Referring to fig. 1 to 2, the present embodiment provides an ultrapure water micro-filtration device comprising a housing 10, a laminar flow plate 20, a filter plate 30, and an ultraviolet lamp 40.

The shell 10 is provided with a water inlet and a water outlet 11 water inlet; 12. the laminar flow plates 20 are transversely arranged in the shell 10, and a plurality of laminar flow plates are arranged in parallel up and down, and each laminar flow plate 20 can receive water input by the water inlet and guide the water to the water inlet of the water outlet 11; 12. specifically, water flows through the laminar flow plate 20 after entering the shell 10 from the water inlet and flows through the water outlet 11; 12, which may be embodied by connecting a water inlet pipe 60 to the water inlet and delivering water through the water inlet pipe 60 to the plurality of laminar flow plates 20. The filter plates 30 are longitudinally disposed on the laminar flow plate 20, and the filter plates 30 are used to filter water on the laminar flow plate 20. In particular, the water flow is intercepted and filtered by the filter panels 30 as it passes through the laminar flow panels 20. The ultraviolet lamp 40 is disposed in the housing 10, and the ultraviolet lamp 40 emits ultraviolet rays while sterilizing water on the plurality of laminar flow plates 20.

In this embodiment, the laminar flow plate 20 utilizes the horizontal space in the housing 10, and the filter plate 30 utilizes the vertical space, so that the space utilization rate is improved, and the number of the laminar flow plate 20 and the filter plate 30 can be increased in the same space, so that the filtering area is increased, and the efficiency of the whole device is improved. The filter plate 30 may be provided with a plurality of layers according to the need, and the apparatus is illustrated with two layers, namely, an activated carbon plate and an ion exchange resin plate.

In one embodiment, the middle part of the laminar flow plate 20 is provided with a liquid leakage hole 21 penetrating longitudinally, water on the laminar flow plate 20 flows to the liquid leakage hole 21 from the periphery, and finally water is introduced from the water outlet 11 through the liquid leakage hole 21; 12, the ultraviolet lamp 40 passes through the plurality of weeping holes 21 in the longitudinal direction. A gap is formed between the ultraviolet lamp 40 and the inner wall of the weeping hole 21.

In this embodiment, the ultraviolet lamp 40 is disposed in the middle of the laminar flow plate 20, so that the ultraviolet rays emitted by the ultraviolet lamp 40 uniformly sterilize the water flowing around, and in addition, the water is sterilized by the ultraviolet lamp 40 when flowing downwards through the weeping hole 21, thereby increasing the sterilization time period and improving the sterilization effect.

In one embodiment, the filter plates 30 are arranged in a ring shape on the laminar flow plate 20, and the center of rotation of the filter plates 30 is located on the center line of the weep hole 21.

In this embodiment, water is filtered through the annular filter plate 30 in the process of flowing from the periphery of the laminar flow plate 20 to the weeping holes 21, and the filter plate 30 is concentric with the weeping holes 21, so that the distance from the water filtered from the filter plate 30 to the weeping holes 21 is the same, the water flow is uniformly distributed on the laminar flow plate 20, and the ultraviolet lamp 40 has a better irradiation sterilization effect on the water. On the contrary, if the distances from the water filtered by the filter plate 30 to the liquid leakage holes 21 are different, the water distribution is inevitably uneven, the sterilization effect of the ultraviolet lamp 40 is different, and the subsequent improvement of the filtering quality (that is, the uniformity of the water filtering effect is poor) by adjusting the time of filtering the water of the whole device is inconvenient.

In one embodiment, the filter plate 30 is tilted toward the ultraviolet lamp 40. In this embodiment, the filter plate 30 is obliquely disposed, so that the dead angle irradiated by the ultraviolet lamp 40 can be effectively reduced, and the water can be sterilized before being filtered, thereby further improving the sterilization effect.

In one embodiment, gaps exist between the periphery of the laminar flow plate 20 and the inner wall of the shell 10, and the laminar flow plate further comprises an overflow plate 50, a water inlet pipe 60, a partition plate 70, a water outlet pipe 61 and an overflow pipe 62.

The overflow plates 50 are annularly arranged on each laminar flow plate 20, and form an overflow groove 51 with the filter plates 30, wherein the height of the overflow groove 51 is lower than that of the filter plates 30, when the height of water in the overflow groove 51 exceeds that of the overflow plates 50, the water flows out from the overflow plates 50, flows out from gaps between the laminar flow plates 20 and the shell 10, and finally flows to the bottom of the shell 10.

One end of the water inlet pipe 60 communicates with the water inlet and the other end delivers water to the overflow trough 51 of each laminar flow plate 20. Specifically, one end of the water inlet pipe 60 is communicated with the water inlet, and the other end of the water inlet pipe 60 is divided into a plurality of pipe orifices and then positioned above the plurality of overflow tanks 51, so that water is supplied to the plurality of overflow tanks 51. Of course, the inlet pipe 60 may also feed each overflow trough 51 in other ways. The partition plate 70 is annularly arranged at the bottom of the casing 10, and encloses a pure water area 71 with the bottom of the casing 10. One end of the water outlet pipe 61 is connected with the water outlet 11; 12, and the other end is inserted into the pure water region 71 through the partition plate 70. One end of the overflow pipe 62 is located in the housing 10 after passing through the side wall of the housing 10, and the overflow pipe 62 is used for conveying water overflowed from the overflow grooves 51 of each laminar flow plate 20 out of the housing 10. The pure water region 71 is located below the plurality of weep holes 21. In addition, the overflow plate 50 may be arranged obliquely (the present apparatus is shown as being arranged vertically), so that the light of the ultraviolet lamp 40 may irradiate the side of the overflow plate 50 away from the ultraviolet lamp 40, so that the water may be sterilized after entering the whole apparatus from the water inlet pipe 60, and the sterilizing effect is further improved.

In this embodiment, water enters each overflow groove 51 from the water inlet pipe 60, the overflow grooves 51 are annular, and water in the overflow grooves 51 passes through the filter plates 30, is left from the liquid leakage holes 21, enters the pure water area 71, and flows out from the water outlet pipe 61. Since the overflow plate 50 is lower than the filter plate 30 in height, the overflow groove 51 overflows from the overflow plate 50 after filling, flows down from the gap between the laminar flow plate 20 and the inner wall of the housing 10, then collects in the area between the partition plate 70 and the housing 10, and then this part of the water flows out from the overflow pipe 62 and is re-conveyed to the water inlet for the next purification. When water overflows from the overflow plate 50, the overflow plate 50 is annular, the overflowed water is in a small annular waterfall, the thickness of the overflowed water is uniform in the downward flow process, the lamp light of the ultraviolet lamp 40 can be well sterilized, and the water enters fewer bacteria from the water inlet pipe 60. In addition, the overflow plate 50 may be disposed obliquely to reduce the irradiation dead angle of the ultraviolet lamp 40.

In one embodiment, the water inlet pipe further comprises a plurality of annular guide plates 80, the outer rings of the guide plates 80 are connected with the inner wall of the shell 10, the guide plates 80 are arranged below the laminar flow plate 20 in a one-to-one correspondence manner, the inner rings of the guide plates 80 correspond to the overflow grooves 51 below the guide plates, and the end parts of the water inlet pipes 60 are positioned at the opening parts of the overflow grooves 51 of the uppermost laminar flow plate 20. Specifically, a baffle 80 is positioned below each laminar flow plate 20.

In this embodiment, the water inlet pipe 60 only needs to supply water to the overflow tank 51 at the uppermost position, and the water overflowed from the overflow tank 51 at the uppermost position flows into the overflow tank 51 with the next layer after being guided by the guide plate 80.

In one embodiment, a shroud 90 is also included that is annularly disposed on each of the laminar flow plates 20, the shroud 90 surrounding the apertures of the weep holes 21, the shroud 90 being angularly disposed, the shroud 90 being lower in height than the filter plates 30.

In this embodiment, the shroud 90 is directly connected to the orifice of the weep hole 21. The space between the shroud 90 and the filter plate 30 allows the filtered water to temporarily stay in the space, which serves to increase the irradiation time of the ultraviolet lamp 40 and to improve sterilization efficiency.

In the description of the present utility model, numerous specific details are set forth. However, it is understood that embodiments of the utility model may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
