[0001] The invention relates to the technical field of filtering equipment, in particular to filtering equipment for water purification. Background Art

[0002] With the acceleration of industrialization and urbanization, the discharge of industrial wastewater, urban and rural domestic sewage, and the use of pesticides and fertilizers have continued to increase, and drinking water sources in many places have been polluted to varying degrees. The content of pollutants in water is seriously exceeded, including inorganic pollution such as chlorine, fluorine, arsenic, organic salts, and microbial pollution such as bacteria and viruses. These pollutants pose a serious threat to human health.

[0003] Facing the serious water pollution problem, water treatment technology is particularly important. Traditional water treatment processes are difficult to achieve multi-stage filtration of water sources.

This movement not only helps to remove finer particles in the water, but also can achieve physical stirring to a certain extent to prevent blockage, thereby improving the cleanliness and transparency of the water quality.

At the same time, the circular array layout of multiple groups of filter tubes, rotating rods and other components ensures the uniformity and efficiency of the filtration effect, which significantly improves the overall filtration efficiency.

[0017] 2. The filtering equipment for water purification introduces adjustment components such as knobs, connecting columns, and rotating columns, so that users can easily adjust the status of the filtering components, such as changing the filtering accuracy or performing maintenance and cleaning.

The design of the front cylinder 409 and the rear cylinder 410 enables the left turn plate 411 and the right turn plate 412 to rotate with the lifting and lowering of the threaded rod 401, further affecting the water flow path and the filtering effect. As the threaded rod 401 rotates and moves, the positioning block 503 drives the front gear 501 to rotate, and transmits the power to the rear gear 504 through the chain 502. The rotation of the rear gear 504 drives the bottom rotating column 508 and the front filter plate 506, the side filter plate 507 and the filter column 509 fixed thereon to rotate.

The filtering device achieves efficient filtration and purification of water sources through its exquisite structural design. When water flows into the device through the filter hole 201 on the outside of the main body 1, it will first be initially filtered through the filter tube 202 to remove larger suspended matter and impurities. The rotating rod 203 fixedly connected inside the filter tube 202 serves as a core component, and a hinged rod 205 is slidably fitted on its outer side. With the continuous action of the water flow, the hinged rod 205 will slide along the rotating rod 203, and through the connection with the hinge block 206 and the hinge head 207 through the hinge hole 204, drive the hinge column 209 and the hinged long rod 208 to perform complex movements. This movement not only increases the contact area between the water flow and the filter medium, but also promotes the disturbance of the water flow, which helps to more thoroughly remove tiny particles and pollutants in the water.

[0027] In one embodiment of the present invention, the filter hole 201, the filter tube 202, the transmission plate 211, the rear gear 504, the gear hole 505, the front filter plate 506, the bottom rotating column 508, the filter column 509, the filter port 510 and the outlet 511 have the same center of the circular cross section, and the filter tube 202, the rotating rod 203, the hinge hole 204, the hinge rod 205, the hinge block 206, the hinge joint 207, the hinge long rod 208, the hinge column 209, the center column 210 and the transmission plate 211 are all provided with multiple groups, and the multiple groups of filter tubes 202, the rotating rod 203, the hinge hole 204, the hinge rod 205, the hinge block 206, the hinge joint 207, the hinge long rod 208, the hinge column 209, the center column 210 and the transmission plate 211 are provided with multiple groups. The long rod 208, the hinge column 209 and the transmission plate 211 are arranged in a circular array outside the central column 210. The limit block 403, the limit hole 404, the limit rod 405, the limit head 406, the limit hole 407 and the limit column 408 are arranged in multiple groups, and the limit block 403, the limit hole 404, the limit rod 405, the limit head 406, the limit hole 407 and the limit column 408 are all arranged on both sides of the threaded block 402 with the vertical center line of the threaded block 402 as the mirror axis. The knob 301, the rotating column 303, the rotating hole 304, the fixed column 305, the threaded rod 401, the front gear 501 and the circular positioning block 503 The center of the cross-section is coaxial, and multiple groups of support rods 7, support plates 8 and anti-sliding blocks 9 are arranged, and the multiple groups of support rods 7, support plates 8 and anti-sliding blocks 9 are arranged in a circular array at the bottom of the main body 1. The adjustment component 4 mainly realizes fine control of the filtering process through the operation of the knob 301. When the knob 301 is rotated, the rotating column 303 and the fixed column 305 are driven to rotate through the connecting column 302, and the threaded rod 401 at the bottom of the fixed column 305 rotates accordingly, driving the threaded block 402 and its accompanying structure to move up and down. In this process, the limit block 403, the limit hole 404, the limit rod 405 and other components play a guiding and limiting role to ensure that the threaded rod 401 moves smoothly, the support rod 7, support plate 8 and anti-slip block 9 at the bottom of the main body 1 together constitute a stable support system, the circular array layout of multiple groups of support rods 7 and support plates 8 ensures the overall stability of the equipment, and can maintain stable operation even under water impact or external force. The design of the anti-slip block 9 effectively prevents the equipment from sliding on wet and slippery ground, thereby improving the safety of use. The filtering device achieves efficient and fine filtration and purification of water sources through its unique filtering component 2, adjusting component 4 and gear transmission system. At the same time, the stable support system and convenient adjustment mechanism also improve the use experience and reliability of the equipment.

[0028] Working principle: When the turbid or impure water first contacts the densely distributed filter holes 201 on the outside of the main body 1, a precise filtering process begins quietly. These filter holes 201 are like gates for preliminary screening, effectively blocking large suspended particles and obvious impurities visible to the naked eye in the water, laying the foundation for subsequent deeper purification. After entering the filter tube 202, the water faces more detailed challenges. Here, the rotating rod 203, as the core of the entire filtering mechanism, not only firmly supports the entire system, but also promotes the dynamic filtering of the water through its unique design. The sliding of the hinged rod 205 on the rotating rod 203 is not a simple linear movement, but changes with the pressure and direction of the water flow, showing a complex dance-like motion trajectory. This movement The movement not only greatly increases the contact area between the water flow and the filter medium, but also drives the hinged column 209 and the hinged long rod 208 to swing and rotate in a complex and orderly manner through the chain reaction of precision components such as the hinge hole 204, the hinge block 206, and the hinge head 207. This dynamic process is like a water symphony in the microscopic world, which effectively promotes the disturbance and mixing of the water flow, allowing the tiny particles and pollutants in the water to contact the filter medium in a wider range, thereby achieving more thorough removal. The adjustment component 4 of the equipment is the key to the user's precise control. By rotating the knob 301, the user can easily adjust the various parameters of the filtration process. Each rotation of the knob 301 is accurately transmitted to the rotating column 303 and the fixed column 303 through the connecting column 302. 5, and then drive the threaded rod 401 to rotate and lift. In this process, the limit block 403, the limit hole 404, the limit rod 405 and other components perform their respective functions to ensure the smooth movement of the threaded rod 401 and avoid the performance degradation caused by vibration or misalignment. What is more clever is that the design of the front cylinder 409 and the rear cylinder 410 provides flexible support for the movement of the left turn plate 411 and the right turn plate 412. As the threaded rod 401 rises and falls, the left turn plate 411 and the right turn plate 412 can not only move vertically, but also produce a certain horizontal displacement through the rotation of the cylinder, thereby changing the path and speed of the water flow inside the device. This design not only improves the filtering effect, but also enhances the adaptability of the device, so that it can maintain under different water quality conditions. To maintain the best working state, with the continuous rotation and movement of the threaded rod 401, the power is efficiently transmitted to the rear gear 504 through the chain 502, and the rotation of the rear gear 504 drives the bottom rotating column 508 and the front filter plate 506, the side filter plate 507 and the filter column 509 fixed thereon to rotate. This rotational movement not only allows the filter medium to contact the water more fully, but also removes the pollutants attached to the surface of the medium through the action of centrifugal force, thereby maintaining the continuity of the filtering effect. The filter medium inside the filter column 509 is the key to achieving deep filtration. These media may include activated carbon, ceramic filter materials or advanced synthetic materials, etc. They have strong adsorption and filtration capabilities, and can further remove tiny particles, dissolved substances and harmful substances in the water.After this series of complex and delicate filtering processes, the originally turbid or impure water finally becomes clear and transparent, and flows out through the filter port 510 and the outlet 511, achieving the purpose of purification. The support system at the bottom of the main body 1 is also an indispensable part of the device. Multiple groups of support rods 7 and support plates 8 are evenly distributed at the bottom of the device in a circular array, providing a stable support foundation for the entire device. This design not only enhances the load-bearing capacity of the device, but also improves its stability when facing water flow impact or external force. Even in harsh operating environments, the device can maintain stable operation, ensuring the stability and reliability of the filtering effect. In addition, the addition of the anti-sliding block 9 adds a solid barrier to the safety of the device. ,

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
