Description

Technical Field

[0001] The utility model relates to the technical field of aquatic product sterilization equipment, in particular to a serpentine over-flow type aquatic product sterilization device. Background Art

[0002] In aquaculture, as artificial breeding ponds are used for a long time, the water environment becomes worse and worse, causing the quality of the cultured products to decline. Therefore, it is necessary to disinfect the water in the breeding ponds. Ultraviolet disinfection is a physical destruction process. It is not affected by chemical equilibrium conditions such as temperature, concentration, and activity. It is non-toxic, mercury-free, residue-free, odor-free, and has high spectral characteristics. It not only has a wide range and is rapid, but also does not introduce impurities during the sterilization process and does not produce new disinfection by-products. It is the first choice for disinfection and sterilization in aquaculture.

[0003] An over-flow sterilization device is a device that processes flowing water during its circulation process to achieve the purpose of disinfection. However, when the existing over-flow sterilization device sterilizes flowing water, due to the fast flow rate, the amount of ultraviolet light that the water can receive is relatively small, resulting in an unsatisfactory sterilization effect. In addition, there is a large optical loss in the propagation process of ultraviolet light, which further reduces the effect of disinfection. In view of the above problems, the utility model proposes a serpentine over-flow aquatic sterilization device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a serpentine over-flow aquatic sterilization device.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A serpentine flow-through aquatic sterilization device, characterized in that the device comprises a water flow tube and a sterilization unit; the water flow tube comprises a plurality of U-shaped tubes arranged in an array, and adjacent U-shaped tubes are connected by C-shaped tubular joints, so that the water flow tube is serpentine; retarder plates are arranged in an alternating array on both sides of the straight tube section of each U-shaped tube, deep ultraviolet LED light strips are respectively arranged on both sides of the bending section of the U-shaped tube, and sterilization units are respectively provided at the pipe openings at both ends; the sterilization unit comprises a filter and a deep ultraviolet LED lamp module, a plurality of filter screens are arranged at intervals at the pipe opening and a deep ultraviolet LED lamp module is arrayed on each filter screen, and the light output direction of the deep ultraviolet LED lamp module is parallel to the straight tube section of the U-shaped tube.

[0007] Furthermore, a deep ultraviolet LED lamp module is arranged at every two intersections along the left-right direction of the filter, and a deep ultraviolet LED lamp module is arranged at each intersection along the up-down direction of the filter.

[0008] Furthermore, the length of the deceleration plate is 0.3 to 0.4 times the length of the straight section of the U-shaped pipe, and the inclination angle of the deceleration plate is 20° to 30°.

[0009] Furthermore, the deceleration plate is made of quartz glass.

[0010] Furthermore, the water flow pipe is made of stainless steel, and the inner wall is coated with a titanium dioxide coating.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. A serpentine water flow pipe is used to lengthen the flow path of water in the device, and the water flow speed is further slowed down by a deceleration plate, thereby lengthening the water flow again, so that the water can be disinfected and sterilized more thoroughly, thereby improving the disinfection and sterilization effect of flowing water.

[0013] 2. Filters are set at both ends of the U-shaped tube, and multiple deep ultraviolet LED light modules are arranged on the filter. A deep ultraviolet LED light module is set at every two intersections along the left and right directions of the filter, and a deep ultraviolet LED light module is set at each intersection along the upper and lower directions of the filter. This design can reduce the light loss of the deep ultraviolet LED light module along the pipeline direction, and the light output direction of the deep ultraviolet LED light module is consistent with the water flow direction, which improves the disinfection and sterilization effect. The deep ultraviolet LED light module is in direct contact with water, and the heat dissipation is more sufficient, which increases the service life of the sterilization unit while reducing the volume of the sterilization unit.

[0018] Specific embodiments are given below in conjunction with the accompanying drawings. The specific embodiments are only used to introduce the technical solution of the utility model in detail, and are not intended to limit the protection scope of the present application.

[0019] The utility model provides a serpentine over-flow aquatic sterilization device (referred to as the device, see Figures 1 to 3), including a water flow tube 1 and a sterilization unit 3; the water flow tube 1 includes a plurality of U-shaped tubes arranged in an array, and adjacent U-shaped tubes are connected by C-shaped tubular joints, so that the water flow tube 1 is serpentine; a plurality of deceleration plates 4 are arranged in a staggered array on both sides of the straight tube section of the U-shaped tube, one end of the deceleration plate 4 is fixedly connected to the U-shaped tube, and the other end extends to the axis of the straight tube section of the U-shaped tube and the deceleration plate 4 faces the bending section of the U-shaped tube, and the deceleration plate 4 is used to slow down the water flow speed; sterilization units 3 are respectively provided at the pipe openings at both ends of the U-shaped tube, and the sterilization unit 3 includes a filter screen 7 and a deep ultraviolet LED lamp module 8, 2 to 5 filter screens 7 are arranged at intervals at the pipe opening of the U-shaped tube and each filter screen 7 completely covers the pipe opening, and the total length of all filter screens 7 is 0.2 to 0.25 times of the straight tube section of the U-shaped tube, leaving enough space for the deep ultraviolet light emitted by the deep ultraviolet LED lamp module 8 to be in contact with the water flow. The process overlaps more, which is beneficial to improving the disinfection and sterilization effect; each filter 7 is arrayed with multiple deep ultraviolet LED lamp modules 8, and the light emitting direction of the deep ultraviolet LED lamp module 8 is parallel to the straight tube section of the U-shaped tube. A deep ultraviolet LED lamp module 8 is arranged at every two intersections in the left and right directions of the filter 7, and a deep ultraviolet LED lamp module 8 is arranged at each intersection in the up and down directions of the filter 7. Such an arrangement is convenient for the deep ultraviolet LED lamp module 8 to emit light, and makes the light emitting direction consistent with the water flow direction to the greatest extent. If the deep ultraviolet LED lamp modules 8 are arranged too densely, it is not conducive to heat dissipation. If the deep ultraviolet LED lamp modules 8 are arranged too sparsely, it will affect the sterilization rate; deep ultraviolet LED light strips 5 are respectively arranged on both sides of the bending section of the U-shaped tube to further sterilize the water after sterilization by the deep ultraviolet LED lamp module 8, thereby improving the sterilization rate.

[0020] The retarder 4 is made of quartz glass, which has good light transmittance, and prevents the retarder 4 from emitting ultraviolet light, thereby reducing the loss of ultraviolet light and improving the sterilization rate. The length of the retarder 4 is 0.3 to 0.4 times the length of the straight section of the U-shaped tube, and the inclination angle of the retarder 4 (the angle between the retarder and the inner wall of the U-shaped tube) is 20° to 30°, which appropriately slows down the water flow speed.

[0021] The inner wall of the water flow pipe 1 is coated with a titanium dioxide coating, which has a strong ultraviolet light shielding function and can greatly reduce the loss of ultraviolet light in the pipe. The water flow pipe 1 is made of stainless steel to avoid rust.

[0022] The inlet and outlet ends of the water flow pipe 1 are respectively provided with threaded connectors 2 for connecting the water flow pipe 1 with an external water inlet and an external water outlet. The inlet and outlet ends of the water flow pipe 1 are respectively provided with water flow velocity meters 6 for detecting water flow velocity.

[0023] The working principle and workflow of the utility model are:

[0024] The device is installed on the outlet pipe of an aquaculture pond. The water to be sterilized in the aquaculture pond enters the water flow pipe 1 from the inlet end of the water flow pipe 1, is disinfected and sterilized by the deep ultraviolet LED lamp module 8 on the filter screen 7 at the pipe mouth of the water flow pipe 1, and then enters the water flow pipe 1. The flow rate is reduced layer by layer by the retarder 4 on the U-shaped pipe. When passing through the bending section of the U-shaped pipe, it is further disinfected and sterilized by the deep ultraviolet LED light strip 5. After passing through multiple U-shaped pipes in sequence, the water is thoroughly disinfected and sterilized and flows out from the outlet end of the water flow pipe.

[0025] Anything not described in the present invention is applicable to the prior art.
