Description

Technical Field

[0001] This utility model relates to the field of filter barrels, and in particular to a filter component suitable for high-flow filter barrels. Background Technology

[0002] To ensure a suitable growth environment for aquatic organisms in aquariums, a circulating filtration system is typically installed. Canister filters, due to their ease of assembly and wider applicability to various water types, are widely used. However, existing canister filters have diverse filter cartridge designs, each with its own drawbacks. To address this, the applicant previously proposed a technical solution (application number: 2024212303593), disclosing a filter component for canister filters. This solution effectively separates water and wastewater, reduces the pressure on the filter media in the filter media chamber from nitrification and ammonia decomposition, and provides multi-stage interception and thorough sedimentation of solid particles, stabilizing the sediment and preventing it from re-entering the water circulation system.

[0003] However, this technical solution still has shortcomings. The main shortcoming is that when a small-volume filter tank is used with a high-power filter water pump, the water flow rate inside the tank is relatively large and the flow velocity is relatively fast. Some of the water in the tank falls to the bottom and then tumbles and agitates due to inertia. Under these unconventional working conditions, the solid particles entering the sedimentation chamber will tumble, pulverize, and affect the filtration effect of the water flow inside the tank.

[0004] Secondly, when using a variable frequency water pump, the water flow rate inside the tank increases when the pump switches from a certain power to a relatively high power. When this increases to a certain extent, it stirs up the solid particles that have been deposited at the bottom of the sedimentation tank, causing them to churn and pulverize over time. Furthermore, some of the solid particles that have been deposited at the bottom of the sedimentation tank float to the top of the tank after prolonged soaking. As the water flow rate increases, the disturbance in the sedimentation tank deepens, causing existing floating debris to churn and pulverize, thus affecting the filtration effect of the water flow inside the tank.

[0005] Furthermore, the fine particles that have been pulverized in the sedimentation chamber will participate in the filtration cycle again with the overflow water flow, increasing the filtration and nitrification burden on the filter cotton and filter media in the filter media chamber, and increasing the deposition of ammonia, nitrogen and nitrite in the aquarium water. Under the aforementioned unconventional conditions, the frequency of cleaning and maintenance of the filter canister will also increase.

[0006] Furthermore, existing technical solutions still have varying degrees of technical shortcomings when facing the high-flow filtration needs of large aquariums and aquaculture facilities. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of existing technologies, supplement and improve existing technical solutions, and provide a sedimentation and filtration component with targeted functions that can overcome specific technical weaknesses. This filtration component is movably installed inside the filter tank. By setting a dirt-binding mesh and dirt-binding baffle structure inside the sedimentation chamber, it can still avoid or significantly reduce the problems of solid particles entering the sedimentation chamber churning, pulverizing, and floating, even under the aforementioned unconventional operating conditions. It is particularly effective in intercepting and settling sediment in high-flow-rate filtered water environments, making it a filtration component suitable for high-flow-rate filter tanks.

[0008] This filter component includes a water pipe, a filter media bin bottom plate, a filter screen cylinder, a sedimentation bin partition, a settling pipe, a dirt-binding screen cover, and a dirt-binding baffle, and this filter component is movably installed inside the filter barrel;

[0009] The water pipe is a tube with openings at both the top and bottom, used to connect to the water flow to be filtered;

[0010] The lower part of the water pipe is provided with a filter media compartment bottom plate, and the filter media compartment bottom plate is provided with a water passage hole and an assembly hole A, and the assembly hole A is tightly fitted with the lower part of the water pipe;

[0011] A sedimentation tank partition is provided at intervals on the lower side of the bottom surface of the filter media tank bottom plate, and the sedimentation tank partition is provided with assembly holes B;

[0012] A filter screen cylinder is installed at the bottom of the water pipe. The filter screen cylinder is a type of screen cylinder with openings at both the top and bottom. The filter screen cylinder is located between the bottom plate of the filter media bin and the partition plate of the sedimentation bin.

[0013] A settling pipe is provided at the lower part of the filter screen cylinder. The settling pipe is a tube with openings at both the top and bottom. The settling pipe passes downward through the assembly hole B.

[0014] The space between the bottom plate of the filter media bin and the partition of the sedimentation bin is the water and wastewater diversion area;

[0015] The bottom surface of the partition plate of the sedimentation tank is the sedimentation tank itself;

[0016] A filthy net is provided on the bottom surface of the partition of the sedimentation tank. The filthy net is located inside the sedimentation tank and is positioned between the settling pipe and the inner wall of the sedimentation tank. The filthy net is in close fit with the settling pipe.

[0017] Fouling baffles are provided at intervals on the bottom surface of the sedimentation tank partition. The fouling baffles are located inside the sedimentation tank and are positioned between the fouling mesh and the inner wall of the sedimentation tank. The outer edge of the fouling baffle is in close contact with the inner wall of the sedimentation tank, and the inner side of the fouling baffle is in close contact with the fouling mesh. The inner surface of the fouling baffle is also spaced apart from the settling pipe.

[0018] The effect achieved is that the components of this utility model are movably assembled inside the filter barrel, with the bottom plate of the filter media bin and the partition of the sedimentation bin as the interval. Through structural combination, a water and sewage diversion area, a sedimentation bin and a filter media bin are formed inside the filter barrel. At the same time, an intercepting and trapping mesh cover and a trapping baffle structure are set in the sedimentation bin.

[0019] The beneficial effects of this utility model component are as follows: Through the structural combination of this utility model component, the problems of solid particles entering the sedimentation chamber churning, pulverizing, and floating can be avoided or significantly reduced. The filter canister composed of this component has improved adaptability in practical applications, its internal sedimentation, filtration, and dirt-binding capacity is greatly enhanced, and the component can be detached from the canister body for convenient maintenance and cleaning. In this case, the functions of each section within the filter canister are clearly defined and effectively coordinated, minimizing the secondary participation of solid particles in the water circulation within the filter canister from the sedimentation chamber, minimizing the pressure on the filter media in the filter media chamber for nitrification and ammonia nitrogen decomposition, and reducing the occurrence of filter screen and filter cotton clogging problems within the filter canister. The filter canister using the filter component described in this utility model can adapt to the needs of larger filtered water flows and can also effectively reduce the frequency of cleaning and maintenance of the filter canister.

[0035] Preferably, the filter media compartment is filled with a filter cotton pad, filter media, or a filter basket;

[0036] Preferably, the filter screen cylinder 3 is disposed below the filter media bin bottom plate 2, with its upper edge tightly fitted to the mounting hole A9 on the filter media bin bottom plate 2, and its lower edge tightly fitted to the upper end of the settling pipe 5.

[0037] Preferably, the filter cylinder 3 can be one or more of the following: filter screen, filter cotton, and perforated tube;

[0038] A settling pipe 5 is provided at the lower part of the filter cylinder 3. The settling pipe 5 is a tube with openings at both the top and bottom. The settling pipe 5 passes downward through the assembly hole B10.

[0039] The space formed inside the filter barrel 8 cavity between the filter media bin bottom plate 2 and the sedimentation bin partition 4 is the water and sewage diversion area 11.

[0040] The space formed by the bottom surface of the sedimentation tank partition 4 inside the filter barrel 8 is the sedimentation tank 12; and the plate portion surrounding the sedimentation tank 12 is the inner wall of the sedimentation tank 12.

[0041] A dirt-binding mesh cover 6 is provided on the bottom surface of the sedimentation tank partition 4. The dirt-binding mesh cover 6 is located inside the sedimentation tank 12. The dirt-binding mesh cover 6 is disposed between the settling pipe 5 and the inner wall of the sedimentation tank 12, and the dirt-binding mesh cover 6 is tightly fitted with the settling pipe 5.

[0042] Preferably, the dirt-binding mesh cover 6 can be one or more of a filter screen and filter cotton;

[0043] A dirt-binding baffle 7 is provided at intervals on the bottom surface of the sedimentation tank partition 4. The dirt-binding baffle 7 is located inside the sedimentation tank 12. The dirt-binding baffle 7 is disposed between the dirt-binding mesh cover 6 and the inner wall of the sedimentation tank 12. The outer edge of the dirt-binding baffle 7 is tightly fitted to the inner wall of the sedimentation tank 12. The inner side of the dirt-binding baffle 7 is tightly fitted to the dirt-binding mesh cover 6. The inner surface of the dirt-binding baffle 7 is spaced apart from the settling pipe 5.

[0044] Furthermore, the bottom surface of the contaminant baffle 7 is provided with an arc-shaped guide plate 14. There are one or more arc-shaped guide plates 14. When there are multiple arc-shaped guide plates 14, they are arranged in such a way that multiple arc-shaped guide plates 14 are spaced apart on the bottom surface of the contaminant baffle 7.

[0045] Example 1:

[0046] An arc-shaped guide plate 14 is provided below the baffle 7. The arc-shaped guide plate 14 is a vertical curved plate. The arc-shaped guide plate 14 is vertically arranged between the baffle 7 and the bottom plate of the sedimentation tank 12. The upper end of the arc-shaped guide plate 14 is tightly connected to the baffle 7, and the lower end of the arc-shaped guide plate 14 is tightly fitted to the bottom plate of the sedimentation tank 12. The open side of the arc-shaped guide plate 14 corresponds to the inner wall of the sedimentation tank 12 and is spaced apart from the inner wall of the sedimentation tank 12. The closed side of the arc-shaped guide plate 14 corresponds to the settling pipe 5 and is spaced apart from the settling pipe 5. The outer sides of the two vertical plates of the arc-shaped guide plate 14 are spaced apart from the inner wall of the sedimentation tank 12.

[0047] Preferably, with the settling pipe 5 as the center, multiple arc-shaped guide plates 14 are arranged at intervals below the dirt-binding baffle 7, and there is a guide channel between each arc-shaped guide plate 14 and the spaced arc-shaped guide plates 14.

[0048] The effect achieved is that solid particles falling into the bottom of the sedimentation tank 12 are blown by the water flow, guided by the arc-shaped guide plate 14, and then enter and settle in the gap formed by the sludge conveying channels on both sides of the arc-shaped guide plate 14, the sludge baffle 7, the arc-shaped guide plate 14, the bottom plate of the sedimentation tank 12 and the inner wall of the sedimentation tank 12, waiting to be discharged from the filter bucket 8. The arc-shaped guide plate 14 acts like a check valve, which can greatly reduce the problem of solid particles falling into the bottom of the sedimentation tank 12 flowing back again, and can greatly reduce the problem of solid particles falling into the bottom of the sedimentation tank 12 churning and pulverizing.

[0049] In addition, the arc-shaped guide plate 14 can also serve as a support for the dirt-binding baffle 7, ensuring the stability of the dirt-binding baffle 7 in the filter component, and thus ensuring the stability of the dirt-binding mesh cover 6 in the filter component.

[0050] Example 2:

[0051] A sedimentation tank support plate 15 extends downward from the outer edge of the sedimentation tank partition 4. The sedimentation tank support plate 15 is provided with a large drainage hole 16 and a small pressure relief hole 17.

[0052] Preferably, the sedimentation tank support plate 15 is provided with a plurality of support plate pressure relief holes 17.

[0053] The effect achieved is that the sedimentation tank support plate 15 supports the sedimentation tank partition plate 4, improves the load-bearing capacity of the sedimentation tank partition plate 4, and improves the stability of the filter components.

[0054] The sedimentation tank support plate 15 and the sedimentation tank partition plate 4 are connected in a sealed manner to ensure that the water in the sedimentation tank 12 will not overflow into the water and sewage diversion area in a disorderly manner, and the inner wall of the sedimentation tank support plate 15 can be used as the inner wall of the sedimentation tank 12.

[0055] The drainage holes 16 on the support plate create a channel for the water and solid particles entering the sedimentation tank 12 to be discharged out of the filter tank 8.

[0056] The pressure relief hole 17 of the support plate establishes an upward channel for the excess water flow entering the sedimentation tank 12, reducing the force of the water flow impacting the solid particles in the sedimentation tank 12. Due to the pressure equalization relationship, the flushing force and upward drainage volume of the water flow entering the sedimentation tank 12 through the settling pipe 5 are limited by the pressure relief hole 17 of the support plate.

[0057] Preferably, with the premise of effectively flushing solid particles to the position below the baffle plate 7 and avoiding or reducing their pulverization, the appropriate number and diameter of the support plate pressure relief holes 17 can be flexibly selected.

[0058] Example 3:

[0059] The filter element suitable for high-flow filter barrel 8 is movably installed inside the filter barrel 8;

[0060] The filter bucket 8 includes a bucket body and a bucket lid, and the bucket body and the bucket lid are connected by a plug-in connection or a threaded connection.

[0065] The water inlet and backwash port A20 and the water inlet and backwash port B21 are respectively located on both sides of the water outlet port 19.

[0066] Preferably, any two of the water outlet 19, water inlet and backwash outlet A20 and water inlet and backwash outlet B21 are provided with water inlet and outlet valves 25, and the sewage outlet 18 is provided with sewage discharge valve 26.

[0067] The inlet and outlet valves 25 and outlet pipe 19, inlet and backwash pipe A20 or inlet and backwash pipe B21 are all plug-in or screw-in.

[0068] The sewage valve 26 and the sewage outlet 18 are connected by plug or screw;

[0069] A support slide 28 is movably disposed below the inlet / outlet valve 25;

[0070] The inlet and backwash port A20 or the inlet and backwash port B21 are each equipped with a separate cap 27 for connection, and they are interchangeable.

[0071] The effect achieved is that the barrel body and the barrel cover are separated, which is convenient for cleaning and maintenance; the sewage outlet 18 can discharge the sewage in the filter barrel 8; the water outlet can evenly discharge the water overflowing after being filtered by the filter media in the filter media chamber, and can ensure that the water flow is evenly distributed and overflowing in the filter chamber; the water inlet and backwash outlet A20 and the water inlet and backwash outlet B21 can be interchanged. The water inlet and backwash outlet A20 and the water inlet and backwash outlet B21 have the functions of water inlet, backwashing and air venting at the same time. At the same time, this setting allows the filter barrel 8 to be more flexibly installed on the left or right side of the fish tank or pool, which means that the pipeline installation is simple and beautiful.

[0072] Meanwhile, the inlet and outlet valves 25 are used to control the water flow at the outlet 19, inlet and backwash outlet; the wastewater valve 26 controls the discharge of wastewater from the filter tank 8; when the plane angle of the inlet and outlet valves 25 needs to be adjusted, the inlet and outlet valves 25 can be finely adjusted to the predetermined plane angle; after the plane angle is finely adjusted, the inlet and outlet valves 25 are supported by the support slide 28, which can bear the weight of the external inlet and outlet pipes; when one of the inlet and backwash outlets is not in use, the cap 27 can be used to seal it, or the tightness of the cap 27 can be finely adjusted to release air when the filter tank 8 is backwashed or refilled after cleaning and maintenance.

[0073] Example 4:

[0074] The upper part of the water pipe 1 is provided with a perforated water pipe cap 22; the cap of the water pipe 1 is provided with an assembly hole; the assembly hole on the cap of the water pipe 1 is connected to the lower part of the water inlet pipe 23; the upper part of the water inlet pipe 23 is connected to one of the water inlet and backwash port A20 or the water inlet and backwash port B21.

[0075] Water pipe 1 is connected to water pipe 1 cap by plug or screw;

[0076] The perforated water pipe cap 22 is inserted into or screwed into the water inlet pipe 23;

[0077] The connection between the water inlet pipe 23 and the water inlet and backwash port A20 or the water inlet and backwash port B21 is either a plug-in connection or a screw connection.

[0078] The effect achieved is that the water pipe 1, the perforated water inlet pipe 23 cap, the water inlet pipe 23 are connected and tightly fitted with the water inlet and backwash port A20 or the water inlet and backwash port B21, ensuring that the filtered water will not escape directly into the filter media compartment after entering the filter bucket 8.

[0079] The water to be filtered outside the filter bucket 8 enters the filter bucket 8 through the inlet and backwash pipe port A20 or the backwash pipe port B. The water to be filtered continues to flow through the inlet pipe 23, the perforated water pipe cap 22, and the water pipe 1. After passing through the filter screen cylinder 3 once for water and sewage separation, the solid particles sink with the inertia of the water flow into the settling pipe 5. Then, the solid particles enter the area below the flow net and are washed to the position below the dirt baffle 7 and deposited. The deposited solid dirt particles are discharged from the filter bucket 8 outside the filter bucket 8 from the sewage outlet 18 from time to time.

[0080] The water inlet pipe 23 is connected to either the water inlet and backwash port A20 or the water inlet and backwash port B21, while the other water inlet and backwash port can be reserved for backwashing or venting purposes.

[0081] The perforated inlet pipe 23 cap also facilitates the use of various forms of inlet pipe 23.

[0082] Example 5:

[0083] The inlet pipe 23 is a bend, and the water pipe 1 is centrally located on the center line of the filter barrel 8.

[0084] The arc-shaped guide plates 14 are uniformly arranged in an array below the dirt baffle 7.

[0085] The effect achieved is to meet the filtration requirements for general water flow and to be suitable for flushing and sedimentation filtration of small and medium-sized solid particles.

[0086] Example 6:

[0087] The inlet pipe 23 is a straight pipe, and the water pipe 1 is located on one side of the filter barrel 8.

[0088] The arc-shaped guide plate 14 is arranged in a fan-shaped array below the dirt baffle 7 with the settling pipe 5 as the reference point.

[0089] The effect achieved is to meet the needs of filtration for larger water flow rates, and it is suitable for sedimentation of medium and large solid particles.

[0090] Example 7:

[0091] Supporting ribs 24 are provided between the bottom plate 2 of the filter media bin and the partition plate 4 of the sedimentation bin, as well as on the bottom surface of the partition plate 4 of the sedimentation bin.

[0092] Preferably, there are multiple supporting ribs 24.

[0093] This achieves the effect of providing stable support for the filter components inside the filter barrel.

[0094] Example 8:

[0095] The aforementioned dirt-binding mesh cover 6 and dirt-binding baffle 7 are provided with assembly holes.

[0096] Preferably, the dirt trap 6 and dirt trap baffle 7 are provided with a plurality of assembly holes.

[0097] The effect achieved is that the multiple support ribs 24 provided on the bottom surface of the sedimentation tank partition 4 can all pass downward through the mounting holes on the dirt trap 6 and dirt trap baffle 7, thereby cooperating with the sedimentation tank support plate 15 to provide a support base for the equipment.

[0098] Example 9: A secondary filter cylinder 13 is also provided outside the filter cylinder 3. The secondary filter cylinder 13 is connected to the outer settling pipe 29, and the outer settling pipe 29 is provided with a water passage hole in the hollow section of the outer settling pipe 29.

[0099] The outer settling pipe 29 and the settling pipe 5 are spaced apart, and the chamber between the outer settling pipe 29 and the settling pipe 5 is connected to the chamber between the filter screen cylinder 3 and the secondary filter screen cylinder 13.

[0100] The effect achieved is that the secondary filter cylinder 13 can add a first-level filtration to intercept pollutant particles in the water; the setting of the outer settling pipe 29 can guide the solid particles intercepted by the secondary filter cylinder 13 downward and make them sink into the sedimentation tank 12, waiting to be discharged from the filter barrel 8 during backwashing.

[0101] The effect achieved is that the inlet and outlet valves 25 control the water flow at the outlet 19, inlet, and backwash inlet; the wastewater valve 26 controls the discharge of wastewater from the filter tank 8; when the plane angle of the inlet and outlet valves 25 needs to be adjusted, the inlet and outlet valves 25 can be finely adjusted to the predetermined plane angle; after finely adjusting the plane angle, the inlet and outlet valves 25 are supported by the support slide 28, which can bear the weight of the external inlet and outlet pipes; when one of the inlet and backwash inlets is not in use, it can be sealed with the cap 27, or the tightness of the cap 27 can be finely adjusted to release air when backwashing the filter tank 8 or when refilling water after cleaning and maintenance.
