Description

Technical Field

[0001] The utility model relates to the field of sewage filtration, in particular to a sewage filter for an aquarium or a breeding box. Background Art

[0002] In home aquariums and breeding tanks, due to the life traces of ornamental fish, more ammonia nitrogen and nitrite will be produced in the water. These pollutants are important components that affect the survival of fish. For this reason, some companies have designed a filter material particle. When placed in water, it will continuously purify the ammonia nitrogen and nitrite. However, there is a problem with the filter material particles, that is, they need constant movement to ensure the activity of their main components. Once they are accumulated for a long time without movement, they will lose their activity. In current home aquariums and breeding tanks, filter material particles are generally placed in a mesh container and put into water. The airflow generated by oxygenation and the water flow generated by the circulating water flow drive the filter material particles to have a certain movement effect. The degree of movement is low, and the activity retention period of the filter material particles is short. Utility Model Content

[0027] Reference Figures 1 to 5 , a fluidized bed aquarium filter, comprising:

[0028] The filter housing 10 has a filter cavity 11 disposed therein, the filter cavity 11 is provided with a flow disturbance hole 12 , the flow disturbance hole 12 is connected to a water pump 30 or an air pump, and the inner wall of the filter housing 10 is provided with a flow exchange water hole 13 .

[0029] In this solution, the flow disturbance holes 12 are preferably arranged at the bottom of the filter cavity 11 , and the flow exchange holes 13 are arranged on the side wall of the filter housing 10 .

[0030] When in use, the filter material particles are placed in the filter chamber 11, and the sewage filter is placed in a water tank such as an aquarium. The water pump 30 or the air pump continuously passes water or air into the filter chamber 11, thereby causing the water flow in the filter chamber 11 to be continuously disturbed. The density ratio of the filter material particles to water is close to 1, so the process of water flow disturbance will drive the filter material particles to continuously roll, thereby ensuring their activity. The water in the filter chamber 11 is continuously exchanged with the water in the aquarium or breeding tank through the exchange water holes 13 on the side wall of the filter shell 10, thereby continuously purifying the water in the water tank.

[0031] In this solution, since there are certain solid impurities in the water, it is preferred that a dirt box 20 is provided at the top of the filter chamber 11, a dirt hole 21 communicating with the filter chamber 11 is provided at the bottom of the dirt box 20, and a dirt surrounding pipe 22 surrounding the dirt hole 21 is provided in the dirt box 20. When installing, the entire sewage filter is placed in a water tank such as an aquarium, so that the water in the water tank submerges the dirt hole 21 and is slightly lower than the top of the dirt surrounding pipe 22. When the water pump 30 or the air pump is working, the water flow in the filter chamber 11 is driven to flow continuously, and the water surface at the top of the filter chamber 11 is continuously fluctuated. At the same time, the water flow process will wrap the dirt and flow upward and flow along the dirt hole 21 to the dirt box 20. Since the water surface is constantly fluctuating, part of the dirt will pass through the dirt surrounding pipe 22 under the action of the water surface fluctuation and fall into the dirt box 20, so that it is collected by the dirt box 20, and then a certain filtering effect is achieved.

[0032] In this solution, the flow disturbance hole 12 is preferably connected to an air pump. In the case of connecting to the air pump, in order to make the disturbance process of the water flow in the filter chamber 11 more intense, it is preferably provided with a water inlet hole connected to the bottom of the filter chamber 11 at the bottom of the filter housing 10. Under this structure, the air pump continuously blows air into the filter chamber 11 from the bottom, thereby forming bubbles moving upward in the filter chamber 11. The bubbles continuously drive the water in the filter chamber 11 to produce a turbulent flow, thereby driving the filter material particles to move. At the same time, the ability of the bubbles to entrain impurities is stronger, so it is easier to carry solid impurities into the dirt box 20. At the same time, when the bubbles flow to the water surface in the dirt box 20, since the upward movement is directly in contact with the air, the bubbles will explode on the water surface, thereby making the water surface fluctuation more intense and more likely to push the impurities over the dirt surrounding pipe 22, so that they fall into the outside of the dirt surrounding pipe 22 and are collected.

[0033] In this solution, the top of the waste surrounding pipe 22 is preferably covered with a gas-liquid separation nozzle, and the edge of the gas-liquid separation nozzle is provided with a gas-liquid separation gap, through which the bubbles can be further punctured quickly, so that the impurities entrained by the bubbles pass along the gas-liquid separation gap to the outside of the waste surrounding pipe 22 and are collected. In this solution, the gas-liquid separation gap is preferably in the shape of a "I" or a "Y".

[0034] In this solution, it is preferred that a plurality of dirt gaps are provided on the dirt surrounding tube 22. When the dirt gaps are provided, the impurities driven by the explosion of bubbles can fall into the dirt box 20 as long as they pass through the dirt gaps.

[0035] Of course, the flow disturbance hole 12 is connected to the water pump 30, and the water pump 30 is connected to the water inlet pipe 31. The water pump 30 is used to pump water into the filter chamber 11, thereby driving the water in the filter chamber 11 to cause flow disturbance, and at the same time, it has a water inlet effect. When installing, it is preferred that the water inlet pipe 31 is also placed in the water tank. Combined with the above-mentioned effect of introducing bubbles into the filter chamber 11 to assist in filtering solid impurities, it is preferred that the water inlet pipe 31 is connected to an air supply pipe 50 extending to the top of the filter housing 10, and the end of the air supply pipe 50 is provided with a venturi tube 51 connected to the water inlet pipe 31, so that when the water pump 30 passes water into the filter chamber 11, due to the pressure difference generated by the flow velocity of the water flow, and in conjunction with the structure of the venturi tube 51, air can be directly sucked into the water inlet pipe 31 along the air supply pipe 50, thereby inputting a mixture of water and air into the filter chamber 11.

[0036] In this solution, in order to make the flow of water in the filter chamber 11 more regular, it is preferred that a central partition 14 is provided in the filter chamber 11 to divide the filter chamber 11 into a ring shape, and the flow disturbance hole 12 is located on one side of the central partition 14. With this structure, since the flow disturbance hole 12 is located on one side of the central partition 14, the air pump or water pump 30 will encourage the water flow to flow upward along one side of the central partition 14 first, and then flow toward the other side of the central partition 14 after touching the top surface of the filter chamber 11, thereby forming a vortex, and driving the filter material particles to circulate and roll in the filter chamber 11, so that the movement effect of the filter material particles is better.

[0037] In this solution, the inner wall on the right side of the filter chamber 11 preferably includes a vertical wall 15 at the upper end and an inclined wall 16 located at the lower end of the vertical wall 15 and inclined toward the spoiler hole 12. The vertical wall 15 and the inclined wall 16 are both provided with the exchange water hole 13. The central partition 14 is located between the inclined wall 16 and the spoiler hole 12. The filter material particles are automatically moved toward the spoiler hole 12 along the inclined wall 16 when rolling downward along the right side of the filter chamber 11 through the inclined wall 16, so that they are driven to move upward along the left side of the filter chamber 11 under the movement of the spoiler hole 12. The setting of the inclined wall 16 prevents the filter material particles from accumulating at the dead point without moving. At the same time, since the inclined wall 16 is directly opposite to the path of the water flow backflow, the water flow purified by the filter material particles is more likely to flow along the exchange water hole 13 on the inclined wall 16 to the water tank outside the filter housing 10.

[0038] In the present solution, it is further optimized that the bottom surface of the waste box 20 preferably includes a top surface 23 in the middle and guide surfaces 24 located on both sides of the top surface 23 and inclined downward, and the waste hole 21 is arranged on the top surface 23, so as to better drive the water circulation through the guide surface 24 and the top surface 23.

[0039] For further optimization, since the water level in the water tank is not fixed to a specific height, and the dirt box 20 has certain requirements for the water level height, it is preferred that the upper end of the filter chamber 11 extends to the top of the filter housing 10, and the dirt box 20 is movably inserted into the filter chamber 11 along the top of the filter housing 10. The surface of the filter housing 10 is screwed with a positioning bolt 42 whose end extends into the filter chamber 11. The positioning bolt 42 is used to abut against the surface of the dirt box 20 and fix the dirt box 20. Through this structure, the relative position of the dirt box 20 and the water surface can be adjusted by the positioning bolt 42, thereby facilitating the filtering of impurities in the water in the water tank through the dirt box 20.

[0040] On this basis, in order to expand the range of height adjustment, it is preferred that a hook 60 is provided on the back of the filter housing 10, and a strip hole is provided on the hook 60. A locking bolt is screwed on the back of the filter housing 10, and the locking bolt is inserted in the strip hole. During installation, the entire filter housing 10 is hung in a water tank such as an aquarium through the hook 60, and the relative position of the hook 60 and the filter housing 10 is adjusted through the strip hole, thereby adjusting the water surface height in the filter chamber 11.

[0041] In this solution, it is preferred that an outer shell 40 is further included, wherein an upper opening accommodating cavity is provided inside the outer shell 40, wherein the filter housing 10 is inserted into the accommodating cavity, and a connecting water hole 41 communicating with the accommodating cavity is provided on the surface of the outer shell 40. It is preferred that the exchange water hole 13 on the inclined wall 16 is directly opposite to the connecting water hole 41, and on the basis of providing the outer shell 40, it is preferred that the positioning bolt 42 is screwed on the outer shell 40, and the hook 60 is also provided on the back of the outer shell 40, and the locking bolt is also screwed on the back of the outer shell 40.

[0042] In this solution, in order to facilitate installation and cleaning, the spoiler hole 12 is preferably provided on a spoiler plate, and the spoiler plate is detachably fixed on the inner wall of the filter cavity 11, so as to facilitate disassembly for cleaning or replacement.

[0043] When an air pump is used, the spoiler holes 12 are preferably air diffusion holes arranged on an air diffusion plate, and the air diffusion plate is fixedly mounted on the inner wall of the filter chamber 11, so as to achieve a better effect of dispersing the gas.

[0044] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
