Description

Technical Field

[0001] This utility model relates to the field of water supply filtration technology, and in particular to a water supply filtration device. Background Technology

[0002] In today's society, water, as an indispensable resource, plays a vital role in all sectors. Whether it's drinking and washing in daily life, cooling and processing in industrial production, or concrete mixing and dust suppression in construction, water is indispensable. However, natural water sources often contain various impurities, which can cause serious damage to water-using equipment and systems. Therefore, effective filtration of water sources is particularly important.

[0003] In existing water supply filtration systems, especially for construction water, filtration devices frequently face the problem of clogging by large impurities. Traditional filtration devices have relatively simple structural designs, mostly using a simple single or double-layer filter screen. This approach may meet basic filtration needs for small amounts of impurities, but as usage time increases, impurities gradually accumulate on the filter screen. These accumulated impurities severely obstruct water flow, leading to poor water flow and significantly reducing the efficiency of the entire water supply system. For example, in construction, poor water flow directly affects the quality and efficiency of concrete mixing, thus impacting the progress of the entire project.

[0004] Furthermore, in traditional filtration devices, the contact between the water flow and the filter screen is insufficient during the filtration process, resulting in poor filtration efficiency. Because the filter screen is stationary, the water flow often only passes through a localized area of ​​the screen, leading to overuse of some areas while other areas are underutilized, further reducing filtration efficiency. To address these issues, we propose a water supply filtration device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water supply filtration device.

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

[0007] A water supply filtration device includes a first conical conveying cylinder and a second conical conveying cylinder. An input structure is connected to one side of the upper end of the first conical conveying cylinder. Spiral guide plates are provided at equal intervals on the inner sidewall of the first conical conveying cylinder. A diffusion structure is connected to one side of the lower end of the first conical conveying cylinder. One end of the diffusion structure is connected to one side of the middle of the second conical conveying cylinder. A first conical filter screen is rotatably connected inside the second conical conveying cylinder. A second conical filter screen is elastically sleeved inside the first conical filter screen. A brush layer is provided on the inner sidewall of the second conical filter screen, and the brush layer corresponds to the inner sidewall of the first conical conveying cylinder.

[0008] Preferably, the input structure includes an input pipe connected to one side of the upper end of the first conical conveying cylinder, and an output pipe connected to one side of the middle part of the second conical conveying cylinder.

[0009] Preferably, the diffusion structure includes a connecting pipe connected to one side of the lower end of the first conical conveying cylinder, one end of the connecting pipe being connected to an expansion joint, and one end of the expansion joint being connected to the middle side wall of the second conical conveying cylinder.

[0010] Preferably, a first connecting rod is fixed to the lower end of the first conical filter screen, and the lower end of the first connecting rod is rotatably connected to the bottom of the second conical conveying cylinder. Multiple turbine blades are installed at equal intervals on the circumferential sidewall of the first conical filter screen.

[0011] Preferably, the upper ends of both the first and second conical conveying cylinders are detachably fitted with sealing caps, and the lower end of the first conical conveying cylinder is fixed with a pad.

[0012] Preferably, springs are connected to both the upper and lower ends of the second conical filter screen. A second connecting rod is sleeved on one end of the spring. A baffle is fixedly sleeved on the circumference of the second connecting rod, and one side of the spring abuts against one end of the baffle. One end of one of the second connecting rods is rotatably connected to the bottom of the first conical conveying cylinder, and the other second connecting rod is rotatably connected to the lower end of the sealing cover.

[0013] In this utility model:

[0014] Spiral guide plates are evenly spaced on the inner side wall of the first conical conveying cylinder. Water is input from the upper side of the first conical conveying cylinder and output from the lower side. The spiral guide plates can guide the water flow in a spiral shape, increase the residence time of the water in the conveying cylinder, make the water flow more evenly distributed, and at the same time help to initially separate and settle larger impurities at the bottom of the conveying cylinder.

[0015] The output end of the first conical conveying cylinder is connected to the second conical conveying cylinder through the expansion joint and connecting pipe of the expansion pipeline. The function of the expansion pipeline is to smoothly introduce the water flow that has been pre-treated by the first conical conveying cylinder into the second conical conveying cylinder.

[0016] The second conical conveying cylinder is equipped with a first conical filter screen. Turbine blades are provided on the circumference of the side wall of the first conical filter screen. When water flows into the second conical conveying cylinder, the impact force of the water flow will drive the turbine blades to rotate, thereby causing the first conical filter screen to rotate as well. This rotation method can make the water flow more fully contact the filter screen and improve the filtration effect.

[0017] The first conical filter screen contains a second conical filter screen, with springs connecting both its upper and lower ends. When the first conical filter screen rotates, the second conical filter screen vibrates stably up and down via the springs and the first and second connecting rods. Simultaneously, a brush layer is installed on the circumference of the second conical filter screen. As the second conical filter screen vibrates up and down, the brush layer continuously cleans the inner wall of the first conical filter screen, preventing impurities from accumulating on the screen and effectively preventing both conical filters from clogging.

[0018] This utility model has the following advantages:

[0019] 1. By setting a spiral guide plate inside the first conical conveying cylinder, the water flow is pre-treated to make the water flow more uniform and separate larger impurities.

[0020] 2. The first conical filter screen inside the second conical conveying cylinder rotates through turbine blades, improving the filtration effect;

[0021] 3. The second conical filter screen vibrates up and down through a spring and uses a brush to clean the inner wall of the first conical filter screen, which effectively prevents the filter screen from clogging, extends the service life of the filter screen, and reduces maintenance costs.

[0022] In summary, the filtration device of this invention, through the initial separation of large impurities and combined with the rotation of the filter, ensures full contact between the water source and the filter screen, greatly improving the filtration effect. At the same time, it increases the contact area of ​​the water body, enhances the filtration speed, and can also clean the filter screen through the vibration of the brush, preventing filter screen blockage, extending the service life of the filter screen, and reducing maintenance costs.

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1-6 A water supply filtration device includes a first conical conveying cylinder 7 and a second conical conveying cylinder 3. An input structure is connected to one side of the upper end of the first conical conveying cylinder 7. Spiral guide plates 9 are provided at equal intervals on the circumferential side wall inside the first conical conveying cylinder 7. This spiral flow pattern can increase the residence time of water in the conveying cylinder. During the spiral descent of the water, the speed and direction of the water flow change continuously, making the water flow more evenly distributed in the conveying cylinder. At the same time, this flow pattern helps to initially separate larger impurities.

[0032] A diffusion structure is connected to one side of the lower end of the first conical conveying cylinder 7. One end of the diffusion structure is connected to one side of the middle part of the second conical conveying cylinder 3. A first conical filter screen 10 is rotatably connected inside the second conical conveying cylinder 3. A second conical filter screen 17 is elastically sleeved inside the first conical filter screen 10. A brush layer 16 is provided on one circumference of the side wall of the second conical filter screen 17. The brush layer 16 corresponds to one circumference of the side wall inside the first conical conveying cylinder 7.

[0033] The input structure includes an input pipe 8 connected to one side of the upper end of the first conical conveying cylinder 7, and an output pipe 1 connected to one side of the middle part of the second conical conveying cylinder 3. The input pipe 8 is made of stainless steel or engineering plastic to ensure that the input pipe 8 will not leak or be damaged during long-term use.

[0034] The diffusion structure includes a connecting pipe 5 connected to one side of the lower end of the first conical conveying cylinder 7. One end of the connecting pipe 5 is connected to an expansion joint 4. One end of the expansion joint 4 is connected to the middle side wall of the second conical conveying cylinder 3. The expansion joint 4 plays a key role in smoothly introducing water into the second conical conveying cylinder 3. The expansion structure of the expansion joint 4 can prevent excessive water flow impact or uneven distribution when the water enters the second conical conveying cylinder 3, ensuring that the water can smoothly enter the next filtration stage.

[0035] The lower end of the first conical filter screen 10 is fixed with a first connecting rod 12. The lower end of the first connecting rod 12 is rotatably connected to the bottom of the second conical conveying cylinder 3. Multiple turbine blades 11 are installed at equal intervals on the side wall of the first conical filter screen 10. When water flows into the second conical conveying cylinder 3, the impact force of the water flow will act on the turbine blades 11, causing the turbine blades 11 to rotate, thereby causing the first conical filter screen 10 to rotate as well. This allows the water flow to come into more full contact with the filter screen, improving the filtration effect. Compared with traditional fixed filter screens, rotating filter screens can prevent water flow from passing through only a local area of ​​the filter screen, allowing the entire filter screen to play a filtration role, thus more effectively intercepting impurities in the water.

[0036] Both the upper ends of the first conical conveying cylinder 7 and the second conical conveying cylinder 3 are detachably fitted with sealing caps 2. A pad 6 is fixed to the lower end of the first conical conveying cylinder 7. Springs 13 are connected to both the upper and lower ends of the second conical filter screen 17. A second connecting rod 15 is sleeved on one end of each spring 13. A baffle 14 is fixedly fitted onto the circumference of the second connecting rod 15, and one side of the spring 13 abuts against one end of the baffle 14. One end of one second connecting rod 15 is rotatably connected to the bottom of the first conical conveying cylinder 7, and the other second connecting rod 15 is rotatably connected to... At the lower end of the sealing cover 2, when the first conical filter screen 10 rotates, due to the elastic action of the spring 13, the second conical filter screen 17 will achieve stable up-and-down vibration through the spring 13 and the second connecting rod 15. At the same time, the brush layer 16 on the side wall of the second conical filter screen 17 will continuously vibrate and clean the inner wall of the first conical filter screen 10, which can remove impurities attached to the inner wall of the first conical filter screen 10 in time, avoid impurities from accumulating on the filter screen, thereby effectively preventing the two conical filter screens from clogging and ensuring the continuous and stable operation of the filtration device.

[0037] In this utility model:

[0038] Spiral guide plates 9 are evenly spaced on the inner side wall of the first conical conveying cylinder 7. Water is input from the upper side of the first conical conveying cylinder 7 and output from the lower side. The spiral guide plates 9 can guide the water flow in a spiral shape, increase the residence time of the water in the conveying cylinder, make the water flow more evenly distributed, and at the same time help to initially separate and settle larger impurities at the bottom of the conveying cylinder.

[0039] The output end of the first conical conveying cylinder 7 is connected to the second conical conveying cylinder 3 through the expansion joint 4 and the connecting pipe 5 of the expansion pipe. The function of the expansion pipe is to smoothly introduce the water flow that has been pre-treated by the first conical conveying cylinder 7 into the second conical conveying cylinder 3.

[0040] The second conical conveying cylinder 3 is equipped with a first conical filter screen 10. Turbine blades 11 are provided on the circumferential side wall of the first conical filter screen 10. When water flows into the second conical conveying cylinder 3, the impact force of the water flow will drive the turbine blades 11 to rotate, thereby causing the first conical filter screen 10 to rotate as well. This rotation method can make the water flow more fully contact the filter screen and improve the filtration effect.

[0041] The first conical filter screen 10 contains a second conical filter screen 17, with springs 13 connected to both the upper and lower ends of the second conical filter screen 17. When the first conical filter screen 10 rotates, the second conical filter screen 17 achieves stable up-and-down vibration through the springs 13, the first connecting rod 12, and the second connecting rod 15. At the same time, a brush layer 16 is provided on the circumferential side wall of the second conical filter screen 17. When the second conical filter screen 17 vibrates up and down, the brush layer 16 continuously cleans the inner wall of the first conical filter screen 10, preventing impurities from accumulating on the filter screen and effectively preventing the two conical filters from clogging.

[0042] 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.
