Problems solved by technology

[0003] In order to solve the problem that the wet stone powder is easily attached to the pipe wall when it is transported in the pipeline, thereby blocking the pipeline, the present invention provides a flushing method for the powder conveying pipeline. Through the present invention, it is possible to prevent the powder from When there is congestion, it can play a certain role in removing the attachment, so as to avoid the occurrence of pipeline blockage

Embodiment Construction

[0009] At the starting end of the transmission pipeline close to the discharge port of the lime silo, several sections of flushing pipelines are welded. On-off valves are installed on the flushing pipelines and the other end of the flushing pipelines is connected to the flushing gas source. The on-off valves can be solenoid valves or electric valves. figure 1 The arrow in the figure indicates the transportation direction of the powder transported by the transmission pipeline. The opening and closing of the flushing pipeline is controlled by the on-off valve. The flushing pipeline is divided into a main flushing pipeline and an auxiliary flushing pipeline. The installation sequence of the flushing pipeline is as follows: The main pipeline and the transmission pipeline form an angle, which is called the X angle. Starting from the main pipeline for flushing, along the transmission direction of the transmission pipeline, an auxiliary pipeline for flushing is set at a certain distanc...

Abstract

The invention provides a flushing method for a powder conveying pipeline. Wet stone powder is conveyed in the pipeline and is prone to being attached to the pipe wall, and thus the pipeline blocking situation is generated. Through the flushing method, during production, attaching of the powder can be prevented; and during congestion, the effect of removing attachments can be achieved to a certainextent, and thus the pipeline blocking situation is avoided.

Description

technical field [0001] The invention relates to a flushing method of a powder transmission pipeline, which is used for pipeline flushing of stone powder transmission in the glass fiber manufacturing industry. Background technique [0002] In the glass fiber manufacturing industry, the stones mined on the mountain are crushed and turned into powdery substances. These substances are transported to the kiln for high-temperature incineration through some iron or steel pipes under the action of high-pressure air. Melt, and then draw the melted stone powder into glass fiber through some special equipment. In actual operation, the crushed stone powder is not always dry, and a considerable part is wet. The wet stone powder is transported in the pipeline, because the pressure of the high-pressure air source is generally constant pressure, and the stone powder The transmission process will be relatively stable, the pipeline will not vibrate, and the inside of the pipeline is in a rel...
