Description
Technical field
The present invention relates to heat-treatment furnace technical fields, more particularly, to a kind of groove type ellipse mouth well formula gas furnace.
Background technique
Well formula gas furnace is suitable for the heat treatment of tube kind part, generally huger, needs to occupy more space.Its furnace
Body is usually columnar deep-well structure, and furnace body inlet is provided with the more hanging bars being parallel to each other, and hanging bar is for installing
The heated work pieces to be added in furnace are hung in by Special crane.It, can only on every hanging bar when shove charge due to the limitation in lifting equipment space
A string of workpiece are hung, the hanging bar two sides that workpiece is located at middle part after being packed into can have biggish idle space, cause furnace inner space sharp
It is lower with rate.
Secondly, the bell of existing shaft furnace mostly uses overall structure or flat type opening and closing left and right structure.The former volume is big heavy
Amount weight, is easy to produce thermal deformation, while the impact in unlatching and closing course to bell and furnace body in the long-term use
Larger, opening and closing speed is slow, operates also very inconvenient；The latter can effectively avoid the shortcomings of overall lid, but in left and right
The binding site of bell can exist compared with big gap, be unfavorable for the sealing of bell, have more energy in heating and insulating process
Amount loss, causes the waste of the energy.
Again, the heat exchanger of most shaft furnace is all made of cellular structure, is easy blocking in the long-term use, needs
Periodically cleared up, it is inconvenient for use.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of groove type ellipse mouth well formula gas furnace, can take following technology
Scheme:
Groove type ellipse mouth well formula gas furnace of the present invention, including furnace body, the furnace body top are provided with support frame and lead to
The flat-open type bell of mechanism for opening/closing driving is crossed, hanging cross bar is provided on support frame as described above, is provided with and wears on the hanging cross bar
It crosses flat-open type bell and extends to the hanging vertical bar in furnace body inner cavity, be provided with the temperature being electrically connected with control unit in furnace body inner cavity
Sensor and pressure transmitter are spent, is provided with the gas combustion mechanism being connected with air supply system, bottom of furnace body on sidewall of the furnace body
Side is provided with the exhaust heat exchanger being connected with furnace body inner cavity, and the sidewall of the furnace body is by left side wall disposed in parallel and right side
Wall and the semicircular wall for being connected to the left and right side walls both ends are constituted, and support frame as described above is arranged in pairs in left and right side walls
On, the hanging cross bar is arranged along left and right side walls longitudinally parallel interval, and the hanging vertical bar is along the symmetrical of left and right side walls
Axis arrangement；The flat-open type bell includes left cover and right cover, is provided on the opposite face of the left cover and right cover and hanging vertical bar
Corresponding holding hole and vertical Z-shaped sealing and bonding structure；The exhaust heat exchanger is through type heat exchanger.
Groove type ellipse mouth well formula gas furnace provided by the invention is identical in batch using the furnace body of ellipsoidal structure
In the case where, oval furnace body reduces 35% than the burner hearth area of typical round furnace body, substantially increases the utilization of furnace cavity
Rate saves furnace body occupied area, meanwhile, facilitate work piece hoisting；Bell uses the flat-open type structure of left and right split, opening and closing speed
It spends fast, easy to operate, the impact that bell and furnace body are subject in opening-closing process is reduced, simultaneously as in the spelling of left cover right cover
It is provided with mutually matched L shape on conjunction face and splices slot, it is ensured that bell is effectively sealed, and is more energy-saving and environmentally friendly；Smoke evacuation is changed
When hot device uses through type heat exchanger, it is possible to prevente effectively from blocking in use, maintenance downtime is reduced, is improved
To the heating efficiency of workpiece.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram of flat-open type bell in Fig. 1.
Fig. 3 is the top view (only oven body part) of Fig. 1.
Fig. 4 is the left view (part) of Fig. 1.
Specific embodiment
As shown in Figs 1-4, groove type ellipse mouth well formula gas furnace of the present invention, including furnace body 1, the side of the furnace body 1
Wall is by left side wall disposed in parallel and right side wall and to be connected to the ellipse that the semicircular wall at left and right side walls both ends constitutes
Shape structure.A pair of supporting 2 is installed at the top of the left and right side walls of furnace body 1, the support frame 2 is for setting up hanging cross bar 3, hanging
It is 3 in cross bar 3(figure) it is horizontally placed on 1 top of furnace body, and be arranged along left and right side walls longitudinally parallel interval, every hanging is horizontal
3 center of bar is respectively connected with the hanging vertical bar 4 extended in furnace body inner cavity, and every hanging vertical bar 4 is respectively positioned on left and right side walls
In central symmetry axis.When only lifting a string of workpiece Q on every hanging vertical bar 4, on the outside of the hanging vertical bar 4 at 1 both ends of furnace body,
And 4 left and right sides of hanging vertical bar is located in the middle without idle space, the utilization rate of furnace cavity is substantially increased, is reduced
The occupied area of gas furnace.
The flat-open type bell 6 driven by mechanism for opening/closing 5 is also equipped at the top of furnace body 1, which includes left cover
And right cover is additionally provided on the opposite face of left cover and right cover other than opening up and making to hang the holding hole that vertical bar 4 passes through by mutual
The splicing slot 7 of cooperation constitutes vertical Z-shaped sealing and bonding structure.When furnace body 1 works, left and right lid is fastened on hanging 4 two sides of vertical bar
And split is sealed, effectively furnace heat can be made to be obstructed in uphill process, reduce the loss of heat in heating and insulating process, more
Add energy conservation and environmental protection.
The temperature sensor 8 and pressure transmitter 9 being electrically connected with control unit, 1 side wall of furnace body are installed in 1 inner cavity of furnace body
On be provided with and supply be 10 gas combustion mechanisms 11 being connected, 1 bottom side of furnace body is equipped with to be connected with 1 inner cavity of furnace body
Exhaust heat exchanger 12, which can be used institute in through type double loop heat storage water tank (ZL201720253442.6)
The through type heat exchanger stated, heat exchanger diameter of bore is larger, it is possible to prevente effectively from use process clogging generation, subtract
Few maintenance downtime.In addition to this it is possible to which the heat exchanger of blocking can be prevented using other.
