At present, kieselguhr (diatom ooze) has good absorbability, so as at the aspect such as sewage disposal and purification of air
It is widely used.
The light ceramic preparation methods such as known Diatomite Ceramsite are high-temperature calcinations, using air in haydite outwardly and inwardly
Convection current making active silica-alumina composition heat up and sinter.But diatomaceous natural hole can occur in the case of higher than 800 DEG C
Cave in, apparent porosity significantly declines, lose diatomaceous absorbability.The method of existing burned diatomite haydite, which adds
Using conventional sintering modes such as coal, natural gas, coal gas or electricity more than hot mode, but there is following obvious deficiency：1st, speed is heated
Degree is slow, low production efficiency, and conventional sintering heating such as flame, hot blast, infra-red radiation etc. are all from object by heat exchange pattern
Outside is progressively heated, low production efficiency；2nd, energy-conservation and environment is not polluted, traditional sintering mostly adopts gas-combustion kiln, carbon dioxide
Discharge is big, and operating temperature is high, poor working environment.Therefore need badly in the middle of prior art and want a kind of new technical scheme to solve this
One problem.
Content of the invention
The technical problem to be solved is：A kind of vacuum light wave heating device and method is provided, in vacuum condition
Under, using light-wave irradiation Diatomite Ceramsite surface, make haydite surface obtain high temperature, sinter, improve haydite entire compression strong
While spending, the natural absorbability inside Diatomite Ceramsite, energy-conserving and environment-protective can also be retained.
A kind of vacuum light wave heating device, is characterized in that：Including hopper, seal box, metal grill transmission belt, optical wave tube with
And fan, the hopper is arranged on the top of seal box, and hopper open topped position is provided with sealing baffle, and bottom is provided with stream
Amount valve；The metal grill transmission belt and optical wave tube are arranged on the inside of seal box, and optical wave tube is arranged on metal grill transmission belt
Both sides up and down；The fan is arranged on the inside of hopper, the bottom of sealing baffle.
A kind of vacuum optical wave heating method, is characterized in that：Comprise the following steps,
Step one, the flow valve for adjusting the setting of hopper bottom, take Diatomite Ceramsite moulded pottery not yet put in a kiln to bake, are put in hopper, close hopper
The sealing baffle that top is arranged；
Step 2, start the fan that sealing baffle bottom is arranged, keep the vacuum in seal box be 0.03MPa～
0.05MPa；Start the actuating device of metal grill transmission belt, make metal grill transmission belt chatter, and laterally run successively, by silicon
Diatomaceous earth haydite moulded pottery not yet put in a kiln to bake is fallen in metal grill transmission belt from hopper, makes to be monolayer Diatomite Ceramsite mud in metal grill transmission belt
Base；
In step 3, the horizontal running of the step 2 metal grill transmission belt, it is arranged in metal grill transmission belt
The optical wave tube in portion launches 0.3 μm～3 μm of light wave, and Diatomite Ceramsite moulded pottery not yet put in a kiln to bake receives light-wave irradiation to Diatomite Ceramsite moulded pottery not yet put in a kiln to bake appearance
Face sinters；
Diatomite Ceramsite moulded pottery not yet put in a kiln to bake after step 4, step 3 outer surface sintering is run to seal box bottom, obtains silicon
Diatomaceous earth haydite.
Vacuum inside the seal box passes through fan control.
The speed that Diatomite Ceramsite moulded pottery not yet put in a kiln to bake is fallen in metal grill transmission belt from hopper in the step 2 passes through flow
Valve is controlled.
By above-mentioned design, the present invention can bring following beneficial effect：A kind of vacuum light wave heating device and side
Method, under vacuum, using light-wave irradiation haydite surface, makes haydite surface obtain high temperature, sinters, improve haydite entirety
While comprcssive strength, the natural absorbability inside Diatomite Ceramsite, energy-conserving and environment-protective can also be retained.Arrange at sealing baffle
Fan, can both maintain the vacuum in seal box, haydite can have been preheated again；Diatomite Ceramsite can be subject to uniformity
Optical wave heating, causes haydite appearance to be sintered, and remains stationary inside haydite, the gas in vacuum inside haydite
Haydite is extracted, so as to maintain the unobstructed of Diatomite Ceramsite natural hole；Haydite is allowed to obtain the same of certain mechanical strength
When keep larger absorbability.
