Description

Technical Field

[0001] The utility model relates to the technical field of a liquid supply system, in particular to an elevated flow channel liquid supply system for crystalline liquids. Background Art

[0002] At present, neutral liquid and anode liquid are stored in pools. When in use, multiple centrifugal pumps are used to pump the liquid into the elevated flow channel through pipes. Since the elevated flow channel is about 15 meters high, each pump outlet is connected to the elevated flow channel with a pipe. There are many pipes and the site is relatively chaotic. After the valve is closed, liquid stays in the pipe. Since the liquid has crystalline properties, the pipe needs to be removed and cleaned after a period of use, which is very troublesome and labor-intensive for employees. Utility Model Content

[0012] As a further solution of the utility model: the top of the liquid collecting device is connected to a pressure relief pipeline, and a one-way valve is arranged in the pressure relief pipeline to prevent the material in the liquid collecting device from being discharged to the outside.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0019] See also Figures 1 to 3 In an embodiment of the utility model, an elevated flow trough liquid supply system includes a control end, a liquid supply pipe 1 and a plurality of centrifugal pumps 2, the output ends of the centrifugal pumps 2 are respectively connected to the liquid delivery pipes 3, the output ends of the liquid delivery pipes 3 are connected to the liquid separation device 4, the liquid separation device 4 is connected to the liquid collection device 6 through the lifting pipe 5, and the plurality of centrifugal pumps 2 supply the pool liquid into the liquid separation device 4 through the plurality of liquid supply pipes 1;

[0020] The liquid separation device 4 mainly includes a liquid separation cylinder 401, a branch pipe 402 and a main pipe 404. The liquid separation cylinder 401 is connected to a main pipe 404 and multiple branch pipes 402. A main pipe 404 is connected to a lifting pipe 5. The branch pipe 402 is connected to a liquid delivery pipe 3. The liquid is uniformly collected into a main pipe 404 and a lifting pipe 5 through the liquid separation device 4 and transported to a high position. The liquid separation device 4, the liquid collection device 6 and the lifting pipe 5 are made of stainless steel pipes or unrepaired steel plates.

[0021] The liquid separation device 4 and the liquid collection device 6 have the same structure and are used for simultaneously conveying liquid when multiple centrifugal pumps 2 pump liquid. Brackets are welded under the liquid separation device 4 and the liquid collection device 6 to keep the cylinder balanced and stable.

[0022] In a preferred embodiment, one side of the liquid separation cylinder 401 is open to the outside, and a blind plate 405 for maintenance is installed on the open side by bolts so that it can be disassembled. After being used for a period of time, it is disassembled to clean the crystals inside the liquid separation cylinder 401. Only a lifting pipe 5 with a larger diameter is installed between the ground and the elevated flow channel. The installation is simple and convenient, and the appearance is beautiful. It is economical and practical. When cleaning the crystals, only clean water needs to be pumped into the pipe to dissolve them. Cleaning also only needs to clean one pipe, reducing the labor intensity.

[0023] In a preferred embodiment, a flow control valve 403 for controlling the ratio of liquid inlet and outlet is installed on the branch pipe 402, and the branch pipes 402 of the liquid separation device 4 and the liquid collection device 6 are both equipped with flow control valves 403. The flow control valves 403 of the liquid separation device 4 and the liquid collection device 6 can be controlled to provide different amounts of liquid supply and can also send the liquid supply to different pipelines.

[0024] In a preferred embodiment, the liquid separation device 4 also includes a liquid return interface 406, which is connected to the bottom of the liquid separation cylinder 401. The liquid return interface 406 is connected to the liquid supply pipe 1 through the liquid return pipeline 7. An interlock control valve 8 is installed on the liquid return pipeline 7. The interlock control valve 8 is opened when the flow control valve 403 of the liquid collecting device 6 is fully closed, and the interlock control valve 8 is closed when the flow control valve 403 of the liquid collecting device 6 is opened at any time. After the interlock control valve 8 is opened, the liquid in the lifting pipe 5 will flow back to the liquid supply pipe 1 through the liquid return pipeline 7, and flow back to the pool from the inside of the liquid supply pipe 1, so as to avoid water storage in the pipeline after the valve is closed, causing crystallization in the pipeline.

[0025] In a preferred embodiment, the top of the liquid collecting device 6 is connected to the pressure relief line 9, and a one-way valve 10 is provided in the pressure relief line 9 to prevent the material in the liquid collecting device 6 from being discharged outward. When the liquid in the lifting pipe 5 is discharged through the return line 7, negative pressure will be generated in the liquid collecting device 6 and the liquid separation device 4, resulting in drainage difficulties or low efficiency. For this reason, a pressure relief line 9 and a one-way valve 10 are added to the top of the liquid collecting device 6. When draining water, the one-way valve 10 of the pressure relief line 9 takes in air to balance the air pressure inside the pipeline. When supplying liquid, the one-way valve 10 is sealed. A certain amount of gas is stored in the pressure relief line 9, which can be compressed to adapt to pressure changes in the system, such as water hammer.

[0026] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0027] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
