Abstract

Aiming at the defects that the gas-fired kiln for firing Jun porcelain has the defects of slow heating speed, long firing time, waste of fuel and accelerated depletion of non-renewable energy when heating objects in the kiln, the utility model discloses a combustible multi-purpose kiln. A kind of fuel kiln, this kiln combustible with multiple fuels includes a furnace body, a fire gun for burning gas is fixed at the bottom of the furnace body; an electric heater is fixed on the side of the furnace body; There is a fuel inlet connected to the inside of the furnace body.

Description

Multi-fuel kilns

technical field

The utility model relates to an improved kiln, which belongs to a kind of kiln for industrial production, and is especially related to a kiln for firing Jun porcelain.

Background technique

In the production process of Jun porcelain, it is necessary to put the finished Jun porcelain body into a kiln for firing, and then it becomes Jun porcelain after firing. Known kilns for firing Jun porcelain are traditional kilns that use coal as fuel. The gas in the furnace body contains a large amount of comprehensive gases such as carbon monoxide and carbon dioxide during combustion of this traditional kiln that uses coal as fuel, which is beneficial to Jun porcelain is about to change, but this kind of coal-fired kiln has a complex structure and high cost, and it has been discontinued because it emits a large amount of dusty flue gas during production to pollute the environment. At present, the kiln used for firing Jun porcelain is a gas kiln burning natural gas or liquefied petroleum gas. This gas kiln includes a furnace body, and a gun for burning gas is fixed at the bottom of the furnace body. This kind of gas-fired kiln has the following defects in use: First, the flame generated by the combustion gas heats up the objects in the furnace by radiation, and the heating speed is slow, which makes it take a long time to burn Jun porcelain, wastes fuel, and is limited by the gas supply. Quality constraints; the second is that the gas burned is non-renewable energy, which accelerates the depletion of non-renewable energy.

Contents of the invention

Aiming at the defects that the gas-fired kiln for firing Jun porcelain has the defects of slow heating speed, long firing time, waste of fuel and accelerated depletion of non-renewable energy when heating objects in the kiln, the utility model discloses a combustible multi-purpose kiln. Using this kind of kiln that can burn a variety of fuels to burn Jun porcelain can not only increase the temperature quickly during firing, shorten the firing time, and improve production efficiency, but also can burn renewable energy to ensure the quality of firing Jun porcelain. quality.

For realizing the purpose of this utility model, the following technical solutions have been adopted:

A kind of kiln combustible with multiple fuels is made, the kiln combustible with multiple fuels includes a furnace body, and a musket for burning gas is fixed at the bottom of the furnace body; the utility model is that an electric heater is fixed at the side of the furnace body , A fuel inlet connected to the interior of the furnace body is provided on one side of the bottom surface of the furnace body.

The electric heater described in the utility model is a silicon carbide rod.

The utility model is characterized by simple structure and easy realization; the remarkable advantage of using the utility model is that the temperature rises quickly during firing, shortens the firing time, and improves production efficiency, and the utility model can burn renewable energy to ensure the quality of Jun porcelain.

Description of drawings

Further describe technical characterictic of the present utility model in detail below in conjunction with accompanying drawing:

The accompanying drawing is a schematic cross-sectional structure diagram of a preferred embodiment of the utility model.

In the figure: 1. Furnace body 2. Fuel inlet 3. Electric heater 4. Electric heater 5. Firearm 6. Firearm

Detailed ways

As shown in the accompanying drawings, 1 in the figure is the furnace body of the kiln, and the fire gun 5 and the fire gun 6 of the combustion gas are fixed on the bottom surface of the furnace body 1, and the fire gun 5 and the fire gun 6 are connected to the external gas supply pipeline; the utility model is An electric heater 3 and an electric heater 4 are fixed on the inner surface of the furnace body 1, and the electric heater 3 and the electric heater 4 are connected to an external power supply by wires; The fuel inlet port 2.

Because the electric heater 3 and the electric heater 4 used in the utility model are standard carbon rods that can produce far infrared rays, and the far infrared rays have a penetrating function, so the heating speed is fast when the Jun porcelain blank tire in the kiln is heated, and the burning time is shortened. Production time; when the green tire in the furnace body is fired to a certain extent and needs comprehensive gases such as carbon monoxide and carbon dioxide to generate a kiln transformation, feed firewood, crop straw and other waste materials into the furnace body 1 from the fuel inlet 2, so that it is in the furnace body 1 Carbon monoxide and carbon dioxide are generated inside, and at the same time, burning firewood, crop straw, etc. can also save electricity consumption. This kiln can be used to burn electricity or gas interchangeably, and can also burn several kinds of fuels at the same time.

Claims (2)
