Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a heating device for aquaculture water. Background Technology
[0002] Most aquatic animals are poikilothermic, meaning their body temperature changes with the water temperature. Suitable water temperatures can increase their metabolic rate and promote enzyme activity, thereby accelerating the absorption and conversion of nutrients. Therefore, during the lower temperatures of spring, autumn, and winter, it is necessary to heat the water in the aquaculture ponds to raise the water temperature to a suitable level.
[0003] Because the water quality in aquaculture needs to be kept stable, it is not advisable to exchange it with external water. Therefore, current aquaculture heating primarily relies on heat exchange. When arranging heat exchange pipes, based on the principle that hot water rises and cold water sinks, and the need for even heating, the heating pipes are generally placed in the center of the bottom of the tank or evenly spread across the entire bottom. Simply placing the heating pipes at the bottom of the tank easily leads to the sedimentation and adhesion of food residue, aquatic animal feces, and metabolic waste onto the pipes. Over time, these organic substances not only corrode the pipe walls, causing rust, but also rot and breed bacteria. Furthermore, these heating pipes, located in the center of the tank, are difficult to clean.
[0004] Therefore, it is necessary to design a heating device for aquaculture water that not only has a reasonable arrangement of heating pipes, but also effectively reduces the amount of organic matter adhering to the central heating pipes mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a heating device for aquaculture water to solve the problems described in the background art.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A heating device for aquaculture ponds includes multiple heating pipes located at the bottom of the pond. These pipes extend along the front-to-back direction of the pond. Multiple support bases are detachably mounted on the bottom of each heating pipe, separating the bottom of the pipe from the bottom of the pond. An inlet pipe is located at the front end of the pond, and an outlet pipe is located at the rear end. The front ends of the heating pipes are connected to the inlet pipe via adapter pipes and connecting pipes located at the front end of the pond, and the rear ends of the heating pipes are connected to the outlet pipe via adapter pipes and connecting pipes located at the rear end of the pond. A shielding assembly is provided on each heating pipe. The shielding assembly includes a first baffle, a second baffle, and a third baffle extending along the front-to-back direction of the pond. The bottom of the first baffle is detachably mounted via a connecting assembly. Installed on the heating pipe, the first baffle is obliquely positioned above the heating pipe, the second baffle is obliquely positioned with its top connected to the bottom of the first baffle and positioned above the heating pipe, and the third baffle is obliquely positioned with its bottom connected to the top of the first baffle and covering the top of the second baffle. Multiple lower water outlets are provided at the connection between the second baffle and the first baffle, spaced apart along the front-to-back direction of the aquaculture pond. Multiple upper water outlets are provided at the connection between the first baffle and the third baffle, spaced apart along the front-to-back direction of the aquaculture pond. The upper water outlets and lower water outlets are not in the same vertical direction. The top of the third baffle extends obliquely upwards, covering the top of the upper water outlets. The lengths of the first baffle, the second baffle, and the third baffle are all greater than the length of the heating pipe and all completely cover the top of the heating pipe.
[0008] When using the above scheme, hot water is introduced through the inlet pipe. The hot water then passes through the transfer pipe and connecting pipe into the heating pipe. Multiple heating pipes are laid along the bottom of the aquaculture tank in a front-to-back direction to ensure a more uniform heat exchange area. The pipe walls heat the aquaculture water surrounding the heating pipes through heat conduction. The heated aquaculture water rises through the lower outlet hole to the area held by the first, second, and third baffles, then rises through the upper outlet hole to the area held by the first and third baffles, and finally rises along the bottom of the third baffle into the aquaculture tank above the shielding components, thus heating the aquaculture water in the entire tank. By setting up lower and upper outlet holes, the heated aquaculture water can be quickly released into the entire aquaculture tank, avoiding large temperature differences caused by overheating at the bottom and coldness in the middle and upper parts of the tank, and preventing aquatic animals from becoming diseased due to large temperature differences.
[0009] When the organic matter above the shielding component sinks, it is mostly blocked by the first and third baffles, and slides down along the top surface of the first and third baffles, avoiding the heating pipe. If it can escape the shielding of the first and third baffles and enter the lower part through the upper water outlet, it will also be blocked by the second baffle, and slide down along the top surface of the second baffle, avoiding the heating pipe.
[0010] By setting up support bases, the heating pipes can be effectively lifted, preventing the organic matter at the bottom from coming into contact with the heating pipes.
[0011] A further technical solution is that the connecting assembly includes a connecting rod, an upper clamping sleeve, and a lower clamping sleeve. One end of the connecting rod is fixedly connected to the bottom of the first baffle, and the other end of the connecting rod is fixedly connected to the upper clamping sleeve. The lower clamping sleeve is detachably installed on the upper clamping sleeve to clamp and form a clamping space that matches the cross-section of the heating pipe. The heating pipe is fixedly clamped in the clamping space.
[0012] When using the above solution, the design of the connecting component facilitates the disassembly and assembly of the shielding component, while also facilitating the adjustment of the installation angle of the shielding component and reducing the manufacturing precision of the shielding component.
[0013] A further technical solution is that, after the shielding components are installed, the angle between the first baffle and the horizontal plane is 28-32°, the angle between the bottom surface of the second baffle and the bottom surface of the first baffle is 118-122°, and the angle between the bottom surface of the third baffle and the bottom surface of the first baffle is 118-122°.
[0014] When using the above solution, the angle design can simultaneously achieve the effect of blocking falling organic matter and compressing the height of the blocking component.
[0015] A further technical solution is that, after the shielding components are installed, the angle between the first baffle and the horizontal plane is 29.8 to 30.2°, the angle between the bottom surface of the second baffle and the bottom surface of the first baffle is 119.8 to 120.2°, and the angle between the bottom surface of the third baffle and the bottom surface of the first baffle is 119.8 to 120.2°.
[0016] When using the above solution, the angle design can simultaneously achieve the effect of blocking falling organic matter and compressing the height of the blocking component.
[0017] A further technical solution is that the support base is a cuboid block with a flat bottom, and the top of the cuboid block has an embedding groove for embedding the heating pipe.
[0018] Using the above method facilitates the stable placement and disassembly of heating pipes.
[0019] A further technical solution is that the first baffle, the second baffle, the third baffle, the connecting component, and the support base are all made of rigid plastic.
[0020] When using the above solution, rigid plastics can effectively prevent rust and can be easily processed to produce a smoother surface, preventing the adhesion of organic matter.
[0021] A further technical solution is that the bottom horizontal height of the third baffle should be lower than the bottom horizontal height of the drain outlet.
[0022] Using the above solution can effectively prevent organic matter that slides down from the third baffle from falling onto the heating pipe through the lower water outlet.
[0023] A further technical solution is that the rigid plastic is rigid nylon plastic.
[0024] The beneficial effects of this utility model are as follows:
[0025] 1. Uniform heat exchange: Multiple heating pipes are laid along the front and back direction at the bottom of the breeding pond, making the heat exchange area more uniform and improving heating efficiency.
[0026] 2. Temperature difference control: By setting up bottom and top water outlets, the heated aquaculture water is quickly released into the entire aquaculture pond, avoiding the bottom of the aquaculture water from being too hot while the middle and upper parts are relatively cold, reducing the temperature difference and preventing aquatic animals from becoming sick due to temperature differences.
[0027] 3. Organic matter blocking: The blocking components and baffles are designed to effectively block the sinking organic matter, preventing it from contacting the heating pipes and protecting the heating system from damage.
[0028] 4. Heating pipe support: The support base design effectively lifts the heating pipe, further preventing the organic matter at the bottom from coming into contact with the heating pipe, thus keeping the heating pipe clean and operating efficiently.
[0029] 5. Easy to disassemble and maintain: The design of the connecting components facilitates the disassembly and angle adjustment of the shielding components, reduces the manufacturing precision requirements of the shielding components, and makes maintenance and management convenient.
[0030] 6. Balancing height and effectiveness: The angled design not only blocks falling organic matter but also reduces the height of the shielding components, making the system more compact and efficient. Attached Figure Description
