Description

Electric burner for coal stove

The utility model relates to a kind of apparatus that utilizes electric energy to make coal combustion, and this apparatus is applicable to the soft coal fire.

People mainly light a fire with coal now, and people are many during the soft coal fire makes fire-lighter with charcoal and plant.So both inconvenient, be unfavorable for protecting environment again.People utilize timber to make charcoal can damage forest, and people burn plant and are unfavorable for protecting vegetation.Utilize plant to light a fire and also can produce the people's that chokes smog.After a certain amount of charcoal or plant are used for igniting, be converted into other materials, can not repeatedly be used for lighting a fire.Present electric calorifie installation, as electric furnace, hair dryer, electric fan etc., its purposes is not lit a fire.

In view of the foregoing the utility model provides a kind of protection ring border that both helped to society, can repeatedly be used for lighting a fire the apparatus that brings convenience to people again.The heater of this apparatus can make coal combustion after the energising, because the temperature that it produces surpasses the burning-point of coal.Alternative charcoal and plant of this apparatus when lighting a fire as fire-lighter.

The utility model is achieved in that the refractory thermal insulator of making definite shape with refractory material.Refractory thermal insulator comprises two parts: top wraps in section lead outside, and the bottom is used for fixing heater.The top of refractory thermal insulator is hollow, is convenient to lead and therefrom passes.Bossing is arranged at the bottom of refractory thermal insulator, and the part between the bossing is a sunk part.Heater is fixed in sunk part, and is subjected to the protection of bossing, and it can not damaged by coal when lighting a fire.The length of refractory thermal insulator is 40-140 centimetre, the bottom of refractory thermal insulator, promptly fixedly the long 5-50 of the part of heater centimetre.The girth of refractory thermal insulator upper and lower is counted as the length that a line of tightening centers on one week of upper and lower of refractory thermal insulator, and then the girth on refractory thermal insulator top is 2-20 centimetre, and the girth of bottom is 10-40 centimetre.Refractory thermal insulator ability stove fire high temperature, it breaks at the Shi Buhui that lights a fire, and excellent electric insulating is arranged.Lead in the refractory thermal insulator is a two-wire.The fusing point of this section lead surpasses 900 ℃, and it can not fuse when lighting a fire.The upper end of this section lead links to each other with the common insulated wire that has plug, and the lower end of this section lead links to each other with the two ends of heater.Like this, with plug insertion socket, just form closed circuit.Heater is can generate heat after the energising to producing the device of high temperature.Heater and refractory thermal insulator bottom constitute heating part of the present utility model.The burning-point of coal is 400-500 ℃, and behind the connection power supply, the temperature that heater produces surpasses the burning-point of coal, so the heating physical efficiency makes coal combustion.

The utility model has the advantages that: the related apparatus of the utility model utilizes electric energy as the energy of lighting a fire, and can repeatedly be used for lighting a fire; Use this apparatus can reduce the trouble that people light a fire and run into, bring convenience, and help protecting environment to people; This apparatus structure is simple, and is with low cost.

Embodiment:

Two parts of refractory thermal insulator of the present utility model (as Fig. 1), i.e. fixedly part of heater (7) and the inner part (3) that a section lead is arranged, preferably directly one-tenth is as a whole, and does not use the linking part.Fixedly the part of heater (7) is preferably made gear-like (as Fig. 1, Fig. 2), and fin (5) and groove (6) are arranged above.Fin between two tie points of lead (2) and heater (4) can not have the breach, and there is a breach upper end or the lower end of all the other each fins (5).Adjacent two fins, one breach is in the upper end, and another breach is in the lower end.Heater (4) is fixed on the refractory thermal insulator by groove (6) and breach successively tortuously.Heater (4) is fixed on groove (6) lining, is subjected to the protection of fin (5).In order to make heater (4) from top to bottom by each bar groove (6), the groove number becomes even number.It is hollow that there is the part (3) of a section lead inside of refractory thermal insulator, is convenient to this section lead (2) and therefrom passes.This section lead (2) is a two-wire, and it is fused at the Shi Buhui that lights a fire.This section lead (2) both linked to each other with the two ends of heater (4), and (as Fig. 1) links to each other with the common insulated wire (1) that has plug again.Common insulated wire (1) also is a two-wire.Like this, with plug insertion socket, just form closed circuit.There is the part (3) of a section lead inside of refractory thermal insulator, (as Fig. 1) that its top is preferably crooked, and stove fire can not baked bad common insulated wire (1) when lighting a fire like this; Round platform (as Fig. 1, Fig. 2) is preferably made in its underpart, and gleed can not be attached to the round platform surface when taking out ignition electrical equipment like this.Refractory thermal insulator of the present utility model is the electric insulation goods of porcelain system preferably, and the used heater of the utility model (4) is nichrome wire preferably.Heater (4) is fixed, the two ends of heater (4) and the lower end of refractory thermal insulator inside conductor (2) are linked to each other, the upper end of common insulated wire (1) that has plug and refractory thermal insulator inside conductor (2) is linked to each other, so just made an ignition electrical equipment (as Fig. 1).During use, the heating part of ignition electrical equipment is stretched in the stove, put into more tiny particulate coal grain, plug insertion socket is connected power supply, heater (4) begins to make coal combustion.When treating that coal can spontaneous combustion, extract plug earlier out, from stove fire, take out again and get angry electrical equipment.Such stove fire has just taken fire.
