Abstract

The utility model relates to a multi-channel firing roller kiln, which aims to solve the problems existing in the existing multi-channel firing roller kiln of which a middle layer adopting the structure of using a carborundum beam to support a cordierite cored slab that because a thin slab has poor heat insulating property, only similar products can be burnt, the thin slab are broken, which can endanger the normal production of a lower passage, etc. The middle layer structure of the utility model is composed of a fibre folding block (2) in which a supporting beam (1) is threaded, a thin fibre layer (4), and a thin shim slab. The utility model can cause the burning of products between adjacent channels not to interfere with each other, has the advantages of ensuring one kiln to burn the same or different products, etc., and is a new kiln which is popularized.

Description

Multichannel burns till roller kilns

The utility model belongs to a kind of thin, flat goods calcination equipment, relates in particular to a kind of multichannel and burns till roller kilns.

At present, domestic production Ceramic Tiles, microcrystal glass plate etc. are thin, the calcination equipment overwhelming majority of flat goods adopts the individual layer roller kilns, because of it is compared with conventional tunnel kiln, down-draft kiln and pushed bat kiln, have light-duty, efficient, energy-conservation and are easy to outstanding advantage such as automation.People increase single kiln output in order to improve the business economic benefit, often the individual layer roller kilns are done not only widely but also long.Cause kiln operation troubles rate to increase thus, floor space strengthens, and the specific yield energy consumption is bigger, and cost increases.Along with science and technology is constantly progressive, manufacturing enterprise requires more and more higher to kiln, people have designed by burning till the roller kilns that burn till that passage forms more than two or two, it have occupation of land less, output height, low power consumption and other advantages, thereby solved a series of problems that the individual layer roller kilns exist.But the multilayer of domestic present use is burnt till the interlayer structure of roller kilns and mostly is the form that the carborundum crossbeam holds up the cordierite cored slab greatly, still exist the thin plate heat-proof quality relatively poor, each passage only can burn product of the same race, will jeopardize the shortcomings such as ordinary production of lower channel because of thin plate breaks simultaneously.

The purpose of this utility model just provides and a kind ofly product burnt till do not interfere with each other, guarantee that a kind of multichannel that the identical or different product of each passage is finished sintering process by required sintering curve burns till roller kilns.

Technical characterictic of the present utility model is: interlayer structure is made up of supporting traverse, fiber folded piece and thin backing plate etc.Perforating branches support crossbeam in the fiber folded piece, and bedding approaches backing plate thereon.Also can between fiber folded piece and thin backing plate, set up the thin fiber layer simultaneously.The thickness of fiber folded piece is as the criterion with thermal technology's calculated value of each temperature band in the kiln.

Implement that the utility model not only takes up an area of less, output height, energy consumption be low, and guarantees that each passage different product finishes sintering process by needed sintering curve, a klining becomes advantages such as various products.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model interlayer structure figure.

As shown in the figure: with build long 100 meters of kiln body, wide 2.3 meters, height be 2.5 meters bilayer to burn till roller kilns be example, this intermediate layer new structure mainly is made up of interior fiber folded piece (2), thin fiber layer (4) and the thin backing plate (3) above the fiber of wearing crossbeam (1).One in the every interval of supporting traverse (1) 0.2--0.4 rice passes fiber folded piece (2), and its material can select for use carbonization siliceous according to service conditions such as kiln temperature and width, corundum mullite rock, heat-resistance stainless steel or A3 steel pipe.Fiber folded piece (2) thickness is 260 millimeters, and thin fiber layer (4) thickness is 35 millimeters, and fibrous material can be selected for use according to the serviceability temperature difference and contain zirconium fiber or common alumina silicate fibre.Thin backing plate (3) thickness is 25 millimeters, and material can be selected clay matter, high alumina matter or cordierite for use according to the difference of serviceability temperature.

Claims

1, a kind of multichannel burns till roller kilns, it is made of kiln body, passage, nozzle, blower fan, intermediate layer, robot control system(RCS) and transmission system etc., it is characterized in that: the intermediate layer is made up of supporting traverse (1), fiber folded piece (2) and thin backing plate (3), the interior perforating branches support of described fiber folded piece (2) crossbeam (1), the thin backing plate (3) of bedding on it.

2, a kind of multichannel according to claim 1 burns till roller kilns, it is characterized in that: be provided with thin fiber layer (4) between fiber folded piece (2) and the thin backing plate (3).
