Abstract
The utility model relates to a heating device for a polyurethane casting machine. The heating device comprises a sealed oven, wherein a charging bucket is arranged at the upper part in the oven; the bottom end of the charging bucket is communicated with a feeding tube; an insulating layer is arranged at the periphery of the oven; a circulating fan is arranged on the lateral wall at the upper part of the inner side of the oven; an air hose is correspondingly arranged at an air outlet of the circulating fan; the air hose is arranged inside the oven; an air outlet of the air hose inclines downwards to correspond to the lower part of the bottom of the charging bucket; a heater strip is arranged inside the air hose. The heating device has the beneficial effects that the problem that the charging bucket is slow to heat up, uneven to heat, and difficult to maintain and preserve, and easily block a tube of the feeding tube are effectively solved by the heating device for the polyurethane casting machine, disclosed by the utility model, the running and leakage phenomena of heat-conducting oil are avoided, and the heating device is relatively environmentally-friendly, and insulated by adopting the oven, so that the heating device is small in heat loss, and high in heating efficiency. Thus, the heating device has the relatively energy-saving effect.
Description
Technical field
The utility model relates to a kind of heater of polyurethane casting machine.
Background technology
?the heater of polyurethane casting machine generally adopts the mode of conduction oil chuck heating to heat batch can, measuring pump, material pipe in the market, this kind of structure is owing to using heat-conductive-oil high-temperature heating, easily produce carbon distribution, stop up oil line pipe, cause the internal temperature reduction of conveying pipeline to make temperature of charge because solidifying lower than fusing point, make to produce and cannot normally carry out; Owing to using heat-conducting oil heating, the specific heat ratio of oil is higher, conventionally heats and all needs the heat time of 1-2 hour to required environment temperature, has taken the production time, greatly reduces service efficiency; Owing to using conduction oil chuck heating (double-skin duct, skin be heat conducting oil pipe, nexine is managed for expecting), bring inconvenience to maintaining, environmental pollution is also more serious.
Utility model content
The purpose of this utility model is to provide a kind of heater of polyurethane casting machine, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of heater of polyurethane casting machine, comprise the baking oven of sealing, the inner and upper of described baking oven is provided with batch can, the bottom of described batch can is communicated with material pipe, the outer heat-insulation layer that is arranged with of described baking oven, and the sidewall of described baking oven inside upper part is provided with circulating fan, the air outlet place correspondence of described circulating fan is provided with airduct, described airduct is arranged in baking oven, and the air outlet of described airduct is tilted to the below of lower corresponding batch can bottom, and described airduct inside is provided with heater strip.
Further, described material pipe tail end is communicated with measuring pump, and described measuring pump is arranged in baking oven.
Further, described oven interior is provided with some temperature sensors.
The beneficial effects of the utility model are: the heater of polyurethane casting machine of the present utility model efficiently solves batch can and heats up slowly, be heated inhomogeneous, and maintaining difficulty, the susceptible to plugging problem of material pipeline; Because this heater does not adopt heat-conducting oil heating, avoid the evaporating, emitting, dripping or leaking of liquid or gas phenomenon of conduction oil, thus environmental protection more; Owing to having adopted baking oven insulation, heat loss is little in addition, and heat exchange efficiency is high, is heated evenly, and the efficiency of heating surface is high, makes this heater more energy-conservation.
