設備運行原理：
Operation principle of equipment：

上圖所示為帶式真空過濾機工作原理。漿料由加料裝A均布于向前轉(zhuǎn)動的濾布I上，在真空抽力的作用下，濾液穿過濾布并通過橡膠過濾帶H的排液槽進入真空盒J，再通過濾液總管進入氣液分離器E中收集排放或回收。被截留的固液在濾布上形成濾餅經(jīng)過抽干卸料。完成卸料后的濾布通過濾布清洗裝置D進行再生，進入下一個環(huán)節(jié)的過濾,設備上能對過濾母液和洗滌液實現(xiàn)分段收集，濾餅的洗滌可以以順流和逆流(如圖)的方式洗滌，帶速可在一定范圍上無級調(diào)速。整個喂料過濾，洗滌，抽干，卸料，濾布再生可以連續(xù)自動完成，并可實現(xiàn)遠程自動控制和操作。
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.

橡膠過濾帶及裙邊、擋板 Rubber filter belt and skirt, baffle

橡膠過濾帶又稱真空皮帶，它是RBF帶式真空過濾機配套的關(guān)鍵部件。過濾帶骨架材料選用性能優(yōu)異的聚酯帆布；具有強力高、耐酸堿、耐熱、耐油、耐寒等特點，其中最顯著的特點就是定負荷伸長小，不易產(chǎn)生變形。過濾帶上、下覆蓋膠可根據(jù)工況條件采用不同的配方，滿足耐酸堿、耐熱、耐油、耐寒等不同需求；過濾帶成型和硫化采用一次整體復合工藝，確保帶體的平整和性能的穩(wěn)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.
為防止濾液的流溢，過濾帶兩邊增加有波形裙邊，這種結(jié)構(gòu)的裙邊伸縮性好，可以避免裙邊經(jīng)過輥筒改向破裂。過濾帶的上部構(gòu)造為中間設有一排排溝槽，作為排液帶。溝槽中部有一排或多排排液孔，可把液體收集在真空箱內(nèi)。排液孔部位采用純膠結(jié)構(gòu)，阻隔了酸堿液通過布層滲入使濾帶分層，提高了過濾帶使用壽命。
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.
