Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a water purification equipment based on non-powered sedimentation technology. Background Technology

[0002] In remote areas, rural settlements, and temporary construction sites where municipal water supply coverage is insufficient, water purification equipment is a core facility for ensuring drinking water safety and compliant production water use. Currently, in such scenarios, water purification equipment utilizes fiber filters, which use the retention effect of the fiber filter media to purify the water. Due to their relatively simple structure and low initial investment, these filters are widely used in small and medium-sized water supply systems, such as more integrated containerized water supply stations. Especially when treating water sources containing a certain amount of suspended solids, fiber filters can remove some impurities from the water through the adsorption and sieving effects of the filter media, providing a basic guarantee for subsequent water use.

[0003] However, existing water purification equipment based on fiber filters has obvious technical limitations: it lacks pre-filtration methods, which easily leads to large particles clogging the filter cartridges, requiring frequent disassembly and replacement of fiber filter media cartridges. This not only increases the labor intensity of operation and maintenance, but also results in high purification costs due to the continuous consumption of filter media consumables; the purification effect is relatively simple, only able to play a limited role in intercepting visible suspended solids with larger particle sizes in the water, and the treatment effect is poor for complex water sources such as groundwater with high concentrations of silt. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a water purification and supply device based on non-powered sedimentation technology, so as to solve the technical problems of existing water purification and supply devices with fiber filters as the core lacking pre-filtration means, being prone to frequent replacement of filter media due to large particles, having high maintenance costs, having single purification function, and being ineffective in treating complex water sources containing high concentrations of silt.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A water purification and supply device based on non-powered sedimentation technology includes a fiber filter tank. An inlet pipe and an outlet pipe are respectively arranged vertically on one side of the fiber filter tank, and both are connected to the fiber filter tank. A non-powered sedimentation assembly is located in the upper part of the fiber filter tank. A perforated plate is located below the fiber filter tank, and a grid plate is located at the bottom of the perforated plate. A pressure ring is located at the top of the perforated plate, and the grid plate is located above the outlet pipe. A drain pipe is located at the bottom of the fiber filter tank.

[0007] As an improved technical solution, the non-powered sedimentation assembly includes a fixed base, which is fixedly installed inside the fiber filter tank and located below the water inlet pipe. The top of the fixed base is provided with a second partition and a first partition, respectively. A bent pipe is installed through the first partition and the second partition. The bottom of the fixed base is provided with a water distribution pipe, and a plurality of water outlet holes are opened at the bottom of one end of the water distribution pipe. One end of the water distribution pipe extends to the outside of the fiber filter tank and communicates with the part of the fiber filter tank located above the fixed base.

[0008] As an improved technical solution, the bent pipes installed on the first and second partitions are staggered vertically, and the bent pipes have a Z-shaped structure. The top of the fiber filter tank is symmetrically provided with lifting lugs.

[0009] As an improved technical solution, the fiber filter tank has several discharge pipes on the back, and the discharge pipes are connected to the space between partition one and partition two and on both sides. The top of the fixed base has an inclined surface, and the inclined surface is inclined towards the direction of the discharge pipe.

[0010] As an improved technical solution, a manhole flange is provided on one side of the fiber filter tank, and a manhole cover is connected to one end of the manhole flange. An observation window is provided on the manhole cover.

[0011] As an improved technical solution, a coarse filter is connected to one side of the fiber filter tank via a pipe, a security filter is connected to the side of the fiber filter tank away from the coarse filter, and RO membrane module one and RO membrane module two are sequentially connected to the side of the security filter via pipes.

[0012] As an improved technical solution, a scale inhibitor tank and a metering pump are provided on one side of the fiber filter tank, and the input end of the metering pump is connected to the scale inhibitor tank. The scale inhibitor tank and the metering pump are connected to the fiber filter tank and the security filter respectively through pipelines.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. This utility model achieves pre-sedimentation and separation of particulate matter in water sources containing high concentrations of silt and sand through a non-powered sedimentation component, reducing the clogging of the filter media in the fiber filter tank by large particles, reducing the frequency of filter media replacement and maintenance labor intensity, and significantly saving purification costs.

[0014] 2.

[0025] like Figures 1 to 5 As shown in the figure, this embodiment provides a water purification and supply device based on non-powered sedimentation technology, including a fiber filter tank 1. An inlet pipe 6 and an outlet pipe 7 are respectively distributed vertically on one side of the fiber filter tank 1, and both the inlet pipe 6 and the outlet pipe 7 are connected to the fiber filter tank 1. A non-powered sedimentation assembly is provided in the upper part of the fiber filter tank 1. A perforated plate 14 is provided below the fiber filter tank 1, and a grid plate 16 is provided at the bottom of the perforated plate 14. A pressure ring 15 is provided at the top of the perforated plate 14. The grid plate 16 is located above the outlet pipe 7. A drain pipe 5 is provided at the bottom of the fiber filter tank 1. The drain pipe 5 can promptly discharge the settled impurities, preventing impurity accumulation from affecting the equipment's operating efficiency. Simultaneously, the combined design of the perforated plate 14, the grid plate 16, and the pressure ring 15 can stably support the filter media structure, prevent filter media loss, and ensure filtration stability.

[0026] In this example, the non-powered sedimentation assembly includes a fixed base 8, which is fixedly installed inside the fiber filter tank 1 and located below the inlet pipe 6. The top left and right sides of the fixed base 8 are respectively provided with a second partition 10 and a first partition 9. A bent pipe 11 is installed through the first partition 9 and the second partition 10. The bottom of the fixed base 8 is provided with a water distribution pipe 13, and several water outlet holes are opened at one end of the water distribution pipe 13. One end of the water distribution pipe 13 extends to the outside of the fiber filter tank 1 and communicates with the part of the fiber filter tank 1 located above the fixed base 8. The fixed base 8, together with the first partition 9 and the second partition 10, forms a multi-segment sedimentation space. The design of the water outlet holes of the water distribution pipe 13 achieves uniform water distribution, avoids local filter media overload, and further improves filtration efficiency and water quality stability.

[0027] In this example, the bent pipes 11 installed on the first partition 9 and the second partition 10 are staggered vertically, and the bent pipes 11 have a Z-shaped structure. The top of the fiber filter tank 1 is symmetrically provided with lifting lugs 2. The staggered vertical distribution of the bent pipes 11 can avoid water flow short circuits, ensure that each section of space can fully play the sedimentation role, and improve the impurity removal rate. The lifting lugs 2 facilitate the hoisting, transportation, installation and maintenance of the equipment, and are suitable for the flexible deployment needs of remote areas and temporary construction sites.

[0028] In this example, the fiber filter tank 1 has several discharge pipes 12 on its back, and the discharge pipes 12 are connected to the space between the partition 9 and the partition 10 and on both sides. The top of the fixed base 8 is provided with an inclined surface 17, which is inclined towards the direction of the discharge pipes 12. In this example, the discharge pipes 12 are opened when the equipment is not in use to allow the mud and sand inside to be discharged naturally or by pumping. The inclined surface 17 guides the settled mud and sand to converge towards the discharge pipes 12, and works with the discharge pipes 12 to achieve segmented sewage discharge, reduce secondary pollution from settled impurities, and can also discharge sewage in a targeted manner according to the impurity accumulation in different sedimentation spaces, thereby improving sewage discharge efficiency and equipment cleanliness.

[0029] In this example, a manhole flange is provided on one side of the fiber filter tank 1, and a manhole cover 3 is connected to one end of the manhole flange. An observation window 4 is provided on the manhole cover 3. The manhole cover 3 facilitates the operation of personnel to enter the fiber filter tank 1 for inspection, filter media replacement and other maintenance work. The observation window 4 allows real-time observation of the sedimentation and filtration in the tank, enabling the operator to monitor the equipment's operating status without stopping the machine, thereby reducing maintenance costs and downtime losses.

[0030] In this example, a coarse filter 18 is connected to one side of the fiber filter tank 1 via a pipe, and a security filter 21 is connected to the side of the fiber filter tank 1 away from the coarse filter 18. RO membrane module 1 22 and RO membrane module 23 are sequentially connected to one side of the security filter 21 via pipes. The coarse filter 18 performs pre-filtration, further intercepting large-particle impurities and reducing the processing load on the non-powered sedimentation components and the fiber filter tank 1. The security filter 21 filters fine suspended solids and colloids, protecting the subsequent RO membrane modules 1 22 and RO membrane module 23 from contamination and clogging, extending the service life of the RO membranes. The multi-stage filtration combination significantly improves the purification effect on complex water sources, ensuring that the effluent water quality meets drinking water or industrial water standards.

[0031] In this example, a scale inhibitor tank 19 and a metering pump 20 are provided on one side of the fiber filter tank 1, and the input end of the metering pump 20 is connected to the scale inhibitor tank 19. The scale inhibitor tank 19 and the metering pump 20 are connected to the fiber filter tank 1 and the security filter 21 respectively through pipelines. The metering pump 20 can accurately control the dosage of scale inhibitor, avoiding waste or insufficient dosage of scale inhibitor. The scale inhibitor can effectively prevent scale formation on the surface of the fiber filter media and RO membrane, ensure the stable operation of the filtration and reverse osmosis system, reduce the frequency of equipment cleaning and maintenance costs, and improve the continuous operation capability of the overall water supply system.

[0032] During use, the water source first undergoes primary filtration through the coarse filter 18 to intercept large-diameter impurities, and then enters the fiber filter tank 1 through the inlet pipe 6. It flows into the right-side space above the fixed seat 8, which is divided by the partition 9, and starts the non-powered sedimentation process.

[0033] The water flows naturally into the space on the right. Large particles of silt and other impurities settle on the inclined surface 17 at the top of the fixed seat 8 under the action of gravity. The upper layer of clear water enters the space between the first partition 9 and the second partition 10 through the Z-shaped bend 11 on the first partition 9. After settling again, the upper layer of clear water flows into the space on the left side of the second partition 10 through the staggered bend 11 on the second partition 10, realizing multi-stage non-powered sedimentation. The settled impurities can be discharged in sections through the discharge pipe 12.

[0034] The clean water in the space on the left side of partition 2 10 enters the water distribution pipe 13 and is evenly distributed to the fiber filter material layer below the fixed seat 8 through several water outlet holes at the bottom of the water distribution pipe 13. After being adsorbed and filtered by the fiber filter material, it is further filtered through the grid plate 16 and finally discharged through the water outlet pipe 7.

[0035] After preliminary purification, the water enters the security filter 21, where fine suspended solids and colloids are filtered out. Then, it flows through RO membrane module 1 22 and RO membrane module 23 for deep reverse osmosis treatment. At the same time, the scale inhibitor in the scale inhibitor tank 19 is precisely added to the fiber filter tank 1 and the security filter 21 through the metering pump 20 to prevent scale formation on the filter media and RO membrane.

[0036] During equipment operation, the drain pipe 5 at the bottom of the fiber filter tank 1 can promptly discharge the impurities deposited inside the tank. Operators can monitor the operating status inside the tank in real time through the observation window 4 on the manhole cover 3. If maintenance is required, the operator can enter the tank through the manhole cover 3. The lifting lug 2 facilitates the overall hoisting and deployment of the equipment.

[0037] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
