[0031] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] Please also read Figures 1 to 6 The present embodiment provides a fish pond sewage filter, comprising a shell 100, a conical filter cartridge 200, a sewage pipe 300 and a driving motor 400. The top of the shell 100 is covered with a top cover, and the interior of the shell 100 is divided into a filter chamber 120 and a sedimentation chamber 130 by a partition 110. The inner wall of the filter chamber 120 is provided with a clean water outlet 121, and the inner wall of the sedimentation chamber 130 is provided with a sewage outlet 131. The conical filter cartridge 200 is rotatably installed in the filter chamber 120, and the large mouth end 210 of the conical filter cartridge 200 passes through the partition 110 and is connected with the sedimentation chamber 130. One end of the sewage pipe 300 extends into the conical filter cartridge 200 through the small mouth end 220 of the conical filter cartridge 200, and a sewage outlet 310 is opened at one end of the sewage pipe 300. The driving motor 400 is drivingly connected to the large mouth end 210 of the conical filter cartridge 200, so as to drive the conical filter cartridge 200 to perform rotational filtration through the driving motor 400. Figure 4 As shown, the shape of the conical filter cartridge 200 is roughly conical, and the outer peripheral wall of the cylinder of the conical filter cartridge 200 is evenly provided with a plurality of triangular hollow openings, and the outer peripheral wall of the cylinder is provided with a filter screen 230 to filter sewage through the mesh of the filter screen 230.

[0033] It can be seen that the fish pond sewage filter of this embodiment transports the fish pond sewage to the conical filter barrel 200 through the sewage pipe 300, and then the driving motor 400 drives the conical filter barrel 200 to rotate to generate centrifugal force, so that the sludge impurities are thrown out from the large mouth end 210 of the conical filter barrel 200 and flow into the sedimentation bin 130 for sedimentation and discharged through the sewage outlet 131. During the rotation of the conical filter barrel 200, the water in the sewage is filtered and separated through the mesh of the conical filter barrel 200 and flows into the filter bin 120, thereby realizing the filtration and separation of sludge impurities and water. The rotating centrifugal dynamic filtration method is adopted to effectively improve the filtration efficiency, and the filtration effect is better. The filtered sludge impurities are concentrated in the sedimentation bin 130 for discharge, which can avoid secondary pollution and is convenient for users to use.

[0034] In this embodiment, a water baffle 132 is provided in the sedimentation bin 130, the water baffle 132 is arranged obliquely to the horizontal plane, and the water baffle 132 is located below the large mouth end 210 of the conical filter cartridge 200, and a spacing opening 138 is provided between the low end of the water baffle 132 and the inner wall of the sedimentation bin 130, so that the sludge impurities thrown out of the large mouth end 210 of the conical filter cartridge 200 fall on the water baffle 132 and flow along the water baffle 132 and through the spacing opening 138 to the bottom of the water baffle 132 for sedimentation, so that The water baffle plate 132 receives the sludge impurities thrown out by the large mouth end 210 of the conical filter cartridge 200, so that the sludge impurities flow stably along the water baffle plate 132 to the bottom thereof for sedimentation, effectively preventing the sludge impurities from being directly thrown into the sedimentation bin 130, causing the precipitated sludge impurities to be violently shaken or stirred and unable to settle. The water baffle plate 132 resists the impact of the sludge impurities thrown out by the large mouth end 210 of the conical filter cartridge 200, making the sedimentation of the sludge impurities more stable, thereby significantly improving the sedimentation effect.

[0035] Specifically, a sedimentation drain plate 133 is arranged in the sedimentation bin 130, and the sedimentation drain plate 133 is arranged inclined in the horizontal plane, and the sedimentation drain plate 133 is located below the water baffle plate 132 to form a sedimentation chamber between the water baffle plate 132 and the sedimentation drain plate 133, and the high end of the sedimentation drain plate 133 and the low end of the water baffle plate 132 are arranged in correspondence with each other up and down, and the drain outlet 131 is arranged adjacent to the low end of the sedimentation drain plate 133, so that the sludge impurities flow into the sedimentation drain plate 133 through the partition 138 of the water baffle plate 132 for sedimentation, and the drain outlet 131 is located at the low end of the sedimentation drain plate 133, so that the sludge impurities rely on their own gravity to slide from the high end of the sedimentation drain plate 133 to the low end of the sedimentation drain plate 133 and be discharged through the drain outlet 131.

[0036] The high end refers to an end of the inclined panel at a higher position, and the low end refers to an end of the inclined panel at a lower position.

[0037] Furthermore, the sewage outlet 131 is provided with an automatic sewage valve 139 to control the sewage outlet 131 to automatically discharge sludge impurities through the automatic sewage valve 139, which is beneficial to the concentrated sedimentation and discharge of sludge impurities.

[0038] Preferably, the sewage outlet 131 includes a sewage pipe 137 and a connecting port 136. A connecting port 136 is opened on the lower end of the sedimentation sewage plate 133. The connecting port 136 is connected to one end of the sewage pipe 137. The other end of the sewage pipe 137 extends through the inner wall of the sedimentation bin 130 and is exposed. In this way, the sludge impurities precipitated on the sedimentation sewage plate 133 can be discharged to the outside through the sewage pipe 137.

[0039] Optionally, the automatic sewage valve 139 includes a valve body 134 and a control end 135, the valve body 134 is arranged above the water baffle 132, and the control end 135 is embedded in the connecting port 136, so that the valve body 134 controls whether the connecting port 136 is flowing through the control end 135, thereby controlling the sewage outlet 131 to discharge sludge impurities, wherein the valve body 134 can be installed on the inner wall of the sedimentation bin 130, so as to drive the control end 135 to block the connecting port 136 through the valve body 134, thereby controlling the sewage outlet 131 to discharge sludge impurities.

[0040] In this embodiment, the sewage pipe 300 is arranged to extend in the transverse direction, and the end wall of the small end 220 of the conical filter cartridge 200 is provided with a central hole, and the sewage pipe 300 is passed through the central hole. The center position of the end wall 211 of the large end of the conical filter cartridge 200 is connected to the output shaft of the driving motor 400, and the end wall 211 of the large end of the conical filter cartridge 200 is provided with a hollow structure to form a sludge outlet 212, and the end wall of the small end 220 of the conical filter cartridge 200 is also provided with a hollow structure, wherein the driving motor 4 00 is arranged on the outer wall of the sedimentation bin 130, and the output shaft of the driving motor 400 extends into the sedimentation bin 130 and is connected to the large-mouth end wall 211 of the conical filter cartridge 200, so that the driving motor 400 drives the conical filter cartridge 200 to rotate and filter around the sewage pipe 300. In this way, the conical filter cartridge 200 can rely on centrifugal force to throw the sludge impurities from the sludge throwing outlet 212 into the sedimentation bin 130, and the filtered water flows into the filter bin 120 and is discharged through the clean water outlet 121.

[0041] Specifically, a plurality of sewage outlets 310 are provided at intervals on the wall of the sewage pipe 300 along its extension direction, and a cleaning pipe is provided inside the sewage pipe 300. A plurality of flushing holes are provided on the wall of the cleaning pipe. The diameter of the cleaning pipe is smaller than the diameter of the sewage pipe 300. A water pump is provided at the other end of the sewage pipe 300. The water pump is placed in the fish pond so that the sewage in the fish pond can be pumped into the conical filter cartridge 200 for filtration through the water pump. In order to avoid clogging of the mesh of the conical filter cartridge 200, clean water is sprayed into the conical filter cartridge 200 through the cleaning pipe to flush the mesh of the conical filter cartridge 200.

[0042] Furthermore, the partition 110 is provided with a through hole 111 so that the large mouth end 210 of the conical filter cartridge 200 passes through the through hole 111 and extends into the sedimentation bin 130, and a water-retaining brush 112 is arranged along the peripheral position of one end of the through hole 111 facing the filter bin 120, so that the water-retaining brush 112 blocks the water filtered out of the filter bin 120 from flowing into the sedimentation bin 130 through the gap between the conical filter cartridge 200 and the through hole 111, so that the sedimentation bin 130 and the filter bin 120 are relatively separated and do not affect each other, and the spatial arrangement is reasonable, which is convenient for fish pond sewage filtration.

[0043] In this embodiment, at least one oxygen tube 600 is provided in the outer shell 100. The oxygen tube 600 passes through the filtration bin 120 and the sedimentation bin 130, and both ends of the oxygen tube 600 are exposed from opposite sides of the outer shell 100, so that oxygen can be filled into the fish pond through the oxygen tube 600 to facilitate the breeding of fish animals. In addition, a water and power outage alarm 500 is provided in the outer shell 100. When there is a water and power outage, an alarm is issued in time to notify the user to maintain the fish pond environment to avoid damage to the fish in the fish pond.

[0044] When in use, the sewage in the fish pond is pumped into the conical filter cartridge 200 through the sewage pipe 300 by the water pump, and the conical filter cartridge 200 is driven to rotate by the driving motor 400. While the conical filter cartridge 200 rotates, the water is filtered into the filter bin 120 through the mesh holes on the peripheral wall of the conical filter cartridge 200, and the sludge impurities are automatically thrown out from the large mouth end 210 of the conical filter cartridge 200 by the rotating centrifugal force and concentrated into the sedimentation bin 130 for sedimentation, thereby realizing the automatic separation of sludge impurities and water. The rotary filtration is more efficient and convenient for maintaining and cleaning the fish pond water environment. The filtered water is discharged through the clean water outlet 121 and can be reused, and the sludge impurities are collected in the sedimentation bin 130 for centralized treatment to avoid secondary pollution.

[0045] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0046] The fish pond sewage filter of the utility model conveys the fish pond sewage to the conical filter barrel 200 through the sewage pipe 300, and then the driving motor 400 drives the conical filter barrel 200 to rotate to generate centrifugal force, so that the sludge impurities are thrown out from the large mouth end 210 of the conical filter barrel 200 and flow into the sedimentation bin 130 for sedimentation and discharged through the sewage outlet 131. During the rotation of the conical filter barrel 200, the water in the sewage is filtered and separated through the mesh of the conical filter barrel 200 and flows into the filter bin 120, thereby realizing the filtration separation of the sludge impurities and water. The rotary centrifugal dynamic filtration method is adopted to effectively improve the filtration efficiency, and the filtration effect is better. The filtered sludge impurities are concentrated in the sedimentation bin 130 for discharge, which can avoid secondary pollution and is convenient for users to use.
