1、传统的此类结晶罐结晶过程中易结成较大块状且易沾附，造成取料不便，且后续还要进行破碎，较为麻烦；
2、传统的此类结晶罐不便于利用余热和除去有毒气体，结晶过程中产生水蒸气和有毒气体，直接排放会影响周边环境；
3、传统的此类结晶罐缺少回收结晶过程中产生的液体进行阶段降温，一般全部采用外部水资源，较为浪费不节能。
实用新型内容
本实用新型的目的在于提供一种节能型丙烯酰胺生产用结晶罐，以解决上述背景技术中提出的结晶过程中易结成较大块状且易沾附、不便于利用余热和除去有毒气体和缺少回收结晶过程中产生的液体进行阶段降温的问题。
为实现上述目的，本实用新型提供如下技术方案：一种节能型丙烯酰胺生产用结晶罐，包括罐体、保温通气层和反应罐，所述罐体底端的四周均竖 直安装有支撑柱，且罐体的内部设置有保温通气层，所述保温通气层一侧的罐体内部设置有反应罐，且罐体顶端一端的中间位置处竖直安装有进料斗，所述罐体底端中央位置处竖直安装有贯穿罐体并延伸至反应罐内部的出料管，且罐体一侧的上端安装有净化罐，所述净化罐下方的罐体侧壁安装有水箱，且净化罐底端中央位置处竖直安装有贯穿水箱顶端的导流管。
优选的，所述罐体顶端的中央处竖直安装有电机，且电机的输出端贯穿罐体顶端竖直安装有转杆，所述转杆外壁的四周均匀水平安装有搅拌棒，且转杆的底端安装有刮板。
优选的，所述搅拌棒之间的中央位置处通过轴承竖直安装有转轴，且转轴的两侧均安装有敲击板，所述敲击板同一高度的罐体两侧均水平安装有挡板，且罐体内壁的中央位置处均安装有破碎齿。
优选的，所述罐体顶端远离进料斗的一端竖直安装有气筒，且气筒内部顶端的中央位置处竖直安装有弹簧，所述弹簧的底端安装有顶块，且顶块上方气筒一侧安装有贯穿罐体顶端并延伸至保温通气层内部的进气管。
优选的，所述净化罐的顶端均匀开设有通气口，且净化罐靠近罐体一侧的中央位置处水平安装有贯穿保温通气层的通气管，所述净化罐内部中间位置处的下端安装有喷雾器，且净化罐内部两侧的上端水平安装有折流板，所述折流板上方的净化罐两侧水平安装有吸附层。
优选的，所述水箱内部底端靠近罐体的一端安装有水泵，且水泵输出端安装有贯穿水箱和罐体并延伸至保温通气层内部的进水管，所述进水管的一端连接在缠绕在反应罐外壁的冷凝管进水口，且冷凝管出水口水平连接有贯穿罐体侧壁并延伸至净化罐内部的出水管。
与现有技术相比，本实用新型的有益效果是：
(1)通过安装有进料斗、反应罐、电机、转杆、搅拌棒、刮板、敲击板、挡板和破碎齿，通过进料斗将原料加入反应罐内部，进行加热，启动电机工 作带动转杆转动从而带动搅拌棒和刮板转动，通过搅拌棒搅拌使之充分反应，通过刮板防止结晶在反应罐内部底端粘连，当敲击板撞击到挡板时，敲击板通过转轴转动进行局部搅拌并将大块结晶打散，同时由于搅拌将结晶搅动撞击在破碎齿表面进行破碎，最终加快了反应且避免了结晶粘连和形成较大块状；
(2)同时结晶罐通过安装顶块、弹簧、进气管、保温通气层、喷雾器、净化罐、通气管、吸附层和通气口，在反应的过程中产生的水汽和有毒气体向上顶动顶块使弹簧发生弹性形变而缩短从而使水汽和有毒气体通过进气管排至保温通气层内部，从而达到保温的效果，启动喷雾器将内部的消毒液变成雾状弥漫在净化罐内部，打开通气管处的阀门使水汽和有毒气体排至净化罐内部，经过雾状消毒液消毒和吸附层的吸附后在通气口处排出，从而完成余热利用和消毒；
(3)同时结晶罐通过安装有通气管、净化罐、导流管、水箱、水泵、进水管、冷凝管和出水管，水汽通过通气管排入净化罐内部时由于流通截面增加，流速降低，形成喷洒状，能量损耗，液体在重力作用下自动沉降，气体向上斜抛入折流板底部，从而实现水汽分离，液体经过导流管排至水箱内部回收，启动水泵将水箱内部的清水通过进水管定时排至冷凝管内部进行梯度冷凝降温后在通过出水管和导流管排至水箱内部，从而加快结晶析出，达到节约能源的目的。

水箱10内部底端靠近罐体1的一端安装有水泵12，该水泵12的型号可 为ISGD单级水泵，且水泵12输出端安装有贯穿水箱10和罐体1并延伸至保温通气层14内部的进水管11，进水管11的一端连接在缠绕在反应罐15外壁的冷凝管13进水口，且冷凝管13出水口水平连接有贯穿罐体1侧壁并延伸至净化罐5内部的出水管8；
启动水泵12将水箱10内部的清水通过进水管11定时排至冷凝管13内部进行梯度冷凝降温后在通过出水管8和导流管9排至水箱10内部，从而加快结晶析出，达到节约能源的目的。
工作原理：接通外壁电源，通过进料斗26将原料加入反应罐15内部，进行加热，启动电机25工作带动转杆23转动从而带动搅拌棒19和刮板17转动，通过搅拌棒19搅拌使之充分反应，通过刮板17防止结晶在反应罐15内部底端粘连，当敲击板20撞击到挡板21时，敲击板20通过转轴22转动进行局部搅拌并将大块结晶打散，同时由于搅拌将结晶搅动撞击在破碎齿24表面进行破碎，最终加快了反应且避免了结晶粘连和形成较大块状；
在反应的过程中产生的水汽和有毒气体向上顶动顶块28使弹簧30发生弹性形变而缩短从而使水汽和有毒气体通过进气管29排至保温通气层14内部，从而达到保温的效果，启动喷雾器6将内部的消毒液变成雾状弥漫在净化罐5内部，打开通气管7处的阀门使水汽和有毒气体排至净化罐5内部，经过雾状消毒液消毒和吸附层3的吸附后在通气口2处排出，从而完成余热利用和消毒；
水汽通过通气管7排入净化罐5内部时由于流通截面增加，流速降低，形成喷洒状，能量损耗，液体在重力作用下自动沉降，气体向上斜抛入折流板4底部，从而实现水汽分离，液体经过导流管9排至水箱10内部回收，启动水泵12将水箱10内部的清水通过进水管11定时排至冷凝管13内部进行梯度冷凝降温后在通过出水管8和导流管9排至水箱10内部，从而加快结晶析出，达到节约能源的目的。
