Description

Technical Field

[0001] The utility model relates to the technical field of water temperature regulation, in particular to a heat exchanger for seawater aquaculture. Background Art

[0002] Seawater aquaculture is a production activity that utilizes the shallow coastal beaches to breed marine aquatic economic animals and plants. During seawater aquaculture, since some fry have relatively high temperature requirements for juvenile breeding, a heat exchanger is often used to heat the seawater in the seawater area for fry breeding.

[0003] Common heat exchangers generally use heat exchange tubes to exchange heat between the heat flow and the cold flow. The heat flow generally flows through the surface of the heat exchange tubes. After long-term use of the heat exchanger, moss and other sundries are likely to grow on the surface of the heat exchange tubes, and it is necessary to clean them to avoid affecting the heat exchange efficiency. However, for common heat exchangers, when removing the heat exchange components for cleaning, it is necessary to disassemble many connecting components such as bolts, and it is time-consuming to position the heat exchange components after resetting. Therefore, a heat exchanger for seawater aquaculture is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat exchanger for seawater aquaculture to solve the problems raised in the above background art: after long-term use of the heat exchanger, moss and other sundries are likely to grow on the surface of the heat exchange tubes, and it is necessary to clean them to avoid affecting the heat exchange efficiency. However, for common heat exchangers, when removing the heat exchange components for cleaning, it is necessary to disassemble many connecting components such as bolts, and it is time-consuming to position the heat exchange components after resetting.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A heat exchanger for seawater aquaculture, including a protective housing. One end of the protective housing is flange-connected with a cold flow filling component, and the other end of the protective housing is flange-connected with a sealing cover plate. An exchange heat passage is arranged inside the protective housing, and a heat exchange component is inserted between the inner walls of the protective housing. On one side of the upper surface of the protective housing near the sealing cover plate, there is a heat flow inlet pipe, and on one side of the lower surface of the protective housing near the cold flow filling component, there is a heat flow outlet pipe. A waterproof microswitch is installed at the top of the inner wall of the protective housing near the cold flow filling component, and fixed legs are installed on both sides of the lower surface of the protective housing. Two electric telescopic rods are installed on the outside of the protective housing near the cold flow filling component, and the telescopic ends of the two electric telescopic rods are fixedly connected with positioning pin rods. A light sensor switch is installed on the protective housing near the sealing cover plate, and the detection end of the light sensor switch is directly opposite to the position of the sealing cover plate. The purpose of such a setting is: When it is necessary to clean the heat exchange component, first separate the sealing cover plate. When the light sensor switch detects light, control the electric telescopic rod to contract so that the positioning pin rod is separated from the positioning pin hole. Then take out the U-shaped heat exchange tube and the installation disc to clean the impurities and moss on their surfaces. Then reset the U-shaped heat exchange tube and the installation disc. When the installation disc contacts the waterproof microswitch, the electric telescopic rod extends so that the positioning pin rod is inserted into the positioning pin hole, saving the time for installing the heat exchange component.

[0006] Preferably, the cold flow filling component includes a cold flow housing, and a cold flow inlet pipe is arranged on the upper surface of the cold flow housing.

[0007] Preferably, a cold flow outlet pipe is arranged on the lower surface of the cold flow housing, and a flow dividing partition is fixedly connected to the center of the inner wall of the cold flow housing.

[0010] Preferably, the two positioning pin rods are inserted into the positioning pin holes that are in the correct position.

[0011] The technical effects and advantages of the present utility model:

[0012] (1) When the heat exchange component of this device needs to be cleaned, first separate the sealing cover plate. When the light sensor switch detects light, control the electric telescopic rod to contract, so that the positioning pin rod is separated from the positioning pin hole. Then take out the U-shaped heat exchange tube and the mounting disc to clean the impurities and moss on their surfaces. Then reset the U-shaped heat exchange tube and the mounting disc. When the mounting disc contacts the waterproof microswitch, the electric telescopic rod extends to make the positioning pin rod inserted into the positioning pin hole, saving the time for installing the heat exchange component, solving the problem that moss and other sundries are likely to grow on the surface of the heat exchange tube after the heat exchanger is used for a long time and need to be cleaned to avoid affecting the heat exchange efficiency. For common heat exchangers, removing and cleaning the heat exchange component requires disassembling many connecting components such as bolts, and positioning is time-consuming after resetting the heat exchange component.

[0013] (2) This device conducts heat exchange on seawater through the cold flow injection component, heat exchange component, hot flow inlet pipe and hot flow outlet pipe. The seawater to be heated is injected into the cold flow jacket through the cold flow inlet pipe.
