DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0042] Please refer to Figures 1-8 In the embodiments of the utility model, a waste heat recovery system for air compressor heat storage and anti-shutdown is provided, which comprises a compressor unit 1, a pressure stabilizing structure 2 and a waste heat recovery structure 3. The compressor unit 1 comprises a cylinder main body 106, and the cylinder main body 106 is internally provided with a No. 2 oil groove 107. A plurality of No. 1 fins 108 are fixedly installed in the No. 2 oil groove 107 at equal angles. The side surface of the No. 2 oil groove 107 is connected to a No. 1 oil groove 104 through a pipeline, and the No. 1 oil groove 104 is arranged in the vortex compressor shell 102. The pressure stabilizing structure 2 is fixedly installed on the front side surface of the compressor unit 1, and is connected to the No. 2 oil groove 107 through a pipeline. The waste heat recovery structure 3 is fixedly installed on the lower edge of the front side of the compressor unit 1, and is connected to the pressure stabilizing structure 2 and the No. 1 oil groove 104.

[0043] Specifically, the first heat sink 108 is designed to be optimized in the space of the second oil groove 107 formed in the inner wall of the cylinder wall of the cylinder body 106. The first heat sink 108 itself provides a support and reinforcement effect, and uses transformer oil as a heat dissipation medium to fill the second oil groove 107 and completely wrap the second oil groove 107, thereby achieving heat absorption inside the cylinder wall. Meanwhile, the first oil groove 104 is formed in the shell wall of the vortex compressor shell 102 and is in communication with the second oil groove 107 and the pressure stabilizing structure 2 and the waste heat recovery structure 3, thereby forming an oil circulation flow channel that completely covers two positions of compressed air to absorb heat from the inside of the shell, improve the heat dissipation speed, reduce heat loss, improve heat absorption rate, and further improve the heat recovery effect.

[0044] Embodiment One

[0045] As shown in Figures 2-5 In this embodiment, the compressor set 1 further includes a main shell 101, a vortex compressor mounting groove 103, a cylinder base 105, and a cylinder cover 109. The main shell 101 is fixedly connected to the vortex compressor shell 102 on one side. The vortex compressor mounting groove 103 is formed in the inner wall of the vortex compressor shell 102, and the first oil groove 104 is formed in the side wall of the vortex compressor mounting groove 103. The cylinder base 105 is fixedly installed on the upper surface of the main shell 101, and the cylinder body 106 is fixedly installed on the upper surface of the cylinder base 105. The cylinder cover 109 is fixedly installed on the upper surface of the cylinder body 106.

[0046] In this embodiment, the piston rod of the stamping type compressed air is slidably inserted into the cylinder base 105 and the cylinder body 106. The internal structure of the vortex compressor is installed in the vortex compressor mounting groove 103. The vortex compressor mounting groove 103 and the cylinder cover 109 are connected by a pipeline. Air is first preliminarily compressed by the vortex compressor and then finally stored in the air tank by the cylinder. Different mechanisms are used to compress air in stages to improve the compression effect. The heat dissipation and heat absorption sites are also divided into two stages to avoid the instantaneous temperature being too high when single-stage compressed air is generated, which cannot be cooled in time, resulting in equipment overload shutdown.

[0047] As shown in Figures 6-7As shown, in this embodiment, the pressure stabilizing structure 2 includes a pressure stabilizing tank 201, a piston plate 202, a spring base 203, a connecting rod 204, an adjusting screw 205, a spring pressure plate 206, a return spring 207, and a hexagonal nut 208. The rear edge of the upper surface of the pressure stabilizing tank 201 is connected to the bottom side of the No. 2 oil tank 107 via a pipe. The piston plate 202 is slidably engaged inside the pressure stabilizing tank 201. The spring base 203 is fixedly installed on the upper surface of the pressure stabilizing tank 201. The connecting rod 204 passes through the spring base 203 and is fixedly connected to the piston plate 202. The adjusting screw 205 is screwed onto the upper end of the connecting rod 204. The spring pressure plate 206 is fixedly installed on the upper end of the adjusting screw 205. The return spring 207 is engaged between the spring pressure plate 206 and the spring base 203. The hexagonal nut 208 is fixedly installed on the upper surface of the spring pressure plate 206.

[0048] In practice, after the transformer oil dissipates heat in the waste heat recovery structure 3, it is pumped by oil pump 209 through the upper space of piston plate 202 inside pressure stabilizing tank 201 and filled into oil tank 107. The return spring 207 abuts against spring pressure plate 206, and through adjusting screw 205 and connecting rod 204, it transmits an upward elastic pulling force to piston plate 202 to balance the oil pressure changes caused by temperature changes, equipment shutdowns, etc., and ensure the stability of the oil delivery system. When necessary, the adjustment screw 205 can be turned by hexagonal nut 208 to adjust the pressure of spring pressure plate 206 on return spring 207, thereby adjusting the amount of elastic potential energy accumulated in return spring 207, and adjusting the balancing effect of piston plate 202 within a certain range.

The number of second heat sinks 302 is several, and the several second heat sinks 302 are arranged at equal intervals and fixedly installed inside the insulation box 301. The heat exchange tube coil 303 is inserted into the middle of the second heat sink 302. One end of the heat exchange tube coil 303 is connected to the pressure stabilizing tank 201, and the other end of the heat exchange tube coil 303 is connected to the first oil tank 104. A water inlet 304 is fixedly installed on one edge of the upper surface of the insulation box 301, and a water outlet 305 is fixedly installed on the other edge of the lower surface of the insulation box 301.

[0052] In the embodiment, the oil liquid first absorbs heat in the second oil tank 107, then absorbs heat from the first oil tank 104, and finally flows into the heat exchange pipe disc 303 to be cooled through the second radiating fins 302 and the high-temperature hot oil in the heat exchange pipe disc 303.
