Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for the production of PVC hoses. Background Technology

[0002] PVC hoses are transparent PVC hoses with smooth, uniform inner and outer walls free of air bubbles. Due to the high temperatures during production, PVC hoses are relatively soft and require cooling to solidify.

[0003] A search revealed that a utility model patent with patent authorization announcement number CN211416190U discloses a cooling device for PVC hose production, including a cooling pool and a base. The cooling pool is located on the upper side of the base, and a conduit is provided at the bottom of the cooling pool. The other end of the conduit is installed on a compression pump. The compression pump is connected to a heat exchanger through the conduit, and the heat exchanger is connected to an expansion valve through the conduit. The other end of the expansion valve is connected to the cooling pool through the conduit.

[0004] When the existing cooling device is in use, the cooling water in the cooling pool continuously exchanges heat with the PVC hose, causing the water temperature to gradually rise, which will affect the subsequent cooling efficiency and effect of the PVC hose. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for the production of PVC hoses, which solves the problem that in existing cooling devices, the cooling water in the cooling pool gradually rises in temperature due to continuous heat exchange with the PVC hoses, which affects the subsequent cooling efficiency and effect on the PVC hoses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for producing PVC hoses, comprising a cooling pool, a filter plate fixedly connected to the inner center of the cooling pool, two guide rollers installed on the upper end of the filter plate, multiple supports fixedly connected to the upper edge of the cooling pool, a top plate fixedly connected to the multiple supports, a hollow cylinder fixedly connected inside the top plate and penetrating the top plate, an auxiliary cooling mechanism provided inside the hollow cylinder, a circulating pump fixedly installed at the bottom of the inner side of the cooling pool, a conveying pipe fixedly connected to the output end of the circulating pump, the conveying pipe penetrating the cooling pool and extending above the cooling pool, the conveying pipe penetrating the top plate and slidably connected to the top plate, a diverter pipe fixedly connected to the end of the conveying pipe, and multiple nozzles provided at the bottom of the diverter pipe.

[0007] Preferably, a mesh made of stainless steel is fixedly connected to the inner side of the upper opening of the hollow cylinder. The mesh provides protection for the components inside the hollow cylinder.

[0008] Preferably, the auxiliary cooling mechanism includes multiple fixed rods fixedly connected to the inner wall of the hollow cylinder, and a connecting plate is fixedly connected to all the fixed rods. A motor is fixedly installed at the bottom of the connecting plate, and a rotating shaft is fixedly connected to the end of the output shaft of the motor. A bushing is slidably sleeved on the outer side of the rotating shaft, a stirring rod is fixedly connected to the lower outer side of the bushing, and a fan blade is fixedly connected to the middle outer side of the bushing. Through the setting of the auxiliary cooling mechanism, the cooling water in the cooling pool is cooled, keeping it at a relatively low temperature, thus ensuring the effectiveness and efficiency of cooling the PVC hose.

[0009] Preferably, a guide rod is fixedly connected inside the rotating shaft, and a guide block is fixedly connected to the inner wall of the bushing. The guide rod passes through the guide block and is slidably connected to it. The guide rod and guide block not only allow the bushing to rotate with the rotating shaft, but also provide guidance for the axial movement of the bushing along the rotating shaft.

[0010] Preferably, the guide block has balls on its side, and the balls contact the inner surface of the rotating shaft. The balls reduce the relative friction between the guide block and the rotating shaft.

[0011] Preferably, a linkage disc is fixedly connected to the upper outer side of the bushing, and two connecting balls are slidably connected to the side of the linkage disc. An electric push rod is fixedly installed at the bottom of the connecting plate, and the telescopic shaft of the electric push rod is fixedly connected to the connecting ball on the right side. By pushing the connecting ball on the right side with the electric push rod, the linkage disc is pushed, thereby causing the bushing to slide on the outside of the rotating shaft.

[0012] Preferably, a balance bar is fixedly connected to the connecting ball on the left side, and a balance sleeve is slidably sleeved on the outer side of the balance bar. The top of the balance sleeve is fixedly connected to the connecting plate. The balance bar and balance sleeve provide a balanced force for the lifting and lowering of the linkage plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model adds a circulating pump to the cooling pool, with a delivery pipe at the output end of the circulating pump extending to the top of the cooling pool. A diversion pipe that drives the nozzle is then installed at the end of the delivery pipe. This allows the cooling water in the cooling pool to circulate, making it fully contact the air for heat exchange, accelerating the cooling efficiency of the cooling water itself, and keeping it at a relatively low temperature to ensure its cooling effect and efficiency on the PVC hose.

[0015] 2. This utility model uses a support frame to erect a top plate above the cooling pool, and then sets multiple hollow cylinders on the top plate. An auxiliary cooling mechanism is set inside the hollow cylinders. The rotating shaft is driven by an electric motor, and the rotating shaft drives the bushing to rotate through the cooperation of the guide rod and the guide block. This drives the stirring rod on the bushing to stir the cooling water. At the same time, it is combined with the air cooling of the fan blades on the bushing, so that the cooling water itself has a higher cooling efficiency. Attached Figure Description

Two guide rollers 3 are installed on the upper end of the filter plate 2. Multiple supports 4 are fixedly connected to the upper edge of the cooling pool 1. A top plate 5 is fixedly connected to the multiple supports 4. A hollow cylinder 6 is fixedly connected inside the top plate 5 and penetrates through the top plate 5. A mesh 7 made of stainless steel is fixedly connected to the inner side of the upper opening of the hollow cylinder 6. The mesh 7 provides protection for the components inside the hollow cylinder 6. A circulation pump 9 is fixedly installed at the bottom of the inner side of the cooling pool 1. A delivery pipe 10 is fixedly connected to the output end of the circulation pump 9. The delivery pipe 10 penetrates the cooling pool 1 and extends to the top of the cooling pool 1. The delivery pipe 10 penetrates the top plate 5 and is slidably connected to the top plate 5. A diversion pipe 11 is fixedly connected to the end of the delivery pipe 10. Multiple nozzles 12 are provided at the bottom of the diversion pipe 11.

[0025] Please see Figure 5 An auxiliary cooling mechanism 8 is provided inside the hollow cylinder 6. The auxiliary cooling mechanism 8 has a cooling effect on the cooling water in the cooling pool 1, keeping it at a relatively low temperature to ensure the cooling effect and efficiency of the PVC hose. The auxiliary cooling mechanism 8 includes multiple fixed rods 81 fixedly connected to the inner wall of the hollow cylinder 6, and a connecting plate 82 is fixedly connected to the multiple fixed rods 81. A motor 83 is fixedly installed at the bottom of the connecting plate 82. A rotating shaft 84 is fixedly connected to the end of the output shaft of the motor 83. A bushing 85 is slidably sleeved on the outer side of the shaft of the rotating shaft 84. A stirring rod 86 is fixedly connected to the lower outer side of the bushing 85. A fan blade 815 is fixedly connected to the middle outer side of the bushing 85.

[0026] Please see Figures 5-6A guide rod 87 is fixedly connected inside the rotating shaft 84, and a guide block 88 is fixedly connected to the inner wall of the bushing 85. The guide rod 87 passes through the guide block 88 and is slidably connected to it. The guide rod 87 and guide block 88 not only allow the bushing 85 to rotate with the rotating shaft 84, but also provide guidance for the axial movement of the bushing 85 along the rotating shaft 84. A ball bearing 89 is provided on the side of the guide block 88, and the ball bearing 89 contacts the inner surface of the rotating shaft 84. The ball bearing 89 reduces the relative friction between the guide block 88 and the rotating shaft 84. A linkage disc 810 is fixedly connected to the upper outer side of the bushing 85.

The electric push rod 812 pushes the connecting ball 811 on the right, thereby pushing the linkage plate 810, which in turn causes the bushing 85 to slide on the outside of the rotating shaft 84. A balance bar 813 is fixedly connected to the connecting ball 811 on the left. A balance sleeve 814 is slidably sleeved on the outside of the balance bar 813, and the top of the balance sleeve 814 is fixedly connected to the connecting plate 82. The balance bar 813 and the balance sleeve 814 provide a balanced force for the lifting and lowering of the linkage plate 810.

[0027] The specific implementation process of this utility model is as follows: During use, the processed PVC pipe passes over the guide roller 3, and the cooling water in the cooling pool 1 cools it. Simultaneously, the circulating pump 9 adds the cooling water from the cooling pool 1 to the distribution pipe 11 through the delivery pipe 10, and then sprays it out through the nozzle 12. After contacting the air, the cooling water falls back into the cooling pool 1, thus exchanging heat with the air, accelerating cooling, and increasing the efficiency of the cooling water itself, keeping it at a relatively low temperature to ensure its cooling effect and efficiency on the PVC hose. In addition, the electric motor... 83 drives the rotating shaft 84 to rotate, and the rotating shaft 84 drives the bushing 85 to rotate through the cooperation of the guide rod 87 and the guide block 88. This drives the stirring rod 86 on the bushing 85 to stir the cooling water. At the same time, in conjunction with the air cooling of the fan blades 815 on the bushing 85, the cooling water itself becomes more efficient. Meanwhile, the electric push rod 812 periodically drives the linkage plate 810 to rise and fall through the connecting ball 811, thereby causing the bushing 85 to move axially in the rotating shaft 84. This expands the stirring range of the stirring rod 86 and further improves the cooling efficiency of the cooling water.
