Description

Technical Field

[0001] This utility model belongs to the field of slurry pipeline safety protection technology, specifically relating to a combined training device for pressurized leak sealing of slurry pipelines. Background Technology

[0002] In mining, chemical, and energy sectors, slurry pipelines are prone to leaks due to wear and tear, as well as third-party damage such as mechanical excavation and geological disasters. Slurries and muds, for example, are characterized by high concentrations and corrosiveness; if leaks are not handled promptly, they can lead to environmental pollution, equipment damage, or even safety accidents.

[0003] To improve the ability of staff to respond to emergency situations, various simulation training exercises are necessary, with leak sealing training being a crucial component. Leak sealing refers to the sealing measures taken in response to leaks in storage tanks, pipelines, and other similar facilities. Currently, practical training for pressurized leak sealing in slurry pipelines faces the following problems: First, existing training devices mostly use pipes of fixed specifications, failing to simulate leak scenarios involving multiple pipe sizes; second, the lack of realistic pressurized environment simulation makes it difficult for trainees to grasp leak scenarios under dynamic pressure, thus hindering their mastery of leak sealing techniques under pressure; third, the devices are limited in function and cannot combine multiple leak types (such as cracks, holes, and joint leaks), resulting in insufficient training relevance. Therefore, there is an urgent need to design an adjustable, multi-functional pressurized leak sealing combined training device to enhance emergency response capabilities and achieve the training objective of "close to real combat and rapid response." Utility Model Content

[0004] The purpose of this invention is to provide a combined training device for live leak sealing in slurry pipelines, which solves the problems of existing training devices being unable to simulate leakage scenarios of pipelines of various specifications, lacking realistic live pressure environment simulation, and having limited functionality and being unable to combine multiple leakage forms.

[0005] The technical solution adopted in this utility model is a combined training device for pressurized plugging of slurry pipelines, including a slurry storage tank. The slurry storage tank is connected to a centrifugal pump through a first pipe. The outlet end of the centrifugal pump is connected to a leakage simulation unit through a second pipe. The leakage simulation unit is connected to a waste slurry tank through a third pipe. A submersible pump is installed in the waste slurry tank. The outlet end of the submersible pump is connected to the slurry storage tank through a fourth pipe. An overflow weir is provided around the leakage simulation unit. A guide channel is provided at the bottom of the overflow weir. The other end of the guide channel is connected to the waste slurry tank.

[0006] The features of this utility model also include: The slurry storage tank is equipped with an agitator, which is connected to a controller via a wire.

[0007] A pressure regulating valve and a pressure gauge are installed on the third pipeline, with the pressure gauge located between the leakage simulation unit and the pressure regulating valve.

[0008] The leakage simulation unit is equipped with a protective railing on the outside.

[0009] The leakage simulation unit includes a leakage simulation support, on which a leakage simulation pipe is fixed. The input end of the leakage simulation pipe is connected to a second pipe, and the output end of the leakage simulation pipe is connected to a third pipe.

[0010] The leakage simulation support consists of two support units, which are symmetrically arranged, and the leakage simulation pipeline is fixed to the two support units.

[0011] The support unit includes a support base, on which a first column and a second column are vertically fixed. A first crossbeam, a second crossbeam, and a third crossbeam are horizontally fixed between the first column and the second column from low to high. The distance between the first crossbeam and the second crossbeam is not less than 600cm, and the distance between the second crossbeam and the third crossbeam is not less than 500cm.

[0012] The leakage simulation pipeline includes a first simulation pipeline, a second simulation pipeline, and a third simulation pipeline. The first simulation pipeline is fixed to the first crossbeam by a first U-shaped pipe clamp, the second simulation pipeline is fixed to the second crossbeam by a second U-shaped pipe clamp, and the third simulation pipeline is fixed to the third crossbeam by a third U-shaped pipe clamp.

[0013] The beneficial effects of this utility model are: The slurry pipeline pressurized leak sealing combined training device provided by this utility model can quickly switch between training scenarios with multiple pipe diameters such as 200mm, 400mm and 610mm by replacing the leak simulation unit and adjusting the crossbeam spacing. The device is equipped with a pressurized circulation system, which can realize pressure regulation and medium flow from 0.1 to 0.8MPa. In combination with different leakage forms, it can realistically simulate working conditions, improve trainees' ability to master dynamic leaks, and thus improve emergency response capabilities. It adopts a layered support structure, which is stable and reliable. The guardrail and flexible connection design ensure training safety, and each component is detachable, which is convenient for maintenance and scenario expansion. Attached Figure Description
