Description
Technical field
The present invention relates to a kind of multistation automatic constant-temperature paint finishing, metal conduit securing member guard technology field.
Background technology
The important indicator that the antiseptic property of securing member forms as the offshore oil pipeline system, extensive application is in the oil transportation system and bringing into play vital effect, in case the securing member antiseptic property is not up to standard, the sealing of whole pipeline system also can be affected thereupon, thereby causes possibly the leakage of liquid to cause economic loss without redemption.Along with the development of modern industry, it is more and more important that antiseptic property also becomes, and almost relates to the every field that all concern national economy and people's lives.
Before this, antiseptic and rustproof traditional method for the securing member that uses under the adverse circumstances such as ocean carries out simple surface treatment at fastener surface exactly both at home and abroad, as apply paint, smear antirust oil, oxidation, metallizing coating etc., but the effect of conventional method is so not satisfactory, and present do in Offshore Engineering more is exactly in the situation that product surface is only done bottom or do not had the directly random coating oil lacquer coat of bottom layer treatment or metal coating, but the coating adhesion of paint but is not fine, the appearance surfaces of metal coating is coarse very not attractive in appearance, easily wearing and tearing, damage and cause installing rear antiseptic effect and can have a greatly reduced quality, so along with rugged environment more and more to the raising of the requirement of properties of product, these traditional anticorrosion process just being abandoned by people gradually.
Traditional anticorrosion process is owing to technique and raw material are single, backwardness, the in addition factors such as execute-in-place, so product is after reaching the spot, careless slightly or simply collide with etc., thereby coating just is easy to come off and directly causes the antiseptic property of fastener products greatly to reduce, and because the product antiseptic property reduces, cause the investment risk of engineering project larger.
For the strict conduit fastener of requirement for anticorrosion, usually adopt Teflon coating to carry out protective treatment, because Teflon coating in use has certain temperature requirement, if the coating quality that all may cause too high or too low for temperature is difficult to guarantee its antiseptic property requirement.Traditional spraying protective treatment is carried out in water-screen cabinet, but traditional water-screen cabinet is difficult to again guarantee environment temperature, causes coating quality to be difficult to guarantee.
Summary of the invention
The objective of the invention is, the temperature that exists according to the conventional spray paint protective coating can not guarantee the problem that causes coating quality not high, and the present invention disclose a kind of multistation automatic constant-temperature paint finishing, makes sprayed coating and spraying environment maintenance temperature constant state.
Technical scheme of the present invention is, the coating of spraying and the environment of spraying are adopted respectively the automatic control measure of constant temperature, realizes that constant temperature coating sprays in the environment of constant temperature, guarantees the spray painting quality.
Multistation automatic constant-temperature paint finishing of the present invention is comprised of cascade constant temperature spray equipment, coating thermostatic device, water cooling unit and control system, water cooling unit is connected with inlet/outlet valve on the water tank by water inlet pipe and water outlet pipe, and paint can connects the multistation automatic spray gun by the coating inlet pipeline.Described system comes the operating temperature of adjusting coating according to the coating temperature to the cooling of water to the heating of water or control water cooling unit by control system automatic control electrical heating pipe, make it remain on the temperature range of setting; According to operating ambient temperature, by control system automatically the cold and hot airduct of control make it remain on the operating temperature range of setting to the cascade constant temperature spray equipment size of transporting cold wind or hot blast and air quantity whether.
Cascade constant temperature spray equipment is to improve on the basis of traditional cascade spraying box to form, and it is comprised of water-screen cabinet, multistation automatic spray gun, cascade case temperature sensor, workpiece suspension rod, cold-hot wind spout and coating inlet pipeline.Water-screen cabinet is the water-screen cabinet of a sealing, suspention is set by the workpiece suspension rod of spraying workpiece before the water-screen cabinet cascade, before the multistation automatic spray gun is positioned at the water-screen cabinet workpiece, and multistation automatic spray gun alignment pieces; The water-screen cabinet side is settled cold-hot wind nozzle and cascade case temperature sensor, by the export-oriented cold-hot wind pipeline transporting cold wind of water-screen cabinet or hot blast, send cold wind or hot blast by the cold-hot wind nozzle in cabinet; Temperature controller is arranged in the cabinet, monitoring and automatically regulate in-cabinet temperature, and the size of automatically regulating transporting cold wind whether or hot blast and air quantity satisfies spray equipment to the demand of constant temperature.
Coating thermostatic device is comprised of paint can, water tank, agitator, electric heating tube, temperature controller and coating temperature sensor; Water tank is a closed body structure, water storage in the case, and water tank wall is provided with the Inlet and outlet water valve, and the paint can mouth is installed on the tank lid, and can body is under water; Electric heating tube is arranged on the correct position of close paint can in the water tank, and temperature controller is installed on the cistern cover plate, and the coating temperature sensor inserts in the paint can coating, monitors the coating temperature and temperature signal is reached temperature controller.
Water in the electric heater for heating water tank can make the paint can heating that is immersed in the water, allows the coating temperature in the paint can improve.Because the boiling point of water is 100 ℃, be immersed in that the coating in the paint can not surpass 100 ℃ all the time in the water, can avoid paint can directly to be caused the rotten deficiency of coating hot-spot by electric heater for heating.
Water cooling unit is connected with water tank Inlet and outlet water valve by water inlet pipe and water outlet pipe, when the coating temperature is higher than the temperature of setting, carries cold water and water tank water tank to exchange reduction water tank water temperature thereby start water cooling unit to water tank, and the coating temperature is reduced.
Control system is comprised of temperature controller, temperature sensor and the control circuit with single-chip microcomputer.Electric heating tube and water cooling unit are chain each other, and electric heating tube is cut off in water cooling unit work automatically; Water cooling unit is cut off in electric heating tube work automatically, is controlled by control system.
The present invention's beneficial effect compared with the prior art is, it is 100 ℃ characteristic that the present invention utilizes the boiling point of water, by water the letter of coating is connect heating, adopt temperature control system that the temperature of coating and spraying environment is automatically controlled and regulated, they can be worked in the operating temperature range of setting, owing to having controlled the temperature of coating and the operating ambient temperature of spraying, coating quality improves greatly, and the qualification rate of product also grows steadily.
The present invention is applicable to the protective treatment of conduit fastener.
