Description

Technical Field

[0001] This application relates to aquarium filtration equipment technology, and more particularly to a dual-drum filtration device. Background Technology

[0002] A fish tank mainly consists of a tank body and a cabinet. The tank body is supported on the cabinet. Excrement, food residue, and other impurities inside the tank are usually filtered by the filter material of the filter device to ensure the water quality inside the tank.

[0003] Traditional aquariums typically use a single-drum filtration system. This system consists of a single rotating drum filter. Water flows through the filter and clear water is discharged, but impurities accumulate and require manual or periodic rinsing. However, the filtration area of ​​a single drum of the same size is limited, resulting in a small water throughput per unit time. Furthermore, the need for regular cleaning of the filter screen makes the process cumbersome and unsuitable for high-density aquariums. Summary of the Invention

[0004] This application provides a dual-drum filter device to solve the technical problem in related technologies that dual-drum filter devices require periodic disassembly of the filter material to clean impurities.

[0005] On one hand, this application provides a dual-drum filtration device, comprising:

[0006] The housing frame has an inlet and a clean water outlet for connection to the equipment to be filtered;

[0007] Two rotating drum filter support frames are located in the housing frame and are covered with a filter layer. One end of each rotating drum filter support frame is connected to the water inlet, and the other end extends out of the housing frame to form a drain pipe. The clean water outlet is located below the filter layer.

[0008] The backwash assembly includes a backwash water pipe connected to an external water source, the backwash water pipe having a plurality of backwash nozzles connected in parallel, the backwash nozzles being disposed toward the filter layer, the backwash nozzles being configured to flush impurities adhering to the filter layer so that the impurities are discharged along the drain pipe out of the housing frame.

[0009] In some possible implementations, the two drum filter support frames are arranged side by side, and the two drum filter support frames are driven to rotate by a common drive component.

[0010] In some possible implementations, the interior of the housing frame is divided by a partition to form an inlet area and an overflow area. The drum filter screen is supported in the overflow area. The inlet is located on the side wall corresponding to the inlet area, and the clean water outlet is located on the bottom plate of the overflow area.

[0011] In some possible implementations, flange rings are respectively fitted on the same side of the two drum filter support frames, and a drive motor is fixed on the housing frame. The output end of the drive motor is connected to the two drum filter support frames in a transmission engagement.

[0012] In some possible implementations, the backwash assembly further includes a backwash water pump, the pumping end of which is connected to the inlet area, and the output end of which is connected to the backwash water pipe.

[0013] In some possible implementations, a water level float valve is also included, which is located on the side wall of the water inlet area, and the height of the water level float valve is higher than the height of the water inlet.

[0014] In some possible implementations, a plurality of the backwash nozzles are arranged at intervals along the length of the drum filter support frame, and the nozzles of the backwash nozzles are fan-shaped nozzles.

[0015] In some possible implementations, the water inlet is a mesh opening located at the bottom of the housing frame.

[0016] In some possible implementations, an impurity collection box is fixed to the housing frame, the impurity collection box is located in the drum filter support frame, and the opening of the impurity collection box is oriented toward the backwash nozzle;

[0017] The impurity collection box is connected to the drain pipe, and the backwash nozzle washes the impurities on the filter layer so that the impurities are sent into the drain pipe through the impurity collection box.

[0018] In some possible implementations, the filter layer is a mesh screen.

[0019] (1) The dual-drum filter device provided in this application uses parallel backwash nozzles to directly impact the filter layer with reverse water flow. Impurities can be discharged through the drain pipe without disassembling the filter layer, avoiding the cumbersome operation of frequently removing filter media required by traditional filter devices. This helps to extend the disassembly period and reduce the frequency of disassembly and maintenance.

[0020] (2) The dual-drum filter device provided in this application drives two drum filter support frames to rotate through a driving component, so that the backwash nozzle can clean the filter layer at different angles alternately, which is beneficial to improve cleaning efficiency and enhance the flushing effect. In addition, the two drum filter support frames can provide emergency backup guarantee. When the filter layer on a single drum filter support frame is blocked, the other drum filter support frame can still be kept running, avoiding the risk of system shutdown caused by single frame failure.

[0021] (3) The dual-drum filter device provided in this application is designed to separate the overflow zone and the inlet zone. The water flow entering the inlet zone can initially settle and flocculate, reducing the filtration load of the drum filter support frame in the overflow zone. At the same time, the inlet zone is also convenient to observe the height of the filtered water, thereby preventing the filter layer from accumulating too many impurities and failing to filter normally.

[0022] (4) The height of the float valve of the water level in the dual-drum filter device provided in this application is higher than that of the inlet, which can prevent water from flowing back into the cylinder due to excessive blockage of impurities in the overflow area, and ensure the normal operation of the dual-drum filter device.

[0023] (5) The dual-drum filter device provided in this application has a clear water inlet set as a mesh inlet, which can form a double-layer filtration effect with the filter layer of the drum filter support frame, preventing impurities from leaking out and directly entering the cylinder.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

[0036] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0038] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0039] As described in the background section, an aquarium mainly consists of a tank body and a cabinet. The tank body is supported on the cabinet, and the waste, food residue, and other impurities inside the tank body are usually filtered by the filter material of the filter device to ensure the water quality inside the tank body.

[0040] However, as the filtration device filters and purifies water containing particulate matter, a lot of dirt will accumulate on the filter material after a long period of filtration, which will affect the water flow, increase the filtration pressure, and reduce the filtration effect. Generally, the filter material needs to be disassembled and cleaned, which is time-consuming and laborious.

[0041] Based on the above description, one or more embodiments of this application provide a dual-drum filter device. In the dual-drum filter device, the backwash nozzles arranged in parallel directly impact the filter layer with reverse water flow. Impurities can be discharged through the drain pipe without disassembling the filter layer, avoiding the cumbersome operation of frequently removing filter media required by traditional filter devices. This helps to extend the non-disassembly period and reduce the frequency of disassembly and maintenance.

[0042] The dual-drum filter device is described below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, the dual-drum filter device provided in this application embodiment includes a housing frame 1, at least one drum filter support frame 9, and a backwash assembly.

[0044] The housing frame 1 has an inlet 2 and a clean water outlet 1-3, both connected to the equipment to be filtered. A drum filter support frame 9 is located in the housing frame 1 and is covered with a filter layer. One end of the drum filter support frame 9 is connected to the inlet 2, and the other end extends out of the housing frame 1 to form a drain pipe 8. The clean water outlet 1-3 is located below the filter layer. The backwash assembly includes a backwash water pipe 6 connected to an external water source. The backwash water pipe 6 has multiple backwash nozzles 7 connected in parallel. The backwash nozzles 7 are arranged facing the filter layer and are configured to flush impurities attached to the filter layer so that the impurities are discharged from the housing frame 1 along the drain pipe 8.

[0045] As can be seen from the above description, the dual-drum filter device in this application embodiment connects the water inlet 2 and the clean water inlet 1-3 of the housing frame 1 to the equipment to be filtered (e.g., the tank of a fish tank). The water in the tank enters the drum filter support frame 9 through the water inlet 2, is filtered by the filter layer, and then flows back into the tank through the clean water inlet 1-3 to complete the filtration work. Since a backwash component is provided, the backwash nozzle 7 of the backwash component washes the filter layer, which can prevent impurities on the filter layer from clogging it, thereby automatically cleaning the filter layer, reducing manual intervention, and helping to reduce the frequency of cleaning and maintenance.

[0046] It should be noted that the water inlet 2 and the clean water inlet 1-3 of the tank frame 1 can both be connected to the tank body to perform self-circulating filtration of the water inside the tank body. In this scenario, a water pump can be installed in the tank body or the tank frame 1 to drive the water into the tank frame 1 for circulation filtration. Alternatively, in some embodiments, the connection positions of the water inlet 2 and the clean water inlet 1-3 can be changed. For example, the water inlet 2 can be connected to the tank body, and the clean water inlet 1-3 can be directly connected to other external water storage components, which in turn can be connected to the tank body.

[0047] like Figure 3 As shown in the embodiment of this application, there are two rotating drum filter support frames 9 arranged side by side, and the two rotating drum filter support frames 9 are driven to rotate by a driving component. An inlet is provided on one side of the rotating drum filter support frame 9 corresponding to the water inlet area 1-1. Setting two rotating drum filter support frames can increase the filtration area and improve the water processing capacity per unit time. Under the same water volume, the volume of the dual-drum is only half that of the single-drum, increasing the processing capacity by more than 50%.

[0048] The aforementioned drum filter support frame 9 can be made of polymer plastic or metal. The drum filter support frame 9 is a cylindrical skeleton, and the filter layer is wrapped around the outer periphery of the drum filter support frame 9. Generally, the filter layer can be made of nylon mesh, metal mesh, plastic mesh, or glass fiber mesh. The mesh size of the filter layer can be set according to the actual use scenario of the aquarium body, and this application embodiment does not make an absolute limitation on this.

[0049] Furthermore, such as Figure 4 As shown, flange rings 9-2 are respectively fitted on the same side of the two drum filter support frames 9, and a drive motor 3 is fixed on the box frame 1. The output end of the drive motor 3 is connected to the two drum filter support frames 9 in a transmission cooperation.

[0050] Specifically, the drum filter support frame 9 includes a frame body 9-3 and a mounting block 9-1 fixed on the frame body 9-3. A flange ring 9-2 is fitted and fixed on the mounting block 9-1. The flange ring 9-2 can be a gear flange with regular teeth on its outer circumference. The output shaft of the drive motor 3 drives the flange rings 9-2 of the two drum filter support frames 9 to rotate together through a central rotating gear 10.

[0051] Because there are two rotating drum filter support frames 9, the two rotating drum filter support frames 9 rotate synchronously. The two rotating drum filter support frames 9 are driven to rotate by a driving component, so that the backwash nozzle 7 can clean the filter layer at different angles alternately, which helps to improve cleaning efficiency and enhance the flushing effect. In addition, the two rotating drum filter support frames 9 can also provide emergency backup guarantee. When the filter layer on a single rotating drum filter support frame 9 is blocked, the other rotating drum filter support frame 9 can still continue to operate, avoiding the risk of system shutdown caused by single frame failure.

[0052] It should be noted that the number of drum filter support frames 9 can also be set to other quantities, which are driven by the drive motor 3 to rotate synchronously. Generally speaking, the more drum filter support frames 9 there are, the higher the filtration efficiency will be, but the cost and space occupied will also increase accordingly. Therefore, different numbers of drum filter support frames 9 can be set according to the actual volume, water capacity and other parameters of the aquarium.

[0053] In some embodiments, the interior of the housing frame 1 is divided by a partition to form a water inlet area 1-1 and an overflow area 1-2. The drum filter support frame 9 is located in the overflow area 1-2. The water inlet 2 is located on the side wall corresponding to the water inlet area 1-1. The clean water outlet 1-3 is located on the bottom plate of the overflow area 1-2.

[0054] In this embodiment, terms such as "above," "below," "bottom plate," and "side plate" with directional descriptions are used to describe the orientation of the filter device after it is assembled in the cylinder. Generally, after the filter device filters the water through the filter layer of the rotating drum filter support frame 9, the water falls to the clean water inlet 1-3 by gravity and flows back into the cylinder through the clean water inlet 1-3.

[0055] The overflow zone 1-2 and the inlet zone 1-1 are separated by design. The water flowing into the inlet zone 1-1 can initially settle and flocculate, reducing the filtration load on the drum filter support frame 9 in the overflow zone 1-2. At the same time, the inlet zone 1-1 is also convenient for observing the height of the filtered water, thereby preventing the filter layer from accumulating too many impurities and failing to filter properly.

[0056] Furthermore, the water flow direction is: inlet 2 → inlet zone 1-1 → overflow zone 1-2 → drum filter screen → clear water outlet 1-3 → aquarium rod. When the water level in inlet zone 1-1 exceeds the design height of the float valve 5, excess water directly enters the filter screen corresponding to the drum filter screen support frame 9 through overflow zone 1-2, avoiding the risk of overflow. Generally, the height of the baffle is slightly higher than the water level warning height of the float valve 5. When the water level in inlet zone 1-1 rises to the water level warning height, the float valve 5 drives the motor 3 to drive the backwash nozzle 7 to flush the filter layer. When the water level continues to rise above the height of the baffle, the water flows directly from inlet zone 1-1 through the baffle into overflow zone 1-2, is directly filtered by the drum filter screen, and the water supply from inlet 2 is suspended until the water level returns to normal.

[0057] In the above embodiment, the backwash assembly further includes a backwash water pump 4, the pumping end of which is connected to the inlet zone 1-1, and the output end of which is connected to the backwash water pipe 6. A water level float valve 5 is also installed in the housing frame 1, located on the side wall of the inlet zone 1-1, with its height higher than the inlet 2. This higher height of the float valve 5 prevents backflow of water into the tank due to excessive blockage of the overflow zone 1-2, ensuring the normal operation of the dual-drum filter device.

[0058] The water level float valve 5 can be a water level float valve, which is directly connected to the backwash water pump 4 to control the start and stop status of the backwash water pump 4. The water level float valve 5 and the water inlet area 1-1 inside the housing frame 1 can achieve a certain water storage function. When too many impurities adhere to the filter layer inside the drum filter support frame 9, the water flow filtration efficiency slows down, and the water level in the water inlet area 1-1 rises. After detecting the water level height, the water level float valve 5 sends a signal to start the backwash water pump 4 to pump water and flush the filter layer.

[0059] In the above embodiments, the pumping end of the backwash water pump 4 can also be connected to an external water supply device, as long as the backwash nozzle 7 can be used to flush the filter layer to avoid clogging of the filter layer.

[0060] In addition, in some embodiments, the water inlets 1-3 are mesh inlets located at the bottom of the housing frame 1. This design can form a double-layer filtration effect with the filter layer of the drum filter support frame 9, preventing impurities from leaking out and directly entering the cylinder.

[0061] In some embodiments, an impurity collection box 9-4 is fixed on the housing frame 1. The impurity collection box 9-4 is located in the drum filter support frame 9, and the opening of the impurity collection box 9-4 is arranged facing the backwash nozzle 7. The impurity collection box 9-4 is connected to the drain pipe 8, and the backwash nozzle 7 washes the impurities on the filter layer so that the impurities are sent into the drain pipe 8 through the impurity collection box 9-4.

[0062] In the above embodiment, the impurity collection box 9-4 is a rectangular box with its opening facing upwards, corresponding to the rinsing direction of the backwash nozzle 7. Since the impurity collection box 9-4 is fixed on the housing frame 1, the rotation of the drum filter support frame 9 will not affect the direction of the impurity collection box 9-4, and the filter layer during the rotation process can be rinsed by the backwash nozzle 7, so that the rinsed impurities fall into the impurity collection box 9-4 and are then discharged from the housing frame 1 through the drain pipe 8.

[0063] An exemplary usage process of the dual-drum filter device according to an embodiment of this application is as follows:

[0064] In use, the dual-drum filter device is fixed on the cylinder body. Water is drawn from the cylinder body into the water inlet area 1-1 of the housing frame 1 by a water pump. After entering the drum filter support frame 9 through the partition, the water is filtered by the filter layer on the drum filter support frame 9. The filtered water flows back into the cylinder body through the clean water inlet 1-3. The filtered impurities adhere to the filter layer. As the impurities accumulate, the water level in the water inlet area 1-1 rises. After the water level float valve 5 detects the water level, it controls the backwash water pump 4 to draw water and backwash the filter layer through the backwash nozzle 7. The impurities on the filter layer fall into the impurity collection box 9-4 and are discharged from the housing frame 1 through the drain pipe 8.
