设备运行原理：
Operation principle of equipment：

上图所示为带式真空过滤机工作原理。浆料由加料装A均布于向前转动的滤布I上，在真空抽力的作用下，滤液穿过滤布并通过橡胶过滤带H的排液槽进入真空盒J，再通过滤液总管进入气液分离器E中收集排放或回收。被截留的固液在滤布上形成滤饼经过抽干卸料。完成卸料后的滤布通过滤布清洗装置D进行再生，进入下一个环节的过滤,设备上能对过滤母液和洗涤液实现分段收集，滤饼的洗涤可以以顺流和逆流(如图)的方式洗涤，带速可在一定范围上无级调速。整个喂料过滤，洗涤，抽干，卸料，滤布再生可以连续自动完成，并可实现远程自动控制和操作。
The above figure shows the working principle of the belt vacuum filter. The slurry is distributed on the forward rotating filter cloth I by charging A. Under the action of vacuum pumping force, the filtrate passes through the filter cloth and enters the vacuum box J through the rubber filter tank with H, and then enters the gas-liquid separator E through the filtrate main pipe for collection, discharge or recovery. The trapped solid liquid forms a cake on the filter cloth and is drained and discharged. After discharge, the filter cloth is regenerated through the filter cloth cleaning device D, and enters the filtration of the next step. The filter mother liquid and washing liquid can be collected in stages on the device. The filter cake can be washed in the way of upstream and upstream (as shown in the figure), meanwhile, the speed can be adjusted in a certain range. The whole process of feed filtration, washing, draining, unloading, filter cloth regeneration can be completed continuously and automatically, and it can achieve remote automatic control and operation.

橡胶过滤带及裙边、挡板 Rubber filter belt and skirt, baffle

橡胶过滤带又称真空皮带，它是RBF带式真空过滤机配套的关键部件。过滤带骨架材料选用性能优异的聚酯帆布；具有强力高、耐酸碱、耐热、耐油、耐寒等特点，其中最显著的特点就是定负荷伸长小，不易产生变形。过滤带上、下覆盖胶可根据工况条件采用不同的配方，满足耐酸碱、耐热、耐油、耐寒等不同需求；过滤带成型和硫化采用一次整体复合工艺，确保带体的平整和性能的稳定。
The rubber filter belt is also known as the vacuum belt, which is the key component of the RBF belt vacuum filter. Filter belt skeleton material selection of excellent performance polyester canvas; It has the characteristics of high strength, acid and alkali resistance, heat resistance, oil resistance, cold resistance and etc. The most remarkable feature is that the constant load elongation is small, and it is not easy to produce deformation. The filter belt and the lower cover rubber can be formulated according to the working conditions to meet the different needs of acid and alkali resistance, heat resistance, oil resistance, cold resistance and etc. The molding and vulcanization of the filter belt adopt a single integral composite process to ensure the smooth and stable performance of the belt.
为防止滤液的流溢，过滤带两边增加有波形裙边，这种结构的裙边伸缩性好，可以避免裙边经过辊筒改向破裂。过滤带的上部构造为中间设有一排排沟槽，作为排液带。沟槽中部有一排或多排排液孔，可把液体收集在真空箱内。排液孔部位采用纯胶结构，阻隔了酸碱液通过布层渗入使滤带分层，提高了过滤带使用寿命。
In order to prevent the overflow of the filtrate, the two sides of the filter belt are added with the wavy skirt edge. The skirt edge of this structure is good, which can avoid the skirt side through the roller to break. The upper structure of the filter belt is equipped with rows of grooves in the middle, as the drainage belt. There are one or more rows of liquid drainage holes in the middle of the trench, which can collect the liquid in a vacuum tank. The drainage hole adopts pure glue structure, which prevents the acid and alkali solution from infiltrating through the cloth layer and improves the service life of the filter belt.
