Technical Field
[0001] The utility model relates to the field of pipeline purge devices, in particular to a pipeline purge device for a gas engineering project. Background Art
[0002] The gas engineering pipeline purging device is an important equipment used to remove impurities in the pipeline. It keeps the pipeline clean and unobstructed through high-pressure gas or liquid purging and impact, thereby ensuring the smooth operation and safe use of the pipeline. This device is not only efficient and reliable, but also effectively saves maintenance costs. It is widely used in gas pipeline cleaning work. However, its applicability is limited to the diameter range of the pipeline. It may not be applicable to pipelines that are too long or too thick. When using it, it is necessary to strictly abide by the operating procedures to ensure operational safety.
[0003] At present, gas pipeline cleaning usually relies on high-pressure blowing by air compressors. However, in this process, the strong airflow blown out by high pressure will carry the dirt and debris in the pipeline to the external environment. These blown-out dirt, driven by the high-speed airflow, will be widely spread, causing considerable harm to the surrounding environment, and the impact range is relatively large. Summary of the invention
[0004] Based on this, the purpose of the utility model is to provide a gas engineering pipeline purging device to solve the technical problem that during the purging process, the high-pressure airflow carries the dirt and is sprayed into the outside air, causing the dirt to cause certain harm to the external environment.

[0006] By adopting the above technical solution, the air compressor delivers high-pressure gas to the inside of the clean pipe through the air pipe to perform a purging operation. The high-pressure and high-speed airflow will carry some dirt and blow into the inner side of the fixed sleeve from one side outlet of the clean pipe. Then, the airflow will pass through the through hole at the center of the limit plate and enter the interior of the baffle cover.
[0007] Furthermore, the filter plate and the mounting groove are in a detachable structure, and a guide cavity is formed between the first guide plate and the second guide plate.
[0008] By adopting the above technical solution, the filter plate can be easily installed, disassembled, cleaned and replaced, which not only improves the convenience of maintenance, but also ensures the durability and stability of the filtering effect, thereby extending the service life of the equipment.
[0009] Furthermore, a first flow diverter and a second flow diverter are provided on the inner side of the second flow diverter, and the first flow diverter is fixedly connected to the second flow diverter via a connecting rod.
[0010] By adopting the above technical solution, the first diverter plate and the second diverter plate can effectively divert the passing airflow, reduce the flow rate of the main airflow, make the airflow more stable, and thus improve the efficiency and effect of the purge.
[0011] Furthermore, a diverter cavity is formed between the first diverter plate and the second diverter plate, and a cross section of the diverter cavity is an arc structure.
[0012] By adopting the above technical solution, a buffer area is provided for the diverted airflow, so that the diverted airflow can be temporarily accumulated in the diverter cavity and then flow out smoothly, thereby effectively reducing the impact force and speed of the airflow.
[0013] Furthermore, a plurality of connecting plates are provided on the other side of the fixing sleeve, and the other side of the connecting plates is connected to the cleaning pipe via a flange.

[0016] By adopting the above technical solution, the installation, disassembly and maintenance of the equipment are greatly facilitated, making the operation more convenient and quick when repairs or replacement of parts are needed, thereby improving the efficiency of equipment maintenance.
[0017] Furthermore, the air compressor is connected to the cleaning pipeline through an air pipe, a pressure gauge is provided on one side of the top of the cleaning pipeline, and a blind plate is provided on the other end of the cleaning pipeline.
[0018] By adopting the above technical solution, a stable supply of high-pressure gas is ensured, which is the basis for pipeline purging operations. This connection method is simple and reliable, and can effectively transmit the high-pressure gas generated by the air compressor to the clean pipeline, providing sufficient power for purging.
[0019] In summary, the utility model mainly has the following beneficial effects:
[0020] 1. The utility model uses a cleaning mechanism. When the air compressor is started, it delivers high-pressure gas to the inside of the cleaning pipe, thereby starting the purging operation. This process is intended to remove impurities, dirt or residues in the pipe. The high-pressure and high-speed airflow carries the purged dirt and blows it into the inner side of the fixed sleeve from the outlet on one side of the pipe. The airflow passes through the through hole at the center of the limit plate and enters the interior of the baffle cover. In this process, the airflow is effectively guided and controlled. Subsequently, the airflow is directed to one side of the filter plate. The function of the filter plate is to filter out the dirt purged in the airflow to prevent these pollutants from being discharged into the external environment, thereby improving the environmental protection performance;
[0021] 2. The utility model sets a first diverter plate and a second diverter plate, and the filtered clean airflow enters the guide cavity. Here, the first diverter plate and the second diverter plate on the inner side of the second guide plate play a key role. They separate an airflow and guide this part of the airflow through the inner diverter cavity. The diverted airflow forms an impact in the main airflow. This impact process converts part of the kinetic energy of the high-speed airflow into internal energy, thereby effectively reducing the speed of the airflow, which not only improves the convenience of using the purge device, but also makes the entire purge process more efficient and controllable.
