The steam generator is characterized in that an evaporating pipe (2) which is coiled spirally and an electric heating pipe (3) are arranged in a tank body (1), the lower end of the evaporating pipe (2) is communicated with a water tank (4), the upper end of the evaporating pipe (2) is communicated with a steam pipe (5), and heat-conducting oil (6) where the electric heating pipe (3) and the evaporating pipe (2) are soaked is contained in the tank body (1). By the adoption of the steam generator, the service life is effectively prolonged, electricity is saved and production cost is reduced.

Description

Steam generator

technical field

The utility model relates to the device that produces steam on a kind of steam crease-eliminating machine, is specifically related to a kind of steam generator.

Background technology

In leather shoes process, cortex vamp easily produces fold, need to carry out smoothing wrinkle processing, and the high-temperature steam of current common employing steam crease-eliminating machine ejection softens smoothing wrinkle processing to cortex vamp, the microscopic folds on leveling vamp and removal vamp.Steam generator is the device that produces steam in steam crease-eliminating machine, and existing steam generator comprises tank body and electrical heating wire, joining water box and steam pipe on tank body, and electrical heating wire produces the water heating in tank body steam and is exported by steam pipe.There is in use following technological deficiency in this steam generator: 1. owing to adopting electrical heating wire directly to heat the water in tank body, it is larger that water tank is transported to the temperature difference between water and the electrical heating wire in tank body, make electrical heating wire loss very fast, General Life is about one month, the service life of steam generator is short, need often to change, impact is normally produced.2. produce in order to meet serialization, require steam generator continuous wave output high-temperature steam, like this, the power of electrical heating wire is just larger, the tank body restriction that is stressed, considers the security of production, excess steam can only be discharged intermittently time in work, unnecessary heat is difficult to store, and causes a large amount of waste of energy.3. in the time that electrical heating wire damages, steam generator is scrapped substantially, maintenance difficult, and steam generator becomes consumable accessory, often changes, and has increased production cost.

Utility model content

In order to overcome short, waste electric energy and the high deficiency of production cost in existing steam generator service life, the utility model provides a kind of steam generator, and this steam generator has effectively improved service life, has saved electric energy, has reduced production cost.

The technical solution of the utility model is: this steam generator comprises tank body, in described tank body, be provided with evaporation tube and the electric heating tube of coiled coil, the lower end of described evaporation tube is communicated with water tank, the upper end of evaporation tube communicates with steam pipe, is loaded with the conduction oil of submergence electric heating tube and evaporation tube in tank body.

Described tank body upper end is provided with tank mouth and upper cover successively, and described electric heating tube runs through upper cover, and one end of electric heating tube is exposed at upper cover outside, and the other end of electric heating tube extend in tank body.

Between described tank mouth and upper cover by flange, bolt and seal red cardboard and be connected.

The utlity model has following beneficial effect: the utility model has avoided water directly to contact with electric heating tube, electric heating tube itself do not exist the temperature difference or the temperature difference less, improve the service life of electric heating tube, the temperature of conduction oil is more stable, conduction oil can play storing heat simultaneously, reduce heat-energy losses, save electric energy, after tested, save electric energy more than 50%, if electric heating tube damages, only need open the upper cover of tank body and change electric heating tube, maintenance and inspection are convenient, reduced production cost.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Shown in Fig. 1～Fig. 3, this steam generator comprises tank body 1, in described tank body 1, be provided with evaporation tube 2 and the electric heating tube 3 of coiled coil, the lower end of described evaporation tube 2 is communicated with water tank 4, the upper end of evaporation tube 2 communicates with steam pipe 5, is loaded with the conduction oil 6 of submergence electric heating tube 3 and evaporation tube 2 in tank body 1.Add man-hour, evaporation tube 2 adopts copper pipe to be coiled to form, and has good heat conductivity, and the liquid level in water tank 4 is within the altitude range of evaporation tube 2, to ensure that water can enter in evaporation tube 2.

Described tank body 1 upper end is provided with tank mouth 7 and upper cover 8 successively, and described electric heating tube 3 runs through upper cover 8, and one end of electric heating tube 3 is exposed at upper cover 8 outsides, and the other end of electric heating tube 3 extend in tank body 1.

Between described tank mouth 7 and upper cover 8 by flange 9, bolt 10 and seal red cardboard 11 and be connected.

In use, steam pipe 5 is communicated with the lower end of injector 12, and injector 12 is connected with fan heater 13 again and controls its work by control cylinder 14, and the conduction oil in tank body 16 is heated to certain temperature by electric heating tube 3, can pass through temperature controller temperature adjustment; Water in water tank 4 enters in evaporation tube 2, and evaporation tube 2 heats by oil bath, and the water in evaporation tube 2 can evenly be rapidly heated to boiling vaporization formation steam, and steam enters injector along steam pipe 5.Fan heater 13 adds hot-air, hot blast is blown under the effect of blower fan 15, utilize control cylinder 14 to control the position of injector 12 inner carriers 16, when control cylinder 14 is during in free state, under the effect of back-moving spring 17, piston 16 is in top position, outlet and the exhaust duct 18 of fan heater 13 are isolated, hot blast all blows out from injector 12 lower ends, because air quantity is greater than the amount of steam, cannot form aerosol.Step on floor push, control cylinder 14 drives piston 16 to be moved downward to the exit position of fan heater 13, now a large amount of hot blasts are discharged by exhaust duct 18, a small amount of hot blast blows out from playpipe 12 lower ends, the spray volume of the Stroke Control hot blast of regulating piston 16, make hot blast rate be less than the amount of steam, spray mist thereby form steam.

The utility model has avoided water directly to contact with electric heating tube 3, electric heating tube 3 itself do not exist the temperature difference or the temperature difference less, the service life of having improved electric heating tube 3, the temperature of conduction oil 6 is more stable, conduction oil 6 can play storing heat simultaneously, has reduced heat-energy losses, has saved electric energy, after tested, save electric energy more than 50%, if electric heating tube 3 damages, only need open upper cover 8 changes electric heating tube 3, maintenance and inspection are convenient, reduced production cost.
