Abstract

The utility model provides a gas fuel and firewood multi-fuel combustion kiln which belongs to kilns. The utility model has two functions in one body, and not only can be used for continuously producing traditional multi-fuel combustion pseudoclassic ceramics in great industries, but also can singly combusts gas fuel for calcining other ceramic products. In the utility model, one side wall or both side walls of a kiln body of a ceramic industrial gas kiln are horizontally provided with a plurality of through holes for putting firewood, and the inner part of a kiln cavity is stood with one or two fire blocking walls. When the utility model is used for calcining, the utility model is first preheated and calcined in low temperature by using gas fuel, when temperature is high, firewood is put in for multi-fuel combustion manually or mechanically, so the utility model can realize simulated firewood kiln atmosphere. The utility model saves firewood and reduces pollution, and the utility model is an ideal, practical, homemade and new kiln used for ceramics industries.

Description

Gaseous fuel, firewood multifuel combustion kiln

The utility model provides a kind of gaseous fuel, firewood multifuel combustion kiln, and also available gas fuel burns separately, belongs to the kiln class.

Chinese traditional Jing Dezhen firewood kiln (being commonly called as " wood kiln ") is owing to the required furnace atmosphere of unique roasting pottery modelled after an antique, and continuity always uses in recent years.But because of wood kiln is fuel used is firewood, and rise to high temperature and need a large amount of firewoods, these firewoods are cut open by the main trunk of trees entirely and are formed, cause the significant wastage and the destruction of the forest reserves, add of the pollution of discharging flue gas to atmosphere, country has to stop wood kiln production, and this just directly has influence on the production of porcelain modelled after an antique.Along with progress of science and technology, pottery burns till tunnel cave, pushed bat kiln, roller kilns and the various electric furnace that is also changed into coal down-draft kiln, fire coal, oil, gas with kiln by former flat flame kiln (firewood kiln).The gaseous fuel kiln is because of having the pollution-free and fuel thermal efficiency advantages of higher to atmosphere, and development in recent years is rapid.But the various kiln after improving all can not satisfy the roasting of traditional pottery modelled after an antique, yet traditional wood kiln structure is to throw bavin in the kiln front, more can not be applicable to big industry, serialization production.Domestic and foreign literature by retrieval finds no combine with the advanced ceramics industrial gas kiln technology of one of traditional wood kiln.

The purpose of this utility model provides a kind of gaseous fuel and mixes with firewood and burn till or the refractory ceramics kiln of single fire gaseous fuel dual-purpose, it is realized with doing certain improvement in gas fired kiln furnace sidewall and the kiln chamber real ceramic industry, thereby satisfy the roasting of traditional porcelain modelled after an antique, economize bavin, pollute and lack, and firewood can be the leftover bits of woodwork.

The purpose of this utility model is achieved in that level is uniform on sidewall of the kiln body [2] of coal gas kiln or two sidewalls opens several for throwing in the through hole [4] that firewoods are used in ceramic industry, and through-hole side is hard upright to be set up one stifledly or two stop up wall with flues [6] to having in kiln chamber [3], and guarantees between firebreak [6] and kiln body [2] madial wall apart greater than 200 millimeters; Firebreak [6] is built by laying bricks or stones up to 100～800 millimeters at the bottom of kiln with refractory material, 60～120 millimeters of thickness.The loading of going into kiln-made product can be kiln car, push pedal or direct code and is placed at the bottom of the kiln.During the roasting of this kiln, earlier with gaseous fuel preheating, the roasting burning of low temperature, when rising to high temperature, hand is thrown or machinery is thrown in firewood, gaseous fuel and firewood multifuel combustion are simulated the atmosphere roasting porcelain modelled after an antique of firewood kiln or are not thrown other ceramic of firewood roasting with acquisition, gaseous fuel can be coal gas, all gases fuel such as natural gas.

As from the foregoing, this kiln has the following advantages: 1, a kiln dual-purpose, can use other ceramic of pure gas fuel baking, and the traditional pottery modelled after an antique of multifuel combustion is produced in industry greatly, serialization again, is that reality technology can't realize; 2, equipment improvement is simple easily, process layout is scientific and reasonable; 3, greatly having reduced the firewood consumption, reduced atmospheric pollution level, helped environmental protection and forest conservation, is a kind of desirable practical industrial kiln of homemade new ceramics.

Fig. 1 is the utility model perspective view.

Further narrate the utility model technology contents below in conjunction with accompanying drawing.

This gaseous fuel, firewood multifuel combustion kiln comprise the real ceramic industry all structure facilities of coal gas kiln, such as: wicket [1], kiln body [2], kiln chamber [3] and gas fuel burning apparatus [5], smoke evacuation system [7], temperature measuring equipment [9] and peep hole [8] etc., its cross sectional shape of through hole [4] of opening at the kiln body sidewall by aforementioned content can be arbitrary geometric figure, but sectional area must not be less than 35 * 100 millimeters; Distance should be greater than 100 millimeters between each through hole [4]; The row's number of set through hole [4] and the quantity in hole are all decided according to the size of kiln body [2] sidewall; Pai through hole can be corresponding consistent or be interspersed up and down.The inside and outside of through hole [4] can be thrown the bavin device to realize automatic control by equipped in addition machinery, obtains desirable practical kiln thus.

Claims

1, a kind of gaseous fuel, firewood multifuel combustion kiln, it comprises the structure facility that ceramic industry coal gas kiln is all, such as: wicket [1], kiln body [2], kiln chamber [3] and gas fuel burning apparatus [5], smoke evacuation system [7], temperature measuring equipment [9] and peep hole [8] or the like is characterized in that: level is uniform on two sidewalls of kiln body [2] or a sidewall opens several for throwing in the through hole [4] that firewoods are used; And through-hole side is hard upright to be set up two stifledly or one stop up wall with flues [6] to having in kiln chamber [3], and guarantees between firebreak [6] and kiln body [2] madial wall apart greater than 200 millimeters; Firebreak [6] is built by laying bricks or stones up to 100～800 millimeters at the bottom of kiln with refractory material, 60～120 millimeters of thickness.

2, gaseous fuel according to claim 1, firewood multifuel combustion kiln is characterized in that: through hole [4] cross sectional shape is arbitrary geometric figure, but sectional area must not be less than 35 * 100 millimeters; Distance should be greater than 100 millimeters between each through hole [4]; The quantity in set through hole [4] row number and hole is all decided on the size that kiln is stopped [2] sidewall; Exhausting hole can be corresponding consistent or be interspersed up and down.
