[0032] The following is combined with Figure 1-5 The present invention is described in further detail.

[0033] The invention discloses a rapid cooling device for processing heavy truck wheel hub nuts, comprising a box body 1 and a feed hopper 2 arranged on the box body 1. The inner cavity of the box body 1 is provided with a dividing mechanism 3, a guide plate 4, a collecting hopper 5 and a cold water tank 6 in sequence from top to bottom. After a batch of heavy truck wheel hub nuts enter the box body 1 from the feed hopper 2, they are rapidly cooled by passing through the dividing mechanism 3, the guide plate 4 and the collecting hopper 5 in sequence. The cold water tank 6 provides a cold source for rapid cooling, and the cooled water is recycled through the cold water tank 6, so as to save water.

[0034] The guide plate 4 is tilted so that the wheel hub nuts that fall onto the guide plate 4 can slowly move downward. The collecting hopper 5 is detachably connected to the bottom of the guide plate 4. The nuts that move downward from the guide plate 4 will be collected by the collecting hopper 5, which is convenient for taking out the nuts after rapid cooling. The outer wall of the guide plate 4 and the bottom of the collecting hopper 5 are both provided with leakage holes 41. The setting of the leakage holes 41 can expose the water source on the nuts after rapid cooling, thereby realizing the recycling of the water source.

[0035] The material distribution mechanism 3 includes a vibrating material distribution cover 31 arranged just below the feed hopper 2, and both sides of the vibrating material distribution cover 31 are connected with the material turning plate 32 through the crankshaft 312. The nuts dropped from the feed hopper 2 will be divided to both sides after passing through the vibrating material distribution cover 31, and fall on the material turning plates 32 on both sides, and at the same time, the material turning plates 32 will be driven to rotate. During the rotation process, the vibrating material distribution cover 31 is driven by the crankshaft 312 to vibrate up and down, so that the nuts can be quickly distributed to avoid blockage and accumulation. A cold water pump 7 is installed on the side wall of the box body 1. The input end of the cold water pump 7 is connected to the cold water tank 6 through the driving mechanism 10, and the output end of the cold water pump 7 is connected to the spray pipe 8 installed above the guide plate 4. Under the action of the cold water pump 7, the nuts located in the cold water tank 6 The water source inside works through the driving mechanism 10, and at the same time, the water flow is pumped into the spray pipe 8, and the nuts on the guide plate 4 are quickly cooled through the spray pipe 8. An air suction mechanism 9 and a heat exchanger 11 are installed in the air suction chamber 901 on one side of the box body 1, and a negative pressure port 905 is provided between the air suction chamber 901 and the box body 1. The heat exchanger 11 is connected to the cold water tank 6 through a return pipe 12. Under the action of the air suction mechanism 9, the high-temperature water vapor generated above the guide plate 4 is sucked in through the negative pressure port 905, and then blown onto the heat exchanger 11. After heat exchange in the heat exchanger 11, the heat of the high-temperature steam can be utilized, and the condensed water source can be returned to the cold water tank 6 through the return pipe 12 for utilization, thereby effectively reducing the loss of water source.

[0036] Reference Figure 2The driving mechanism 10 includes a shroud 101, one side of which is connected to the cold water tank 6, and the other side of the shroud 101 is connected to the input end of the cold water pump 7 through a pipeline. A driving blade 102 is installed inside the shroud 101, and the driving shaft 103 extending from the outside of the shroud 101 is connected to the suction mechanism 9. Under the action of the cold water pump 7, water will flow through the shroud 101, thereby driving the driving blade 102 to rotate, and the rotation of the driving blade 102 will drive the suction mechanism 9 to perform air extraction through the driving shaft 103.

[0037] Reference Figure 3 The suction mechanism 9 includes a suction chamber 901, a negative pressure port 905 is provided on the suction chamber 901, a mounting frame 902 is horizontally installed inside the suction chamber 901, a suction blade 903 is installed on the mounting frame 902, and the shaft of the suction blade 903 is connected to the driving mechanism 10 through a transmission shaft 904. The rotation of the driving mechanism 10 is transmitted to the suction blade 903 through the transmission shaft 904, driving the suction blade 903 to pump air, thereby extracting the high-temperature steam located on one side of the negative pressure port 905 to prevent the loss of high-temperature steam. A steam chamber is provided between the material distribution mechanism 3 and the guide plate 4, and the negative pressure port 905 is located on one side of the steam chamber. Under the action of the negative pressure port 905, the high-temperature steam in the steam chamber can be extracted.

[0038] Reference Figure 4 The vibrating material distributing cover 31 includes a transmission box 311 fixed in the box body 1, a crankshaft 312 is laterally inserted into the inner cavity of the transmission box 311, a guide column 313 is inserted on the top of the transmission box 311, a connecting rod 314 is connected between the cam of the crankshaft 312 and the guide column 313, a material distributing cover 315 is provided on the top of the guide column 313, and a spring 316 is provided between the transmission box 311 and the material distributing cover 315. When the crankshaft 312 rotates, the material distributing cover 315 connected to the top of the guide column 313 will be driven to move up and down through the connecting rod 314, and can be reset under the action of the spring 316.

[0039] Reference Figure 5 The turning plate 32 includes a sleeve 321, both ends of the crankshaft 312 are inserted into the sleeve 321, and the outer wall of the sleeve 321 is provided with multiple turning plate bodies 322 at equal intervals. The multiple turning plate bodies 322 can intermittently turn the fallen nuts to the guide plate 4 below, effectively avoiding the problem of incomplete cooling and accumulation of the nuts due to all of them accumulating on the guide plate 4. The turning plate body 322 is provided with ribs 323 on both sides, which can effectively avoid the nuts that fall on the turning plate body 322 from scattering.

[0040] The working principle of the rapid cooling device for machining a heavy truck hub nut of the present invention is as follows:

[0041] When in use, the processed high-temperature heavy-duty truck wheel hub nuts are poured into the box body 1 in batches from the feed hopper 2, and then pass through the dividing mechanism 3, the guide plate 4 and the collecting hopper 5 for rapid cooling in sequence. Among them, when passing through the dividing mechanism 3, the nuts will first fall on the dividing cover 31, and then be divided into the turning plates 32 on both sides. Under the action of the weight of the nuts, the return plates 32 will be driven to rotate, thereby driving the vibrating dividing cover 31 to vibrate up and down, and the nuts will be quickly divided to avoid blockage and accumulation. Then the nuts after division will fall onto the guide plate 4. At the same time, the cold water pump 7 works to spray the water in the cold water tank 6 through the spray pipe 8, so as to quickly cool the high-temperature nuts. A large amount of high-temperature steam will affect the cooling effect. At this time, under the action of water flow, the driving mechanism 10 drives the suction mechanism 9 to work. Under the action of the suction mechanism 9, the high-temperature water vapor generated above the guide plate 4 is sucked in through the negative pressure port 905, and then blown to the heat exchanger 11. After heat exchange in the heat exchanger 11, the heat of the high-temperature steam can be utilized, and the condensed water source can be returned to the cold water tank 6 through the reflux pipe 12 for utilization, effectively reducing the loss of water source; the nuts after rapid cooling finally move down along the guide plate 4 to the collecting hopper 5, and the cold water sprayed on the guide plate 4 and the water source flowing into the collecting hopper 5 will leak into the cold water tank 6 below, effectively avoiding the waste of water source.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
