Description

Technical Field

[0001] The utility model belongs to the technical field of cooling pipes, and particularly relates to a detachable cooling pipe assembly. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent. PVC itself has the characteristics of rainproof, fireproof, antistatic, and easy to mold, so PVC is widely used in the production of handicrafts. In the process of producing PVC film, it is necessary to quickly cool the PVC film after high-temperature operation. For this purpose, a cooling device can be used. A cooling pipe is used in the cooling device. The cooling pipe is composed of a metal pipe. The cooling pipe can quickly cool the liquid, so as to quickly cool the PVC film immersed in the liquid.

[0003] A patent with the publication number of CN212778834U discloses a layered cooling pipe system for a closed cooling tower, including a cooling pipe group, a liquid inlet box, and a liquid outlet box; the cooling pipe group is composed of multiple cooling pipes. The cooling pipe group is arranged in multiple layers from top to bottom. The liquid inlet box and the liquid outlet box are respectively connected to both ends of the cooling pipe. The liquid inlet boxes and the liquid outlet boxes of adjacent layers of the cooling pipe group are arranged staggeredly. A connecting pipe is connected between the liquid outlet box of each layer of the cooling pipe group and the liquid inlet box of the adjacent lower layer of the cooling pipe group; Sealing openings are respectively formed on the sides of the liquid inlet box and the liquid outlet box facing away from the cooling pipe, and sealing door panels are detachably connected to the sealing openings; A filtering component is arranged in the liquid inlet box at the top layer, and the filtering component is stuffed inside the end of the cooling pipe; The filtering component includes a filter screen and a filter housing. The filter screen is fixedly connected inside the filter housing, and the filter housing is threadedly connected to both ends of the cooling pipe.

[0004] During the use of the above cooling pipe system, the filtering component will accumulate impurities in the fluid to be cooled on the filter screen. If the filtering component is not cleaned for a long time, the filter screen will be blocked, and the fluid to be cooled cannot enter the cooling pipe, thus affecting the normal use of the cooling pipe system. The cleaning method of the filtering component of the cooling pipe system is to first remove the sealing door panel from the sealing opening. Then rotate the filter housing to remove the filtering component from the end of the top-layer cooling pipe. After removal, it is cleaned with a brush. Therefore, the cleaning of the filtering component can only occur after the sealing plate is removed. The cleaning process is complex and difficult, greatly wasting the cleaning time of the filtering component. Moreover, frequently disassembling the filtering component is likely to affect the overall stability of the cooling pipe. Summary of the Utility Model

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] As Figures 1 - 6 shown, the technical solution adopted by the present utility model is as follows: A detachable cooling pipe assembly includes a cooling pipe group 3. The cooling pipe group 3 is composed of multiple cooling pipes 31, and both ends of the cooling pipe 31 are communicated with the cavity 2. The cooling pipe group 3 is composed of a cooling pipe group 3 in the horizontal direction and a cooling pipe group 3 in the vertical direction.

[0025] In the horizontal direction: The cooling pipe group 3 is symmetrically arranged in three layers from top to bottom, and each layer is provided with a set of cooling pipe group 3. The liquid inlet pipe 1 is arranged on the right cavity 2 of the uppermost cooling pipe group 3, and the liquid outlet pipe 16 is arranged on the left cavity 2 of the lowermost cooling pipe group 3.

[0026] In the vertical direction:

[0027] The left cavity 2 of the uppermost cooling pipe group 3 in the horizontal direction is communicated with the left cavity 2 of the middle cooling pipe group 3 in the horizontal direction through a cooling pipe group 3 in the vertical direction.

[0028] The right cavity 2 of the middle cooling pipe group 3 in the horizontal direction is communicated with the right cavity 2 of the lowermost cooling pipe group 3 in the horizontal direction through another cooling pipe group 3 in the vertical direction.

[0029] The cooling pipe group 3 cooperates with the cavity 2, presenting an "S" shape as a whole.

[0030] Liquid flows in from the liquid inlet pipe 1 during the cooling process. After being cooled by multiple cooling pipe groups 3, it flows out from the liquid outlet pipe 16. Threads 4 are provided at both ends of the cooling pipe 31, and both ends of the cooling pipe 31 are threadedly connected to the cavity 2. Moreover, a filter screen 15 is installed at the liquid inlet pipe orifice of each cooling pipe 31.

[0031] The coolant that has absorbed heat is transported through the liquid inlet pipe 1 to the corresponding cavity 2. The coolant in the corresponding cavity 2 will flow into the cooling pipe 31 through the filter screen 15, and then flow from the cooling pipe 31 into the next cavity 2. The filter screen 15 will filter the cooling water, and the cooling pipe 31 will cool the cooling water. After being filtered by multiple filter screens 15 and cooled by the cooling pipe 31, the coolant will be discharged from the liquid outlet pipe 16 and flow into the subsequent connected equipment.

[0032] A stepped through-hole is provided on the outer side surface of the cavity 2, and multiple threaded holes 5 are provided on the cavity 2. One side of the cavity 2 is slidably installed with an end cover 7. The end cover 7 is matched with the stepped through-hole. The end cover 7 is slidably and sealingly arranged in the stepped through-hole. A screw 6 is penetrated through the end cover 7, and the screw 6 is in threaded cooperation with the threaded hole 5.

[0033] The end cover 7 is fastened to the cavity 2 through the screw 6 to seal the cavity 2.

[0034] A support rod 8 is fixedly arranged on the inner side surface of the end cover 7. A support ring 9 is fixedly arranged at one end of the support rod 8 away from the end cover 7. A guide piece 10 is fixedly arranged inside the support ring 9.

[0035] A central shaft 12 is fixedly arranged horizontally inside the cavity 2. A sleeve 13 is rotatably arranged on the outer surface of the central shaft 12. A spiral guide chute 11 is provided on the sleeve 13. The guide piece 10 is in sliding cooperation with the spiral guide chute 11. Moreover, the part of the spiral guide chute 11 close to the end cover 7 is in a closed state, so that the guide piece 10 always slides inside the spiral guide chute 11.

[0036] A scraping rod 14 is fixedly arranged on the sleeve 13. The scraping rod 14 is arranged in a "C" shape. The scraping rod 14 is in sliding contact with the inner wall of the cavity 2 and the filter screen 15.

[0037] Since the filter screen 15 is arranged at the liquid inlet pipe orifice of the cooling pipe 31, some impurities will stay on the cavity 2 and the filter screen 15. Therefore, it is necessary to clean the cavity 2 and the filter screen 15.

[0038] During cleaning, the multiple screws 6 are removed by rotation. The end cover 7 is pulled outwards. The end cover 7 will drive the support rod 8 to move, and the support rod 8 will drive the support ring 9 to move away from the filter screen 15. At this time, hold the end cover 7 tightly to prevent the end cover 7 from rotating.

[0039] When the support ring 9 moves, it drives the guide piece 10 to move. When the guide piece 10 moves with the end cover 7, the guide piece 10 slides in the spiral guide chute 11. During this process, the guide piece 10 is in sliding contact and transmission cooperation with the sleeve 13, causing the sleeve 13 to rotate around the central axis 12. The rotation of the sleeve 13 drives the scraping rod 14 to rotate, and the rotation of the scraping rod 14 scrapes against the inner wall of the cavity 2 and the outer side of the filter net 15, thereby scraping off the impurities on the inner wall of the cavity 2 and the outer side of the filter net 15.

[0040] When the guide piece 10 moves to the sealing position of the spiral guide chute 11, the end cover 7 can no longer be stretched.

[0041] Therefore, the end cover 7 can be pulled out and pushed back multiple times, so that the impurities fall into the cavity 2. Then, the impurities are flushed out of the cavity 2 through flushing, and the cavity 2 is cleaned. When the inside of the cooling pipe 31 needs to be cleaned or replaced, the cooling pipe 31 can be rotated to separate the cooling pipe 31 from the cavity 2.

[0042] Working principle

[0043] The coolant that has absorbed heat is transported through the liquid inlet pipe 1 to the initial cavity 2. The coolant in the initial cavity 2 flows into the cooling pipe 31 through the filter net 15, and then flows from the cooling pipe 31 into the next cavity 2. The filter net 15 filters the cooling water, and the cooling pipe 31 cools the cooling water. After being filtered by multiple filter nets 15 and cooled by the cooling pipe 31, the coolant is discharged from the liquid outlet pipe 16 and flows into the subsequent connected equipment.

[0044] Because the filter net 15 is arranged at the relative liquid outlet of each cavity 2, the impurities stay on the cavity 2 and the filter net 15.

[0045] Therefore, it is necessary to clean the cavity 2 and the filter net 15. During cleaning, a plurality of screws 6 are removed by rotation. The end cover 7 is pulled outwards, and the support rod 8 drives the support ring 9 to move away from the filter net 15. At this time, the end cover 7 is grasped to prevent it from rotating.

[0046] When the support ring 9 moves, it drives the guide piece 10 to move. When the guide piece 10 moves with the end cover 7, the guide piece 10 slides in the spiral guide chute 11. During this process, the guide piece 10 is in sliding contact and transmission cooperation with the sleeve 13, causing the sleeve 13 to rotate around the central axis 12. The rotation of the sleeve 13 drives the scraping rod 14 to rotate, and the rotation of the scraping rod 14 scrapes against the inner wall of the cavity 2 and the outer side of the filter net 15, thereby scraping off the impurities on the inner wall of the cavity 2 and the outer side of the filter net 15.

[0047] When the guide piece 10 moves to the sealing position of the spiral guide chute 11, the end cover 7 can no longer be stretched.

[0048] For this purpose, the end cap 7 can be withdrawn and pushed back multiple times, so that impurities fall into the cavity 2. Then, the impurities are flushed out of the cavity 2 through flushing, and the cavity 2 is cleaned. When the inside of the cooling pipe 31 needs to be cleaned or replaced, the cooling pipe 31 can be rotated to separate the cooling pipe 31 from the cavity 2.
