Description

Technical Field

[0001] The utility model belongs to the technical field of flow velocity measurement, and specifically relates to a coal slurry non-horizontal pipeline flow velocity measurement device. Background Art

[0002] Coal slurry is a slurry made by mixing coal powder and water, usually used for combustion or power generation. By monitoring the flow rate of coal slurry, the flow of coal slurry in the pipeline can be monitored in real time, which helps to monitor and adjust the production process in real time to ensure that the process parameters are within the appropriate range and improve production efficiency and product quality.

[0003] However, when testing coal slurry, the detection device is generally connected to the pipeline for conveying coal slurry to ensure real-time detection. However, when testing coal slurry, since the installation of the pipeline may be in a non-horizontal state, impurities may remain in the coal slurry in the pipeline when it flows through the detection device, thereby affecting the measurement result of the coal slurry. Therefore, the measurement device needs to be cleaned. When cleaning the existing detection device, it is usually disassembled and cleaned after the device is blocked. However, since the coal slurry is usually highly concentrated and viscous, and the conveying pipeline is inclined, the probability of the device being blocked will increase, so the measurement device needs to be frequently disassembled and cleaned. Frequent disassembly and cleaning may cause wear at the connection between the device and the hanging machine, thereby causing leakage of coal slurry, and further causing waste of resources.

[0004] In order to solve the above problems, the present application proposes a device for measuring the flow velocity of a coal slurry in a non-horizontal pipeline. Utility Model Content

[0034] Working principle:

[0035] The staff connects the pipeline for conveying coal slurry to the connecting pipe 1 through the first fixing ring 4, and rotates the bolts and nuts on the rotating ring 3 to allow the rotating ring 3 to rotate. The rotation of the rotating ring 3 can drive the rotation of the fixing block 9 and the fixing plate 14. After the fixing plate 14 is rotated to a suitable position, the staff fixes the fixing plate 14 to nearby objects through the through hole 15 to prevent the connecting pipe 1 from shaking during use. After the device is fixed, the pipeline for conveying coal slurry passes through the connecting pipe 1 so that the coal slurry flows through the flow rate meter 2, so that the flow rate of the coal slurry is detected by the flow rate meter 2. At the same time, impurities may accumulate on the flow rate meter 2 during long-term use, so it is necessary to clean the flow rate meter 2. When cleaning the device 2, the staff can close the pipeline for conveying the coal slurry. After closing, the sealing cover 24 is rotated to allow the liquid outlet 23 to allow the coal slurry inside the pipeline to flow out, thereby avoiding waste of coal slurry. After the liquid outlet 23 is opened, the staff presses through the water inlet pipe 19 to allow the water outlet 21 set on the sealing block 17 to leak out, so that the blocking block 7 no longer closes the water outlet 21. The staff connects the external water pipe to the water inlet pipe 19, and allows clean water to flow into the interior of the connecting pipe 1 through the water outlet 21, so that the garbage inside the connecting pipe 1 is cleaned with clean water, and the impurities after cleaning flow out through the liquid outlet 23, thereby realizing the cleaning of the device, thereby avoiding accumulation of the device affecting its use.
