Abstract
The utility model relates to a squeezing coating device for a steel pipe inner coating, which is mainly composed of a hollow cylinder, a circular head, a helical blade, a scraping plate, a sealing bell mouth and a sealing head. The main parts of the squeezing coating device for a steel pipe inner coating are stamped into an entirety by elastic materials. Compared with the prior art, the squeezing coating device for a steel pipe inner coating has powerful elbowpassing ability, and can pass through a 90 DEG elbowed pipeline whose bend radius is smaller than 1.5 D; the pipe diameter can be smaller than 25 mm. The squeezing coating device for a steel pipe inner coating has no holiday and has high spreading quality. The squeezing coating device for a steel pipe inner coating can satisfy the requirement of the construction with multiple elbows and long distance. In addition, the head of the squeezing coating device for a steel pipe inner coating can be provided with a scaling brush so that the squeezing coating device for a steel pipe inner coating can be served as a scale breaker or a pipeline cleaner.
Description
The utility model is a kind of steel pipe undercoating squeezing and coating device, and it relates to the improvement on existing apparatus structure and the performance.
What at present mostly used squeezing and coating device was to be assembled by colloid leather cup polyphone during applying coatings in the steel pipeline integral body.There are two problems in this leather cup formula squeezing and coating device: the one, and the squeezing and coating device itself is with bolt 2-3 leather cup to be contacted, owing to be hard connection, entire length is big in addition, causes by the elbow difficulty.Can not solve caliber D less than 25mm, the bending radius of 90 ° of elbows is less than the squeezing and coating requirement of 1.5D pipeline; The 2nd, in promoting the process of squeezing and coating device operation, compressed air have the situation of gas blowby to take place, and coating full level in pipe is reduced and holiday occurs or pipe top coating such as approaches at shortcoming.
The purpose of this utility model is to provide a kind of novel squeezing and coating device at the deficiency of installing above-mentioned two aspects in the past.It is good that it crosses curved ability, can caliber less than 25mm and 90 ° of elbow bending radius less than 1.5D and many continuously curved pipelines in operation, reach the coating effect of uniform.
The purpose of this utility model reaches by following measure, and it is by hollow cylinder, circular head, helical blade, scraper plate, sealing horn mouth and seal first-class the composition.The parts of squeezing and coating device all adopt elastomeric material to create an overall structure.Wherein hollow cylinder is a hollow structure, and an end is stopped up by circular head, and the other end connects with sealing horn mouth and seal head, the helical blade spiral is wound on the outer surface of hollow cylinder, its tail end and scraper plate join, and scraper plate is the disk shape, and it is looped around on the hollow cylinder.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the profile and the longitudinal sectional drawing of squeezing and coating device.
Below with reference to drawings and Examples the utility model is described in further detail.
Shown in Figure 1, the utility model be molded with rubber pattern be an overall structure.Rubber hardness (Shao Shi) is 50-55.The squeezing and coating device is to be made of hollow cylinder 3, circular head 1, helical blade 2, scraper plate 5, sealing horn mouth 6 and seal head 7.Wherein hollow cylinder 3 is a hollow structure, and its external diameter is 2/4 of a caliber, and its end has a mounting hole site by circular head 1 sealing, circular head 1 end place, and a connecting screw 8 is housed.Hollow cylinder 3 other ends connect with sealing horn mouth 6 and seal head 7.The bump count of helical blade 2 is 3.Its spiral is wound on the outer surface of hollow cylinder 3, and tail end and scraper plate 5 join.Its height is 1/6 of a caliber, length be bending radius 1.5D 90 ° of elbow center radians 1/3, pitch is 1/9 of center radian.Scraper plate 5 is looped around on the hollow cylinder 3 for the disk shape.The sheet number is 2, and front scrapping plate to the length of seal head 7 is 1/6 of center radian.In addition, helical blade 2 is trapezoidal with the cross section of scraper plate 5.The external diameter of scraper plate 5 and seal head 7 respectively greater than caliber 1 to 2mm, the wall thickness of hollow cylinder 3 is decided on caliber size and the required operation pressure of squeezing and coating device.Present embodiment is for designing according to caliber size 48-89mm, and the squeezing and coating operation pressure is less than 0.1MPa, and hollow cylinder 3 thickness are 3mm.Thick 1～the 1.5mm in helical blade 2 tops, the thick 3mm in scraper plate 5 tops.
In addition, the mounting hole site of circular head 1 top end is equipped with a connecting screw 8, and it and squeezing and coating device center line coincide, and pad 9 rust cleaning wire wheels 10 and fixing with nut 11 are housed on it.
The course of work of the present utility model is as follows: 1～2Km in the pipeline of and pressure testing good in welding, put into the squeezing and coating device of a band scaling brush 10, and scaling brush 10 is put into pipe certain magnitude of interference.Make the squeezing and coating device produce axial thrust and radial tension when compressed air enters squeezing and coating device hollow cylinder 3, helical blade 2, scraper plate 5 and seal head 7 are fitted with the pipeline inwall.The squeezing and coating device can be removed the floating rust on the pipeline inwall when the pipeline, impurity such as oxide skin, and be transported to squeezing and coating device rear portion by helicla flute 4, because there is scraper plate 5 to stop, can prevent that it from entering in the pipe simultaneously.After rust cleaning finishes, in pipe, put into first, be put into and calculate in advance on the good position, put into second squeezing and coating device at the mouth of pipe then not with the squeezing and coating device plugging device of scaling brush.Add coating between two squeezing and coating devices.After the pressurization, Compressed Gas enters second squeezing and coating device, makes it promote and produce rotation forward.Along with spinning upside down a coating, helicla flute 4 is assigned to equably around the tube wall.
The utility model compared with prior art had strong, suitable little, the no holiday of caliber of curved ability, film quality advantages of higher.
