Description
Technical field
The utility model belongs to steel pipe manufacturing industry technical field of electricity, is a kind of purple solid spray equipment of steel pipe that preheats function with induction specifically, preheats online problem before having solved the purple solid spraying of steel pipe in winter.
Background technology
The purple solid spray equipment of existing steel pipe comprises spray booth, purple solid chamber two parts, and 2 spray gun rings are housed in spray booth, and each ring that sprays paint is equipped with 6 spray guns, and totally 12 spray gun, 30 ° of space intervals; 14 ultraviolet lamps are equipped with in purple solid chamber, are 2 circles and distribute; Between spray booth and purple solid chamber, aluminium matter is installed every tabula rasa, steel pipe by time open, steel pipe was closed in the past, guaranteed that avoiding ultraviolet ray before spray painting irradiates.Coating by container for paint through membrane pump, filter, electric heater, proportioning valve, spray gun spraying to steel tube surface, then after ultraviolet lamp irradiates, be cured to steel tube surface and form coating.The subject matter existing:
1, winter, spray painting temperature need be heated to 40-60 ℃ because steel tube surface temperature is low, and purple solid chamber ultraviolet ray irradiation temperature is high, temperature contrast is large, when the body temperature of steel pipe is lower than below-5 ℃ time, can have a strong impact on the spraying effect of steel pipe, there is large stretch of blistering in coating;
2, adopt fuel oil, gas heating equipment investment larger, and can cause the poor spraying effect that directly has influence on of steel tube surface cleannes;
?3, adopt steam tracing or resistance furnace infiltration heating, firing rate is slow, can not meet rhythm of production requirement.
Utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of purple solid spray equipment of steel pipe that preheats function with induction is provided, mainly solve preheat online before the purple solid spraying of steel pipe in winter adopt fuel oil, gas heating equipment investment is large and steel tube surface cleannes are poor affects spraying effect and adopt steam tracing or the problem such as resistance furnace infiltration heating firing rate is slow.
The technical solution of the utility model is: a kind of purple solid spray equipment of steel pipe that preheats function with induction, by rollgang, spray booth and purple solid chamber, formed, in spray booth, establish spray gun ring, on spray gun ring, spray gun is installed, the purple solid indoor ultraviolet lamp of establishing is established aluminium matter every tabula rasa between spray booth and purple solid chamber; Container for paint is connected with membrane pump, filter, electric heater, proportioning valve, spray gun successively by pipeline; Its special character is, before described spray booth, establish intermediate frequency induction heating device, by intermediate frequency power supply, electric capacity, body of heater induction coil, formed, body of heater induction coil and electric capacity form shunt load resonant tank and are connected to intermediate frequency power supply output, body of heater induction coil is installed on first roller-way interval of spray booth entrance rollgang, treats that oiling steel pipe is through body of heater induction coil on-line heating winter.
Compared with the prior art a kind of purple solid spray equipment of steel pipe that preheats function with induction described in the utility model has following good effect: 1, when winter temperature is during lower than-5 ℃, before the purple solid spraying of steel pipe, adopt electrical induction equipment, steel tube surface temperature is improved to 10-15 ℃, guaranteed the spraying effect of steel pipe ultraviolet curing in winter; 2, apparatus structure is simple, small investment, and do not affect steel tube surface cleannes, firing rate is fast simultaneously, can meet rhythm of production requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, rollgang 2, treat that oiling steel pipe 3, intermediate frequency power supply 4, electric capacity 5, body of heater induction coil 6, spray booth 7, spray gun ring 8, spray gun 9, aluminium matter are every tabula rasa 10, purple solid chamber 11, ultraviolet lamp 12, container for paint 13, membrane pump 14, filter 15, electric heater 16, proportioning valve.
The specific embodiment
For Comprehension and Implementation better, below in conjunction with accompanying drawing, provide specific embodiment and describe the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 1, at the interior installation spray gun of spray booth 6 ring 7, spray gun 8 is installed on spray gun ring 7; At the interior installation ultraviolet lamp 11 in the solid chamber 10 of purple; Between spray booth 6 and purple solid chamber 10, aluminium matter is installed every tabula rasa 9; Container for paint 12 is connected with membrane pump 13, filter 14, electric heater 15, proportioning valve 16, spray gun 8 successively by pipeline; At the front installation intermediate frequency induction heating device of spray booth 6, by intermediate frequency power supply 3, electric capacity 4, body of heater induction coil 5, formed, body of heater induction coil 5 forms shunt load resonant tank with electric capacity 4 and is connected to intermediate frequency power supply 3 outputs, body of heater induction coil 5 is installed on first roller-way interval of spray booth 6 entrance rollgangs 1, treats that oiling steel pipe 2 is through body of heater induction coil 5 on-line heatings winter; Intermediate frequency induction heating device, frequency adopts 500-1000HZ, and permeability is better, according to steel pipe specification different choice dimension induction coil, to guarantee heating effect, to reduce energy loss; Maximum specification external diameter Φ, wall thickness δ, the oiling maximal rate S of purple solid oiling steel pipe, can calculate the tube quality M that needs heating per minute as required; When winter temperature is-5 ℃, need to adopt electrical induction equipment, it is 10 ℃ of left and right, △ T=15 ℃ that steel tube surface temperature is brought up to; By formula W=C*M* △ T=P*t* η, iron and steel specific heat C is 0.46kJ/ (kg ℃), and induction heating apparatus efficiency eta gets 65%, calculates the rated power P of the intermediate frequency induction heating device that needs installation.
A kind of purple solid spray equipment of steel pipe that preheats function with induction described in the utility model, winter is when the body temperature of steel pipe is during lower than-5 ℃, because steel tube surface temperature is low, purple solid room temperature is high, and temperature contrast is large, can affect the spraying effect of steel pipe, in this case, open intermediate frequency induction heating device, according to steel pipe specification, adjust heating power setting value, steel tube surface temperature is improved to 10-15 ℃, thereby guaranteed the spraying effect of steel pipe ultraviolet curing in winter.
