现有技术中的尿素溶液生产设备主要分为三种，一种是大型化工设备，一般用于专业的大型尿素溶液生产厂家，一种为集成度不高的小型设备，这种设备一般由三个以上部件组成，往往需要在安装现场将这些部件拼接，这给设备的安装调试带来了极大的困难。还有一种则是高度集成化的尿素溶液生产设备，设备中集成了净水、空气能加热、搅拌、溶液存储、上料等多个模块，这种设备虽然集成度很高，但这种设备体积较大，不便于运输，设备内部管路布置复杂不便于批量生产。
结合图1至图8所示，根据本发明的实施例，提供了一种尿素机。
具体地，该尿素机包括柜体10、搅拌罐20、过滤部30、水箱部40和加热部50。搅拌罐20设置于柜体10内。过滤部30设置于柜体10内。水箱部40的进口与过滤部30的出口相连通。加热部50设置于柜体10内，加热部50与水箱部40的出口相连通，加热部50的出口与搅拌罐20相连通。
在本实施例中，采用单独的加热部50对水箱部40内的水进行加热，然后将经加热部50加热过的水输送至搅拌罐20中进行制作尿素，这样设置使得加热部50能够及时的对水箱部40内的水进行加热，有效地提高了该尿素机的效率，满足了用户需求。
其中，加热部50位于搅拌罐20、过滤部30以及水箱部40中至少一个的一侧。这样设置能够有效地降低尿素机的壳体的加工难度，使得尿素机的布局更加合理简单。当然，如图5所示，加热部50均位于搅拌罐20、过滤部30以及水箱部40的一侧。
其中，过滤部30包括过滤器。过滤器设置于柜体10的底部，过滤器的进水口与外界水源相连通，过滤器的出水口与水箱部40相连通。这样设置能够有效地将来自外界水源中的杂质过滤掉，有效地提高了尿素溶液的质量。
进一步地，过滤器包括滤芯过滤器31。滤芯过滤器31的进水口与外界水源相连通，滤芯过滤器31的出水口与水箱部40相连通。这样设置能够有效地过滤掉水源中的小颗粒细沙和其他杂质。
为了进一步地提高过滤器的过滤性能，过滤器还包括活性炭过滤器32的进水口与滤芯过滤器31的出水口相连通，活性炭过滤器32的出水口与水箱部40相连通。这样设置能够有效地去处来自滤芯过滤器31中水中的小分子有机物以及重金属。
为了保证整个水循环中具有足够的水压力，过滤部30还包括第一水泵33。第一水泵33设置于搅拌罐20与水箱部40之间的管路上。
过滤部30包括膜层过滤部34。膜层过滤部34设置于搅拌罐20与水箱部40之间的管路上并位于第一水泵33的上方。这样设置能够进一步地起到对外界水源的过滤作用，有效提高了水的质量，进而提高了尿素溶液的质量，增加了尿素机的可靠性。
水箱部40包括中间水箱41。中间水箱41设置于搅拌罐20的上方，中间水箱41的进水口与过滤部30的出水口相连通，中间水箱41的出水口与加热部50相连通。这样设置能够起到将经过滤好的水储存在中间水箱的作用，使得当需要进行大批量生产尿素溶液时有足够的水源进行备用。
水箱部40还包括纯水水箱42。纯水水箱42设置于过滤部30的上方并与中间水箱41并排设置，纯水水箱42的进水口与中间水箱41的出水口相连通，纯水水箱42出水口与加热部50相连通。这样设置使得纯水水箱42制备纯水时可以通过利用中间水箱41中的水进行制备纯水，然后输入加热部50进行加热。有效地提高了尿素机的制作尿素的速率。
水箱部40还包括储液箱43。储液箱43设置于柜体10的底部上，第一水泵33位于储液箱43的一侧，储液箱43的进液口与搅拌罐20的出液口相连通，储液箱43的出液口与用户端相连通。将储液箱43与第一水泵33设置在柜体10的底部上，这样设置避免了将重量较重的第一水泵33设置在储液箱43上而造成尿素机柜体重心偏高不稳定的情况。在底部设置储液箱43能够将在搅拌罐中制备好的尿素溶液储存起来以备用。
过滤部30包括第二水泵35。第二水泵35设置于柜体10的底部上，第二水泵35位于连接中间水箱41与搅拌罐20之间的管路上。这样设置能够有效地保证管路之间具有足够的水压进行水流输送。
如图1至图4所示，尿素机包括吸料装置21。吸料装置21具有吸料口和出料口，出料口与搅拌罐20的搅拌腔相连通，吸料口用于吸附尿素以将尿素输送至搅拌腔内。采用吸料装置对尿素颗粒进行送料，有效地增加了尿素颗粒的送料的稳定性和可靠性。
其中，吸料装置21包括壳体。壳体的第一端设置有进料口211，壳体的第二端设置有出料口，壳体上还具有排气口212，排气口212用于排出壳体内的空气，进料口211形成吸料口。这样设置有效地增加了尿素颗粒的送料的稳定性和可靠性。
吸料装置21还包括隔板213。隔板213设置于壳体内，隔板213与壳体侧壁之间分别形成排气通道和排气通道，排气口212与排气通道相连通，隔板213的底部与壳体的侧壁之间形成连通进气通道和排气通道的过流口。这样设置能够使得尿素颗粒经过管道输送进入客体内的进气通道然后通过出料口送入搅拌罐中进行尿素制备，这样设置避免了排气口中的排气吸附力对进入客体内的尿素颗粒产生影响进而将尿素颗粒通过排气口排掉，造成尿素颗粒的浪费以及增加了尿素生产成本。有效地提高了该尿素机的经济效益。
进一步地，隔板213包括第一板段2131和第二板段2132。第一板段2131沿竖直方向设置，第一板段2131的第一端与壳体相连接，进料口211与排气口212位于第一板段2131相对的两侧。第二板段2132与第一板段2131的第二端相连接并具有夹角，第二板段2132远离排气口212设置。这样设置能够有效地防止尿素颗粒堵塞在进料口处，同时防止了尿素颗粒被排出造成资源浪费的问题。
优选地，第二板段2132于第一板段2131的第二端相连接并具有夹角，夹角呈直角。这样设置能够有效地避免尿素颗粒被排出造成浪费的问题。同时，将夹角设置成直角，能够有效地起到缓冲尿素颗粒落入搅拌罐的速度，防止大量颗粒同时堆积在吸料装置送料口而造成堵塞的问题。
如图3和图4所示，为了使得尿素颗粒能够顺利的进入搅拌罐中，吸料装置21包括抽吸部22。抽吸部22具有吸口和出口，出口与进料口211相连通，吸口形成吸料口。吸口位于装有尿素颗粒的容器内，出口与进料口相连通，这样开启抽吸部22电机工作时，就能够顺利的将尿素颗粒输送至搅拌罐中。
为了防止有一部分尿素颗粒随着排气通道排出，将该吸料装置21设置成多个，各吸料装置21的出料口均与搅拌罐内腔相连通，相邻两个吸料装置21中的一个吸料装置21的进料口211与另一个吸料装置21的排气口212相连通。这样设置使得当一部分的尿素颗粒通过前边一个吸料装置的排气通道排出时，该部分的尿素颗粒再次进入下一个吸料装置中，并通过吸料装置中的进气管道输送至出料口处并进入搅拌罐中，起到二次排气的作用，依次类推。这样设置能够有效地将从输送管中的尿素颗粒全部都送入至搅拌罐中进行尿素溶液的制备，使得尿素颗粒的利用率达到百分之百和零浪费。
其中，加热部50包括加热水箱，加热水箱用于储存和加热来自水箱部40的水。这样设置使得该加热水箱能够起到储存一定热量温度的水，再进行尿素溶液制备时，将水箱部40的水输送至加热水箱中进行加热，由于加热水箱中原先就储存有相当高的温度的水，使得来自 水箱部40的水与原先的水混合后经过短时间的加热就能使得加热水箱中的水达到所需水温，继而将其输送至搅拌罐中进行尿素溶液的制备，能够有效地缩短了制备尿素溶液所需水的加热时间，提高了该尿素溶液的适用性和可靠性。
该尿素机采用分体结构，将尿素机设备分成主机和副机两部分，主机集成超纯水过滤、超纯水存储、尿素颗粒上料、尿素溶液搅拌、尿素溶液存储，副机为空气能热水器，主要负责超纯水加热。主机采用三层式布置结构，底层布置水泵、成品溶液存储箱、搅拌箱等笨重、需经常维修调节的物料，中层布置RO反渗透膜、水管、电磁阀、重量较轻的水泵等需经常调节维护的物料，顶层布置中间水箱、超纯水水箱、EDI等重量轻的物料，使主机重心尽量降低，便于设备运输、结构稳定。将需经常维修、更换、维护等物料布置在易于维修、更换、维护的位置。采用空气能热水器进行加热，利用热泵原理，从周围环境中吸收热量，通过压缩机将热量输送至冷凝器，释放给水箱的水，把水加热。
吸料装置包括打料部23。打料部23可转动地设置于壳体内以使附着在壳体上的尿素脱落。这样设置能够有效地避免尿素颗粒附着在壳体内壁上从而影响了尿素颗粒的进料速度，这样设置能够保证吸料装置送料速度的稳定性和可靠性。
其中，打料部23包括连接杆231和擀料板232。连接杆231可转动地设置于进料口211处，连接杆231的第一端朝向壳体内延伸，连接杆231的第二端延伸至壳体外。擀料板232与连接杆231的第一端相连接，擀料板232沿壳体侧壁延伸，连接杆231带动擀料板232沿壳体的周向转动。擀料板232在转动的过程中能够将附着在壳体侧壁上的尿素颗粒给弄下来，避免尿素颗粒在壳体内壁上堆积继而影响尿素颗粒进料的稳定性。优选地，将擀料板232的末端设置成与壳体侧壁之间具有间隙。
为了方便作业人员将附着在内壁上的尿素颗粒给弄下来，在连接杆231的第二端上设置了T字形手柄233。通过手握手柄233并转动手柄233就能够实现打料的作用。
进一步地，打料部23包括挡料板234。挡料板234设置于壳体内并位于擀料板232的下方。设置挡料板能够起到降低尿素颗粒进入搅拌罐速度的作用，起到缓冲作用，防止进入的尿素颗粒的量过大和过急。同时，挡料板234也起到防止已经位于挡料板234下方的尿素颗粒被反吸至上方的壳体内而被排出至壳体外造成尿素颗粒浪费的情况。
如图2所示，为了能够对壳体内部进行及时的清理，在壳体上还开设了进水口214。通过从进水口214输送水至壳体内就能实现对壳体内部进行清洗，避免了尿素颗粒长时间地附着在壳体内壁上而腐蚀了壳体，影响壳体的使用寿命。
再请参照图1所示，吸料装置包括进料管段60。进料管段60的一端与壳体内腔相连通，进料管段60的侧壁上设置有进料口211，进料管段60的另一端为自由端且封闭，部分的连接杆231位于进料管段60内且同轴设置。这样设置能够有效地将连接杆231设置在壳体上并实现转动。
具体地，该尿素机包括柜体10和控温部70。控温部70设置于柜体10内，控温部70用于控制柜体10内的温度处于预设温度范围内。

其中，尿素机包括搅拌罐20和水箱部40，搅拌罐20和水箱部40设置于柜体10内，控温部70用于控制水箱部40内的尿素溶液的温度处于预设温度范围内。这样设置能够有效地将设置在柜体10内水箱的温度始终保持恒定在一定温度范围值内，有效地提高了该尿素机使用性和制备尿素溶液的可靠性。
进一步地，水箱部40包括储液箱43。储液箱43设置于柜体10的底部上，储液箱43的进液口与搅拌罐20的出液口相连通，储液箱43的出液口与用户端相连通，控温部70用于控制储液箱43内的温度以使储液箱43内的尿素溶液的温度处于预设温度范围内。这样设置能够有效地控制储液箱43中尿素溶液的储存温度。优选地，记预设温度为t，其中，5℃≤t≤35℃。即柜体10的内部温度控制在该范围内可以有效地避免储存在储液箱43内的尿素溶液不会因温度过高或过低而影响尿素溶液的质量。
其中，控温部70包括制冷装置71。制冷装置71设置于柜体10上以降低柜体10内的温度。为了避免柜体内部温度过高，在柜体10上设置了能够起到降低柜体内部温度的制冷装置71。其中，该制冷装置可以是蒸发器，也可以是风扇之类的散热器。

优选地，发泡材料包括异氰酸酯和组合聚醚。采用异氰酸酯和组合聚醚制成的门板结构具有较强的保温效果。
为了进一步地提高门板结构的保温功能，避免柜体内部的空气通过门板结构与外界空气进行热交换，在门板本体内的边沿处设置有海绵和发泡橡胶。当然也可以是海绵和发泡橡胶中的一种。
采用分体式结构，将尿素机设备分成主机和副机两部分，主机集成超纯水过滤、超纯水存储、尿素颗粒上料、尿素溶液搅拌、尿素溶液存储，副机为空气能热水器，主要负责超纯水加热。
主机采用三层式布置结构，底层布置水泵、成品溶液存储箱、搅拌箱等笨重、需经常维修调节的物料，中层布置RO反渗透膜、水管、电磁阀、重量较轻的水泵等需经常调节维护的物料，顶层布置中间水箱、超纯水水箱、EDI等重量轻的物料，使主机重心尽量降低，便于设备运输、结构稳定。
将需经常维修、更换、维护等物料布置在易于维修、更换、维护的位置。
采用空气能热水器进行加热，利用热泵原理，从周围环境中吸收热量，通过压缩机将热量输送至冷凝器，释放给水箱的水，把水加热。
进一步地，将超纯水直接送入空气能热水器加热至35℃以上。采用空气能热水器进行加热，利用热泵原理，从周围环境中吸收热量，通过压缩机将热量输送至冷凝器，释放给水箱的水，把水加热，减少能量交换环节，提高加热效率。空气能热水器的水箱采用发泡保温，避免加热的超纯水热量损失。具体地，整个尿素机的工作流程包括：水源→预处理(去除颗粒杂质)→两级反渗透(初步去除水中离子)→EDI(进一步去除水中的微量离子)→超纯水→空气能热水器(将水加热到35℃以上)→搅拌箱→成品箱。
其中，抽吸部22从装有尿素颗粒的容器(如图3和图4中A所示)中吸取尿素颗粒并将尿素颗粒送至吸料装置21(图3和图4中分别示出了两个吸料装置21)中，并通过吸料装置21的送料口(如图1和图2中B处所示)送至尿素搅拌罐中进行尿素溶液的制取。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。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。
