Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, and in particular to a high-efficiency filtering device for a water purifier. Background Art

[0002] With the continuous development of water treatment technology, water purifiers have become an important water purification tool in daily life and industrial production. The core function of water purifiers is to effectively remove suspended matter, bacteria, viruses and other harmful substances in water through physical filtration, chemical adsorption and ultraviolet sterilization of filter elements, providing clean and healthy water sources.

[0003] However, existing water purifiers usually face the following problems:

[0004] Frequent replacement of filter cartridges: Most traditional water purification equipment uses a single type of filter cartridge, which gradually becomes clogged during the water filtering process and needs to be replaced regularly. The replacement of filter cartridges not only increases maintenance costs, but also brings certain inconveniences to users.

[0005] Difficult to clean: Existing water purifier filters usually need to be manually disassembled and cleaned, which is cumbersome and time-consuming, especially for more complex filter structures such as ceramic filter elements and laminated filter elements. If not cleaned in time, the filtering effect of the filter element will be significantly reduced, and even secondary pollution will occur.

[0006] The filter element has a limited lifespan: During long-term use, the filter element is prone to lose its filtering effect, especially when the water quality is poor or the filter load is heavy, resulting in the need for frequent replacement of the filter element, increasing the maintenance cost of the equipment and the inconvenience of use.

[0007] Unsatisfactory cleaning effect: Although some water purification equipment is equipped with a cleaning function, the existing cleaning devices often have limited effects and cannot thoroughly clean the filter element, resulting in low cleaning efficiency of the filter element and inability to effectively extend the service life of the filter element.

[0008] Water purification intensity control problem: The water quality in different regions varies greatly. Existing water purification equipment usually cannot flexibly adjust the filtering effect, especially the combination of filter elements is relatively fixed, and the water treatment intensity cannot be adjusted according to changes in water quality.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The water purifier high efficiency filtering device according to the preferred embodiment of the present invention will be described in detail below.

[0038] Embodiment 1, as Figure 1-Figure 8As shown, a high-efficiency filtering device for a water purifier comprises a shell 1, an annular partition plate 11 is fixedly installed inside the shell 1, a plurality of first small holes 111 are provided on the annular partition plate 11, a cleaning device 2 is rotatably connected to the inner wall of the annular partition plate 11, a movable ceramic filter element 3 is arranged above the cleaning device 2, the inside of the ceramic filter element 3 is a central sleeve 31 with micropores on the surface that allows water to pass from the side, a central inner tube 32 that prevents water from passing from the side is slidably inserted inside the central sleeve 31, and the central inner tube 32 extends to the inside of the cleaning device 2, a top plate 12 and a bottom plate 13 are fixedly installed at the upper and lower ends of the shell 1, a base 4 is fixedly installed on the bottom plate 13, a gap is formed between the base 4 and the bottom of the cleaning device, the central inner tube 32 is fixedly installed with the base 4, and a water outlet channel 41 is provided on the base 4 on the inner side of the central inner tube 32. A cylindrical outer tube 5 is fixedly installed between the base 4 and the annular partition plate 11, and a second small hole 52 is opened on the cylindrical outer tube 5. A plurality of laminated filter chips 51 are arranged on the outside of the cylindrical outer tube 5, and a T-shaped moving part 6 for controlling the movement of the laminated filter element is arranged below the bottom laminated filter chip 51. A first water flow channel 61 is opened on the base 4 between the cleaning device 2 and the outside of the central inner tube 32, a second water flow channel 62 is opened on the bottom plate 13, and the T-shaped moving part is arranged above the end of the second water flow channel 62. A water inlet channel 7 connected to the inside of the shell 1 is fixedly installed on the left side of the bottom plate 13, and an ultraviolet lamp tube 8 is arranged on the base 4 on the inner side of the central inner tube 32. The cross-section of the ceramic filter element 3 is flower-shaped and is twisted 180 degrees from the bottom to the top. The inner wall surface of the cleaning device 2 corresponds to the outer surface of the ceramic filter element 3.

[0039] During operation, the distance that the ceramic filter element 3 enters the interior of the cleaning device 2 is controlled according to the different water qualities, so as to control the contact area between the filter element and water to achieve the effect of controlling the working intensity of the ceramic filter element 3. The pressurized water enters the outside of the laminated filter chip 51 through the water inlet channel 7. When a part of the water enters the inner side of the cylindrical outer tube 5 and then enters the interior of the cleaning device 2, the pressurized water passes through the first channel and the second channel to squeeze the push plate upward, thereby squeezing the laminated filter chip 51 together, so that the laminated filter chip 51 officially enters the working state. After the first filtration through the laminated filter chip 51, the water enters the inner side of the cylindrical outer tube 5. When the water fills the area between the central inner tube and the cylindrical outer tube 5 and the area at the bottom of the cleaning device and the ceramic filter element 3, the water enters the top of the annular partition plate 11 through the first small hole 111. Then, the water enters the interior of the central sleeve 31 through the ceramic filter element 3, and then enters the water outlet channel 41 after being sterilized through the central inner tube 32 and the ultraviolet lamp 8.

[0040] When cleaning is required, water enters the shell 1 through the water inlet channel 7, and controls the ceramic filter element 3 to enter the cleaning device 2 back and forth. When the ceramic filter element 3 moves downward or upward, it will drive the cleaning device 2 to rotate, and the inner wall of the cleaning device 2 will rub and clean the outer surface of the ceramic filter element 3. The ceramic filter element 3 moves upward and away from the cleaning device 2. The water in the first water flow channel 61 will be pumped away upward, thereby driving the T-shaped moving part 6 downward, so that the laminated filter element is dispersed, and the ceramic filter element 3 moves downward into the cleaning device 2. The water in the first water flow channel 61 will be squeezed downward, thereby driving the T-shaped moving part 6 upward, and the laminated filter chip 51 is squeezed. When the ceramic filter element 3 moves downward or upward, the water in the first water flow channel 61 will be squeezed downward. During the upward movement, the laminated filter chips 51 are driven to hit each other, so that the area between the laminated filter chips 51 can be cleaned by vibration. At the same time, when the laminated filter element is dispersed, the cleaning device 2 will drive the water outside it to perform centrifugal movement, thereby being thrown out from the inside of the laminated filter chip 51 to the outside of the laminated filter element, thereby backwashing the laminated filter chip 51 and further cleaning the laminated filter chip 51. At the same time, when the ceramic filter element 3 moves upward and downward, water is drawn upward from the bottom of the central inner tube 32 and discharged outward from the central sleeve 31. The impact force of the water flow can also wash the surface of the ultraviolet lamp, thereby ensuring the working state of the ultraviolet lamp.

[0041] Specifically, water quality parameters can be detected by the existing water quality detection device, and the water quality parameters can be fed back to the processor. The processor can determine the water quality state, and the processor controls the distance that the electric telescopic rod 10 moves downward according to the water quality state. The water quality detection device is used to monitor various indicators of water (such as pH value, dissolved oxygen, turbidity, etc.) in real time. The existing water quality sensor can accurately detect these parameters and feed back the data to the processor. Today's water quality sensor technology is mature enough to transmit data to the control system wirelessly or wired. After receiving the data transmitted by the water quality detection device, the processor can determine the water quality state according to the preset logic. The processor itself can be a single-chip microcomputer or a PLC (programmable logic controller) to make corresponding decisions according to the changes in water quality. The processor can determine whether the current water quality needs to be adjusted according to a predetermined control rule (such as a set threshold) and control the action of the electric telescopic rod. The electric telescopic rod can accurately control the position according to the control signal. The processor drives the electric telescopic rod to move downward or upward by outputting a control signal.

[0042] It is worth noting that the cross-section of the ceramic filter element 3 can increase the contact area between the surface of the ceramic filter element 3 and water through its special flower shape. At the same time, the cross-section of the ceramic filter element 3 is twisted one hundred and eighty degrees from bottom to top. The inner wall surface of the cleaning device 2 corresponds to the outer surface of the ceramic filter element 3. Compared with the traditional cylindrical ceramic filter element 3, the contact area between the flower-shaped ceramic filter element 3 and water can be increased, thereby increasing the water purification efficiency. At the same time, its special shape can drive the cleaning device 2 to rotate during the up and down movement, thereby achieving the effect of backwashing the laminated filter chip 51. Embodiment 2
