Description

Technical Field

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

[0002] In the production of polypropylene pipes, the cooling process is crucial. Traditional cooling methods have many shortcomings. For example, natural cooling is inefficient, severely impacting production efficiency. Simple cooling devices often fail to ensure uniform cooling around the circumference and axis of the pipes, leading to quality problems such as localized deformation and uneven internal stress, thus reducing product quality. Furthermore, with increasing environmental requirements, issues such as water waste and poor recycling of cooling water urgently need to be addressed. Moreover, in the trend towards automated production, there is a lack of intelligent devices capable of real-time monitoring and precise control of cooling effects. Therefore, a new type of cooling spray device for polypropylene pipe production is urgently needed to improve cooling efficiency, ensure pipe quality, conserve resources, and achieve intelligent management.

[0003] A Chinese patent with publication number CN218700595U discloses a rapid cooling polypropylene production equipment, including a support 1. A rectangular groove 4 is provided on the upper end of the support 1, and a chain conveyor belt 2 is fixedly installed in the rectangular groove 4. Each chain plate of the chain conveyor belt 2 has an arc-shaped groove 6 evenly and longitudinally provided. The water flow falling from the spray is collected in the arc-shaped groove 6, so that the back of the polypropylene product is pressed against the water surface.

[0004] The problem with the aforementioned technologies is that the coolant sprayed onto the pipes can only collect at the bottom of the device to cool the very bottom of the pipes, resulting in low reuse rate and low overall cooling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cooling spray device for the production of polypropylene pipes. By using this device, the problem that the coolant sprayed onto the pipes can only collect at the bottom of the device to cool the bottom of the pipes, resulting in low reuse rate and low cooling efficiency of the entire cooling process is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling spray device for polypropylene pipe production, comprising an outer shell, an inner pipe installed inside the outer shell, a water tank installed at the upper end of the outer shell, a spray assembly installed inside the inner pipe, a water-spraying assembly between the outer shell and the inner pipe, multiple flow grooves opened on the inner pipe, and the water-spraying assembly including two rotating rings, both rotating rings being rotatably sleeved at both ends of the inner pipe, multiple agitator plates installed between the two rotating rings, the agitator plates being located between the outer shell and the inner pipe, a gear sleeve fixedly sleeved on the outer side of one of the rotating rings, a gear meshing on one side of the gear sleeve, a motor installed on one side of the gear, the motor being mounted through the outer shell, and the drive end of the motor being fixedly connected to the gear.

[0007] The spray assembly sprays coolant onto the pipes placed on the inner tube. The coolant slides down the pipes into the flow channel, then enters the space between the outer shell and the inner tube. The motor is started, and the drive end of the motor drives the gear to rotate, which in turn drives the gear sleeve to rotate, causing the rotating ring to rotate. This, in turn, drives the agitator plate to rotate. The agitator plate causes the coolant accumulated between the outer shell and the inner tube to flow, allowing the collected coolant to return to the inner tube from the flow channel and be sprayed onto the underside of the pipes. This fully utilizes the coolant and makes the cooling effect on the pipes better.

[0008] Preferably, the flow channel is truncated pyramidal in shape, with the end having a smaller bottom area facing the inner surface of the inner tube.

[0009] The coolant between the outer casing and the inner tube can accumulate along the flow channel, forming a water flow that moves toward the inner surface of the inner tube.

[0010] Preferably, a connecting ring is installed on the side of the two rotating rings that are far apart from each other, and the connecting ring is rotatably connected to the outer casing.

[0011] The connecting ring serves to limit the rotational position of the rotating ring.

[0012] Preferably, the spray assembly includes a guide plate located at the upper end of the inner side of the inner tube, and multiple spray heads installed on the lower side of the guide plate. Water pipes are installed at both ends of the guide plate, and the ends of the two water pipes away from the guide plate are connected to the water tank.

[0013] The coolant in the water tank flows through the water pipes to the baffle plate, and then is sprayed onto the pipes through the spray nozzles.

[0014] Preferably, the lower end of the outer shell is provided with multiple liquid outlet holes, and a liquid storage tank is installed on the lower side of the outer shell, with the liquid storage tank located below the liquid outlet holes.

[0015] Excess coolant enters the reservoir through the outlet hole, where it is stored for later recycling.

[0016] Preferably, a cooler and a water pump are installed on one side of the outer casing. The cooler is located above the water pump and the cooler and the water pump are connected. A second water pipe is installed at the upper end of the cooler, and the end of the second water pipe away from the cooler is connected to a water tank. A third water pipe is installed at the lower end of the water pump, and the end of the third water pipe away from the water pump is connected to a liquid storage tank.

[0017] Excess coolant stored in the storage tank is drawn into the cooler by the water pump. The cooler cools the recovered coolant and then sends it to the water tank for recycling.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model proposes a cooling spray device for polypropylene pipe production. The spray assembly sprays coolant onto the pipe placed on the inner tube. The coolant slides down the pipe into the flow channel and then enters the space between the outer shell and the inner tube. The motor is started, and the drive end of the motor drives the gear to rotate, which in turn drives the gear sleeve to rotate, causing the rotating ring to rotate. This, in turn, drives the agitator plate to rotate. The agitator plate causes the coolant accumulated between the outer shell and the inner tube to flow, so that the accumulated coolant returns from the flow channel to the inner tube and is sprayed onto the lower side of the pipe. This fully utilizes the coolant and makes the cooling effect on the pipe better. Attached Figure Description

The inner pipe 2 has multiple flow channels 21. The water-spraying assembly 5 includes two rotating rings 51, each rotatably sleeved at both ends of the inner pipe 2. Multiple agitator plates 52 are installed between the two rotating rings 51 and the inner pipe 2. A gear sleeve 53 is fixedly sleeved on the outer side of one of the rotating rings 51. A gear 54 is meshed on one side of the gear sleeve 53, and a [missing information - likely a type of agitator] is provided on one side of the gear 54. Motor 55 is mounted through the outer casing 1. The drive end of motor 55 is fixedly connected to gear 54. Spray assembly 4 sprays coolant onto the pipe placed on inner tube 2. The coolant slides down the pipe to flow channel 21 and then enters the space between outer casing 1 and inner tube 2. When motor 55 is started, the drive end of motor 55 drives gear 54 to rotate, which in turn drives gear sleeve 53 to rotate, causing rotating ring 51 to rotate, which in turn drives agitator 52 to rotate. Agitator 52 causes the coolant accumulated between outer casing 1 and inner tube 2 to flow, so that the accumulated coolant returns from flow channel 21 to inner tube 2 and is sprayed onto the lower side of the pipe, making full use of the coolant and improving the cooling effect of the coolant on the pipe.

[0032] Combination Figures 4-6The flow channel 21 is shaped like a frustum and the end with the smaller bottom area faces the inner surface of the inner tube 2. The coolant between the outer shell 1 and the inner tube 2 can gather along the flow channel 21 to form a water flow moving towards the inner surface of the inner tube 2. A connecting ring 511 is installed on the side of the two rotating rings 51 that are far apart from each other. The connecting ring 511 is rotatably connected to the outer shell 1. The connecting ring 511 plays the role of limiting the rotation position of the rotating ring 51.

[0033] Combination Figure 2 , Figure 7 The spray assembly 4 includes a guide plate 41, which is located at the upper end of the inner tube 2. Multiple spray heads 42 are installed on the lower side of the guide plate 41. Water pipes 43 are installed at both ends of the guide plate 41. The ends of the two water pipes 43 away from the guide plate 41 are connected to the water tank 3. The coolant in the water tank 3 flows to the guide plate 41 through the water pipes 43 and is then sprayed onto the pipe through the spray heads 42.

[0034] Combination Figure 1 , Figure 8 The lower end of the outer casing 1 has multiple liquid outlet holes 11. A liquid storage tank 12 is installed on the lower side of the outer casing 1, and the liquid storage tank 12 is located below the liquid outlet holes 11. Excess coolant enters the liquid storage tank 12 through the liquid outlet holes 11. The liquid storage tank 12 stores the excess coolant for later recycling. A cooler 6 and a water pump 7 are installed on one side of the outer casing 1. The cooler 6 is located above the water pump 7 and the cooler 6 and the water pump 7 are connected. A second water pipe 61 is installed at the upper end of the cooler 6. The end of the second water pipe 61 away from the cooler 6 is connected to the water tank 3. A third water pipe 71 is installed at the lower end of the water pump 7. The end of the third water pipe 71 away from the water pump 7 is connected to the liquid storage tank 12. The excess coolant stored in the liquid storage tank 12 is sucked into the cooler 6 by the water pump 7. The cooler 6 cools the recycled coolant and then transports it to the water tank 3 to achieve recycling.

[0035] Working principle: The spray assembly 4 sprays coolant onto the pipe placed on the inner tube 2. The coolant slides down the pipe into the flow channel 21, and then enters the space between the outer shell 1 and the inner tube 2. The motor 55 is started, and the drive end of the motor 55 drives the gear 54 to rotate, which in turn drives the gear sleeve 53 to rotate, causing the rotating ring 51 to rotate, which in turn drives the stirring plate 52 to rotate. The stirring plate 52 causes the coolant accumulated between the outer shell 1 and the inner tube 2 to flow, so that the accumulated coolant returns from the flow channel 21 back into the inner tube 2 and is sprayed onto the lower side of the pipe, making full use of the coolant and improving the cooling effect of the coolant on the pipe.
