Description

Injection apparatus that clearance was used is remained to nodular cast-iron pipe psammitolite Technical Field The invention mainly relates to the technical field of pipeline jet cleaning, in particular to a jet device for cleaning sand core residues of a nodular cast iron pipe. Background In the centrifugal casting process of the spheroidal graphite cast iron pipe, a pipe casting machine forms high-temperature molten iron (more than or equal to 1350 ℃) into a pipe body through high-speed rotation. In order to prevent the leakage of molten iron from the nozzle, a sand core is required to be installed at the pipe end as a temporary sealing structure. After molten iron is solidified and formed in a pipe die through centrifugal rotation, the spheroidal graphite cast iron pipe can be pulled out by a pipe pulling mechanism, and in the pulling process, the sand core is broken by expansion of a pipe pulling head tensioning mechanism, at the moment, most of the broken sand core can fall into a ground broken core collecting hopper, however, due to high-temperature sintering and mechanical embedding effect, part of sand core residues (mainly a composite body of silica sand and a resin binder) can be closely adhered to the inner wall of a pipe orifice. Because the ductile cast iron pipe needs to be immediately transferred into the annealing furnace for heat treatment after being formed, if sand core residues are not thoroughly removed, the ductile cast iron pipe is melted and sintered in the annealing furnace or falls into the annealing furnace. Thousands of cast iron pipes are processed by the annealing furnace in each shift, a large amount of piled matters are formed after a small amount of broken cores falling from each cast iron pipe are accumulated, the operation of a chain mechanism in the furnace is influenced, and serious safety accidents can occur due to the fact that the cast iron pipes deviate in the furnace and even collide with walls in serious cases. The sand core falling in the hearth is cleaned, and then the furnace is stopped, and after a plurality of shifts of forced ventilation and cooling for a long time, the personnel can enter the hearth for operation. Resulting in long downtime. And the sand particles adhered to the inner wall of the cast tube after the cast tube is annealed at high temperature by the annealing furnace are adhered to the inner wall of the cast tube, so that the quality of the cast tube is affected, the cast tube is manually polished in the later period, the labor intensity of workers is increased, and the production efficiency is reduced. During operation of the specific examples, the applicant found the following drawbacks: The existing main stream adopts an artificial pneumatic hammer knocking method to remove sand core residues, the surface temperature of a cast tube after demoulding is extremely high, workers can easily burn due to splashed hot sand grains and tube body heat radiation if knocking is carried out for a long time at a short distance, residual dead angles are difficult to eradicate, embedded residues in a tube orifice reducing area and a flange groove are low in clearance rate, the embedded residues are basically ineffective to phenolic resin bonded sand permeated into micropores of a tube wall, dust generated by hammering is diffused in a workshop, and the workers need to wear heavy protective equipment for operation in working, so that the working efficiency is low. The above-described contents are within the technical knowledge of the skilled person, and the contents of the present application are not necessarily the prior art because the contents of the present application are huge and complicated.
