Abstract

The utility model discloses a section-type tunnel kiln, which comprises a kiln body, wherein the kiln body comprises a preheating zone, a cooling zone and a high-temperature zone. A plurality of gates are arranged in the kiln body, the gates divide the kiln body into a plurality of closed kiln sections, the kiln sections are connected through a pipeline, the heat is transferred through the pipeline, the kiln section at the high-temperature zone can transfer waste heat to the kiln section in the preheating zone through the pipeline, a switching control valve is arranged in the pipeline, the gates are of a lifting type and each gate is connected with a motor through a pulley block. The section-type tunnel kiln has the advantages that since the kiln body is divided into the plurality of kiln sections, the products which are required to be burnt at different temperatures can be simultaneously burnt; since the kiln sections are connected through the pipeline and the heat is transferred through the pipeline, the waste heat can be fully utilized, the products not only can be burnt by using open flames, but also can be burnt by using reducing flames, the quality of the burnt products is improved and the specific antiquing demands of certain ceramic products are met especially by using the reducing flames for ceramics.

Description

A kind of sectional type tunnel cave
Technical field
The utility model relates to continuous firing furnace field, is specifically related to a kind of sectional type tunnel cave.
Background technology
Tunnel cave (or pushed bat kiln) is generally a long straight-through tunnel, and fixing wall and vault are arranged at its both sides and top, on the track that lay bottom, is moving kiln car (pushed bat kiln is push pedal).Combustion apparatus is located at the both sides, middle part of tunnel cave (or pushed bat kiln), formed fixing high temperate zone, the high-temperature flue gas that burning produces is under the effect of tunnel cave (or pushed bat kiln) front end chimney or air-introduced machine, along tunnel to kiln hood direction, flow, preheating enters the goods in kiln step by step simultaneously, and this section formed the preheating zone of tunnel cave (or pushed bat kiln).Kiln tail at tunnel cave (or pushed bat kiln) blasts cold wind, the goods of latter one section in cooling tunnel kiln (or pushed bat kiln), flow through goods and after being heated of the cold wind blasting, then extract out and send into drier as the thermal source of dried, this section just formed the salband of tunnel cave (or pushed bat kiln).Upper placement of chassis (or pushed bat kiln push pedal), pack ceramic into, entrance by preheating zone pushes at leisure continuously, conventional machinery pushes, and be loaded with the kiln car (or pushed bat kiln push pedal) of the product of burning till, just the outlet by salband is pushed out gradually, be applied to steel billet laser heating, or ceramic continuous sintering.
Existing tunnel cave (or pushed bat kiln) is passage, and the tunnel cave of channel-type (or pushed bat kiln) mainly exists following shortcoming:
1, function singleness can not be fired the product that different temperatures and atmosphere require simultaneously;
2, can not make full use of the waste heat of kiln, the utilization rate of heat is low;
3, the available limited energy of firing, the energy selectively narrow.
4, can not fire the product that needs reducing flame to fire.
For the product that need to fire with reducing flame, there is in the market shuttle kiln, shuttle kiln can be fired the product that needs reducing flame to fire, improved working condition, but owing to intermittently burning till, accumulation of heat loss and the radiation loss of kiln are large, flue-gas temperature is high, heat consumption is higher, and the production cycle is long, can not produce continuously.
Utility model content
In order to solve the problems of the technologies described above, the utility model proposes a kind of sectional type tunnel cave, this tunnel cave can be fired the product of different temperatures simultaneously, the utilization rate of heat is high, both can use flaming to fire, and also can use reducing flame to fire simultaneously, with short production cycle, can produce continuously.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of sectional type tunnel cave, comprise kiln body, described kiln body comprises preheating zone, salband and high temperate zone, the inside of described kiln body is provided with a plurality of gates that can folding, described gate can be separated into kiln body a plurality of airtight kiln sections, between kiln section and kiln section, can be connected by pipeline, by pipeline transferring heat.
In described preheating zone, salband and high temperate zone, be provided with gate, the kiln section in described high temperate zone can pass to the kiln section in preheating zone by waste heat by pipeline, in described pipeline, is provided with switching control pilot.
Described gate is lift, and each gate is all connected with a motor by assembly pulley.
The Yu Yaoti cooperation place, both sides of described gate is provided with guide wheel or guide groove.
Described gate is made by heat proof material.
A kind of sectional type tunnel cave of the utility model, by gate, kiln car body is separated into a plurality of kiln sections, can fire the product of different temperatures simultaneously, and can be connected by pipeline between kiln section and kiln section, by pipeline transferring heat, can make full use of waste heat, and the tunnel cave of this kiln segmentation both can have been used flaming to fire, also can use reducing flame to fire simultaneously, heat consumption is lower, with short production cycle, can produce continuously, the product quality of firing is high, and especially the reducing flame of pottery is fired and made ceramic antique effective (as black pigment used by women in ancient times to paint their eyebrows look, silver-colored light formula roofing tile, blue bricks etc.).
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
