Abstract

A quick calcining device for shuttle kiln relates to the ceramic calcining technical field and adopts the following technical proposal: combustion engines are distributed on both the front and the back faces or both side faces of a kiln body cornerways; the number of the combustion engines arranged on one face is more than one. Adopting the utility model, flame encloses and heats up products along flame paths inside total kiln at fast speed without interference; meanwhile, calcining time is short and no dehiscence occurs during fast heating up from low temperature.

Description

The quick burning apparatus of shuttle kiln

Technical field:

The utility model relates to ceramic firing technology field, refers in particular to the quick burning apparatus of a kind of shuttle kiln.

Background technology:

Be used to burn the little volume shuttle kiln of ceramic, all adopt Wen's burner downward flame heat form at present, the flow process of its flame as shown in Figure 5, both sides by the kiln bottom begin, upwards, after the top arrival central authorities of arc, flow to the bottom then, discharge from chimney again, this kind structure, the flow velocity of flame are not easy to control, and there is interference in flame, non-uniform temperature in the convection heat transfer' heat-transfer by convection poor effect, kiln; Owing to be subjected to flame speed, and nozzles itself are difficult to regulate the restriction of flame temperature, firing time is generally very long, at reduction firing time more than 1250 ℃ is (not comprise cool time) more than 12 hours, oxidation firing time more than 1180 ℃ is more than 10 hours, because firing time is long, gas consumption is very big, the cost height; As improve combustion intensity and will add the temperature difference in the Dayao, cause the product cracking to increase, simple dependence improved its combustion intensity and is difficult to realize that the firing time dike shortens.

Summary of the invention:

The purpose of this utility model is to provide in a kind of kiln flame along quirk goods to be surrounded and heats, temperature is even, and flame does not exist interferences, speed fast, and firing time is lacked, and the quick burning apparatus of shuttle kiln of cracking phenomena occurs from the low temperature Shi Buhui that is rapidly heated.

The utility model is achieved by the following technical solution: the combustor diagonal angle is distributed on the two sides, front and back or two sides of kiln body, is more than one with the combustor quantity on the one side; Combustor can also be distributed on four jiaos of kiln body; The bent sub of air pipe line is connected with the inner sleeve, and interior cover joins by sealing ring and overcoat, overcoat and another bent sub; 4m ³With the combustor on the lower kiln is six, 5～8m ³Combustor on the kiln body is eight.

The utility model flame in whole kiln surrounds goods along quirk heats, and flame does not exist interferences, speed fast, and per second is up to 300 meters, and firing time is short, can be from original shortening to more than 12 hours about 5 hours as reducing glaze firing; Biscuiting can be added near 1～2 hour by original 5 hours; At low temperatures, owing to can based on quick convection current, make the interior goods thermally equivalent of kiln during low temperature by regulating air and the adjustment gas pressure be adjusted flame temperature, thereby having stopped to be rapidly heated at low temperatures causes the product cracking phenomena.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified:

Accompanying drawing 1 is the utility model front view;

Accompanying drawing 2 is the utility model vertical view;

Accompanying drawing 3 is the utility model A portion air pipe line 2 amplification views;

Accompanying drawing 4 is the quirk schematic diagram of the utility model flame;

Accompanying drawing 5 is the quirk schematic diagram of flame in the prior art kiln.

The specific embodiment:

See accompanying drawing 1,3, the utility model includes air blast 1, air pipe line 2, fuel gas pipeline 3, igniter 4, combustor 5, and air blast 1 connects air pipe line 2, and air pipe line 2, fuel gas pipeline 3, igniter 4 connect combustor 5; Combustor 5 diagonal angles are distributed on the two sides, front and back or two sides of kiln body 6, are more than one with combustor 5 quantity on the one side; Combustor 5 can also be distributed on four jiaos of kiln body 6; The bent sub 21 of air pipe line 2 is connected with interior cover 22, and interior cover 22 joins by sealing ring and overcoat 23, overcoat 23 and another bent sub 24; 4m ³With the combustor on the lower kiln 65 is six, 5～8m ³Combustor 5 on the kiln body 6 is eight.

When using the utility model, wicket 7 is opened, the goods that need burn till are put into kiln body 6, shut wicket 7, then air blast 1 is started, after the valve on the air pipe line 2 25 was opened, air was sent to combustor 5 along air pipe line 2, after the valve on the fuel gas pipeline 3 31 is opened, combustion gas (gas) enters into combustor 5 along fuel gas pipeline 3, by igniter 4 combustion gas is lighted, and makes it in combustor 5 internal combustion, flame is entered in the kiln body 6 by combustor 5, flow according to the quirk shown in the accompanying drawing 4, burned product is surrounded heat, do not have interference between flame, the flow velocity piece can be finished sintering process fast.

When its rotating shaft was rotated, overcoat 23 rotated with respect to interior cover 22, guarantees the unimpeded of air pipe line 2 at wicket 7; The intensity of flame and uniformity can also realize by the quantity of increase and decrease combustor 5.
