Description

Technical Field

[0001] This utility model relates to a vertical filtration system and belongs to the field of aquarium filtration technology. Background Technology

[0002] When keeping fish in aquariums, fish feces, leftover fish food, and other waste will remain in the aquarium, easily polluting the water. Therefore, filtration devices are usually used to filter the water in the aquarium to remove the waste.

[0003] Current aquarium filtration devices, such as those disclosed in Chinese invention patent application CN110024738A, consist of multiple filter media boxes arranged from top to bottom within a filter media box holder. A cover is provided at the top of the holder. During use, water from the aquarium is introduced through the bottom of the holder, flows upwards within the holder, and exits from the top. However, this design makes cleaning the filter media boxes inconvenient, as they are stacked vertically, requiring the removal of each box and overall cleaning process. Furthermore, since the water flows upwards, a water pump is needed as the power source to maintain the water flow.

[0004] Chinese utility model patent with authorization announcement number CN221191822U discloses a biomimetic water purification system with a fish scale structure. The system includes a filter mechanism, which includes a filling box with a filling space inside. The filling material is placed in the filling space and arranged in a fish scale structure. The filling box is sealed inside the filter box by a top cover. The top cover needs to be removed before it can be disassembled, so it is still relatively inconvenient to clean. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical filtration system that solves the technical defect in existing filtration systems where it is inconvenient to disassemble the filter screen, thus making it inconvenient to clean the filter screen.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a vertical filtration system, including a shell and multiple filtration units. The shell is a cuboid structure with an open top. One end is the water inlet, which is used to connect to the main tank for raising fish when in use. Water from the main tank enters the shell from the water inlet. The other end is the water outlet, which is used to connect to the clear water chamber when in use. Multiple filtration units are arranged at intervals along the length of the shell. The filtration units are vertical inside the shell and can be detachably installed from the shell. The pore size of the filter holes on the filtration units decreases sequentially from the water inlet to the water outlet. Water containing dirt in the shell is filtered sequentially by multiple filtration units and then enters the clear water chamber from the water outlet. The housing of this utility model has a top-opening structure, and multiple filter units are installed independently. When disassembling the filter unit, simply lift the filter unit upwards to pull it out of the housing, thus facilitating the cleaning of the filter unit. After cleaning each independent cleaning unit, the cleaning unit can be installed back into the housing. Because the filter units in this utility model are easy to install and disassemble, the overall cleaning of this utility model is also more convenient. In this utility model, the pore size of the filter holes on the filter unit gradually decreases, so different sizes of particles in the water can be filtered out separately. The method of filtering out large particles first and then small particles effectively avoids large particles clogging the filter units with smaller pores.

[0007] As a further improvement of this utility model, the filter unit includes two identical clamping plates on the left and right sides and a filter screen. Multiple through holes are provided on the clamping plates, and the two clamping plates are located on both sides of the filter screen, clamping the filter screen between the two clamping plates. Vertical slots are provided on the two opposing inner walls of the housing, and the two ends of the filter unit are positioned within these slots, allowing the filter unit to be pushed and pulled vertically. This utility model uses two clamping plates to clamp the filter screen from both sides, facilitating the fixation of the filter screen and effectively preventing deformation of the filter screen due to water flow.

[0008] As a further improvement of this invention, vertical baffles are fixed on two opposing inner walls inside the housing, forming a slot between the two baffles for inserting the filter unit. This invention simplifies the fabrication of the slot by attaching the baffles inside the housing.

[0009] As a further improvement of this utility model, multiple fasteners are provided on the two clamping plates. These fasteners are positioned to avoid the through holes and pass through the filter screen, serving to secure the filter screen and the two clamping plates. This utility model, by providing these fasteners, facilitates the fixing of the filter screen to the clamping plates.

[0010] As a further improvement of this utility model, it also includes a drain pipe, which is located at the bottom of the housing. Each filter unit has a drain pipe on both sides, and a drain valve is installed on the drain pipe. Opening the drain valve allows for the discharge of dirt generated during filtration inside the housing. The drain pipe in this utility model facilitates the discharge of dirt generated by filtration and sedimentation at the bottom of the housing, making it easier to clean this utility model.

[0011] As a further improvement of this utility model, the two sides of the housing used to fix the filter unit extend downward to form support protrusions, and a horizontal channel is formed between the support protrusions. One end of the drain pipe is connected to the bottom of the housing within the horizontal channel, and the other end passes through one of the support protrusions and extends out of the horizontal channel. The drain valve is located outside the horizontal channel. This utility model sets support protrusions at the bottom of the housing to form a horizontal channel, which facilitates the installation of the drain pipe.

[0012] As a further improvement of this utility model, it also includes a main sewage pipe, which is closed at one end and open at the other. All sewage pipes are connected to the main sewage pipe, and the sewage discharged from the sewage pipes is collected in the main sewage pipe and discharged from the open end of the main sewage pipe. The main sewage pipe provided in this utility model facilitates the centralized collection and discharge of sewage discharged from the sewage pipes.

[0013] As a further improvement of this utility model, it also includes multiple overflow pipes, with one overflow pipe on each side of each filter unit. The top end of the overflow pipe is connected to the upper part of the housing, and the bottom end of the overflow pipe is connected to the main drain pipe. When the filter unit is clogged, the water in the housing flows into the main drain pipe from the overflow pipe and is discharged. By setting the overflow pipes, this utility model allows water to be discharged from the housing when the water level inside the housing rises due to clogging of the filter unit, preventing water from flowing out from the top of the housing.

[0014] As a further improvement of this utility model, a fixing plate is provided on the top of the housing at the water inlet end. A water inlet pipe is provided on the fixing plate, passing through its upper and lower surfaces and extending into the lower part of the housing. The water inlet pipe is connected to the main cylinder, and water in the main cylinder flows into the housing through the water inlet pipe. This utility model, by providing a fixing plate, facilitates the fixing of the water inlet pipe during use.

[0015] As a further improvement of this utility model, it also includes a water outlet pipe, one end of which is connected to the lower part of the water outlet end of the shell. The filtered clean water inside the shell flows into the clean water chamber through the water outlet pipe. This utility model is equipped with a water outlet pipe, and the water outlet pipe is connected to the lower part of the shell, which facilitates the discharge of filtered water.

[0016] As a further improvement of this utility model, it also includes an overflow trough and an overflow pipe. The overflow trough is fixed to the upper part of the housing. Each filter unit on the housing has an overflow hole on both sides, and the overflow hole connects the overflow trough and the housing. The top end of the overflow pipe is connected to the bottom of the overflow trough, and the bottom end of the overflow pipe is connected to the main sewage pipe. By setting an overflow trough, this utility model can reduce the number of overflow pipes by requiring only one overflow pipe to connect the overflow trough and the main sewage pipe.

[0017] As a further improvement of this utility model, a baffle is also included, which is fixed inside the water inlet end of the housing and located between the water inlet pipe and the drain pipe at the water inlet end. This utility model provides a baffle to buffer the water entering the housing and prevent the water from impacting the filter unit.

[0018] In summary, the beneficial effects of this utility model are: this utility model facilitates the cleaning of the filter unit and makes it easy to collect and discharge the cleaned dirt; when the filter unit becomes clogged, no water will overflow from the top of the housing.

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Example 1

[0029] like Figures 1 to 5 The vertical filtration system shown includes a housing 1 and multiple independent filter units 2. The housing 1 is a cuboid structure with an open top, and includes a front side plate 103, a rear side plate 104, a left side plate 105, a right side plate 106, and a bottom plate 107. The front side plate 103 and the rear side plate 104 are arranged in parallel. The front and rear ends of the left side plate 105 are respectively bonded and fixed to the left ends of the front side plate 103 and the rear side plate 104. The front and rear ends of the right side plate 106 are respectively bonded and fixed to the right ends of the front side plate 103 and the rear side plate 104. The four sides of the bottom plate 107 are respectively bonded and fixed to the front side plate 103 and the rear side plate 104. The bottom or lower part of the side plate 103, rear side plate 104, left side plate 105 and right side plate 106 are glued and fixed. In this embodiment, the front side plate 103, rear side plate 104, left side plate 105, right side plate 106 and bottom plate 107 can be made of transparent material, such as glass. The right end of the shell 1 is the water inlet 101, which is used to connect to the main tank for raising fish when in use. Water containing dirt in the main tank enters the shell 1 from the water inlet 101. The left end of the shell 1 is the water outlet 102, which is used to connect to the clean water tank when in use.

[0030] like Figures 1 to 6 As shown, multiple filter units 2 are evenly spaced along the length of the housing 1 within the housing 1, dividing the housing 1 into a transition cavity 108 that is one more than the number of filter units 2. The filter units 2 are vertically arranged within the housing 1 and are detachably installed from the housing 1. All filter units 2 are parallel, and the diameter of the filter holes 201 on the filter units 2 decreases sequentially from the water inlet 101 side to the water outlet 102 side. Water containing impurities in the housing 1 is filtered sequentially by multiple filter units 2, and the resulting clean water enters the clean water chamber from the water outlet 102. In use, the clean water in the clean water chamber is then pumped into the main tank by a water pump for raising fish. In this embodiment, "vertical" refers to the vertical arrangement of the filter units 2.

[0031] like Figure 6As shown, the filter unit 2 includes a filter screen 204 and two identical clamping plates 202 on the left and right sides. Multiple through holes 203 are formed on the clamping plates 202, penetrating both sides. The through holes 203 are rectangular holes, with their length and width significantly larger than the diameter of the filter holes 201 on the filter unit 2. The two clamping plates 202 are located on both sides of the filter screen 204, clamping the filter screen 204 between them to fix it in place. The filter holes 201 are holes on the filter screen 204. Vertical slots are provided on the two opposing inner walls of the housing 1. In this embodiment, the slots are located on the opposite side of the front side plate 103 and the rear side plate 104. On the surface, both ends of the filter unit 2 are set in the slots, and the filter unit 2 can be pushed and pulled in the vertical direction to install the filter unit 2 in the housing 1 or to pull the filter unit 2 out of the housing 1. In this embodiment, vertical baffles 205 are fixed on two opposing inner walls inside the housing 1. The cross-sectional shape of the baffles 205 is rectangular. The baffles 205 are fixed to the opposing surfaces of the front side plate 103 and the rear side plate 104 by adhesive. A slot for inserting the filter unit 2 is formed between the two baffles 205. When the filter unit 2 is inserted into the slot and pushed downward until the bottom end of the filter unit 2 contacts the bottom plate 107, the filter unit 2 is installed in place.

[0032] In this embodiment, multiple fasteners (not shown in the figure) are provided on the two clamping plates 202. The fasteners are set to avoid the through hole 203 and pass through the filter screen 204 to fix the filter screen 204 and the two clamping plates 202. In this embodiment, the fasteners can be bolts and nuts made of plastic material. The bolts pass through the filter screen 204 and the two clamping plates 202, and the nuts cooperate with the bolts to fix the filter screen 204 and the two clamping plates 202. The fasteners can also be rivets.

[0033] like Figure 4 and Figure 5 As shown, in order to facilitate the discharge of dirt settled at the bottom of the housing 1 after a period of use, this embodiment is provided with a drain pipe 3. The drain pipe 3 is located at the bottom of the housing 1, and drain pipes 3 are provided on both sides of each filter unit 2. That is, in this embodiment, each transition cavity 108 is connected to a drain pipe 3 at the bottom. One end of the drain pipe 3 passes through the bottom plate 107 from the bottom upward, so that the drain pipe 3 communicates with the transition cavity 108. The drain pipe 3 is fixed to the bottom plate 107 by adhesive. A drain valve 4 is provided on the drain pipe 3. Opening the drain valve 4 is used to discharge the dirt generated by filtration in the housing 1. Closing the drain valve 4 can ensure that the water in the housing 1 will not be discharged outside the housing 1 through the drain pipe 3 under normal use.

[0034] like Figures 2 to 5As shown, in this embodiment, the housing 1 is used to fix the two sides of the filter unit 2, that is, the bottom of the front side plate 103 and the rear side plate 104 extends downward to form a support protrusion 206. A horizontal channel 207 is formed between the two support protrusions 206. One end of the drain pipe 3 bends upward in the horizontal channel 207 and communicates with the bottom of the housing 1. The other end of the drain pipe 3 passes through one of the support protrusions 206 and extends out of the horizontal channel 207. The drain valve 4 is set outside the horizontal channel 207. In this embodiment, a main drain pipe 5 is set outside the horizontal channel 207. One end of the main drain pipe 5 is closed and the other end is open. All drain pipes 3 are connected to the main drain pipe 5. The sewage discharged from the drain pipes 3 is collected in the main drain pipe 5 and discharged from the open end of the main drain pipe 5, which facilitates the collection and treatment of the sewage discharged in this embodiment.

[0035] like Figure 3 and Figure 4 As shown, in order to prevent water in the transition chamber 108 from overflowing from the top of the housing 1 when the filter unit 2 is clogged, this embodiment is provided with multiple overflow pipes 6. Each filter unit 2 has one overflow pipe 6 on each side, that is, each transition chamber 108 is provided with one overflow pipe 6. The top end of the overflow pipe 6 is connected to the upper part of the housing 1, and the bottom end of the overflow pipe 6 is connected to the main drain pipe 5. When the filter unit 2 is clogged, the water in the transition chamber 108 on the side of the filter unit 2 near the water inlet 101 will flow from the overflow pipe 6 into the main drain pipe 5 and be discharged, instead of flowing out from the top of the housing 1.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, to facilitate the entry of water from the main cylinder into this embodiment, a fixing plate 7 is provided on the top of the water inlet 101 on the housing 1. The fixing plate 7 is glued and fixed to the top of the front side plate 103 and the rear side plate 104. A circular hole (not shown in the figure) is provided on the fixing plate 7, penetrating its upper and lower surfaces. A water inlet pipe 8 is provided in the circular hole, extending into the lower part of the housing 1. The water inlet pipe 8 is fixed to the fixing plate 7 by adhesive. The water inlet pipe 8 is connected to the main cylinder, and the water containing dirt in the main cylinder flows into the housing 1 through the water inlet pipe 8. To facilitate the entry of filtered clean water into the clean water chamber, this embodiment is provided with a water outlet pipe 9. One end of the water outlet pipe 9 is connected to the lower part of the water outlet 102 of the housing 1. In this embodiment, the water outlet pipe 9 is preferably connected to the housing 1 from the lower part of the left side plate 105. The filtered clean water in the housing 1 flows into the clean water chamber through the water outlet pipe 9. The clean water in the clean water chamber is then pumped into the main cylinder by a water pump, realizing the recycling of the filtered water in the main cylinder.

[0037] In this embodiment, the main cylinder is positioned above the main cylinder, while the clear water chamber is positioned below it. The end of the inlet pipe 8 furthest from the housing 1 is connected to the bottom of the main cylinder. Thus, the water containing impurities in the main cylinder can flow directly into the housing 1 under the influence of gravity. The water containing impurities in the housing 1 is filtered sequentially by multiple filter units 2. Since the filter holes 201 on the filter units 2 decrease in size sequentially, this embodiment first filters out larger particles and then filters out smaller particles in sequence. The water obtained at the outlet 102 is clear water. The clear water flows directly into the clear water chamber under the influence of gravity. The clear water in the clear water chamber is pumped back into the main cylinder by a water pump, realizing the recycling of water.

[0038] In this embodiment, when the filter unit 2 needs to be cleaned, the filter unit 2 is pulled upward from the top of the housing 1 to remove it from the housing 1. After rinsing with clean water, the filter unit is inserted into the slot from the top of the housing 1 and pushed downward until the bottom of the filter unit 2 touches the bottom plate 107. After a period of use, the drain valve 4 can be opened to allow the dirt settled at the bottom of the transition chamber 108 to be discharged through the drain pipe 3 and the main drain pipe 5, and then the drain valve 4 can be closed. Example 2

[0039] This embodiment is a further improvement on embodiment 1. Compared to embodiment 1, to prevent water in the transition chamber 108 from overflowing from the top of the housing 1 when the filter unit 2 becomes clogged, as shown below... Figure 7 As shown, this embodiment includes an overflow trough 10 and an overflow pipe 6. The overflow trough 10 is bonded and fixed to the upper part of the rear side plate 104 of the housing 1. The overflow trough 10 has a top-opening structure. An overflow hole 11 is provided on each side of each filter unit 2 on the rear side plate 104 of the housing 1. The overflow hole 11 connects the overflow trough 10 and the housing 1. The top end of the overflow pipe 6 is connected to the bottom of the overflow trough 10, and the bottom end of the overflow pipe 6 is connected to the main drain pipe 5.

[0040] like Figure 8 As shown, this embodiment includes a baffle 12, which is fixed inside the water inlet end 101 of the housing. The baffle 12 is located between the water inlet pipe 8 and the drain pipe 3 of the water inlet end 101. The front and rear ends of the baffle 12 are respectively bonded and fixed to the front side plate 103 and the rear side plate 104, and the bottom end of the baffle 12 is bonded and fixed to the bottom plate 107. The height of the baffle 12 can be set to be slightly less than half of the filter unit 2 to buffer the water entering the housing 1 from the water inlet pipe 8 and reduce the impact on the filter unit 2. The structure of the remaining parts in this embodiment is the same as that in Embodiment 1. For details, please refer to Embodiment 1, and it will not be described again in this embodiment.

[0041] Unless otherwise specified in the above description, all parts are existing technology or can be implemented using existing technology. Furthermore, the specific embodiments described in this utility model are merely preferred embodiments of the invention and are not intended to limit the scope of this utility model. That is, all equivalent changes and modifications made within the scope of this utility model patent should be considered within the technical scope of this utility model.
