Description
Technical Field
[0001] The invention relates to the technical field of fluid material transportation, in particular to a coaxial transportation device. Background Art
[0002] The pumps widely used in traditional fluid conveying machinery include centrifugal pumps, reciprocating pumps, centrifugal fans, centrifugal blowers, etc. The production of these fluid conveying machinery has long entered the stage of mass quantification and standardization, and the technical support and after-sales maintenance services are very mature. However, in actual situations, the requirements for fluid transportation are gradually increasing. In many occasions, fluid conveying machinery is required to be able to withstand high strength and corrosion resistance. There are also many complex pipeline transportation occasions. In these occasions, traditional fluid conveying machinery becomes very limited. The main problems faced include fluid leakage, impeller corrosion and insufficient head. Therefore, it is particularly important to design a fluid conveying machinery with no impeller contact and good sealing. Summary of the invention
[0003] In view of the deficiencies of the prior art, the present invention provides a coaxial conveying device, which solves the problem that the impeller of the existing fluid conveying machinery is prone to corrosion and leakage.
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a coaxial conveying device, including a main pipeline, characterized in that an active side inlet pipeline and a driven side inlet pipeline are respectively provided at both ends of the main pipeline, an active side outlet pipeline and a driven side outlet pipeline are provided on the side wall of the main pipeline, an active side bracket of a synchronous shaft and a driven side bracket of a synchronous shaft are installed inside the main pipeline, a master-slave synchronous rotating shaft is rotatably installed on the active side bracket of the synchronous shaft and the driven side bracket of the synchronous shaft, and an active side propeller blade and a driven side spiral auger are respectively installed on the master-slave synchronous rotating shaft.
[0005] Preferably, a master-slave partition plate is provided in the main pipeline and between the active side outlet pipeline and the driven side outlet pipeline, and an active side outlet fluid guide plate and a driven side outlet fluid guide plate are respectively provided on both sides of the master-slave partition plate and on the inner wall of the main pipeline, and the master-slave synchronous rotating shaft is rotatably installed in the master-slave partition plate.
[0006] Preferably, the active side inlet pipe is connected to the active side outlet pipe, the driven side inlet pipe is connected to the driven side outlet pipe.
[0007] Preferably, the active side outlet pipe and the driven side outlet pipe are located on the same side of the main pipe.
[0008] Beneficial Effects
[0009] The present invention provides a coaxial conveying device, which has the following beneficial effects:
[0010] 1. A main pipeline is divided into an active side and a driven side. The active side has propeller blades and the driven side has a spiral auger, and the two are installed on the same rotating shaft. The fluid that provides power enters from the fluid inlet of the active side and flows out from the fluid outlet of the active side. The coaxially installed propeller blades and spiral auger, when the fluid flowing through the active side drives the propeller blades to rotate, synchronously drives the auger on the driven side to rotate. The rotating spiral auger generates axial thrust, sucks the material fluid from the driven inlet and pushes it to the driven outlet to realize material fluid transportation. The advantage of this design is that the power of the active side fluid is used to drive the transportation of the driven side material. The traditional pump body impeller only contacts with the safe and non-corrosive liquid on the active side. The flow selectivity that can be transported on the driven side is more, avoiding corrosion of the pump body impeller. The fluids on the active and driven sides are only transmitted through the main pipeline. The structure is simple and effective, reducing the risk of leakage. BRIEF DESCRIPTION OF THE DRAWINGS
