如图1至图15所示，本发明滚筒干燥机包括壳本体10及门板组件20，所述门板组件20一侧通过第一转轴与壳本体10连接，所述门板组件20绕第一转轴进行翻转实现开合动作，所述门板组件20另一侧设置有锁扣机构201，所述锁扣机构201卡持在壳本体10上，以保证门板组件20与壳本体10的紧密对接；具体地，所述壳本体10一侧开设有卡孔101，所述锁扣机构201一端固定在门板组件20内，所述锁扣机构201另一端凸伸设有卡扣202，所述卡扣202与卡 孔101匹配对接。
所述门板组件20包括框架21及卡持在框架21内的封闭窗22，所述封闭窗22为透明塑料材质构造，用户可透过封闭窗22观察到壳本体10内的被烘干物如衣物的烘干状态；具体地，所述框架21包括后框架211及前框架212，所述封闭窗22固定在后框架211与前框架212之间，所述后框架211靠近前框架212一侧开设有第一环槽2111，所述第一环槽2111内卡持有第一密封圈213，所述封闭窗22紧贴第一密封圈213设置，保证封闭窗22与后框架211相互固定的紧密性，保证本发明的密封性能；所述后框架211靠近壳本体10一侧开设有第二环槽2112，所述第二环槽2112内卡持有第二密封圈214，当门板组件20通过锁扣机构201紧固在壳本体10一侧时，后框架211对第二密封圈214施加压力，使得门板组件20与壳本体10前端部周侧贴合密封，保证本发明的密封性能。
所述壳本体10内固定设置有压力桶30，所述门板组件20、壳本体10及压力桶30共同围设形成一密封腔体301，具体地，所述壳本体10前端部设置有前面板11，所述门板组件20与前面板11一侧贴合设置，所述压力桶30与前面板11另一侧紧固设置，具体地，所述前面板11另一侧开设有第三环槽111，所述第三环槽111内卡持有第三密封圈(图未示)，所述压力桶30前端部凸伸设有对接环部31，所述对接环部31卡持在第三环槽111内并对紧贴第三密封圈设置，从而保证前面板11与压力桶30之间的密封性能；当门板组件20与前面板11贴合后，所述密封腔体301由门板组件20、前面板11及压力桶30共同围设形成。
所述压力桶30内设置有滚筒40，所述滚筒40底端部设置有第二转轴41，所述滚筒40底端部与压力桶30底端部通过第二转轴41连接，具体地，所述压力桶30底端部设置有轴承32，所述第二转轴41卡持在轴承32内，从而使得滚筒40能以第二转轴41为轴芯进行转动，所述压力桶30内设置有支撑轮33，所述支撑轮33抵顶在滚筒40外侧部，从而使得滚筒40能与压力桶30之间保持间距进而方便进行转动，同时，所述支撑轮33能随着滚筒40的转动而进行转动，以降低对滚筒40转动的阻力。
所述滚筒40底端部上开设有多个开孔42，以方便流体从滚筒40内流出，降低流体阻力；所述滚筒40内于滚筒40底端部设置有滤网架43，所述滤网架43上设置有过滤网板431，所述过滤网板431置于开孔42前端部，避免滚筒40内被烘干物上烘干掉落的杂质从开孔42内流出而降低本发明使用效果。
在其中一个实施例中，所述滤网架43上于过滤网板431前端设置有多个凸起部432，以阻挡表面积较大的被烘干物附着在滚筒40底端部而增加流体阻力，降低被烘干物对密封腔体301内压力的干扰，同时能更好地引导流体从滚筒40内流出。
在其中一个实施例中，所述滚筒40内间隔凸设有多个举升筋44，以使得滚筒40在转动时能够带动被烘干物在滚动内进行翻转，提高被烘干物与流体的接触面积，进而提高被烘干物的烘干效率。
所述压力桶30内靠近滚筒40前端部处设置有第四密封圈(图未示)，所述第四密封圈采用毛毡或毛刷材质构造，所述第四密封圈一侧粘接在压力桶30内侧壁，所述第四密封圈另一侧设置有刷毛部，所述刷毛部贴合在滚筒40前端部，当滚筒40绕第二转轴41进行转动时，刷毛部能与滚动前端部滑动连接，以提高对进入滚筒40内流体的阻力。
所述压力桶30下端部设置有驱动机构50，所述驱动机构50用于驱动滚筒40以第二转轴41为轴芯进行转动，所述驱动机构50与压力桶30之间紧密连接，以保证密封腔体301的完整性；所述驱动机构50包括上下两端开口的固定壳体51，所述压力桶30下端部开设有驱动开口34，所述固定壳体51上端部紧贴驱动开口34周侧设置，所述固定壳体51下端部固定设置有盖板52，所述盖板52与固定壳体51下端部周侧的间隙内填充有第五密封圈(图未示)，从而使得盖板52与固定壳体51紧固后对固定壳体51下端部开口进行有效的密封，结合固定壳体51上端部紧贴驱动开口34周侧设置，有效保证了产品的密封性能。
具体地，所述固定壳体51上端部开口构造与压力桶30外侧部构造匹配设置，以方便固定壳体51与压力桶30的稳固贴合，所述固定壳体51上端部开设有凹槽511，所述凹槽511内设置有第六密封圈(图未示)，从而保证固定壳体51上端部与压力桶30的驱动开口34周侧紧密贴合，配合盖板52对固定壳体 51下端部开口的密封作用，有效保证了密封腔体301的密封性能。
所述固定壳体51上设置有驱动电机53，所述驱动电机53一端设置有驱动轮54，所述固定壳体51内设置有弹性架55，所述弹性架55一端卡持有涨紧轮56，所述涨紧轮56分别设置在驱动轮54两侧，所述涨紧轮56与驱动轮54通过驱动皮带57连接，所述驱动皮带57凸伸出固定壳体51并绕设在滚筒40外侧部，当驱动皮带57绕设在滚筒40外侧部后，驱动皮带57通过对涨紧轮56施力进而使得弹性架55产生形变，从而调节涨紧轮56与驱动轮54之间的相对位置，同时利用弹性架55的回复力保证驱动皮带57能紧紧贴合在驱动轮54、涨紧轮56及滚筒40上，当驱动电机53带动驱动轮54转动后，涨紧轮56及滚筒40也同步进行转动，从而使得滚筒40内被烘干物在滚筒40内进行翻转动作。
在其中一个实施例中，所述盖板52上设置有压片58，所述弹性架55底端部置于压片58下方，从而利用压片58将弹性架55固定在盖板52上。
本实施例中，所述涨紧轮56安装高度大于驱动轮54安装高度，所述涨紧轮56中心与驱动轮54中心的连线夹角为锐角，当驱动皮带57绕设在滚筒40外侧部后，驱动皮带57下端部首先接触涨紧轮56，并对涨紧轮56施力使得弹性架55产生形变，弹性架55以驱动轮54为中心向驱动轮54两侧外部进行扩张形变，由于涨紧轮56中心与驱动轮54中心的连线夹角为锐角，使得弹性架55的回复力能让涨紧轮56持续地对驱动皮带57施加稳定压力，保证驱动皮带57能紧紧贴合在滚筒40外侧部及驱动轮54上。
在其中一个实施例中，所述驱动电机53设置在固定壳体51外侧部，所述驱动电机53一端设置有转动轴531，所述驱动轮54固定设置在转动轴531一端，所述转动轴531贯穿固定壳体51设置，从而使得固定在固定壳体51外侧部的驱动电机53能带动固定壳体51内的驱动轮54进行转动，进而使得驱动皮带57带动滚筒40进行转动，在保证密封腔体301密封的前提下让滚筒40进行转动，同时由于驱动电机53在固定壳体51外侧部提供动力，有效避免了驱动电机53的动力部分受滚筒40内蒸汽及液体的侵蚀，进而提高本发明的使用寿命。
所述压力桶30底端部开设有出气口35，所述压力桶30于出气口35处设置有真空泵60，所述真空泵60用于将滚筒40内的流体抽出，所述壳本体10内于 压力桶30底端部外侧设置有冷凝装置70，所述真空泵60与冷凝装置70连接，所述冷凝装置70用于对真空泵60抽出的流体内的蒸汽进行冷凝处理。
所述壳本体10下端部于压力桶30下方设置有回收箱体81，所述回收箱体81为抽屉状构造，所述回收箱体81内设置有收集盒82，所述收集盒82通过抽拉方式完成与回收箱体81的抽离与结合操作，所述冷凝装置70的排液口通过软管与收集盒82连通设置，从而将冷凝装置70收集的液体排放至收集盒82内，所述冷凝装置70一侧设置有格栅71，冷凝装置70的排气口与格栅71连接，从而使得滚筒40内的流体经冷凝装置70处理后的通过格栅71排出。
所述压力桶30外侧部设置有多个流体管道90，所述压力桶30前端部侧壁开设有流体入口36，所述流体管道90一端部凸伸出流体入口36并延伸至压力桶30内，具体地，所述流体入口36匹配设置在滚筒40前端部边缘处，所述流体管道90延伸至压力桶30内的端部位置相比于滚筒40前端部边缘位置更靠近滚筒40前端部截面所在圆心，由于流体管道90一端部凸伸出流体入口36一定距离，从而使得滚筒40转动时不会触碰到流体管道90。
在其中一个实施例中，所述流体管道90一端部弯折设置有弧形部91，所述弧形部91的出口朝向滚筒40底端部所在位置，以方便引导进入密封腔体301内的流体流向滚筒40底端部，具体地，所述弧形部91的出口所在切线方向与滚筒40底端部设置的第二转轴41轴心线所在方向的夹角为0～90°；当滚筒40带动被烘干物在滚筒40内旋转时，具有高度指向的多束流体能够在较低的流量下提高被烘干物的热量补充效率，当密封腔体301内的压力变低时热量通过热对流传递的效率也会变低，在接近绝对真空的条件下热量传递几乎只能依靠热传导和热辐射，由于滚筒40在转动过程中被烘干物并不是长时间与滚筒40内侧筒壁接触，并且无法时刻保持所有被烘干物的表面暴露在热辐射环境中，这两种热量传递方式在滚筒干燥机中的传递效率十分低下，增加流体管道90能够在保持密封腔体301内低压状态时提供少量的流体供给，让补充的流体利用热对流方式对被烘干物进行热量补充，进而完成被烘干物的快速烘干操作。
所述流体管道90设置有第一流道92及与第一流道92连通设置的第二流道93，第一流道92至第二流道93再至弧形部91出口处的横截面积逐渐变小，且 第一流道92至第二流道93再至弧形部91出口的方向逐渐变化，从而能够影响到流体管道90内部对流体的整体阻力，并对流体的速度、流量、压力产生影响；具体地，所述第一流道92及第二流道93对流体的阻力大于出气口35对流体的阻力，从而使得流体流入密封腔体301内的阻力大于流体流出密封腔体301的阻力，在真空泵60的作用下，使得密封腔体301内产生低于环境大气压的负压，利用低压对液体蒸发速率的影响提高被烘干物的烘干效率，其中，负压大小可通过调整真空泵60的工作功率或在流体管道90内安装节流装置来实现。
在其中一个实施例中，所述弧形部91出口截面积之和小于出气口35截面积，从而使得经流体管道90进入到密封腔体301内的流体量小于经密封腔体301从出气口35排出的流体量，由于截面积差的存在，真空泵60在泵出流体的过程中，流体流入密封腔体301的阻力大于流体流出密封腔体301的阻力，以保证密封腔体301内部的负压状态。
所述流体管道90内侧部设置有加热模块94，外部流体进入到流体管道90内部后被加热模块94进行加热，经加热后的流体再由流体管道90一端部的弧形部91出口进入到密封腔体301内，进而对滚筒40内被烘干物进行烘干操作；所述流体管道90内侧还设置有温度传感器95，所述温度传感器95设置在加热模块94与弧形部91出口之间，用于对流体进入到密封腔体301之前的温度进行检测。
在其中一个实施例中，所述弧形部91外侧壁套设有防护套96，所述防护套96为柔性材质构造，所述防护套96用于对流体入口36处形成良好的包裹及密封性能，以减少密封腔体301内的压力损失，同时降低被烘干物翻转过程中剐蹭到弧形部91而受到的物理损伤。
在其中一个实施例中，所述流体管道90另一端部内侧设置有过滤网97，所述过滤网97用于对进入流体管道90内的流体进行过滤，避免外部杂物随着流体进入到流体管道90内。
在其中一个实施例中，所述壳本体10内设置有PCB面板102，所述壳本体10上端部设置有操作面板103，所述壳本体10后端部设置有电源插座104，所述真空泵60、驱动机构50、加热模块94、温度传感器95、操作面板103、电源 插座104等均通过电缆(图未示)与PCB面板102连接，所述PCB面板102上设置有微控制器及驱动电路，以读取或控制所述真空泵60、驱动机构50、加热模块94、温度传感器95、操作面板103的工作状态。
在其中一个实施例中，所述收集盒82内设置有液位传感器83，所述液位传感器83用于对收集盒82内的液面高度进行感应，当收集盒82内收集的液体液面超过预设值时，液位传感器83发送信号给PCB面板102，进而由PCB面板102控制报警装置提醒用户将收集盒82内的液体进行处理。
本发明具体工作时，门板组件20与壳本体10稳固锁紧后，通过电源插座104连接外部电力，用户操控操作面板103上的按键能够对本发明的工作状态进行控制，真空泵60持续工作中能够驱动压力桶30内流体向外流动，由于所有弧形部91出口截面积之和小于出气口35截面积，并且第一流道92及第二流道93对流体的阻力大于出气口35对流体的阻力，使得流体流入压力桶30内的阻力大于流体流出压力桶30的阻力，从而使得密封腔体301内将产生低于环境大气压的负压，根据不同的使用场景，利用PCB面板102上设置的微控制器自动控制调节真空泵60的工作功率、驱动机构50的转速与转向、加热模块94的加热功率等参数，利用低压对液体蒸发速率的影响来提高被烘干物的烘干效率，达到快速烘干潮湿物体的效果。
综上所述，本发明滚筒干燥机通过将门板组件20、前面板11及压力桶30共同围设形成一个密封腔体301，在压力桶30内设置滚筒40，利用在压力桶30外侧部设置一端延伸至压力桶30内的流体管道90，配合在压力桶30底端部开设与真空泵60连接的出气口35，最后利用真空泵60将密封腔体301内的流体排出使得密封腔体301内产生负压状态，从而利用低压对液体蒸发速率的影响来提高被烘干物的烘干效率，达到快速烘干潮湿物体的效果。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明的保护范围应以所附权利要求为准。
