Accompanying drawing is the embodiments of the invention structure chart.
The specific embodiment
For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present invention and beneficial effect more, the applicant general elaborates in conjunction with the accompanying drawings in the mode of embodiment below, but to the description of embodiment all is not restriction to the present invention program, any according to the present invention's design done only for pro forma but not substantial equivalent transformation all should be considered as technical scheme category of the present invention.
Ask for an interview accompanying drawing, the body of heater that provides in the drawings 5 is the bell jar stove, is installed with a ring pipe 51 on the top of body of heater 5 and is provided with a thermoelectric pot 52 of temperature that is used for the burner hearth of perception body of heater 5 at the middle part of the short transverse of body of heater 5.The circumferencial direction of aforesaid ring pipe 51 connects one group of joint 511 that communicates with the tube chamber of ring pipe 51 at interval; and each joint 511 communicates with the burner hearth of body of heater 5; the protective gas of being drawn by protective gas circulating reflux mechanism 4 for example nitrogen or argon gas is introduced in the tube chamber of ring pipes 51 through snorkel 5121 and air entraining pipe 512, and then is introduced in the burner hearth of bodies of heater 5 by each joint 511.Specifically: on ring pipe 51, connect air entraining pipe 512, on air entraining pipe 512, connect an end of snorkel 5121, and the other end of snorkel 5121 is connected with the following protective gas circulating reflux mechanism 4 that also will describe in detail.
Though the described in the above body of heater 5 of applicant is defined as the bell jar stove, but do not repel for example air furnace of other firing furnace,, that is to say because the bell jar stove belongs to the atmosphere furnace category, the cooling back installation that is provided by the applicant is not limited to supporting on the bell jar stove, and other kiln is also suitable fully.
Continue to see accompanying drawing, the preferred construction of the cooling back installation that provides is as follows, and a support 1 that is made of many supporting legs is fixed in body of heater 5 places under user mode or title is followed in body of heater 5.One is shaped as the cylindrical shell 2 of cuboid to weld or to rivet or to be fixed on the support 1 with other similar fixed form, at the upper lateral part of the short transverse of cylindrical shell 2 is that illustrated right side is connected with the cooling medium that is used for the cooling medium in the tube chamber 23 of cylindrical shell 2 is drawn and draws interface 22, and be that illustrated rear lateral portion (back) is connected with a cooling medium that is used for cooling medium is introduced the tube chamber 23 of cylindrical shell 2 and introduces interface 21 in the following side of the short transverse of cylindrical shell 1, and also connected an exhaust-valve 24 in the bottom of cylindrical shell 2, this exhaust-valve 24 had both played to be got rid of the accumulation thing in the tube chamber 23, plays the effect with the discharging of the cooling medium in the tube chamber 23 again.Aforementioned cooling medium both can be a water, also can be frozen water, specifically selected usefulness according to arts demand and actual conditions.Aforesaid cooling medium is introduced interface 21 and is drawn the position relation that interface 22 keeps the diagonal angle to be provided with cooling medium on cylindrical shell 1.
The condenser pipe 3 that the applicant recommends is unique one, and is to be placed in agley in the chamber 23, and preferred curved shape is U-shaped body (present embodiment promptly is).The protective gas of the upper end of condenser pipe 3 draws port 31 and protective gas inlet port 32 all is stretched over outside the chamber 23; promptly be stretched over outside the cylindrical shell 2; and the lower end of condenser pipe 3 is stretched over outside the chamber 23 equally; promptly be stretched over outside the cylindrical shell 2; and received a discharge opeing interface 33; on discharge opeing interface 33, connected a liquid level gauge 331, when the indicating value of foundation liquid level gauge 331 need with the moisture content in the tube chamber of condenser pipe 3 put except that the time, then open the valve (not shown) that connects on discharge opeing interface 33.Aforesaid protective gas is drawn port 31 and is connected with protective gas circulating reflux mechanism 4, and aforesaid protective gas inlet port 32 connects with the burner hearth of body of heater 5 by pipeline 321 and communicates with burner hearth.Specifically be to have received a port adapting flange 322 at the sidepiece of protective gas inlet port 32; one end of aforesaid pipeline 321 (being illustrated upper end) connects with port adapting flange 322; and the other end of pipeline 321 (being illustrated lower end) connects with body of heater 5 and communicate with the furnace chamber of body of heater 5, is furnished with usually on pipeline 321 and has the valve (not shown) of regulating the flow size.Protective gas in the burner hearth is incorporated in the tube chamber of condenser pipe 3 through port adapting flange 322 self-shield gas inlet ports 32 by pipeline 321, draws until drawing port 31 from the protective gas of condenser pipe 3.
Then see accompanying drawing; preferably but not the structure of the protective gas circulating reflux mechanism 4 that definitely is limited to is as follows; comprise motor 41 and centrifugal blower 42; centrifugal blower 42 connects with motor 41; the blower fan escape pipe 421 of centrifugal blower 42 is connected with air entraining pipe 512 by aforesaid snorkel 5121 and communicates; on blower fan escape pipe 421, also be connected to a relief tube 4211 of being furnished with relief valve 42111; when the hypertonia of protective gas; then open relief valve 42111 pressure releases; to ensure safety, 422 of the fan inleting pipes of centrifugal blower 42 are drawn port 31 with aforesaid protective gas and are connected.
The applicant describes the course of work of the present invention in conjunction with the accompanying drawings, at first the present invention is pressed shown in the figure and according to the superincumbent explanation of applicant and docks with body of heater 5.When illustrated bell jar stove has been finished when electronic devices and components are for example needed to cool off behind the sintering of the electronic product of multiple-layer sheet ceramic capacitor and so on; then open the motor 41 of protective gas circulating reflux mechanism 4; close relief valve 42111 and close exhaust-valve 24 and close the valve that continues on discharge opeing interface 33, open valve and the valve of opening on the pipeline 321 on the cooling medium pipeline.Cooling medium is introduced interface 21 from cooling medium and is introduced the tube chamber 23 of cylindrical shell 2, draws interface 22 by cooling medium simultaneously and draws, and forms circulation.Meanwhile the protective gas in the burner hearth of body of heater 5 is drawn by pipeline 321; cause protective gas inlet port 32 from port adapting flange 322; enter the tube chamber of condenser pipe 3; draw port 31 by the cooling of the cooling medium in the cylindrical shell 2 back from protective gas and draw, cause for 511 times in the burner hearth of body of heater 1 through protective gas circulating reflux mechanism 4, snorkel 5121, air entraining pipe 512, ring pipe 51 and joint.So circulation can with in the burner hearth up to 1000 ℃ about high-temperature gas reduce to through the cooling back installation of electronic component burning furnace of the present invention and be about about 60 ℃.
In sum, technical scheme provided by the invention has reached goal of the invention, has overcome the shortcoming of prior art all sidedly, has embodied due technique effect, is a ultimate attainment technical scheme.
