Description

Technical Field

[0001] The present invention relates to the technical field of sewage filtration, and in particular to a water inlet culvert filtration device and method. Background Art

[0002] In many industrial and civil fields, filtering and purifying water sources is an essential link. Traditional filtration devices mostly use static filter nets or filter elements for filtration. Although this method is simple and effective, it has some shortcomings during use. For example, the filter net is easily clogged by impurities, resulting in a decrease in the water flow capacity; in addition, the filter net needs to be cleaned or replaced regularly during the filtration process, which not only increases maintenance costs, but also affects the working efficiency of the equipment. In addition, traditional filtration devices often do not have a self-cleaning function and require manual intervention after shutdown to remove accumulated impurities.

[0003] In recent years, with the development of technology, some filtration devices with automatic cleaning functions have appeared on the market. They make the filtration process more efficient and easy to maintain through the design of mechanical structure. However, these devices are usually complex in structure, high in cost, and limited in application in certain specific environments (such as underwater environments). Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a water inlet culvert filter device. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A water inlet culvert filter device comprises a base, a water filter cartridge, a rotating shaft and a plurality of driving devices, wherein two bases are provided and are arranged in a cylindrical shape, the water filter cartridge is rotatably installed in the two bases and is arranged obliquely, filter holes are evenly opened on the water filter cartridge, the rotating shaft is arranged concentrically with the water filter cartridge, a spiral blade is fixedly connected to the rotating shaft, the spiral blade is tangent to the inner wall of the water filter cartridge, both ends of the rotating shaft are fixedly connected to a rotating drum frame, the rotating drum frame is rotatably connected to the base, and two driving devices are provided and respectively drive the rotating shaft and the water filter cartridge to rotate in the base.

[0005] Furthermore, each base is rotatably connected to a ring gear, the inner and outer walls of the ring gear are provided with teeth, both ends of the outer wall of the water filter cartridge are fixedly connected to ring gears, the ring gears cooperate with the inner teeth of the ring gears, and a driving device meshes with the ring gears.

[0006] Furthermore, an annular limiting groove is fixedly connected in the base, and the drum frame is rotatably installed in the limiting groove via a bearing.

[0007] Furthermore, a special-shaped cylinder is hingedly connected to the lower end of the rotating shaft and a stopper is fixedly connected to limit the special-shaped cylinder. The upper part of the special-shaped cylinder is arranged to be conical, and the lower part of the special-shaped cylinder is open and faces the water filter cylinder. The stopper is inclined to limit the rotation angle of the special-shaped cylinder toward the lower end of the base.

[0008] Furthermore, the upper portion of the special-shaped cylinder close to the end surface of the water filter cylinder is arranged as a filter screen.

[0009] Furthermore, the rotation direction of the water filter cartridge is opposite to the rotation direction of the spiral blades, and the rotation of the spiral blades lifts the debris entering the water filter cartridge to a higher position in the water filter cartridge.

[0010] Furthermore, the rotation direction of the water filter cartridge is the same as that of the spiral blades. The rotation of the spiral blades lifts the debris entering the water filter cartridge to a higher position in the water filter cartridge. The rotation speed of the spiral blades is higher than that of the water filter cartridge.

[0011] Furthermore, a feed discharge port is provided on the base located at a high position, and the feed discharge port is located at the end of the water filter cartridge.

[0012] Furthermore, the lower end of the water filter cartridge is fixedly connected with a conical bag material cartridge.

According to the amount of impurities in the water flow, the rotation direction and speed of the water filter cartridge and the spiral blade are adjusted to achieve the best filtering effect. When the two rotate in opposite directions, the spiral blade will quickly lift the impurities entering the water filter cartridge to a high position in the water filter cartridge. When the two rotate in the same direction, the rotation speed of the spiral blade is higher than that of the water filter cartridge, so that the impurities entering the water filter cartridge are crushed and lifted to a high position in the water filter cartridge. S5. When the water inflow of the water filter cylinder is large, the water flow impacts the filter screen of the special-shaped cylinder, and the debris filtered by the filter screen falls on the impact water flow at the lower part of the special-shaped cylinder, so as to bring the debris to the position near the middle of the water filter cylinder, so as to facilitate the spiral blades to lift the debris. When the water inflow of the water filter cylinder is small, the water flow falls on the bottom surface of the upper part of the special-shaped cylinder opposite to the filter screen. Under the action of continuous water flow, the special-shaped cylinder deviates at a certain angle, so that the lower part of the special-shaped cylinder throws the water flow into the position near the middle of the water filter cylinder, so as to facilitate the spiral blades to lift the debris; S6. Use a filter cartridge to prevent debris from falling into the water filter cartridge.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Due to the inclined setting of the water filter cartridge and the design of the spiral blades, the suspended matter in the water can be effectively separated, ensuring the filtration efficiency while reducing the risk of clogging and achieving efficient filtration; 2.

Since the device adopts a more universal design, it can be used in a variety of environments, whether it is industrial water or domestic water treatment. Through optimized design, unnecessary energy consumption is reduced, making the entire filtration process more energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Please refer to Figure 1 As shown, a water inlet culvert filtering device includes a base 1, a water filter cartridge 2, a rotating shaft 3 and a plurality of driving devices 4, wherein the base 1 is provided with two and is arranged in a cylindrical shape, the water filter cartridge 2 is rotatably installed in the two bases 1 and is arranged obliquely, and filter holes are evenly opened on the water filter cartridge 2, the rotating shaft 3 is concentrically arranged with the water filter cartridge 2, and a spiral blade 5 is fixedly connected to the rotating shaft 3, and the spiral blade 5 is tangent to the inner wall of the water filter cartridge 2, and both ends of the rotating shaft 3 are fixedly connected with a rotating drum frame 6, and the rotating drum frame 6 is rotatably connected to the base 1, and the driving device 4 is provided with two and respectively drives the rotating shaft 3 and the water filter cartridge 2 to rotate in the base 1.

[0019] In this embodiment, if Figure 1As shown, each base 1 is rotatably connected to a ring gear 7, the inner and outer walls of the ring gear 7 are provided with teeth, and both ends of the outer wall of the water filter cartridge 2 are fixedly connected to a circular ring gear 8, the circular ring gear 8 is matched with the inner teeth of the ring gear 7, and a driving device 4 is meshed with the ring gear 7. Through mechanical matching, the filtering efficiency is improved while reducing the cost and energy loss.

[0020] In this embodiment, if Figure 1 As shown, the base 1 is fixedly connected with an annular limiting groove 9, and the drum frame 6 is rotatably installed in the limiting groove 9 through a bearing. The limiting groove 9 limits the rotation position of the spiral blade 5, so that the spiral blade 5 and the filter cartridge cooperate more reasonably and improve the filtration quality.

[0021] In another embodiment, Figure 1 As shown, the end of the rotating shaft 3 located at the lower position is hinged with a shaped barrel 10 and a stopper 11 for limiting the shaped barrel 10, the upper part of the shaped barrel 10 is set to be conical, the lower part of the shaped barrel 10 is open and faces the water filter barrel 2, and the stopper 11 is set obliquely to limit the rotation angle of the shaped barrel 10 toward the lower end of the base 1. The upper part of the shaped barrel 10 close to the end surface of the water filter barrel 2 is set as a filter screen 12. When the water inflow of the water filter cartridge 2 is large, the water flow impacts the filter screen 12 of the special-shaped cartridge 10, and the debris filtered by the filter screen 12 falls on the impact water flow at the lower part of the special-shaped cartridge 10, so as to bring the debris to a position near the middle of the water filter cartridge 2, so as to facilitate the spiral blades 5 to lift the debris. When the water inflow of the water filter cartridge 2 is small, the water flow falls on the bottom surface of the upper part of the special-shaped cartridge 10 opposite to the filter screen 12. Under the action of the continuous water flow, the special-shaped cartridge 10 deviates at a certain angle, so that the lower part of the special-shaped cartridge 10 throws the water flow into a position near the middle of the water filter cartridge 2, so as to facilitate the spiral blades 5 to lift the debris.

[0022] In this embodiment, the rotation direction of the water filter cartridge 2 is opposite to that of the spiral blade 5, and the rotation of the spiral blade 5 lifts the debris entering the water filter cartridge 2 to a higher position of the water filter cartridge 2. When the two rotate in opposite directions, the spiral blade 5 quickly lifts the debris entering the water filter cartridge 2 to a higher position of the water filter cartridge 2.

[0023] In this embodiment, the rotation direction of the water filter cartridge 2 is the same as that of the spiral blade 5, and the rotation of the spiral blade 5 lifts the debris entering the water filter cartridge 2 to a higher position of the water filter cartridge 2, and the rotation speed of the spiral blade 5 is higher than the rotation speed of the water filter cartridge 2. When the two rotate in the same direction, the rotation speed of the spiral blade 5 is higher than the rotation speed of the water filter cartridge 2, so that the debris entering the water filter cartridge 2 is crushed and lifted to a higher position of the water filter cartridge 2.

[0024] In another embodiment, please refer to Figure 1As shown, a discharge port 13 is provided on the base 1 at a high position, and the discharge port 13 is located at the end of the water filter cartridge 2. It is convenient for the debris falling from the water filter cartridge 2 to fall from the discharge port 13, so as to facilitate the collection of the debris.

[0025] In this embodiment, please refer to Figure 1 As shown, the lower end of the water filter cartridge 2 is fixedly connected with a conical bag material barrel 14. The bag material barrel 14 is used to prevent debris from falling outside the water filter cartridge 2.

[0026] The working principle is: the water inlet culvert filter device of the present invention realizes efficient water filtration and automatic cleaning functions through a unique mechanical structure. When working, start the driving device 4 to drive the water filter cartridge 2 and the rotating shaft 3 to rotate. The water flows in from the lower end of the water filter cartridge 2, and flows out after being filtered through the filter hole. At the same time, the spiral blades 5 lift the impurities entering the water filter cartridge 2 to the high end of the water filter cartridge 2 as the rotating shaft 3 rotates, and discharges them through the discharge port 13. The relative rotation direction and speed between the water filter cartridge 2 and the spiral blades 5 can be adjusted as needed to achieve the best filtering effect. The block 11 on the special-shaped cylinder 10 limits its rotation angle to prevent excessive rotation from affecting normal operation. This design not only improves the filtration efficiency, but also simplifies the maintenance process and ensures the stable operation of the device.

[0027] The present invention also provides a water inlet culvert filtering method, using the above filtering device, comprising the following steps: S1, start the driving device 4 to drive the water filter cartridge 2 and the rotating shaft 3 to rotate; S2, water flows in from the lower end of the water filter cartridge 2, and flows out after being filtered through the filter holes; S3, impurities are lifted to the upper end of the water filter cartridge 2 by the spiral blade 5 and discharged through the discharge port 13; S4. According to the amount of impurities in the water flow, the rotation direction and speed of the water filter cartridge 2 and the spiral blade 5 are adjusted to achieve the best filtering effect. When the rotation directions of the two are opposite, the spiral blade 5 will quickly lift the impurities entering the water filter cartridge 2 to a high position of the water filter cartridge 2. When the rotation directions of the two are the same, the rotation speed of the spiral blade 5 is higher than the rotation speed of the water filter cartridge 2, so that the impurities entering the water filter cartridge 2 are crushed and lifted to a high position of the water filter cartridge 2. S5. When the water inflow of the water filter cartridge 2 is large, the water flow impacts the filter screen 12 of the special-shaped cartridge 10, and the debris filtered by the filter screen 12 falls on the impact water flow at the lower part of the special-shaped cartridge 10, so as to bring the debris to the position near the middle of the water filter cartridge 2, so as to facilitate the spiral blade 5 to lift the debris. When the water inflow of the water filter cartridge 2 is small, the water flow falls on the bottom surface of the upper part of the special-shaped cartridge 10 opposite to the filter screen 12. Under the action of the continuous water flow, the special-shaped cartridge 10 deviates at a certain angle, so that the lower part of the special-shaped cartridge 10 throws the water flow into the position near the middle of the water filter cartridge 2, so as to facilitate the spiral blade 5 to lift the debris. S6. Use the bag material barrel 14 to prevent debris from falling into the water filter barrel 2.

[0028] The water inlet box culvert filtering device of the present invention not only solves the problems of low filtering efficiency and inconvenient maintenance in the prior art, but also has the advantages of simple structure and low cost, and has good application prospects.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
