Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Example one
As shown in fig. 1 to 3, the ultraviolet LED lamp bead adapted sterilization device provided in this embodiment includes a cylindrical sterilization chamber 1, an upper cover 2 is screwed continuously to an upper end of the sterilization chamber 1, and an ultraviolet LED lamp bead 3 is fixed on an inner side of the upper cover; the lower end part of the sterilization cavity 1 is provided with a water inlet 4 and a water outlet 5.
In the embodiment, a flat plate partition plate 6 is arranged in the sterilization cavity, the inner space of the sterilization cavity is divided into a first space 7 on the left side and a second space 8 on the right side by the flat plate partition plate 6, the first space and the second space are independent and communicated with each other, the water inlet 4 is communicated with the first space 7, and the water outlet 5 is communicated with the second space 8; the lower end of the flat plate separation plate 6 is tightly attached to the inner wall of the lower side of the sterilization cavity, the second end of the flat plate separation plate 6 is tightly attached to the inner wall of the second side of the sterilization cavity 1, an inverted trapezoidal notch 9 is arranged at the position, opposite to the ultraviolet LED lamp beads, of the second end of the flat plate separation plate 6, and the notch 9 is communicated with the first space 7 and the second space 8.
Through fluid analysis, a certain turbulent flow area still appears near the water inlet and outlet, but in the ultraviolet LED lamp bead irradiation area, the water flow is relatively stable, the flow velocity is high in the central area, the water flow velocity is lower toward the outer ring, the light-emitting angle of the ultraviolet LED lamp bead is 60 degrees, and the relative light intensity is extremely reduced along with the increase of the irradiation angle. Therefore, under the structure, the water flow velocity can well adapt to the light-emitting characteristic of the ultraviolet LED lamp bead, and the ultraviolet energy utilization efficiency is improved. Meanwhile, the sectional area of the communicating part is several times or even tens of times of that of the inlet, so that the flow speed of water flow passing through the communicating area is greatly reduced, the contact time of ultraviolet light and the water flow is prolonged, and the sterilization efficiency is further improved. The first structure can well control the distribution of flow velocity in the cavity and can also ensure that ultraviolet light irradiates a communicated area to sterilize in a concentrated way.
Example two
Different from the first embodiment, the separating element is a circular ring-shaped separating plate 10, which is shown in fig. 4 and 5 and has a shape similar to that of the sterilization chamber, and the circular ring-shaped separating plate 10 separates the inner space of the sterilization chamber 1 into a first space 7 in the middle and a second space 8 in the periphery; the first end of the annular division plate is tightly attached to the inner wall of the first side of the sterilization cavity, the annular division plate is close to the inner wall of the second side of the sterilization cavity or tightly attached to the inner wall of the second side of the sterilization cavity, the second end of the annular division plate is provided with a plurality of notches 9, and the notches are communicated with the first space and the second space. The ultraviolet LED lamp bead is opposite to the first space. Water flows into the cavity from the water inlet in the center of the bottom surface, flows upwards to the ultraviolet irradiation area, then flows to the outer area from the gap at the upper end of the cylindrical wall, and flows out through the water outlet after flowing downwards to the outer area.
The material of the annular division plate is aluminum alloy (or stainless steel) which is subjected to polishing treatment, after ultraviolet light emitted by the ultraviolet LED lamp beads irradiates into water, one part of the ultraviolet light is directly transmitted in the water until being absorbed by the water or the bottom part of the ultraviolet light, and the other part of the ultraviolet light irradiates onto the outer wall of the annular division plate and then enters into the water again through reflection, so that the utilization rate of the ultraviolet light is improved. The structure of this embodiment is stable at the central zone velocity of flow, and is closer to the center simultaneously, and the velocity of flow is higher, compares and implements the advantage and has increased ultraviolet ray optical path more, has improved the ultraviolet utilization ratio.
