[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types.

[0003] During operation, air compressors generate a large amount of heat, which is discharged to the outside of the machine along with the lubricating oil. This heat can reach temperatures as high as 100°C. Existing technologies typically use waste heat recovery devices to recover this heat. However, traditional waste heat recovery devices can usually only heat the water used to absorb heat to about 80°C, which has certain limitations. Therefore, there is an urgent need for a waste heat recovery and utilization device for air compressors. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-2 This utility model provides a technical solution: an air compressor waste heat recovery and utilization device, including a water tank 1 and an air compressor body 2. The air compressor body 2 is installed on one side of the water tank 1. Two partitions 3 are installed inside the water tank 1, and the two partitions 3 divide the inside of the water tank 1 into three heat exchange zones 4. A heat exchange component 5 for conveying oil inside the air compressor body 2 is installed between the three heat exchange zones 4. A temperature sensor 6 is installed in the lowest heat exchange zone 4. A drain pipe 7 is installed on each of the two partitions 3. A rotating shaft 8 is rotatably installed between the middle positions of the two partitions 3. Three sets of agitation components 9 are installed on the rotating shaft 8.

[0017] The heat exchange assembly 5 includes two central rotating disks 51 and four heat exchange tubes 52. The two central rotating disks 51 are respectively installed in the upper and lower heat exchange zones 4, and the four heat exchange tubes 52 are installed in a ring between the three heat exchange zones 4.

[0018] Two intermediate turntables 51 are respectively equipped with an inlet pipe 10 and an outlet pipe 11 on one side. One end of the inlet pipe 10 is connected to the air compressor body 2, and the other end of the outlet pipe 11 is connected to the pump body 12. The pump body 12 is connected to the air compressor body 2 through a connecting pipe.

[0019] A motor 13 is mounted on the upper part of the lower turntable 51, and the output shaft of the motor 13 is connected to the bottom end of the rotating shaft 8.

[0020] A liquid supply pipe 14 is installed on one side of the upper end of the water tank 1, and a drain pipe 15 is installed at the bottom of the water tank 1. Control valves are installed on the drain pipe 7 and the two drain pipes 15.

[0021] The agitation assembly 9 consists of several agitator plates, which are evenly fixed on the surface of the rotating shaft 8. Driven by the motor 13, the agitator plates can agitate the heat exchange liquid in each heat exchange zone 4 to ensure sufficient heat exchange.

[0022] Working Principle: The electronic equipment in this solution is connected to an external power supply and a main controller. During operation, the high-temperature liquid inside the air compressor body 2 is pumped into the intermediate plate 51 below the water tank 1 through the pump body 12 and the outlet pipe 11. Then, it moves upwards through four heat exchange tubes 52 into the upper intermediate plate 51. During this process, the highest-temperature oil just discharged from the air compressor body 2 first heats the heat exchange fluid in the lowest heat exchange zone 4. At this time, the lowest heat exchange fluid can continuously and fully exchange heat with the high-temperature oil, thereby heating the heat exchange fluid in this area to near the temperature just discharged from the air compressor body 2. This temperature is detected by the temperature sensor 6. When a certain level is reached, the oil is discharged by opening the control valve on drain pipe 2. After absorbing some heat in the lowest heat exchange zone 4, the oil flows through heat exchange pipe 52 and then through the middle heat exchange zone 4 and the upper heat exchange zone 4 to absorb the remaining heat in the oil and preheat the heat exchange fluid in the heat exchange zone 4. The preheated heat exchange fluid can be transported downwards through drain pipe 1 7 for heating. After drain pipe 2 sends out the heat exchange fluid in the lowest heat exchange zone 4, the heat exchange fluid in the middle heat exchange zone 4 enters the lowest heat exchange zone 4 through drain pipe 1 7 to replenish it. This process continues until the heat in the oil inside the air compressor body 2 is fully absorbed and the heat exchange fluid is heated to a certain level.
