Description

Hot-air circulation type electric oven for shoe-making

Technical field

The utility model relates to a kind of oven dry thermal finalization special equipment of making leather shoes, the hot-air circulation type electric oven for shoe-making that particularly a kind of drying effect is good, safe in utilization, the thermal efficiency is high.

Background technology

The drying box that existing shoe-making industry is used adopts the closed box that has heat-insulation layer mostly, in the left and right side bottom and the bottom of casing electrothermal tube is set, and mainly relies on thermal-radiating mode that the footwear in the casing are carried out drying.Therefore, in dry run, casing is near two side lower parts at electrothermal tube place and the temperature height of bottom, the temperature at other position is low relatively, causes the non-uniform temperature in the casing, thereby the degree of drying of footwear is differed, can produce and do saturating or not burned quality problems, increase percent defective, reduced product percent of pass, improved production cost.Place the electrothermal tube in the casing to utilize bottom and the bottom of binding post non-packed at casing both sides metallic plate, this not only damages electrothermal tube easily, and does not note slightly connecting electricity, and electric shock accidents easily takes place.In addition, the adhesives of footwear and moisture, imflammable gas in the footwear leather material that gasoline soaked discharge under the effect of electrothermal tube in the casing, along with the thermal current of the self-loopa in the case moves.Because row's temperature control that the humidity discharging mouth of casing top is set by temperature controller, so the thermal current that contains moisture, imflammable gas in casing reaches finite concentration and pressure, but the humidity discharging mouth can not discharge during also not to row's temperature of setting, will blast, and brings hidden danger.

When a large amount of production footwear, in order to finish the oven dry task of footwear, the use conveyor type continuous drier that also has rapidly continuously.As disclosing a kind of " using ultrared Device for drying shoes " in the Chinese patent 02806793.It uses near infrared ray, therefore can finish the baking operation of footwear rapidly, and it is designed to be separated into several districts simultaneously, and therefore the kind according to footwear provides the suitableeest baking temperature.This machine is placed on footwear continuously on the mobile crawler belt and dries, this through type drying means, and each position drying mark of footwear influences the drying and shaping quality of footwear, and not only energy consumption is bigger, and can not recycle heat, causes the waste of energy.01273220.6 in a kind of dry activation equipment baking oven is disclosed.The blowing chamber that it adopts the oblique upper setting in casing to be communicated with upper drying chamber, be provided with the porous barrier of level between upper drying chamber and lower drying chamber, the side cavity of casing both sides is communicated with lower drying chamber by the porous sidewall, is connected with the air channel of crossing that is provided with heating member between the oblique upper of side cavity and the blowing chamber.During use, on blowing chamber, connect air blast, with hot blast be blown into upper drying chamber through porous barrier thoroughly to lower drying chamber to the vamp drying.Hot blast is again through porous sidewall approaching side chamber, is heated by the air channel and returns blowing chamber.Though this device can recycling hot blast, can improve drying effect preferably, but still adopt mode dry on conveyer belt, be subjected to the restriction of its structure, energy consumption and thermal loss are all bigger, still do not reach cut down the consumption of energy, purpose that drying effect is good.Be provided with separately as blowing chamber, upper drying chamber, it is the area occupied of many increases equipment not only, reduces the useful space of hothouse, and increases equipment cost; It is blown into hot blast in the lower drying chamber of semi open model by porous barrier, and the wind brimful of tears that will distribute again is through porous sidewall approaching side chamber, returns the endless form of blowing chamber by the air channel, and its hot blast is obstructed and flows not freely, and circulating effect is relatively poor.This had both reduced energy utilization efficiency, had wasted the energy, caused a large amount of heat-energy losses again.Therefore, existing shoes drying device haves much room for improvement.

The utility model content

The purpose of this utility model provides a kind of hot-air circulation type electric oven for shoe-making, it has solved fundamentally that prior art exists wastes energy, the problem of dry mass difference, its structural design distributes rationally, hothouse effectively utilize the space big, the circulating air temperature that forms is even, compared with prior art, obviously reduces thermal loss, cut down the consumption of energy, significantly improve drying effect and quality.

The purpose of this utility model is achieved in that this device comprises the casing that has chamber door and places casing interior temperature controller and charging car, its technical essential is: the left side of casing, a right side inner panel and a left side, constitute a left side between the three o'clock wind guidance tape, right air path, in each crosswind road electrothermal tube is set, motor-driven centrifugal flabellum is set in the upper air duct that forms between casing top and the windward guidance tape, apodema was with left after the charging car placed casing, in the hothouse that three o'clock wind guidance tape and windward guidance tape surround, the ventilating opening of bottom half communicates with the hothouse bottom, following air guide hole is arranged at each crosswind guidance tape bottom, and make a left side, right air path is communicated with the hothouse bottom, a left side, air channel, right both sides is communicated with the hothouse top by the last air guide hole of windward guidance tape, the end opening that exposes the humidity discharging mouth of casing passes upper air duct and is encapsulated on the windward guidance tape, communicates with hothouse.

The hothouse bottom of described casing is provided with the slide rail into and out of stack pallet,

The thermocouple of described temperature controller passes the upper air duct sealing and fixing and is in the wind in the hothouse of guidance tape below.

Described chamber door is contained on the casing by hinge set, seals by sealing strip and tank surface around the chamber door.

Because the utility model adopts motor-driven centrifugal flabellum to drive hot air circulation, make hot blast be forced to from upper air duct left, right air path flows, the electrothermal tube from top to down heats through hot blast institute, meanwhile, the compressing hot blast enters the hothouse bottom by following air guide hole, arrive the hothouse top by the stack pallet sieve tray from bottom to up again, be inhaled into upper air duct through last air guide hole, finish hot air circulation, so the circulating air temperature that forms is even, can solve fundamentally that prior art exists waste energy, the problem of dry mass difference.In addition, the end opening of the ventilating opening of this device box bottom and the humidity discharging mouth of casing communicates with hothouse, helps moisture and the fuel gas discharge that volatilizes in the dry run, thus the safety, the reliability that reduce the pressure in the casing and guarantee to use.Because of its structural design distributes rationally, circulation air path is provided with compactness, thus hothouse effectively utilize the space big.This device is compared with having the through type drying now, significantly improves drying effect and quality, compares with the conveyor dryer of hot air circulation, can not only reduce the whole area occupied of equipment, make full use of the efficient drying space, and obviously reduce thermal loss, cut down the consumption of energy.Therefore, the utility model is the desirable drying equipment of shoe-making industry.
