CJWA自动洗涤压滤机产品先容

CJWA Automatic Washing Filter Press

  CJWA自动洗涤压滤机是具有给料过滤、无隔膜压榨过滤、无短路洗涤、高效吹干过滤的高效脱水及洗涤流程的新型过滤设备。该设备在达到更优滤饼含水率及洗涤指标的条件下,取代现有常规的两段或多段联合洗涤脱水工艺,实现选矿、冶炼、黄金浸出、锂盐、冶炼等行业洗涤、过滤无短路一体化,从而大幅缩短工艺流程,减化设置配置,节约厂房及操作工人,减少有害物质的二次污染,提升有价资源的回收率,降低投资及运行成本,提升企业的经济及社会效益。

  CJWA automatic washing filter press is a new type of filtration equipment with high efficiency dewatering and washing process: feeding, diaphragmless pressing, no short-circuit washing, high efficiency blow drying. The equipment replaces the conventional two-stage or multi-stage process combined washing and dewatering under the condition of achieving better filter cake moisture content and washing index, and realizes no short circuit washing and filtering in mineral processing, smelting, leaching gold, lithium salt and other industries, which greatly shortens the process, saves space and labor, reduces the auxiliary equipment configuration, the probability of secondary pollution, investment and operating costs, improves the recovery rate of valuable resources, and enhances the economic and social benefits of enterprises.

工作原理

  CJWA自动洗涤压滤机采用无中心孔独特设计,直接杜绝中心孔洗涤不到,或者洗涤工序复杂等问题,实现滤饼洗涤率远高于同类产品,且洗涤滤饼均匀。(箱式和箱式隔膜压滤机采用中心孔进料方式,洗涤和空气吹干均存在短路现象,无法有效洗涤和吹干也是其他压滤机洗涤水耗量大,且洗涤不均匀的原因)。

Filter Principle

  The CJWA automatic washing filter press adopts a unique feeding design without a central hole to directly eliminate the problem that the central hole is not washed, or the washing process is complicated, reaching much higher washing rate than that of similar products, and uniform washing effect. (The box type and box type diaphragm filter press adopts the central hole feeding mode, which results in the short-circuit phenomenon in washing and blowing process results, that is the reason other filter press cannot reach uniform washing and need large water consumption.)

  1、给料过滤即依靠渣浆泵的输送压力,使进入滤室的矿渣被滤布截留,形成滤饼;水透过滤布排除,实现固液分离;

  2、压榨过滤是在给料过滤形成的疏松滤饼一侧施加压力,收缩其空隙,排除空隙中的水;

  3、无短路洗涤是采用长杰独特的在线洗涤方式,通过洗涤泵将洗涤液均匀穿透滤饼,实现滤饼各点洗涤效果相同,减少耗水量、提高洗涤率;

  4、吹干过滤是采用介质高速穿过滤饼间歇,带走间歇水,进一步降低滤饼含水率。无论采用多大的压滤压榨滤饼,滤饼的间隙也不能完全消除,因此,增加吹干过滤,用高压空气分钟透过滤饼间隙并带走滤饼间隙中的水分,是降低滤饼含水率的重要手段。然而有效的防止吹干时压缩空气短路,却是能否实现有效吹干的关键。

  1. The feed filtration is based on the delivery pressure of the slurry pump, so that the slag entering the filter chamber is trapped by the filter cloth to form a filter cake; the water is filtered through the filter cloth to achieve solid-liquid separation;

  2. Press filtration is to press on the side of the porous filter cake formed by the feed filtration, shrinking the voids and eliminating the water in the voids;

  3. No short-circuit washing is based on Changjie's unique online (while washing without unloading filter cake) washing method, washing liquid evenly penetrates the filter cake by the washing pump to reach the same washing effect at each point of filter cake, reducing the water consumption and increasing the washing rate;

  4. Dry-blowing filtration uses high-speed compressed air to pass through the cake and remove intermittent water, further reducing the moisture content of the cake. Regardless of how much pressure is used to press the filter cake, the gap between the material particles cannot be completely eliminated. Therefore, the dry-blowing filtration, using high-pressure air to pass through the cake and remove moisture from the particles gap, which is the important means to reduce the moisture content of the filter cake. However, effective prevention of short-circuit of compressed air during drying is the key to effective drying.

Application Field

  Changjie washing filter press integrates washing and filtering on one machine. While ensuring low water content of filter cakes and high productivity, it realizes effective washing of filter cakes, with the washing rate of as high as 99.5%. It also greatly saves washing water, improves the recovery rate of valuable resources in filtrate, reduces the amount of wastewater to be treated, and provides strong supports for shortening production process, reducing cost and increasing efficiency in lithium salt, gold, hydrometallurgy and chemical industries.

  1. Lithium salt washing and filtration

  Changjie washing filter press realizes the integration of washing and filtering of lithium salt and makes the water content in filter cakes less than 15%. With this kind of filter press adopted, the lithium slag content is one order of magnitude lower than that of the original filtering-agitator treating-filtering process, and water is less consumed. The filter cake drying process which was added in the original process is cancelled after using Changjie washing and filtering machine, the process flow is shortened, the equipment investments are reduced, and the production costs are greatly reduced.

  2. Gold washing and filtration

  In view of the high cyanide content in gold tailings and leaching residues, Changjie washing filter press adopts the counter-current scrubbing process, with which the cyanide removal rate of gold ore reaches 99.5% without using catalyst, ensuring that the cyanide content of filter cakes is reduced to less than 0.5 mg/l, which effectively avoids the secondary pollution, directly meets the class-I national  environmental protection discharge standard of gold tailings, and greatly improves the recovery rate of gold in filtrate.

  3. Hydrometallurgy washing and filtration

  Through the high-efficiency washing without short circuit, the content of valuable compositions in filter residue is greatly reduced, and the multi-stage filtering and washing-re-filtering-rewashing is shortened and completed one machine. While increasing the yield of valuable compositions, the whole operation process is shortened, which provides strong support for owners to reduce the costs of infrastructure, procurement, management and operation.
