Pressurizing connector for short-distance material conveying

Abstract

The invention provides a pressurizing joint for short-distance material conveying, which comprises a pressurizing pipe, a pressurizing device and connecting flanges, and the connecting flanges are arranged at the two ends of the pressurizing pipe; the pressurizing pipe comprises a pressurizing section and fixing sections arranged at the two ends of the pressurizing section, the free ends of the fixing sections are connected with the connecting flange, and the connecting flange is used for connecting the pressurizing pipe and a conveying pipeline; the inner diameter of the pressurizing section is larger than that of the fixing section; the inner diameter of the fixed section is equal to that of the conveying pipeline; a plurality of pressurizing holes are formed in the pipe wall of the pressurizing section; the pressurizing device is communicated with the pressurizing hole and is used for providing pressurizing pressure for the pressurizing pipe; the included angle between the axis direction of the pressurizing holes and the material conveying direction is 30-60 degrees. The pressurizing joint provided by the invention is simple in structure, convenient to connect and not easy to block, and has a huge advantage of conveniently conveying solid-liquid mixed materials.

Description

technical field [0001] The invention relates to the technical field of material transportation, in particular to a pressurized joint for short-distance material transportation. Background technique [0002] At present, the use of pipelines for material transportation mainly uses a pressure pump at the head end of the pipeline system or a negative pressure pump at the end of the pipeline system to pressurize the transported material, so that the material can move smoothly in the pipeline with a relatively high speed. to complete material delivery. For long-distance transportation, in addition to using high-power pressure pumps or negative pressure pumps, the more commonly used method is to install a relay device in the middle of the pipeline, that is, a relay pump. As a commonly used relay device for material delivery, the relay pump completes the long-distance transportation of the material through the form of series relay. [0003] In the actual use process, in order to e...

Problems solved by technology

As the dredging point is constantly changing, the length of the pipeline also changes accordingly, so that after the mud is discharged from the end of the pipeline, it still has a large amount of energy and an excessively fast flow rate, so that the mud receiving facilities of the mud treatment plant can bear a large impact force , can easily cause damage to the facility

At present, the commonly used method is to install energy dissipation joints at the end to reduce the energy of the mud at the end in the form of head loss. This method causes energy waste of relay pump ships to a certain extent, and also reduces construction efficiency. cause pipe blockage
