Description

Technical Field

[0001] The invention relates to the technical field of filtration and disinfection, and in particular to a multifunctional multi-stage filtration and disinfection device. Background Art

[0002] Nutrient solution is a new type of liquid synthesized by biological fermentation, chemical chelation, physical activation and other processes using environmental biological ecological symbiosis technology and mycorrhizal symbiosis principles. Nutrient solution is the key to soilless cultivation, and different crops require different nutrient solution formulas. There are many formulas published in the world, but they are similar because the original formulas are derived from the chemical composition analysis of soil extracts. The biggest difference in the nutrient solution formula is the ratio of nitrogen and potassium. In the process of nutrient solution treatment, it is necessary to filter impurities such as plant roots and filter and disinfect the chemical reagent solution, which requires a filtering and disinfection device to complete this task.

[0003] After searching, the Chinese patent application number CN201720293675.9 discloses a simple and efficient domestic sewage filtration and disinfection treatment device, including a water inlet pipe, a filter chamber, a coarse grid and a fine grid in the filter chamber, the filter chamber is connected to the flocculation chamber through an overflow port A, the flocculation chamber is provided with a stirring device, the flocculation chamber is provided with a partition and a filter net, the bottom of the flocculation chamber is provided with a sewage outlet, the flocculation chamber is connected to the disinfection chamber through an overflow port B, the disinfection chamber is also provided with a stirring device, the disinfection chamber is also provided with an exhaust port, and an ozone generator is provided below the disinfection chamber. The simple and efficient domestic sewage filtration and disinfection treatment device in the above patent has the following shortcomings: liquid filtration adopts a multi-filter filtration method. Although this method can achieve filtering, it is very troublesome to clean the filter net and it is inconvenient to carry, which brings inconvenience to production.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multifunctional multi-stage filtering and disinfecting device comprises a Tesla valve structure cavity, wherein two groups of Tesla valve structure cavity bodies connected in forward and reverse directions are arranged in the Tesla valve structure cavity, and a plurality of acceleration zone cavities and deceleration zone cavities are respectively arranged in the two groups of Tesla valve structure cavity bodies, the number of the acceleration zone cavities is greater than the number of the deceleration zone cavities, a chemical disinfection cavity is arranged in each of the acceleration zone cavities, and a physical disinfection cavity is arranged in each of the deceleration zone cavities, and an inlet and an outlet are respectively opened on the outer walls at both ends of the Tesla valve structure cavity.

[0007] Preferably, the inner wall of each of the acceleration zone cavities where the cavities converge is respectively clamped with a first filter screen, a second filter screen, a third filter screen, a fourth filter screen, a fifth filter screen, a sixth filter screen and a seventh filter screen.

[0008] Furthermore: a Tesla valve structure cavity sealing cover is fixed to the outer wall of one side of the Tesla valve structure cavity through a sealing strip, and a Tesla valve structure cavity sealing cover is fixed to the outer wall near each acceleration zone cavity and deceleration zone cavity through a sealing strip.

[0009] On the basis of the above-mentioned solution: a power supply interface is provided on the outer wall of one side of the sealing cover of each of the deceleration zone cavities, and a sealing ring is clamped on the inner wall of each power supply interface.

[0010] A better solution in the above solution is that a UV lamp is clamped in each of the deceleration zone cavities via a buckle.

[0017] 3. The first filter, the second filter, the third filter, the fourth filter, the fifth filter, the sixth filter and the seventh filter are arranged from large to small apertures at the entrance for multi-stage filtration, which can not only reduce the clogging caused by the small apertures of the filter, but also filter multiple times to fully filter out impurities of various diameters; preferably, according to the needs of physical filtration, not all filters may be placed.

[0018] 4. By providing a power supply interface, a sealing cover, a sealing ring and a UV lamp, it is convenient to place UV lamps of different quantities and powers according to needs, and it is also convenient to replace them. At the same time, by providing a card slot and a card strip, it is convenient to replace filters of various apertures, and it is also convenient to disassemble and clean.

[0019] 5. The overall structure is set as a Tesla valve structure, which does not require internal mechanical movement. The liquid is pushed by a physical mechanism, which reduces the energy loss of the liquid during transportation, thereby greatly improving the filtration and disinfection quality of the overall device.

The liquid after passing through the acceleration zone cavity then enters the deceleration zone cavity, and is physically disinfected by the physical disinfection chamber 10 in the deceleration zone cavity. The disinfected liquid finally flows out of the Tesla valve structure cavity 1 through the outlet 102.

[0031] Among them, the inner wall of the converging point of each acceleration zone cavity is respectively clamped with the first filter screen 2, the second filter screen 3, the third filter screen 4, the fourth filter screen 5, the fifth filter screen 6, the sixth filter screen 7 and the seventh filter screen 8. The first filter screen 2, the second filter screen 3, the third filter screen 4, the fourth filter screen 5, the fifth filter screen 6, the sixth filter screen 7 and the seventh filter screen 8 perform multi-stage filtration from large to small aperture at the entrance, which can not only reduce the blockage caused by the small aperture of the filter screen, but also can filter multiple times to fully filter out impurities of various diameters; preferably, according to the needs of physical filtration, not all filters may be placed.

[0032] Among them, a Tesla valve structure cavity sealing cover 104 is fixed to the outer wall of one side of the Tesla valve structure cavity 1 through a sealing strip, and a sealing cover 11 is fixed to the outer wall of the Tesla valve structure cavity sealing cover 104 near each acceleration zone cavity and deceleration zone cavity through a sealing strip, and a power supply interface 106 is opened on the outer wall of one side of the sealing cover 11 of each deceleration zone cavity, and a packing cover is hinged on the outer wall of one side of the sealing cover 11 of each acceleration zone cavity, and a sealing ring is clamped on the inner wall of each power supply interface 106, and a UV lamp 12 is clamped in each deceleration zone cavity through a buckle; it is convenient to place UV lamps 12 of different quantities and powers according to needs, and it is also convenient to replace.

The V lamp 12 performs slow physical disinfection, and the disinfected liquid finally flows out of the Tesla valve structure cavity 1 through the outlet 102. During the whole process, the liquid expands and then compresses when passing through the acceleration zone cavity. The change in pressure difference generates thrust, which effectively and quickly pushes the liquid for filtration. No internal mechanical movement is required. The liquid is pushed by a physical mechanism, which reduces the energy loss of the liquid during transportation. When passing through the deceleration zone cavity, the liquid flow rate will be slowed down, so that it can perform effective and thorough physical disinfection, greatly improving the filtration and disinfection quality of the overall device.
