Description

Technical Field

[0001] This utility model belongs to the field of ultraviolet sterilization technology, specifically an ultraviolet sterilization and algae removal device. Background Technology

[0002] Ultraviolet (UV) sterilization and algae removal devices utilize UV-C band (200~280nm) ultraviolet light to destroy the DNA / RNA structure of microorganisms (bacteria, viruses, algae), causing them to lose their reproductive ability and die. The core components are the UV lamp and quartz sleeve. Water flowing through the reaction chamber receives a sufficient dose of radiation (intensity × time) to achieve physical disinfection. This technology leaves no chemical residue, but it has high requirements for water quality (turbidity, light transmittance) and requires regular maintenance of the lamp and cleaning of the sleeve. It is suitable for scenarios such as drinking water, wastewater, and industrial circulating water.

[0003] Existing ultraviolet sterilization and algae removal devices work by having water flow through pipes inside the device, with ultraviolet lamps arranged around the perimeter of the pipes. The ultraviolet light emitted by these lamps kills bacteria and algae. This method, which allows water to flow directly through the device, has the following drawbacks:

[0004] 1. In static or laminar flow conditions, the distribution of microorganisms in the liquid is uneven. Some areas may receive insufficient dose (below the lethal dose) due to their distance from the ultraviolet lamp, resulting in incomplete sterilization.

[0005] 2. Microorganisms, algae, or particulate matter may block ultraviolet radiation from each other, especially in highly turbid water bodies, increasing the survival rate of microorganisms that are not directly exposed to ultraviolet radiation. Utility Model Content

[0006] To achieve the above objectives, this invention solves the problem that traditional ultraviolet sterilization and algae removal devices suffer from insufficient sterilization due to excessively stable water flow. The invention provides the following technical solution:

[0007] The purpose of this utility model is to provide an ultraviolet sterilization and algae removal device, comprising:

[0008] The outer shell has an internal cavity, and the two ends of the outer shell are respectively provided with a water inlet and a water outlet;

[0009] An ultraviolet lamp is placed on the wall of the receiving cavity;

[0010] The sterilization tube is located inside the receiving cavity and runs through the inlet and outlet of the water.

[0011] The stirring tube is connected at one end to the wall of the receiving cavity and at the other end to the sterilization tube;

[0012] A stirrer is located on the outer casing, and the output end of the stirrer enters the sterilization tube through a stirring tube.

[0013] Preferably, the sterilization tube is an L-shaped tube, with one end of the stirring tube connected to the bend of the sterilization tube and the other end connected to the upper wall of the receiving cavity.

[0014] Preferably, the stirrer includes a stirring motor and a stirring rod. The stirring motor is connected to the housing, and the stirring rod is connected to the output end of the stirring motor. The stirring rod extends from one end of the stirring tube into the sterilization tube.

[0015] Preferably, the stirring rod extends in a spiral shape.

[0016] Preferably, the output end of the stirring motor is connected to a magnetic component. The magnetic component includes a connecting part connected to the output of the stirring motor and a plurality of magnetic rods surrounding the connecting part, with the plurality of magnetic rods extending to the side of the outer casing. A first magnetic plate is provided at the end of each of the plurality of magnetic rods facing away from the connecting part, and all of the first magnetic plates face the outer casing. A rotating disk is provided at the top of the stirrer, and the rotating disk is rotatably connected to the wall of the receiving cavity.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0030] like Figure 1-4 To address the problems mentioned in the background art, this utility model proposes an ultraviolet sterilization and algae removal device, comprising a shell 1, an ultraviolet lamp 2, a sterilization tube 3, a stirring tube 4, and a stirrer 5. The shell 1 has an internal cavity 11, with an inlet 12 and an outlet 13 at each end; the inlet 12 and outlet 13 are respectively connected to water pipes for transporting liquid; the ultraviolet lamp 2 is disposed on the cavity wall of the cavity 11 for sterilization and algae removal; the sterilization tube 3 is disposed within the cavity 11 and extends through the inlet 12 and outlet 13; one end of the stirring tube 4 is connected to the cavity wall of the cavity 11, and the other end is connected to the sterilization tube 3; the stirrer 5 is disposed on the shell 1, and the output end of the stirrer 5 enters the sterilization tube 3 through the stirring tube 4.

[0031] In this application, the stirring tube 4 is connected to the sterilization tube 3. The stirrer 5 extends into the sterilization tube 3 through the stirring tube 4 to stir the liquid passing through the sterilization tube 3, forming a vortex. This allows the microorganisms and algae in the liquid to be fully mixed, avoiding insufficient irradiation in some areas due to stagnant water flow or stratification. This ensures that all microorganisms receive a sufficient dose of ultraviolet light, thereby improving the quality of sterilization and algae removal. It also allows microorganisms, algae, or particulate matter to move around, reducing the aggregation of microorganisms or their attachment to particulate matter, and improving the inactivation rate.

[0032] In this embodiment, the sterilization tube 3 is an L-shaped tube, and one end of the stirring tube 4 is connected to the bend of the sterilization tube 3, while the other end is connected to the upper wall of the receiving cavity 11. Preferably, the inlet 12 is located on the side wall of the outer shell 1, the outlet 13 is located at the bottom of the outer shell 1, and the stirring tube 4 extends from the bend of the sterilization tube 3 to the top wall of the receiving cavity 11. With this configuration, the liquid entering through the inlet 12 flows towards the outlet 13 under the influence of gravity, preventing liquid from entering the stirring tube 4. This reduces the airtightness requirement between the stirring tube 4 and the outer shell 1, thereby reducing the installation accuracy of the stirrer 5.

[0033] In this embodiment, the bottom of the outer shell 1 is a bottom cover, and the bottom cover is connected to the shell body by threads or bolts. When performing maintenance and replacement, only the bottom cover needs to be removed to replace the ultraviolet lamp 2 or maintain other structures.

[0034] Example 1, as Figure 2The stirrer 5 includes a stirring motor 51 and a stirring rod 52. The stirring motor 51 is connected to the outer casing 1, and the stirring rod 52 is connected to the output end of the stirring motor 51. The stirring rod 52 extends from one end of the stirring tube 4 into the sterilization tube 3. The stirring motor 51 can be installed outside the outer casing 1, with a through hole in the outer casing 1 to allow the stirring motor to penetrate into the stirring tube 4. This connection reduces the installation difficulty of the stirring motor 51 and facilitates motor maintenance and replacement. During operation, the stirring motor 51 drives the stirring rod 52 to rotate, thereby rotating the liquid in the sterilization tube 3. The stirring rod 52 extends in a spiral shape. The spiral stirring rod 52 generates three-dimensional turbulence, prolonging the ultraviolet exposure time of microorganisms, improving irradiation uniformity, and reducing dead zones. Its low-resistance design is energy-efficient and prevents particle deposition and biofilm formation, making it particularly suitable for high-turbidity or algae-containing water bodies, significantly enhancing the sterilization and algae removal effect while reducing energy consumption.

[0035] Example 2, as Figure 1 and Figure 3 If the pressure in the sterilization tube 3 is too high, liquid may flow back into the stirring tube 4. Therefore, the airtightness between the stirring tube 4 and the outer shell 1 needs to be improved. The stirring motor 51 is installed on the outside of the outer shell 1. A magnetic component 6 is connected to the output end of the stirring motor 51. The magnetic component 6 includes a connecting part 61 connected to the output of the stirring motor 51 and multiple magnetic rods 62 surrounding the connecting part 61. The multiple magnetic rods 62 extend to the side of the outer shell 1. The end of the multiple magnetic rods 62 facing away from the connecting part 61 is provided with a first magnetic piece 63, and the multiple first magnetic pieces 63 all face the outer shell 1. The top of the stirrer 5 is provided with a rotating disk 64, which is rotatably connected to the cavity wall of the receiving cavity 11. Multiple second magnetic pieces 65 are arranged around the side of the rotating disk 64. The spacing between the multiple second magnetic pieces 65 is consistent with the spacing between the multiple first magnetic pieces 63. Each first magnetic piece 63 is magnetically connected to a corresponding second magnetic piece 65. During operation, the stirring motor 51 rotates, driving the magnetic component 6 to rotate. The magnetic rod 62 in the magnetic component 6 rotates, driving the first magnetic plate 63 to rotate, which in turn drives the second magnetic plate 65 in the stirring rod 52 to rotate. Subsequently, the stirring rod 52 rotates, causing the liquid in the sterilization tube 3 to rotate. This design allows for contactless transmission between the stirring motor 51 and the stirring rod 52, reducing the production requirements of the stirring motor 51 and the difficulty of maintenance and replacement.

[0036] However, this embodiment uses contactless transmission, and the rotation of the first and second sensing plates cannot be guaranteed to be synchronized. Therefore, an embodiment three is provided, such as... Figure 4 In this embodiment, the stirring motor 51 is directly placed inside the sterilization tube 3 and connected to the cavity wall of the receiving cavity 11; the output end of the stirring motor 51 is connected to the stirring rod 52 by a coupling 53. This arrangement can ensure the airtightness of the stirring tube 4 and also make the rotation of the stirring rod 52 and the stirring motor 51 synchronized.

[0037] In the above embodiments, ultraviolet lamps 2 are distributed around the cavity wall of the receiving cavity 11, extending from the inlet 12 to the outlet 13. The surrounding distribution of ultraviolet lamps 2 allows the light to uniformly cover the water flow 360°, eliminating irradiation dead spots and improving sterilization efficiency; at the same time, it shortens the ultraviolet penetration distance, ensuring that even highly turbid water can be fully sterilized, and reducing energy waste caused by uneven illumination on one side, making the device structure more compact and easier to maintain.

[0038] In the above embodiments, a filter screen 14 is detachably installed at the water inlet 12. The filter screen 14 can pre-intercept large impurities such as suspended particles and algae clumps, reduce water turbidity, and prevent them from blocking ultraviolet rays or depositing in the reaction chamber, thereby improving ultraviolet light penetration, reducing equipment clogging, and extending the maintenance cycle of UV lamps and quartz sleeves, ensuring stable and efficient sterilization and algae removal effects.
