Description

Brickmaking is with external-burning baking apparatus and adobe method for cooking

Technical field

The present invention relates to brick-making technology, the external-burning baking apparatus is used in particularly a kind of tunnel cave brickmaking, and the adobe method for cooking that adopts this device.

Background technology

Traditional machine made brick adopts the mode of internal combustion roasting to fire, and promptly in adobe base process, the combustion value is mixed into blank, then tunnel cave mid point burning system is sent in adobe.Tunnel cave divides on kiln body total length direction, is divided into 60 ℃ of preheating sections usually according to the temperature difference--600 ℃ of 600 ℃, high temperature calcination section (about 900 ℃--1000 ℃) and cooling sections--60 ℃.Tunnel cave advances the base end and establishes wicket, and the adobe that contains the combustion value is lighted back self burning at high temperature calcination section, and burning institute oxygen consumption gas gets into from cooling section naturally.Under the air mobilization, produce thermograde by high temperature calcination section to both sides wicket in the tunnel cave, form preheating section and pre-burning section naturally in a side, then form cooling section in other side.

It is following two not enough easily that above traditional internal combustion roasting mode mainly exists, one of which, the combustion value incomplete combustion in the adobe; The combustion value is utilized insufficient; Each standard-sized adobe only need add the combustion value of 700 kilocalories in theory, but for guaranteeing to fire quality, often adds the combustion value of 1000 kilocalories in the actual production; Promptly there is 30% combustion value not utilize and waste approximately, is unfavorable for energy savings, reduces carbon emission and reduce production costs; Its two, the high temperature calcination section temperature can not accurately be controlled in the kiln, restively fires quality and each batch quality is consistent.

Summary of the invention

Technical problem to be solved by this invention provides a kind of brickmaking and uses the external-burning baking apparatus, can reduce adobe effectively and fire institute power consumption source, and guarantee that effectively adobe fires quality.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the external-burning baking apparatus is used in brickmaking of the present invention; It is characterized in that: it comprises drying kiln and calcining kiln, and kilneye place, calcining kiln two ends is provided with closed advance base end wicket, brick output end wicket respectively; Calcining kiln stage casing longitudinal separation is provided with the spray combustion system, and is bleeding and induction system near advancing the one side setting of base end wicket, forms pre-burning section, high temperature calcination section and cooling section successively advancing base end wicket to brick output end wicket.

Another technical problem to be solved by this invention provides a kind of adobe method for cooking that utilizes above-mentioned brickmaking with the external-burning baking apparatus; This method comprises the steps: 1. to dry adobe; The adobe that will contain 0～50% combustion value is sent in the drying kiln by transport, and its water content is removed in oven dry; 2. pass on adobe, open base end wicket, car oven dry back adobe is transferred to calcining kiln at every turn, close into base end wicket after pushing in the calcining kiln through changeing blanking device; 3. roasting, pre-burning section, high temperature calcination section and cooling section are passed through in the per car adobe successively, and wherein experiencing the high temperature calcination section time is 30～50 minutes, and the high temperature calcination section temperature is 960 ± 50 degree, is mixed spraying into required oxygen of roasting and corresponding combustion value by the spray combustion system; 4. brick output is opened brick output end wicket, pushes out the adobe that a car has burnt till completion at every turn, and transfers to and pile up station.

The invention has the beneficial effects as follows that the mode that adopts external-burning or external combustion to combine with internal combustion is fired adobe, can reduce adobe effectively and fire institute power consumption source, can practice thrift combustion value 20～30%; Can control high temperature calcination section temperature in the kiln exactly, guarantee to fire quality effectively, and each batch quality is consistent; Can adopt multifarious combustion value,, can make full use of the industrial and agricultural production discarded object, help improving the environmental protection situation like coal, straw, sawdust etc.
