Abstract
The utility model discloses an air ducting of a low temperature tempering furnace, which comprises a furnace body. A hearth is arranged in the furnace body and allows a workpiece to be placed; a fan and a heating element are arranged in the hearth; an air ducting is arranged between the heating element and the workpiece; the air ducting comprises a lower air deflector which divides the hearth into an upper cavity and a lower cavity; and an upper air deflector is arranged on the casing wall of the furnace body in the hearth and on the side corresponding to the lower air deflector. In this way, the heat which is generated by the heating element and causes the workpiece to be heated unevenly can be blocked and can not be directly transferred to the workpiece closest to the heating element. The temperature of the workpiece closest to the heating element rises quickly, thereby affecting the product quality. The upper air deflector and the lower air deflector form a hot air channel which can enable the upper cavity and the lower cavity to be communicated with each other, so that the heat entering the hearth where the workpiece is placed is uniform and the workpiece is heated evenly.

The utility model content
Problem to be solved in the utility model is at above problem, and a kind of low-temperaturetempering stove air ducting is provided, and can the hot blast that heating unit produces be led, and workpiece is heated evenly, and has reduced scrap rate, has improved quality product.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of low-temperaturetempering stove air ducting, comprise body of heater, be provided with the burner hearth of place work piece in the body of heater, in burner hearth, be provided with fan and heating unit, be provided with air ducting between described heating unit and the workpiece, this air ducting comprises the following air deflector that burner hearth is separated into upper and lower two chambers, and the body of heater shell wall with the corresponding side of play air deflector in the described burner hearth is provided with air deflector, described between air deflector and the following air deflector formation with upper and lower two hot-air channels that chamber is communicated with.
Below be the utility model for further improvement of these options:
Described down air deflector comprises base plate, upper plate, and the side near last air deflector on the described upper plate is provided with the arc transition face that raises up, and the height of described arc transition face is higher than on the upper plate height with the heating unit corresponding position.
Have sealed hollow between described base plate and the upper plate, in cavity, be filled with lagging material.
Described going up on the air deflector has arc surface, and the arc transition face on this arc surface and the following air deflector is oppositely arranged, and forms the hot-air channel that a cross-sectional width successively decreases successively between the two.
Described both sides up and down of going up air deflector are provided with the last connection section of fixedlying connected with the body of heater shell wall, following connection section, are filled with lagging material in the described space of going up between air deflector and the body of heater shell wall.
The described quantity that goes up air deflector and following air deflector is respectively two, and the corresponding respectively both sides that are arranged on body of heater are provided with the dividing plate that is tightly connected with it between two following air deflectors.
The utility model is taked above technical scheme, have the following advantages: owing between heating unit and workpiece, be provided with dividing plate and following air deflector, the heat that heating unit produces can be intercepted, can not be directly delivered to apart from the nearest workpiece of heating unit, and cause being heated of workpiece inhomogeneous, the workpiece temperature near apart from heating unit rises too fast, influences quality product; The setting of the arc transition face that raises up on the described upper plate, the heat that the heating unit that blown out by fan is produced stops, has slowed down its flow velocity, has also prevented that the mobile hot blast is subjected to stopping of body of heater shell wall simultaneously and returns from the upside of burner hearth; The setting of hot-air channel makes the heat that enters in the burner hearth that is placed with workpiece more even, makes being heated evenly of workpiece.
The utility model is described in further detail below in conjunction with drawings and Examples.
