Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to a pipeline mechanism with two materials switchable. Background Technique

[0002] The double-pipeline parallel conveying flow path for the final polymerization reaction usually refers to that in some chemical reactions or industrial processes, in order to improve efficiency or throughput, two parallel pipeline systems are used to convey reactants or products. This design can increase the overall flow rate of the system, reduce the load on a single pipeline, and may help balance the distribution of fluids in the system. In a reaction device, two or more pipelines are arranged in parallel, so that a higher conveying flow rate can be achieved. Each pipeline can operate independently, but they jointly process reactants or products. In order to ensure the flow balance of each pipeline, a reasonable flow path layout and control system usually need to be designed. If the flow is not balanced, it may cause some pipelines to be overloaded while other pipelines are not fully utilized.

[0003] The double-material pipeline is mainly for flexible switching under different materials or reaction conditions. This is very useful for processes that need to handle different raw materials or carry out different reactions at different time periods.

[0004] However, when a fault occurs or maintenance is required in one of the existing double-material pipelines, the other pipeline also has to suspend operation, which increases the production downtime and reduces the overall reliability of the system; therefore, it does not meet the existing requirements, and for this reason, we propose a pipeline mechanism with two materials switchable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that when a failure occurs or maintenance is required in one of the existing dual-material pipelines, the other pipeline also has to stop working, which increases the production downtime and reduces the overall reliability of the system. Please refer to Figures 1-4 , a dual-material switchable pipeline mechanism, including a main pipeline 110, a first material pipeline 111, and a second material pipeline 112. A switching cylinder 113 is installed at the end of the main pipeline 110. The first material pipeline 111 is inserted into the side of the switching cylinder 113, and the second material pipeline 112 is inserted into the upper side of the switching cylinder 113. A plurality of fixing rings 114 for external fixed installation are sleeved outside the main pipeline 110, the first material pipeline 111, and the second material pipeline 112. A positioning plate 115 is installed on the side of the fixing ring 114. Feeding ports 120 are opened in both the first material pipeline 112 and the second material pipeline 113. A switching cavity 121 is opened in the switching cylinder 113. The switching cavity 121 is communicated with the feeding port 120, and a switching component 210 is arranged in the switching cavity 121.

[0024] The switching component 210 includes a fixing plate 211 installed in the switching cavity 121. A through port 212 corresponding to the feeding port 120 is opened in the fixing ring 114. A control ring 213 is installed on the side of the fixing plate 211. A blocking blade 214 for opening and closing the through port 212 is installed on the fixing ring 114. The blocking blade 214 is located inside the control ring 213. A control rod 215 is connected between the control ring 213 and the blocking blade 214. A first limiting rod 216 is installed on the control ring 213, a second limiting rod 217 is installed on the fixing plate 211, and a third limiting rod 218 is installed on the blocking blade 214. One end of the control rod 215 is movably inserted into the first limiting rod 216, the other end of the control rod 215 is movably inserted into the third limiting rod 218, and the blocking blade 214 is movably inserted into the second limiting rod.

[0025] The barrier vanes 214 are arranged in five groups. The five groups of barrier vanes 214 are arranged in a ring with the through port 212 as the center. A sealing strip 230 is installed outside the barrier vanes 214, and the sealing strip 230 is set as a rubber strip. A guide rod 220 is installed on the fixing plate 211. A guide groove 221 corresponding to the guide rod 220 is formed on the control ring 213. The guide rod 220 is slidably inserted into the guide groove 221. A driving ring 222 for driving the control ring 213 is sleeved outside the control ring 213. A driving groove 223 corresponding to the driving ring 222 is formed outside the switching cylinder 113. The driving ring 222 is movably inserted into the driving groove 223.

[0026] When a material pipe needs to be maintained, rotate the corresponding driving ring 222. As the driving ring 222 rotates, it drives the control ring 213 to rotate coaxially, so that the control connecting rod drives the barrier vanes 214 to rotate along the rotation direction of the control ring 213. Thus, the barrier vanes 214 are closely attached to each other, so as to close the corresponding through port 212 and the feeding port 120. At this time, the material pipe can be maintained. After the maintenance is completed, rotate the driving ring 222 in the reverse direction again to control the barrier vanes 214 to reconnect the through port 212 with the feeding port.

[0027] In this embodiment: Through the design of the control ring 213 and the driving ring 222 in the switching assembly 210, the switching operation becomes more flexible and convenient. The cooperation between the control ring 213 and the barrier vanes 214 makes the opening and closing operation of the through port 212 more accurate and reliable. Thus, when a pipeline fails or needs to be maintained, the other pipeline can still operate normally. Even if one pipeline needs to be shut down, the production process of the whole system will not be completely interrupted, thereby improving the overall reliability and continuity of the system. At the same time, the sealing strip 230 installed on the barrier vanes 214 can effectively ensure the sealing performance in the closed state, preventing material leakage or cross-contamination.

[0028] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the situation of inaccurate alignment or loose engagement during the operation process, which may affect the switching effect and the sealing performance of the system. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1-4 . The switching assembly 210 is arranged in two groups. One group of switching assemblies 210 is arranged on the side of the first material pipe 111, and the other group of switching assemblies 210 is located on the side of the second material pipe 112. By dividing the switching assembly 210 into two groups, each group corresponding to a material pipe, the design is more in line with the actual needs. Each group of switching assemblies 210 can be operated independently to achieve precise control of each material pipe. Clamping blocks 122 are installed outside the first material pipe 111 and the second material pipe 112. Clamping grooves 123 corresponding to the clamping blocks 122 are formed in the switching cylinder 113. The clamping blocks 122 are engaged with the clamping grooves 123.

[0029] In this embodiment, the design of the clamping block 122 and the clamping groove 123 can simplify the installation and disassembly process of the switching component 210, making the maintenance operation more convenient, effectively solving the problems of inaccurate alignment or loose clamping during the operation process, improving the switching effect and the sealing performance of the system. It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0030] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
