Technical Field
[0001] This utility model belongs to the field of air compressor heat energy recovery technology, specifically relating to an air compressor heat energy recovery and reuse device. Background Technology
[0002] An air compressor, also known as an air compressor, is a device that converts the mechanical energy of a prime mover into the pressure energy of gas. It is a device that generates compressed air pressure. Compressed air can be used as a power source to drive various pneumatic machinery. In addition, it can also be used to control instruments and automation devices. It is widely used in various industrial scenarios.
[0003] Air compressors, which are widely used in industrial settings, generate a lot of heat energy during the air compression process. A large amount of input electrical energy is lost as heat. This heat energy is often directly discharged into the environment through air-cooling or water-cooling systems and is not effectively utilized, which not only wastes energy but also increases the environmental heat load. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a heat recovery and reuse device for air compressors, which solves the problem that air compressors, which are widely used in industrial settings, generate a large amount of heat energy during the air compression process. A large amount of input electrical energy is lost in the form of heat. This heat energy is often directly discharged into the environment through air-cooling or water-cooling systems and is not effectively utilized, resulting in energy waste and increased environmental heat load.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air compressor heat energy recovery and reuse device, comprising a hot air chamber, an air supply pipe connected to the upper side of one side of the hot air chamber, an exhaust fan connected to the end of the air supply pipe away from the hot air chamber, circulating fans equidistantly arranged on the upper inner side of the hot air chamber, an upper-level mesh conveyor belt and a lower-level mesh conveyor belt horizontally arranged on the inner side of the hot air chamber, a material box connected to the side of the hot air chamber away from the air supply pipe, an inlet on the upper side of the material box, and an outlet on the lower side of the side of the material box away from the hot air chamber, the input side of the upper-level mesh conveyor belt being close to the inlet, a material drop gap existing between the output side of the upper-level mesh conveyor belt and the inner wall of the hot air chamber, the input side of the lower-level mesh conveyor belt being close to the inner wall of the hot air chamber, and the input side of the lower-level mesh conveyor belt being directly opposite the material drop gap between the upper-level mesh conveyor belt and the hot air chamber.
[0006] The beneficial effects of this utility model are as follows: When the circulating fan is started, the circulating fan can continuously blow the hot air blown into the hot air chamber downwards. The hot air flows downwards and can continuously pass through the upper and lower mesh conveyor belts to dry the materials conveyed on the upper and lower mesh conveyor belts. This can effectively reuse the large amount of heat generated by the air compressor and apply it to material drying, avoiding the direct discharge of this heat energy into the environment, thus avoiding energy waste and reducing the environmental heat load to a certain extent.

The feeding sloping plate is inclined downwards towards the upper-level mesh conveyor belt, and the lower side of the feeding sloping plate is close to the input side of the upper-level mesh conveyor belt. A discharge sloping plate is fixedly installed on the lower inner side of the material box, and the discharge sloping plate is inclined downwards towards the discharge outlet. The upper side of the discharge sloping plate is close to the lower output side of the lower-level mesh conveyor belt, and the lower side of the discharge sloping plate is close to the discharge outlet.

[0012] The beneficial effects of this improvement are as follows: when the exhaust fan is started, the input end of the exhaust fan draws air from the bottom of the hot air chamber through the air extraction pipe, and then discharges it to the outside through the exhaust pipe. The output end of the exhaust pipe is connected to the gas discharge pipe, which can continuously discharge the dried exhaust gas from the inside of the hot air chamber.
[0013] To improve the drying effect of the materials;
[0014] As a further improvement to the above technical solution: Material-pulling rods are arranged side-by-side on the inner side of the hot air chamber. These rods are positioned in the area between the circulating fans. Each material-pulling rod includes a shaft, a fixed rod, a deflecting plate, and a rubber strip. The shafts are rotatably connected to the hot air chamber. Fixed rods are symmetrically fixed to the outer sides of the shafts.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0036] like Figure 1 — Figure 5The device shown is a heat recovery and reuse device for an air compressor, including a hot air chamber 1. An air supply pipe 2 is connected to the upper side of one side of the hot air chamber 1. An exhaust fan 3 is connected to the end of the air supply pipe 2 away from the hot air chamber 1. Circulating fans 4 are equidistantly arranged on the upper inner side of the hot air chamber 1. An upper-level mesh conveyor belt 5 and a lower-level mesh conveyor belt 6 are horizontally arranged vertically on the inner side of the hot air chamber 1. A material box 7 is connected to the side of the hot air chamber 1 away from the air supply pipe 2. An inlet 8 is opened on the upper side of the material box 7, and an outlet 10 is opened on the lower side of the side of the material box 7 away from the hot air chamber 1. The input of the upper-level mesh conveyor belt 5... The upper mesh conveyor belt 5 has a material drop gap on its output side near the feed inlet 8 and on its inner wall near the hot air chamber 1. The lower mesh conveyor belt 6 has its input side near the inner wall of the hot air chamber 1 and is directly opposite the material drop gap between the upper mesh conveyor belt 5 and the hot air chamber 1. When the circulating fan 4 is started, it continuously blows hot air into the hot air chamber 1 downwards. This downward flow of hot air allows it to continuously pass through the upper mesh conveyor belt 5 and the lower mesh conveyor belt 6, drying the material conveyed on the upper side of the two conveyor belts. This process also reduces the heat generated by the air compressor. The heat generated can be effectively reused for material drying, avoiding direct emission of this heat energy into the environment, thus preventing energy waste and reducing the environmental heat load to some extent. A feeding ramp 9 is fixedly installed on the inner wall of the material box 7 away from the hot air chamber 1, near the feed inlet 8. The feeding ramp 9 is inclined downwards towards the upper-level mesh conveyor belt 5, with its lower side close to the input side of the upper-level mesh conveyor belt 5. A discharge ramp 11 is fixedly installed on the lower inner side of the material box 7, inclined downwards towards the discharge outlet 10, with its upper side close to the discharge outlet 10. Below the output side of the lower mesh conveyor belt 6, near the discharge port 10 on the lower side of the discharge ramp 11, and the feed ramp 9 below the feed port 8, are used to stably guide the material to the upper input side of the upper mesh conveyor belt 5 during feeding. The discharge ramp 11 at the bottom inner side of the material box 7 is used to stably discharge the material discharged from the lower mesh conveyor belt 6 from the discharge port 10. An exhaust pipe 12 is connected to the lower inner side of the hot air chamber 1 near the material box 7. An exhaust fan 13 is connected to the output end of the exhaust pipe 12. An exhaust pipe 14 is connected to the upper output end of the exhaust fan 13. When the exhaust fan 13 is started...The input end of the exhaust fan 13 draws air from the bottom of the inner side of the hot air chamber 1 through the extraction pipe 12, and then discharges it to the outside through the exhaust pipe 14. The output end of the exhaust pipe 14 is connected to the gas discharge pipe, which can continuously discharge the exhaust gas dried inside the hot air chamber 1. The inner side of the hot air chamber 1 is provided with material-pulling rods 15 arranged vertically. The material-pulling rods 15 are located in the area between the circulating fans 4. The material-pulling rods 15 include shafts 151, fixed rods 152, actuating plates 153 and rubber strips 154. The shafts 151 are all rotatably connected to the hot air chamber 1, and the outer sides of the shafts 151 are symmetrically fixed. A fixed rod 152 is fixedly provided. A deflector plate 153 is fixedly provided at the end of the fixed rod 152 away from the shaft 151. When the deflector plate 153 rotates, it is close to the upper side of the upper mesh conveyor belt 5 and the lower mesh conveyor belt 6 respectively. A motor 16 is fixedly provided on one side of the hot air chamber 1 corresponding to each deflector rod 15. The output ends of the motors 16 all penetrate into the inside of the hot air chamber 1 and are fixedly connected to the shaft 151. The output ends of the motors 16 drive the fixed rod 152 to rotate through the shaft 151. The fixed rod 152 drives the deflector plate 153 to repeatedly deflect the lower conveyor belt. The material can be turned over to a certain extent, increasing the drying effect. Rubber strips 154 are provided on the side of the agitator 153 away from the shaft 151. These rubber strips 154 are slidably engaged with the agitator 153. The rubber strips 154 increase the flexibility and cushioning effect, preventing damage to the material and the conveyor belt below during turning. Inside the hot air chamber 1, guide plates 17 are fixedly and alternately installed on the upper side of the input side of the lower mesh conveyor belt 6. Arc-shaped rubber strips 18 are fixedly installed side-by-side on the upper side of each guide plate 17. For some relatively fragile materials, [the following applies]. By setting up the guide ramp 17 and the arc-shaped rubber strip 18, the vertical height difference and speed of the material falling onto the upper side of the lower mesh conveyor belt 6 can be reduced, thus reducing the impact force of the falling material. Observation windows 19 are bolted to both sides of the hot air chamber 1 and the side away from the material box 7. The observation windows 19 facilitate observation of the material conveying and drying conditions inside the hot air chamber 1. Removing the observation windows 19 allows for regular maintenance of the equipment inside the hot air chamber 1. A buffer hopper 20 is fixedly connected to the upper side of the material box 7 corresponding to the feed inlet 8, serving as a buffer for the material being fed into the feed inlet 8.
[0037] Working principle and usage process of this utility model:
[0038] In use, the input end of the exhaust fan 3 can be connected to the heat dissipation port of the air compressor through a pipe, and then sent into the hot air chamber 1 through the air supply pipe 2. Material is continuously fed to the input side of the upper-level mesh conveyor belt 5 through the feed inlet 8 on the upper side of the material box 7. The material to be dried is slowly conveyed into the hot air chamber 1 through the upper-level mesh conveyor belt 5. Finally, the material falls from the drop gap on the output side of the upper-level mesh conveyor belt 5 onto the input side of the lower-level mesh conveyor belt 6. The lower-level mesh conveyor belt 6 slowly conveys the material, finally dropping it out from the output side. The feed ramp 9 below the feed inlet 8 is used to stably guide the material to the upper side of the input side of the upper-level mesh conveyor belt 5 during feeding. The discharge ramp is located at the bottom inside the material box 7. 11. Used to stably discharge the material discharged from the lower mesh conveyor belt 6 from the discharge port 10. During the material conveying process of the upper mesh conveyor belt 5 and the lower mesh conveyor belt 6, the circulating fan 4 is started. The circulating fan 4 can continuously blow the hot air blown into the hot air chamber 1 downward. The hot air flows downward and can continuously pass through the upper mesh conveyor belt 5 and the lower mesh conveyor belt 6 to dry the material conveyed on the upper side of the upper mesh conveyor belt 5 and the lower mesh conveyor belt 6. In this way, the large amount of heat generated by the air compressor can be effectively reused and applied to material drying, avoiding the direct discharge of this part of the heat energy into the environment, thereby avoiding energy waste and reducing the environmental heat load to a certain extent. In addition, the exhaust fan 13 is started. The input end of the exhaust fan 13 draws air from the bottom of the hot air chamber 1 through the suction pipe 12, and then discharges it through the exhaust pipe 14. The output end of the exhaust pipe 14 is connected to the gas discharge pipe, which can continuously discharge the waste gas dried inside the hot air chamber 1. In addition, a material-pulling rod 15 is set. The output end of the motor 16 drives the fixed rod 152 to rotate through the shaft 151. The fixed rod 152 drives the agitator plate 153 to repeatedly agitate the material conveyed below, which can turn the material to a certain extent and increase the drying effect of the material. In addition, a rubber... Strip 154 can increase the flexible buffering effect, which can, to a certain extent, prevent damage to materials and the conveyor belt below during turning. In addition, some materials are relatively fragile. By setting the guide plate 17 and the arc-shaped rubber strip 18, the vertical height difference and speed of the material falling onto the upper side of the lower mesh conveyor belt 6 can be reduced, thus reducing the impact force of falling material. In addition, the observation window plate 19 is set to facilitate the observation of the material conveying and drying status inside the hot air chamber 1. The observation window plate 19 can be removed for regular maintenance of the equipment inside the hot air chamber 1. In addition, the buffer hopper 20 is set for the feeding buffer at the feed inlet 8.
