A biofilter for aquaculture

Abstract

This utility model belongs to the field of aquaculture equipment, specifically a biological filter for aquaculture, including a tank. The top of the tank is fixedly connected to an inlet, and one side of the tank is fixedly connected to an outlet. A filtration mechanism is installed inside the tank, including a packing frame that is rotatably fitted inside the tank. By setting up the filtration mechanism and adding molecular sieve packing to the packing frame, when aquaculture water is fed into the tank through the inlet, the impact of the water flow causes the fan blades to rotate, which in turn drives the shaft to rotate. The shaft then rotates the packing frame, which in turn drives the packing to rotate via protrusions and baffles, causing the packing to tumble inside the packing frame. This ensures uniform contact between the aquaculture water and the packing, guaranteeing the treatment effect of the aquaculture water and effectively improving the treatment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, specifically a biological filter for aquaculture. Background Technology

[0002] Biofilters for aquaculture are a core component of recirculating aquaculture systems. They maintain water quality stability by degrading ammonia nitrogen and nitrite through nitrifying bacteria. Types include submerged, tower, rotating biological disc, and trickle filters. Biofilters can significantly improve aquaculture efficiency, ensure the health of organisms, and are a key technology for achieving sustainable aquaculture.

[0003] In existing technologies, biofilters for aquaculture are core components of circulating water systems. However, during use, the packing material remains stationary in the treatment tank, making it difficult for the packing material to contact the water being treated evenly. This reduces the effectiveness of water treatment and thus lowers the efficiency of water treatment, thereby affecting the quality of water used in aquaculture. Therefore, a biofilter for aquaculture is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, where the packing material inside aquaculture biofilters is in a static state, making it difficult for the packing material to contact the water being treated evenly, thus reducing the water treatment effect and efficiency, this invention proposes a biofilter for aquaculture.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a biological filter for aquaculture, including a tank, with an inlet fixedly connected to the top of the tank, an outlet fixedly connected to one side of the tank, and a filtration mechanism provided inside the tank.

[0006] The filtration mechanism includes a packing frame, which is rotatably fitted inside the tank. Several protrusions are fixedly installed inside the packing frame. A rotating shaft is fixedly connected inside the packing frame. A water guide frame is rotatably fitted on the surface of the rotating shaft. A sleeve is fixedly connected to the bottom of the water guide frame. The sleeve is rotatably fitted on the surface of the rotating shaft. Several baffles are fixedly connected to the surface of the sleeve. Several fan blades are fixedly installed on the surface of the rotating shaft. A water guide plate is fixedly installed inside the tank and is located between the water guide frame and the packing frame.

[0007] Preferably, a bracket is fixedly installed inside the tank, and the surface of the bracket is slidably connected to the bottom of the packing frame.

[0008] Preferably, a first slider is fixedly installed at the bottom of the packing frame, and a first groove is formed on the surface of the bracket, with the first slider slidably connected inside the first groove.

[0009] Preferably, a second slider is fixedly installed inside the tank, and a second groove is formed on the surface of the packing frame, with the surface of the second slider slidably connected to the inner cavity of the second groove.

[0010] Preferably, a positioning block is fixedly installed on the surface of the rotating shaft, and a positioning groove is opened in the inner cavity of the water guide frame, with the positioning block rotatably connected inside the positioning groove.

[0011] Preferably, a water baffle is fixedly sleeved on the surface of the rotating shaft, and the water baffle is used in conjunction with the water guide frame.

[0012] Preferably, the tank body is internally fixedly connected with several fixing rods, one end of each fixing rod being fixedly connected to the surface of the water guide frame.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, by setting up a filtration mechanism and adding molecular sieve packing material to the packing frame, when aquaculture water is sent into the tank through the inlet, the impact of the water flow causes the fan blades to rotate, the rotating shaft to rotate, the packing frame to rotate, and the packing frame to rotate the packing material through the protrusions, and the packing material is blocked by the baffle, so that the packing material flips inside the packing frame, thereby making the aquaculture water and the packing material in uniform contact, so as to ensure the treatment effect of aquaculture water and effectively improve the treatment efficiency of aquaculture water;

[0015] 2. By setting up a water guide frame and a water guide plate, this utility model can easily guide the aquaculture water to the packing frame, so that the aquaculture water and the packing can be in complete contact, avoiding the situation where the aquaculture water and the packing are not in complete contact. By setting up a water baffle, the aquaculture water can be prevented from passing between the sleeve and the rotating shaft and failing to contact the packing. Attached Figure Description

[0022] 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.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a biological filter for aquaculture. (Refer to...) Figure 1 , Figure 2 and Figure 3 A biological filter for aquaculture includes a tank 1, with an inlet 101 fixedly connected to the top of the tank 1, an outlet 102 fixedly connected to one side of the tank 1, and a filtration mechanism 2 installed inside the tank 1.

[0025] The filtration mechanism 2 includes a packing frame 21, which is rotatably fitted inside the tank 1. Several protrusions 22 are fixedly installed inside the packing frame 21. A rotating shaft 23 is fixedly connected inside the packing frame 21. A water guide frame 25 is rotatably fitted on the surface of the rotating shaft 23. A sleeve 26 is fixedly connected to the bottom of the water guide frame 25. The sleeve 26 is rotatably fitted on the surface of the rotating shaft 23. Several baffles 27 are fixedly connected to the surface of the sleeve 26. Several fan blades 24 are fixedly installed on the surface of the rotating shaft 23. A water guide plate 28 is fixedly installed inside the tank 1 and is located between the water guide frame 25 and the packing frame 21. The packing material in the packing frame 21 is a molecular sieve, which can selectively adsorb carbon dioxide in aquaculture water to adjust the pH balance of aquaculture water.

[0026] When aquaculture water treatment is required, the aquaculture water is fed into the tank 1 through the inlet 101. When the aquaculture water enters, the impact of the aquaculture water causes the fan blade 24 to drive the rotating shaft 23 to rotate. The rotating shaft 23 drives the packing frame 21 to rotate. The packing frame 21 moves the packing through the protrusion 22, and the blocking of the baffle 27 causes the packing to flip in the packing frame 21. The aquaculture water is guided into the packing frame 21 through the water guide frame 25 and the water guide plate 28, so that the aquaculture water and the packing are in full contact to ensure the treatment effect of the aquaculture water.

[0027] Reference Figure 3 and Figure 4 A bracket 2101 is fixedly installed inside the tank body 1, and the surface of the bracket 2101 is slidably connected to the bottom of the packing frame 21. A first slider 2102 is fixedly installed at the bottom of the packing frame 21, and a first groove 2103 is opened on the surface of the bracket 2101. The first slider 2102 is slidably connected inside the first groove 2103. By setting the bracket 2101 inside the tank body 1, the bracket 2101 can support the position of the packing frame 21. The first slider 2102 is slidably connected inside the first groove 2103 so that the bracket 2101 stabilizes the position of the bottom of the packing frame 21 through the first groove 2103 and the first slider 2102, while preventing the rotating shaft 23 from tilting or shifting.

[0028] Reference Figure 3 and Figure 4 The tank body 1 has a second slider 2104 fixedly installed inside, and the surface of the packing frame 21 has a second groove 2105. The surface of the second slider 2104 is slidably connected to the inner cavity of the second groove 2105. By sliding the second slider 2104 inside the second groove 2105, the position of the upper end of the packing frame 21 can be effectively stabilized, and the packing frame 21 can be prevented from tilting or shifting, so as to ensure the stability of the position of the packing frame 21.

[0029] Reference Figure 3 and Figure 4 A positioning block 2301 is fixedly installed on the surface of the rotating shaft 23, and a positioning groove 2302 is opened in the inner cavity of the water guide frame 25. The positioning block 2301 is rotatably connected to the inside of the positioning groove 2302. When the rotating shaft 23 rotates, the positioning block 2301 is rotatably connected to the inside of the positioning groove 2302 so that the water guide frame 25 stabilizes the position of the upper end of the rotating shaft 23 through the positioning block 2301 and the positioning groove 2302, avoiding tilting or offset of the rotating shaft 23, so that the water flow through the fan blade 24 can drive the rotating shaft 23 to rotate stably.

[0030] Reference Figure 3 and Figure 4A baffle plate 2303 is fixedly sleeved on the surface of the rotating shaft 23. The baffle plate 2303 is used in conjunction with the water guide frame 25. By setting the baffle plate 2303 on the surface of the rotating shaft 23, water flow can be effectively prevented from entering between the rotating shaft 23 and the sleeve 26, so as to prevent the aquaculture water from not being able to contact the packing after passing between the rotating shaft 23 and the sleeve 26.

[0031] Reference Figure 2 and Figure 3 Several fixing rods 2501 are fixedly connected inside the tank body 1, and one end of each fixing rod 2501 is fixedly connected to the surface of the water guide frame 25. By installing the fixing rods 2501 inside the tank body 1 and fixing one end of the fixing rods 2501 to the surface of the water guide frame 25, the position of the water guide frame 25 inside the tank body 1 is effectively stabilized. By fixing the position of the water guide frame 25, the stability of the position of the water guide frame 25 is ensured, and the water guide frame 25 is prevented from affecting the position and rotation of the rotating shaft 23.

[0032] Working principle: When aquaculture water treatment is required, the aquaculture water is fed into the tank 1 through the inlet 101. Upon entry, the impact of the water causes the fan blades 24 to rotate the shaft 23. The position of the guide frame 25 is fixed by the fixing rod 2501, which, through the positioning block 2301 and positioning groove 2302, stabilizes the position of the shaft 23, preventing tilting or offset. This allows the shaft 23 to rotate the packing frame 21. The bottom of the packing frame 21 is supported by the bracket 2101, preventing lateral displacement of the packing frame 21 on the surface of the bracket 2101 via the first slider 2102 and the first sliding groove 2103. The second slider 2104 is slidably connected inside the second sliding groove 2105 for effective stability. The position of the packing frame 21 allows the packing material to move via the protrusion 22, and the baffle 27 causes the packing material to rotate within the packing frame 21. The water guide frame 25 and the water guide plate 28 guide the aquaculture water into the packing frame 21, ensuring sufficient contact between the water and the packing material and guaranteeing the treatment effect. Furthermore, the baffle plate 2303 on the surface of the rotating shaft 23 effectively prevents water from entering between the rotating shaft 23 and the sleeve 26, preventing the aquaculture water from failing to contact the packing material after passing between them. Moreover, by using a molecular sieve as the packing material, the molecular sieve can selectively adsorb carbon dioxide in the aquaculture water, adjusting the pH balance and preventing incomplete treatment that could negatively impact aquaculture.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
