Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to an independent water washing treatment device, and also to a wastewater purification system having the independent water washing treatment device. Background Technology

[0002] Wastewater typically contains a large amount of harmful substances, requiring purification to remove these substances and mitigate the impact of discharge. Wastewater is mostly liquid, with a small amount of sediment and impurities. Treatment usually involves filtering the wastewater first, followed by further purification of the filtrate, with treatment tailored to the level of pollution. However, sediment and impurities in wastewater are often disposed of via landfill, easily overlooking their pollution status.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an independent water washing treatment device and a sewage purification system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An independent water washing treatment device includes a water washing container, an inlet pipe, a slag discharge pipe, and a drain pipe. The inlet pipe has a first inlet pipe end and a second inlet pipe end. The first inlet pipe end extends into the water washing container from the bottom, and the second inlet pipe end is located outside the bottom of the water washing container. A slag discharge port is opened at the bottom of the water washing container, and the inlet pipe is connected to the slag discharge port. A drain outlet is opened on the side wall of the water washing container, and the drain pipe is connected to the drain outlet, with the height of the drain outlet being higher than the highest point of the inlet pipe.

[0007] It also includes a vent pipe, which has a first vent pipe end and a second vent pipe end. The first vent pipe end extends from the side wall of the washing container into the washing container, and the second vent pipe end is located on the upper outer side of the washing container. A mud and sand sedimentation layer is formed in the lower layer of the washing container, and the first vent pipe end extends into the mud and sand sedimentation layer.

[0008] The present invention is further configured such that the vent pipe is connected to an external pressure air source for aeration of the mud and sand sediment layer in the washing container; and the top of the washing container is provided with an air pressure balance port.

[0009] The present invention is further configured such that the inner diameter of the first end of the vent pipe is not less than 5 cm.

[0010] The present invention is further configured such that a baffle plate is fixedly connected to the inner side wall of the washing container, the baffle plate being located at the lower inner side of the drain outlet and at the upper part of the second end of the inlet pipe.

[0011] The present invention is further configured such that the baffle plate is inclined, gradually tilting upwards in the direction away from the drain outlet, and the highest point of the baffle plate is higher than the drain outlet.

[0012] The present invention is further configured to include an external pipe and a dosing pipe, wherein one end of the external pipe is connected to the second end of the vent pipe and the other end is connected to an external pressurized air source; the dosing pipe is connected to the external pipe and adds a chemical agent into the water washing container.

[0013] The present invention is further configured such that the dosing pipe is equipped with a check valve, which allows for unidirectional flow in the direction of the external pipe connection.

[0014] The present invention is further configured such that the external connecting pipe includes a straight section one, an inclined section and a straight section two connected in sequence, the straight section two being higher than the straight section one, and the inclined section being located between the straight section one and the straight section two to form an inclined transition; the straight section one is connected to the second end of the venting pipe, and the dosing pipe is connected to the upper side of the straight section one.

[0015] The present invention is further configured such that the slag discharge port is located at the lowest point of the bottom of the washing container, and the slag discharge pipe is equipped with a valve.

[0016] This utility model also provides a wastewater purification system, including the independent water washing treatment device as described above, which can separate particulate matter in wastewater and perform centralized washing treatment on the separated particulate matter.

[0017] In summary, this utility model has the following beneficial effects:

[0018] By extending the inlet pipe into the washing container and positioning the outlet at the top of the container, heavier particles settle to the bottom of the container after entering. This allows for the separation of particulate matter and liquid wastewater through a brief settling process. The drain outlet is located on the upper outer side of the container, creating a height difference with the bottom sediment, making it difficult for the sediment to be discharged from the drain outlet.

[0019] By installing a venting pipe and a dosing pipe, the venting pipe can introduce aeration gas into the bottom of the washing container, and then introduce gas into the sediment layer to agitate the sediment particles at the bottom; and the dosing pipe can add treatment agents to the wastewater to wash and purify the wastewater and the particles in it, eliminating the pollution effects.

[0020] Wastewater can be transferred and treated using a water-washing container. During treatment, the wastewater first passes through the container, into which treatment agents are added. These agents treat not only liquid pollutants but also solid matter. Furthermore, during the treatment process, impurities in the wastewater settle at the bottom of the container, accumulating sediment and effectively purifying the wastewater.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment discloses an independent water washing treatment device, referring to... Figures 1-3 As shown, it includes a water washing container 1, a water inlet pipe 2, a slag discharge pipe 3, and a drain pipe 4. The water washing container 1 is roughly cylindrical in shape, with arc-shaped structures at both the top and bottom ends.

[0028] The water inlet pipe 2 has a first end 21 and a second end 22. The first end 21 extends into the water washing container 1 from the bottom, while the second end 22 is located outside the bottom of the water washing container 1. The connection between the water inlet pipe 2 and the bottom of the water washing container 1 is sealed to prevent leakage.

[0029] A slag discharge port 31 is provided at the bottom of the washing container 1, and the slag discharge port 31 is located at the lowest point of the bottom of the washing container 1. The water inlet pipe 2 is connected to the slag discharge port 31. In addition, a valve is installed on the slag discharge pipe 3, and the opening and closing of the slag discharge pipe 3 can be controlled by the valve.

[0030] A drain outlet 41 is provided on the side wall of the washing container 1, and the drain outlet 41 is located on the upper side of the side wall of the washing container 1. The drain pipe 4 is connected to the drain outlet 41, and the height of the drain outlet 41 is higher than the highest point of the inlet pipe 2.

[0031] In this embodiment, the washing container 1 is also connected to an air vent pipe 6, which is used to introduce other substances into the bottom of the washing container 1 to aerate and agitate it, so as to prevent the sediment layer 100 at the bottom of the washing container 1 from becoming stagnant for a long time and forming a hard crust.

[0032] The vent pipe 6 has a first vent pipe end 61 and a second vent pipe end 62. The first vent pipe end 61 extends from the side wall of the washing container 1 into the washing container 1, and the second vent pipe end 62 is located on the upper outer side of the washing container 1. A sedimentary layer 100 is formed in the lower layer of the washing container 1, and the first vent pipe end 61 extends into the sedimentary layer 100.

[0033] To supply air to the vent pipe 6, an appropriate external pressurized air source can be used. The vent pipe 6 is connected to the external pressurized air source, enabling aeration of the sediment layer 100 in the washing container 1. A pressure balance port 11 is provided at the top of the washing container 1 to maintain pressure balance inside the washing container 1.

[0034] In a static state, the sediment layer 100 at the bottom of the washing container 1 may partially enter the vent pipe 6. If the static state is maintained for a long time, it may cause blockage in the vent pipe 6. In this embodiment, by increasing the inner diameter of the first end 61 of the vent pipe, generally not less than 5 cm, and providing a larger opening, blockage can be avoided.

[0035] Reference Figure 4 As shown, this embodiment also includes an external pipe 7 and a dosing pipe 8. One end of the external pipe 7 is connected to the second end 62 of the vent pipe, and the other end is connected to an external pressurized air source. The dosing pipe 8 is connected to the external pipe 7 and can add chemicals into the washing container 1. When it is necessary to add chemicals to the washing container 1, the required chemicals can be added to the dosing pipe 8 to purify particulate impurities and wastewater in the washing chamber.

[0036] The dosing pipe 8 is also equipped with a check valve 81. The check valve 81 can flow in one direction to the external pipe 7, which can restrict the flow direction of the dosing pipe 8 and prevent backflow due to high pressure in the external pipe 7.

[0037] In addition, the outer pipe 7 includes a straight section 71, an inclined section 72, and a straight section 73 connected in sequence. The straight section 71 and the straight section 73 are horizontal, while the inclined section 72 is inclined. The straight section 73 is positioned higher than the straight section 71, and the inclined section 72 forms an inclined transition between the straight section 71 and the straight section 73.

[0038] The first straight section 71 is connected to the second end 62 of the vent pipe, and the dosing pipe 8 is connected to the upper side of the first straight section 71; the second straight section 73 is connected to the external air source. By adopting a high structural design, it is possible to avoid the reagent flowing back to the external air source along the external pipe 7 during the dosing process, ensuring that the added reagent can enter the water washing container 1, and will not cause unnecessary pollution or damage to the external air source.

[0039] The reagent added from the dosing pipe 8 needs to flow downwards through the vent pipe 6, passing through the first end 61 of the vent pipe before entering the washing container 1. When the reagent passes through the first end 61 of the vent pipe, it can react with the sewage and silt in the first end 61 of the vent pipe. Moreover, the concentration is relatively high at this time, and the reaction efficiency is also higher. To a certain extent, this can help to clear and prevent blockage of the first end 61 of the vent pipe.

[0040] Furthermore, a baffle plate 5 is fixedly connected to the inner wall of the washing container 1. The baffle plate 5 is located at the lower inner part of the drain outlet 41 and above the second end 22 of the inlet pipe. The baffle plate 5 can create a separation between the drain outlet 41 and the second end 22 of the inlet pipe, preventing water from the second end 22 of the inlet pipe from directly entering the drain outlet 41.

[0041] The baffle plate 5 is inclined, gradually rising in the direction away from the drain outlet 41, and the highest point of the baffle plate 5 is higher than the drain outlet 41. The baffle plate 5 can form a barrier on the inside of the drain outlet 41, reducing the discharge of sand and gravel particles from the bottom of the drain outlet 41. Moreover, a groove-shaped space is formed between the baffle plate 5 and the inner wall of the washing container 1, and an activated carbon granular bag is placed in this groove-shaped space to supplement the filtration effect.

[0042] This embodiment is mainly used to treat wastewater containing particulate matter. The particulate matter in the wastewater is confined to the bottom of the washing container 1 by gravity. The components of the particulate matter in the wastewater are washed by adding reagents into the washing container 1, and the impurities in the particulate matter are removed by reaction.

[0043] During operation, wastewater containing a large amount of particulate impurities is introduced into the washing container 1 through the inlet pipe 2. Treatment agents are added to the washing container 1 through the dosing pipe 8 and the sludge discharge pipe 3 to treat the wastewater and the particulate matter in it. To facilitate the aggregation of particulate matter, a flocculant can also be mixed into the treatment agents.

[0044] During the treatment process, the washing container 1 needs to be allowed to stand to allow the liquid and solid matter inside to separate, with the solid matter settling at the bottom. The relatively clean wastewater at the top can then be discharged through the drain pipe 4; the bottom layer forms the sediment layer 100. Alternatively, sand and gravel particles can be added to the washing container 1 before use to pre-form the sediment layer 100, creating a base bed that facilitates the subsequent accumulation of particles at the bottom. The relatively large size of the sand and gravel particles helps prevent the final sediment layer 100 from being too dense.

[0045] Aeration is periodically carried out through the slag discharge pipe 3 to the bottom of the washing container 1. During the aeration process, the sediment layer 100 in the washing container 1 can be stirred, avoiding the blockage caused by long-term sedimentation.

[0046] This embodiment also discloses a wastewater purification system, including an independent water washing treatment device as described in the above embodiment, which can purify wastewater, especially treating solid impurities mixed in it.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
