Description

Fish tank filter

Technical Field

The utility model relates to a fish bowl filter equipment technical field especially relates to a fish bowl filter.

Background

The fish tank filter is a product for removing dirt such as excrement in water in a fish culture appliance, the fish tank filter can separate and precipitate by utilizing the dead weight of water flow and solid, the water flow is decelerated through the large gap between the flow baffle plate and the overflow plate, in addition, the dead weight of garbage precipitates at the bottom, and then the garbage is discharged through forced discharge. The fish tank filter is used as solid-liquid separation equipment and is provided with a water feeding area, a water turning area and an overflow area, and fish feces are precipitated below the water turning area. The water pump in the lower filtering bin is started, water is injected into the culture area in the fish tank from the water feeding pipe, the water level of the culture area of the fish tank is increased, due to the water retaining effect of the water retaining pipe, the water level difference is generated between the water in the culture area and the water in the water retaining pipe, and the water in the water retaining pipe flows into the water turning area from the overflow water suction port along with the water flow according to the principle of the communicating device, so that the water sinks into the bottom of the fish tank filter due to the gravity, and the water flow rises from the water turning area at the gap between the water retaining pipe and the overflow pipe and flows out from the overflow pipe, passes through the filtering cotton of the lower filtering bin and flows into the lower filtering bin, and the water circulation is completed. The fish feces are deposited at the bottom of the fish tank filter and are discharged periodically, so that the effect of solid-liquid separation is achieved.

The existing fish tank filter has the disadvantages that because the water turning area is communicated with the settling area, a part of fish can rise along with rising water flow, and because the space of the settling area of the fish tank filter is small, the fish can be accumulated to expose the settling area and enter the water turning area, so the settling effect is not ideal; meanwhile, the sedimentation effect of the existing fish tank filter is related to the water flow speed, the faster the water flow is, the poorer the effect is, and on the contrary, the slower the water flow is, the better the effect is, but the flow of water circulation can be influenced.

By connecting the water source, water is injected into the fish tank 4 through the water supply pipe 11. The water supply pipe 11 can supplement water loss caused by water discharged by the fish tank filter; meanwhile, the water feeding pipe 11 is arranged in the overflow drain pipe 2 and can increase the integrity of the fish tank filter through the limit of the connecting piece 901, so that the occupation of the volume in the fish tank 4 is reduced, the small fish tank 4 can use the fish tank filter, and the application range of the product is enlarged.

To sum up, the utility model provides a fish bowl filter, including retaining pipe 1, overflow drain pipe 2 and sedimentation pipe 3, the overflow drain pipe 2 outside is located to retaining pipe 1 cover, and overflow drain pipe 2's external diameter is less than retaining pipe 1's internal diameter, and 2 tops of overflow drain pipe and 1 top of manger plate pipe intercommunication, the height that highly is less than retaining pipe 1 delivery port of 2 water inlets of overflow drain pipe, the one end and the manger plate pipe 1 intercommunication of sedimentation pipe 3, the other end of sedimentation pipe 3 be used for with fish bowl 4 bottom intercommunication. When the device works, fish at the bottom of the fish tank 4 firstly enters the sedimentation pipe 3 for sedimentation and then enters the water retaining pipe 1 and the overflow drain pipe 2 for water circulation. Compared with the existing fish tank filter, the settling tank is directly arranged below the water blocking pipe 1, water in the fish tank 4 firstly enters the settling pipe 3 to settle fish feces, so that the amount of the fish feces entering the water blocking pipe 1 along with ascending water flow is reduced, and the settling effect of the fish feces is enhanced; meanwhile, the sedimentation pipe 3 can increase the volume of a fish excrement sedimentation area, the situation that the fish excrement is accumulated and flows out of the sedimentation tank to cause unsatisfactory cleaning effect due to the fact that the sedimentation space of the fish tank filter is too small is prevented, and the design prolongs the cleaning period of the excrement in the fish tank 4; in addition, when the water flow is larger, the reduction of the deposition effect of fish feces caused by the increase of the disturbance of the water is reduced. The utility model discloses a set up sedimentation tube 3, improved the just deposit effect of collecting of fish and increased just deposit region's of fish volume, prolonged clearance cycle.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
