According to the present invention,, preferably adopt hereinafter the heating plate of a kind of like this structure of describing in conjunction with Fig. 3 to 14 though can adopt the heating plate 3-4 of any structure.

Each the heating plate 3-4 that expresses comprises two semi-circular portion plate 3A-3B, 4A-4B separately respectively, and these part plates mainly are adjacent to freely be supported, and this will describe later.Yet according to unshowned a kind of deformation program, clearly the many features that hereinafter will describe also can be applied to and have on many parts heating plate 3-4 of sector many parts as shown in figure 15 or an integral body.

At first, the general structure of elaboration is applicable to heating plate 3 and 4, wherein, has set forth little heating plate 3 with reference to accompanying drawing 3-4, has set forth big heating plate 4 with reference to accompanying drawing 5 to 14.

As shown in the figure, each heating plate 3-4 comprises a hollow sandwich member that is formed by plate 5-6.Each part plate 3A-3B, 4A-4B are configured on the whole circumference by lath 32 respectively separately, and lath 32 is connected to plate 5 and 6 by plumb joint.

The principal character that heating plate 3-4 and part plate 3A-3B, 4A-4B have is that they have a kind of structure with radial members, as described below like that, this radially feature can show by different way.

According to first embodiment, in the embodiment that provides, obtain described radially feature like this, promptly heating plate 3-4 is divided into some parts sector 33 diametrically, and the angle A that each part sector 33 covers preferably reaches 30 ° or littler all less than 90 °.This cuts apart intermediate space by spacer 34 and realizes.

It is all independent each other that another principal character of heating plate 3-4 is that they are useful on for the pipeline, the particularly radial circulation of each part sector 33 of thermophore radial circulation, and this feature has also disclosed radially feature simultaneously.Radial circulation is represented with arrow 35 in Fig. 4 and 6.

As previously mentioned, the inside from middle space 7 thermophore flows through the mode of each sector usually or resembles in given embodiment flows to the outside, or as a kind of flexible program, to inside, preferably the pipe section that radially extends flows from outer flow.

Shown in Fig. 4 and 6, spacer 36 preferably between plate 5 and 6, so not only influences Radial Flow, and guarantees that Radial Flow flows through the pattern of complications to obtain a more uniform heating.

Shown in Figure 11 and 12,

spacer

34 and 36 comprises the lath that is formed by single rectangle pillar, and these pillars are placed on their vertical plane.

In given embodiment, be positioned at the spacer 34 of various piece plate 3A-3B, 4A-4B lateral margin and lath 32 location in one way respectively radially, make them be positioned at or mainly be positioned at the radially

main pillar

20 and 21 tops of supporting member 16.

Shown in Fig. 4 and 6, between plate 5 and 6, also can provide additional local spacer sleeve 37.

Each part plate 3A-3B, 4A-4B have a pipeline separately respectively, and this pipeline comprises a service pipe 38 in the sandwich component current downflow at least; The distributing pipe 39 of a circle, it is near related part plate center; An opening 40, it is connected to distributing pipe 39 intermediate space 7 of sandwich component; The collecting pipe 41 of a circle, it is positioned at the excircle vicinity of part plate related on the bottom surface of sandwich component, and is connected to above-mentioned intermediate space 7 by opening 42; At least one discharge pipe 43, it is connected to circular collection pipe 41.

In the embodiment of little heating plate 3, each part that forms the intermediate space 7 of each part sector 33 is extended collecting pipes 41 until circle continuously from the distributing pipe 39 of circle.

Distributing pipe 39 and collecting pipe 41 are preferably made semicircular pipe, shown in Fig. 7 to 10 like that, be connected on the sandwich component with their planar side, so just obtain a limited total height.

From accompanying drawing, can derive aforementioned content and also be applicable to each part plate.Therefore, under the situation of using a whole heating plate 3-4, clearly manage 39-41 and may cover a complete circle but not semicircle, and can use or not use more than one service pipe 38, discharge pipe 43 separately respectively.

When firing equipment 1 operation, entering part plate 3A-3B, 4A-4B heat heating plate 3-4 respectively thereby the guiding thermophore is by service pipe 38.Therefore thermophore flows in intermediate space 7 by distributing pipe 39 and slit opening 42, from it flows to opening 42 by each part sector 33 in tortuous mode here.Through these openings 42, thermophore is collected in 41 li of collecting pipes, from it is discharged from by discharge pipe 43 here.

As mentioned above, the structure of little heating plate 3 is corresponding to big heating plate 4.Many differences between them hereinafter will be described.

First structural difference is that little heating plate 3 has less diameter.This also is the difference of the supporting member 16 of correspondence, and outer rim 44 complete obiterations of its supporting member are below heating plate 3.In fact, the supporting member 16 that is used for little heating plate 3 can be made equally with big heating plate 4, and difference only is the more close annular construction member 30 in the position of annular construction member 29.Clearance opening 45 in the processing space 2 of heating system thereby idle fully, away from supporting 17, this support 17 deviates from support frame 18.It should be noted that supporting 17 also is positioned on the lower horizontal plane in supporting member 16 belows.Opening very close to each other in heating plate 3, however in big heating plate 4 gapped really opening 9, the position of the clearance opening 46 that the position of this clearance opening 9 and supporting member 16 are interior conforms to.

Second main difference is, because there is clearance opening 9 in big heating plate 4, thereby intermediate space 7 each part sector 33 are divided into two

parts

47 and 48, and difference is that also big heating plate 4 has passage 49, and this passage 49 is connected to second portion 48 with the first 47 of above-mentioned intermediate space 7.

It should be noted that tube-in-tube structure 50 has been embedded in the center of supporting member 16 and fixed thereon, shown in Fig. 7 and 8, this tube-in-tube structure comprises a sleeve 52 with two welding beads 54, welding bead 54 is around the annular construction member 28 of part structure 24 and 25, annular construction member 28 is formed by the U-shaped pillar, and welding bead 54 is soldered to the

radially operating desk

20 and 21 of supporting member 16.Part supporting construction 24 and 25 couples together each other by the limited overlap zone 55 of size, is welded to the U-shaped part of annular construction member 28 on part-structure 24 and 25 height of separating.The locating ring 51 that is used for heating plate 3-4 is connected bead 54.

Firing equipment 1 groundwork situation hereinafter will be described.

By spreading machine 14 product to be heated is moved to above the heating plate 3-4, wherein outside edge moves this product from the centre on little heating plate 3 with a kind of known way, and moves to the centre from outer rim on big heating plate 4.In this moving process, the heating plate of this product above being positioned at drops on the next heating plate that is positioned at below it, flows through a zigzag path that runs through firing equipment 1 like this.

When work, the guiding thermophore enters circular distributing pipe 39 by each related service pipe 38, finishes intermediate space 7 by opening 40 from thermophore described here.Thermophore flows through according to above-mentioned zigzag path after the described intermediate space 7, and it leaves this space by opening 42 and is collected in the collecting pipe 41, and is discharged to as being used in the equipment of heating carrier by discharge pipe 43.

If adopt steam as thermophore, because each sector only need provide less condensed steam, this just is easy to be transformed into a kind of simple structure, and in such cases, tortuous pattern is not used in suggestion.Supply steam is removed condensate preferably by a vertical circular discharge pipe that is positioned at the center preferably by the circular distributing pipe along heating plate 3-4 excircle.

At last, should be noted that " circulation radially substantially " means that thermophore flows to the inside from the outside of each sector, or vice versa.Yet in each sector, this process is arbitrarily, needn't follow the arrow 35 of Fig. 6.

" continuous supporting member 16 " of the present invention must be understood that each supporting member extends below a heating plate 3 or 4, no matter this supporting member 16 has been made into any pattern, and do not resemble belgian patent NO.1, the special local support of describing in 013,426 on the edge.

Clearly, because ad hoc structure of the present invention, between the different parts the very big free degree is arranged, consequently effectively overcome the expansion difference, thereby in such element, particularly each heating plate 3 or 4 and each supporting member 16 in all obtains expansion uniformly, these parts can be with undesirable mode bending like this.

Can clearly be seen that also that from Figure 15 above-mentioned heating plate needn't be made up of two part plates, they also can be made up of four or more part plate.

The embodiment that above-described and accompanying drawing is represented will never limit the present invention as an example; On the contrary, such firing equipment and above-mentioned heating plate can manufacture different shape and size within the scope of the present invention.
