At present, six sampling points are arranged in a workshop, and the taken sample is put into a sample tank and is transmitted to a laboratory in a reciprocating manner through a pneumatic sample feeding system. The pneumatic sample feeding system adopts a positive and negative pressure single pipe to utilize wind pressure generated by a vortex pump as power, and under the automatic control of a PLC programmable controller, the positive and negative distribution of air flow is carried out through an air distribution valve, and air pressure difference corresponding to positive pressure or negative pressure is generated before and after a sample tank, so that the sample tank is pushed to run along a seamless pipeline at a high speed in a two-way manner, and the effect of transporting the sample tank is achieved. However, due to the frequent use of the sample pot, when damaged in the chucking system, the test efficiency of the sample is affected, and the process of taking out the sample pot takes a long time.
The sample tank cylinder body is made of 20# steel, and the sealing rings at the two ends are made of high polymer polyethylene, but under long-term conveying, impact and polishing, cracks and fragments appear on the sealing cover and the sliding ring of the sample tank tube body, a system pipeline is clamped, and the pneumatic conveying system cannot be normally used.
The pneumatic sample feeding pipe system adopts a phi 76 x 4mm seamless pipe, the length from six sampling points to a laboratory pipeline is about 100 meters to 200 meters, the pipeline is lifted, lowered and turned, the bending radius of the pipe is about 2.5 meters, straight pipe sections are reserved on two sides so as to facilitate welding, the adjacent pipes are connected in a sleeve connection mode, the pipe opening in the sleeve is processed into a 30-degree chamfer, and the pipe opening is connected with equipment in a flange connection mode. According to past failure handling experience, the canister is often located between the user side and the two optoelectronic devices at the laboratory. The original method adopts phi 6mm wire rods to manually convey the wire rods to a pipeline at a flange of a photoelectric device, and then cuts the pipeline at the position after judging the position of the clamping tank, and takes out the sample tank. If the sample tank cannot be confirmed, the pipeline is cut successively for gradual investigation until the position of the sample tank is confirmed, all cutting parts are welded and reset after the sample tank is taken out, the treatment and recovery process time is long, and an electric welding and angle grinder is adopted in the operation process
The research is carried out on a molten steel sample tank sample feeding system in the steelmaking process.
