Summary of the invention
Technical problem to be solved by this invention is: provide a kind of vacuum light wave heating device and method, under vacuum, utilize light-wave irradiation Diatomite Ceramsite surface, haydite surface is made to obtain high temperature, sinter, while improving haydite entire compression intensity, the natural adsorption capacity of Diatomite Ceramsite inside can also be retained, energy-conserving and environment-protective.
A kind of vacuum light wave heating device, it is characterized in that: comprise hopper, seal box, metal grill transport tape, optical wave tube and fan, described hopper is arranged on the top of seal box, hopper open topped position is provided with sealing baffle, and bottom is provided with flow valve; Described metal grill transport tape and optical wave tube are arranged on the inside of seal box, and optical wave tube is arranged on the both sides up and down of metal grill transport tape; Described 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 regulating hopper bottom to arrange, get Diatomite Ceramsite moulded pottery not yet put in a kiln to bake, put into hopper, close the sealing baffle that hopper top is arranged;
The fan that step 2, startup sealing baffle bottom are arranged, keeps the vacuum in seal box to be 0.03MPa ~ 0.05MPa; Start the transmission device of metal grill transport tape, make metal grill transport tape chatter, and laterally run successively, Diatomite Ceramsite moulded pottery not yet put in a kiln to bake is fallen on metal grill transport tape from hopper, make metal grill transport tape to be individual layer Diatomite Ceramsite moulded pottery not yet put in a kiln to bake;
In the horizontal running of step 3, described step 2 metal grill transport tape, the optical wave tube being arranged on metal grill transport tape top launches the light wave of 0.3 μm ~ 3 μm, and Diatomite Ceramsite moulded pottery not yet put in a kiln to bake accepts light-wave irradiation and sinters to Diatomite Ceramsite moulded pottery not yet put in a kiln to bake outer surface;
Diatomite Ceramsite moulded pottery not yet put in a kiln to bake after step 4, described step 3 outer surface sintering moves to bottom seal box, obtains Diatomite Ceramsite.
Described seal box inside vacuum pass through fan control.
The speed that in described step 2, Diatomite Ceramsite moulded pottery not yet put in a kiln to bake falls on metal grill transport tape from hopper is controlled by flow valve.
By above-mentioned design, the present invention can bring following beneficial effect: a kind of vacuum light wave heating device and method, under vacuum, utilize light-wave irradiation haydite surface, make haydite surface obtain high temperature, sinter, while improving haydite entire compression intensity, the natural adsorption capacity of Diatomite Ceramsite inside can also be retained, energy-conserving and environment-protective.The fan that sealing baffle place is arranged, both can maintain the vacuum in seal box, again can preheating haydite; Diatomite Ceramsite can be subject to optical wave heating uniformity, causes haydite appearance to be sintered, and haydite inner sustain original state, in vacuum, the gas of haydite inside is also drawn out of haydite, thus maintains the unobstructed of Diatomite Ceramsite natural hole; Haydite is allowed to keep larger adsorption capacity while obtaining certain mechanical strength.
