Description

Technical Field

[0001] The invention relates to the field of water supply pipe cooling machines, and more specifically to an energy-saving HDPE water supply pipe rapid cooling machine. Background Art

[0002] The water pipe cooler is a kind of equipment specially used to cool thermoplastic materials (such as HDPE pipes) during the production process. This cooler can quickly reduce the temperature of the pipe, thereby improving production efficiency and ensuring the physical properties and appearance quality of the pipe.

[0003] In the production process of HDPE pipes, the pipes are formed in the extruder after being heated. The temperature of the heated pipes is relatively high. The rapid cooler sprays the coolant into the pipe surface through the spray system to form water mist, which contacts the high-temperature pipe surface and quickly takes away the heat. For large water pipes, they are completely extruded by the extruder. The water pipes are often immersed in a water tank to directly cool the water pipes. When the extruder pushes the main body of the water pipe into the water tank, if the interval time for the water pipe to be sent into the water tank is long, the water pipe may be deformed due to its own gravity under its own high temperature and softness. At the same time, when the water pipe is sent into the water tank, if the water pipe is not cooled and is in a relatively soft stage, it will rub against the inner wall of the water tank, which will cause scratches on the surface of the water pipe and affect the quality of use. In order to improve the production efficiency and production quality of water pipes, it is necessary to have equipment that can cool the water pipes during the production of water pipes by the extruder.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 9An energy-saving HDPE water supply pipe rapid cooling machine, the cooling machine body 1 includes a cooling machine base 11 and an extruder body 12 fixedly installed on the cooling machine base 11, the extruder body 12 can produce a water pipe body 14, a cooling water tank 13 is also fixedly installed on the cooling machine base 11, a cooling chamber 15 is provided inside the cooling water tank 13, the extruder body 12 is sealed and inserted in the cooling chamber 15, a shaft core rod 2 is fixedly sleeved in the cooling chamber 15, the shaft core rod 2 is sleeved in the pipe of the water pipe body 14, the end of the shaft core rod 2 away from the extruder body 12 passes through the cooling water tank 13, the cooling water tank 13 An external drain pipe 16 is fixedly inserted at the top of one end close to the extruder body 12, and an external water inlet pipe 17 is fixedly inserted at the side of one end of the cooling water trough 13 away from the extruder body 12, and the external water inlet pipe 17 is located below the cooling water trough 13. One end of the shaft core rod 2 close to the extruder body 12 is fixedly connected to a sealing ring 21, a water hole 22 is opened on the shaft core rod 2, and an internal water outlet trough 23 is opened inside the shaft core rod 2. The water hole 22 is connected to the internal water outlet trough 23. The shaft core rod 2 can drain water to the other end of the sealing ring 21 through the internal water outlet trough 23. The diameter of the sealing ring 21 is the same as the inner diameter of the water pipe body 14.

[0031] A guide vane 3 for guiding flow is fixedly arranged in the cooling chamber 15. The guide vane 3 is designed in a spiral shape. An inner guide plate 32 is fixedly sleeved on the outer surface of the shaft core rod 2. The water hole 22 is arranged in the part of the inner guide plate 32 close to the sealing ring 21. The inner wall of the bottom of the cooling chamber 15 is fixedly connected to the guide wheel 18 that assists the movement of the water pipe body 14.

[0032] First, coolant is injected into the cooling chamber 15 through an external water pipe. The coolant enters the cooling chamber 15 from the external water inlet pipe 17 and is then discharged from the external drain pipe 16. When the coolant enters the cooling chamber 15, it will fill the cooling chamber 15. At this time, the extruder body 12 produces a high-temperature water pipe body 14. As the extruder body 12 works, the high-temperature water pipe body 14 will be squeezed into the cooling chamber 15 of the cooling water tank 13. After the outer wall of the high-temperature water pipe body 14 contacts the coolant in the cooling chamber 15, it will be cooled and hardened by the coolant. When the coolant in the cooling chamber 15 enters the high-temperature water pipe body 14, it will cool the inner wall of the high-temperature water pipe body 14. Due to the guide vanes 3, the coolant will spirally flow under the action of the guide blades 3, thereby increasing the flow rate of the coolant and thus improving the cooling effect. At this time, the coolant inside the high-temperature water pipe body 14 will enter the inner water outlet trough 23 through the water hole 22, and be discharged from the cooling water tank 13 from the inner water outlet trough 23. When the coolant enters the cooling water tank 13 from the external water inlet pipe 17, the inner wall and the outer wall of the water pipe body 14 entering the cooling water tank 13 will be cooled at the same time. The water pipe body 14 can be cooled during the production process of the water pipe body 14, and there is no need to wait until the water pipe body 14 is produced and then put into the cooling water tank 13 for cooling, thereby improving the production efficiency of the water pipe body 14.

[0033] In the process of the water pipe body 14 gradually entering the cooling water tank 13, the guide wheel 18 can support the water pipe body 14, assist the extruder body 12 in pushing the water pipe body 14, and at the same time, after the coolant enters the cooling cavity 15, it will flow in a spiral under the action of the guide blade 3. Using the principle of spiral flow, the spiral inner wall can cause the fluid to generate a rotational motion in the cavity. This rotational motion helps to increase the kinetic energy of the fluid, reduce dead zones and low flow rate areas, thereby increasing the overall flow rate. In addition, the spiral cavity can also enhance the heat transfer or mass transfer effect of the fluid, which helps to improve the cooling efficiency;

[0034] It should be noted that water is usually used as the coolant.

[0035] like Figure 2 and Figure 4 As shown, an outer guide plate 31 is fixedly installed on the inner wall of the cooling chamber 15, the guide blade 3 is composed of an inner guide plate 32 and an outer guide plate 31, and the water pipe body 14 shell can pass between the inner guide plate 32 and the outer guide plate 31, and the water pipe can contact the inner guide plate 32 and the outer guide plate 31 when moving.

[0036] When the water pipe body 14 is extruded by the extruder body 12 and gradually enters the cooling water tank 13, as the water pipe body 14 moves, the guide blade 3 moves relative to the water pipe body 14. During the cooling of the water pipe body 14, impurities in the coolant will adhere to the surface of the water pipe body 14. If the water pipe body 14 is completely cooled, these impurities will be completely adhered to the water pipe body 14, which is inconvenient to remove. Therefore, when the water pipe body 14 enters the cooling chamber 15, the inner guide plate 32 and the outer guide plate 31 will act on the inner and outer walls of the water pipe body 14 at the same time, and the impurities attached to the inner and outer walls of the water pipe body 14 due to cooling will be scraped off, thereby ensuring the production quality of the water pipe body 14.

[0037] like Figure 2 and Figure 4 As shown, the blade spacing of the guide blades 3 gradually decreases from left to right, the end of the cooling chamber 15 close to the extruder body 12 is a scraping chamber 19, and the end of the guide blade 3 close to the extruder body 12 is connected to the scraping chamber 19, and the scraping chamber 19 is provided with an anti-distortion component 5 for straightening the water pipe body 14, and the scraping chamber 19 is connected to the external drain pipe 16.

[0038] Since the sudden temperature drop cooling method will cause temperature stress inside the water pipe body 14, increasing the risk of cracks or deformation of the water pipe body 14, when the coolant enters the cooling chamber 15 through the external water inlet pipe 17, the coolant will move along the direction of the spiral guide blade 3. Figure 2As shown in the figure, the closer to the left side the blades are, the smaller the spacing is. Under the condition of the same flow rate, the flow rate of the part with smaller spacing is faster, which leads to faster flow rate of coolant at the left end, and shorter contact time between coolant and inner and outer walls of water pipe body 14. Each part of water pipe body 14 cannot be completely in contact with coolant, which ensures that the temperature of the water pipe itself will not drop suddenly. At the same time, the setting of the blade spacing of the spiral guide blade 3 is that the coolant cooling effect is better closer to one end of the external water inlet pipe 17, and the effect of gradual cooling is achieved, thereby further ensuring the production quality of water pipe body 14.

[0039] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the anti-distortion component 5 includes a swivel 51 rotatably mounted on the inner wall of the scraper chamber 19, and a group of straightening plates 52 are equidistantly arranged on the circumference of the swivel 51. The water flow in the scraper chamber 19 impacts the straightening plates 52 to cause the swivel 51 to rotate, and the straightening plates 52 can contact the outer surface of the water pipe body 14 when the water pipe body 14 enters the cooling chamber 15.

[0040] When the extruder body 12 produces the water pipe body 14, the part of the water pipe body 14 that has not entered the cooling chamber 15 is still soft, and the speed at which the extruder body 12 pushes the water pipe body 14 is slow. At this time, the part of the water pipe body 14 that has just been produced will droop downward due to its own gravity, and when it is sent to the cooling chamber 15 for cooling, it will cause the water pipe body 14 to bend. When the relatively soft part of the water pipe body 14 enters the cooling chamber 15, the blocking ring 21 will first support the water pipe body 14 from the inner wall of the water pipe body 14 to maintain the shape of the inner wall. At the same time, the rotating anti-distortion component 5 will work to continuously shape the outer surface of the water pipe body 14 to ensure the shape of the water pipe body 14, thereby further ensuring the production quality of the water pipe body 14.

[0041] When the anti-distortion assembly 5 is working, the coolant firstly enters the cooling chamber 15 and moves in a Figure 2 As shown in the figure, the coolant flows in a clockwise rotation. When the coolant flows into the scraper chamber 19, the coolant pushes the straightening plate 52 in the scraper chamber 19 to rotate clockwise. Since the straightening plate 52 can contact the outer surface of the water pipe body 14, the outer surface of the water pipe body 14 can be flattened and straightened while the straightening plate 52 rotates, thereby reducing the bending of the water pipe body 14.

[0042] like Figure 2 , Figure 4 and Figure 5As shown, the interior of the cooling chamber 15 is also provided with a spoiler assembly 4 used in conjunction with the guide blades 3, and the spoiler assembly 4 includes a curved pipe 41 fixedly arranged on the outer guide plate 31, and a reciprocating thread is arranged on the curved pipe 41. The rotating sleeve of the part with the reciprocating thread on the curved pipe 41 is provided with an impeller 42, and the direction in which the curved pipe 41 is arranged is opposite to the direction in which the coolant flows.

[0043] The impeller 42 can always contact the outer wall of the water pipe body 14 when rotating through the reciprocating thread on the elbow 41. The part of the impeller 42 used to contact the water pipe body 14 is the knocking plate 421, and the material of the knocking plate 421 is hard silicone rubber.

[0044] like Figure 2 As shown in the figure, after the coolant enters the cooling chamber 15, it will rotate and flow clockwise under the action of the guide vane 3. When the flowing coolant starts to contact the impeller 42, since the direction of the curved pipe 41 is opposite to the direction of the coolant flow, the flowing coolant will push the impeller 42 to rotate. The impeller 42 will reciprocate along the surface of the curved pipe 41 under the action of the reciprocating threads on the curved pipe 41, thereby achieving the effect of disrupting the flow of the coolant, so that each part of the coolant near one end of the external water inlet pipe 17 can completely contact the water pipe body 14, thereby improving the cooling effect of the coolant near one end of the external water inlet pipe 17, further achieving the effect of gradual cooling, and further improving the production quality of the water pipe body 14;

[0045] At the same time, when the impeller 42 is rotating, the part of the impeller 42 that contacts the water pipe body 14 is the knocking plate 421, and the material of the knocking plate 421 is hard silicone rubber. The hard silicone rubber material can ensure the heat resistance of the knocking plate 421. When the knocking plate 421 knocks on the surface of the water pipe body 14, and because the impeller 42 is arranged at the position closest to the external water inlet pipe 17, the water pipe body 14 has been cooled to be hard enough to withstand the action of the knocking plate 421. Without affecting the quality of the water pipe body 14, the attachments on the surface of the water pipe body 14 are knocked, making it convenient for the guide blade 3 to scrape them off.

[0046] like Figure 6 and Figure 7 , Figure 8 and Fig. 9 As shown, a filter part is provided on the straightening plate 52, and the mesh holes allow scale with a size of less than five millimeters to pass through. A descaling component 6 is provided inside the external drain pipe 16, and the descaling component 6 includes a semi-sliding pipe 63 slidably installed on the inner wall of the external drain pipe 16, and the bottom of the semi-sliding pipe 63 is fixedly connected to a shovel plate 64, and a flow hole 65 is opened at the bottom of the shovel plate 64.

[0047] A limiting ring 61 is fixedly installed on the inner wall of the external drainage pipe 16 , and a thrust spring 62 is arranged inside the external drainage pipe 16 . The top of the thrust spring 62 is fixedly connected to the limiting ring 61 , and the bottom of the thrust spring 62 is fixedly connected to the semi-sliding pipe 63 .

[0048] The shovel plate 64 is used to contact one end of the straightening plate 52 to fix the knocking ball group 7, which is composed of a plurality of hard rubber balls, each of which has a diameter greater than five millimeters. Each straightening plate 52 is designed to be inclined.

[0049] like Figure 2 As shown in the figure, when the straightening plate 52 rotates clockwise, in order to ensure that the straightening plate 52 does not affect the normal flow of the coolant under the premise of rotation, the straightening plate 52 is set in a filter shape. When the straightening plate 52 is used for a long time, since the straightening plate 52 is in contact with the water pipe body 14, the heat on the water pipe body 14 will be transferred to the straightening plate 52. If the filter of the straightening plate 52 is blocked, the flow of the coolant will be abnormal, resulting in different coolant flow rates in the scraping chamber 19, resulting in different cooling effects in some areas of the outer surface of the water pipe body 14, thereby affecting the quality of the water pipe body 14 itself in the subsequent cooling process. When the straightening plate 52 rotates clockwise When the semi-sliding tube 63 moves upward, the thrust spring 62 contracts, and the shovel plate 64 moves upward with the semi-sliding tube 63. At the same time, the shovel plate 64 knocks the mesh of the next group of filter screens through each hard rubber ball when passing through the mesh of each filter screen, thereby knocking out the impurities blocked in the mesh and flowing out along the filter screen, thereby optimizing the descaling effect of the structure in the cooling chamber 15, effectively ensuring the stability of the coolant flow rate in the cooling chamber 15, and improving the production quality of the water pipe body 14.

[0050] When the thrust spring 62 contracts, the coolant can enter the outer drain pipe 16 through the filter from the semi-sliding pipe 63 and the flow hole 65, and flow out of the cooling chamber 15. When the thrust spring 62 extends, due to the action of the thrust spring 62, the shovel plate 64 will contact the outer surface of the water pipe body 14 and together with the straightening plate 52 will play a role in shaping the water pipe body 14. At this time, the coolant will flow into the outer drain pipe 16 through the semi-sliding pipe 63, and then be discharged from the cooling chamber 15.

[0051] Usage: First, inject coolant into the cooling chamber 15 through the external water pipe. The coolant enters the cooling chamber 15 from the external water inlet pipe 17 and is discharged from the external drain pipe 16. When the coolant enters the cooling chamber 15, it will fill the cooling chamber 15. At this time, the extruder body 12 produces a high-temperature water pipe body 14. As the extruder body 12 works, the high-temperature water pipe body 14 will be squeezed into the cooling chamber 15 of the cooling water tank 13. After the outer wall of the high-temperature water pipe body 14 contacts the coolant in the cooling chamber 15, it will be cooled and hardened by the coolant. At the same time, the coolant inside the high-temperature water pipe body 14 will enter the inner water outlet trough 23 through the water hole 22, and be discharged from the cooling water trough 13 from the inner water outlet trough 23. When the coolant enters the cooling water trough 13 from the external water inlet pipe 17, the inner wall and the outer wall of the water pipe body 14 entering the cooling water trough 13 will be cooled at the same time. The water pipe body 14 can be cooled during the production process of the water pipe body 14, and there is no need to wait until the water pipe body 14 is produced and then put into the cooling water trough 13 for cooling, thereby improving the production efficiency of the water pipe body 14.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
