Material conveying pipe

Abstract

The invention relates to a solid material conveying pipeline, and in particular relates to a conveying pipeline capable of preventing materials from blocking. The material conveying pipe provided by the invention comprises an external pipe; one end of the external pipe is a feeding port; the other end of the external pipe is a discharging port; the upper pipe wall in the external pipe is fixedly fitted with an internal pipe; a material channel is formed between the external wall of the internal pipe and the internal wall of the external pipe; a plurality of flowing-aided through holes distributed along the length direction of the internal pipe are formed on the pipe wall of the internal pipe towards the material channel; and a flowing-aided plate passing through the flowing-aided through holes and stretching in the material channel is extended downwards from the upper pipe wall in the internal pipe. As the flowing-aided through holes and the flowing-aided plate are adopted, the material conveying pipe provided by the invention can effectively prevent blocking.

Description

technical field [0001] The invention relates to a conveying pipeline for solid materials, in particular to a conveying pipeline capable of preventing material clogging. Background technique [0002] A major problem in the transportation of solid materials is that some solid materials are easy to bond with moisture in the air, thus depositing on the pipeline during the transportation process, causing pipeline blockage. For example, the sintered ash powder of a steel plant is generally a white powder material, which is mainly obtained by the following chemical reaction when limestone (CaCO3) is calcined: [0003] [0004] Therefore, the main component of the white powdery material is CaO, its chemical properties are very unstable, and the following chemical reactions will occur when exposed to the air: [0005] [0006] During the transportation process, the compressed air for transportation is fully mixed with the white powdery material, which is more likely to promote...

Problems solved by technology

However, the problem is that for some materials with a high flow rate, deposition and blockage often occur instantaneously. When the material is deposited and accumulated rapidly, the flow channel of the compressed air is rapidly reduced or even completely blocked. At this time , the compressed air has no way to go, cannot flow to the deflector, and cannot change the flow direction through the deflector, and cannot play the role of anti-blocking

However, the flow-aiding device still has the following problems: first, the molding process is relatively complicated, because holes need to be opened on the pipeline, and each hole must correspond to a flow-aiding branch pipe, although the process of opening the holes is not difficult, but, Each hole must be sealed with the flow-aid branch pipe, which increases the difficulty of the process; at the same time, each flow-aid branch pipe is connected with the flow-aid pipe, and the flow-aid branch pipe and the flow-aid pipe also need to be sealed. Further increase the difficulty of the process

Second, the flow aid device adopts multiple flow aid tubes and flow aid branch pipes, and the flow aid device also needs to be provided with an air source supply device. All the flow aid tubes, flow aid branch tubes and air source supply devices are arranged The outside of the road has a complex structure. When used, this complex structure requires a large installation space, which is not suitable for a small installation space and has poor versatility.

Third, the conveying pipeline has a plurality of flow-aiding branch pipes, flow-aiding pipes and other devices arranged outside the conveying pipeline, and each flow-aiding pipe and its corresponding flow-aiding branch pipes are responsible for a Part of the air source is provided. Once the flow aid pipe or the flow aid branch pipe is damaged or leaks, it will not be able to prevent the blockage of this part. In severe cases, it will lead to blockage of the entire pipeline. Therefore, the flow aid device needs Carry out good maintenance on the flow aid branch pipe and the flow aid pipe, which undoubtedly increases the difficulty of maintenance work
