Abstract
The utility model provides a kind of sintering oven residual neat recovering system; it includes sintering oven, sponging granulator, Stainless Steel Coil and air blower; the Stainless Steel Coil bending is wrapped on the kiln wall of the sintering oven; one end of the Stainless Steel Coil is connected with the air blower, and the other end of the Stainless Steel Coil is connected with the heating unit of the sponging granulator.The utility model is simple in structure, easy to implement, and the waste heat on sintering oven can be easily introduced in sponging granulator by it, so as to reduce the electric quantity consumption of sponging granulator, eventually reduces the production cost of piezoceramic material.
Description
Technical Field
The utility model relates to a waste heat recovery system, especially a sintering kiln waste heat recovery system.
Background
The preparation process of the piezoelectric ceramic material roughly comprises the following steps: proportioning, presintering, ball milling, spray granulation, molding, plastic removal and sintering.
Wherein, the spray granulation process needs to use a spray granulator, and when the spray granulator carries out spray granulation, the temperature in a spray granulation cavity of the spray granulator needs to reach more than 150 ℃. Since the internal space of the spray granulation chamber is large, the amount of electricity consumed by the spray granulator is very large in order to maintain a high-temperature environment. On the other hand, the sintering step requires the use of a sintering kiln. During sintering, the temperature in the sintering kiln reaches 1100 ℃ to 1360 ℃, and a large amount of waste heat is radiated on the kiln wall of the sintering kiln.
If the waste heat on the sintering kiln can be introduced into the spray granulator, the power consumption of the spray granulator can be effectively reduced, and the production cost is reduced.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model provides a sintering kiln waste heat recovery system, its technical scheme as follows:
the utility model provides a sintering kiln waste heat recovery system, its includes sintering kiln, spray granulator, stainless steel coil pipe and air-blower, the winding of buckling of stainless steel coil pipe is in on the kiln wall of sintering kiln, the one end of stainless steel coil pipe with the air-blower intercommunication, the other end of stainless steel coil pipe with spray granulator's heating device intercommunication.
In a specific embodiment, the outer wall of the stainless steel coil is coated with a heat insulation layer.
The utility model discloses simple structure, implementation convenience, it can conveniently introduce the waste heat on the sintering kiln to the spray granulator in to reduce the power consumption of spray granulator, finally reduced piezoceramics material's manufacturing cost.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings which are needed in the embodiments and are practical will be briefly described below and will be obvious, the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts. Wherein,
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the waste heat recovery system of the sintering furnace provided by the present invention comprises a sintering kiln 1, a spray granulator 2, a stainless steel coil 4 and a blower 5. The stainless steel coil 4 is bent and wound on the kiln wall of the sintering kiln 1, one end of the stainless steel coil 4 is communicated with the blower 5, and the other end of the stainless steel coil 4 is communicated with the heating device 3 of the spray granulator 2 on the kiln wall.
When piezoceramics material production is carried out, start air-blower 5, the air current flows to spray granulator 2 through stainless steel coil 4 constantly, carries the waste heat on the kiln wall of sintering kiln 1 to spray granulator 2 in the heating device 3 simultaneously to the realization is to the heating in spray granulator 2's spray granulation chamber, and the electric quantity consumption of spray granulator has finally been reduced, has reduced manufacturing cost.
Preferably, in order to reduce heat loss, the outer wall of the stainless steel coil 4 is coated with a heat insulation layer.
The invention has been described above with a certain degree of particularity and detail. It will be understood by those of ordinary skill in the art that the description of the embodiments is merely exemplary and that all changes that may be made without departing from the true spirit and scope of the present invention are intended to be within the scope of the present invention. The scope of the invention is defined by the appended claims rather than by the foregoing description of the embodiments.
