Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a small shed device for waste heat recovery from the tailwater of grouper farming. Background Technology

[0002] Wastewater heat recovery is a technology that reuses the heat in high-temperature wastewater discharged from industrial, agricultural, or municipal sectors. In aquaculture, traditional heating equipment such as boilers and heat pumps can overcome geographical and seasonal limitations to achieve "off-season farming," but the high cost of water and electricity is a major factor restricting its development. By recovering heat from high-temperature aquaculture wastewater to heat low-temperature clean seawater, and then mixing it with seawater heated by heating equipment, grouper can still grow normally in natural water temperatures below 10°C.

[0003] Currently, waste heat recovery from tailwater is mainly achieved through heat exchange equipment. Tailwater usually contains impurities, which are discharged directly after the tailwater undergoes heat exchange, resulting in a certain degree of pollution. Furthermore, after prolonged use, impurities can easily adhere to the inside of the heat exchanger, forming scale, which affects the heat exchange effect. Disassembling and cleaning the heat exchanger is also quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide a small shed device for recovering waste heat from the tailwater of grouper farming, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small shed device for recovering waste heat from the aquaculture wastewater of grouper, comprising: a base plate, a protective shed installed on the top of the base plate, and an installation frame, further comprising: a sliding groove opened on the inner wall of the top of the installation frame, an adjusting component installed on one side of the outer wall of the installation frame, and fixed frames installed at both ends of the bottom of the adjusting component, a wastewater tank and a cold water tank respectively rotatably installed on the inner walls of the two fixed frames, and a flipping component installed on one side of the outer wall of the installation frame, a heat exchange component installed on the top outer wall of the base plate, and toothed rings installed at one end of both the wastewater tank and the cold water tank, and guide frames installed on one side of the outer wall of both the wastewater tank and the cold water tank.

[0006] Both the tailwater tank and the cold water tank have openings on their outer walls.

[0007] The adjustable pitch assembly includes a motor, a bidirectional threaded rod connected to one end of the motor output shaft, and a moving block screwed to both ends of the bidirectional threaded rod.

[0008] The flipping assembly includes a connecting plate, an electric push rod mounted on the top of the connecting plate, a sliding frame mounted on the bottom of the piston rod of the electric push rod, and a rack slidably connected to both ends of the inner wall of the sliding frame.

[0009] The two racks respectively mesh with the two toothed rings.

[0010] The heat exchange assembly includes a base, multiple heat exchange plates evenly distributed on the top of the base, sealing plates installed on both sides of the heat exchange plates, heat exchange filters located at both ends of the heat exchange plates, and sealing gaskets installed on the outer wall of one side of the sealing plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a waste heat recovery shed device for grouper aquaculture wastewater. The heat exchange components located inside the wastewater tank and cold water tank also have a filtration function, which can filter both the wastewater and cold water flowing in the wastewater tank and cold water tank. It can filter out impurities in the wastewater, improving the environmental protection of wastewater discharge.

[0014] 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 protection scope of the present utility model.

[0015] Please see Figure 1-7 This utility model provides a waste heat recovery shed device for aquaculture wastewater, comprising: a base plate 1, a protective shed 2 installed on the top of the base plate 1, and a mounting frame 3. It also includes: a sliding groove 4 on the inner wall of the top of the mounting frame 3; an adjusting component 5 installed on one outer wall of the mounting frame 3; and fixed frames 6 installed at both ends of the bottom of the adjusting component 5. A wastewater tank 7 and a cold water tank 8 are rotatably installed on the inner walls of the two fixed frames 6, respectively. A flipping component 9 is installed on one outer wall of the mounting frame 3. A heat exchange component 10 is installed on the outer wall of the top of the base plate 1. A toothed ring 11 is installed at one end of both the wastewater tank 7 and the cold water tank 8. A guide frame 12 is installed on one outer wall of both the wastewater tank 7 and the cold water tank 8. Both the wastewater tank 7 and the cold water tank 8 have openings on their outer walls.

[0016] It should be noted that the tailwater tank 7 and the cold water tank 8 can be connected to the external tailwater pipe and cold water pipe respectively. The tailwater and cold water flow into the tailwater tank 7 and the cold water tank 8 respectively. The two ends of the heat exchange component 10 extend into the tailwater tank 7 and the cold water tank 8 respectively. The heat exchange component 10 can play the role of heat exchange, transferring the heat in the tailwater to the cold water, and recovering the waste heat of the tailwater. After waste heat recovery, the temperature of the cold water in the cold water tank can be raised from 5℃ to 16-20℃. When using this 16-20℃ cold water for fish farming, since the optimal growth temperature for grouper is 25-30℃, the 16-20℃ cold water needs to be mixed with externally supplied 50-60℃ hot water to obtain 25-30℃ warm water for the fish pond. If mixing is feasible, a mixing pipe should be installed, with one end connected to both the 16-20℃ cold water pipe and the 50-60℃ hot water pipe, and the other end connected to the fish pond inside the fish shed. A temperature sensor should be installed in the mixing pipe near the fish pond, and water flow regulators should be installed in both the cold and hot water pipes. The device is then electrically connected to both the temperature sensor and the water flow regulator. When the temperature sensor detects that the water temperature in the mixing pipe is below 25°C, the water flow regulator in the cold water pipe is controlled to reduce the water flow, and the water flow regulator in the hot water pipe is controlled to increase the water flow. When the temperature sensor detects that the water temperature in the mixing pipe is above 30°C, the water flow regulator in the cold water pipe is controlled to increase the water flow, and the water flow regulator in the hot water pipe is controlled to reduce the water flow, thus achieving dynamic adjustment to ensure that the water temperature entering the fish pond is between 25-30°C. The specific models of the controller, temperature sensor, and water flow regulator can be selected by those skilled in the art according to their needs, which is a common technical means in this field and will not be described in detail here.

[0017] The portion of the heat exchange component 10 located within the tailwater tank 7 and the cold water tank 8 also has a filtration function. It can filter both the tailwater and cold water flowing within the tailwater tank 7 and the cold water tank 8, removing impurities from the tailwater and improving the environmental friendliness of the tailwater discharge. After a period of use, the tailwater tank 7 and the cold water tank 8 can be disconnected from the external water pipes. At this time, the distance between the tailwater tank 7 and the cold water tank 8 can be increased by adjusting the distance component 5, allowing the heat exchange component 10 to be fully exposed for easy cleaning and removal of the filtered impurities. Simultaneously, after the tailwater tank 7 and the cold water tank 8 are separated from the heat exchange component 10, the openings on their bodies are exposed. Then, by using the flipping component 9, the tailwater tank 7 and the cold water tank 8 can be rotated in the opposite direction, so that the openings of the tailwater tank 7 and the cold water tank 8 face downwards, facilitating the cleaning of scale on the inner walls of the tailwater tank 7 and the cold water tank 8. The cleaned scale can fall directly from the tailwater tank 7 or the cold water tank 8, which is convenient and quick.

[0018] In a preferred embodiment, the pitch adjustment assembly 5 includes a motor 501, a bidirectional threaded rod 502 connected to one end of the output shaft of the motor 501, and a moving block 503 screwed to both ends of the bidirectional threaded rod 502.

[0019] It should be noted that the motor 501 can drive the bidirectional threaded rod 502 to rotate, thereby causing the two moving blocks 503 to move away from or closer to each other.

[0020] In a preferred embodiment, the flipping assembly 9 includes a connecting plate 901, an electric push rod 902 mounted on the top of the connecting plate 901, a sliding frame 903 mounted on the bottom of the piston rod of the electric push rod 902, and racks 904 slidably connected to both ends of the inner wall of the sliding frame 903, with the two racks 904 respectively meshing with two toothed rings 11.

[0021] It should be noted that the electric push rod 902 can drive the sliding frame 903 to rise, which in turn drives the two racks 904 to rise, which in turn drives the two gear rings 11 to rotate in the opposite direction, which in turn drives the tailwater tank 7 and the cold water tank 8 to rotate in the opposite direction.

[0022] In a preferred embodiment, the heat exchange assembly 10 includes a base 1001, a plurality of heat exchange plates 1002 equidistantly distributed on the top of the base 1001, sealing plates 1003 installed on both sides of the heat exchange plates 1002, heat exchange filters 1004 disposed at both ends of the heat exchange plates 1002, and sealing gaskets 1005 installed on the outer wall of one side of the sealing plate 1003.

[0023] It should be noted that the heat exchange filters 1004 at both ends of the heat exchange plate 1002 can be placed in the tailwater tank 7 and the cold water tank 8 respectively. The two sealing plates 1003 can block the openings on the outer walls of the tailwater tank 7 and the cold water tank 8 respectively. The sealing gaskets 1005 can ensure the sealing of the openings. The water in the tailwater tank 7 and the cold water tank 8 undergoes heat exchange through the heat exchange plate 1002, and is filtered by the heat exchange filters 1004.

[0024] Working principle: The water systems of multiple fish farming sheds are connected in parallel. The water used for fish farming first enters the impurity sedimentation shed through the water pipes for sedimentation and purification, and then enters the waste heat recovery shed for waste heat recovery. The tailwater tank 7 and the cold water tank 8 can be connected to the external tailwater pipe and cold water pipe respectively. The heat exchange filters 1004 at both ends of the heat exchange plate 1002 can be placed in the tailwater tank 7 and the cold water tank 8 respectively. The two sealing plates 1003 can block the openings on the outer walls of the tailwater tank 7 and the cold water tank 8 respectively. The sealing gasket 1005 can ensure the sealing of the opening. The water in the tailwater tank 7 and the cold water tank 8 exchanges heat through the heat exchange plate 1002 and is filtered by the heat exchange filters 1004. After the waste heat is recovered, the 5-degree cold water is raised to 18 degrees and then mixed with the 50-60 degree hot water heated by the boiler. During the mixing process, a temperature sensor intelligently adjusts the temperature. The boiler and temperature sensor are considered prior art in this application, and their working principle and operation method will not be described in detail here. The system filters out impurities in the wastewater, improving the environmental friendliness of wastewater discharge. After a period of use, the wastewater tank 7 and cold water tank 8 can be disconnected from the external water pipes. At this time, the motor 501 can drive the bidirectional threaded rod 502 to rotate, thereby causing the two moving blocks 503 to move away from each other, and simultaneously causing the two racks 904 to move away from each other, so that the wastewater tank 7 and cold water tank 8 are separated from the heat exchange plate 1002, making it convenient to clean the heat exchange filter screen 1004 and ensure the filtration effect. The openings on the wastewater tank 7 and cold water tank 8 are exposed, and the electric push rod 902 can drive the sliding frame 903 to rise, thereby driving the two racks 904 to rise, thereby driving the two gear rings 11 to rotate in the opposite direction, and thus driving the wastewater tank 7 and cold water tank 8 to rotate in the opposite direction, so that the openings of the wastewater tank 7 and cold water tank 8 face downwards, making it convenient to clean the scale on the inner wall of the wastewater tank 7 and cold water tank 8. The cleaned scale can fall directly from the wastewater tank 7 or cold water tank 8, which is convenient and quick.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
