Description

Technical Field

[0001] This application relates to the field of water treatment technology, specifically an integrated water purifier with multi-stage filter tanks, suitable for household or commercial water purification. Background Technology

[0002] Water purifiers are widely used in domestic and industrial applications to remove suspended solids, heavy metals, chlorine, and other contaminants from water. Currently, filter tanks are often made of fiberglass, which offers advantages such as corrosion resistance and light weight. However, fiberglass tanks are prone to aging and cracking during long-term use, and their simple internal structure limits their filtration efficiency.

[0003] Home central water purifiers typically use a single filter tank or a simple series connection, which has the following drawbacks: First, the number of filtration stages is limited, making it unable to effectively remove multiple contaminants (such as heavy metals and residual chlorine); second, they are bulky, making installation and maintenance inconvenient; and third, filter media replacement is frequent, resulting in high operating costs. Industrial water purifiers, while having a large processing capacity, have a complex structure, requiring multiple independent tanks connected by pipes, occupying a large space, and have many interfaces prone to leakage, making maintenance difficult.

[0004] For example, the prior art disclosed in CN217698079U is an activated carbon filter tank for water treatment, which uses a water distribution component to distribute water evenly and improve water purification capacity. However, this solution only involves a single filter tank, cannot achieve the synergistic effect of multi-stage filtration, and does not solve the problem of a compact integrated structure. Utility Model Content

[0005] The purpose of this invention is to solve the problem of compact integrated structure and provide an integrated water purifier with multi-stage filter tanks. Multiple filter tanks are compactly connected by a tubular multi-channel connector to achieve efficient multi-stage filtration while reducing space occupation and leakage risk.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated water purifier with multi-stage filter tanks includes a first filter tank and a second filter tank, which are respectively fixed at both ends of a tubular multi-channel connector, wherein an inlet and an outlet are respectively provided on both sides of the tubular multi-channel connector.

[0008] The inlet is connected to the first filter tank through the first channel located in the tubular multi-channel joint;

[0009] The first filter tank is connected to the second filter tank through a second channel located in a tubular multi-channel joint;

[0010] The second filter tank is connected to the outlet via a third channel located within a tubular multi-channel connector.

[0011] In one feasible embodiment, the first filter canister has a first tube located on its axis, one end of which is connected to a second channel, and the other end is close to the inner bottom of the first filter canister.

[0012] In one feasible embodiment, the second filter canister has a second tube located on its axis, one end of which is connected to the third channel, and the other end is close to the inner bottom of the second filter canister.

[0013] In one feasible embodiment, the outlet of the first channel is located outside the first tube, and the outlet of the first channel is provided with a first protective structure that is in close contact with the outer surface of the first tube.

[0014] In one feasible embodiment, a first filter structure is provided at the end of the first tube.

[0015] In one feasible embodiment, the outlet of the second channel is located outside the second pipe, and the outlet of the second channel is provided with a second protective structure that is in close contact with the outer surface of the second pipe.

[0016] In one feasible embodiment, a second filter structure is provided at the end of the second tube.

[0017] In one feasible embodiment, a fourth channel is provided on the second channel, the fourth channel is sealed by a threaded plug, and the fourth channel is configured to be detachably connected to an external connecting pipe.

[0018] The armature assembly pressing fixture proposed in this utility model has the following advantages: This technical solution achieves integrated connection of multi-stage filter tanks through a tubular multi-channel joint, resulting in a compact structure, reduced pipe joints and leakage risks, and suitability for space-constrained applications. The series design of the multi-stage filter tanks allows for the configuration of filter media for different contaminants, significantly improving water purification efficiency, such as for heavy metal removal and chlorine removal. Furthermore, the added protective and filtration structures effectively prevent filter media loss and clogging, extending equipment lifespan. The addition of a fourth channel facilitates expansion connections and maintenance, enhancing practicality. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-7 An integrated water purifier with multi-stage filter tanks includes a first filter tank 1 and a second filter tank 2. In this embodiment, the first filter tank 1 and the second filter tank 2 use composite material pressure tanks as inner tanks, and glass fiber is wound on the inner tanks to form a glass fiber layer.

[0030] The first filter tank 1 and the second filter tank 2 are respectively fixed at both ends of the tubular multi-channel connector 3, wherein the tubular multi-channel connector 3 is provided with an inlet 4 and an outlet 5 on both sides; the inlet 4 is connected to the first filter tank 1 through the first channel 31 located in the tubular multi-channel connector 3; the first filter tank 1 is connected to the second filter tank 2 through the second channel 32 located in the tubular multi-channel connector 3; the second filter tank 2 is connected to the outlet 5 through the third channel 33 located in the tubular multi-channel connector 3.

[0031] In this embodiment, the first filter tank 1 has a first tube 11 located on its axis. One end of the first tube 11 is connected to the second channel 32, and the other end is close to the inner bottom of the first filter tank 1. The outlet of the first channel 31 is outside the first tube 11, and a first protective structure 34 is provided at the outlet of the first channel 31, which is in close contact with the outer surface of the first tube 11. Furthermore, a first filter structure 12 is provided at the end of the first tube 11.

[0032] In this embodiment, the second filter tank 2 has a second tube 21 located on its axis. One end of the second tube 21 is connected to the third channel 33, and the other end is close to the inner bottom of the second filter tank 2. The outlet of the second channel 32 is outside the second tube 21, and a second protective structure 35 is provided at the outlet of the second channel 32, which is in close contact with the outer surface of the second tube 21. Furthermore, a second filter structure 22 is provided at the end of the second tube 21.

[0033] In another technical solution, a fourth channel 36 is provided on the second channel 32. The fourth channel 36 is sealed by a threaded plug 37 and is configured to be detachably connected to an external connecting pipe.

[0034] To achieve household water purification, such as removing heavy metals and chlorine, this embodiment uses a multi-stage filter tank connected in series. The first filter tank 1 is filled with quartz sand filter media to remove suspended solids, silt, and other large particles, providing clean inlet water for subsequent filter tanks. The second filter tank 2 is filled with activated carbon and KDF. The KDF filter media layer, located near the inlet of the second filter tank 2, is 30-40cm thick and occupies 30%-40% of the effective volume of the second filter tank 2. It removes heavy metals (lead, mercury, chromium, etc.), inhibits microbial growth, and removes some residual chlorine. The activated carbon filter media layer, located near the outlet of the second filter tank 2, is 60-80cm thick and occupies 60%-70% of the effective volume of the second filter tank 2. It deeply adsorbs and removes residual chlorine, organic matter, discoloration, and odors, further improving water quality. The bottom of the second filter tank 2 is covered with a layer of pebbles, which is 5cm-10cm thick. This layer is mainly used to support the activated carbon layer above and prevent it from being lost from the bottom.

[0035] The entire water flow path is as follows: raw water enters from inlet 4, flows into the first filter tank 1 through the first channel 31, is filtered by quartz sand from the top of the first filter tank 1, and then enters the second filter tank 2 through the first pipe 11 and the second channel 32; then it passes through the KDF filter media and activated carbon layer at the bottom of the second filter tank 2 and reaches the second pipe 21, where a pebble layer is laid at the bottom of the second filter tank 2; finally, it flows out from the outlet 5 through the second pipe 21 and the third channel 33 to obtain purified water.

[0036] A fourth channel 36 is provided on the second channel 32 and sealed by a threaded plug 37. If necessary, such as for maintenance or expansion, the threaded plug 37 can be removed to add a connecting pipe for backwashing or to connect an additional filter tank.
