Abstract

The invention discloses a multi-port variable-strength multifunctional swirler and a design method thereof. The swirler comprises a multi-port shell, the multi-port shell is a cylinder of a multi-thread bottom cover with a cone at the upper end and an opening connected with the lower end in a sealed mode, an inner flow pipe communicating with the multi-thread bottom cover is arranged in the multi-port shell, at least one head variable-lift-angle torsion belt is arranged on the outer wall of the inner flow pipe in the axial direction, the upper end of the inner flow pipe is connected with a conical surface flow guide sleeve, a cylinder opening with external threads is formed in the cone at the upper end of the multi-port shell, a second flange plate is in threaded connection with the cylinder opening, a plurality of cylinder inlets and a plurality of tangential swirling inlets are formed in the lower end cylinder wall, and the lower end of the multi-thread bottom cover is in threaded connection with a first flange. According to the multi-port variable-strength multifunctional swirler and the design method thereof, the design is carried out by combining a turbulent flow field rotational flow coherent structure, a rotational flow field generated under the hydraulic conveying working condition is high in strength and good in energy utilization, the long-distance conveying efficiency is improved, the structure is reasonable, the sealing performance is good, dismounting and mounting as well as function switching are convenient and fast, and operation modes are diversified and flexible.

Description

technical field

[0001] The invention belongs to the technical field of vertical pipeline hydraulic transportation, and in particular relates to a multi-functional spinner with multiple ports and variable strength and a design method. Background technique

[0002] Pipeline hydraulic transportation is a transportation method that uses liquid (usually water) as a carrier to transport solid materials through pipelines. It has been widely used in the engineering field for its advantages of no pollution, energy saving, transportation not affected by the weather, and large transportation volume. application. Conventional axial flow is generally used to transport materials in the pipeline hydraulic lifting system, but the material starts slowly and has strong sedimentation during vertical pipeline hydraulic transportation. At the same time, when the concentration is too high, the material may accumulate in the center of the pipeline and cause silting. In order to improve the above ...
