Description

TECHNICAL FIELD

[0001] The utility model mainly relates to pipeline switching technical field, concretely relates to a kind of expansion pipeline switching device for ultrapure water. BACKGROUND

[0002] In many industries relying on ultrapure water, such as electronic chip manufacturing, biological medicine research and production, high-end optical lens cleaning and other fields, the quality and supply of ultrapure water directly affect product quality and production efficiency. With the rapid development of science and technology and the dynamic changes of market demand, the production scale and process requirements of these industries are constantly adjusted, and the flexibility of ultrapure water system capacity is challenged.

[0003] Early ultrapure water supply systems are mostly designed with fixed capacity. Once a set of ultrapure water machine is built, its capacity is basically constant. For example, a traditional 500-ton ultrapure water machine is usually composed of a fixed number of production units simply connected in parallel. If the initial production scale of the enterprise is small, only 300 tons of capacity is needed, and the remaining 200 tons of capacity equipment is idle, resulting in waste of equipment purchase cost, space occupation, and high long-term maintenance cost of idle equipment.

[0004] When the enterprise develops and needs to increase the capacity from 300 tons to 700 tons, the expansion process of the traditional system is extremely complex. It usually needs to be re-laid and re-laid, which involves a large amount of pipe welding and cutting operations, not only the construction period is long, which affects the normal production of the enterprise, but also the transformation process is easy to introduce impurities, which threatens the quality of ultrapure water. At the same time, the compatibility of the new equipment with the original system is difficult to guarantee, which may cause the system to run unstable and frequently malfunction.

[0005] On the contrary, when the enterprise needs to reduce the capacity from 800 tons to 300 tons due to market fluctuations, partial plant shutdown and other reasons, the traditional system lacks an effective switching mechanism. It is not convenient to separate the redundant equipment from the running system, and only the redundant equipment can continue to idle, causing great waste of energy and increasing the operating cost of the enterprise.

[0040] Working principle:

[0041] In the early stage of the project, when the demand for ultrapure water is 300 tons, the collecting pipe 2 on the base 1 plays a key role. The operator opens the valve 3 on the water inlet pipe 6 of each group of ultrapure water production devices, and each group of ultrapure water production devices is connected to the water inlet pipe 6 through the water outlet pipe assembly 7. The connecting corrugated pipe 72 in the water outlet pipe assembly 7 connects the output end of the ultrapure water production device, and the docking pipe 71 is connected to the water inlet pipe 6 under the action of the docking mechanism 8. The hydraulic cylinder one 81 in the docking mechanism 8 pushes the moving block 82, the guide block 85 on the moving block 82 slides along the guide rail 84, and the fixed frame 83 and the docking pipe 71 fixed thereon are connected to complete the docking.

[0042] When the docking pipe 71 and the water inlet pipe 6 are aligned, the sealing mechanism 9 starts to work, the hydraulic oil is injected into the cylinder body of the hydraulic cylinder two 92, and the piston rod is pushed out. The end of the piston rod is movably connected with the connecting rod 93, and can rotate at a certain angle. As the piston rod extends, the connecting rod 93 starts to rotate around the rotating support point on the mounting frame 91. The middle segment of the connecting rod 93 is fixedly provided with the mounting block 94, which moves with the connecting rod 93 during rotation. The top end of the supporting column one 42 is provided with a sealing block 95 symmetrically arranged thereon, and the two sealing blocks 95 gradually fit together as the mounting block 94 approaches. The sealing block 95 is made of high elasticity and corrosion resistance rubber material, and the surface is specially treated, which has good sealing performance. When the two sealing blocks 95 are tightly fitted, a tight sealing line is formed, which ensures that the ultrapure water will not leak when flowing through the docking place, and the ultrapure water produced by the three groups of equipment flows into the water pipe 5 from the water outlet of the collecting pipe 2 for production use.

[0043] Expansion operation: if the production capacity needs to be increased from 300 tons to 700 tons in the later period, two groups of ultrapure water production devices are added. The operator pushes the water outlet pipe assembly 7 of the two groups of devices to the automatic docking device 4, and uses the docking mechanism 8 and the sealing mechanism 9 of the automatic docking device 4 to repeat the above docking and sealing steps, so that the two groups of newly added devices are connected to the system. The water produced by the ultrapure water production device flows into the collecting pipe 2 through the water outlet pipe assembly 7 and the water inlet pipe 6, and finally realizes the production capacity of 700 tons.

[0044] Capacity reduction: when the ultrapure water system has been expanded to 800 tons of capacity, and only 300 tons of capacity is needed due to production adjustment in the workshop, the operator reverses the operation of the automatic docking device 4. First, the hydraulic cylinder two 92 of the sealing mechanism 9 is retracted to separate the sealing block 95, and then the hydraulic cylinder one 81 of the docking mechanism 8 is operated to drive the docking pipe 71 to separate from the water inlet pipe 6. Subsequently, the valves 3 on the water inlet pipes 6 of the remaining 5 groups of equipment are closed, the water outlet pipe assemblies 7 of the 5 groups of equipment are removed from the automatic docking device 4, the capacity reduction is completed, and only 3 groups of equipment are kept running to maintain 300 tons of capacity supply.

Therefore, the protection scope of the present application should be subject to the appended claims.
