Utility model content
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art, a kind of device being applicable to small-bore feedwater piping inner surface anticorrosion paint squeezing and coating is provided, this apparatus structure is simple, easy to use, efficiency of construction is high, one-off construction length can reach 1 ~ 3km, and construction cost is low, is specially adapted to caliber DN40 ~ DN150 plain cast iron pipe.The utility model device anticorrosive paint squeezing and coating quality is good, and by the small-bore pipeline inwall of the utility model device process, its anticorrosive paint coating is continuous, complete, and coating thickness is even.
To achieve these goals, the technical solution adopted in the utility model is such:
For a device for small-bore water supply steel tube inner surface anticorrosion paint squeezing and coating, comprise and be coated with pipe device, air compressor and air accumulator, air compressor is connected with air accumulator, and air accumulator is connected with water supply steel tube one end to be repaired; Described painting pipe device to be length the be cylinder of 20-30 centimetre, described cylindrical diameter differs 2-3mm with the internal diameter of water supply steel tube to be repaired; Described painting pipe device comprises front painting pipe device and rear painting pipe device, and front painting pipe device is arranged on water supply steel tube inside, and rear painting pipe device is arranged on the steel pipe nozzle of water supply steel tube and air accumulator link.
Preferably, the material selection elastic polyurethane of described painting pipe device, its quality is light, is convenient to compressed air and blows, simultaneously not sticky anticorrosive paint, in order to avoid coating is bonded at the loss being coated with and pipe device causing plugging or coating.
Further, described painting pipe organ pipe head arranges wire line shoe, is convenient to the handling of steel wire rope.
Preferably, oil water separator is set between air compressor and air accumulator, for separating of impurity such as the moisture condensed in compressed air and oil contents, compressed air is purified.
Further, the steel pipe nozzle of water supply steel tube and air accumulator link is provided with feed pipe, feed pipe connects feed bin, is convenient to placement and the injection of anticorrosive paint.
Compared with prior art, the utility model utilizes compressed air promotion painting pipe device to make anticorrosive paint evenly be coated in water supply steel tube inwall, and then make coating spontaneous curing form anticorrosive paint coating by compressed air sharp draft, use the utility model device to solve narrow space in small-bore feedwater piping and be difficult to the problem of paint, by the utility model device, anticorrosive paint process is carried out to small-bore feedwater piping inwall, its coating is continuous, complete, coating thickness is even, and coating squeezing and coating quality is good.The utility model apparatus structure is simple, easy to use, overcome the drawback of traditional construction mode, efficiency of construction is high, one-off construction length can reach 1 ~ 3km, and construction cost is low, is specially adapted to caliber DN40 ~ DN150 plain cast iron pipe, be small-bore pipeline inner wall anti-corrosive construction preferred option, have market popularization value.
