Abstract

(57) [Summary] [Purpose] To provide a fire lane type batch kiln that allows easy foundation work, low construction costs, and allows for stable firing similar to conventional ones. [Configuration] The burner speed is 10 m/sec at the upper part of one wall 5 of the furnace body 1 and at the lower part of the opposing wall 7.
The high-speed burners 6 and 7 described above are installed to form a high-speed swirling flow in a vertical plane within the furnace. Further, an exhaust port 9 with a damper 10 is formed in the ceiling of the furnace body 1, and exhaust is exhausted from the top. The kinetic energy of the high-speed swirling flow outweighs the influence of gravity, so
Even if the air is exhausted from the top, the flow velocity distribution will not be disturbed.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the improvement of batch kilns used for firing various ceramic products. In particular, it relates to improvements to fire lane batch kilns.

0002

[Conventional technology]

Burners are installed at the top of one wall of the furnace body and at the bottom of the opposite wall. This is a method in which firing is carried out by attaching a The furnace is known as a fire lane batch kiln.

0003 In such a conventional general fire lane batch kiln, 1 to 5 A burner with a burner speed of about m/sec is used, and a gentle swirling flow is used. is formed in the furnace, so the exhaust port is located at the bottom of the furnace body in consideration of the flow velocity distribution of the swirling flow. It was common practice for the system to be installed under the floor and exhaust air from under the floor using an exhaust fan. But this Batch kilns, which exhaust air from under the floor of the sea urchin furnace, are not easy to do foundation work at the time of construction. However, the disadvantage was that the construction period was long and the construction cost was high.

0004

[Problem that the idea aims to solve]

This invention solves the above-mentioned conventional problems, makes foundation work easier during construction, and reduces construction costs. A fire lamp that is inexpensive to use and can perform stable firing similar to conventional methods. It was completed in order to provide a batch kiln using the kiln method.

[0005]

[Means to solve the problem]

This invention was developed to solve the above problems, and the upper part of one wall of the furnace body A fire lane method with burners attached to this and the lower part of the opposing wall. In a type batch kiln, the burner speed is 10m/sec or more as the above burner. A high-speed burner is used to form a high-speed swirling flow in the vertical plane inside the furnace, and This device is characterized by an exhaust port with a damper formed in the ceiling of the main body. The present invention will be explained in more detail below by means of illustrated embodiments.

[0006]

【Example】

In FIG. 1, 1 is the furnace body of the batch kiln, and inside the furnace body 1 there is a The structure is such that the trolley 3 carrying the product 2 can move in and out along the rail 4. Ru.

[0007] A burner 6 is installed horizontally at the top of one wall 5 of the furnace body 1. Further, on the wall surface 7 of the furnace body 1 facing this wall surface 5, a similar burner 8 is provided at the bottom thereof. is installed horizontally. In this invention, these burner 6, burner 8, compared to those used in conventional fire lane batch kilns. Also, the burner speed is high, 10-200m/sec, more preferably 40-100m/sec. i am using a ner. For this reason, the injection from these burners 6 and 8 is The combustion gas generated in the furnace forms a high-speed swirling flow that swirls in the vertical plane.

[0008] Further, in the present invention, an exhaust port 9 is formed in the ceiling of the furnace body 1. Example In this case, exhaust can be exhausted from two places on the left and right, but such exhaust port 9 is It is installed above the product to be fired 2 so that the combustion gas in the furnace passes between the products to be fired 2. It is preferable that the gas be discharged from the exhaust port 9. 10 adjusts the displacement It is a damper for It is supported and can be raised and lowered.

[0009]

[Effect]

The fire lane type batch kiln of the present invention configured as described above has three carts. The product 2 to be fired is placed on the top of the wall 5 of the furnace body 1. The burners 6 and 8 attached to the lower part of the wall surface 7 facing each other are used to burn the burners. The combustion gas is ejected at a high velocity of 10 to 200 m/sec, and the high Firing is performed while forming a rapid swirling flow. and installed on the ceiling of the furnace body 1. A controlled amount of air is exhausted from an exhaust port 9 with a damper 10.

0010 Exhausting air from the ceiling of the furnace body 1 in this way is similar to the conventional fire lane method. In batch kilns, it was disliked because it disturbed the flow velocity distribution in the furnace. However, in this invention, burners 6 and 8 have a high burner speed of 10 m/sec or more. Because a fast burner is used, the kinetic energy of the swirling flow completely overcomes the influence of gravity. Therefore, the flow velocity distribution is not disturbed even if exhaust is exhausted from the ceiling of the furnace body 1. Therefore, this invention The kiln is capable of firing in the same way as a conventional batch kiln, which exhausts air from under the floor.

[0011] Moreover, since the batch kiln of the present invention has the exhaust port 9 in the ceiling of the furnace body 1, Unlike in the past, there is no need for foundation work such as digging a pit under the floor during construction, and the construction period is reduced. In addition to shortening the time, construction costs can also be significantly reduced.

0012

[Effect of the idea]

As explained above, this invention uses a high-speed burner with a burner speed of 10 m/sec or more. A damper is installed on the ceiling of the furnace body to create a high-speed swirling flow in the vertical plane inside the furnace. By forming an exhaust port with a Unlike conventional batch kilns, foundation work during construction is easy, construction costs are low, and construction costs are low. Moreover, it is possible to perform stable firing similar to the conventional method. Therefore, this invention is a fire lane batch kiln that solves the problems of the conventional method. Therefore, its practical value is extremely large.
