Description

Pipeline inner wall processing apparatus

Technical Field

The invention relates to a pipeline inner wall treatment device, in particular to a T-shaped pipe treatment device.

Background

The T-shaped pipe comprises a long arm and a cross arm, wherein the middle part of the cross arm is vertically and integrally fixed with the long arm and is communicated with the long arm. The pipeline is subjected to coating protection treatment before delivery, the outer coating is very simple, but the inner diameter of the pipeline is small and difficult to treat. No matter the inner wall is clean and miscellaneous before the coating, still the coating of coating film liquid, all handle by the manual work, the coating film process can select directly to throw away into the coating film liquid pond with the T-shaped pipe directly, but need additionally set up mechanical equipment like this and salvage, and long-time back of using, the inconvenient regulation and control of coating film liquid concentration, this just leads to wanting to maintain the coating film effect and just must let the coating film liquid keep high concentration, can improve the quantity of coating film liquid like this undoubtedly, the manufacturing cost has been increased, and handle improper when changing the coating film liquid that became invalid in a large number and will cause serious environmental pollution, follow-up administration needs to spend a large amount of resources. When the whole process of manual treatment is needed, a worker manually uses a strip-shaped grinding tool to grind one point of the inner wall to ensure thorough grinding, the worker manually grinds and applies force inconveniently and hardly determines the internal grinding state, and in order to increase the speed, the probability of unqualified grinding inside the pipeline is greatly increased, so that the coating liquid cannot really cover the inner wall of the pipeline during subsequent coating; meanwhile, when subsequent coating protection is carried out, the coating tool can shield the visual field, whether coating liquid is coated or not is difficult to determine in a visual field blind area, coating work needs to be carried out repeatedly for ensuring the effect of coating liquid coating, so that coating materials are wasted, the production cost is increased, the coating liquid is in contact with the coating materials harmful to human bodies for a long time, the health of workers is seriously affected, time and money are required to be paid to medical workers, and the loss is doubled.

On one hand, environmental pollution is caused, on the other hand, the efficiency is low, the physical health of workers is influenced, and in any case, the optimal solution is difficult to obtain.
