Abstract
The utility model discloses an alundum pipe high-temperature rotary furnace, which comprises a furnace pipe structure and a heating device arranged outside the furnace pipe structure, wherein the furnace pipe structure is a double-layer furnace pipe structure, the outer layer is a round alundum pipe, and the inner layer is an alundum furnace liner. The alundum furnace liner is adopted, so the heat resistance performance of the rotary furnace is very good, in addition, the alundum furnace linear is of an edge cone collecting structure, pipe plugs are added at the two ends, the materials are enabled to only exist in the conical alundum furnace linear, and the heating effect is good.
Description
Technical field
The utility model relates to a kind of alundum tube high temperature rotating stove, relates in particular to a kind of alundum tube high temperature rotating stove that temperature is high and be able to bear strong corrosion, cooling velocity is fast that requires.
Background technology
At present conventional high temperature rotating stove flue is heat-resisting alloy pipe, general external diameter is little tens millimeters large several meters tens meters, 1300 ℃ of the upper limit temperature of heat tolerance theoretical temperatures, the highest resistance to 1100 ℃ of high temperature of actual serviceability temperature.
Because rotary furnace is rotation, calcination product under current intelligence, product sintering evenly, caking less, calcining fully can enhance product performance greatly.
And at present heatproof degree the highest can be resistance to 1700 ℃ be alundum tube, but the high-temperature corundum pipe kiln of seeing on the market mostly at present is Static Calcination tube furnace.This boiler tube is that a straight tube is calcined in static environment, and in order to guarantee that high-temperature region temperature homogeneity is good, two mouth of pipe is plugged with corundum pipe plug.If rotate calcining because alundum tube is straight tube, product easily flow to the non-thermal treatment zone, causes portioned product raw burn, and discharging is mixed into and in normal product, reduces properties of product.Therefore present tube furnace is on the market all Static Calcination pattern.
Utility model content
The utility model, in view of above reason, has been invented the alundum tube high temperature rotating stove of 1700 ℃ of a kind of heatproof degree, consists of, to overcome above-mentioned technical problem corundum flue.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
An alundum tube high temperature rotating stove, comprising: furnace tube structure and be located at the heater outside furnace tube structure, and wherein, furnace tube structure is double-deck furnace tubular construction, and skin is circular alundum tube, and internal layer is corundum flue.
Further, preferred structure is that described corundum flue is that wimble structure is received at edge, and increases pipe plug at two ends.
Further, preferred structure is that described pipe plug is ceramic pipe plug, and is located at the heating region of alundum tube high temperature rotating stove and the changeover portion of non-heating region.
Further, preferred structure is that the heater of described alundum tube high temperature rotating stove, for heating casing, is movable retractable structure.
After the utility model has been taked such scheme, owing to having taked corundum flue, so its heat resistance is very good; And corundum flue is that wimble structure is received at edge, increases pipe plug at two ends, has guaranteed that thus material only can be present in taper corundum flue, and heating effect is good.
Other features and advantages of the utility model will be set forth in the following description, and, partly from description, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in the description write, claims and accompanying drawing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the structural representation of the utility model alundum tube high temperature rotating stove;
Fig. 2 is the structural representation of the furnace tube structure of the utility model alundum tube high temperature rotating stove;
Fig. 3 is the structural representation of the furnace tube structure of the utility model alundum tube high temperature rotating stove;
Fig. 4 is the opening-closing structure schematic diagram of the utility model alundum tube high temperature rotating stove;
Wherein, Reference numeral: 1. alundum tube, 2. corundum flue, 3. pipe plug.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
As shown in Figure 1, the utility model alundum tube high temperature rotating stove, it mainly includes furnace tube structure and is located at the heater outside furnace tube structure, wherein, furnace tube structure is double-deck furnace tubular construction, and its skin is circular alundum tube 1, its internal layer is corundum flue 2, and described corundum flue 2 is edge receipts wimble structure, and increases pipe plug 3 at two ends.
Owing to having taked corundum flue, so its heat resistance is very good; And corundum flue is that wimble structure is received at edge, increases pipe plug at two ends, has guaranteed that thus material only can be present in taper corundum flue, and heating effect is good.
As shown in Figure 2,3, described pipe plug 3 is ceramic pipe plug, and is located at the heating region of alundum tube high temperature rotating stove and the changeover portion of non-heating region.
Thus, alundum tube 1 drives inner corundum flue 2 to rotate together in rotation process, because having the cone of receipts effect so material, corundum flue two only can be present in taper corundum flue, and can not cross cone mouth, do not move to non-heating region, simultaneously in order to guarantee that receive cone corundum flue can not move to non-heating region in boiler tube rotation process, therefore receiving cone corundum flue both sides has ceramic pipe plug, to guarantee the boiler tube high-temperature heating region that all mediates in whole rotation sintering process.
Wherein, as shown in Figure 4, the heater of described alundum tube high temperature rotating stove is heating casing, and it is that movable open is box-like, can open at any time burner hearth to make whole boiler tube exposed in air, and cooling rate is more quick.Can conveniently take off simultaneously remove and install, feed in raw material, discharging.
The utility model is taking the beneficial effect having after technique scheme as below:
The first, because the furnace tube material of described corundum rotary furnace is that the high-temperature resistant degree of corundum material can reach 1700 ℃, alundum tube can guarantee product cleannes simultaneously.
The second, because thermal treatment zone corundum flue receipts cone effect in the boiler tube of described corundum rotary furnace can guarantee that material operation only can be in the corundum flue of receipts cone.
Three, because corundum is received the ceramic pipe plug that there is filling on cone flue both sides, also limit corundum simultaneously and received the not meeting left and right skew in boiler tube rotation process of cone flue, remain at high-temperature heating region.
Four, can folding due to the casing of described tube furnace, so just can greatly shorten the temperature fall time after sintering, can conveniently take off that corundum furnace tube removes and installs, feeds in raw material, discharging simultaneously.Can meet different product technological requirement.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
