Specific embodiment

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

As illustrated in fig. 1-3, heated-air circulation oven, including a cabinet 1, the side wall of the cabinet 1 are hollow setting and structure At a heat-insulated cavity 2, it is filled with insulating layer 3 in heat-insulated cavity 2, double door 4 is equipped in the front end of cabinet 1, the two of cabinet 1 Inside sidewalls are respectively equipped with an inner cover 5, and 1 inner wall of cabinet on the corresponding position in both ends of the inner cover 5 abuts against, described interior An air duct 6 is formed between cover 5 and 1 inner sidewall of cabinet, is divulged information in the middle part surface of the opposing sidewalls of two inner covers, 5 plate equipped with several Mouth 7 is equipped with a pedestal 8 in cabinet 1, and the pedestal 8 is connected in 1 upper bottom portion of cabinet by supporting leg 9, between the top of cabinet 1 Every being equipped with two air blowers 10, the outlet end of two air blowers 10 is connected with 6 import of air duct on corresponding position respectively, in each air duct 6 It is inside respectively equipped with a heating tube group 11, several air pressure balance mouths 12 are equipped on cabinet 1, are equipped on the lateral wall of cabinet 1 One electric cabinet 13, electric cabinet 13 are connected by conducting wire with each air blower 10, heating tube group 11, and temperature is equipped in cabinet 1 and is passed Sensor is directly connected with the general temperature display controller in electric cabinet 13；When need using the present apparatus to product material carry out When drying heat treatment, the double door 4 of the present apparatus is opened, the frame body for filling drying product push is placed in this cabinet 1 Pedestal 8 on, be then shut off double door 4, operator controls electric cabinet 13 and powers on, and then controls each heating tube group 11 Fever, so that the operation range of air blower 10 is controlled by control electric cabinet 13, thus to carry out to heating up inside cabinet 1 The regulation of air quantity and wind speed, hot wind under the action of air blower 10 in cabinet 1 is in flow regime, so as to warp repeatedly The surface for crossing product to be dried handles it, and the air pressure balance mouth 12 of setting can play the work of auxiliary balance air pressure With insulating layer 3 can effectively lock heat, heat losses be reduced, so as to quickly handle product, at raising Manage effect and efficiency.

Each ventilation opening 7 is horizontally disposed, the convection current of the hot wind on horizontal plane may be implemented, so as to effectively to product Two sides carry out drying and processing.

It is equipped with a up-draught channel 14 on the top of each inner cover 5, is equipped on several on the end face in up-draught channel 14 Air port 15, the hot wind blown by air blower 10 are directly blown out by each uptake 15 in up-draught channel 14, wind-force at this time It is more powerful, therefore the uptake 15 being arranged is minimum compared with ventilation opening 7,17 aperture of lower air port, so as to effectively by it His air quantity is transferred to corresponding ventilation opening 7, lower air port 17 is discharged again out, to form the reasonable blowout of air quantity, realizes multiple Orientation is blowed, dries, while the hot air circulation time cycle is longer, preferably can carry out drying and processing to stock product, High treating effect.

The inner end in the up-draught channel 14 tilts down setting, and the hot wind blown by air blower 10 is directly by up-draught Channel 14 is sprayed onto the top of the frame body equipped with product obliquely, so as to effectively quickly be brushed the top of product Drying.

The up-draught channel 14 and the angle of 5 side wall of inner cover are 30 degree, by the folder in up-draught channel 14 and 5 side wall of inner cover Angle is 30 degree, commutate the outlet end of air hose 16 and the angle of 5 side wall of inner cover is 30 degree of convection current that can effectively realize hot wind, from And the hot wind after capable of effectively impacting convection current concentrates on the middle part of cabinet 1, so as to keep the hot wind of middle part head-on collision direct It is contacted with the product of tape handling, promotes the drying effect of product.

Be respectively separated in the opposing sidewalls of each inner cover 5 equipped with several air hoses 16 that commutate, it is each commutate air hose 16 respectively from The opposite side of cabinet 1 is passed through and extended in space between pedestal 8 and cabinet 1.

The top of the outlet end of each commutation air hose 16 tilts obliquely, sets on the end face of the outlet end of commutation air hose 16 There are several lower air ports 17.

The outlet end of the commutation air hose 16 and the angle of 5 side wall of inner cover are 30 degree, convection effects under such state most It is good, even if there is the blocking of frame body, the impact of part hot air convection can be also effectively realized, it can be to product herein after hot air convection It is effectively blown and is dried, good drying effect.

The uptake 15, ventilation opening 7, lower air port 17 aperture be sequentially increased setting, the heat blown by air blower 10 Wind is directly blown out by each uptake 15 in up-draught channel 14, and wind-force at this time is more powerful, therefore the uptake 15 being arranged It is minimum compared with ventilation opening 7,17 aperture of lower air port, so as to effectively by other air quantity be transferred to corresponding ventilation opening 7, under Air port 17 is discharged again out, to form the reasonable blowout of air quantity, realizes that multiple orientation are blowed, dry, while hot wind follows The ring time cycle is longer, preferably can carry out drying and processing, high treating effect to stock product.

Before use, opening the double of the present apparatus when needing to carry out drying heat treatment to product material using the present apparatus and opening The frame body for filling drying product is pushed on the pedestal 8 being placed in this cabinet 1, is then shut off double door 4, operator by door 4 Member's control electric cabinet 13 powers on, and then controls each heating tube group 11 and generates heat, to pass through control to heating up inside cabinet 1 Electric cabinet 13 processed controls the operation range of air blower 10, thus to carry out the regulation of air quantity and wind speed, in the work of air blower 10 It is in flow regime with the hot wind in lower box 1, so as to the surface by product to be dried repeatedly at it Reason, the air pressure balance mouth 12 of setting can play the role of auxiliary balance air pressure, and insulating layer 3 can effectively lock heat, subtract Few heat losses improve treatment effect and efficiency so as to quickly handle product.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
