Description

Technical Field

[0001] This utility model relates to the technical field of marine aquaculture equipment, specifically a seawater disinfection device for marine aquaculture. Background Technology

[0002] With the large-scale and intensive development of marine aquaculture, the hygiene and safety of the aquaculture water directly determine the survival rate, growth quality and final economic benefits of the cultured organisms. Therefore, seawater disinfection has become an indispensable core link in the aquaculture process.

[0003] During marine aquaculture, harmful bacteria, viruses, parasites and other pathogenic microorganisms can easily proliferate in the water. If disinfection is not thorough, it can easily lead to large-scale disease outbreaks, causing mass mortality of farmed organisms and resulting in serious economic losses.

[0004] The prior art patent document CN204968983U provides a seawater disinfection device for marine aquaculture. This device reduces ozone waste by reusing recycled gas, thereby reducing the cost of use to a certain extent and providing convenience for aquaculture farmers.

[0005] The aforementioned existing technologies also use a stirring mechanism to agitate seawater to promote the mixing of seawater and disinfection medium. However, in practical applications, the existing stirring mechanisms have poor mixing effects, only achieving unidirectional agitation of seawater and failing to make the seawater and disinfection medium mix more evenly. Furthermore, existing technologies mostly employ single disinfection methods, such as ozone disinfection, chemical disinfection, and ultraviolet disinfection, and cannot combine multiple disinfection methods. Therefore, we need a seawater disinfection device for marine aquaculture. Utility Model Content

[0006] The purpose of this invention is to provide a seawater disinfection device for marine aquaculture, so as to solve the problems mentioned in the background art, such as poor mixing effect of existing stirring mechanisms and single disinfection method.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seawater disinfection device for seawater aquaculture, including a tank, a waterproof outer shell fixedly connected to the inner wall of the tank, and a stainless steel reflective inner liner provided on the inner wall of the tank. A tank cover is fixedly connected to the top of the tank by bolts, and a stirring assembly is provided on the top of the tank cover. A dosing assembly is also provided on the top of the tank cover. The stirring assembly includes a servo motor, and the output shaft of the servo motor is fixedly connected to a rotating shaft via a coupling. A hollow tube is fixedly connected to the bottom of the tank lid, and a large gear is fixedly connected to the outer wall of the hollow tube. One end of the rotating shaft passes through the hollow tube and is fixedly connected to an arc-shaped plate, and a bearing is fixedly connected to the inner wall of the arc-shaped plate. A rotating rod is fixedly connected to the inner wall of the bearing, and a small gear is fixedly connected to one end of the rotating rod. The other end of the rotating rod is fixedly connected to a stirring rod via a coupling. The stirring rod can stir the seawater inside the stainless steel reflective inner tank. The dosing assembly includes a storage tank with an observation window on the outside. A threaded cap is threaded to the inlet at the top of the storage tank, and a dispensing pipe is fixedly connected to the bottom of the storage tank. One end of the dispensing pipe is connected to the inlet of a metering pump, and a dispensing pipe is fixedly connected to the outlet of the metering pump. One end of the dispensing pipe passes through the tank cover and extends into the tank body.

[0008] Preferably, the inner wall of the stainless steel reflective liner is equipped with a liquid level sensor, a pH sensor, and a temperature sensor. The detection ends of each sensor are in direct contact with seawater, which can monitor the seawater status parameters in real time. The stainless steel reflective liner is made of high reflectivity stainless steel, which can effectively reflect sterilization light.

[0009] Preferably, there are multiple waterproof shells, and the multiple waterproof shells are arranged at equal intervals along the circumference of the tank. An ultraviolet germicidal lamp is installed inside the waterproof shell, and a transparent lens is fixedly connected to the inner wall of the waterproof shell. The transparent lens is made of high light transmittance quartz glass.

[0010] Preferably, the can lid forms a rotating structure with a servo motor and a rotating shaft, and the fixed end of the servo motor is connected to the top of the can lid through a motor bracket, and the output end is connected to the rotating shaft coaxially after passing through the reserved mounting hole of the can lid.

[0011] Preferably, the outer side of the large gear meshes with the outer side of the small gear, and both the large gear and the small gear are arranged horizontally. The stirring rod is a combination structure of an L-shaped rod and a crossbar.

[0012] Preferably, a metering mark is provided on the outside of the observation window, and the medicine storage container is fixed to the lid by a support foot.

[0013] Preferably, a water inlet pipe is fixedly connected to the outside of the tank, and a flow control valve is installed on the water inlet pipe. A drain valve is fixedly connected to the bottom of the tank, and a filter screen is installed at the outlet end of the drain valve.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: First, this utility model solves the problem of poor mixing effect caused by unidirectional stirring in the prior art through the innovative design of the stirring component. When the servo motor drives the rotating shaft to rotate the arc plate, the rotating rod connected to the bearing on the inner wall of the arc plate revolves with the whole. At the same time, because the small gear at one end of the rotating rod meshes with the large gear fixed on the outer wall of the hollow tube, the small gear will drive the rotating rod and the L-shaped stirring rod at the end to rotate during the revolution. This can form multi-directional and dead-angle stirring of the seawater in the stainless steel reflective inner tank, improve the contact area and mixing efficiency of seawater and disinfection media such as medicine, and avoid the situation of incomplete local disinfection.

[0015] Secondly, this utility model solves the problem of the single disinfection method in the existing technology by combining chemical disinfection and ultraviolet disinfection. The storage tank can store disinfectant, and the metering mark on the outside of the observation window makes it easy to monitor the remaining amount of disinfectant in real time. The metering pump can control the amount of disinfectant added. Multiple ultraviolet germicidal lamps emit ultraviolet light, and the high light transmittance quartz glass transparent lens on the waterproof shell can reduce ultraviolet light loss. Combined with the high reflectivity stainless steel reflective liner, ultraviolet light can form a dense sterilization light network inside the tank. The two disinfection methods complement each other, which can cover more types of harmful organisms and improve the comprehensiveness of disinfection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, a seawater disinfection device for marine aquaculture includes a tank 1, a waterproof outer shell 2 fixedly connected to the inner wall of the tank 1, and a stainless steel reflective inner liner 3 provided on the inner wall of the tank 1. A tank cover 4 is fixedly connected to the top of the tank 1 by bolts, and a stirring component 5 is provided on the top of the tank cover 4. A dosing component 6 is provided on the top of the tank cover 4. The stirring assembly 5 includes a servo motor 501, and the output shaft of the servo motor 501 is fixedly connected to a rotating shaft 502 via a coupling. A hollow tube 508 is fixedly connected to the bottom of the tank cover 4, and a large gear 509 is fixedly connected to the outer wall of the hollow tube 508. One end of the rotating shaft 502 passes through the hollow tube 508 and is fixedly connected to an arc plate 503. A bearing 504 is fixedly connected to the inner wall of the arc plate 503. A rotating rod 505 is fixedly connected to the inner wall of the bearing 504. A small gear 506 is fixedly connected to one end of the rotating rod 505, and a stirring rod 507 is fixedly connected to the other end of the rotating rod 505 via a coupling. The stirring rod 507 can stir the seawater in the stainless steel reflective inner tank 3. The dosing assembly 6 includes a storage tank 601, and an observation window 602 is provided on the outside of the storage tank 601. A threaded cap 603 is threadedly connected to the inlet at the top of the storage tank 601, and a dispensing pipe 604 is fixedly connected to the bottom of the storage tank 601. One end of the dispensing pipe 604 is connected to the inlet of the metering pump 605, and a dispensing pipe 606 is fixedly connected to the outlet of the metering pump 605. One end of the dispensing pipe 606 passes through the tank cover 4 and extends into the tank body 1.

[0020] Through the above technical solution, the waterproof shell 2 provides protection for the ultraviolet germicidal lamp and avoids seawater corrosion. The waterproof shell 2 and the transparent lens 10 are sealed together to prevent seawater from entering through gaps. By setting the stainless steel reflective inner liner 3, not only can the utilization rate of the germicidal light be improved, but the corrosion resistance of the tank body 1 can also be enhanced, and the service life of the device can be extended. The tank cover 4 is fixed to the tank body 1 with bolts, which is convenient for installation and disassembly and convenient for later maintenance.

[0021] Specifically, the inner wall of the stainless steel reflective inner liner 3 is equipped with a liquid level sensor 7, a pH sensor 8, and a temperature sensor 9. The detection ends of each sensor are in direct contact with seawater, which can monitor the seawater status parameters in real time. The stainless steel reflective inner liner 3 is made of high reflectivity stainless steel, which can effectively reflect sterilization light.

[0022] Through the above technical solution, the detection ends of the liquid level sensor 7, pH sensor 8, and temperature sensor 9 directly contact seawater, enabling the collection of key parameters such as seawater volume, pH, and temperature. The liquid level sensor 7 provides data for the metering pump 605 to add chemicals, avoiding mismatch between the dosage and the seawater volume. The pH sensor 8 can promptly report changes in the pH of the water after the addition of chemicals. The temperature sensor 9 can help determine the stability of the working environment of the ultraviolet germicidal lamp, preventing abnormal temperatures from affecting the sterilization intensity. At the same time, the high-reflectivity stainless steel inner tank can reflect ultraviolet rays multiple times, expanding the coverage area of ​​ultraviolet rays within the stainless steel reflective inner tank 3, reducing sterilization blind spots, and improving the efficiency of ultraviolet disinfection.

[0023] Specifically, there are multiple waterproof shells 2, and the multiple waterproof shells 2 are evenly spaced along the circumference of the tank body 1. An ultraviolet germicidal lamp is installed inside the waterproof shell 2, and a transparent lens 10 is fixedly connected to the inner wall of the waterproof shell 2. The transparent lens 10 is made of high light transmittance quartz glass.

[0024] Through the above technical solution, multiple waterproof shells 2 are distributed equidistantly along the circumference to ensure that the ultraviolet germicidal lamps can release ultraviolet rays from different directions of the stainless steel reflective inner liner 3, covering all areas of seawater flow and avoiding incomplete disinfection of local seawater due to insufficient light; the transparent lens 10 made of high light transmittance quartz glass can minimize the loss of ultraviolet rays during the propagation process, allowing ultraviolet energy to act on seawater more efficiently and improving sterilization efficiency.

[0025] Specifically, the can lid 4 forms a rotating structure through the servo motor 501 and the rotating shaft 502. The fixed end of the servo motor 501 is connected to the top of the can lid 4 through the motor bracket, and the output end is coaxially connected to the rotating shaft 502 after passing through the reserved mounting hole of the can lid 4.

[0026] Through the above technical solution, the servo motor 501 is fixed to the top of the can cover 4 by the motor bracket to ensure the stability of the motor during operation. Its output end is coaxially connected to the rotating shaft 502, which can transmit the power of the motor to the rotating shaft 502, thereby driving the arc plate 503 to rotate stably.

[0027] Specifically, the outer side of the large gear 509 meshes with the outer side of the small gear 506, and both the large gear 509 and the small gear 506 are horizontally arranged. The stirring rod 507 is a combination structure of an L-shaped rod and a crossbar.

[0028] Through the above technical solution, the large gear 509 is fixed to the outer wall of the hollow tube 508 and remains stationary. When the small gear 506 rotates with the arc plate 503, it rotates due to meshing with the large gear 509, which in turn drives the rotating rod 505 and the stirring rod 507 to rotate synchronously. This allows the stirring rod 507 to rotate while rotating, expanding the stirring coverage area and forming multi-directional, dead-angle-free agitation of the seawater. This increases the contact area and mixing efficiency between the seawater and disinfectant media such as disinfectant solutions, avoiding blind spots in local disinfection.

[0029] Specifically, a metering mark is provided on the outside of the observation window 602, and the medicine storage tank 601 is fixed to the tank cover 4 by a support foot.

[0030] Through the above technical solution, the metering mark on the outside of the observation window 602 allows farmers to intuitively grasp the remaining amount of medicine in the tank without disassembling the medicine storage tank 601, which facilitates timely replenishment of medicine and reduces operation steps; the support feet fix the medicine storage tank 601 to the tank cover 4 to ensure that the medicine storage tank 601 remains stable during the operation of the device.

[0031] Specifically, a water inlet pipe 11 is fixedly connected to the outside of the tank body 1, and a flow control valve is installed on the water inlet pipe 11. A drain valve 12 is fixedly connected to the bottom of the tank body 1, and a filter screen is installed at the outlet end of the drain valve 12.

[0032] Through the above technical solution, the water inlet pipe 11 is connected to an external flow control valve, and the flow control valve is connected to a pipeline for transporting seawater. By setting a flow control valve on the water inlet pipe 11, it is convenient to control the injection speed of seawater into the tank 1, and the start and stop control of seawater injection can also be realized. The filter screen is fixed to the outlet end of the drain valve 12 with bolts, which can block particulate impurities from passing through and avoid clogging the pipeline. By disassembling the pipeline connected to the drain valve 12, the filter screen can be removed from the drain valve 12 for cleaning.

[0033] In use, first connect the device to an external power supply and controller. Power is supplied through the external power supply, and the device is controlled by the controller. Open the threaded cap 603 on the storage tank 601 and add an appropriate amount of disinfectant through the inlet. Confirm the amount of disinfectant added according to the metering mark on the observation window 602, then tighten the threaded cap 603. Open the flow control valve on the inlet pipe 11 to inject the seawater to be disinfected into the tank 1. Control the seawater injection volume based on the data from the level sensor 7. Close the flow control valve after reaching the target level. Start the servo motor 501 and metering pump 605 via the controller. The metering pump 605 draws the disinfectant from the storage tank 601 through the dispensing pipe 604 and injects it into the tank 1 through the dispensing pipe 606. Simultaneously, turn on the ultraviolet germicidal lamp inside the waterproof casing 2. The ultraviolet light penetrates the transparent lens 10 and acts on the seawater, working in conjunction with the disinfectant to achieve… Double disinfection is performed. During this process, the pH sensor 8 and temperature sensor 9 monitor the seawater status in real time. Simultaneously, the servo motor 501 operates, driving the rotating shaft 502 to rotate. The rotating shaft 502 drives the arc plate 503 to rotate, which in turn drives the rotating rod 505 to rotate. The rotating rod 505 then drives the stirring rod 507 to rotate, thus agitating the seawater. Since the small gear 506 meshes with the large gear 509, the rotation of the small gear 506 on the large gear 509 drives the stirring rod 507 to rotate, thereby agitating the seawater in multiple directions and making the seawater and the disinfectant mix more evenly. After disinfection is completed, the servo motor 501 and the ultraviolet germicidal lamp are turned off, and the drain valve 12 at the bottom of the tank 1 is opened to drain the treated seawater. This completes the entire process. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
