Description
Technical field
High-temperature sintering apparatus field of the present invention, more particularly to a kind of dual system cooling kiln.
Background technology
The major way of kiln cooling has：Natural cooling, circulating water and unlatching furnace ventilation cooling, ordinary circumstance
Under, as temperature is reduced, the speed of kiln cooling can be more and more slower.Such as：The lower natural cooling of temperature, is typically cooled to from 1500 DEG C
1000 DEG C need 5-10 hour, and being cooled to 200 DEG C from 1000 DEG C needs 20-30 hour.
Assuming that room temperature is 25 DEG C, it is below the contrast of three kinds of cooling methods：
Natural cooling：Kiln in temperature-fall period not by any other mode, natural cooling at room temperature.Advantage is：
To the less demanding of burner hearth material, overall cost is relatively low.Have the disadvantage：Production cycle is long, and efficiency is low.
Circulating water：Catch basin is cast by equipment, cooling water pipe is wound in kiln surrounding, is used in temperature-fall period
Compressor keeps cooling water to keep low temperature, and kiln temperature is reduced by thermaltransmission mode.Advantage is：Cooling rate is fast, and water temperature can
Regulation and control.Shortcoming：High is required to sealed cooling water system, to keep water circulation system stable, it may be necessary to be spy to cooling water
Different processing, requires high to the thermal shock resistance of burner hearth material.
Ventilating and cooling：At ambient temperature, accelerate the flowing of burner hearth inner periphery air, make stove using the principle of heat radiation
Thorax cools.Advantage：Cooling rate is fast, and temperature-fall period is gentle, not high to burner hearth material requirements.Shortcoming：Structure is with respect to above two
Mode is complicated, requires high in manufacture and automatically controlled aspect.
Therefore, how preferably to shorten cool time, the not high equipment of burner hearth material requirements can at present be explored again
Direction.
The content of the invention
The purpose of the present invention is to be directed to the problem of being run into existing production there is provided a kind of dual system cooling kiln, by focus
Focusing on needs time most long cooling link, designs the ventilating system of kiln, accelerates the air flow rate of burner hearth surrounding, contracting
Short temperature fall time.
To realize object above, the technical scheme is that：
A kind of dual system cooling kiln, including the ventilator hood connected at the top of cabinet shell and cabinet shell, in addition to water
Cooling system and ventilation unit, cabinet shell bottom connection plenum partitions, plenum partitions lower end connection water-cooling system, water-cooling system week
Enclose provided with ventilation unit.
The cooling fan that the ventilation unit includes ventilation skirt and is fixed on ventilation skirt four edges.
Heating element heater is provided with the cabinet shell, the space of the heating element heater composition is burner hearth main body.
Outwards corresponding cabinet shell is provided with the hearth door for being used for closing air-flow environment to the burner hearth main body.
Certain gap is provided between the cabinet shell and heating element heater, the gap is ventilation gap.
The water-cooling system is that S type cooling water pipes are connected up on plenum partitions.
The quantity of cooling fan is 2-20.
The beneficial effects of the invention are as follows：
The temperature fall time of burner hearth can substantially be shortened, it is interval interior from 1000 DEG C -200 DEG C of coolings, 40%-70% can be shortened
Time, hence it is evident that improve production efficiency.
The present invention design principle be：Water-cooling system and the advantage of air cooling system are combined, adds and divulges information in burner hearth bottom
System so that burner hearth bottom produces malleation, air-flow is moved up, and heat exchange occurs for air-flow and burner hearth in the process, reduces stove
Bore temperature, last air-flow is discharged by the ventilator hood at top, in the malleation space of kiln bottom, disposes water circulation system,
Under normal circumstances, water temperature is equal to room temperature, if any special requirement, can carry out cooling processing to cooling water to reach preferable cooling
Effect.

Embodiment
One embodiment of the present invention is further illustrated with reference to the accompanying drawings.
Embodiment 1：A kind of dual system cooling kiln, including cabinet shell 3 and the ventilator hood of the top of cabinet shell 3 connection
1, in addition to water-cooling system 5 and ventilation unit, the bottom of cabinet shell 3 connection plenum partitions 4, the lower end of plenum partitions 4 connection water cooling
Around system 5, water-cooling system 5 and bottom is provided with ventilation unit.
The cooling fan 7 that the ventilation unit includes ventilation skirt 6 and is fixed on the ventilation four edges of skirt 6.
Heating element heater 9 is provided with the cabinet shell 3, the space that the heating element heater 9 is constituted is burner hearth main body 2.
Outwards corresponding cabinet shell 3 is provided with the hearth door 8 for being used for closing air-flow environment to the burner hearth main body 2.
Certain gap is provided between the cabinet shell 3 and heating element heater 9, the gap is ventilation gap 10.
The water-cooling system 5 is that S type cooling water pipes are connected up on plenum partitions.
The quantity of cooling fan is 2-20.
The present invention workflow be：
1st, when kiln drops to 1000 DEG C or so, water-cooling system starts, first the temperature of reduction ventilation train of dress inner air.
Cooling water system suggestion uses copper tubing, and cooling water pipe is fixed on discord burner hearth body contact on plenum partitions.2nd, wind is cooled down
Fan starts, and fan is equipped with four sides, keeps producing pressure-fired inside radiating train of dress, makes air flows upwards.3rd, in cooling train of dress
The air of interior cooling, the peripheral clearance of burner hearth main body is flowed through by plenum partitions, wraps up burner hearth main body.4th, cooling air passes through stove
After thorax main body, discharged by ventilator hood.
