The intelligent and efficient filter press is developed from the traditional filter press. Unlike the box-type diaphragm filter press, it is a new type of filter device combining the latest intelligent control technology with the filter press of the filter system. This type of filter press uses a specially designed filter system to reduce the moisture content of the filter cake to ensure better discharge. At the same time, the intelligent induction control system is added. When the parameters such as concentration, fineness and viscosity of the filter material change, the pressure is changed. The filter itself independently and intelligently regulates important parameters such as feeding time, feed pressure, press pressure, press time, blow dry time and water content of the filter cake, so that the filter press can automatically adapt to the filtration requirements under various conditions to ensure The water content of each filter cake meets the requirements of automatic discharge; at the same time, it detects the failure of the equipment autonomously, and realizes the autonomous, intelligent and automatic operation of the filter press.

First, intelligent and efficient filter press technical characteristics
1. The product has a low moisture content: The final moisture content of the material can be less than 6%, and the flotation fine tailings such as copper, lead, zinc, silver, antimony, molybdenum, phosphorus, and gold can be filtered. The economic moisture content can be <10%.
2. High production capacity: Under the same conditions, the production capacity per unit area can be 5-10 times higher than ordinary box or frame filter presses. The maximum production capacity of individual manufacturers can handle 10,000 tons of dry slag every day, saving users a lot of land acquisition, plant and Infrastructure investment.
3, simple structure, long life. Thrust plates, pressure plates, main beams, beams, and normal use are guaranteed to be free from fracture for 5 years.
4, adaptable. High altitude (above 5000m), low concentration (feed concentration 15%), and fine particles (-400 mesh accounted for 100%) all have running examples, and the filter cake moisture content is still less than 10%.
5. Intelligent control: Through PLC+ touch screen intelligent control, a single operation cycle (pressing filter plate, feeding, pipe cleaning, pressing, drying, pulling and discharging) can be completed automatically with one key, greatly reducing the labor intensity. .
6, compatible with many functions: dehydration washing can be completed in one machine, and part of the ore dressing process, can be removed directly thickening machine filter, reduce or cancel the drying equipment investment, saving a lot of investment for the user.
7, the overall cost is low. The equipment has simple structure, few wearing parts and no diaphragm pressing. Under the same processing scale, the production cost is much lower than the ordinary box diaphragm and plate and frame filter press, and the investment recovery is fast.
Second, the major domestic and foreign manufacturers of such equipment foreign suppliers are mainly Metso Metso, Outotec Outotec, etc., the domestic suppliers are mainly Zhangzhou Changjie Filtration Equipment Co., Ltd. (), these manufacturers of smart and efficient filter press The salient features are: the rapid reduction of moisture content and easy removal of the filter cake, combined with intelligent control system, to achieve a fast and efficient automatic operation of the filter press. The above manufacturers have different designs for reducing the moisture content of the filter cake and automatic filter cake dropping. However, the overall idea of ​​automatic operation of the filter cake is the same.
1, Metso Metso: headquartered in Finland, the world's leading integrated engineering and technology company, the main production of vertical plate filter press VPA, a high degree of automation, low moisture content, but the equipment prices and spare parts prices are also very expensive, domestic typical users It is a large state-owned mining company such as TISCO, Anshan Iron and Steel, Haikou Phosphorus Mine, and Shandong Gold.
2, Outotec Outotec: Headquartered in Finland, can provide technology and services from the mineral to the metal industry chain, its main production LAROX-PF automatic filter press and FFP quick-open filter press, high degree of automation, low moisture content However, the equipment and spare parts prices are extremely expensive, and some domestic scenes are not satisfactory. Typical users are Jinchuan Group (currently replaced by CJZJ equipment of Zhangzhou Changjie Filtration Equipment Co., Ltd.), Yunnan Copper (unsatisfactory use), Chinalco Shandong and so on.
3. Changjie Filtration Changjiechina: Headquartered in Luzhou, Sichuan, China, is a domestic supplier specializing in the R&D and production of intelligent and efficient filter presses. Its CJR, CJZJ and other intelligent high-efficiency filter presses and CJX washing and filtering integrated machines are used. The unique design of the external feeding ensures three-stage complete filtration, realizes the integration of no-separator pressing and washing and filtration, and achieves full intelligent control of filtration parameters, low moisture content, high first-time washing rate, high productivity, and original cyanide removal process. Provides important technical support for the gold tailings dry discharge. CJR series unattended filter presses have a single filtration area of ​​over 2,100 square meters, and the processing capacity of such individual iron ore concentrates exceeds 10,000 tons, setting a record for multi-industry filtration. Typical users are Jinchuan Group, China National Gold Group (such as Wushan Copper-Molybdenum Mine, Baotou Xinda Gold Tailings, etc.), Western Mining Group (such as Yulong Copper Mine, Yucun Multi-metal Mine, etc.), Zijin Group (Delene Copper Mine) , Weinan Zijin Gold Concentrate, Wuhou Zijin Lead-zinc Concentrate, etc.), Xingfa Group (phosphorous tailings), Wanguo Mining (copper tailings), etc.
III. Equipment Components The equipment consists of the following components: high-efficiency filtration system, high-efficiency rack system, high-efficiency hydraulic system, intelligent control system, fault diagnosis, and unattended system to realize automatic control of the entire process parameters for filtration, and achieve continuous and stable low moisture content. And high productivity. More technical details require the above manufacturer's advice.
Under the background of the new normal mining industry, along with the intensification of mineral processing, leanness and miscellaneous, the environmental protection requirements for tailings are getting higher and higher, effective washing and filtration becomes increasingly difficult, and high-quality, cost-effective, and high-intelligent pressures are selected. Filters are increasingly important. As a new choice for enterprises to reduce costs and increase efficiency, intelligent and efficient filter presses will certainly play a greater role in concentrate filtration, tail storage and comprehensive utilization.

Anti-corrosion refers to the protection of metal surfaces from corroding in high-risk (corrosive) environments.
When metallic materials are put into corrosive environments, they tend to have chemical reactions with the air and/or water. The effects of corrosion become evident on the surfaces of these materials. For example, after putting a piece of iron into a corrosive atmosphere for an extended period, it starts rusting due to oxygen interaction with water on the surface of the piece of iron.
