[0002] In many industrial enterprises, air compressors are essential equipment to ensure normal production. Since air compressors generate a lot of waste heat during operation, in order to reduce energy waste, air compressors are usually equipped with waste heat recovery machines to recycle the heat they generate. By absorbing the waste heat of the air compressor to heat the cold water, it can solve the problems of employee life and industrial hot water.

[0003] During the use of the existing air compressor waste heat recovery machine, in order to ensure the waste heat recovery effect, the staff needs to regularly inspect the body. During the inspection, the staff needs to use a screwdriver to loosen multiple sets of screws on the two side panels in turn to remove the two side panels. After the inspection is completed, the screwing steps need to be repeated to reinstall the two side panels. The whole operation process is cumbersome and laborious. For this reason, we propose an air compressor heat recovery device to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , an air compressor heat recovery device, including an air compressor waste heat recovery machine 1, the interior of the air compressor waste heat recovery machine 1 is covered with a baffle 2, and the side of the baffle 2 is evenly distributed with heat dissipation holes 3. The working principle of the air compressor waste heat recovery machine 1 is the existing technology, which will not be repeated here. By opening the heat dissipation holes 3, the normal heat dissipation of the air compressor waste heat recovery machine 1 can be ensured. Since the baffle 2 is set to be U-shaped, when the baffle 2 is lifted, the internal parts of the air compressor waste heat recovery machine 1 can be exposed, so that the staff can perform maintenance operations. The top of the baffle 2 is connected to a connecting plate 4, and the connection The bottom end of the plate 4 is connected to a toothed plate 7, the inner wall of the air compressor waste heat recovery machine 1 is provided with a receiving groove 5, and the top of the receiving groove 5 is connected to a gear 6 through a bearing, the front of the gear 6 is connected to a rotating shaft 8, and the front end of the rotating shaft 8 extends to the outside of the air compressor waste heat recovery machine 1 and is connected to a rotating block 9, a limit block 10 is inserted into the rotating block 9, and the outer wall of the air compressor waste heat recovery machine 1 is provided with limit grooves that are compatible with the limit blocks 10 at equal intervals, and the limit grooves are distributed in a ring array structure, and the rotating shaft 8 rotated to a suitable position can be limited by the mutual cooperation of the limit blocks 10 and the limit grooves.

[0023] Further, see Figure 2 and Figure 3 It can be known that the inner wall of the air compressor waste heat recovery machine 1 is symmetrically connected with a fixing plate 12, and the inside of the fixing plate 12 is provided with grooves, and a guide rod 13 is inserted into the groove, and the top of the guide rod 13 is fixedly connected to the baffle 2. When in use, the guide rod 13 connected to the baffle 2 and the opening of the groove can ensure the stability of the baffle 2 during the up and down lifting process.

[0024] Further, see Figure 3 It can be known that the bottom end of the guide rod 13 is sleeved with a sleeve rod 14, and the bottom end of the sleeve rod 14 is set to rubber material, and the diameter of the sleeve rod 14 is larger than the slot. When in use, through the setting of the sleeve rod 14 and because the sleeve rod 14 is set to rubber material, the bottom end of the guide rod 13 can be prevented from directly colliding with the inner wall of the air compressor waste heat recovery machine 1, so as to realize the protection operation of the air compressor waste heat recovery machine 1 and the guide rod 13. Since the diameter of the sleeve rod 14 is larger than the slot, the upward baffle 2 can be limited.

[0025] Further, see Figure 3It can be known that the inner wall of the sleeve rod 14 is provided with an internal thread, and the bottom end of the guide rod 13 is provided with an external thread matched with the sleeve rod 14. Through the threaded connection between the sleeve rod 14 and the guide rod 13, the four groups of sleeve rods 14 can be easily removed from the bottom ends of the four groups of guide rods 13 in turn, so that the staff can easily take out the baffle 2 that has reached the end of its service life from the upper room of the air compressor waste heat recovery machine 1 for replacement.

[0026] Further, see Figure 4 It can be known that the limit block 10 is set as a U-shaped structure, the inner wall of the limit groove and the outer wall of the limit block 10 are tightly fitted, and the limit block 10 set by the U-shaped structure and the mortise and tenon connection between the limit block 10 and the limit groove can effectively ensure the limiting effect of the device on the rotating shaft 8.

[0027] Further, see Figure 2 and Figure 3 It can be known that support rods 15 are symmetrically distributed on the front and rear sides of the air compressor waste heat recovery machine 1, and a brush 11 is connected to the side of the support rod 15 that is away from each other. When the baffle 2 is pulled up, the brush 11 can be inserted into the heat dissipation hole 3, so that the dust and debris inside the heat dissipation hole 3 can be scraped off. There is no need for staff to manually perform cleaning operations, which can effectively improve the convenience of the device during use.

[0028] Further, see Figure 3 It can be known that the support rod 15 is set to a U-shaped structure, and the left and right sides of the support rod 15 are connected to the inner wall of the air compressor waste heat recovery machine 1 by bolts. After the brush 11 reaches the end of its service life, the staff can first remove the baffle 2 and the guide rod 13 from the inside of the air compressor waste heat recovery machine 1, and then use tools to remove the U-shaped support rod 15 from the inner wall of the air compressor waste heat recovery machine 1 to achieve the replacement of the brush 11, thereby effectively ensuring its cleaning effect on the inside of the heat dissipation hole 3.

[0029] Working principle: When the utility model is in use, the staff can first connect the device to the air compressor to realize the recovery and utilization of the waste heat generated by the air compressor. After using it for a period of time, the staff can first pull the limit block 10 to pull it out from the limit groove inside the rotating block 9 and the air compressor waste heat recovery machine 1, and then the staff can manually rotate the rotating block 9, thereby driving the rotating shaft 8 and the gear 6 to rotate at the same time. Since the gear 6 and the toothed plate 7 are meshed, when the gear 6 rotates, the toothed plate 7 can be forced to slide inside the accommodating groove 5, and drive the connecting plate 4 and the baffle 2 to lift up as a whole. When the sleeve rod 14 and the fixed plate 12 are in contact, the baffle 2 is limited by the sleeve rod 14 and cannot be lifted up. At this time, the staff can insert the limit block 10 into the inside of the rotating block 9, and push the limit block 10 again to insert it into the corresponding limit groove opened inside the air compressor waste heat recovery machine 1 to achieve the limit of the rotating block 9 and the rotating shaft 8, so that the baffle 2 can be kept in the lifted state, and it is convenient for the staff to repair the parts inside the air compressor waste heat recovery machine 1. After the maintenance is completed, the staff can pull the limit block 10 out of the inside of the rotating block 9 again to contact the limit of the gear 6. At this time, the baffle 2 can fall under gravity and re-cover and surround the air compressor waste heat recovery machine 1, and then the staff can use the limit block 10 to limit the rotating block 9. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
