Description

Technical Field

[0001] The utility model relates to an aquaculture tool, in particular to a container filter. Background Art

[0002] Filters are commonly used water filtration tools in aquarium farming. There are many structures and shapes of filters. Among them, container-type filters, which are used in combination of multiple filters stacked up and down, are one of the common filters. The filter material is placed in the filter box and assembled together up and down. Water enters the top filter box, and then the water is filtered through the filter materials in each layer of the filter box and enters the bottom water storage tank, and is discharged into the aquarium from the water storage tank. However, in the current filter, the water in the upper filter box is easily biased from the high side to the bottom side along the bottom surface of the upper filter box when it flows into the lower layer, resulting in uneven water flow into the lower filter box, affecting filtration. At the same time, when setting the inlet and outlet pipes of the current filter box and the water storage tank, water inlets are mostly opened on the filter box and the water storage tank body, and then the water pipes are passed through the water inlets, and then the water distribution pipes or connecting pipes, valves, etc. are respectively connected to the inner and outer ends of the water pipes. Since the walls of the filter box and the water storage tank are relatively thin, the water pipes passing through the water inlets are unstable and leak. Therefore, connecting nuts for fixing and sealing the water pipes need to be respectively provided on both sides of the water inlet. The water pipes are fixedly installed and prevented from leaking by tightening the connecting nuts. Sometimes the overflow prevention pipe in the filter box is also installed on the bottom wall of the filter box in this way. The above-mentioned installation method of the water pipe on the filter box not only uses a large number of pipe fittings, but also the installation and connection of the pipe fittings are cumbersome, and there is a risk of pipe fittings shaking and water tank leakage.

It should be noted that, in the accompanying drawings, the same reference numerals are given to components having substantially the same structure and function, and in order to make the description more concise, redundant descriptions of substantially the same components are omitted.

[0022] like Figure 1-4As shown, the container filter comprises an upper filter box 1 and a lower water storage tank 2 stacked up and down. The inner side of the bottom periphery of the upper filter box 1 can be provided with a snap ring edge 4 that protrudes downward and is snap-fitted with the top box opening of the lower water storage tank 2. The bottom of the upper filter box 1 is snap-fitted with the top of the lower water storage tank 2 through the snap ring edge 4. If a filter box is stacked on the lower side of the upper filter box 1, the snap ring edge 4 is also used for snapping, and a box cover 22 can be provided at the top box opening of the upper filter box 1 for covering; a plurality of drain holes 5 are provided at the bottom of the upper filter box 1, and a water inlet pipe 6 integrally formed with the box body is provided on one side of the upper filter box 1, and an outlet pipe integrally formed with the box body is provided on one side of the lower water storage tank 2. Water pipe 9, the water inlet pipe 6 connects the inner and outer sides of the upper filter box 1, and the water outlet pipe 9 connects the inner and outer sides of the lower water storage tank 2; one side of the upper filter box 1 is provided with an anti-overflow pipe 13 integrally formed with the box body, the upper end of the anti-overflow pipe 13 is located at the upper part of the upper filter box 1 and the lower end is located at the outer side of the bottom of the upper filter box 1, and the anti-overflow pipe 13 is integrally formed on one side of the upper filter box 1, which avoids the trouble of drilling holes at the bottom of the upper filter box 1 to install the anti-overflow pipe 13 when preventing water blocking in the box, or the defect of specially setting an overflow area on one side of the upper filter box 1, which leads to a smaller filter area in the upper filter box 1. The water inlet pipe 6 is located at the upper part of the rear side of the upper filter box 1, and the water outlet pipe 9 is located at the lower part of the rear side of the lower water storage tank 2, which is not only convenient for the arrangement of filter materials and pipes, but also improves the beauty of the filter. The upper part of the left or right side of the upper filter box 1 is also provided with a water inlet pipe 6 to meet the demand for water entering the filter from the side. When in use, filter materials such as filter cotton are placed in the upper filter box 1, and the water inlet pipe 7 passes through the water inlet pipe 6 and extends into the upper side of the filter material in the upper filter box 1. The outer circumference of the water inlet pipe 7 and the inner circumference of the water inlet pipe 6 are closely matched to prevent water leakage. In order to evenly distribute water on the filter material, the water distribution pipe system 8 can be connected to the inner end of the water inlet pipe 7, and the outer end of the water inlet pipe 7 is connected to the water inlet system such as a pump. The water inlet pipe 6 supports and fixes the water inlet pipe 7, ensuring the stability of the entire water inlet pipe 7. Similarly, the water outlet pipe 10 passes through the water outlet pipe 9 and extends into the lower part of the lower water storage tank 2. The outer circumference of the water outlet pipe 10 and the inner circumference of the water outlet pipe 9 are closely matched to prevent water leakage. The outer end of the water outlet pipe 10 is connected to the water outlet pipe system such as the control valve 11, and the water outlet pipe 9 supports and fixes the water outlet pipe 10, ensuring the stability of the entire water outlet pipe system. In addition, the water inlet pipe 6 can be extended from the inner and outer sides of the upper filter box 1, and the water outlet pipe 9 can be extended from the inner and outer sides of the lower water storage tank 2, so that the water inlet pipe 7 can be set on the outer end of the water inlet pipe 6, the water distribution pipe system 8 can be plugged into the inner end of the water inlet pipe 6, and the water outlet pipe 10 can be set on the outer end of the water outlet pipe 9, which is more convenient for connecting pipes and further prevents water leakage. The water inlet pipe 6 on the upper filter box 1 of the utility model can be set one or two, or even more, according to the filtering requirements and the size of the box, and the water outlet pipe 9 on the lower water storage tank 2 can be set one or two, or even more, according to the filtering requirements and the size of the box.

[0023] like Figure 2-3 As shown, the bottom of the upper filter box 1 is provided with a supporting device for supporting the filter material, and the outer side of the bottom of the upper filter box 1 is provided with a lower ring tube 14 protruding downwards on the peripheral side of the opening of the water hole 5.

When used in this way, a water inlet pipe 7 can be arranged above the upper filter box 1, and water flows to the fine filter mesh 19 for preliminary filtration, while larger impurities are flushed into the dirt collecting box 16 for collection and cleaning. The dirt collecting box 16 can be provided with a pin 21 inserted into the pipe opening of the upper end of the anti-overflow pipe 13 extending from the bottom, which is convenient for the installation of the dirt collecting box 16, and a gap is left between the pin 21 and the pipe opening of the upper end of the anti-overflow pipe 13, so that water can flow out through the anti-overflow pipe 13 when the filter material in the box is blocked and blocked.

[0026] like Figure 5 As shown, when in use, an upper filter box 1, an intermediate filter box 3 and a lower water storage tank 2 are stacked up and down to form a container filter. The upper filter box 1 and the intermediate filter box 3 contain filter materials. The upper filter box 1 is equipped with a water inlet pipe 7 through a water inlet pipe 6. The inner end of the water inlet pipe 7 is connected to a water distribution pipe system 8. Two water outlet pipes 10 are respectively installed on the lower water storage tank 2 through two water outlet pipes 9. The outer ends of the two water outlet pipes 10 are respectively connected to control valves 11. The water in the aquarium or other water sources flows into the upper filter box 1 evenly through the water inlet pipe 7 and the water distribution pipe system 8 through a pump. After being filtered by the filter material in the upper filter box 1, it flows evenly into the intermediate filter box 3 through the lower water hole 5 for re-filtration, and then flows into the water storage tank. The filtered water in the water storage tank can be controlled by the control valve 11 to enter an aquarium or different aquariums to achieve water quality filtration. The inner ends of the two water outlet pipes 10 located in the lower water storage tank 2 are respectively connected to the T-shaped pipes 12, so that the water inlets of the two water outlet pipes 10 are spaced far apart from each other to facilitate water outlet.
