一种硅铝蓄热砖
技术领域
本发明涉及蓄热材料领域,具体来说涉及一种硅铝蓄热砖。
背景技术
随着经济的发展,能源紧张和环境问题已经成为全球共同关注的焦点问题,节能与环保也越来越引起人们的重施。蓄热技术是解决能源危机、实现节能的重要手段之一。通过蓄热技术可以用于工业用热和采暖用热的蓄热储能的设备中,用来提高热能利用率,且减少污染物的排放;通过在蓄热储能的设备里安装蓄热材料可以起到吸热快、蓄热时间长、放热慢的作用,从而达到节约能源的目的;通过在用电谷底时期用蓄热材料进行蓄能,在用电高峰时期放热供暖,可以减缓电网运行的压力,并且在谷电时的电费价格便宜,使用此种方式的用户可以节省费用达到相同的使用要求。
而现有的供暖设备储热一般采用蓄热砖,普通的蓄热砖存在易变形,使用寿命短,保温性能差,热利用效率低,存在热衰减,配比和工艺整体成本高的缺点。
发明内容
针对相关技术中的问题,本发明提出一种硅铝蓄热砖,比热容高,蓄热性能好;耐高温,不易变形,无热衰减。
为了实现上述技术目的,本发明的技术方案是这样的:
一种硅铝蓄热砖,由以下重量百分比的原料制成:铝矾土97-99%及水1-3%,所述铝矾土的具体成分为:二氧化硅55-56%,三氧化二铝34-35%,三氧化二铁6-7%,二氧化钛1.5-2%,氧化钙0.9-1.2%,氧化镁0.4-0.5%,氧化钾0.95%,氧化钠0.034%。
进一步的,由以下重量百分比的原料制成:铝矾土99%及水1%,所述铝矾土的具体成分为:二氧化硅55%,三氧化二铝34%,三氧化二铁6.03%,二氧化钛1.536%,氧化钙1.05%,氧化镁0.4%,氧化钾0.95%,氧化钠0.034%。
一种硅铝蓄热砖的制造方法,包括以下步骤:
S1:破碎:称取重量百分比为97-99%的铝矾土,经颚式破碎机、轮式破碎机加工成为粒度为0~3mm的粘土粉料,所述铝矾土的具体成分为:二氧化硅55-56%,三氧化二铝34-35%,三氧化二铁6-7%,二氧化钛1.5-2%,氧化钙0.9-1.2%,氧化镁0.4-0.5%,氧化钾0.95%,氧化钠0.034%;
S2:混合:在上述的粘土粉料中加入重量百分比为1-3%的水,经搅拌机混匀后制砖备用;
S3:成型:将混好的料在110T~300T的压力下压制成型为砖坯;
S4:干燥:将制成的砖坯装入烧制窑的烘干区域里,烘24~48小时;
S5:烧成:将烘干的砖坯装入烧制窑里,缓慢加温至1200℃,冷却后,拣选包装。
进一步的,步骤S5中缓慢加温24~48小时。
本发明的有益效果:相较于普通的蓄热砖,硅铝蓄热砖承受恒定压负荷产生变形的温度更高,更不易发生变形;硅铝蓄热砖的比热容比普通蓄热砖要高,并且比热容的数据涵盖了从低温储热到高温储热时不同阶段,储热能力更强,并且材料易得,此配比和工艺的制作成本更低,成本仅为普通蓄热砖40%左右。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本发明保护的范围。
实施例1:S1:称取含二氧化硅55kg、三氧化二铝34kg、三氧化二铁6kg、二氧化钛1.5kg、氧化钙0.9kg、氧化镁0.4kg、氧化钾0.95kg、氧化钠0.034kg的铝矾土,经颚式破碎机、轮式破碎机加工成为粒度为0~3mm的粘土粉料;S2:在粘土粉料中加入重量百分比为1kg的水,经搅拌机混匀后制砖备用;S3:将混好的料在110T~300T的压力下压制成型为砖坯;S4:将制成的砖坯装入烧制窑的烘干区域里,烘24~48小时;S5:将烘干的砖坯装入烧制窑里,缓慢加温至1200℃,加温24~48小时,冷却后,拣选包装。
实施例2:S1:称取含二氧化硅56kg、三氧化二铝35kg、三氧化二铁7kg、二氧化钛2kg、氧化钙1.2kg、氧化镁0.5kg、氧化钾0.95kg、氧化钠0.034kg的铝矾土,经颚式破碎机、轮式破碎机加工成为粒度为0~3mm的粘土粉料;S2:在粘土粉料中加入重量百分比为3kg的水,经搅拌机混匀后制砖备用;S3:将混好的料在110T~300T的压力下压制成型为砖坯;S4:将制成的砖坯装入烧制窑的烘干区域里,烘24~48小时;S5:将烘干的砖坯装入烧制窑里,缓慢加温至1200℃,加温24~48小时,冷却后,拣选包装。
实施例3:S1:称取含二氧化硅55.5kg、三氧化二铝34.41kg、三氧化二铁6.82kg、二氧化钛1.59kg、氧化钙1.11kg、氧化镁0.46kg、氧化钾0.95kg、氧化钠0.034kg的铝矾土,经颚式破碎机、轮式破碎机加工成为粒度为0~3mm的粘土粉料;S2:在粘土粉料中加入重量百分比为2kg的水,经搅拌机混匀后制砖备用;S3:将混好的料在110T~300T的压力下压制成型为砖坯;S4:将制成的砖坯装入烧制窑的烘干区域里,烘24~48小时;S5:将烘干的砖坯装入烧制窑里,缓慢加温至1200℃,加温24~48小时,冷却后,拣选包装。
实施例1-3,在硅铝蓄热砖的制作过程,有时会需要一种粘合剂,取决于原料的质量,若成品表面较粗糙就添加粘合剂(将S2工艺后的材料人工磨成面状,粘合剂添加量为10%),将粘合剂混在S3中进行之后的工艺。
为了直观的突显本申请硅铝蓄热砖的优越性,现将其与普通蓄热砖的耐热性能、储热性能进行对比:
从上表可以看出,使用普通蓄热砖0.2MPa荷重软化温度数据最好的是1108℃,本发明硅铝蓄热砖是1339℃,可以说明本发明硅铝蓄热砖承受恒定压负荷产生变形的温度更高,更不易发生变形。本发明硅铝蓄热砖主要用于工业用热和蓄热供暖设备储热用,比热容是储热能力性能的重要指标,从上面可以看出从在100℃、400℃、750℃时本发明硅铝蓄热砖的比热容均比普通蓄热砖要高,并且比热容的数据涵盖了从低温储热到高温储热时不同阶段。
以上仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
