窑炉1内部设有若干输送辊105,便于传输产品,使得产品通过输送辊105在窑炉1内部按照移动的速度移动,保证产品依次进行排烟段、烧成段及冷却段,形成发泡陶瓷。A number of conveying rollers 105 are arranged inside the kiln 1 to facilitate the conveying of products, so that the products can move at a moving speed inside the kiln 1 through the conveying rollers 105 to ensure that the products go through the smoke exhaust section, the firing section and the cooling section in sequence to form foam ceramics.
排烟段101用于排烟;烧成段102用于焙烧产品,使其成型;冷却段103用于冷却产品,由于发泡陶瓷成型前,布料呈粉末状,含水率低,焙烧成型的产品体积较大且厚度大,其需要较长的冷却时间,否则容易出现开裂的现象。The smoke exhaust section 101 is used for exhausting smoke; the firing section 102 is used for roasting the product to shape it; the cooling section 103 is used for cooling the product, because the fabric is in powder form before the foamed ceramic is formed, and the moisture content is low. The volume is large and the thickness is large, it needs a long cooling time, otherwise it is prone to cracking.
冷却段103的长度小于排烟段101与烧成段102的长度之和,本实施例中,排烟段101的长度占窑炉1总长度的5%-7%,具体的,排烟段10111的长度占窑炉11总长度的5.5%、6.0%或6.5%;The length of the cooling section 103 is less than the sum of the lengths of the exhaust section 101 and the firing section 102.

Specifically, the length of the cooling section 103 accounts for 42.5%, 43.0%, 43.5%, 44.0%, or 44.5% of the total length of the kiln 1.
此处需要说明的是,此处,将排烟段10111、烧成段10212及冷却段10313按照上述比例进行设置,在保证能将产品烧成并缓慢冷却的情况下,将后缓冷段1033以及快冷段1034设置为双层,将窑炉1在空间上水平占用空间缩短,将后缓冷段1033与快冷段1034沿竖直方向设置,达到双层同时进行冷却的目的,缩小窑炉1的整体占用空间,提高效率。It should be noted here that the smoke exhaust section 10111, the firing section 10212, and the cooling section 10313 are set according to the above-mentioned proportions. Under the condition that the product can be fired and slowly cooled, the post-slow cooling section 1033 And the rapid cooling section 1034 is set as a double layer, which shortens the horizontal space occupied by the kiln 1. The post slow cooling section 1033 and the rapid cooling section 1034 are arranged in the vertical direction to achieve the purpose of simultaneous cooling of the double layer and reduce the kiln The entire furnace 1 occupies space and improves efficiency.
烧成段102用于将布料焙烧成型,其包括依次设置的预热段1021、中高温段1022以及烧成后段1023,烧成段102中的各个阶段均设置有烧嘴3,预热段1021的烧嘴3数量占烧成段102所有烧嘴3总数的15%-18%,具体为16.0%、17.0%;The firing section 102 is used for firing the cloth into shape, which includes a preheating section 1021, a medium-high temperature section 1022 and a post-firing section 1023 arranged in sequence. Each stage in the firing section 102 is provided with a burner 3, and a preheating section The number of burners 3 in 1021 accounts for 15%-18% of the total number of burners 3 in the firing section 102, specifically 16.0% and 17.0%;

急冷段1031内部的温度高于800℃,为了防止前缓冷段1032以及后缓冷段1033冷却速度过快,使 得急冷后的产品产生应力,导致开裂的现象发生,急冷段1031刚过渡到前缓冷段1032处还设置有补温烧嘴3(图中未示出),用于对产品进行补温,使得产品能够均匀缓慢冷却。The temperature inside the quenching section 1031 is higher than 800℃. In order to prevent the cooling speed of the front slow cooling section 1032 and the rear slow cooling section 1033 from being too fast, causing stress on the quenched product and causing cracking, the quenching section 1031 has just transitioned to the front The slow cooling section 1032 is also provided with a supplementary temperature burner 3 (not shown in the figure) for supplementing the temperature of the product, so that the product can be uniformly and slowly cooled.
前缓冷段1032以及后缓冷段1033内部的温度为500℃-700℃,由于焙烧成型后的产品在500℃-700℃范围内,容易出现开裂的现象,故该段内部进行缓慢冷却,防止产品开裂,保证产品的成型质量。The internal temperature of the front slow cooling section 1032 and the rear slow cooling section 1033 is 500°C-700°C. Since the baked product is within the range of 500°C-700°C, cracking is easy to occur, so the inside of this section is slowly cooled. Prevent product cracking and ensure product molding quality.

The hot air outlet is set in front of the air outlet. The other end of the hot air circulation pipe in the cold section 1032 is connected, so that the hot air drawn by the slow cooling exhaust fan 401 is cyclically supplied back into the hot air circulation pipe, and the hot air circulation pipe exchanges heat with the hot air in the front slow cooling section 1032. The purpose of gradually reducing the temperature in the front slow cooling section 1032 is achieved.

Take the hot air circulation pipe set in the front slow cooling section 1032 as an example. The steel pipe enters the inside of the front slow cooling section 1032 from one side, and then from the front slow cooling section 1032. The other side is extended so that only heat is exchanged inside the roller kiln device, and the air volume does not affect the pressure in the kiln.
