A multi-functional spinner with variable strength and its design method

Abstract

The invention discloses a multi-functional spinner with variable strength and a design method thereof. The spinner includes a multi-port housing, the upper end of which is provided with a cone, and the lower end is sealed and connected with a multi-threaded opening. In the cylindrical body of the bottom cover, the multi-port housing is provided with an inner flow pipe communicating with the multi-threaded bottom cover, and the outer wall of the inner flow pipe is fixed with at least one twisted belt with a variable lift angle in the axial direction. The upper end of the flow tube is connected with a conical guide sleeve, the upper cone of the multi-port housing is provided with a cylindrical port with external threads, the second flange is threaded on the cylindrical port, and multiple cylindrical inlets are provided on the lower wall and a plurality of tangential spinning inlets; the lower end of the multi-threaded bottom cover is threadedly connected with a first flange. The invention is designed in combination with the swirl pseudo-sequence structure of the turbulent flow field, and the swirl field generated under the hydraulic conveyance working condition has strong strength, good energy utilization and improved long-distance conveyance efficiency. The structure is reasonable, the sealing is good, and the disassembly and function switching are convenient and fast, and the operation methods are diverse 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 ...

Problems solved by technology

However, the applicant conducted numerical calculation research on the 201610212206.X patent, and found that this patent is applied in the field of pneumatic transportation. Due to the difference in physical properties between air flow and water flow, the swirling flow intensity of the blade structure designed by this patent is relatively low in vertical hydraulic transportation. Small, it is difficult to achieve the expected effect on the hydraulic lifting of coarse particles; at the same time, the design content of the patent does not combine the fluid flow characteristics and the quasi-sequential structure of the swirl field, and there are certain defects and deficiencies in the energy utilization degree and swirl effect; in addition The structure of this patent design also has some deficiencies in terms of sealing, rationality, etc. and needs to be improved.
