Description

A kind of box-like ceramic firing heating furnace group of continuous vertical array group

Technical field

The utility model belongs to ceramic-like product calcination equipment technical field, be related to a kind of continuous vertical array group it is box-like plus Hot stove group more particularly to one kind can be for such as ceramic mobile phone fuselages and backboard, ceramic switch panel, household electrical appliance ceramic plane There is plane or band to be dried along the ceramic form of structure (plate or plate band are along Thin-shell) for plate, wireless charging ceramic wafer etc. Dry, preheating, degreasing, sintering, cooling ceramic firing heating furnace group.

Background technique

Ceramic firing process contains multiple processes such as drying, preheating, degreasing, sintering, cooling, wherein degreaser drying and height Temperature sintering is the critical process link in ceramic form sintering process, can require to select according to raw material blank type and technique different Type of furnace heating furnace is once completed or substep is completed.It is burnt into production process, heating kiln provides accordingly for different process process Firing temperature, substep or the disposable firing for completing ceramic form under condition of different temperatures.

Currently, the high-temperature heater for the field mainly has intermittent and continous way two major classes both at home and abroad.It is intermittent to add Hot stove is mainly based on resistance-heated furnace, such as bell furnace, car type furnace, batch-type furnace, is chiefly used in abnormity customization ceramic form degreasing Sintering or small lot engineer testing.Continuous-type furnace is mainly based on kiln, such as tunnel oven, pushed bat kiln, push rod furnace, mesh belt Furnace etc. is chiefly used in the stable batch ceramic form firing of technical maturity, can one-time continuous realize drying, degreasing, sintering, cooling etc. Firing process process.

Batch furnace advantage be blank firing yield it is relatively high, but with technical process heating, heat preservation, cooling and people Tooling discharging process, heat energy loss is big, and production efficiency is low, causes production capacity amplification limited, and production cost cannot control effectively, It is chiefly used in realizing the firing or new product shakedown of small lot special-shaped ceramics blank.Continuous furnace should be process for stabilizing item The preferable selection for improving production capacity under part, reducing energy consumption, but application practice discovery effect in terms of product qualification rate and capacity efficiency It is also less desirable.

Different process temperature subregion is arranged in the widely applied horizontal pushed bat kiln of existing market, stove inside, and as far as possible Guarantee that each subregion thermal field is relatively stable, heat load bearing board by horizontal step-by-step system and realizes continuous production to sintering briquette part.It is this Horizontal direction stepping laser heating structural principle causes same be heated to sintering briquette part different parts to have successively, and blank is integrally heated It is asynchronous, shake vibration can be generated in the progradation of push plate push rod to sintering briquette part in addition.This asynchronous and thermal vibration of being heated Collective effect, it is easy to cause blank to generate the irrecoverable buckling deformation of initial stage of sintering, so that subsequent processing polishing operation is difficult To repair leveling, ceramic form sintering qualified rate is seriously affected.Meanwhile there are kiln collapses, arch kiln risk for pushed bat kiln, often because safeguarding not Week or improper use, kiln collapse arch kiln happen occasionally, and in addition to production pause economy is impaired, impaired furnace maintenance long processing period is taken It is very big to the production capacity and cost impact of pushed bat kiln Low fire ceramic blank with height.

Tunnel oven loads load bearing board by trolley and is run in furnace to sintering briquette part to realize firing process, can satisfy big The production requirement of batch continuous burnt, but equally there is also be heated asynchronous generation buckling deformation not to sintering briquette part different parts The problem of influencing product yield enough.In terms of energy consumption, trolley loads blank disengaging stove and completes heating, heat preservation, temperature reduction technology Process, a large amount of trolley accumulation of heats cannot be utilized effectively, and energy loss is larger, also want compared to push plate, push rod kiln comparable energy consumption It is higher by 30% or more.Push rod furnace and meshbeltfurnace, the equally common problem there is also continuous-type furnace sintering ceramic form, product The asynchronous buckling deformation yield that is heated is low, high production cost, low efficiency.Application is relatively fewer in ceramic firing industry at present, raw Production. art experience accumulation and equipment and technology level need to be improved.

It to sum up analyzes, using batch furnace and continuous furnace Low fire ceramic blank, in product yield, equipment capacity, production Cost etc. respectively has deficiency.Batch furnace does not obviously have advantage in terms of scale volume production, although horizontal continuous stove is standby The feasibility that industrial scale produces under the conditions of process for stabilizing, but the heating mode that this blank is heated during traveling, by Heat is asynchronous and thermal vibration causes buckling deformation, causes product yield low, high production cost.Especially for such as ceramic mobile phone Backboard, ceramic switch panel etc. have the ceramic form of plane or band along structure, the degreasing sintered heat treatment mode of horizontal continuous Fail the really large-scale promotion application in the industrial chain of such emerging ceramic product due to the above reasons,.
