Abstract

The utility model relates to a novel kiln furnace which adopts waste heat and naked flame to fire products; a silicon plate is arranged in the kiln furnace; an inner cavity of the kiln furnace is divided into an upper cavity chamber and a lower cavity chamber by the silicon plate; a firing product transmission device is arranged above the upper cavity chamber of the kiln furnace; the left side and the right side positioned below the firing product transmission device are provided with two rows of combustion nozzles; a burning chamber is arranged in the lower cavity chamber of the kiln furnace; the kiln furnace is also provided with a blower connected with a tail gas discharge port of the burning chamber of the kiln furnace; an outlet of the blower is connected with the combustion nozzle through an air pipe; the combustion nozzle is connected with a gas burning transportation pipe. Due to the full utilization of the waste heat of the tail gas of the kiln furnace, the novel kiln furnace reduces burning consumption at one side, is favourable for controlling firing temperature in different states at the other side, and enhances the product quality.

Description

Adopt waste heat and the dual novel kiln of firing product of naked light

Technical field

The utility model relates to Industrial Stoves, particularly the roll shaft kiln of architecture advances and the improved firing ceramics of method for cooking.

Background technology

At present, industrial firing ceramics often adopts roll shaft kiln (in addition, also having tunnel cave and shuttle kiln etc.).

Known coal firing (or heating gas kiln) is only conducted heat every cigarette with the silicon plate and is fired product, its weak point is, fire just individual layer burning with the silicon plate every cigarette, the temperature instability, the bad control of product quality, flue is extracted the waste heat that goes out and is not used, the product that conducts heat and to fire every cigarette, be subjected to the restriction of raw material quality and prescription, cause product base substrate rubicundity, jaundice,, just must improve the quality of raw material and adjust prescription if make product base substrate color reach Bluish white, so just increase product cost, also reduced product market competitiveness.

The utility model content

The purpose of this utility model is at prior art problems and weak point and improve a kind of waste heat and dual novel kiln of firing product of naked light of adopting, to make full use of the kiln using waste heat from tail gas, to reduce fuel consumption, make easy temperature control system when firing, more stable simultaneously, thereby improve the quality of products.

This novel purpose is such realization: a kind of waste heat and dual novel kiln of firing product of naked light of adopting, comprise kiln, and the transmission device of firing is provided with a silicon plate in the kiln, and the silicon plate is divided into upper and lower two chambers with the kiln inner chamber; Described burned product transmission device is arranged on kiln upper chamber top, is positioned at its below and arranged on left and right sides and is provided with two row's burners, and the kiln bottom chamber is provided with the combustion chamber; Also have the blower fan that is connected with kiln combustion chamber exhaust port, the blower fan outlet is connected with burner through airduct, and burner is connected with the gas combustion carrier pipe simultaneously.

Above-mentioned kiln bottom chamber also is provided with preheating zone and heat-radiation belt.

Above-mentioned airduct is provided with proportioning valve.

This novel kiln is to be that the basis is improved and formed with existing roll shaft kiln.The burner hearth of original kiln can be divided into preheating zone (being preheating chamber), combustion chamber (being high temperate zone) and heat-radiation belt (being heat dissipation chamber) as lower chambers, it is separated installation burner in the upper chamber and burned product transmission device (being live-roller) with the silicon plate.Lower chambers is as the burner hearth heating part, and coal-fired heat is as the main thermal source of firing.Simultaneously, introduce burner hearth tail gas and combustion air through burner, and be equipped with proportion of gas fuel, burn as natural gas, coal gas or liquefied gas etc.

Compared with prior art, this novel beneficial effect is:

1, makes full use of the kiln using waste heat from tail gas, reduced the fuel consumption level

General nearly 1000～1200 ℃ of fire box's temperature, the discharge tail gas temperature can reach 200～500 ℃, in gaseous fuel, be equipped with kiln tail gas in right amount, can satisfy the needs of oxidizing fire stage (allocation ratio is little) and the different processing temperatures of reduction combustion phases (allocation ratio is big) respectively, and after product burns till, strengthen the combustion air allocation ratio, reach the requirement of rapid quench cooling.

2, the temperature that product is fired is more easy to control, and temperature is more stable

Product is fired main thermal source and is produced by fire coal, its heat imports in the kiln upper chamber by the silicon plate, burned product is heated, simultaneously, gaseous fuel and the tail gas of introducing certain proportioning by burner directly adopt naked light to heat, be convenient to control technological temperature on producing, simultaneous temperature is easier to be stabilized in the scope of requirement.

3, firing product quality is improved

Conduct heat and be aided with naked light by the silicon plate and fire, burned product is heated evenly and unlikely distortion and produce waster.What adopt different proportionings is that to be equipped with combustion air be tail gas to gaseous fuel, it is applied in the stage is fired in oxidation and the stage is fired in reduction, realize control easily to two phase temperature, but fast cooling after ceramic burns till, reduce product cracking and distortion, the product base substrate color that burns out is bluish white, has improved product quality.

The utility model adopts pluralities of fuel to fire product, and cost of investment is low, and the raw material range of choice is wide, and technology is simple, but production plurality of specifications product.Product base substrate color uniqueness, the market sale potentiality are big.

The specific embodiment

Fig. 1 Fig. 2 illustrates, and this novel kiln 1 and burned product transmission device 7 (live-roller) of comprising is provided with a silicon plate 6 in the kiln 1, and the silicon plate is divided into upper and lower two chambers with the kiln inner chamber; Burned product transmission device 7 is arranged on kiln 1 upper chamber top, is positioned at its below and arranged on left and right sides and is provided with two row's burners 3, and kiln 1 bottom chamber is provided with and preheating zone 10, combustion chamber 9 and heat-radiation belt 8; Also have the blower fan 5 that is connected with kiln 1 combustion chamber exhaust port, blower fan 5 outlets are connected with burner 3 through (combustion-supporting) airduct 4, and burner 3 is connected with gaseous fuel carrier pipe 2 simultaneously.Burner is introduced gaseous fuel when introducing burner hearth tail gas and combustion air.On (combustion-supporting) airduct 4 proportioning valve is set, with the proportioning of measure control tail gas and gaseous fuel.

Burner is installed in the product lower floor of kiln preheating zone, high temperate zone (combustion chamber), heat-radiation belt respectively, can decide burner that quantity is installed according to kiln length, width.
