Specific embodiment
It is illustrated in more detail below with reference to Fig. 1-4 pairs of technical solutions provided by the invention.
Embodiment 1
It as shown in Figure 1, 2, is the water heater liner application of slip sintered production line of the embodiment of the present invention comprising:
Application of slip device 100, in the inner surface application of slip at least one layer form porcelain glaze slurry to enamel inner container；
Drying oven 200, for the form porcelain glaze slurry on the liner to be dried to perfect condition；
Sintering furnace 300, the liner for being in perfect condition to form porcelain glaze slurry are sintered, and form enamel inner container；
The production line further includes having a conveying device 400 for sequentially passing through the drying oven and sintering furnace, at work, institute
The liner that at least two layers inner surface application of slip at least one layer form porcelain glaze slurry is hung in conveying device is stated, and the liner is successively defeated
It send into drying oven and sintering furnace.
The application of slip sintered production line of application of slip sintered production line compared to the prior art, the embodiment of the present invention passes through setting one
The conveying device for sequentially passing through drying oven and sintering furnace is hung after liner application of slip form porcelain glaze slurry on the application of slip device
At least two layers of liner is hung in conveying device and on a conveyor, and the height where every layer of liner is different, it is wrong to form height
Two layers of the hanging liner fallen, and then it is conveyed into drying oven and sintering furnace progress next process again.So that the embodiment of the present invention
Sintered production line can substantially increase production efficiency compared with prior art with twice or more times of liner of first drying sintering.
Wherein, the conveying device includes the second conveying section being arranged in drying oven, the third being arranged in sintering furnace
Conveying section, the conveying device further include: the first conveying section outside drying oven and being located at before the second conveying section is set, and setting exists
The 4th conveying section after sintering furnace and behind third conveying section.Namely the conveying device successively includes the first, second and third He
Four conveying sections.
Wherein, the conveying device includes mounting rack 410 and the delivery track 420 that is arranged on mounting rack.Described defeated
It send and is arranged at intervals at least two hangers on track, and the height of different hangers is different.
Preferably, the distance between n-th hanger and N+2 hanger and the width of liner match, and wherein N is equal to just
Integer；Preferably, the difference in height of two neighboring hanger and the length of liner match.For example, the 2nd hanger is to the 4th hanger
Between distance, can just accommodate a liner, which hangs on the 3rd hanger；And preferably, the height of the 2nd hanger
It spends suitable to the height of the 3rd hanger and the length of a liner.So that the height where the liner hung on the 2nd, 4 hanger
It is different from the height where the liner hung on the 3rd hanger.If two kinds of hangers are arranged at intervals on delivery track again, the 2nd,
Height where the liner hung on 4 hangers is identical, forms one layer of liner；The liner hung on 3rd hanger and the 2nd, 4
The height for the liner hung on hanger is different, forms another layer of liner, is thusly-formed two layers of liner.If interval is set on delivery track
Hanger there are three types of setting, then be hung with three layers of liner.
A kind of preferred embodiment, is arranged at intervals with the first hanger and the second hanger on the delivery track, and described
One, two hangers include the first linkage section 430 connecting with delivery track and the second linkage section connecting with the first linkage section
440；Wherein, second linkage section is long hook, or is formed by connecting by several sub-hooks.Specifically, such as dotted line frame in Fig. 2
Shown, the second linkage section 440 is formed by connecting by multiple sub-hooks.Preferably, first hanger includes the first linkage section and length
Hook；Second hanger includes the first linkage section and the second linkage section for being formed by connecting by several sub-hooks.In actual production,
A liner is hung on the long hook of the first hanger, a liner is hung in the sub-hook of the end of the second hanger.And according to interior
The length of gallbladder, operator can unrestricted choice sub-hook quantity, to adjust the difference in height between the first hanger and the second hanger.?
In Fig. 2, the first linkage section 430 is merely illustrated.
In a kind of specific application, the water heater liner application of slip sintered production line of the embodiment of the present invention, it is suitable for mentioning
For a kind of completely new efficient application of slip sintered production line.
The application of slip sintered production line, on the basis of above-mentioned, the number of plies of corresponding hanging liner increases drying oven and sintering furnace
Height so that drying oven and sintering furnace can be entered by being hung with the conveying device of at least double-layer inner containers；In conveying device
Three layers of liner are hung with, then the height of drying oven and sintering furnace also increases accordingly three times.
Further, since drying oven, sintering furnace height expand, and the same time enters drying oven and the liner of sintering furnace is in
Multiple increases, and correspondingly, increases the length of drying oven and sintering furnace, to guarantee to complete drying and sintering process.
Embodiment 2
The present embodiment and the technical solution of embodiment 1 are essentially identical, and the main distinction is: the hot water of the embodiment of the present invention
Device liner application of slip sintered production line, it is suitable for providing a kind of high efficiency application of slip sintered production line of old line transformation.Wherein, described
Old line transformation, is primarily referred to as being transformed the application of slip sintered production line of large capacity liner in the prior art, for example, vertical
100L or more large capacity water heater liner.
In the present embodiment, since drying oven, sintering furnace its script are to be suitable for large capacity liner, in the present embodiment
In without being transformed to drying oven and sintering furnace, need to be only arranged in conveying device according to the height of drying oven, sintering furnace and be hung
Liner the number of plies.Namely the number of plies of liner and the high-positive correlation of drying oven, sintering furnace are hung in conveying device.
Further, it uses instead from existing big liner production line as small inner container production line, hangs on a conveyor at least double
Layer liner, it is preferable that hang double-layer inner containers in the transformation of old line；Quantity into the liner of drying oven is in double increase, in order to
Guarantee drying effect, then need to lengthen the length of drying oven, and lengthening drying oven difficulty is big, cost is very high.Therefore, in this reality
It applies in example, it is preferable that as shown in Fig. 2, being additionally provided with a hot wind pipeline section 210 in the inlet of the drying oven.A kind of specific
Embodiment in, the hot wind pipeline section can be the hot air pipe of drying oven to the extended segment of drying oven Way in.
The hot wind pipeline section is arranged in immediately below the delivery track of the first conveying section, and the trend of hot wind pipeline section and first defeated
That send the delivery track of section moves towards identical.In this way, can be blown out in hot wind pipeline section in liner hanging at the first conveying section
Hot wind is dried in advance.It ensure that the drying effect of liner, and improvement cost is low, engineering is relatively easy to.
Further, in order to guarantee the drying effect of liner, improvement cost and engineering difficulty are reduced, the embodiment of the present invention is also
Conveying speed by adjusting reduction conveying device makes better effect, and the conveying speed of the conveying device is 0.8~1m/min.
