With simply connected, duplex or three heating zones, quartz or the heating of ceramic cylinder pipe, the material or workpiece being heated to sealing are placed in circle
In column tube.
However, quartz or ceramic cylinder tube chamber are smaller, it is unable to satisfy the test compared with large sample or more batch sample and wants
It asks.For example, in high temperature corrosion test, for the requirement of high temperature corrosion-resisting coating sample test condition: tests exemplar size
> φ 50*5mm (cylinder) or > 80*80*3mm (cuboid) substrate, commercially available equipment size are unable to satisfy testing requirement.Such as
Fruit only expands the sectional dimension of quartz or ceramic tube, then corresponding refractory lining and tubular type furnace volume require further to increase
Greatly, cause equipment heavy and occupy more spaces.On the other hand, large-sized quartz ampoule or ceramic tube cost are high and be easy to brokenly
It splits, also further limits application.
Therefore, it is necessary to improve chamber design on original tubular type furnace foundation, expand corrosion cavity volume, and redesign defeated
Channel is sent, to meet a variety of testing requirements.
Utility model content
To solve the problems, such as that existing tube furnace exists, the utility model proposes improved plans, can not increase pipe
In the case where formula furnace volume, increase the volume of test cavity, to expand the application range of tube furnace.
Technical solutions of the utility model are as follows: a kind of tube furnace for improving burner hearth, including furnace body, conveyance conduit and furnace chamber；Furnace
Chamber is located at furnace interior, for accommodating sample；Conveyance conduit one end is located at outside furnace body, and the other end passes through sidewall of the furnace body and oven cavity side
Wall forms perforation in succession；The area of the furnace chamber side in connecting conveying pipe road is greater than the cross-sectional area of conveyance conduit.
Further, furnace chamber is cuboid or cube, and molding is simple, has flat bottom for placing sample, and
And inner space utilization rate is high.
Further, conveyance conduit is round tube or rectangular tube, convenient for standardization customization.
Further, furnace body two sides are provided with conveyance conduit, convenient to pick and place sample from two sides.
Further, the junction of conveyance conduit and furnace chamber is located at the middle part of furnace chamber side.Conveyance conduit and furnace chamber in this way
Junction and furnace cavity bottom there are difference in height, it is convenient to carry out fused salt corrosion test in furnace cavity bottom and fused salt be from delivery pipe
Road outflow.
Further, conveyance conduit is concordant with the bottom of furnace chamber side with the bottom of the junction of furnace chamber, this feelings
It is the most convenient toward furnace chamber pick-and-place sample under condition.
Further, furnace chamber is the metal cavity that surface coats heat-and corrosion-resistant ceramic coating, is easier to manufacture, cost is more
It is low, not cracky in use, and being capable of high-temperature corrosion resistance.
Compared with the existing technology, the utility model has the advantages that
(1) in the case where not increasing tubular type furnace volume, the volume of test cavity is considerably increased；
(2) sample is picked and placed by conveyance conduit, it is convenient and efficient；
(3) existing tube furnace can be transformed, improvement cost is low.
Detailed description of the invention
Fig. 1 is the 1st kind of structural schematic diagram of tube furnace that the utility model improves burner hearth；
Fig. 2 is the 2nd kind of structural schematic diagram of tube furnace that the utility model improves burner hearth.
Specific embodiment
Embodiment 1
Referring to Fig. 1, a kind of tube furnace improving burner hearth, including furnace body 1, conveyance conduit 2 and furnace chamber 3；Furnace chamber 3 is located at furnace body
Inside 1, for accommodating sample 4；2 one end of conveyance conduit is located at outside furnace body 1, and the other end passes through 1 side wall of furnace body and 3 side wall shape of furnace chamber
In succession at perforation；The area of 3 side of furnace chamber in connecting conveying pipe road 2 is greater than the cross-sectional area of conveyance conduit 2.Furnace chamber shape conduct
Example can be cuboid, and molding is simple, have flat bottom for placing sample, and inner space utilization rate is high.It is defeated
Sending pipeline is round tube, is the most common tube furnace pipeline, convenient for buying and maintenance.For convenient for access sample, furnace body two sides
It is provided with conveyance conduit.The junction of conveyance conduit and furnace chamber is located at the middle part of furnace chamber side, i.e. furnace chamber is set using sunk type
Meter, transfer passage bottom edge and cavity are remained above equal to 20mm difference in height, are easy to send sampling part, while being applicable in fused salt corrosion test
The demand that middle fused salt does not leak.
The tube furnace of the improvement burner hearth is in use, delivery pipe can be protruded into outside furnace body 1 by hand or fixture carrying sample
Sample is placed in furnace chamber 3 by road 2.Similarly, the sample in furnace chamber 3 can be stirred by hand or fixture, and sample is made to be moved to furnace
Any position of 3 bottom surface of chamber greatly improves the storage quantity of sample.If the height of sample is greater than the interior of conveyance conduit 2
Height can fall sample inclination or side, after protruding into the entrance furnace chamber of conveyance conduit 2, then adjust the direction of sample, thereby realize and put
Set the requirement of size more large sample.
Embodiment 2
Referring to fig. 2, a kind of tube furnace improving burner hearth, including furnace body 1, conveyance conduit 2 and furnace chamber 3；Furnace chamber 3 is located at furnace body
