尿素颗粒加投搅拌箱的方式主要有螺旋输送投料和真空吸取投料两种。由于螺旋输送的投料方式具有投放量大、不间断投料、受尿素结块的影响小，因此螺旋输送的投料方式广泛应用于大型化工厂的尿素水溶液的生产中。但螺旋输送投料方式同时具有以下缺点：
需要先将包装的尿素颗粒倒入规定的料斗中，在实际操作中，该过程不仅容易引入各种未知的杂质，从而影响溶液品质，而且导致工人劳动量增加。
随着料斗中尿素颗粒减少，尿素颗粒的投放能力减小，最后附着在料斗壁上的尿素颗粒若不能顺利滑入螺旋杆的活动范围，则无法被顺利的投入混配箱，在小批量生产时，这些未进入溶液混配箱的尿素颗粒将会导致溶液浓度不合格，特别是在小批量生产时，这种影响尤为明显。需要配备专用料斗和螺旋杆输送管道，因而体积大，不利于整机设备的小型化、集成化。
而真空吸取投料方式与螺旋输送投料方式刚好相反，真空吸取投料方式虽不能连续投料，但在小型设备的小批量生产中，其投放量可以满足使用需求。当采用真空吸取方式投料时，工人只需将包装袋打开，并将吸料管插入尿素颗粒中就可以实现投料，并不需要人工将尿素颗粒从包装袋中倒出，这不仅减少了尿素颗粒的污染，而且降低了工人的劳动强度。此外，真空吸取投料方式对管道的布置要求比较小，有利于设备的小型化和集成化。
由于尿素颗粒具有易吸水结晶的特性，传统的真空投料装置容易堵塞分离尿素颗粒与空气的过滤网。
结合图1至图8所示，根据本发明的实施例，提供了一种吸料装置。
具体地，该吸料装置包括壳体。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；隔板213，隔板213设置于壳体内以将进料口211与排气口212隔离，隔板213与壳体侧壁之间分别形成进气通道和排气通道，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。
在本实施例中，通过在进料口211与排气口212之间设置隔板213以将进料口211与排气口212隔开，有效地防止通过进料口211吸入尿素颗粒并将吸料装置中的气体排出时，尿素颗 粒不会从排气口212出排出造成尿素颗粒的浪费，同时采用该种进料方式能够有效避免尿素颗粒堵塞在进料口处影响尿素溶液生产的问题。
其中，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与第一板段2131的第二端之间的夹角呈直角。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，吸口用于吸附尿素以将尿素输送至壳体内。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。
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可活动地设置于壳体内并位于擀料板232的下方。设置挡料板能够使得抽吸部22工作时，抽吸部22向吸料装置内抽真空，此时，挡料板234向上移动以将位于挡料板234上方的出口封闭，在抽吸部22的作用下，尿素颗粒不断的在壳体内部堆积，当抽吸部22停止工作时，挡料板234向下方转动并将出口打开，此时尿素颗粒进入搅拌罐中，即在抽吸部22间歇性工作中，挡料板234重复实现打开和关闭的动作。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。
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。
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。其中，当抽吸部22处于工作状态时，进水口处于封闭状态，只有当需要向壳体内输入水时进水口才能打开。
如图3和图4所示，壳体为多个，相邻两个壳体中的一个壳体的进料口211与另一个壳体的排气口212相连通。各壳体的出料口均与搅拌罐内腔相连通。这样设置使得当一部分的尿素颗粒通过前边一个壳体的排气通道排出时，该部分的尿素颗粒再次进入下一个壳体中，并通过壳体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。
如图5至图8所示，根据本发明的另一方面，提供了一种尿素机。该尿素机包括吸料装置，吸料装置为上述实施例中的吸料装置。具体地，该吸料装置包括壳体。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；隔板213，隔板213设置于壳体内以将进料口211与排气口212隔离，隔板213与壳体侧壁之间分别形成进气通道和排气通道，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。通过在进料口211与排气口212之间设置隔板213以将进料口211与排气口212隔开，有效地防止通过进料口211吸入尿素颗粒并将吸料装置中的气体排出时，尿素颗粒不会从排气口212出排出造成尿素颗粒的浪费，同时采用该种进料方式能够有效避免尿素颗粒堵塞在进料口处影响尿素溶液生产的问题。
其中，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。
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。
