[0034] 具体实施方式
[0035] 如图 1和图 2所示， 一种圆环式干燥机， 用于干燥浆状物料， 它包括壳体 20， 设于壳体 20顶部的顶盖 10， 以及设于壳体 20底部的底座 30， 还包括待干燥物料 流入的进料系统 40， 物料涂布组件 50， 物料挤压组件 60， 卸料刮刀 70， 以及至 少两个不同半径的筒体 21。 如图 1至图 4， 图 10， 图 11所示， 筒体 21为圆筒状结构， 筒体 21内部设有热介质 流道 212， 本申请中， 筒体 21为内部设有圆环形空腔的筒体， 圆环形空腔形成热 介质流道 212， 或者在圆环形空腔内布设折流板形成热介质流道 212。 筒体 21固 定设于壳体 20内， 且相邻筒体 21之间形成环形槽 22， 筒体 21和壳体 20同轴线设 置。 进料系统 40横向设于壳体 20内且可围绕壳体 20轴线旋转， 进料系统 40由横 杆 41和进料管 42组成， 或者由横杆 41和进料圆盘组成， 进料管 42的管壁设有出 料口 43或者进料圆盘的底部设有出料口 43， 出料口 43的数量与环形槽 22数量相 等， 当进料系统 40由横杆 41和进料管 42组成时， 横杆 41和进料管 42的数量与环 形槽 22数量相等， 每根进料管 42都设有一出料口 43， 进料系统 40内的待干燥物 料沿着出料口 43流向环形槽 22内。 物料涂布组件 50， 物料挤压组件 60和卸料刮 刀 70活动设于环形槽 22内且可相对筒体 21沿着环形槽 22移动， 卸料刮刀 70的刀 刃分别与筒体 21的内周面和相邻筒体 21的外周面接触。 本申请中， 进料系统 40 横向设于壳体 20内且可围绕壳体 20的轴线旋转， 进料系统 40的自由端连接有上 连接板 27， 卸料刮刀 70顶部与上连接板 27连接， 物料涂布组件 50顶部与上连接 板 27连接， 物料挤压组件 60顶部与上连接板 27连接， 卸料刮刀 70底部连接有下 连接板 28， 物料涂布组件 50底部与下连接板 28连接， 物料挤压组件 60底部与下 连接板 28连接。 上连接板 27为圆环形状， 设有用于出料口 43通过的孔洞 29， 上 连接板 27设有用于与卸料刮刀 70顶部， 物料涂布组件 50顶部和物料挤压组件 60 顶部相连接的孔洞 29; 下连接板 28设有用于干燥好的物料通过并进入底座 30的 孔洞 29， 下连接板 28为圆环形状， 设有用于与卸料刮刀 70底部， 物料涂布组件 5 0底部和物料挤压组件 60底部相连接的孔洞 29。 进料系统 40和上连接板 27可以是 可拆式连接， 可以通过气缸连接， 也可以通过弹性件连接， 如弹簧连接， 如进 料系统 40和上连接板 27通过弹簧连接时， 进料系统 40在突然转动时， 弹簧对上 连接板 27的启动起到缓冲作用， 从而保护了与上连接板 27连接的卸料刮刀 70， 物料涂布组件 50和物料挤压组件 60; 卸料刮刀 70与上连接板 27和下连接板 28连 接， 且卸料刮刀 70的刀刃分别与筒体 21的内周面和相邻筒体 21的外周面接触， 卸料刮刀 70可将筒体 21的内周面和相邻筒体 21的外周面上的干燥的物料刮下。 进料系统 40内的待干燥物料沿着出料口 43流向环形槽 22， 在外力的作用下， 进 料系统 40， 物料涂布组件 50， 物料挤压组件 60和卸料刮刀 70相对筒体 21沿着环 形槽 22移动， 物料涂布组件 50将待干燥物料涂布在筒体 21的内周面和相邻筒体 2 1的外周面， 热介质流道 212内通入热介质， 热介质使得筒体 21的内周面和相邻 筒体 21的外周面的待干燥物料干燥， 同时， 卸料刮刀 70将干燥好的物料刮下， 卸料刮刀 70为 V字形结构， 卸料刮刀 70沿着环形槽 22移动的过程中， 卸料刮刀 70 同时将筒体 21的内周面和相邻筒体 21的外周面上的干燥物料刮下。 由于筒体 21 的内周面和相邻筒体 21的外周面均涂布有待干燥物料， 增加了待干燥物料的面 积， 提高了干燥效率， 同时待干燥物料在干燥过程中， 与本申请中的零部件摩 擦较小， 提高了本申请的使用寿命。
[0037] 具体的， 如图 1所示， 物料挤压组件 60包括外挤压带 61， 内挤压带 62， 外挤压 圆辊 63和内挤压圆辊 64。 外挤压圆辊 63带动外挤压带 61沿着环形槽 22旋转移动 ， 且外挤压带 61与筒体 21的内周面接触， 外挤压带 61将待干燥物料压紧在筒体 2 1的内周面； 内挤压圆辊 64带动内挤压带 62沿着环形槽 22旋转移动， 且内挤压带 62与相邻筒体 21的外周面接触， 内挤压带 62将待干燥物料压紧在相邻筒体 21的 外周面。 外挤压带 61和内挤压带 62均为柔性透气材料制成， 可以为多孔橡胶、 多孔软性塑料、 多孔金属薄板、 金属网、 非金属网、 金属布、 非金属布、 泡沫 塑料、 链板、 竹席、 草席中的一种或任意多种组合。 外挤压带 61， 内挤压带 62 分别与筒体 21的周壁平行， 外挤压带 61和内挤压带 62之间设有隔离圆辊 65， 由 于外挤压带 61和内挤压带 62移动的角速度相同， 外挤压带 61的线速度大于内挤 压带 62的线速度， 为防止外挤压带 61和内挤压带 62在旋转移动过程中相互挤压 摩擦而损坏， 在外挤压带 61和内挤压带 62之间设有隔离圆辊 65， 外挤压带 61和 内挤压带 62形成双履带式结构。 外挤压带 61和内挤压带 62在旋转移动过程中， 外挤压带 61使得待干燥物料贴紧筒体 21的内周面， 防止筒体 21的内周面的待干 燥物料脱落， 内挤压带 62使得待干燥物料贴紧相邻筒体 21的外周面， 防止相邻 筒体 21的外周面的待干燥物料脱落。
[0038] 具体的， 如图 2至图 5所示， 物料涂布组件 50包括一对布料圆辊 51， 以及一对布 料板 52， 一对布料圆辊 51纵向设于环形槽 22内且与壳体 20轴线平行， 其中， 一 布料板 52的一端靠近一布料圆辊 51， 另一端与筒体 21的内周面形成一布料口 54 ， 另一布料板 52的一端靠近另一布料圆辊 51， 另一端与相邻筒体 21的外周面形 成一布料口 54。 布料板 52与筒体 21内周面或与相邻筒体 21外周面间的夹角可以 根据需要调整， 进而调整布料口 54的大小。 当布料圆辊 51沿着环形槽 22旋转移 动时， 布料圆辊 51挤压待干燥物料使得待干燥物料成均匀薄片状， 被挤压的待 干燥物料从布料口 54进入并贴在筒体 21的内周面和相邻筒体 21的外周面。
[0039] 如图 1， 图 2和图 6所示， 各个筒体 21顶部分别设有环形板 23， 环形板 23四周均 匀分布有走齿孔 24， 外挤压圆辊 63的顶部设有第一齿轮 25， 内挤压圆辊 64的顶 部设有第二齿轮 26， 第一齿轮 25沿着环形板 23的走齿孔 24转动， 第二齿轮 26沿 着环形板 23的走齿孔 24转动。 外挤压圆辊 63和内挤压圆辊 64的顶部还设置有上 滚轮组 66， 外挤压圆辊 63和内挤压圆辊 64的顶部通过上滚轮组 66连接， 外挤压 圆辊 63和内挤压圆辊 64的底部设置有下滚轮组 67， 外挤压圆辊 63和内挤压圆辊 6 4的底部通过下滚轮组 67连接。

[0041] 如图 1所示， 壳体 20的底部设有热介质进管 210和热介质出管 211， 热介质进管 2 10与筒体 21的热介质流道 212的进口连接， 热介质从热介质进管 210进入筒体 21 的热介质流道 212， 流经热介质流道 212内的热介质将筒体 21的内周面和相邻筒 体 21的外周面的待干燥物料干燥。 热介质出管 211与筒体 21的热介质流道 212的 出口连接。
[0042] 如图 1所示， 顶盖 10设有气体排出口 11和物料入口 12， 物料入口 12与进料系统 4 0的进料口连接。 待干燥物料干燥后产生水汽， 水汽从气体排出口 11排出。
[0043] 如图 1所示， 底座 30内设有环形的耙杆 31， 耙杆 31的轴心与进料系统 40的轴心 通过设有的转轴 32固定连接。 底座 30内还设有电机 33， 电机 33带动转轴 32转动 [0044] 如图 1所示， 本申请中， 耙杆 31通过抱轴器 35与转轴 32相连接， 在耙杆 31上装 有若干水平设置的耙叶 34， 耙叶 34与耙杆 31为可拆卸式连接。 耙杆 31和耙叶 34 位于底座 30内， 且耙叶 34的底端与底座 30的底面相接触， 以移动干燥好的物料 ， 使干燥物料移动到排料口 36。
