Magnetic suspension fluid conveying device

Abstract

The invention discloses a magnetic suspension fluid conveying device. An open water tank serves as a throwing device of a columnar bag body, fluid serves as a power source of a whole pipeline conveying system, electrified annular solenoid coils symmetrically arranged on the outer wall of a pipeline at intervals generate a constant magnetic field, and a permanent magnet in the columnar bag body serves as a suspension device of the system. Due to the application of the device, the columnar bag body can suspend in the center of the pipeline all the time and can keep stable operation. The long-distance conveying circular pipeline is a guiding device of the system, and a magnetic suspension fluid conveying manner is formed. According to the device, high-speed migration of the columnar bag bodyin the pipeline is more stable and reliable, the height of a pipeline pressure water head at the starting end position is reduced, the operation energy consumption of a working system is reduced, theconveying range of material types is widened, and low-cost, high-efficiency and environment-friendly long-distance transportation of the columnar bag body in the pipeline is achieved.

Description

technical field [0001] The invention relates to the field of energy transmission, in particular to a magnetic levitation fluid transmission device. Background technique [0002] A magnetic levitation fluid transportation method is a new pipeline hydraulic transportation method with low cost, low energy consumption, and environmental protection. Compared with the traditional pipeline transportation method, it has many advantages. The traditional pipeline hydraulic transportation technology mainly includes the slurry pipeline hydraulic transportation method and the molding material pipeline hydraulic transportation method. The slurry pipeline hydraulic transportation method is to mix the granular solid material with the liquid medium and then transport it. The clean water centrifugal pump is used as the transportation power, and the material is separated from the transportation medium at the destination. The molding material pipeline transportation technology is to compress t...

AI Technical Summary

Problems solved by technology

[0004] 1) The bulk material or molded material is only subjected to the force of the fluid in all directions in the pipeline, and cannot maintain concentric movement inside the pipeline during high-speed operation, and there will be serious safety hazards such as violent collision between the outer wall of the material and the inner wall of the pipeline or mechanical wear.

[0005] 2) The type of bulk material or molded material conveyed cannot chemically react with the fluid, and the type of material conveyed in the pipeline is relatively single

[0006] 3) The bulk material and molded material cannot be stably suspended in the center of the pipeline during transportation, and there will be huge sliding friction with the inner wall of the pipeline during operation, resulting in a large energy loss during the entire long-distance transportation process

[0007] 4) In case of safety problems such as pipeline breakage and water leakage in traditional pipeline hydraulic transportation, the emergency braking of materials in the pipeline cannot be realized through the flow control at the inlet end position, and the maintenance operation of the pipeline is relatively complicated

[0008] 5) Bulk materials are prone to siltation on the pipe wall during pipeline transportation, and long-term operation will cause pipeline blockage, which is not conducive to long-distance pipeline transportation

A large amount of material accumulation makes it difficult to clean up the accumulation, and the material stays in the pipeline increases the local load of the pipeline, causing deformation and settlement hazards of the pipeline

[0009] 6) For the molded material obtained by mechanical pressing, due to the high density of the material, the required critical starting flow rate is relatively large, which will increase the total power load of the water delivery centrifugal pumping station

Moreover, most materials cannot be mechanically pressed, which reduces the types of materials to be transported to a certain extent.

[0010] 7) The material needs to be dehydrated when it is transported to the destination, which increases the transportation cost of the working system

The installation of the support body reduces the contact area between the material and the pipe, but the material of the universal ball at the end of the support body is cast iron, which will rust if soaked in the fluid for a long time, so that the support body and the inner wall of the pipe change from rolling contact to Sliding contact, the resistance to carrier migration is still relatively large, which will reduce the operating efficiency of the carrier in the pipeline
