Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a filtration device for aquaculture. Background Technology

[0002] Aquaculture is the practice of humans using aquatic waters available for aquaculture (including planting) to raise aquatic economic animals and plants according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, using aquaculture technology and facilities. Aquaculture filtration devices are key equipment for maintaining stable water quality, effectively removing suspended solids, organic matter, harmful substances (such as ammonia nitrogen and nitrite) and microorganisms from the water, thereby providing a healthy environment for the farmed organisms.

[0005] Most existing filter cartridges are inconvenient to disassemble and assemble, resulting in numerous disassembly and assembly steps when cleaning the filter cartridges. Utility Model Content

[0006] The purpose of this invention is to provide a filtration device for aquaculture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a filtration device for aquaculture, comprising a filter box, an inlet pipe on one side of the filter box, an outlet pipe on the other side of the filter box, a filter cylinder inside the filter box, an installation structure inside the filter box, the installation structure comprising a fixing seat, a fixing seat inside the filter box, a spring inside the fixing seat, a connecting column inside the fixing seat and the connecting column being connected to the spring, a connecting seat at the end of the connecting column, a pressure frame fixed on the connecting seat, a clamping plate connected to the fixing seat, and a limit block fixed on the fixing seat.

[0008] Preferably, the fixing seat has a sealing ring inside, and the connecting post passes through the middle of the sealing ring.

[0009] Preferably, a pressure block is fixed inside the pressure frame.

[0010] Preferably, a spring connector is fixed on the pressure block.

[0011] Preferably, a limit rod is fixed inside the pressure frame.

[0012] Preferably, the limiting block is frame-shaped, and the locking plate is inserted into the limiting block.

[0013] Preferably, when the card plate abuts against the surface of the connecting seat, the spring is in a state of tension.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When installing the filter cartridge, insert it into the pressure frame, which will pre-fix the cartridge. Then, push the connecting seat to align the filter cartridge with the inlet pipe. Place the retaining plate against the connecting seat, pushing it to ensure the filter cartridge is firmly pressed against the filter box surface. The retaining plate can be limited by the internal limit block, facilitating easy installation. To disassemble, rotate the retaining plate to move it out of the limit block, separating the filter cartridge from the outlet pipe for easy removal. This installation structure facilitates easy assembly and disassembly of the filter cartridge, making subsequent maintenance more convenient. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a filtration device for aquaculture, including a filter box 1, an inlet pipe 2 fixed on one side of the filter box 1, an outlet pipe 3 fixed on the other side of the filter box 1, a filter cylinder 4 assembled inside the filter box 1, and the filter cylinder 4 being connected to the inlet pipe 2. An installation structure 5 is provided inside the filter box 1.

[0023] Wastewater enters the filter cartridge 4 through the inlet pipe 2, where impurities are filtered out. After filtration, the wastewater enters the filter box 1 and is then extracted through the outlet pipe 3, thus achieving the filtration of aquaculture water.

[0024] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides a filtration device for aquaculture. The installation structure 5 includes a fixed base 51. The fixed base 51 is fixed to the left side of the filter box 1 by bolts. A spring 52 is installed inside the fixed base 51. A connecting column 53 is installed inside the fixed base 51. The connecting column 53 and the fixed base 51 are horizontally slidably connected. One end of the connecting column 53 is fixed to one end of the spring 52. The other end of the spring 52 is fixed inside the fixed base 51. A connecting base 54 is fixed to the other end of the connecting column 53. A pressure frame 55 is installed on the connecting base 54. A clamping plate 56 is rotatably connected to the fixed base 51. A limit block 57 is fixed on the fixed base 51.

[0025] The fixed base 51 is provided with a sealing ring 58 inside, and the connecting post 53 passes through the middle of the sealing ring 58, effectively preventing water from entering the connecting post 53 and the fixed base 51;

[0026] A pressure block 59 is fixed inside the pressure frame 55 to limit the filter cartridge 4 installed inside the pressure frame 55. A spring connector 510 is fixed on the pressure block 59. When the pressure frame 55 pushes the filter cartridge 4, the spring connector 510 will be deformed by force. Pushing the filter cartridge 4 makes the filter cartridge 4 better connected to the water inlet pipe 2, and the filter cartridge 4 can be pressed on the surface of the filter box 1, which improves the sealing performance. A limit rod 511 is fixed inside the pressure frame 55 to limit the function of the spring connector 510.

[0027] The limiting block 57 is frame-shaped, and the locking plate 56 is inserted into the limiting block 57 to prevent the locking plate 56 from tilting.

[0028] When the clamping plate 56 abuts against the surface of the connecting seat 54, the spring 52 is under tension and pulls the pressure frame 55 to facilitate the disassembly of the filter cartridge 4.

[0029] When installing the filter cartridge 4, insert the filter cartridge 4 into the pressure frame 55. The pressure frame 55 will pre-fix the filter cartridge 4. Then push the connecting seat 54 to make the pressure frame 55 slide horizontally, thereby driving the connecting seat 54 and causing the connecting column 53 to slide along the inner side of the fixed seat 51. At this time, the spring 52 is stretched and generates elastic force, so that the filter cartridge 4 is connected to the water inlet pipe 2. Then rotate the clamping plate 56 and press the clamping plate 56 against the connecting seat 54, thereby pushing the connecting seat 54 so that the filter cartridge 4 can be tightly pressed against the surface of the filter box 1. The rotated clamping plate 56 can limit the connecting seat 54 and simultaneously lock into the limiting block 57, thereby limiting the clamping plate 56 to achieve the beneficial effect of convenient installation of the filter cartridge 4.

[0030] During disassembly, rotate the clamping plate 56 to move it out of the limiting block 57, thereby releasing the limiting of the connecting seat 54. Under the action of the spring 52, pull the connecting column 53 to make the pressure frame 55 slide to the left, thereby driving the filter cartridge 4 to separate from the water outlet pipe 3, so as to achieve the beneficial effect of convenient disassembly. The filter cartridge 4 is disassembled and assembled through the installation structure 5, making the disassembly and assembly of the filter cartridge 4 convenient and making subsequent maintenance of the filter cartridge 4 more convenient.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
