Description

Technical Field

[0002] In the prior art, powder refers to the form of a collection of solid particles in a discrete state. It also has fluid properties and can flow and fly during transportation. Negative pressure transportation of fine powder refers to the use of negative pressure, that is, the attraction generated by an air compressor or a vacuum pump, to form a stable material film of the powder material in a closed pipeline, thereby achieving continuous and stable transportation.

[0003] However, in the prior art, the powder material is limited by the power of the vacuum pump or compressor during transportation. In actual implementation, the negative pressure transportation distance of fine powder is short, the pipeline diameter required for the transportation process is large, and the power consumption is large. Affected by the air humidity in the pipeline and the temperature difference between the inside and outside of the pipeline, water droplets are easily attached to the inner wall of the conveying pipeline. During the powder transportation process, the powder is easy to adhere to the pipe wall after encountering water. Long-term use will cause the diameter of the conveying pipeline to become smaller and the pipeline is easy to be blocked. At the same time, the suction stability of the vacuum pump or compressor is poor, which affects the powder transportation efficiency. Therefore, improvements are urgently needed.

[0018] The present application provides a fine powder conveying system, which includes a fine powder tank, a powder storage tank, and a conveying mechanism arranged between the fine powder tank and the powder storage tank, wherein the conveying mechanism includes a conveying pipe arranged between the fine powder tank and the powder storage tank, a conveying fan arranged on the conveying pipe, and a monitoring component arranged on the conveying pipe. By arranging a monitoring component on the conveying pipe for monitoring the working environment parameters in the conveying pipe, the monitoring component can integrate the working parameters and powder flow parameters that affect the powder conveying in the conveying pipe into a signal and transmit it to the upper computer, so that the production staff can monitor the working parameters of the conveying pipe in real time. The production staff can judge whether the inside of the pipeline is blocked according to the working parameters in the conveying pipe, and deal with the blockage abnormality in time to avoid the powder adhering to the inner wall of the conveying pipe during the powder conveying process, thereby reducing the working stability of the conveying fan and reducing the restriction of the conveying distance on the powder conveying. The system has the advantages of simple structure, low operating cost, high degree of automation, and easy promotion and implementation.

[0019] During the implementation of this embodiment, the monitoring component 32 includes a pressure sensor, a temperature sensor, a humidity sensor, a flow sensor, and a signal transmission module arranged on the conveying pipe 30. The pressure sensor, the temperature sensor, the humidity sensor, and the flow sensor are all connected to the signal transmission module by signal.

[0022] During the actual implementation process, a knocking hammer is also provided on the outer wall of the conveying pipe.

The production staff can judge whether the inside of the pipeline is blocked according to the working parameters in the conveying pipe, and deal with the blockage abnormality in time to avoid the powder adhering to the inner wall of the conveying pipe during the powder conveying process, thereby reducing the working stability of the conveying fan and reducing the restriction of the conveying distance on the powder conveying.
