Technical Field
[0001] This utility model relates to the field of air compressor technology, specifically to an energy-saving device for waste heat recovery and utilization of air compressors. Background Technology
[0002] An air compressor is a device used to compress gas. Similar in structure to a water pump, an air compressor generates a large amount of heat energy when it is working. This heat energy is usually recovered and reused by connecting a heat exchanger through pipes.
[0003] Existing waste heat recovery and energy-saving devices for air compressors do not have automatic temperature control during use. They can only passively exchange heat with water for waste heat recovery. After heat exchange, the water is still at a high temperature and cannot achieve automatic rapid cooling, thus reducing the waste heat recovery effect. Therefore, it is necessary to design a waste heat recovery and energy-saving device with automatic temperature control function. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving device for waste heat recovery and utilization of air compressors, comprising a water tank, an inlet pipe connected to the top of the water tank, an outlet pipe connected to the bottom of the water tank, electromagnetic flow valves fixedly connected to the inner cavities of both the inlet and outlet pipes, a heat exchange tube fixedly connected to the inner cavity of the water tank, both ends of the heat exchange tube extending to the outside of the water tank, and temperature sensors fixedly connected to the front and rear ends of the bottom sides of the inner cavity of the water tank.
[0006] A stirring rod is fixedly connected to the back of the inner cavity of the water tank and at the gap of the heat exchange tube via a bearing. The other end of the stirring rod extends to the outside of the water tank and is fixedly connected to a transmission gear. The upper and lower transmission gears mesh with each other. A driven bevel gear is fixedly connected to the surface of the top transmission gear. A driving bevel gear meshes with the surface of the driven bevel gear. A transmission shaft is fixedly connected between the three driving bevel gears. A protective cover is fixedly connected to one end of the transmission shaft via a bearing. The back of the protective cover is fixedly connected to the surface of the water tank. The other end of the transmission shaft extends to the outside of the protective cover and is fixedly connected to a drive motor.
[0007] Preferably, the water tank is fixedly connected to four corners at the bottom, and the bottom of the support legs is provided with anti-slip texture.
[0008] Preferably, both sides of the bottom of the water tank cavity are fixedly connected to guide plates, and the guide plates are symmetrically inclined.
[0009] Preferably, the surface of the water tank has a circular hole through which the heat exchange tube passes, and a sealing ring is fitted between the circular hole and the heat exchange tube.
[0010] Preferably, the heat exchange tube has external threads on both ends of its surface outside the water tank, and the external threads on its surface are threadedly connected to the internal threads of the external connecting pipe.
[0011] Preferably, the bottom of the drive motor is fixedly connected to a mounting base, and one side of the mounting base is fixedly connected to the surface of the protective cover.
[0012] Preferably, a controller is fixedly connected to the surface of the protective cover, and the controller is electrically connected to the electrical equipment via wires.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a temperature sensor to monitor the temperature of the water inside the water tank. In the event of high temperatures, the electromagnetic flow valves in the inlet and outlet pipes are opened to their maximum, allowing the water in the tank to flow rapidly and carry away a large amount of heat, achieving efficient heat dissipation. At the same time, the transmission component drives multiple stirring rods to rotate, which mixes the water in the tank evenly, preventing localized high temperatures after heat exchange with the heat exchange tubes. This ensures uniform heating and achieves good heat exchange effect, bringing great convenience to daily use.
[0015] 2. This utility model ensures the stability of the equipment by setting support legs, achieves the function of guiding water flow by setting guide plates, and can quickly discharge water by setting mounting bases. It also ensures the stability of the drive motor by setting controllers, and realizes the automatic control of the equipment by setting controllers. Attached Figure Description
