Description

Technical Field

[0001] This utility model relates to the field of sterilization devices, specifically a feed sterilization device. Background Technology

[0002] Tilapia is a highly adaptable fish that can survive and reproduce in various freshwater environments. Its flesh is delicious and nutritious, making it a favorite among consumers. In aquaculture, tilapia is highly sought after due to its rapid growth, short breeding cycle, and high yield.

[0003] When farming tilapia, their feed usually needs to be sterilized because the feed can be contaminated by various microorganisms, including bacteria and mold, during production, storage, and transportation. These microorganisms not only affect the quality of the feed but may also pose a threat to the health of the tilapia.

[0004] Existing feed sterilization devices generally use ultraviolet light for sterilization. However, during production and observation, it has been found that ultraviolet light mainly sterilizes the feed within the irradiated area. If the feed accumulates, it becomes difficult to effectively sterilize the feed inside, which reduces the sterilization effect of the device.

[0005] Therefore, a feed sterilization device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, a feed sterilization device includes a tank 1. The top of the tank 1 has a feed inlet 12; the middle of the tank 1 has a discharge outlet 13; a motor 14 is fixedly connected to the bottom of the tank 1; a rotating shaft 15 is fixedly connected to the output end of the motor 14; multiple stirring blades 16 are fixedly connected to the middle of the rotating shaft 15; a heating plate 19 is fixedly connected to the top of the inner wall of the tank 1; the bottom of the heating plate 19 is perforated; an air inlet pipe 18 is connected to the top of the heating plate 19; the air inlet pipe 18 and the tank 1 are through-connected; a pressure relief valve 17 is installed on the top of the tank 1; during operation, feed can be poured into the tank 1 through the feed inlet 12, and then the motor 14 can be started simultaneously, driving the rotating shaft 15 to rotate... The stirring blade 16 rotates and mixes the feed. After the feed is added, the valve at the feed inlet 12 can be closed. Then, a hot air blower can be connected to the air inlet pipe 18 so that the hot airflow enters the heating plate 19 through the air inlet pipe 18. The airflow will then spray out from the bottom of the heating plate 19 and enter the interior of the tank 1. The hot air will heat the feed in the tank 1, and the feed will be sterilized in a high-temperature environment. If the air pressure in the tank 1 is too high, the pressure relief valve 17 will release the pressure. Finally, the sterilized feed can be taken out by opening the valve at the discharge port 13. Through the combined action of the stirring blade 16 and the heating plate 19, the feed inside the tank 1 is continuously stirred and heated and sterilized by the hot airflow, so as to achieve uniform sterilization of the feed and reduce sterilization dead zones caused by feed accumulation.

[0026] Please see Figures 2 to 4 As shown, a baffle 2 is fixedly connected to the bottom of the heating plate 19; multiple fixing holes 22 are opened in the middle of the baffle 2; a pair of elastic plates 23 are fixedly connected to the inner wall of the fixing holes 22; when the feed enters the tank 1 through the feed inlet 12, and when the stirring blade 16 stirs and mixes the feed, the feed will diffuse inside the tank 1. When the feed diffuses, it will move closer to the heating plate 19, and the baffle 2 will block these feeds, reducing the amount of feed entering the heating plate 19. When the airflow is sprayed out from the surface of the heating plate 19, one side of the elastic plate 23 on the surface of the baffle 2 will deform and expand outward under the action of the airflow (e.g. Figure 3 and Figure 4 As shown, the airflow can pass through the fixing hole 22 and heat the feed. When there is no airflow coming out of the heating plate 19, the adjacent elastic plates 23 will recover under their own elasticity and stick to each other. That is, the elastic plates 23 will seal the fixing hole 22, reducing the amount of feed entering the baffle 2 through the fixing hole 22. Through the cooperation of the baffle 2 and the elastic plates 23, the baffle 2 and the elastic plates 23 will protect the heating plate 19 and reduce the contamination of the heating plate 19 by the feed.

[0027] Please see Figure 3 and Figure 4As shown, an elastic rope 3 is fixedly connected to the inner wall of the elastic plate 23; the elastic rope 3 and the inner wall of the baffle 2 are both fixedly connected; when airflow is ejected from the surface of the heating plate 19, one side of the elastic plate 23 will deform under the action of the airflow, and the elastic rope 3 will be in a stretched state. When the device stops heating, the elastic rope 3 will apply additional elastic force to the elastic plate 23, so that the elastic plate 23 will quickly return to its original position and block the fixing hole 22, reducing the amount of feed entering the baffle 2 due to the opening of the fixing hole 22.

[0028] Please see Figure 2 As shown, multiple pull ropes 4 are fixed to the inner wall of the tank 1; a filter pad 42 is fixed to the end of the pull rope 4; the filter pad 42 is located at the top of the rotating shaft 15; after the feed enters the tank 1 through the feed inlet 12, it will pass through the filter pad 42 and be filtered out by the filter pad 42, thereby realizing the filtration and purification of the feed by the device, which is convenient for subsequent processing of the feed.

[0029] Please see Figure 2 and Figure 5 As shown, a support plate 5 is fixedly connected to the top of the rotating shaft 15; multiple spheres 52 are rotatably connected to the middle of the support plate 5; multiple elastic blocks 53 are fixedly connected to the surface of the spheres 52; the filter pad 42 will accumulate impurities inside due to long-term filtration of feed. When the rotating shaft 15 rotates, it will drive the support plate 5 and the spheres 52 to move together. The spheres 52 will then come into contact with the filter pad 42 and rotate. When the spheres 52 rotate, the elastic blocks 53 will come into contact with the filter pad 42. The filter pad 42 will shake under the squeezing action of the elastic blocks 53, so that the impurities inside the filter pad 42 will be redistributed under the shaking action, reducing the possibility of blockage inside the filter pad 42.

[0030] Please see Figure 5 As shown, a plurality of protruding rods 6 are fixedly connected to the middle of the support plate 5; a plurality of bristles 62 are fixedly connected to the top of both the support plate 5 and the protruding rods 6; when the rotating shaft 15 rotates, it will drive the support plate 5 and the protruding rods 6 to rotate together, and when the support plate 5 and the protruding rods 6 rotate, they will also drive the bristles 62 on their tops to rotate together (the bristles 62 on the top of the support plate 5 are not shown in the figure). The bristles 62 will clear the impurities inside the filter pad 42 and reduce the clogging of the filter pad 42 caused by the accumulation of impurities.

[0031] Working principle: Feed is poured into the tank 1 through the feed inlet 12. Simultaneously, the motor 14 is started, driving the rotating shaft 15 to rotate the stirring blades 16 and mix the feed. After the feed is added, the valve at the feed inlet 12 is closed. Then, a hot air blower is connected to the air inlet pipe 18, allowing hot air to enter the heating plate 19. The airflow then exits from the bottom of the heating plate 19 and enters the tank 1, heating the feed inside. The feed is sterilized under high temperature. If the pressure inside the tank 1 is too high, the pressure relief valve 17 will release the pressure. Finally, the sterilized feed... Feed can be removed by opening the valve at the discharge port 13. When the feed enters the tank 1 through the inlet 12, and when the stirring blades 16 mix the feed, the feed will diffuse inside the tank 1. As the feed diffuses, it will move closer to the heating plate 19, and the baffle 2 will block this feed, reducing the amount of feed entering the heating plate 19. When airflow is ejected from the surface of the heating plate 19, one side of the elastic plate 23 on the surface of the baffle 2 will deform and expand outward under the action of the airflow, allowing the airflow to pass through the fixing hole 22 and heat the feed. When there is no airflow ejected from the heating plate 19, the adjacent elastic plate 23 will deform on its own. Under elastic action, the elastic plate 23 recovers and adheres tightly to each other, meaning the elastic plate 23 will seal the fixing hole 22, reducing the amount of feed entering the baffle 2 through the fixing hole 22; when airflow is ejected from the surface of the heating plate 19, one side of the elastic plate 23 will deform under the action of the airflow, at which time the elastic rope 3 will be in a stretched state. When the device stops heating, the elastic rope 3 will apply additional elastic force to the elastic plate 23, causing the elastic plate 23 to quickly return to its original position and block the fixing hole 22; after the feed enters the tank 1 through the feed inlet 12, it will pass through the filter pad 42 and be filtered out by the filter pad 42, realizing the filtration and purification of the feed by the device; the filter pad Filtering feed for a long time will cause impurities to accumulate inside. When the rotating shaft 15 rotates, it will drive the support plate 5 and the ball 52 to move together. The ball 52 will come into contact with the filter pad 42 and rotate. When the ball 52 rotates, it will cause the elastic block 53 to come into contact with the filter pad 42. The filter pad 42 will shake under the squeezing action of the elastic block 53, causing the impurities inside the filter pad 42 to redistribute under the shaking action. When the rotating shaft 15 rotates, it will drive the support plate 5 and the protruding rod 6 to rotate together. When the support plate 5 and the protruding rod 6 rotate, they will also drive the brush bristles 62 on their top to rotate together. The brush bristles 62 will clear the impurities inside the filter pad 42.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
