Description

Technical Field

[0001] This utility model relates to the field of multi-stage purification technology for bottled water, and in particular to a multi-stage purification device for bottled water production. Background Technology

[0002] The multi-stage purification system for bottled water production typically includes the following purification processes: Coarse filtration: Removes larger particulate impurities from the water, such as silt and suspended solids. Activated carbon filtration: Utilizes the adsorption properties of activated carbon to remove organic matter, residual chlorine, odors, and some heavy metals from the water. Fine filtration: Further removes tiny particles and bacteria from the water, ensuring clear and transparent water quality. Reverse osmosis: Through semi-permeable membrane filtration, removes dissolved salts, bacteria, viruses, and other minute substances from the water, achieving pure water standards. Post-treatment: Includes ultraviolet sterilization and ozone sterilization to ensure the hygiene and safety of the bottled water. Mineralization treatment: Depending on the needs, appropriate amounts of minerals may be added to improve the taste and nutritional value of the water. Bottling: The purified water is filled into bottles in a sterile environment, completing the production process.

[0003] In bottled water production, multi-stage purification systems, where each filter layer is independently located within the tank and transported via pipelines, result in a relatively slow filtration process. Water must pass through different filter layers sequentially at each stage, which not only prolongs the water's residence time within the system but may also increase its transit time in the pipelines due to the physical distance between the filter layers. While this design ensures water purification quality, it reduces overall processing efficiency, thus impacting production speed and output. Utility Model Content

[0004] The main objective of this invention is to provide a multi-stage purification device for bottled water production, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-stage purification device for bottled water production includes a first purification tank, an inlet pipe, and a first valve. The inlet pipe is connected to the side wall of the first purification tank, and the first valve is installed on the inlet pipe to control the opening and closing of the inlet pipe.

[0007] The first purification tank has a first purification filter layer, a second purification filter layer and a third purification filter layer arranged from top to bottom. The first purification filter layer, the second purification filter layer and the third purification filter layer realize multi-layer filtration and purification operation in the production of bottled water.

[0008] On the other side of the first purification tank, there are a first drain pipe, a second drain pipe, and a third drain pipe that correspond to the first purification filter layer, the second purification filter layer, and the third purification filter layer in sequence. Each of the first drain pipe, the second drain pipe, and the third drain pipe is equipped with a second valve.

[0009] A second purification tank is located next to the first purification tank, and a third purification tank is located next to the second purification tank. The first, second, and third purification tanks are connected by a drain pipe and are opened and closed by a second valve.

[0010] As an optional solution of this application, the lower ends of the first purification tank, the second purification tank, and the third purification tank are connected to backwash pumps, the other end of the backwash pumps are connected to cleaning liquid pipelines, and the upper side walls of the first purification tank, the second purification tank, and the third purification tank are connected to sewage pipes. The backwash pumps are used to backwash the different filter purification layers in the purification tanks, and the backwash wastewater is discharged from the sewage pipes.

[0011] As an optional solution of this application, the first purification filtration layer is a grid filter or a sand filter, the second purification filtration layer is a filter screen or a ceramic filter screen, and the third purification filtration layer is an activated carbon filter screen.

[0012] As an optional solution of this application, the first drain pipe, the second drain pipe, the third drain pipe and the second valve are connected by connecting flanges, bolts and nuts;

The sealing sleeve is designed in a circular shape, and a sealing ring is fitted on the outer wall of the circular sealing sleeve. The sealing sleeve is fixed to the purification tank by bolts.

[0014] As an optional solution to this application, the first drainage pipe, the second drainage pipe, and the third drainage pipe may be used individually or in combination.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Three different purification filtration layers (bar filter and sand filter, filter screen and ceramic filter, activated carbon filter) sequentially remove suspended solids, organic matter, microorganisms, and other impurities from the water, ensuring that the water quality meets standards. The drainage pipes facilitate effective drainage from each purification layer, guaranteeing the continuity and efficiency of the purification process.

[0017] A backwash pump delivers cleaning fluid to each purification tank, achieving backwashing and effectively removing impurities from the filter layer, thus extending its service life. Wastewater generated during backwashing is discharged through a drain pipe, ensuring the system's cleanliness and purification effectiveness. After backwashing, the system quickly returns to normal filtration status, ensuring stable operation of the purification system. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, a multi-stage purification device for bottled water production includes a first purification tank 1, a water inlet pipe 2, and a first valve 3. The water inlet pipe 2 is designed to be connected to the side wall of the first purification tank 1, while the first valve 3 is installed on the water inlet pipe 2. Its main function is to control the opening and closing operation of the water inlet pipe 2 to ensure that the water flow and pressure meet the purification requirements.

[0025] Inside the first purification tank 1, three purification filtration layers are arranged from top to bottom: the first purification filtration layer 10, the second purification filtration layer 11, and the third purification filtration layer 12. These filtration layers work together through their respective filtration mechanisms to achieve multi-layer filtration and purification in the bottled water production process, thereby ensuring that the water quality meets the standards.

[0026] To facilitate drainage operations for different purification layers, the other side of the first purification tank 1 is equipped with a first drainage pipe 6, a second drainage pipe 7, and a third drainage pipe 8, corresponding sequentially to the first purification filter layer 10, the second purification filter layer 11, and the third purification filter layer 12. Each of these drainage pipes is equipped with a second valve 9 to control the timing and amount of drainage.

[0027] In addition, this device also includes a second purification tank 4 and a third purification tank 5, which are located next to the first purification tank 1 and the second purification tank 4, respectively. These three purification tanks are interconnected through drainage pipes and are opened and closed through a second valve 9 to ensure the continuity and efficiency of the entire purification system.

[0028] To further improve the purification effect, a backwash pump 13 is connected to the lower end of the first purification tank 1, the second purification tank 4, and the third purification tank 5. The other end of the backwash pump 13 is connected to a cleaning fluid pipeline for backwashing the different filter layers inside the purification tanks to remove impurities from the filter layers. A drain pipe 14 is connected to the upper side wall of the first purification tank 1, the second purification tank 4, and the third purification tank 5, and the wastewater generated during backwashing will be discharged through the drain pipe 14.

[0029] In terms of the specific implementation of the filtration layers, the first purification filtration layer 10 is designed as a bar screen filter and a sand filter, the second purification filtration layer 11 is a filter screen and a ceramic filter screen, and the third purification filtration layer 12 is an activated carbon filter screen. The combination of these filtration layers can effectively remove impurities such as suspended solids, organic matter, and microorganisms from the water.

[0030] To ensure the stability and sealing of the drainage pipeline connections, the first drainage pipeline 6, the second drainage pipeline 7, the third drainage pipeline 8, and the second valve 9 are connected via flanges, bolts, and nuts. This connection method not only ensures the robustness of the pipelines but also facilitates maintenance and replacement.

[0031] To further enhance the fixation effect of the filter layers, the first purification filter layer 10, the second purification filter layer 11, and the third purification filter layer 12 are fixed inside the purification tank by sealing sleeves. These sealing sleeves are designed in a circular shape, with sealing rings fitted on their outer walls, and are fixed to the purification tank by bolts, thereby ensuring the stability and sealing of the filter layers.

[0032] Finally, the first drain pipe 6, the second drain pipe 7, and the third drain pipe 8 can be used individually or combined as needed to adapt to different production requirements and operating conditions.

[0033] Operating Procedure: Open the first valve 3 to allow water to enter the first purification tank 1 through the inlet pipe 2. The water undergoes multi-stage filtration from top to bottom, passing through the first purification filter layer 10, the second purification filter layer 11, and the third purification filter layer 12. The purified water flows out from the bottom of the first purification tank 1 and enters subsequent purification tanks (second purification tank 4 and third purification tank 5) for further treatment. Depending on production needs, the first drain pipe 6, the second drain pipe 7, and the third drain pipe 8 can be used individually or in combination for drainage. The timing and amount of drainage are controlled by the second valve 9 to ensure purification effectiveness and system efficiency.

[0034] Backwashing process: Start backwash pump 13 to deliver cleaning solution to the first purification tank 1, second purification tank 4, and third purification tank 5 through the cleaning solution delivery pipeline. The cleaning solution passes through the third purification filter layer 12, the second purification filter layer 11, and the first purification filter layer 10 sequentially from bottom to top for backwashing. During backwashing, impurities and contaminants are carried out of the filter layers by the cleaning solution and discharged through the drain pipe 14 connected to the upper side wall of the first purification tank 1, the second purification tank 4, and the third purification tank 5. After backwashing is completed, shut off backwash pump 13 and related valves to ensure the system returns to normal filtration status.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
