, the material blocking member may be a strip-shaped brush, which is arranged along the inclined direction of the conveyor mesh belt and has one end fixed to the inner wall of the filter box 1 and the other end extending to the filter mesh belt 41 .

[0040] It is understandable that by setting up a material blocking member, the gap between the filter mesh belt 41 and the inner wall of the filter box 1 can be blocked by the material blocking member, thereby preventing debris on the filter mesh belt 41 from passing through the gap between the filter mesh belt 41 and the inner wall of the filter box 1 and entering the liquid collecting bucket 7 to affect the filtering effect.

[0041] In this embodiment, the cross section of the liquid collecting hopper 7 gradually decreases from top to bottom. The cross section of the dirt collecting hopper 5 gradually decreases from top to bottom.

[0042] For example, the liquid collecting hopper 7 and the dirt collecting hopper 5 are both in the shape of a quadrangular pyramid.

[0043] It is understandable that the cross section of the liquid collecting hopper 7 gradually decreases from top to bottom, so that the filtered sewage in the liquid collecting hopper 7 can be concentrated to flow to the outlet at the bottom of the liquid collecting hopper 7, which is convenient for sewage discharge. Similarly, the cross section of the dirt collecting hopper 5 gradually decreases from top to bottom, which can make the debris discharge smoothly and concentrate it at the discharge port of the dirt collecting hopper 5, and then facilitate it to be transported to the next process under the drive of the sewage discharge drive 6.

[0044] In this embodiment, if Figure 1 As shown, an inspection door 12 is provided on the side wall of the filter box 1 .

[0045] Specifically, one side of the inspection door 12 is hinged to the side wall of the filter box 1 , and the other side can be detachably connected to the outer wall of the filter box 1 through a connecting piece to facilitate the opening and closing of the inspection door 12 .

[0046] By providing the inspection door 12 , when a component in the filter box 1 fails, it is convenient to inspect the component through the inspection door 12 .

[0047] In this embodiment, if Figure 1 As shown, a viewing window 13 is provided on the side wall of the filter box 1 .

[0048] For example, the viewing window 13 is made of transparent glass, a mounting opening is provided on the side wall of the filter box 1, and the viewing window 13 is mounted at the mounting opening.

[0049] It is understandable that by providing the viewing window 13, it is convenient to observe the operating conditions inside the filter box 1 through the viewing window 13, and it is convenient to observe emergencies in time, so as to respond in time and reduce losses.

[0050] When using the online sewage filter device of this embodiment, sewage enters the interior of the filter box 1 from the water inlet pipe 2 at the top of the filter box 1, and enters the filter belt 41 of the filter component 4 through the water inlet pipe 2. The filter component 4 can filter the sewage, and the filtered sewage falls into the liquid collecting bucket 7 through the filter holes on the filter belt 41. The filtered sewage is transported to the next process through the drain pipe 3 at the bottom of the liquid collecting bucket 7. At the same time, when the sewage impacts the baffle 42 on the filter belt 41, the baffle 42 can generate an inclined downward thrust. Driven by the baffle 42, the filter belt 41 transports the filtered debris to the output end and falls into the sewage collecting bucket 5 from the output end. The debris falling into the sewage collecting bucket 5 can be discharged through the sewage discharge driving member 6. When the sewage collecting bucket 5 discharges sewage, it does not affect the filtering of the sewage by the filter component 4, and can realize online sewage discharge. No manual operation is required, which reduces labor intensity. The filter component 4 discharges the filtered debris in real time, does not affect the subsequent sewage filtering, and is conducive to improving the filtering effect.
