Transportation pipe capable of guaranteeing smooth transportation of sludge and using method thereof

Abstract

The invention discloses a transportation pipe capable of guaranteeing smooth transportation of sludge and a using method thereof. The transportation pipe comprises a pump pipe and two pressure pipes arranged on the pump pipe, wherein one pressure pipe is a positive pressure pipe; the other pressure pipe is a negative pressure pipe; the two pressure pipes are spirally arranged on the pump pipe in parallel; a plurality of pressurizing openings are formed in the positive pressure pipe; a plurality of pressure reducing openings are formed in the negative pressure pipe; the pressurizing openings and the pressure reducing openings are alternately arranged at intervals in the pump pipe transportation direction; a plurality of permeation holes are formed in the pump pipe corresponding to the pressurizing openings; an exhaust hole is formed in the pump pipe corresponding to the pressure reducing openings; a plurality of pumps are arranged in the positive pressure pipe; each pump contains a lubricant; the pumps release the lubricants into the positive pressure pipe and pressurize the pressurizing openings; and the lubricants are pressed into the pump pipe through the permeation holes so as to act on the contact surface of the pump pipe and the sludge, so that the outer surface of the sludge is dynamically lubricated in real time, the real-time requirement of the dynamically-changed sludge of the pump pipe for the lubricant is met, the lubrication forming time is continuous, and smooth transportation of the sludge is guaranteed.

Description

technical field [0001] The invention relates to the fields of transportation and lubrication, in particular to a transportation pipe for ensuring smooth transportation of sludge and a method for using it. Background technique [0002] The main methods of sludge transportation are pipeline transportation, truck transportation, barge transportation, and combined transportation methods. Sludge pipeline transportation is a common method for sludge treatment plants or long-distance transportation, which is economical, safe and hygienic. Its delivery system can be divided into gravity pipeline and pressure pipeline in two forms. The main design content of the sludge conveying pipeline is to determine its diameter. The pipe diameter of the sludge pipeline is determined according to the sludge of different properties, and according to the conditions such as the amount of sludge conveyed, moisture content, critical flow velocity and water head loss, a reasonable pipe diameter is se...

AI Technical Summary

Problems solved by technology

However, once the pipeline transportation is completed, the location of the transportation is fixed, and the flexibility is poor.

[0004] Pipeline transportation has high requirements on the transport body, and blockage is also very easy to occur during the transport process. The current solution is to beat with a wooden hammer, or reverse the pump to suck the transport body back to the transport point, and then process it Or clean the transportation pipeline, which brings great inconvenience to the transportation process
