Description

Technical Field

[0001] This utility model belongs to the field of aquaculture water treatment technology, and specifically relates to an ultraviolet disinfection water treatment device. Background Technology

[0002] The main disadvantages of existing ultraviolet disinfection in aquaculture are: 1. Ultraviolet rays have weak penetrating power and can only treat the surface and shallow parts of the water, with poor disinfection effect on pathogens and parasites in deep water; 2. Some aquaculture environments are complex, with water flow and fluctuations, resulting in uneven ultraviolet irradiation; 3. The operating cost of the equipment is high, including equipment purchase, installation and maintenance, and power consumption, which increases the cost of aquaculture. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing an ultraviolet disinfection water treatment device that improves the disinfection efficiency of ultraviolet light.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An ultraviolet disinfection water treatment device includes multiple downward-tilting water plates and multiple upward-tilting water plates arranged vertically at intervals in a water treatment channel. The top of the downward-tilting water plates extends above the water surface, and the bottom of the upward-tilting water plates extends to the bottom of the water. The bottom of the downward-tilting water plates and the top of the upward-tilting water plates are staggered at different heights to form a channel for accommodating water flow. An ultraviolet lamp is arranged between the downward-tilting water plates and the upward-tilting water plates.

[0006] To better realize this utility model, the above structure is further optimized by providing a mirror reflection layer on the opposite surfaces of the lower and upper water plates.

[0007] To better realize this utility model, the above structure is further optimized. The ultraviolet lamp is tubular and is vertically arranged between the lower water plate and the upper water plate.

[0008] To better realize this utility model, the above structure is further optimized, and the ultraviolet lamp adopts a quartz lamp tube.

[0009] To better realize this utility model, the above structure is further optimized by including a support net, and the lower water plate and the upper water plate are respectively fixedly installed in the water treatment channel by multiple support nets.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] The ultraviolet disinfection water treatment device provided by this utility model utilizes up and down tilting water plates of different heights to form an undulating water flow channel, which lengthens the water flow path. This means that within the same space, the water flow stays in the water treatment device for a significantly longer period, and the disinfection time in contact with ultraviolet light is naturally extended, thus ensuring sufficient disinfection and sterilization effects.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please refer to Figure 1 The ultraviolet disinfection water treatment device provided in this application includes multiple downward-tilting water plates 2 and multiple upward-tilting water plates 3 arranged vertically at intervals in a water treatment channel 1. The tops of the downward-tilting water plates 2 extend above the water surface, and the bottoms of the upward-tilting water plates 3 extend to the bottom of the water. The bottoms of the downward-tilting water plates 2 and the tops of the upward-tilting water plates 3 are staggered at different heights, forming a channel to accommodate water flow. The staggered arrangement of the downward-tilting water plates 2 and upward-tilting water plates 3 creates an undulating water flow channel. The water flow must continuously alternate between the downward-tilting water plates 2, upward-tilting water plates 3, and downward-tilting water plates 2, etc. This arrangement lengthens the water flow path, which means that the residence time of the water flow in the water treatment device is significantly increased within the same space. Moreover, ultraviolet lamps 4 are installed between the downward-tilting water plates 2 and upward-tilting water plates 3, which naturally extends the disinfection time of the water flow in contact with ultraviolet light, ensuring sufficient disinfection and sterilization effects.

[0020] Furthermore, in order to improve the efficiency of disinfection and sterilization, a mirror reflective layer is provided on the opposite surfaces of the lower water plate 2 and the upper water plate 3. When the ultraviolet lamp 4 is irradiated, the ultraviolet light can penetrate the water from more angles and a wider range with the help of the mirror reflection, so that the ultraviolet light can have more sufficient contact with the water, the disinfection intensity is significantly improved, and the water quality is protected in all aspects.

[0021] The ultraviolet lamp 4 is tubular and vertically positioned between the lower water plate 2 and the upper water plate 3, which increases the contact time between the water flow and ultraviolet light, thereby improving the disinfection efficiency. The ultraviolet lamp 4 uses a quartz lamp tube, and quartz glass has excellent transmittance in the ultraviolet spectrum.

[0022] It also includes support nets 5, with the lower tilting water plate 2 and the upper tilting water plate 3 fixedly installed in the water treatment channel 1 via multiple support nets 5. The support nets 5 support the upper and lower tilting water plates, making installation and disassembly of the tilting water plates very convenient, facilitating future maintenance and height adjustment. Secondly, the support nets 5 also serve a filtering function, filtering impurities from the water, improving water quality and increasing water permeability, facilitating subsequent disinfection and sterilization processes.

[0023] This application has a simple structure and powerful functions. Its performance can be expanded according to the usage scenario, which simplifies the installation workload for aquaculture farmers. Daily maintenance and installation / disassembly are also very convenient, which is conducive to the development of factory-style recirculating aquaculture.

[0024] During operation, the water first flows downward from the left side, passing over the lower water plate 2, then flows upward over the upper water plate 3, and then downward over the second water plate 2, thus forming a undulating flow path. This prolongs the time the water stays in the water treatment device. During the water treatment process, the water is in constant contact with the ultraviolet rays emitted by the ultraviolet lamp 4, ensuring that the water is adequately disinfected and sterilized. Finally, the water flows out from the right side of the water treatment device.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
