Abstract
The utility model discloses a gas heating device for a voltage dependent resistor spray granulator. The gas heating device is mainly characterized in that the gas heating device for the voltage dependent resistor spray granulator comprises a gas generating furnace, a pipeline, an exhaust fan, a controller and a burner; the gas generated by the gas generating furnace is connected with the controller by the pipeline, and enters into the burner to be burned through the pipeline by the means that the flow quantity is controlled by the controller, and the generated heat energy is transported into an air inlet pipeline of the spray granulator by the exhaust fan; and a temperature signal is transmitted to the controller by a temperature sensor arranged above the air inlet pipeline of the spray granulator, and the air inlet quantity of the gas is automatically adjusted by the controller according to the temperature signal. The gas heating device is replaced by an electric heating element to be heated, so that the uselessness phenomenon since a resistor disc has foams or holes caused by the short circuit of the electric heating element can be avoided, and 60% of the production cost in the production of the working procedure can be further directly reduced.
Description
Technical field
The utility model belongs to the Granulation Equipments technical field, relates to the Granulation Equipments that uses in the piezoresistive wafer manufacture craft process, is specifically related to a kind of sponging granulator coal gas heater.
Background technology
Mist projection granulating adopts the effect of spray dryer by means of atomizing and heat exactly, makes the method for the dry powder of solvent evaporation acquisition in the slurry droplet.Spray-drying process is exactly that slurry makes slurry drip the process that rapid oven dry becomes the particle powder through atomizer.Spray-drying is extensive use in traditional ceramics, organic and inorganic chemical industry, powder metallurgy, food, medical industry not only, and in various hyundai electronicses, function ceramics industry, has been used widely.Spray-drying become modern oxide ceramics prepared composition evenly, the dry-pressing blank density is even, the requisite important process measure of original paper of obtained performance uniformity number.
At present, most of sponging granulators adopt the heating heat supply, the insulation of inorganic insulation powder, the U type structures of stainless steel outer packed pipe of adopting in this element more.Because element is bad or limited service life in crudy, often when the spray-drying operation, temperature does not reach setting, adopts and finds that some element explosion causes short circuit.These iron tramps that dissolve because of short circuit are brought in the material with hot blast, can cause resistor disc generation foaming or hole and scrap.Will often dismantle heating in the course of the work and check and change, the dismounting maintenance is inconvenient.Sponging granulator is big with heating heating energy consumption, and product cost is high.
Summary of the invention
For solving the problems of the technologies described above, the utility model purpose provides a kind of piezo-resistance sponging granulator coal gas heater.
For achieving the above object, the technical scheme that the utility model is taked is that this sponging granulator coal gas heater comprises gas generator, pipeline, air exhauster, controller and burner; The coal gas that gas generator produces is connected on the controller through piping, and coal gas gets in the burner through pipeline through controller control flow and burns, and the heat of generation is transported to the intake stack of sponging granulator through air exhauster; The temperature sensor of sponging granulator intake stack top is sent to controller with temperature signal, and controller is regulated the air inflow of coal gas automatically according to temperature signal.
Said air exhauster adopts the high temperature resistant stainless steel blower fan.
The utility model adopts the beneficial effect of technique scheme to be: replace the heating heating through the coal gas heater; The phenomenon of not only having avoided the heating short circuit to cause resistor disc generation foaming or hole and having scrapped, and more directly reduced by 40% production cost of producing in this operation.
Description of drawings
Below in conjunction with accompanying drawing the structure of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Like Fig. 1, the said sponging granulator coal gas of the utility model heater comprises gas generator 7, pipeline 2, air exhauster 4, controller 1 and burner 3; The coal gas that gas generator 7 produces is through being connected on the controller 1, and coal gas gets into burning in the burner 3 through controller control flow through pipeline 2, and the heat of generation is transported to the intake stack 5 of sponging granulator through air exhauster 4; The temperature sensor 6 of sponging granulator intake stack top is sent to controller 1 with temperature signal, and controller 1 is regulated the air inflow of coal gas automatically according to temperature signal.
Said air exhauster adopts the high temperature resistant stainless steel blower fan.
Said controller adopts temperature indicator and gas flow controller.
