Abstract
The utility model discloses an installation structure of electric heating tubes in an electric heating aluminum brazing degreasing furnace, which comprises a heat insulation furnace body, a circulating wind chamber and a hearth. The circulating wind chamber and the hearth are arranged inside the heat insulation furnace body, low ends on two lateral sides of the circulating wind chamber are communicated with the bottom the hearth, a circulation fan is disposed on the heat insulation furnace body at the upper end of the circulating wind chamber, a plurality of electric heating tubes are evenly distributed on two sides of the circulating wind chamber, the upper end of each of the electric heating tubes is fixed at the upper end of the heat insulation furnace body, and the lower end of each of the electric heating tubes enters the two sides of the circulating wind chamber. The installation structure has the advantages that when in use, volatile oil, other non-hydrophiles and micro solid particles on workpieces can not fall to the electric heating tubes, and service life of the electric heating tubes is prolonged.
Description
Technical field
The utility model relates to a kind of aluminum soldering thermal debinding furnace, relates in particular to the mounting structure of electrothermal tube in a kind of electrical heating 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.The structure of the mounting structure of electrothermal tube mainly comprises in the conventional electric heating aluminum soldering thermal debinding furnace: thermal insulation furnace body, pass the conveyer belt in the thermal insulation furnace body, be arranged on the some circulating fans on the thermal insulation furnace body, the lower end of circulating fan is provided with the circulation air compartment that cooperatively interacts with circulating fan in thermal insulation furnace body, the lower end, both sides of circulation air compartment and the bottom of burner hearth are interconnected, and evenly are provided with some electrothermal tubes in the burner hearth below conveyer belt.In use, the volatile oil on the workpiece and other non-hydrophile and small solid particle drop on the electrothermal tube easily, influence the service life of electrothermal tube.
The utility model content
Technical problem to be solved in the utility model is: a kind of mounting structure that can prolong electrothermal tube in the electrothermal tube electrical heating aluminum soldering thermal debinding furnace in service life is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the mounting structure of electrothermal tube in the electrical heating 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, the thermal insulation furnace body of circulation air compartment upper end is provided with circulating fan, on the both sides of described circulation air compartment, evenly be provided with some electrothermal tubes, the upper end of electrothermal tube is fixedly installed on the upper end of thermal insulation furnace body, and the lower end of electrothermal tube extend in the both sides of circulation air compartment.
The utility model has the advantages that: the mounting structure of electrothermal tube in the above-mentioned electrical heating aluminum soldering thermal debinding furnace, in use, volatile oil on the workpiece and other non-hydrophile and small solid particle can not drop on the electrothermal tube, have prolonged the service life of electrothermal tube.
Description of drawings
Fig. 1 is the structural representation that the electrical heating aluminum soldering thermal debinding furnace of the mounting structure of electrothermal tube in the utility model electrical heating aluminum soldering thermal debinding furnace is housed.
Among the figure: 1, thermal insulation furnace body, 2, the circulation air compartment, 3, burner hearth, 4, circulating fan, 5, electrothermal tube, 6, workpiece, 7, 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, the mounting structure of electrothermal tube in the electrical heating 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, the thermal insulation furnace body 1 of circulation air compartment 3 upper ends is provided with circulating fan 4, on the both sides of described circulation air compartment 2, evenly be provided with some electrothermal tubes 5, the upper end of electrothermal tube 5 is fixedly installed on the upper end of thermal insulation furnace body 1, and the lower end of electrothermal tube 5 extend in the both sides of circulation air compartment 2.
When the electrical heating aluminum soldering thermal debinding furnace that the mounting structure of above-mentioned electrothermal tube is housed uses, workpiece 6 is transported in the burner hearth 3 by the conveyer belt 7 that passes thermal insulation furnace body 1 inside, the hot blast that electrothermal tube 5 heating produce is by circulating fan 4 constantly circulation in circulation air compartment 2 and burner hearth 3, to carrying out ungrease treatment through the workpiece 6 in the burner hearth 3, the volatile oil on the workpiece 6 and other non-hydrophile and small solid particle are removed.The high-temp waste gas that produces during processing is discharged by Waste gas outlet.Processing is transported to next operation by conveyer belt 7 with workpiece 6 after finishing.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model spirit and protection domain; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present utility model.
