Abstract
The utility model relates to the technical field of heating devices of heat circulation, in particular to a heated air circulation device which is used to roast heat shrinkable tubes and enable the heat shrinkable tubes to shrink. The heated air circulation device is additionally equipped with a return air duct, a first end of the return air duct is equipped with an air suction opening, the air suction opening is located above a heated air outlet of an air outlet duct, a second end of the return air duct is connected with an air inlet of a blower, heated air blown by the heated air outlet is sucked into the return air duct via the air suction opening, and is pushed to the air outlet duct via the blower, thereby circularly utilizing the heated air, increasing heated air utilization rate and saving energy, simultaneously, most of heated air blown from the heated air outlet is recycled and reused, thereby effectively preventing the heated air dissipating in a workshop to increase the temperature of the workshop, reducing the load of air-conditioners in the workshop, and reducing energy consumption of the air-conditioners.
Description
Technical field:
The utility model relates to the heating device technology area of heat circulation, more specifically to a kind of heated air circulation device of toasting heat-shrink tube and making its thermal contraction of being used to.
Background technology:
Usually, cable is made up of some heart yearns, screen layer and oversheath, and heart yearn is by conductor and be coated on the outer field insulating barrier of conductor and form, and the effect of insulating barrier mainly is that the conductor that prevents heart yearn contacts with each other and short circuit.For cable and connector can be electrically connected, generally the insulating barrier with each heart yearn end divests, and makes conductor expose out and electrically connects with the terminal of connector.But be subjected to the restriction of the connector construction and the construction of cable, the phenomenon that can occur unavoidably between each heart yearn intersecting He nestle mutually, and the insulating barrier of heart yearn may be damaged in taking off operations such as screen, welding causes occurring short circuit, withstand voltage phenomenon such as bad.In order to prevent above bad phenomenon; generally overlap the preceding paragraph heat-shrink tube in the periphery of heart yearn or bare exposed conductor; use heater such as thermal chimney that heat-shrink tube is toasted, make heat-shrink tube be subjected to thermal contraction and tightly be attached to the periphery of heart yearn or conductor, protection core insulation and conductor.
At present, article one, production line is provided with several thermal chimneys at the baking heat-shrink tube, hot blast blows out from air duct from bottom to top, the air outlet of air duct is the opened type structure, and the bore of air outlet is bigger, and the diameter of heat-shrink tube and length are all less, have only the hot blast of a few part to be used to toast heat-shrink tube, remaining hot blast all directly blows in the air, and most of heat is wasted, and energy utilization rate is low; Simultaneously, because workshop is an air-conditioned workshop, a large amount of hot blasts is dissipated in the air, can make the rising of the environment temperature in workshop to a certain extent, causes the energy consumption of air-conditioning to increase.
The utility model content:
The purpose of this utility model is to provide a kind of heated air circulation device at the deficiencies in the prior art, and the hot blast that it will blow out is reclaimed with recycling, improves the utilization rate of hot blast, energy savings.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of heated air circulation device, it comprises blower fan, wind pipe, return air duct and heater element, the fan outlet of blower fan connects first end of wind pipe, heater element is arranged in the wind pipe, second end of wind pipe is provided with the hot blast air outlet, first end of return air duct is provided with the inlet scoop, and the inlet scoop is positioned at the top of the hot blast air outlet of wind pipe, and second end of return air duct connects the air inlet of blower fan.
Described inlet scoop is the funnel shaped of turned upside down.
Second end of described wind pipe is provided with a temperature sensor.
Second end of described wind pipe is provided with two lug bosses, is installed with a material-putting space that is used for ccontaining thing to be processed between two lug bosses, and the medial surface of two lug bosses offers a hot blast air outlet respectively.
Described hot blast air outlet is a strip.
Described heater element is a heating wire.
The beneficial effects of the utility model: the utility model has increased a return air duct, first end of return air duct is provided with the inlet scoop, the inlet scoop is positioned at the top of the hot blast air outlet of wind pipe, second end of return air duct connects the air inlet of blower fan, the hot blast that the hot blast air outlet is blown out sucks return air duct through the inlet scoop, push to wind pipe through blower fan again, recycling hot blast, the utilization rate of raising hot blast, energy savings, simultaneously, most of hot blast that the hot blast air outlet blows out is recycled, prevented that effectively hot blast is dispersed in the workshop, the workshop temperature is raise, reduce the load of workshop air-conditioning, reduce air conditioning energy consumption.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Heated air circulation device is seen accompanying drawing 1, it comprises blower fan 1, wind pipe 2, return air duct 3 and heater element 4, described heater element 4 is a heating wire, the fan outlet of blower fan 1 connects first end of wind pipe 2, heater element 4 is arranged in the wind pipe 2, second end of wind pipe 2 is provided with hot blast air outlet 5, first end of return air duct 3 is provided with inlet scoop 6, inlet scoop 6 is the funnel shaped of turned upside down, inlet scoop 6 is positioned at the top of the hot blast air outlet 5 of wind pipe 2, and second end of return air duct 3 connects the air inlet of blower fan 1.The hot blast that hot blast air outlet 5 is blown out is 6 suction return air ducts 3 through the inlet scoop, push to wind pipe 2 through blower fan 1 again, recycling hot blast, the utilization rate of raising hot blast, energy savings, simultaneously, most of hot blast that hot blast air outlet 5 blows out is recycled, prevented that effectively hot blast is dispersed in the workshop, the workshop temperature is raise, reduce the load of workshop air-conditioning, reduce air conditioning energy consumption.
Second end of described wind pipe 2 is provided with a temperature sensor 7, the temperature of the hot blast at 7 pairs of hot blast air outlet 5 places of temperature sensor is measured, when the temperature of the hot blast of this position reaches the temperature of setting, heating wire stops heating, when the temperature of the hot blast of this position is lower than the temperature of setting, the heating wire heating.
