Background
A magnetic suspension fluid conveying mode is a novel pipeline hydraulic conveying mode which is low in cost, low in energy consumption and environment-friendly, and has various advantages compared with a traditional pipeline conveying mode. The traditional pipeline hydraulic transportation technology mainly comprises a slurry pipeline hydraulic transportation mode and a molding material pipeline hydraulic transportation mode. The hydraulic conveying mode of the slurry pipeline is to mix and convey granular solid substances and liquid media, use a clear water centrifugal pump as conveying power and separate the materials and the conveying media at a destination. The molding material pipeline transportation technology is to compress discrete coal particles into a cylindrical compact body with certain strength and then inject the cylindrical compact body into a pressure transportation pipeline for transportation, and the two transportation modes are typical liquid-solid coupling multiphase flow transportation modes.
There are a number of problems with conventional pipe transport techniques.
1) Bulk materials or profile materials are only acted by fluid in all directions in a pipeline, cannot keep concentric motion in the pipeline in high-speed operation, and serious potential safety hazards such as severe impact or mechanical abrasion between the outer wall of the material and the inner wall of the pipeline can occur.
2) The types of bulk materials or profile materials conveying materials can not react with fluid chemically, and the types of the materials conveyed in the pipeline are single.
3) Bulk materials and profile materials can not be stably suspended in the center of the pipeline during conveying, and huge sliding friction is generated between the bulk materials and the inner wall of the pipeline during operation, so that the energy consumption loss is large in the whole long-distance transportation process.
4) In case of safety problems such as pipeline breakage, water leakage and the like in traditional pipeline hydraulic transportation, emergency braking of materials in a pipeline cannot be realized through flow control of an inlet end position, and the pipeline is complex in maintenance operation.
5) The siltation of the pipe wall of the bulk material is easy to occur during the pipeline transportation, and the pipeline can be blocked after long-time operation, which is not beneficial to the long-distance transportation of the pipeline. A large amount of materials are accumulated to cause that an accumulation body is difficult to clean, and the materials are retained in the pipeline to increase the local loading capacity of the pipeline, so that the deformation and settlement hazard of the pipeline are caused.
6) The material obtained by mechanical pressing has higher density and larger required critical starting flow, so the total power load of the water conveying clear water centrifugal pump station is improved. And most materials can not realize the mechanical pressing process, so that the conveying types of the materials are reduced to a certain extent.
7) The materials are required to be dehydrated when being transported to the destination, so that the conveying cost of the working system is increased.
8) The dynamic water pressure of the conveying pipeline is large, the water head of the piezometer tube at the material feeding port is large, and continuous feeding of materials cannot be realized.
In order to solve the above problems existing in the conventional hydraulic conveying method, the utility model provides a novel concept of the novel columnar utricule hydraulic conveying method which uses the magnetic suspension theory as the basic principle and takes the pressure fluid as the conveying medium.

The utility model discloses a through the cladding of material in the carrier soak, realized the effective migration of moulded coal, coking coal in the pipeline, reduced frictional resistance. The different proportions of the molded coal are adopted, so that the transportation uniformity is realized, the impact of the material on the pipeline is reduced, the pipeline damage is prevented, and the maintenance cost is low. The utility model discloses a pipeline siltation is blocked and reduce the pipeline wearing and tearing scheduling problem though solved to a certain extent. But increases the cost of selecting the section material conveying gradation to a certain extent and also puts special requirements on the transportation form of the material. The utility model discloses a although reduced the impact force of material to the pipeline, still can not fundamentally solve safety problems such as wearing and tearing, mechanical striking and the noise of material and pipeline inner wall. Chinese patent CN102862820 discloses a pipeline hydraulic conveying tool and application thereof. The utility model discloses a better solution traditional water conservancy transport exist carry the transport material scope narrow, poor stability, the resistance is big and serious problems such as pipe wear, proposed around the columniform body inside that contains the material tip installation each other become 120 degrees have a cylindric supporter of universal ball, cylindric supporter and the point-to-point contact of pipe inner wall, this mode can effectively reduce the resistance among the material transportation process.
