Description

Technical Field

[0001] The invention relates to the field of water treatment, and in particular to a pressure vessel opening device and a pressure vessel winding method thereof. Background Art

[0002] Filter tanks (commonly known as FRP barrels) used to produce composite materials to enhance pressure are widely used in the field of water treatment, especially in large-scale water treatment systems, because of their seamless inner shell, strong pressure bearing capacity, and environmental hygiene. In recent years, with the development of the economy, the forms of such containers have begun to change: in addition to the traditional upper opening and lower opening models, there are also shoulder openings and barrel side openings (which may be one or more, and may be in the same direction or in different directions). Because of these changes, water treatment processes have been developed, sensors have been applied, and different types of water treatment requirements have been met.

[0003] Currently in the filter canister, the composite material reinforcement layer yarn is continuously and uninterruptedly wound around the outer surface of the inner liner layer. Since the hole-opening operation requires piercing through the composite material reinforcement layer on the container, the wound yarn will be cut off, which will greatly affect the strength. When the filter canister is subjected to higher pressure, the opening is prone to leakage or even bursting due to insufficient strength, making the product unusable and, in severe cases, causing property losses to users. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the existing hole opening operation needs to pierce through the composite material reinforcement layer on the container, so that the strength is greatly affected, and the opening is prone to leakage or even bursting due to insufficient strength, making the product unusable and even causing property loss to the user in severe cases. A pressure vessel opening device and a pressure vessel winding method are provided.

[0007] In this solution, the above-mentioned structural form is adopted, and the bottom yarn can slide to both sides through the conical part to avoid the final punching, so that the bottom yarn will not be cut off by subsequent processing, effectively enhancing the pressure bearing capacity at the opening, thereby achieving a more reliable and safer overall structure of the pressure vessel opening device. At the same time, there are fewer post-processing steps and no padding operation is required, so that the production process is continuous and the post-processing is simple, which greatly improves the production efficiency of the pressure vessel opening device and also improves the safety of the pressure vessel opening device.

[0008] Preferably, the bottom of the conical portion has an insert block, and one end of the embedded portion facing the conical portion has a slot, and the insert block is embedded in the slot.

[0010] Preferably, the adapter has a through hole, and the embedding portion is embedded in the through hole.

[0012] Preferably, one end of the through hole facing the insert has a step, and the outer peripheral surface of the embedded portion has a supporting portion extending outward, and the supporting portion is embedded in the step.

[0013] In the present solution, the above-mentioned structural form is adopted, so that the embedded part can avoid the occurrence of displacement and dislocation during use, thereby achieving higher stability of the pressure vessel opening device; and higher installation positioning accuracy.

[0014] Preferably, the inner liner layer has a mounting frame recessed along the inner direction thereof, and the adapter is connected to the mounting frame from the outside to the inside.

[0015] In this solution, the above-mentioned structural form is adopted, and the adapter is installed on the mounting frame from the outside of the inner liner layer, thereby realizing the installation of the adapter without the need for installation operations from the inside of the inner liner layer, making the installation process of the adapter simple, fast and efficient.

[0016] Preferably, the pressure vessel opening device further comprises a sealing ring, and the sealing ring is pressed between the mounting frame and the adapter.

[0017] In this solution, the above-mentioned structural form is adopted to effectively enhance the sealing effect of the pressure vessel opening device through the sealing ring, which is beneficial to improving the airtightness of the pressure vessel during use.

[0018] A pressure vessel winding method, characterized in that it utilizes the pressure vessel opening device as described above, and the pressure vessel winding method comprises the following steps:

[0051] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0052] like Figure 1-5 As shown, the present application provides a pressure vessel opening device, which includes an inner liner layer 1, a transition piece 2 and an insert 3, the transition piece 2 is connected to the inner liner layer 1, the insert 3 includes an embedding portion 32 and a conical portion 31, the embedding portion 32 is detachably connected to the transition piece 2, the conical portion 31 is detachably connected to the embedding portion 32, and the conical portion 31 protrudes from the outer surface of the inner liner layer 1.

[0053] The inner liner layer 1 is provided with an opening, and the adapter 2 is installed at the opening and connected to the inner liner layer 1, and is connected to the outside through the adapter 2. The insert 3 is detachably connected to the adapter 2 through the embedding portion 32, and the embedding portion 32 and the conical portion 31 can be separated. The composite material reinforcement layer includes a bottom layer yarn 10 and a surface layer yarn 20, and the bottom layer yarn 10 and the surface layer yarn 20 need to be respectively wound on the outer surface of the inner liner layer 1. Since the conical portion 31 protrudes from the outer surface of the inner liner layer 1, when the bottom layer yarn 10 is wound, the conical portion 31 can slide the bottom layer yarn 10 to both sides to avoid the final punching, so that the bottom layer yarn 10 will not be cut off by subsequent processing, effectively enhancing the pressure bearing capacity at the opening, so as to achieve a more reliable and safe overall structure of the pressure vessel opening device. At the same time, there are fewer post-processing steps, and no padding operation is required, so that the production process is continuous and the post-processing is simple, which greatly improves the production efficiency of the pressure vessel opening device and also improves the safety of the pressure vessel opening device.

[0054] The bottom of the cone portion 31 has an insert block 311, and the end of the embedded portion 32 facing the cone portion 31 has a slot 321, and the insert block 311 is embedded in the slot 321. The insert block 311 is inserted into the slot 321 to achieve mutual cooperation, and installation and removal are very convenient; at the same time, the insert block 311 and the slot 321 have a positioning function, so that the cone portion 31 is installed with high precision, ensuring that the subsequent hole opening will not cut off the bottom yarn 10, and the insert block 311 and the slot 321 have a simple structure and are easy to manufacture.

[0055] The adapter 2 has a through hole 21, and the embedded portion 32 is embedded in the through hole 21. The embedded portion 32 is inserted into the through hole 21 to achieve mutual cooperation between the embedded portion 3 and the adapter 2, and installation and removal are very convenient; at the same time, the through hole 21 and the embedded portion 32 have a positioning function, so that the adapter 2 can be installed accurately, ensuring that the subsequent hole opening will not cut off the bottom yarn 10 and the subsequent hole opening operation is accurate. Among them, the shape of the embedded portion 32 is cylindrical.

[0056] The through hole 21 has a step 22 at one end facing the insert 3, and the outer peripheral surface of the embedded portion 32 has a supporting portion extending outward, and the supporting portion is embedded in the step 22. The embedded portion 32 is supported against the step 22 by the supporting portion, so that the embedded portion 32 avoids the occurrence of displacement and dislocation during use, and realizes higher stability of the pressure vessel opening device; and higher installation positioning accuracy.

[0057] The inner liner layer 1 has a mounting frame 11 that is recessed along the inner direction thereof, and the adapter 2 is connected to the mounting frame 11 from the outside to the inside. When installing the adapter 2, the adapter 2 is installed on the mounting frame 11 from the outside of the inner liner layer 1, thereby achieving installation of the adapter 2 without the need to perform installation operations from the inside of the inner liner layer 1, making the installation process of the adapter 2 simple, fast and efficient.

[0058] The pressure vessel opening device also includes a sealing ring 4, which is pressed between the mounting frame 11 and the adapter 2. The sealing ring 4 effectively enhances the sealing effect of the pressure vessel opening device, which is beneficial to improving the airtightness of the pressure vessel during use. The sealing ring 4 is arranged in the mounting frame 11 and between the mounting frame 11 and the adapter 2, and the mounting frame 11 plays a good role in limiting and fixing the sealing ring 4. The sealing ring 4 is in the shape of a ring, has a circular cross section, and is made of rubber.

[0059] The present embodiment also discloses a pressure vessel winding method, which utilizes the pressure vessel opening device as described above, and the pressure vessel winding method comprises the following steps: step S1, winding the bottom yarn 10 around the outer surface of the inner liner layer 1, wherein when the wound bottom yarn 10 covers the conical portion 31, the bottom yarn 10 slides to both sides of the conical portion 31 to avoid it; step S2, taking out the conical portion 31; step S3, winding the surface yarn 20 around the outer surface of the bottom yarn 10 and the embedded portion 32; step S4, punching holes in the surface yarn 20 at positions corresponding to the embedded portion 32.

[0060] Through the above steps, when the bottom yarn 10 is wrapped around and covered on the cone portion 31, the bottom yarn 10 slides to both sides of the cone portion 31, thereby avoiding the position where the opening is required. The advantage of this is that when the hole is finally punched, the bottom yarn 10 will not be processed, so that the bottom yarn 10 is continuous and has higher strength. The pressure bearing capacity at the opening is effectively enhanced, so that the overall structure of the pressure vessel opening device is more reliable and safe. At the same time, there are fewer post-processing steps and no need for cloth padding operation, which makes the production process continuous and the post-processing simple, greatly improving the production efficiency of the pressure vessel opening device and also improving the safety of the pressure vessel opening device.

[0061] After the bottom yarn 10 is wound, it is still necessary to continue to wind the surface yarn 20 of the composite material reinforcement layer. If there is only the bottom yarn 10 but no surface yarn 20, the pressure vessel opening device still has relatively weak places and is difficult to withstand high pressure continuously. After the bottom yarn 10 is wound, the conical part 31 will be removed and the embedded part 32 will be retained. The embedded part 32 will no longer be exposed on the outer surface of the liner layer 1. In this way, the outer surface of the liner layer 1 will be completely covered by the winding of the surface yarn 20 to strengthen the weak link, thereby increasing the pressure bearing capacity of the pressure vessel opening device.

[0062] After the surface yarn 20 is wound and solidified, the surface yarn 20 can be punched. Because there is no need to punch the bottom yarn 10, the punching operation is very convenient.

[0063] After step S4, step S5 is also included, and step S5 is to take out the embedded part 32. After the punching is completed, the embedded part 32 of the insert 3 can be taken out through the hole, so that the finished product processing process is completed. There are fewer post-processing steps, and no padding operation is required, so that the production process is continuous and the post-processing is simple, which greatly improves the production efficiency of the pressure vessel opening device; at the same time, it also improves the safety of the pressure vessel opening device.

[0064] In step S1, the bottom yarn 10 is spirally wound on the outer surface of the liner layer 1. In step S3, the surface yarn 20 is circumferentially wound on the outer surface of the bottom yarn 10. The bottom yarn 10 is spirally wound and covered. If there is only the spirally wound bottom yarn 10, the straight section of the liner layer 1 still has relatively weak places and it is difficult to withstand high pressure continuously. The surface yarn 20 is circumferentially wound on the outer surface of the liner layer 1 to strengthen the weak link. The part with weaker pressure bearing capacity on the liner layer 1 is strengthened to meet the predetermined pressure bearing requirements, thereby improving the safety of the pressure vessel opening device.
