Description

Technical Field

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

[0002] During the production process of PVC pipes, after extrusion, they have a high temperature and a soft hardness, and need to be cooled. Otherwise, the pipes cannot be shaped, and are prone to deformation in subsequent processes such as traction, making it impossible to ensure the dimensional accuracy and shape requirements of the pipes. In the existing cooling process of PVC pipes, water cooling is usually adopted. The pipes are pulled into the cooling machine, and multiple cooling water pipes surrounding the pipes are used. Sprayers are installed on the cooling water pipes to spray the pipes, and the cooling water during the spraying process will return to the water tank for recycling. During this process, since the cooling water may contain debris shed from the pipes and dust and other debris accidentally entering at the inlet and outlet of the cooling tank, it is easy to block the sprayers during the water circulation process. Moreover, during the spraying process, the pipes are mostly fixedly installed, making it difficult to rotate around the pipes for spraying. At the same time, it is also difficult to quickly adjust the distance between the spraying pipes and the pipes. When dealing with the cooling of pipes with a larger diameter, the distance between the sprayers and the pipes is too close, which will cause local cooling of the pipe surface to be too fast, resulting in uneven cooling, easily causing internal stress in the pipes, affecting the quality and performance of the pipes, and may even cause problems such as pipe deformation and cracking in severe cases.

Detailed implementation mode

[0019] 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 introduced in detail below with reference to the accompanying drawings.

[0020] The present invention provides a Figures 1 - 12 tube production cooling circulating water treatment system as shown in the figure, including a spray box 1. A feed inlet 2 for pipes is provided on one side of the spray box 1, and a discharge outlet 11 for pipes is provided on the other side of the spray box 1. A water tank 5 is arranged at the bottom of the spray box 1. Water distribution rings are arranged on both sides of the spray box 1 close to the feed inlet 2 and the discharge outlet 11. A circular ring is threadedly connected to both the feed inlet 2 and the discharge outlet 11 (specifically refer to the appendix Figures 2 - 3 ), and an annular elastic material is arranged inside the circular ring. This setting is a conventional technology. When the PVC pipe enters, the annular elastic material can contact and seal the edge of the pipe to prevent the leakage of cooling water; The water distribution ring includes an annular plate 15 and a hollow connection ring 16. The connection ring 16 is rotatably connected to one side of the annular plate 15 through a bearing ring, and a sealing oil seal is arranged between the connection ring 16 and the annular plate 15. A fixed 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 during the subsequent rotation of the connection ring 16, the cooling water will not leak, ensuring that the cooling water can be stably sprayed out through the spray pipe 19 and the nozzle 20; Four spray pipes 19 are arranged in an annular array between the two water distribution rings. Both ends of the four spray pipes 19 are respectively communicated with the two water distribution rings through hoses 40, and a number of nozzles 20 are equidistantly installed on the four spray pipes 19. A rotation mechanism for rotating the water distribution ring and a pipe distance adjustment mechanism for adjusting the pipe distance of the four spray pipes 19 are arranged inside the spray box 1; The bottom of the spray box 1 is provided with a water outlet hole 13. A water outlet pipe 9 is connected between the water outlet hole 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 communicated with the water tank 5 through a pipeline, and a water inlet pipe 7 is connected between the water outlet end of the water pump 8 and the water distribution ring; A controller 3 is installed outside the spray box 1.

[0021] A temperature sensor is installed inside the water tank 5. The temperature of the cooling water inside the water tank 5 is monitored through the temperature sensor. At the same time, a refrigerator is installed outside the water tank 5 (both the temperature sensor and the refrigerator are prior arts, and the position of the refrigerator can be referred to in the attached Figure 1 description. It 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 a conventional temperature control method to ensure that the cooling water can always be maintained within a certain temperature range, prevent the cooling water temperature from being too high, and unable to cool the subsequent pipes, and extend the service time of the circulating water; Furthermore, an observation window for observing the internal state of the spray box 1 is installed on the top of the spray box 1.

[0022] Refer to Figure 5 、 Figures 7 - 12 As shown in the figure, the rotating mechanism includes a forward and reverse motor 4 and an external toothed ring 17 fixed to the connecting ring 16. The forward and reverse motor 4 is installed outside the spray box 1. The transmission shaft of the forward and reverse motor 4 extends into the spray box 1 and is installed with a driving gear 18. The driving gear 18 is meshed and connected with the toothed ring 17.

[0023] Furthermore, the pipe distance adjusting mechanism includes a rotating ring 21 and a guiding ring 22. The rotating ring 21 is located on one side of the connecting ring 16. The guiding 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 spray pipes 19 is fixed on one side of the connecting ring 16. A second slider 34 is slidably connected inside the second slide rail 33. A fixing rod 35 is fixed on one side of the second slider 34. The end of the fixing rod 35 is connected with a fixing sleeve 39. The fixing sleeve 39 is fixed to the outside of the spray pipe 19. A connecting rod 36 is arranged between the second slider 34 and the guiding ring 22. The connecting rod 36 is rotatably connected to the second slider 34 and the guiding ring 22 through a rotating shaft. The fixing method of the fixing sleeve 39 to the spray pipe 19 can adopt common pipe connection methods such as adhesive fixing or interference fit.

[0024] Furthermore, a fixing frame 28 is provided above the gear ring 17, and the fixing frame 28 is fixedly connected to the fixing plate 14, and a transmission rod 44 is rotatably connected to the interior of the fixing frame 28 through a rotating shaft, one end of the transmission rod 44 is in the shape of a screw and is threadedly connected to the guide ring 22, and a strip block 37 is fixed to the other end of the transmission rod 44, and a connecting pipe 47 is sleeved on the outside of the transmission rod 44, and a strip groove 38 matching the strip block 37 is opened inside the connecting pipe 47, and a driven gear 31 is fixed to the end of the connecting pipe 47. Through the cooperation of the strip block 37 and the strip groove 38, the connecting pipe 47 can still drive the transmission rod 44 to rotate while the connecting pipe 47 moves. The transmission rod 44 is threadedly connected to the guide ring 22, and the connecting part can be regarded as a screw. Under the limiting action of the guide column 41, the transmission rod 44 rotates to drive the guide ring 22 to move, and the moving direction of the guide ring 22 can be controlled by controlling the rotation direction of the forward and reverse motor 4. A guide post 41 is fixed to one side of the fixing plate 14 . 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 disposed inside the fixing frame 28 .

[0025] 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; The outside of the connecting tube 47 is rotatably connected to a fixing ring 45 via a bearing, and connecting columns 46 are fixed on both sides of the fixing ring 45. The two connecting columns 46 are respectively located between the two connecting blocks 42. The connecting block 42 is rotatably connected to the first slider 30 and the connecting columns 46 via a rotating shaft. 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 push rod 29 to move 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.

[0026] Furthermore, a ring-shaped groove is provided inside the fixing ring 45, in which a spring 48 is arranged, and the other end of the spring 48 is in contact and extruded with 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 the guide ring 22 from accidentally moving and causing the distance between the water spray pipes 19 to change.

[0027] Reference Figures 1 - 4 and Figure 6As shown in the figure, a filter box 12 is fixedly installed at the inner bottom of the spray box 1. An intermediate groove and side grooves are respectively formed in the middle and on both sides inside the filter box 12. The driving gear 18 is located in the intermediate groove. A driven gear identical to the driving gear 18 is additionally installed on one side of the intermediate groove away from the driving gear 18. A power guide rod is connected between the driving gear 18 and the driven gear. The driven gear is rotationally connected to the filter box 12 through a bearing. The driven gear is meshed and connected with a toothed ring 17 on another water distribution ring. By adding the driven gear and the power guide rod, the forward and reverse motor 4 can drive the driven gear to rotate synchronously while driving the driving gear 18 to rotate, and then synchronously rotate the connecting rings 16 on the two water distribution rings at the same time, so as to improve the stability of the spray pipe 19.

[0028] Furthermore, a main filter screen 25 is installed inside the intermediate groove, and a secondary filter screen 24 is installed inside the side groove. Both the intermediate groove and the side grooves are in a semi-circular structure. A scraper 26 is fixedly installed on the outside of the power guide rod inside the intermediate groove. A detachable semi-circular filter screen 23 is arranged inside the secondary filter screen 24. A fixing disk 27 is fixed at the end of the semi-circular filter screen 23. A connecting disk 6 is rotationally connected to the outside of the fixing disk 27 through a rotating shaft. An insertion hole 10 for the extraction of the connecting disk 6 is formed on the outside of the spray box 1. The connecting disk 6 is threadedly connected to the spray box 1.

[0029] Furthermore, inclined guide plates are fixedly installed on both sides of the filter box 12. The top of the guide plates is in contact with the inner wall of the spray box 1. A sealing ring is arranged between the connecting disk 6 and the spray box 1. The sealing ring can further seal between the connecting disk 6 and the spray box 1 to prevent the leakage of cooling water. The water flow sprayed out by the spray pipe 19 can be completely guided into the filter box 12 through the guide plates. The cooling water guided by the guide plates will sequentially pass through the semi-circular filter screen 23 and the secondary filter screen 24, and then the sundries in the water flow are collected into the semi-circular filter screen 23 to prevent the sundries from blocking the nozzle 20 during the water circulation process and also prevent the sundries from affecting the subsequent cooling effect of the cooling water.

[0030] Through the above technical solutions: During use, the pipe material enters the inside of the spray box 1 from the feed port 2. Then, the controller 3 controls the water pump 8 to extract the cooling water inside the water tank 5 and enter the water distribution ring through the water inlet pipe 7. Then, the cooling water will be sprayed out from the nozzles 20 on the four spray pipes 19 to cool the pipe material. Meanwhile, turn on the forward and reverse motor 4. The forward and reverse motor 4 will drive the driving gear 18, the power guide rod and the driven gear to rotate simultaneously. Cooperating with the toothed ring 17, the connecting rings 16 on the two water distribution rings can be synchronously rotated. Since the spray pipe 19 is installed between the two connecting rings 16, when the pipe material moves inside the spray box 1, it can receive the spraying of the cooling water rotating around the pipe material. Therefore, the uniformity of the pipe material cooling can be improved, and the production quality of the pipe material can be improved. After the cooling water absorbs the heat of the pipe material, the cooling water together with some sundries on the pipe material will enter the filter box 12 for filtration. The filtration of the cooling water is divided into two parts, and the specific process is as follows: The first part of the cooling water directly passes through the main filter screen 25 for filtration. The filtered cooling water will successively pass through the water outlet holes 13 and the water outlet pipe 9 and enter the water tank 5 to participate in the water cycle again; The second part of the cooling water falls into the semi-circular filter screen 23 under the action of the guide plate. Then the filtered cooling water will successively pass through the secondary filter screen 24, the water outlet holes 13 and the water outlet pipe 9 and enter the water tank 5 to participate in the water cycle again; During the process of rotary spraying, while the positive and negative motor 4 drives the power guide rod to rotate, the scraper 26 outside the power guide rod will scrape the sundries filtered inside the main filter screen 25 to the semi-circular filter screens 23 on both sides to ensure that the main filter screen 25 can always maintain high filtration efficiency. At the same time, the sundries in the cooling water can be collected in the semi-circular filter screens 23 to realize the simultaneous filtration of sundries and the collection operation of sundries while rotating and spraying. After separating the connecting disc 6 from the spraying box 1 spirally, the semi-circular filter screen 23 can be directly pulled out, greatly improving the convenience during sundries cleaning; In addition, when the spraying box 1 cools pipes with different diameters and needs to adjust the distance between the nozzle 20 and the pipe, the push rod 29 can be pushed towards the positive and negative motor 4. At this time, the push rod 29 will rotate around the shaft rod 43. Cooperating with the first slide rail 32 and the first slider 30, the connecting block 42 will move towards the guide ring 22, and then synchronously drive the connecting column 46 and the fixed ring 45 to move towards the guide ring 22. After the driven gear 31 meshes with the toothed ring 17, the rotation of the toothed ring 17 can drive the driven gear 31 and the connecting pipe 47 as a whole to rotate. Cooperating with the strip-shaped groove 38 and the strip-shaped block 37, the transmission rod 44 can be driven to rotate. Utilizing the threads on the transmission rod 44 and cooperating with the guide post 41 at the same time, the guide ring 22 can be driven to move; Since the rotating ring 21 is rotationally connected to the guide ring 22 through the bearing ring, during the movement of the guide ring 22, it will not affect the rotation of the water spraying pipe 19. However, during the movement of the guide ring 22, affected by the connecting rod 36, the second slider 34 can slide along the second slide rail 33. Therefore, the distance between the four water spraying pipes 19 can be changed simultaneously. When the distance between the water spraying pipe 19 and the pipe reaches the required value, release the push rod 29. Under the action of the spring 48, the driven gear 31 will reset, and then stop receiving the power of the toothed ring 17 to lock the current position of the guide ring 22 and ensure that the position of the water spraying pipe 19 is the adjusted position; Since the process of adjusting the distance between the water spray pipe 19 and the pipe material 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 power components like electric push rods, hydraulic rods or cylinders, and there are no circuit components in the spray box 1. Therefore, this structure is safe and suitable for long-term use inside the spray box 1.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different 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 of the present invention.
