具体实施方式DETAILED DESCRIPTION
结合参阅图1-图4，本实用新型提供了污泥脱水装置，包括外筒体1，外筒体1内通过轴承2转动连接有离心筒3，本申请中轴承2设置有两组，分别分布在离心筒3外表面的顶底部位置，这样在离心筒3转动时可提高转动平稳度，外筒体1上设置有用于驱动离心筒3离心转动的旋转驱动单元4，离心筒3内设置有污泥翻涌结构5，污泥翻涌结构5包括固定连接在离心筒3内底部的导料筒51、开设在导料筒51上的进泥槽52和设置在导料筒51内的螺旋叶片53，当导料筒51内进入污泥后，螺旋叶片53的转动可使得导料筒51内的污泥连续向上运输，直至运输至导料筒51的端部可继续进入离心筒3内，这样位于离心筒3内的污泥可实现在中部连续向外侧流动的效果，则污泥可流动性靠近导料筒51的内壁位置，从而可保障污泥快速实现脱水的效果，旋转驱动单元4上设置有用于驱动螺旋叶片53转动的降速传动单元6，外筒体1上设置有排泥结构7，且排泥结构7贯穿外筒体1并延伸至离心筒3内。Referring to FIGS. 1 to 4 , the utility model provides a sludge dewatering device, including an outer cylinder 1, a centrifugal cylinder 3 is rotatably connected to the outer cylinder 1 through a bearing 2, two groups of bearings 2 are provided in the present application, which are respectively distributed at the top and bottom positions of the outer surface of the centrifugal cylinder 3, so that the rotation stability can be improved when the centrifugal cylinder 3 rotates, a rotary drive unit 4 for driving the centrifugal cylinder 3 to rotate centrifugally is provided on the outer cylinder 1, a sludge turbulence structure 5 is provided in the centrifugal cylinder 3, and the sludge turbulence structure 5 includes a guide cylinder 51 fixedly connected to the bottom of the inner side of the centrifugal cylinder 3, a mud inlet groove 52 provided on the guide cylinder 51, and a spiral Blade 53, when the sludge enters the guide barrel 51, the rotation of the spiral blade 53 can make the sludge in the guide barrel 51 continuously transported upward until it is transported to the end of the guide barrel 51 and can continue to enter the centrifugal barrel 3, so that the sludge in the centrifugal barrel 3 can achieve the effect of continuous flow from the middle to the outside, and the sludge can flow close to the inner wall position of the guide barrel 51, thereby ensuring that the sludge can be quickly dehydrated. The rotary drive unit 4 is provided with a speed reduction transmission unit 6 for driving the spiral blade 53 to rotate, and the outer barrel 1 is provided with a mud discharge structure 7, and the mud discharge structure 7 passes through the outer barrel 1 and extends into the centrifugal barrel 3.
外筒体1的顶部设置有污泥进管8，污泥进管8可借助外部泵送设备将需要脱水的污泥送入外筒体1内的离心筒3中，且外筒体1的底部设置有排液斗9，排液斗9可便于排出经离心筒3离心脱水的污水。A sludge inlet pipe 8 is arranged at the top of the outer cylinder 1, and the sludge inlet pipe 8 can deliver the sludge to be dehydrated into the centrifugal cylinder 3 in the outer cylinder 1 with the help of external pumping equipment, and a drainage bucket 9 is arranged at the bottom of the outer cylinder 1, and the drainage bucket 9 can facilitate the discharge of the sewage dehydrated by the centrifugal cylinder 3.
离心筒3上开设有脱水孔31，且脱水孔31内设置有滤芯，脱水孔31的设置可为污泥提供脱水通道，而滤芯的设置可增加污泥的过滤效果，保障水与泥分离的质量。The centrifugal cylinder 3 is provided with a dehydration hole 31, and a filter element is arranged in the dehydration hole 31. The setting of the dehydration hole 31 can provide a dehydration channel for the sludge, and the setting of the filter element can increase the filtering effect of the sludge and ensure the quality of separation of water and mud.
旋转驱动单元4包括固定连接在外筒体1外表面的驱动电机41、固定连接在驱动电机41动力输出端的传动齿轮42和啮合连接在传动齿轮42上的齿环43，齿环43固定连接在离心筒3的外表面上。The rotation drive unit 4 includes a drive motor 41 fixedly connected to the outer surface of the outer cylinder 1, a transmission gear 42 fixedly connected to the power output end of the drive motor 41, and a gear ring 43 meshingly connected to the transmission gear 42, and the gear ring 43 is fixedly connected to the outer surface of the centrifugal cylinder 3.
具体的，以驱动驱动电机41，其可带动传动齿轮42啮合传动齿环43，这样齿环43的转动可使得离心筒3在轴承2的转动支撑下对污泥进行离心式的脱水处理。Specifically, the driving motor 41 is driven to drive the transmission gear 42 to engage the transmission gear ring 43 , so that the rotation of the gear ring 43 can enable the centrifugal drum 3 to perform centrifugal dehydration treatment on the sludge under the rotation support of the bearing 2 .
螺旋叶片53通过转轴转动连接在外筒体1和离心筒3上，螺旋叶片53通过转轴连接在外筒体1和离心筒3，这样在螺旋叶片53转动时可更加稳定，且螺旋叶片53的顶部低于离心筒3的上沿位置，这样设计的好处是，在螺旋叶片53输送导料筒51内的污泥时，可有效的避免污泥传输而飞溅于离心筒3外的问题。The spiral blade 53 is rotatably connected to the outer cylinder 1 and the centrifugal cylinder 3 through a rotating shaft. The spiral blade 53 is connected to the outer cylinder 1 and the centrifugal cylinder 3 through a rotating shaft, so that the spiral blade 53 can be more stable when rotating, and the top of the spiral blade 53 is lower than the upper edge of the centrifugal cylinder 3. The advantage of this design is that when the spiral blade 53 transports the sludge in the guide cylinder 51, the problem of sludge being transferred and splashing outside the centrifugal cylinder 3 can be effectively avoided.
降速传动单元6包括固定连接外筒体1上的减速齿轮箱61和传动连接在减速齿轮箱61和螺旋叶片53转轴上的皮带轮传动机构62，传动齿轮42的轴端固定连接在减速齿轮箱61的动力输入轴上，本申请中减速齿轮箱61的动力输出轴通过皮带轮传动机构62穿螺旋叶片53进行转动。The speed reduction transmission unit 6 includes a reduction gear box 61 fixedly connected to the outer cylinder 1 and a pulley transmission mechanism 62 that is transmission-connected to the reduction gear box 61 and the rotating shaft of the spiral blade 53. The shaft end of the transmission gear 42 is fixedly connected to the power input shaft of the reduction gear box 61. In the present application, the power output shaft of the reduction gear box 61 rotates through the spiral blade 53 via the pulley transmission mechanism 62.
具体的，在离心筒3旋转对污泥进行离心脱水时，减速齿轮箱61可获取传动齿轮42上的动力，并进行减速处理，这样所输出的动力可通过皮带轮传动机构62来带动螺旋叶片53相对的低速旋转，因离心筒3的污泥可通过进泥槽52进入导料筒51内，这样旋转的螺旋叶片53可在导料筒51内对污泥进行向上的传输，直至位于导料筒51的底部位置后污泥可进入进入离心筒3内进行脱水处理，通过反复对离心筒3内的污泥进行从内向外的翻涌，这样污泥均可通过脱水孔31的位置进行离心的脱水处理。Specifically, when the centrifugal drum 3 rotates to centrifugally dehydrate the sludge, the reduction gear box 61 can obtain the power from the transmission gear 42 and perform a reduction process, so that the output power can drive the spiral blade 53 to rotate at a relatively low speed through the pulley transmission mechanism 62. Because the sludge in the centrifugal drum 3 can enter the guide drum 51 through the mud inlet groove 52, the rotating spiral blade 53 can transfer the sludge upward in the guide drum 51 until it is located at the bottom position of the guide drum 51. The sludge can then enter the centrifugal drum 3 for dehydration treatment. By repeatedly churning the sludge in the centrifugal drum 3 from the inside to the outside, the sludge can be centrifugally dehydrated through the position of the dehydration hole 31.
排泥结构7包括固定连接在外筒体1底部的污泥泵71、设置在污泥泵71一端的导泥管72和固定连接在导泥管72上的刮板73，导泥管72固定贯穿外筒体1并延伸至离心筒3内，刮板73活动接触在离心筒3的内壁上，刮板73的设置，在离心筒3旋转时，刮板73可刮动离心筒3内壁上的污泥，这样在需要下料污泥时，可提高污泥下料的彻底性。The sludge discharge structure 7 includes a sludge pump 71 fixedly connected to the bottom of the outer cylinder 1, a sludge guide pipe 72 arranged at one end of the sludge pump 71, and a scraper 73 fixedly connected to the sludge guide pipe 72. The sludge guide pipe 72 is fixedly passed through the outer cylinder 1 and extends into the centrifugal cylinder 3. The scraper 73 is movably in contact with the inner wall of the centrifugal cylinder 3. The scraper 73 is arranged so that when the centrifugal cylinder 3 rotates, the scraper 73 can scrape the sludge on the inner wall of the centrifugal cylinder 3, so that when it is necessary to discharge the sludge, the thoroughness of the sludge discharge can be improved.
具体的，在污泥通过离心筒3脱水后，遗留在离心筒3内的污泥可由污泥泵71抽出，此过程中可继续控制离心筒3转动，这样刮板73可作用在离心筒3的内壁上来刮除附着的内壁，这样污泥泵71可通过导泥管72彻底且有效的清除离心筒3内经脱水的污泥。Specifically, after the sludge is dehydrated through the centrifugal drum 3, the sludge remaining in the centrifugal drum 3 can be pumped out by the sludge pump 71. During this process, the rotation of the centrifugal drum 3 can continue to be controlled, so that the scraper 73 can act on the inner wall of the centrifugal drum 3 to scrape off the attached inner wall, so that the sludge pump 71 can thoroughly and effectively remove the dehydrated sludge in the centrifugal drum 3 through the mud guide pipe 72.
