Description
Technical field
The present invention relates to the pipeline coating equipment, particularly a kind of equipment for coating inner and outer walls of pipeline.
Background technology
For metallic conduit, because main use is steel pipe or cast iron pipe at present, therefore the easy corrosion in surface so effects on surface is processed before use, that is to say the pipeline surfaces externally and internally is carried out application, take steel pipe as example, at present steel pipe before use more adopts zinc-plated or lining is moulded compound mode and advanced application, adopts galvanized pipe, easily causes the corrosion of coating dissolving damaged after long-term the use, metallic zinc easily causes secondary pollution after entering the liquid of pipeline conveying; Adopt lining to mould compound mode, although the intensity of preferably resolving, the technical problem such as anticorrosive, cost is higher, processing inconvenience.
For addressing the above problem, in the last few years, adopt plastic-blasting, soak the mode of moulding the technology that pipeline carries out application has been obtained using widely, adopt this technology, namely at the plastic powders of the surfaces externally and internally application layer of metal tube, make it form thin layer, thereby in good rigidity, elasticity and the intensity of applied metal pipeline, solved metal tube and held corrosion-prone defective.
Be that 200410003085 patent of invention disclosed " Cast-iron pipe inner surface sprayplastic craft " and application number are in 200410001797 the patent of invention disclosed " plastic-blasting process for cast iron pipe external surface " such as China Patent No., to how the technical scheme of coating metal pipe surfaces externally and internally is introduced respectively, yet above-mentioned two technical schemes all exist defective:
1, in above-mentioned two technical schemes, inner surface adopts the vacuum powder injection process, and outer surface adopts the technique of rotating pipe electrostatic spraying, so the pipeline application need to finish step by step, and process operation is loaded down with trivial details, and production efficiency is low;
2, adopt the rotating pipe electrostatic spraying, easily cause pipe surface coating layer uneven distribution, restive, affect coating quality;
3, implement technique scheme, the effective rate of utilization of the powdery paints of spraying is low, has improved the application running cost.
Summary of the invention
The purpose of this invention is to provide a kind of equipment for coating inner and outer walls of pipeline, it can be simultaneously carries out application to the inside and outside wall of pipeline, enhances productivity.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of equipment for coating inner and outer walls of pipeline, and it comprises stock shelf, hot gas source, cartridge heater, curing heat-preservation cylinder, drives a vehicle and is located at the fluidizer between cartridge heater and the curing heat-preservation cylinder; Described fluidizer comprises fluidisation cylinder and the source of the gas that is connected with fluidisation cylinder lower end; Fluidisation cylinder lower end is provided with air inlet, and air inlet and source of the gas are connected; The air inlet top is provided with ventilating board, has a plurality of holes on the ventilating board; Cartridge heater top is provided with hot-wind inlet, and hot-wind inlet and hot gas source are connected; The cartridge heater lower end is provided with air outlet and air-introduced machine, and air outlet and air-introduced machine are connected, and air-introduced machine and hot gas source are connected; Also be provided with the loose solar or lunar halo that is fixedly connected with the cartridge heater inwall in the cartridge heater, loose solar or lunar halo is longitudinally formed by many steel bars, is installed with air-ducting ring on the loose solar or lunar halo, has a plurality of air-guiding holes on the air-ducting ring.
As of the present invention preferred, solidify heat-preservation cylinder consistent with the cartridge heater structure.
As of the present invention preferred, described cartridge heater, curing heat-preservation cylinder are embedded under the workbench, and both expose workbench by the mouth of pipe.
As of the present invention preferred, described fluidisation cylinder is embedded under the workbench, and its mouth of pipe exposes workbench.
In sum, the present invention has following beneficial effect: when carrying out application, utilize driving to hang oneself from stock shelf and get pipeline to be processed, and keep hanging the posture of getting and sink to cartridge heater pipeline is heated, to be heated complete after, still use slings pipeline and sink to the fluidisation cylinder of driving, make the powdery paints in the fluidisation cylinder adhere to inner and outer walls of pipeline, the pipeline of again slinging afterwards sinks to the curing heat-preservation cylinder, after curing a period of time, again takes out cooling and rolls off the production line, encapsulates; By above-mentioned coating process as seen, this equipment can disposablely soak moulds the application of finishing inner and outer walls of pipeline, is convenient to extensive streamlined production, enhances productivity; And because the setting of loose solar or lunar halo and air-ducting ring makes pipeline homogeneous heating everywhere, after pipeline sinks to the fluidisation cylinder, can guarantee that the inner and outer walls of pipeline coating is even, the utilization rate of Effective Raise powdery paints reduces production costs.
