Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The present invention provides a cooling furnace for cooling a pump body and a rotor after shrinkage jacketing. Figure 1 The overall structural schematic diagram of the cooling furnace in the embodiment of the present invention is shown, which includes a conveying system 10 and a cooling device 20 arranged above the conveying system 10 through a frame, wherein the cooling device 20 is used to cool the assembly conveyed by the conveying system 10, and the assembly is a pump body and a rotor after shrinkage; Figure 2 A schematic diagram of the bottom structure of a cooling device in an embodiment of the present invention is shown, wherein the cooling device 20 comprises a first air conditioner 21 and a second air conditioner 22 arranged in parallel, an air outlet of the first air conditioner 21 and an air outlet of the second air conditioner 22 are far away from each other, and the air outlet of the first air conditioner 21 and the air outlet of the second air conditioner 22 are connected by a plurality of cooling air ducts 30, and a plurality of the cooling air ducts 30 are located below the first air conditioner 21 and the second air conditioner 22; a plurality of the cooling air ducts 30 are divided into a top cooling air duct 31 and a transition air duct 32, the top cooling air duct 31 and the transition air duct 32 are parallel to each other, and a plurality of side cooling air ducts 33 are connected below any of the transition air ducts 32, and a plurality of the side cooling air ducts 33 and the top cooling air duct 31 are perpendicular to each other, the top cooling air duct 31 is used to output cold air to cool the top of the assembly, and a plurality of the side cooling air ducts 33 are used to output cold air to cool the side of the assembly; Figure 3 The schematic diagram of the structure of the cooling furnace without the first air conditioner and the second air conditioner in the embodiment of the present invention is shown, and a partition plate 40 is arranged below the first air conditioner 21 and the second air conditioner 22, and the partition plate 40 is located above the plurality of cooling air ducts 30; Figure 4 A side view structural schematic diagram of the cooling device in an embodiment of the present invention is shown, wherein the first air conditioner 21 is connected to a first air inlet duct 51 on a side close to the second air conditioner 22, and the second air conditioner 22 is connected to a second air inlet duct 52 on a side close to the first air conditioner 21, and the air inlet of the first air inlet duct 51 and the air inlet of the second air inlet duct 52 are both connected to the partition 40, and the first air inlet duct 51 and the second air inlet duct 52 are used to recover the air under the partition 40.

[0051] In the cooling furnace of the present invention, the air outlet of the first air conditioner 21 and the air outlet of the second air conditioner 22 are connected through the cooling air duct 30, so the two air conditioners can provide strong and sufficient cold air for the top cooling air duct 31 and the side cooling air duct 33, so as to surround the top and sides of the assembly for sufficient and rapid cooling; a large amount of cold air is scattered in the space below the partition 40, which contains relatively large amount of cold energy. The first air conditioner 21 is connected to the space below the partition 40 through the first air inlet duct 51, and the second air conditioner 22 is connected to the space below the partition 40 through the second air inlet duct 52, so the scattered cold air can be effectively recovered and recycled, so that the cold energy can be effectively utilized and the waste of cold energy can be reduced.

[0052] In addition, the first air conditioner 21 and the second air conditioner 22 are arranged in parallel, and the air outlets are far away from each other, the cooling air ducts 30 are parallel to each other, and the side cooling air ducts 33 and the top cooling air ducts 31 are perpendicular to each other; this can maintain a balanced pressure in various areas within the cooling air duct 30, thereby ensuring that the top cooling air duct 31 and the side cooling air duct 33 evenly output cold air, facilitating the formation of a balanced and stable cooling environment to cover the assemblies transported on the conveying system 10, avoiding overcooling or overheating in local areas, and ensuring that each assembly can be effectively cooled.

[0053] In some specific embodiments, see Figure 1 The space between the conveying system 10 and the cooling device 20 is a cooling space, and a plurality of baffles 60 are arranged around the cooling space. The baffles 60 surround most of the cooling space, which can effectively reduce the leakage of cold.

[0054] In some specific embodiments, see Figure 3 and 4 , the air inlet of the first air inlet duct 51 and the air inlet of the second air inlet duct 52 are both aligned with the geometric center area of ​​the cooling space. The geometric center area of ​​the cooling space has the most surplus cooling capacity. Aligning the air inlet of the first air inlet duct 51 and the air inlet of the second air inlet duct 52 with the geometric center area of ​​the cooling space can, on the one hand, efficiently recycle cooling capacity, and on the other hand, is conducive to improving the uniformity of cooling capacity distribution in the cooling space.

[0055] In some specific embodiments, see Figure 2 There is a first interval between the cooling air ducts 30, which serves as an air flow channel to facilitate the air inlet duct of the air conditioner to recover the scattered cold air; a top cooling air duct 31 is arranged between two adjacent transition air ducts 32 to ensure that the top of the assembly transported on the conveying system 10 can be fully cooled.

[0056] Specifically, a plurality of first strip air outlet windows are provided on the side of any one of the top cold air ducts 31 facing the conveying system 10, and the plurality of first strip air outlet windows are arranged at equal intervals along the length direction of the top cold air duct 31, so as to evenly output cold air to cool the top of the assembly; a plurality of second strip air outlet windows are provided on both sides of any one of the side cold air ducts 33, and the plurality of second strip air outlet windows are arranged at equal intervals along the length direction of the side cold air duct 33, so as to evenly output cold air to cool the sides of the assembly.

[0057] In some specific embodiments, see Figure 4A first water receiving pan 71 is disposed below the first air conditioner 21, and the first water receiving pan 71 is located above the partition 40; a second water receiving pan 72 is disposed below the second air conditioner 22, and the second water receiving pan 72 is located above the partition 40. The water receiving pan can effectively collect and discharge condensed water generated during the operation of the air conditioner to prevent the condensed water from dripping onto the conveying system 10.

[0058] Figure 5 The top view of the conveying system in the embodiment of the present invention is shown, wherein the conveying system 10 comprises a feeding conveying line 100, a material distribution conveying line 200, a material discharging conveying line 300, a plurality of cooling conveying lines 400 and a plurality of carrying trays 500, wherein the carrying trays 500 are used to carry a plurality of the assemblies, and the carrying trays 500 circulate on the feeding conveying line 100, the material distribution conveying line 200, the plurality of cooling conveying lines 400 and the material discharging conveying line 300 in sequence; The end of the feed conveyor line 100 is connected to the material distribution conveyor line 200, the head end of the feed conveyor line 100 is connected to the discharge conveyor line 300, and the distribution conveyor line 200 and the discharge conveyor line 300 are parallel to each other; the head ends of the multiple cooling conveyor lines 400 are connected to the material distribution conveyor line 200, the ends of the multiple cooling conveyor lines 400 are connected to the discharge conveyor line 300, and the feed conveyor line 100 and the multiple cooling conveyor lines 400 are parallel to each other.

[0059] In the conveying system 10 of the cooling furnace, the layout of the conveying lines is compact and occupies a small area; moreover, due to the special arrangement of each conveying line, the assembly on the carrier tray 500 will not change direction during the conveying process, so the cooled assembly can be put into the next assembly process without correction.

[0060] For details, please refer to Figure 5 The feed conveyor line 100 is provided with a loading station 110, and the carrying tray 500 receives the assembly in the loading station 110; the end of the feed conveyor line 100 is used to convey the carrying tray 500 to the material distribution conveyor line 200, and the head end of the feed conveyor line 100 is used to receive the carrying tray 500 conveyed by the discharging conveyor line 300; Figure 6 The corresponding structural schematic diagram of the cooling air duct, the side cooling air duct and the conveying system in the embodiment of the present invention is shown. The feed conveying line 100 is located outside the direct cooling range of the cooling device 20, that is, the assembly on the feed conveying line 100 will not be directly blown by the cold air output by the cooling device 20. On the one hand, this can prevent the cooling device 20 from hindering the feeding of the feed conveying line 100; on the other hand, since there will not be too many assemblies on the feed conveying line 100 and the assemblies will not stay on the feed conveying line 100 for too long, they can be set outside the direct cooling range of the cooling device 20.

The assembly is mainly cooled on the cooling conveyor line 400.

[0063] For details, please refer to Figure 5 The unloading conveyor line 300 is provided with a discharge station 310 at one end close to the feeding conveyor line 100, and the carrying tray 500 is unloaded from the assembly at the discharge station 310; the end of the unloading conveyor line 300 is used to transport the carrying tray 500 to the feeding conveyor line 100; please refer to Figure 6 , the discharging conveyor line 300 is cooled by the corresponding top cooling air duct 31. The top of the unloading station 310 and the top of the end of the discharging conveyor line 300 are not covered by the top cooling air duct 31; when the unloading station 310 unloads, the assembly does not need to correct the direction.

The output end of the first intercepting cylinder 131 is vertically upwardly arranged, and the first intercepting block 132 is fixedly arranged on the output end of the first intercepting cylinder 131. The first pneumatic intercepting mechanism 130 is sensitive in response and can quickly intercept or release the carrying tray 500.

[0070] When the first lifting transfer mechanism 220 of the main body of the material distribution conveyor line 200 is in operation, the second pneumatic intercepting mechanism 228 first stops the carrying pallet 500 on the second conveyor belt 210 above the corresponding first lifting transfer mechanism 220; then, the first lifting mechanism drives the first transfer mechanism to rise to contact with the carrying pallet 500, and pushes the carrying pallet 500 away from the second conveyor belt 210, wherein the first limiting rail 225 limits the carrying pallet 500 between the two first sub-rails to prevent the carrying pallet 500 from running off the track; then, the first active conveying roller 226 actively pushes the carrying pallet 500 out of the first transfer mechanism, that is, pushes the carrying pallet 500 out of the material distribution conveyor line 200; finally, the first lifting mechanism drives the first transfer mechanism to lower its height to return to its original position, and the second pneumatic intercepting mechanism 228 is reset.
