Description

Technical Field

[0001] The invention relates to the field of pipe cooling and temperature reduction, and in particular to a pipe production cooling circulating water treatment system. Background Art

[0002] During the production process, PVC pipes have a high temperature and are soft after extrusion, so they need to be cooled. Otherwise, the pipes cannot be shaped and are prone to deformation during subsequent pulling steps, making it impossible to ensure the dimensional accuracy and shape requirements of the pipes.

[0003] Existing PVC pipes are usually cooled by water during production. The pipes are pulled into a cooling machine and sprayed with water using multiple cooling water pipes surrounding the pipes. The cooling water is then returned to the water tank for recycling.

[0004] During this process, since the cooling water may contain debris that has fallen off the pipes, as well as dust and other debris that accidentally enter the inlet and outlet of the cooling box, it is easy to clog the nozzles during the water circulation process. In addition, during the spraying process, the pipes are mostly fixedly installed, which makes it difficult to rotate and spray around the pipes. At the same time, the distance between the spray pipes and the pipes is also difficult to adjust quickly. When cooling pipes with larger diameters, the distance between the nozzles and the pipes is too close, which will cause the local surface of the pipe to cool too quickly, resulting in uneven cooling, which can easily cause internal stress in the pipes, affecting the quality and performance of the pipes. In severe cases, it may cause deformation, cracking and other problems of the pipes. Summary of the Invention

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] The present invention provides Figures 1-12 The pipe production cooling circulating water treatment system shown in the figure comprises a spray box 1, a feed port 2 for a pipe is provided on one side of the spray box 1, a discharge port 11 for a pipe is provided on the other side of the spray box 1, a water tank 5 is provided at the bottom of the spray box 1, a water distribution ring is provided on one side of the spray box 1 near the feed port 2 and the discharge port 11, and a circular ring is threadedly connected to the feed port 2 and the discharge port 11 (see the attached figure for details). Figure 2-Figure 3 ), an annular elastic material is provided inside the ring. This setting is a conventional technology. When the PVC pipe enters, the annular elastic material can contact and seal with the edge of the pipe to prevent cooling water leakage;

[0043] The water distribution ring includes an annular plate 15 and a hollow connecting ring 16. The connecting ring 16 is rotatably connected to one side of the annular plate 15 through a bearing ring. An oil seal is provided between the connecting ring 16 and the annular plate 15. A fixing plate 14 is fixed between the annular plate 15 and the inner wall of the spray box 1. Under the action of the oil seal, the cooling water injected into the water distribution ring by the water inlet pipe 7 will be stably stored in the water distribution ring, so that the cooling water will not leak during the subsequent rotation of the connecting ring 16, thereby ensuring that the cooling water can be stably sprayed through the spray pipe 19 and the nozzle 20.

[0044] Four water spray pipes 19 are arranged in a circular array between the two water distribution rings. Both ends of the four water spray pipes 19 are connected to the two water distribution rings respectively through hoses 40, and a number of spray heads 20 are evenly spaced on the four water spray pipes 19. The interior of the spray box 1 is provided with a rotating mechanism for rotating the water distribution ring and a pipe spacing adjustment mechanism for adjusting the pipe spacing of the four water spray pipes 19.

[0045] A water outlet 13 is provided at the bottom of the spray box 1, and a water outlet pipe 9 is connected between the water outlet 13 and the water tank 5. A water pump 8 is installed on one side of the water tank 5. The water inlet end of the water pump 8 is connected to the water tank 5 through a pipe, and the water outlet end of the water pump 8 is connected to the water distribution ring with a water inlet pipe 7;

[0046] A controller 3 is installed outside the spray box 1 .

[0047] A temperature sensor is installed inside the water tank 5 to monitor the temperature of the cooling water inside the water tank 5. At the same time, a refrigerator is installed outside the water tank 5 (both the temperature sensor and the refrigerator are prior art. The location of the refrigerator can be found in the attached manual). Figure 1 , which is located in front of the water tank 5). When the water temperature inside the water tank 5 is too high, the refrigerator will cool the water flow inside the water tank 5. This is an existing conventional temperature control method to ensure that the cooling water can always be kept in a certain temperature range, prevent the cooling water temperature from being too high and unable to cool the subsequent pipes, and extend the use time of the circulating water;

[0048] Furthermore, an observation window for observing the internal state of the spray box 1 is installed on the top of the spray box 1.

[0049] Reference Figure 5 、 Figure 7-12 As shown, the rotating mechanism includes a forward and reverse motor 4 and an external gear ring 17 fixed to a connecting ring 16. The forward and reverse motor 4 is installed on the outside of the spray box 1. The transmission shaft of the forward and reverse motor 4 extends to the inside of the spray box 1 and is installed with a driving gear 18. The driving gear 18 is meshed and connected with the gear ring 17.

[0050] Furthermore, the pipe spacing adjustment mechanism includes a swivel 21 and a guide ring 22. The swivel 21 is located on one side of the connecting ring 16. The guide ring 22 is rotatably connected to the outside of the connecting ring 16 through a bearing ring. A second slide rail 33 corresponding to the four water spray pipes 19 is fixed on one side of the connecting ring 16. The second slide rail 33 is internally slidably connected to a second slider 34. A fixing rod 35 is fixed to one side of the second slider 34. The end of the fixing rod 35 is connected to a fixing sleeve 39. The fixing sleeve 39 is fixed to the outside of the water spray pipe 19. A connecting rod 36 is arranged between the second slider 34 and the guide ring 22. The connecting rod 36 is rotatably connected to the second slider 34 and the guide ring 22 through a rotating shaft. The fixing method of the fixing sleeve 39 and the water spray pipe 19 can adopt common pipeline connection methods such as adhesive fixation or interference fit.

[0051] The guide ring 22 is connected to the driving member 22 by rotating the guide pin 42. The guide ring 22 is connected to the driving member 22 by rotating the guide pin 42. The guide ring 22 is connected to the driving member 22 by rotating the guide pin 42. The guide ring 22 is connected to the driving member 22 by rotating the guide pin 42.

[0052] A guide post 41 is fixed to one side of the fixing plate 14 , and the guide post 41 passes through the guide ring 22 . A shifting assembly for shifting the driven gear 31 toward the gear ring 17 is provided inside the fixing frame 28 .

[0053] Furthermore, the toggle assembly includes a first slide rail 32 symmetrically fixed inside the fixing frame 28 , the first slide rail 32 is slidably connected to the first slider 30 , and a connecting block 42 is provided on one side of the first slider 30 ;

[0054] The exterior of the connecting tube 47 is rotatably connected to a fixing ring 45 via a bearing. Connecting posts 46 are fixed to both sides of the fixing ring 45. The two connecting posts 46 are respectively located between the two connecting blocks 42. The connecting blocks 42 are rotatably connected to the first slider 30 and the connecting posts 46 via a rotating shaft.

[0055] A movable push rod 29 is inserted into the interior of the connecting block 42, and a shaft 43 is installed between one side of the push rod 29 and the fixed frame 28. The top of the push rod 29 is located above the spray box 1. A rectangular hole for the movement of the push rod 29 is opened on the top of the spray box 1. A film of elastic material can be set at the junction of the push rod 29 and the spray box 1. The push rod 29 passes through the film to prevent the cooling water inside the spray box 1 from spraying out when the push rod 29 is pushed.

[0056] Furthermore, a ring-shaped groove is provided inside the fixing ring 45, in which a spring 48 is provided. The other end of the spring 48 contacts and squeezes the fixing frame 28. The spring 48 can make the fixing ring 45 and the driven gear 31 as a whole tend to separate from the gear ring 17 in real time, thereby ensuring that the driven gear 31 will not obtain the power of the gear ring 17 without pulling the push rod 29, so as to avoid accidental movement of the guide ring 22 and cause changes in the spacing between the water pipes 19.

[0057] Reference Figures 1-4 and Figure 6 As shown, a filter box 12 is fixed to the bottom of the interior of the spray box 1, and an intermediate groove and side grooves are respectively provided in the middle and on both sides of the interior of the filter box 12. The driving gear 18 is located in the intermediate groove, and a sub-gear identical to the driving gear 18 is installed on the side of the intermediate groove away from the driving gear 18. A power guide rod is connected between the driving gear 18 and the sub-gear. The sub-gear is rotatably connected to the filter box 12 through a bearing, and the sub-gear is meshed with the gear ring 17 on another water distribution ring. By adding a sub-gear and a power guide rod, the forward and reverse motor 4 can drive the driving gear 18 to rotate while also synchronously driving the sub-gear to rotate, thereby synchronously rotating the connecting rings 16 on the two water distribution rings to improve the stability of the water spray pipe 19.

[0058] Furthermore, a main filter 25 is installed inside the middle trough, and an auxiliary filter 24 is installed inside the side trough. Both the middle trough and the side trough are semicircular in structure. A scraper 26 is fixed to the outside of the power guide rod inside the middle trough. A removable semicircular filter 23 is provided inside the auxiliary filter 24. A fixed disk 27 is fixed to the end of the semicircular filter 23. The outside of the fixed disk 27 is connected to the connecting disk 6 by rotating the shaft. A socket 10 for withdrawing the connecting disk 6 is provided on the outside of the spray box 1, and the connecting disk 6 is threadedly connected to the spray box 1.

[0059] Furthermore, inclined guide plates are fixed on both sides of the filter box 12, and the top of the guide plates contacts the inner wall of the spray box 1. A sealing ring is provided between the connecting plate 6 and the spray box 1. The sealing ring can further seal the connecting plate 6 and the spray box 1 to prevent cooling water leakage. The water flow sprayed from the water pipe 19 can be fully introduced into the filter box 12 through the guide plate. The cooling water guided by the guide plate will pass through the semicircular filter screen 23 and the auxiliary filter screen 24 in turn, and then the debris in the water flow will be collected into the semicircular filter screen 23 to prevent the debris from clogging the nozzle 20 during the water circulation process, and at the same time, it can also prevent the debris from affecting the subsequent cooling effect of the cooling water.

[0060] Through the above technical solution:

[0061] When in use, the pipe enters the interior of the spray box 1 from the feed port 2, and then the controller 3 controls the water pump 8 to extract the cooling water from the water tank 5 and enter the water distribution ring through the water inlet pipe 7. The cooling water will then be sprayed out from the nozzles 20 on the four spray pipes 19 to cool the pipe;

[0062] At the same time, the forward and reverse motor 4 is turned on, which drives the driving gear 18, the power guide rod and the sub-gear to rotate simultaneously, and cooperates with the gear ring 17 to make the connecting rings 16 on the two water distribution rings rotate synchronously. Since the water spray pipe 19 is installed between the two connecting rings 16, the pipe can be sprayed with cooling water rotating around the pipe while moving inside the spray box 1, thereby improving the uniformity of pipe cooling and improving the production quality of the pipe.

[0063] After the cooling water absorbs the heat from the pipe, it and some debris on the pipe will enter the filter box 12 for filtration. The cooling water filtration is divided into two parts. The specific process is as follows:

[0064] The first part of the cooling water directly passes through the main filter 25 for filtration. The filtered cooling water then passes through the water outlet 13 and the water outlet pipe 9 in turn and enters the water tank 5 to participate in the water circulation again.

[0065] The second part of the cooling water falls into the semicircular filter 23 under the action of the guide plate, and then the filtered cooling water passes through the auxiliary filter 24, the water outlet 13, the water outlet pipe 9 and enters the water tank 5, participating in the water circulation again;

[0066] During the rotary spraying process, while the forward and reverse motors 4 drive the power guide rod to rotate, the scrapers 26 on the outside of the power guide rod will scrape the debris filtered inside the main filter 25 into the semicircular filter screens 23 on both sides, so as to ensure that the main filter screen 25 can always maintain high filtering efficiency. At the same time, the debris in the cooling water can also be collected in the semicircular filter screen 23, realizing the simultaneous filtering and debris collection of the cooling water while rotating and spraying. After the connecting plate 6 is spirally separated from the spray box 1, the semicircular filter screen 23 can be directly pulled out, which greatly improves the convenience of debris cleaning.

[0067] In addition, when the spray box 1 is cooling pipes of different diameters and the distance between the nozzle 20 and the pipe needs to be adjusted, the push rod 29 can be pushed in the direction of the forward and reverse motor 4. At this time, the push rod 29 will rotate around the shaft 43, and cooperate with the first slide rail 32 and the first slider 30, so that the connecting block 42 will move in the direction of the guide ring 22, thereby synchronously driving the connecting column 46 and the fixing ring 45 to move in the direction of the guide ring 22. After the driven gear 31 is engaged with the gear ring 17, the gear ring 17 rotates to drive the driven gear 31 and the connecting pipe 47 to rotate as a whole, and cooperates with the strip groove 38 and the strip block 37 to drive the transmission rod 44 to rotate. The thread on the transmission rod 44 cooperates with the guide column 41 to drive the guide ring 22 to move.

[0068] Since the swivel ring 21 and the guide ring 22 are rotatably connected via the bearing ring, the movement of the guide ring 22 does not affect the rotation of the water spray pipe 19. However, during the movement of the guide ring 22, the second slider 34 is affected by the connecting rod 36 to slide along the second slide rail 33, thereby simultaneously changing the spacing between the four water spray pipes 19. When the spacing between the water spray pipe 19 and the pipe reaches the desired spacing, the push rod 29 is released. Under the action of the spring 48, the driven gear 31 is reset, thereby stopping the power from the gear ring 17, thereby locking the current position of the guide ring 22 and ensuring that the position of the water spray pipe 19 is the adjusted position.

[0069] Since the process of adjusting the distance between the water spray pipe 19 and the pipe only requires pushing the push rod 29, and after the adjustment is completed, only the push rod 29 needs to be released, and the position of the water spray pipe 19 will be locked automatically. The adjustment process is convenient, and during this process, no additional power is required, such as electric push rods, hydraulic rods or cylinders and other power components. At the same time, there are no circuit components inside the spray box 1, so the structure is safe and suitable for long-term use inside the spray box 1.

[0070] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
