[0002] Suction and pressure conveyor, also known as suction and discharge vehicle, is suitable for metallurgy, chemical industry, energy, building materials, coal, mining, terminal transportation and other industries. It is used for the collection, transportation and delivery of nearly 100 kinds of dust and powder materials under various working conditions. It can carry ironmaking, steelmaking, sintering, coking, raw materials, calcium carbide furnace purification and dust removal, gas-fired lime kiln, smelting desiliconization, dephosphorization agent, coke powder, aluminum powder, cement, mineral powder, lime powder, limestone dust removal ash, mixed dust removal ash and other dust materials. Suction and discharge vehicle is a special vehicle for efficient, safe and environmentally friendly bulk material cleaning and transportation.

[0003] The high-speed impact of materials in the ash discharge process of the ordinary ash discharge pipe will cause wear and tear on the pipe, and even breakdown, resulting in material leakage. Frequent maintenance and replacement will have a great impact on the normal operation of the vehicle. There is an urgent need for a special pipe that can effectively reduce maintenance costs and has a service life of more than 800 hours and is stable.

[0004] Therefore, there is an urgent need to design a wear-resistant ash discharge pipe for a suction and discharge vehicle to solve the problem of excessive wear on the inner wall of the pipe caused by the high-speed impact of materials and to quickly replace the entire pipe.

[0010] Specifically, the ceramic particle wear-resistant coating is filled between the external shield and the middle pipe.

[0011] Specifically, the deceleration swivel baffle is arranged inside the middle pipeline, and the position where the deceleration swivel baffle needs to be welded is determined according to the length and diameter of the pipeline.

[0012] The utility model has the following beneficial effects:

[0013] The utility model designs the wear-resistant ash discharge pipe of the suction and discharge vehicle: by changing the peak flow velocity of the material and guiding and controlling the material flow velocity of 40-100 m / s, the flow direction achieves the mutual friction between the materials instead of the original friction between the materials and the pipe wall, thereby eliminating the abnormal loss of the pipe, saving 50 hours of maintenance time each year and reducing maintenance costs by 70%.
