Description

Technical Field

[0001] This utility model relates to the field of slurry sampling pipeline technology, and more specifically, to a slurry sampling pipeline device with a backwashing structure. Background Technology

[0002] The density of limestone slurry in the absorber of an aluminum electrolytic desulfurization system is a crucial parameter in the desulfurization process, and its accuracy is essential for operators to make process adjustments. Typically, the absorber slurry density is measured by comparing a pressure transmitter with manual sampling to ensure accuracy. However, manual sampling pipelines can sometimes become clogged due to slurry sedimentation, preventing sampling or resulting in inaccurate results. Therefore, flushing the sampling pipelines is necessary to ensure the accuracy of the sampling results.

[0003] Most existing slurry sampling pipeline devices lack thorough flushing, a stable and efficient flushing structure, and protection against water flow impact during flushing. The overall durability and practicality of the pipeline need improvement. For example, invention patent CN111103165A discloses a pipeline sample sampling and backflushing device, which includes: a sample sampling inlet and an outer sleeve outlet on a cylinder; a two-position three-way valve installed on the outer sleeve outlet via an adapter, the adapter having a passage connecting the outer sleeve outlet and the two-position three-way valve; an inner sleeve installed inside the cylinder, the inner sleeve communicating with the sample sampling inlet; an outer sleeve slidably fitted onto the inner sleeve, the outer sleeve extending beyond the outer sleeve outlet; and a sampling nozzle installed at the upper end of the outer sleeve. However, this device lacks a stable and efficient flushing structure and protection against water flow impact. Utility Model Content

[0030] This embodiment connects the slurry sampling pipeline device to the absorption tower of the aluminum electrolytic desulfurization system. Sampling can be completed by opening the sampling valve. Simultaneously, a backwashing pipeline is installed on the sampling pipe, allowing for external flushing water to rinse the pipe. A sealing valve is installed at the sampling pipe outlet, which can be opened to close the outlet and prevent flushing water from escaping. After rinsing, slurry residue on the inner wall of the sampling pipe is removed, ensuring proper slurry sampling, improving sampling accuracy, and providing convenience for sampling personnel. The specific implementation method is as follows:

[0031] like Figures 1 to 4As shown, a slurry sampling pipeline device with a backwashing structure includes a sampling pipe 2, a sampling valve 3, a shut-off valve 4, and a backwashing pipeline 5. The sampling valve 3 and the shut-off valve 4 are respectively installed on the pipe wall at the inlet and outlet of the sampling pipe 2. The inlet end of the sampling pipe 2 is connected to the absorption tower 1 of the aluminum electrolytic desulfurization system, and the middle part of the sampling pipe 2 is connected to the backwashing pipeline 5, which is connected to an external flushing water source. By connecting the slurry sampling pipeline device to the absorption tower of the aluminum electrolytic desulfurization system, sampling can be completed by opening the sampling valve 3. At the same time, the backwashing pipeline 5 on the sampling pipe 2 allows for external flushing water to be connected to flush the sampling pipe 2. The shut-off valve 4 at the outlet of the sampling pipe 2 can be opened to close the outlet of the sampling pipe 2, preventing flushing water from being discharged from the outlet of the sampling pipe 2. After the sampling pipe 2 is flushed, the slurry residue on the inner wall of the sampling pipe 2 can be removed, ensuring normal slurry sampling, improving sampling accuracy, and bringing convenience to the sampling staff.

[0032] A flushing valve 7 and a booster pump 8 are installed on the backwashing pipe 5. The booster pump 8 installed on the backwashing pipe 5 can increase the flow rate of the flushing water and improve the flushing efficiency. The flushing valve 7 is the control valve of the backwashing pipe 5.

[0033] An auxiliary flushing pipe 6 is installed on the sampling tube 2 next to the backwash pipe 5, and an auxiliary valve 13 is installed on the auxiliary flushing pipe 6. By providing an additional flushing water flow during the backwashing process of the backwash pipe 5, the sampling tube 2 can be flushed more thoroughly, thus improving the flushing effect. At the same time, the auxiliary flushing pipe 6 can also be used as a backup flushing pipe.

[0034] A manual valve 10 is installed on the sampling tube 2 next to the sampling valve 3. The flow of the sampling tube 2 can be manually controlled by the manual valve 10.

[0035] The sampling tube 2 is equipped with a pressure-bearing sleeve 16 inside, and a wear-resistant inner tube 17 is installed on the inner wall of the sampling tube 2. The pressure-bearing sleeve 16 installed inside the sampling tube 2 can improve the strength of the sampling tube 2 and enhance its pressure resistance, making it less prone to damage. The wear-resistant inner tube 17 installed on the inner wall of the sampling tube 2 can enhance the wear resistance of the pipeline and increase its service life.

[0036] A monitoring box 11 is installed in the middle of the sampling tube 2, whose inner and outer surfaces are coated with corrosion-resistant coatings. The monitoring box 11 is equipped with a pressure monitoring component, which includes a pressure detector 15 and an alarm 14. The pressure detector 15 is installed inside the monitoring box 11, with its detection end located on the inner wall of the sampling tube 2. The alarm 14 is installed on the top of the monitoring box 11. Through the monitoring box 11 installed on the sampling tube 2, the pressure in the pipeline can be detected by the pressure monitoring component, and the pressure detector 15 can monitor the internal pressure of the pipeline. In case of abnormal pressure, the alarm 14 can sound an alarm to promptly alert personnel to take appropriate action.

[0037] A pressure display 12 is installed on the front of the monitoring box 11. Both the pressure display 12 and the alarm 14 are electrically connected to the pressure detector 15. The pressure display 12 can show the specific pressure of the pressure detector 15, which is convenient for staff to check. The specific model of the pressure detector 15 is K0601.

[0038] Both the backwash pipe 5 and the auxiliary flush pipe 6 are equipped with flushing connectors 9 at their inlets. The flushing connectors 9 allow staff to easily connect the backwash pipe 5 and the auxiliary flush pipe 6 to an external water source.

[0039] Both the inner and outer surfaces of sampling tube 2 are coated with a corrosion-resistant coating. This coating improves the corrosion resistance of the pipe, thereby extending its service life.

[0040] A connecting flange 18 is provided at the connection between the backwash pipe 5 and the absorption tower 1, and a sealing gasket 19 is provided on the connecting flange 18. The connecting flange 18 facilitates the connection between the backwash pipe 5 and the absorption tower 1, and the sealing gasket 19 improves the sealing performance of the pipe connection and prevents leakage of slurry or flushing water.

[0041] Working Principle: The slurry sampling pipeline device is connected to the absorption tower of the aluminum electrolytic desulfurization system. Sampling can be completed by opening the sampling valve. Simultaneously, a backwashing pipeline is installed on the sampling pipe, allowing for external flushing water to rinse the sampling pipe. A sealing valve is installed at the sampling pipe outlet; opening the valve will close the outlet, preventing flushing water from escaping. After flushing, slurry residue on the inner wall of the sampling pipe is removed, ensuring proper slurry sampling, improving sampling accuracy, and facilitating sampling for staff. The booster pump on the pipeline can increase the flow rate of the flushing water and improve the flushing efficiency. The auxiliary flushing pipeline installed next to the backflushing pipeline can provide additional flushing water flow during the backflushing process, thereby improving the flushing degree of the sampling tube and the flushing effect. At the same time, the auxiliary flushing pipeline can also be used as a backup flushing pipeline. The pressure-bearing sleeve installed inside the sampling tube can improve the strength of the sampling tube and enhance its pressure resistance, making it less prone to damage. The wear-resistant inner tube installed on the inner wall of the sampling tube can enhance the wear resistance of the pipeline and increase its service life.

Various modifications and variations can be made to this utility model by those skilled in the art.
