Abstract
The utility model discloses a hot blast flow guide structure in an aluminum soldering thermal degreasing furnace. The structure comprises: a thermal insulation furnace body, a circulating air chamber arranged in the thermal insulation furnace body, and a hearth, wherein the lower ends at two sides of the circulating air chamber are communicated with the bottom of the hearth; the hearth is internally provided with a furnace pipe; the thermal insulation furnace body at the upper end of the circulating air chamber is provided with a circulating fan; and a flow guide plate is arranged at the central position at the bottom of the hearth. The advantages are as follows: the corners at two sides of the upper end of the circulating air chamber are in arc transition; the hot blast passes through the corners smoothly due to small resistance; and when entering the lower end of the hearth, two ways of hot blast are not easy to converge, thus keeping the temperature in the hearth uniform and improving the degreasing effect.

Technical field
The utility model relates to a kind of aluminum soldering thermal debinding furnace, relates in particular to the hot blast flow-guiding structure in a kind of aluminum soldering thermal debinding furnace.
Background technology
Aluminum brazing furnace is a kind of equipment that each parts of aluminum heat exchanger are effectively connected.Be that this characteristic of fusing point of utilizing the alloy melting point of almit to be lower than aluminum metallic material is welded.Solder places near the solder side that needs connecting portion or the inside usually; between parts and solder side, reach the surface and scribble the NOCOLOK aluminum brazing flux; after drying was installed, parts were heated to the brazing alloy fusion and the nonfused temperature of parts metal under certain inert gas shielding.Used inert gas is generally nitrogen.The NOCOLOK aluminum brazing flux is broken the oxide-film of aluminium simultaneously, allows and carries out diffusion into the surface between its motlten metal and the infusible metal, and after the cooling, braze metal will combine with formation metal between the parts contact-making surface.
Under normal conditions, need to assemble many fin on the aluminum heat exchanger, its surface is attached with many volatile oil and other non-hydrophile and small solid particle in process.Volatile oil is a kind of ready-mixed oil, and it is made up of volatile matter and involatile matter, and involatile matter could volatilize and volatilize not thorough at normal temperatures through the regular hour, and the volatilization quality is also inconsistent.These materials must clean and utilize thermal debinding furnace that it is carried out ungrease treatment, just can carry out the spray and the coating of aluminum brazing flux, otherwise aluminum brazing flux can not can not carry out aluminium soldering effectively attached to the surface of interior weldering thing.Hot air circulation structure in the existing thermal debinding furnace mainly comprises: thermal insulation furnace body, be arranged on some circulation air compartments and burner hearth in the thermal insulation furnace body, the lower end, both sides of circulation air compartment and the bottom of burner hearth are interconnected, be provided with flue in burner hearth, the thermal insulation furnace body of circulation air compartment upper end is provided with circulating fan.Existing burner hearth lower end is a slab construction, the turning of circulation air compartment both sides is the right angle transition, in the hot air circulation process, hot blast is easy to generate resistance by right angle turn the time, hot blast is when entering the burner hearth lower end, and two strands of hot blasts meet at together, and is disorderly easily, make the non-uniform temperature in the burner hearth, influence degreasing effect.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can make the hot blast flow-guiding structure in the uniform aluminum soldering thermal debinding furnace of temperature in the burner hearth.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the hot blast flow-guiding structure in the aluminum soldering thermal debinding furnace, comprise: thermal insulation furnace body, be arranged on circulation air compartment and burner hearth in the thermal insulation furnace body, the lower end, both sides of circulation air compartment and the bottom of burner hearth are interconnected, be provided with flue in burner hearth, the thermal insulation furnace body of circulation air compartment upper end is provided with circulating fan, and the centre position of described burner hearth bottom is provided with deflector.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: described deflector is to be spliced by two circular arc plates, the upper end of two circular arc plates welds together, and the lower end of two circular arc plates is welded on respectively on the bottom of burner hearth.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: turning, both sides, described circulation air compartment upper end is an arc-shaped transition.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: the lower end, both sides at described circulation air compartment is respectively arranged with arc deflector.
The utility model has the advantages that: the hot blast flow-guiding structure in the above-mentioned aluminum soldering thermal debinding furnace, turning, both sides, circulation air compartment upper end is an arc-shaped transition, resistance was less when hot blast passed through the turning, hot blast is by smooth and easy, hot blast is when entering the burner hearth lower end, two strands of hot blasts are difficult for meeting at together, make the temperature in the burner hearth keep evenly having improved degreasing effect.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the hot blast flow-guiding structure in the utility model aluminum soldering thermal debinding furnace.
Among the figure: 1, thermal insulation furnace body, 2, the circulation air compartment, 3, burner hearth, 4, flue, 5, circulating fan, 6, deflector, 61, the circular arc plate, 62, arc deflector, 7, heater, 8, workpiece, 9, conveyer belt.
The specific embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, hot blast flow-guiding structure in the aluminum soldering thermal debinding furnace, comprise: thermal insulation furnace body 1, be arranged on circulation air compartment 2 and burner hearth 3 in the thermal insulation furnace body 1, the lower end, both sides of circulation air compartment 2 and the bottom of burner hearth 3 are interconnected, be provided with flue 4 in burner hearth 3, the thermal insulation furnace body 1 of circulation air compartment 2 upper ends is provided with circulating fan 5, and the centre position of described burner hearth 3 bottoms is provided with deflector 6.
In the present embodiment, described deflector 6 is to be spliced by two circular arc plates 61, and the upper end of two circular arc plates 61 welds together, and the lower end of two circular arc plates 61 is welded on respectively on the bottom of burner hearth 43.
In the present embodiment, turning, both sides, described circulation air compartment 2 upper end is an arc-shaped transition.
